I. Executive Summary and Background

A. Executive Summary

1. Purpose and Legal Authority
    This FY 2025 IPPS/LTCH PPS proposed rule would make payment and 
policy changes under the Medicare inpatient prospective payment system 
(IPPS) for operating and capital-related costs of acute care hospitals 
as well as for certain hospitals and hospital units excluded from the 
IPPS. In addition, it would make payment and policy changes for 
inpatient hospital services provided by long-term care hospitals 
(LTCHs) under the long-term care hospital prospective payment system 
(LTCH PPS). This proposed rule also would make policy changes to 
programs associated with Medicare IPPS hospitals, IPPS-excluded 
hospitals, and LTCHs. In this FY 2025 proposed rule, we are proposing 
to continue policies to address wage index disparities impacting low 
wage index hospitals. We are also proposing changes relating to 
Medicare graduate medical education (GME) for teaching hospitals and 
new technology add-on payments.
    We are proposing a separate IPPS payment for establishing and 
maintaining access to essential medicines.
    In the Hospital Value-Based Purchasing (VBP) Program, we are 
proposing to modify scoring of the Person and Community Engagement 
Domain for the FY 2027 through FY 2029 program years to only score six 
unchanged dimensions of the Hospital Consumer Assessment of Healthcare 
Providers and Systems (HCAHPS) Survey, and we are proposing to adopt 
the updated HCAHPS Survey in the Hospital VBP Program beginning with 
the FY 2030 program year after the updated survey would have been 
publicly reported under the Hospital Inpatient Quality Reporting (IQR) 
Program for 1 year. We are also proposing to modify scoring on the 
HCAHPS Survey beginning with the FY 2030 program year to incorporate 
the updated HCAHPS Survey measure into nine survey dimensions. Lastly, 
we are providing previously and newly established performance standards 
for the FY 2027 through FY 2030 program years for the Hospital VBP 
Program.
    In the Hospital IQR Program, we are proposing to add seven new 
measures, modify two existing measures including the HCAHPS Survey 
measure, and remove five measures. We are also proposing changes to the 
reporting and submission requirements for electronic clinical quality 
measures (eCQMs) and the validation process for the Hospital IQR 
Program data.
    In the PPS-Exempt Cancer Hospital Quality Reporting Program 
(PCHQR), we are proposing to adopt the Patient Safety Structural 
measure beginning with the CY 2025 reporting period/FY 2027 program 
year. We are also proposing to modify the HCAHPS Survey measure and to 
move up the start date for publicly displaying hospital performance on 
the Hospital Commitment to Health Equity measure.
    In the LTCH QRP, we are proposing to add four items to the LTCH 
Continuity Assessment Record and Evaluation (CARE) Data Set (LCDS) and 
modify one item on the LCDS beginning with the FY 2028 LTCH QRP. 
Additionally, we are proposing to extend the admission assessment 
window for the LCDS beginning with the FY 2028 LTCH QRP. Finally, we 
are seeking information on future measure concepts for the LTCH QRP and 
a future LTCH Star Rating system.
    In the Medicare Promoting Interoperability Program, we are 
proposing to separate the Antimicrobial Use and Resistance (AUR) 
Surveillance measure into two measures, an Antimicrobial Use (AU) 
Surveillance measure and an Antimicrobial Resistance (AR) Surveillance 
measure, beginning with the electronic health record (EHR) reporting 
period in CY 2025. We are proposing to increase the performance-based 
scoring threshold from 60 to 80 points beginning with the EHR reporting 
period in CY 2025. We are proposing to adopt two new eCQMs and modify 
one eCQM, in alignment with the Hospital IQR Program. Finally, we are 
proposing changes to the reporting and submission requirements for 
eCQMs, in alignment with the Hospital IQR Program.
    The Transforming Episode Accountability Model (TEAM) proposes the 
creation and testing of a new mandatory alternative payment model. The 
intent of TEAM is to improve beneficiary care through financial 
accountability for episodes categories that begin with one of the 
following procedures: coronary artery bypass graft (CABG), lower 
extremity joint replacement (LEJR), major bowel procedure, surgical 
hip/femur fracture treatment (SHFFT), and spinal fusion. TEAM would 
test whether financial accountability for these episode categories 
reduces Medicare expenditures while preserving or enhancing the quality 
of care for Medicare beneficiaries. We anticipate that TEAM would 
benefit Medicare beneficiaries through improving the coordination of 
items and services paid for through Medicare fee-for-service (FFS) 
payments, encouraging provider investment in health care infrastructure 
and redesigned care processes, and incentivizing higher value care 
across the inpatient and post-acute care settings for the episode. We 
propose to test TEAM for a 5-year model performance period, beginning 
January 1, 2026, and ending December 31, 2030. Under the Quality 
Payment Program (QPP), we anticipate that TEAM would be an Advanced 
Alternative Payment Model (APM)for Track 2 and Track 3 and a Merit-
based Incentive Payment System (MIPS) APM for all participation tracks.
    Under various statutory authorities, we either discuss continued 
program implementation or propose to make changes to the Medicare IPPS, 
the LTCH PPS, other related payment methodologies and programs for FY 
2025 and subsequent fiscal years, and

[[Page 35936]]

other policies and provisions included in this rule. These statutory 
authorities include, but are not limited to, the following:
     Section 1886(d) of the Social Security Act (the Act), 
which sets forth a system of payment for the operating costs of acute 
care hospital inpatient stays under Medicare Part A (Hospital 
Insurance) based on prospectively set rates. Section 1886(g) of the Act 
requires that, instead of paying for capital-related costs of inpatient 
hospital services on a reasonable cost basis, the Secretary use a 
prospective payment system (PPS).
     Section 1886(d)(1)(B) of the Act, which specifies that 
certain hospitals and hospital units are excluded from the IPPS. These 
hospitals and units are: rehabilitation hospitals and units; LTCHs; 
psychiatric hospitals and units; children's hospitals; cancer 
hospitals; extended neoplastic disease care hospitals; and hospitals 
located outside the 50 States, the District of Columbia, and Puerto 
Rico (that is, hospitals located in the U.S. Virgin Islands, Guam, the 
Northern Mariana Islands, and American Samoa). Religious nonmedical 
health care institutions (RNHCIs) are also excluded from the IPPS.
     Sections 123(a) and (c) of the Balanced Budget Refinement 
Act of 1999 (BBRA) (Public Law (Pub. L.) 106-113) and section 307(b)(1) 
of the Benefits Improvement and Protection Act of 2000 (BIPA) (Pub. L. 
106-554) (as codified under section 1886(m)(1) of the Act), which 
provide for the development and implementation of a prospective payment 
system for payment for inpatient hospital services of LTCHs described 
in section 1886(d)(1)(B)(iv) of the Act.
     Section 1814(l)(4) of the Act requires downward 
adjustments to the applicable percentage increase, beginning with FY 
2015, for CAHs that do not successfully demonstrate meaningful use of 
certified electronic health record technology (CEHRT) for an EHR 
reporting period for a payment adjustment year.
     Section 1886(a)(4) of the Act, which specifies that costs 
of approved educational activities are excluded from the operating 
costs of inpatient hospital services. Hospitals with approved graduate 
medical education (GME) programs are paid for the direct costs of GME 
in accordance with section 1886(h) of the Act. Hospitals paid under the 
IPPS with approved GME programs are paid for the indirect costs of 
training residents in accordance with section 1886(d)(5)(B) of the Act.
     Section 1886(d)(5)(F) of the Act provides for additional 
Medicare IPPS payments to subsection (d) hospitals that serve a 
significantly disproportionate number of low-income patients. These 
payments are known as the Medicare disproportionate share hospital 
(DSH) adjustment. Section 1886(d)(5)(F) of the Act specifies the 
methods under which a hospital may qualify for the DSH payment 
adjustment.
     Section 1886(b)(3)(B)(viii) of the Act, which requires the 
Secretary to reduce the applicable percentage increase that would 
otherwise apply to the standardized amount applicable to a subsection 
(d) hospital for discharges occurring in a fiscal year if the hospital 
does not submit data on measures in a form and manner, and at a time, 
specified by the Secretary.
     Section 1886(b)(3)(B)(ix) of the Act, which requires 
downward adjustments to the applicable percentage increase, beginning 
with FY 2015 (and beginning with FY 2022 for subsection (d) Puerto Rico 
hospitals), for eligible hospitals that do not successfully demonstrate 
meaningful use of CEHRT for an EHR reporting period for a payment 
adjustment year.
     Section 1866(k) of the Act, which provides for the 
establishment of a quality reporting program for hospitals described in 
section 1886(d)(1)(B)(v) of the Act, referred to as ``PPS-exempt cancer 
hospitals.''
     Section 1886(n) of the Act, which establishes the 
requirements for an eligible hospital to be treated as a meaningful EHR 
user of CEHRT for an EHR reporting period for a payment adjustment year 
or, for purposes of subsection (b)(3)(B)(ix) of the Act, for a fiscal 
year.
     Section 1886(o) of the Act, which requires the Secretary 
to establish a Hospital Value-Based Purchasing (VBP) Program, under 
which value-based incentive payments are made in a fiscal year to 
hospitals based on their performance on measures established for a 
performance period for such fiscal year.
     Section 1886(p) of the Act, which establishes a Hospital-
Acquired Condition (HAC) Reduction Program, under which payments to 
applicable hospitals are adjusted to provide an incentive to reduce 
hospital-acquired conditions.
     Section 1886(q) of the Act, as amended by section 15002 of 
the 21st Century Cures Act, which establishes the Hospital Readmissions 
Reduction Program. Under the program, payments for discharges from an 
applicable hospital as defined under section 1886(d) of the Act will be 
reduced to account for certain excess readmissions. Section 15002 of 
the 21st Century Cures Act directs the Secretary to compare hospitals 
with respect to the number of their Medicare-Medicaid dual-eligible 
beneficiaries in determining the extent of excess readmissions.
     Section 1886(r) of the Act, as added by section 3133 of 
the Affordable Care Act, which provides for a reduction to 
disproportionate share hospital (DSH) payments under section 
1886(d)(5)(F) of the Act and for an additional uncompensated care 
payment to eligible hospitals. Specifically, section 1886(r) of the Act 
requires that, for fiscal year 2014 and each subsequent fiscal year, 
subsection (d) hospitals that would otherwise receive a DSH payment 
made under section 1886(d)(5)(F) of the Act will receive two separate 
payments: (1) 25 percent of the amount they previously would have 
received under the statutory formula for Medicare DSH payments in 
section 1886(d)(5)(F) of the Act if subsection (r) did not apply (``the 
empirically justified amount''), and (2) an additional payment for the 
DSH hospital's proportion of uncompensated care, determined as the 
product of three factors. These three factors are: (1) 75 percent of 
the payments that would otherwise be made under section 1886(d)(5)(F) 
of the Act, in the absence of section 1886(r) of the Act; (2) 1 minus 
the percent change in the percent of individuals who are uninsured; and 
(3) the hospital's uncompensated care amount relative to the 
uncompensated care amount of all DSH hospitals expressed as a 
percentage.
     Section 1886(m)(5) of the Act, which requires the 
Secretary to reduce by 2 percentage points the annual update to the 
standard Federal rate for discharges for a long-term care hospital 
(LTCH) during the rate year for LTCHs that do not submit data on 
quality measures in the form, manner, and at a time, specified by the 
Secretary.
     Section 1886(m)(6) of the Act, as added by section 
1206(a)(1) of the Pathway for Sustainable Growth Rate (SGR) Reform Act 
of 2013 (Pub. L. 113-67) and amended by section 51005(a) of the 
Bipartisan Budget Act of 2018 (Pub. L. 115-123), which provided for the 
establishment of site neutral payment rate criteria under the LTCH PPS, 
with implementation beginning in FY 2016. Section 51005(b) of the 
Bipartisan Budget Act of 2018 amended section 1886(m)(6)(B) by adding 
new clause (iv), which specifies that the IPPS comparable amount 
defined in clause (ii)(I) shall be reduced by 4.6 percent for FYs 2018 
through 2026.
     Section 1899B of the Act, which provides for the 
establishment of standardized data reporting for certain

[[Page 35937]]

post-acute care providers, including LTCHs.
     Section 1115A of the Act authorizes the testing of 
innovative payment and service delivery models that preserve or enhance 
the quality of care furnished to Medicare, Medicaid, and Children's 
Health Insurance Program (CHIP) beneficiaries while reducing program 
expenditures.
2. Summary of the Major Provisions
    The following is a summary of the major provisions in this proposed 
rule. In general, these major provisions are being proposed as part of 
the annual update to the payment policies and payment rates, consistent 
with the applicable statutory provisions. A general summary of the 
changes in this proposed rule is presented in section I.D. of the 
preamble of this proposed rule.
a. Proposed Continuation of the Low Wage Index Hospital Policy
    To help mitigate growing wage index disparities between high wage 
and low wage hospitals, in the FY 2020 IPPS/LTCH PPS rule (84 FR 42326 
through 42332), we adopted a policy to increase the wage index values 
for certain hospitals with low wage index values (the low wage index 
hospital policy). This policy was adopted in a budget neutral manner 
through an adjustment applied to the standardized amounts for all 
hospitals. We indicated our intention that this policy would be 
effective for at least 4 years, beginning in FY 2020, in order to allow 
employee compensation increases implemented by these hospitals 
sufficient time to be reflected in the wage index calculation. As 
discussed in section III.G.5. of the preamble of this proposed rule, 
while we are using the FY 2021 cost report data for the FY 2025 wage 
index, we are unable to comprehensively evaluate the effect, if any, 
the low wage index hospital policy had on hospitals' wage increases 
during the years the COVID-19 public health emergency (PHE) was in 
effect. We believe it is necessary to wait until we have useable data 
from fiscal years after the PHE before reaching any conclusions about 
the efficacy of the policy. Therefore, we are proposing that the low 
wage index hospital policy and the related budget neutrality adjustment 
would be effective for at least three more years, beginning in FY 2025.
b. Proposed Separate IPPS Payment for Establishing and Maintaining 
Access to Essential Medicines
    As discussed in section V.J. of the preamble of this proposed rule, 
the Biden-Harris administration has made it a priority to strengthen 
the resilience of medical supply chains and support reliable access to 
products for public health, including through prevention and mitigation 
of medical product shortages. As a first step in this initiative, we 
are proposing to establish a separate payment for small, independent 
hospitals for the IPPS shares of the additional resource costs to 
voluntarily establish and maintain a 6-month buffer stock of one or 
more of 86 essential medicines, either directly or through contractual 
arrangements with a pharmaceutical manufacturer, distributor, or 
intermediary. For the purposes of this policy, we define small, 
independent hospitals as hospitals with 100 beds or fewer that are not 
part of a chain organization. We are proposing to make this separate 
payment in a non-budget neutral manner under section 1886(d)(5)(I) of 
the Act. We are proposing that the payment adjustments would commence 
for cost reporting periods beginning on or after October 1, 2024.
c. DSH Payment Adjustment, Additional Payment for Uncompensated Care, 
and Supplemental Payment
    Under section 1886(r) of the Act, which was added by section 3133 
of the Affordable Care Act, starting in FY 2014, Medicare 
disproportionate share hospitals (DSHs) receive 25 percent of the 
amount they previously would have received under the statutory formula 
for Medicare DSH payments in section 1886(d)(5)(F) of the Act. The 
remaining amount, equal to 75 percent of the amount that would have 
been paid as Medicare DSH payments under section 1886(d)(5)(F) of the 
Act if subsection (r) did not apply, is paid as additional payments 
after the amount is reduced for changes in the percentage of 
individuals that are uninsured. Each Medicare DSH that has 
uncompensated care will receive an additional payment based on its 
share of the total amount of uncompensated care for all Medicare DSHs 
for a given time period. This additional payment is known as the 
uncompensated care payment.
    In this proposed rule, we are proposing to update our estimates of 
the three factors used to determine uncompensated care payments for FY 
2025. We are also proposing to continue to use uninsured estimates 
produced by CMS' Office of the Actuary (OACT) as part of the 
development of the National Health Expenditure Accounts (NHEA) in 
conjunction with more recently available data in the calculation of 
Factor 2. Consistent with the regulation at Sec.  
412.106(g)(1)(iii)(C)(11), which was adopted in the FY 2023 IPPS/LTCH 
PPS final rule, for FY 2025, we will use the 3 most recent years of 
audited data on uncompensated care costs from Worksheet S-10 of the FY 
2019, FY 2020, and FY 2021 cost reports to calculate Factor 3 in the 
uncompensated care payment methodology for all eligible hospitals.
    Beginning with FY 2023 (87 FR 49047 through 49051), we also 
established a supplemental payment for IHS and Tribal hospitals and 
hospitals located in Puerto Rico. In section IV.D of the preamble of 
this proposed rule, we summarize the ongoing methodology for 
supplemental payments.
    In this proposed rule, we are also proposing, for FY 2025 and 
subsequent fiscal years, to calculate the per-discharge amount for 
interim uncompensated care payments using the average of the most 
recent 3 years of discharge data. Accordingly, for FY 2025, we propose 
to use an average of discharge data from FY 2021, FY 2022, and FY 2023. 
We believe that our proposed approach will likely result in a better 
estimate of the number of discharges during FY 2025 and subsequent 
years for purposes of the interim uncompensated care payment 
calculation. We propose to codify this proposed approach in new Sec.  
412.106(i)(1).
d. Proposed Adoption of the Patient Safety Structural Measure in the 
Hospital IQR Program and PCHQR Program
    The proposed Patient Safety Structural measure is an attestation-
based measure that assesses whether hospitals have a structure and 
culture that prioritizes safety as demonstrated by the following five 
domains: (1) leadership commitment to eliminating preventable harm; (2) 
strategic planning and organizational policy; (3) culture of safety and 
learning health system; (4) accountability and transparency; and (5) 
patient and family engagement. Hospitals would attest to whether they 
engage in specific evidence-based best practices within each of these 
domains to achieve a score from zero to five out of five points. We are 
proposing that hospitals would be required to report this measure 
beginning with the CY 2025 reporting period/FY 2027 program year for 
the PCHQR Program and for the CY 2025 reporting period/FY 2027 payment 
determination for the Hospital IQR Program.

[[Page 35938]]

e. Proposed Updated Hospital Consumer Assessment of Healthcare 
Providers and Systems (HCAHPS) Survey Measure in the Hospital IQR 
Program, Hospital VBP Program, and PCHQR Program
    The proposal to use the updated version of the HCAHPS Survey 
measure aligns with the National Quality Strategy goal to bring patient 
voices to the forefront by incorporating feedback from patients and 
caregivers. The proposed updated HCAHPS Survey measure would be adopted 
for the Hospital IQR and PCHQR Programs beginning with the CY 2025 
reporting period/FY 2027 payment determination and the CY 2025 
reporting period/FY 2027 program year, respectively. For the Hospital 
VBP Program, we are proposing to modify scoring on the Person and 
Community Engagement Domain for the FY 2027 through FY 2029 program 
years to only score six unchanged dimensions of the HCAHPS Survey. We 
are proposing to adopt the updated HCAHPS Survey measure beginning with 
the FY 2030 program year, which would result in nine HCAHPS Survey 
dimensions for the Person and Community Engagement Domain. We are also 
proposing to modify scoring of the Person and Community Engagement 
Domain beginning with the FY 2030 program year to account for the 
proposed updates to the HCAHPS Survey.
f. Hospital Value-Based Purchasing (VBP) Program
    Section 1886(o) of the Act requires the Secretary to establish a 
Hospital VBP Program under which value-based incentive payments are 
made in a fiscal year to hospitals based on their performance on 
measures established for a performance period for such fiscal year. In 
this proposed rule, we are proposing to modify scoring on the Person 
and Community Engagement Domain for the FY 2027 through FY 2029 program 
years while the updated HCAHPS Survey measure would be publicly 
reported under the Hospital IQR Program. In addition, we are proposing 
to adopt the updated HCAHPS Survey measure beginning with the FY 2030 
program year and modify scoring beginning with the FY 2030 program year 
to account for the updated HCAHPS Survey.
g. Hospital Inpatient Quality Reporting (IQR) Program
    Under section 1886(b)(3)(B)(viii) of the Act, subsection (d) 
hospitals are required to report data on measures selected by the 
Secretary for a fiscal year in order to receive the full annual 
percentage increase. In the FY 2025 IPPS/LTCH PPS proposed rule, we are 
proposing several changes to the Hospital IQR Program. We are proposing 
the adoption of seven new measures: (1) Patient Safety Structural 
measure beginning with the CY 2025 reporting period/FY 2027 payment 
determination; (2) Age Friendly Hospital measure beginning with the CY 
2025 reporting period/FY 2027 payment determination; (3) Catheter-
Associated Urinary Tract Infection (CAUTI) Standardized Infection Ratio 
Stratified for Oncology Locations beginning with the CY 2026 reporting 
period/FY 2028 payment determination; (4) Central Line-Associated 
Bloodstream Infection (CLABSI) Standardized Infection Ratio Stratified 
for Oncology Locations beginning with the CY 2026 reporting period/FY 
2028 reporting period; (5) Hospital Harm--Falls with Injury eCQM 
beginning with the CY 2026 reporting period/FY 2028 payment 
determination; (6) Hospital Harm--Postoperative Respiratory Failure 
eCQM beginning with the CY 2026 reporting period/FY 2028 payment 
determination; and (7) Thirty-day Risk-Standardized Death Rate among 
Surgical Inpatients with Complications (Failure-to-Rescue) measure 
beginning with the July 1, 2023-June 30, 2025 reporting period/FY 2027 
payment determination. We are also proposing refinements to two 
measures currently in the Hospital IQR Program measure set: (1) Global 
Malnutrition Composite Score (GMCS) eCQM, beginning with the CY 2026 
reporting period/FY 2028 payment determination; and (2) the HCAHPS 
Survey beginning with the CY 2025 reporting period/FY 2027 payment 
determination. We are also proposing the removal of five measures: (1) 
Death Among Surgical Inpatients with Serious Treatable Complications 
(CMS PSI 04) measure beginning with the July 1, 2023-June 30, 2025 
reporting period/FY 27 payment determination ; (2) Hospital-level, 
Risk-Standardized Payment Associated with a 30-Day Episode-of-Care for 
Acute Myocardial Infarction (AMI) measure beginning with the July 1, 
2021-June 30, 2024 reporting period/FY 2026 payment determination; (3) 
Hospital-level, Risk-Standardized Payment Associated with a 30-Day 
Episode-of-Care for Heart Failure (HF) measure beginning with the July 
1, 2021-June 30, 2024 reporting period/FY 2026 payment determination; 
(4) Hospital-level, Risk-Standardized Payment Associated with a 30-Day 
Episode-of-Care for Pneumonia (PN) measure beginning with July 1, 2021-
June 30, 2024 reporting period/FY 2026 payment determination and (5) 
Hospital-level, Risk-Standardized Payment Associated with a 30-Day 
Episode-of-Care for Elective Primary Total Hip Arthroplasty (THA) and/
or Total Knee Arthroplasty (TKA) measure beginning with the April 1, 
2021-March 31, 2024 reporting period/FY 2026 payment determination.
    We are proposing to modify eCQM data reporting and submission 
requirements by proposing a progressive increase in the number of 
mandatory eCQMs a hospital would be required to report on beginning 
with the CY 2026 reporting period/FY 2028 payment determination. We are 
also proposing two changes to current policies related to validation of 
hospital data: (1) to implement eCQM validation scoring based on the 
accuracy of eCQM data beginning with the validation of CY 2025 eCQM 
data affecting the FY 2028 payment determination; and (2) modification 
of the data validation reconsideration request requirements to make 
medical records submission optional for reconsideration requests 
beginning with CY 2023 discharges/FY 2026 payment determination.
h. PPS-Exempt Cancer Hospital Quality Reporting (PCHQR) Program
    Section 1866(k)(1) of the Act requires, for purposes of FY 2014 and 
each subsequent fiscal year, that a hospital described in section 
1886(d)(1)(B)(v) of the Act (a PPS-exempt cancer hospital, or a PCH) 
submit data in accordance with section 1866(k)(2) of the Act with 
respect to such fiscal year. In the FY 2025 IPPS/LTCH PPS proposed 
rule, we are proposing to adopt the Patient Safety Structural measure 
beginning with the CY 2025 reporting period/FY 2027 program year. We 
are also proposing to modify the HCAHPS Survey measure beginning with 
the CY 2025 reporting period/FY 2027 program year. We are also 
proposing to move up the start date for publicly displaying hospital 
performance on the Hospital Commitment to Health Equity measure from 
July 2026 to January 2026 or as soon as feasible thereafter.
i. Long-Term Care Hospital Quality Reporting Program (LTCH QRP)
    We are proposing the following changes to the LTCH QRP: (1) add 
four items to the LCDS beginning with the FY 2028 LTCH QRP; (2) modify 
one item on the LCDS beginning with the FY 2028 LTCH QRP; and (3) 
extend the admission assessment window for the LCDS beginning with the 
FY 2028 LTCH QRP. We are also seeking information on future measure 
concepts for the

[[Page 35939]]

LTCH QRP and a future LTCH Star Rating system.
j. Medicare Promoting Interoperability Program
    In section X.F. of the preamble of this proposed rule, we are 
proposing several changes to the Medicare Promoting Interoperability 
Program. Specifically, we are proposing: (1) to separate the 
Antimicrobial Use and Resistance (AUR) Surveillance measure into two 
measures, an Antimicrobial Use (AU) Surveillance measure and an 
Antimicrobial Resistance (AR) Surveillance measure, beginning with the 
EHR reporting period in CY 2025; to add a new exclusion for eligible 
hospitals or critical access hospitals (CAHs) that do not have a data 
source containing the minimal discrete data elements that are required 
for AU or AR Surveillance reporting; to modify the applicability of the 
existing exclusions to either the AU or AR Surveillance measures, 
respectively; and to treat the AU and AR Surveillance measures as new 
measures with respect to active engagement beginning with the EHR 
reporting period in CY 2025; (2) to increase the performance-based 
scoring threshold for eligible hospitals and CAHs reporting under the 
Medicare Promoting Interoperability Program from 60 points to 80 points 
beginning with the EHR reporting period in CY 2025; (3) to adopt two 
new eCQMs that hospitals can select as one of their three self-selected 
eCQMs beginning with the CY 2026 reporting period: the Hospital Harm--
Falls with Injury eCQM and the Hospital Harm--Postoperative Respiratory 
Failure eCQM; (4) beginning with the CY 2026 reporting period, to 
modify one eCQM, the Global Malnutrition Composite Score eCQM; and (5) 
to modify eCQM data reporting and submission requirements by proposing 
a progressive increase in the number of mandatory eCQMs eligible 
hospitals and CAHs would be required to report on beginning with the CY 
2026 reporting period.
k. Proposed Distribution of Additional Residency Positions Under the 
Provisions of Section 4122 of Subtitle C of the Consolidated 
Appropriations Act, 2023 (CAA, 2023)
    In this proposed rule, we are including a proposal to implement 
section 4122 of the CAA, 2023. Section 4122(a) of the CAA, 2023, 
amended section 1886(h) of the Act by adding a new section 1886(h)(10) 
of the Act requiring the distribution of additional residency positions 
(also referred to as slots) to hospitals. We refer readers to section 
V.F.2. of the preamble of this proposed rule for a summary of the 
provisions of section 4122 of the CAA, 2023 that we are proposing to 
implement in this proposed rule.
l. Extension of the Medicare-Dependent, Small Rural Hospital (MDH) 
Program and the Temporary Changes to the Low-Volume Hospital Payment 
Adjustment
    The Consolidated Appropriations Act, 2024 (CAA, 2024) (Pub. L. 118-
42), enacted on March 9, 2024, extended the MDH program and the 
temporary changes to the low-volume hospital qualifying criteria and 
payment adjustment under the IPPS for a portion of FY 2025. 
Specifically, section 306 of the CAA, 2024 further extended the 
modified definition of low-volume hospital and the methodology for 
calculating the payment adjustment for low-volume hospitals under 
section 1886(d)(12) of the Act through December 31, 2024. Section 307 
of the CAA, 2024 extended the MDH program under section 1886(d)(5)(G) 
of the Act through December 31, 2024. Prior to enactment of the CAA, 
2024, the low-volume hospital qualifying criteria and payment 
adjustment were set revert to the statutory requirements that were in 
effect prior to FY 2011 at the end of FY 2024 and beginning October 1, 
2024, the MDH program would have no longer been in effect.
    We recognize the importance of these extensions with respect to the 
goal of advancing health equity by addressing the health disparities 
that underlie the health system is one of CMS' strategic pillars \1\ 
and a Biden-Harris Administration priority.\2\ These provisions are 
projected to increase payments to IPPS hospitals by approximately $137 
million in FY 2025.

m. Transforming Episode Accountability Model (TEAM)
    In section X.A. of the preamble of this proposed rule, we propose 
the Transforming Episode Accountability Model (TEAM). TEAM would be a 
5-year mandatory model tested under the authority of section 1115A of 
the Act, beginning on January 1, 2026, and ending on December 31, 2030. 
The intent of TEAM is to improve beneficiary care through financial 
accountability for episodes categories that begin with one of the 
following procedures: coronary artery bypass (CABG), lower extremity 
joint replacement (LEJR), major bowel procedure, surgical hip/femur 
fracture treatment (SHFFT), and spinal fusion. TEAM would test whether 
financial accountability for these episode categories reduces Medicare 
expenditures while preserving or enhancing the quality of care for 
Medicare beneficiaries.
    Under Traditional Medicare, Medicare makes separate payments to 
providers and suppliers for the items and services furnished to a 
beneficiary over the course of an episode of care. Because providers 
and suppliers are paid for each individual item or service delivered, 
providers may not be incentivized to invest in quality improvement and 
care coordination activities. As a result, care may be fragmented, 
unnecessary, or duplicative. By holding hospitals accountable for all 
items and services provided during an episode, providers would be 
better incentivized to coordinate patient care, avoid duplicative or 
unnecessary services, and improve the beneficiary care experience 
during care transitions.
    Under the TEAM proposals, all acute care hospitals, with limited 
exceptions, located within the Core-Based Statistical Areas that CMS 
selects for model implementation would be required to participate in 
TEAM. As proposed, TEAM would have a 1-year glide path opportunity that 
would allow TEAM participants to ease into full financial risk as well 
as different participation tracks to accommodate different levels of 
financial risk and reward. Episodes would include non-excluded Medicare 
Parts A and B items and services and would begin with an anchor 
hospitalization or anchor procedure and would end 30 days after 
hospital discharge. We are proposing that the following episode 
categories, when furnished by a TEAM participant, would initiate a TEAM 
Episode: lower extremity joint replacement, surgical hip femur fracture 
treatment, spinal fusion, coronary artery bypass graft, and major bowel 
procedure.
    TEAM participants would continue to bill Medicare FFS as usual but 
would receive target prices for episodes prior to each performance 
year. Target prices would be based on 3 years of baseline data, 
prospectively trended forward to the relevant performance year, and 
calculated at the level of MS-DRG/HCPCS episode type and region. Target 
prices would also include a discount factor, normalization factor, and 
a risk-adjustment. Performance in the model would be assessed by 
comparing TEAM participants' actual Medicare FFS spending during a 
performance year to their reconciliation target price as well as by 
assessing performance on three quality measures. TEAM participants 
would earn a payment from CMS, subject to a quality performance

[[Page 35940]]

adjustment, if their spending is below the reconciliation target price. 
TEAM participants would owe CMS a repayment amount, subject to a 
quality performance adjustment, if their spending was above the 
reconciliation target price.
n. Maternity Care Request for Information (RFI)
    In alignment with our commitment to addressing the maternal health 
crisis, this RFI seeks to gather information on differences between 
hospital resources required to provide inpatient pregnancy and 
childbirth services to Medicare patients as compared to non-Medicare 
patients. To the extent that the resources required differ between 
patient populations, we also wish to gather information on the extent 
to which non-Medicare payers, or other commercial insurers may be using 
the IPPS as a basis for determining their payment rates for inpatient 
pregnancy and childbirth services and the effect, if any, that the use 
of the IPPS as a basis for determining payment by those payers may have 
on maternal health outcomes.
o. Obstetrical Services RFI
    As a result of ongoing concerns about the provision of maternity 
care in Medicare and Medicaid certified hospitals, CAHS, and REHs, this 
proposed rule includes a request for information regarding our intent 
to propose baseline health and safety standards for obstetrical 
services in future rulemaking. Public comments on the FY 2023 IPPS/LTCH 
PPS proposed rule maternal health request for information recommended 
that CMS explore options to establish an Obstetrical Services condition 
of participation (CoP) for participating hospitals in collaboration 
with relevant stakeholders. With this RFI, we hope to further explore 
such options as we develop a proposal for a targeted Obstetrical 
Services CoP. We are seeking public comment on multiple detailed 
questions, ultimately seeking potential solutions that can be 
implemented through the hospital CoPs to address well-documented 
concerns regarding maternal morbidity, mortality, and access in the 
United States. The goal is to ensure that any policy changes improve 
maternal health care outcomes, addresses unjust disparities in care, 
and do not exacerbate access to care issues.
p. Conditions of Participation Requirements for Hospitals and Critical 
Access Hospitals To Report Acute Respiratory Illnesses
    In section X.F. of the preamble of this proposed rule, we are 
proposing to update the hospital and CAH infection prevention and 
control and antibiotic stewardship programs conditions of participation 
(CoPs) to extend a limited subset of the current COVID-19 and influenza 
data reporting requirements. These proposed reporting requirements 
ensure that hospitals and CAHs have appropriate insight related to 
evolving infection control needs. Specifically, CMS is proposing to 
replace the COVID-19 and Seasonal Influenza reporting standards for 
hospitals and CAHs with a new standard addressing acute respiratory 
illnesses to require that, beginning on October 1, 2024, hospitals and 
CAHs would have to electronically report information about COVID-19, 
influenza, and RSV. CMS is proposing that outside of a public health 
emergency (PHE), hospitals and CAHs would have to report these data on 
a weekly basis.
q. Proposed Changes to the Severity Level Designation for Z Codes 
Describing Inadequate Housing and Housing Instability
    As discussed in section II.C. of the preamble of this proposed 
rule, we are proposing to change the severity level designation for the 
social determinants of health (SDOH) diagnosis codes describing 
inadequate housing and housing instability from non-complication or 
comorbidity (NonCC) to complication or comorbidity (CC) for FY 2025. 
Consistent with our annual updates to account for changes in resource 
consumption, treatment patterns, and the clinical characteristics of 
patients, CMS is recognizing inadequate housing and housing instability 
as indicators of increased resource utilization in the acute inpatient 
hospital setting.
    Consistent with the Administration's goal of advancing health 
equity for all, including members of historically underserved and 
under-resourced communities, as described in the President's January 
20, 2021 Executive Order 13985 on ``Advancing Racial Equity and Support 
for Underserved Communities Through the Federal Government,'' \[1]\ we 
also continue to be interested in receiving feedback on how we might 
further foster the documentation and reporting of the diagnosis codes 
describing social and economic circumstances to more accurately reflect 
each health care encounter and improve the reliability and validity of 
the coded data including in support of efforts to advance health 
equity.

BILLING CODE 4120-01-C

B. Background Summary

1. Acute Care Hospital Inpatient Prospective Payment System (IPPS)
    Section 1886(d) of the Act sets forth a system of payment for the 
operating costs of acute care hospital inpatient stays under Medicare 
Part A (Hospital Insurance) based on prospectively set rates. Section 
1886(g) of the Act requires the Secretary to use a prospective payment 
system (PPS) to pay for the capital-related costs of inpatient hospital 
services for these ``subsection (d) hospitals.'' Under these PPSs, 
Medicare payment for hospital inpatient operating and capital-related 
costs is made at predetermined, specific rates for each hospital 
discharge. Discharges are classified according to a list of diagnosis-
related groups (DRGs).
    The base payment rate is comprised of a standardized amount that is 
divided into a labor-related share and a nonlabor-related share. The 
labor-related share is adjusted by the wage index applicable to the 
area where the hospital is located. If the hospital is located in 
Alaska or Hawaii, the nonlabor-related share is adjusted by a cost-of-
living adjustment factor. This base payment rate is multiplied by the 
DRG relative weight.
    If the hospital treats a high percentage of certain low-income 
patients, it receives a percentage add-on payment applied to the DRG-
adjusted base payment rate. This add-on payment, known as the 
disproportionate share hospital (DSH) adjustment, provides for a 
percentage increase in Medicare payments to hospitals that qualify 
under either of two statutory formulas designed to identify hospitals 
that serve a disproportionate share of low-income patients. For 
qualifying hospitals, the amount of this adjustment varies based on the 
outcome of the statutory calculations. The Affordable Care Act revised 
the Medicare DSH payment methodology and provides for an additional 
Medicare payment beginning on October 1, 2013, that considers the 
amount of uncompensated care furnished by the hospital relative to all 
other qualifying hospitals.
    If the hospital is training residents in an approved residency 
program(s), it receives a percentage add-on payment for each case paid 
under the IPPS, known as the indirect medical education (IME) 
adjustment. This percentage varies, depending on the ratio of residents 
to beds.
    Additional payments may be made for cases that involve new 
technologies or medical services that have been approved for special 
add-on payments. In general, to qualify, a new technology or medical 
service must demonstrate that it is a substantial clinical improvement 
over technologies or services otherwise available, and that, absent an 
add-on payment, it would be inadequately paid under the regular DRG 
payment. In addition, certain transformative new devices and certain 
antimicrobial products may qualify under an alternative inpatient new 
technology add-on payment pathway by demonstrating that, absent an add-
on payment, they would be inadequately paid under the regular DRG 
payment.
    The costs incurred by the hospital for a case are evaluated to 
determine whether the hospital is eligible for an additional payment as 
an outlier case. This additional payment is designed to protect the 
hospital from large financial losses due to unusually expensive cases. 
Any eligible outlier payment is added to the DRG-adjusted base payment 
rate, plus any DSH, IME, and new technology or medical service add-on 
adjustments and, beginning in FY 2023 for IHS and Tribal hospitals and 
hospitals located in Puerto Rico, the new supplemental payment.
    Although payments to most hospitals under the IPPS are made on the 
basis of the standardized amounts, some categories of hospitals are 
paid in whole or in part based on their hospital-specific rate, which 
is determined from their costs in a base year. For example, sole 
community hospitals (SCHs) receive the higher of a hospital-specific 
rate based on their costs in a base year (the highest of FY 1982, FY 
1987, FY 1996, or FY 2006) or the IPPS Federal rate based on the 
standardized amount. SCHs are the sole source of care in their areas. 
Specifically, section 1886(d)(5)(D)(iii) of the Act defines an SCH as a 
hospital that is located more than 35 road miles from another hospital 
or that, by reason of factors such as an isolated location, weather 
conditions, travel conditions, or absence of other like hospitals (as 
determined by the Secretary), is the sole source of hospital inpatient 
services reasonably available to Medicare beneficiaries. In addition, 
certain rural hospitals previously designated by the Secretary as 
essential access community hospitals are considered SCHs.
    With the recent enactment of section 307 of the CAA, 2024, under 
current law, the Medicare-dependent, small rural hospital (MDH) program 
is effective through December 31, 2024. For discharges occurring on or 
after October 1, 2007, but before January 1, 2025, an MDH receives the 
higher of the Federal rate or the Federal rate plus 75 percent of the 
amount by which the Federal rate is exceeded by the highest of its FY 
1982, FY 1987, or FY 2002 hospital-specific rate. MDHs are a major 
source of care for Medicare beneficiaries in their areas. Section 
1886(d)(5)(G)(iv) of the Act defines an MDH as a hospital that is 
located in a rural area (or, as amended by the Bipartisan Budget Act of 
2018, a hospital located in a State with no rural area that meets 
certain statutory criteria), has not more than 100 beds, is not an SCH, 
and has a high percentage of Medicare discharges (not less than 60 
percent of its inpatient days or discharges in its cost reporting year 
beginning in FY 1987 or in two of its three most recently settled 
Medicare cost reporting years). As section 307 of the CAA, 2024 
extended the MDH program through the first quarter of FY 2025 only, 
beginning on January 1, 2025, the MDH program will no longer be in 
effect absent a change in law. Because the MDH program is not 
authorized by statute beyond December 31, 2024, beginning January 1, 
2025, all hospitals that previously qualified for MDH status under 
section 1886(d)(5)(G) of the Act will no longer have MDH status and 
will be paid based on the IPPS Federal rate.
    Section 1886(g) of the Act requires the Secretary to pay for the 
capital-related costs of inpatient hospital services in accordance with 
a prospective payment system established by the Secretary. The basic 
methodology for determining capital prospective payments is set forth 
in our regulations at 42 CFR 412.308 and 412.312. Under the capital 
IPPS, payments are adjusted by the same DRG for the case as they are 
under the operating IPPS. Capital IPPS payments are also adjusted for 
IME and DSH, similar to the adjustments made under the operating IPPS. 
In addition, hospitals may receive outlier payments for those cases 
that have unusually high costs.
    The existing regulations governing payments to hospitals under the 
IPPS are located in 42 CFR part 412, subparts A through M.
2. Hospitals and Hospital Units Excluded From the IPPS
    Under section 1886(d)(1)(B) of the Act, as amended, certain 
hospitals and hospital units are excluded from the IPPS. These 
hospitals and units are: Inpatient rehabilitation facility (IRF) 
hospitals and units; long-term care hospitals (LTCHs); psychiatric 
hospitals and units; children's hospitals; cancer hospitals; extended 
neoplastic disease care hospitals, and hospitals located outside the 50 
States, the District of Columbia, and Puerto Rico (that is, hospitals 
located in the U.S. Virgin

[[Page 35944]]

Islands, Guam, the Northern Mariana Islands, and American Samoa). 
Religious nonmedical health care institutions (RNHCIs) are also 
excluded from the IPPS. Various sections of the Balanced Budget Act of 
1997 (BBA) (Pub. L. 105-33), the Medicare, Medicaid and SCHIP [State 
Children's Health Insurance Program] Balanced Budget Refinement Act of 
1999 (BBRA, Pub. L. 106-113), and the Medicare, Medicaid, and SCHIP 
Benefits Improvement and Protection Act of 2000 (BIPA, Pub. L. 106-554) 
provide for the implementation of PPSs for IRF hospitals and units, 
LTCHs, and psychiatric hospitals and units (referred to as inpatient 
psychiatric facilities (IPFs)). (We note that the annual updates to the 
LTCH PPS are included along with the IPPS annual update in this 
document. Updates to the IRF PPS and IPF PPS are issued as separate 
documents.) Children's hospitals, cancer hospitals, hospitals located 
outside the 50 States, the District of Columbia, and Puerto Rico (that 
is, hospitals located in the U.S. Virgin Islands, Guam, the Northern 
Mariana Islands, and American Samoa), and RNHCIs continue to be paid 
solely under a reasonable cost-based system, subject to a rate-of-
increase ceiling on inpatient operating costs. Similarly, extended 
neoplastic disease care hospitals are paid on a reasonable cost basis, 
subject to a rate-of-increase ceiling on inpatient operating costs.
    The existing regulations governing payments to excluded hospitals 
and hospital units are located in 42 CFR parts 412 and 413.
3. Long-Term Care Hospital Prospective Payment System (LTCH PPS)
    The Medicare prospective payment system (PPS) for LTCHs applies to 
hospitals described in section 1886(d)(1)(B)(iv) of the Act, effective 
for cost reporting periods beginning on or after October 1, 2002. The 
LTCH PPS was established under the authority of sections 123 of the 
BBRA and section 307(b) of the BIPA (as codified under section 
1886(m)(1) of the Act). Section 1206(a) of the Pathway for SGR Reform 
Act of 2013 (Pub. L. 113-67) established the site neutral payment rate 
under the LTCH PPS, which made the LTCH PPS a dual rate payment system 
beginning in FY 2016. Under this statute, effective for LTCH's cost 
reporting periods beginning in FY 2016 cost reporting period, LTCHs are 
generally paid for discharges at the site neutral payment rate unless 
the discharge meets the patient criteria for payment at the LTCH PPS 
standard Federal payment rate. The existing regulations governing 
payment under the LTCH PPS are located in 42 CFR part 412, subpart O. 
Beginning October 1, 2009, we issue the annual updates to the LTCH PPS 
in the same documents that update the IPPS.
4. Critical Access Hospitals (CAHs)
    Under sections 1814(l), 1820, and 1834(g) of the Act, payments made 
to critical access hospitals (CAHs) (that is, rural hospitals or 
facilities that meet certain statutory requirements) for inpatient and 
outpatient services are generally based on 101 percent of reasonable 
cost. Reasonable cost is determined under the provisions of section 
1861(v) of the Act and existing regulations under 42 CFR part 413.
5. Payments for Graduate Medical Education (GME)
    Under section 1886(a)(4) of the Act, costs of approved educational 
activities are excluded from the operating costs of inpatient hospital 
services. Hospitals with approved graduate medical education (GME) 
programs are paid for the direct costs of GME in accordance with 
section 1886(h) of the Act. The amount of payment for direct GME costs 
for a cost reporting period is based on the hospital's number of 
residents in that period and the hospital's costs per resident in a 
base year. The existing regulations governing payments to the various 
types of hospitals are located in 42 CFR part 413. Section 
1886(d)(5)(B) of the Act provides that prospective payment hospitals 
that have residents in an approved GME program receive an additional 
payment for each Medicare discharge to reflect the higher patient care 
costs of teaching hospitals relative to non-teaching hospitals. The 
additional payment is based on the indirect medical education (IME) 
adjustment factor, which is calculated using a hospital's ratio of 
residents to beds and a multiplier, which is set by Congress. Section 
1886(d)(5)(B)(ii)(XII) of the Act provides that, for discharges 
occurring during FY 2008 and fiscal years thereafter, the IME formula 
multiplier is 1.35. The regulations regarding the indirect medical 
education (IME) adjustment are located at 42 CFR 412.105.

C. Summary of Provisions of Recent Legislation That Would Be 
Implemented in This Proposed Rule

1. The Consolidated Appropriations Act, 2023 (CAA 2023; Pub. L. 117-
328)
    Section 4122 of the CAA, 2023, amended section 1886(h) of the Act 
by adding a new section 1886(h)(10) of the Act requiring the 
distribution of additional residency positions (also referred to as 
slots) to hospitals. Section 1886(h)(10)(A) of the Act requires that 
for FY 2026, the Secretary shall initiate an application round to 
distribute 200 residency positions. At least 100 of the positions made 
available under section 1886(h)(10)(A) of the Act shall be distributed 
for psychiatry or psychiatry subspecialty residency training programs. 
The Secretary is required, subject to certain provisions in the law, to 
increase the otherwise applicable resident limit for each qualifying 
hospital that submits a timely application by the number of positions 
that may be approved by the Secretary for that hospital. The Secretary 
is required to notify hospitals of the number of positions distributed 
to them by January 31, 2026, and the increase is effective beginning 
July 1, 2026.
    In determining the qualifying hospitals for which an increase is 
provided, section 1886(h)(10)(B)(i) of the Act requires the Secretary 
to take into account the ``demonstrated likelihood'' of the hospital 
filling the positions made available within the first 5 training years 
beginning after the date the increase would be effective, as determined 
by the Secretary.
    Section 1886(h)(10)(B)(ii) of the Act requires a minimum 
distribution for certain categories of hospitals. Specifically, the 
Secretary is required to distribute at least 10 percent of the 
aggregate number of total residency positions available to each of four 
categories of hospitals. Stated briefly, and discussed in greater 
detail later in this proposed rule, the categories are as follows: (1) 
hospitals located in rural areas or that are treated as being located 
in a rural area (pursuant to sections 1886(d)(2)(D) and 1886(d)(8)(E) 
of the Act); (2) hospitals in which the reference resident level of the 
hospital is greater than the otherwise applicable resident limit; (3) 
hospitals in States with new medical schools or additional locations 
and branches of existing medical schools; and (4) hospitals that serve 
areas designated as Health Professional Shortage Areas (HPSAs). Section 
1886(h)(10)(F)(iii) of the Act defines a qualifying hospital as a 
hospital in one of these four categories.
    Section 1886(h)(10)(B)(iii) of the Act further requires that each 
qualifying hospital that submits a timely application receive at least 
1 (or a fraction of 1) of the residency positions made available under 
section 1886(h)(10) of the Act before any qualifying hospital receives 
more than 1 residency position.
    Section 1886(h)(10)(C) of the Act places certain limitations on the 
distribution of the residency positions.

[[Page 35945]]

First, a hospital may not receive more than 10 additional full-time 
equivalent (FTE) residency positions. Second, no increase in the 
otherwise applicable resident limit of a hospital may be made unless 
the hospital agrees to increase the total number of FTE residency 
positions under the approved medical residency training program of the 
hospital by the number of positions made available to that hospital. 
Third, if a hospital that receives an increase to its otherwise 
applicable resident limit under section 1886(h)(10) of the Act is 
eligible for an increase to its otherwise applicable resident limit 
under 42 CFR 413.79(e)(3) (or any successor regulation), that hospital 
must ensure that residency positions received under section 1886(h)(10) 
of the Act are used to expand an existing residency training program 
and not for participation in a new residency training program.
2. The Consolidated Appropriations Act, 2024 (CAA, 2024; Pub. L. 118-
42)
    Section 306 of the CAA, 2024 extended through the first 3 months of 
FY 2025 the modified definition of a low-volume hospital and the 
methodology for calculating the payment adjustment for low-volume 
hospitals in effect for FYs 2019 through 2024. Specifically, under 
section 1886(d)(12)(C)(i) of the Act, as amended, for FYs 2019 through 
2024 and the portion of FY 2025 occurring before January 1, 2025, a 
subsection (d) hospital qualifies as a low-volume hospital if it is 
more than 15 road miles from another subsection (d) hospital and has 
less than 3,800 total discharges during the fiscal year. Under section 
1886(d)(12)(D) of the Act, as amended, for discharges occurring in FYs 
2019 through December 31, 2024, the Secretary determines the applicable 
percentage increase using a continuous, linear sliding scale ranging 
from an additional 25 percent payment adjustment for low-volume 
hospitals with 500 or fewer discharges to a zero percent additional 
payment for low-volume hospitals with more than 3,800 discharges in the 
fiscal year.
    Section 307 of the CAA, 2024 amended sections 1886(d)(5)(G)(i) and 
1886(d)(5)(G)(ii)(II) of the Act to provide for an extension of the MDH 
program through the first 3 months of FY 2025 (that is, through 
December 31, 2024).

D. Summary of the Proposed Provisions

    In this proposed rule, we set forth proposed payment and policy 
changes to the Medicare IPPS for FY 2025 operating costs and capital-
related costs of acute care hospitals and certain hospitals and 
hospital units that are excluded from IPPS. In addition, we set forth 
proposed changes to the payment rates, factors, and other payment and 
policy-related changes to programs associated with payment rate 
policies under the LTCH PPS for FY 2025.
    The following is a general summary of the changes that we are 
proposing to make in this proposed rule.

technologies approved for add-on payments for FY 2024, a presentation 
of our evaluation and analysis of the FY 2025 applicants for add-on 
payments for high-cost new medical services and technologies (including 
public input, as directed by the Medicare Prescription Drug, 
Improvement, and Modernization Act of 2003 (MMA) Pub. L. 108-173, 
obtained in a town hall meeting for applications not submitted under an 
alternative pathway), and a discussion of the proposed status of FY 
2025 new technology applicants under the alternative pathways for 
certain medical devices and certain antimicrobial products.
     A proposal to change the April 1 cutoff to October 1 for 
determining whether a technology would be within its 2- to 3-year 
newness period when considering eligibility for new technology add-on 
payments, beginning in FY 2026, effective for those technologies that 
are approved for new technology add-on payments starting in FY 2025 or 
a subsequent years (as discussed in II.E.7. of the preamble of this 
proposed rule).
     A proposal that, beginning with new technology add-on 
payment applications for FY 2026, we will no longer consider a hold 
status to be an inactive status for the purposes of eligibility for the 
new technology add-on payment (as discussed in section II.E.8. of the 
preamble of this proposed rule).
     A proposal that, subject to our review of the new 
technology add-on payment eligibility criteria, for certain gene 
therapies approved for new technology add-on payments in the FY 2025 
IPPS/LTCH final rule for the treatment of sickle cell disease (SCD), 
effective with discharges on or after October 1, 2024, and concluding 
at the end of the 2- to 3-year newness period for such therapy, we will 
temporarily increase the new technology add-on payment percentage to 75 
percent (as discussed in section II.E.9. of the preamble of this 
proposed rule).
2. Proposed Changes to the Hospital Wage Index for Acute Care Hospitals
    In section III. of the preamble of this proposed rule, we propose 
revisions to the wage index for acute care hospitals and the annual

hospitals, based on hospital redesignations and reclassifications under 
sections 1886(d)(8)(B), (d)(8)(E), and (d)(10) of the Act.
     Proposed adjustment to the wage index for acute care 
hospitals for FY 2025 based on commuting patterns of hospital employees 
who reside in a county and work in a different area with a higher wage 
index.
     Proposed labor-related share for the FY 2025 wage index.
3. Payment Adjustment for Medicare Disproportionate Share Hospitals 
(DSHs) for FY 2025
    In section IV. of the preamble of this proposed rule, we discuss 
the following:
     Proposed calculation of Factor 1 and Factor 2 of the 
uncompensated care payment methodology.
     Proposed methodological approach for determining Factor 3 
of the uncompensated care payment for FY 2025, which is the same 
methodology that was used for FY 2024.
     Proposed methodological approach for determining the 
amount of interim uncompensated care payments using the average of the 
most recent 3 years of discharge data.

[[Page 35946]]

4. Other Decisions and Proposed Changes to the IPPS for Operating Costs

to rebase and revise the LTCH market basket to reflect a 2022 base 
year, which includes a proposed update to the LTCH PPS labor-related 
share. In section VIII. of the preamble of the proposed rule, we set 
forth proposed changes to the LTCH PPS Federal payment rates, factors, 
and other payment rate policies under the LTCH PPS for FY 2025. We are 
also proposing a technical clarification to the regulations for 
hospitals seeking to be classified as an LTCH.
8. Proposed Changes Relating to Quality Data Reporting for Specific 
Providers and Suppliers
    In section IX. of the preamble of the proposed rule, we addressed 
the following:
     Solicitation of comment on adopting measures across the 
hospital quality reporting and value-based purchasing programs which 
capture more forms of unplanned post-acute care and encourage hospitals 
to improve discharge processes.
     Proposed changes to the requirements for the Hospital IQR 
Program.
     Proposed changes to the requirements for the PCHQR 
Program.
     Proposed adoption of the Patient Safety Structural measure 
in the Hospital IQR Program and the PCHQR Program.
     Proposed updated HCAHPS Survey measure in the Hospital IQR 
Program, PCHQR Program, and Hospital VBP Program.
     Proposed changes to the requirements for the Long-Term 
Care Hospital Quality Reporting Program (LTCH QRP), and request for 
information on future measure concepts for the LTCH QRP and a star 
rating system for the LTCH QRP.
     Proposed changes to requirements pertaining to eligible 
hospitals and CAHs participating in the Medicare Promoting 
Interoperability Program.
9. Other Proposals and Comment Solicitations Included in the Proposed 
Rule
    Section X. of the preamble of the proposed rule includes the 
following:
     Proposed implementation of TEAM that would test whether an 
episode-based pricing methodology linked with accountability for 
quality measure performance for select acute care hospitals reduces 
Medicare program expenditures while preserving or improving the quality 
of care for Medicare beneficiaries.
     Proposed changes to permit a Provider Reimbursement Review 
Board (PRRB) member to serve up to 3 consecutive terms (9 consecutive 
years total), and up to 4 consecutive terms (12 consecutive years 
total) in cases where a PRRB Member who, in their second or third 
consecutive term, is designated as Chairperson, to continue serving as 
Chairperson in the fourth consecutive term.
     Solicitation of comments to gather information on 
differences between hospital resources required to provide inpatient 
pregnancy and childbirth services to Medicare patients as compared to 
non-Medicare patients.
     Solicitation of comments to gather information on 
potential solutions that can be implemented through the hospital CoPs 
to address well-documented concerns regarding maternal morbidity, 
mortality, disparities, and maternity care access in the United States.
     Proposal to remove the exclusion of Puerto Rico from the 
Payment Error Rate Measurement (PERM) program found at 42 CFR

     Proposal for a new hospital CoP to replace the COVID-19 
and Seasonal Influenza reporting standards for hospitals and CAHs that 
were created during PHE.
10. Other Provisions of the Proposed Rule
    Section XI.A. of the preamble of the proposed rule includes our 
discussion of the MedPAC Recommendations.

[[Page 35947]]

    Section XI.B. of the preamble of the proposed rule includes a 
descriptive listing of the public use files associated with this 
proposed rule.
    Section XII. of the preamble of the proposed rule includes the 
collection of information requirements for entities based on our 
proposals.
    Section XIII. of the preamble of the proposed rule includes 
information regarding our responses to public comments.
11. Determining Prospective Payment Operating and Capital Rates and 
Rate-of-Increase Limits for Acute Care Hospitals
    In sections II. and III. of the Addendum of the proposed rule, we 
set forth proposed changes to the amounts and factors for determining 
the proposed FY 2025 prospective payment rates for operating costs and 
capital-related costs for acute care hospitals. We are proposing to 
establish the threshold amounts for outlier cases. In addition, in 
section IV. of the Addendum of the proposed rule, we address the 
proposed update factors for determining the rate-of-increase limits for 
cost reporting periods beginning in FY 2025 for certain hospitals 
excluded from the IPPS.
12. Determining Prospective Payment Rates for LTCHs
    In section V. of the Addendum of the proposed rule, we set forth 
proposed changes to the amounts and factors for determining the 
proposed FY 2025 LTCH PPS standard Federal payment rate and other 
factors used to determine LTCH PPS payments under both the LTCH PPS 
standard Federal payment rate and the site neutral payment rate in FY 
2025. We are proposing to establish the adjustments for the wage index 
(including proposed changes to the LTCH PPS labor market area 
delineations based on the new OMB delineations), labor-related share, 
the cost-of-living adjustment, and high-cost outliers, including the 
applicable fixed-loss amounts and the LTCH cost-to-charge ratios (CCRs) 
for both payment rates.
13. Impact Analysis
    In Appendix A of the proposed rule, we set forth an analysis of the 
impact the proposed changes would have on affected acute care 
hospitals, CAHs, LTCHs and other entities.
14. Recommendation of Update Factors for Operating Cost Rates of 
Payment for Hospital Inpatient Services
    In Appendix B of the proposed rule, as required by sections 
1886(e)(4) and (e)(5) of the Act, we provide our recommendations of the 
appropriate percentage changes for FY 2025 for the following:
     A single average standardized amount for all areas for 
hospital inpatient services paid under the IPPS for operating costs of 
acute care hospitals (and hospital-specific rates applicable to SCHs 
and MDHs).
     Target rate-of-increase limits to the allowable operating 
costs of hospital inpatient services furnished by certain hospitals 
excluded from the IPPS.
     The LTCH PPS standard Federal payment rate and the site 
neutral payment rate for hospital inpatient services provided for LTCH 
PPS discharges.
15. Discussion of Medicare Payment Advisory Commission Recommendations
    Under section 1805(b) of the Act, MedPAC is required to submit a 
report to Congress, no later than March 15 of each year, in which 
MedPAC reviews and makes recommendations on Medicare payment policies. 
MedPAC's March 2024 recommendations concerning hospital inpatient 
payment policies address the update factor for hospital inpatient 
operating costs and capital-related costs for hospitals under the IPPS. 
We address these recommendations in Appendix B of the proposed rule. 
For further information relating specifically to the MedPAC March 2024 
report or to obtain a copy of the report, contact MedPAC at (202) 220-
3700 or visit MedPAC's website at https://www.medpac.gov.

II. Proposed Changes to Medicare Severity Diagnosis-Related Group (MS-
DRG) Classifications and Relative Weights

A. Background

    Section 1886(d) of the Act specifies that the Secretary shall 
establish a classification system (referred to as diagnosis-related 
groups (DRGs)) for inpatient discharges and adjust payments under the 
IPPS based on appropriate weighting factors assigned to each DRG. 
Therefore, under the IPPS, Medicare pays for inpatient hospital 
services on a rate per discharge basis that varies according to the DRG 
to which a beneficiary's stay is assigned. The formula used to 
calculate payment for a specific case multiplies an individual 
hospital's payment rate per case by the weight of the DRG to which the 
case is assigned. Each DRG weight represents the average resources 
required to care for cases in that particular DRG, relative to the 
average resources used to treat cases in all DRGs.
    Section 1886(d)(4)(C) of the Act requires that the Secretary adjust 
the DRG classifications and relative weights at least annually to 
account for changes in resource consumption. These adjustments are made 
to reflect changes in treatment patterns, technology, and any other 
factors that may change the relative use of hospital resources.

B. Adoption of the MS-DRGs and MS-DRG Reclassifications

    For information on the adoption of the MS-DRGs in FY 2008, we refer 
readers to the FY 2008 IPPS final rule with comment period (72 FR 47140 
through 47189).
    For general information about the MS-DRG system, including yearly 
reviews and changes to the MS-DRGs, we refer readers to the previous 
discussions in the FY 2010 IPPS/RY 2010 LTCH PPS final rule (74 FR 
43764 through 43766) and the FYs 2011 through 2024 IPPS/LTCH PPS final 
rules (75 FR 50053 through 50055; 76 FR 51485 through 51487; 77 FR 
53273; 78 FR 50512; 79 FR 49871; 80 FR 49342; 81 FR 56787 through 
56872; 82 FR 38010 through 38085; 83 FR 41158 through 41258; 84 FR 
42058 through 42165; 85 FR 58445 through 58596; 86 FR 44795 through 
44961; 87 FR 48800 through 48891; and 88 FR 58654 through 58787, 
respectively).
    For discussion regarding our previously finalized policies 
(including our historical adjustments to the payment rates) relating to 
the effect of changes in documentation and coding that do not reflect 
real changes in case mix, we refer readers to the FY 2023 IPPS/LTCH PPS 
final rule (87 FR 48799 through 48800).

C. Proposed Changes to Specific MS-DRG Classifications

1. Discussion of Changes to Coding System and Basis for Proposed FY 
2025 MS-DRG Updates
a. Conversion of MS-DRGs to the International Classification of 
Diseases, 10th Revision (ICD-10)
    As of October 1, 2015, providers use the International 
Classification of Diseases, 10th Revision (ICD-10) coding system to 
report diagnoses and procedures for Medicare hospital inpatient 
services under the MS-DRG system instead of the ICD-9-CM coding system, 
which was used through September 30, 2015. The ICD-10 coding system 
includes the International Classification of Diseases, 10th Revision, 
Clinical Modification (ICD-10-CM) for diagnosis coding and the 
International Classification of Diseases, 10th Revision, Procedure 
Coding

[[Page 35948]]

System (ICD-10-PCS) for inpatient hospital procedure coding, as well as 
the ICD-10-CM and ICD-10-PCS Official Guidelines for Coding and 
Reporting. For a detailed discussion of the conversion of the MS-DRGs 
to ICD-10, we refer readers to the FY 2017 IPPS/LTCH PPS final rule (81 
FR 56787 through 56789).
b. Basis for Proposed FY 2025 MS-DRG Updates
    As discussed in the FY 2023 IPPS/LTCH PPS proposed rule (87 FR 
28127) and final rule (87 FR 48800 through 48801), beginning with FY 
2024 MS-DRG classification change requests, we changed the deadline to 
request changes to the MS-DRGs to October 20 of each year to allow for 
additional time for the review and consideration of any proposed 
updates. We also described the new process for submitting requested 
changes to the MS-DRGs via a new electronic application intake system, 
Medicare Electronic Application Request Information SystemTM 
(MEARISTM), accessed at https://mearis.cms.gov. We stated 
that effective with FY 2024 MS-DRG classification change requests, CMS 
will only accept requests submitted via MEARISTM and will no 
longer consider requests sent via email. Additionally, we noted that 
within MEARISTM, we have built in several resources to 
support users, including a ``Resources'' section available at https://mearis.cms.gov/public/resources with technical support available under 
``Useful Links'' at the bottom of the MEARISTM site. 
Questions regarding the MEARISTM system can be submitted to 
CMS using the form available under ``Contact'', also at the bottom of 
the MEARISTM site. Accordingly, interested parties had to 
submit MS-DRG classification change requests for FY 2025 by October 20, 
2023.
    We note that the burden associated with this information collection 
requirement is the time and effort required to collect and submit the 
data in the request for MS-DRG classification changes to CMS. The 
aforementioned burden is subject to the Paperwork Reduction Act (PRA) 
of 1995 and approved under OMB control number 0938-1431 and has an 
expiration date of 09/30/2025.
    Interested parties should submit any MS-DRG classification change 
requests, including any comments and suggestions for FY 2026 
consideration by October 20, 2024 via MEARISTM at: https://mearis.cms.gov/public/home.
    As we have discussed in prior rulemaking, we may not be able to 
fully consider all of the requests that we receive for the upcoming 
fiscal year. We have found that, with the implementation of ICD-10, 
some types of requested changes to the MS-DRG classifications require 
more extensive research to identify and analyze all of the data that 
are relevant to evaluating the potential change. We note in the 
discussion that follows those topics for which further research and 
analysis are required, and which we will continue to consider in 
connection with future rulemaking.
    We received four requests to modify the GROUPER logic in a number 
of cardiac MS-DRGs under Major Diagnostic Category (MDC) 05 (Diseases 
and Disorders of the Circulatory System). Specifically, we received 
requests to--
     Modify the GROUPER logic of new MS-DRG 212 (Concomitant 
Aortic and Mitral Valve Procedures) to be defined by cases reporting 
procedure codes describing a single open mitral or aortic valve 
replacement/repair (MVR or AVR) procedure, plus an open coronary artery 
bypass graft procedure (CABG) or open surgical ablation or cardiac 
catheterization procedure plus a second concomitant procedure.
     Modify the GROUPER logic of new MS-DRG 212 by redefining 
the procedure code list that describes the performance of a cardiac 
catheterization by either removing the ICD-10-PCS codes that describe 
plain radiography of coronary artery codes from the logic list or 
adding ICD-10-PCS procedure codes that involve computed tomography (CT) 
or magnetic resonance imaging (MRI) scanning using contrast to the 
list. This requestor also suggested that CMS add ICD-10-PCS procedures 
codes that describe endovascular valve replacement or repair procedures 
into the GROUPER logic of MS-DRG 212.
     Modify the GROUPER logic of new MS-DRGs 323, 324 and 325 
(Coronary Intravascular Lithotripsy with Intraluminal Device with MCC, 
without MCC, and without Intraluminal Device, respectively). In two 
separate but related requests, the requestors suggested that we add 
procedure codes that describe additional percutaneous coronary 
intervention (PCI) procedures such as percutaneous coronary rotational, 
laser, and orbital atherectomy to the GROUPER logic of new MS-DRGs 323, 
324, and 325.
    We appreciate the submissions and related analyses provided by the 
requestors for our consideration as we review MS-DRG classification 
change requests for FY 2025; however, we note the complexity of the 
GROUPER logic for these MS-DRGs in connection with these requests 
requires more extensive analyses to identify and evaluate all of the 
data relevant to assessing these potential modifications. Specifically, 
we note the list of procedure codes that describe the performance of a 
cardiac catheterization is in the definition of multiple MS-DRGs in MDC 
05. Analyzing the impact of revising this list necessitates evaluating 
the impact across numerous other MS-DRGs in MDC 05 that also include 
this list in their definition, in addition to new MS-DRG 212. Secondly, 
as discussed further in section II.C.4.c of this proposed rule, our 
analysis continues to indicate that, when performed, open cardiac valve 
replacement and supplement procedures are clinically different from 
endovascular cardiac valve replacement and supplement procedures in 
terms of technical complexity and hospital resource use. Lastly, as we 
have stated in prior rule making (88 FR 58708), atherectomy is distinct 
from coronary lithotripsy in that each of these procedures are defined 
by clinically distinct definitions and objectives. Additional analysis 
to assess for unintended consequences across the classification is 
needed as we have made a distinction between the root operations used 
to describe atherectomy (Extirpation) and the root operation used to 
describe lithotripsy (Fragmentation) in evaluating other requests in 
rulemaking. We will need to consider the application of these two root 
operations in other scenarios where we have also specifically stated 
that Extirpation is not the same as Fragmentation and do not warrant 
similar MS-DRG assignment (85 FR 58572 through 58573). Furthermore, as 
MS-DRG 212 and MS-DRGs 323, 324 and 325 recently became effective on 
October 1, 2023 (FY 2024), we believe additional time is needed to 
review and evaluate extensive modifications to the structure of these 
MS-DRGs.
    We will continue to monitor the data as we consider these issues in 
connection with future rulemaking. As we continue the analysis of the 
claims data with respect to MS-DRGs in MDC 05, we welcome public 
comments and feedback on other factors that should be considered in the 
potential restructuring of these MS-DRGs. Feedback and other 
suggestions may be directed to MEARISTM at: https://mearis.cms.gov/public/home. As noted, interested parties should submit 
any MS-DRG classification change requests, including any comments and 
suggestions for FY 2026 consideration by October 20, 2024 via 
MEARISTM at: https://mearis.cms.gov/public/home.
    As we did for the FY 2024 IPPS/LTCH PPS proposed rule, for this FY 
2025

[[Page 35949]]

IPPS/LTCH PPS proposed rule we are providing a test version of the ICD-
10 MS-DRG GROUPER Software, Version 42, so that the public can better 
analyze and understand the impact of the proposals included in this 
proposed rule. We note that this test software reflects the proposed 
GROUPER logic for FY 2025. Therefore, it includes the new diagnosis and 
procedure codes that are effective for FY 2025 as reflected in Table 
6A.--New Diagnosis Codes--FY 2025 and Table 6B.--New Procedure Codes--
FY 2025 associated with this proposed rule and does not include the 
diagnosis codes that are invalid beginning in FY 2025 as reflected in 
Table 6C.--Invalid Diagnosis Codes--FY 2025, and Table 6D.--Invalid 
Procedure Codes--FY 2025 associated with this proposed rule. These 
tables are not published in the Addendum to this proposed rule, but are 
available on the CMS website at: https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/index.html as described in 
section VI. of the Addendum to this proposed rule. Because the 
diagnosis codes no longer valid for FY 2025 are not reflected in the 
test software, we are making available a supplemental file in Table 
6P.1a and 6P.1b that includes the mapped Version 42 FY 2025 ICD-10-CM 
and ICD-10-PCS codes and the deleted Version 41 FY 2024 ICD-10-CM codes 
and V41.1 ICD-10-PCS codes that should be used for testing purposes 
with users' available claims data. Therefore, users will have access to 
the test software allowing them to build case examples that reflect the 
proposals included in this proposed rule. In addition, users will be 
able to view the draft version of the ICD-10 MS-DRG Definitions Manual, 
Version 42.
    We also note that in the FY 2024 IPPS/LTCH PPS final rule (88 FR 
58764), we stated that, as discussed in the CY 2024 Outpatient 
Prospective Payment System and Ambulatory Surgical Center (OPPS/ASC) 
proposed rule (CY 2024 OPPS/ASC proposed rule) (88 FR 49552, July 31, 
2023), consistent with the process that is used for updates to the 
``Integrated'' Outpatient Code Editor (I/OCE) and other Medicare claims 
editing systems, we proposed to address any future revisions to the 
IPPS Medicare Code Editor (MCE), including any additions or deletions 
of claims edits, as well as the addition or deletion of ICD-10 
diagnosis and procedure codes to the applicable MCE edit code lists, 
outside of the annual IPPS rulemakings. As discussed in the CY 2024 
OPPS/ASC proposed rule, we proposed to remove discussion of the IPPS 
MCE from the annual IPPS rulemakings, beginning with the FY 2025 
rulemaking, and to generally address future changes or updates to the 
MCE through instruction to the Medicare administrative contractors 
(MACs). We encouraged readers to review the discussion in the CY 2024 
OPPS/ASC proposed rule and submit comments in response to the proposal 
by the applicable deadline by following the instructions provided in 
that proposed rule.
    In the CY 2024 OPPS/ASC final rule (88 FR 82121 through 82124), 
after consideration of the public comments we received, we finalized 
the proposal to remove discussion of the MCE from the annual IPPS 
rulemakings, beginning with FY 2025 rulemaking, and to generally 
address future changes or updates to the MCE through instruction to the 
MACs. Beginning with FY 2025, in association with the annual proposed 
rule, we are making available a draft version of the Definitions of 
Medicare Code Edits (MCE) Manual to provide the public with an 
opportunity to review any changes that will become effective October 1 
for the upcoming fiscal year. In addition, as a result of new and 
modified code updates approved after the annual spring ICD-10 
Coordination and Maintenance Committee meeting, any further changes to 
the MCE will be reflected in the finalized Definitions of Medicare Code 
Edits (MCE) Manual, made available in association with the annual final 
rule. We are making available the draft FY 2025 ICD-10 MCE Version 42 
Manual file on the CMS website at: https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps/ms-drg-classifications-and-software.
    The MCE manual is comprised of two chapters: Chapter 1: Edit code 
lists provides a listing of each edit, an explanation of each edit, and 
as applicable, the diagnosis and/or procedure codes for each edit, and 
Chapter 2: Code list changes summarizes the changes in the edit code 
lists (for example, additions and deletions) from the prior release of 
the MCE software. The public may submit any questions, comments, 
concerns, or recommendations regarding the MCE to the CMS mailbox at 
[email protected] for our review and consideration.
    The test version of the ICD-10 MS-DRG GROUPER Software, Version 42, 
the draft version of the ICD-10 MS-DRG Definitions Manual, Version 42, 
the draft version of the Definitions of Medicare Code Edits Manual, 
Version 42, and the supplemental mapping files in Table 6P.1a and 6P.1b 
of the FY 2024 and FY 2025 ICD-10-CM diagnosis and ICD-10-PCS procedure 
codes are available at https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/MS-DRG-Classifications-and-Software.
    Following are the changes that we are proposing to the MS-DRGs for 
FY 2025. We are inviting public comments on each of the MS-DRG 
classification proposed changes, as well as our proposals to maintain 
certain existing MS-DRG classifications discussed in this proposed 
rule. In some cases, we are proposing changes to the MS-DRG 
classifications based on our analysis of claims data and clinical 
appropriateness. In other cases, we are proposing to maintain the 
existing MS-DRG classifications based on our analysis of claims data 
and clinical appropriateness. For this FY 2025 IPPS/LTCH PPS proposed 
rule, our MS-DRG analysis was based on ICD-10 claims data from the 
September 2023 update of the FY 2023 MedPAR file, which contains 
hospital bills received from October 1, 2022 through September 30, 
2023. In our discussion of the proposed MS-DRG reclassification 
changes, we refer to these claims data as the ``September 2023 update 
of the FY 2023 MedPAR file.''
    In deciding whether to propose to make further modifications to the 
MS-DRGs for particular circumstances brought to our attention, we 
consider whether the resource consumption and clinical characteristics 
of the patients with a given set of conditions are significantly 
different than the remaining patients represented in the MS-DRG. We 
evaluate patient care costs using average costs and lengths of stay and 
rely on clinical factors to determine whether patients are clinically 
distinct or similar to other patients represented in the MS-DRG. In 
evaluating resource costs, we consider both the absolute and percentage 
differences in average costs between the cases we select for review and 
the remainder of cases in the MS-DRG. We also consider variation in 
costs within these groups; that is, whether observed average 
differences are consistent across patients or attributable to cases 
that are extreme in terms of costs or length of stay, or both. Further, 
we consider the number of patients who will have a given set of 
characteristics and generally prefer not to create a new MS-DRG unless 
it would include a substantial number of cases.
    In the FY 2021 IPPS/LTCH PPS final rule (85 FR 58448), we finalized 
our proposal to expand our existing criteria to create a new 
complication or comorbidity (CC) or major complication

[[Page 35950]]

or comorbidity (MCC) subgroup within a base MS-DRG. Specifically, we 
finalized the expansion of the criteria to include the NonCC subgroup 
for a three-way severity level split. We stated we believed that 
applying these criteria to the NonCC subgroup would better reflect 
resource stratification as well as promote stability in the relative 
weights by avoiding low volume counts for the NonCC level MS-DRGs. We 
noted that in our analysis of MS-DRG classification requests for FY 
2021 that were received by November 1, 2019, as well as any additional 
analyses that were conducted in connection with those requests, we 
applied these criteria to each of the MCC, CC, and NonCC subgroups. We 
also noted that the application of the NonCC subgroup criteria going 
forward may result in modifications to certain MS-DRGs that are 
currently split into three severity levels and result in MS-DRGs that 
are split into two severity levels. We stated that any proposed 
modifications to the MS-DRGs would be addressed in future rulemaking 
consistent with our annual process and reflected in Table 5--Proposed 
List of Medicare Severity Diagnosis Related Groups (MS-DRGs), Relative 
Weighting Factors, and Geometric and Arithmetic Mean Length of Stay for 
the applicable fiscal year.
    In the FY 2022 IPPS/LTCH PPS final rule (86 FR 44798), we finalized 
a delay in applying this technical criterion to existing MS-DRGs until 
FY 2023 or future rulemaking, in light of the public health emergency 
(PHE). Interested parties recommended that a complete analysis of the 
MS-DRG changes to be proposed for future rulemaking in connection with 
the expanded three-way severity split criteria be conducted and made 
available to enable the public an opportunity to review and consider 
the redistribution of cases, the impact to the relative weights, 
payment rates, and hospital case mix to allow meaningful comment prior 
to implementation.
    In the FY 2023 IPPS/LTCH PPS final rule (87 FR 48803), we also 
finalized a delay in application of the NonCC subgroup criteria to 
existing MS-DRGs with a three-way severity level split in light of the 
ongoing PHE and until such time additional analyses can be performed to 
assess impacts, as discussed in response to public comments in the FY 
2022 and FY 2023 IPPS/LTCH PPS final rules.
    In association with our discussion of application of the NonCC 
subgroup criteria in the FY 2024 IPPS/LTCH PPS proposed rule (88 FR 
26673 through 26676), we provided an alternate test version of the ICD-
10 MS-DRG GROUPER Software, Version 41.A, reflecting the proposed 
GROUPER logic for FY 2024 as modified by the application of the NonCC 
subgroup criteria to existing MS-DRGs with a three-way severity level 
split, available at https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/MS-DRG-Classifications-and-Software. 
Therefore, users had access to the alternate test software allowing 
them to build case examples that reflect the proposals included in the 
proposed rule with application of the NonCC subgroup criteria. We also 
provided additional files including an alternate Table 5--Alternate 
List of Medicare Severity Diagnosis Related Groups (MS-DRGs), Relative 
Weighting Factors, and Geometric and Arithmetic Mean Length of Stay, an 
alternate Length of Stay (LOS) Statistics file, an alternate Case Mix 
Index (CMI) file, and an alternate After Outliers Removed and Before 
Outliers Removed (AOR_BOR) file. The files are available in association 
with the FY 2024 IPPS/LTCH PPS proposed rule on the CMS website at: 
https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps.
    We stated that the alternate test software and additional files 
were made available so that the public could better analyze and 
understand the impact on the proposals included in the proposed rule if 
the NonCC subgroup criteria were to be applied to existing MS-DRGs with 
a three-way severity level split. We refer readers to the FY 2024 IPPS/
LTCH PPS proposed rule (88 FR 26673 through 26676) for further 
discussion of the alternate test software and additional files that 
were made available.
    In the FY 2024 IPPS/LTCH PPS final rule (88 FR 58655 through 
58661), we finalized to delay the application of the NonCC subgroup 
criteria to existing MS-DRGs with a three-way severity level split for 
FY 2024. We stated that we would continue to review and consider the 
feedback we had received in response to the additional information we 
made available in association with the FY 2024 IPPS/LTCH PPS proposed 
rule for our development of the FY 2025 proposed rule.
    We note that the IPPS Payment Impact File made available in 
connection with our annual IPPS rulemakings includes information used 
to categorize hospitals by various geographic and special payment 
consideration groups, including geographic location (urban or rural), 
teaching hospital status (that is, whether or not a hospital has GME 
residency programs and receives an IME adjustment), DSH hospital status 
(that is, whether or not a hospital receives Medicare DSH payments), 
special payment groups (that is, SCHs, MDHs, and RRCs) and other 
categories reflected in the impact analysis generally shown in Appendix 
A of the annual IPPS rulemakings. The IPPS Payment Impact File 
associated with the FY 2024 IPPS/LTCH PPS final rule can be found on 
the CMS website at: https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps/fy-2024-ipps-final-rule-home-page#Data.
    We are proposing to continue to delay application of the NonCC 
subgroup criteria to existing MS-DRGs with a three-way severity level 
split for FY 2025, as we continue to consider the public comments 
received in response to the FY 2024 rulemaking. We encourage interested 
parties to review the impacts and other information made available with 
the alternate test software (V41.A) and other additional files provided 
in connection with the FY 2024 IPPS/LTCH PPS proposed rule, as 
previously discussed, and we continue to welcome feedback for 
consideration for future rulemaking.
    As discussed in the FY 2024 IPPS/LTCH PPS final rule (88 FR 58661), 
we continue to apply the criteria to create subgroups, including 
application of the NonCC subgroup criteria, in our annual analysis of 
MS-DRG classification requests, consistent with our approach since FY 
2021 when we finalized the expansion of the criteria to include the 
NonCC subgroup for a three-way severity level split. Accordingly, in 
our analysis of the MS-DRG classification requests for FY 2025 that we 
received by October 20, 2023, as well as any additional analyses that 
were conducted in connection with those requests, we applied these 
criteria to each of the MCC, CC, and NonCC subgroups, as described in 
the following table.

[[Page 35951]]

    In general, once the decision has been made to propose to make 
further modifications to the MS-DRGs as described previously, such as 
creating a new base MS-DRG, or in our evaluation of a specific MS-DRG 
classification request to split (or subdivide) an existing base MS-DRG 
into severity levels, all five criteria must be met for the base MS-DRG 
to be split (or subdivided) by a CC subgroup. We note that in our 
analysis of requests to create a new MS-DRG, we typically evaluate the 
most recent year of MedPAR claims data available. For example, we 
stated earlier that for this FY 2025 IPPS/LTCH PPS proposed rule, our 
MS-DRG analysis was based on ICD-10 claims data from the September 2023 
update of the FY 2023 MedPAR file. However, in our evaluation of 
requests to split an existing base MS-DRG into severity levels, as 
noted in prior rulemaking (80 FR 49368), we typically analyze the most 
recent 2 years of data. This analysis includes 2 years of MedPAR claims 
data to compare the data results from one year to the next to avoid 
making determinations about whether additional severity levels are 
warranted based on an isolated year's data fluctuation and also, to 
validate that the established severity levels within a base MS-DRG are 
supported. The first step in our process of evaluating if the creation 
of a new CC subgroup within a base MS-DRG is warranted is to determine 
if all the criteria is satisfied for a three-way split. In applying the 
criteria for a three-way split, a base MS-DRG is initially subdivided 
into the three subgroups: MCC, CC, and NonCC. Each subgroup is then 
analyzed in relation to the other two subgroups using the volume 
(Criteria 1 and 2), average cost (Criteria 3 and 4), and reduction in 
variance (Criteria 5). If the criteria fail, the next step is to 
determine if the criteria are satisfied for a two-way split. In 
applying the criteria for a two-way split, a base MS-DRG is initially 
subdivided into two subgroups: ``with MCC'' and ``without MCC'' (1_23) 
or ``with CC/MCC'' and ``without CC/MCC'' (12_3). Each subgroup is then 
analyzed in relation to the other using the volume (Criteria 1 and 2), 
average cost (Criteria 3 and 4), and reduction in variance (Criteria 
5). If the criteria for both of the two-way splits fail, then a split 
(or CC subgroup) would generally not be warranted for that base MS-DRG. 
If the three-way split fails on any one of the five criteria and all 
five criteria for both two-way splits (1_23 and 12_3) are met, we would 
apply the two-way split with the highest R2 value. We note that if the 
request to split (or subdivide) an existing base MS-DRG into severity 
levels specifies the request is for either one of the two-way splits 
(1_23 or 12_3), in response to the specific request, we will evaluate 
the criteria for both of the two-way splits; however, we do not also 
evaluate the criteria for a three-way split.
2. Pre-MDC MS-DRG 018 Chimeric Antigen Receptor (CAR) T-cell and Other 
Immunotherapies
    We received a request to revise the title of Pre-MDC MS-DRG 018 
(Chimeric Antigen Receptor (CAR) T-cell and Other Immunotherapies) in 
connection with an ICD-10-PCS procedure code request that was submitted 
via MEARISTM by the December 1, 2023 deadline for 
consideration as an agenda topic to be discussed at the March 19-20, 
2024 ICD-10 Coordination and Maintenance Committee meeting. The 
procedure code request involves the application of an autologous 
genetically engineered cell-based gene therapy, prademagene zamikeracel 
(PZ), that is indicated in the treatment of recessive dystrophic 
epidermolysis bullosa (RDEB), an extremely rare genetic disease of the 
skin that leads to large chronic wounds. The proposal was presented and 
discussed at the March 19-20, 2024 ICD-10 Coordination and Maintenance 
Committee meeting. We refer the reader to the CMS website at https://www.cms.gov/medicare/coding-billing/icd-10-codes/icd-10-coordination-maintenance-committee-materials for additional detailed information 
regarding the request, including a recording of the discussion and the 
related meeting materials. Public comments in response to the code 
proposal are due by April 19, 2024. The requestor suggested that if 
finalized, a new procedure code to identify the application of PZ 
should be assigned to Pre-MDC MS-DRG 018 and that the title for Pre-MDC 
MS-DRG 018 be revised to reflect ``Chimeric Antigen Receptor (CAR) T 
and Other Autologous Gene and Cell Therapies''.
    Because the diagnosis and procedure code proposals that are 
presented at the March ICD-10-CM Coordination and Maintenance Committee 
meeting for an October 1 implementation (upcoming FY) are not finalized 
in time to include in Table 6A.--New Diagnosis Codes and Table 6B.--New 
Procedure Codes in association with the proposed rule, as we have noted 
in prior rulemaking, we use our established process to examine the MS-
DRG assignment for the predecessor codes to determine the most 
appropriate MS-DRG assignment. Specifically, we review the predecessor 
code and MS-DRG assignment most closely associated with the new 
procedure code, and in the absence of claims data, we consider other 
factors

[[Page 35952]]

that may be relevant to the MS-DRG assignment, including the severity 
of illness, treatment difficulty, complexity of service and the 
resources utilized in the diagnosis and/or treatment of the condition. 
We have noted in prior rulemaking that this process does not 
automatically result in the new procedure code being assigned to the 
same MS-DRG or to have the same designation (O.R. versus Non-O.R.) as 
the predecessor code. Under this established process, the MS-DRG 
assignment for the upcoming fiscal year for any new diagnosis or 
procedure codes finalized after the March meeting would be reflected in 
Table 6A.--New Diagnosis Codes and Table 6B.--New Procedure Codes 
associated with the final rule for that fiscal year. Accordingly, the 
MS-DRG assignment for any new procedure codes describing PZ, if 
finalized following the March meeting, would be reflected in Table 
6B.--New Procedure Codes associated with the final rule for FY 2025. As 
noted in prior rulemaking (87 FR 28135), the codes that are finalized 
after the March meeting are specifically identified with a footnote in 
Table 6A.--New Diagnosis Codes and Table 6B.--New Procedure Codes that 
are made publicly available in association with the final rule on the 
CMS website at https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps. The public may provide feedback on 
these finalized assignments, which is then taken into consideration for 
the following fiscal year.
    We do not agree with the request to revise the title for Pre-MDC 
MS-DRG 018 for FY 2025 as requested because the logic for Pre-MDC MS-
DRG 018 is intended to include other immunotherapies and is not 
restricted to CAR T-cell and autologous gene and cell therapies. As 
discussed in the FY 2022 IPPS/LTCH PPS final rule (86 FR 44798 through 
44806), we finalized our proposal to revise the title of Pre-MDC MS-DRG 
018 to include ``Other Immunotherapies'' to better reflect the cases 
reporting the administration of non-CAR T-cell therapies and other 
immunotherapies that would also be assigned to this MS-DRG, in addition 
to CAR T-cell therapies. We noted that the term ``Other 
Immunotherapies'' is intended to encompass the group of therapies that 
are currently available and being utilized today (for which codes have 
been created for reporting in response to industry requests or are 
being considered for implementation), and to enable appropriate MS-DRG 
assignment for any future therapies that may also fit into this 
category and are not specifically identified as a CAR T-cell product, 
that may become available (for example receive marketing authorization 
or a newly established procedure code in the ICD-10-PCS 
classification).
    We also note, as discussed in prior rulemaking, that this category 
of therapies continues to evolve, and we are in the process of 
carefully considering the feedback we have previously received about 
ways in which we can continue to appropriately reflect resource 
utilization while maintaining clinical coherence and stability in the 
relative weights under the IPPS MS-DRGs. We appreciate the 
recommendations and suggestions for consideration we have received and 
will continue to examine these complex issues in connection with future 
rulemaking. We acknowledge that there may be distinctions to account 
for as we continue to gain more experience in the use of these 
therapies and have additional claims data to analyze. Therefore, we are 
not proposing to revise the title for Pre-MDC MS-DRG 018 to reflect 
``Chimeric Antigen Receptor (CAR) T and Other Autologous Gene and Cell 
Therapies'' at this time and are proposing to maintain the existing 
title to Pre-MDC MS-DRG 018, ``Chimeric Antigen Receptor (CAR) T-cell 
and Other Immunotherapies'' for FY 2025.
3. MDC 01 (Diseases and Disorders of the Nervous System)
a. Logic for MS-DRGs 023 Through 027
    In the FY 2024 IPPS/LTCH PPS final rule (88 FR 58661 through 
58667), we discussed a request to reassign cases describing the 
insertion of a neurostimulator generator into the skull in combination 
with the insertion of a neurostimulator lead into the brain from MS-DRG 
023 (Craniotomy with Major Device Implant or Acute Complex CNS 
Principal Diagnosis with MCC or Chemotherapy Implant or Epilepsy with 
Neurostimulator) to MS-DRG 021 (Intracranial Vascular Procedures with 
Principal Diagnosis Hemorrhage with CC) or reassign all cases currently 
assigned to MS-DRG 023 that involve a craniectomy or a craniotomy with 
the insertion of device implant and create a new MS-DRG for these 
cases.
    We stated the requestor acknowledged that the relatively low volume 
of cases that only involve the insertion of a neurostimulator generator 
into the skull in combination with the insertion of a neurostimulator 
lead into the brain in the claims data was likely not sufficient to 
warrant the creation of a new MS-DRG. The requestor further stated 
given the limited options within the existing MS-DRG structure that fit 
from both a cost and clinical cohesiveness perspective, they believed 
that MS-DRG 021 was the most logical fit in terms of average costs and 
clinical coherence for reassignment even though, according to the 
requestor, the insertion of a neurostimulator generator into the skull 
in combination with the insertion of a neurostimulator lead into the 
brain is technically more complex and involves a higher level of 
training, extreme precision and sophisticated technology than 
performing a craniectomy for hemorrhage.
    We noted that while our data findings demonstrated the average 
costs are higher for the cases with a principal diagnosis of epilepsy 
with a neurostimulator generator inserted into the skull and insertion 
of a neurostimulator lead into brain when compared to all cases in MS-
DRG 023, these cases represented a small percentage of the total number 
of cases reported in this MS-DRG. We stated that while we appreciated 
the requestor's concerns regarding the differential in average costs 
for cases describing the insertion of a neurostimulator generator into 
the skull in combination with the insertion of a neurostimulator lead 
into the brain when compared to all cases in their assigned MS-DRG, we 
believed additional time was needed to evaluate these cases as part of 
our ongoing examination of the case logic to the MS-DRGs for craniotomy 
and endovascular procedures, which are MS-DRG 023, MS-DRG 024 
(Craniotomy with Major Device Implant or Acute Complex CNS Principal 
Diagnosis without MCC), and MS-DRGs 025, 026, and 027 (Craniotomy and 
Endovascular Intracranial Procedures with MCC, with CC, and without CC/
MCC, respectively).
    As discussed in the FY 2023 IPPS/LTCH PPS final rule (87 FR 48808 
through 48820), in connection with our analysis of cases reporting 
laser interstitial thermal therapy (LITT) procedures performed on the 
brain or brain stem in MDC 01, we stated we have started to examine the 
logic for case assignment to MS-DRGs 023 through 027 to determine where 
further refinements could potentially be made to better account for 
differences in the technical complexity and resource utilization among 
the procedures that are currently assigned to those MS-DRGs. We stated 
that specifically, we were in the process of evaluating procedures that 
are performed using an open craniotomy (where it is necessary to 
surgically remove a portion of the skull) versus a percutaneous burr 
hole

[[Page 35953]]

(where a hole approximately the size of a pencil is drilled) to obtain 
access to the brain in the performance of a procedure. We stated we 
were also reviewing the indications for these procedures, for example, 
malignant neoplasms versus epilepsy to consider if there may be merit 
in considering restructuring the current MS-DRGs to better recognize 
the clinical distinctions of these patient populations in the MS-DRGs.
    As part of this evaluation, as discussed in the FY 2024 IPPS/LTCH 
PPS final rule, we have begun to analyze the ICD-10 coded claims data 
to determine if the patients' diagnoses, the objective of the procedure 
performed, the specific anatomical site where the procedure is 
performed or the surgical approach used (for example, open, 
percutaneous, percutaneous endoscopic, among others) demonstrates a 
greater severity of illness and/or increased treatment difficulty as we 
consider restructuring MS-DRGs 023 through 027, including how to better 
align the clinical indications with the performance of specific 
intracranial procedures. We referred the reader to Tables 6P.2b through 
6P.2f associated with the FY 2024 IPPS/LTCH PPS proposed rule 
(available on the CMS website at: https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps) for data analysis 
findings of cases assigned to MS-DRGs 023 through 027 from the 
September 2022 update of the FY 2022 MedPAR file as we continue to look 
for patterns of complexity and resource intensity.
    In summary, we stated that while we agreed that neurostimulator 
cases can have average costs that are higher than the average costs of 
all cases in their respective MS-DRGs, in our analysis of this issue, 
it was difficult to detect patterns of complexity and resource 
intensity. Therefore, for the reasons discussed, we finalized our 
proposal to maintain the current assignment of cases describing a 
neurostimulator generator inserted into the skull with the insertion of 
a neurostimulator lead into the brain for FY 2024.
    In the FY 2024 IPPS/LTCH PPS final rule, we stated we continue to 
believe that additional time is needed to evaluate these cases as part 
of our ongoing examination of the case logic for MS-DRGs 023 through 
027. As part of our ongoing, comprehensive analysis of the MS-DRGs 
under ICD-10, we stated we would continue to explore mechanisms to 
ensure clinical coherence between these cases and the other cases with 
which they may potentially be grouped. We stated that the data analysis 
as displayed in Tables 6P.2b through 6P.2f associated with the FY 2024 
IPPS/LTCH PPS proposed rule was displayed to provide the public an 
opportunity to review our examination of the procedures by their 
approach (open versus percutaneous), clinical indications, and 
procedures that involve the insertion or implantation of a device and 
to reflect on what factors should be considered in the potential 
restructuring of these MS-DRGs. We welcomed further feedback on how CMS 
should define technical complexity, what factors should be considered 
in the analysis, and whether there are other data not included in 
Tables 6P.2b through 6P.2f that CMS should analyze. We also stated we 
are interested in receiving feedback on where further refinements could 
potentially be made to better account for differences in the technical 
complexity and resource utilization among the procedures that are 
currently assigned to these MS-DRGs.
    In response to this discussion in the FY 2024 IPPS/LTCH PPS final 
rule, we received two comments by the October 20, 2023 deadline. A 
commenter recommended that CMS not use surgical approach (for example, 
open versus percutaneous) as a factor to reclassify MS-DRGs 023 through 
027. The commenter stated whether the opening is created via a drill 
into the skull percutaneously or through a larger incision in the skull 
for a craniotomy, both approaches involve the risk of intracranial 
bleeding, infection, and brain swelling. The commenter further stated 
they do not support a consideration of the reassignment of the ICD-10-
PCS procedure codes describing LITT, currently assigned to MS-DRGs 025 
through 027, based on the diagnosis being treated. The commenter stated 
that the LITT procedure requires the same steps, time, and clinical 
resources when performed for brain cancer or epilepsy. In the 
requestor's view, differences in the disease causing the tumors or 
lesions do not affect the resources used for performing the procedure 
or the post-operative care for the patient. Lastly, the commenter 
stated they support the current structure of MS-DRGs 023 and 024 based 
on an acute complicated principal diagnosis, or chemotherapy implant, 
or epilepsy with neurostimulator. The commenter stated these diagnoses 
represent severe complex conditions that require immediate and urgent 
intervention.
    Another commenter stated that the current logic for MS-DRGs 023 
through 027 is sufficient and supports the clinical and resource 
similarities of the procedures reflected in these MS-DRGs. The 
commenter performed its own analysis and stated they found that 
realignment based on surgical approach or root operation could create 
significant new inequities. The commenter recommended that CMS maintain 
the current logic for MS-DRGs 025 through 027, as making changes could 
be disruptive to hospitals and create challenges for Medicare 
beneficiary access to life-saving technologies. The commenter stated 
they strongly believe that maintaining the current structure provides 
payment stability and integrity of these procedures over time.
    CMS appreciates the comments submitted in response to the request 
for feedback in the FY 2024 IPPS/LTCH PPS final rule. As we continue 
analysis of the claims data with respect to MS-DRGs 023 through 027, we 
continue to seek public comments and feedback on other factors that 
should be considered in the potential restructuring of these MS-DRGs. 
As stated in prior rulemaking, we recognize the logic for MS-DRGs 023 
through 027 has grown more complex over the years and believe there is 
opportunity for further refinement. We refer the reader to the ICD-10 
MS-DRG Definitions Manual, Version 41.1 (available on the CMS website 
at: https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps/ms-drg-classifications-and-software) for complete 
documentation of the GROUPER logic for MS-DRGs 023 through 027. 
Feedback and other suggestions may continue to be directed to 
MEARISTM, discussed in section II.C.1.b. of the preamble of 
this proposed rule at: https://mearis.cms.gov/public/home.
b. Intraoperative Radiation Therapy (IORT)
    We received a request to add ICD-10-PCS procedure codes D0Y0CZZ 
(Intraoperative radiation therapy (IORT) of brain) and D0Y1CZZ 
(Intraoperative radiation therapy (IORT) of brain stem), to the 
Chemotherapy Implant logic list in MS-DRG 023 (Craniotomy with Major 
Device Implant or Acute Complex CNS Principal Diagnosis with MCC or 
Chemotherapy Implant or Epilepsy with Neurostimulator). According to 
the requestor, intraoperative radiation therapy (IORT) for the brain is 
always performed as part of the surgery to remove a brain tumor during 
the same operative episode. The requestor stated that once maximal safe 
tumor resection is achieved, the tumor cavity is examined for active 
egress of cerebrospinal fluid or bleeding. Next,

[[Page 35954]]

intraoperative measurements are made using neuro-navigation or 
intraoperative imaging such as magnetic resonance imaging (MRI) or 
computed tomography (CT) to ensure safe distance to organs or tissues 
at risk, aid in appropriate dose calculation, and selection of proper 
applicator size. The applicator is then implanted into the tumor cavity 
and the radiation dose is delivered. The requestor stated that delivery 
time can be up to 40 minutes and upon completion of the treatment, the 
source is removed, and the cavity is re-inspected for active egress of 
cerebrospinal fluid and bleeding.
    The requestor stated that currently the ICD-10-PCS procedure codes 
for excision of a brain tumor, 00B00ZZ (Excision of brain, open 
approach) and 00B70ZZ (Excision of cerebral hemisphere, open approach) 
map to both sets of craniotomy MS-DRGs. Specifically, MS-DRG 023 
(Craniotomy with Major Device Implant or Acute Complex CNS Principal 
Diagnosis with MCC or Chemotherapy Implant or Epilepsy with 
Neurostimulator) and MS-DRG 024 (Craniotomy with Major Device Implant 
or Acute Complex CNS Principal Diagnosis without MCC), and MS-DRGs 025, 
026, and 027 (Craniotomy and Endovascular Intracranial Procedures with 
MCC, with CC, and without CC/MCC, respectively). However, the requestor 
also stated that the procedure codes describing IORT (D0Y0CZZ or 
D0Y1CZZ) are not listed in the GROUPER logic and do not affect MS-DRG 
assignment. Therefore, cases reporting a procedure code describing 
excision of a brain tumor (00B00ZZ or 00B70ZZ) with IORT currently map 
to MS-DRGs 025, 026, and 027. The requestor suggested that cases 
reporting a procedure code describing excision of a brain tumor 
(00B00ZZ or 00B70ZZ) with IORT (D0Y0CZZ or D0Y1CZZ) should map to MS-
DRG 023 because of the higher costs associated with the addition of 
IORT to the excision of brain tumor surgery. According to the 
requestor, MS-DRG 023 includes complicated craniotomy cases involving 
the placement of radiological sources and chemotherapy implants. The 
requestor stated that because IORT involves a full course of radiation 
therapy delivered directly to the tumor bed via an applicator that is 
implanted into the tumor cavity during the same surgical session and is 
clinically similar to two other procedures listed in the Chemotherapy 
Implant logic list, it should also be included in the Chemotherapy 
Implant logic list. Specifically, the requestor stated procedure code 
00H004Z (Insertion of radioactive element, cesium-131 collagen implant 
into brain, open approach) and procedure code 3E0Q305 (Introduction of 
other antineoplastic into cranial cavity and brain, percutaneous 
approach) also involve the delivery of either radiation or chemotherapy 
directly after tumor resection. According to the requestor, the 
resources involved in placing the delivery device are similar for all 
three procedures and the distinction is that the procedures described 
by codes 00H004Z and 3E0Q305 involve the insertion of devices that 
deliver radiation or chemotherapy over a period of time, whereas IORT 
delivers the entire dose of radiation during the operative session. As 
such, the requestor asserted that IORT is clinically aligned with the 
other procedures from a therapeutic and resource utilization 
perspective.
    The requestor performed its own analysis using the FY 2022 MedPAR 
file that was made available in association with the FY 2024 IPPS/LTCH 
PPS final rule and stated it found fewer than 11 cases reporting IORT 
in MS-DRGs 025, 026, and 027, with the majority of those cases mapping 
to MS-DRG 025. According to the requestor, the volume of claims 
reporting IORT is anticipated to increase as appropriate use of the 
technology is adopted.
    The requestor is correct that currently, the logic for case 
assignment to MS-DRG 023 includes a Chemotherapy Implant logic list and 
the procedure codes that identify IORT (D0Y0CZZ and D0Y1CZZ) are not 
listed in the GROUPER logic and do not affect MS-DRG assignment as the 
procedures are designated as non-O.R. procedures. The requestor is also 
correct that cases reporting a procedure code describing excision of a 
brain tumor (00B00ZZ or 00B70ZZ) with IORT currently map to MS-DRGs 
025, 026, and 027. We refer the reader to the ICD-10 MS-DRG Definitions 
Manual Version 41.1 (available on the CMS website at: https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps/ms-drg-classifications-and-software) for complete 
documentation of the GROUPER logic.
    In review of this request, we analyzed claims data from the 
September 2023 update of the FY 2023 MedPAR file for MS-DRGs 023, 024, 
025, 026, and 027 and for cases reporting excision of brain tumor and 
IORT. We identified claims reporting excision of brain tumor with 
procedure code 00B00ZZ or 00B70ZZ and identified claims reporting IORT 
with procedure code D0Y0CZZ or D0Y1CZZ. The findings from our analysis 
are shown in the following table. We note that there were no cases 
found to report IORT of brain (D0Y0CZZ) or brain stem (D0Y1CZZ) with 
excision of brain (00B00ZZ) or excision of cerebral hemisphere 
(00B70ZZ).

BILLING CODE 4120-01-C
    As the data show, there were no cases found to report the use of 
IORT in the performance of a brain tumor excision; therefore, we are 
unable to evaluate whether the use of IORT directly impacts resource 
utilization. For this reason, we are proposing to maintain the current 
structure of MS-DRGs 023, 024, 025, 026, and 027 for FY 2025. We will 
continue to monitor the claims data in consideration of any future 
modifications to the MS-DRGs for which IORT may be reported.
4. MDC 05 (Diseases and Disorders of the Circulatory System)
a. Concomitant Left Atrial Appendage Closure and Cardiac Ablation
    We received a request to create a new MS-DRG to better accommodate 
the costs of concomitant left atrial appendage closure and cardiac 
ablation for atrial fibrillation in MDC 05 (Diseases and Disorders of 
the Circulatory System). Atrial fibrillation (AF) is an irregular and 
often rapid heart rate that occurs when the two upper chambers of the 
heart experience chaotic electrical signals. AF presents as either 
paroxysmal (lasting <7 days), persistent (lasting >7 day, but less than 
1 year), or long standing persistent (chronic) (lasting >1 year) based 
on time duration and can increase the risk for stroke, heart failure, 
and mortality. Management of AF has two primary goals: optimizing 
cardiac output through rhythm or rate control and decreasing the risk 
of cerebral and systemic thromboembolism. Among patients with AF, 
thrombus in the left atrial appendage (LAA) is a primary source for 
thromboembolism. Left Atrial Appendage Closure (LAAC) is a surgical or 
minimally invasive procedure to seal off the LAA to reduce the risk of 
embolic stroke.
    According to the requestor, the manufacturer of the 
WATCHMANTM Left Atrial Appendage Closure (LAAC) device, 
patients who are indicated for a LAAC device can also have symptomatic 
AF. For these patients, performing a cardiac ablation and LAAC 
procedure at the same time is ideal. Cardiac ablation is a procedure 
that works by burning or freezing tissue on the inside of the heart to 
disrupt faulty electrical signals causing the arrhythmia, which can 
help the heart maintain a normal heart rhythm. The requestor 
highlighted a recent study (Piccini et al. Left atrial appendage 
occlusion with the WATCHMANTM FLX and concomitant catheter 
ablation procedures. Heart Rhythm Society Meeting 2023, May 19, 2023; 
New Orleans, LA.). According to the requestor, the results of this 
study indicate that when LAAC is performed concomitantly with cardiac 
ablation, the outcomes are comparable to patients who have undergone 
these procedures separately.

[[Page 35957]]

    The requestor identified the following potential procedure code 
combination that would comprise a concomitant left atrial appendage 
closure and cardiac ablation procedure: ICD-10-PCS procedure code 
02L73DK (Occlusion of left atrial appendage with intraluminal device, 
percutaneous approach), that identifies the WATCHMANTM 
device, in combination with 02583ZZ (Destruction of conduction 
mechanism, percutaneous approach). The requestor performed its own 
analysis of this procedure code combination and stated that it found 
the average costs of cases reporting concomitant left atrial appendage 
closure and cardiac ablation procedures were consistently higher 
compared to the average costs of other cases within their respective 
MS-DRG, which it asserted could limit beneficiary access to these 
procedures. The requestor asserted that improved Medicare payment for 
providers who perform these procedures concomitantly would help 
Medicare patients to gain better access to these lifesaving and 
quality-improving services and decrease the risk of future readmissions 
and the need for future procedures.
    We reviewed this request and noted concerns regarding making 
proposed MS-DRG changes based on a specific, single technology (the 
WATCHMANTM Left Atrial Appendage Closure (LAAC) device) 
identified by only one unique procedure code versus considering 
proposed changes based on a group of related procedure codes that can 
be reported to describe the same type or class of technology, which is 
more consistent with the intent of the MS-DRGs. Therefore, in reviewing 
this request, we identified eight additional ICD-10-PCS procedure codes 
that describe LAAC procedures and included these codes in our analysis. 
The nine codes we identified are listed in the following table.
[GRAPHIC] [TIFF OMITTED] TP02MY24.005

    Similarly, as noted previously, the requestor identified code 
02583ZZ (Destruction of conduction mechanism, percutaneous approach) to 
describe cardiac ablation. In our review of the ICD-10-PCS 
classification, we identified 26 additional ICD-10-PCS codes that 
describe cardiac ablation that we also examined. The 27 codes we 
included in our analysis are listed in the following table.
[GRAPHIC] [TIFF OMITTED] TP02MY24.006


[[Page 35958]]


    In the ICD-10 MS-DRGs Definitions Manual Version 41.1, for 
concomitant left atrial appendage closure and cardiac ablation 
procedures, the GROUPER logic assigns MS-DRGs 273 and 274 (Percutaneous 
and Other Intracardiac Procedures with and without MCC, respectively) 
depending on the presence of any additional MCC secondary diagnoses. We 
examined claims data from the September 2023 update of the FY 2023 
MedPAR file for all cases in MS-DRGs 273 and 274 and compared the 
results to cases reporting procedure codes describing concomitant left 
atrial appendage closure and cardiac ablation. Our findings are shown 
in the following table.
[GRAPHIC] [TIFF OMITTED] TP02MY24.007

    As shown in the table, in MS-DRG 273, we identified a total of 
7,250 cases with an average length of stay of 5.4 days and average 
costs of $35,197. Of those 7,250 cases, there were 80 cases reporting 
procedure codes describing concomitant left atrial appendage closure 
and cardiac ablation with average costs higher than the average costs 
in the FY 2023 MedPAR file for MS-DRG 273 ($70,447 compared to $35,197) 
and a slightly longer average length of stay (5.8 days compared to 5.4 
days). In MS-DRG 274, we identified a total of 47,801 cases with an 
average length of stay of 1.4 days and average costs of $29,209. Of 
those 47,801 cases, there were 781 cases reporting procedure codes 
describing concomitant left atrial appendage closure and cardiac 
ablation, with average costs higher than the average costs in the FY 
2023 MedPAR file for MS-DRG 274 ($66,277 compared to $29,209) and a 
slightly longer average length of stay (1.5 days compared to 1.4 days).
    We reviewed these data and note, clinically, the management of AF 
by performing concomitant left atrial appendage closure and cardiac 
ablation can improve symptoms, prevent stroke, and reduce the risk of 
bleeding compared with oral anticoagulants. The data analysis clearly 
shows that cases reporting concomitant left atrial appendage closure 
and cardiac ablation procedures have higher average costs and slightly 
longer lengths of stay compared to all the cases in their assigned MS-
DRG. For these reasons, we are proposing to create a new MS-DRG for 
cases reporting a LAAC procedure and a cardiac ablation procedure.
    To compare and analyze the impact of our suggested modifications, 
we ran a simulation using the claims data from the September 2023 
update of the FY 2023 MedPAR file. The following table illustrates our 
findings for all 1,723 cases reporting procedure codes describing 
concomitant left atrial appendage closure and cardiac ablation. We 
believe the resulting proposed MS-DRG assignment is more clinically 
homogeneous, coherent and better reflects hospital resource use.
[GRAPHIC] [TIFF OMITTED] TP02MY24.008

    We applied the criteria to create subgroups in a base MS-DRG as 
discussed in section II.C.1.b. of this FY 2025 IPPS/LTCH PPS proposed 
rule. As shown in the table that follows, a three-way split of the 
proposed new MS-DRGs failed the criterion that there be at least 500 
cases for each subgroup due to low volume. Specifically, for the ``with 
MCC'' split, there were only 268 cases in the subgroup.
[GRAPHIC] [TIFF OMITTED] TP02MY24.009

    We then applied the criteria for a two-way split for the ``with CC/
MCC'' and ``without CC/MCC'' subgroups and found that the criterion 
that there be at least a 20% difference in average cost between 
subgroups could not be met. The following table illustrates our 
findings.
[GRAPHIC] [TIFF OMITTED] TP02MY24.010


[[Page 35959]]


    We also applied the criteria for a two-way split for the ``with 
MCC'' and ``without MCC'' subgroups and found that the criterion that 
there be at least 500 or more cases in each subgroup similarly could 
not be met. The criterion that there be at least a 20% difference in 
average costs between the subgroups also was not met. The following 
table illustrates our findings.
[GRAPHIC] [TIFF OMITTED] TP02MY24.011

    Therefore, for FY 2025, we are not proposing to subdivide the 
proposed new MS-DRG for cases reporting procedure codes describing 
concomitant left atrial appendage closure and cardiac ablation into 
severity levels.
    In summary, for FY 2025, taking into consideration that it 
clinically requires greater resources to perform concomitant left 
atrial appendage closure and cardiac ablation procedures, we are 
proposing to create a new base MS-DRG for cases reporting a LAAC 
procedure and a cardiac ablation procedure in MDC 05. The proposed new 
MS-DRG is proposed new MS-DRG 317 (Concomitant Left Atrial Appendage 
Closure and Cardiac Ablation). We are also proposing to include the 
nine ICD-10-PCS procedure codes that describe LAAC procedures and 27 
ICD-10-PCS procedure codes that describe cardiac ablation listed 
previously in the logic for assignment of cases reporting a LAAC 
procedure and a cardiac ablation procedure for the proposed new MS-DRG. 
We note that discussion of the surgical hierarchy for the proposed 
modification is discussed in section II.C.15. of this proposed rule.
b. Neuromodulation Device Implant for Heart Failure 
(BarostimTM Baroreflex Activation Therapy)
    The BAROSTIMTM system is the first neuromodulation 
device system designed to trigger the body's main cardiovascular reflex 
to target symptoms of heart failure. The system consists of an 
implantable pulse generator (IPG) that is implanted subcutaneously in 
the upper chest below the clavicle, a stimulation lead that is sutured 
to either the right or left carotid sinus to activate the baroreceptors 
in the wall of the carotid artery, and a wireless programmer system 
that is used to non-invasively program and adjust BAROSTIMTM 
therapy via telemetry. The BAROSTIMTM system is indicated 
for the improvement of symptoms of heart failure in a subset of 
patients with symptomatic New York Heart Association (NYHA) Class III 
or Class II (who had a recent history of Class III) heart failure, with 
a low left ventricular ejection fraction, who also do not benefit from 
guideline directed pharmacologic therapy or qualify for Cardiac 
Resynchronization Therapy (CRT). The BAROSTIMTM system was 
approved for new technology add-on payments for FY 2021 (85 FR 58716 
through 58717) and FY 2022 (86 FR 44974). The new technology add-on 
payment was subsequently discontinued effective FY 2023 (87 FR 48916).
    In the FY 2023 IPPS/LTCH PPS final rule (87 FR 48837 through 
48843), we discussed a request we received to reassign the ICD-10-PCS 
procedure codes that describe the implantation of the 
BAROSTIMTM system from MS-DRGs 252, 253, and 254 (Other 
Vascular Procedures with MCC, with CC, and without MCC respectively) to 
MS-DRGs 222, 223, 224, 225, 226, and 227 (Cardiac Defibrillator Implant 
with and without Cardiac Catheterization with and without AMI/HF/Shock 
with and without MCC, respectively). The requestor stated that the 
subset of patients that have an indication for the implantation of a 
BAROSTIMTM system also have indications for the implantation 
of Implantable Cardioverter Defibrillators (ICD), Cardiac 
Resynchronization Therapy Defibrillators (CRT-D) and/or Cardiac 
Contractility Modulation (CCM) devices, all of which also require the 
permanent implantation of a programmable, electrical pulse generator 
and at least one electrical lead. The requestor further stated that the 
average resource utilization required to implant the 
BAROSTIMTM system demonstrates a significant disparity 
compared to all procedures within MS-DRGs 252, 253, and 254.
    In the FY 2023 IPPS/LTCH PPS final rule, we stated that the results 
of the claims analysis demonstrated we did not have sufficient claims 
data on which to base and evaluate any proposed changes to the current 
MS-DRG assignment. We also expressed concern in equating the 
implantation of a BAROSTIMTM system to the placement of ICD, 
CRT-D, and CCM devices as these devices all differ in terms of 
technical complexity and anatomical placement of the electrical 
lead(s). We noted there is no intravascular component or vascular 
puncture involved when implanting a BAROSTIMTM system. In 
contrast, the placement of ICD, CRT-D, and CCM devices generally 
involve a lead being affixed to the myocardium, being threaded through 
the coronary sinus or crossing a heart valve and are procedures that 
involve a greater level of complexity than affixing the stimulator lead 
to either the right or left carotid sinus when implanting a 
BAROSTIMTM system. We stated that we believed that as the 
number of cases reporting procedure codes describing the implantation 
of neuromodulation devices for heart failure increases, a better view 
of the associated costs and lengths of stay on average will be 
reflected in the data for purposes of assessing any reassignment of 
these cases. Therefore, after consideration of the public comments we 
received, and for the reasons stated earlier, we finalized our proposal 
to maintain the assignment of cases reporting procedure codes that 
describe the implantation of a neuromodulation device in MS-DRGs 252, 
253, and 254 for FY 2023.
    In the FY 2024 IPPS/LTCH PPS final rule (88 FR 58712 through 
58720), we discussed a request we received to add ICD-10-CM diagnosis 
code R57.0 (Cardiogenic shock) to the list of ``secondary diagnoses'' 
that grouped to MS-DRGs 222 and 223 (Cardiac Defibrillator Implant with 
Cardiac Catheterization with Acute Myocardial Infarction (AMI), Heart 
Failure (HF), or Shock with and without MCC, respectively). During our 
review of the issue, we noted that the results of our claims analysis 
showed that in procedures involving a cardiac defibrillator implant, 
the average costs and length of stay were generally similar without 
regard to the presence of diagnosis codes describing AMI, HF, or shock. 
We stated we believed that it may no longer be necessary to subdivide 
MS-DRGs 222, 223, 224, 225, 226, and 227 based on the diagnosis codes 
reported. After consideration of the public comments we received, and 
for the reasons stated in the rule, we finalized our proposal to delete 
MS-

[[Page 35960]]

DRGs 222, 223, 224, 225, 226, and 227. We also finalized our proposal 
to create new MS-DRG 275 (Cardiac Defibrillator Implant with Cardiac 
Catheterization and MCC), new MS-DRG 276 (Cardiac Defibrillator Implant 
with MCC) and new MS-DRG 277 (Cardiac Defibrillator Implant without 
MCC) in MDC 05 for FY 2024.
    For this FY 2025 IPPS/LTCH PPS proposed rule, we received a similar 
request to again review the MS-DRG assignment of the ICD-10-PCS 
procedure codes that describe the implantation of the 
BAROSTIMTM system. Specifically, the requestor recommended 
that CMS consider reassigning the ICD-10-PCS procedure codes that 
describe the implantation of the BAROSTIMTM system from MS-
DRGs 252, 253, and 254 (Other Vascular Procedures with MCC, with CC, 
and without MCC respectively) to MS-DRGs 275 (Cardiac Defibrillator 
Implant with Cardiac Catheterization and MCC), MS-DRG 276, and 277 
(Cardiac Defibrillator Implant with MCC and without MCC respectively); 
or to other more clinically coherent MS-DRGs for implantable device 
procedures indicated for Class III heart failure patients. The 
requestor stated in their analysis the number of claims reporting 
procedure codes that describe the implantation of the 
BAROSTIMTM system has been consistently growing over the 
past few years. The requestor acknowledged that the implantation of the 
BAROSTIMTM system is predominantly performed in the 
outpatient setting but noted that a significant number of severely sick 
patients with multiple comorbidities (such as chronic kidney disease, 
end stage renal disease (ESRD), chronic obstructive pulmonary disease 
(COPD), and AF) are treated in an inpatient setting. The requestor 
stated in their experience, hospitals that have performed 
BAROSTIMTM procedures have stopped allowing patients to 
receive the device in the inpatient setting due to the high losses for 
each Medicare claim. The requestor asserted it is critically important 
to allow very sick and fragile patients access to the 
BAROSTIMTM procedure in an inpatient setting and stated 
these patients should not be denied access by hospitals due to the 
perceived gross underpayment of the current MS-DRG.
    The requestor stated the BAROSTIMTM procedure is not 
clinically coherent with other procedures assigned to MS-DRGs 252, 253, 
and 254 (Other Vascular Procedures) as the majority of the ICD-10-PCS 
codes assigned to MS-DRGs 252, 253, and 254 describe procedures to 
identify, diagnose, clear and restructure veins and arteries, excluding 
those that require implantable devices. Furthermore, the requestor 
stated the costs of the implantable medical devices used for the 
BAROSTIMTM system (that is, the electrical pulse generator 
and electrical lead) alone far exceed the average costs of other cases 
assigned to MS-DRGs 252, 253, and 254.
    The following ICD-10-PCS procedure codes uniquely identify the 
implantation of the BAROSTIMTM system: 0JH60MZ (Insertion of 
stimulator generator into chest subcutaneous tissue and fascia, open 
approach) in combination with 03HK3MZ (Insertion of stimulator lead 
into right internal carotid artery, percutaneous approach) or 03HL3MZ 
(Insertion of stimulator lead into left internal carotid artery, 
percutaneous approach).
    To analyze this request, we first examined claims data from the 
September 2023 update of the FY 2023 MedPAR file for MS-DRGs 252, 253, 
and 254 to identify cases reporting procedure codes describing the 
implantation of the BAROSTIMTM system with or without a 
procedure code describing the performance of a cardiac catheterization 
as MS-DRG 275 is defined by the performance of cardiac catheterization 
and a secondary diagnosis of MCC. Our findings are shown in the 
following table.
[GRAPHIC] [TIFF OMITTED] TP02MY24.012

    As shown in the table, in MS-DRG 252, we identified a total of 
18,964 cases with an average length of stay of 8 days and average costs 
of $30,456. Of those 18,964 cases, there was one case reporting 
procedure codes describing

[[Page 35961]]

the implantation of the BAROSTIMTM system with a procedure 
code describing the performance of a cardiac catheterization with costs 
higher than the average costs in the FY 2023 MedPAR file for MS-DRG 252 
($110,928 compared to $30,456) and a longer length of stay (9 days 
compared to 8 days). There were 12 cases reporting procedure codes 
describing the implantation of the BAROSTIMTM system without 
a procedure code describing the performance of a cardiac 
catheterization, with average costs higher than the average costs in 
the FY 2023 MedPAR file for MS-DRG 252 ($66,291 compared to $30,456) 
and a slighter shorter average length of stay (7.8 days compared to 8 
days). In MS-DRG 253, we identified a total of 15,551 cases with an 
average length of stay of 5.2 days and average costs of $22,870. Of 
those 15,551 cases, there were seven cases reporting procedure codes 
describing the implantation of the BAROSTIMTM system without 
a procedure code describing the performance of a cardiac 
catheterization, with average costs higher than the average costs in 
the FY 2023 MedPAR file for MS-DRG 253 ($52,788 compared to $22,870) 
and a shorter average length of stay (4 days compared to 5.2 days). We 
found zero cases in MS-DRG 253 reporting procedure codes describing the 
implantation of a BAROSTIMTM system with a procedure code 
describing the performance of a cardiac catheterization. In MS-DRG 254, 
we identified a total of 5,973 cases with an average length of stay of 
2.3 days and average costs of $15,778. Of those 5,973 cases, there were 
three cases reporting procedure codes describing the implantation of 
the BAROSTIMTM system without a procedure code describing 
the performance of a cardiac catheterization, with average costs higher 
than the average costs in the FY 2023 MedPAR file for MS-DRG 254 
($29,740 compared to $15,778) and a shorter average length of stay (1.3 
days compared to 2.3 days). We found zero cases in MS-DRG 254 reporting 
procedure codes describing the implantation of a BAROSTIMTM 
system with a procedure code describing the performance of a cardiac 
catheterization.
    We then examined claims data from the September 2023 update of the 
FY 2023 MedPAR file for MS-DRGs 275, 276, and 277. Our findings are 
shown in the following table.
[GRAPHIC] [TIFF OMITTED] TP02MY24.013

    As the table shows, for MS-DRG 275, there were a total of 3,358 
cases with an average length of stay of 10.3 days and average costs of 
$63,181. For MS-DRG 276, there were a total of 3,264 cases with an 
average length of stay of 8.2 days and average costs of $54,993. For 
MS-DRG 277, there were a total of 3,840 cases with an average length of 
stay of 4.2 days and average costs of $42,111.
    In exploring mechanisms to address this request, we noted in total, 
there were only 23 cases reporting procedure codes describing the 
implantation of a BAROSTIMTM system in MS-DRGs 252, 253, and 
254 (13, 7, and 3, respectively). We reviewed these data, and while we 
recognize that the average costs of the 23 cases reporting procedure 
codes describing the implantation of a BAROSTIMTM are 
greater when compared to the average costs of all cases in MS-DRGs 252, 
253, and 254, the number of cases continues to be too small to warrant 
the creation of a new MS-DRG for these cases.
    We further note, that of the 23 cases reporting procedure codes 
describing the implantation of a BAROSTIMTM system 
identified in MS-DRGs 252, 253, and 254, only one case reported the 
performance of cardiac catheterization. As discussed in the FY 2024 
IPPS/LTCH PPS final rule, when reviewing the consumption of hospital 
resources for the cases reporting a cardiac defibrillator implant with 
cardiac catheterization during a hospital stay, the claims data clearly 
showed that the cases reporting secondary diagnoses designated as MCCs 
were more resource intensive as compared to other cases reporting 
cardiac defibrillator implant. Therefore, we finalized the creation of 
MS-DRG 275 for cases reporting a cardiac defibrillator implant with 
cardiac catheterization and a secondary diagnosis designated as an MCC. 
Of the 23 cases reporting procedure codes describing the implantation 
of a BAROSTIMTM system, there was only one case reporting a 
procedure code describing the performance of cardiac catheterization 
and a secondary diagnosis designated as an MCC, and we note that there 
may have been other factors contributing to the higher costs of this 
one case. The results of the claims analysis demonstrate we do not have 
sufficient claims data on which to base and propose a change to the 
current MS-DRG assignment of cases reporting procedure codes describing 
the implantation of a BAROSTIMTM system from MS-DRGs 252, 
253, and 254 to MS-DRG 275.
    Further analysis of the claims data demonstrates that the 23 cases 
reporting procedure codes describing the implantation of a 
BAROSTIMTM system had an average length of stay of 5.8 days 
and average costs of $59,355, as compared to the 3,264 cases in MS-DRG 
276 that had an average length of stay of 8.2 days and average costs of 
$54,993. While the cases reporting procedure codes describing the 
implantation of a BAROSTIMTM system had average costs that 
were $4,362 higher than the average costs of all cases in MS-DRG 276, 
as noted, there were only a total of 23 cases, and there may have been 
other factors contributing to the higher costs. We noted, however, 
reassigning all cases reporting procedure codes describing the 
implantation of a BAROSTIMTM system to MS-DRG 276, even if 
there is not a MCC present, the cases would receive higher payment and 
better account for the differences in resource utilization of these 
cases than in their respective MS-DRG.
    We reviewed the clinical issues and the claims data, and while we 
continue to note that there is no intravascular component or vascular 
puncture involved when implanting a BAROSTIMTM system, and 
that the implantation of a BAROSTIMTM system is 
distinguishable from the placement of ICD, CRT-D, and CCM devices, as 
these devices all differ in terms of technical complexity and 
anatomical placement of the electrical lead(s), as discussed in the FY 
2023 IPPS/LTCH PPS final rule (87 FR 48837 through 48843), we agree 
that ICD, CRT-D, and CCM devices and the BAROSTIMTM system 
are clinically coherent in that they share an indication of heart 
failure, a major cause of morbidity and mortality in the United States, 
and that these cases demonstrate comparable resource utilization. Based 
on our review of the clinical issues and

[[Page 35962]]

the claims data, and to better account for the resources required, we 
are proposing to reassign the cases reporting procedure codes 
describing the implantation of a BAROSTIMTM system to MS-DRG 
276, even if there is no MCC reported, to better reflect the clinical 
severity and resource use involved in these cases.
    Therefore, for FY 2025, we are proposing to reassign all cases with 
one of the following ICD-10-PCS code combinations capturing cases 
reporting procedure codes describing the implantation of a 
BAROSTIMTM system, to MS-DRG 276, even if there is no MCC 
reported:
     0JH60MZ (Insertion of stimulator generator into chest 
subcutaneous tissue and fascia, open approach) in combination with 
03HK3MZ (Insertion of stimulator lead into right internal carotid 
artery, percutaneous approach); and
     0JH60MZ (Insertion of stimulator generator into chest 
subcutaneous tissue and fascia, open approach) in combination with 
03HL3MZ (Insertion of stimulator lead into left internal carotid 
artery, percutaneous approach).
    We also are proposing to change the title of MS-DRG 276 from 
``Cardiac Defibrillator Implant with MCC'' to ``Cardiac Defibrillator 
Implant with MCC or Carotid Sinus Neurostimulator'' to reflect the 
proposed modifications to MS-DRG assignments. We note that discussion 
of the surgical hierarchy for this proposed modification is discussed 
in section II.C.15. of this proposed rule.
c. Endovascular Cardiac Valve Procedures
    The human heart contains four major valves--the aortic, mitral, 
pulmonary, and tricuspid valves. These valves function to keep blood 
flowing through the heart. When conditions such as stenosis or 
insufficiency/regurgitation occur in one or more of these valves, 
valvular heart disease may result. Intervention options, including 
surgical aortic valve replacement or transcatheter aortic valve 
replacement can be performed to treat diseased or damaged aortic heart 
valves. Surgical aortic valve replacement (SAVR) is a traditional, 
open-chest surgery where an incision is made to access the heart. The 
damaged valve is replaced, and the chest is surgically closed. Since 
SAVR is a major surgery that involves an incision, recovery time tends 
to be longer. Transcatheter aortic valve replacement (TAVR) is a 
minimally invasive procedure that involves a catheter being inserted 
into an artery, without an incision for most cases, and then guided to 
the heart. The catheter delivers the new valve without the need for the 
chest or heart to be surgically opened. Since TAVR is a non-surgical 
procedure, it is generally associated with a much shorter recovery 
time.
    In the FY 2015 IPPS/LTCH PPS final rule (79 FR 49892 through 
49893), we discussed a request we received to create a new MS-DRG that 
would only include the various types of cardiac valve replacements 
performed by an endovascular or transcatheter technique. We reviewed 
the claims data and stated the data analysis showed that cardiac valve 
replacements performed by an endovascular or transcatheter technique 
had a shorter average length of stay and higher average costs in 
comparison to all of the cases in their assigned MS-DRGs, which were 
MS-DRGs 216, 217, 218, 219, 220, and 221 (Cardiac Valve & Other Major 
Cardiothoracic Procedure with and without Cardiac Catheterization, with 
MCC, with CC, and without CC/MCC, respectively). In the FY 2015 IPPS/
LTCH PPS final rule we stated that patients receiving endovascular 
cardiac valve replacements were significantly different from those 
patients who undergo an open chest cardiac valve replacement and noted 
that patients receiving endovascular cardiac valve replacements are not 
eligible for open chest cardiac valve procedures because of a variety 
of health constraints, which we said highlights the fact that peri-
operative complications and post-operative morbidity have significantly 
different profiles for open chest procedures compared with endovascular 
interventions. We further noted that separately grouping these 
endovascular valve replacement procedures provides greater clinical 
cohesion for this subset of high-risk patients. Therefore, we finalized 
our proposal to create MS-DRGs 266 and 267 (Endovascular Cardiac Valve 
Replacement, with MCC and without MCC, respectively) for FY 2015.
    In the FY 2020 IPPS/LTCH PPS final rule (84 FR 42080 through 
42089), we discussed a request we received to modify the MS-DRG 
assignment for transcatheter mitral valve repair (TMVR) with implant 
procedures. We reviewed the claims data and stated based on our data 
analysis, transcatheter cardiac valve repair procedures and 
transcatheter (endovascular) cardiac valve replacement procedures are 
more clinically coherent in that they describe endovascular cardiac 
valve interventions with implants, and were similar in terms of average 
length of stay and average costs to cases in MS-DRGs 266 and 267 when 
compared to other procedures in their current MS-DRG assignment. For 
the reasons described in the rule and after consideration of the public 
comments we received, we finalized our proposal to modify the structure 
of MS-DRGs 266 and 267 by reassigning the procedure codes that describe 
transcatheter cardiac valve repair (supplement) procedures, to revise 
the title of MS-DRG 266 from ``Endovascular Cardiac Valve Replacement 
with MCC'' to ``Endovascular Cardiac Valve Replacement and Supplement 
Procedures with MCC'' and to revise the title of MS-DRG 267 from 
``Endovascular Cardiac Valve Replacement without MCC'' to 
``Endovascular Cardiac Valve Replacement and Supplement Procedures 
without MCC'', to reflect the finalized restructuring.
    For this FY 2025 IPPS/LTCH PPS proposed rule, we received a request 
to delete MS-DRGs 266 and 267 and to move the cases reporting 
transcatheter aortic valve replacement or repair (supplement) 
procedures currently assigned to those MS-DRGs into MS-DRGs 216, 217, 
218, 219, 220, and 221. The requestor asserted that under the current 
IPPS payment methodology, TAVR procedures are not profitable to 
hospitals and when patients are clinically eligible for both a TAVR and 
SAVR procedures, factors beyond clinical appropriateness can drive 
treatment decisions. According to the requestor (the manufacturer of 
the SAPIENTM family of transcatheter heart valves) sharing a 
single set of MS-DRGs would eliminate the current disincentives 
hospitals face and create financial neutrality between the two 
lifesaving treatment options. The requestor stated the current 
disincentives are increasingly problematic because they contribute to 
treatment disparities among certain racial, socioeconomic, and 
geographic groups.
    The requestor noted that currently surgical cardiac valve 
replacement and supplement procedures, such as SAVR, are assigned to 
MS-DRGs 216, 217, 218, 219, 220, and 221, and endovascular cardiac 
valve replacement and supplement procedures, such as TAVR, are assigned 
to MS-DRGs 266 and 267. The requestor stated that both sets of MS-DRGs 
address valve disease and include valve repair or replacement 
procedures for any of the four heart valves. According to the 
requestor, while the sets of MS-DRGs involve clinically similar cases 
their payment rates differ which may be unintentionally influencing 
clinical decision-making by incentivizing hospitals to choose more 
invasive SAVR

[[Page 35963]]

procedures over less-invasive TAVR procedures.
    As mentioned earlier, the requestor recommended that CMS delete MS-
DRGs 266 and 267 and move the cases reporting transcatheter aortic 
valve replacement or repair (supplement) procedures currently assigned 
to those MS-DRGs into MS-DRGs 216, 217, 218, 219, 220, and 221. The 
requestor performed their own analysis and stated that their models of 
this suggested solution indicated the change would result in moderate 
differences in per case payments by case type and would not increase 
overall Medicare spending. The requestor noted that while their 
requested solution would potentially decrease payment to cases 
currently assigned to MS-DRGs 216, 217, 218, 219, 220, and 221, while 
at the same time increasing the payment to cases reporting endovascular 
cardiac valve replacement and supplement procedures, the results of 
their claim analysis demonstrated that the net difference in total 
payments across all cases would increase by approximately $6.5 million. 
The requestor stated that they anticipate that their proposed solution 
could increase Medicare patients' access to innovative endovascular 
cardiac valve procedures by establishing payment neutrality between 
SAVR and TAVR procedures.
    We reviewed this request and note the requestor is correct that in 
Version 41.1 cases reporting procedure codes that describe endovascular 
cardiac valve replacement and supplement procedures, including TAVR, 
group to MS-DRGs 266 and 267. The requestor is also correct that cases 
reporting procedure codes that describe surgical cardiac valve 
replacement and supplement procedures, including SAVR, group to MS-DRGs 
216, 217, 218, 219, 220, and 221. We refer the reader to the ICD-10 MS-
DRG Definitions Manual Version 41.1 (available on the CMS website at: 
https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps/ms-drg-classifications-and-software) for complete 
documentation of the GROUPER logic for MS-DRGs 216, 217, 218, 219, 220, 
221, 266 and 267.
    To begin our analysis, we identified the ICD-10-PCS procedure codes 
that describe endovascular (transcatheter) cardiac valve replacement 
and supplement procedures and the ICD-10-PCS procedure codes that 
describe surgical cardiac valve replacement and supplement procedures. 
We also identified the ICD-10-PCS codes that describe cardiac 
catheterization, as MS-DRGs 216, 217, and 218 (Cardiac Valve and Other 
Major Cardiothoracic Procedures with Cardiac Catheterization with MCC, 
with CC, and without CC/MCC, respectively) are defined by the 
performance of cardiac catheterization. We refer the reader to Table 
6P.2a, Table 6P.2b, and Table 6P.2c, respectively, associated with this 
proposed rule (and available at: https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps) for the lists of the 
ICD-10-PCS procedure codes that we identified that describe 
endovascular cardiac valve replacement and supplement procedures, 
surgical cardiac valve replacement and supplement procedures, and 
cardiac catheterization procedures.
    We then examined the claims data from the September 2023 update of 
the FY 2023 MedPAR file for all cases in MS-DRGs 216, 217, 218, 219, 
220, and 221 and compared the results to cases reporting surgical 
cardiac valve replacement and supplement procedures in MS-DRG 216, 217, 
218, 219, 220, and 221. The following table shows our findings:
[GRAPHIC] [TIFF OMITTED] TP02MY24.014

    As shown in the table, in MS-DRG 216, we identified a total of 
5,033 cases with an average length of stay of 13.9 days and average 
costs of $84,176. Of those 5,033 cases, there were 2,973 cases 
reporting surgical cardiac valve replacement and supplement procedures, 
with average costs higher than the average costs in the FY 2023 MedPAR 
file for MS-DRG 216 ($87,497 compared to $84,176) and a longer average 
length of stay (16.8 days

[[Page 35964]]

compared to 13.9 days). In MS-DRG 217, we identified a total of 1,635 
cases with an average length of stay of 7.2 days and average costs of 
$58,381. Of those 1,635 cases, there were 867 cases reporting surgical 
cardiac valve replacement and supplement procedures, with average costs 
lower than the average costs in the FY 2023 MedPAR file for MS-DRG 217 
($56,829 compared to $58,381) and a longer average length of stay (9.5 
days compared to 7.2 days). In MS-DRG 218, we identified a total of 275 
cases with an average length of stay of 3.4 days and average costs of 
$54,624. Of those 275 cases, there were 60 cases reporting surgical 
cardiac valve replacement and supplement procedures, with average costs 
lower than the average costs in the FY 2023 MedPAR file for MS-DRG 218 
($45,096 compared to $54,624) and a longer average length of stay (6.7 
days compared to 3.4 days). In MS-DRG 219, we identified a total of 
12,458 cases with an average length of stay of 10.5 days and average 
costs of $67,228. Of those 12,458 cases, there were 9,780 cases 
reporting surgical cardiac valve replacement and supplement procedures, 
with average costs lower than the average costs in the FY 2023 MedPAR 
file for MS-DRG 219 ($64,954 compared to $67,228), and a slightly 
shorter average length of stay (10.3 days compared to 10.5 days). In 
MS-DRG 220, we identified a total of 9,829 cases with an average length 
of stay of 6.3 days and average costs of $47,242. Of those 9,829 cases, 
there were 7,841 cases reporting surgical cardiac valve replacement and 
supplement procedures, with average costs lower than the average costs 
in the FY 2023 MedPAR file for MS-DRG 220 ($46,245 compared to $47,242) 
and a slightly longer average length of stay (6.4 days compared to 6.3 
days). In MS-DRG 221, we identified a total of 1,242 cases with an 
average length of stay of 3.8 days and average costs of $41,539. Of 
those 1,242 cases, there were 627 cases reporting surgical cardiac 
valve replacement and supplement procedures, with average costs lower 
than the average costs in the FY 2023 MedPAR file for MS-DRG 221 
($39,081 compared to $41,539) and a longer average length of stay (4.9 
days compared to 3.8 days).
    Next, we examined claims data from the September 2023 update of the 
FY 2023 MedPAR file for MS-DRGs 266 and 267. Our findings are shown in 
the following table.
[GRAPHIC] [TIFF OMITTED] TP02MY24.015

    Because there is a two-way split within MS-DRGs 266 and 267 and 
there is a three-way split within MS-DRGs 216, 217, and 218, and MS-
DRGs 219, 220, and 221 (Cardiac Valve and Other Major Cardiothoracic 
Procedures without Cardiac Catheterization with MCC, with CC, and 
without CC/MCC, respectively), we also analyzed the cases reporting a 
code describing an endovascular cardiac valve replacement and 
supplement procedure with a procedure code describing the performance 
of a cardiac catheterization for the presence or absence of a secondary 
diagnosis designated as a complication or comorbidity (CC) or a major 
complication or comorbidity (MCC). We also analyzed the cases reporting 
a code describing an endovascular cardiac valve replacement and 
supplement procedure without a procedure code describing the 
performance of a cardiac catheterization for the presence or absence of 
a secondary diagnosis designated as a CC or an MCC.
[GRAPHIC] [TIFF OMITTED] TP02MY24.016

    As shown in the table, the data analysis performed indicates that 
the 5,443 cases in MS-DRG 266 reporting endovascular cardiac valve 
replacement and supplement procedures with a procedure code describing 
the

[[Page 35965]]

performance of a cardiac catheterization, and with a secondary 
diagnosis code designated as an MCC have an average length of stay that 
is shorter than the average length of stay (7.9 days versus 16.8 days) 
and lower average costs ($63,128 versus $87,497) when compared to the 
cases in MS-DRG 216 reporting surgical cardiac valve replacement and 
supplement procedures with a procedure code describing the performance 
of a cardiac catheterization, and with a secondary diagnosis code 
designated as an MCC. The 4,761 cases in MS-DRG 267 reporting 
endovascular cardiac valve replacement and supplement procedures with a 
procedure code describing the performance of a cardiac catheterization, 
and with a secondary diagnosis code designated as a CC have an average 
length of stay that is shorter than the average length of stay (2 days 
versus 9.5 days) and lower average costs ($42,163 versus $56,829) when 
compared to the cases in MS-DRG 217 reporting surgical cardiac valve 
replacement and supplement procedures with a procedure code describing 
the performance of a cardiac catheterization, and with a secondary 
diagnosis code designated as an CC. The 1,386 cases in MS-DRG 267 
reporting endovascular cardiac valve replacement and supplement 
procedures with a procedure code describing the performance of a 
cardiac catheterization, and without a secondary diagnosis code 
designated as a CC or MCC have an average length of stay that is 
shorter than the average length of stay (1.3 days versus 6.7 days) and 
lower average costs ($39,709 versus $45,096) when compared to the cases 
in MS-DRG 218 reporting surgical cardiac valve replacement and 
supplement procedures with a procedure code describing the performance 
of a cardiac catheterization, without a secondary diagnosis code 
designated as a CC or MCC.
    The 14,493 cases in MS-DRG 266 reporting endovascular cardiac valve 
replacement and supplement procedures without a procedure code 
describing the performance of a cardiac catheterization, and with a 
secondary diagnosis code designated as an MCC have an average length of 
stay that is shorter than the average length of stay (3.5 days versus 
10.3 days) and lower average costs ($50,831 versus $64,954) when 
compared to the cases in MS-DRG 219 reporting surgical cardiac valve 
replacement and supplement procedures without a procedure code 
describing the performance of a cardiac catheterization, and with a 
secondary diagnosis code designated as an MCC. The 22,996 cases in MS-
DRG 267 reporting endovascular cardiac valve replacement and supplement 
procedures without a procedure code describing the performance of a 
cardiac catheterization, and with a secondary diagnosis code designated 
as a CC have an average length of stay that is shorter than the average 
length of stay (1.5 days versus 6.4 days) and lower average costs 
($43,637 versus $46,245) when compared to the cases in MS-DRG 220 
reporting surgical cardiac valve replacement and supplement procedures 
without a procedure code describing the performance of a cardiac 
catheterization, and with a secondary diagnosis code designated as an 
CC. The 7,522 cases in MS-DRG 267 reporting endovascular cardiac valve 
replacement and supplement procedures without a procedure code 
describing the performance of a cardiac catheterization, and without a 
secondary diagnosis code designated as a CC or MCC have an average 
length of stay that is shorter than the average length of stay (1.2 
days versus 4.9 days) and higher average costs ($42,472 versus $39,081) 
when compared to the cases in MS-DRG 221 reporting surgical cardiac 
valve replacement and supplement procedures without a procedure code 
describing the performance of a cardiac catheterization, without a 
secondary diagnosis code designated as a CC or MCC.
    This data analysis shows the cases in MS-DRG 266 and 267 reporting 
endovascular cardiac valve replacement and supplement procedures with a 
procedure code describing the performance of a cardiac catheterization 
when distributed based on the presence or absence of a secondary 
diagnosis designated as a CC or a MCC have average costs lower than the 
average costs of cases reporting surgical cardiac valve replacement and 
supplement procedures with a procedure code describing the performance 
of a cardiac catheterization in the FY 2023 MedPAR file for MS-DRGs 
216, 217, and 218 respectively, and the average lengths of stay are 
shorter. Similarly, the cases in MS-DRG 266 and 267 reporting 
endovascular cardiac valve replacement and supplement procedures 
without a procedure code describing the performance of a cardiac 
catheterization when distributed based on the presence or absence of a 
secondary diagnosis designated as a CC or a MCC generally have average 
costs lower than the average costs of cases reporting surgical cardiac 
valve replacement and supplement procedures without a procedure code 
describing the performance of a cardiac catheterization in the FY 2023 
MedPAR file for MS-DRGs 219, 220, and 221 respectively, and the average 
lengths of stay are shorter.
    For patients with an indication for cardiac valve replacement, 
clinical and anatomic factors must be considered when decision-making 
between procedures such as TAVR and SAVR. We note that SAVR is not a 
treatment option for patients with extreme surgical risk (that is, high 
probability of death or serious irreversible complication), severe 
atheromatous plaques of the ascending aorta such that aortic cross-
clamping is not feasible, or with other conditions that would make 
operation through sternotomy or thoracotomy prohibitively hazardous. We 
agree that the endovascular or transcatheter technique presents a 
viable option for high-risk patients who are not candidates for the 
traditional open surgical approach, however we also note that TAVR is 
not indicated for every patient. TAVR is contraindicated in patients 
who cannot tolerate an anticoagulation/antiplatelet regimen, or who 
have active bacterial endocarditis or other active infections, or who 
have significant annuloplasty ring dehiscence.
    We have concern with the assertion that clinicians perform more 
invasive surgical procedures, such as SAVR procedures, only to increase 
payment to their facility where minimally invasive TAVR procedures are 
also viable option. The choice of SAVR versus TAVR should not be based 
on potential facility payment. Instead, the decision on the procedural 
approach to be utilized should be based upon an individualized risk-
benefit assessment that includes reviewing factors such as the 
patient's age, surgical risk, frailty, valve morphology, and presence 
of concomitant valve disease or coronary artery disease. As we have 
stated in prior rulemaking (83 FR 41201), it is not appropriate for 
facilities to deny treatment to beneficiaries needing a specific type 
of therapy or treatment that involves increased costs. Conversely, it 
is not appropriate for facilities to recommend a specific type of 
therapy or treatment strictly because it may involve higher payment to 
the facility.
    Also, we have concern with the requestor's assertion that sharing a 
single set of MS-DRGs could eliminate any perceived disincentives 
hospitals may face and create financial neutrality between the two 
lifesaving treatment options. Data analysis shows that cases reporting 
surgical cardiac valve

[[Page 35966]]

replacement and supplement procedures have higher costs and longer 
lengths of stay. If clinical decision-making is being driven by 
financial motivations, as suggested by the requestor, in circumstances 
where the decision on which approach is best (for example, TAVR or 
SAVR) is left to the providers' discretion, it is unclear how reducing 
payment for surgical cardiac valve replacement and supplement 
procedures would eliminate possible disincentives, or not have the 
opposite effect, and instead incentivize endovascular cardiac valve 
replacement and supplement procedures.
    The MS-DRGs are a classification system intended to group together 
diagnoses and procedures with similar clinical characteristics and 
utilization of resources and are not intended to be utilized as a tool 
to incentivize the performance of certain procedures. When performed, 
surgical cardiac valve replacement and supplement procedures are 
clinically different from endovascular cardiac valve replacement and 
supplement procedures in terms of technical complexity and hospital 
resource use. In the FY 2015 IPPS/LTCH PPS final rule, we stated that 
separately grouping endovascular valve replacement procedures provides 
greater clinical cohesion for this subset of high-risk patients. Our 
claims analysis for this FY 2025 IPPS/LTCH PPS proposed rule 
demonstrates that this continues to be substantiated by the difference 
in average costs and average lengths of stay demonstrated by the two 
cohorts. We continue to believe that endovascular cardiac valve 
replacement and supplement procedures are clinically coherent in their 
currently assigned MS-DRGs. Therefore, we are proposing to maintain the 
structure of MS-DRGs 266 and 267 for FY 2025.
d. MS-DRG Logic for MS-DRG 215
    We received a request to review the GROUPER logic for MS-DRG 215 
(Other Heart Assist System Implant) in MDC 05 (Diseases and Disorders 
of the Circulatory System). The requestor stated that when the 
procedure code describing the revision of malfunctioning devices within 
the heart via an open approach is assigned, the encounter groups to MS-
DRG 215. The requestor stated that, in their observation, ICD-10-PCS 
code 02WA0JZ (Revision of synthetic substitute in heart, open approach) 
can only be assigned if a more specific anatomical site is not 
documented in the operative note. The requestor further stated they 
interpreted this to mean that an ICD-10-PCS procedure code describing 
the open revision of a synthetic substitute in the heart can only apply 
to the ventricular wall or left atrial appendage and excludes the 
atrial or ventricular septum or any valve to qualify for MS-DRG 215 and 
recommended that CMS consider the expansion of the open revision of 
heart structures to include the atrial or ventricular septum and heart 
valves.
    To begin our analysis, we reviewed the GROUPER logic. The requestor 
is correct that ICD-10-PCS procedure code 02WA0JZ is currently one of 
the listed procedure codes in the GROUPER logic for MS-DRG 215. While 
the requestor stated that when procedures codes describing the 
revisions of malfunctioning devices within the heart via an open 
approach are assigned, the encounter groups to MS-DRG 215, we wish to 
clarify that the revision codes listed in the GROUPER logic for MS-DRG 
215 specifically describe procedures to correct, to the extent 
possible, a portion of a malfunctioning heart assist device or the 
position of a displaced heart assist device. Further, it is unclear 
what is meant by the requestor's statement that ICD-10-PCS code 02WA0JZ 
can only be assigned if more specific anatomical site is not documented 
in the operative note, as ICD-10-PCS code 02WA0JZ is used to describe 
the open revision of artificial heart systems. Total artificial hearts 
are pulsating bi-ventricular devices that are implanted into the chest 
to replace a patient's left and right ventricles and can provide a 
bridge to heart transplantation for patients who have no other 
reasonable medical or surgical treatment options. We refer the reader 
to the ICD-10 MS-DRG Definitions Manual Version 41.1 (available on the 
CMS website at: https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps/ms-drg-classifications-and-software) for complete documentation of the GROUPER logic for MS-DRG 
215. We encourage the requestor and any providers that have cases 
involving heart assist devices for which they need ICD-10 coding 
assistance and clarification on the usage of the codes, to submit their 
questions to the American Hospital Association's Central Office on ICD-
10 at https://www.codingclinicadvisor.com/.
    As previously noted, the requestor recommended that we consider 
expansion of the open revision of heart structures to include the 
atrial or ventricular septum and heart valves. The requestor did not 
provide a specific list of procedure codes involving the open revision 
of heart structures. While not explicitly stated, we understood this 
request to be for our consideration of the reassignment of the 
procedure codes describing the open revision of devices in the heart 
valves, atrial septum, or ventricular septum to MS-DRG 215, therefore, 
we reviewed the ICD-10-PCS classification and identified the following 
18 procedure codes. These 18 codes are all assigned to MS-DRGs 228 and 
229 (Other Cardiothoracic Procedures with and without MCC, 
respectively) in MDC 05 in Version 41.1.

[[Page 35967]]

[GRAPHIC] [TIFF OMITTED] TP02MY24.017

    Next, we examined claims data from the September 2023 update of the 
FY 2023 MedPAR file for MS-DRG 228 and 229 to identify cases reporting 
one of the 18 codes listed previously that describe the open revision 
of devices in the heart valves, atrial septum, or ventricular septum. 
Our findings are shown in the following table:
[GRAPHIC] [TIFF OMITTED] TP02MY24.018

    As shown in the table, in MS-DRG 228, we identified a total of 
4,391 cases with an average length of stay of 8.7 days and average 
costs of $44,565. Of those 4,391 cases, there were 12 cases reporting a 
procedure code describing the open revision of devices in the heart 
valves, atrial septum, or ventricular septum, with average costs higher 
than the average costs in the FY 2023 MedPAR file for MS-DRG 228 
($51,549 compared to $44,565) and a longer average length of stay (15.7 
days compared to 8.7 days). In MS-DRG 229, we identified a total of 
5,712 cases with an average length of stay of 3.3 days and average 
costs of $28,987. Of those 5,712 cases, there was one case reporting a 
procedure code describing the open revision of devices in the heart 
valves, atrial septum, or ventricular septum with costs lower than the 
average costs in the FY 2023 MedPAR file for MS-DRG 229 ($11,322 
compared to $28,987) and a shorter length of stay (1 day compared to 
3.3 days).
    We then examined claims data from the September 2023 update of the 
FY 2023 MedPAR for MS-DRG 215. Our findings are shown in the following 
table.
[GRAPHIC] [TIFF OMITTED] TP02MY24.019

    Our analysis indicates that the cases assigned to MS-DRG 215 have 
much higher average costs than the cases reporting a procedure code 
describing the open revision of devices in the heart valves, atrial 
septum, or ventricular septum currently assigned to MS-DRGs 228 and 
229. Instead, the average costs and average length of stay for case 
reporting a procedure code describing the open revision of devices in 
the heart valves, atrial septum, or ventricular septum appear to be 
generally more aligned with the average costs and average length of 
stay for all cases in MS-DRGs 228 and 229, where they are currently 
assigned.
    In addition, based on our review of the clinical considerations, we 
do not believe the procedure codes describing the open revision of 
devices in the heart valves, atrial septum, or ventricular septum are 
clinically coherent with the procedure codes currently assigned to MS-
DRG 215. Heart assist devices, such as ventricular assist devices and 
artificial heart systems, provide circulatory support by taking over 
most of the workload of the left ventricle. Blood enters the pump 
through an

[[Page 35968]]

inflow conduit connected to the left ventricle and is ejected through 
an outflow conduit into the body's arterial system. Heart assist 
devices can provide temporary left, right, or biventricular support for 
patients whose hearts have failed and can also be used as a bridge for 
patients who are awaiting a heart transplant. Devices placed in the 
heart valves, atrial septum, or ventricular septum do not serve the 
same purpose as heart assist devices and we do not believe the 
procedure codes describing the revision of these devices should be 
assigned to MS-DRG 215. Further, the various indications for devices 
placed in the heart valves, atrial septum or ventricular septum are not 
aligned with the indications for heart assist devices. We believe that 
patients with indications for heart assist devices tend to be more 
severely ill and these inpatient admissions are associated with greater 
resource utilization. Therefore, for the reasons stated previously, we 
are proposing to maintain the GROUPER logic for MS-DRG 215 for FY 2025.
5. MDC 06 (Diseases and Disorders of the Digestive System): Excision of 
Intestinal Body Parts
    We identified a replication issue from the ICD-9 based MS-DRGs to 
the ICD-10 based MS-DRGs regarding the assignment of eight ICD-10-PCS 
codes that describe the excision of intestinal body parts by open, 
percutaneous, or percutaneous endoscopic approach. Under the Version 32 
ICD-9 based MS-DRGs, ICD-9-CM procedure code 45.33 (Local excision of 
lesion or tissue of small intestine, except duodenum) was designated as 
an O.R. procedure and was assigned to MDC 06 (Diseases and Disorders of 
the Digestive System) in MS-DRGs 347, 348, and 349 (Anal and Stomal 
Procedures with MCC, with CC, and without CC/MCC, respectively).
    There are eight ICD-10-PCS code translations that provide more 
detailed and specific information for ICD-9-CM code 45.33 that also 
currently group to MS-DRGs 347, 348, and 349 in the ICD-10 MS-DRGs 
Version 41.1. These eight procedure codes are shown in the following 
table:
[GRAPHIC] [TIFF OMITTED] TP02MY24.020

    We noted during our review of this issue that under ICD-9-CM, 
procedure code 45.33 did not differentiate the specific type of 
approach used to perform the procedure. This is in contrast to the 
eight comparable ICD-10-PCS code translations listed in the previous 
table that do differentiate among various approaches (open, 
percutaneous, and percutaneous endoscopic). We also noted that there 
are four additional ICD-10-PCS code translations that provide more 
detailed and specific information for ICD-9-CM code 45.33, however 
these four codes currently group to MS-DRGs 329, 330, and 331 (Major 
Small and Large Bowel Procedures with MCC, with CC, and without CC/MCC, 
respectively), and not MS-DRGs 347, 348, and 349, in the ICD-10 MS-DRGs 
Version 41.1. These four procedure codes are shown in the following 
table:
[GRAPHIC] [TIFF OMITTED] TP02MY24.021

    We refer the reader to the ICD-10 MS-DRG Definitions Manual Version 
41.1 (available on the CMS website at: https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps/ms-drg-classifications-and-software) for complete documentation of the GROUPER 
logic for MS-DRGs 329, 330, 331, 347, 348, and 349.
    Next, we examined claims data from the September 2023 update of the 
FY 2023 MedPAR file for MS-DRG 347, 348, and 349 to identify cases 
reporting one of the eight codes listed previously that describe 
excision of intestinal body parts by an open, percutaneous, or 
percutaneous endoscopic approach. Our findings are shown in the 
following table:

[[Page 35969]]

[GRAPHIC] [TIFF OMITTED] TP02MY24.022

    As shown in the table, in MS-DRG 347, we identified a total of 752 
cases with an average length of stay of 7.6 days and average costs of 
$21,462. Of those 752 cases, there were 66 cases reporting one of eight 
procedure codes describing the excision of intestinal body parts by an 
open, percutaneous, or percutaneous endoscopic approach, with average 
costs higher than the average costs in the FY 2023 MedPAR file for MS-
DRG 347 ($27,081 compared to $21,462) and a longer average length of 
stay (8.5 days compared to 7.6 days). In MS-DRG 348, we identified a 
total of 1,580 cases with an average length of stay of 4.2 days and 
average costs of $12,020. Of those 1,580 cases, there were 192 cases 
reporting one of eight procedure codes describing the excision of 
intestinal body parts by an open, percutaneous, or percutaneous 
endoscopic approach, with average costs higher than the average costs 
in the FY 2023 MedPAR file for MS-DRG 348 ($17,063 compared to $12,020) 
and a longer average length of stay (4.9 days compared to 4.2 days). In 
MS-DRG 349, we identified a total of 644 cases with an average length 
of stay of 2.2 days and average costs of $9,095. Of those 644 cases, 
there were 117 cases reporting one of eight procedure codes describing 
the excision of intestinal body parts by an open, percutaneous, or 
percutaneous endoscopic approach, with average costs higher than the 
average costs in the FY 2023 MedPAR file for MS-DRG 349 ($14,612 
compared to $9,095), and a longer average length of stay (3 days 
compared to 2.2 days).
    We then examined claims data from the September 2023 update of the 
FY 2023 MedPAR for MS-DRGs 329, 330, and 331. Our findings are shown in 
the following table.
[GRAPHIC] [TIFF OMITTED] TP02MY24.023

    While the average costs for all cases in MS-DRGs 329, 330, and 331 
are higher than the average costs of the cases reporting one of eight 
procedure codes describing the excision of intestinal body parts by an 
open, percutaneous, or percutaneous endoscopic approach, the data 
suggest that overall, cases reporting one of eight procedure codes 
describing the excision of intestinal body parts by an open, 
percutaneous, or percutaneous endoscopic approach may be more 
appropriately aligned with the average costs of the cases in MS-DRGs 
329, 330, and 331 in comparison to MS-DRGs 347, 348, and 349, even 
though the average lengths of stay are shorter.
    We reviewed this grouping issue, and our analysis indicates that 
the eight procedure codes describing the excision of intestinal body 
parts by an open, percutaneous, or percutaneous endoscopic approach 
were initially assigned to the list of procedures in the GROUPER logic 
for MS-DRGs 347, 348, and 349 as a result of replication in the 
transition from ICD-9 to ICD-10 based MS-DRGs. We also note that 
procedure codes 0DB83ZZ, 0DBA3ZZ, 0DBA4ZZ, 0DBB3ZZ, 0DBB4ZZ, 0DBC0ZZ, 
0DBC3ZZ, and 0DBC4ZZ do not describe procedures on a stoma, which is an 
artificial opening on the abdomen that can be connected to either the 
digestive or urinary system to allow waste to be diverted out of the 
body, or the anus. We support the reassignment of codes 0DB83ZZ, 
0DBA3ZZ, 0DBA4ZZ, 0DBB3ZZ, 0DBB4ZZ, 0DBC0ZZ, 0DBC3ZZ, and 0DBC4ZZ for 
clinical coherence and believe these eight procedure codes should be 
appropriately grouped along with the four other procedure codes that 
describe excision of intestinal body parts by an open, or percutaneous 
endoscopic approach currently assigned to MS-DRGs 329, 330, and 331.
    Accordingly, because the procedures described by the eight 
procedure codes that describe excision of intestinal body parts by an 
open, percutaneous, or percutaneous endoscopic approach are not 
clinically consistent with procedures on the anus or stoma, and it is 
clinically appropriate to reassign these procedures to be consistent 
with the four other procedure codes that describe excision of 
intestinal body parts by an open, or percutaneous endoscopic approach 
in MS-DRGs 329, 330, and 331, we are proposing the reassignment of 
procedure codes 0DB83ZZ, 0DBA3ZZ, 0DBA4ZZ, 0DBB3ZZ, 0DBB4ZZ, 0DBC0ZZ, 
0DBC3ZZ, and 0DBC4ZZ from MS-DRGs 347, 348, and 349 (Anal and Stomal 
Procedures with MCC, with CC, and without CC/MCC, respectively) to MS-
DRGs 329, 330, and 331 (Major Small and Large Bowel Procedures with 
MCC, with CC, and without CC/MCC, respectively) in MDC 06, effective FY 
2025.

6. MDC 08 (Diseases and Disorders of the Musculoskeletal System and 
Connective Tissue)
a. MS-DRG Logic for MS-DRGs 456, 457, and 458
    We identified an inconsistency in the GROUPER logic for MS-DRGs 
456, 457, and 458 (Spinal Fusion Except Cervical with Spinal Curvature, 
Malignancy, Infection or Extensive Fusions with MCC, with CC, and 
without CC/MCC, respectively) related to ICD-10-CM diagnosis codes 
describing deforming dorsopathies. The logic for case assignment to MS-
DRGs 456, 457, and 458 as displayed in the ICD-10 MS-DRG Definitions 
Manual Version 41.1 (which is available on the CMS website at: https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/MS-DRG-Classifications-and-Software) is comprised of 
four logic lists. The first logic list is entitled ``Spinal Fusion 
Except Cervical'' and is defined by a list of procedure codes 
designated as O.R. procedures that describe spinal fusion procedures of 
the thoracic, thoracolumbar, lumbar, lumbosacral, sacrococcygeal, 
coccygeal, and sacroiliac joint. The second logic list is entitled 
``Spinal Curvature/Malignancy/Infection'' and is defined by a list of 
diagnosis codes describing spinal curvature, spinal malignancy, and 
spinal infection that are used to define the logic for case assignment 
when any one of the listed diagnosis codes is reported as the principal 
diagnosis. The third logic list is entitled ``OR Secondary Diagnosis'' 
and is defined by a list of diagnosis codes describing curvature of the 
spine that are used to define the logic for case assignment when any 
one of the listed codes is reported as a secondary diagnosis. The 
fourth logic list is entitled ``Extensive Fusions'' and is defined by a 
list of procedure codes designated as O.R. procedures that describe 
extensive spinal fusion procedures. We refer the reader to the ICD-10 
MS-DRG Definitions Manual Version 41.1, (available on the CMS website 
at: https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps/ms-drg-classifications-and-software) for complete 
documentation of the GROUPER logic for MS-DRGs 456, 457, and 458.
    In the second logic list entitled ``Spinal Curvature/Malignancy/
Infection'' there are a subset of six diagnosis codes describing other 
specified deforming dorsopathies as shown in the following table.
[GRAPHIC] [TIFF OMITTED] TP02MY24.024

    In the third logic list entitled ``OR Secondary Diagnosis'' there 
are currently 14 diagnosis codes listed, one of which is diagnosis code 
M43.8X9 (Other specified deforming dorsopathies, site unspecified) as 
shown in the following table.
[GRAPHIC] [TIFF OMITTED] TP02MY24.025

    We recognized that the five diagnosis codes describing deforming 
dorsopathies of specific anatomic sites that are listed in the second 
logic list entitled ``Spinal Curvature/Malignancy/Infection'' are not 
listed in the third logic list entitled ``OR Secondary Diagnosis'', 
rather, only diagnosis code M43.8X9 (Other specified deforming 
dorsopathies, site unspecified) appears in both logic lists. Therefore, 
we considered if it was clinically appropriate to add the five 
diagnosis codes describing deforming dorsopathies of specific anatomic 
sites that are listed in the second logic list entitled ``Spinal 
Curvature/Malignancy/Infection'' to the third logic list entitled ``OR 
Secondary Diagnosis''.
    A deforming dorsopathy is characterized by abnormal bending or 
flexion in the vertebral column. All spinal deformities involve 
problems with curve or rotation of the spine, regardless of site 
specificity. We believe the five diagnosis codes describing deforming 
dorsopathies of specific anatomic sites to be clinically aligned with 
the diagnosis codes currently

[[Page 35971]]

included in the ``OR Secondary Diagnosis'' logic list. Therefore, for 
clinical consistency we are proposing to add diagnosis codes M43.8X4, 
M43.8X5, M43.8X6, M43.8X7, and M43.8X8 to the ``OR Secondary 
Diagnosis'' logic list for MS-DRGs 456, 457, and 458, effective October 
1, 2024 for FY 2025.
b. Interbody Spinal Fusion Procedures
    In the FY 2024 IPPS/LTCH PPS proposed rule (88 FR 26726 through 
26729) and final rule (88 FR 58731 through 58735, as corrected in the 
FY 2024 final rule correction notice at 88 FR 77211), we discussed a 
request we received to reassign cases reporting spinal fusion 
procedures using an aprevoTM customized interbody fusion 
device from the lower severity MS-DRG 455 (Combined Anterior and 
Posterior Spinal Fusion without CC/MCC) to the higher severity MS-DRG 
453 (Combined Anterior and Posterior Spinal Fusion with MCC), from the 
lower severity MS-DRG 458 (Spinal Fusion Except Cervical with Spinal 
Curvature, Malignancy, Infection or Extensive Fusions without CC/MCC) 
to the higher severity level MS-DRG 456 (Spinal Fusion Except Cervical 
with Spinal Curvature, Malignancy, Infection or Extensive Fusions with 
MCC) when a diagnosis of malalignment is reported, and from MS-DRGs 459 
and 460 (Spinal Fusion Except Cervical with MCC and without MCC, 
respectively) to MS-DRG 456. We refer the reader to the ICD-10 MS-DRG 
Definitions Manual Version 41.1 (available on the CMS website at: 
https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps/ms-drg-classifications-and-software) for complete 
documentation of the GROUPER logic.
    We also noted that the aprevoTM Intervertebral Body 
Fusion Device technology was approved for new technology add-on 
payments for FY 2022 (86 FR 45127 through 45133). We further noted 
that, as discussed in the FY 2023 IPPS/LTCH PPS final rule (87 FR 49468 
through 49469), CMS finalized the continuation of the new technology 
add-on payments for this technology for FY 2023. In the FY 2024 IPPS/
LTCH PPS final rule (88 FR 58802), we finalized the continuation of new 
technology add-on payments for the transforaminal lumbar interbody 
fusion (TLIF) indication for aprevoTM for FY 2024, and the 
discontinuation of the new technology add-on payments for the anterior 
lumbar interbody fusion (ALIF) and lateral lumbar interbody fusion 
(LLIF) indications for FY 2024. We refer the reader to section II.E. 
for discussion of the FY 2025 status of technologies receiving new 
technology add-on payments for FY 2024, including the status for the 
aprevoTM technology.
    As also discussed in the FY 2024 IPPS/LTCH PPS proposed rule (88 FR 
26726 through 26729) and final rule (88 FR 58731 through 58735), 
effective October 1, 2021 (FY 2022), we implemented 12 new ICD-10-PCS 
procedure codes to identify and describe spinal fusion procedures using 
the aprevoTM customized interbody fusion device. In the 
proposed rule we noted that the manufacturer expressed concerns that 
there may be unintentional miscoded claims from providers with whom 
they do not have an explicit relationship and that following the 
submission of the request for the FY 2024 MS-DRG classification change 
for cases reporting the performance of a spinal fusion procedure 
utilizing an aprevoTM customized interbody spinal fusion 
device, it submitted a code proposal requesting a revision to the title 
of the procedure codes that were finalized effective FY 2022. As 
discussed in the FY 2024 IPPS/LTCH PPS final rule, a proposal to revise 
the code title for the procedure codes that identify and describe 
spinal fusion procedures using the aprevoTM customized 
interbody fusion device was presented and discussed as an Addenda item 
at the March 7-8, 2023 ICD-10 Coordination and Maintenance Committee 
meeting and subsequently finalized.
    The code title changes for the 12 ICD-10-PCS procedure codes to 
identify and describe spinal fusion procedures using the 
aprevoTM customized interbody fusion device were reflected 
in the FY 2024 ICD-10-PCS Code Update files available via the CMS 
website at: https://www.cms.gov/medicare/coding-billing/icd-10-codes/2024-icd-10-pcs, as well as in Table 6F.--Revised Procedure Code 
Titles--FY 2024 associated with the FY 2024 IPPS/LTCH PPS final rule 
and available via the CMS website at: https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps. We note that 
only the code titles were revised and the code numbers themselves did 
not change.
    Accordingly, effective with discharges on and after October 1, 2023 
(FY 2024), the 12 ICD-10-PCS procedure codes to identify and describe 
spinal fusion procedures using the aprevoTM customized 
interbody fusion device with their revised code titles are as follows:

    As discussed in the FY 2024 proposed and final rules, as part of 
our analysis of the manufacturer's request to reassign cases involving 
the aprevoTM device, we presented findings from our analysis 
of claims data from the September 2022 update of the FY 2022 MedPAR 
file for MS-DRGs 453, 454, 455, 456, 457, 458, 459, and 460 and cases 
reporting any one of the 12 original procedure codes describing 
utilization of an aprevoTM customized interbody spinal 
fusion device. We stated that while we agreed that the findings from 
our analysis appeared to indicate that cases reporting the performance 
of a procedure using an aprevoTM customized interbody spinal 
fusion device reflected a higher consumption of resources, due to the 
concerns expressed with respect to suspected inaccuracies of the coding 
and therefore, reliability of the claims data, we would continue to 
monitor the claims data for resolution of the potential coding issues 
identified by the requestor (the manufacturer). We stated that we 
continued to believe additional review of claims data was warranted and 
would be informative as we continued to consider cases involving this 
technology for future rulemaking. Specifically, we stated we believed 
it would be premature to propose any MS-DRG modifications for spinal 
fusion procedures using an aprevoTM customized interbody 
spinal fusion device for FY 2024 and finalized our proposal to maintain 
the structure of MS-DRGs 453, 454, 455, 456, 457, 458, 459, and 460, 
without modification, for FY 2024 (88 FR 58734 through 58735). As 
discussed further in the FY 2024 final rule correction, in response to 
the manufacturer's comment expressing concern about the reliability of 
the Medicare claims data in the MedPAR file used for purposes of CMS's 
claims data analysis, as compared to the manufacturer's analysis of its 
own customer claims data, we stated that in order for us to consider 
using non-MedPAR data, the non-MedPAR data must be independently 
validated, meaning when an entity submits non-MedPAR data, we must be 
able to independently review the medical records and verify that a 
particular procedure was performed for each of the cases that 
purportedly involved the procedure. We noted that, in this particular 
circumstance, where external data for cases reporting the use of an 
aprevoTM spinal fusion device was provided, we did not have 
access to the medical records to conduct an independent review; 
therefore, we were not able to validate or confirm the non-MedPAR data 
submitted by the commenter for consideration in FY 2024. However, we 
also noted that our work in this area was ongoing, and we would 
continue to examine the data and consider these issues as we develop 
potential future rulemaking proposals. We refer readers to the FY 2024 
IPPS/LTCH PPS correction notice (88 FR 77211) for further discussion.
---------------------------------------------------------------------------

    \3\ As noted earlier in the discussion, the code titles were 
updated but the code numbers themselves did not change.
---------------------------------------------------------------------------

    In advance of this FY 2025 IPPS/LTCH PPS proposed rule, the 
manufacturer provided us with a list of the providers with which it 
indicated it has an explicit relationship to assist in our ongoing 
review of its request for reassignment of cases reporting spinal fusion 
procedures using an aprevoTM interbody fusion device from 
the lower severity spinal fusion MS-DRGs to the higher severity level 
spinal fusion MS-DRGs.
    To continue our analysis of cases reporting spinal fusion 
procedures using an aprevoTM customized interbody fusion 
device, we first analyzed claims data from the September 2023 update of 
the FY 2023 MedPAR file for MS-DRGs 453, 454, 455, 456, 457, 458, 459, 
and 460, and cases reporting any one of the previously listed procedure 
codes describing the performance of a spinal fusion procedure using an 
aprevoTM custom-made anatomically designed interbody fusion 
device.\3\ Our findings are shown in the following tables.

    We identified the majority of cases reporting the performance of a 
spinal fusion procedure using an aprevoTM custom-made 
anatomically designed interbody fusion device in MS-DRGs 453, 454, and 
455 with a total of 242 cases (26 + 129 + 87 = 242) with an average 
length of stay of 4.6 days and average costs of $68,526. The 26 cases 
found in MS-DRG 453 appear to have a comparable average length of stay 
(9.8 days versus 9.5 days) and higher average costs ($99,162 versus 
$80,420) compared to all the cases in MS-DRG 453, with a difference in 
average costs of $18,742 for the cases reporting the performance of a 
spinal fusion procedure using an aprevoTM custom-made 
anatomically designed interbody fusion device. The 129 cases found in 
MS-DRG 454 appear to have a comparable average length of stay (4.9 days 
versus 4.3 days) and higher average costs ($71,527 versus $54,983) 
compared to all the cases in MS-DRG 454, with a difference in average 
costs of $16,544 for the cases reporting the performance of a spinal 
fusion procedure using an aprevoTM custom-made anatomically 
designed interbody fusion device. The 87 cases found in MS-DRG 455 have 
an identical average length of stay of 2.6 days in comparison to all 
the cases in MS-DRG 455, however, the difference in average costs is 
$13,907 ($54,922-$41,015 = $13,907) for the cases reporting the 
performance of a spinal fusion procedure using an

[[Page 35974]]

aprevoTM custom-made anatomically designed interbody fusion 
device.
    For MS-DRGs 456, 457, and 458, we found a total of 19 cases (2 + 11 
+ 6 = 19) reporting the performance of a spinal fusion procedure using 
an aprevoTM custom-made anatomically designed interbody 
fusion device with an average length of stay of 4.7 days and average 
costs of $51,384. The 2 cases found in MS-DRG 456 have a shorter 
average length of stay (8.5 days versus 12.6 days) and lower average 
costs ($69,009 versus $76,060) compared to all the cases in MS-DRG 456. 
The 11 cases found in MS-DRG 457 also have a shorter average length of 
stay (5.0 days versus 6.1 days) and lower average costs ($47,221 versus 
$52,179). For MS-DRG 458, we found 6 cases reporting the performance of 
a spinal fusion procedure using an aprevoTM custom-made 
anatomically designed interbody fusion device with a comparable average 
length of stay (3.0 days versus 3.1 days) and higher average costs 
($53,140 versus $39,260) compared to the average costs of all the cases 
in MS-DRG 458, with a difference in average costs of $13,880 ($53,140-
$39,260 = $13,880) for the cases reporting the performance of a spinal 
fusion procedure using an aprevoTM custom-made anatomically 
designed interbody fusion device.
    For MS-DRGs 459 and 460, we found a total of 65 cases reporting the 
performance of a spinal fusion procedure using an aprevoTM 
custom-made anatomically designed interbody fusion device with an 
average length of stay of 2.7 days and average costs of $57,128. The 
single case found in MS-DRG 459 had a longer average length of stay (22 
days versus 9.6 days) and higher average costs ($288,499 versus 
$53,192) compared to the average costs of all the cases in MS-DRG 459. 
For MS-DRG 460, the 64 cases reporting the performance of a spinal 
fusion procedure using an aprevoTM custom-made anatomically 
designed interbody fusion device had a shorter average length of stay 
(2.4 days versus 3.4 days) and higher average cost ($53,513 versus 
$32,586), compared to all the cases in MS-DRG 460, with a difference in 
average costs of $20,927 ($53,513-$32,586 = $20,927) for the cases 
reporting the performance of a spinal fusion procedure using an 
aprevoTM custom-made anatomically designed interbody fusion 
device.
    As discussed in the FY 2024 final rule, the manufacturer expressed 
concern that there may be unintentional miscoded claims from providers 
with whom they do not have an explicit relationship and, as previously 
discussed, subsequently provided the list of providers with which it 
indicated it has an explicit relationship to assist in our ongoing 
review. In connection with the list of providers submitted, the 
manufacturer also resubmitted claims data from the Standard Analytical 
File (SAF) that included FY 2022 claims and the first two quarters 
(discharges beginning October 1, 2022 through March 31, 2023) of FY 
2023 from these providers. We note that the list of providers the 
manufacturer submitted to us was considered applicable for the dates of 
service in connection with the resubmitted claims data. The 
manufacturer stated that the list of providers with which it has an 
explicit relationship is subject to change on a weekly basis as 
additional providers begin to use the technology. The manufacturer also 
clarified that the external customer data it had previously referenced 
in connection with the FY 2024 rulemaking that was received directly 
from the providers with which it has an explicit relationship is 
Medicare data. We reviewed the September update of the FY 2022 MedPAR 
file and compared it against the claims data file with the list of 
providers submitted by the manufacturer for FY 2022. In this updated 
analysis of the September update of the FY 2022 MedPAR claims data, we 
were able to confirm that the majority of the cases for the providers 
with which the manufacturer indicated it has an explicit relationship 
matched the claims data in our FY 2022 MedPAR file. However, we 
identified 3 claims that appeared in the manufacturer's file that were 
not found in our FY 2022 MedPAR file and could not be validated. Next, 
we reviewed the September update of the FY 2023 MedPAR file and 
compared it against the claims data file with the list of providers 
submitted by the manufacturer for the first two quarters of FY 2023. We 
were able to confirm that the majority of the cases for the providers 
with which the manufacturer indicated it has an explicit relationship 
matched the claims data in our FY 2023 MedPAR file. However, we 
identified 2 claims that appeared in the manufacturer's file that were 
not found in our FY 2023 MedPAR file and also could not be validated.
    In our analysis of the cases reporting the performance of a spinal 
fusion procedure using an aprevoTM custom-made anatomically 
designed interbody fusion device in MS-DRGs 453, 454, 455, 456, 457, 
458, 459, and 460 from the September update of the FY 2023 MedPAR file, 
we also reviewed the findings for cases identified based on the list of 
providers with which the manufacturer indicated it has an explicit 
relationship and cases based on other providers, (that is, those 
providers not included on the manufacturer's list), and compared those 
to the findings from all the cases we identified in the September 
update of the FY 2023 MedPAR file reporting the performance of a spinal 
fusion procedure using an aprevoTM custom-made anatomically 
designed interbody fusion device in MS-DRGs 453, 454, 455, 456, 457, 
458, 459, and 460. The findings from our analysis are shown in the 
following table. We note that there were no cases found to report the 
performance of a spinal fusion procedure using an aprevoTM 
custom-made anatomically designed interbody fusion device based on the 
list of providers submitted by the manufacturer in MS-DRG 456.

[[Page 35975]]

    For MS-DRG 453, the data show that of the 26 cases found to report 
the performance of a spinal fusion procedure using an 
aprevoTM custom-made anatomically designed interbody fusion 
device from the FY 2023 MedPAR file, 10 cases were reported based on 
the manufacturer's provider list, and 16 cases were reported based on 
other providers. The average length of stay is longer (10.5 days versus 
9.4 days), and the average costs are higher ($118,863 versus $86,849) 
for the 10 cases reported based on the manufacturer's provider list 
compared to the 16 cases that were reported based on other providers. 
For MS-DRG 454, the data show that of the 129 cases found to report the 
performance of a spinal fusion procedure using an aprevoTM 
custom-made anatomically designed interbody fusion device from the FY 
2023 MedPAR file, 48 cases were reported based on the manufacturer's 
provider list, and 81 cases were reported based on other providers. The 
average length of stay is longer (6.3 days versus 4.1 days), and the 
average costs are higher ($81,680 versus $65,510) for the 48 cases 
reported based on the manufacturer's provider list compared to the 81 
cases that were reported based on other providers. For MS-DRG 455, the 
data show that of the 87 cases found to report the performance of a 
spinal fusion procedure using an aprevoTM custom-made 
anatomically designed interbody fusion device from the FY 2023 MedPAR 
file, 14 cases were reported based on the manufacturer's provider list, 
and 73 cases were reported based on other providers. The average

[[Page 35976]]

length of stay is shorter (2.5 days versus 2.6 days), and the average 
costs are higher ($61,637 versus $53,634) for the 14 cases reported 
based on the manufacturer's provider list compared to the 73 cases that 
were reported based on other providers.
    For MS-DRG 456, the data show that of the 2 cases found to report 
the performance of a spinal fusion procedure using an 
aprevoTM custom-made anatomically designed interbody fusion 
device from the FY 2023 MedPAR file, there were no cases reported based 
on the manufacturer's provider list and the 2 cases reported were based 
on other providers. For MS-DRG 457, the data show that of the 11 cases 
found to report the performance of a spinal fusion procedure using an 
aprevoTM custom-made anatomically designed interbody fusion 
device from the FY 2023 MedPAR file, 2 cases were reported based on the 
manufacturer's provider list, and 9 cases were reported based on other 
providers. The average length of stay is shorter (4.5 days versus 5.1 
days), and the average costs are higher ($53,113 versus $45,912) for 
the 2 cases reported based on the manufacturer's provider list compared 
to the 9 cases that were reported based on other providers. For MS-DRG 
458, the data show that of the 6 cases found to report the performance 
of a spinal fusion procedure using an aprevoTM custom-made 
anatomically designed interbody fusion device from the FY 2023 MedPAR 
file, 3 cases were reported based on the manufacturer's provider list, 
and 3 cases were reported based on other providers. The average length 
of stay is longer (3.3 days versus 2.7 days), and the average costs are 
lower ($52,760 versus $53,520) for the 3 cases reported based on the 
manufacturer's provider list compared to the 3 cases that were reported 
for other providers.
    For MS-DRG 459, the data show that the single case found to report 
the performance of a spinal fusion procedure using an 
aprevoTM custom-made anatomically designed interbody fusion 
device from the FY 2023 MedPAR file was based on the manufacturer's 
provider list. There were no cases reported based on other providers. 
For MS-DRG 460, the data show that of the 64 cases found to report the 
performance of a spinal fusion procedure using an aprevoTM 
custom-made anatomically designed interbody fusion device from the FY 
2023 MedPAR file, 13 cases were reported based on the manufacturer's 
provider list, and 51 cases were reported based on other providers. The 
average length of stay is comparable (2.6 days versus 2.3 days), and 
the average costs are higher ($62,829 versus $51,138) for the 13 cases 
reported based on the manufacturer's provider list compared to the 51 
cases that were reported from other providers.
    We considered these data findings with regard to the concerns 
expressed by the manufacturer that there may be unintentional miscoded 
claims reporting the performance of a spinal fusion procedure using an 
aprevoTM custom-made anatomically designed interbody fusion 
device from providers with whom the manufacturer does not have an 
explicit relationship. Based on our review and analysis of the claims 
data, we are unable to confirm that the claims from these providers 
with whom the manufacturer indicated that it does not have an explicit 
relationship are miscoded.
    We note that, while a newly established ICD-10 code may be 
associated with an application for new technology add-on payment, such 
codes are not generally established to be product specific. If, after 
consulting the official coding guidelines, a provider determines that 
an ICD-10 code associated with a new technology add-on payment 
describes the technology that they are billing, the hospital may report 
the code and be eligible to receive the associated add-on payment. 
Providers are responsible for ensuring that they are billing correctly 
for the services they render. In addition, as we noted in the FY 2018 
IPPS/LTCH PPS final rule (82 FR 38012), coding advice is issued 
independently from payment policy. We also note that, historically, we 
have not provided coding advice in rulemaking with respect to policy 
(82 FR 38045). As one of the Cooperating Parties for ICD-10, we 
collaborate with the American Hospital Association (AHA) through the 
Coding Clinic for ICD-10-CM and ICD-10-PCS to promote proper coding. We 
recommend that an entity seeking coding guidance submit any questions 
pertaining to correct coding to the AHA.
    Accordingly, after review of the list of providers and associated 
claims data submitted by the manufacturer, and our analysis of the 
MedPAR data, we believe these MedPAR data are appropriate for our FY 
2025 analysis. Therefore, in assessing the request for reassignment of 
cases reporting the performance of a spinal fusion procedure using an 
aprevoTM custom-made anatomically designed interbody fusion 
device from the lower severity MS-DRG 455 to the higher severity MS-DRG 
453, from the lower severity MS-DRG 458 to the higher severity level 
MS-DRG 456 when a diagnosis of malalignment is reported, and cases from 
MS-DRGs 459 and 460 to MS-DRG 456 for FY 2025, we considered all the 
claims data reporting the performance of a spinal fusion procedure, 
including those spinal fusion procedures using an aprevoTM 
custom-made anatomically designed interbody fusion device as identified 
in the September update of the FY 2023 MedPAR file for these MS-DRGs. 
Consequently, our analysis also included claims based on the list of 
providers submitted by the manufacturer as well as other providers.
    Based on the findings from our analysis and clinical review, we do 
not believe the requested reassignments are supported. Specifically, it 
would not be appropriate to propose to reassign the 87 cases reporting 
the performance of a spinal fusion procedure using an 
aprevoTM custom-made anatomically designed interbody fusion 
device from the lower severity level MS-DRG 455 (without CC/MCC) with 
an average length of stay of 2.6 days and average costs of $54,922 to 
the higher severity level MS-DRG 453 (with MCC) with an average length 
of stay of 9.5 days and average costs of $80,420. If we were to propose 
to reassign the 87 cases from the lower severity MS-DRG 455 to the 
higher severity MS-DRG 453, the MS-DRGs would no longer be clinically 
coherent with regard to severity of illness of the patients, and the 
cases would reflect a difference in resource utilization, as 
demonstrated by the difference in average costs of approximately 
$25,498 ($80,420-$54,922 = $25,498), as well as a difference in average 
length of stay (2.6 days versus 9.5 days) compared to all the cases in 
MS-DRG 453. Similarly, it would not be appropriate to propose to 
reassign the 6 cases reporting the performance of a spinal fusion 
procedure using an aprevoTM custom-made anatomically 
designed interbody fusion device from the lower severity level MS-DRG 
458 (without CC/MCC) with an average length of stay of 3.0 days and 
average costs of $53,140 to the higher severity level MS-DRG 456 (with 
MCC) with an average length of stay of 12.6 days and average costs of 
$76,060. If we were to propose to reassign the 6 cases from the lower 
severity MS-DRG 458 to the higher severity MS-DRG 456, the MS-DRGs 
would no longer be clinically coherent with regard to severity of 
illness of the patients and the cases would reflect a difference in 
resource utilization, as demonstrated by the difference in average 
costs of approximately $22,920 ($76,060-$53,140 = $22,920) as well as a 
difference in average length of stay

[[Page 35977]]

(3.0 days versus 12.6 days) compared to all the cases in MS-DRG 456. 
Finally, it would not be appropriate nor consistent with the definition 
of the MS-DRGs to propose to reassign the 65 cases reporting the 
performance of a spinal fusion procedure using an aprevoTM 
custom-made anatomically designed interbody fusion device from MS-DRGs 
459 and 460 with an average length of stay of 2.7 days and average 
costs of $57,128 to MS-DRG 456. In addition to the cases reflecting a 
difference in resource utilization as demonstrated by the difference in 
average costs of approximately $18,932 ($76,060-$57,128 = $18,932) as 
well as having a shorter average length of stay (2.7 days versus 12.6 
days), we note that the logic for case assignment to MS-DRGs 456, 457, 
and 458 is specifically defined by principal diagnosis logic. As such, 
cases grouping to this set of MS-DRGs require a principal diagnosis of 
spinal curvature, malignancy, or infection, or an extensive fusion 
procedure. Therefore, it would not be clinically appropriate to propose 
to reassign cases from MS-DRGs 459 and 460 that do not have a principal 
diagnosis of spinal curvature, malignancy, or infection, or an 
extensive fusion procedure, and are not consistent with the logic for 
case assignment to MS-DRG 456.
    In light of the higher average costs of the cases reporting the 
performance of a spinal fusion procedure using an aprevoTM 
custom-made anatomically designed interbody fusion device in MS-DRGs 
453, 454, 455, 458, and 460, we further reviewed the claims data for 
cases reporting the performance of a spinal fusion procedure using an 
aprevoTM custom-made anatomically designed interbody fusion 
device in these MS-DRGs and identified a wide range in the average 
length of stay and average costs. For example, in MS-DRG 453, the 
average length of stay for the 26 cases reporting the performance of a 
spinal fusion procedure using an aprevoTM custom-made 
anatomically designed interbody fusion device ranged from 3.0 days to 
27 days and the average costs ranged from $28,054 to $177,919. In MS-
DRG 454, the average length of stay for the 129 cases reporting the 
performance of a spinal fusion procedure using an aprevoTM 
custom-made anatomically designed interbody fusion device ranged from 
1.0 day to 16 days and the average costs ranged from $10,242 to 
$316,780. In MS-DRG 455, the average length of stay for the 87 cases 
reporting the performance of a spinal fusion procedure using an 
aprevoTM custom-made anatomically designed interbody fusion 
device ranged from 1.0 day to 9.0 days and the average costs ranged 
from $7,961 to $216,200. In MS-DRG 456, the average length of stay for 
the 2 cases reporting the performance of a spinal fusion procedure 
using an aprevoTM custom-made anatomically designed 
interbody fusion device were 8.0 days and 9.0 days, respectively, with 
average costs of $107,457 and $30,560, respectively. In MS-DRG 457, the 
average length of stay for the 11 cases reporting the performance of a 
spinal fusion procedure using an aprevoTM custom-made 
anatomically designed interbody fusion device ranged from 1.0 day to 17 
days and the average costs ranged from $25,955 to $89,176. In MS-DRG 
458, the average length of stay for the 6 cases reporting the 
performance of a spinal fusion procedure using an aprevoTM 
custom-made anatomically designed interbody fusion device ranged from 
1.0 day to 5.0 days and the average costs ranged from $33,165 to 
$78,720. In MS-DRG 459, the length of stay for the single case 
reporting the performance of a spinal fusion procedure using an 
aprevoTM custom-made anatomically designed interbody fusion 
device was 22 days with a cost of $288,499, indicating it is an 
outlier. In MS-DRG 460, the average length of stay for the 64 cases 
reporting the performance of a spinal fusion procedure using an 
aprevoTM custom-made anatomically designed interbody fusion 
device ranged from 1.0 day to 8.0 days and the average costs ranged 
from $8,981 to $325,104.
    In our analysis of the claims data for MS-DRGs 453, 454, and 455, 
we also identified a number of cases for which additional spinal fusion 
procedures were performed, beyond the logic for case assignment to the 
respective MS-DRG. For example, the logic for case assignment to MS-
DRGs 453, 454, and 455 requires at least one anterior column fusion and 
one posterior column fusion (that is, combined anterior and posterior 
fusion). We note that the aprevoTM custom-made anatomically 
designed interbody fusion device is used in the performance of an 
anterior column fusion. Findings from our analysis of MS-DRG 453 show 
that of the 26 cases reporting a combined anterior and posterior fusion 
(including an aprevoTM custom-made anatomically designed 
interbody fusion device), 24 cases also reported another spinal fusion 
procedure. We categorized these cases as ``multiple level fusions'' 
where another procedure code describing a spinal fusion procedure was 
reported in addition to the combined anterior and posterior fusion 
procedure codes. Findings from our analysis of MS-DRG 454 show that of 
the 129 cases reporting a combined anterior and posterior fusion 
(including an aprevoTM custom-made anatomically designed 
interbody fusion device), 100 cases also reported another spinal fusion 
procedure. Lastly, findings from our analysis of MS-DRG 455 show that 
of the 87 cases reporting a combined anterior and posterior fusion 
(including an aprevoTM custom-made anatomically designed 
interbody fusion device), 51 cases also reported another spinal fusion 
procedure.
    While the findings from our analysis indicate a wide range in the 
average length of stay and average costs for cases reporting the 
performance of a spinal fusion procedure using an aprevoTM 
custom-made anatomically designed interbody fusion device, we believe 
the increase in resource utilization for certain cases may be partially 
attributable to the performance of multiple level fusion procedures 
and, specifically for MS-DRGs 453 and 454, the reporting of secondary 
diagnosis MCC and CC conditions. Our analysis of the data for MS-DRGs 
453 and 454 show that the cases reporting the performance of a spinal 
fusion procedure using an aprevoTM custom-made anatomically 
designed interbody fusion device also reported multiple MCC and CC 
conditions, which we believe may be an additional contributing factor 
to the increase in resource utilization for these cases, combined with 
the reported performance of multiple level fusions.
    In our analysis of the data for MS-DRGs 453, 454, and 455 and cases 
reporting the performance of a spinal fusion procedure using an 
aprevoTM custom-made anatomically designed interbody fusion 
device, we also identified other procedures that were reported, some of 
which are designated as operating room (O.R.) procedures, that we 
believe may be another contributing factor to the increase in resource 
utilization and complexity for these cases. (We note that because a 
discectomy is frequently performed in connection with a spinal fusion 
procedure, we did not consider these procedures as contributing factors 
to consumption of resources in these spinal fusion cases). In the 
tables that follow we provide a list of the top 5 MCC and CC 
conditions, as well as the top 5 O.R. procedures (excluding discectomy) 
reported in MS-DRGs 453, 454, and 455 that we believe may be 
contributing factors to the increase in resource utilization and 
complexity for these cases. We note that the logic for case assignment 
to MS-DRG 453 includes the reporting of at least one

[[Page 35978]]

secondary diagnosis MCC condition (``with MCC'') and cases that group 
to this MS-DRG may also report secondary diagnosis CC conditions. We 
are providing the frequency data for both the top 5 secondary diagnosis 
MCC conditions and the top 5 secondary diagnosis CC conditions, in 
addition to the top 5 O.R. procedures (excluding discectomy) that were 
reported for spinal fusion cases with an aprevoTM custom-
made anatomically designed interbody fusion device in MS-DRG 453. 
Because the logic for case assignment to MS-DRG 454 includes the 
reporting of at least one secondary diagnosis CC condition (``with 
CC'') we are providing the top 5 secondary diagnosis CC conditions and 
the top 5 O.R. procedures (excluding discectomy) that were reported for 
spinal fusion cases with an aprevoTM custom-made 
anatomically designed interbody fusion device in MS-DRG 454. We note 
that the logic for case assignment to MS-DRG 455 is ``without CC/MCC'' 
and does not include any secondary diagnosis MCC or CC conditions, 
therefore, we are only providing a table with the top 5 O.R. procedures 
(excluding discectomy) reported for that MS-DRG in addition to a spinal 
fusion procedure.

    As previously summarized, our analysis of the claims data for cases 
reporting the performance of a spinal fusion procedure using an 
aprevoTM custom-made anatomically designed interbody fusion 
device demonstrated a low volume of cases and higher average costs in 
comparison to all the cases in their respective MS-DRGs (that is, in 
MS-DRGs 453, 454, 455, 458, 459, and 460). Therefore, we expanded our 
analysis to include all spinal fusion cases in MS-DRGs 453, 454, 455, 
456, 457, 458, 459, and 460 to identify and further examine the cases 
reporting multiple level fusions versus single level fusions, multiple 
MCCs or CCs, and other O.R. procedures as we believed that clinically, 
all of these factors may contribute to increases in resource 
utilization, severity of illness and technical complexity.
    We began our expanded analysis with MS-DRGs 453, 454, and 455. 
Based on the findings for a subset of the cases (that is, the subset of 
cases reporting the performance of a spinal fusion procedure using an 
aprevoTM custom-made anatomically designed interbody fusion 
device) in these MS-DRGs as previously discussed, and our review of the 
logic for case assignment to these MS-DRGs, we developed three 
categories of spinal fusion procedures to further examine. The first 
category was for the single level combined anterior and posterior 
fusions except cervical, the second category was for the multiple level 
combined anterior and posterior fusions except cervical and the third 
category was for the combined anterior and posterior cervical spinal 
fusions. We refer the reader to Table 6P.2d for the list of procedure 
codes we identified to categorize the single level combined anterior 
and posterior fusions except cervical, Table 6P.2e for the list of 
procedure codes we identified to categorize the multiple level combined 
anterior and posterior fusions except cervical, and Table 6P.2f for the 
list of procedure codes we identified to categorize the combined 
anterior and posterior cervical spinal fusions. Findings from our 
analysis are shown in the following table.
[GRAPHIC] [TIFF OMITTED] TP02MY24.030

BILLING CODE 4120-01-C
    The data show that across MS-DRGs 453, 454, and 455, cases 
reporting multiple level combined anterior and posterior fusion 
procedures have a comparable average length of stay (9.6 days versus 
9.5 days, 4.8 days versus 4.3 days, and 3.0 days versus 2.6 days, 
respectively) and higher average costs ($91,358 versus $80,420, $64,065 
versus $54,983, and $50,097 versus $41,015) compared to all the cases 
in MS-DRGs 453, 454, and 455, respectively. The data also show that 
across MS-DRGs 453, 454, and 455, cases reporting multiple level 
combined anterior and posterior fusion procedures have a longer average 
length of stay (9.6 days versus 6.4 days, 4.8 days versus 3.4 days, and 
3.0 days versus 2.3 days, respectively) and higher average costs 
($91,358 versus $47,031, $64,065 versus $38,107, and $50,097 versus 
$33,010, respectively) compared to cases reporting a single level 
combined anterior and posterior fusion. For cases reporting a combined 
anterior and posterior cervical fusion across MS-DRGs 453 and 454, the 
data show a longer average length of stay (12.5 days versus 9.5 days, 
and 5.1 days versus 4.3 days, respectively) compared to all the cases 
in MS-DRGs 453 and 454 and a comparable average length of stay (2.9 
days versus 2.6 days) for cases reporting a combined anterior and 
posterior cervical fusion in MS-DRG 455. The data also show that across 
MS-DRGs 453, 454, and 455, cases reporting a combined anterior and 
posterior cervical fusion have higher average costs ($75,077 versus 
$47,031, $52,274 versus $38,107, and $37,515 versus $33,010, 
respectively) compared to the single level combined anterior and 
posterior fusion cases.
    The data also reflect that in applying the logic that was developed 
for the three categories of spinal fusion in MS-DRGs 453, 454, and 455 
(single level combined anterior and posterior fusion except cervical, 
multiple level combined anterior and posterior fusion except cervical, 
and combined anterior and posterior cervical fusion), there is a

[[Page 35980]]

small redistribution of cases from the current MS-DRGs 453, 454, and 
455 to other spinal fusion MS-DRGs because the logic for case 
assignment to MS-DRGs 453, 454, and 455 is currently satisfied with any 
one procedure code from the anterior spinal fusion logic list and any 
one procedure code from the posterior spinal fusion logic list, 
however, the logic lists that were developed for our analysis using the 
three categories of spinal fusion are comprised of specific procedure 
code combinations to satisfy the criteria for case assignment to any 
one of the three categories developed. For example, based on our 
analysis of MS-DRG 453 using the September update of the FY 2023 MedPAR 
file, the total number of cases found in MS-DRG 453 is 4,066 and with 
application of the logic for each of the three categories, the total 
number of cases in MS-DRG 453 is 4,042 (791 + 2,664 + 587 = 4,042), a 
difference of 24 cases. Using the September update of the FY 2023 
MedPAR file, the total number of cases found in MS-DRG 454 is 20,425 
and with application of the logic for each of the three categories, the 
total number of cases in MS-DRG 454 is 20,370 (6,481 + 12,498 + 1,391 = 
20,370), a difference of 55 cases. Lastly, using the September update 
of the FY 2023 MedPAR file, the total number of cases found in MS-DRG 
455 is 17,000 and with application of the logic for each of the three 
categories, the total number of cases in MS-DRG 455 is 16,987 (9,763 + 
6,879 + 345 = 16,987), a difference of 13 cases. Overall, a total of 92 
cases are redistributed from MS-DRGs 453, 454, and 455 to other spinal 
fusion MS-DRGs.
    The findings from our analysis of MS-DRGs 453, 454, and 455 are 
consistent with the expectation that clinically, the greater the number 
of spinal fusion procedures performed during a single procedure (for 
example, intervertebral levels fused), the greater the consumption of 
resources expended. We believe the use of interbody fusion cages, other 
types of spinal instrumentation, operating room time, comorbidities, 
pharmaceuticals, and length of stay may all be contributing factors to 
resource utilization for spinal fusion procedures. In addition, it is 
expected that as a result of potential changes to the logic for case 
assignment to a MS-DRG, there will be a redistribution of cases among 
the MS-DRGs.
    Based on our review and analysis of the spinal fusion cases in MS-
DRGs 453, 454, and 455, we believe new MS-DRGs are warranted to 
differentiate between multiple level combined anterior and posterior 
spinal fusions except cervical, single level combined anterior and 
posterior spinal fusions except cervical, and combined anterior and 
posterior cervical spinal fusions, to more appropriately reflect 
utilization of resources for these procedures, including those 
performed with an aprevoTM custom-made anatomically designed 
interbody fusion device. We note that the performance of a spinal 
fusion procedure using an aprevoTM custom-made anatomically 
designed interbody fusion device as identified by any one of the 12 
previously listed procedure codes would not be reported for a cervical 
spinal fusion procedure as reflected in Table 6P.2f associated with 
this proposed rule and available on the CMS website at: https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps.
    To compare and analyze the impact of our suggested modifications, 
we ran simulations using claims data from the September 2023 update of 
the FY 2023 MedPAR file. The following table illustrates our findings 
for all 23,017 cases reporting procedure codes describing multiple 
level combined anterior and posterior spinal fusions.
[GRAPHIC] [TIFF OMITTED] TP02MY24.031

    Consistent with our established process as discussed in section 
II.C.1.b. of the preamble of this proposed rule, once the decision has 
been made to propose to make further modifications to the MS-DRGs, such 
as creating a new base MS-DRG, all five criteria to create subgroups 
must be met for the base MS-DRG to be split (or subdivided) by a CC 
subgroup. Therefore, we applied the criteria to create subgroups in a 
base MS-DRG. We note that, as shown in the table that follows, a three-
way split of this proposed new base MS-DRG was met. The following table 
illustrates our findings.
[GRAPHIC] [TIFF OMITTED] TP02MY24.032

    For the proposed new MS-DRGs, there is (1) at least 500 or more 
cases in the MCC group, the CC subgroup, and in the without CC/MCC 
subgroup; (2) at least 5 percent of the cases are in the MCC subgroup, 
the CC subgroup, and in the without CC/MCC subgroup; (3) at least a 20 
percent difference in average costs between the MCC subgroup and the CC 
subgroup and between the CC group and NonCC subgroup; (4) at least a 
$2,000 difference in average costs between the MCC subgroup and the 
with CC subgroup and between the CC subgroup and NonCC subgroup; and 
(5) at least a 3-percent reduction in cost variance, indicating that 
the proposed severity level splits increase the explanatory power of 
the base MS-DRG in capturing differences in expected cost between the 
proposed MS-DRG severity level splits by at least 3 percent and thus 
improve the overall accuracy of the IPPS payment system.
    As a result, for FY 2025, we are proposing to create new MS-DRG 426 
(Multiple Level Combined Anterior and Posterior Spinal Fusion Except 
Cervical with MCC), new MS-DRG 427 (Multiple Level Combined Anterior 
and Posterior Spinal Fusion Except Cervical with CC), and new MS-DRG 
428 (Multiple Level Combined Anterior and Posterior Spinal Fusion 
Except Cervical without CC/MCC). The following table reflects a 
simulation of the proposed new MS-DRGs.

[[Page 35981]]

[GRAPHIC] [TIFF OMITTED] TP02MY24.033

    The next step in our analysis of the impact of our suggested 
modifications to MS-DRGs 453, 454, and 455 was to review the cases 
reporting single combined anterior and posterior cervical fusions. The 
following table illustrates our findings for all 16,059 cases reporting 
procedure codes describing single level combined anterior and posterior 
spinal fusions.
[GRAPHIC] [TIFF OMITTED] TP02MY24.034

    Consistent with our established process as discussed in section 
II.C.1.b. of the preamble of this proposed rule, once the decision has 
been made to propose to make further modifications to the MS-DRGs, such 
as creating a new base MS-DRG, all five criteria to create subgroups 
must be met for the base MS-DRG to be split (or subdivided) by a CC 
subgroup. Therefore, we applied the criteria to create subgroups in a 
base MS-DRG. We note that, as shown in the table that follows, a three-
way split of this proposed new base MS-DRG failed to meet the criterion 
that at least 5% or more of the cases are in the MCC subgroup. It also 
failed to meet the criterion that there be at least a 20% difference in 
average costs between the CC and NonCC (without CC/MCC) subgroup. The 
following table illustrates our findings.
[GRAPHIC] [TIFF OMITTED] TP02MY24.035

    As discussed in section II.C.1.b. of the preamble of this proposed 
rule, if the criteria for a three-way split fail, the next step is to 
determine if the criteria are satisfied for a two-way split. We 
therefore applied the criteria for a two-way split for the ``with MCC 
and without MCC'' subgroups. We note that, as shown in the table that 
follows, a two-way split of this base MS-DRG failed to meet the 
criterion that there be at least 5% or more of the cases in the with 
MCC subgroup.
[GRAPHIC] [TIFF OMITTED] TP02MY24.036

    We then applied the criteria for a two-way split for the ``with CC/
MCC and without CC/MCC'' subgroups. As shown in the table that follows, 
a two-way split of this base MS-DRG failed to meet the criterion that 
there be at least a 20% difference in average costs between the ``with 
CC/MCC and without CC/MCC'' subgroup.
[GRAPHIC] [TIFF OMITTED] TP02MY24.037

    We note that because the criteria for both of the two-way splits 
failed, a split (or CC subgroup) is not warranted for the proposed new 
base MS-DRG. As a result, for FY 2025, we are proposing to create new 
base MS-DRG 402 (Single Level Combined Anterior and Posterior Spinal 
Fusion Except Cervical). The following table reflects a simulation of 
the proposed new base MS-DRG.
[GRAPHIC] [TIFF OMITTED] TP02MY24.038

    For the final step in our analysis of the impact of our suggested 
modifications to MS-DRGs 453, 454, and 455 we reviewed the cases 
reporting combined anterior and posterior cervical fusions. The 
following table illustrates our findings for all 2,323 cases reporting 
procedure codes

[[Page 35982]]

describing combined anterior and posterior cervical spinal fusions.
[GRAPHIC] [TIFF OMITTED] TP02MY24.039

    Consistent with our established process as discussed in section 
II.C.1.b. of the preamble of this proposed rule, once the decision has 
been made to propose to make further modifications to the MS-DRGs, such 
as creating a new base MS-DRG, all five criteria to create subgroups 
must be met for the base MS-DRG to be split (or subdivided) by a CC 
subgroup. Therefore, we applied the criteria to create subgroups in a 
base MS-DRG. We note that, as shown in the table that follows, a three-
way split of this proposed new base MS-DRG failed to meet the criterion 
that that there be at least 500 cases in the NonCC subgroup.
[GRAPHIC] [TIFF OMITTED] TP02MY24.040

    As discussed in section II.C.1.b. of the preamble of this proposed 
rule, if the criteria for a three-way split fail, the next step is to 
determine if the criteria are satisfied for a two-way split. We 
therefore applied the criteria for a two-way split for the ``with MCC 
and without MCC'' subgroups. We note that, as shown in the table that 
follows, a two-way split of this proposed new base MS-DRG was met. For 
the proposed MS-DRGs, there is at least (1) 500 or more cases in the 
MCC group and in the without MCC subgroup; (2) 5 percent or more of the 
cases in the MCC group and in the without MCC subgroup; (3) a 20 
percent difference in average costs between the MCC group and the 
without MCC group; (4) a $2,000 difference in average costs between the 
MCC group and the without MCC group; and (5) a 3-percent reduction in 
cost variance, indicating that the proposed severity level splits 
increase the explanatory power of the base MS-DRG in capturing 
differences in expected cost between the proposed MS-DRG severity level 
splits by at least 3 percent and thus improve the overall accuracy of 
the IPPS payment system. The following table illustrates our findings 
for the suggested MS-DRGs with a two-way severity level split.
[GRAPHIC] [TIFF OMITTED] TP02MY24.041

    Accordingly, because the criteria for the two-way split were met, 
we believe a split (or CC subgroup) is warranted for the proposed new 
base MS-DRG. As a result, for FY 2025, we are proposing to create new 
MS-DRG 429 (Combined Anterior and Posterior Cervical Spinal Fusion with 
MCC) and new MS-DRG 430 (Combined Anterior and Posterior Cervical 
Spinal Fusion without MCC). The following table reflects a simulation 
of the proposed new MS-DRGs.
[GRAPHIC] [TIFF OMITTED] TP02MY24.042

    We then analyzed the cases reporting spinal fusion procedures in 
MS-DRGs 456, 457, and 458. As previously described, the logic for case 
assignment to MS-DRGs 456, 457, and 458 is defined by principal 
diagnosis logic and extensive fusion procedures. Cases reporting a 
principal diagnosis of spinal curvature, malignancy, or infection or an 
extensive fusion procedure will group to these MS-DRGs. We refer the 
reader to the ICD-10 MS-DRG Definitions Manual Version 41.1 available 
on the CMS website at: https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps/ms-drg-classifications-and-software for complete documentation of the GROUPER logic for MS-
DRGs 456, 457, and 458.
    As also previously described, in our initial analysis of cases 
reporting the performance of a spinal fusion procedure using an 
aprevoTM custom-made anatomically designed interbody fusion 
device, the 13 cases we found in MS-DRGs 456 and 457 (2 + 11 = 13, 
respectively) appeared to be grouping appropriately, however, the 
average costs for the 6 cases found in MS-DRG 458 showed a difference 
of approximately $13,880. Because of the low volume of cases reporting 
the performance of a spinal fusion procedure using an 
aprevoTM custom-made anatomically designed interbody fusion 
device in the ``without CC/MCC'' MS-DRG 458, and the low volume of 
cases reporting the performance of a spinal fusion procedure using an 
aprevoTM custom-made anatomically designed interbody fusion 
device in MS-DRGs 456, 457, and 458 overall (2 + 11 + 6 = 19), for this 
expanded review of the claims data, we are sharing the results of our 
analysis in association with cases reporting extensive fusion 
procedures in MS-DRGs 456, 457, and 458. Our findings are shown in the 
following table.

[[Page 35983]]

[GRAPHIC] [TIFF OMITTED] TP02MY24.043

    The data show that the 332 cases reporting an extensive fusion 
procedure in MS-DRG 456 have a shorter average length of stay (11.5 
days versus 12.6 days) and higher average costs ($89,773 versus 
$76,060) compared to all the cases in MS-DRG 456. For MS-DRG 457, the 
data show that the 171 cases reporting an extensive fusion have a 
comparable average length of stay (6.6 days versus 6.1 days) and higher 
average costs ($75,588 versus $52,179) compared to all the cases in MS-
DRG 457. Lastly, for MS-DRG 458, the data show that the 146 cases 
reporting an extensive fusion procedure have a comparable average 
length of stay (3.8 days versus 3.1 days) and higher average costs 
($48,035 versus $39,260) compared to all the cases in MS-DRG 458.
    We believe that over time, the volume of cases reporting the 
performance of a spinal fusion procedure using an aprevoTM 
custom-made anatomically designed interbody fusion device in MS-DRGs 
456, 457, and 458 may increase and we could consider further in the 
context of the cases reporting an extensive fusion procedure. However, 
due to the logic for case assignment to these MS-DRGs also being 
defined by diagnosis code logic, additional analysis would be needed 
prior to considering any modification to the current structure of these 
MS-DRGs. As we continue to evaluate how we may refine these spinal 
fusion MS-DRGs, we are also seeking public comments and feedback on 
other factors that should be considered in the potential restructuring 
of MS-DRGs 456, 457, and 458. Thus, for FY 2025, we are proposing to 
maintain the current structure of MS-DRGs 456, 457, and 458, without 
modification. Feedback and other suggestions for future rulemaking may 
be submitted by October 20, 2024 and directed to MEARISTM at 
https://mearis.cms.gov/public/home.
    Next, we performed an expanded analysis for spinal fusion cases 
reported in MS-DRGs 459 and 460. We note that cases grouping to MS-DRG 
459 have at least one secondary diagnosis MCC condition reported 
(``with MCC'') and because MS-DRG 460 is ``without MCC'', cases 
grouping to this MS-DRG may include the reporting of at least one 
secondary diagnosis CC condition (in addition to cases that may not 
report a CC (for example, NonCC)). Based on the findings for a subset 
of the cases (that is, the subset of cases reporting the performance of 
a spinal fusion procedure using an aprevoTM custom-made 
anatomically designed interbody fusion device) in these MS-DRGs as 
previously discussed, and our review of the logic for case assignment 
to these MS-DRGs, we developed two categories of spinal fusion 
procedures to further examine. The first category was for the single 
level spinal fusions except cervical, and the second category was for 
the multiple level spinal fusions except cervical. We refer the reader 
to Table 6P.2g for the list of procedure codes we identified to 
categorize the single level spinal fusions except cervical and Table 
6P.2h for the list of procedure codes we identified to categorize the 
multiple level spinal fusions except cervical. Findings from our 
analysis are shown in the following table.
[GRAPHIC] [TIFF OMITTED] TP02MY24.044

    The data show that the 2,069 cases reporting a multiple level 
spinal fusion except cervical in MS-DRG 459 have a longer average 
length of stay (10.1 days versus 9.6 days) and higher average costs 
($57,209 versus $53,192) when compared to all the cases in MS-DRG 459. 
The data also show that the 2,069 cases reporting a multiple level 
spinal fusion except cervical in MS-DRG 459 have a longer average 
length of stay (10.1 days versus 8.9 days) and higher average costs 
($57,209 versus $46,031) when compared to the 1,098 cases reporting a 
single level spinal fusion except cervical in MS-DRG 459. For MS-DRG 
460, the data show that the 14,677 cases reporting a multiple level 
spinal fusion except cervical have a comparable average length of stay 
(3.9 days versus 3.4 days) and higher average costs ($36,932 versus 
$32,586) when compared to all the cases in MS-DRG 460. The data also 
show that the 14,677 cases reporting a multiple level spinal fusion 
except cervical have a comparable average length of stay (3.9 days 
versus 3.0 days) and higher average costs ($36,932 versus $28,110) when 
compared to the 14,058 cases reporting a single level spinal fusion 
except cervical in MS-DRG 460.
    Based on our review and analysis of the spinal fusion cases in MS-
DRGs 459 and 460, we believe new MS-DRGs are warranted to differentiate 
between multiple level spinal fusions except cervical and single level 
spinal fusions except cervical to more appropriately reflect 
utilization of resources for these procedures, including those 
performed with an aprevoTM custom-made anatomically designed 
interbody fusion device.

[[Page 35984]]

    To compare and analyze the impact of our suggested modifications, 
we ran simulations using claims data from the September 2023 update of 
the FY 2023 MedPAR file. The following table illustrates our findings 
for all 16,746 cases reporting procedure codes describing multiple 
level spinal fusions except cervical.
[GRAPHIC] [TIFF OMITTED] TP02MY24.045

    Consistent with our established process as discussed in section 
II.C.1.b. of the preamble of this proposed rule, once the decision has 
been made to propose to make further modifications to the MS-DRGs, such 
as creating a new base MS-DRG, all five criteria to create subgroups 
must be met for the proposed new base MS-DRG to be split (or 
subdivided) by a CC subgroup. Therefore, we applied the criteria to 
create subgroups in a base MS-DRG. We note that, as shown in the table 
that follows, a three-way split of this proposed new base MS-DRG failed 
to meet the criterion that there be at least a 20% difference in 
average costs between the CC and NonCC (without CC/MCC) subgroup. The 
following table illustrates our findings.
[GRAPHIC] [TIFF OMITTED] TP02MY24.046

    As discussed in section II.C.1.b. of the preamble of this proposed 
rule, if the criteria for a three-way split fail, the next step is to 
determine if the criteria are satisfied for a two-way split. We 
therefore applied the criteria for a two-way split for the ``with MCC 
and without MCC'' subgroups. We note that, as shown in the table that 
follows, a two-way split of this proposed new base MS-DRG was met. For 
the proposed MS-DRGs, there is at least (1) 500 or more cases in the 
MCC group and in the without MCC subgroup; (2) 5 percent or more of the 
cases in the MCC group and in the without MCC subgroup; (3) a 20 
percent difference in average costs between the MCC group and the 
without MCC group; (4) a $2,000 difference in average costs between the 
MCC group and the without MCC group; and (5) a 3-percent reduction in 
cost variance, indicating that the proposed severity level splits 
increase the explanatory power of the base MS-DRG in capturing 
differences in expected cost between the proposed MS-DRG severity level 
splits by at least 3 percent and thus improve the overall accuracy of 
the IPPS payment system. The following table illustrates our findings 
for the suggested MS-DRGs with a two-way severity level split.
[GRAPHIC] [TIFF OMITTED] TP02MY24.047

    As a result, for FY 2025, we are proposing to create new MS-DRGs 
447 (Multiple Level Spinal Fusion Except Cervical with MCC) and new MS-
DRG 448 (Multiple Level Spinal Fusion Except Cervical without MCC). We 
are also proposing to revise the title for existing MS-DRGs 459 and 460 
to ``Single Level Spinal Fusion Except Cervical with MCC and without 
MCC'', respectively. This proposal would better differentiate the 
resource utilization, severity of illness and technical complexity 
between single level and multiple level spinal fusions that do not 
include cervical spinal fusions in the logic for case assignment. The 
following table reflects a simulation of the proposed new MS-DRGs.
[GRAPHIC] [TIFF OMITTED] TP02MY24.048

    In conclusion, we are proposing to delete MS-DRGs 453, 454, and 455 
and proposing to create 8 new MS-DRGs. We are proposing to create new 
MS-DRG 426 (Multiple Level Combined Anterior and Posterior Spinal 
Fusion Except Cervical with MCC), MS-DRG 427 (Multiple Level Combined 
Anterior and Posterior Spinal Fusion Except Cervical with CC), MS-DRG 
428 (Multiple Level Combined Anterior and Posterior Spinal Fusion 
Except Cervical without CC/MCC), MS-DRG 402 (Single Level Combined 
Anterior and Posterior Spinal Fusion Except Cervical), MS-DRG 429 
(Combined Anterior and Posterior Cervical Spinal Fusion with MCC), MS-
DRG 430 (Combined Anterior and Posterior Cervical Spinal Fusion without 
MCC), MS-DRG 447 (Multiple Level Spinal Fusion Except Cervical with 
MCC) and MS-DRG 448 (Multiple Level Spinal Fusion Except Cervical 
without MCC) for FY 2025. We are proposing the logic for case 
assignment to these proposed new MS-DRGs as displayed in Table 6P.2d, 
Table 6P.2e, Table 6P.2f, Table 6P.2g, and Table 6P.2h. We are also 
proposing to revise the title for MS-DRGs 459 and

[[Page 35985]]

460 to ``Single Level Spinal Fusion Except Cervical with MCC and 
without MCC'', respectively. Lastly, as discussed in section II.C.14 of 
the preamble of this proposed rule, we are proposing conforming changes 
to the surgical hierarchy for MDC 08.
7. MDC 10 (Endocrine, Nutritional and Metabolic Diseases and 
Disorders): Resection of Right Large Intestine
    We identified an inconsistency in the MDC and MS-DRG assignment of 
procedure codes describing resection of the right large intestine and 
resection of the left large intestine with an open and percutaneous 
endoscopic approach. ICD-10-PCS procedure codes 0DTG0ZZ (Resection of 
left large intestine, open approach) and 0DTG4ZZ (Resection of left 
large intestine, percutaneous endoscopic approach) are currently 
assigned to MDC 10 in MS-DRGs 628, 629, and 630 (Other Endocrine, 
Nutritional and Metabolic O.R. Procedures with MCC, with CC, and 
without CC/MCC, respectively). However, the procedure codes that 
describe resection of the right large intestine with an open or 
percutaneous endoscopic approach, 0DTF0ZZ (Resection of right large 
intestine, open approach) and 0DTF4ZZ (Resection of right large 
intestine, percutaneous endoscopic approach) are not assigned to MDC 10 
in MS-DRGs 628, 629, and 630. To ensure clinical alignment and 
consistency, as well as appropriate MS-DRG assignment, we are proposing 
to add procedure codes 0DTF0ZZ and 0DTF4ZZ to MDC 10 in MS-DRGs 628, 
629, and 630 effective October 1, 2024 for FY 2025.
8. MDC 15 (Newborns and Other Neonates With Conditions Originating in 
Perinatal Period): MS-DRG 795 Normal Newborn
    We received a request to review the GROUPER logic that would 
determine the assignment of cases to MS-DRG 794 (Neonate with Other 
Significant Problems). The requestor stated that it appears that MS-DRG 
794 is the default MS-DRG in MDC 15 (Newborns and Other Neonates with 
Conditions Originating in Perinatal Period), as the GROUPER logic for 
MS-DRG 794 displayed in the ICD-10 MS-DRG Version 41.1 Definitions 
Manual is defined by a ``principal or secondary diagnosis of newborn or 
neonate, with other significant problems, not assigned to DRG 789 
through 793 or 795''. The requestor expressed concern that defaulting 
to MS-DRG 794, instead of MS-DRG 795 (Normal Newborn), for assignment 
of cases in MDC 15 could contribute to overpayments in healthcare by 
not aligning the payment amount to the appropriate level of care in 
newborn cases. The requestor recommended that CMS update the GROUPER 
logic that would determine the assignment of cases to MS-DRGs in MDC 15 
to direct all cases that do not have the diagnoses and procedures as 
specified in the Definitions Manual to instead be grouped to MS-DRG 
795.
    Specifically, the requestor expressed concern that a newborn 
encounter coded with a principal diagnosis code from ICD-10-CM category 
Z38 (Liveborn infants according to place of birth and type of 
delivery), followed by code P05.19 (Newborn small for gestational age, 
other), P59.9 (Neonatal jaundice, unspecified), Q38.1 (Ankyloglossia), 
Q82.5 (Congenital non-neoplastic nevus), or Z23 (Encounter for 
immunization) is assigned to MS-DRG 794. The requestor stated that they 
performed a detailed claim level study, and in their clinical 
assessment, newborn encounters coded with a principal diagnosis code 
from ICD-10-CM category Z38, followed by diagnosis code P05.19, P59.9, 
Q38.1, Q82.5, or Z23 in fact clinically describe normal newborn 
encounters and the case assignment should instead be to MS-DRG 795.
    Our analysis of this grouping issue confirmed that when a principal 
diagnosis code from MDC 15, such as a diagnosis code from category Z38 
(Liveborn infants according to place of birth and type of delivery), is 
reported followed by ICD-10-CM code P05.19 (Newborn small for 
gestational age, other), Q38.1 (Ankyloglossia) or Q82.5 (Congenital 
non-neoplastic nevus), the case is assigned to MS-DRG 794.
    However, as we examined the GROUPER logic that would determine an 
assignment of cases to MS-DRG 795, we noted the ``only secondary 
diagnosis'' list under MS-DRG 795 already includes ICD-10-CM codes 
P59.9 (Neonatal jaundice, unspecified) and Z23 (Encounter for 
immunization). Therefore, when a principal diagnosis code from MDC 15, 
such as a diagnosis code from category Z38 (Liveborn infants according 
to place of birth and type of delivery) is reported, followed by ICD-
10-CM code P59.9 or Z23, the case is currently assigned to MS-DRG 795, 
not MS-DRG 794, as suggested by the requestor. We refer the reader to 
the ICD-10 MS-DRG Version 41.1 Definitions Manual (available on the CMS 
website at: https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps/ms-drg-classifications-and-software) for 
complete documentation of the GROUPER logic for MS-DRGs 794 and 795.
    Next, we reviewed the claims data from the September 2023 update of 
the FY 2023 MedPAR file; however, we found zero cases across MS-DRGs 
794 and 795. We then examined the clinical factors. The description for 
ICD-10-CM diagnosis code P05.19 is ``Newborn small for gestational age, 
other'' and the inclusion term in the ICD-10-CM Tabular List of 
Diseases for this diagnosis code is ``Newborn small for gestational 
age, 2500 grams and over.'' We note that ``small-for-gestational age'' 
is diagnosed by assessing the gestational age and the weight of the 
baby after birth. There is no specific treatment for small-for-
gestational-age newborns. Most newborns who are moderately small for 
gestational age are healthy babies who just happen to be on the smaller 
side. Unless the newborn is born with an infection or has a genetic 
disorder, most small-for-gestational-age newborns have no symptoms and 
catch up in their growth during the first year of life and have a 
normal adult height. Next, ICD-10-CM diagnosis code Q38.1 describes 
ankyloglossia, also known as tongue-tie, which is a condition that 
impairs tongue movement due to a restrictive lingual frenulum. In 
infants, tongue-tie is treated by making a small cut to the lingual 
frenulum to allow the tongue to move more freely. This procedure, 
called a frenotomy, can be done in a healthcare provider's office 
without anesthesia. Newborns generally recover within about a minute of 
the procedure, and pain relief is usually not indicated. Lastly, ICD-
10-CM diagnosis code Q82.5 describes a congenital non-neoplastic nevus. 
A congenital nevus is a type of pigmented birthmark that appears at 
birth or during a baby's first year. Most congenital nevi do not cause 
health problems and may only require future monitoring.
    In reviewing these three ICD-10-CM codes and the conditions they 
describe; we believe these diagnoses generally do not prolong the 
inpatient admission of the newborn and newborns with these diagnoses 
generally receive standard follow-up care after birth. Clinically, we 
agree with the requestor that newborn encounters coded with a principal 
diagnosis code from ICD-10-CM category Z38 (Liveborn infants according 
to place of birth and type of delivery), followed by code P05.19 
(Newborn small for gestational age, other), Q38.1 (Ankyloglossia), or 
Q82.5 (Congenital non-neoplastic nevus) should not map to MS-DRG 794 
(Neonate with Other Significant Problems) and should instead be 
assigned to MS-DRG 795 (Normal

[[Page 35986]]

Newborn). Therefore, for the reasons discussed, we are proposing to 
reassign diagnosis code P05.19 from the ``principal or secondary 
diagnosis'' list under MS-DRG 794 to the ``principal diagnosis'' list 
under MS-DRG 795 (Normal Newborn). We are also proposing to add 
diagnosis codes Q38.1 and Q82.5 to the ``only secondary diagnosis'' 
list under MS-DRG 795 (Normal Newborn). Under this proposal, cases with 
a principal diagnosis described by an ICD-10-CM code from category Z38 
(Liveborn infants according to place of birth and type of delivery), 
followed by codes P05.19, Q38.1, or Q82.5 will be assigned to MS-DRG 
795.
    In response to the recommendation that CMS update the GROUPER logic 
that would determine an assignment of cases to MS-DRGs in MDC 15, we 
agree with the requestor that the GROUPER logic for MS-DRG 794 is 
defined by a ``principal or secondary diagnosis of newborn or neonate, 
with other significant problems, not assigned to DRG 789 through 793 or 
795''. We acknowledge that MS-DRG 794 utilizes ``fall-through'' logic, 
meaning if a diagnosis code is not assigned to any of the other MS-
DRGs, then assignment ``falls-through'' to MS-DRG 794. We have started 
to examine the GROUPER logic that would determine the assignment of 
cases to the MS-DRGs in MDC 15, including MS-DRGs 794 and 795, to 
determine where further refinements could potentially be made to better 
account for differences in clinical complexity and resource 
utilization. However, as we have noted in prior rulemaking (72 FR 
47152), we cannot adopt the same approach to refine the newborn MS-DRGs 
because of the extremely low volume of Medicare patients there are in 
these MS-DRGs. Additional time is needed to fully and accurately 
evaluate cases currently grouping to the MS-DRGs in MDC 15 to consider 
if restructuring the current MS-DRGs would better recognize the 
clinical distinctions of these patient populations. Any proposed 
modifications to these MS-DRGs will be addressed in future rulemaking 
consistent with our annual process.
    As noted earlier, we have started our examination of the GROUPER 
logic that would determine an assignment of cases to MS-DRGs in MDC 15. 
During this review we noted the logic for MS-DRG 795 (Normal Newborn) 
includes five diagnosis codes from ICD-10-CM category Q81 
(Epidermolysis bullosa). We refer the reader to the ICD-10 MS-DRG 
Version 41.1 Definitions Manual (available via on the CMS website at: 
https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps/ms-drg-classifications-and-software) for complete 
documentation of the GROUPER logic for MS-DRG 795. The five diagnosis 
codes and their current MDC and MS-DRG assignments are listed in the 
following table.
[GRAPHIC] [TIFF OMITTED] TP02MY24.049

    We reviewed this grouping issue and noted that epidermolysis 
bullosa (EB) is a group of genetic (inherited) disorders that causes 
skin to be fragile, blister, and tear easily in response to minimal 
friction or trauma. In some cases, blisters form inside the body in 
places such as the mouth, esophagus, other internal organs, or eyes. 
When the blisters heal, they can cause painful scarring. In severe 
cases, the blisters and scars can harm internal organs and tissue 
enough to be fatal. Patients diagnosed with severe cases of EB have a 
life expectancy that ranges from infancy to 30 years of age.
    EB has four primary types: simplex, junctional, dystrophic, and 
Kindler syndrome, and within each type there are various subtypes, 
ranging from mild to severe. A skin biopsy can confirm a diagnosis of 
EB and identify which layers of the skin are affected and determine the 
type of epidermolysis bullosa. Genetic testing may also be ordered to 
diagnose the specific type and subtype of the disease. In caring for 
patients with EB, adaptions may be necessary in the form of handling, 
feeding, dressing, managing pain, and treating wounds caused by the 
blisters and tears. If there is a known diagnosis of EB, but the 
neonate has no physical signs at birth, there will still need to be 
specialty consultation in the inpatient setting or referral for 
outpatient follow-up. We believe the five diagnosis codes from ICD-10-
CM category Q81 (Epidermolysis bullosa) describe conditions that 
require advanced care and resources similar to other conditions already 
assigned to the logic of MS-DRG 794 and MS-DRGs 595 and 596 (Major Skin 
Disorders with MCC and without MCC, respectively), even in cases where 
the type of EB is unspecified.
    Therefore, for clinical consistency, we are proposing to reassign 
ICD-10-CM diagnosis codes Q81.0, Q81.1, Q81.2, Q81.8, and Q81.9 from 
MS-DRGs 606 and 607 in MDC 09 (Diseases and Disorders of the Skin, 
Subcutaneous Tissue and Breast) and MS-DRG 795 (Normal Newborn) in MDC 
15 to MS-DRGs 595 and 596 in MDC 09 and MS-DRG 794 in MDC 15, effective 
October 1, 2024 for FY 2025.
9. MDC 17 (Myeloproliferative Diseases and Disorders, Poorly 
Differentiated Neoplasms): Acute Leukemia
    We identified a replication issue from the ICD-9 based MS-DRGs to 
the ICD-10 based MS-DRGs regarding the assignment of six ICD-10-CM 
diagnosis codes that describe a type of acute leukemia. Under the 
Version 32 ICD-9-CM based MS-DRGs, the ICD-9-CM diagnosis codes as 
shown in the following table were assigned to surgical MS-DRGs 820, 
821, and 822 (Lymphoma and Leukemia with Major O.R. Procedures with 
MCC, with CC, and without CC/MCC, respectively), surgical MS-DRGs 823, 
824, and 825 (Lymphoma and Non-Acute Leukemia with Other Procedures 
with MCC, with CC, and without CC/MCC, respectively), and medical MS-
DRGs 840, 841, and 842 (Lymphoma and Non-Acute Leukemia with MCC, with 
CC, and without CC/MCC, respectively) in MDC 17 (Myeloproliferative 
Diseases and Disorders, Poorly Differentiated Neoplasms). The six ICD-
10-PCS code translations also shown in the following table, that 
provide more detailed and specific information for the ICD-9-CM codes 
reflected, also currently group to MS-DRGs 820, 821, 822, 823, 824, 
825, 840, 841 and 842 in the ICD-10 MS-DRGs Version 41.1. We refer the 
reader to the ICD-10 MS-DRG Definitions Manual Version 41.1 (available 
on the CMS website at: https://www.cms.gov/

[[Page 35987]]

medicare/payment/prospective-payment-systems/acute-inpatient-pps/ms-
drg-classifications-and-software) for complete documentation of the 
GROUPER logic for MS-DRGs 820, 821, 822, 823, 824, 825, 840, 841, and 
842.
[GRAPHIC] [TIFF OMITTED] TP02MY24.050

    During our review of this issue, we noted that under ICD-9-CM, the 
diagnosis codes as reflected in the table did not describe the acuity 
of the diagnosis (for example, acute versus chronic). This is in 
contrast to their six comparable ICD-10-CM code translations listed in 
the previous table that provide more detailed and specific information 
for the ICD-9-CM diagnosis codes and do specify the acuity of the 
diagnoses.
    We note that ICD-10-CM codes C94.20, C94.21, and C94.22 describe 
acute megakaryoblastic leukemia (AMKL), a rare subtype of acute myeloid 
leukemia (AML) that affects megakaryocytes, platelet-producing cells 
that reside in the bone marrow. Similarly, ICD-10-CM codes C94.40, 
C94.41, and C94.42 describe acute panmyelosis with myelofibrosis 
(APMF), a rare form of acute myeloid leukemia characterized by acute 
panmyeloid proliferation with increased blasts and accompanying 
fibrosis of the bone marrow that does not meet the criteria for AML 
with myelodysplasia related changes. As previously mentioned, these six 
diagnosis codes are assigned to MS-DRGs 820, 821, 822, 823, 824, 825, 
840, 841, and 842. The GROUPER logic lists for MS-DRGs 820, 821, and 
822 includes diagnosis codes describing lymphoma and both acute and 
non-acute leukemias, however the logic lists for MS-DRGs 823, 824, 825, 
840, 841, and 842 contain diagnosis codes describing lymphoma and non-
acute leukemias. In our analysis of this grouping issue, we also noted 
that cases reporting a chemotherapy principal diagnosis with a 
secondary diagnosis describing acute megakaryoblastic leukemia or acute 
panmyelosis with myelofibrosis are assigned to MS-DRGs 846, 847, and 
848 (Chemotherapy without Acute Leukemia as Secondary Diagnosis, with 
MCC, with CC, and without CC/MCC, respectively) in Version 41.1.
    Next, we examined claims data from the September 2023 update of the 
FY 2023 MedPAR file for MS-DRG 823, 824, 825, 840, 841, and 842 to 
identify cases reporting one of the six diagnosis codes listed 
previously that describe acute megakaryoblastic leukemia or acute 
panmyelosis with myelofibrosis. We also examined MS-DRGs 846, 847, and 
848 (Chemotherapy without Acute Leukemia as Secondary Diagnosis, with 
MCC, with CC, and without CC/MCC, respectively). Our findings are shown 
in the following tables:
[GRAPHIC] [TIFF OMITTED] TP02MY24.051

    As shown in the table, in MS-DRG 823, we identified a total of 
2,235 cases with an average length of stay of 14 days and average costs 
of $40,587. Of those 2,235 cases, there were two cases reporting a 
diagnosis code that describes acute megakaryoblastic leukemia or acute 
panmyelosis with myelofibrosis, with average costs higher than the 
average costs in the FY 2023 MedPAR file for MS-DRG 823 ($49,600 
compared to $40,587) and a longer average length of stay (31.5 days 
compared to 14 days). We found zero cases in MS-DRG 824 reporting a 
diagnosis code that describes acute megakaryoblastic leukemia or acute 
panmyelosis with myelofibrosis. In MS-DRG 825, we identified a total of 
427 cases with an average length of stay of 2.9 days and average costs 
of $10,959. Of those 427 cases, there was one case reporting a 
diagnosis code that describes acute megakaryoblastic leukemia or acute 
panmyelosis with myelofibrosis, with costs higher than the average 
costs in the FY 2023 MedPAR file for MS-DRG 825 ($17,293 compared to 
$10,959) and a longer length of stay (6 days compared to 2.9 days).

[[Page 35988]]

[GRAPHIC] [TIFF OMITTED] TP02MY24.052

    As shown in the table, in MS-DRG 840, we identified a total of 
7,747 cases with an average length of stay of 9.6 days and average 
costs of $26,215. Of those 7,747 cases, there were 12 cases reporting a 
diagnosis code that describes acute megakaryoblastic leukemia or acute 
panmyelosis with myelofibrosis, with average costs lower than the 
average costs in the FY 2023 MedPAR file for MS-DRG 840 ($21,357 
compared to $26,215) and a shorter average length of stay (8.7 days 
compared to 9.6 days). In MS-DRG 841, we identified a total of 5,019 
cases with an average length of stay of 5.3 days and average costs of 
$13,502. Of those 5,019 cases, there were six cases reporting a 
diagnosis code that describes acute megakaryoblastic leukemia or acute 
panmyelosis with myelofibrosis, with average costs lower than the 
average costs in the FY 2023 MedPAR file for MS-DRG 841 ($6,976 
compared to $13,502) and a shorter average length of stay (2.8 days 
compared to 5.3 days). We found zero cases in MS-DRG 842 reporting a 
diagnosis code that describes acute megakaryoblastic leukemia or acute 
panmyelosis with myelofibrosis.
[GRAPHIC] [TIFF OMITTED] TP02MY24.053

    As shown in the table, in MS-DRG 847, we identified a total of 
7,329 cases with an average length of stay of 4.4 days and average 
costs of $11,250. Of those 7,329 cases, there were two cases reporting 
a chemotherapy principal diagnosis code with a secondary diagnosis code 
that describes acute megakaryoblastic leukemia or acute panmyelosis 
with myelofibrosis, with average costs lower than the average costs in 
the FY 2023 MedPAR file for MS-DRG 840 ($7,569 compared to $11,250) and 
a longer average length of stay (5 days compared to 4.4 days). We found 
zero cases in MS-DRGs 846 and 848 reporting a diagnosis code that 
describes acute megakaryoblastic leukemia or acute panmyelosis with 
myelofibrosis.
    Next, we examined the MS-DRGs within MDC 17. Given that the six 
diagnoses codes describe subtypes of acute myeloid leukemia, we 
determined that the cases reporting a principal diagnosis of acute 
megakaryoblastic leukemia or acute panmyelosis with myelofibrosis would 
more suitably group to medical MS-DRGs 834, 835, and 836 (Acute 
Leukemia without Major O.R. Procedures with MCC, with CC, and without 
CC/MCC, respectively). Similarly, cases reporting a chemotherapy 
principal diagnosis with a secondary diagnosis describing acute 
megakaryoblastic leukemia or acute panmyelosis with myelofibrosis would 
more suitably group to medical MS-DRGs 837, 838, and 839 (Chemotherapy 
with Acute Leukemia as Secondary Diagnosis, or with High Dose 
Chemotherapy Agent with MCC, with CC or High Dose Chemotherapy Agent, 
and without CC/MCC, respectively).
    We then examined claims data from the September 2023 update of the 
FY 2023 MedPAR for MS-DRGs 834, 835, 836, 837, 838, and 839. Our 
findings are shown in the following table.

[[Page 35989]]

[GRAPHIC] [TIFF OMITTED] TP02MY24.054

    While the average costs for all cases in MS-DRGs 834, 835, 836, 
837, 838, and 839 are higher than the average costs of the small number 
of cases reporting a diagnosis code that describes acute 
megakaryoblastic leukemia or acute panmyelosis with myelofibrosis, or 
reporting a chemotherapy principal diagnosis with a secondary diagnosis 
describing acute megakaryoblastic leukemia or acute panmyelosis with 
myelofibrosis, and the average lengths of stay are longer, we note that 
diagnosis codes C94.20, C94.21, C94.22, C94.40, C94.41, and C94.42 
describe types of acute leukemia. For clinical coherence, we believe 
these six diagnosis codes would be more appropriately grouped along 
with other ICD-10-CM diagnosis codes that describe types of acute 
leukemia.
    We reviewed this grouping issue, and our analysis indicates that 
the six diagnosis codes describing the acute megakaryoblastic leukemia 
or acute panmyelosis with myelofibrosis were initially assigned to the 
list of diagnoses in the GROUPER logic for MS-DRGs 823, 824, 825, 840, 
841, and 842 as a result of replication in the transition from ICD-9 to 
ICD-10 based MS-DRGs. We also note that diagnosis codes C94.20, C94.21, 
C94.22, C94.40, C94.41, and C94.42 do not describe non-acute leukemia 
diagnoses.
    Accordingly, because the six diagnosis codes that describe acute 
megakaryoblastic leukemia or acute panmyelosis with myelofibrosis are 
not clinically consistent with non-acute leukemia diagnoses, and it is 
clinically appropriate to reassign these diagnosis codes to be 
consistent with the other diagnosis codes that describe acute leukemias 
in MS-DRGs 834, 835, 836, 837, 838, and 839, we are proposing the 
reassignment of diagnosis codes C94.20, C94.21, C94.22, C94.40, C94.41, 
and C94.42 from MS-DRGs 823, 824 and 825 (Lymphoma and Non-Acute 
Leukemia with Other Procedures with MCC, with CC, and without CC/MCC, 
respectively), and MS-DRGs 840, 841, and 842 (Lymphoma and Non-Acute 
Leukemia with MCC, with CC, and without CC/MCC, respectively) to MS-
DRGs 834, 835, and 836 (Acute Leukemia without Major O.R. Procedures 
with MCC, with CC, and without CC/MCC, respectively) and MS-DRGs 837, 
838, and 839 (Chemotherapy with Acute Leukemia as Secondary Diagnosis, 
or with High Dose Chemotherapy Agent with MCC, with CC or High Dose 
Chemotherapy Agent, and without CC/MCC, respectively) in MDC 17, 
effective FY 2025. Under this proposal, diagnosis codes C94.20, C94.21, 
C94.22, C94.40, C94.41, and C94.42 will continue to be assigned to 
surgical MS-DRGs 820, 821, and 822 (Lymphoma and Leukemia with Major 
O.R. Procedures with MCC, with CC, and without CC/MCC, respectively).
    In our review of the MS-DRGs in MDC 17 for further refinement, we 
next examined the procedures currently assigned to MS-DRGs 820, 821, 
and 822 (Lymphoma and Leukemia with Major O.R. Procedures with MCC, 
with CC, and without CC/MCC, respectively) and MS-DRGs 826, 827, and 
828 (Myeloproliferative Disorders or Poorly Differentiated Neoplasms 
with Major O.R. Procedures with MCC, with CC, and without CC/MCC, 
respectively). We note that the logic for case assignment to MS-DRGs 
820, 821, 822, 826, 827, and 828 is comprised of a logic list entitled 
``Operating Room Procedures'' which is defined by a list of 4,320 ICD-
10-PCS procedure codes, including 90 ICD-10-PCS codes describing bypass 
procedures from the cerebral ventricle to various body parts. We refer 
the reader to the ICD-10 MS-DRG Definitions Manual Version 41.1 
(available on the CMS website at: https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps) for complete 
documentation of the GROUPER logic for MS-DRGs 820, 821, 822, 826, 827, 
and 828.
    In our review of the procedures currently assigned to MS-DRGs 820, 
821, 822, 826, 827, and 828, we noted 12 ICD-10-PCS procedure codes 
that describe bypass procedures from the cerebral ventricle to the 
subgaleal space or cerebral cisterns, such as subgaleal or cisternal 
shunt placement, that are not included in the logic for MS-DRGs 820, 
821, 822, 826, 827, and 828. The 12 procedure codes are listed in the 
following table.

[[Page 35990]]


    A subgaleal shunt consists of a shunt tube with one end in the 
lateral ventricles while the other end is inserted into the subgaleal 
space of the scalp, while a ventriculo-cisternal shunt diverts the 
cerebrospinal fluid flow from one of the lateral ventricles, via a 
ventricular catheter, to the cisterna magna of the posterior fossa. 
Both procedures allow for the drainage of excess cerebrospinal fluid. 
Indications for ventriculosubgaleal or ventriculo-cisternal shunting 
include acute head trauma, subdural hematoma, hydrocephalus, and 
leptomeningeal disease (LMD) in malignancies such as breast cancer, 
lung cancer, melanoma, acute lymphocytic leukemia (ALL) and non-
hodgkin's lymphoma (NHL).
    Recognizing that acute lymphocytic leukemia (ALL) and non-hodgkin's 
lymphoma (NHL) are indications for ventriculosubgaleal or ventriculo-
cisternal shunting, we support adding the 12 ICD-10-PCS codes 
identified in the table to MS-DRGs 820, 821, 822, 826, 827, and 828 in 
MDC 17 for consistency to align with the procedure codes listed in the 
definition of MS-DRGs 820, 821, 822, 826, 827, and 828 and also to 
permit proper case assignment when a principal diagnosis from MDC 17 is 
reported with one of the procedure codes in the table that describes 
bypass procedures from the cerebral ventricle to the subgaleal space or 
cerebral cisterns. Therefore, we are proposing to add the 12 procedure 
codes that describe bypass procedures from the cerebral ventricle to 
the subgaleal space or cerebral cisterns listed previously to MS-DRGs 
820, 821, 822, 826, 827, and 828 in MDC 17 for FY 2025.
    Lastly, in our analysis of the MS-DRGs in MDC 17 for further 
refinement, we noted that the logic for case assignment to medical MS-
DRGs 834, 835, and 836 (Acute Leukemia without Major O.R. Procedures 
with MCC, with CC, and without CC/MCC, respectively) as displayed in 
the ICD-10 MS-DRG Version 41.1 Definitions Manual (available on the CMS 
website at: https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps) is comprised of a logic list entitled 
``Principal Diagnosis'' and is defined by a list of 27 ICD-10-CM 
diagnosis codes describing various types of acute leukemias. When any 
one of the 27 listed diagnosis codes from the ``Principal Diagnosis'' 
logic list is reported as a principal diagnosis, without a procedure 
code designated as an O.R. procedure or without a procedure code 
designated as a non-O.R. procedure that affects the MS-DRG, the case 
results in assignment to MS-DRG 834, 835, or 836 depending on the 
presence of any additional MCC or CC secondary diagnoses. We note 
however, that while not displayed in the ICD-10 MS-DRG Version 41.1 
Definitions Manual, when any one of the 27 listed diagnosis codes from 
the ``Principal Diagnosis'' logic list is reported as a principal 
diagnosis, along with a procedure code designated as an O.R. procedure 
that is not listed in the logic list of MS-DRGs 820, 821, and 822 
(Lymphoma and Leukemia with Major O.R. Procedures with MCC, with CC, 
and without CC/MCC, respectively), the case also results in assignment 
to medical MS-DRG 834, 835, or 836 depending on the presence of any 
additional MCC or CC secondary diagnoses.
    As medical MS-DRG 834, 835, and 836 contains GROUPER logic that 
includes ICD-10-PCS procedure codes designated as O.R. procedures, we 
examined claims data from the September 2023 update of the FY 2023 
MedPAR file for MS-DRG 834, 835, and 836 to identify cases reporting an 
O.R. procedure. Our findings are shown in the following table:
[GRAPHIC] [TIFF OMITTED] TP02MY24.056

    As shown by the table, in MS-DRG 834, we identified a total of 
4,094 cases, with an average length of stay of 16.3 days and average 
costs of $49,986. Of those 4,094 cases, there were 277 cases reporting 
an O.R. procedure, with higher average costs as compared to all cases 
in MS-DRG 834 ($92,246 compared to $49,986), and a longer average 
length of stay (28.2 days compared to 16.3 days). In MS-DRG 835, we 
identified a total of 1,682 cases with an average length of stay of 7.2 
days and average costs of $19,023. Of those 1,682 cases, there were 79 
cases reporting an O.R. procedure, with higher average costs as 
compared to all cases in MS-DRG 835 ($30,771 compared to $19,023), and 
a longer average length of stay (10.4 days compared to 7.2 days). In 
MS-DRG 836, we identified a total of 230 cases with an average length 
of stay of 4 days and average costs of $11,225. Of those 230 cases, 
there were 7 cases reporting an O.R. procedure, with higher average 
costs as compared to all cases in MS-DRG 836 ($17,950 compared to 
$11,225), and a longer average length of stay (5.9 days compared to 4 
days). The data analysis shows that the average costs of cases 
reporting an O.R. procedure are higher than for all cases in their 
respective MS-DRG.
    The data analysis clearly shows that cases reporting a principal 
diagnosis code describing a type of acute leukemia with an ICD-10-PCS 
procedure code designated as O.R. procedure that is not listed in the 
logic list of MS-DRGs 820, 821, and 822 have higher average costs and 
longer lengths of stay compared to all the cases in their assigned MS-
DRG. For these reasons, we are proposing to create a new surgical MS-
DRG for cases reporting a principal diagnosis code describing a type of 
acute leukemia with an O.R. procedure.
    To compare and analyze the impact of our suggested modifications, 
we ran a simulation using the claims data from the September 2023 
update of the FY 2023 MedPAR file. The following table illustrates our 
findings for all 367 cases reporting a principal diagnosis code 
describing a type of acute leukemia with an ICD-10-PCS procedure code 
designated as O.R. procedure that is not listed in the logic list of 
MS-DRGs 820, 821, and 822. We believe the resulting proposed MS-DRG 
assignment, reflecting these modifications, is more

[[Page 35991]]

clinically homogeneous, coherent and better reflects hospital resource 
use.
[GRAPHIC] [TIFF OMITTED] TP02MY24.057

    We applied the criteria to create subgroups in a base MS-DRG as 
discussed in section II.C.1.b. of this FY 2025 IPPS/LTCH PPS proposed 
rule. As shown in the table, we identified a total of 367 cases using 
the claims data from the September 2023 update of the FY 2023 MedPAR 
file, so the criterion that there are at least 500 or more cases in 
each subgroup could not be met. Therefore, for FY 2025, we are not 
proposing to subdivide the proposed new MS DRG for acute leukemia with 
other procedures into severity levels.
    In summary, for FY 2025, we are proposing to create a new base 
surgical MS-DRG for cases reporting a principal diagnosis describing a 
type of acute leukemia with an ICD-10-PCS procedure code designated as 
O.R. procedure that is not listed in the logic list of MS-DRGs 820, 
821, and 822 in MDC 17. The proposed new MS-DRG is proposed new MS-DRG 
850 (Acute Leukemia with Other Procedures). We are proposing to add the 
27 ICD-10-CM diagnosis codes describing various types of acute 
leukemias currently listed in the logic list entitled ``Principal 
Diagnosis'' in MS-DRGs 834, 835, and 836 as well as ICD-10-CM codes 
C94.20, C94.21, C94.22, C94.40, C94.41, and C94.42 discussed earlier in 
this section to the proposed new MS-DRG 850. We are also proposing to 
add the procedure codes from current MS-DRGs 823, 824, and 825 
(Lymphoma and Non-Acute Leukemia with Other Procedures with MCC, with 
CC, and without CC/MCC, respectively) to the proposed new MS-DRG 850. 
We note that in the current logic list of MS-DRGs 823, 824, and 825 
there are 189 procedure codes describing stereotactic radiosurgery of 
various body parts that are designated as non-O.R. procedures affecting 
the MS-DRG, therefore, as part of the logic for new MS-DRG 850, we are 
also proposing to designate these 189 codes as non-O.R. procedures 
affecting the MS-DRG.
    In addition, we are proposing to revise the titles for MS-DRGs 834, 
835, and 836 by deleting the reference to ``Major O.R. Procedures'' in 
the title. Specifically, we are proposing to revise the titles of 
medical MS-DRGs 834, 835, and 836 from ``Acute Leukemia without Major 
O.R. Procedures with MCC, with CC, and without CC/MCC'', respectively 
to ``Acute Leukemia with MCC, with CC, and without CC/MCC'', 
respectively to better reflect the GROUPER logic that will no longer 
include ICD-10-PCS procedure codes designated as O.R. procedures. We 
note that discussion of the surgical hierarchy for the proposed 
modifications is discussed in section II.C.15. of this proposed rule.
10. Review of Procedure Codes in MS-DRGs 981 Through 983 and 987 
Through 989
    We annually conduct a review of procedures producing assignment to 
MS-DRGs 981 through 983 (Extensive O.R. Procedure Unrelated to 
Principal Diagnosis with MCC, with CC, and without CC/MCC, 
respectively) or MS-DRGs 987 through 989 (Non-Extensive O.R. Procedure 
Unrelated to Principal Diagnosis with MCC, with CC, and without CC/MCC, 
respectively) on the basis of volume, by procedure, to see if it would 
be appropriate to move cases reporting these procedure codes out of 
these MS-DRGs into one of the surgical MS-DRGs for the MDC into which 
the principal diagnosis falls. The data are arrayed in two ways for 
comparison purposes. We look at a frequency count of each major 
operative procedure code. We also compare procedures across MDCs by 
volume of procedure codes within each MDC. We use this information to 
determine which procedure codes and diagnosis codes to examine.
    We identify those procedures occurring in conjunction with certain 
principal diagnoses with sufficient frequency to justify adding them to 
one of the surgical MS-DRGs for the MDC in which the diagnosis falls. 
We also consider whether it would be more appropriate to move the 
principal diagnosis codes into the MDC to which the procedure is 
currently assigned.
    Based on the results of our review of the claims data from the 
September 2023 update of the FY 2023 MedPAR file of cases found to 
group to MS-DRGs 981 through 983 or MS-DRGs 987 through 989, we did not 
identify any cases for reassignment and are not proposing to move any 
cases from MS-DRGs 981 through 983 or MS-DRGs 987 through 989 into a 
surgical MS-DRGs for the MDC into which the principal diagnosis or 
procedure is assigned.
    In addition to the internal review of procedures producing 
assignment to MS-DRGs 981 through 983 or MS-DRGs 987 through 989, we 
also consider requests that we receive to examine cases found to group 
to MS-DRGs 981 through 983 or MS-DRGs 987 through 989 to determine if 
it would be appropriate to add procedure codes to one of the surgical 
MS-DRGs for the MDC into which the principal diagnosis falls or to move 
the principal diagnosis to the surgical MS-DRGs to which the procedure 
codes are assigned. We did not receive any requests suggesting 
reassignment.
    We also review the list of ICD-10-PCS procedures that, when in 
combination with their principal diagnosis code, result in assignment 
to MS DRGs 981 through 983, or 987 through 989, to ascertain whether 
any of those procedures should be reassigned from one of those two 
groups of MS DRGs to the other group of MS DRGs based on average costs 
and the length of stay. We look at the data for trends such as shifts 
in treatment practice or reporting practice that would make the 
resulting MS DRG assignment illogical. If we find these shifts, we 
would propose to move cases to keep the MS DRGs clinically similar or 
to provide payment for the cases in a similar manner. Generally, we 
move only those procedures for which we have an adequate number of 
discharges to analyze the data.
    Additionally, we also consider requests that we receive to examine 
cases found to group to MS-DRGs 981 through 983 or MS-DRGs 987 through 
989 to determine if it would be appropriate for the cases to be 
reassigned from one of the MS-DRG groups to the other. Based on the 
results of our review of the claims data from the September 2023 update 
of the FY 2023 MedPAR file we did not identify any cases for 
reassignment. We also did not receive any requests suggesting 
reassignment. Therefore, for FY 2025 we are not proposing to move any 
cases reporting procedure codes from MS-

[[Page 35992]]

DRGs 981 through 983 to MS-DRGs 987 through 989 or vice versa.
11. Operating Room (O.R.) and Non-O.R. Procedures
a. Background
    Under the IPPS MS-DRGs (and former CMS MS-DRGs), we have a list of 
procedure codes that are considered operating room (O.R.) procedures. 
Historically, we developed this list using physician panels that 
classified each procedure code based on the procedure and its effect on 
consumption of hospital resources. For example, generally the presence 
of a surgical procedure which required the use of the operating room 
would be expected to have a significant effect on the type of hospital 
resources (for example, operating room, recovery room, and anesthesia) 
used by a patient, and therefore, these patients were considered 
surgical. Because the claims data generally available do not precisely 
indicate whether a patient was taken to the operating room, surgical 
patients were identified based on the procedures that were performed.
    Generally, if the procedure was not expected to require the use of 
the operating room, the patient would be considered medical (non-O.R.).
    Currently, each ICD-10-PCS procedure code has designations that 
determine whether and in what way the presence of that procedure on a 
claim impacts the MS-DRG assignment. First, each ICD-10-PCS procedure 
code is either designated as an O.R. procedure for purposes of MS-DRG 
assignment (``O.R. procedures'') or is not designated as an O.R. 
procedure for purposes of MS-DRG assignment (``non-O.R. procedures''). 
Second, for each procedure that is designated as an O.R. procedure, 
that O.R. procedure is further classified as either extensive or non-
extensive. Third, for each procedure that is designated as a non-O.R. 
procedure, that non-O.R. procedure is further classified as either 
affecting the MS-DRG assignment or not affecting the MS-DRG assignment. 
We refer to these designations that do affect MS-DRG assignment as 
``non O.R. affecting the MS-DRG.'' For new procedure codes that have 
been finalized through the ICD-10 Coordination and Maintenance 
Committee meeting process and are proposed to be classified as
    O.R. procedures or non-O.R. procedures affecting the MS-DRG, we 
recommend the MS-DRG assignment which is then made available in 
association with the proposed rule (Table 6B.--New Procedure Codes) and 
subject to public comment. These proposed assignments are generally 
based on the assignment of predecessor codes or the assignment of 
similar codes. For example, we generally examine the MS-DRG assignment 
for similar procedures, such as the other approaches for that 
procedure, to determine the most appropriate MS-DRG assignment for 
procedures proposed to be newly designated as O.R. procedures. As 
discussed in section II.C.13 of the preamble of this proposed rule, we 
are making Table 6B.--New Procedure Codes--FY 2025 available on the CMS 
website at: https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps.html. We also refer readers to the ICD-10 
MS-DRG Version 41.1 Definitions Manual at: https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps/ms-drg-classifications-and-software.html for detailed information 
regarding the designation of procedures as O.R. or non-O.R. (affecting 
the MS-DRG) in Appendix E--Operating Room Procedures and Procedure 
Code/MS-DRG Index.
    In the FY 2020 IPPS/LTCH PPS proposed rule, we stated that, given 
the long period of time that has elapsed since the original O.R. 
(extensive and non-extensive) and non-O.R. designations were 
established, the incremental changes that have occurred to these O.R. 
and non-O.R. procedure code lists, and changes in the way inpatient 
care is delivered, we plan to conduct a comprehensive, systematic 
review of the ICD-10-PCS procedure codes. This will be a multiyear 
project during which we will also review the process for determining 
when a procedure is considered an operating room procedure. For 
example, we may restructure the current O.R. and non-O.R. designations 
for procedures by leveraging the detail that is now available in the 
ICD-10 claims data. We refer readers to the discussion regarding the 
designation of procedure codes in the FY 2018 IPPS/LTCH PPS final rule 
(82 FR 38066) where we stated that the determination of when a 
procedure code should be designated as an O.R. procedure has become a 
much more complex task. This is, in part, due to the number of various 
approaches available in the ICD-10-PCS classification, as well as 
changes in medical practice. While we have typically evaluated 
procedures on the basis of whether or not they would be performed in an 
operating room, we believe that there may be other factors to consider 
with regard to resource utilization, particularly with the 
implementation of ICD-10.
    We discussed in the FY 2020 IPPS/LTCH PPS proposed rule that as a 
result of this planned review and potential restructuring, procedures 
that are currently designated as O.R. procedures may no longer warrant 
that designation, and conversely, procedures that are currently 
designated as non-O.R. procedures may warrant an O.R. type of 
designation. We intend to consider the resources used and how a 
procedure should affect the MS-DRG assignment. We may also consider the 
effect of specific surgical approaches to evaluate whether to subdivide 
specific MS-DRGs based on a specific surgical approach. We stated we 
plan to utilize our available MedPAR claims data as a basis for this 
review and the input of our clinical advisors. As part of this 
comprehensive review of the procedure codes, we also intend to evaluate 
the MS-DRG assignment of the procedures and the current surgical 
hierarchy because both of these factor into the process of refining the 
ICD-10 MS-DRGs to better recognize complexity of service and resource 
utilization.
    In the FY 2021 IPPS/LTCH PPS final rule (85 FR 58540 through 
58541), we provided a summary of the comments we had received in 
response to our request for feedback on what factors or criteria to 
consider in determining whether a procedure is designated as an O.R. 
procedure in the ICD-10-PCS classification system for future 
consideration. We also stated that in consideration of the PHE, we 
believed it may be appropriate to allow additional time for the claims 
data to stabilize prior to selecting the timeframe to analyze for this 
review.
    We stated in the FY 2024 IPPS/LTCH PPS final rule (88 FR 58749) 
that we continue to believe additional time is necessary as we continue 
to develop our process and methodology. Therefore, we stated we will 
provide more detail on this analysis and the methodology for conducting 
this review in future rulemaking. In response to this discussion in the 
FY 2024 IPPS/LTCH PPS final rule, we received a comment by the October 
20, 2023 deadline. The commenter acknowledged that there is no easy 
rule that would allow CMS to designate certain surgeries as ``non-
O.R.'' procedures. The commenter stated that they believed that open 
procedures should always be designated O.R. procedures and approaches 
other than open should not be a sole factor in designating a procedure 
as non-O.R. as some minimally-invasive procedures using a percutaneous 
endoscopic approach require more training,

[[Page 35993]]

specialized equipment, time, and resources than traditional open 
procedures. In addition, the commenter stated that whether a procedure 
is frequently or generally performed in the outpatient setting should 
not be used for determination of O.R. vs non-O.R. designation and noted 
that a surgery that can be performed in the outpatient setting for a 
clinically stable patient may not be able to be safely performed on a 
patient who is clinically unstable. The commenter also asserted that 
for procedures that can be performed in various locations within the 
hospital, that is, bedside vs operating room, there should be a 
mechanism to differentiate the setting of the procedure to determine 
the MS-DRG assignment as in the commenter's assessment, the ICD-10 
classification does not provide a way to indicate the severity of 
certain conditions, or the complexity of procedures performed.
    CMS appreciates the commenter's feedback and recommendations as to 
factors to consider in evaluating O.R. designations. We agree with the 
commenter and believe that there may be other factors to consider with 
regard to resource utilization. As discussed in the FY 2024 IPPS/LTCH 
PPS final rule, we have signaled in prior rulemaking that the 
designation of an O.R. procedure encompasses more than the physical 
location of the hospital room in which the procedure may be performed; 
in other words, the performance of a procedure in an operating room is 
not the sole determining factor we will consider as we examine the 
designation of a procedure in the ICD-10-PCS classification system. We 
are exploring alternatives on how we may restructure the current O.R. 
and non-O.R. designations for procedures by leveraging the detail that 
is available in the ICD-10 claims data. We are considering the feedback 
received on what factors and/or criteria to consider in determining 
whether a procedure is designated as an O.R. procedure in the ICD-10-
PCS classification system as continue to develop our process and 
methodology, and will provide more detail on this analysis and the 
methodology for conducting this comprehensive review in future 
rulemaking. We encourage the public to continue to submit comments on 
any other factors to consider in our refinement efforts to recognize 
and differentiate consumption of resources for the ICD-10 MS-DRGs for 
consideration.
    For this FY 2025 IPPS/LTCH PPS proposed rule, we did not receive 
any requests regarding changing the designation of specific ICD-10-PCS 
procedure codes from non-O.R. to O.R. procedures, or to change the 
designation from O.R. procedures to non-O.R. procedures by the October 
20, 2023 deadline. In this section of the proposed rule, we discuss the 
proposals we are making based on our internal review and analysis and 
we discuss the process that was utilized for evaluating each procedure 
code. For each procedure, we considered--
     Whether the procedure would typically require the 
resources of an operating room;
     Whether it is an extensive or a non-extensive procedure; 
and
     To which MS-DRGs the procedure should be assigned.
    We note that many MS-DRGs require the presence of any O.R. 
procedure. As a result, cases with a principal diagnosis associated 
with a particular MS-DRG would, by default, be grouped to that MS-DRG. 
Therefore, we do not list these MS-DRGs in our discussion in this 
section of this proposed rule. Instead, we only discuss MS-DRGs that 
require explicitly adding the relevant procedure codes to the GROUPER 
logic in order for those procedure codes to affect the MS-DRG 
assignment as intended.
    For procedures that would not typically require the resources of an 
operating room, we determined if the procedure should affect the MS-DRG 
assignment. In cases where we are proposing to change the designation 
of procedure codes from non-O.R. procedures to O.R. procedures, we also 
are proposing one or more MS-DRGs with which these procedures are 
clinically aligned and to which the procedure code would be assigned.
    In addition, cases that contain O.R. procedures will map to MS-DRGs 
981, 982, or 983 (Extensive O.R. Procedure Unrelated to Principal 
Diagnosis with MCC, with CC, and without CC/MCC, respectively) or MS-
DRGs 987, 988, or 989 (Non-Extensive O.R. Procedure Unrelated to 
Principal Diagnosis with MCC, with CC, and without CC/MCC, 
respectively) when they do not contain a principal diagnosis that 
corresponds to one of the MDCs to which that procedure is assigned. 
These procedures need not be assigned to MS-DRGs 981 through 989 in 
order for this to occur. Therefore, we did not specifically address 
that aspect in summarizing the proposals we are making based on our 
internal review and analysis in this section of this proposed rule.
b. Non-O.R. Procedures to O.R. Procedures
(1) Laparoscopic Biopsy of Intestinal Body Parts
    During our review, we noted inconsistencies in how procedures 
involving laparoscopic excisions of intestinal body parts are 
designated. Procedure codes describing the laparoscopic excision of 
intestinal body parts differ by qualifier. ICD-10-PCS procedure codes 
describing excisions of intestinal body parts with the diagnostic 
qualifier ``X'', are used to report these procedures when performed for 
diagnostic purposes. We identified the following five related codes:
[GRAPHIC] [TIFF OMITTED] TP02MY24.058

    We noted the ICD-10-PCS procedure codes describing the laparoscopic 
excision of intestinal body parts for diagnostic purposes listed 
previously have been assigned different attributes in terms of 
designation as an O.R. or Non-O.R. procedure when compared to similar 
procedures describing the laparoscopic excisions of intestinal body 
parts for nondiagnostic purposes. In the ICD-10 MS-DRGs Version 41, 
these ICD-10-PCS codes are currently recognized as non-O.R. procedures 
for purposes of MS-DRG assignment, while similar excision of intestinal 
body part procedure codes with the same approach but different 
qualifiers are recognized as O.R. procedures.
    Upon further review and consideration, we believe that procedure 
codes 0DBF4ZX, 0DBG4ZX, 0DBL4ZX, 0DBM4ZX and 0DBN4ZX describing a 
laparoscopic excision of an intestinal body parts for diagnostic

[[Page 35994]]

purposes warrant designation as an O.R. procedures consistent with 
other laparoscopic excision procedures performed on the same intestinal 
body parts for nondiagnostic purposes. We also believe it is clinically 
appropriate for these procedures to group to the same MS-DRGs as the 
procedures describing excision procedures performed on the intestinal 
body parts for nondiagnostic purposes. Therefore, we are proposing to 
add procedure codes 0DBF4ZX, 0DBG4ZX, 0DBL4ZX, 0DBM4ZX and 0DBN4ZX to 
the FY 2025 ICD-10 MS-DRG Version 42 Definitions Manual in Appendix E--
Operating Room Procedures and Procedure Code/MS-DRG Index as O.R. 
procedures assigned to MS-DRG 264 (Other Circulatory System O.R. 
Procedures) in MDC 05 (Diseases and Disorders of the Circulatory 
System); MS-DRGs 329, 330, and 331 (Major Small and Large Bowel 
Procedures, with MCC, with CC, and without CC/MCC, respectively) in MDC 
06 (Diseases and Disorders of the Digestive System); MS-DRGs 820, 821, 
and 822 (Lymphoma and Leukemia with Major O.R. Procedures with MCC, CC, 
without CC/MCC, respectively) and MS-DRGS 826, 827, and 828 
(Myeloproliferative Disorders or Poorly Differentiated Neoplasms with 
Major O.R. Procedures with MCC, with CC, and without CC/MCC, 
respectively) in MDC 17 (Myeloproliferative Diseases and Disorders, 
Poorly Differentiated Neoplasms); MS-DRGs 907, 908, and 909 (Other O.R. 
Procedures for Injuries with MCC, with CC, and without CC/MCC, 
respectively) in MDC 21 (Injuries, Poisonings and Toxic Effects of 
Drugs); and MS-DRGs 957, 958, and 959 (Other O.R. Procedures for 
Multiple Significant Trauma with MCC, with CC, and without CC/MCC, 
respectively) in MDC 24 (Multiple Significant Trauma).
(2) Laparoscopic Biopsy of Gallbladder and Pancreas
    During our review, we noted inconsistencies in how procedures 
involving laparoscopic excisions of gallbladder or pancreas are 
designated. Procedure codes describing the laparoscopic excision of the 
gallbladder or pancreas differ by qualifier. The ICD-10-PCS procedure 
code describing an excision of the gallbladder and the procedure code 
describing an excision of the pancreas with the diagnostic qualifier 
``X'', are used to report these procedures when performed for 
diagnostic purposes. We identified the following two related codes:
[GRAPHIC] [TIFF OMITTED] TP02MY24.059

    We noted the ICD-10-PCS procedure codes describing the laparoscopic 
excision of the gallbladder or the pancreas for diagnostic purposes 
listed previously have been assigned different attributes in terms of 
designation as an O.R. or a Non-O.R. procedure when compared to similar 
procedures describing the laparoscopic excisions of the gallbladder or 
the pancreas for nondiagnostic purposes. In the ICD-10 MS-DRGs Version 
41, these ICD-10-PCS codes are currently recognized as non-O.R. 
procedures for purposes of MS-DRG assignment, while similar excision of 
the gallbladder or the pancreas procedure codes with the same approach 
but different qualifiers are recognized as O.R. procedures.
    Upon further review and consideration, we believe that procedure 
code 0FB44ZX describing a laparoscopic excision of the gallbladder for 
diagnostic purposes and procedure code 0FBG4ZX describing a 
laparoscopic excision of the pancreas for diagnostic purposes both 
warrant designation as an O.R. procedure consistent with other 
laparoscopic excision procedures performed on the same body parts for 
nondiagnostic purposes. We also believe it is clinically appropriate 
for these procedures to group to the same MS-DRGs as the procedures 
describing excision procedures performed on the gallbladder or pancreas 
for nondiagnostic purposes. Therefore, we are proposing to add 
procedure code 0FB44ZX to the FY 2025 ICD-10 MS-DRG Version 42 
Definitions Manual in Appendix E--Operating Room Procedures and 
Procedure Code/MS-DRG Index as an O.R. procedure assigned to MS-DRGs 
411, 412, and 413 (Cholecystectomy with C.D.E., with MCC, with CC, and 
without CC/MCC, respectively) and MS-DRGs 417, 418, and 419 
(Laparoscopic Cholecystectomy without C.D.E., with MCC, with CC, and 
without CC/MCC, respectively) in MDC 07 (Diseases and Disorders of the 
Hepatobiliary System and Pancreas); MS-DRGs 820, 821, and 822 (Lymphoma 
and Leukemia with Major O.R. Procedures with MCC, with CC, and without 
CC/MCC, respectively) and MS-DRGS 826, 827, and 828 (Myeloproliferative 
Disorders or Poorly Differentiated Neoplasms with Major O.R. Procedures 
with MCC, with CC, and without CC/MCC, respectively) in MDC 17 
(Myeloproliferative Diseases and Disorders, Poorly Differentiated 
Neoplasms); MS-DRGs 907, 908, and 909 (Other O.R. Procedures for 
Injuries with MCC, with CC, and without CC/MCC, respectively) in MDC 21 
(Injuries, Poisonings and Toxic Effects of Drugs); and MS-DRGs 957, 
958, and 959 (Other O.R. Procedures for Multiple Significant Trauma 
with MCC, with CC, and without CC/MCC, respectively) in MDC 24 
(Multiple Significant Trauma).
    We are also proposing to add procedure code 0FBG4ZX to the FY 2025 
ICD-10 MS-DRG Version 42 Definitions Manual in Appendix E--Operating 
Room Procedures and Procedure Code/MS-DRG Index as an O.R. procedure 
assigned to MS-DRGs 405, 406, and 407 (Pancreas, Liver and Shunt 
Procedures, with MCC, with CC, and without CC/MCC, respectively) in MDC 
06 (Diseases and Disorders of the Digestive System); MS-DRGs 628, 629 
and 630 (Other Endocrine, Nutritional and Metabolic O.R. Procedures 
with MCC, with CC, and without CC/MCC, respectively) in MDC 10 
(Endocrine, Nutritional and Metabolic Diseases and Disorders); MS-DRGs 
907, 908, and 909 (Other O.R. Procedures for Injuries with MCC, with 
CC, and without CC/MCC, respectively) in MDC 21 (Injuries, Poisonings 
and Toxic Effects of Drugs); and MS-DRGs 957, 958, and 959 (Other O.R. 
Procedures for Multiple Significant Trauma with MCC, with CC, and 
without CC/MCC, respectively) in MDC 24 (Multiple Significant Trauma).
12. Proposed Changes to the MS-DRG Diagnosis Codes for FY 2025
a. Background of the CC List and the CC Exclusions List
    Under the IPPS MS-DRG classification system, we have developed a 
standard list of diagnoses that are considered CCs. Historically, we 
developed this list using physician panels that classified each 
diagnosis code based on whether the diagnosis, when present as a 
secondary condition, would be considered a substantial complication or 
comorbidity. A substantial complication or comorbidity was defined as a 
condition that, because of its presence with a specific principal

[[Page 35995]]

diagnosis, would cause an increase in the length-of-stay by at least 1 
day in at least 75 percent of the patients. However, depending on the 
principal diagnosis of the patient, some diagnoses on the basic list of 
complications and comorbidities may be excluded if they are closely 
related to the principal diagnosis. In FY 2008, we evaluated each 
diagnosis code to determine its impact on resource use and to determine 
the most appropriate CC subclassification (NonCC, CC, or MCC) 
assignment. We refer readers to sections II.D.2. and 3. of the preamble 
of the FY 2008 IPPS final rule with comment period for a discussion of 
the refinement of CCs in relation to the MS DRGs we adopted for FY 2008 
(72 FR 47152 through 47171).
b. Overview of Comprehensive CC/MCC Analysis
    In the FY 2008 IPPS/LTCH PPS final rule (72 FR 47159), we described 
our process for establishing three different levels of CC severity into 
which we would subdivide the diagnosis codes. The categorization of 
diagnoses as a MCC, a CC, or a NonCC was accomplished using an 
iterative approach in which each diagnosis was evaluated to determine 
the extent to which its presence as a secondary diagnosis resulted in 
increased hospital resource use. We refer readers to the FY 2008 IPPS/
LTCH PPS final rule (72 FR 47159) for a complete discussion of our 
approach. Since the comprehensive analysis was completed for FY 2008, 
we have evaluated diagnosis codes individually when assigning severity 
levels to new codes and when receiving requests to change the severity 
level of specific diagnosis codes.
    We noted in the FY 2020 IPPS/LTCH PPS proposed rule (84 FR 19235 
through 19246) that with the transition to ICD-10-CM and the 
significant changes that have occurred to diagnosis codes since the FY 
2008 review, we believed it was necessary to conduct a comprehensive 
analysis once again. Based on this analysis, we proposed changes to the 
severity level designations for 1,492 ICD-10-CM diagnosis codes and 
invited public comments on those proposals. As summarized in the FY 
2020 IPPS/LTCH PPS final rule, many commenters expressed concern with 
the proposed severity level designation changes overall and recommended 
that CMS conduct further analysis prior to finalizing any proposals. 
After careful consideration of the public comments we received, as 
discussed further in the FY 2020 IPPS/LTCH PPS final rule, we generally 
did not finalize our proposed changes to the severity designations for 
the ICD-10-CM diagnosis codes, other than the changes to the severity 
level designations for the diagnosis codes in category Z16 (Resistance 
to antimicrobial drugs) from a NonCC to a CC. We stated that postponing 
adoption of the proposed comprehensive changes in the severity level 
designations would allow further opportunity to provide additional 
background to the public on the methodology utilized and clinical 
rationale applied across diagnostic categories to assist the public in 
its review. We refer readers to the FY 2020 IPPS/LTCH PPS final rule 
(84 FR 42150 through 42152) for a complete discussion of our response 
to public comments regarding the proposed severity level designation 
changes for FY 2020.
    As discussed in the FY 2021 IPPS/LTCH PPS proposed rule (85 FR 
32550), to provide the public with more information on the CC/MCC 
comprehensive analysis discussed in the FY 2020 IPPS/LTCH PPS proposed 
and final rules, CMS hosted a listening session on October 8, 2019. The 
listening session included a review of this methodology utilized to 
mathematically measure the impact on resource use. We refer readers to 
https://www.cms.gov/Outreach-and-Education/Outreach/OpenDoorForums/Downloads/10082019ListingSessionTrasncriptandQandAsandAudioFile.zip for 
the transcript and audio file of the listening session. We also refer 
readers to https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps/ms-drg-classifications-and-software for the 
supplementary file containing the mathematical data generated using 
claims from the FY 2018 MedPAR file describing the impact on resource 
use of specific ICD-10-CM diagnosis codes when reported as a secondary 
diagnosis that was made available for the listening session.
    In the FY 2021 IPPS/LTCH PPS final rule (85 FR 58550 through 
58554), we discussed our plan to continue a comprehensive CC/MCC 
analysis, using a combination of mathematical analysis of claims data 
as discussed in the FY 2020 IPPS/LTCH PPS proposed rule (84 FR 19235) 
and the application of nine guiding principles and plan to present the 
findings and proposals in future rulemaking. The nine guiding 
principles are as follows:
     Represents end of life/near death or has reached an 
advanced stage associated with systemic physiologic decompensation and 
debility.
     Denotes organ system instability or failure.
     Involves a chronic illness with susceptibility to 
exacerbations or abrupt decline.
     Serves as a marker for advanced disease states across 
multiple different comorbid conditions.
     Reflects systemic impact.
     Post-operative/post-procedure condition/complication 
impacting recovery.
     Typically requires higher level of care (that is, 
intensive monitoring, greater
    number of caregivers, additional testing, intensive care unit care, 
extended length of stay).
     Impedes patient cooperation or management of care or both.
     Recent (last 10 years) change in best practice, or in 
practice guidelines and review of the extent to which these changes 
have led to concomitant changes in expected resource use.
    We refer readers to the FY 2021 IPPS/LTCH PPS final rule for a 
complete summation of the comments we received for each of the nine 
guiding principles and our responses to those comments. We note that 
since the FY 2021 IPPS/LTCH PPS final rule we have continued to solicit 
feedback regarding the nine guiding principles, as well as other 
possible ways we can incorporate meaningful indicators of clinical 
severity. We have encouraged the public to provide a detailed 
explanation of how applying a suggested concept or principle would 
ensure that the severity designation appropriately reflects resource 
use for any diagnosis code when providing feedback or comments. In the 
FY 2024 IPPS/LTCH PPS proposed rule (88 FR 26748 through 26750) we 
illustrated how the nine guiding principles might be applied in 
evaluating changes to the severity designations of diagnosis codes in 
our discussion of our proposed changes to the severity level 
designation for certain diagnosis codes that describe homelessness. 
Since the FY 2021 IPPS/LTCH PPS final rule, we have not received any 
additional feedback or comments on the nine guiding principles; 
therefore, we are proposing to finalize the nine guiding principles as 
listed previously in this FY 2025 IPPS/LTCH PPS proposed rule. Under 
this proposal, our evaluations to determine the extent to which the 
presence of a diagnosis code as a secondary diagnosis results in 
increased hospital resource use will include a combination of 
mathematical analysis of claims data as discussed in the FY 2020 IPPS/
LTCH PPS proposed rule (84 FR 19235) and the application of the nine 
guiding principles.

[[Page 35996]]

    In the FY 2022 IPPS/LTCH PPS proposed rule (86 FR 25175 through 
25180), as another interval step in our comprehensive review of the 
severity designations of ICD-10-CM diagnosis codes, we requested public 
comments on a potential change to the severity level designations for 
``unspecified'' ICD-10-CM diagnosis codes that we were considering 
adopting for FY 2022. Specifically, we noted we were considering 
changing the severity level designation of ``unspecified'' diagnosis 
codes to a NonCC where there are other codes available in that code 
subcategory that further specify the anatomic site. As summarized in 
the FY 2022 IPPS/LTCH PPS final rule, many commenters expressed concern 
with the potential severity level designation changes overall and 
recommended that CMS delay any possible change to the designation of 
these codes to give hospitals and their physicians time to prepare. 
After careful consideration of the public comments we received, we 
maintained the severity level designation of the ``unspecified'' 
diagnosis codes currently designated as a CC or MCC where there are 
other codes available in that code subcategory that further specify the 
anatomic site for FY 2022. We refer readers to the FY 2022 IPPS/LTCH 
PPS final rule (86 FR 44916 through 44926) for a complete discussion of 
our response to public comments regarding the potential severity level 
designation changes. Instead, for FY 2022, we finalized a new Medicare 
Code Editor (MCE) code edit for ``unspecified'' codes, effective with 
discharges on and after April 1, 2022. We stated we believe finalizing 
this new edit would provide additional time for providers to be 
educated while not affecting the payment the provider is eligible to 
receive. We refer the reader to section II.D.14.e. of the FY 2022 IPPS/
LTCH PPS final rule (86 FR 44940 through 44943) for the complete 
discussion.
    As discussed in the FY 2023 IPPS/LTCH PPS final rule (87 FR 48866), 
we stated that as the new unspecified edit became effective beginning 
with discharges on and after April 1, 2022, we believed it was 
appropriate to not propose to change the designation of any ICD-10-CM 
diagnosis codes, including the unspecified codes that are subject to 
the ``Unspecified Code'' edit, as we continue our comprehensive CC/MCC 
analysis to allow interested parties the time needed to become 
acclimated to the new edit.
    In the FY 2023 IPPS/LTCH proposed rule (87 FR 28177 through 28181), 
we also requested public comments on how the reporting of diagnosis 
codes in categories Z55-Z65 might improve our ability to recognize 
severity of illness, complexity of illness, and/or utilization of 
resources under the MS-DRGs. Consistent with the Administration's goal 
of advancing health equity for all, including members of historically 
underserved and under-resourced communities, as described in the 
President's January 20, 2021 Executive Order 13985 on ``Advancing 
Racial Equity and Support for Underserved Communities Through the 
Federal Government,'' \4\ we stated we were also interested in 
receiving feedback on how we might otherwise foster the documentation 
and reporting of the diagnosis codes describing social and economic 
circumstances to more accurately reflect each health care encounter and 
improve the reliability and validity of the coded data including in 
support of efforts to advance health equity.

    We noted that social determinants of health (SDOH) are the 
conditions in the environments where people are born, live, learn, 
work, play, worship, and age that affect a wide range of health, 
functioning, and quality-of-life outcomes and risks.\5\ The subset of Z 
codes that describe the social determinants of health are found in 
categories Z55-Z65 (Persons with potential health hazards related to 
socioeconomic and psychosocial circumstances). These codes describe a 
range of issues related--but not limited--to education and literacy, 
employment, housing, ability to obtain adequate amounts of food or safe 
drinking water, and occupational exposure to toxic agents, dust, or 
radiation.

---------------------------------------------------------------------------

    We received numerous public comments that expressed a variety of 
views on our comment solicitation, including many comments that were 
supportive, and others that offered specific suggestions for our 
consideration in future rulemaking. Many commenters applauded CMS' 
efforts to encourage documentation and reporting of SDOH diagnosis 
codes given the impact that social risks can have on health outcomes. 
These commenters stated that it is critical that physicians, other 
health care professionals, and facilities recognize the impact SDOH 
have on the health of their patients. Many commenters also stated that 
the most immediate and important action CMS could take to increase the 
use of SDOH Z codes is to finalize the evidence-based ``Screening for 
Social Drivers of Health'' and ``Screen Positive Rate for Social 
Drivers of Health'' measures proposed to be adopted in the Hospital 
Inpatient Quality Reporting (IQR) Program. In the FY 2023 IPPS/LTCH PPS 
final rule (87 FR 49202 through 49220), CMS finalized the ``Screening 
for Social Drivers of Health'' and ``Screen Positive Rate for Social 
Drivers of Health'' measures in the Hospital Inpatient Quality 
Reporting (IQR) Program. We refer readers to the FY 2023 IPPS/LTCH PPS 
final rule (87 FR 48867 through 48872) for the complete discussion of 
the public comments received regarding the request for information on 
SDOH diagnosis codes.
    As discussed in the FY 2024 IPPS/LTCH PPS final rule (88 FR 58755 
through 58759), based on our analysis of the impact on resource use for 
the ICD-10-CM Z codes that describe homelessness and after 
consideration of public comments, we finalized changes to the severity 
levels for diagnosis codes Z59.00 (Homelessness, unspecified), Z59.01 
(Sheltered homelessness), and Z59.02 (Unsheltered homelessness), from 
NonCC to CC. We stated our expectation that finalizing the changes 
would encourage the increased documentation and reporting of the 
diagnosis codes describing social and economic circumstances and serve 
as an example for providers that, when they document and report SDOH 
codes, CMS can further examine the claims data and consider future 
changes to the designation of these codes when reported as a secondary 
diagnosis. We further stated CMS would continue to monitor and evaluate 
the reporting of the diagnosis codes describing social and economic 
circumstances.
    We refer the reader to the following section of this proposed rule 
for our proposed changes to the severity level designation for the 
diagnosis codes that describe inadequate housing and housing 
instability for FY 2025.
    We have updated the Impact on Resource Use Files on the CMS website 
so that the public can review the mathematical data for the impact on 
resource use generated using claims from the FY 2019 through the FY 
2023 MedPAR files. These files are posted on the CMS website at https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps/ms-drg-classifications-and-software. As discussed in 
prior rulemaking, we also continue to be interested in receiving 
feedback on how we might further foster the documentation and reporting 
of the

[[Page 35997]]

most specific diagnosis codes supported by the available medical record 
documentation and clinical knowledge of the patient's health condition 
to more accurately reflect each health care encounter and improve the 
reliability and validity of the coded data.
    For new diagnosis codes approved for FY 2025, consistent with our 
annual process for designating a severity level (MCC, CC, or NonCC) for 
new diagnosis codes, we first review the predecessor code designation, 
followed by review and consideration of other factors that may be 
relevant to the severity level designation, including the severity of 
illness, treatment difficulty, complexity of service and the resources 
utilized in the diagnosis or treatment of the condition. We note that 
this process does not automatically result in the new diagnosis code 
having the same designation as the predecessor code. We refer the 
reader to section II.C.13 of this proposed rule for the discussion of 
the proposed changes to the ICD-10-CM and ICD-10-PCS coding systems for 
FY 2025.
c. Proposed Changes to Severity Levels
1. SDOH--Inadequate Housing/Housing Instability
    As discussed earlier in this section, in continuation of our 
examination of the SDOH Z codes, for this proposed rule, we reviewed 
the mathematical data on the impact on resource use for the subset of 
ICD-10-CM Z codes that describe the social determinants of health found 
in categories Z55-Z65 (Persons with potential health hazards related to 
socioeconomic and psychosocial circumstances).
    The ICD-10-CM SDOH Z codes that describe inadequate housing and 
housing instability are currently designated as NonCCs when reported as 
secondary diagnoses. The following table reflects the impact on 
resource use data generated using claims from the September 2023 update 
of the FY 2023 MedPAR file. We refer readers to the FY 2008 IPPS/LTCH 
PPS final rule (72 FR 47159) for a complete discussion of our 
historical approach to mathematically evaluate the extent to which the 
presence of an ICD-10-CM code as a secondary diagnosis resulted in 
increased hospital resource use, and a more detailed explanation of the 
columns in the table.
[GRAPHIC] [TIFF OMITTED] TP02MY24.060

    The table shows that the C1 value is 2.63 for ICD-10-CM diagnosis 
code Z59.10 and 1.85 for ICD-10-CM diagnosis code Z59.19. A value close 
to 2.0 in column C1 suggests that the secondary diagnosis is more 
aligned with a CC than a NonCC. Because the C1 values in the table are 
generally close to 2, the data suggest that when these two SDOH Z codes 
are reported as a secondary diagnosis, the resources involved in caring 
for a patient experiencing inadequate housing support increasing the 
severity level from a NonCC to a CC. In contrast, the C1 value for ICD-
10-CM diagnosis code Z59.11 is 0.51 and is 0.99 for ICD-10-CM diagnosis 
code Z59.12. A C1 value generally closer to 1 suggests the resources 
involved in caring for patients experiencing inadequate housing in 
terms of environmental temperature and utilities are more aligned with 
a NonCC severity level than a CC or an MCC severity level.
    The underlying cause of the inconsistency between the C1 values for 
inadequate housing, unspecified and other inadequate housing and the 
two more specific codes that describe the necessities unavailable in 
the housing environment is unclear. We note that diagnosis codes Z59.10 
(Inadequate housing, unspecified), Z59.11 (Inadequate housing 
environmental temperature), Z59.12 (Inadequate housing utilities), and 
Z59.19 (Other inadequate housing) became effective on April 1, 2023 (FY 
2023). In reviewing the historical C1 values for code Z59.1 (Inadequate 
housing), the predecessor code before the code was expanded to further 
describe inadequate housing and the basic necessities unavailable in 
the housing environment, we note the mathematical data for the impact 
on resource use generated using claims from the FY 2019, FY 2020, FY 
2021, and FY 2022 MedPAR files reflects C1 values for code Z59.1 of 
2.09, 1.73, 2.04, and 2.69, respectively. We refer the reader to the 
Impact on Resource Use Files generated using claims from the FY 2019 
through the FY 2022 MedPAR files posted on the CMS website at https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps/ms-drg-classifications-and-software. We believe the lower 
C1 values for ICD-10-CM

[[Page 35998]]

codes Z59.11 (Inadequate housing environmental temperature) and Z59.12 
(Inadequate housing utilities) reflected in the mathematical data for 
the impact on resource use generated using claims from the FY 2023 
MedPAR file may be attributed to lack of use or knowledge about the 
newly expanded codes, such that the data may not yet reflect the full 
impact on resource use for patients experiencing these circumstances.
    Similarly, the table shows that the C1 value is 1.97 for ICD-10-CM 
diagnosis code Z59.811. A value close to 2.0 in column C1 suggests that 
the secondary diagnosis is more aligned with a CC than a NonCC. Because 
the C1 value in the table is generally close to 2, the data suggest 
that when this SDOH Z code is reported as a secondary diagnosis, the 
resources involved in caring for a patient experiencing an imminent 
risk of homelessness support increasing the severity level from a NonCC 
to a CC. In contrast, the C1 value for ICD-10-CM diagnosis code Z59.812 
(Housing instability, housed, homelessness in past 12 months) and 
(Housing instability, housed unspecified) is 0.76 and is 0.92 for ICD-
10-CM diagnosis code Z59.819. A C1 value generally closer to 1 suggests 
the resources involved in caring for patients experiencing housing 
instability, with history of homelessness in the past 12 months or 
housing instability, unspecified are more aligned with a NonCC severity 
level than a CC or an MCC severity level. The underlying cause of the 
inconsistency between the C1 values for codes describing housing 
instability is unclear.
    We note that diagnosis codes Z59.811, Z59.812, and Z59.819 became 
effective on October 1, 2021 (FY 2022). In reviewing the historical C1 
values for code Z59.8 (Other problems related to housing and economic 
circumstances), the predecessor code before the code was expanded to 
further describe the problems related to housing and economic 
circumstances, we note the mathematical data for the impact on resource 
use generated using claims from the FY 2019 and FY 2020 MedPAR files 
reflects C1 values for code Z59.8 of 1.92 and 1.63, respectively. There 
were no data reflected for this code in the Impact on Resource Use File 
generated using claims from the FY 2021 MedPAR files. The mathematical 
data for the impact on resource use generated using claims from the FY 
2022 MedPAR file reflects C1 values for codes Z59.811, Z59.812, and 
Z59.819 of 2.44, 3.12, and 2.09, respectively. We are uncertain if the 
fluctuations in the C1 values from year to year, or FY 2021, in 
particular, may reflect fluctuations that may be a result of the COVID-
19 public health emergency or even reduced hospitalizations of certain 
conditions. We are also uncertain if the fluctuations may be attributed 
to lack of use or knowledge about the expanded codes, such that the 
data on the reporting of codes Z59.812 and Z59.819 may not yet reflect 
the full impact on resource use for patients experiencing these 
circumstances.
    As discussed in the FY 2021 IPPS/LTCH PPS final rule (85 FR 58550 
through 58554), following the listening session on October 8, 2019, we 
reconvened an internal workgroup comprised of clinicians, consultants, 
coding specialists and other policy analysts to identify guiding 
principles to apply in evaluating whether changes to the severity level 
designations of diagnoses are needed and to ensure the severity 
designations appropriately reflect resource use based on review of the 
claims data, as well as consideration of relevant clinical factors (for 
example, the clinical nature of each of the secondary diagnoses and the 
severity level of clinically similar diagnoses) and improve the overall 
accuracy of the IPPS payments.
    In considering the nine guiding principles identified by the 
workgroup, as summarized previously, we note that, similar to 
homelessness, inadequate housing and housing instability are 
circumstances that can impede patient cooperation or management of 
care, or both. In addition, patients experiencing inadequate housing 
and housing instability can require a higher level of care by needing 
an extended length of stay.
    Inadequate housing is defined as an occupied housing unit that has 
moderate or severe physical problems (for example, deficiencies in 
plumbing, heating, electricity, hallways, and upkeep).6 7 
Features of substandard housing have long been identified as 
contributing to the spread of infectious diseases. Patients living in 
inadequate housing may be exposed to health and safety risks, such as 
vermin, mold, water leaks, and inadequate heating or cooling 
systems.8 9 An increasing body of evidence has associated 
poor housing conditions with morbidity from infectious diseases, 
chronic illnesses, exposure to toxins, injuries, poor nutrition, and 
mental disorders.\10\

    Housing instability encompasses a number of challenges, such as 
having trouble paying rent, overcrowding, moving frequently, or 
spending the bulk of household income on housing.\11\ These experiences 
may negatively affect physical health and make it harder to access 
health care. Studies have found moderate evidence to suggest that 
housing instability is associated with higher prevalence of overweight/
obesity, hypertension, diabetes, and cardiovascular disease, worse 
hypertension and diabetes control, and higher acute health care 
utilization among those with diabetes and cardiovascular disease.\12\

    In reviewing the mathematical data for the impact on resource use 
generated using claims from the FY 2023 MedPAR file for the seven ICD-
10-CM codes describing inadequate housing and housing instability 
comprehensively and reviewing the potential impact these circumstances 
could have on patients' clinical course, we note that whether the 
patient is experiencing inadequate housing or housing instability, the 
patient may have limited or no access to prescription medicines or 
over-the-counter medicines, including adequate locations to store 
medications away from the heat or cold, and have difficulties adhering 
to medication regimens. Experiencing inadequate housing or housing 
instability may negatively affect a patient's physical health and make 
it harder to access timely health care.\8,9\ Delays in medical care may 
increase morbidity and mortality risk among those with underlying, 
preventable, and treatable medical conditions.\13\ In

addition, findings also suggest that patients experiencing inadequate 
housing or housing instability are associated with higher rates of 
inpatient admissions for mental, behavioral, and neurodevelopmental 
disorders, longer hospital stays, and substantial health care 
costs.\14\

---------------------------------------------------------------------------

    Therefore, after considering the impact on resource use data 
generated using claims from the September 2023 update of the FY 2023 
MedPAR file for the seven ICD-10-CM diagnosis codes that describe 
inadequate housing and housing instability and consideration of the 
nine guiding principles, we are proposing to change the severity level 
designation for diagnosis codes Z59.10 (Inadequate housing, 
unspecified), Z59.11 (Inadequate housing environmental temperature), 
Z59.12 (Inadequate housing utilities), Z59.19 (Other inadequate 
housing), Z59.811 (Housing instability, housed, with risk of 
homelessness), Z59.812 (Housing instability, housed, homelessness in 
past 12 months) and Z59.819 (Housing instability, housed unspecified) 
from NonCC to CC for FY 2025.
    As discussed in the FY 2023 IPPS/LTCH PPS final rule (87 FR 48868), 
if SDOH Z codes are not consistently reported in inpatient claims data, 
our methodology utilized to mathematically measure the impact on 
resource use, as described previously, may not adequately reflect what 
additional resources were expended by the hospital to address these 
SDOH circumstances in terms of requiring clinical evaluation, extended 
length of hospital stay, increased nursing care or monitoring or both, 
and comprehensive discharge planning. We will continue to monitor SDOH 
Z code reporting, including reporting based on SDOH screening performed 
as a result of new quality measures in the Hospital Inpatient Quality 
Reporting program. We may consider proposing changes for other SDOH 
codes in the future based on our analysis of the impact on resource 
use, per our methodology, as previously described, and consideration of 
the guiding principles. We also continue to be interested in receiving 
feedback on how we might otherwise foster the documentation and 
reporting of the diagnosis codes describing social and economic 
circumstances to more accurately reflect each health care encounter and 
improve the reliability and validity of the coded data including in 
support of efforts to advance health equity.
    To inform future rulemaking, feedback and other suggestions may be 
submitted by October 20, 2024 and directed to MEARISTM at: 
https://mearis.cms.gov/public/home.
2. Causally Specified Delirium
    Additionally, for this FY 2025 IPPS/LTCH PPS proposed rule, we 
received a request to change the severity level designations of the 
ICD-10-CM diagnosis codes that describe causally specified delirium 
from CC to MCC when reported as secondary diagnoses. Causally specified 
delirium is delirium caused by the physiological effects of a medical 
condition, by the direct physiological effects of a substance or 
medication, including withdrawal, or by multiple or unknown etiological 
factors. The requestor noted that ICD-10-CM diagnosis codes G92.8 
(Other toxic encephalopathy), G92.9 (Unspecified toxic encephalopathy) 
and G93.41 (Metabolic encephalopathy) are currently all designated as 
MCCs. According to the requestor, a diagnosis of delirium implies an 
underlying acute encephalopathy, and as such, the severity designation 
of the diagnosis codes that describe causally specified delirium should 
be on par with the severity designation of the diagnosis codes that 
describe toxic encephalopathy and metabolic encephalopathy. The 
requestor stated that toxic encephalopathy, metabolic encephalopathy, 
and causally specified delirium all describe core symptoms of 
impairment of level of consciousness and cognitive change caused by a 
medical condition or substance.
    The requestor further stated that there is robust literature 
detailing the impact delirium can have on cognitive decline, rates of 
functional decline, subsequent dementia diagnosis, 
institutionalization, care complexity and costs, readmission rates, and 
mortality. The requestor considered each of the nine guiding principles 
discussed earlier in this section and noted how each of the principles 
could be applied in evaluating changes to the severity designations of 
the diagnosis codes that describe causally specified delirium in their 
request. Specifically, the requestor stated that delirium is a textbook 
example that maps to the nine guiding principles for evaluating a 
potential change in severity designation in that delirium (1) has a 
bidirectional link with dementia, (2) indexes physiological 
vulnerability across populations, (3) impacts healthcare systems across 
levels of care, (4) complicates postoperative recovery, (5) consigns 
patients to higher levels of care, and for longer, (6)impedes patient 
engagement in care, (7) has several recent treatment guidelines, (8) 
indicates neuronal/brain injury, and (9) represents a common expression 
of terminal illness.
    The requestor identified 37 ICD-10-CM diagnosis codes that describe 
causally specified delirium. We agree that these 37 diagnosis codes are 
all currently designated as CCs. We refer the reader to Appendix G of 
the ICD-10 MS-DRG Version 41.1 Definitions Manual (available on the CMS 
website at: https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps/ms-drg-classifications-and-software) for 
the complete list of diagnoses designated as CCs when reported as 
secondary diagnoses, except when used in conjunction with the principal 
diagnosis in the corresponding CC Exclusion List in Appendix C. To 
evaluate this request, we analyzed the claims data in the September 
2023 update of the FY 2023 MedPAR file. The following table shows the 
analysis for each of the diagnosis codes identified by the requestor 
that describe causally specified delirium.
BILLING CODE 4120-01-P

[[Page 36000]]

[GRAPHIC] [TIFF OMITTED] TP02MY24.061


[[Page 36001]]


[GRAPHIC] [TIFF OMITTED] TP02MY24.062

BILLING CODE 4120-01-C
    We analyzed these data as described in FY 2008 IPPS final rule (72 
FR 47158 through 47161). The table shows that the C1 values of the 
diagnosis codes that describe causally specified delirium range from a 
low of 0.35 to a high of 4.00. As stated earlier, a C1 value close to 
2.0 suggests the condition is more like a CC than a non-CC but not as 
significant in resource usage as an MCC. On average, the C1 values of 
the diagnoses that describe causally specified delirium suggest that 
these codes are more like a NonCC than a CC. We note diagnosis code 
F11.221 (Opioid dependence with intoxication delirium) had a C1 value 
of 4.00, however our analysis reflects that this diagnosis code was 
reported as a secondary diagnosis in only 42 claims, and only one claim 
reported F11.221 as a secondary diagnosis with no other secondary 
diagnosis or with all other secondary diagnoses that are NonCCs.
    The C2 findings of the diagnosis codes that describe causally 
specified delirium range from a low of 0.28 to a high of 3.22 and the 
C3 findings range from a low of 1.25 to a high of 3.85. The data are 
clearly mixed between the C2 and C3 findings, and do not consistently 
support a change in the severity level. On average, the C2 and C3 
findings again suggest that these codes that describe causally 
specified delirium are more similar to a NonCC.
    In considering the nine guiding principles, as summarized 
previously, we note that delirium is a diagnosis that can impede 
patient cooperation or management of care or both. Delirium is a 
confusional state that can manifest as agitation, tremulousness, and 
hallucinations or even somnolence and decreased arousal. In addition, 
patients diagnosed with delirium can require a higher level of care by 
needing intensive monitoring, and a greater number of caregivers. 
Managing disruptive behavior, particularly agitation and combative 
behavior, is a challenging aspect in caring for patients diagnosed with 
delirium. Prevention and treatment of delirium can include avoiding 
factors known to cause or aggravate delirium; identifying and treating 
the underlying acute illness; and where appropriate using low-dose, 
short-acting pharmacologic agents.
    After considering the C1, C2, and C3 values of the 37 ICD-10-CM 
diagnosis codes that describe causally specified delirium and 
consideration of the nine guiding principles, we believe these 37 codes 
should not be designated as MCCs. While there is a lack of consistent 
claims data to support a severity level change from CCs to MCCs, we 
recognize patients with delirium can utilize increased hospital 
resources and can be at a higher severity level. Therefore, we are 
proposing to retain the severity designation of the 37 codes listed 
previously as CCs for FY 2025.
d. Proposed Additions and Deletions to the Diagnosis Code Severity 
Levels for FY 2025
    The following tables identify the proposed additions and deletions 
to the diagnosis code MCC severity levels list and the proposed 
additions and deletions to the diagnosis code CC severity levels list

e. Proposed CC Exclusions List for FY 2025
    In the September 1, 1987 final notice (52 FR 33143) concerning 
changes to the DRG classification system, we modified the GROUPER logic 
so that certain diagnoses included on the standard list of CCs would 
not be considered valid CCs in combination with a particular principal 
diagnosis. We created the CC Exclusions List for the following reasons: 
(1) to preclude coding of CCs for closely related conditions; (2) to 
preclude duplicative or inconsistent coding from being treated as CCs; 
and (3) to ensure that cases are appropriately classified between the 
complicated and uncomplicated DRGs in a pair.
    In the May 19, 1987 proposed notice (52 FR 18877) and the September 
1, 1987 final notice (52 FR 33154), we explained that the excluded 
secondary diagnoses were established using the following five 
principles:
     Chronic and acute manifestations of the same condition 
should not be considered CCs for one another;
     Specific and nonspecific (that is, not otherwise specified 
(NOS)) diagnosis codes for the same condition should not be considered 
CCs for one another;
     Codes for the same condition that cannot coexist, such as 
partial/total, unilateral/bilateral, obstructed/unobstructed, and 
benign/malignant, should not be considered CCs for one another;
     Codes for the same condition in anatomically proximal 
sites should not be considered CCs for one another; and
     Closely related conditions should not be considered CCs 
for one another.
    The creation of the CC Exclusions List was a major project 
involving hundreds of codes. We have continued to review the remaining 
CCs to identify additional exclusions and to remove diagnoses from the 
master list that have been shown not to meet the definition of a CC. We 
refer readers to the FY 2014 IPPS/LTCH PPS final rule (78 FR 50541 
through 50544) for detailed information regarding revisions that were 
made to the CC and CC Exclusion Lists under the ICD-9-CM MS-DRGs.
    The ICD-10 MS-DRGs Version 41.1 CC Exclusion List is included as 
Appendix C in the ICD-10 MS-DRG Definitions Manual (available on the 
CMS website at: https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/index.html) and includes two lists identified 
as Part 1 and Part 2. Part 1 is the list of all diagnosis codes that 
are defined as a CC or MCC when reported as a secondary diagnosis. For 
all diagnosis codes on the list, a link is provided to a collection of 
diagnosis codes which, when reported as the principal diagnosis, would 
cause the CC or MCC diagnosis to be considered as a NonCC. Part 2 is 
the list of diagnosis codes designated as an MCC only for patients 
discharged alive; otherwise, they are assigned as a NonCC.
    Effective for the April 1, 2024 release of the ICD-10 MS-DRG 
Definitions Manual, Version 41.1, a new section has been added to 
Appendix C as follows:
Part 3: Secondary Diagnosis CC/MCC Severity Exclusions in Select MS-
DRGs
    Part 3 lists diagnosis codes that are designated as a complication 
or comorbidity (CC) or major complication or comorbidity (MCC) and 
included in the definition of the logic for the listed MS-DRGs. When 
reported as a secondary diagnosis and grouped to one of the listed MS-
DRGs, the diagnosis is excluded from acting as a CC/MCC for severity in 
DRG assignment.
    The purpose of this new section is to include the list of MS-DRGs 
subject to what is referred to as suppression logic. In addition to the 
suppression logic excluding secondary diagnosis CC or MCC conditions 
that may be included in the definition of the logic for a DRG, it is 
also based on the presence of other secondary diagnosis logic defined 
within certain base DRGs. Therefore, if a MS-DRG has secondary 
diagnosis logic, the suppression is activated regardless of the 
severity of the secondary diagnosis code(s) for appropriate grouping 
and MS-DRG assignment.
    Each MS-DRG is defined by a particular set of patient attributes 
including principal diagnosis, specific secondary diagnoses, 
procedures, sex, and discharge status. The patient attributes which 
define each MS-DRG are displayed in a series of headings which indicate 
the patient characteristics used to define the MS-DRG. These headings 
indicate how the patient's diagnoses and procedures are used in 
determining MS-DRG assignment. Following each heading is a complete 
list of all the ICD-10-CM diagnosis or ICD-10-PCS procedure codes 
included in the MS-DRG. One of these headings is secondary diagnosis.
     Secondary diagnosis. Indicates that a specific set of 
secondary diagnoses are used in the definition of the MS-DRG. For 
example, a secondary diagnosis of acute leukemia with chemotherapy is 
used to define MS-DRG 839.
    The full list of MS-DRGs where suppression occurs is shown in the 
following table.

[[Page 36003]]

[GRAPHIC] [TIFF OMITTED] TP02MY24.063

    We believe this additional information about the suppression logic 
may further assist users of the ICD-10 MS-DRG GROUPER software and 
related materials.
    In our review of the MS-DRGs containing secondary diagnosis logic 
in association with the suppression logic previously discussed, we 
identified another set of MS-DRGs containing secondary diagnosis logic 
in the definition of the MS-DRG. Specifically, we identified MS-DRGs 
673, 674, and 675 (Other Kidney and Urinary Tract Procedures with MCC, 
with CC, and without CC/MCC, respectively) in MDC 11 (Diseases and 
Disorders of the Kidney and Urinary Tract), as displayed in the ICD-10 
MS-DRG Version 41.1 Definitions Manual (which is available on the CMS 
website at: https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps/ms-drg-classifications-and-software) which 
contains secondary diagnosis logic.
    Of the seven logic lists included in the definition of MS-DRGs 673, 
674, and 675, there are three ``Or Principal Diagnosis'' logic lists 
and one ``With Secondary Diagnosis'' logic list. The first ``Or 
Principal Diagnosis'' logic list is comprised of 21 diagnosis codes 
describing conditions such as chronic kidney disease, kidney failure, 
and complications related to a vascular dialysis catheter or kidney 
transplant. The second ``Or Principal Diagnosis'' logic list is 
comprised of four diagnosis codes describing diabetes with diabetic 
chronic kidney disease followed by a ``With Secondary Diagnosis'' logic 
list that includes diagnosis codes N18.5 (Chronic kidney disease, stage 
5) and N18.6 (End stage renal disease). These logic lists are 
components of the special logic in MS-DRGs 673, 674, and 675 for 
certain MDC 11 diagnoses reported with procedure codes for the 
insertion of tunneled or totally implantable vascular access devices. 
The third ``Or Principal Diagnosis'' logic list is comprised of three 
diagnosis codes describing Type 1 diabetes with different kidney 
complications as part of the special logic in MS-DRGs 673, 674, and 675 
for pancreatic islet cell transplantation performed in the absence of 
any other surgical procedure.
    Under the Version 41.1 ICD-10 MS-DRGs, diagnosis code N18.5 
(Chronic kidney disease, stage 5) is currently designated as a CC and 
diagnosis code N18.6 (End stage renal disease) is designated as an MCC. 
In our review of the MS-DRGs containing secondary diagnosis logic in 
association with the suppression logic, we noted that currently, when 
some diagnosis codes from the ``Or Principal Diagnosis'' logic lists in 
MS-DRGs 673, 674, and 675 are reported as the principal diagnosis and 
either diagnosis code N18.5 or N18.6 from the ``With Secondary 
Diagnosis'' logic list is reported as a secondary diagnosis, some cases 
are grouping to MS-DRG 673 (Other Kidney and Urinary Tract Procedures 
with MCC) or to MS-DRG 674 (Other Kidney and Urinary Tract Procedures 
with CC) in the absence of any other MCC or CC secondary diagnoses 
being reported.
    In our analysis of this issue, we noted that diagnosis codes N18.5 
and N18.6 are excluded from acting as a CC or MCC, when reported with 
principal

[[Page 36004]]

diagnoses from Principal Diagnosis Collection Lists 1379 and 1380, 
respectively, as reflected in Part 1 of Appendix C in the CC Exclusion 
List. We refer the reader to Part 1 of Appendix C in the CC Exclusion 
List as displayed in the ICD-10 MS-DRG Version 41.1 Definitions Manual 
(which is available on the CMS website at: https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps/ms-drg-classifications-and-software) for the complete list of principal 
diagnoses in Principal Diagnosis Collection Lists 1379 and 1380. 
Specifically, when codes N18.5 or N18.6 are reported as secondary 
diagnoses, they are considered as NonCCs when the diagnosis codes from 
the ``Or Principal Diagnosis'' logic lists in MS-DRGs 673, 674, and 675 
reflected in the following table are reported as the principal 
diagnosis under the CC Exclusion logic.
[GRAPHIC] [TIFF OMITTED] TP02MY24.064

    We also noted that currently, a subset of diagnosis codes from the 
first ``Or Principal Diagnosis'' logic list in MS-DRGs 673, 674, and 
675 are not listed in Principal Diagnosis Collection Lists 1379 or 1380 
for diagnosis codes N18.5 and N18.6, respectively. As a result, when 
one of the 13 diagnosis codes listed in the following table are 
reported as the principal diagnosis, and either diagnosis code N18.5 or 
N18.6 from the ``With Secondary Diagnosis'' logic list are reported as 
a secondary diagnosis, the cases are grouping to MS-DRG 673 (Other 
Kidney and Urinary Tract Procedures with MCC) or to MS-DRG 674 (Other 
Kidney and Urinary Tract Procedures with CC) when also reported with a 
procedure code describing the insertion of a tunneled or totally 
implantable vascular access device.

[[Page 36005]]

[GRAPHIC] [TIFF OMITTED] TP02MY24.065

    Consistent with how other similar logic lists function in the ICD-
10 GROUPER software for case assignment to the ``with MCC'' or ``with 
CC'' MS-DRGs, the logic for case assignment to MS-DRG 673 is intended 
to require any other diagnosis designated as an MCC and reported as a 
secondary diagnosis for appropriate assignment, and not the diagnoses 
currently listed in the logic for the definition of the MS-DRG. 
Likewise, the logic for case assignment to MS-DRG 674 is intended to 
require any other diagnosis designated as a CC and reported as a 
secondary diagnosis for appropriate assignment.
    Therefore, for FY 2025, we are proposing to correct the logic for 
case assignment to MS-DRGs 673, 674, and 675 by adding suppression 
logic to exclude diagnosis codes N18.5 (Chronic kidney disease, stage 
5) and N18.6 (End stage renal disease) from the logic list entitled 
``With Secondary Diagnosis'' from acting as a CC or an MCC, 
respectively, when reported as a secondary diagnosis with one of the 13 
previously listed principal diagnosis codes from the ``Or Principal 
Diagnosis'' logic lists in MS-DRGs 673, 674, and 675 for appropriate 
grouping and MS-DRG assignment. Under this proposal, when diagnosis 
codes N18.5 or N18.6 are reported as a secondary diagnosis with one of 
the 13 previously listed principal diagnosis codes, the GROUPER will 
assign MS-DRG 675 (Other Kidney and Urinary Tract Procedures without 
CC/MCC) in the absence of any other MCC or CC secondary diagnoses being 
reported. We also note that the current list of MS-DRGs subject to 
suppression logic as previously discussed and listed under Version 41.1 
includes MS-DRGs that are not subdivided by a two-way severity level 
split (``with MCC and without MCC'' or ``with CC/MCC and without CC/
MCC'') or a three-way severity level split (with MCC, with CC, and 
without CC/MCC, respectively), or the listed MS-DRG includes diagnoses 
that are not currently designated as a CC or MCC. To avoid potential 
confusion, we are proposing to refine how the suppression logic is 
displayed under Appendix C--Part 3 to not display the MS-DRGs where the 
suppression logic has no impact on the grouping (meaning the logic list 
for the affected MS-DRG contains diagnoses that are all designated as 
NonCCs, or the MS-DRG is not subdivided by a severity level split) as 
reflected in the draft Version 42 ICD-10 MS-DRG Definitions Manual, 
which is available in association with this proposed rule at: https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps.
    In addition, we are proposing changes to the ICD-10 MS-DRGs Version 
42 CC Exclusion List based on the diagnosis code updates as discussed 
in section II.C.13. of this FY 2025 IPPS/LTCH PPS proposed rule. 
Therefore, we have developed Table 6G.1.--Proposed Secondary Diagnosis 
Order Additions to the CC Exclusions List--FY 2025; Table 6G.2.--
Proposed Principal Diagnosis Order Additions to the CC Exclusions 
List--FY 2025; Table 6H.1.--Proposed Secondary Diagnosis Order 
Deletions to the CC Exclusions List--FY 2025; and Table 6H.2.--Proposed 
Principal Diagnosis Order Deletions to the CC Exclusions List--FY 2025. 
For Table 6G.1, each secondary diagnosis code proposed for addition to 
the CC Exclusion List is shown with an asterisk and the principal 
diagnoses proposed to exclude the secondary diagnosis code are provided 
in the indented column immediately following it. For Table 6G.2, each 
of the principal diagnosis codes for which there is a CC exclusion is 
shown with an asterisk and the conditions proposed for addition to the 
CC Exclusion List that will not count as a CC are provided in an 
indented column immediately following the affected principal diagnosis. 
For Table 6H.1, each secondary diagnosis code proposed for deletion 
from the CC Exclusion List is shown with an asterisk followed by the 
principal diagnosis codes that currently exclude it. For Table 6H.2, 
each of the principal diagnosis codes is shown with an asterisk and the 
proposed deletions to the CC Exclusions List are provided in an 
indented column immediately following the affected principal

[[Page 36006]]

diagnosis. Tables 6G.1., 6G.2., 6H.1., and 6H.2. associated with this 
proposed rule are available on the CMS website at: https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/index.html.
13. Proposed Changes to the ICD-10-CM and ICD-10-PCS Coding Systems
    To identify new, revised and deleted diagnosis and procedure codes, 
for FY 2025, we have developed Table 6A.--New Diagnosis Codes, Table 
6B.--New Procedure Codes, Table 6C.--Invalid Diagnosis Codes, Table 
6D.--Invalid Procedure Codes, Table 6E.--Revised Diagnosis Code Titles, 
and Table 6F.--Revised Procedure Code Titles for this proposed rule. 
These tables are not published in the Addendum to this proposed rule, 
but are available on the CMS website at: https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/index.html as 
described in section VI. of the Addendum to this proposed rule. As 
discussed in section II.C.15. of the preamble of this proposed rule, 
the code titles are adopted as part of the ICD-10 (previously ICD-9-CM) 
Coordination and Maintenance Committee meeting process. Therefore, 
although we publish the code titles in the IPPS proposed and final 
rules, they are not subject to comment in the proposed or final rules.
    We are proposing the MDC and MS-DRG assignments for the new 
diagnosis codes and procedure codes as set forth in Table 6A.--New 
Diagnosis Codes and Table 6B.--New Procedure Codes. In addition, the 
proposed severity level designations for the new diagnosis codes are 
set forth in Table 6A. and the proposed O.R. status for the new 
procedure codes are set forth in Table 6B. Consistent with our 
established process, we examined the MS-DRG assignment and the 
attributes (severity level and O.R. status) of the predecessor 
diagnosis or procedure code, as applicable, to inform our proposed 
assignments and designations. Specifically, we review the predecessor 
code and MS-DRG assignment most closely associated with the new 
diagnosis or procedure code, and in the absence of claims data, we 
consider other factors that may be relevant to the MS-DRG assignment, 
including the severity of illness, treatment difficulty, complexity of 
service and the resources utilized in the diagnosis and/or treatment of 
the condition. We note that this process does not automatically result 
in the new diagnosis or procedure code being proposed for assignment to 
the same MS-DRG or to have the same designation as the predecessor 
code.

14. Proposed Changes to the Surgical Hierarchies
    Some inpatient stays entail multiple surgical procedures, each one 
of which, occurring by itself, could result in assignment of the case 
to a different MS-DRG within the MDC to which the principal diagnosis 
is assigned. Therefore, it is necessary to have a decision rule within 
the GROUPER by which these cases are assigned to a single MS-DRG. The 
surgical hierarchy, an ordering of surgical classes from most resource-
intensive to least resource-intensive, performs that function. 
Application of this hierarchy ensures that cases involving multiple 
surgical procedures are assigned to the MS-DRG associated with the most 
resource-intensive surgical class.
    A surgical class can be composed of one or more MS-DRGs. For 
example, in MDC 11, the surgical class ``kidney transplant'' consists 
of a single MS-DRG (MS-DRG 652) and the class ``major bladder 
procedures'' consists of three MS-DRGs (MS-DRGs 653, 654, and 655).
    Consequently, in many cases, the surgical hierarchy has an impact 
on more than one MS-DRG. The methodology for determining the most 
resource-intensive surgical class involves weighting the average 
resources for each MS-DRG by frequency to determine the weighted 
average resources for each surgical class. For example, assume surgical 
class A includes MS-DRGs 001 and 002 and surgical class B includes MS-
DRGs 003, 004, and 005. Assume also that the average costs of MS-DRG 
001 are higher than that of MS-DRG 003, but the average costs of MS-
DRGs 004 and 005 are higher than the average costs of MS-DRG 002. To 
determine whether surgical class A should be higher or lower than 
surgical class B in the surgical hierarchy, we would weigh the average 
costs of each MS-DRG in the class by frequency (that is, by the number 
of cases in the MS-DRG) to determine average resource consumption for 
the surgical class. The surgical classes would then be ordered from the 
class with the highest average resource utilization to that with the 
lowest, with the exception of ``other O.R. procedures'' as discussed in 
this proposed rule.
    This methodology may occasionally result in assignment of a case 
involving multiple procedures to the lower-weighted MS-DRG (in the 
highest, most resource-intensive surgical class) of the available 
alternatives. However, given that the logic underlying the surgical 
hierarchy provides that the GROUPER search for the procedure in the 
most resource-intensive surgical class, in cases involving multiple 
procedures, this result is sometimes unavoidable.
    We note that, notwithstanding the foregoing discussion, there are a 
few instances when a surgical class with a lower average cost is 
ordered above a surgical class with a higher average cost. For example, 
the ``other O.R. procedures'' surgical class is uniformly ordered last 
in the surgical hierarchy of each MDC in which it occurs, regardless of 
the fact that the average costs for the MS-DRG or MS-DRGs in that 
surgical class may be higher than those for other surgical classes in 
the MDC. The ``other O.R. procedures'' class is a group of procedures 
that are only infrequently related to the diagnoses in the MDC but are 
still occasionally performed on patients with cases assigned to the MDC 
with these diagnoses. Therefore, assignment to these surgical classes 
should only occur if no other surgical class more closely related to 
the diagnoses in the MDC is appropriate.
    A second example occurs when the difference between the average 
costs for two surgical classes is very small. We have found that small 
differences generally do not warrant reordering of the hierarchy 
because, as a result of

[[Page 36007]]

reassigning cases on the basis of the hierarchy change, the average 
costs are likely to shift such that the higher-ordered surgical class 
has lower average costs than the class ordered below it.
    Based on the changes that we are proposing to make for FY 2025, as 
discussed in section II.C. of the preamble of this proposed rule, we 
are proposing to modify the existing surgical hierarchy for FY 2025 as 
follows.
    As discussed in section II.C.4.a. of the preamble of this proposed 
rule, we are proposing to revise the surgical hierarchy for the MDC 05 
(Diseases and Disorders of the Circulatory System) MS-DRGs as follows: 
In the MDC 05 MS-DRGs, we are proposing to sequence proposed new MS-DRG 
317 (Concomitant Left Atrial Appendage Closure and Cardiac Ablation) 
above MS-DRG 275 (Cardiac Defibrillator Implant with Cardiac 
Catheterization and MCC) and below MS-DRGs 231, 232, 233, 234, 235, and 
236 (Coronary Bypass with or without PTCA, with or without Cardiac 
Catheterization or Open Ablation, with and without MCC, respectively). 
As discussed in section II.C.4.b. of the preamble of this proposed 
rule, we are proposing to revise the title for MS-DRG 276 from 
``Cardiac Defibrillator Implant with MCC'' to ``Cardiac Defibrillator 
Implant with MCC or Carotid Sinus Neurostimulator''.
    As discussed in section II.C.6.b. of the preamble of this proposed 
rule, we are proposing to delete MS-DRGs 453, 454, and 455 (Combined 
Anterior and Posterior Spinal Fusion with MCC, with CC, and without CC/
MCC, respectively). Based on the changes we are proposing to make for 
those MS-DRGs in MDC 08 (Diseases and Disorders of the Musculoskeletal 
System and Connective Tissue), we are proposing to revise the surgical 
hierarchy for MDC 08 as follows: In MDC 08, we are proposing to 
sequence proposed new MS-DRGs 426, 427, and 428 (Multiple Level 
Combined Anterior and Posterior Spinal Fusion Except Cervical with MCC, 
with CC, and without CC/MCC, respectively) above proposed new MS-DRG 
402 (Single Level Combined Anterior and Posterior Spinal Fusion Except 
Cervical). We are proposing to sequence proposed new MS-DRGs 429 and 
430 (Combined Anterior and Posterior Cervical Spinal Fusion with MCC 
and without MCC, respectively) above MS-DRGs 456, 457, and 458 (Spinal 
Fusion Except Cervical with Spinal Curvature, Malignancy, Infection or 
Extensive Fusions with MCC, with CC, and without CC/MCC, respectively) 
and below proposed new MS-DRG 402. We are proposing to sequence 
proposed new MS-DRGs 447 and 448 (Multiple Level Spinal Fusion Except 
Cervical with MCC and without MCC, respectively) above proposed revised 
MS-DRGs 459 and 460 (Single Level Spinal Fusion Except Cervical with 
and without MCC, respectively) and below MS-DRGs 456, 457, and 458.
    Lastly, as discussed in section II.C.9. of the preamble of this 
proposed rule, we are proposing to revise the surgical hierarchy for 
the MDC 17 (Myeloproliferative Diseases and Disorders, Poorly 
Differentiated Neoplasms) MS-DRGs as follows: For the MDC 17 MS-DRGs, 
we are proposing to sequence proposed new MS-DRG 850 (Acute Leukemia 
with Other Procedures) above MS-DRGs 823, 824 and 825 (Lymphoma and 
Non-Acute Leukemia with Other Procedures with MCC, with CC, and without 
CC/MCC, respectively) and below MS-DRGs 820, 821, and 822 (Lymphoma and 
Leukemia with Major O.R. Procedures with MCC, with CC, and without CC/
MCC, respectively).
    Our proposal for Appendix D MS-DRG Surgical Hierarchy by MDC and 
MS-DRG of the ICD-10 MS-DRG Definitions Manual Version 42 is 
illustrated in the following tables.

15. Maintenance of the ICD-10-CM and ICD-10-PCS Coding Systems
    In September 1985, the ICD-9-CM Coordination and Maintenance 
Committee was formed. This is a Federal interdepartmental committee, 
co-chaired by the Centers for Disease Control and Prevention's (CDC) 
National Center for Health Statistics (NCHS) and CMS, charged with 
maintaining and updating the ICD-9-CM system. The final update to ICD-
9-CM codes was made on October 1, 2013. Thereafter, the name of the 
Committee was changed to the ICD-10 Coordination and Maintenance 
Committee, effective with the March 19-20, 2014 meeting. The ICD-10 
Coordination and Maintenance Committee addresses updates to the ICD- 
10-CM and ICD-10-PCS coding systems. The Committee is jointly 
responsible for approving coding changes, and developing errata, 
addenda, and other modifications to the coding systems to reflect newly 
developed procedures and technologies and newly identified diseases. 
The Committee is also responsible for promoting the use of Federal and 
non-Federal educational programs and other communication techniques 
with a view toward standardizing coding applications and upgrading the 
quality of the classification system.
    The official list of ICD-9-CM diagnosis and procedure codes by 
fiscal year can be found on the CMS website at: https://www.cms.gov/medicare/coding-billing/icd-10-codes/icd-9-cm-diagnosis-procedure-codes-abbreviated-and-full-code-titles.
    The official list of ICD-10-CM and ICD-10-PCS codes can be found on 
the CMS website at: http://www.cms.gov/Medicare/Coding/ICD10/index.html.
    The NCHS has lead responsibility for the ICD-10-CM and ICD-9-CM 
diagnosis codes included in the Tabular List and Alphabetic Index for 
Diseases, while CMS has lead responsibility for the ICD-10-PCS and ICD-
9-CM procedure codes included in the Tabular List and Alphabetic Index 
for Procedures.
    The Committee encourages participation in the previously mentioned 
process by health- related organizations. In this regard, the Committee 
holds public meetings for discussion of educational issues and

[[Page 36009]]

proposed coding changes. These meetings provide an opportunity for 
representatives of recognized organizations in the coding field, such 
as the American Health Information Management Association (AHIMA), the 
American Hospital Association (AHA), and various physician specialty 
groups, as well as individual physicians, health information management 
professionals, and other members of the public, to contribute ideas on 
coding matters. After considering the opinions expressed during the 
public meetings and in writing, the Committee formulates 
recommendations, which then must be approved by the agencies.
    The Committee presented proposals for coding changes for 
implementation in FY 2025 at a public meeting held on September 12-13, 
2023 and finalized the coding changes after consideration of comments 
received at the meetings and in writing by November 15, 2023.
    The Committee held its Spring 2024 meeting on March 19-20, 2024. 
The deadline for submitting comments on these code proposals is April 
19, 2024. It was announced at this meeting that any new diagnosis and 
procedure codes for which there was consensus of public support, and 
for which complete tabular and indexing changes would be made by June 
2024 would be included in the October 1, 2024 update to the ICD-10-CM 
diagnosis and ICD-10-PCS procedure code sets. As discussed in earlier 
sections of the preamble of this proposed rule, there are new, revised, 
and deleted ICD-10-CM diagnosis codes and ICD-10-PCS procedure codes 
that are captured in Table 6A.--New Diagnosis Codes, Table 6B.--New 
Procedure Codes, Table 6C.--Invalid Diagnosis Codes, Table 6D.--Invalid 
Procedure Codes, Table 6E.--Revised Diagnosis Code Titles, and Table 
6F.--Revised Procedure Code Titles for this proposed rule, which are 
available on the CMS website at: https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps.
    The code titles are adopted as part of the ICD-10 (previously ICD-
9-CM) Coordination and Maintenance Committee process. Therefore, 
although we make the code titles available for the IPPS proposed rule, 
they are not subject to comment in the proposed rule. Because of the 
length of these tables, they are not published in the Addendum to the 
proposed rule. Rather, they are available on the CMS website as 
discussed in section VI. of the Addendum to the proposed rule.
    Recordings for the virtual meeting discussions of the procedure 
codes at the Committee's September 12-13, 2023 meeting and the March 
19-20, 2024 meeting can be obtained from the CMS website at: https://www.cms.gov/Medicare/Coding/ICD10/C-and-M-Meeting-Materials. The 
materials for the discussions relating to diagnosis codes at the 
September 12-13, 2023 meeting and March 19-20, 2024 meeting can be 
found at: http://www.cdc.gov/nchs/icd/icd10cm_maintenance.html. These 
websites also provide detailed information about the Committee, 
including information on requesting a new code, participating in a 
Committee meeting, timeline requirements and meeting dates.
    We encourage commenters to submit questions and comments on coding 
issues involving diagnosis codes via Email to: cdc.gov">nchsicd10cm@cdc.gov.
    Questions and comments concerning the procedure codes should be 
submitted via Email to: [email protected].
    CMS implemented 41 new procedure codes including the insertion of a 
palladium-103 collagen implant into the brain, the excision or 
resection of intestinal body parts using a laparoscopic hand-assisted 
approach, the transfer of omentum for pedicled omentoplasty procedures, 
and the administration of talquetamab into the ICD-10-PCS 
classification effective with discharges on and after April 1, 2024. 
The procedure codes are as follows:

BILLING CODE 4120-01-C
    The 41 procedure codes are also reflected in Table 6B- New 
Procedure Codes, which is available on the CMS website at: https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS. We are soliciting public comments on the most 
appropriate MDC, MS-DRG, and operating room status assignments for 
these codes for FY 2025, as well as any other options for the GROUPER 
logic.
    We note that Change Request (CR) 13458, Transmittal 12384, titled 
``April 2024 Update to the Medicare Severity--Diagnosis Related Group 
(MS-DRG) Grouper and Medicare Code Editor (MCE) Version 41.1'' was 
issued on November 30, 2023 (available on the CMS website at: https://www.cms.gov/regulations-and-guidance/guidance/transmittals/2023-transmittals/r12384cp) regarding the release of an updated version of 
the ICD-10 MS-DRG GROUPER and Medicare Code Editor software, Version 
41.1, effective with discharges on and after April 1, 2024, reflecting 
the new procedure codes. The updated software, along with the updated 
ICD-10 MS-DRG Version 41.1 Definitions Manual and the Definitions of 
Medicare Code Edits Version 41.1 manual is available at: https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps/ms-drg-classifications-and-software.

    In the September 7, 2001 final rule implementing the IPPS new 
technology add-on payments (66 FR 46906), we indicated we would attempt 
to include proposals for procedure codes that would describe new 
technology discussed and approved at the Spring meeting as part of the 
code revisions effective the following October.
    Section 503(a) of the Medicare Modernization Act (Pub. L. 108-173) 
included a requirement for updating diagnosis and procedure codes twice 
a year instead of a single update on October 1 of each year. This 
requirement was included as part of the amendments to the Act relating 
to recognition of new technology under the IPPS. Section 503(a) of 
Public Law 108-173 amended section 1886(d)(5)(K) of the Act by adding a 
clause (vii) which states that the Secretary shall provide for the 
addition of new diagnosis and procedure codes on April 1 of each year, 
but the addition of such codes shall not require the Secretary to 
adjust the payment (or diagnosis-related group classification) until 
the fiscal year that begins after such date. This requirement improves 
the recognition of new technologies under the IPPS by providing 
information on these new technologies at an earlier date. Data will be 
available 6 months earlier than would be possible with updates 
occurring only once a year on October 1.
    In the FY 2005 IPPS final rule, we implemented section 
1886(d)(5)(K)(vii) of the Act, as added by section 503(a) of Public Law 
108-173, by developing a mechanism for approving, in time for the April 
update, diagnosis and procedure code revisions needed to describe new 
technologies and medical services for purposes of the new technology 
add-on payment process. We also established the following process for 
making these determinations. Topics considered during the Fall ICD-10 
(previously ICD-9-CM) Coordination and Maintenance Committee meeting 
were considered for an April 1 update if a strong and convincing case 
was made by the requestor during the Committee's public meeting. The 
request needed to identify the reason why a new code was needed in 
April for purposes of the new technology process. Meeting participants 
and those reviewing the Committee meeting materials were provided the 
opportunity to comment on the expedited request. We refer the reader to 
the FY 2022 IPPS/LTCH PPS final rule (86 FR 44950) for further 
discussion of the implementation of this prior April 1 update for 
purposes of the new technology add-on payment process.
    However, as discussed in the FY 2022 IPPS/LTCH PPS final rule (86 
FR 44950 through 44956), we adopted an April 1 implementation date, in 
addition to the annual October 1 update, beginning with April 1, 2022. 
We noted that the intent of this April 1 implementation date is to 
allow flexibility in the ICD-10 code update process. With this new 
April 1 update, CMS now uses the same process for consideration of all 
requests for an April 1 implementation date, including for purposes of 
the new technology add-on payment process (that is, the prior process 
for consideration of an April 1 implementation date only if a strong 
and convincing case was made by the requestor during the meeting no 
longer applies). We are continuing to use several aspects of our 
existing established process to implement new codes through the April 1 
code update, which includes presenting proposals for April 1 
consideration at the September ICD-10 Coordination and Maintenance 
Committee meeting, requesting public comments, reviewing the public 
comments, finalizing codes, and announcing the new codes with their 
assignments consistent with the new GROUPER release information. We 
note that under our established process, requestors indicate whether 
they are submitting their code request for consideration for an April 1 
implementation date or an October 1 implementation date. The ICD-10 
Coordination and Maintenance Committee makes efforts to accommodate the 
requested implementation date for each request submitted. However, the 
Committee determines which requests are to be presented for 
consideration for an April 1 implementation date or an October 1 
implementation date. As discussed earlier in this section of the 
preamble of this proposed rule, there were code proposals presented for 
an April 1, 2024 implementation at the September 12-13, 2023 Committee 
meetings. Following the receipt of public comments, the code proposals 
were approved and finalized, therefore, there were new codes 
implemented April 1, 2024.
    Consistent with the process we outlined for the April 1 
implementation date, we announced the new codes in November 2023 and 
provided the updated code files in December 2023 and ICD-10-CM Official 
Guidelines for Coding and Reporting in January 2024. In the February 
05, 2024 Federal Register (89 FR 7710), notice for the March 19-20, 
2024 ICD-10 Coordination and Maintenance Committee Meeting was 
published that includes the tentative agenda and identifies which 
topics are related to a new technology add-on payment application. By 
February 1, 2024 we made available the updated Version 41.1 ICD-10 MS-
DRG GROUPER software and related materials on the CMS web page at: 
https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps/ms-drg-classifications-and-software.
    ICD-9-CM addendum and code title information is published on the 
CMS website at https://www.cms.gov/medicare/coding-billing/icd-10-codes/updates-revisions-icd-9-cm-procedure-codes-addendum. ICD-10-CM 
and ICD-10-PCS addendum and code title information is published on the 
CMS website at https://www.cms.gov/medicare/coding-billing/icd-10-codes. CMS also sends electronic files containing all ICD-10-CM and 
ICD-10-PCS coding changes to its Medicare contractors for use in 
updating their systems and providing education to providers. 
Information on ICD-10-CM diagnosis codes, along with the Official ICD-
10-CM Coding Guidelines, can be found on the CDC website at https://www.cdc.gov/nchs/icd/Comprehensive-Listing-of-ICD-10-CM-Files.htm.
    Additionally, information on new, revised, and deleted ICD-10-CM 
diagnosis and ICD-10-PCS procedure codes is provided to the AHA for 
publication in the Coding Clinic for ICD-10. The AHA also distributes 
coding update information to publishers and software vendors.
    For FY 2024, there are currently 74,044 diagnosis codes and 78,638 
procedure codes. As displayed in Table 6A.--New Diagnosis Codes and in 
Table 6B.--New Procedure Codes associated with this proposed rule (and 
available on the CMS website at https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps), there are 252 new 
diagnosis codes that have been finalized for FY 2025 at the time of the 
development of this proposed rule and 41 new procedure codes that were 
effective with discharges on and after April 1, 2024. The code titles 
are adopted as part of the ICD-10 Coordination and Maintenance 
Committee process. Thus, although we publish the code titles in the 
IPPS proposed and final rules, they are not subject to comment in the 
proposed or final rules. We will continue to provide the October 
updates in this manner in the IPPS proposed and final rules.

16. Replaced Devices Offered Without Cost or With a Credit
a. Background
    In the FY 2008 IPPS final rule with comment period (72 FR 47246 
through 47251), we discussed the topic of Medicare payment for devices 
that are replaced without cost or where credit for a replaced device is 
furnished to the hospital. We implemented a policy to reduce a 
hospital's IPPS payment for certain MS-DRGs where the implantation of a 
device that subsequently failed or was recalled determined the base MS-
DRG assignment. At that time, we specified that we will reduce a 
hospital's IPPS payment for those MS-DRGs where the hospital received a 
credit for a replaced device equal to 50 percent or more of the cost of 
the device.
    In the FY 2012 IPPS/LTCH PPS final rule (76 FR 51556 through 
51557), we clarified this policy to state that the policy applies if 
the hospital received a credit equal to 50 percent or more of the cost 
of the replacement device and issued instructions to hospitals 
accordingly.
b. Proposed Changes for FY 2025
    As discussed in section II.C.5. of the preamble of this proposed 
rule, for FY 2025, we are proposing to revise the title of MS-DRG 276 
from ``Cardiac Defibrillator Implant with MCC'' to ``Cardiac 
Defibrillator Implant with MCC or Carotid Sinus Neurostimulator''.
    As stated in the FY 2016 IPPS/LTCH PPS proposed rule (80 FR 24409), 
we generally map new MS-DRGs onto the list when they are formed from 
procedures previously assigned to MS-DRGs that are already on the list. 
Currently, MS-DRG 276 is on the list of MS-DRGs subject to the policy 
for payment under the IPPS for replaced devices offered without cost or 
with a credit as shown in the following table. Therefore, we are 
proposing that if the applicable proposed MS-DRG changes are finalized, 
we would make conforming changes to the title of MS-DRG 276 as 
reflected in the table that follows. We are also proposing to continue 
to include the existing MS-DRGs currently subject to the policy as 
displayed in the following table.
BILLING CODE 4120-01-P

[GRAPHIC] [TIFF OMITTED] TP02MY24.073

BILLING CODE 4120-01-C
    The final list of MS-DRGs subject to the IPPS policy for replaced 
devices offered without cost or with a credit will be included in the 
FY 2025 IPPS/LTCH PPS final rule and also will be issued to providers 
in the form of a Change Request (CR).

D. Recalibration of the FY 2025 MS-DRG Relative Weights

1. Data Sources for Developing the Relative Weights
    Consistent with our established policy, in developing the MS-DRG 
relative weights for FY 2025, we propose to use two data sources: 
claims data and cost report data. The claims data source is the MedPAR 
file, which includes fully coded diagnostic and procedure data for all 
Medicare inpatient hospital bills. The FY 2023 MedPAR data used in this 
proposed rule include discharges occurring on October 1, 2022, through 
September 30, 2023, based on bills received by CMS through December 31, 
2023, from all hospitals subject to the IPPS and short-term, acute care 
hospitals in Maryland (which at that time were under a waiver from the 
IPPS).
    The FY 2023 MedPAR file used in calculating the relative weights 
includes data for approximately 6,887,902 Medicare discharges from IPPS 
providers. Discharges for Medicare beneficiaries enrolled in a Medicare 
Advantage managed care plan are excluded from this analysis. These 
discharges are excluded when the MedPAR ``GHO Paid'' indicator field on 
the claim record is equal to ``1'' or when the MedPAR DRG payment 
field, which represents the total payment for the claim, is equal to 
the MedPAR ``Indirect Medical Education (IME)'' payment field, 
indicating that the claim was an ``IME only'' claim submitted by a 
teaching hospital on behalf of a beneficiary enrolled in a Medicare 
Advantage managed care plan. In addition, the December 2023 update of 
the FY 2023 MedPAR file complies with version 5010 of the X12 HIPAA 
Transaction and Code Set Standards, and includes a variable called 
``claim type.'' Claim type ``60'' indicates that the claim was an 
inpatient claim paid as fee-for-service. Claim types ``61,'' ``62,'' 
``63,'' and ``64'' relate to encounter claims, Medicare Advantage IME 
claims, and HMO no-pay claims. Therefore, the calculation of the 
proposed relative weights for FY 2025 also excludes claims with claim 
type values not equal to ``60.'' The data exclude CAHs, including 
hospitals that subsequently became CAHs after the period from which the 
data were taken. In addition, the data exclude Rural Emergency 
Hospitals (REHs), including hospitals that subsequently became REHs 
after the period from which the data were taken. We note that the 
proposed FY 2025 relative weights are based on the ICD-10-CM diagnosis 
codes and ICD-10-PCS procedure codes from the FY 2023 MedPAR claims 
data, grouped through the ICD-10 version of

[[Page 36017]]

the proposed FY 2025 GROUPER (Version 42).
    The second data source used in the cost-based relative weighting 
methodology is the Medicare cost report data files from the Healthcare 
Cost Report Information System (HCRIS). In general, we use the HCRIS 
dataset that is 3 years prior to the IPPS fiscal year. Specifically, 
for this proposed rule, we used the December 2023 update of the FY 2022 
HCRIS for calculating the FY 2025 cost-based relative weights. 
Consistent with our historical practice, for this FY 2025 proposed 
rule, we are providing the version of the HCRIS from which we 
calculated these 19 CCRs on the CMS website at https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS. Click on 
the link on the left side of the screen titled ``FY 2025 IPPS Proposed 
Rule Home Page'' or ``Acute Inpatient Files for Download.''
2. Methodology for Calculation of the Relative Weights
a. General
    We calculated the proposed FY 2025 relative weights based on 19 
CCRs. The methodology we are proposing to use to calculate the FY 2025 
MS-DRG cost-based relative weights based on claims data in the FY 2023 
MedPAR file and data from the FY 2022 Medicare cost reports is as 
follows:
     To the extent possible, all the claims were regrouped 
using the proposed FY 2025 MS-DRG classifications discussed in sections 
II.B. and II.C. of the preamble of this proposed rule.
     The transplant cases that were used to establish the 
relative weights for heart and heart-lung, liver and/or intestinal, and 
lung transplants (MS-DRGs 001, 002, 005, 006, and 007, respectively) 
were limited to those Medicare-approved transplant centers that have 
cases in the FY 2023 MedPAR file. (Medicare coverage for heart, heart-
lung, liver and/or intestinal, and lung transplants is limited to those 
facilities that have received approval from CMS as transplant centers.)
     Organ acquisition costs for kidney, heart, heart-lung, 
liver, lung, pancreas, and intestinal (or multivisceral organs) 
transplants continue to be paid on a reasonable cost basis.
    Because these acquisition costs are paid separately from the 
prospective payment rate, it is necessary to subtract the acquisition 
charges from the total charges on each transplant bill that showed 
acquisition charges before computing the average cost for each MS-DRG 
and before eliminating statistical outliers.
    Section 108 of the Further Consolidated Appropriations Act, 2020 
provides that, for cost reporting periods beginning on or after October 
1, 2020, costs related to hematopoietic stem cell acquisition for the 
purpose of an allogeneic hematopoietic stem cell transplant shall be 
paid on a reasonable cost basis. We refer the reader to the FY 2021 
IPPS/LTCH PPS final rule for further discussion of the reasonable cost 
basis payment for cost reporting periods beginning on or after October 
1, 2020 (85 FR 58835 through 58842). For FY 2022 and subsequent years, 
we subtract the hematopoietic stem cell acquisition charges from the 
total charges on each transplant bill that showed hematopoietic stem 
cell acquisition charges before computing the average cost for each MS-
DRG and before eliminating statistical outliers.
     Claims with total charges or total lengths of stay less 
than or equal to zero were deleted. Claims that had an amount in the 
total charge field that differed by more than $30.00 from the sum of 
the routine day charges, intensive care charges, pharmacy charges, 
implantable devices charges, supplies and equipment charges, therapy 
services charges, operating room charges, cardiology charges, 
laboratory charges, radiology charges, other service charges, labor and 
delivery charges, inhalation therapy charges, emergency room charges, 
blood and blood products charges, anesthesia charges, cardiac 
catheterization charges, CT scan charges, and MRI charges were also 
deleted.
     At least 92.6 percent of the providers in the MedPAR file 
had charges for 14 of the 19 cost centers. All claims of providers that 
did not have charges greater than zero for at least 14 of the 19 cost 
centers were deleted. In other words, a provider must have no more than 
five blank cost centers. If a provider did not have charges greater 
than zero in more than five cost centers, the claims for the provider 
were deleted.
     Statistical outliers were eliminated by removing all cases 
that were beyond 3.0 standard deviations from the geometric mean of the 
log distribution of both the total charges per case and the total 
charges per day for each MS-DRG.
     Effective October 1, 2008, because hospital inpatient 
claims include a Present on Admission (POA) field for each diagnosis 
present on the claim, only for purposes of relative weight-setting, the 
POA indicator field was reset to ``Y'' for ``Yes'' for all claims that 
otherwise have an ``N'' (No) or a ``U'' (documentation insufficient to 
determine if the condition was present at the time of inpatient 
admission) in the POA field.
    Under current payment policy, the presence of specific HAC codes, 
as indicated by the POA field values, can generate a lower payment for 
the claim. Specifically, if the particular condition is present on 
admission (that is, a ``Y'' indicator is associated with the diagnosis 
on the claim), it is not a HAC, and the hospital is paid for the higher 
severity (and, therefore, the higher weighted MS-DRG). If the 
particular condition is not present on admission (that is, an ``N'' 
indicator is associated with the diagnosis on the claim) and there are 
no other complicating conditions, the DRG GROUPER assigns the claim to 
a lower severity (and, therefore, the lower weighted MS-DRG) as a 
penalty for allowing a Medicare inpatient to contract a HAC. While the 
POA reporting meets policy goals of encouraging quality care and 
generates program savings, it presents an issue for the relative 
weight-setting process. Because cases identified as HACs are likely to 
be more complex than similar cases that are not identified as HACs, the 
charges associated with HAC cases are likely to be higher as well. 
Therefore, if the higher charges of these HAC claims are grouped into 
lower severity MS-DRGs prior to the relative weight-setting process, 
the relative weights of these particular MS-DRGs would become 
artificially inflated, potentially skewing the relative weights. In 
addition, we want to protect the integrity of the budget neutrality 
process by ensuring that, in estimating payments, no increase to the 
standardized amount occurs as a result of lower overall payments in a 
previous year that stem from using weights and case-mix that are based 
on lower severity MS-DRG assignments. If this would occur, the 
anticipated cost savings from the HAC policy would be lost.
    To avoid these problems, we reset the POA indicator field to ``Y'' 
only for relative weight-setting purposes for all claims that otherwise 
have an ``N'' or a ``U'' in the POA field. This resetting ``forced'' 
the more costly HAC claims into the higher severity MS-DRGs as 
appropriate, and the relative weights calculated for each MS-DRG more 
closely reflect the true costs of those cases.
    In addition, in the FY 2013 IPPS/LTCH PPS final rule, for FY 2013 
and subsequent fiscal years, we finalized a policy to treat hospitals 
that participate in the Bundled Payments for Care Improvement (BPCI) 
initiative the same as prior fiscal years for the IPPS payment modeling 
and ratesetting

[[Page 36018]]

process without regard to hospitals' participation within these bundled 
payment models (77 FR 53341 through 53343). Specifically, because acute 
care hospitals participating in the BPCI Initiative still receive IPPS 
payments under section 1886(d) of the Act, we include all applicable 
data from these subsection (d) hospitals in our IPPS payment modeling 
and ratesetting calculations as if the hospitals were not participating 
in those models under the BPCI initiative. We refer readers to the FY 
2013 IPPS/LTCH PPS final rule for a complete discussion on our final 
policy for the treatment of hospitals participating in the BPCI 
initiative in our ratesetting process. For additional information on 
the BPCI initiative, we refer readers to the CMS' Center for Medicare 
and Medicaid Innovation's website at https://innovation.cms.gov/initiatives/Bundled-Payments/index.html and to section IV.H.4. of the 
preamble of the FY 2013 IPPS/LTCH PPS final rule (77 FR 53341 through 
53343).
    The participation of hospitals in the BPCI initiative concluded on 
September 30, 2018. The participation of hospitals in the BPCI Advanced 
model started on October 1, 2018. The BPCI Advanced model, tested under 
the authority of section 1115A of the Act, is comprised of a single 
payment and risk track, which bundles payments for multiple services 
that beneficiaries receive during a Clinical Episode. Acute care 
hospitals may participate in BPCI Advanced in one of two capacities: as 
a model Participant or as a downstream Episode Initiator. Regardless of 
the capacity in which they participate in the BPCI Advanced model, 
participating acute care hospitals will continue to receive IPPS 
payments under section 1886(d) of the Act. Acute care hospitals that 
are Participants also assume financial and quality performance 
accountability for Clinical Episodes in the form of a reconciliation 
payment. For additional information on the BPCI Advanced model, we 
refer readers to the BPCI Advanced web page on the CMS Center for 
Medicare and Medicaid Innovation's website at https://innovation.cms.gov/initiatives/bpci-advanced. Consistent with our 
policy for FY 2024, and consistent with how we have treated hospitals 
that participated in the BPCI Initiative, for FY 2025, we continue to 
believe it is appropriate to include all applicable data from the 
subsection (d) hospitals participating in the BPCI Advanced model in 
our IPPS payment modeling and ratesetting calculations because, as 
noted previously, these hospitals are still receiving IPPS payments 
under section 1886(d) of the Act. Consistent with the FY 2024 IPPS/LTCH 
PPS final rule, we are also proposing to include all applicable data 
from subsection (d) hospitals participating in the Comprehensive Care 
for Joint Replacement (CJR) Model in our IPPS payment modeling and 
ratesetting calculations.
    The charges for each of the 19 cost groups for each claim were 
standardized to remove the effects of differences in area wage levels, 
IME and DSH payments, and for hospitals located in Alaska and Hawaii, 
the applicable cost-of-living adjustment. Because hospital charges 
include charges for both operating and capital costs, we standardized 
total charges to remove the effects of differences in geographic 
adjustment factors, cost-of-living adjustments, and DSH payments under 
the capital IPPS as well. Charges were then summed by MS-DRG for each 
of the 19 cost groups so that each MS-DRG had 19 standardized charge 
totals. Statistical outliers were then removed. These charges were then 
adjusted to cost by applying the proposed national average CCRs 
developed from the FY 2022 cost report data.
    The 19 cost centers that we used in the relative weight calculation 
are shown in a supplemental data file, Cost Center HCRIS Lines 
Supplemental Data File, posted via the internet on the CMS website for 
this proposed rule and available at https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS. The supplemental 
data file shows the lines on the cost report and the corresponding 
revenue codes that we used to create the proposed 19 national cost 
center CCRs. If we receive comments about the groupings in this 
supplemental data file, we may consider these comments as we finalize 
our policy.
    Consistent with historical practice, we account for rare situations 
of non-monotonicity in a base MS-DRG and its severity levels, where the 
mean cost in the higher severity level is less than the mean cost in 
the lower severity level, in determining the relative weights for the 
different severity levels. If there are initially non-monotonic 
relative weights in the same base DRG and its severity levels, then we 
combine the cases that group to the specific non-monotonic MS-DRGs for 
purposes of relative weight calculations. For example, if there are two 
non-monotonic MS-DRGs, combining the cases across those two MS-DRGs 
results in the same relative weight for both MS-DRGs. The relative 
weight calculated using the combined cases for those severity levels is 
monotonic, effectively removing any non-monotonicity with the base DRG 
and its severity levels. For this FY 2025 proposed rule, this 
calculation was applied to address non-monotonicity for cases that 
grouped to the following: MS-DRG 016 and MS-DRG 017, MS-DRG 095 and MS-
DRG 096, MS-DRG 504 and MS-DRG 505, MS-DRG 797 and MS-DRG 798. In the 
supplemental file titled AOR/BOR File, we include statistics for the 
affected MS-DRGs both separately and with cases combined.
    We are inviting public comments on our proposals related to 
recalibration of the proposed FY 2025 relative weights and the changes 
in relative weights from FY 2024.
b. Relative Weight Calculation for MS-DRG 018
    In the FY 2021 IPPS/LTCH PPS final rule (85 FR 58451 through 
58453), we created MS-DRG 018 for cases that include procedures 
describing CAR T-cell therapies. We also finalized our proposal to 
modify our existing relative weight methodology to ensure that the 
relative weight for MS-DRG 018 appropriately reflects the relative 
resources required for providing CAR T-cell therapy outside of a 
clinical trial, while still accounting for the clinical trial cases in 
the overall average cost for all MS-DRGs (85 FR 58599 through 58600). 
Specifically, we stated that clinical trial claims that group to new 
MS-DRG 018 would not be included when calculating the average cost for 
MS-DRG 018 that is used to calculate the relative weight for this MS-
DRG, so that the relative weight reflects the costs of the CAR T-cell 
therapy drug. We stated that we identified clinical trial claims as 
claims that contain ICD-10-CM diagnosis code Z00.6 or contain 
standardized drug charges of less than $373,000, which was the average 
sales price of KYMRIAH and YESCARTA, the two CAR T-cell biological 
products licensed to treat relapsed/refractory large B-cell lymphoma as 
of the time of the development of the FY 2021 final rule. In addition, 
we stated that (a) when the CAR T-cell therapy product is purchased in 
the usual manner, but the case involves a clinical trial of a different 
product, the claim will be included when calculating the average cost 
for new MS-DRG 018 to the extent such cases can be identified in the 
historical data, and (b) when there is expanded access use of 
immunotherapy, these cases will not be included when calculating the 
average cost for new MS-DRG 018 to the extent such cases can be 
identified in the historical data.
    We also finalized our proposal to calculate an adjustment to 
account for

[[Page 36019]]

the CAR T-cell therapy cases identified as clinical trial cases in 
calculating the national average standardized cost per case that is 
used to calculate the relative weights for all MS-DRGs and for purposes 
of budget neutrality and outlier simulations. We calculate this 
adjustor by dividing the average cost for cases that we identify as 
clinical trial cases by the average cost for cases that we identify as 
non-clinical trial cases, with the additional refinements that (a) when 
the CAR T-cell therapy product is purchased in the usual manner, but 
the case involves a clinical trial of a different product, the claim 
will be included when calculating the average cost for cases not 
determined to be clinical trial cases to the extent such cases can be 
identified in the historical data, and (b) when there is expanded 
access use of immunotherapy, these cases will be included when 
calculating the average cost for cases determined to be clinical trial 
cases to the extent such cases can be identified in the historical 
data. We stated that to the best of our knowledge, there were no claims 
in the historical data used in the calculation of this adjustment for 
cases involving a clinical trial of a different product, and to the 
extent the historical data contain claims for cases involving expanded 
access use of immunotherapy we believe those claims would have drug 
charges less than $373,000.
    In the FY 2021 IPPS/LTCH PPS final rule (85 FR 58842), we also 
finalized an adjustment to the payment amount for applicable clinical 
trial and expanded access use immunotherapy cases that group to MS-DRG 
018, and indicated that we would provide instructions for identifying 
these claims in separate guidance. Following the issuance of the FY 
2021 IPPS/LTCH PPS final rule, we issued guidance \15\ stating that 
providers may enter a Billing Note NTE02 ``Expand Acc Use'' on the 
electronic claim 837I or a remark ``Expand Acc Use'' on a paper claim 
to notify the MAC of expanded access use of CAR T-cell therapy. In this 
case, the MAC would add payer-only condition code ``ZB'' so that Pricer 
will apply the payment adjustment in calculating payment for the case. 
In cases when the CAR T-cell therapy product is purchased in the usual 
manner, but the case involves a clinical trial of a different product, 
the provider may enter a Billing Note NTE02 ``Diff Prod Clin Trial'' on 
the electronic claim 837I or a remark ``Diff Prod Clin Trial'' on a 
paper claim. In this case, the MAC would add payer-only condition code 
``ZC'' so that the Pricer will not apply the payment adjustment in 
calculating payment for the case.

---------------------------------------------------------------------------

    In the FY 2022 IPPS/LTCH PPS final rule, we revised MS-DRG 018 to 
include cases that report the procedure codes for CAR T-cell and non-
CAR T-cell therapies and other immunotherapies (86 FR 44798 through 
44806). We also finalized our proposal to continue to use the proxy of 
standardized drug charges of less than $373,000 (86 FR 44965) to 
identify clinical trial claims. We also finalized use of this same 
proxy for the FY 2023 IPPS/LTCH PPS final rule (87 FR 48894).
    Following the issuance of the FY 2023 IPPS/LTCH PPS final rule, we 
issued guidance \16\ stating where there is expanded access use of 
immunotherapy, the provider may submit condition code ``90'' on the 
claim so that Pricer will apply the payment adjustment in calculating 
payment for the case. We stated that MACs would no longer append 
Condition Code `ZB' to inpatient claims reporting Billing Note NTE02 
``Expand Acc Use'' on the electronic claim 837I or a remark ``Expand 
Acc Use'' on a paper claim, effective for claims for discharges that 
occur on or after October 1, 2022.
---------------------------------------------------------------------------

    \16\ https://www.cms.gov/files/document/r11727cp.pdf.
---------------------------------------------------------------------------

    In the FY 2024 IPPS/LTCH PPS final rule, we explained that the 
MedPAR claims data now includes a field that identifies whether or not 
the claim includes expanded access use of immunotherapy. We stated that 
for the FY 2022 MedPAR claims data, this field identifies whether or 
not the claim includes condition code ZB, and for the FY 2023 MedPAR 
data and subsequent years, this field will identify whether or not the 
claim includes condition code 90. We further noted that the MedPAR 
files now also include a variable that indicates whether the claim 
includes the payer-only condition code ``ZC'', which identifies a case 
involving the clinical trial of a different product where the CAR T-
cell, non-CAR T-cell, or other immunotherapy product is purchased in 
the usual manner.
    Accordingly, and as discussed further in the FY 2024 IPPS/LTCH PPS 
final rule, we finalized two modifications to our methodology for 
identifying clinical trial claims and expanded access use claims in MS-
DRG 018 (88 FR 58791). First, we finalized to exclude claims with the 
presence of condition code ``90'' (or, for FY 2024 ratesetting, which 
was based on the FY 2022 MedPAR data, the presence of condition code 
``ZB'') and claims that contain ICD-10-CM diagnosis code Z00.6 without 
payer-only code ``ZC'' that group to MS-DRG 018 when calculating the 
average cost for MS-DRG 018. Second, we finalized to no longer use the 
proxy of standardized drug charges of less than $373,000 to identify 
clinical trial claims and expanded access use cases when calculating 
the average cost for MS-DRG 018. Accordingly, we finalized that in 
calculating the relative weight for MS-DRG 018 for FY 2024, only those 
claims that group to MS-DRG 018 that (1) contain ICD-10-CM diagnosis 
code Z00.6 and do not include payer-only code ``ZC'' or (2) contain 
condition code ``ZB'' (or, for subsequent fiscal years, condition code 
``90'') would be excluded from the calculation of the average cost for 
MS-DRG 018. Consistent with this, we also finalized modifications to 
our calculation of the adjustment to account for the CAR T-cell therapy 
cases identified as clinical trial cases in calculating the national 
average standardized cost per case that is used to calculate the 
relative weights for all MS-DRGs. We refer readers to the FY 2024 IPPS/
LTCH PPS final rule for further discussion of these modifications (88 
FR 58791).
    In this FY 2025 IPPS/LTCH PPS proposed rule, we are proposing to 
continue to use our methodology as modified in the FY 2024 IPPS/LTCH 
PPS final rule for identifying clinical trial claims and expanded 
access use claims in MS-DRG 018. First, we exclude claims with the 
presence of condition code ``90'' and claims that contain ICD-10-CM 
diagnosis code Z00.6 without payer-only code ``ZC'' that group to MS-
DRG 018 when calculating the average cost for MS-DRG 018. Second, we no 
longer use the proxy of standardized drug charges of less than $373,000 
to identify clinical trial claims and expanded access use cases when 
calculating the average cost for MS-DRG 018. Accordingly, we are 
proposing that in calculating the relative weight for MS-DRG 018 for FY 
2025, only those claims that group to MS-DRG 018 that (1) contain ICD-
10-CM diagnosis code Z00.6 and do not include payer-only code ``ZC'' or 
(2) contain condition code ``90'' would be excluded from the 
calculation of the average cost for MS-DRG 018.
    We are also proposing to continue to use the methodology as 
modified in the FY 2024 IPPS/LTCH PPS final rule to calculate the 
adjustment to account for the CAR T-cell therapy cases identified as 
clinical trial cases in calculating the national average standardized 
cost per case that is used to calculate the relative weights for all 
MS-DRGs:

[[Page 36020]]

     Calculate the average cost for cases assigned to MS-DRG 
018 that either (a) contain ICD-10-CM diagnosis code Z00.6 and do not 
contain condition code ``ZC'' or (b) contain condition code ``90''.
     Calculate the average cost for all other cases assigned to 
MS-DRG 018.
     Calculate an adjustor by dividing the average cost 
calculated in step 1 by the average cost calculated in step 2.
     Apply the adjustor calculated in step 3 to the cases 
identified in step 1 as applicable clinical trial or expanded access 
use cases, then add this adjusted case count to the non-clinical trial 
case count prior to calculating the average cost across all MS-DRGs.
    Under our proposal to continue to apply this methodology, based on 
the December 2023 update of the FY 2023 MedPAR file used for this 
proposed rule, we estimated that the average costs of cases assigned to 
MS-DRG 018 that are identified as clinical trial cases ($116,831) were 
34 percent of the average costs of the cases assigned to MS-DRG 018 
that are identified as non-clinical trial cases ($342,684). 
Accordingly, as we did for FY 2024, we are proposing to adjust the 
transfer-adjusted case count for MS-DRG 018 by applying the proposed 
adjustor of 0.34 to the applicable clinical trial and expanded access 
use immunotherapy cases, and to use this adjusted case count for MS-DRG 
018 in calculating the national average cost per case, which is used in 
the calculation of the relative weights. Therefore, in calculating the 
national average cost per case for purposes of this proposed rule, each 
case identified as an applicable clinical trial or expanded access use 
immunotherapy case was adjusted by 0.34. As we did for FY 2024, we are 
applying this same adjustor for the applicable cases that group to MS-
DRG 018 for purposes of budget neutrality and outlier simulations. We 
are also proposing to update the value of the adjustor based on more 
recent data for the final rule.
d. Cap for Relative Weight Reductions
    In the FY 2023 IPPS/LTCH PPS final rule, we finalized a permanent 
10-percent cap on the reduction in an MS-DRG's relative weight in a 
given fiscal year, beginning in FY 2023. We also finalized a budget 
neutrality adjustment to the standardized amount for all hospitals to 
ensure that application of the permanent 10-percent cap does not result 
in an increase or decrease of estimated aggregate payments. We refer 
the reader to the FY 2023 IPPS/LTCH PPS final rule for further 
discussion of this policy. In the Addendum to this IPPS/LTCH PPS 
proposed rule, we present the proposed budget neutrality adjustment for 
reclassification and recalibration of the FY 2025 MS-DRG relative 
weights with application of this cap. We are also making available on 
the CMS website a supplemental file demonstrating the application of 
the permanent 10 percent cap for FY 2025. For a further discussion of 
the proposed budget neutrality adjustment for FY 2025, we refer readers 
to the Addendum of this proposed rule.
3. Development of Proposed National Average Cost-To-Charge Ratios 
(CCRs)
    We developed the proposed national average CCRs as follows:
    Using the FY 2022 cost report data, we removed CAHs, Indian Health 
Service hospitals, all-inclusive rate hospitals, and cost reports that 
represented time periods of less than 1 year (365 days). We included 
hospitals located in Maryland because we include their charges in our 
claims database. Then we created CCRs for each provider for each cost 
center (see the supplemental data file for line items used in the 
calculations) and removed any CCRs that were greater than 10 or less 
than 0.01. We normalized the departmental CCRs by dividing the CCR for 
each department by the total CCR for the hospital for the purpose of 
trimming the data. Then we took the logs of the normalized cost center 
CCRs and removed any cost center CCRs where the log of the cost center 
CCR was greater or less than the mean log plus/minus 3 times the 
standard deviation for the log of that cost center CCR. Once the cost 
report data were trimmed, we calculated a Medicare-specific CCR. The 
Medicare-specific CCR was determined by taking the Medicare charges for 
each line item from Worksheet D-3 and deriving the Medicare-specific 
costs by applying the hospital-specific departmental CCRs to the 
Medicare-specific charges for each line item from Worksheet D-3. Once 
each hospital's Medicare-specific costs were established, we summed the 
total Medicare-specific costs and divided by the sum of the total 
Medicare-specific charges to produce national average, charge-weighted 
CCRs.
    After we multiplied the total charges for each MS-DRG in each of 
the 19 cost centers by the corresponding national average CCR, we 
summed the 19 ``costs'' across each MS-DRG to produce a total 
standardized cost for the MS-DRG. The average standardized cost for 
each MS-DRG was then computed as the total standardized cost for the 
MS-DRG divided by the transfer-adjusted case count for the MS-DRG. The 
average cost for each MS-DRG was then divided by the national average 
standardized cost per case to determine the proposed relative weight. 
The proposed FY 2025 cost-based relative weights were then normalized 
by an adjustment factor of 1.92287 so that the average case weight 
after recalibration was equal to the average case weight before 
recalibration. The normalization adjustment is intended to ensure that 
recalibration by itself neither increases nor decreases total payments 
under the IPPS, as required by section 1886(d)(4)(C)(iii) of the Act. 
We then applied the permanent 10-percent cap on the reduction in a MS-
DRG's relative weight in a given fiscal year; specifically for those 
MS-DRGs for which the relative weight otherwise would have declined by 
more than 10 percent from the FY 2024 relative weight, we set the 
proposed FY 2025 relative weight equal to 90 percent of the FY 2024 
relative weight. The proposed relative weights for FY 2025 as set forth 
in Table 5 associated with this proposed rule and available on the CMS 
website at https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS reflect the application of this cap.
    The proposed 19 national average CCRs for FY 2025 are as follows:

[[Page 36021]]

    Since FY 2009, the relative weights have been based on 100 percent 
cost weights based on our MS-DRG grouping system.
    When we recalibrated the DRG weights for previous years, we set a 
threshold of 10 cases as the minimum number of cases required to 
compute a reasonable weight. We are proposing to use that same case 
threshold in recalibrating the proposed MS-DRG relative weights for FY 
2025. Using data from the FY 2023 MedPAR file, there were 8 MS-DRGs 
that contain fewer than 10 cases. For FY 2025, because we do not have 
sufficient MedPAR data to set accurate and stable cost relative weights 
for these low-volume MS-DRGs, we are proposing to compute relative 
weights for the low-volume MS-DRGs by adjusting their final FY 2024 
relative weights by the percentage change in the average weight of the 
cases in other MS-DRGs from FY 2024 to FY 2025. The crosswalk table is 
as follows.

E. Add-On Payments for New Services and Technologies for FY 2025

1. Background
    Effective for discharges beginning on or after October 1, 2001, 
section 1886(d)(5)(K)(i) of the Act requires the Secretary to establish 
(after notice and opportunity for public comment) a mechanism to 
recognize the costs of new medical services and technologies (sometimes 
collectively referred to in this section as ``new technologies'') under 
the IPPS. Section 1886(d)(5)(K)(vi) of the Act specifies that a medical 
service or technology will be considered new if it meets criteria 
established by the Secretary after notice and opportunity for public 
comment. Section 1886(d)(5)(K)(ii)(I) of the Act specifies that a new 
medical service or technology may be considered for new technology add-
on payment if, based on the estimated costs incurred with respect to 
discharges involving such service or technology, the DRG prospective 
payment rate otherwise applicable to such discharges under this 
subsection is inadequate. The regulations at 42 CFR 412.87 implement 
these provisions and Sec.  412.87(b) specifies three criteria for a new 
medical service or technology to receive the additional payment: (1) 
The medical service or technology must be new; (2) the medical service 
or technology must be costly such that the DRG rate otherwise 
applicable to discharges involving the medical service or technology is 
determined to be inadequate; and (3) the service or technology must 
demonstrate a substantial clinical improvement over existing services 
or technologies. In addition, certain transformative new devices and 
antimicrobial products may qualify under an alternative inpatient new 
technology add-on payment pathway, as set forth in the regulations at 
Sec.  412.87(c) and (d).
    We note that section 1886(d)(5)(K)(i) of the Act requires that the 
Secretary establish a mechanism to recognize the costs of new medical 
services and technologies under the payment system established under 
that subsection, which establishes the system for paying for the 
operating costs of inpatient hospital services. The system of payment 
for capital costs is established under section 1886(g) of the Act. 
Therefore, as discussed in prior rulemaking (72 FR 47307 through 
47308), we do not include capital costs in the add-on payments for a 
new medical service or technology or make new technology add-on 
payments under the IPPS for capital-related costs.
    In this rule, we highlight some of the major statutory and 
regulatory provisions relevant to the new technology add-on payment 
criteria, as well as other information. For further discussion on the 
new technology add-on payment criteria, we refer readers to the FY 2012 
IPPS/LTCH PPS final rule (76 FR 51572 through 51574), the FY 2020 IPPS/
LTCH PPS final rule (84 FR 42288 through 42300), and the FY 2021 IPPS/
LTCH PPS final rule (85 FR 58736 through 58742).
a. New Technology Add-on Payment Criteria
(1) Newness Criterion
    Under the first criterion, as reflected in Sec.  412.87(b)(2), a 
specific medical service or technology will no longer be considered 
``new'' for purposes of new medical service or technology add-on 
payments after CMS has recalibrated the MS-DRGs, based on available 
data, to reflect the cost of the technology. We note that we do not 
consider a service or technology to be new if it is substantially 
similar to one or more existing technologies. That is, even if a 
medical product receives a new FDA approval or clearance, it may not 
necessarily be considered ``new'' for purposes of new technology add-on 
payments if it is ``substantially similar''

[[Page 36023]]

to another medical product that was approved or cleared by FDA and has 
been on the market for more than 2 to 3 years. In the FY 2010 IPPS/RY 
2010 LTCH PPS final rule (74 FR 43813 through 43814), we established 
criteria for evaluating whether a new technology is substantially 
similar to an existing technology, specifically whether: (1) a product 
uses the same or a similar mechanism of action to achieve a therapeutic 
outcome; (2) a product is assigned to the same or a different MS-DRG; 
and (3) the new use of the technology involves the treatment of the 
same or similar type of disease and the same or similar patient 
population. If a technology meets all three of these criteria, it would 
be considered substantially similar to an existing technology and would 
not be considered ``new'' for purposes of new technology add-on 
payments. For a detailed discussion of the criteria for substantial 
similarity, we refer readers to the FY 2006 IPPS final rule (70 FR 
47351 through 47352) and the FY 2010 IPPS/LTCH PPS final rule (74 FR 
43813 through 43814).
(2) Cost Criterion
    Under the second criterion, Sec.  412.87(b)(3) further provides 
that, to be eligible for the add-on payment for new medical services or 
technologies, the MS-DRG prospective payment rate otherwise applicable 
to discharges involving the new medical service or technology must be 
assessed for adequacy. Under the cost criterion, consistent with the 
formula specified in section 1886(d)(5)(K)(ii)(I) of the Act, to assess 
the adequacy of payment for a new technology paid under the applicable 
MS-DRG prospective payment rate, we evaluate whether the charges of the 
cases involving a new medical service or technology will exceed a 
threshold amount that is the lesser of 75 percent of the standardized 
amount (increased to reflect the difference between cost and charges) 
or 75 percent of one standard deviation beyond the geometric mean 
standardized charge for all cases in the MS-DRG to which the new 
medical service or technology is assigned (or the case-weighted average 
of all relevant MS-DRGs if the new medical service or technology occurs 
in many different MS-DRGs). The MS-DRG threshold amounts generally used 
in evaluating new technology add-on payment applications for FY 2025 
are presented in a data file that is available, along with the other 
data files associated with the FY 2024 IPPS/LTCH PPS final rule and 
correction notification, on the CMS website at: https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/index.
    We note that, under the policy finalized in the FY 2021 IPPS/LTCH 
PPS final rule (85 FR 58603 through 58605), beginning with FY 2022, we 
use the proposed threshold values associated with the proposed rule for 
that fiscal year to evaluate the cost criterion for all applications 
for new technology add-on payments and previously approved technologies 
that may continue to receive new technology add-on payments, if those 
technologies would be assigned to a proposed new MS-DRG for that same 
fiscal year.
    As finalized in the FY 2019 IPPS/LTCH PPS final rule (83 FR 41275), 
beginning with FY 2020, we include the thresholds applicable to the 
next fiscal year (previously included in Table 10 of the annual IPPS/
LTCH PPS proposed and final rules) in the data files associated with 
the prior fiscal year. Accordingly, the proposed thresholds for 
applications for new technology add-on payments for FY 2026 are 
presented in a data file that is available on the CMS website, along 
with the other data files associated with the FY 2025 proposed rule, by 
clicking on the FY 2025 IPPS Proposed Rule Home Page at: https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/index.
    In the September 7, 2001 final rule that established the new 
technology add-on payment regulations (66 FR 46917), we discussed that 
applicants should submit a significant sample of data to demonstrate 
that the medical service or technology meets the high-cost threshold. 
Specifically, applicants should submit a sample of sufficient size to 
enable us to undertake an initial validation and analysis of the data. 
We also discussed in the September 7, 2001 final rule (66 FR 46917) the 
issue of whether the Health Insurance Portability and Accountability 
Act (HIPAA) Privacy Rule at 45 CFR parts 160 and 164 applies to claims 
information that providers submit with applications for new medical 
service or technology add-on payments. We refer readers to the FY 2012 
IPPS/LTCH PPS final rule (76 FR 51573) for further information on this 
issue.
(3) Substantial Clinical Improvement Criterion
    Under the third criterion at Sec.  412.87(b)(1), a medical service 
or technology must represent an advance that substantially improves, 
relative to technologies previously available, the diagnosis or 
treatment of Medicare beneficiaries. In the FY 2020 IPPS/LTCH PPS final 
rule (84 FR 42288 through 42292), we prospectively codified in our 
regulations at Sec.  412.87(b) the following aspects of how we evaluate 
substantial clinical improvement for purposes of new technology add-on 
payments under the IPPS:
     The totality of the circumstances is considered when 
making a determination that a new medical service or technology 
represents an advance that substantially improves, relative to services 
or technologies previously available, the diagnosis or treatment of 
Medicare beneficiaries.
     A determination that a new medical service or technology 
represents an advance that substantially improves, relative to services 
or technologies previously available, the diagnosis or treatment of 
Medicare beneficiaries means--
    ++ The new medical service or technology offers a treatment option 
for a patient population unresponsive to, or ineligible for, currently 
available treatments;
    The new medical service or technology offers a treatment option for 
a patient population unresponsive to, or ineligible for, currently 
available treatments;
    The new medical service or technology offers the ability to 
diagnose a medical condition in a patient population where that medical 
condition is currently undetectable, or offers the ability to diagnose 
a medical condition earlier in a patient population than allowed by 
currently available methods, and there must also be evidence that use 
of the new medical service or technology to make a diagnosis affects 
the management of the patient. The new medical service or technology 
offers a treatment option for a patient population unresponsive to, or 
ineligible for, currently available treatments;
    The use of the new medical service or technology significantly 
improves clinical outcomes relative to services or technologies 
previously available as demonstrated by one or more of the following: a 
reduction in at least one clinically significant adverse event, 
including a reduction in mortality or a clinically significant 
complication; a decreased rate of at least one subsequent diagnostic or 
therapeutic intervention; a decreased number of future hospitalizations 
or physician visits; a more rapid beneficial resolution of the disease 
process treatment including, but not limited to, a reduced length of 
stay or recovery time; an improvement in one or more activities of 
daily living; an improved quality of life; or, a

[[Page 36024]]

demonstrated greater medication adherence or compliance; or
    ++ The totality of the circumstances otherwise demonstrates that 
the new medical service or technology substantially improves, relative 
to technologies previously available, the diagnosis or treatment of 
Medicare beneficiaries.
     Evidence from the following published or unpublished 
information sources from within the United States or elsewhere may be 
sufficient to establish that a new medical service or technology 
represents an advance that substantially improves, relative to services 
or technologies previously available, the diagnosis or treatment of 
Medicare beneficiaries: clinical trials, peer reviewed journal 
articles; study results; meta-analyses; consensus statements; white 
papers; patient surveys; case studies; reports; systematic literature 
reviews; letters from major healthcare associations; editorials and 
letters to the editor; and public comments. Other appropriate 
information sources may be considered.
     The medical condition diagnosed or treated by the new 
medical service or technology may have a low prevalence among Medicare 
beneficiaries.
     The new medical service or technology may represent an 
advance that substantially improves, relative to services or 
technologies previously available, the diagnosis or treatment of a 
subpopulation of patients with the medical condition diagnosed or 
treated by the new medical service or technology.
    We refer the reader to the FY 2020 IPPS/LTCH PPS final rule (84 FR 
42288 through 42292) for additional discussion of the evaluation of 
substantial clinical improvement for purposes of new technology add-on 
payments under the IPPS.
    We note, consistent with the discussion in the FY 2003 IPPS final 
rule (67 FR 50015), that while FDA has regulatory responsibility for 
decisions related to marketing authorization (for example, approval, 
clearance, etc.), we do not rely upon FDA criteria in our evaluation of 
substantial clinical improvement for purposes of determining what 
services and technologies qualify for new technology add-on payments 
under Medicare. This criterion does not depend on the standard of 
safety and effectiveness on which FDA relies but on a demonstration of 
substantial clinical improvement in the Medicare population.
b. Alternative Inpatient New Technology Add-On Payment Pathway
    Beginning with applications for FY 2021 new technology add-on 
payments, under the regulations at Sec.  412.87(c), a medical device 
that is part of FDA's Breakthrough Devices Program may qualify for the 
new technology add-on payment under an alternative pathway. 
Additionally, under the regulations at Sec.  412.87(d) for certain 
antimicrobial products, beginning with FY 2021, a drug that is 
designated by FDA as a Qualified Infectious Disease Product (QIDP), 
and, beginning with FY 2022, a drug that is approved by FDA under the 
Limited Population Pathway for Antibacterial and Antifungal Drugs 
(LPAD), may also qualify for the new technology add-on payment under an 
alternative pathway. We refer the reader to the FY 2020 IPPS/LTCH PPS 
final rule (84 FR 42292 through 42297) and the FY 2021 IPPS/LTCH PPS 
final rule (85 FR 58737 through 58739) for further discussion on this 
policy. We note that CMS reviews the application based on the 
information provided by the applicant only under the alternative 
pathway specified by the applicant at the time of application 
submission. To receive approval for the new technology add-on payment 
under that alternative pathway, the technology must have the applicable 
FDA designation and meet all other requirements in the regulations in 
Sec.  412.87(c) and (d), as applicable.
(1) Alternative Pathway for Certain Transformative New Devices
    For applications received for new technology add-on payments for FY 
2021 and subsequent fiscal years, a medical device designated under 
FDA's Breakthrough Devices Program that has received FDA marketing 
authorization will be considered not substantially similar to an 
existing technology for purposes of the new technology add-on payment 
under the IPPS, and will not need to meet the requirement under Sec.  
412.87(b)(1) that it represent an advance that substantially improves, 
relative to technologies previously available, the diagnosis or 
treatment of Medicare beneficiaries. Under this alternative pathway, a 
medical device that has received FDA marketing authorization (that is, 
has been approved or cleared by, or had a De Novo classification 
request granted by, FDA) as a Breakthrough Device, for the indication 
covered by the Breakthrough Device designation, will need to meet the 
requirements of Sec.  412.87(c). We note that in the FY 2021 IPPS/LTCH 
PPS final rule (85 FR 58734 through 58736), we clarified our policy 
that a new medical device under this alternative pathway must receive 
marketing authorization for the indication covered by the Breakthrough 
Devices Program designation. We refer the reader to the FY 2021 IPPS/
LTCH PPS final rule (85 FR 58734 through 58736) for further discussion 
regarding this clarification.
(2) Alternative Pathway for Certain Antimicrobial Products
    For applications received for new technology add-on payments for 
certain antimicrobial products, beginning with FY 2021, if a technology 
is designated by FDA as a QIDP and received FDA marketing 
authorization, and, beginning with FY 2022, if a drug is approved under 
FDA's LPAD pathway and used for the indication approved under the LPAD 
pathway, it will be considered not substantially similar to an existing 
technology for purposes of new technology add-on payments and will not 
need to meet the requirement that it represent an advance that 
substantially improves, relative to technologies previously available, 
the diagnosis or treatment of Medicare beneficiaries. Under this 
alternative pathway for QIDPs and LPADs, a medical product that has 
received FDA marketing authorization and is designated by FDA as a QIDP 
or approved under the LPAD pathway will need to meet the requirements 
of Sec.  412.87(d). We refer the reader to the FY 2020 IPPS/LTCH PPS 
final rule (84 FR 42292 through 42297) and FY 2021 IPPS/LTCH PPS final 
rule (85 FR 58737 through 58739) for further discussion on this policy.
    We note that, in the FY 2021 IPPS/LTCH PPS final rule (85 FR 58737 
through 58739), we clarified that a new medical product seeking 
approval for the new technology add-on payment under the alternative 
pathway for QIDPs must receive FDA marketing authorization for the 
indication covered by the QIDP designation. We also finalized our 
policy to expand our alternative new technology add-on payment pathway 
for certain antimicrobial products to include products approved under 
the LPAD pathway and used for the indication approved under the LPAD 
pathway.
c. Additional Payment for New Medical Service or Technology
    The new medical service or technology add-on payment policy under 
the IPPS provides additional payments for cases with relatively high 
costs involving eligible new medical services or technologies, while 
preserving some of the incentives inherent under an average-based 
prospective payment system. The

[[Page 36025]]

payment mechanism is based on the cost to hospitals for the new medical 
service or technology. As noted previously, we do not include capital 
costs in the add-on payments for a new medical service or technology or 
make new technology add-on payments under the IPPS for capital-related 
costs (72 FR 47307 through 47308).
    For discharges occurring before October 1, 2019, under Sec.  
412.88, if the costs of the discharge (determined by applying operating 
cost-to-charge ratios (CCRs) as described in Sec.  412.84(h)) exceed 
the full DRG payment (including payments for IME and DSH, but excluding 
outlier payments), CMS made an add-on payment equal to the lesser of: 
(1) 50 percent of the costs of the new medical service or technology; 
or (2) 50 percent of the amount by which the costs of the case exceed 
the standard DRG payment.
    Beginning with discharges on or after October 1, 2019, for the 
reasons discussed in the FY 2020 IPPS/LTCH PPS final rule (84 FR 42297 
through 42300), we finalized an increase in the new technology add-on 
payment percentage, as reflected at Sec.  412.88(a)(2)(ii). 
Specifically, for a new technology other than a medical product 
designated by FDA as a QIDP, beginning with discharges on or after 
October 1, 2019, if the costs of a discharge involving a new technology 
(determined by applying CCRs as described in Sec.  412.84(h)) exceed 
the full DRG payment (including payments for IME and DSH, but excluding 
outlier payments), Medicare will make an add-on payment equal to the 
lesser of: (1) 65 percent of the costs of the new medical service or 
technology; or (2) 65 percent of the amount by which the costs of the 
case exceed the standard DRG payment. For a new technology that is a 
medical product designated by FDA as a QIDP, beginning with discharges 
on or after October 1, 2019, if the costs of a discharge involving a 
new technology (determined by applying CCRs as described in Sec.  
412.84(h)) exceed the full DRG payment (including payments for IME and 
DSH, but excluding outlier payments), Medicare will make an add-on 
payment equal to the lesser of: (1) 75 percent of the costs of the new 
medical service or technology; or (2) 75 percent of the amount by which 
the costs of the case exceed the standard DRG payment. For a new 
technology that is a medical product approved under FDA's LPAD pathway, 
beginning with discharges on or after October 1, 2020, if the costs of 
a discharge involving a new technology (determined by applying CCRs as 
described in Sec.  412.84(h)) exceed the full DRG payment (including 
payments for IME and DSH, but excluding outlier payments), Medicare 
will make an add-on payment equal to the lesser of: (1) 75 percent of 
the costs of the new medical service or technology; or (2) 75 percent 
of the amount by which the costs of the case exceed the standard DRG 
payment. As set forth in Sec.  412.88(b)(2), unless the discharge 
qualifies for an outlier payment, the additional Medicare payment will 
be limited to the full MS-DRG payment plus 65 percent (or 75 percent 
for certain antimicrobial products (QIDPs and LPADs)) of the estimated 
costs of the new technology or medical service. We refer the reader to 
the FY 2020 IPPS/LTCH PPS final rule (84 FR 42297 through 42300) for 
further discussion on the increase in the new technology add-on payment 
beginning with discharges on or after October 1, 2019.
    We note that, consistent with the prospective nature of the IPPS, 
we finalize the new technology add on payment amount for technologies 
approved or conditionally approved for new technology add-on payments 
in the final rule for each fiscal year and do not make mid-year changes 
to new technology add-on payment amounts. Updated cost information may 
be submitted and included in rulemaking to be considered for the 
following fiscal year.
    Section 503(d)(2) of the MMA (Pub. L. 108-173) provides that there 
shall be no reduction or adjustment in aggregate payments under the 
IPPS due to add-on payments for new medical services and technologies. 
Therefore, in accordance with section 503(d)(2) of the MMA, add-on 
payments for new medical services or technologies for FY 2005 and 
subsequent years have not been subjected to budget neutrality.
d. Evaluation of Eligibility Criteria for New Medical Service or 
Technology Applications
    In the FY 2009 IPPS final rule (73 FR 48561 through 48563), we 
modified our regulation at Sec.  412.87 to codify our longstanding 
practice of how CMS evaluates the eligibility criteria for new medical 
service or technology add-on payment applications. That is, we first 
determine whether a medical service or technology meets the newness 
criterion, and only if so, do we then make a determination as to 
whether the technology meets the cost threshold and represents a 
substantial clinical improvement over existing medical services or 
technologies. We specified that all applicants for new technology add-
on payments must have FDA approval or clearance by July 1 of the year 
prior to the beginning of the fiscal year for which the application is 
being considered. In the FY 2021 IPPS/LTCH PPS final rule, to more 
precisely describe the various types of FDA approvals, clearances and 
classifications that we consider under our new technology add-on 
payment policy, we finalized a technical clarification to the 
regulation to indicate that new technologies must receive FDA marketing 
authorization (such as pre-market approval (PMA); 510(k) clearance; the 
granting of a De Novo classification request, or approval of a New Drug 
Application (NDA)) by July 1 of the year prior to the beginning of the 
fiscal year for which the application is being considered. Consistent 
with our longstanding policy, we consider FDA marketing authorization 
as representing that a product has received FDA approval or clearance 
when considering eligibility for the new technology add-on payment (85 
FR 58742).
    Additionally, in the FY 2021 IPPS/LTCH PPS final rule (85 FR 58739 
through 58742), we finalized our proposal to provide conditional 
approval for new technology add-on payment for a technology for which 
an application is submitted under the alternative pathway for certain 
antimicrobial products at Sec.  412.87(d) that does not receive FDA 
marketing authorization by July 1 prior to the particular fiscal year 
for which the applicant applied for new technology add-on payments, 
provided that the technology otherwise meets the applicable add-on 
payment criteria. Under this policy, cases involving eligible 
antimicrobial products would begin receiving the new technology add-on 
payment sooner, effective for discharges the quarter after the date of 
FDA marketing authorization, provided that the technology receives FDA 
marketing authorization before July 1 of the fiscal year for which the 
applicant applied for new technology add-on payments.
    In the FY 2024 IPPS/LTCH PPS final rule (88 FR 58948 through 
58958), we finalized that, beginning with the new technology add-on 
payment applications for FY 2025, for technologies that are not already 
FDA market authorized for the indication that is the subject of the new 
technology add-on payment application, applicants must have a complete 
and active FDA market authorization request at the time of new 
technology add-on payment application submission and must provide 
documentation of FDA acceptance or filing to CMS at the time of 
application submission, consistent with the type of FDA marketing 
authorization application the applicant

[[Page 36026]]

has submitted to FDA. See Sec.  412.87(e) and further discussion in the 
FY 2024 IPPS/LTCH PPS final rule (88 FR 58948 through 58958). We also 
finalized that, beginning with FY 2025 applications, in order to be 
eligible for consideration for the new technology add-on payment for 
the upcoming fiscal year, an applicant for new technology add-on 
payments must have received FDA approval or clearance by May 1 (rather 
than July 1) of the year prior to the beginning of the fiscal year for 
which the application is being considered (except for an application 
that is submitted under the alternative pathway for certain 
antimicrobial products), as reflected at Sec. Sec.  412.87(f)(2) and 
(f)(3), as amended and redesignated in the FY 2024 IPPS/LTCH PPS final 
rule (88 FR 58948 through 58958, 88 FR 59331).
e. New Technology Liaisons
    Many interested parties (including device/biologic/drug developers 
or manufacturers, industry consultants, others) engage CMS for 
coverage, coding, and payment questions or concerns. In order to 
streamline engagement by centralizing the different innovation pathways 
within CMS including new technology add-on payments, CMS has 
established a team of new technology liaisons that can serve as an 
initial resource for interested parties. This team is available to 
assist with all of the following:
     Help to point interested parties to or provide information 
and resources where possible regarding process, requirements, and 
timelines.
     Coordinate and facilitate opportunities for interested 
parties to engage with various CMS components.
     Serve as a primary point of contact for interested parties 
and provide updates on developments where possible or appropriate.
    We receive many questions from parties interested in pursuing new 
technology add-on payments who may not be entirely familiar with 
working with CMS. While we encourage interested parties to first review 
our resources available at https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/newtech, we know that there may 
be additional questions about the application process. Interested 
parties with further questions regarding Medicare's coverage, coding, 
and payment processes, and how they can navigate these processes, 
whether for new technology add-on payments or otherwise, should review 
the updated resource guide available at: https://www.cms.gov/medicare/coding-billing/guide-medical-technology-companies-other-interested-parties. Parties that would like to further discuss questions or 
concerns with CMS should contact the new technology liaison team at 
[email protected].
f. Application Information for New Medical Services or Technologies
    Applicants for add-on payments for new medical services or 
technologies for FY 2026 must submit a formal request, including a full 
description of the clinical applications of the medical service or 
technology and the results of any clinical evaluations demonstrating 
that the new medical service or technology represents a substantial 
clinical improvement (unless the application is under one of the 
alternative pathways as previously described), along with a significant 
sample of data to demonstrate that the medical service or technology 
meets the high-cost threshold. CMS will review the application based on 
the information provided by the applicant under the pathway specified 
by the applicant at the time of application submission. Complete 
application information, along with final deadlines for submitting a 
full application, will be posted as it becomes available on the CMS 
website at: https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/newtech.html.
    To allow interested parties to identify the new medical services or 
technologies under review before the publication of the proposed rule 
for FY 2026, once the application deadline has closed, CMS will post on 
its website a list of the applications submitted, along with a brief 
description of each technology as provided by the applicant.
    As discussed in the FY 2023 IPPS/LTCH PPS final rule (87 FR 48986 
through 48990), we finalized our proposal to publicly post online new 
technology add-on payment applications, including the completed 
application forms, certain related materials, and any additional 
updated application information submitted subsequent to the initial 
application submission (except certain volume, cost and other 
information identified by the applicant as confidential), beginning 
with the application cycle for FY 2024, at the time the proposed rule 
is published. We also finalized that with the exception of information 
included in a confidential information section of the application, cost 
and volume information, and materials identified by the applicant as 
copyrighted and/or not otherwise releasable to the public, the contents 
of the application and related materials may be posted publicly, and 
that we will not post applications that are withdrawn prior to 
publication of the proposed rule. We refer the reader to the FY 2023 
IPPS/LTCH PPS final rule (87 FR 48986 through 48990) for further 
information regarding this policy.
    We note that the burden associated with this information collection 
requirement is the time and effort required to collect and submit the 
data in the formal request for add-on payments for new medical services 
and technologies to CMS. The aforementioned burden is subject to the 
PRA and approved under OMB control number 0938-1347 and has an 
expiration date of December 31, 2026.
2. Public Input Before Publication of a Notice of Proposed Rulemaking 
on Add-On Payments
    Section 1886(d)(5)(K)(viii) of the Act, as amended by section 
503(b)(2) of the MMA, provides for a mechanism for public input before 
publication of a notice of proposed rulemaking regarding whether a 
medical service or technology represents a substantial clinical 
improvement. The process for evaluating new medical service and 
technology applications requires the Secretary to do all of the 
following:
     Provide, before publication of a proposed rule, for public 
input regarding whether a new service or technology represents an 
advance in medical technology that substantially improves the diagnosis 
or treatment of Medicare beneficiaries.
     Make public and periodically update a list of the services 
and technologies for which applications for add-on payments are 
pending.
     Accept comments, recommendations, and data from the public 
regarding whether a service or technology represents a substantial 
clinical improvement.
     Provide, before publication of a proposed rule, for a 
meeting at which organizations representing hospitals, physicians, 
manufacturers, and any other interested party may present comments, 
recommendations, and data regarding whether a new medical service or 
technology represents a substantial clinical improvement to the 
clinical staff of CMS.
    In order to provide an opportunity for public input regarding add-
on payments for new medical services and technologies for FY 2025 prior 
to publication of the FY 2025 IPPS/LTCH PPS proposed rule, we published 
a notice in the Federal Register on September 28, 2023 (88 FR 66850) 
and held a virtual town hall meeting on

[[Page 36027]]

December 13, 2023. In the announcement notice for the meeting, we 
stated that the opinions and presentations provided during the meeting 
would assist us in our evaluations of applications by allowing public 
discussion of the substantial clinical improvement criterion for the FY 
2025 new medical service and technology add-on payment applications 
before the publication of the FY 2025 IPPS/LTCH IPPS proposed rule.
    Approximately 130 individuals registered to attend the virtual town 
hall meeting. We posted the recordings of the virtual town hall on the 
CMS web page at: https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/AcuteInpatientPPS/newtech. We considered each applicant's 
presentation made at the town hall meeting, as well as written comments 
received by the December 18, 2023 deadline, in our evaluation of the 
new technology add-on payment applications for FY 2025 in the 
development of the FY 2025 IPPS/LTCH PPS proposed rule. In response to 
the published notice and the December 13, 2023 New Technology Town Hall 
meeting, we received written comments regarding the applications for FY 
2025 new technology add-on payments. As explained earlier and in the 
Federal Register notice announcing the New Technology Town Hall meeting 
(88 FR 66850 through 66853), the purpose of the meeting was 
specifically to discuss the substantial clinical improvement criterion 
with regard to pending new technology add-on payment applications for 
FY 2025. Therefore, we are not summarizing any written comments in this 
proposed rule that are unrelated to the substantial clinical 
improvement criterion. In section II.E.5. of the preamble of the 
proposed rule, we are summarizing comments regarding individual 
applications, or, if applicable, indicating that there were no comments 
received in response to the New Technology Town Hall meeting notice or 
New Technology Town Hall meeting, at the end of each discussion of the 
individual applications.
3. ICD-10-PCS Section ``X'' Codes for Certain New Medical Services and 
Technologies
    As discussed in the FY 2016 IPPS/LTCH PPS final rule (80 FR 49434), 
the ICD-10-PCS includes a new section containing the new Section ``X'' 
codes, which began being used with discharges occurring on or after 
October 1, 2015. Decisions regarding changes to ICD-10-PCS Section 
``X'' codes will be handled in the same manner as the decisions for all 
of the other ICD-10-PCS code changes. That is, proposals to create, 
delete, or revise Section ``X'' codes under the ICD-10-PCS structure 
will be referred to the ICD-10 Coordination and Maintenance Committee. 
In addition, several of the new medical services and technologies that 
have been, or may be, approved for new technology add-on payments may 
now, and in the future, be assigned a Section ``X'' code within the 
structure of the ICD-10-PCS. We posted ICD-10-PCS Guidelines on the CMS 
website at: https://www.cms.gov/Medicare/Coding/ICD10, including 
guidelines for ICD-10-PCS Section ``X'' codes. We encourage providers 
to view the material provided on ICD-10-PCS Section ``X'' codes.
4. Proposed FY 2025 Status of Technologies Receiving New Technology 
Add-On Payments for FY 2024
    In this section of the proposed rule, we discuss the proposed FY 
2025 status of 31 technologies approved for FY 2024 new technology add-
on payments, as set forth in the tables that follow. Specifically, we 
present our proposals to continue the new technology add-on payments 
for FY 2025 for those technologies that were approved for the new 
technology add-on payment for FY 2024, and which would still be 
considered ``new'' for purposes of new technology add-on payments for 
FY 2025. We also present our proposals to discontinue new technology 
add-on payments for FY 2025 for those technologies that were approved 
for the new technology add-on payment for FY 2024, and which would no 
longer be considered ``new'' for purposes of new technology add-on 
payments for FY 2025.
    Additionally, we note that we conditionally approved 
DefenCathTM (taurolidine/heparin) for FY 2024 new technology 
add-on payments under the alternative pathway for certain antimicrobial 
products (88 FR 58942 through 58944), subject to the technology 
receiving FDA marketing authorization by July 1, 2024. 
DefenCathTM (taurolidine/heparin) received FDA marketing 
authorization on November 15, 2023, and was eligible to receive new 
technology add-on payments in FY 2024 beginning with discharges on or 
after January 1, 2024. As DefenCathTM (taurolidine/heparin) 
received FDA marketing authorization prior to July 1, 2024, and was 
approved for new technology add-on payments in FY 2024, we are 
proposing to continue making new technology add-on payments for 
taurolidine/heparin for FY 2025.
    Our policy is that a medical service or technology may continue to 
be considered ``new'' for purposes of new technology add-on payments 
within 2 or 3 years after the point at which data begin to become 
available reflecting the inpatient hospital code assigned to the new 
service or technology. Our practice has been to begin and end new 
technology add-on payments on the basis of a fiscal year, and we have 
generally followed a guideline that uses a 6-month window before and 
after the start of the fiscal year to determine whether to extend the 
new technology add-on payment for an additional fiscal year. In 
general, we extend new technology add-on payments for an additional 
year only if the 3-year anniversary date of the product's entry onto 
the U.S. market occurs in the latter half of the fiscal year (70 FR 
47362).
    Table II.E.--01 lists the technologies for which we are proposing 
to continue making new technology add-on payments for FY 2025 because 
they are still considered ``new'' for purposes of new technology add-on 
payments. This table also presents the newness start date, new 
technology add-on payment start date, 3-year anniversary date of the 
product's entry onto the U.S. market, relevant final rule citations 
from prior fiscal years, proposed maximum add-on payment amount, and 
coding assignments for each technology. We refer readers to the cited 
final rules in the following table for a complete discussion of the new 
technology add-on payment application, coding, and payment amount for 
these technologies, including the applicable indications and discussion 
of the newness start date.
    We are inviting public comments on our proposals to continue new 
technology add-on payments for FY 2025 for the technologies listed in 
the following table.

6. Proposed FY 2025 Applications for New Technology Add-On Payments 
(Traditional Pathway)
    As discussed previously, in the FY 2023 IPPS/LTCH PPS final rule, 
we finalized our policy to publicly post online applications for new 
technology add-on payment beginning with FY 2024 applications (87 FR 
48986 through 48990). As noted in the FY 2023 IPPS/LTCH PPS final rule, 
we are continuing to summarize each application in this proposed rule. 
However, while we are continuing to provide discussion of the concerns 
or issues we identified with respect to applications submitted under 
the traditional pathway, we are providing more succinct information as 
part of the summaries in the proposed and final rules regarding the 
applicant's assertions as to how the medical service or technology 
meets the newness, cost, and substantial clinical improvement criteria. 
We refer readers to https://mearis.cms.gov/public/publications/ntap for 
the publicly posted FY 2025 new technology add-on payment applications 
and supporting information (with the exception of certain cost and 
volume information, and information or materials identified by the 
applicant as confidential or copyrighted), including tables listing the 
ICD-10-CM codes, ICD-10-PCS codes, and/or MS-DRGs related to the 
analyses of the cost criterion for certain technologies for the FY 2025 
new technology add-on payment applications.
    We received 16 applications for new technology add-on payments for 
FY 2025 under the new technology add-on payment traditional pathway. As 
discussed previously, in the FY 2024 IPPS/LTCH PPS final rule (88 FR 
58948 through 58958), we finalized that beginning with the new 
technology add-on payment applications for FY 2025, for technologies 
that are not already FDA market authorized for the indication that is 
the subject of the new technology add-on payment application, 
applicants must have a complete and active FDA market authorization 
request at the time of new technology add-on payment application 
submission and must provide documentation of FDA acceptance or filing 
to CMS at the time of application submission, consistent with the type 
of FDA marketing authorization application the applicant has submitted 
to FDA. See Sec.  412.87(e) and further discussion in the FY 2024 IPPS/
LTCH PPS final rule (88 FR 58948 through 58958). Of the 16 applications 
received under the traditional pathway, one applicant was not eligible 
for consideration for new technology add-on payment because it did not 
meet these requirements, and three applicants withdrew their 
application prior to the issuance of this proposed rule. In accordance 
with the regulations under Sec.  412.87(f), applicants for FY 2025 new 
technology add-on payments must have received FDA approval or clearance 
by May 1 of the year prior to the beginning of the fiscal year for 
which the application is being considered. We are addressing the 
remaining 12 applications. We note that the manufacturer for 
Casgevy\TM\ (exagamglogene autotemcel) submitted a single application, 
but for two separate indications, each of which is discussed separately 
in this section.
a. CASGEVYTM (exagamglogene autotemcel) First Indication: 
Sickle Cell Disease (SCD)
    Vertex Pharmaceuticals, Inc. submitted an application for new 
technology add-on payments for Casgevy\TM\ for FY 2025 for use in 
sickle cell disease. According to the applicant, Casgevy\TM\ is a one-
time, clustered regularly interspaced short palindromic repeats 
(CRISPR)/CRISPR-associated protein 9 (Cas9) modified autologous cluster 
of differentiation (CD)34+ hematopoietic stem & progenitor cell (HSPC) 
cellular therapy approved for the treatment of sickle cell disease 
(SCD) in patients 12 years and older with recurrent vaso-occlusive 
crises (VOC). Per the applicant, using a CRISPR/Cas9 gene editing 
technique, the patient's CD34+ HSPCs are edited ex vivo via Cas9, a 
nuclease enzyme that uses a highly specific guide ribonucleic acid 
(gRNA), at the critical transcription factor binding site GATA1 in the 
erythroid specific enhancer region of the B-cell lymphoma/leukemia 11A 
(BCL11A) gene. According to the applicant, as a result of the editing, 
GATA1 binding is irreversibly disrupted, and BCL11A expression is 
reduced, resulting in an increased production of fetal hemoglobin 
(HbF), and recapitulating a naturally occurring, clinically benign 
condition called hereditary persistence of fetal hemoglobin (HPFH) that 
reduces or eliminates SCD symptoms. As stated by the applicant, 
Casgevy\TM\ infusion induces increased HbF production in SCD patients 
to >=20 percent, which is known to be associated with fewer SCD 
complications via addressing the underlying cause of SCD by preventing 
RBC sickling. We note that the applicant is also seeking new technology 
add-on payments for Casgevy\TM\ for FY 2025 for use in treating 
transfusion-dependent beta thalassemia (TDT), as discussed separately 
later in this section.
    Please refer to the online application posting for Casgevy\TM\, 
available at https://mearis.cms.gov/public/publications/ntap/NTP2310171VPTU, for additional detail describing the technology and the 
disease treated by the technology.
    With respect to the newness criterion, according to the applicant, 
Casgevy\TM\ was granted Biologics License Application (BLA) approval 
from FDA on December 8, 2023, for treatment of SCD in patients 12 years 
of age or older with recurrent VOCs. According to the applicant, 
Casgevy\TM\ became commercially available immediately after FDA 
approval. Casgevy\TM\ is available in 20 mL vials containing 4 to 13 x 
10\6\ CD34+ cells/mL frozen in 1.5 to 20 mL of solution. The minimum 
dose is 3 x 10\6\ CD34+ cells per kg of body weight, which may be 
contained within multiple vials.
    Effective April 1, 2023, the following ICD-10-PCS codes may be used 
to uniquely describe procedures involving the use of Casgevy\TM\: 
XW133J8 (Transfusion of exagamglogene autotemcel into peripheral vein, 
percutaneous approach, new technology group 8) and XW143J8 (Transfusion 
of exagamglogene autotemcel into central vein, percutaneous approach, 
new technology group 8). The applicant provided a list of ICD-10-CM 
diagnosis codes that may be used to identify this indication for 
Casgevy\TM\. Please refer to the online application posting for the 
complete list of ICD-10-CM codes provided by the applicant. We believe 
the relevant ICD-10-CM codes to identify the indication of SCD would 
be: D57.1 (Sickle-cell disease without crisis), D57.20 (Sickle-cell/Hb-
C disease without crisis), D57.40 (Sickle-cell thalassemia without 
crisis), D57.42 (Sickle-cell thalassemia beta zero without crisis), 
D57.44 (Sickle-cell thalassemia beta plus without crisis), or D57.80 
(Other sickle-cell disorders without crisis). We are inviting public 
comments on the use of these ICD-10-CM diagnosis codes to identify the 
indication of SCD for purposes of the new technology add-on payment, if 
approved.
    As previously discussed, if a technology meets all three of the 
substantial similarity criteria under the newness criterion, it would 
be considered substantially similar to an existing technology and would 
not be considered ``new'' for the purpose of new technology add-on 
payments.
    With respect to the substantial similarity criteria, the applicant 
asserted that Casgevy\TM\ is not substantially similar to other 
currently available technologies, because Casgevy\TM\ is the

[[Page 36032]]

first approved therapy to use CRISPR gene editing technology and no 
other approved technology uses the same or a similar mechanism of 
action; and therefore, the technology meets the newness criterion. The 
following table summarizes the applicant's assertions regarding the 
substantial similarity criteria. Please see the online application 
posting for Casgevy\TM\ for the applicant's complete statements in 
support of its assertion that Casgevy\TM\ is not substantially similar 
to other currently available technologies.
[GRAPHIC] [TIFF OMITTED] TP02MY24.079

    We note that CasgevyTM may have the same or similar 
mechanism of action to LyfgeniaTM, for which we also 
received an application for new technology add-on payments for FY 2025. 
Casgevy\TM\ and Lyfgenia\TM\ are both gene therapies using modified 
autologous CD34+ hematopoietic stem and progenitor cell (HSPC) 
therapies administered via stem cell transplantation for the treatment 
of SCD. LyfgeniaTM was approved by FDA for this indication 
on December 8, 2023. We note that both technologies are autologous, ex-
vivo modified hematopoietic stem-cell biological products. For these 
technologies, patients are required to undergo CD34+ HSPC mobilization 
followed by apheresis to extract CD34+ HSPCs for manufacturing and then 
myeloablative conditioning using busulfan to deplete the patient's bone 
marrow in preparation for the technologies' modified stem cells to 
engraft to the bone marrow. Once engraftment occurs for both 
technologies, the patient's cells start to produce a different form of 
hemoglobin in order to reduce the sickling hemoglobin. Further, both 
technologies appear to map to the same MS-DRGs, MS-DRG 016 (Autologous 
Bone Marrow Transplant with CC/MCC) and 017 (Autologous Bone Marrow 
Transplant without CC/MCC), and to treat the same or similar disease 
(sickle cell disease) in the same or similar patient population 
(patients 12 years of age and older who have a history of vaso-
occlusive events). Accordingly, as it appears that CasgevyTM 
and LyfgeniaTM may use the same or similar mechanism of 
action to achieve a therapeutic outcome (that is, to reduce the amount 
of sickling hemoglobin to reduce and prevent VOEs associated with SCD), 
would be assigned to the same MS-DRG, and treat the same or similar 
patient population and disease, we believe that these technologies may 
be substantially similar to each other such that they should be 
considered as a single application for purposes of new technology add-
on payments. We note that if we determine that this technology is 
substantially similar to LyfgeniaTM, we believe the newness 
period would begin on December 8, 2023, the date both 
CasgevyTM and LyfgeniaTM received FDA approval 
for SCD. We are interested in information on how these two technologies 
may differ from each other with respect to the substantial similarity 
criteria and newness criterion, to inform our analysis of whether 
CasgevyTM and LyfgeniaTM are substantially 
similar to each other and therefore should be considered as a single 
application for purposes of new technology add-on payments.
    We are inviting public comments on whether CasgevyTM 
meets the newness criterion, including whether CasgevyTM is 
substantially similar to LyfgeniaTM and whether these 
technologies should be evaluated as a single technology for purposes of 
new technology add-on payments.
    With respect to the cost criterion, the applicant searched the FY 
2022 MedPAR and provided multiple analyses to demonstrate that 
Casgevy\TM\ meets the cost criterion. The applicant included two 
cohorts in the analyses to identify potential cases representing 
patients who may be eligible for Casgevy\TM\: the first cohort included 
all cases in MS-DRG 014 (Allogeneic Bone Marrow Transplant) to account 
for the low volume of SCD or transfusion-dependent beta thalassemia 
(TDT) cases,

[[Page 36033]]

and the second cohort included cases in MS-DRG 014 (Allogeneic Bone 
Marrow Transplant) with any ICD-10-CM diagnosis code of SCD or TDT. The 
applicant explained that the cost analyses for SCD and TDT were 
combined because the volume of cases with a sickle cell disease or beta 
thalassemia diagnosis code was very low, and because it believed both 
indications would be approved in time for new technology add-on 
payment. In addition, the applicant noted that when searching for cases 
in DRG 014 with SCD or beta thalassemia diagnosis codes, there were no 
beta thalassemia cases. The applicant noted that cases included in the 
analysis may not be a completely accurate representation of cases that 
will be eligible for Casgevy\TM\ but that the analyses were provided in 
recognition of the low volume of cases.
    The applicant performed two analyses for each cohort: one with all 
prior drug charges maintained, representing a scenario in which there 
is no change to patient drug regimen with the use of Casgevy\TM\; and 
the other with all prior drug charges removed, representing a scenario 
in which no ancillary drugs are used in the treatment of Casgevy\TM\ 
patients. Per the applicant, this was done because some patients 
receiving CasgevyTM could receive fewer ancillary drugs 
during the inpatient stay, but it was difficult to know with certainty 
whether this would be the case or to identify the exact differences in 
drug regimens between patients receiving CasgevyTM and those 
receiving allogeneic bone marrow transplants. The applicant noted the 
analyses with drug charges removed were likely an over-estimation of 
the ancillary drug charges that would be removed in cases involving the 
use of Casgevy\TM\, but these were provided as sensitivity analyses.
    According to the applicant, eligible cases for CasgevyTM 
will be mapped to either Pre-MDC MS-DRG 016 (Autologous Bone Marrow 
Transplant with CC/MCC) or Pre-MDC MS-DRG 017 (Autologous Bone Marrow 
Transplant without CC/MCC), depending on whether complications or 
comorbidities (CCs) or major complications or comorbidities (MCCs) are 
present. For each analysis, the applicant used the FY 2025 new 
technology add-on payment threshold for Pre-MDC MS-DRG 016 for all 
identified cases, because it was typically higher than the threshold 
for Pre-MDC MS-DRG 017. Each analysis followed the order of operations 
described in the table later in this section.
    For the first cohort, the applicant included all cases associated 
with MS-DRG 014 (Allogeneic Bone Marrow Transplant). The applicant used 
the inclusion/exclusion criteria described in the following table and 
identified 996 claims mapping to MS-DRG 014. With all prior drug 
charges maintained (Scenario 1), the applicant calculated a final 
inflated average case-weighted standardized charge per case of 
$12,325,062, which exceeded the average case-weighted threshold amount 
of $182,491. With all prior drug charges removed (Scenario 2), the 
applicant calculated a final inflated average case-weighted 
standardized charge per case of $12,181,526, which exceeded the average 
case-weighted threshold amount of $182,491.
    For the second cohort, the applicant searched for cases within MS-
DRG 014 (Allogeneic Bone Marrow Transplant) with any ICD-10-CM 
diagnosis codes representing SCD or TDT. The applicant used the 
inclusion/exclusion criteria described in the following table and 
identified 11 claims mapping to MS-DRG 014 (Allogeneic Bone Marrow 
Transplant). With all prior drug charges maintained (Scenario 3), the 
applicant calculated a final inflated average case-weighted 
standardized charge per case of $12,125,212, which exceeded the average 
case-weighted threshold amount of $182,491. With all prior drug charges 
removed (Scenario 4), the applicant calculated a final inflated average 
case-weighted standardized charge per case of $12,086,551, which 
exceeded the average case-weighted threshold amount of $182,491.
    Because the final inflated average case-weighted standardized 
charge per case exceeded the average case-weighted threshold amount in 
all scenarios, the applicant maintained that Casgevy\TM\ meets the cost 
criterion.

    We are inviting public comments on whether Casgevy\TM\ meets the 
cost criterion.

    \17\ Lists referenced here may be found in the cost criterion 
codes and MS-DRGs attachments included in the online posting for the 
technology.
---------------------------------------------------------------------------

    With regard to the substantial clinical improvement criterion, the 
applicant asserted that Casgevy\TM\ represents a substantial clinical 
improvement over existing technologies because it is anticipated to 
expand patient eligibility for potentially curative SCD therapies, have 
improved clinical outcomes relative to available therapies, and avoid 
certain serious risks or side effects associated with existing 
potentially curative treatment options for SCD. The applicant provided 
one study to support these claims, as well as eight background articles 
about clinical outcomes and safety risks of other SCD treatments.\18\ 
The following table summarizes the applicant's assertions regarding the 
substantial clinical improvement criterion. Please see the online 
posting for Casgevy\TM\ for the applicant's complete statements 
regarding the substantial clinical improvement criterion and the 
supporting evidence provided.

    After review of the information provided by the applicant, we have 
the following concerns regarding whether Casgevy\TM\ meets the 
substantial clinical improvement criterion. We note that the only 
assessment of the technology submitted was from conference 
presentations that provide data on the ongoing CLIMB-121 trial, a phase 
1/2/3 single-arm trial assessing a single dose of CasgevyTM 
in patients 12 to 35 years old with SCD and a history of 2 or more 
severe VOCs per year over 2 years. The most recent data presented at 
ASH in December 2023,\19\ which appears to supersede the earlier 
results from Locatelli et al. (2023),\20\ indicates 44 participants 
received CasgevyTM for SCD, of which only 30 participants 
were evaluable for the primary and key secondary endpoints because they 
were followed for at least 16 months (up to 45.5 months) post 
CasgevyTM infusion. The applicant stated 96.7% of patients 
achieved the primary efficacy endpoint (free of severe VOCs for at 
least 12 consecutive months) and 100% of patients achieved the key 
secondary efficacy endpoint (free from in-patient hospitalization for 
severe VOCs for at least 12 consecutive months). Additionally, the 
applicant noted a safety profile consistent with myeloablative busulfan 
and autologous HSCT and that there were no malignancies nor serious 
adverse events related to CasgevyTM. However, we note that 
the provided evidence did not include peer-reviewed literature that 
directly assessed the use of Casgevy\TM\ for SCD. We also question 
whether the small study population may limit the generalizability of 
these study outcomes to a Medicare population. In addition, from the 
evidence submitted, we were also unable to determine where the study 
took place (that is, within the U.S. or in locations outside the U.S), 
which may also limit generalizability to the Medicare population. 
Additionally, we question if the short follow-up duration is sufficient 
to assess improvements in long-term clinical outcomes.

    Furthermore, the applicant asserted that CasgevyTM 
significantly improves clinical outcomes relative to services or 
technologies previously available. Regarding the claim that 
CasgevyTM is the first gene therapy specifically approved 
for the treatment of SCD in patients 12 years and older with

[[Page 36036]]

recurrent VOCs, the applicant claims it was first to submit and have 
their BLA accepted for a genetic therapy for treatment of SCD. The 
applicant states the PDUFA date for CasgevyTM of December 8, 
2023, and the PDUFA data for another gene therapy for SCD is December 
20, 2023, and that Casgevy and another product were both approved on 
December 8, 2023, as the first gene therapies for SCD. However, while 
this claim was made in support of the assertion that 
CasgevyTM significantly improves clinical outcomes, we note 
that the information submitted regarding PDUFA dates and FDA approvals 
does not appear to provide data regarding a significantly improved 
clinical outcome under Sec.  412.87(b)(1)(ii)(C).
    With regards to the claim that CasgevyTM is expected to 
avoid certain serious risks or side effects associated with approved 
viral-based gene therapies for SCD, the applicant cites the potential 
risk of insertional oncogenesis after treatment with 
LyfgeniaTM per the package insert for this other gene 
therapy for SCD. We note that because clinical trials are conducted 
under widely varying conditions, we question whether adverse reaction 
rates observed in the clinical trials of one drug can be directly 
compared to rates in the clinical trials of another drug. We also 
question if the follow-up duration for patients treated with 
CasgevyTM is sufficient to assess improvement in the rate of 
malignancy.
    With regard to the claim that CasgevyTM is expected to 
avoid certain serious risks or side effects associated with existing 
potentially curative treatment options for SCD, the applicant states 
that there are significant risks associated with allo-HSCT, including 
graft failure (up to 9 percent frequency), acute and chronic graft-
versus-host disease (GVHD) (with chronic GVHD up to 18 percent 
frequency), severe infection, hematologic malignancy, bleeding events, 
and death. In contrast, the applicant claims CasgevyTM does 
not require an allogeneic donor as each patient is their own donor and 
therefore does not have risks of acute and chronic GVHD or immunologic 
risks of secondary graft failure/rejection, in addition to not 
requiring post-transplant immunosuppressive therapies. However, we 
would be interested in additional evidence regarding the frequency and 
clinical relevance of side effects such as severe infection, 
hematologic malignancy, bleeding events, and death for both therapies.
    We are inviting public comments on whether Casgevy\TM\ meets the 
substantial clinical improvement criterion.
    We did not receive any written comments in response to the New 
Technology Town Hall meeting notice published in the Federal Register 
regarding the substantial clinical improvement criterion for 
Casgevy\TM\.
b. Casgevy\TM\ (exagamglogene autotemcel) Second Indication: 
Transfusion-Dependent [beta]-Thalassemia (TDT)
    Vertex Pharmaceuticals, Inc. submitted an application for new 
technology add-on payments for Casgevy\TM\ for FY 2025 for TDT. 
According to the applicant, Casgevy\TM\ is a one-time, clustered 
regularly interspaced short palindromic repeats (CRISPR)/CRISPR-
associated protein 9 (Cas9) modified autologous cluster of 
differentiation (CD)34+ hematopoietic stem & progenitor cell (HSPC) 
cellular therapy indicated for the treatment of transfusion-dependent 
[beta]-thalassemia (TDT) in patients 12 years of age or older. Per the 
applicant, using a CRISPR/Cas9 gene editing technique, the patient's 
CD34+ HSPCs are edited ex vivo via Cas9, a nuclease enzyme that uses a 
highly specific guide ribonucleic acid (gRNA), at the critical 
transcription factor binding site GATA1 in the erythroid specific 
enhancer region of the B-cell lymphoma/leukemia 11A (BCL11A) gene. 
According to the applicant, as a result of the editing, GATA1 binding 
is irreversibly disrupted, and BCL11A expression is reduced, resulting 
in an increased production of fetal hemoglobin (HbF). As stated by the 
applicant, this increase in HbF recapitulates a naturally occurring, 
clinically benign condition called hereditary persistence of fetal 
hemoglobin (HPFH). The applicant states that as a result, Casgevy\TM\ 
infusion induces increased HbF production in TDT patients so that 
circulating red blood cells (RBC) exhibit nearly 100 percent HbF, 
eliminating the need for RBC transfusions. As previously discussed 
earlier in this section, the applicant is also seeking new technology 
add-on payments for Casgevy\TM\ for FY 2025 for use in treating SCD.
    Please refer to the online application posting for Casgevy\TM\, 
available at https://mearis.cms.gov/public/publications/ntap/NTP2310171VPTU, for additional detail describing the technology and the 
disease treated by the technology.
    With respect to the newness criterion, according to the applicant, 
Casgevy\TM\ was granted Biologics License Application (BLA) approval 
from FDA on January 16, 2024, for the treatment of TDT in patients 12 
years of age and older. The applicant also explained that the minimum 
dosage of Casgevy\TM\ is 3x10\6\ CD34 + cells per kg of patient's 
weight. A single dose of Casgevy\TM\ is supplied in one or more vials, 
with each vial containing 4 to 13x10\6\ cells/mL suspended in 1.5 to 20 
mL of cryo-preservative medium.
    Effective April 1, 2023, the following ICD-10-PCS codes may be used 
to uniquely describe procedures involving the use of Casgevy\TM\: 
XW133J8 (Transfusion of exagamglogene autotemcel into peripheral vein, 
percutaneous approach, new technology group 8) and XW143J8 (Transfusion 
of exagamglogene autotemcel into central vein, percutaneous approach, 
new technology group 8). The applicant provided a list of diagnosis 
codes that may be used to currently identify this indication for 
Casgevy\TM\ under the ICD-10-CM coding system. Please refer to the 
online application posting for the complete list of ICD-10-CM codes 
provided by the applicant. We believe the relevant ICD-10-CM codes to 
identify the indication of TDT would be: D56.1 (Beta thalassemia), 
D56.2 (Delta-beta thalassemia), or D56.5 (Hemoglobin E-beta 
thalassemia). We are inviting public comments on the use of these ICD-
10-CM diagnosis codes to identify the indication of TDT for purposes of 
the new technology add-on payment, if approved.
    As previously discussed, if a technology meets all three of the 
substantial similarity criteria under the newness criterion, it would 
be considered substantially similar to an existing technology and would 
not be considered ``new'' for the purpose of new technology add-on 
payments.
    With respect to the substantial similarity criteria, the applicant 
asserted that Casgevy\TM\ is not substantially similar to other 
currently available technologies because Casgevy\TM\ is the first 
approved therapy to use CRISPR gene editing as its mechanism of action, 
and therefore, the technology meets the newness criterion. The 
following table summarizes the applicant's assertions regarding the 
substantial similarity criteria. Please see the online application 
posting for Casgevy\TM\ for the applicant's complete statements in 
support of its assertion that Casgevy\TM\ is not substantially similar 
to other currently available technologies.

[[Page 36037]]

[GRAPHIC] [TIFF OMITTED] TP02MY24.082

    We question whether Casgevy\TM\ may be the same or similar to other 
gene therapies used to treat TDT, specifically Zynteglo\TM\, which was 
approved for treatment of TDT on August 17, 2022. Casgevy\TM\ and 
Zynteglo\TM\ are both gene therapies using modified autologous CD34+ 
HSPC therapies administered via stem cell transplantation for the 
treatment of TDT. Both technologies are autologous, ex-vivo modified 
hematopoietic stem-cell biological products. For these technologies, 
patients are required to undergo CD34+ HSPC mobilization followed by 
apheresis to extract CD34+ HSPCs for manufacturing and then 
myeloablative conditioning using busulfan to deplete the patient's bone 
marrow in preparation for the technologies' modified stem cells to 
engraft to the bone marrow. Once engraftment occurs, the patient's 
cells start to produce a different form of hemoglobin to increase total 
hemoglobin and reduce the need for RBC transfusions. Therefore, it 
appears as if Casgevy\TM\ and Zynteglo\TM\ would use a similar 
mechanism of action to achieve a therapeutic outcome for the treatment 
of TDT. Further, both technologies appear to map to the same MS-DRGs, 
MS-DRG 016 (Autologous Bone Marrow Transplant with CC/MCC) and 017 
(Autologous Bone Marrow Transplant without CC/MCC), and to treat the 
same or similar disease (beta thalassemia) in the same or similar 
patient population (patients who require regular blood transfusions). 
Accordingly, we believe that these technologies may be substantially 
similar to each other. We note that if Casgevy\TM\ is substantially 
similar to Zynteglo\TM\ for the treatment of TDT, we believe the 
newness period for this technology would begin on August 17, 2022, with 
the Biologics License Application (BLA) approval date for Zynteglo\TM\.
    We are inviting public comments on whether Casgevy\TM\ is 
substantially similar to existing technologies and whether Casgevy\TM\ 
meets the newness criterion.
    With respect to the cost criterion, the applicant searched the FY 
2022 MedPAR and provided multiple analyses to demonstrate that 
Casgevy\TM\ meets the cost criterion. The applicant included two 
cohorts in the analyses to identify potential cases representing 
patients who may be eligible for Casgevy\TM\: the first cohort included 
all cases in MS-DRG 014 (Allogeneic Bone Marrow Transplant) to account 
for the low volume of sickle cell disease (SCD) or TDT cases, and the 
second cohort included cases in MS-DRG 014 (Allogeneic Bone Marrow 
Transplant) with any ICD-10-CM diagnosis code of SCD or TDT. The 
applicant explained that the cost analyses for SCD and TDT were 
combined because the volume of cases with a sickle cell disease or beta 
thalassemia diagnosis code was very small, and because it believed both 
indications would be approved in time

[[Page 36038]]

for new technology add-on payment. In addition, the applicant noted 
that when searching for cases in DRG 014 with SCD or beta thalassemia 
diagnosis codes, there were no beta thalassemia cases. The applicant 
noted that cases included in the analysis may not be a completely 
accurate representation of cases that will be eligible for Casgevy\TM\ 
but that the analyses were provided in recognition of the low volume of 
cases.
    The applicant performed two analyses for each cohort: one with all 
prior drug charges maintained, representing a scenario in which there 
is no change to patient drug regimen with the use of Casgevy\TM\; and 
the other with all prior drug charges removed, representing a scenario 
in which no ancillary drugs are used in the treatment of Casgevy\TM\ 
patients. Per the applicant, this was done because some patients 
receiving CasgevyTM could receive fewer ancillary drugs 
during the inpatient stay, but it was difficult to know with certainty 
whether this would be the case or to identify the exact differences in 
drug regimens between patients receiving CasgevyTM and those 
receiving allogeneic bone marrow transplants. The applicant notes the 
analyses with drug charges removed were likely an over-estimation of 
the ancillary drug charges that would be removed in cases involving the 
use of Casgevy\TM\, but these were provided as sensitivity analyses.
    According to the applicant, eligible cases for CasgevyTM 
will be mapped to either Pre-MDC MS-DRG 016 (Autologous Bone Marrow 
Transplant with CC/MCC) or Pre-MDC MS-DRG 017 (Autologous Bone Marrow 
Transplant without CC/MCC), depending on whether complications or 
comorbidities (CCs) or major complications or comorbidities (MCCs) are 
present. For each analysis, the applicant used the FY 2025 new 
technology add-on payment threshold for Pre-MDC MS-DRG 016 for all 
identified cases, because it was typically higher than the threshold 
for Pre-MDC MS-DRG 017. Each analysis followed the order of operations 
described in the table later in this section.
    For the first cohort, the applicant included all cases associated 
with MS-DRG 014 (Allogeneic Bone Marrow Transplant). The applicant used 
the inclusion/exclusion criteria described in the following table and 
identified 996 claims mapping to MS-DRG 014. With all prior drug 
charges maintained (Scenario 1), the applicant calculated a final 
inflated average case-weighted standardized charge per case of 
$12,325,062, which exceeded the average case-weighted threshold amount 
of $182,491. With all prior drug charges removed (Scenario 2), the 
applicant calculated a final inflated average case-weighted 
standardized charge per case of $12,181,526, which exceeded the average 
case-weighted threshold amount of $182,491.
    For the second cohort, the applicant searched for cases within MS-
DRG 014 (Allogeneic Bone Marrow Transplant) with any ICD-10-CM 
diagnosis codes representing SCD or TDT. The applicant used the 
inclusion/exclusion criteria described in the following table and 
identified 11 claims mapping to MS-DRG 014 (Allogeneic Bone Marrow 
Transplant). With all prior drug charges maintained (Scenario 3), the 
applicant calculated a final inflated average case-weighted 
standardized charge per case of $12,125,212, which exceeded the average 
case-weighted threshold amount of $182,491. With all prior drug charges 
removed (Scenario 4), the applicant calculated a final inflated average 
case-weighted standardized charge per case of $12,086,551, which 
exceeded the average case-weighted threshold amount of $182,491.
    Because the final inflated average case-weighted standardized 
charge per case exceeded the average case-weighted threshold amount in 
all scenarios, the applicant asserted that Casgevy\TM\ meets the cost 
criterion.

    We are inviting public comments on whether Casgevy\TM\ meets the 
cost criterion.
    With regard to the substantial clinical improvement criterion, the 
applicant asserted that Casgevy\TM\ represents a substantial clinical 
improvement over existing technologies because it is expected to avoid 
certain serious risks or side effects associated with the existing 
approved gene therapy for TDT, Zynteglo\TM\. The applicant provided one 
study to support these claims, as well as two package inserts.\22\ The 
following table summarizes the applicant's assertion regarding the 
substantial clinical improvement criterion. Please see the online 
posting for Casgevy\TM\ for the applicant's complete statements 
regarding the substantial clinical improvement criterion and the 
supporting evidence provided.
---------------------------------------------------------------------------

    \22\ Background articles are not included in the following table 
but can be accessed via the online posting for the technology.
[GRAPHIC] [TIFF OMITTED] TP02MY24.084

    After review of the information provided by the applicant, we have 
the following concerns regarding whether Casgevy\TM\ meets the 
substantial clinical improvement criterion. We note that the provided 
evidence did not include any peer-reviewed literature that directly 
assessed the use of Casgevy\TM\ for TDT. We note that the only 
assessment of the technology submitted was from a conference 
presentation \23\ that provides data on the CLIMB-111 trial, an ongoing 
phase 1/2/3 single-arm trial assessing a single dose of 
CasgevyTM in patients 12 to 35 years old with TDT. The data 
submitted by the applicant indicated 48 participants aged 12 to 35 
years received CasgevyTM for TDT, of which only 27 
participants were evaluable for the primary and key secondary endpoints 
because they were followed for at least 16 months (up to 43.7 months) 
after CasgevyTM infusion. Per the applicant's conference 
presentation, 88.9% of participants achieved both the primary efficacy 
endpoint (transfusion independence for 12 consecutive months while 
maintaining a weighted average hemoglobin of at least 9 g/dL) and the 
key secondary efficacy endpoint (transfusion independence for 6 
consecutive months while maintaining a weighted average hemoglobin of 
at least 9 g/dL). The applicant noted that two patients had serious 
adverse events related to CasgevyTM. Due to the small study 
population and the median age of participants in the study, we question 
if these study outcomes would be generalizable to a Medicare 
population. In addition, from the evidence submitted, we were also 
unable to determine where the study took place (that is, within the 
U.S. or in locations outside the U.S), which may also limit 
generalizability to the Medicare population. We also question if the 
short follow-up duration is sufficient to assess improvements in long-
term clinical outcomes.

---------------------------------------------------------------------------

    Furthermore, with regard to the claim that CasgevyTM is 
expected to avoid certain serious risks or side effects associated with 
approved viral-based gene therapies for TDT, the applicant stated that 
Zynteglo\TM\ utilizes gene transfer to use a modified, inert lentivirus 
to add working exogenous copies of the [beta]-globin gene to increase 
functional hemoglobin A; due to this mechanism of action and the semi-
random nature of viral integration, the applicant stated that treatment 
with Zynteglo\TM\ carries the risk of lentiviral vector (LVV)-mediated 
insertional oncogenesis after treatment. The applicant explained that 
Casgevy\TM\ is an autologous ex-vivo modified hematopoietic stem-cell 
biological product which uses a non-viral mechanism of action (CRISPR/
Cas9 gene editing), and therefore, this technology does not carry a 
risk for insertional oncogenesis. The applicant also noted that gene 
editing approaches, including CRISPR/Cas9, have the potential to 
produce off-target edits, but in trials to date, off-target gene 
editing has not been observed in the edited CD34+ cells from healthy 
donors or patients. We note that we are unclear regarding the frequency 
and related clinical relevance of LVV-mediated oncogenesis. We also 
question if the follow-up duration for patients treated with 
CasgevyTM is sufficient to assess improvement in the rate of 
malignancy. We would be interested in more information on the overall 
safety profile comparison between Casgevy\TM\ and Zynteglo\TM\, as well 
as any comparisons of CasgevyTM to another potentially 
curative treatment, allogeneic hematopoietic stem cell transplant for 
patients with TDT.
    We are inviting public comments on whether Casgevy\TM\ meets the 
substantial clinical improvement criterion.
    We did not receive any written comments in response to the New 
Technology Town Hall meeting notice published in the Federal Register 
regarding the substantial clinical improvement criterion for 
Casgevy\TM\.
c. DuraGraft[supreg] (Vascular Conduit Solution)
    Marizyme, Inc. submitted an application for new technology add-on 
payments for DuraGraft[supreg] for FY 2025. According to the applicant, 
DuraGraft[supreg] is an intraoperative vein-graft preservation solution 
used during the harvesting and grafting interval during coronary artery 
bypass graft surgery (CABG). The applicant stated that the use of 
DuraGraft[supreg] does not change clinical/surgical practice; it 
replaces solutions currently used for flushing and storage of the 
saphenous vein grafts (SVG) from harvesting through grafting, including 
tests for graft leakage. As noted in the FY 2024 IPPS/LTCH PPS proposed 
rule (88 FR 26795), Somahlution, Inc., acquired by Marizyme in 
2020,\24\ submitted and

[[Page 36040]]

withdrew applications for new technology add-on payments for 
DuraGraft[supreg] for FY 2018 and FY 2019. The applicant also submitted 
an application for new technology add-on payments for FY 2020, as 
summarized in the FY 2020 IPPS/LTCH PPS proposed rule (84 FR 19305 
through 19312), that it withdrew prior to the issuance of the FY 2020 
IPPS/LTCH PPS final rule (84 FR 42180). We note that the applicant also 
submitted an application for new technology add-on payments for FY 
2024, as summarized in the FY 2024 IPPS/LTCH PPS proposed rule (88 FR 
26795 through 26803), that it withdrew prior to the issuance of the FY 
2024 IPPS/LTCH PPS final rule (88 FR 58804).

    Please refer to the online application posting for 
DuraGraft[supreg], available at https://mearis.cms.gov/public/publications/ntap/NTP231012EE9NW, for additional detail describing the 
technology and intraoperative ischemic injury.
    With respect to the newness criterion, according to the applicant, 
DuraGraft[supreg] was granted De Novo classification from FDA on 
October 4, 2023, for adult patients undergoing Coronary Artery Bypass 
Grafting surgeries and is intended for flushing and storage of SVGs 
from harvesting through grafting for up to 4 hours. Per the applicant, 
DuraGraft[supreg] is not yet commercially available due to a delay 
related to finalizing the label prior to manufacturing.
    The applicant stated that effective October 1, 2017, the following 
ICD-10-PCS code may be used to uniquely describe procedures involving 
the use of DuraGraft[supreg]: XY0VX83 (Extracorporeal introduction of 
endothelial damage inhibitor to vein graft, new technology group 3). 
Please refer to the online application posting for the complete list of 
ICD-10-CM and PCS codes provided by the applicant.
    As previously discussed, if a technology meets all three of the 
substantial similarity criteria under the newness criterion, it would 
be considered substantially similar to an existing technology and would 
not be considered ``new'' for the purpose of new technology add-on 
payments.
    With respect to the substantial similarity criteria, the applicant 
asserted that DuraGraft[supreg] is not substantially similar to other 
currently available technologies because DuraGraft[supreg] is a first-
in-class product as a storage and flushing solution for vascular grafts 
used during CABG surgery and the components of DuraGraft[supreg] 
directly interfere with the mechanisms of oxidative damage, and that 
therefore, the technology meets the newness criterion. The following 
table summarizes the applicant's assertions regarding the substantial 
similarity criteria. Please see the online application posting for 
DuraGraft[supreg] for the applicant's complete statements in support of 
its assertion that DuraGraft[supreg] is not substantially similar to 
other currently available technologies.
[GRAPHIC] [TIFF OMITTED] TP02MY24.085

    In the FY 2024 IPPS/LTCH PPS proposed rule (88 FR 26796), we 
expressed concern that the mechanism of action of DuraGraft[supreg] may 
be the same or similar to other vein graft storage solutions. 
Similarly, we note that according to the applicant, DuraGraft[supreg] 
prevents intraoperative ischemic injury to the endothelial layer of 
free vascular grafts, reducing the risks for post-CABG vein graft 
disease and graft failure, which are clinical manifestations of graft 
ischemia reperfusion injury (IRI), and we question whether 
DuraGraft[supreg] might have a similar mechanism of action as existing 
treatments for preventing ischemic injury of vein grafts during CABG 
surgery and reducing vein graft disease or its complications following 
CABG surgery. We are inviting public comments on whether 
DuraGraft[supreg] is substantially similar to existing technologies and 
whether DuraGraft[supreg] meets the newness criterion.
    With respect to the cost criterion, to identify potential cases 
representing patients who may be eligible for DuraGraft[supreg], the 
applicant searched the FY 2022 MedPAR file for cases reporting a 
combination of ICD-10-CM/PCS codes that represent patients who 
underwent CABG procedures. Please see the online posting for 
DuraGraft[supreg] for a complete list of MS-DRGs and ICD-10-CM and PCS 
codes provided by the applicant. Using the inclusion/exclusion criteria 
described in the following table, the applicant identified 33,511 cases 
mapping to 59 MS-DRGs, including MS-DRG 236 (Coronary Bypass Without 
Cardiac Catheterization Without MCC) representing 21.9 percent of the 
identified cases. The applicant followed the order of operations 
described in the following table and

[[Page 36041]]

calculated a final inflated average case-weighted standardized charge 
per case of $321,620, which exceeded the average case-weighted 
threshold amount of $235,829. Because the final inflated average case-
weighted standardized charge per case exceeded the average case-
weighted threshold amount, the applicant asserted that 
DuraGraft[supreg] meets the cost criterion.
[GRAPHIC] [TIFF OMITTED] TP02MY24.086

    We note the following concerns regarding the cost criterion. 
Although the applicant did not remove direct or indirect charges 
related to the prior technology, we note that the applicant indicated 
that the use of DuraGraft[supreg] replaces solutions currently used for 
flushing and storage of the SVGs harvested through grafting, including 
tests for graft leakage, in its discussion of the newness criterion. 
Therefore, we question whether the cost criterion analysis should 
remove charges for related or prior technologies, such as autologous 
heparinized blood (AHB), Plasmalyte/Normosol, Lactated Ringers, and 
heparinized saline (HS).

    We are inviting public comments on whether DuraGraft[supreg] meets 
the cost criterion.
    With regard to the substantial clinical improvement criterion, the 
applicant asserted that DuraGraft[supreg] represents a substantial 
clinical improvement over existing technologies because there is no 
other product or technology that reduces the incidence of peri-
operative myocardial infarction. The applicant provided four studies to 
support this assertion, as well as 47 background articles about 
reducing major adverse cardiac events (MACE).\26\ The following table

BILLING CODE 4120-01-C
    After review of the information provided by the applicant, we have 
the following concerns regarding whether DuraGraft[supreg] meets the 
substantial clinical improvement criterion. As discussed in the FY 2024 
IPPS/LTCH PPS proposed rule (88 FR 26800 through 26801), we expressed 
concern regarding the relatively small sample sizes of the Szalkiewicz 
et al. (2022) \27\ and Perrault et al. (2021) \28\ studies, as compared 
to the number of potentially eligible patients for this technology, and 
relatively short follow-up periods. We continue to question whether the 
sample was representative of the number of Medicare beneficiaries 
potentially eligible for DuraGraft[supreg]. We refer readers to the FY 
2024 IPPS/LTCH PPS proposed rule for further discussion of these 
concerns. For its FY 2025 application, the applicant also cited Lopez-
Menendez et al. (2021),\29\ which we note used a sample size of 180, 
and therefore we similarly question whether

[[Page 36043]]

the results of this study would be replicated with a larger patient 
sample.

    In the FY 2024 IPPS/LTCH proposed rule (88 FR 26800 through 26801), 
we also questioned whether the results from the Haime et al. (2018) 
\30\ study could be generalized to other patient groups, including 
nonveterans, women, or those from other racial or ethnic groups. We 
continue to question whether the demographic profiles in the Perrault, 
Szalkiewicz, and Haime studies that the applicant submitted were 
comparable with those of the U.S. Medicare patients who underwent CABG 
surgery. For its FY 2025 application, the applicant also cited the 
Lopez-Menendez et al. (2021) \31\ study, which was based on a European 
patient population that was predominantly male (82 percent to 90 
percent). However, as we noted in the FY 2024 IPPS/LTCH PPS proposed 
rule (88 FR 26800 through 26801), among the Medicare fee-for-service 
beneficiaries who underwent CABG surgery, male patients accounted for 
two-thirds (66 percent) of this population. Therefore, we continue to 
question whether the findings of these studies would be replicable 
among the Medicare population.

    We are inviting public comments on whether DuraGraft[supreg] meets 
the substantial clinical improvement criterion.
    In this section, we summarize and respond to written public 
comments received in response to the New Technology Town Hall meeting 
notice published in the Federal Register regarding the substantial 
clinical improvement criterion for DuraGraft[supreg].
    Comment: The applicant submitted a public comment in response to 
our question as to why two propensity match models were used in the 
propensity match comparison of the EU DuraGraft[supreg] Registry to the 
STS Registry that it presented during the New Technology Town Hall 
meeting. The applicant explained that the goal of propensity matching 
was to balance patient and technical factors predictive of mortality 
throughout the observation period and to correct for differences that 
may be encountered in the U.S. and Europe. The applicant stated that a 
primary propensity score model (PSM) with 35 variables (2,400 patients 
matched), and a secondary PSM with 25 variables (2,522 patients 
matched, sensitivity analysis) were used. The applicant noted that the 
propensity variables were chosen with a goal of comparing variables 
descriptive of (1) U.S. and Western European populations, (2) the 
general practice of cardiac surgery, and (3) standards of care for 
surgical technique. The applicant noted that an important set of 
variables that needed to be balanced were the components of the 
EuroScore II (ESII). ESII is comprised of 18 patient variables and, per 
the applicant, is considered to be the best predictor of peri-operative 
and early mortality. ESII variables relevant for shorter term mortality 
were supplemented with appropriate predictors for longer term 
mortality.32 33 34

---------------------------------------------------------------------------

    The applicant noted that the set of variables for the primary PSM 
included 35 characteristics that are most strongly associated with 
mortality across the time periods (including 1-year post-CABG) and were 
consistently observed to have the highest degree of impact in the 
studies. The applicant stated that these variables include 
demographics, cardiac and pre-op surgical risk factors, coronary 
anatomy, and surgical/procedural key characteristics (for example, 
grafting strategy and conduit selection) to serve as the primary 
analysis. The applicant indicated that all characteristics in the ESII 
are included in the risk factors, with the exception of endocarditis, 
surgery on the thoracic aorta, weight of the intervention, and poor 
mobility, as they are not relevant to the subset of patients being 
propensity matched, or in the case of poor mobility, not collected in 
both databases. The applicant stressed that this list was reviewed and 
edited with FDA during the pre-submission process. To further allow for 
the selection of a cohort matched for standard of care and surgical 
technique between the European and U.S. populations, additional 
relevant variables were added including pre-op cardiac risk, coronary 
anatomy, and surgical technique.
    The applicant further noted that the set of variables for the 
secondary PSM included 25 of the 35 variables from the primary PSM, 
excluding characteristics of pre-op cardiac risk factors, coronary 
anatomy, and aspects of surgical technique. The applicant asserted that 
the secondary PSM serves as a sensitivity analysis to estimate whether 
the standard of care for the treatment of patients with advanced 
coronary artery disease and surgical techniques differ for patients in 
the two cohorts which are otherwise balanced for surgical risk factors, 
and whether these differences could affect mortality outcomes.
    Response: We thank the applicant for its comments. We also note 
that the applicant has provided the baseline demographic 
characteristics and surgical risk factors of the two cohorts before and 
after propensity score matching, which appears to demonstrate that the 
two cohorts were more similar in those characteristics and factors as a 
result of propensity score matching. We will take this information into 
consideration when deciding whether to approve new technology add-on 
payments for DuraGraft[supreg].
d. ELREXFIOTM (elranatamab-bcmm)
    Pfizer, Inc. submitted an application for new technology add-on 
payments for ELREXFIOTM for FY 2025. According to the 
applicant, ELREXFIOTM is a B-cell maturation antigen (BCMA) 
directed cluster of differentiation (CD)3 T-cell engager indicated for 
the treatment of adult patients with relapsed or refractory multiple 
myeloma (RRMM) who have received at least four prior lines of therapy, 
including a proteasome inhibitor (PI), an immunomodulatory agent 
(IMiD), and an anti-CD38 monoclonal antibody (mAb). Per the applicant, 
ELREXFIOTM is a bispecific, humanized immunoglobulin 2-
alanine (IgG2[Delta]a) kappa antibody derived from two mAbs, 
administered as a fixed-dose, subcutaneous treatment. We note that the 
applicant submitted an application for new technology add-on payments 
for ELREXFIOTM for FY 2024 under the name elranatamab, as 
summarized in the FY 2024 IPPS/LTCH PPS proposed rule (88 FR 26803 
through 26809), but the technology did not meet the July 1, 2023 
deadline for FDA approval or clearance of the technology and,

[[Page 36044]]

therefore, was not eligible for consideration for new technology add-on 
payments for FY 2024 (88 FR 58804).
    Please refer to the online application posting for 
ELREXFIOTM available at https://mearis.cms.gov/public/publications/ntap/NTP2310176PV9B, for additional detail describing the 
technology and the disease treated by the technology.
    With respect to the newness criterion, according to the applicant, 
ELREXFIOTM was granted Biologics License Application (BLA) 
approval from FDA on August 14, 2023, for the treatment of adult 
patients with RRMM who have received at least four prior lines of 
therapy, including a PI, an IMiD, and an anti-CD38 mAb. According to 
the applicant, ELREXFIOTM was commercially available 
immediately after FDA approval. Per the applicant, the recommended 
doses of ELREXFIO\TM\ subcutaneous injection are step-up doses of 12 mg 
on day 1 and 32 mg on day 4, followed by a first treatment dose of 76 
mg on day 8 and subsequent treatment doses as indicated in the label. 
The applicant noted that treatment doses may be administered in an 
inpatient or outpatient setting. Per the applicant, patients should be 
hospitalized for 48 hours after administration of the first step-up 
dose, and for 24 hours after administration of the second step-up dose. 
The applicant assumed that there would be a single inpatient stay, with 
one 44 mg vial used per dose, resulting in two doses (each a step-up 
dose) being administered.
    The applicant stated that effective October 1, 2023, the following 
ICD-10-PCS code may be used to uniquely describe procedures involving 
the use of ELREXFIOTM: XW013L9 (Introduction of elranatamab 
antineoplastic into subcutaneous tissue, percutaneous approach, new 
technology group 9). The applicant stated that C90.00 (Multiple myeloma 
not having achieved remission), C90.01 (Multiple myeloma in remission), 
C90.02 (Multiple myeloma in relapse), and Z51.12 (Encounter for 
antineoplastic immunotherapy) may be used to currently identify the 
indication for ELREXFIOTM under the ICD-10-CM coding system.
    As previously discussed, if a technology meets all three of the 
substantial similarity criteria under the newness criterion, it would 
be considered substantially similar to an existing technology and would 
not be considered ``new'' for the purpose of new technology add-on 
payments.
    With respect to the substantial similarity criteria, the applicant 
asserted that ELREXFIOTM is not substantially similar to 
other currently available technologies because it is the only therapy 
approved for the treatment of patients with RRMM who have received 4 
prior lines of therapy including a PI, IMiD, and mAb that uses a 
humanized IgG2a antibody for the mechanism of action. Per the 
applicant, it is also the only BCMA-directed bispecific antibody (bsAb) 
therapy with clinical study data in its prescribing information 
supporting use in patients who have received prior BCMA-directed 
therapy, and that therefore, the technology meets the newness 
criterion. The following table summarizes the applicant's assertions 
regarding the substantial similarity criteria. Please see the online 
application posting for ELREXFIOTM for the applicant's 
complete statements in support of its assertion that 
ELREXFIOTM is not substantially similar to other currently 
available technologies.

BILLING CODE 4120-01-C
    With regard to the newness criterion, similar to our discussion in 
the FY 2024 IPPS/LTCH PPS proposed rule (88 FR 26804), we note that 
ELREXFIOTM may have a similar mechanism of action to that of 
TECVAYLI[supreg], for which we approved an application for new 
technology add-on payments for FY 2024 (88 FR 58891) for the treatment 
of adult patients with RRMM after four or more prior lines of therapy, 
including a PI, an IMiD, and an anti-CD38 mAb. As we previously noted, 
TECVAYLI[supreg]'s mechanism of action is described as a bsAb, with 
binding domains that simultaneously bind the BCMA target on tumor cells 
and the CD3 T-cell receptor (88 FR 58886). The applicant asserts that 
ELREXFIOTM has a unique CDR (the region of antibody that 
recognizes and binds to target epitopes) that is critical to the 
mechanism of action because it results in different targeted regions, 
impacting how the drug works to target the cancer cells. However, it is 
unclear how these differences result in a substantially different 
mechanism of action from TECVAYLI[supreg]. Because of the apparent 
similarity with the bsAb for ELREXFIOTM that uses binding 
domains that simultaneously bind the BCMA target on tumor cells and the 
CD3 T-cell receptor, we believe that the mechanism of action for 
ELREXFIOTM may be the same or similar to that of 
TECVAYLI[supreg]. The applicant also asserts that ELREXFIOTM 
is different from TECVAYLI[supreg] because the two are based on 
different immunoglobulin isotypes, and with the lower effector function 
of IgG2, ELREXFIOTM should only activate T-cells in the 
presence of BCMA and thus should only stimulate an immune response in 
the tumor. Based on our understanding, however, that this may relate to 
the risk of adverse event from ELREXFIOTM administration but 
is not critical to the way the drug treats the underlying disease, we 
question whether this would therefore relate to an assessment of 
substantial clinical improvement, rather than of substantial 
similarity.
    We also note that ELREXFIOTM and TECVAYLI[supreg] may 
treat the same or similar disease (RRMM) in the same or similar patient 
population (patients who have previously received a PI, IMiD, and an 
anti-CD38 mAb). The applicant claims ELREXFIOTM is different 
from TECVAYLI[supreg] because the prescribing information includes a 
new subpopulation, the patient population that had received prior BCMA-
directed therapy. However, we believe the lack of inclusion of this 
population in the prescribing information for TECVAYLI[supreg] does not 
necessarily exclude the use of TECVAYLI[supreg] in this patient 
population, nor does the FDA prescribing information for 
TECVAYLI[supreg] specifically exclude this patient population. As such, 
it is unclear whether ELREXFIOTM would in fact treat a 
patient population different from TECVAYLI[supreg]. Accordingly, as it 
appears that ELREXFIOTM and TECVAYLI[supreg] may use the 
same or similar mechanism of action to achieve a therapeutic outcome, 
would be assigned to the same MS-DRG, and treat the same or similar 
patient population and disease, we believe that these technologies may 
be substantially similar to each other. We note that if we determine 
that this technology is substantially similar to TECVAYLI[supreg], we 
believe the newness period for this technology would begin on November 
9, 2022, the date TECVAYLI[supreg] became commercially available.
    Furthermore, we believe another applicant for FY 2025 new 
technology add-on payments, TALVEYTM, may also be 
substantially similar to ELREXFIOTM. Per the application for 
TALVEYTM, TALVEYTM is a bispecific antibody 
approved for the treatment of adults with RRMM who have received at 
least four prior lines of therapy, including a PI, IMiD, and an anti-
CD38 monoclonal antibody. The applicant for TALVEYTM states 
TALVEYTM recruits CD3-expressing T cells to myeloma cells 
that express GPRC5D, resulting in activation of the T cell receptor 
pathway and lysis of GPRC5D-expressing MM cells. Per the applicant for 
TALVEYTM, TALVEYTM was available for sale 
immediately after its approval on August 9, 2023. We

[[Page 36047]]

believe TALVEYTM may be substantially similar to 
ELREXFIOTM because it is also a bispecific antibody that 
treats RRMM in patients who have previously received a PI, IMiD, and an 
anti-CD38 mAb. Additionally, we note that similar to 
ELREXFIOTM, the prescribing information for 
TALVEYTM includes the population with prior exposure to BCMA 
T-cell redirection therapy. Accordingly, as it appears that 
ELREXFIOTM and TALVEYTM would use the same or 
similar mechanism of action to achieve a therapeutic outcome, would be 
assigned to the same MS-DRG, and would treat the same or similar 
disease in the same or similar patient population, we believe that 
these technologies may also be substantially similar to each other such 
that they should be considered as a single application for purposes of 
new technology add-on payments. We note that if ELREXFIOTM 
is determined to only be substantially similar to TALVEYTM, 
and not TECVAYLI[supreg], we believe the newness period for 
ELREXFIOTM would begin on August 9, 2023, the date 
TALVEYTM received FDA approval.
    We are interested in receiving information on how these 
technologies may differ from each other with respect to the substantial 
similarity and newness criteria, to inform our analysis of whether 
ELREXFIOTM is substantially similar to TALVEYTM 
and/or TECVAYLI[supreg].
    We are inviting public comments on whether ELREXFIOTM is 
substantially similar to existing technologies and whether 
ELREXFIOTM meets the newness criterion.
    With respect to the cost criterion, to identify potential cases 
representing patients who may be eligible for ELREXFIOTM, 
the applicant searched the FY 2022 MedPAR for cases reporting one of 
the following ICD-10-CM codes in any position: C90.00 (Multiple myeloma 
not having achieved remission), C90.01 (Multiple myeloma in remission), 
or C90.02 (Multiple myeloma in relapse). Using the inclusion/exclusion 
criteria described in the following table, the applicant identified 
4,689 claims mapping to five MS-DRGs: MS-DRGs 840, 841, and 842 
(Lymphoma and Non-Acute Leukemia with MCC, with CC, and without CC/MCC, 
respectively), and MS-DRGs 846 and 847 (Chemotherapy without Acute 
Leukemia as Secondary Diagnosis with MCC and with CC, respectively). 
The applicant followed the order of operations described in the 
following table and calculated a final inflated average case-weighted 
standardized charge per case of $170,699, which exceeded the average 
case-weighted threshold amount of $77,190. Because the final inflated 
average case-weighted standardized charge per case exceeded the average 
case-weighted threshold amount, the applicant asserted that 
ELREXFIOTM meets the cost criterion.

    We are inviting public comments on whether ELREXFIOTM 
meets the cost criterion.
    With regards to the substantial clinical improvement criterion, the 
applicant asserted that ELREXFIOTM represents a substantial 
clinical improvement over existing technologies because it is a new 
treatment option for late-line RRMM patients who are refractory to or 
otherwise ineligible for existing therapy. Per the applicant, it 
significantly improves outcomes compared to existing therapy (Cohort A 
objective response rate (ORR) of 57.7 percent with a complete response 
(CR) or better achieved in 25.8 percent and very good partial response 
(VGPR) in 25.8 percent; Cohort B ORR of 33.3 percent with duration of 
response (DOR) of 84.3 percent at 9 months), has a manageable safety 
profile, and shorter hospitalization than TECVAYLI[supreg] and 
TALVEYTM. The applicant provided nine studies assessing 
ELREXFIOTM to support these claims, as well as 12 background 
articles about RRMM and comparator technologies.\35\ The following 
table summarizes the applicant's assertions regarding the substantial 
clinical improvement criterion. Please see the online posting for 
ELREXFIOTM for the applicant's complete statements regarding 
the substantial clinical improvement criterion and the supporting 
evidence provided.

BILLING CODE 4120-01-C
    After review of the information provided by the applicant, we have 
the following concerns regarding whether ELREXFIOTM meets 
the substantial clinical improvement criterion.
    With respect to the claim ELREXFIOTM is a new treatment 
option for late-line patients with RRMM who are refractory to existing 
therapies or otherwise ineligible for or unable to access them, the 
applicant states the nature of the disease is such that patients 
typically become refractory to the available treatment options or 
patients may be unable to access some therapies for other reasons. The 
applicant further notes patients need new therapies with new mechanisms 
of action that can provide better efficacy, extend the duration of 
response, and be available to a larger subset of the late-line RRMM 
population, particularly patients with prior BCMA-directed therapy 
exposure. The applicant states that ELREXFIOTM addresses 
these limitations since it does not require patient-specific 
manufacturing and is the only BCMA-directed bispecific antibody therapy 
that has clinical study data on outcomes for patients exposed to prior 
BCMA-directed therapy in its prescribing information. We note the 
evidence presented does not identify a specific population that would 
benefit from ELREXFIOTM that would not be eligible for or 
benefit from other therapies for late-line RRMM, including 
TECVAYLI[supreg], TALVEYTM, CARVYKTI[supreg], and 
ABECMA[supreg]. With regard to the population with prior BCMA-directed 
therapy exposure, as noted previously, the prescribing information for 
TALVEYTM also includes efficacy data in this population and 
the lack of inclusion of this population in the prescribing information 
for TECVAYLI[supreg] does not exclude the use of this drug for these 
patients.
    With respect to the claim that ELREXFIOTM is the only 
BCMA-directed bispecific antibody with clinical study data in the 
prescribing information to support use in patients who have been 
treated with prior BCMA-directed therapy, the applicant states that 
although clinical studies evaluating TECVAYLI[supreg] included prior 
BCMA-exposed RRMM patients, in Section 14 of the prescribing 
information,\36\ the

[[Page 36051]]

FDA-approved labeling does not acknowledge outcomes or safety data for 
prior BCMA-exposed patients. Furthermore, the applicant contends this 
lack of inclusion suggests that prior-BCMA exposed patients continue to 
have a high unmet need despite the availability of TECVAYLI[supreg], 
and that the inclusion of this clinical study data in 
ELREXFIOTM's prescribing information suggests that 
ELREXFIOTM is able to fill this unmet need. However, as 
noted previously, the lack of inclusion of similar study data in 
TECVAYLI[supreg]'s prescribing information does not exclude the use of 
this drug in these patients. Additionally, TALVEYTM is a 
bsAb that was also studied in this patient population and has an 
indication for patients with prior BCMA-directed therapy.
---------------------------------------------------------------------------

    \36\ TECVAYLI (teclistamab-cqyv), injection, for subcutaneous 
use; Janssen Biotech, Inc., 2023.
---------------------------------------------------------------------------

    With respect to the claim that CAR T-cell therapies are largely 
unavailable to Medicare beneficiaries with late-line RRMM, the 
applicant states CAR T-cells take a significant amount of time to 
manufacture, and given the rapid nature of RRMM, some patients may die 
or become ineligible for treatment by the time the CAR T-cells are 
available for infusion. However, we note that TECVAYLI[supreg] and 
TALVEYTM have also received FDA approval and would therefore 
be options for patients who are unable to access or receive CAR T-cell 
therapy.
    The applicant states that MM is an incurable malignancy and that 
patients' ability to respond to therapy diminishes over time, leading 
to a reduced duration of response and eventually exhausting available 
therapy options to manage the disease. The applicant asserts that 
patients typically undergo several lines of therapy before exhausting 
therapy options and succumbing to the disease. The applicant references 
the low objective response rates (ORRs) of selinexor and conventional 
chemotherapy in RRMM patients. We note there are several treatments 
available to patients with RRMM who have received at least four prior 
lines of therapy including a PI, an IMiD, and an anti-CD38 mAb, such as 
TECVAYLI[supreg], TALVEYTM, ABECMA[supreg], and 
CARVYKTI[supreg]. It is not clear from the evidence provided that there 
is a patient population eligible for and responsive to 
ELREXFIOTM that is neither eligible for nor responsive to 
any of these other available therapies.
    The applicant further claims that ELREXFIOTM's generally 
manageable safety profile without dysgeusia and other toxicities that 
severely impact quality of life, in conjunction with the improved 
efficacy in late-line RRMM, makes it a substantial clinical improvement 
treatment over existing therapies. Additionally, the applicant asserts 
that dysgeusia and nail-related and skin-related toxicities that reduce 
quality of life with TALVEYTM are not reported with 
ELREXFIOTM. However, the safety profile of 
ELREXFIOTM was not compared to ABECMA[supreg], 
CARVYKTI[supreg], or TECVAYLI[supreg]. We also note we did not receive 
evidence related to improved efficacy that compares 
ELREXFIOTM with ABECMA[supreg], CARVYKTI[supreg], 
TALVEYTM, or TECVAYLI[supreg], and we question if 
ELREXFIOTM improves efficacy relative to these other 
therapies.
    With respect to the claim that ELREXFIOTM significantly 
improves outcomes compared to existing therapies approved for late-line 
RRMM, including prior BCMA-exposed patients, the applicant provides 
study results from MagnetisMM-3, an open-label, phase 2 study where 
after receiving two step-up priming doses, patients received 
subcutaneous ELREXFIOTM once weekly in 28-day cycles, which 
after six cycles, was followed by once every 2 weeks for persistent 
responders.\37\ The applicant stated the ORR for ELREXFIOTM 
was 61 percent and the percentage of patients that had at least a 
complete response was 37.4 percent after a median follow-up of 17.6 
months in patients with RRMM and no prior exposure to BCMA-directed 
therapy.\38\ The applicant acknowledges the lack of head-to-head 
studies and submits indirect comparison analyses comparing 
ELREXFIOTM to belantamab, selinexor-dexamethasone, real-
world physician's choice of treatment, real-world external control 
arms, and TECVAYLI[supreg] in patients with triple-class refractory 
multiple myeloma. The referenced indirect comparisons by Hlavacek et 
al. (2023) \39\ and Costa et al. (2023) 40 41 showed the ORR 
for ELREXFIOTM was significantly higher compared to 
belantamab, selinexor-dexamethasone, real-world physician's choice of 
treatment based on local clinical practice, and real-world external 
control arms. We note, however, that no similar comparative analyses 
were provided by the applicant to compare ELREXFIOTM to 
TALVEYTM ABECMA[supreg], or CARVYKTI[supreg] . In the 
absence of direct comparative trials between ELREXFIOTM and 
TECVAYLI[supreg], the applicant submitted the results of an unanchored 
matching-adjusted indirect comparison (MAIC) between the MagnetisMM-3 
study, previously described, and the MajesTEC-1 study, assessing the 
relative efficacy of the two therapies in patients with relapsed or 
refractory MM na[iuml]ve to prior BCMA-directed therapy (Isha Mol et 
al., 2023).\42\ MajesTEC-1 was an open-label, phase 1-2 study where 
patients with RRMM and no prior exposure to BCMA-targeted therapy 
received a weekly subcutaneous injection of TECVAYLI[supreg] after two 
step-up doses.\43\ As stated by the applicant, the results of the MAIC 
demonstrate ELREXFIOTM significantly improved ORR and PFS 
versus TECVAYLI[supreg]. We note, however, that the mechanism used in 
the MAIC to reweight MagnetisMM-3 patients to match the baseline 
characteristics of patients from MajesTEC-1 is unclear, as is the 
sensitivity analysis in which missing values of the adjusted baseline 
characteristics for ELREXFIOTM patients were imputed by a 
random sample of the observations in MagnetisMM-3 to potentially 
increase the effective sample size. In addition, while the ORR and PFS 
in the two analyses (base case adjusted and sensitivity analysis) were 
significantly improved with ELREXFIOTM over 
TECVAYLI[supreg], we note that the confidence intervals were wide, 
reducing the certainty in these conclusions. The ORR odds ratio 95 
percent confidence interval was 1.01 to 3.19 for the base case adjusted 
analysis and 1.04 to 3.14 for the sensitivity analysis. Furthermore, 
other outcomes

[[Page 36052]]

measured, such as the duration of response and overall survival, did 
not demonstrate significant improvement with ELREXFIOTM. 
Additionally, we note that with regard to the claim that 
ELREXFIOTM significantly improves outcomes specifically in 
RRMM patients who have had prior BMCA-directed therapy, the applicant 
references the ELREXFIOTM prescribing information and 
additional MagnetisMM-3 Cohort B data showing an ORR of 33.3 percent in 
patients with prior BCMA-directed antibody drug conjugate (ADC) or CAR 
T-cell therapy. However, we note that TECVAYLI[supreg] and 
TALVEYTM may also be treatment options for BCMA-exposed 
patients and we would appreciate information on comparative efficacy 
between ELREXFIOTM and these treatment options in the prior 
BCMA-directed therapy population.

    With respect to the claim that ELREXFIOTM offers fewer 
hospitalization days during the step-up dosing period than other 
bispecific antibodies approved for patients with RRMM, thus lowering 
barriers to patient access, the applicant references the prescribing 
information for ELREXFIOTM, TECVAYLI[supreg], and 
TALVEYTM to indicate that assuming patients are not sent 
home between step-up doses, based on the step-up dosing schedules, the 
patient would be hospitalized for 5 days with ELREXFIOTM, 9 
days with TECVAYLI[supreg], and 9 to 12 days with TALVEYTM. 
While the shorter step-up dosing may lead to a shorter hospitalization, 
the applicant assumes, but does not demonstrate that the shorter step-
up dosing period and potentially shorter hospitalization would lower 
barriers to patient access. Additionally, we note that there are other 
variables besides duration of inpatient stay for the step-up dosing 
that may affect availability or access to therapies, such that a 
shorter step-up dosing duration may not necessarily result in better 
access to therapy. For instance, social, financial, age-related, prior 
therapy, and patient and provider dosing preferences may also affect 
access to therapy. Furthermore, while the shorter step-up dosing 
schedule should theoretically lead to a shorter hospitalization, we 
note that the risk and severity of adverse drug events and patient 
response could vary by drug, and that no clinical data was provided to 
support this claim.
    We are inviting public comments on whether ELREXFIOTM 
meets the substantial clinical improvement criterion.
    We did not receive any written comments in response to the New 
Technology Town Hall meeting notice published in the Federal Register 
regarding the substantial clinical improvement criterion for 
ELREXFIOTM.
e. FloPatch FP120
    Flosonics Medical (R.A. 1929803 Ontario Corp.) submitted an 
application for new technology add-on payments for FloPatch FP120 for 
FY 2025. According to the applicant, FloPatch FP120 is a wireless, 
wearable, continuous wave (4 MHz) Doppler ultrasound device that 
adheres over peripheral vessels (that is, carotid & jugular) that 
assesses blood flow in the peripheral vessels, enabling rapid and 
repeatable dynamic assessments of both arterial and venous flow 
simultaneously. According to the applicant, the FloPatch FP120 
cardiovascular blood flowmeter adheres to a patient's neck (or any 
other major vessel) and transmits Doppler-shifted ultrasonic waves from 
the transducer to the artery and vein at a fixed angle of insonation 
that are then reflected by moving blood cells back to the transducer. 
Per the applicant, the signal processing unit wirelessly outputs data 
to a secure iOS mobile medical application, which displays metrics from 
the Doppler signal, such as maximal velocity trace and corrected flow 
time, in a user-friendly interface. Per the applicant, FloPatch FP120 
will optimize clinical workflow, is easy-to-use and hands-free, cloud-
connected, and can be deployed in under one minute, providing 
instantaneous results.
    Please refer to the online application posting for FloPatch FP120, 
available at https://mearis.cms.gov/public/publications/ntap/NTP231017D56F4, for additional detail describing the technology and the 
types of conditions that the technology might help diagnose and/or 
treat.
    With respect to the newness criterion, according to the applicant, 
FloPatch FP120 received 510(k) clearance from FDA on May 3, 2023 for 
use for the noninvasive assessment of blood flow in the carotid artery. 
Per the applicant, in a more recent FDA 510(k) submission, the proposed 
indication is for use for the noninvasive assessment of blood flow in 
peripheral vasculature. However, based on the application submitted by 
the applicant, the new technology add-on payment application for 
FloPatch FP120 is not eligible for consideration for FY 2025 for the 
proposed indication (for use for the noninvasive assessment of blood 
flow in peripheral vasculature) because documentation of FDA acceptance 
or filing of the marketing authorization request, that indicates that 
FDA has determined that the application is sufficiently complete to 
allow for substantive review by FDA, was not provided to CMS at the 
time of new technology add-on payment application submission. As such, 
the new technology add-on payment application for FloPatch FP120 is 
only eligible for consideration for FY 2025 for the narrower indication 
for use for the noninvasive assessment of blood flow in carotid artery.
    We note that prior to the May 3, 2023 clearance, there were two FDA 
510(k) clearances for the FloPatch FP120; one obtained in 2022 and one 
in 2020. The indications in the 2020, 2022, and 2023 clearances are 
identical, that is, for use for the noninvasive assessment of blood 
flow in the carotid artery.\44\ In addition, the 2020 clearance was 
based on substantial equivalence to the FloPatch FP110 device,\45\ 
which was an earlier version of FloPatch FP120 and was also FDA-
cleared. According to the applicant, FloPatch FP120 was commercially 
available for this use as of January 1, 2023. However, as noted 
earlier, the provided FDA 510(k) clearance was dated May 3, 2023. 
Because the market availability date as indicated by the applicant 
preceded the 2023 clearance date, and because the 2020 and 2022 
clearances had the same indication as the 2023 clearance, we question 
when the technology first became commercially available for use for the 
noninvasive assessment of blood flow in the carotid artery and request 
additional information on the market availability date for this 
indication. Per the applicant, one FloPatch FP120 device would be used 
per inpatient stay.

---------------------------------------------------------------------------

    According to the applicant, there are currently no ICD-10-PCS 
procedure codes to distinctly identify FloPatch FP120. We note that the 
applicant submitted a request for approval for a unique ICD-10-PCS 
procedure code for FloPatch FP120 beginning in FY 2025. The applicant 
provided a list of diagnosis codes that may be used to currently 
identify the indication for FloPatch FP120 under the ICD-10-CM coding 
system. Please refer to the online application posting for the complete 
list of ICD-10-CM codes provided by the applicant.
    As previously discussed, if a technology meets all three of the 
substantial similarity criteria under the newness criterion, it would 
be considered substantially similar to an existing technology and would 
not be considered new for the purpose of new technology add-on 
payments.

[[Page 36053]]

    With respect to the substantial similarity criteria, the applicant 
asserted that FloPatch FP120 is not substantially similar to other 
currently available technologies because FloPatch FP120 offers real-
time, non-invasive monitoring of hemodynamic changes of both the 
arterial and venous blood flow, improving fluid management decisions. 
Per the applicant, FloPatch FP120 surpasses current methods by 
providing continuous data, enhancing patient safety, and addressing 
unmet clinical needs for immediate, precise assessments, and therefore, 
the technology meets the newness criterion. The following table 
summarizes the applicant's assertions regarding the substantial 
similarity criteria. Please see the online application posting for 
FloPatch FP120, for the applicant's complete statements in support of 
its assertion that FloPatch FP120 is not substantially similar to other 
currently available technologies.

BILLING CODE 4120-01-C

[[Page 36054]]

    We note the following concerns with regard to the newness 
criterion. With respect to the first substantial similarity criterion, 
whether FloPatch FP120 uses the same or similar mechanism of action for 
a therapeutic outcome when compared to existing technologies, we note 
we did not receive information from the applicant regarding predicate 
devices for FloPatch FP120 that were previously FDA-cleared in its 
discussion of existing technologies. As noted, there are three prior 
FDA 510(k) clearances for the FloPatch FP120, with the same indication 
for use for the noninvasive assessment of blood flow in the carotid 
artery.\46\ In addition, the 2020 clearance was based on substantial 
equivalence to the FloPatch FP110 device,\47\ which was an earlier 
version of FloPatch FP120 and was also FDA-cleared. We note that all of 
the FloPatch FP120 FDA-cleared devices, as well as the FP110 version 
have an identical method of attachment of the ultrasound probe to the 
human body, and the same intended use and indications for use. 
Accordingly, as the technology was already approved for use for this 
same indication outside of the 2- to 3-year newness period, it appears 
that it would no longer be considered new for purposes of new 
technology add-on payments.
---------------------------------------------------------------------------

    \46\ K223843, May 3, 2023; K222242, December 9, 2022; and 
K200337, March 24, 2020.
    \47\ K191388, June 21, 2019.
---------------------------------------------------------------------------

    In addition, we question whether a different placement method or 
the addition of a wearable functionality for the noninvasive assessment 
of blood flow would constitute a different mechanism of action, and 
also whether these differences may instead be relevant to the 
assessment of substantial clinical improvement, rather than of newness. 
For example, while the applicant described FloPatch FP120 as user-
friendly, we question whether ease-of-use in itself represents a 
mechanism of action unique from existing technologies for a therapeutic 
outcome, as the primary underlying mechanism of action is still Doppler 
ultrasound technology.
    With respect to the second substantial similarity criterion, that 
is, whether a product is assigned to the same or a different MS-DRG, 
although the applicant asserts that the device is new and has not 
undergone sufficient review to be recognized as a treatment within the 
existing MS-DRGs, we note that the applicant stated that FloPatch FP120 
could be relevant to existing MS-DRGs that pertain to septicemia or 
severe sepsis for the assessment of volume responsiveness. We believe 
that, based on its indication, cases involving the use FloPatch FP120 
would be assigned to the same MS-DRGs as those involving existing 
technologies used for invasive and non-invasive measurements of blood 
flow, such as for patients with septicemia or severe sepsis.
    With respect to the third substantial similarity criterion, that 
is, whether the technology involves treatment of the same or similar 
type of disease or patient population when compared to an existing 
technology, the applicant maintained that existing technologies do not 
provide clinicians with the information they need, and while FloPatch 
LP120 serves a similar purpose as existing technology, its process has 
been optimized by providing a safer, more accurate, and instantaneous 
method of assessment. While this may be relevant to the assessment of 
substantial clinical improvement, it does not appear to be related to 
newness, and we remain unclear about how the patient population for 
which FloPatch FP120 is used differs from other patients for which 
existing non-invasive (for example, Doppler ultrasound devices) and 
invasive technologies are used for hemodynamic monitoring in a same or 
similar type of disease (such as septicemia or severe sepsis).
    Accordingly, as it appears that the May 3, 2023 FDA 510(k) 
clearance and prior FDA 510(k) clearances for FloPatch FP120 may use 
the same or similar mechanism of action to achieve a therapeutic 
outcome, would be assigned to the same MS-DRG, and treat the same or 
similar patient population and disease, we believe that these 
technologies may be substantially similar to each other. We note that 
if FloPatch FP120 as described in its 2023 FDA 510(k) clearance is 
substantially similar to prior versions as described in the 2022 and 
2020 FDA 510(k) clearances, we believe the newness period for this 
technology would begin on March 24, 2020 with the earliest FDA 510(k) 
clearance date for FloPatch FP120 (K200337) and therefore, because the 
3-year anniversary date of the technology's entry onto the U.S. market 
(March 24, 2023) occurred in FY 2023, the technology would no longer be 
considered new and would not be eligible for new technology add-on 
payments for FY 2025.
    We are inviting public comments on whether FloPatch FP120 is 
substantially similar to existing technologies and whether FloPatch 
FP120 meets the newness criterion.
    With respect to the cost criterion, to identify potential cases 
representing patients who may be eligible for FloPatch FP120, the 
applicant searched the FY 2022 MedPAR for cases with ICD-10-CM 
diagnosis code category of E877 (Fluid overload, unspecified) and MS-
DRG codes for septicemia or severe sepsis. Using the inclusion/
exclusion criteria described in the following table, the applicant 
identified 690,320 cases mapping to septicemia or severe sepsis MS-
DRGs. The applicant followed the order of operations described in the 
following table and calculated a final inflated average case-weighted 
standardized charge per case of $93,703, which exceeded the average 
case-weighted threshold amount of $70,142. Because the final inflated 
average case-weighted standardized charge per case exceeded the average 
case-weighted threshold amount, the applicant asserted that FloPatch 
FP120 meets the cost criterion.
BILLING CODE 4120-01-P

[[Page 36055]]

[GRAPHIC] [TIFF OMITTED] TP02MY24.095

BILLING CODE 4120-01-C
    We note the following concern regarding the cost criterion. Per the 
applicant, FloPatch FP120 is not indicated for use for a particular 
disease or diagnosis, but rather to assess changes in blood flow in 
response to a preload challenge and that it monitors hemodynamic change 
in response to a clinical intervention. We note that the applicant 
limited their coding determination and cost analysis to cases 
associated with a diagnosis of septicemia or severe sepsis with the 
identified MS-DRGs, 870, 871, and 872, as these are the cases for which 
FloPatch FP120 is best suited. However, the applicant stated that 
patients who are categorized under MS-DRGs other than 870, 871, and 872 
can develop sepsis even though they are not initially admitted under a 
sepsis-related DRG, such as post-surgical patients or patients admitted 
for acute conditions like heart failure or chronic illnesses such as 
diabetes or renal disease. As these patients may also require vigilant 
monitoring for sepsis and fluid overload in a broader range of clinical 
scenarios, we are interested in additional information regarding 
whether such cases using the technology would map to other DRGs, and if 
those cases should also be included in the cost analysis.
    We are inviting public comments on whether FloPatch FP120 meets the 
cost criterion.
    With regard to the substantial clinical improvement criterion, the 
applicant asserted that FloPatch FP120 overcomes barriers associated 
with traditional flow-directed therapies, which are often invasive and 
require specific expertise, by offering a non-invasive, user-friendly 
alternative. Per the applicant, the FloPatch FP120 makes precision 
fluid management more accessible, enabling early detection of preload 
unresponsiveness, thereby minimizing complications from over-
resuscitation. The applicant asserted that FloPatch FP120 offers a 
treatment option for a patient population unresponsive to, or 
ineligible for, currently available treatments; offers the ability to 
diagnose a medical condition in a patient population where that medical 
condition is currently undetectable or offers the ability to diagnose a 
medical condition earlier in a patient population than allowed by 
currently available methods; and that use of FloPatch FP120 
significantly improves clinical outcomes relative to services or 
technologies previously available. The applicant provided five studies 
to support these claims. We also note that seven other articles 
submitted as supporting evidence should more appropriately be 
characterized as background articles because they do not directly 
assess the use of FloPatch FP120. Instead, those seven articles focus 
on the relationship between fluid responsiveness status during septic 
shock resuscitation.\48\ The following table summarizes the applicant's 
assertions regarding the substantial clinical improvement criterion. 
Please see the online posting for FloPatch FP120 for the applicant's 
complete statements regarding the substantial clinical improvement 
criterion and the supporting evidence provided.

    We note the following concerns regarding whether FloPatch FP120 
meets the substantial clinical improvement criterion.
    In support of its assertion that FloPatch FP120 offers a treatment 
option for a patient population unresponsive to, or ineligible for, 
currently available treatments, the applicant stated that FloPatch 
FP120 improves patient accessibility to flow-directed therapy. The 
applicant referred to the Kenny et al. (2021a) \49\ study that focused 
on a novel, hands-free CW Doppler patch developed for easily and 
continuously monitoring changes in blood flow velocities in the common 
carotid artery. The study included in vitro experiments conducted using 
moving string and blood-mimicking flow phantoms; a small usability 
study with 22 participants, and an in vivo proof-of-concept study with 
one healthy volunteer and one congestive heart failure patient. While 
the study found that the CW Doppler patch demonstrated accuracy in 
identifying changes in target velocity in string and flow phantom 
experiments, that it was easy to use, and that the Doppler patch could 
continuously record and track instantaneous changes in carotid velocity 
time integral (VTI) during a passive leg raise, we question if the 
evidence demonstrates that the FloPatch FP120 substantially improves 
patient accessibility to flow directed therapy relative to existing 
technologies. We would be interested in evidence comparing the use of 
FloPatch FP120 and existing technologies to demonstrate improvements in 
patient accessibility. In addition, we note that the study had small 
sample sizes, which may raise concerns about the reliability of the 
findings.

novel, hands-free ultrasound patch for continuous monitoring of 
quantitative Doppler in the carotid artery. Scientific Reports 
11(1):1-11.
---------------------------------------------------------------------------

    To support its claim that FloPatch FP120 improves patient 
accessibility to flow-directed therapy, the applicant also included 
findings from the Kenny et al. (2023a) \50\ study about the time cost 
of physiologically ineffective intravenous fluid in the emergency 
department (ED). Per the applicant, this study sought to

[[Page 36057]]

quantify the burden of fluid unresponsiveness early in ED care and 
calculate the time spent providing physiologically ineffective IV fluid 
using FloPatch FP120. It was a prospective study design, using a 
convenience sample of 51 adult patients presenting to a single 
community ED requiring IV fluid expansion for any indication, and 
identified 86 preload challenges, and 19,667 carotid Doppler beats. The 
study authors concluded that a clinically significant fraction of fluid 
unresponsive or refractory patients was observed early in their ED 
care, and a considerable amount of time was spent providing 
physiologically ineffective IV fluid, and that these findings may 
indicate an area in ED care where using wearable Doppler ultrasound 
technology, like FloPatch FP120, would improve clinical efficiency. We 
question whether these findings can be replicated in studies with a 
larger sample. We also question if a study using a patient sample 
representative of those potentially appropriate for FloPatch FP120 
would yield similar results as one using a convenience sample. In 
addition, we are interested in whether a multi-center trial would 
generate the same result as a single-site study, where site-specific 
attributes could potentially confound study results, reducing the 
reliability of the findings.

---------------------------------------------------------------------------

    The applicant also asserted that FloPatch FP120 is able to diagnose 
sepsis in a population where sepsis is currently undetectable, or to 
diagnose it earlier than currently available technologies. The 
applicant claimed that diagnosing preload unresponsiveness early in 
care is important because doing so reduces complications. However, 
although the applicant provided studies demonstrating that FloPatch 
FP120 can diagnose sepsis, these studies do not appear to demonstrate 
that the use of the technology to make a diagnosis affected the 
management of the patients, as required under Sec.  
412.87(b)(1)(ii)(B). For example, in the Kenny et al. (2023a) \51\ 
study on time cost of physiologically ineffective intravenous fluids in 
the ED, as discussed earlier, there was no evidence linking the use of 
FloPatch FP120 to changes in the management of patients such as 
initiating or discontinuing IV fluid expansion.

---------------------------------------------------------------------------

    To further support its claim that diagnosing preload 
unresponsiveness early in care is important because doing so reduces 
complications, the applicant also used the Kenny et al. (2021c) \52\ 
study about correlation between carotid Doppler ultrasonography and 
stroke volume. The study found that compared with existing handheld 
Doppler devices, FloPatch FP120 was able to capture and analyze a large 
number of cardiac cycles, account for inherent SV variation over many 
cardiorespiratory cycles, and eliminate the effects of human errors. 
The applicant hypothesized that when measured over many cardiac cycles, 
monitoring SV change using FloPatch FP120 might support diagnosis and 
management of evolving hypovolemia. While this study and those 
discussed earlier demonstrated that FloPatch FP120 provided noninvasive 
assessment of blood flow to determine SV changes, similar to our 
previous concern, we remain interested in evidence showing how use of 
the technology to make a diagnosis affects the management of patients, 
such as the use of FloPatch FP120 to initiate or discontinue IV fluid 
expansion in response to the observed SV changes.

---------------------------------------------------------------------------

    The applicant also referred to the findings of the Kenny et al. 
(2023b) \53\ study on simultaneous venous-arterial Doppler during 
preload augmentation to support its claim that diagnosing preload 
unresponsiveness early in care is important because it reduces 
complications. In that study, the researchers concluded that FloPatch 
FP120 (referenced as the wearable Doppler biosensor) can help identify 
patients with dynamic fluid intolerance, potentially guiding IV fluid 
management and preventing downstream complications and costs. We are 
concerned that the small clinical sample size and presence of potential 
confounders could call into question the reliability and validity of 
the findings. In addition, we note that this study does not appear to 
demonstrate that use of FloPatch FP120 to assess preload responsiveness 
affected the management of the patients, as the study states that the 
treating clinician was blinded to the results of the wearable 
ultrasound and that the choice for preload augmentation was at the 
discretion of the treating clinician.

---------------------------------------------------------------------------

    To support the assertion that FloPatch FP120 significantly improves 
clinical outcomes relative to services or technologies previously 
available, the applicant claimed that current services for sepsis 
patients are providing IV fluids without flow guidance, and referred to 
three Kenny studies (2021a, 2023a, and 2023b), discussed earlier. As 
discussed, we are interested in additional evidence that assesses the 
impact of FloPatch FP120 compared to existing technologies that can be 
used to provide flow guidance on clinical outcomes.

applicant, HEPZATOTM KIT is a drug/device combination 
product consisting of melphalan and the Hepatic Delivery System (HDS), 
indicated as a liver-directed treatment for adult patients with uveal

agent melphalan hydrochloride is delivered intra-arterially to the 
liver with simultaneous extracorporeal filtration of hepatic venous

    Please refer to the online application posting for 
HEPZATOTM KIT, available at https://mearis.cms.gov/public/publications/ntap/NTP2310160RLLX, for additional detail describing the 
technology and the disease treated by the technology.
    With respect to the newness criterion, according to the applicant, 
HEPZATOTM KIT was granted approval as a New Drug Application 
(NDA) from FDA on August 14, 2023, for use as a liver-directed 
treatment for adult patients with uveal melanoma with unresectable 
hepatic metastases affecting less than 50 percent of the liver and no 
extrahepatic disease or extrahepatic disease limited to the bone, lymph 
nodes, subcutaneous tissues, or lung that is amenable to resection or 
radiation. According to the

[[Page 36058]]

applicant, the technology became available for sale on January 8, 2024, 
because manufacturing did not commence until after FDA approval was 
granted. Melphalan hydrochloride, a component of the 
HEPZATOTM KIT, is administered by intra-arterial infusion 
into the hepatic artery at a dose of 3 mg/kg of body weight with a 
maximum dose of 220 mg during a single HEPZATO treatment. The drug is 
infused over 30 minutes, followed by a 30-minute washout period. 
According to the applicant, treatments should be administered every 6 
to 8 weeks, but can be delayed until recovery from toxicities, and as 
per clinical judgement.
    The applicant stated that, effective October 1, 2023, the following 
ICD-10-PCS code may be used to uniquely describe procedures involving 
the use of HEPZATOTM KIT: XW053T9 (Introduction of melphalan 
hydrochloride antineoplastic into peripheral artery, percutaneous 
approach, new technology group 9). The applicant provided a list of 
diagnosis codes that may be used to currently identify the indication 
for HEPZATOTM KIT under the ICD-10-CM coding system. Please 
refer to the online application posting for the complete list of ICD-
10-CM and ICD-10-PCS codes provided by the applicant.
    As previously discussed, if a technology meets all three of the 
substantial similarity criteria under the newness criterion, it would 
be considered substantially similar to an existing technology and would 
not be considered ``new'' for the purpose of new technology add-on 
payments.
    With respect to the substantial similarity criteria, the applicant 
asserted that HEPZATOTM KIT is not substantially similar to 
other currently available technologies because it offers the first 
liver-directed treatment option to patients with liver-dominant 
metastatic ocular melanoma (mOM) who may be poor candidates for liver 
resection and/or who may have difficulty tolerating systemic 
chemotherapy. According to the applicant, HEPZATOTM KIT uses 
a unique PHP procedure to isolate liver circulation and deliver a high 
concentration of melphalan to liver tumors via infusion followed by 
filtration of the hepatic venous flow to remove melphalan out of the 
blood with extracorporeal filters, and that therefore, the technology 
meets the newness criterion. The following table summarizes the 
applicant's assertions regarding the substantial similarity criteria. 
Please see the online application posting for HEPZATOTM KIT 
for the applicant's complete statements in support of its assertion 
that HEPZATOTM KIT is not substantially similar to other 
currently available technologies.

    We are inviting public comments on whether HEPZATOTM KIT 
is substantially similar to existing technologies and whether 
HEPZATOTM KIT meets the newness criterion. We are also 
inviting public comments on drug-device combination technology 
considerations for new technology add-on payments. Specifically, we 
seek comment on whether reformatting the delivery mechanism for a drug 
would represent a new mechanism of action for drug-device combination 
technologies, and on factors that should be considered when considering 
new technology add-on payments for technologies that may use a drug or 
device component that is no longer new in combination with a new drug 
or device component.
    With respect to the cost criterion, the applicant provided multiple 
analyses to demonstrate that it meets the cost criterion. For each 
analysis, the applicant searched the FY 2022 MedPAR file using a 
combination of ICD-10-CM and/or PCS codes to identify potential cases 
representing patients who may be eligible for HEPZATOTM KIT. 
The applicant explained that it used different codes to demonstrate 
different cohorts that may be eligible for HEPZATOTM KIT 
because it is indicated for a rare condition, hepatic-dominant mOM, 
which does not have a unique ICD-10-CM diagnosis code to identify 
potential cases with the specific diagnosis of interest, nor a unique 
ICD-10-PCS procedure code that would identify patients receiving this 
specific procedure. The applicant believed the cases identified in the 
analysis are the closest proxies to the cases potentially eligible for 
the use of HEPZATOTM KIT. Each analysis followed the order 
of operations described in the table later in this section.
    For the first analysis, the applicant searched for cases with ICD-
10-PCS code 3E05305 (Introduction of other antineoplastic into 
peripheral artery, percutaneous approach) for the PHP procedure, and 
ICD-10-CM code Z51.11 (Encounter for antineoplastic chemotherapy) as 
the primary diagnosis for the administration of chemotherapy during an 
inpatient stay. In addition, the applicant narrowed the analysis to 
cases with liver-dominant mOM using at least one secondary liver 
metastases diagnosis plus at least one ocular melanoma diagnosis. 
Please see the online posting for HEPZATOTM KIT for the 
complete list of codes provided by the applicant. The applicant used 
the inclusion/exclusion criteria described in the following table. 
Under this analysis, the applicant identified 11 claims mapping to one 
MS-DRG: 829 (Myeloproliferative Disorders or Poorly Differentiated 
Neoplasms with Other Procedures with CC/MCC). The applicant calculated 
a final inflated average case-weighted standardized charge per case of 
$1,068,530, which exceeded the average case-weighted threshold amount 
of $104,848.
    For the second analysis, the applicant searched for the following 
combination of ICD-10-CM diagnosis codes: Z51.11 (Encounter for 
antineoplastic chemotherapy) as the primary diagnosis code, in 
combination with at least one of the following secondary liver 
metastases codes: C78.7 (Secondary malignant neoplasm of liver and 
intrahepatic bile duct), or C22.9 (Malignant neoplasm of liver, not 
specified as primary or secondary). The applicant used the inclusion/
exclusion criteria described in the following table. Under this 
analysis, the applicant identified 1,134 claims mapping to nine MS-
DRGs, with 94 percent of identified cases mapping to three MS-DRGs: 829 
(Myeloproliferative Disorders or Poorly Differentiated Neoplasms with 
Other Procedures with CC/MCC), as well as 846 and 847 (Chemotherapy 
without Acute Leukemia as Secondary Diagnosis with MCC, and with CC, 
respectively). The applicant calculated a final inflated average case-
weighted standardized charge per case of $1,066,207, which exceeded the 
average case-weighted threshold amount of $81,652.
    For the third analysis, the applicant searched for cases where the 
ICD-10-CM code Z51.11 (Encounter for antineoplastic chemotherapy) is 
the primary diagnosis or the ICD-10 PCS code 3E05305 (Introduction of 
other antineoplastic into peripheral artery, percutaneous approach) is 
reported. In addition, the case also needed to include at least one of 
the following secondary liver metastases codes: C78.7 (Secondary 
malignant neoplasm of liver and intrahepatic bile duct) or C22.9 
(Malignant neoplasm of liver, not specified as primary or secondary). 
The applicant used the inclusion/exclusion criteria described in the 
following table. Under this analysis, the applicant identified 1,277 
claims mapping to 12 MS-DRGs with 92 percent of identified cases 
mapping to three MS-DRGs: 829 (Myeloproliferative Disorders or Poorly 
Differentiated Neoplasms with Other Procedures with CC/MCC); as well as 
846 and 847 (Chemotherapy without Acute Leukemia as Secondary Diagnosis 
with MCC, and with CC, respectively). The applicant calculated a final 
inflated average case-weighted standardized charge per case of 
$1,067,772, which exceeded the average case-weighted threshold amount 
of $80,245.
    For the fourth analysis, the applicant searched for cases reporting 
the following combination of ICD-10-CM diagnosis codes: C78.7 
(Secondary malignant neoplasm of liver and intrahepatic bile duct) or 
C22.9 (Malignant neoplasm of liver), in combination with at least one 
ocular melanoma ICD-10-CM code. Please see the online posting for 
HEPZATOTM KIT for the complete list of codes provided by the 
applicant. The applicant used the inclusion/exclusion criteria 
described in the following table. Under this analysis, the applicant 
identified 1,059 claims mapping to 91 MS-DRGs with none exceeding 4.91 
percent. The applicant calculated a final inflated average case-
weighted standardized charge per case of $1,062,553, which exceeded the 
average case-weighted threshold amount of $66,104.
    Because the final inflated average case-weighted standardized 
charge per case exceeded the average case-weighted threshold amount in 
all scenarios, the applicant asserted that HEPZATOTM KIT 
meets the cost criterion.

    We are inviting public comments on whether HEPZATOTM KIT 
meets the cost criterion.
    With regard to the substantial clinical improvement criterion, the 
applicant asserted that HEPZATOTM KIT represents a 
substantial clinical improvement over existing technologies because it 
offers a minimally invasive, targeted, effective, and safe treatment 
option to patients with liver-dominant mOM who may be poor candidates 
for liver resection or who may have difficulty tolerating systemic 
chemotherapy which results in a substantial clinical improvement in 
response and survival rates over best available care and quality of 
life compared to pre-treatment. The applicant provided 11 studies to 
support these claims, as well as one background article about use of 
chemosaturation with PHP (CS-PHP) as a palliative treatment option for 
patients with unresectable cholangiocarcinoma.\55\ The following table 
summarizes the applicant's assertions regarding the substantial 
clinical improvement criterion. Please see the online posting for

BILLING CODE 4120-01-C
    After review of the information provided by the applicant, we have 
the following concerns regarding whether HEPZATOTM KIT meets 
the substantial clinical improvement criterion. With respect to the 
applicant's assertion that HEPZATOTM KIT offers a treatment 
option for a patient population unresponsive or ineligible for 
currently available treatments, while the applicant stated that 
HEPZATOTM KIT offers an additional treatment option to 
patients with liver-dominant mOM who may be poor candidates for liver 
resection or who may have difficulty tolerating systemic chemotherapy, 
it did not provide evidence in support of this assertion. We would be 
interested in information regarding whether there are potential 
Medicare patient populations that may have difficulty tolerating (or be 
unresponsive to) KIMMTRAK[supreg] or other currently available 
treatments, but would be a good candidate for HEPZATOTM KIT.

[[Page 36065]]

    Regarding the claim that HEPZATOTM KIT improves survival 
over other treatment options, the applicant provided seven peer-
reviewed cohort studies, summary material from an unpublished study, 
and one randomized controlled clinical study to support the claim.
    The seven peer reviewed cohort studies 
56 57 58 59 60 61 62 provide a range of results of overall 
survival as reported for patients treated with the HEPZATOTM 
KIT (median overall survival after first Chemosaturation with 
Percutaneous Hepatic Perfusion [CS-PHP] ranged from 9.6 months to 27.4 
months depending on the study, and median one-year overall survival 
rate raged from 44 percent to 77 percent depending on study). A few of 
the seven peer reviewed cohort studies (Karydis et al. (2018), Tong et 
al. (2022); Meier et al. (2021)) reported statistically significant 
improvement in overall survival (OS) when compared to non-responders or 
stable disease groups. Only one of the seven studies, Dewald et al. 
(2021), compared results to alternative treatments, but statistical 
significance was not achieved (P = 0.97) with CS-PHP resulting in a 
median OS of 24.1 months compared with 23.6 months for patients 
receiving other therapies. We believe that additional evidence 
supporting that HEPZATOTM KIT offers a significant 
difference in OS rates compared to currently available treatments would 
be helpful in our evaluation of the applicant's assertion. We note that 
several of the studies provided as evidence include small, non-
randomized studies without the use of comparators or controls, which 
may affect the ability to draw meaningful conclusions about treatment 
outcomes from the results of the studies. We also note that a majority 
of the studies provided (Bruning et al. (2020); Vogl et al. (2017); 
Dewald et al. (2021); Meijer et al. (2021); and Artzner et al. (2019)) 
were conducted outside the United States. We question if there may be 
differences in treatment guidelines between these countries that may 
have affected clinical outcomes.

---------------------------------------------------------------------------

    The applicant also submitted summary presentation material evidence 
to support this claim in the form of a poster and slides for the FOCUS 
study,\63\ in which 144 patients were enrolled, with 91 patients 
receiving percutaneous hepatic perfusion (PHP) treatment and 32 
patients receiving best available care (BAC). According to the 
applicant, preliminary results from the phase III FOCUS Trial show that 
progression free survival (PFS) was 9.03 months among PHP patients and 
just over 3 months among best available care (BAC) patients. OS among 
treated PHP patients was 19.25 months and among treated BAC patients 
was 14.49 months. However, this study has yet to be published and is 
not yet available for analysis and peer review. At this point, we are 
unable to verify the methods, results, and conclusions of this study as 
the applicant only provided evidence in the form of a poster and 
presentation. For example, one citation provided by the applicant in 
the form of a non-peer-reviewed conference presentation details 
preliminary results from the FOCUS Phase III Trial. We would be 
interested in the statistical analysis (including p value and CI data) 
surrounding the OS rates. In addition, the poster notes that due to 
slow enrollment and patient reluctance to receive BAC treatment, the 
trial design was amended to a single arm design with all eligible 
patients receiving PHP after discussion with FDA. We would be 
interested in detail about these specific eligibility requirements, as 
well as how the potential for confounding variables resulting from any 
differences in the resulting populations were identified and mitigated.

---------------------------------------------------------------------------

    In the published randomized clinical trial \64\ (RCT) provided by 
the applicant, the median hepatic progression free survival (hPFS), the 
primary endpoint of the trial, was 7.0 months for patients using 
HEPZATOTM KIT compared to 1.6 months for patients receiving 
BAC. However, the median overall survival (OS) with the treatment of 
HEPZATOTM KIT was 10.6 months (95 percent CI 6.9-13.6 
months) compared to 10.0 months (95 percent CI 6.0-13.1 months) for the 
group of patients who received BAC. The study notes that median OS was 
not significantly different (PHP-Mel 10.6 months vs. BAC 10.0 months), 
but OS was 13.1 months (95 percent CI 10.0-20.3 months) in BAC patients 
who crossed over and received treatment with PHP-Mel (n = 28, 57.1 
percent). In the study discussion of OS, Hughes, et al. concluded that 
the 57 percent of patients who were allowed to crossover confounded the 
ability to analyze any survival advantage associated with PHP Mel. We 
would be interested in additional evidence in our evaluation of the 
applicant's assertion that HEPZATOTM KIT substantially 
improves survival over other treatment options.

19.
---------------------------------------------------------------------------

    Regarding the claim that HEPZATOTM KIT increases 
response rate over BAC, we note that across the retrospective studies, 
response rates ranged from an overall response rate of 42.3 percent 
[Dewald et al (2021)] to a partial response of 89 percent [Vogl et al. 
(2017)] depending on the study. However, as the applicant cited to many 
of the same retroactive studies that it referenced in support of the 
claim of improved survival [Bruning et al. (2020); Vogl et al. (2017); 
Dewald et al. (2021); Meijer et al. (2021); Artzner et al. (2019); Tong 
et al. (2022); Karydis et al. (2018)], we have the same questions as 
discussed previously regarding the ability to draw meaningful 
conclusions from the results of these studies in evaluation of this 
claim.
    Regarding the unpublished FOCUS study (Delcath ASCO 2022 FOCUS 
Trial Poster),\65\ previously described, the applicant stated that in 
the preliminary results from the FOCUS Trial, the overall response rate 
(ORR) among PHP patients was 36.3 percent, nearly three

[[Page 36066]]

times better that the 12.5 percent ORR among BAC patients. However, as 
previously noted, we would be interested in details about the 
eligibility requirements, and how the potential for confounding 
variables resulting from any differences in the resulting populations 
were identified and mitigated.

---------------------------------------------------------------------------

    Lastly, with regard to the assertion that HEPZATOTM KIT 
improves quality of life over pre-treatment, the applicant submitted 
the Vogl et al. (2017) study as evidentiary support. The study was a 
retrospective, multi-center study reporting outcome and safety after 
percutaneous isolated hepatic perfusion (PIHP) with Melphalan for 
patients with uveal melanoma and metastatic disease limited to the 
liver. Thirty-five PIHP treatments were performed in 18 patients (8 
male, 10 female) at seven hospitals across the U.S and Germany between 
January 2012 and December 2016. Patients' life quality was assessed 
using four-point scale questionnaires to rate overall health and life 
quality after therapy, how much their health and quality of life had 
changed after therapy, and how pleased they were with PIHP. We note 
that the study used a subjective four-point measurement scale to 
determine quality-of-life used in the study. We question if a more 
objective assessment tool would be more helpful in evaluating a 
patient's quality of life. It is unclear if the survey questions were 
asked verbally, and by whom, or if the survey was answered in writing 
by the patient alone. As the study was not randomized and the patients' 
responses were not anonymous, we question if there may have been 
resulting response bias, or interviewer bias that would impact our 
ability to draw meaningful conclusions about a subjective measurement 
of improved quality of life. In addition, we note that the study 
utilized the Delcath Hepatic CHEMOSAT[supreg] Delivery System for 
Melphalan components as part of the treatment, and it is unclear if the 
technologies used in the study are the same as HEPZATOTM 
KIT, or what differences may exist between the technologies. We would 
be interested in information about any differences between Delcath's 
HEPZATOTM KIT and the technologies used in this study for 
PIHP with Melphalan.
    We are inviting public comments on whether HEPZATOTM KIT 
meets the substantial clinical improvement criterion.
    We did not receive any written comments in response to the New 
Technology Town Hall meeting notice published in the Federal Register 
regarding the substantial clinical improvement criterion for 
HEPZATOTM KIT.
g. LantidraTM (donislecel-jujn (Allogeneic Pancreatic Islet 
Cellular Suspension for Hepatic Portal Vein Infusion))
    CellTrans Inc. submitted an application for new technology add-on 
payments for LantidraTM for FY 2025. According to the 
applicant, LantidraTM is an allogeneic pancreatic islet 
cellular therapy indicated for the treatment of adults with Type 1 
diabetes who are unable to approach target hemoglobin A1c (HbA1c) 
because of repeated episodes of severe hypoglycemia despite intensive 
diabetes management and education. Per the applicant, 
LantidraTM is used in conjunction with concomitant 
immunosuppression. The applicant asserted that the route of 
administration for LantidraTM is infusion into the hepatic 
portal vein only. The applicant noted that following transplant, the 
patient is monitored for graft function and safety issues, including 
potential adverse reactions due to immunosuppression. The applicant 
stated that the primary mechanism of action for LantidraTM 
is the secretion of insulin by the beta cells within the infused 
allogeneic islet of Langerhans, which are responsible for regulating 
blood glucose levels in response to glucose stimulation.
    Please refer to the online application posting for 
LantidraTM, available at https://mearis.cms.gov/public/publications/ntap/NTP231017H5N2T, for additional detail describing the 
technology and the disease treated by the technology.
    With respect to the newness criterion, according to the applicant, 
LantidraTM was granted approval for a Biologics License 
Application (BLA) from FDA on June 28, 2023, for the treatment of 
adults with Type 1 diabetes who are unable to approach target HbA1c 
because of current repeated episodes of severe hypoglycemia despite 
intensive diabetes management and education. According to the 
applicant, the technology was commercially available on January 8, 
2024. The applicant stated that the approved manufacturing site for 
LantidraTM is at the University of Illinois (UI) Health, UI 
in Chicago and time was needed to transfer islet cell transplant 
clinical protocols to the UI Health transplant division.
    We note that under national coverage determination (NCD) 260.3.1 
Islet Cell Transplantation in the Context of a Clinical Trial, Medicare 
will pay for the routine costs, as well as transplantation and 
appropriate related items and services, for Medicare beneficiaries 
participating in a National Institutes of Health (NIH)-sponsored 
clinical trial(s). Specifically, Medicare will cover transplantation of 
pancreatic islet cells, the insulin producing cells of the pancreas. 
Coverage may include the costs of acquisition and delivery of the 
pancreatic islet cells, as well as clinically necessary inpatient and 
outpatient medical care and immunosuppressants. Because 
LantidraTM may be covered by Medicare when it is used in the 
setting of a clinical trial, we will evaluate whether 
LantidraTM is eligible for new technology add-on payments 
for FY 2025. We note that any payment made under the Medicare program 
for services provided to a beneficiary would be contingent on CMS' 
coverage of the item, and any restrictions on the coverage would apply.
    The applicant stated that the recommended minimum dose is 5,000 
equivalent islet number (EIN)/kg for the initial infusion, and 4,500 
EIN/kg for subsequent infusion(s) in the same recipient. The maximum 
dose per infusion is dictated by the estimated tissue volume, which 
should not exceed 10 cc per infusion, and the total EIN present in the 
infusion bag (up to a maximum of 1 x 10[supcaret]6 EIN per bag). A 
second infusion may be performed if the patient does not achieve 
independence from exogenous insulin within 1-year post-infusion or 
within 1-year after losing independence from exogenous insulin after a 
previous infusion. A third infusion may be performed using the same 
criteria as for the second infusion.
    According to the applicant, there are currently no ICD-10-PCS 
procedure codes to distinctly identify LantidraTM. We note 
that the applicant submitted a request for approval for a unique ICD-
10-PCS procedure code for LantidraTM beginning in FY 2025.
    As previously discussed, if a technology meets all three of the 
substantial similarity criteria under the newness criterion, it would 
be considered substantially similar to an existing technology and would 
not be considered new for the purpose of new technology add-on 
payments.
    With respect to the substantial similarity criteria, the applicant 
asserted that LantidraTM has not been assigned to the same 
MS-DRG when compared to an existing technology to achieve a therapeutic 
outcome. The following table summarizes the applicant's assertions 
regarding the substantial similarity criteria. Please see the online 
application posting for LantidraTM for the applicant's 
complete statements in support of its assertion that 
LantidraTM

[[Page 36067]]

is not substantially similar to other currently available technologies.
[GRAPHIC] [TIFF OMITTED] TP02MY24.102

    We are inviting public comments on whether LantidraTM is 
substantially similar to existing technologies and whether 
LantidraTM meets the newness criterion.
    With respect to the cost criterion, the applicant included the two 
most recent patient cases with charges of LantidraTM billed 
by a hospital that administered the technology, based on that 
hospital's billing data file on the undiscounted costs. The applicant 
stated that it attempted to identify potential cases representing 
patients who may be eligible for LantidraTM by searching the 
FY 2022 MedPAR and the 100 percent sample FY 2022 Standard Analytical 
Files (SAF) for cases reporting ICD-10-CM/PCS codes and MS-DRGs codes 
that were relevant to the FDA approved indication and administration of 
LantidraTM, however, it could not confirm if cost data from 
the two most recent patient cases were included in the FY 2022 MedPAR 
or SAF. As a result, the applicant provided the charges billed by the 
hospital for these two cases. The applicant stated that the MS-DRG 
coded for the two cases was MS-DRG 639 (Diabetes without CC/MCC). The 
applicant followed the order of operations described in the following 
table and calculated a final inflated average case-weighted 
standardized charge per case of $374,547, which exceeded the average 
case-weighted threshold amount of $32,311. Because the final inflated 
average case-weighted standardized charge per case exceeded the average 
case-weighted threshold amount, the applicant asserted that 
LantidraTM meets the cost criterion.
[GRAPHIC] [TIFF OMITTED] TP02MY24.103

    We note the following concerns regarding the cost criterion. We 
note that the applicant did not remove any charges or indirect charges 
related to prior technology without providing further details. We are 
interested in

[[Page 36068]]

additional information regarding whether LantidraTM would 
replace any prior technology. We are also interested in how the 
applicant estimated an inflation factor of 10.00 percent to apply to 
the standardized charges. With respect to the cases included in the 
cost analysis, we note that the applicant limited the cost analysis to 
the two most recent patient cases with charges of LantidraTM 
billed by the hospital, which the applicant asserted were the best 
available data for the FY 2022 cost analysis. We note the MS-DRG coded 
for these two cases was MS-DRG 639 (Diabetes without CC/MCC). We are 
interested in information as to whether cases in other MS-DRGs would be 
potentially eligible for LantidraTM and if these cases 
should also be included in the cost analysis by using appropriate 
inclusion/exclusion criteria based on reporting of ICD-10-CM/PCS codes.
    We are inviting public comments on whether LantidraTM 
meets the cost criterion.
    With regard to the substantial clinical improvement criterion, the 
applicant asserted that LantidraTM represents a substantial 
clinical improvement over existing technologies. The applicant asserted 
that patients with the indication of Type 1 diabetes characterized by 
hypoglycemic unawareness are at risk of severe hypoglycemia, 
complications, and death, if untreated. According to the applicant, 
when intensive insulin therapy is not sufficient for addressing 
symptoms of severe hypoglycemia, LantidraTM infusion into 
the hepatic portal vein offers a safe and effective minimally invasive 
alternative with proven clinical outcomes, less complications, and 
similar overall costs to that of whole pancreas transplantation. The 
applicant also asserted that LantidraTM provides a treatment 
option for patients unresponsive to, or ineligible for, currently 
available treatments because whole pancreas transplant, a currently 
available treatment, is associated with greater surgical and post-
procedural risk than pancreatic islet transplantation. Additionally, 
the applicant asserted that due to procedural risks, some patients may 
not be appropriate surgical candidates for whole pancreas 
transplantation.\66\ The applicant provided two patient testimonials, 
one study combining results of a Phase 1/2 and a Phase 3 clinical study 
to support these claims, as well as one background article.\67\ The 
following table summarizes the applicant's assertions regarding the 
substantial clinical improvement criterion. Please see the online 
posting for LantidraTM for the applicant's complete 
statements regarding the substantial clinical improvement criterion and 
the supporting evidence provided.

BILLING CODE 4120-01-C
    After review of the information provided by the applicant, we have 
the following concerns regarding whether LantidraTM meets 
the substantial clinical improvement criterion. We are interested in 
evidence on clinical outcomes based on comparison of 
LantidraTM with currently available treatments, including 
whole pancreatic transplant or recent advances in glucose monitoring 
and insulin delivery systems that are FDA-approved. We also note that 
according to the summary of the long-term six-year follow-up of 
patients from the LantidraTM clinical trials,\68\ the number 
of evaluable patients was reduced from 30 at the baseline to 12 at year 
6. We question whether the small number would impact the reliability of 
the conclusions about insulin independence and reduction in severe 
hypoglycemic events. Regarding the applicant's claim that 
LantidraTM patients achieved insulin independence, improved 
HbA1c endpoints, had fewer hypoglycemia episodes, and experienced 
improved quality of life, the applicant stated that the Phase 1/2 and 3 
trials had over 10 years of extended follow-up, but specific results on 
long-term efficacy appear to be provided only up to 6 years post- the 
last transplant.\69\ We would be interested in learning about available 
results from any longer-term follow-up. In addition, we would be 
interested in data demonstrating that LantidraTM results in 
improved clinical outcomes like reduced mortality to support an 
assessment of whether LantidraTM represents a substantial 
clinical improvement.

h. AMTAGVITM (lifileucel)
    Iovance Biotherapeutics, Inc. submitted an application for new 
technology add-on payments for AMTAGVITM (lifileucel) for FY 
2025. According to the applicant, AMTAGVITM is an one-time, 
single-dose autologous tumor-infiltrating lymphocyte (TIL) 
immunotherapy for the treatment of advanced (unresectable or 
metastatic) melanoma comprised of a suspension of TIL for intravenous 
infusion. We note that Iovance Biotherapeutics submitted an application 
for new technology add-on payments for AMTAGVITM for FY 2022 
under the name lifileucel, as summarized in the FY 2022 IPPS/LTCH PPS 
proposed rule (86 FR 25272 through 25282) but withdrew the application 
prior to the issuance of the FY 2022 IPPS/LTCH PPS final rule (86 FR 
44979). We also note that the applicant submitted an application for 
AMTAGVITM for FY 2023 under the name lifileucel, as 
summarized in the FY 2023 IPPS/LTCH PPS proposed rule (87 FR 28244 
through 28257), that it withdrew prior to the issuance of the FY 2023 
IPPS/LTCH PPS final rule (87 FR 48920).
    Please refer to the online application posting for 
AMTAGVITM, available at https://mearis.cms.gov/public/publications/ntap/NTP231012V8Y9J, for additional detail describing the 
technology and the treatment of unresectable or metastatic melanoma.
    With respect to the newness criterion, according to the applicant, 
AMTAGVITM was granted Biologics License Application (BLA) 
approval from FDA on February 16, 2024 for treatment of adult patients 
with unresectable or metastatic melanoma previously treated with a 
programmed cell death protein 1 (PD-1) blocking antibody, and if B-raf 
proto-oncogene (BRAF) V600 mutation positive, a BRAF inhibitor with or 
without a mitogen-activated extracellular signal-regulated kinase (MEK) 
inhibitor. The applicant stated that AMTAGVITM has received 
Regenerative Medicine Advanced Therapy (RMAT), Orphan Drug, and Fast 
Track designations from FDA for the treatment of advanced melanoma. 
According to the applicant, AMTAGVITM is expected to be 
commercially available within 30-40 days post-FDA approval due to the 
need for the physician to prescribe AMTAGVITM, the treatment 
center to receive approval from the patient's insurer and to schedule 
and surgically resect the patient's tumor tissue, the 22-day TIL 
manufacturing process, and shipment/invoicing of AMTAGVITM 
to the treatment center for patient administration. We are interested 
in additional information regarding the delay in the technology's 
market availability, as it seems that the technology would need to be 
available for sale before a physician would be able to prescribe 
AMTAGVITM.
    According to the applicant, AMTAGVITM is provided as a 
single dose for infusion containing a suspension of TIL in up to four 
patient-specific intravenous (IV) infusion bag(s), with each dose 
containing 7.5 x 10[supcaret]9 to 72 x 10[supcaret]9 viable cells. The 
applicant further noted that there is a lymphodepleting regimen 
administered before infusion of AMTAGVITM, and, post-
AMTAGVITM infusion, an interleukin 2 (IL-2) infusion at 
600,000 IU/kg is administered every 8 to 12 hours, for up to a maximum 
of 6 doses, to support cell expansion in vivo.
    The applicant stated that effective October 1, 2022, the following 
ICD-10-PCS codes may be used to uniquely describe procedures involving 
the use of AMTAGVITM: XW033L7 (Introduction of lifileucel 
immunotherapy into peripheral vein, percutaneous approach, new 
technology group 7), and XW043L7 (Introduction of lifileucel 
immunotherapy into central vein, percutaneous approach, new technology 
group 7). The applicant stated that all diagnosis codes under the 
category C43 (Malignant melanoma of skin) may be used to currently 
identify the indication for AMTAGVITM under the ICD-10-CM 
coding system.
    As previously discussed, if a technology meets all three of the 
substantial similarity criteria under the newness criterion, it would 
be considered substantially similar to an existing technology and would 
not be considered ``new'' for the purpose of new technology add-on 
payments.
    With respect to the substantial similarity criteria, the applicant 
asserted that AMTAGVITM is not substantially similar to 
other currently available technologies because TIL immunotherapy with 
AMTAGVITM has a novel and unique mechanism of action which 
delivers a highly customized, personalized, and targeted, single-
infusion treatment for advanced melanoma, and AMTAGVITM is 
the first and only TIL immunotherapy approved for the treatment of 
advanced (unresectable or metastatic) melanoma, and that therefore, the 
technology meets the newness criterion. The following table summarizes 
the applicant's assertions regarding the substantial similarity 
criteria. Please see the online application posting for 
AMTAGVITM for the applicant's complete statements in support 
of its assertion that AMTAGVITM is not substantially similar 
to other currently available technologies.

    We are inviting public comments on whether AMTAGVITM is 
substantially similar to existing technologies and whether 
AMTAGVITM meets the newness criterion.
    With respect to the cost criterion, the applicant provided multiple 
analyses to demonstrate that it meets the cost criterion. For each 
analysis, the applicant searched the FY 2022 MedPAR file using 
different combinations of ICD-10-CM codes, ICD-10-PCS codes, and/or 
inpatient length-of-stay (LOS) of 10 or more days. The applicant 
explained that it used different combinations to demonstrate four 
different cohorts that may be eligible for the technology. According to 
the applicant, eligible cases for AMTAGVITM will be mapped 
to Pre-MDC MS-DRG 018 (Chimeric Antigen Receptor (CAR) T-cell and Other 
Immunotherapies). For each analysis, the applicant used the FY 2025 new 
technology add-on payments threshold for Pre-MDC MS-DRG 018 for all 
identified cases. Each analysis followed the order of operations 
described in the table later in this section.
    For the first analysis, the applicant searched for potential cases 
for the following combination of ICD-10-CM diagnosis/procedure codes: 
any melanoma and metastasis diagnosis codes and any cytokine 
interleukin-2 (IL-2) or chemotherapy procedure codes. Please see the 
online posting for AMTAGVITM for the complete list of codes 
provided by the applicant. The applicant used the inclusion/exclusion 
criteria described in the following table. Under this analysis, the 
applicant identified 176 claims mapping to 16 MS-DRGs, with each MS-DRG 
representing 6.3 percent of identified cases. The applicant calculated 
a final inflated average case-weighted standardized charge per case of 
$2,150,682, which exceeded the average case-weighted threshold amount 
of $1,374,450.
    For the second analysis, the applicant searched for potential cases 
for the following ICD-10-CM diagnosis/procedure codes in combination 
with an inpatient LOS of 10 or more days: any melanoma and metastasis 
diagnosis codes and any cytokine interleukin-2 (IL-2) or chemotherapy 
procedure codes. Please see the online posting for AMTAGVITM 
for the complete list of codes provided by the applicant. The applicant 
used the inclusion/exclusion criteria described in the following table. 
Under this analysis, the applicant identified 77 claims mapping to 
seven MS-DRGs, with each MS-DRG representing 14.3 percent of identified 
cases. The applicant calculated a final inflated average case-weighted 
standardized charge per case of $2,207,367, which exceeded the average 
case-weighted threshold amount of $1,374,450.
    For the third analysis, the applicant searched for potential cases 
for the following combination of ICD-10-CM diagnosis/procedure codes: a 
code describing primary or admitting diagnosis of melanoma and a 
metastasis diagnosis code. Please see the online posting for 
AMTAGVITM for the complete list of codes provided by the 
applicant. The applicant used the inclusion/exclusion criteria 
described in the following table. Under this analysis, the applicant 
identified 735 claims mapping to 64 MS-DRGs, with each MS-DRG 
representing 3.4 percent to 1.5 percent of identified cases. The 
applicant calculated a final inflated average case-weighted 
standardized charge per case of $2,017,903, which exceeded the average 
case-weighted threshold amount of $1,374,450.
    For the fourth analysis, the applicant searched for potential cases 
for the following combination of ICD-10-CM diagnosis/procedure codes: a 
code describing any diagnosis of melanoma and a metastasis diagnosis 
code. Please see the online posting for AMTAGVITM

[[Page 36072]]

for the complete list of codes provided by the applicant. The applicant 
used the inclusion/exclusion criteria described in the following table. 
Under this analysis, the applicant identified 6,648 claims mapping to 
358 MS-DRGs, each MS-DRG representing 0.2 percent to 6.7 percent of 
identified cases. The applicant calculated a final inflated average 
case-weighted standardized charge per case of $2,018,905, which 
exceeded the average case-weighted threshold amount of $1,374,450.
    Because the final inflated average case-weighted standardized 
charge per case exceeded the average case-weighted threshold amount in 
all scenarios, the applicant asserted that AMTAGVITM meets 
the cost criterion.

    With regard to the substantial clinical improvement criterion, the 
applicant asserted that AMTAGVITM represents a substantial 
clinical improvement over existing technologies because the efficacy 
and safety profile of the single infusion of AMTAGVITM TIL 
immunotherapy addresses an important unmet need in the advanced 
(unresectable or metastatic) melanoma population who lack effective or 
approved treatment options after being previously treated with ICI 
therapy. The applicant asserts that the clinically meaningful and 
durable activity of AMTAGVITM represents substantial 
clinical improvement over published outcomes for chemotherapy. The 
applicant provided four studies to support these claims, as well as 22 
background articles about treatments for advanced melanoma.\76\

    After review of the information provided by the applicant, we have 
the following concerns regarding whether AMTAGVITM meets the 
substantial clinical improvement criterion.
    In support of its application, the applicant provided data from the 
C-144-01 study, an ongoing phase two multicenter study (NCT02360579) to 
assess the efficacy and safety of autologous TIL in patients with stage 
IIIc-IV metastatic melanoma, which consisted of: Cohort 1 (n = 30 
generation 1 no-cryopreserved TIL product); Cohort 2 (n = 66 generation 
2 cryopreserved TIL product); Cohort 3 (a sub-sample of n = 10 from 
Cohorts 1, 2, and 4); and Cohort 4 (n = 75 generation 2 cryopreserved 
TIL product). In regard to the sample studied (Cohorts 2 & 4 combined) 
by Chesney et al. (2022),\77\ similar to concerns raised in the FY 2022 
IPPS/LTCH PPS proposed rule (86 FR 25281), we continue to question the 
appropriateness of combining Cohorts 2 and 4 together. Furthermore, 
similar to concerns raised in the FY 2023 IPPS/LTCH PPS proposed rule 
(87 FR 28256 through 28257), we note that in the study of Chesney et 
al. (2022), 54 percent of the sample size included males with a median 
age of 56; data on race, ethnicity, and other demographics are not 
presented. Given that the average age of Medicare beneficiaries is 
substantially older, and that Medicare beneficiaries often have 
multiple comorbidities, we question whether the sample evaluated is 
appropriately representative of the Medicare population and whether 
this sample has a disease burden similar to that seen in Medicare 
beneficiaries.\78,79,80\ Thus, similar to concerns raised in the FY 
2023 IPPS/LTCH PPS proposed rule (87

[[Page 36076]]

FR 28256 through 28257), we are concerned that the findings may not be 
generalizable to Medicare beneficiaries. Furthermore, as discussed in 
the FY 2023 IPPS/LTCH PPS proposed rule (87 FR 28256), we continue to 
question whether the patient sample evaluated in the Sarnaik et al. 
(2021) \81\ study is appropriately representative of the Medicare 
population and whether this sample has a disease burden similar to that 
seen in Medicare beneficiaries.

---------------------------------------------------------------------------

    Second, similar to concerns raised in the FY 2022 IPPS/LTCH PPS 
proposed rule (86 FR 25279 through 25282) and the FY 2023 IPPS/LTCH PPS 
proposed rule (87 FR 28256 through 28257), we continue to note that 
while multiple background studies were provided in support of the 
applicant's claims for substantial clinical improvement, those that 
evaluate AMTAGVITM are based solely on the C-144-01 trial. 
The background studies focus primarily on describing the limitations of 
other therapies rather than supporting the role of 
AMTAGVITM, and no direct comparisons to other existing 
therapies such as targeted therapies with combination BRAF plus MEK 
inhibitors or nivolumab plus ipilimumab were provided. Therefore, we 
would be interested in additional information comparing 
AMTAGVITM to existing treatments (for example, evidence 
comparing AMTAGVITM phase two studies to the phase two 
studies of existing or approved treatments by using meta-analysis after 
systematic review, or evidence based on retrospective cohort studies of 
the relevant patients to assess whether AMTAGVITM had 
significantly different impact on any outcomes compared to existing or 
approved treatments).
    Third, similar to concerns raised in the FY 2022 IPPS/LTCH PPS 
proposed rule (86 FR 25279 through 25282), and the FY 2023 IPPS/LTCH 
PPS proposed rule (87 FR 28256 through 28257), we note that the Chesney 
et al. (2022) \82\ study uses a surrogate endpoint, ORR, which combines 
the results of complete and partial responders; we question whether 
this correlates to improvement in clinical outcomes such as overall 
survival (OS).

---------------------------------------------------------------------------

    Finally, similar to concerns raised in the FY 2023 IPPS/LTCH PPS 
proposed rule (87 FR 28256 through 28257), we note that according to 
the applicant, high-dose IL-2 has been used to treat metastatic 
melanoma in the past and is given as a post-treatment to 
AMTAGVITM. According to the applicant, the occurrence of 
grade 3 and 4 treatment-emergent adverse events (TEAEs) was early and 
consistent with the lymphodepletion regimen (NMA-LD) and known profile 
of IL-2. If AMTAGVITM is always given in conjunction with 
the pre- and post-treatments, we question how it is possible to 
determine the cause of the TEAEs which are categorized as severe based 
on the Common Terminology Criteria for Adverse Events v4.03. We 
continue to question whether the effect seen in C-144-01 is due to 
AMTAGVITM itself or due to other factors such as the use of 
IL-2, general changes in medical practice over time, and the specific 
sample identified for the trial at hand.
    We are inviting public comments on whether AMTAGVITM 
meets the substantial clinical improvement criterion.
    We did not receive any written comments in response to the New 
Technology Town Hall meeting notice published in the Federal Register 
regarding the substantial clinical improvement criterion for 
AMTAGVITM.
i. LyfgeniaTM (lovotibeglogene autotemcel)
    Bluebird bio, Inc. submitted an application for new technology add-
on payments for Lyfgenia\TM\ (lovotibeglogene autotemcel) for FY 2025. 
According to the applicant, Lyfgenia\TM\ is an autologous hematopoietic 
stem cell-based gene therapy indicated for the treatment of patients 12 
years of age or older with sickle cell disease (SCD) and a history of 
vaso-occlusive events (VOE). Lyfgenia\TM\, administered as a single-
dose intravenous infusion, consists of an autologous cluster of 
differentiation 34+ (CD34+) cell-enriched population from patients with 
SCD that contains hematopoietic stem cells (HSCs) transduced with BB305 
lentiviral vector (LVV) encoding the [beta]-globin gene 
([beta]A-T87Q-globin gene), suspended in a cryopreservation 
solution. The applicant explained that Lyfgenia\TM\ is designed to add 
functional copies of a modified form of the [beta]A-T87Q-
globin gene into a patient's own HSCs, which allows their red blood 
cells to produce an anti-sickling adult hemoglobin (HbA\T87Q\), to 
reduce or eliminate downstream complications of SCD.
    Please refer to the online application posting for Lyfgenia\TM\, 
available at https://mearis.cms.gov/public/publications/ntap/NTP231013X3AK8, for additional detail describing the technology and the 
disease treated by the technology.
    With respect to the newness criterion, according to the applicant, 
Lyfgenia\TM\ was granted Biologics License Application (BLA) approval 
from FDA on December 8, 2023, for the treatment of patients 12 years of 
age or older with SCD and a history of VOEs. The applicant stated that 
it anticipates that LyfgeniaTM will become available for 
sale on April 16, 2024 and that the first commercial claim for 
Lyfgenia\TM\ will occur within approximately 130 days post-FDA approval 
to allow for the one-time activity to commercially qualify the contract 
manufacturer organization (CMO), followed by apheresis of the first 
patient at the qualified treatment center (QTC), where the personalized 
starting material will be shipped to the CMO for drug product 
manufacturing, release testing, and shipment of final product to the 
QTC for the one-time infusion. We are interested in additional 
information regarding the delay in the technology's market 
availability, as it appears that the technology would need to be 
available for sale prior to the enrollment of the first patient at the 
QTC. According to the applicant, Lyfgenia\TM\ is provided in infusion 
bags containing 1.7 to 20x10\6\ cells/mL (1.4 to 20 x 10\6\ CD34+ 
cells/mL) in approximately 20 mL of solution and is supplied in one to 
four infusion bags. Per the applicant, the minimum dose is 3.0 x 10\6\ 
CD34+ cells/kg patient weight.
    According to the applicant, as of October 1, 2023, there are 
currently two ICD-10-PCS procedure codes to distinctly identify the 
intravenous administration of Lyfgenia\TM\: XW133H9 (Transfusion of 
lovotibeglogene autotemcel into central vein, percutaneous approach, 
new technology group 9) and XW143H9 (Transfusion of lovotibeglogene 
autotemcel into peripheral vein, percutaneous approach, new technology 
group 9). The applicant provided a list of diagnosis codes that may be 
used to currently identify the indication for Lyfgenia\TM\ under the 
ICD-10-CM coding system. Please refer to the online application posting 
for the complete list of ICD-10-CM codes provided by the applicant.
    As previously discussed, if a technology meets all three of the 
substantial similarity criteria under the newness criterion, it would 
be considered substantially similar to an existing technology and would 
not be considered ``new'' for the purpose of new technology add-on 
payments.
    With respect to the substantial similarity criteria, the applicant 
asserted that Lyfgenia\TM\ is not substantially

[[Page 36077]]

similar to other currently available technologies, because Lyfgenia\TM\ 
has a distinct mechanism of action, which converts SCD at the genetic, 
cellular, and physiologic level to a non-sickling phenotype through the 
expression of the gene therapy-derived antisickling 
[beta]A-T87Q-globin gene, and that therefore, the technology 
meets the newness criterion. Additionally, the applicant stated 
LyfgeniaTM is not substantially similar to other currently 
available therapeutic approaches indicated for SCD or to any drug 
therapy assigned to any MS-DRG in the 2022 MedPAR data.
    The following table summarizes the applicant's assertions regarding 
the substantial similarity criteria. Please see the online application 
posting for Lyfgenia\TM\ for the applicant's complete statements in 
support of its assertion that Lyfgenia\TM\ is not substantially similar

    We note that Lyfgenia\TM\ may have the same or similar mechanism of 
action to Casgevy\TM\, for which we also received an application for 
new technology add-

on payments for FY 2025. Lyfgenia\TM\ and Casgevy\TM\ are both gene 
therapies using modified autologous CD34+ hematopoietic stem and 
progenitor cell (HSPC) therapies administered via stem cell 
transplantation for the treatment of SCD. Both technologies are 
autologous, ex-vivo modified hematopoietic stem-cell biological 
products. As previously discussed, CasgevyTM was approved by 
FDA for this indication on December 8, 2023. For these technologies, 
patients are required to undergo CD34+ HSPC mobilization followed by 
apheresis to extract CD34+ HSPCs for manufacturing and then 
myeloablative conditioning using busulfan to deplete the patient's bone 
marrow in preparation for the technologies' modified stem cells to 
engraft to the bone marrow. Once engraftment occurs for both 
technologies, the patient's cells start to produce a different form of 
hemoglobin to reduce the amount of sickling hemoglobin. Further, both 
technologies appear to map to the same MS-DRGs, MS-DRG 016 (Autologous 
Bone Marrow Transplant with CC/MCC) and 017 (Autologous Bone Marrow 
Transplant without CC/MCC), and to treat the same or similar disease 
(sickle cell disease) in the same or similar patient population 
(patients 12 years of age and older who have a history of vaso-
occlusive events). Accordingly, as it appears that Lyfgenia\TM\ and 
Casgevy\TM\ may use the same or similar mechanism of action to achieve 
a therapeutic outcome (that is, to reduce the amount of sickling 
hemoglobin to reduce and prevent VOEs associated with SCD), would be 
assigned to the same MS-DRG, and treat the same or similar patient 
population and disease, we believe that these technologies may be 
substantially similar to each other such that they should be considered 
as a single application for purposes of new technology add-on payments. 
We note that if we determine that this technology is substantially 
similar to CasgevyTM, we believe the newness period would 
begin on December 8, 2023, the date both LyfgeniaTM and 
CasgevyTM received FDA approval for SCD. We are interested 
in information on how these two technologies may differ from each other 
with respect to the substantial similarity criteria and newness 
criterion, to inform our analysis of whether LyfgeniaTM and 
CasgevyTM are substantially similar to each other and 
therefore should be considered as a single application for purposes of 
new technology add-on payments.
    We are inviting public comment on whether LyfgeniaTM 
meets the newness criterion, including whether LyfgeniaTM is 
substantially similar to CasgevyTM and whether these 
technologies should be evaluated as a single technology for purposes of 
new technology add-on payments.
    With respect to the cost criterion, the applicant provided multiple 
analyses to demonstrate that it meets the cost criterion. For each 
analysis, the applicant searched the FY 2022 MedPAR using different 
ICD-10-CM codes to identify potential cases representing patients who 
may be eligible for Lyfgenia\TM\. Per the applicant, Lyfgenia\TM\ is 
intended for patients who have not already undergone Allogeneic Bone 
Marrow Transplant or Autologous Bone Marrow Transplant. The applicant 
explained that it used different ICD-10-CM codes to demonstrate 
different cohorts of SCD patients that may be eligible for the 
technology.
    According to the applicant, eligible cases for Lyfgenia\TM\ will be 
mapped to either Pre-MDC MS-DRG 016 (Autologous Bone Marrow Transplant 
with CC/MCC) or 017 (Autologous Bone Marrow Transplant without CC/MCC). 
For each cohort, the applicant performed two sets of analyses using 
either the FY 2025 new technology add-on payments threshold for Pre-MDC 
MS-DRG 016 or Pre-MDC MS-DRG 017 for all identified cases. We note that 
the FY 2025 new technology add-on payments thresholds for both Pre-MDC 
MS-DRG 016 and Pre-MDC MS-DRG 017 are $182,491. Each analysis followed 
the order of operations described in the table later in this section.
    For the primary cohort, the applicant searched for an appropriate 
group of patients with any ICD-10-CM diagnosis code for SCD with 
crisis. Please see the online posting for LyfgeniaTM for the 
complete list of ICD-10-CM codes provided by the applicant. The 
applicant used the inclusion/exclusion criteria described in the 
following table. Under this analysis, the applicant identified 12,357 
claims mapping to 167 MS-DRGs, including MS-DRGs 811 and 812 (Red Blood 
Cell Disorders with MCC and without MCC, respectively) representing 
76.0 percent of total identified cases. The applicant calculated a 
final inflated average case-weighted standardized charge per case of 
$11,677,887, which exceeded the average case-weighted threshold amount 
of $182,491.
    For the sensitivity 1 cohort, the applicant searched for a narrower 
cohort of patients with the admitting or primary ICD-10-CM diagnosis 
codes of Hemoglobin-SS (Hb-SS) SCD with crisis for the most common 
genotype of SCD. Please see the online posting for 
LyfgeniaTM for a complete list of ICD-10-CM codes provided 
by the applicant. The applicant used the inclusion/exclusion criteria 
described in the following table. Under this analysis, the applicant 
identified 10,987 claims mapping to 160 MS-DRGs, including MS-DRGs 811 
and 812 (Red Blood Cell Disorders with and without MCC, respectively) 
representing 75.1 percent of total identified cases. The applicant 
calculated a final inflated average case-weighted standardized charge 
per case of $11,680,025, which exceeded the average case-weighted 
threshold amount of $182,491.
    For the sensitivity 2 cohort, the applicant searched for a broader 
cohort of patients with the primary or secondary ICD-10-CM diagnosis 
codes for SCD with or without crisis. Please see the online posting for 
LyfgeniaTM for a complete list of ICD-10-CM codes provided 
by the applicant. The applicant used the inclusion/exclusion criteria 
described in the following table. Under this analysis, the applicant 
identified 17,120 claims mapping to 453 MS-DRGs, including MS-DRGs 811 
and 812 (Red Blood Cell Disorders with and without MCC, respectively) 
representing 56.3 percent of total identified cases. The applicant 
calculated a final inflated average case-weighted standardized charge 
per case of $11,681,718, which exceeded the average case-weighted 
threshold amount of $182,491.
    Because the final inflated average case-weighted standardized 
charge per case exceeded the average case-weighted threshold amount in 
all scenarios, the applicant maintained that Lyfgenia\TM\ meets the 
cost criterion.

    We are inviting public comments on whether Lyfgenia\TM\ meets the 
cost criterion. With regard to the substantial clinical improvement 
criterion, the applicant asserted that Lyfgenia\TM\ represents a 
substantial clinical improvement over existing technologies, because 
Lyfgenia\TM\ is a one-time administration gene therapy that uniquely 
impacts the pathophysiology of SCD at the genetic level and offers the 
potential for stable, durable production of anti-sickling hemoglobin 
HbA\T87Q\, with approximately 85 percent of RBCs producing HbA\T87Q\, 
leading to complete resolution of severe VOEs in patients with SCD 
through 5.5 years of follow-up. The applicant asserted that for these 
reasons Lyfgenia\TM\ is a much-needed treatment option for a patient 
population ineligible for allo-HSCT or without a matched related donor 
and significantly improves health-related quality of life. The 
applicant provided seven studies on LyfgeniaTM to support 
these claims, as well as 22 background articles about SCD and its 
current treatments.\84\ The following table summarizes the applicant's 
assertions regarding the substantial clinical improvement criterion. 
Please see the online posting for Lyfgenia\TM\ for the applicant's 
complete statements regarding the substantial clinical improvement 
criterion and the supporting evidence provided.

BILLING CODE 4120-01-C
    After review of the information provided by the applicant, we have 
the following concerns regarding whether Lyfgenia\TM\ meets the 
substantial clinical improvement criterion. With respect to the claim 
that Lyfgenia\TM\ presents an acceptable risk-benefit profile in terms 
of efficacy and safety for patients with SCD while allowing clinically 
meaningful improvements in HRQoL, the applicant stated the safety 
profile remains generally consistent with risk of autologous stem cell 
transplant, myeloablative conditioning, and underlying SCD. 
Additionally, the applicant mentions that serious treatment-emergent 
adverse events (TEAEs) of grade 3 or higher TEAEs were reported, but no 
cases of veno-occlusive liver disease, graft failure, or vector-
mediated replication competent lentivirus were reported. Per the 
applicant, three patients had adverse events attributed to 
Lyfgenia\TM\, including 2 events deemed possibly related and 1 event 
deemed definitely related, with all 3 resolving within 1 week of onset. 
We note that the applicant submitted one published article about Group 
C results, an interim analysis by Kanter et al. (2022) \85\ in which 
Lyfgenia\TM\'s safety and efficacy were evaluated in a nonrandomized, 
open-label, single-dose phase 1-2 clinical trial (HGB-206) where 35 
Group C patients had received LyfgeniaTM infusion. Group C 
was established after optimizing the treatment process in the initial 
cohorts, Groups A (7 patients) and B (2 patients). There was also a 
more stringent inclusion criterion for severe vaso-occlusive events 
before enrollment for Group C. The median follow-up was 17.3 months 
(range, 3.7-37.6) and 25 patients met both the inclusion criteria for 
vaso-occlusive events before enrollment and a minimum 6-month follow-up 
required for assessment of vaso-occlusive events. After receiving 
Lyfgenia\TM\, 12 patients (34 percent) had at least one serious adverse 
event; the most frequently reported were abdominal pain, drug 
withdrawal syndrome (opiate), nausea, and vomiting (6 percent each). 
The two events that were deemed to be possibly related to 
LyfgeniaTM were grade 2 leukopenia and grade 1 decreased 
diastolic blood pressure and the one event that was deemed to be 
definitely related was grade 2 febrile neutropenia. Although this 
evidence was provided to assert LyfgeniaTM improves clinical 
outcomes relative to previously available therapies, we note that the 
risk-benefit profile and HRQoL for LyfgeniaTM is not 
compared to existing therapies. We would be interested in additional 
information regarding the risk-benefit profile of LyfgeniaTM 
compared to existing therapies, including clarification regarding an 
acceptable risk-benefit profile for patients with SCD and whether 
Lyfgenia\TM\ fits this profile. We also question if the length of 
patient follow-up (median: 17.3 months, range: 3.7 to 37.6) would be 
sufficient to assess long-term safety outcomes.

---------------------------------------------------------------------------

    Finally, with respect to the applicant's assertion that 
LyfgeniaTM improves clinical outcomes by halting SCD 
progression, presenting an acceptable risk-benefit profile with 
clinically meaningful improvement in HRQoL, and results in complete 
resolution of sVOEs, we note that the applicant provided multiple 
sources of evidence that analyze the same phase 1-2 clinical study for 
LyfgeniaTM, HGB-206. We received an additional unpublished 
source \86\ that provided some data on the phase 3 HGB-210 trial and 
combined this with data from HGB-206 with a total of 34 patients being 
evaluable for efficacy and 47 for safety. The median age of these 47 
patients was 23 years. Due to the small study population and the median 
age of participants in the studies, we question if the safety and 
efficacy data from these studies would be generalizable to the Medicare 
population.

j. Quicktome Software Suite (Quicktome Neurological Visualization and 
Planning Tool)
    Omniscient Neurotechnology submitted an application for new 
technology add-on payments for Quicktome Software Suite for FY 2025. 
According to the applicant, Quicktome Software Suite is a cloud-based 
software that uses artificial intelligence (AI) tools and the 
scientific field of connectomics to analyze millions of data points 
derived from a patient's magnetic resonance imaging (MRI). Per the 
applicant, Quicktome Software Suite's proprietary Structural 
Connectivity Atlas (SCA) uses machine learning and

[[Page 36082]]

tractographic techniques to create highly specific and personalized 
maps of a patient's brain or connectome from a standard MRI scan, 
regardless of brain shape, size, or physical distortion. The applicant 
asserted that the SCA is combined with a key refinement algorithm which 
identifies the location of parcels based on the specific structural 
characteristics of an individual's brain. The applicant asserted that 
Quicktome Software Suite uses resting-state functional MRI (rs-fMRI) to 
unveil the brain's network architecture or functional connectome by 
mapping blood oxygen level dependent (BOLD) signal correlations across 
brain parcels. Per the applicant, using data from a structural or a 
functional MRI (fMRI) scan, Quicktome Software Suite's proprietary AI 
allows clinicians to quickly and accurately assess the structural 
layout (that is, the locations and integrity) or the functional 
connectivity (that is, how different brain regions are working 
together) of a patient's brain.
    Please refer to the online application posting for Quicktome 
Software Suite, available at https://mearis.cms.gov/public/publications/ntap/NTP23101722NQE, for additional detail describing the 
technology and the disease for which the technology is used.
    With respect to the newness criterion, according to the applicant, 
the Quicktome Software Suite received FDA 510(k) clearance on May 30, 
2023. Per the FDA-cleared indication, the Quicktome Software Suite is 
composed of a set of modules intended for the display of medical images 
and other healthcare data. It includes functions for image review, 
image manipulation, basic measurements, planning, 3D visualization (MPR 
reconstructions and 3D volume rendering), and the display of BOLD rs-
MRI scan studies. The FDA clearance for Quicktome Software Suite was 
based on substantial equivalence to the legally marketed predicate 
device, StealthViz Advanced Planning Application with Stealth Diffusion 
Tensor Imaging (DTI)TM Package (hereafter referred to as 
StealthVizTM), as both of these devices allow the import and 
export of DICOM images to a hospital picture archiving and 
communication system (PACS); contain a graphical user interface to 
conduct planning and visualization; display MRI anatomical images, as 
well as tractography constructed from Diffusion Weighted Images, in 2D 
and 3D views; register tractography and an atlas to the underlying 
anatomical images; allow adding, removing, and editing of objects 
(including automatically segmented and manually defined regions of 
interest); and are delivered as software on an off-the-shelf hardware 
platform.\87\ Prior to the FDA 510(k) clearance of Quicktome Software 
SuiteTM in 2023, the technology, under the trade name 
Quicktome, received FDA 510(k) clearance on March 9, 2021, based on 
substantial equivalence to StealthVizTM.\88\ 
StealthVizTM received FDA 510(k) clearance on May 16, 2008 
for use in two- and three-dimensional (2D and 3D) surgical planning and 
image review and analysis. According to the FDA 510(k) summary for 
StealthVizTM, it enables digital diagnostic and functional 
imaging datasets, reviewing and analyzing the data in various 2D and 3D 
presentation formats, performing image fusion of datasets, segmenting 
structures in the images with manual and automatic tools and converting 
them into 3D objects for display, and exporting results to other 
Medtronic Navigation planning applications, to a PACS or to Medtronic 
Navigation surgical navigation systems such as StealthStation System. 
According to the applicant, the Quicktome Software Suite was 
commercially available immediately after FDA clearance.

---------------------------------------------------------------------------

    According to the applicant, there are currently no ICD-10-PCS 
procedure codes to distinctly identify the Quicktome Software Suite. We 
note that the applicant submitted a request for approval for a unique 
ICD-10-PCS procedure code for the Quicktome Software Suite beginning in 
FY 2025. The applicant provided a list of diagnosis codes that may 
currently be used to identify the indication for Quicktome Software 
Suite under the ICD-10-CM coding system. Please refer to the online 
application posting for the complete list of ICD-10-CM codes provided 
by the applicant.
    As previously discussed, if a technology meets all three of the 
substantial similarity criteria under the newness criterion, it would 
be considered substantially similar to an existing technology and would 
not be considered new for the purpose of new technology add-on 
payments.
    With respect to the substantial similarity criteria, the applicant 
asserted that Quicktome Software Suite is not substantially similar to 
other currently available technologies because it is the first and only 
FDA-cleared platform to enable connectomic analysis at an individual 
level using machine learning and tractographic techniques to create 
personalized maps of the human brain. In addition, the applicant 
asserted that Quicktome Software Suite is the first cleared 
neurological planning tool to offer rs-fMRI capabilities. Per the 
applicant, Quicktome Software Suite eliminates the need for highly 
trained personnel, who may not be available at most institutions, and 
therefore, the technology meets the newness criterion. The applicant 
further asserted that current technologies that rely on task-based fMRI 
(tb-fMRI) can be problematic in brain tumor patients who may be 
cognitively impaired because they may be unable to perform required 
tasks. The following table summarizes the applicant's assertions 
regarding the substantial similarity criteria. Please see the online 
application posting for Quicktome Software Suite for the applicant's 
complete statements in support of its assertion that the Quicktome 
Software Suite is not substantially similar to other currently 
available technologies.

[[Page 36083]]

[GRAPHIC] [TIFF OMITTED] TP02MY24.114

    We note the following concerns regarding whether Quicktome Software 
Suite meets the newness criterion. With respect to the applicant's 
claim that Quicktome Software Suite does not use the same or similar 
mechanism of action as existing technologies to achieve a therapeutic 
outcome, we note that, according to the 510(k) application, it appears 
that the Quicktome Software Suite is equivalent to 
StealthVizTM, its predicate device. We are unclear how the 
Quicktome Software Suite's mechanism of action, which enables patient-
specific connectomic analysis for neurological planning, is different 
from that of StealthVizTM. We note that 
StealthVizTM received FDA 510(k) clearance on May 16, 2008 
for use in 2D/3D surgical planning and image review and analysis, and 
therefore is no longer considered new for purposes of new technology 
add-on payments. According to the applicant, Quicktome Software Suite 
is the first and only FDA-cleared platform to enable brain network 
mapping and analysis at an individual level and provides clinicians 
with information that was previously only available in a research 
setting. We would be interested in further information to support that 
the Quicktome Software Suite does not use the same or similar mechanism 
of action as StealthVizTM to achieve a therapeutic outcome, 
including information regarding capabilities of Quicktome Software 
Suite not found in StealthVizTM, and whether and how those 
capabilities are the result of a new mechanism of action.
    In addition, we note that there are several existing FDA-approved 
or cleared technologies (for example, StealthVizTM, 
Brainlab's Elements and iPlan products) that analyze fMRI and other 
medical imaging data to create 3-D maps of a patient's brain, including 
white matter tracts. Furthermore, while the applicant asserted that 
Quicktome Software Suite is the only FDA-cleared device that uses a rs-
fMRI, we question whether other FDA-cleared neurosurgical planning and 
visualization technologies integrate rs-fMRI, or if the analysis of rs-
fMRI for neurosurgical planning is a mechanism of action unique to 
Quicktome Software Suite. We would be interested in more information on 
the relevant current standard of care and technologies utilized for 
neurosurgical planning and how the mechanism of action of the Quicktome 
Software Suite compares to the mechanism of action of existing 
technologies and connectomics software.
    With respect to the third criterion, whether Quicktome Software 
Suite involves the treatment of the same or similar disease and patient 
population compared to existing technologies, we note that the 
applicant stated that the Quicktome Software Suite does not treat a new 
disease type or patient population, but does provide new information 
for the treatment of existing patient populations. However, the 
provision of new information for the treatment of existing patient 
populations does not mean that the technology treats a new disease type 
or patient population, and therefore, it is unclear what the basis is 
for the applicant's statement that the third criterion is not met. We 
would be interested in additional information to support whether and 
how Quicktome Software Suite may involve the treatment of a different 
type of disease or patient population.
    As discussed in the FY 2022 IPPS/LTCH PPS final rule (86 FR 44981), 
we also continue to be interested in public comments regarding issues 
related to determining newness for technologies that use AI, an 
algorithm, or software. Specifically, we are interested in public 
comment on how these technologies may be considered for the purpose of 
identifying a unique mechanism of action; how updates to AI, an 
algorithm, or software would affect an already approved technology or a 
competing technology; whether software changes for an already approved 
technology could be considered a new mechanism of action, and whether 
an improved algorithm by competing technologies would represent a 
unique mechanism of action if the outcome is the same as an already 
approved AI new technology.
    We are inviting public comments on whether Quicktome Software Suite 
is substantially similar to existing technologies and whether Quicktome 
Software Suite meets the newness criterion.
    With respect to the cost criterion, to identify potential cases 
representing patients who may be eligible for Quicktome Software Suite, 
the applicant searched 2020 Medicare Inpatient

[[Page 36084]]

Hospitals--by Provider and Service data.\89\ The applicant included all 
cases from the following MS-DRGs: 025 (Craniotomy and Endovascular 
Intracranial Procedures with MCC), 026 (Craniotomy and Endovascular 
Intracranial Procedures with CC), and 027 (Craniotomy and Endovascular 
Intracranial Procedures without CC/MCC). Using the inclusion/exclusion 
criteria described in the following table, the applicant identified 
28,401 cases mapping to these three craniotomy MS-DRGs, with 64 percent 
of the identified cases mapping to MS-DRG 025. The applicant followed 
the order of operations described in the following table and calculated 
a final inflated average case-weighted standardized charge per case of 
$179,317, which exceeded the average case-weighted threshold amount of 
$134,802. Because the final inflated average case-weighted standardized 
charge per case exceeded the average case-weighted threshold amount, 
the applicant asserted that Quicktome Software Suite meets the cost 
criterion.

[GRAPHIC] [TIFF OMITTED] TP02MY24.115

    We note the following concerns regarding the cost criterion. We 
note that the applicant limited its cost analysis to MS-DRGs 025, 026, 
and 027 because those three MS-DRGs represent brain tumor resection 
procedures, which are the first and most clearly established procedures 
for which the technology offers clinical utility. We are interested in 
information as to whether the technology would map to other MS-DRGs, 
such as 023 and 024 (Craniotomy with Major Device Implant or Acute 
Complex CNS PDX with MCC or Chemotherapy, or without MCC, 
respectively), or 054 and 055 (Nervous System Neoplasms with and 
without MCC, respectively), and if these MS-DRGs should also be 
included in the cost analysis. In addition, we question whether every 
case within MS-DRGs 025, 026, 027 would be eligible for the technology 
and whether there would be any appropriate inclusion/exclusion criteria 
by ICD-10-CM/PCS codes within these MS-DRGs to identify potential cases 
representing patients who may be eligible for Quicktome Software Suite.
    We are inviting public comments on whether Quicktome Software Suite 
meets the cost criterion.
    With regard to the substantial clinical improvement criterion, the 
applicant asserted that Quicktome Software Suite represents a 
substantial clinical improvement over existing technologies because 
Quicktome supports the visualization and brain mapping that improve 
clinical outcomes such as reducing the risk of an extended length of 
stay (LOS) and unplanned readmissions for craniotomy patients by 
reducing new postoperative neurological deficits that are caused by 
damage to brain networks or a patient's connectome. The applicant 
further asserted that Quicktome Software Suite is the first and only 
FDA-cleared platform to enable connectomic analysis at an individual 
level, enabling surgeons to visualize and avoid damaging these brain 
networks during surgery, thereby significantly improving clinical

[[Page 36085]]

outcomes relative to services or technologies previously available. The 
applicant submitted three published studies and one unpublished study 
evaluating the Quicktome Software Suite to support these claims, as 
well as four background articles about complications leading to 
unplanned readmissions after cranial surgery, factors associated with 
extended LOS in patients undergoing craniotomy for tumor resection, the 
association of incorporating fMRI in presurgical planning with 
mortality and morbidity in brain tumor patients, and the clinical 
importance of non-traditional, large-scale brain networks with respect 
to the potential adverse effects on patients when these networks are 
disrupted during surgery.\90\ We note that one of the articles 
submitted as a study using the technology, the Dadario and Sughrue 
(2022) \91\ study, should more appropriately be characterized as a 
background article because it does not directly assess the use of 
Quicktome Software Suite.

BILLING CODE 4120-01-C
    After our review of the information provided by the applicant, we 
have the following concerns regarding whether Quicktome Software Suite 
meets the substantial clinical improvement criterion.
    With respect to the applicant's claim that Quicktome Software Suite 
supports the visualization of brain networks and surgical planning to 
avoid damaging them during surgery, we are concerned that the evidence 
does not appear to demonstrate that the Quicktome Software Suite's 
visualization and brain mapping techniques improve clinical outcomes 
relative to services or technologies already available by avoiding or 
reducing damage to the brain networks during surgery. For example, the 
Shah et al. (2023) \92\ study

[[Page 36086]]

describes the use of connectomics in planning and guiding an awake 
craniotomy for a tumor impinging on the language area in a 31-year-old 
bilingual woman. The authors stated that Quicktome Software Suite was 
used to generate preoperative connectome imaging for the patient, which 
helped in assessing the risk of functional deficits, guiding surgical 
planning, directing intraoperative mapping stimulation, and providing 
insights into postoperative function. The authors further described how 
preoperative imaging demonstrated proximity of the tumor to 
parcellations of the language area, and how intraoperative awake 
language mapping was performed, revealing speech arrest and paraphasic 
errors at areas of the tumor boundary correlating to functional regions 
that explained these findings. However, we are concerned that the 
report is based on a single case, and we question whether these 
findings would be generalizable to the broader Medicare population. In 
addition, we note that the applicant did not provide evidence based on 
comparison of the use of Quicktome Software Suite technology with 
currently available cranial mapping software or tractography tools, and 
we would be interested in comparisons that assess the use of Quicktome 
Software Suite technology to improve these clinical outcomes relative 
to currently available technologies, such as StealthVizTM or 
Brainlab's Elements and iPlan products.

---------------------------------------------------------------------------

    In addition, we question whether the findings related to 
Quicktome's efficacy are generalizable to the Medicare population. 
Specifically, the Wu et al. (2023) \93\ study aimed to investigate the 
involvement of non-traditional brain networks in insulo-Sylvian gliomas 
and evaluate the potential of Quicktome Software Suite in optimizing 
surgical approaches to preserve cognitive function. The study included 
three parts. The first part involved a retrospective analysis of the 
location of insulo-Sylvian gliomas in 45 adult patients who underwent 
glioma surgery centered in the insular lobe. According to the research 
team, Quicktome showed that 98 percent of the tumors involved a non-
traditional eloquent brain network, which is associated with cognitive 
or neurological function. In part two, the research team prospectively 
collected neuropsychological data on seven patients to assess tumor-
network involvement with change in cognition. Using Quicktome, the 
research team found that all seven patients had a tumor involving a 
non-traditional eloquent brain network. Part three described how the 
research team used Quicktome Software Suite's network mapping 
capabilities to inform surgical decision-making and predict the 
preservation of cognitive function post-surgery for two prospective 
patients. We note that while Quicktome Software Suite was used to 
assist surgical decision-making in two patients, as previously 
discussed, we question whether these limited findings would be 
generalizable to the broader Medicare population, and we would be 
interested in comparisons between Quicktome Software Suite and other 
currently available technologies to improve these clinical outcomes.

---------------------------------------------------------------------------

    We also question whether the use of Quicktome Software Suite has a 
direct impact on significantly reducing neurological or cognitive 
deficits post-surgery. The applicant cited Morell et al. (2022),\94\ a 
retrospective, single-center study of 100 patients who underwent 
surgery for brain tumor resection. The research team used Quicktome 
Software Suite to map and evaluate the integrity of nine large-scale 
brain networks in these patients. According to the research team, 
Quicktome's analysis showed that for more than half of these patients, 
at least one of their brain networks were either affected during brain 
surgery or at risk of postsurgical deficits. Among those at risk of 
postsurgical deficits, their cortical regions or white matter fibers 
were either displaced by the mass effect of the tumor or damaged during 
surgery due to proximity to the tumor and/or planned transcortical 
trajectory. We note that the primary focus of the study was to 
retrospectively map large-scale brain networks in brain tumor patients 
using Quicktome Software Suite platform, and therefore does not appear 
to demonstrate that use of Quicktome Software Suite avoided damaging 
these networks during surgery.

    Similarly, we note that the applicant cited Hendricks et al. 
(n.d.),\95\ which retrospectively analyzed the outcomes of 346 adult 
patients who underwent resection of superficial cerebral cavernous 
malformations (CMs) from November 2008 through June 2021. We note that 
the focus of the study was the use of Quicktome Software Suite to 
support the identification of areas of eloquent noneloquence, or cortex 
injured or transgressed that causes unexpected deficits. Therefore, we 
remain interested in evidence that incorporating Quicktome Software 
Suite's analytics into surgical strategies and navigational tools 
during craniotomy surgery is associated with improved post-surgical 
outcomes.

---------------------------------------------------------------------------

    With respect to the applicant's claim that damaging brain networks 
during surgery leads to neurologic complications, which are a leading 
contributor to increased length of stay (LOS), ICU admission, and 
readmissions, the applicant asserted that Quicktome Software Suite 
enables surgeons to visualize these brain networks and change their 
surgical approach as needed to avoid damaging these networks. We note 
that the applicant submitted two documents in support of this claim, 
both of which are background documents rather than studies that 
evaluate clinical outcomes associated with the use of Quicktome 
Software Suite. In particular, the Elsamadicy et al. (2018) \96\ study 
showed that altered mental status and sensory or motor deficits were 
the primary complications of craniotomies. The Philips et al. (2023) 
\97\ study demonstrated that post-operative neurological deficits, 
caused by damage to brain networks or a patient's connectome were 
responsible for extended length of stay. Although these studies 
supported the applicant's claim that damage to brain networks resulted 
in neurological complications, increasing LOS and inpatient service 
use, we note that the evidence provided for this claim does not assess 
the use of Quicktome Software Suite to improve these clinical outcomes, 
nor does the evidence appear to demonstrate that use of the technology 
substantially improves these clinical outcomes relative to existing 
technologies, such as StealthVizTM or Brainlab's Elements 
and iPlan products. We would be interested in evidence demonstrating 
that

[[Page 36087]]

utilization of the Quicktome Software Suite improves clinical outcomes 
related to LOS, ICU admissions, and readmissions relative to existing 
technologies.

---------------------------------------------------------------------------

    With respect to the applicant's claim that damaging brain networks 
during surgery has adverse effects for patients, including decreased 
quality of life and loss of function, the applicant asserted that 
Quicktome Software Suite enables surgeons to visualize brain networks 
and change their surgical approach as needed to avoid damaging these 
networks. The applicant further asserted that while other techniques 
have enabled the visualization of tractography or of parts of eloquent 
networks, this is not an adequate substitute for the ability to review 
the entirety of a patient's connectome (networks such as motor, 
language, and vision). Per the applicant, Quicktome Software Suite is 
the first of its kind to show the location and function of these 
networks and that damage to these networks is associated with poor 
outcomes. The applicant cited Vysotski et al. (2019),\98\ who 
demonstrated that brain tumor patients who underwent a preoperative 
fMRI experienced significantly lower risks for mortality than those who 
did not. The applicant also cited Dadario and Sughrue (2022),\99\ who 
discussed the clinical importance of preserving non-traditional brain 
networks for neurosurgical patients. Similar to our previous concern, 
we note that the evidence provided for this claim does not assess the 
use of Quicktome Software Suite to improve quality of life and loss of 
function, nor does the evidence appear to demonstrate that use of the 
technology substantially improves these clinical outcomes relative to 
existing technologies. Therefore, we continue to question whether there 
is evidence to assess the effectiveness of Quicktome Software Suite to 
reduce damage to brain networks during surgery.

k. TALVEYTM (talquetamab-tgvs)
    Johnson & Johnson Health Care Systems, Inc. submitted an 
application for new technology add-on payments for TALVEYTM 
for FY 2025. According to the applicant, TALVEYTM is the 
first and only approved G protein-coupled receptor, class C, group 5, 
member D (GPRC5D) targeting therapy, a bispecific antibody (bsAb) 
approved for the treatment of adults with Relapsed or Refractory 
Multiple Myeloma (RRMM) who have received at least four prior lines of 
therapy (also referred to herein as 4L+RRMM), including a proteasome 
inhibitor (PI), an immunomodulatory agent (IMiD), and an anti-cluster 
of differentiation (CD)38 monoclonal antibody (mAb). GPRC5D is an 
orphan receptor expressed at a significantly higher level on malignant 
Multiple Myeloma (MM) cells than on normal plasma cells.
    Please refer to the online application posting for 
TALVEYTM available at https://mearis.cms.gov/public/publications/ntap/NTP2310163HW2V, for additional detail describing the 
technology and the disease treated by the technology.
    With respect to the newness criterion, according to the applicant, 
TALVEYTM was granted a Biologic License from FDA on August 
9, 2023 for the treatment of adult patients with 4L+RRMM who have 
received at least four prior lines of therapy, including a PI, an ImiD, 
and an anti-CD38 mAb. According to the applicant, TALVEYTM 
was commercially available immediately after FDA approval. Per the 
applicant, patients may be dosed on a weekly or bi-weekly dosing 
schedule. The applicant noted that patients on a weekly dosing schedule 
receive three weight-based doses--a 0.01 mg/kg loading dose, a 0.06 mg/
kg loading dose, and the first 0.40 mg/kg treatment dose--during the 
hospital stay; patients on a bi-weekly dosing schedule receive an 
additional 0.80 mg/kg treatment dose during the hospital stay.
    The applicant submitted a request for approval for a unique ICD-10-
PCS procedure code for TALVEYTM and was granted approval for 
the following procedure code effective April 1, 2024: XW01329 
(Introduction of talquetamab antineoplastic into subcutaneous tissue, 
percutaneous approach, new technology group 9). The applicant stated 
that ICD-10-CM codes C90.00 (Multiple myeloma not having achieved 
remission) and C90.02 (Multiple myeloma in relapse) may be used to 
currently identify the indication for TALVEYTM.
    As previously discussed, if a technology meets all three of the 
substantial similarity criteria under the newness criterion, it would 
be considered substantially similar to an existing technology and would 
not be considered ``new'' for the purpose of new technology add-on 
payments.
    With respect to the substantial similarity criteria, the applicant 
asserted that TALVEYTM is not substantially similar to other 
currently available technologies because it has a unique mechanism of 
action as a CD3 T-cell engaging bsAb targeting GPRC5D, and therefore, 
the technology meets the newness criterion. The following table 
summarizes the applicant's assertions regarding the substantial 
similarity criteria. Please see the online application posting for 
TALVEYTM for the applicant's complete statements in support 
of its assertion that TALVEYTM is not substantially similar 
to other currently available technologies.
BILLING CODE 4120-01-P

BILLING CODE 4120-01-C
    With regard to the newness criterion, we note that 
TALVEYTM may have a similar mechanism of action to that of 
TECVAYLI[supreg], for which we approved an application for new 
technology add-on payments for FY 2024 for the treatment of adult 
patients with RRMM after four or more prior lines of therapy, including 
a PI, an IMiD, and an anti-CD38 mAb (88 FR 58891). We also note that 
TALVEYTM may have a similar mechanism of action to that of 
ELREXFIOTM, another applicant for FY 2025 new technology 
add-on payments. As previously discussed, ELREXFIOTM was 
approved on August 14, 2023 for the treatment of adult patients with 
RRMM who have received at least four prior lines of therapy, including 
a PI, an IMiD, and an anti-CD38 mAb.
    Per the applicant, TALVEYTM has a different mechanism of 
action from TECVAYLI[supreg] or ELREXFIOTM because it binds 
to different receptors. The applicant noted that TALVEYTM is 
the only medicine that targets GPRC5D on myeloma cells. As we 
previously noted, TECVAYLI[supreg]'s mechanism of action is described 
as a bsAb, with binding domains that simultaneously bind the BCMA 
target on tumor cells and the CD3 T-cell receptor (88 FR 58886). As 
previously discussed, the mechanism of action for ELREXFIOTM 
is as a bsAb that uses binding domains that simultaneously bind the 
BCMA target on tumor cells and the CD3 T-cell receptor. However, while 
the applicant asserts that TALVEYTM has a unique mechanism 
of action as compared to TECVAYLI[supreg] and ELREXFIOTM by 
binding to different receptors, we question how binding to a different 
protein (GPRC5D) on the tumor cell would result in a different 
mechanism of action compared to BCMA targeting bispecific antibodies. 
Furthermore, we note that the applicant claimed that the target of 
TALVEYTM, GPRC5D, has a unique tissue expression profile, 
which results in an adverse event profile distinct from those of the 
currently approved bispecific antibodies in RRMM targeting BCMA. 
However, as this relates to the risk of adverse event from 
TALVEYTM administration but is not critical to the way the 
drug treats the underlying disease, we question whether this would 
therefore relate to an assessment of substantial clinical

[[Page 36089]]

improvement rather than of substantial similarity. We would welcome 
additional information on how molecular differences, such as the 
regulation of expression of GPRC5D and BCMA on MM cells during 
treatment, should be considered in determining whether a technology 
utilizes a different mechanism of action to achieve a therapeutic 
outcome.
    Accordingly, as it appears that TALVEYTM and 
TECVAYLI[supreg] may use the same or similar mechanism of action to 
achieve a therapeutic outcome, would be assigned to the same MS-DRG, 
and treat the same or similar patient population and disease, we 
believe that these technologies may be substantially similar to each 
other. We note that if we determine that this technology is 
substantially similar to TECVAYLI[supreg], we believe the newness 
period would begin on November 9, 2022, the date TECVAYLITM 
became commercially available (88 FR 58887).
    Furthermore, as noted, we believe another applicant for FY 2025 new 
technology add-on payments, ELREXFIOTM, may also be 
substantially similar to TALVEYTM. Per the application for 
ELREXFIOTM, ELREXFIOTM is a bispecific antibody 
approved for the treatment of adults with RRMM who have received at 
least four prior lines of therapy, including a PI, an IMiD, and an 
anti-CD38 mAb. We believe ELREXFIOTM may be substantially 
similar to TALVEYTM because it is also a bispecific antibody 
that treats RRMM in patients who have previously received a PI, IMiD, 
and an anti-CD38 mAb. Additionally, we note that similar to 
TALVEYTM, the prescribing information for 
ELREXFIOTM includes the population with prior exposure to 
BCMA T-cell redirection therapy. Accordingly, as it appears that 
TALVEYTM and ELREXFIOTM would use the same or 
similar mechanism of action to achieve a therapeutic outcome, would be 
assigned to the same MS-DRG, and would treat the same or similar 
patient population and disease, we believe that these technologies may 
also be substantially similar to each other such that they should be 
considered as a single application for purposes of new technology add-
on payments. We note that if TALVEYTM is determined to only 
be substantially similar to ELREXFIOTM, and not 
TECVAYLI[supreg], we believe the newness period for TALVEYTM 
would begin on August 9, 2023, the date TALVEYTM received 
FDA approval.
    We are interested in receiving information on how these 
technologies may differ from each other with respect to the substantial 
similarity and newness criteria, to inform our analysis of whether 
TALVEYTM is substantially similar to ELREXFIOTM 
and/or TECVAYLI[supreg].
    We are inviting public comments on whether TALVEYTM is 
substantially similar to existing technologies and whether 
TALVEYTM meets the newness criterion.
    With respect to the cost criterion, to identify potential cases 
representing patients who may be eligible for TALVEYTM, the 
applicant searched the FY 2022 MedPAR for cases reporting one of the 
following ICD-10-CM codes in the first five diagnosis positions on the 
claim: C90.00 (Multiple myeloma not having achieved remission), C90.01 
(Multiple myeloma in remission), and C90.02 (Multiple myeloma in 
relapse). Using the inclusion/exclusion criteria described in the 
following table, the applicant identified 4,468 claims mapping to five 
MS-DRGs with 82 percent of identified cases mapping to MS-DRGs 840 and 
841 (Lymphoma and Non-acute Leukemia with MCC, with CC, respectively). 
The applicant followed the order of operations described in the 
following table and calculated a final inflated average case-weighted 
standardized charge per case of $210,677, which exceeded the average 
case-weighted threshold amount of $77,360. Because the final inflated 
average case-weighted standardized charge per case exceeded the average 
case-weighted threshold amount, the applicant asserted that 
TALVEYTM meets the cost criterion.

    We are inviting public comments on whether TALVEYTM 
meets the cost criterion.
    With regard to the substantial clinical improvement criterion, the 
applicant asserted that TALVEYTM represents a substantial 
clinical improvement over existing technologies because 
TALVEYTM meets two of three criteria for substantial 
clinical improvement due to its off-the-shelf availability without the 
need for complex manufacturing. Additionally, according to the 
applicant, TALVEY\TM\ demonstrates clinically meaningful outcomes in 
heavily pre-treated patients who are exposed or naive to prior T-cell 
redirection therapy and provides a therapeutic option with a lower 
severe infection rate. The applicant provided four studies to support 
these claims. We also note that four other articles submitted as 
supporting evidence should more appropriately be characterized as 
background articles because they do not directly assess the use of 
TALVEYTM. Instead, those four articles focus on existing 
treatment options (ELREXFIOTM or TECVAYLI[supreg]) or the 
high mortality rate of MM patients who died while waiting for CAR-T 
cell therapies.\101\

    \101\ Background articles are not included in the following 
table but can be accessed via the online posting for the technology.

    The following table summarizes the applicant's assertions regarding 
the substantial clinical improvement criterion. Please see the online

regarding the substantial clinical improvement criterion and the 
supporting evidence provided.

BILLING CODE 4120-01-C
    After review of the information provided by the applicant, we have 
the following concerns regarding whether TALVEYTM meets the 
substantial clinical improvement criterion. With respect to the 
applicant's claim that TALVEYTM offers an efficacious 
treatment option for patients who are unable to receive CAR T-cell 
therapy, we note that TECVAYLI[supreg] and ELREXFIOTM are 
recently FDA-approved alternatives to CAR T-cell therapy with the same 
indication as treatments for RRMM for patients ineligible or 
unresponsive to four prior lines of therapy, including a PI, an IMiD, 
and an anti-CD38 mAb. In addition, although the applicant claimed that 
TALVEYTM is more accessible than CAR T-cell therapies 
because it is readily available and can be delivered at any acute care 
hospitals, we would be interested in evidence comparing the effects of 
TALVEYTM and CAR T-cell therapies on mortality and other 
clinical outcomes, as we did not receive results from clinical trials 
comparing the efficacy of TALVEYTM with CAR T-cell 
therapies.
    With respect to the applicant's claim that TALVEYTM has 
a low incidence of serious and higher-grade infections and preserves B-
cell function, we note that the clinical data from the Hammons et al. 
(2023) \102\ study did not appear to support this claim. Specifically, 
the difference in the proportion of grade 3+ infections among patients 
treated with BCMA bsAb (58 percent), GPRC5D bsAb combination therapy 
with daratumumab and/or pomalidomide (33 percent), and GPRC5D bsAb 
monotherapy (50 percent) was not statistically significant (p = 0.06). 
While the total infection rate per 100 days was lower for the GPRC5D 
monotherapy group, the difference was not statistically significant 
(BCMA: 0.57 percent, GPRC5D combination: 0.62 percent, GPRC5D 
monotherapy: 0.13 percent; p = 0.06). Moreover, the differences among 
the three groups in bacterial, viral, and fungal infection rates per 
100 days did not reach statistical significance (p = 0.07, 0.4, and 
0.14 respectively). In addition, the difference among the three groups 
regarding the need for hospitalization was not statistically 
significant (p = 0.07). Similarly, we note that according to the 
Rodriguez-Otero et al. (2023) \103\ poster presentation, of the 339 
patients treated with TALVEYTM, 64 percent (n = 217) 
experienced infections, of which 29 percent (n = 63) experienced grade 
3-4 infections. The applicant highlighted a conclusion in the 
Rodriguez-Otero poster that infection

[[Page 36092]]

rates, particularly rates of higher grade and fatal infections, 
occurred less frequently with TALVEYTM compared with those 
observed in BCMA-targeted T-cell based therapies. We note that because 
clinical trials are conducted under widely varying conditions, we 
question whether adverse reaction rates observed in the clinical trials 
of one drug can be directly compared to rates in the clinical trials of 
another drug without an effort to adjust for such conditions.

---------------------------------------------------------------------------

    With respect to the applicant's claim that TALVEYTM 
offers clinically meaningful outcomes in heavily pre-treated patients 
na[iuml]ve to prior bsAb and CAR T-cell therapy, we note that the 
applicant compared the results from MonumenTAL-1, the ongoing 
TALVEYTM clinical study, with clinical study results of 
TECVAYLI[supreg] and ELREXFIOTM.104 105 The 
applicant noted that the overall response rates (ORRs) for 
TALVEYTM's 0.4 mg/kg weekly and 0.8 mg/kg biweekly cohorts 
of 74.1 percent and 71.7 percent respectively seem higher than the 
response rates reported for TECVAYLI[supreg] (63 percent) and 
ELREXFIOTM (61 percent). The applicant also noted the 
duration of response (DOR), progression free survival (PFS), and 
overall survival (OS) for TALVEYTM were comparable to that 
of the BCMA bispecific antibodies. However, we note that this was based 
on a comparison of three separate clinical trials, which can involve 
numerous confounding variables, and the applicant did not provide 
supporting data related to clinical trial design or statistical 
analysis to explain why the potential effects of confounding variables 
should not be a concern for purposes of this comparison. Therefore, we 
are interested in additional evidence demonstrating that 
TALVEYTM significantly improves clinical outcomes compared 
to BCMA bispecific antibodies in heavily pre-treated patients 
na[iuml]ve to prior bispecific antibody and CAR T-cell therapy that 
adjusts for the effects of confounding factors.

past results from MonumenTAL-1 that included a cohort of 51 patients 
with prior T-cell redirection therapies (TCR) including BCMA-directed 
CAR-T therapies and/or bispecific antibodies, citing an ORR of 64.7 
percent in these heavily pre-treated patients.\106\ The applicant also 
provided updated results that included an additional 19 patients with 
prior TCR that demonstrated similar efficacy, noting slightly higher 
ORRs and improved PFS and DOR rates in patients with prior BCMA CAR T-
cell versus prior bispecific antibody therapies. We welcome additional 
information demonstrating the efficacy of TALVEYTM in 
patients previously treated with BCMA-directed TCRs.

l. Odronextamab, First Indication: Relapsed or Refractory Diffuse Large 
B-Cell Lymphoma (R/R DLBCL)
    Regeneron Pharmaceuticals, Inc. submitted an application for new 
technology add-on payments for odronextamab for use in relapsed or 
refractory diffuse large B-cell lymphoma (R/R DLBCL) for FY 2025. 
According to the applicant, odronextamab is the first and only novel, 
fully-human Cluster of Differentiation (CD) 20 x CD 3 bispecific 
antibody (bsAb) with an immunoglobulin G4 (IgG4)-based structure in B-
Cell non-Hodgkin lymphoma (B-NHL) created using Regeneron's proprietary 
Veloci-Bi[supreg] technology that is designed to simultaneously bind to 
two types of antigens, CD20 found on both healthy and cancerous B 
cells, and CD3 found on T-cells. Per the applicant, simultaneous 
engagement of both arms of odronextamab results in the activation of 
immune system T-cells, causing it to generate cytotoxic T-cells that 
can destroy the targeted cells, including cancerous B-cells. We note 
that Regeneron Pharmaceuticals, Inc. also submitted an application for 
new technology add-on payments for odronextamab for use in relapsed or 
refractory follicular lymphoma (R/R FL) for FY 2025, as discussed 
separately later in this section.
    Please refer to the online application posting for odronextamab, 
available at https://mearis.cms.gov/public/publications/ntap/NTP231017LHBUG, for additional detail describing the technology and the 
disease treated by the technology.
    With respect to the newness criterion, the applicant stated that 
its marketing authorization request for odronextamab has been filed by 
FDA and that it anticipates a Biologic License Application (BLA) 
decision from FDA for adults with R/R DLBCL after at least two prior 
systemic therapies, including patients with or without prior CAR T-cell 
therapy, before May 1, 2024. According to the applicant, odronextamab 
will be commercially available immediately after FDA approval. 
According to the applicant, it anticipates that inpatient usage of 
odronextamab might occur due to a physician's order or as a result of 
an adverse event, such as cytokine release syndrome (CRS) Grade 2 or 
higher, that results in an inpatient admission. The applicant noted 
that in the pivotal Phase 2 clinical trial (ELM-2), when CRS Grade 2 or 
3 events developed among DLBCL patients (there were no CRS Grade 4 or 
higher reported on the recommended dosing regimen), 31 percent of the 
time it occurred after the initial dose (0.7 mg), 46 percent after the 
first intermediate dose (4 mg), 15 percent after the second 
intermediate dose (20 mg), 0 percent after the first full dose (160 
mg), and 8 percent after the second full dose & beyond (160 mg). Using 
this information, the applicant developed a weighted average inpatient 
dose of 17.4 mg.
    According to the applicant, there are currently no ICD-10-PCS 
procedure codes to distinctly identify odronextamab. We note that the 
applicant submitted a request for approval for a unique ICD-10-PCS 
procedure code for odronextamab beginning in FY 2025. The applicant 
provided a list of diagnosis codes that may be used to currently 
identify this indication for odronextamab under the ICD-10-CM coding 
system. Please refer to the online application posting for the complete 
list of ICD-10-CM codes provided by the applicant. We believe the 
relevant ICD-10-CM codes to identify the indication of R/R DLBCL would 
be the codes included in category C83 (Non-follicular lymphoma) under 
the ICD-10-CM classification in subcategory: C83.3- (Diffuse large B-
cell

[[Page 36093]]

lymphoma). We are inviting public comments on the use of these ICD-10-
CM diagnosis codes to identify the indication of R/R DLBCL for purposes 
of the new technology add-on payment, if approved.
    As previously discussed, if a technology meets all three of the 
substantial similarity criteria under the newness criterion, it would 
be considered substantially similar to an existing technology and would 
not be considered ``new'' for the purpose of new technology add-on 
payments.
    With respect to the substantial similarity criteria, the applicant 
asserted that odronextamab is not substantially similar to other 
currently available technologies. According to the applicant, the 
mechanism of action for odronextamab presents noteworthy distinctions, 
such as reduced potential for immunogenicity and anti-drug antibodies 
through its novel fully human design and reduced ability to elicit an 
immune response through the blocking effect of the IgG4-based 
structure. The applicant also asserted that odronextamab is the only 
bispecific antibody (bsAb) with a dedicated prospective cohort that 
shows efficacy in patients with R/R DLBCL with prior CAR T-cell therapy 
while also showing comparable efficacy in patients without prior CAR T-
cell therapy, and that therefore, the technology meets the newness 
criterion. The following table summarizes the applicant's assertions 
regarding the substantial similarity criteria. Please see the online 
application posting for odronextamab for the applicant's complete 
statements in support of its assertions that odronextamab is not 
substantially similar to other currently available technologies.

[[Page 36094]]


    We note that according to the applicant, odronextamab may have a 
similar mechanism of action to that of EPKINLYTM 
(epcoritamab) and COLUMVITM (glofitamab), for which we 
approved an application for new technology add-on payments for FY 2024 
(88 FR 58835) for the treatment of adult patients with R/R DLBCL after 
two or more prior lines of systemic therapy. Specifically, a similar 
IgG bsAb engaging CD3 x CD20 mechanism is utilized in the treatment of 
the same population of R/R DLBCL adult patients with two or more prior 
therapies. Although the applicant asserts that odronextamab is the 
first and only fully human, IgG4-based bsAb in B-NHL, which may help 
reduce potential for immunogenicity and anti-drug antibodies, we 
believe that this would relate to the risk of adverse event from 
odronextamab administration but is not critical to the way the drug 
treats the underlying disease, and therefore would relate to an 
assessment of substantial clinical improvement, rather than of 
substantial similarity.
    The applicant asserts that it treats a new patient population 
because it is indicated for a sub-population of patients within R/R 
DLBCL: adult patients with two or more prior therapies after transplant 
or CAR T-cell therapy. However, as noted by the applicant, both 
EPKINLYTM and COLUMVITM may also be used for 
patients with R/R DLBCL with disease progression after transplant or 
CAR T-cell therapy, also after two or more lines of systemic therapies. 
Therefore, we believe that odronextamab may treat the same or similar 
disease in the same or similar patient population as 
EPKINLYTM and COLUMVITM. Accordingly, as it 
appears that odronextamab, and EPKINLYTM and 
COLUMVITM may use the same or similar mechanism of action to 
achieve a therapeutic outcome, would be assigned to the same MS-DRG, 
and treat the same or similar patient population and disease, we 
believe that these technologies may be substantially similar to each 
other. We note that if we determine that this technology is 
substantially similar to EPKINLYTM and COLUMVITM, 
we believe the newness period for this technology would begin on May 
19, 2023, the date on which EPKINLYTM received FDA approval, 
which is the earliest market availability date submitted for 
EPKINLYTM and COLUMVITM. We are interested in 
information on how these technologies may differ from each other with 
respect to the substantial similarity criteria and newness criterion.
    We are inviting public comments on whether odronextamab meets the 
newness criterion, including whether odronextamab is substantially 
similar to EPKINLYTM and COLUMVITM or other 
existing technologies.
    With respect to the cost criterion, the applicant provided multiple 
analyses to demonstrate that it meets the cost criterion. For each 
analysis, the applicant searched the FY 2022 MedPAR using a combination 
of ICD-10-CM and/or PCS codes to identify potential cases representing 
patients who may be eligible for odronextamab. The applicant explained 
that it used different codes to demonstrate different cohorts that may 
be eligible for the technology. Each analysis followed the order of 
operations described in the tables later in this section.
    For the first analysis, the applicant used a list of ICD-10-CM 
diagnosis codes to identify cases with primary diagnosis of DLBCL. The 
applicant excluded cases with a corresponding ICD-10-CM or ICD-10-PCS 
code indicating active treatment. Per the applicant, active treatment 
was defined as allogeneic stem cell transplant, bone marrow transplant, 
transplant complications, chemotherapy administration, immunotherapy, 
or radiation. Please see the online posting for odronextamab for the 
complete list of codes provided by the applicant. The applicant used 
the inclusion/exclusion criteria described in the following table. 
Under this analysis, the applicant identified 3,066 claims mapping to 
10 MS-DRGs, including MS-DRG 840 (Lymphoma and Non-Acute Leukemia with 
MCC) representing 34.9 percent of the identified cases. The applicant 
calculated a final inflated average case-weighted standardized charge 
per case of $141,787, which exceeded the average case-weighted 
threshold amount of $106,031.
    For the second analysis, the applicant identified cases using a 
list of ICD-10-CM diagnosis codes: T80.89XA (Other complications 
following infusion, transfusion, and therapeutic injection) or D89.832-
D89.839 (Cytokine release syndrome (CRS) Grades 2-5 or unspecified) in 
any position. The applicant used the inclusion/exclusion criteria 
described in the following table. Under this analysis, the applicant 
identified 80 claims mapping to two MS-DRGs: 018 (Chimeric Antigen 
Receptor (CAR) T-Cell and Other Immunotherapies) and 811 (Red Blood 
Cell Disorders with MCC). The applicant calculated a final inflated 
average case-weighted standardized charge per case of $1,095,920, which 
exceeded the average case-weighted threshold amount of $936,675.
    Because the final inflated average case-weighted standardized 
charge per case exceeded the average case-weighted threshold amount in 
all scenarios, the applicant maintained that odronextamab meets the 
cost criterion.

    We are inviting public comments on whether odronextamab meets the 
cost criterion.
    With regard to the substantial clinical improvement criterion, the 
applicant asserted that odronextamab represents a substantial clinical 
improvement over existing technologies because odronextamab offers a 
new treatment for patients who are ineligible for CAR T-cell therapy 
and represents a substantial clinical improvement over existing 
technologies in patients with R/R DLBCL, including those with or 
without prior CAR T-cell therapy. According to the applicant, 
odronextamab will expand access to heavily pretreated, highly 
refractory patients and will offer patients with R/R DLBCL a new 
monotherapy that demonstrates substantial clinical benefits, including 
a generally manageable safety profile and favorable Health Related 
Quality of Life (HRQoL). The applicant also asserted that odronextamab 
significantly improves clinical outcomes relative to services or 
technologies previously available (such as EPKINLY\TM\ and 
COLUMVI\TM\). The applicant provided three studies to support these 
claims, as well as nine background articles about other therapies.\107\ 
The following table summarizes the applicant's assertions regarding the 
substantial clinical improvement criterion. Please see the online 
posting for odronextamab for the applicant's complete statements 
regarding the substantial clinical improvement criterion and the 
supporting evidence provided.

BILLING CODE 4120-01-C
    After review of the information provided by the applicant, we have 
the following concerns regarding whether odronextamab meets the 
substantial clinical improvement criterion. We note that with respect 
to the claim that odronextamab will increase treatment options for 
patients with relapsed or refractory diffuse large B-cell lymphoma (R/R 
DLBCL) who have a high risk of cytokine release syndrome (CRS), the 
applicant submitted the oral presentation slides of the results from a 
pre-specified analysis by Kim et al. (2022),\108\ presenting the 
interim results for the Phase II trial for odronextamab, ELM-2. In this 
trial, 140 patients (median age: 66 years) with R/R DLBCL after 2 or 
more lines of therapy, Eastern Cooperative Oncology Group (ECOG) 0 or 
1, were assigned to receive either a

[[Page 36098]]

1/20 mg step-up regimen (n = 67) or 0.7/4/20 mg step-up regimen (n = 
73) after the study initiated with a first cycle of step-up regimen of 
1/20 mg. The regimen was modified to 0.7/4/20 mg during Cycle 1 to 
further mitigate the risk of CRS. The rates of CRS grades 2 and 3 for 
patients grouped to the 1/20 regimen were 17.9 percent and 7.5 percent 
respectively, while rates of CRS grades 2 and 3 for patients grouped to 
the 0.7/4/20 regimen were 13.7 percent and 1.4 percent. We note that 
although the incidence of grade 3 CRS was lower in the 0.7/4/20 regimen 
arm, the applicant indirectly compared these incidence rates with the 
rates of trials as found in the prescribing information for other 
existing technologies, including EPKINLY\TM\ and COLUMVI\TM\, and it is 
unclear if these differences are statistically significant. We also 
question whether there are differences between these clinical trials, 
such as patient characteristics or other confounding variables, which 
would limit such comparability between CRS incidence rates. We are 
concerned as to whether the differences identified by the applicant 
translate to clinically meaningful improvements for patients treated 
with odronextamab as compared to rates for existing treatments.

12, 2022.
---------------------------------------------------------------------------

    With respect to the claim that odronextamab monotherapy is an 
effective treatment option for patients with R/R DLBCL including those 
with or without prior CAR T-cell therapy, the applicant submitted the 
oral presentation slides of the results from a pre-specified analysis 
by Kim et al. (2022),\109\ previously described. The oral presentation 
slides refer to the Phase 1 trial for odronextamab (ELM-1) and indicate 
consistency of results across trials. The applicant noted that patients 
with prior CAR-T therapy demonstrated an objective response rate (ORR) 
of 48.4 percent (95 percent CI: 30.2, 66.9), and a Complete Response 
(CR) rate of 32.3 percent (n = 44 patients). The applicant cited other 
information about CD20xCD3 bsAbs in patients with R/R DLBCL including 
the United States Prescribing Information (USPI) for EPKINLY\TM\ and 
COLUMVI\TM\ for which 29 percent and 30 percent of patients 
respectively were refractory to CAR T-cell therapy. We note that the 
provided evidence did not compare the efficacy of odronextamab to 
EPKINLY\TM\ or COLUMVI\TM\. Similar to our earlier concern, we question 
whether there are confounding factors between studies that would limit 
indirect comparisons of ORR and CR. We would be interested in 
additional evidence to assess the use of odronextamab in improving 
these clinical outcomes relative to existing treatments.

---------------------------------------------------------------------------

    With respect to the claim that the odronextamab clinical program 
enrolled heavily pre-treated and highly refractory patients with high-
grade non-Hodgkins Lymphoma (NHL) and sicker patients based on a worse 
ECOG performance status, the applicant submitted the oral slides of the 
results from a pre-specified analysis by Kim et al. (2022),\110\ 
previously described, and the peer-reviewed publication of the 
EPKINLY\TM\ dose expansion cohort of the phase I/II clinical trial. 
ECOG performance status is based on a five-point scale, with higher 
numbers indicating greater disability. Both trials included patients 
with ECOG performance status of 0 or 1 and the EPKINLY\TM\ trial also 
included ECOG performance status scores of 2; the odronextamab trial (n 
= 140) had rates of 32.1 percent and 67.9 percent for ECOG 0 and 1 
respectively, whereas the EPKINLY\TM\ trial has ECOG performance status 
scores of 47.1 percent, 49.7 percent, and 3.2 percent for ECOG 0, 1, 
and 2 respectively. However, we note that these incidence rates of 
patient characteristics are indirectly compared across unrelated 
clinical trials and patient outcomes are not stratified in either trial 
based on these characteristics. For example, we note that the 
classification of ``worse ECOG status'' in the odronextamab trial had a 
higher incidence rate of patients with ECOG 1 performance status, but 
this trial did not include patients with ECOG 2 performance status, as 
did the EPKINLY\TM\ trial.

---------------------------------------------------------------------------

    With regards to the applicant's assertions that odronextamab 
significantly improves clinical outcomes relative to existing 
technologies because it is the first CD20xCD3 bsAb to report long-term 
patient outcomes at longest follow-up of 4.5 years, and that treatment 
until disease progression may have benefits on HRQoL for heavily 
pretreated patients with R/R DLBCL and potentially addresses unmet 
needs in a challenging treatment setting, we are concerned that the 
evidence presented does not compare these outcomes to existing 
technologies, such as EPKINLY\TM\ or COLUMVI\TM\. For example, although 
the applicant stated that odronextamab is the first to report on long-
term patient outcomes with the longest follow-up, there does not appear 
to be evidence demonstrating comparisons of long-term patient outcomes 
of odronextamab to existing technologies to support its claim that the 
technology improves clinical outcomes. In addition, there does not 
appear to be evidence of a direct HRQoL comparison to existing 
technologies to assess improvements to HRQoL for heavily pretreated 
patients with R/R DLBCL. Therefore, we welcome additional evidence 
demonstrating comparisons of odronextamab to existing technologies to 
support the applicant's claims.
    We are inviting public comments on whether odronextamab meets the 
substantial clinical improvement criterion.
    We did not receive any written comments in response to the New 
Technology Town Hall meeting notice published in the Federal Register 
regarding the substantial clinical improvement criterion for 
odronextamab.
m. Odronextamab, Second Indication: Relapsed or Refractory Follicular 
Lymphoma (R/R FL)
    Regeneron Pharmaceuticals, Inc. submitted an application for new 
technology add-on payments for odronextamab for use in relapsed or 
refractory follicular lymphoma (R/R FL) for FY 2025. According to the 
applicant odronextamab is the first and only novel, fully-human Cluster 
of Differentiation (CD) 20 x CD 3 bispecific antibody (bsAb) with an 
immunoglobulin G4 (IgG4)-based structure in B-Cell non-Hodgkin lymphoma 
(B-NHL) created using Regeneron's proprietary Veloci-Bi[supreg] 
technology that is designed to simultaneously bind to two types of 
antigens, CD20, found on both healthy and cancerous B cells, and CD3, 
found on T-cells. Per the applicant, simultaneous engagement of both 
arms of odronextamab results in the activation of immune system T-
cells, causing it to generate cytotoxic T-cells that can destroy the 
targeted cells, including cancerous B cells. As previously discussed 
earlier in this section, Regeneron Pharmaceuticals, Inc. also submitted 
an application for new technology add-on payments for odronextamab for 
use in relapsed or refractory diffuse large B-cell lymphoma (R/R DLBCL) 
for FY 2025.

available at https://mearis.cms.gov/public/

publications/ntap/NTP231017YATW9, for additional detail describing the 
technology and B-NHL R/R FL.
    With respect to the newness criterion, the applicant stated that 
its marketing authorization request for odronextamab has been filed by 
FDA and that it anticipates a Biologic License Application (BLA) 
decision from FDA for adults with R/R FL after at least two prior 
systemic therapies, before May 1, 2024. According to the applicant, 
odronextamab will be commercially available immediately after FDA 
approval. According to the applicant, it anticipates that inpatient 
usage of odronextamab might occur due to a physician's order or as a 
result of an adverse event, such as cytokine release syndrome (CRS) 
Grade 2 or higher, that results in an inpatient admission. The 
applicant noted that in the pivotal Phase 2 clinical trial (ELM-2), 
when CRS Grade 2 or 3 events developed among FL patients (there were no 
CRS Grade 4 or higher reported on the recommended dosing regimen), 20 
percent of the time they occurred after the initial dose (0.7 mg), 50 
percent of the time after the first intermediate dose (4 mg), 20 
percent of the time after the second intermediate dose (20 mg), 0 
percent of the time after the first full dose (80 mg), and 10 percent 
of the time after the second full dose and beyond (80 mg). Using this 
information, the applicant developed a weighted average inpatient dose 
of 14.1 mg.
    According to the applicant, there are currently no ICD-10-PCS 
procedure codes to distinctly identify odronextamab. We note that the 
applicant submitted a request for approval for a unique ICD-10-PCS 
procedure code for odronextamab beginning in FY 2025. The applicant 
provided a list of diagnosis codes that may be used to currently 
identify this indication for odronextamab under the ICD-10-CM coding 
system. Please refer to the online application posting for the complete 
list of ICD-10-CM codes provided by the applicant. We believe the 
relevant ICD-10-CM codes to identify the indication of R/R FL would be 
the codes included in category C82 (Follicular lymphoma) under the ICD-
10-CM classification in subcategories: C82.0--(Follicular lymphoma 
grade I), C82.1--(Follicular lymphoma grade II), C82.2--(Follicular 
lymphoma grade III, unspecified), C82.3--(Follicular lymphoma grade 
IIIa), C82.4--(Follicular lymphoma grade IIIb), C82.5--(Diffuse 
follicle center lymphoma), C82.6--(Cutaneous follicle center lymphoma), 
C82.8--(Other types of follicular lymphoma), or C82.9--(Follicular 
lymphoma, unspecified). We are inviting public comments on the use of 
these ICD-10-CM diagnosis codes to identify the indication of R/R FL 
for purposes of the new technology add-on payment, if approved.
    As previously discussed, if a technology meets all three of the 
substantial similarity criteria under the newness criterion, it would 
be considered substantially similar to an existing technology and would 
not be considered ``new'' for the purpose of new technology add-on 
payments.
    With respect to the substantial similarity criteria, the applicant 
asserted that odronextamab is not substantially similar to other 
currently available technologies because its mechanism of action 
presents notable distinctions, such as reduced potential for 
immunogenicity and anti-drug antibodies through its novel, fully human 
design and reduced ability to elicit an immune response through the 
blocking effect of the IgG4-based structure. The applicant further 
asserted that odronextamab also has demonstrated efficacy in patients 
with FL Grade 3b, which were excluded from the GO29781 study of 
mosunetuzumab, and offers consistent efficacy in other high-risk 
subgroups of patients with R/R FL, and that therefore, the technology 
meets the newness criterion. The following table summarizes the 
applicant's assertions regarding the substantial similarity criteria. 
Please see the online application posting for odronextamab for the 
applicant's complete statements in support of its assertion that 
odronextamab is not substantially similar to other currently available 
technologies.

[[Page 36100]]

[GRAPHIC] [TIFF OMITTED] TP02MY24.123

BILLING CODE 4120-01-C
    With regard to the newness criterion, we note that according to the 
applicant odronextamab may have a similar mechanism of action to that 
of LunsumioTM (mosunetuzumab), another IgG bsAb engaging 
CD3xCD20, for which we approved an application for new technology add-
on payments for FY 2024 (88 FR 58844), which treats the same population 
of R/R FL adult patients with two or more prior therapies. Although the 
applicant states that there are key distinctions between the mechanism 
of action of odronextamab and LunsumioTM because 
odronextamab is the first and only fully human, IgG4-based bsAb, which 
provides additional binding sites and reduces its ability to elicit an 
inflammatory immune response, we do not believe that the number of 
binding sites results in a different mechanism of action. We also 
believe that a reduction in inflammatory immune response would relate 
to the risk of an adverse event from odronextamab administration but is 
not critical to the way the drug treats the underlying disease, and 
therefore would relate to an assessment of substantial clinical 
improvement, rather than of substantial similarity.
    The applicant asserted that odronextamab treats a sub-population of 
patients within the R/R FL adult

[[Page 36101]]

patients with two or more prior therapies in its summary, specifically, 
that of R/R FL Grade 3b--a rare subgroup of patients who are generally 
excluded from clinical trials.\111\ However, we note that the FDA-
approved labeling for LunsumioTM does not appear to exclude 
this patient population. As such, it is unclear whether odronextamab 
would treat a patient population different from other CD20 x CD3 IgG 
bsAbs that treat patients with R/R FL, such as LunsumioTM. 
Accordingly, as it appears that odronextamab and LunsumioTM 
may use the same or similar mechanism of action to achieve a 
therapeutic outcome, would be assigned to the same MS-DRG, and treat 
the same or similar patient population and disease, we believe that 
these technologies may be substantially similar to each other. We note 
that if we determine that this technology is substantially similar to 
LunsumioTM, we believe the newness period for this 
technology would begin on December 22, 2022, the date 
LunsumioTM received FDA approval.

---------------------------------------------------------------------------

    We are inviting public comments whether odronextamab meets the 
newness criterion, including whether odronextamab is substantially 
similar to LunsumioTM or other existing technologies.
    With respect to the cost criterion, the applicant provided multiple 
analyses to demonstrate that it meets the cost criterion. For each 
analysis, the applicant searched the FY 2022 MedPAR using a combination 
of ICD-10-CM and/or PCS codes to identify potential cases representing 
patients who may be eligible for odronextamab. The applicant explained 
that it used different codes to demonstrate different cohorts that may 
be eligible for the technology. Each analysis followed the order of 
operations described in the tables later in this section.
    For the first analysis the applicant used a list of ICD-10-CM 
diagnosis codes to identify cases with primary diagnoses of follicular 
lymphoma. The applicant excluded cases with a corresponding ICD-10-CM 
or ICD-10-PCS code indicating active treatment. Per the applicant, 
active treatment was defined as allogeneic stem cell transplant, bone 
marrow transplant, transplant complications, chemotherapy 
administration, immunotherapy, or radiation. Please see the online 
posting for odronextamab for the complete list of codes provided by the 
applicant. The applicant used the inclusion/exclusion criteria 
described in the following table. Under this analysis, the applicant 
identified 482 claims mapping to nine MS-DRGs, including MS-DRG 840 
(Lymphoma and Non-Acute Leukemia with MCC) representing 29.3 percent of 
the identified cases. The applicant followed the order of operations 
described in the following table and calculated a final inflated 
average case-weighted standardized charge per case of $101,177 which 
exceeded the average case-weighted threshold amount of $95,779.
    For the second analysis the applicant identified cases using a list 
of ICD-10-CM diagnosis codes: T80.89XA (Other complications following 
infusion, transfusion, and therapeutic injection) or D89.832-D89.839 
(Cytokine release syndrome (CRS) Grades 2-5 or unspecified) in any 
position. The applicant used the inclusion/exclusion criteria described 
in the table later in this section. Under this analysis, the applicant 
identified 80 claims mapping to two MS-DRGs, including 018 (Chimeric 
Antigen Receptor (CAR) T-Cell and Other Immunotherapies) and 811 (Red 
Blood Cell Disorders with MCC). The applicant calculated a final 
inflated average case-weighted standardized charge per case of 
$1,095,920, which exceeded the average case-weighted threshold amount 
of $963,675.
    Because the final inflated average case-weighted standardized 
charge per case exceeded the average case-weighted threshold amount in 
all scenarios, the applicant asserted that odronextamab meets the cost 
criterion.

    With regard to the substantial clinical improvement criterion, the 
applicant asserted that odronextamab represents a substantial clinical 
improvement over existing technologies because it will expand access to 
heavily pretreated, highly refractory patients for whom existing 
therapies are not adequate. According to the applicant, treatment with 
odronextamab offers patients with R/R FL a new, readily available 
monotherapy that demonstrates multiple substantial clinical benefits, 
including a generally manageable safety profile, and establishes a new 
benchmark for efficacy. The applicant also asserted that odronextamab 
significantly improves clinical outcomes relative to services or 
technologies previously available (such as LunsumioTM). The 
applicant provided three studies to support these claims, as well as 
eight background articles about other therapies for the R/R FL patient 
population.\113\ The following table summarizes the applicant's 
assertions regarding the substantial clinical improvement criterion.

criterion and the supporting evidence provided.

BILLING CODE 4120-01-C
    After review of the information provided by the applicant, we have 
the following concerns regarding whether odronextamab meets the 
substantial clinical improvement criterion. We note that with respect 
to the claim that odronextamab will increase treatment options for 
patients with R/R FL who have a high risk of CRS, the applicant 
submitted the oral presentation slides of the results from a pre-
specified analysis by Kim et al. (2022),\114\ presenting the

[[Page 36105]]

interim results for the Phase II trial for odronextamab on the FL 
cohort, ELM-2. In this Phase II trial, 131 patients (median age: 61 
years) with R/R FL after two or more lines of therapy were grouped to 
receive a 1/20 mg step-up regimen (n = 68) or 0.7/4/20 mg step-up 
regimen (n = 53) after the study initiated with a first cycle of step-
up regimen of 1/20 mg. The regimen was modified to 0.7/4/20 mg during 
Cycle 1 to further mitigate the risk of CRS. The rates of CRS grades 2 
and 3 for the 1/20 regimen are 17.6 percent and 5.9 percent, 
respectively, compared to the CRS grades 2 and 3 for the 0.7/4/20 
regimen of 11.1 percent and 1.6 percent. We note that although the 
incidence of grade 3 CRS was lower in the 0.7/4/20 regimen arm, the 
applicant submitted the United States Prescribing Information (USPI) 
for other therapies (including LunsumioTM and 
tisagenlecleucel) used to treat R/R FL patients to provide the CRS 
rates following treatment with existing therapies. As the applicant 
indirectly compared these incidence rates with those rates of trials as 
found in the prescribing information for other existing technologies, 
it is unclear if these differences are statistically significant. We 
note that because clinical trials are conducted under widely varying 
conditions, we question whether adverse reaction rates observed in the 
clinical trials of one drug can be directly compared to rates in the 
clinical trials of another drug. We question whether such comparisons 
across clinical trial cohorts adequately provide evidence of reduced 
adverse events in patients treated with odronextamab.

the pivotal Phase II study ELM-2. Presented at American Society of 
Hematology (ASH). December 12, 2022.
---------------------------------------------------------------------------

    Similarly, we note that with respect to the claim that odronextamab 
offers patients with heavily pretreated, highly refractory FL a new, 
readily available, monotherapy that establishes a new benchmark for 
efficacy, the applicant submitted the objective response rates (ORR) 
and complete response rates (CR) of its Phase II study, ELM-2 and 
compared them to the ORR and CR rates of the LunsumioTM 
GO29781 study. We note the same concerns as with the previous claim 
about comparing outcomes across studies given the variability in 
clinical trial design.
    With respect to the claim that odronextamab demonstrated efficacy 
in patients with FL Grade 3b disease in the ELM-2 study, although the 
applicant provided additional analysis from the ELM-2 study where 
odronextamab demonstrated efficacy across six patients enrolled in the 
study with FL Grade 3B, we note that it is unclear whether the 
additional analysis that was provided in addition to the ELM-2 study 
represents an ad-hoc analysis, therefore, we are concerned about 
drawing conclusions from this ad-hoc analysis to appropriately 
demonstrate efficacy in the FL Grade 3B subgroup. Furthermore, we are 
concerned that the applicant did not compare the results of the study 
to the efficacy of existing therapies for patients with FL Grade 3B. We 
would be interested in additional evidence comparing outcomes between 
odronextamab and existing therapies such as Breyanzi[supreg], which is 
also approved for patients with FL Grade 3B with relapsed or refractory 
disease after two or more lines of systemic therapy.
    With respect to the claim that patients in the FL cohort of the 
ELM-2 study exhibited more unfavorable select baseline characteristics 
compared to those in the LunsumioTM study, the applicant 
presented the analysis for odronextamab by Kim et al. (2022),\115\ 
described previously, and the LunsumioTM phase 2 study on R/
R patients with FL.\116\ The applicant stated that patients treated 
with odronextamab in the ELM-2 cohort had received prior autologous 
stem cell transplants at a higher rate (30.5 percent) than those 
treated in the LunsumioTM study (21%). The applicant also 
noted additional unfavorable select baseline characteristics for 
patients in the ELM-2 study compared to patients in the 
LunsumioTM study, including: more patients with a worse 
Eastern Cooperative Oncology Group (ECOG) performance status, as 48.1 
percent of patients in ELM-2 had an ECOG performance status of 1, 
compared to 41 percent of patients in the LunsumioTM study; 
more patients with an Ann Arbor stage III-IV (84.7 percent of patients, 
compared to 77 percent of patients in the LunsumioTM study); 
more patients with a FLIPI score of 3-5 (58.8 percent of patients, 
compared to 44 percent of patients in the LunsumioTM study); 
and more older patients, with 38.9 percent of patients >=65 years old 
(median age of 61), compared to a median age of 60 for 
LunsumioTM. We note these are indirect rate comparisons 
across clinical trials without statistical adjustments performed across 
the patient populations and clinical outcomes. We also note that 
differences in patient characteristics across any two clinical trials, 
even with the same selection criteria, are likely to occur. As such, we 
question whether the comparison of baseline characteristics across 
cohorts in independent clinical trials can be taken as indicative of 
differences in clinical outcomes or efficacy between treatments.

6. Proposed FY 2025 Applications for New Technology Add-On Payments 
(Alternative Pathways)
    As discussed previously, beginning with applications for FY 2021, a 
medical device designated under FDA's Breakthrough Devices Program that 
has received marketing authorization as a Breakthrough Device, for the 
indication covered by the Breakthrough Device designation, may qualify 
for the new technology add-on payment under an alternative pathway. 
Additionally, beginning with FY 2021, a medical product that is 
designated by the FDA as a Qualified Infectious Disease Product (QIDP) 
and has received marketing authorization for the indication covered by 
the QIDP designation, and, beginning with FY 2022, a medical product 
that is a new medical product approved under FDA's Limited Population 
Pathway for Antibacterial and Antifungal Drugs (LPAD) and used for the 
indication approved under the LPAD pathway, may also qualify for the 
new technology add-on payment under an alternative pathway. Under an 
alternative pathway, a technology will be considered not substantially 
similar to an existing technology for purposes of the new technology 
add-on payment under the IPPS and will not need to meet the requirement 
that it represents an advance that substantially improves, relative to 
technologies previously available, the diagnosis or treatment of 
Medicare beneficiaries. These technologies must still be within the 2-
to-3-year newness period to be considered ``new,'' and must also still 
meet the cost criterion.
    As discussed previously, in the FY 2023 IPPS/LTCH PPS final rule, 
we

[[Page 36106]]

finalized our proposal to publicly post online applications for new 
technology add-on payment beginning with FY 2024 applications (87 FR 
48986 through 48990). As noted in the FY 2023 IPPS/LTCH PPS final rule, 
we are continuing to summarize each application in this proposed rule. 
However, while we are continuing to provide discussion of the concerns 
or issues, we identified with respect to applications submitted under 
the alternative pathway, we are providing more succinct information as 
part of the summaries in the proposed and final rules regarding the 
applicant's assertions as to how the medical service or technology 
meets the applicable new technology add-on payment criteria. We refer 
readers to https://mearis.cms.gov/public/publications/ntap for the 
publicly posted FY 2025 new technology add-on payment applications and 
supporting information (with the exception of certain cost and volume 
information, and information or materials identified by the applicant 
as confidential or copyrighted), including tables listing the ICD-10-CM 
codes, ICD-10-PCS codes, and/or MS-DRGs related to the analyses of the 
cost criterion for certain technologies for the FY 2025 new technology 
add-on payment applications.
    We received 23 applications for new technology add-on payments for 
FY 2025 under the new technology add-on payment alternative pathway. As 
discussed previously, in the FY 2024 IPPS/LTCH PPS final rule (88 FR 
58948 through 58958), we finalized that beginning with the new 
technology add-on payment applications for FY 2025, for technologies 
that are not already FDA market authorized for the indication that is 
the subject of the new technology add-on payment application, 
applicants must have a complete and active FDA market authorization 
request at the time of new technology add-on payment application 
submission and must provide documentation of FDA acceptance or filing 
to CMS at the time of application submission, consistent with the type 
of FDA marketing authorization application the applicant has submitted 
to FDA. See Sec.  412.87(e) and further discussion in the FY 2024 IPPS/
LTCH PPS final rule (88 FR 58948 through 58958). Of the 23 applications 
received under the alternative pathway, seven applications were not 
eligible for consideration for new technology add-on payment because 
they did not meet these requirements; and two applicants withdrew their 
applications prior to the issuance of this proposed rule, including the 
withdrawal of the application for DefenCathTM (taurolidine/
heparin), which received conditional approval for new technology add-on 
payments for FY 2024, subsequently received FDA approval in November 
2023, and therefore was eligible to receive new technology add-on 
payments beginning with discharges on or after January 1, 2024. As 
discussed in section II.E.4. of this proposed rule, we are proposing to 
continue making new technology add-on payments for 
DefenCathTM (taurolidine/heparin) for FY 2025. Of the 
remaining 14 applications, 12 of the technologies received a 
Breakthrough Device designation from FDA. The remaining two 
applications were designated as a QIDP by FDA. We did not receive any 
applications for technologies approved through the LPAD pathway.
    In accordance with the regulations under Sec.  412.87(f)(2), 
applicants for new technology add-on payments for FY 2025 for 
Breakthrough Devices must have FDA marketing authorization by May 1 of 
the year prior to the beginning of the fiscal year for which the 
application is being considered. Under Sec.  412.87(f)(3), applicants 
for new technology add-on payments for FY 2025 for QIDPs and 
technologies approved under the LPAD pathway must have FDA marketing 
authorization by July 1 of the year prior to the beginning of the 
fiscal year for which the application is being considered. The policy 
finalized in the FY 2021 IPPS/LTCH PPS final rule (85 FR 58742) 
provides for conditional approval for a technology for which an 
application is submitted under the alternative pathway for certain 
antimicrobial products (QIDPs and LPADs) at Sec.  412.87(d) that does 
not receive FDA marketing authorization by July 1 prior to the 
particular fiscal year for which the applicant applied for new 
technology add-on payments, provided that the technology receives FDA 
marketing authorization before July 1 of the fiscal year for which the 
applicant applied for new technology add-on payments. We refer the 
reader to the FY 2021 IPPS/LTCH final rule for a complete discussion of 
this policy (85 FR 58737 through 58742).
    As we did in the FY 2024 IPPS/LTCH PPS proposed rule, for 
applications under the alternative new technology add-on payment 
pathway, in this proposed rule we are making a proposal to approve or 
disapprove each of these 14 applications for FY 2025 new technology 
add-on payments. Therefore, in this section of the preamble of this 
proposed rule, we provide background information on each alternative 
pathway application and propose whether or not each technology would be 
eligible for the new technology add-on payment for FY 2025. We refer 
readers to section II.H.8. of the preamble of the FY 2020 IPPS/LTCH PPS 
final rule (84 FR 42292 through 42297) and FY 2021 IPPS/LTCH PPS final 
rule (85 FR 58715 through 58733) for further discussion of the 
alternative new technology add-on payment pathways for these 
technologies.
a. Annalise Enterprise Computed Tomography Brain (CTB) Triage--
Obstructive Hydrocephalus (OH)
    Annalise-Ai Pty Ltd submitted an application for new technology 
add-on payments for the Annalise Enterprise CTB Triage--OH for FY 2025. 
According to the applicant, the Annalise Enterprise CTB Triage--OH is a 
medical device software application used to aid in the triage and 
prioritization of studies with features suggestive of obstructive 
hydrocephalus (OH). Per the applicant, the device analyzes studies 
using an artificial intelligence (AI) algorithm to identify suspected 
OH findings in non-contrast computed tomography (NCCT) brain scans and 
makes study-level output available to an order and imaging management 
system for worklist prioritization or triage.
    Please refer to the online application posting for the Annalise 
Enterprise CTB Triage--OH available at https://mearis.cms.gov/public/publications/ntap/NTP231017D5AA7, for additional detail describing the 
technology and how it is used.
    According to the applicant, the Annalise Enterprise CTB Triage--OH 
received Breakthrough Device designation from FDA on February 17, 2023, 
for use in the medical care environment to aid in triage and 
prioritization of studies with features suggestive of OH. The device 
analyzes studies using an AI algorithm to identify findings. It makes 
study-level output available to an order and imaging management system 
for worklist prioritization or triage. The applicant stated that the 
technology received 510(k) clearance from FDA on August 15, 2023, for 
the same indication consistent with the Breakthrough Device 
designation. Per the applicant, the Annalise Enterprise CTB Triage--OH 
was not immediately available for sale because there were additional 
steps to be completed following 510(k) clearance prior to the product 
becoming commercially available. According to the applicant, these 
additional steps involved generating a new unique device identifier 
(UDI) to incorporate the recently cleared finding for OH, integrating 
this UDI into the device, and

[[Page 36107]]

releasing it. Per the applicant, the Annalise Enterprise CTB Triage--OH 
became commercially available on October 10, 2023.
    According to the applicant, there are currently no ICD-10-PCS 
procedure codes to distinctly identify the Annalise Enterprise CTB 
Triage--OH. The applicant submitted a request for approval for a unique 
ICD-10-PCS procedure code for the Annalise Enterprise CTB Triage--OH 
beginning in FY 2025. The applicant provided a list of diagnosis codes 
that may be used to currently identify the indication for the Annalise 
Enterprise CTB Triage--OH under the ICD-10-CM coding system. Please 
refer to the online application posting for the complete list of ICD-
10-CM codes provided by the applicant.
    With respect to the cost criterion, the applicant provided three 
analyses to demonstrate that the technology meets the cost criterion. 
The applicant stated that for all three analyses, it used the 2021 
Standard Analytic Files (SAF) Limited Data Set (LDS) to identify the 
top admitting diagnosis codes for inpatient stays that were admitted 
from the emergency room (ER) and included a non-contrast CT head scan. 
Next, it searched the FY 2022 MedPAR data to identify applicable 
inpatient stays based on different sets of admitting diagnosis codes 
for each of the three analyses. The applicant explained that it used 
admitting diagnosis codes from the inpatient stays, rather than 
discharge diagnosis codes, because the Annalise Enterprise CTB Triage--
OH is an AI-based technology used to identify and prioritize patients 
suspected of OH. As a result, it will commonly be used in the ER before 
the doctor and/or the hospital has assigned the primary or secondary 
diagnosis for the inpatient stay. The applicant stated that admitting 
diagnosis codes may be better predictors for whether the Annalise 
Enterprise CTB Triage--OH service will be used, rather than primary or 
secondary diagnosis at discharge, which will likely represent 
information known after the procedure is performed. Per the applicant, 
for identifying the top admitting diagnosis codes, the inpatient stays 
were further narrowed down to only those where the patient had a 
physician claim during the inpatient stay or 1 day before for a non-
contrast CT head scan (defined as CPT codes 70450, 70480, 70486), or 
had an outpatient claim for a non-contrast CT head scan the day of 
admission or 1 day before. Each analysis followed the order of 
operations described in the table that follows later in this section.
    For the primary analysis, the applicant stated that it searched the 
FY 2022 MedPAR file for cases with emergency room charges (that is, 
emergency room charge amount greater than $0) and/or an inpatient 
admission type code (IP_ADMSN_TYPE_CD) equal to 1 for emergency, and 
reporting one of the top 25 diagnosis codes associated with 50% of all 
identified inpatient stays in the 2021 SAF. According to the applicant, 
it identified 2,206,036 claims mapping to 714 MS-DRGs, including MS-DRG 
871 (Septicemia or Severe Sepsis without MV >96 Hours with MCC), which 
represented 16% of identified cases. The applicant stated that it 
calculated a final inflated average case-weighted standardized charge 
per case of $80,407, which exceeded the average case-weighted threshold 
amount of $69,892.
    For the second analysis, the applicant stated that it conducted a 
sensitivity analysis using cases with emergency room charges (that is, 
emergency room charge amount greater than $0) and/or an inpatient 
admission type code (IP_ADMSN_TYPE_CD) equal to 1 for emergency, and 
reporting one of the top 186 admitting diagnosis codes associated with 
80% of all identified inpatient stays in the 2021 SAF LDS. The 
applicant noted that it identified 3,991,354 claims mapping to 739 MS-
DRGs, including MS-DRG 871 (Septicemia or Severe Sepsis without MV >96 
Hours with MCC), which represented 11% of identified cases. The 
applicant noted that it calculated a final inflated average case-
weighted standardized charge per case of $78,356, which exceeded the 
average case-weighted threshold amount of $68,660.
    For the third analysis, the applicant stated that it conducted a 
sensitivity analysis that identified cases using the same criteria as 
the primary analysis, and further limited it to cases that also 
incurred CT charges. Per the applicant, it performed this sensitivity 
analysis because although doctors are likely to order the Annalise AI 
technology when a NCCT head scan is performed and the patient is 
admitted through the emergency room, the MedPAR file variable for CT 
charges does not differentiate between contrast and NCCTs, or the area 
of the body where the CT is performed, and does not capture CT charges 
billed by physicians during the inpatient stay. As a result, it further 
limited the cases to those with charges for CT to assess if this would 
impact whether the technology would meet the cost criterion. Per the 
applicant, it identified 1,546,504 claims mapping to 702 MS-DRGs, 
including MS-DRG 871 (Septicemia or Severe Sepsis without MV >96 Hours 
with MCC), which represented 17% of identified cases. The applicant 
stated that it calculated a final inflated average case-weighted 
standardized charge per case of $89,176, which exceeded the average 
case-weighted threshold amount of $71,344.
    The applicant asserted that because the final inflated average 
case-weighted standardized charge per case exceeded the average case-
weighted threshold amount in all scenarios, the Annalise Enterprise CTB 
Triage--OH meets the cost criterion.
---------------------------------------------------------------------------

codes and MS-DRGs attachment included in the online posting for the 
technology.

[GRAPHIC] [TIFF OMITTED] TP02MY24.127

    According to the applicant, the technology is used to aid in the 
triage and prioritization of studies with features suggestive of OH. 
However, the diagnosis codes that the applicant used to identify 
eligible cases included non-neurologic diagnosis codes (for example, 
U071, R0602, J189). We question whether these diagnosis codes are 
applicable, and whether using neurologic diagnosis codes for diagnoses 
that exhibit symptoms similar to OH would more accurately identify 
eligible cases.
    Subject to the applicant adequately addressing this concern, we 
would agree that the technology meets the cost criterion and are 
proposing to approve the Annalise Enterprise CTB Triage--OH for new 
technology add-on payments for FY 2025.
    Based on preliminary information from the applicant at the time of 
this proposed rule, the applicant anticipated the total cost of the 
Annalise Enterprise CTB Triage--OH to the hospital to be $371.37 per 
patient. According to the applicant, hospitals acquire the Annalise 
Enterprise CTB Triage--OH system on a subscription-based model, with an 
annual cost of $180,000 per hospital. The applicant stated that the 
average cost per patient per hospital will vary by the volume of the 
NCCT cases for which the software is used. To determine the cost per 
case, the applicant used the following methodology:
    First, the applicant conducted market research to estimate the 
percent of NCCT cases where this software would likely be ordered, 
which was estimated at 50% of NCCT head scans for older patients (>65 
years of age) and 30% of NCCT head scans for younger patients (<65 
years of age).
    Second, the applicant used the 2021 SAF LDS to identify total NCCT 
scans by hospital. To represent the full Medicare fee-for-service 
population, the applicant multiplied total NCCT head scans at each 
hospital from the data by 20.
    Third, to calculate the total number of NCCT head scans for each 
hospital, the applicant assumed that 56.5% of all NCCT scans are for 
Medicare beneficiaries, based on literature on trends in the 
utilization of head CT scans in the United States.\118\

2022) Trends in inpatient utilization of head computerized 
tomography scans in the United States: A brief cross-sectional 
study. Cureus 14(6): e26018. DOI 10.7759/cureus.26018
---------------------------------------------------------------------------

    Fourth, to calculate the cost per case for each hospital, the 
applicant divided $180,000 by the estimated number of NCCT head scans 
analyzed by the technology for each hospital. Per the applicant, the 
average cost per case across all IPPS hospitals was then calculated at 
$371.37.
    The applicant asserted that calculating the cost per case across 
all IPPS hospitals was reasonable. The applicant noted that given its 
limited time on the market and low number of subscribers, it used all 
IPPS hospitals to calculate cost per case rather than

[[Page 36109]]

limiting the analysis to current subscribers. The applicant mentioned 
that for technologies that are commercially available for a longer 
period of time and with more subscribers, it may make sense to limit 
the cost per case analysis to hospitals that are current subscribers 
rather than using all IPPS hospitals in the calculation.
    As we noted in the FY 2021 IPPS/LTCH PPS final rule (85 FR 58630) 
and in the FY 2022 IPPS/LTCH PPS final rule (86 FR 44983), we 
understand that there are unique circumstances with respect to 
determining a cost per case for a technology that utilizes a 
subscription for its cost and we will continue to consider the issues 
relating to calculation of the cost per unit of technologies sold on a 
subscription basis as we gain more experience in this area. We continue 
to welcome comments from the public as to the appropriate method to 
determine a cost per case for such technologies, including comments on 
whether the cost analysis should be updated based on the most recent 
subscriber data for each year for which the technology may be eligible 
for add-on payment.
    We note that the cost information for this technology may be 
updated in the final rule based on revised or additional information 
CMS receives prior to the final rule. Under Sec.  412.88(a)(2), we 
limit new technology add-on payments to the lesser of 65% of the 
average cost of the technology, or 65% of the costs in excess of the 
MS-DRG payment for the case. As a result, we are proposing that the 
maximum new technology add-on payment for a case involving the use of 
the Annalise Enterprise CTB Triage--OH would be $241.39 for FY 2025 
(that is, 65% of the average cost of the technology).
    We invite public comments on whether the Annalise Enterprise CTB 
Triage--OH meets the cost criterion and our proposal to approve new 
technology add-on payments for the Annalise Enterprise CTB Triage--OH 
for FY 2025 for use in the medical care environment to aid in triage 
and prioritization of studies with features suggestive of OH.
b. ASTar[supreg] System
    Q-linea submitted an application for new technology add-on payments 
for the ASTar[supreg] System for FY 2025. According to the applicant, 
the ASTar[supreg] System is a fully automated system for rapid 
antimicrobial susceptibility testing (AST). The applicant stated that 
the proprietary AST technology is based on broth microdilution (BMD), 
optimized for high sensitivity and short time-to-result, delivering 
phenotypic AST with true minimum inhibitory concentration (MIC) results 
in approximately six hours.
    Please refer to the online application posting for the 
ASTar[supreg] System, available at https://mearis.cms.gov/public/publications/ntap/NTP231013T7Y5F, for additional detail describing the 
technology and how it is used.
    According to the applicant, the ASTar[supreg] System consists of 
the ASTar[supreg] Instrument and the ASTar[supreg] BC G-Kit. According 
to the applicant, the ASTar[supreg] Instrument and ASTar[supreg] BC G-
Kit, which includes the ASTar[supreg] BC G-Consumable Kit and the ASTar 
BC G-Frozen Insert, received Breakthrough Device designation from FDA 
on April 7, 2022. The ASTar[supreg] BC G-Kit is a multiplexed, in 
vitro, diagnostic test utilizing AST methods and is intended for use 
with the ASTar[supreg] Instrument. The ASTar[supreg] BC G-Kit is 
performed directly on positive blood cultures confirmed positive for 
Gram-negative bacilli only by Gram stain, and tests antimicrobial 
agents with nonfastidious and fastidious bacterial species. According 
to the applicant, its marketing authorization request for the 
ASTar[supreg] BC G-Kit has been accepted by FDA, and it anticipates a 
510(k) decision from FDA for the same indication consistent with the 
Breakthrough Device designation before May 1, 2024. The applicant 
stated that it anticipates the technology will be available on the 
market immediately after 510(k) clearance from FDA.
    According to the applicant, there are currently no ICD-10-PCS 
procedure codes to distinctly identify the ASTar[supreg] System. The 
applicant submitted a request for approval for a unique ICD-10-PCS 
procedure code for the ASTar[supreg] System beginning in FY 2025. The 
applicant provided a list of diagnosis codes that may be used to 
currently identify the indication for the ASTar[supreg] System under 
the ICD-10-CM coding system. Please refer to the online application 
posting for the complete list of ICD-10-CM codes provided by the 
applicant.
    With respect to the cost criterion, the applicant provided multiple 
analyses to demonstrate that it meets the cost criterion. Each analysis 
used different ICD-10-CM codes to identify potential cases in the FY 
2022 MedPAR file representing patients who may be eligible for the 
ASTar[supreg] System. According to the applicant, Cohort 1 comprised 
patients with non-sepsis infections and Cohort 2 consisted of patients 
with sepsis resulting from bacteria identifiable by the ASTar[supreg] 
System. The applicant explained that these scenarios were separated as 
the applicant believed that charges and MS-DRG assignments may differ 
due to the resources required to treat sepsis patients compared to 
those required for less severe infections. Finally, Cohort 3 included 
all ICD-10-CM codes from Cohorts 1 and 2 because the applicant stated 
that the ASTar[supreg] System may be used to identify any infection 
caused by the bacteria listed in Cohorts 1 and 2. The applicant stated 
that in all three cohorts, the patients mapped to a large number of MS-
DRGs based on the listed ICD-10-CM codes. Therefore, in the analyses, 
the applicant only included the most common MS-DRGs, that is, the MS-
DRGs containing at least 1 percent of the potential case volume within 
each of the three cohorts, as these are the MS-DRGs to which potential 
ASTar[supreg] System cases would most closely map. The applicant used 
the inclusion/exclusion criteria described in the table that follows 
later in this section to identify claims for each cohort. Each analysis 
followed the order of operations described in the table that follows 
later in this section.
    For Cohort 1, the applicant identified 440,838 claims mapping to 14 
MS-DRGs, including MS-DRG 871 (Septicemia or Severe Sepsis with MV >96 
Hours with MCC) representing 25% of identified cases, and calculated a 
final inflated average case-weighted standardized charge per case of 
$85,525, which exceeded the average case-weighted threshold amount of 
$70,398.
    For Cohort2, the applicant identified 224,825 claims mapping to 7 
MS-DRGs, including MS-DRG 871 (Septicemia or Severe Sepsis with MV >96 
Hours with MCC) representing 54% of identified cases, and calculated a 
final inflated average case-weighted standardized charge per case of 
$99,508, which exceeded the average case-weighted threshold amount of 
$82,171.
    For Cohort3, the applicant identified 603,877 claims mapping to 13 
MS-DRGs, including MS-DRG 871 (Septicemia or Severe Sepsis with MV >96 
Hours with MCC) representing 34% of identified cases, and calculated a 
final inflated average case-weighted standardized charge per case of 
$88,395

[[Page 36110]]

which exceeded the average case-weighted threshold amount of $73,727.
    Because the final inflated average case-weighted standardized 
charge per case exceeded the average case-weighted threshold amount in 
all the three cohorts, the applicant asserted that the ASTar[supreg] 
System meets the cost criterion.

    We agree with the applicant that the ASTar[supreg] System meets the 
cost criterion and are therefore proposing to approve the ASTar[supreg] 
System for new technology add-on payments for FY 2025, subject to the 
technology receiving FDA marketing authorization as a Breakthrough 
Device for the indication corresponding to the Breakthrough Device 
designation by May 1, 2024.
    Based on preliminary information from the applicant at the time of 
this proposed rule, the applicant anticipated the operating cost of the 
ASTar[supreg] System to the hospital to be $150 per patient, based on 
the operating component ASTar[supreg] BC G-Kit (composed of the 
ASTar[supreg] BC G-Consumable Kit ($141) and ASTar BC G-Frozen Insert 
($9)). The applicant also noted a capital cost of $200,000 for the 
ASTar[supreg] Instrument. Because section 1886(d)(5)(K)(i) of the Act 
requires that the Secretary establish a mechanism to recognize the 
costs of new medical services or technologies under the payment system 
established under that subsection, which establishes the system for 
payment of the operating costs of inpatient hospital services, we do 
not include capital costs in the add-on payments for a new medical 
service or technology or make new technology add-on payments under the 
IPPS for capital-related costs (86 FR 45145). As noted, the applicant 
stated that the cost of the ASTar[supreg] Instrument is a capital cost. 
Therefore, it appears that this component is not eligible for new 
technology add-on payment because, as discussed in prior rulemaking and 
as noted, we only make new technology add-on payments for operating 
costs (72 FR 47307 through 47308). We note that any new technology add-
on payment for the ASTar[supreg] System would include only the cost of 
ASTar[supreg] BC G-Kit ($150). We note that the cost information for 
this technology may be updated in the final rule based on revised or 
additional information CMS receives prior to the final rule. Under 
Sec.  412.88(a)(2), we limit

[[Page 36111]]

new technology add-on payments to the lesser of 65% of the average cost 
of the technology, or 65% of the costs in excess of the MS-DRG payment 
for the case. As a result, we are proposing that the maximum new 
technology add-on payment for a case involving the use of the 
ASTar[supreg] System would be $97.50 for FY 2025 (that is, 65% of the 
average cost of the technology).
    We invite public comments on whether the ASTar[supreg] System meets 
the cost criterion and our proposal to approve new technology add-on 
payments for the ASTar[supreg] System for FY 2025, subject to the 
technology receiving FDA marketing authorization as a Breakthrough 
Device for the indication corresponding to the Breakthrough Device 
designation by May 1, 2024.
c. Cefepime-Taniborbactam
    Venatorx Pharmaceuticals, Inc. submitted an application for new 
technology add-on payments for cefepime-taniborbactam for FY 2025. 
According to the applicant, cefepime-taniborbactam is an 
investigational [beta]-lactam antibiotic/[beta]-lactamase inhibitor 
combination under development for the treatment of complicated urinary 
tract infections (cUTI), including pyelonephritis, melioidosis, and 
hospital-acquired bacterial pneumonia (HABP)/ventilator-associated 
bacterial pneumonia (VABP).
    Please refer to the online application posting for cefepime-
taniborbactam, available at https://mearis.cms.gov/public/publications/ntap/NTP2310168RYEB, for additional detail describing the technology 
and the disease treated by the technology.
    According to the applicant, cefepime-taniborbactam received QIDP 
designation from FDA on February 4, 2022, for cUTI, complicated intra-
abdominal infections (cIAI), HABP, VABP, and melioidosis. The applicant 
stated that it is seeking approval from FDA for the treatment of 
patients 18 years of age and older with cUTI, including pyelonephritis 
caused by designated susceptible gram-negative bacteria, including 
cases with concurrent bacteremia. According to the applicant, its 
marketing request for cefepime-taniborbactam has been filed by FDA, and 
it anticipates an NDA decision before July 1, 2024. According to the 
applicant, cefepime-taniborbactam is not expected to be commercially 
available immediately after FDA approval due to manufacturing readiness 
activities and the expected commercial availability date is October 1, 
2024. We note that, as an application submitted under the alternative 
pathway for certain antimicrobial products at Sec.  412.87(d), 
cefepime-taniborbactam is eligible for conditional approval for new 
technology add-on payments if it does not receive FDA marketing 
authorization by July 1, 2024, provided that the technology receives 
FDA marketing authorization before July 1 of the fiscal year for which 
the applicant applied for new technology add-on payments (that is, July 
1, 2025), as provided in Sec.  412.87(f)(3). To estimate the average 
dosage per patient, the applicant calculated a weighted average 
duration of treatment. Per the applicant, based on the dosing schedule, 
a patient receives approximately 3 doses per 24 hours. The applicant 
noted for 48 patients with bacteremia, the average length of stay was 
10.9 days, and for 392 patients without bacteremia, the average length 
of stay was 7.2 days, which led to a weighted average treatment 
duration of 7.5 days and 23 doses per average inpatient stay.
    According to the applicant, there are currently no ICD-10-PCS 
procedure codes to distinctly identify cefepime-taniborbactam. The 
applicant submitted a request for approval for a unique ICD-10-PCS 
procedure code for cefepime-taniborbactam beginning in FY 2025. The 
applicant stated that ICD-10-CM diagnosis codes for the treatment of 
cUTI may be used to currently identify the indication for cefepime-
taniborbactam under the ICD-10-CM coding system. Please refer to the 
online application posting for the complete list of ICD-10-CM codes 
provided by the applicant.
    With respect to the cost criterion, to identify potential cases 
representing patients who may be eligible for cefepime-taniborbactam, 
the applicant searched the FY 2022 MedPAR file for claims that had one 
of the ICD-10-CM codes reflecting conditions that would be considered 
an indication for cefepime-taniborbactam for the treatment of cUTI. 
Using the inclusion/exclusion criteria described in the following 
table, the applicant identified 833,530 claims mapping to 526 MS-DRGs, 
including MS-DRG 871 (Septicemia or Severe Sepsis without MV >96 Hours 
with MCC), 690 (Kidney and Urinary Tract Infections without MCC), and 
689 (Kidney and Urinary Tract Infections with MCC). The applicant 
followed the order of operations described in the following table and 
calculated a final inflated average case-weighted standardized charge 
per case of $91,218, which exceeded the average case-weighted threshold 
amount of $71,256. Because the final inflated average case-weighted 
standardized charge per case exceeded the average case-weighted 
threshold amount, the applicant asserted that cefepime-taniborbactam 
meets the cost criterion.

    We agree with the applicant that cefepime-taniborbactam meets the 
cost criterion and are therefore proposing to approve cefepime-
taniborbactam for new technology add-on payments for FY 2025, subject 
to the technology receiving FDA marketing authorization as a QIDP for 
the indication corresponding to the QIDP designation by July 1, 2024. 
As an application submitted under the alternative pathway for certain 
antimicrobial products at Sec.  412.87(d), cefepime-taniborbactam is 
eligible for conditional approval for new technology add-on payments if 
it does not receive FDA marketing authorization by July 1, 2024, 
provided that the technology receives FDA marketing authorization 
before July 1 of the fiscal year for which the applicant applied for 
new technology add-on payments (that is, July 1, 2025), as provided in 
Sec.  412.87(f)(3). If cefepime-taniborbactam receives FDA marketing 
authorization before July 1, 2025, the new technology add-on payment 
for cases involving the use of this technology would be made effective 
for discharges beginning in the first quarter after FDA marketing 
authorization is granted. If FDA marketing authorization is received on 
or after July 1, 2025, no new technology add-on payments would be made 
for cases involving the use of cefepime-taniborbactam for FY 2025.
    The applicant has not provided an estimate for the cost of 
cefepime-taniborbactam at the time of this proposed rule. Per the 
applicant, based on the dosing schedule, a patient receives 
approximately 3 doses per 24 hours. The applicant noted for 48 patients 
with bacteremia, the average length of stay was 10.9 days, and for 392 
patients without bacteremia, the average length of stay was 7.2 days, 
which led to a weighted average treatment duration of 7.5 days and 23 
doses per average inpatient stay. We expect the applicant to submit 
cost information prior to the final rule, and we will provide an update 
regarding the new technology add-on payment amount for the technology, 
if approved, in the final rule. Any new technology add-on payment for 
cefepime-taniborbactam would be subject to our policy under Sec.  
412.88(a)(2)(ii)(B) where we limit new technology add-on payment for 
QIDPs to the lesser of 75% of the average cost of the technology, or 
75% of the costs in excess of the MS-DRG payment for the case.
    We invite public comments on whether cefepime-taniborbactam meets 
the cost criterion and our proposal to approve new technology add-on 
payments for cefepime-taniborbactam for FY 2025, subject to the 
technology receiving FDA marketing authorization consistent with its 
QIDP designation by July 1, 2024.
d. Edwards EVOQUE\TM\ Tricuspid Valve Replacement System (Transcatheter 
Tricuspid Valve Replacement System)
    Edwards Lifesciences LLC submitted an application for new 
technology add-on payments for the Edwards EVOQUE\TM\ Tricuspid Valve 
Replacement System (``EVOQUE\TM\ System'') for FY 2025. According to 
the applicant, the EVOQUE\TM\ System is a new, transcatheter treatment 
option for patients with at least severe tricuspid regurgitation. Per 
the applicant, the EVOQUE\TM\ System is designed to replace the native 
tricuspid valve and consists of a transcatheter bioprosthetic valve, a 
catheter-based delivery system, and supporting accessories.
    Please refer to the online application posting for the Edwards 
EVOQUE\TM\ Tricuspid Valve Replacement System, available at https://mearis.cms.gov/public/publications/ntap/NTP231013MRRBG, for additional 
detail describing the technology and the condition treated by the 
technology.
    According to the applicant, the EVOQUE\TM\ System received 
Breakthrough Device designation from FDA on December 18, 2019, for the 
treatment of patients with symptomatic moderate or above tricuspid 
regurgitation. The applicant stated that the technology received 
premarket approval from FDA on February 1, 2024 for a narrower 
indication for use, for the improvement of health status in patients 
with symptomatic severe tricuspid regurgitation despite optimal medical

[[Page 36113]]

therapy, for whom tricuspid valve replacement is deemed appropriate by 
a heart team. Since the indication for which the applicant received 
premarket approval is included within the scope of the Breakthrough 
Device designation, it appears that the PMA indication is appropriate 
for consideration for new technology add-on payment under the 
alternative pathway criteria. According to the applicant, the 
EVOQUE\TM\ System was commercially available immediately after FDA 
approval.
    According to the applicant, there are currently no ICD-10-PCS 
procedure codes to distinctly identify the EVOQUE\TM\ System. The 
applicant submitted a request for approval for a unique ICD-10-PCS 
procedure code for the EVOQUE\TM\ System beginning in FY 2025. The 
applicant stated that ICD-10-CM diagnosis codes I07.1 (Rheumatic 
tricuspid insufficiency), I07.2 (Rheumatic tricuspid stenosis and 
insufficiency), I36.1 (Nonrheumatic tricuspid (valve) insufficiency), 
and I36.2 (Nonrheumatic tricuspid (valve) stenosis with insufficiency) 
may be used to currently identify the indication for the EVOQUE\TM\ 
System under the ICD-10-CM coding system.
    With respect to the cost criterion, the applicant provided two 
analyses to demonstrate that the technology meets the cost criterion. 
To identify potential cases representing patients who may be eligible 
for the EVOQUE\TM\ System, each analysis used the same ICD-10-CM 
diagnosis codes in different positions, with and without selected ICD-
10-PCS procedure codes, to identify relevant cases in the FY 2022 
MedPAR file. Each analysis followed the order of operations described 
in the table that follows later in this section.
    For the first analysis, the applicant searched for cases assigned 
to MS-DRGs 266 (Endovascular Cardiac Valve Replacement and Supplement 
Procedures with MCC) and 267 (Endovascular Cardiac Valve Replacement 
and Supplement Procedures without MCC) that included one of the four 
ICD-10-CM diagnosis codes in any position, as listed in the table that 
follows later in this section. The applicant used the inclusion/
exclusion criteria described in the table that follows later in this 
section. Under this analysis, the applicant identified 2,728 claims 
mapping to the two MS-DRGs and calculated a final inflated average 
case-weighted standardized charge per case of $267,720, which exceeded 
the average case-weighted threshold amount of $194,848.
    For the second analysis, the applicant searched for the cases that 
included any of the ICD-10-PCS codes for percutaneous repair or 
replacement of the tricuspid valve in any position, in combination with 
one of the four ICD-10-CM codes for tricuspid valve insufficiency as 
the primary diagnosis, as listed in the table that follows later in 
this section. The applicant used the inclusion/exclusion criteria 
described in the table that follows later in this section. Under this 
analysis, the applicant identified 198 claims mapping to 6 MS-DRGs and 
calculated a final inflated average case-weighted standardized charge 
per case of $327,236, which exceeded the average case-weighted 
threshold amount of $219,225.
    Because the final inflated average case-weighted standardized 
charge per case exceeded the average case-weighted threshold amount in 
all scenarios, the applicant asserted that the EVOQUE\TM\ System meets 
the cost criterion.

[[Page 36114]]

[GRAPHIC] [TIFF OMITTED] TP02MY24.130

    We agree with the applicant that the EVOQUE\TM\ System meets the 
cost criterion and are therefore proposing to approve the EVOQUE\TM\ 
System for new technology add-on payments for FY 2025.
    Based on preliminary information from the applicant at the time of 
this proposed rule, the applicant anticipated the total cost of the 
EVOQUE\TM\ System to the hospital to be $49,000 per patient, which 
includes the following components: the EVOQUE\TM\ Tricuspid Delivery 
System, the EVOQUE\TM\ Dilator Kit, the EVOQUE\TM\ Loading System, the 
Stabilizer, Base, and Plate, and the EVOQUE\TM\ Valve. The applicant 
noted that the listed

[[Page 36115]]

components of the EVOQUETM System are sold together as one 
unit because they are all needed to perform the procedure, are all 
single patient use, and are not sold separately. We note that the cost 
information for this technology may be updated in the final rule based 
on revised or additional information CMS receives prior to the final 
rule. Under Sec.  412.88(a)(2), we limit new technology add-on payments 
to the lesser of 65% of the average cost of the technology, or 65% of 
the costs in excess of the MS-DRG payment for the case. As a result, we 
are proposing that the maximum new technology add-on payment for a case 
involving the use of the EVOQUE\TM\ System would be $31,850 for FY 2025 
(that is, 65% of the average cost of the technology).
    We invite public comments on whether the EVOQUE\TM\ System meets 
the cost criterion and our proposal to approve new technology add-on 
payments for the EVOQUE\TM\ System for FY 2025 for the improvement of 
health status in patients with symptomatic severe tricuspid 
regurgitation despite optimal medical therapy, for whom tricuspid valve 
replacement is deemed appropriate by a heart team.
e. GORE[supreg] EXCLUDER[supreg] Thoracoabdominal Branch Endoprosthesis 
(TAMBE Device)
    W.L. Gore & Associates, Inc. submitted an application for new 
technology add-on payments for the TAMBE Device for FY 2025. According 
to the applicant, the TAMBE Device is used for endovascular repair in 
patients with thoracoabdominal aortic aneurysms (TAAA) and high-
surgical risk patients with pararenal abdominal aortic aneurysms (PAAA) 
who have appropriate anatomy. Per the applicant, the TAMBE Device is 
comprised of multiple required components, including: (1) an Aortic 
Component, (2) Branch Components, (3) a Distal Bifurcated Component, 
and (4) Contralateral Leg Component. According to the applicant, these 
components together comprise the TAMBE Device.
    Please refer to the online application posting for the GORE[supreg] 
EXCLUDER[supreg] Thoracoabdominal Branch Endoprosthesis (TAMBE Device), 
available at https://mearis.cms.gov/public/publications/ntap/NTP231016DYQQX, for additional detail describing the technology and the 
condition treated by the technology.
    According to the applicant, the TAMBE Device received Breakthrough 
Device designation from FDA on October 1, 2021, for endovascular repair 
of thoracoabdominal and pararenal aneurysms in the aorta in patients 
who have appropriate anatomy. According to the applicant, the TAMBE 
Device received premarket approval (PMA) from FDA on January 12, 2024, 
for a slightly narrower indication for use, namely, TAAA and high-
surgical risk patients with PAAA who have appropriate anatomy. Since 
the indication for which the applicant received premarket approval is 
included within the scope of the Breakthrough Device designation, it 
appears that the PMA indication is appropriate for consideration for 
new technology add-on payment under the alternative pathway criteria. 
According to the applicant, the TAMBE Device is not yet available for 
sale due to the required lead time to train physicians on the TAMBE 
Device, and the first commercial device will only be implanted May 1, 
2024 or later. We are interested in additional information regarding 
the delay in the technology's market availability, as we question 
whether the date the device first became available for sale would be 
the same as the date the first commercial device is implanted.
    According to the applicant, there are currently no ICD-10-PCS 
procedure codes to distinctly identify the TAMBE Device. The applicant 
submitted a request for approval for a unique ICD-10-PCS procedure code 
for the TAMBE Device beginning in FY 2025. The applicant provided a 
list of diagnosis codes that may be used to currently identify the 
proposed indication for the TAMBE Device under the ICD-10-CM coding 
system. Please refer to the online application posting for the complete 
list of ICD-10-CM codes provided by the applicant.
    With respect to the cost criterion, to identify potential cases 
representing patients who may be eligible for the TAMBE Device, the 
applicant searched the FY 2022 MedPAR file for claims that had at least 
one of the ICD-10-CM codes and at least one of the ICD-10-PCS codes as 
listed in the following table. Using the inclusion/exclusion criteria 
described in the following table, the applicant identified 1,005 claims 
mapping to 19 MS-DRGs, including MS-DRG 269 (Aortic and Heart Assist 
Procedures except Pulsation Balloon without MCC), which represented 
54.5% of the identified cases. The applicant followed the order of 
operations described in the following table and calculated a final 
inflated average case-weighted standardized charge per case of 
$448,347, which exceeded the average case-weighted threshold amount of 
$185,799. Because the final inflated average case-weighted standardized 
charge per case exceeded the average case-weighted threshold amount, 
the applicant asserted that the TAMBE Device meets the cost criterion.

    We agree with the applicant that the TAMBE Device meets the cost 
criterion and are therefore proposing to approve the TAMBE Device for 
new technology add-on payments for FY 2025.
    Based on preliminary information from the applicant at the time of 
this proposed rule, the applicant anticipated the total cost of the 
TAMBE Device to the hospital to be $72,675 per patient. Per the 
applicant, the TAMBE Device has a number of required components, 
including the aortic component ($29,000), branch components ($3,355), 
distal bifurcated component (DBC) ($10,758), DBC extender component 
($3,037), contralateral leg endoprosthesis ($4,390), and iliac extender 
endoprosthesis ($3,037). The applicant stated that the actual type and 
number of components used varies by patient depending on their anatomy 
and the extent of the patient's aneurysm. The applicant determined the 
number and types of components that were used in an average patient 
based on a multicenter pivotal clinical trial conducted predominantly 
in the U.S. and calculated the case cost per component. We note that 
the cost information for this technology may be updated in the final 
rule based on revised or additional information CMS receives prior to 
the final rule. Under Sec.  412.88(a)(2), we limit new technology add-
on payments to the lesser of 65% of the average cost of the technology, 
or 65% of the costs in excess of the MS-DRG payment for the case. As a 
result, we are proposing that the maximum new technology add-on payment 
for a case involving the use of the TAMBE Device would be $47,238.75 
for FY 2025 (that is, 65% of the average cost of the technology).
    We invite public comments on whether the TAMBE Device meets the 
cost criterion and our proposal to approve new technology add-on 
payments for the TAMBE Device for FY 2025, for endovascular repair in 
patients with thoracoabdominal aortic aneurysms and high-surgical risk 
patients with pararenal aortic aneurysms who have appropriate anatomy.
f. LimFlowTM System
    LimFlow Inc. submitted an application for new technology add-on 
payments for the LimFlowTM System for FY 2025. According to 
the applicant, the LimFlowTM System is a single-use, medical 
device system designed to treat patients who have chronic limb-
threatening ischemia with no suitable endovascular or surgical 
revascularization options and are at risk of major amputation. Per the 
applicant, the LimFlowTM System consists of LimFlow's 
Cylindrical and Conical Stent Grafts that are used in conjunction with 
a LimFlowTM Arterial Catheter, a LimFlowTM Venous 
Catheter, and a LimFlowTM Valvulotome. According to

[[Page 36117]]

the applicant, the LimFlowTM System is used for 
transcatheter arterialization of the deep veins, a minimally invasive 
procedure that aims to restore blood flow to the ischemic foot by 
diverting a stream of oxygenated blood through tibial veins in order to 
permanently bypass heavily calcified and severely stenotic arteries 
defined as unreconstructable. We note that LimFlow Inc. submitted an 
application for new technology add-on payments for the 
LimFlowTM System for FY 2024 as summarized in the FY 2024 
IPPS/LTCH PPS proposed rule (88 FR 26938 through 26940), but the 
technology did not meet the applicable deadline of July 1, 2023 for FDA 
approval or clearance of the technology and, therefore, was not 
eligible for consideration for new technology add-on payments for FY 
2024 (88 FR 58919).
    Please refer to the online application posting for the 
LimFlowTM System, available at https://mearis.cms.gov/public/publications/ntap/NTP23101627LXC, for additional detail 
describing the technology and the condition treated by the technology.
    According to the applicant, the LimFlowTM System 
received Breakthrough Device designation from FDA on October 3, 2017, 
for the treatment of critical limb ischemia by minimally invasively 
creating an arterio-venous bypass graft to produce the venous 
arterialization procedure in the below-the-knee vasculature. The 
applicant stated that the technology was granted premarket approval 
from FDA on September 11, 2023, for patients who have chronic limb-
threatening ischemia with no suitable endovascular or surgical 
revascularization options and are at risk of major amputation. Since 
the indication for which the applicant received premarket approval is 
considered equivalent to the Breakthrough Device designation, it 
appears that the premarket approval indication is appropriate for 
consideration for new technology add-on payment under the alternative 
pathway criteria. Per the applicant, the LimFlowTM System 
was not immediately available for sale because inventory build and ramp 
for commercial sales was set to commence following FDA approval to 
allow time for the conduct of surgeon training and medical education on 
patient selection, indications, and surgical technique. The applicant 
stated that the technology became commercially available on November 1, 
2023.
    The applicant provided a list of ICD-10-PCS codes that, effective 
October 1, 2018, can be used to uniquely describe procedures involving 
the use of the LimFlowTM System under the ICD-10-PCS coding 
system. Please see the online posting for the LimFlowTM 
System for the complete list of ICD-10-PCS codes provided by the 
applicant. The applicant provided a list of diagnosis codes that may be 
used to currently identify the indication for the LimFlowTM 
System under the ICD-10-CM coding system. Please refer to the online 
application posting for the complete list of ICD-10-CM codes provided 
by the applicant.
    With respect to the cost criterion, the applicant provided three 
analyses to demonstrate that it meets the cost criterion. Each analysis 
used the same ICD-10-PCS codes to identify potential cases representing 
patients who may be eligible for the LimFlowTM System. The 
applicant stated that the selected claims represent the exact 
situations in which the LimFlowTM System would be used and 
represent the cost of care associated with the use of the 
LimFlowTM System. The applicant utilized a different year of 
MedPAR data in each analysis. According to the applicant, it used 
multiple years of data because the case count in each individual year 
was low. The applicant imputed a value of 11 cases for MS-DRGs with 
less than 11 cases. Each analysis followed the order of operations 
described in the table that follows later in this section.
    For the first analysis, the applicant searched FY 2022 MedPAR data 
for claims reporting at least one of the ICD-10-PCS codes listed in the 
table that follows later in this section to identify cases that may be 
eligible for the LimFlowTM System. The applicant used the 
inclusion/exclusion criteria described in the table that follows later 
in this section. Under this analysis, the applicant identified 88 
claims mapping to 8 MS-DRGs, with none exceeding more than 13% of the 
total identified cases. The applicant calculated a final inflated 
average case-weighted standardized charge per case of $307,461 which 
exceeded the average case-weighted threshold amount of $124,971.
    For the second analysis, the applicant searched FY 2021 MedPAR data 
for claims reporting at least one of the ICD-10-PCS codes listed in the 
table that follows later in this section to identify cases that may be 
eligible for the LimFlowTM System. The applicant used the 
inclusion/exclusion criteria described in the table that follows later 
in this section. Under this analysis, the applicant identified 111 
claims mapping to 10 MS-DRGs, with none exceeding more than 11% of the 
total identified cases. The applicant calculated a final inflated 
average case-weighted standardized charge per case of $277,454, which 
exceeded the average case-weighted threshold amount of $116,278.
    For the third analysis, the applicant searched FY 2020 MedPAR data 
for claims reporting at least one of the ICD-10-PCS codes listed in the 
table that follows later in this section to identify cases that may be 
eligible for the LimFlowTM System. The applicant used the 
inclusion/exclusion criteria described in the table that follows later 
in this section. Under this analysis, the applicant identified 99 
claims mapping to 9 MS-DRGs, with none exceeding more than 12% of the 
total identified cases. The applicant calculated a final inflated 
average case-weighted standardized charge per case of $273,638 which 
exceeded the average case-weighted threshold amount of $125,153.
    Because the final inflated average case-weighted standardized 
charge per case exceeded the average case-weighted threshold amount in 
all scenarios, the applicant asserted that the LimFlowTM 
System meets the cost criterion.

    We agree with the applicant that the LimFlowTM System 
meets the cost criterion and are therefore proposing to approve the 
LimFlowTM System for new technology add-on payments for FY 
2025.
    Based on preliminary information from the applicant at the time of 
this proposed rule, the applicant anticipated the total cost of the 
LimFlowTM System to the hospital to be $25,000 per patient. 
According to the applicant, the LimFlowTM System is sold as 
a system, as such, the components of the LimFlowTM System 
are not priced or sold to hospitals independently. The applicant stated 
that all components of the LimFlowTM System are single-use 
and the entire system is an operating cost. We note that the cost 
information for this technology may be updated in the final rule based 
on revised or additional information CMS receives prior to the final 
rule. Under Sec.  412.88(a)(2), we limit new technology add-on payments 
to the lesser of 65% of the average cost of the technology, or 65% of 
the costs in excess of the MS-DRG payment for the case. As a result, we 
are proposing that the maximum new technology add-on payment for a case 
involving the use of the LimFlowTM System would be $16,250 
for FY 2025 (that is, 65% of the average cost of the technology).
    We invite public comments on whether the LimFlowTM 
System meets the cost criterion and our proposal to approve new 
technology add-on payments for the LimFlowTM System for FY 
2025 for patients who have chronic limb-threatening ischemia with no 
suitable endovascular or surgical revascularization options and are at 
risk of major amputation.
g. ParadiseTM Ultrasound Renal Denervation System
    ReCor Medical submitted an application for new technology add-on

[[Page 36119]]

payments for the ParadiseTM Ultrasound Renal Denervation 
System for FY 2025. According to the applicant, the 
ParadiseTM Ultrasound Renal Denervation System is an 
endovascular catheter-based system that delivers SonoWave360\TM\ 
ultrasound energy circumferentially, thermally ablating and disrupting 
overactive renal sympathetic nerves to lower blood pressure in adult 
(>=22 years of age) patients with uncontrolled hypertension who may be 
inadequately responsive to or who are intolerant to anti-hypertensive 
medications.
    Please refer to the online application posting for the 
ParadiseTM Ultrasound Renal Denervation System, available at 
https://mearis.cms.gov/public/publications/ntap/NTP23101772HBQ, for 
additional detail describing the technology and the condition treated 
by the technology.
    According to the applicant, the ParadiseTM Ultrasound 
Renal Denervation System received Breakthrough Device designation from 
FDA on December 4, 2020, for reducing blood pressure in adult (>=22 
years of age) patients with uncontrolled hypertension, who may be 
inadequately responsive to, or who are intolerant to anti-hypertensive 
medications. The applicant received FDA premarket approval for the 
technology on November 7, 2023, for reducing blood pressure as an 
adjunctive treatment in hypertension patients in whom lifestyle 
modifications and antihypertensive medications do not adequately 
control blood pressure. Because we consider the indication for which 
the applicant received premarket approval to be within the scope of the 
Breakthrough Device designation, and FDA considers this marketing 
authorization to be for the Breakthrough Device designation,\123\ it 
appears that the premarket approval indication is appropriate for 
consideration for new technology add-on payment under the alternative 
pathway criteria. According to the applicant, the technology was 
commercially available immediately after FDA approval.

https://www.fda.gov/medical-devices/how-study-and-market-your-device/breakthrough-devices-program.
---------------------------------------------------------------------------

    The applicant stated that effective October 1, 2023, the following 
ICD-10-PCS code may be used to uniquely describe procedures involving 
the use of the ParadiseTM Ultrasound Renal Denervation 
System: X051329 (Destruction of renal sympathetic nerve(s) using 
ultrasound ablation, percutaneous approach, new technology group 9). 
The applicant stated that ICD-10-CM codes I10 (Essential (primary) 
hypertension), I15.1 (Hypertension secondary to other renal disorders), 
I15.8 (Other secondary hypertension), I15.9 (Secondary hypertension, 
unspecified), and I1A.0 (Resistant hypertension) may be used to 
currently identify the indication for the ParadiseTM 
Ultrasound Renal Denervation System under the ICD-10-CM coding system.
    With respect to the cost criterion, the applicant provided multiple 
analyses to demonstrate that it meets the cost criterion. Each analysis 
used different MS-DRGs and/or ICD-10-CM codes to identify potential 
cases representing patients who may be eligible for the 
ParadiseTM Ultrasound Renal Denervation System. The 
applicant explained that it used different codes to demonstrate 
different cohorts that may be eligible for the technology. Each 
analysis followed the order of operations described in the table that 
follows later in this section.
    For the first analysis, the applicant searched the FY 2022 MedPAR 
file for all cases that map to MS-DRG 264 (Other Circulatory System 
O.R. Procedures). The applicant stated that medical MS-DRGs 304 and 305 
(Hypertension with MCC and without MCC) are specific to hypertension. 
However, given the nature of the procedure, the applicant's expectation 
is that the DRG Grouper logic would assign potential cases representing 
patients who may be eligible for the ParadiseTM Ultrasound 
Renal Denervation System to a surgical MS-DRG. To identify the surgical 
MS-DRG, the applicant identified ICD-10-PCS code 015M3ZZ (Destruction 
of abdominal sympathetic nerve, percutaneous approach) as the procedure 
most similar to the procedure performed using the ParadiseTM 
Ultrasound Renal Denervation System, and determined the specific MS-DRG 
to which that ICD-10-PCS code maps. The applicant used the inclusion/
exclusion criteria described in the table that follows later in this 
section. Under this analysis, the applicant identified 7,064 claims 
mapping to MS-DRG 264 (Other Circulatory System O.R. Procedures) and 
calculated a final inflated average case-weighted standardized charge 
per case of $357,807, which exceeded the average case-weighted 
threshold amount of $98,708.
    For the second analysis, as a sensitivity analysis the applicant 
searched the FY 2022 MedPAR file for all cases that map to MS-DRGs 304 
or 305 (Hypertension with MCC and without MCC), which are specific to 
hypertension. The applicant used the inclusion/exclusion criteria 
described in the table that follows later in this section. Under this 
analysis, the applicant identified 32,433 claims mapping to MS-DRG 304 
(Hypertension with MCC) or 305 (Hypertension without MCC) and 
calculated a final inflated average case-weighted standardized charge 
per case of $268,298, which exceeded the average case-weighted 
threshold amount of $46,986.
    For the third analysis, the applicant provided a sensitivity 
analysis that combined the first and second scenario together for a 
broader list of MS-DRGs. The applicant used the inclusion/exclusion 
criteria described in the table that follows later in this section. 
Under this analysis, the applicant identified 39,497 claims mapping to 
MS-DRGs 264 (Other Circulatory System O.R. Procedures), 304 
(Hypertension with MCC), or 305 (Hypertension without MCC) and 
calculated a final inflated average case-weighted standardized charge 
per case of $284,306, which exceeded the average case-weighted 
threshold amount of $56,237.
    For the fourth analysis, the applicant performed a sensitivity 
analysis to subset the cases assigned to MS-DRG 264 (Other Circulatory 
System O.R. Procedures) to those reporting the following ICD-10-CM 
codes: I10 (Essential (primary) hypertension), I15.1 (Hypertension 
secondary to other renal disorders), I15.8 (Other secondary 
hypertension), or I15.9 (Secondary hypertension, unspecified) in any 
position. The applicant used the inclusion/exclusion criteria described 
in the table that follows later in this section. Under this analysis, 
the applicant identified 1,477 claims mapping to MS-DRG 264 (Other 
Circulatory System O.R. Procedures) and calculated a final inflated 
average case-weighted standardized charge per case of $325,810, which 
exceeded the average case-weighted threshold amount of $98,708.
    For the fifth analysis, the applicant performed a sensitivity 
analysis to subset the cases assigned to MS-DRGs 264 (Other Circulatory 
System O.R. Procedures), 304 (Hypertension with MCC), or 305 
(Hypertension without MCC) to those reporting the following ICD-10-CM 
codes: I10 (Essential (primary) hypertension), I15.1 (Hypertension 
secondary to other renal disorders), I15.8 (Other secondary 
hypertension), or I15.9 (Secondary hypertension, unspecified) in any 
position. The applicant used the inclusion/exclusion criteria described 
in the table that follows later in this

section. Under this analysis, the applicant identified 14,415 claims 
mapping to MS-DRGs 264 (Other Circulatory System O.R. Procedures), 304 
(Hypertension with MCC), or 305 (Hypertension without MCC) and 
calculated a final inflated average case-weighted standardized charge 
per case of $272,701, which exceeded the average case-weighted 
threshold amount of $50,817.
    Because the final inflated average case-weighted standardized 
charge per case exceeded the average case-weighted threshold amount in 
all analyses, the applicant asserted that the ParadiseTM 
Ultrasound Renal Denervation System meets the cost criterion.

    We agree with the applicant that the ParadiseTM 
Ultrasound Renal Denervation System meets the cost criterion and are 
therefore proposing to approve the ParadiseTM Ultrasound 
Renal Denervation System for new technology add-on payments for FY 
2025.
    Based on preliminary information from the applicant at the time of 
this proposed rule, the applicant anticipated the total cost of the 
ParadiseTM Ultrasound Renal Denervation System to the 
hospital to be $23,000 per patient, based on single-use components 
including the operating costs of the catheter kit ($22,000), cable 
($250), and cartridge ($750). We note that the cost information for 
this technology may be updated in the final rule based on revised or 
additional information CMS receives prior to the final rule. Under 
Sec.  412.88(a)(2), we limit new technology add-on payments to the 
lesser of 65% of the average cost of the technology, or 65% of the 
costs in excess of the MS-DRG payment for the case. As a result, we are 
proposing that the maximum new technology add-on payment for a case 
involving the use of the ParadiseTM Ultrasound Renal 
Denervation System would be $14,950 for FY 2025 (that is, 65% of the 
average cost of the technology).
    We invite public comments on whether the ParadiseTM 
Ultrasound Renal Denervation System meets the cost criterion and our 
proposal to approve new technology add-on payments for the 
ParadiseTM Ultrasound Renal Denervation System for FY 2025 
for reducing blood pressure as an adjunctive treatment in hypertension 
patients in whom lifestyle modifications and antihypertensive 
medications do not adequately control blood pressure, which corresponds 
to the Breakthrough Device designation.
h. PulseSelectTM Pulsed Field Ablation (PFA) Loop Catheter
    Medtronic, Inc. submitted an application for new technology add-on 
payments for the PulseSelectTM PFA Loop Catheter for FY 
2025. According to the applicant, the PulseSelectTM PFA Loop 
Catheter is used to perform pulmonary vein isolation in cardiac 
catheter ablation to treat atrial fibrillation. Per the applicant, 
unlike existing methods that rely on thermal energy (either 
radiofrequency or cryoablation), PulseSelectTM employs non-
thermal irreversible electroporation to induce cell death in cardiac 
tissue at the target site. According to the applicant, 
PulseSelectTM technology's non-thermal approach can avoid 
risks associated with existing thermal cardiac catheter ablation 
technologies.
    Please refer to the online application posting for the 
PulseSelectTM PFA Loop Catheter, available at https://mearis.cms.gov/public/publications/ntap/NTP231017BMQKQ, for additional 
detail describing the technology and the disease treated by the 
technology.
    According to the applicant, the PulseSelectTM PFA 
System, which includes a compatible Medtronic multi-electrode cardiac 
ablation catheter (the PulseSelectTM PFA Loop Catheter), 
received Breakthrough Device designation from FDA on September 27, 
2018, for the treatment of drug refractory recurrent symptomatic atrial 
fibrillation. The Medtronic multi-electrode cardiac ablation catheter 
is also intended to be used for cardiac electrophysiological (EP) 
mapping and measuring of intracardiac electrograms, delivery of 
diagnostic pacing stimuli and verifying electrical isolation post-
treatment. According to the applicant, the PulseSelectTM PFA 
System received premarket approval on December 13, 2023 for the 
following indication that reflects a slightly narrower patient 
population compared to the Breakthrough Device designation: for cardiac 
electrophysiological mapping (stimulation and recording) and for 
treatment of drug refractory, recurrent, symptomatic paroxysmal atrial 
fibrillation or persistent atrial fibrillation (episode duration less 
than 1 year). The applicant noted that the PulseSelectTM PFA 
System consists of two primary elements: the PulseSelectTM 
PFA Loop Catheter and the PulseSelectTM PFA Generator 
system, but that as capital equipment, the PulseSelectTM PFA 
Generator system is not the subject of this new technology add-on 
payment application. According to the applicant, the technology was 
commercially available immediately after FDA approval.
    The applicant submitted a request for approval for a unique ICD-10-
PCS procedure code for the PulseSelectTM PFA System and was 
granted approval for the following procedure code effective April 1, 
2024: 02583ZF (Destruction of conduction mechanism using irreversible 
electroporation, percutaneous approach). The applicant provided a list 
of diagnosis codes that may be used to currently identify the 
indication for the PulseSelectTM PFA Loop Catheter under the 
ICD-10-CM coding system. Please refer to the online application posting 
for the complete list of ICD-10-CM codes provided by the applicant.
    With respect to the cost criterion, the applicant provided multiple 
analyses to demonstrate that it meets the cost criterion. The applicant 
stated that there is an expectation the PulseSelectTM PFA 
Loop Catheter will predominantly be used when both indicated uses are 
employed in a single patient case. Each analysis used different ICD-10-
CM codes to identify potential cases representing patients who may be 
eligible for the PulseSelectTM PFA Loop Catheter. The 
applicant explained that it used different codes to demonstrate 
different cohorts that may be eligible for the technology. Each 
analysis followed the order of operations described in the table that 
follows later in this section.
    For the first analysis, the applicant searched the FY 2022 MedPAR 
file for claims that had the ICD-10-PCS code 02583ZZ (Destruction of 
conduction mechanism, percutaneous approach) in any procedure code 
position on the claim and identified 98 MS-DRGs. The applicant limited 
the cost analysis to the top six MS-DRGs that had over 2% of cases in 
each MS-DRG (see the table that follows later in this section for a 
complete list of MS-DRGs provided by the applicant). According to the 
applicant, these six MS-DRGs represented 86% of all cardiac catheter 
ablation cases. Using the inclusion/exclusion criteria described in the 
table that follows later in this section, the applicant identified 
14,695 claims mapping to these 6 MS-DRGs. The applicant followed the 
order of operations described in the table that follows later in this 
section and calculated a final inflated average case-weighted 
standardized charge per case of $176,942, which exceeded the average 
case-weighted threshold amount of $136,813.
    For the second analysis, the applicant searched the FY 2022 MedPAR 
file for claims that had the ICD-10-PCS code 02583ZZ (Destruction of 
conduction mechanism, percutaneous approach) in any procedure code 
position on the claim, and had one of the ICD-10-CM codes for atrial 
fibrillation listed in the table that follows later in this section. 
The applicant used the inclusion/exclusion criteria described in the 
table that follows later in this section. Under this analysis, the 
applicant identified 12,088 claims mapping to the top six MS-DRGs 
(representing 82.3% of all cases) and calculated a final inflated 
average case-weighted standardized charge per case of $179,931, which 
exceeded the average case-weighted threshold amount of $136,782.
    For the third analysis, the applicant searched the FY 2022 MedPAR 
file for claims that had the ICD-10-PCS code 02583ZZ (Destruction of 
conduction mechanism, percutaneous approach) in

[[Page 36122]]

any procedure code position on the claim and had one of the ICD-10-CM 
codes for paroxysmal or persistent atrial fibrillation listed in the 
table that follows later in this section. The applicant used the 
inclusion/exclusion criteria described in the table that follows later 
in this section. Under this analysis, the applicant identified 9,446 
claims mapping to the top six MS-DRGs (representing 64.3% of all cases) 
and calculated a final inflated average case-weighted standardized 
charge per case of $180,114, which exceeded the average case-weighted 
threshold amount of $136,193.
    Because the final inflated average case-weighted standardized 
charge per case exceeded the average case-weighted threshold amount in 
all scenarios, the applicant asserted that the PulseSelectTM 
PFA Loop Catheter meets the cost criterion.

approve the PulseSelectTM

[[Page 36124]]

PFA Loop Catheter for new technology add-on payments for FY 2025.
    Based on preliminary information from the applicant at the time of 
this proposed rule, the applicant anticipated the cost of the 
PulseSelectTM PFA Loop Catheter to the hospital to be $9,750 
per patient, and for the PulseSelectTM PFA Catheter 
Interface Cable to be $800 per patient, totaling $10,550 per inpatient 
stay. We note that the cost information for this technology may be 
updated in the final rule based on revised or additional information 
CMS receives prior to the final rule. We note that the applicant stated 
that the PulseSelectTM Pulsed Field Ablation (PFA) Interface 
Cable is listed as a component of the PulseSelectTM Pulsed 
Field Ablation (PFA) Generator Reusable Accessories. However, we note 
the submitted new technology add-on payment application is for the 
PulseSelectTM PFA Loop Catheter, and that the applicant had 
specified in its application that the PulseSelectTM PFA 
Generator System is not the subject of this new technology add-on 
payment application. Therefore, we believe the total cost per inpatient 
stay should be based only on the cost of the PulseSelectTM 
PFA Loop Catheter, which is $9,750 per the applicant. Under Sec.  
412.88(a)(2), we limit new technology add-on payments to the lesser of 
65% of the average cost of the technology, or 65% of the costs in 
excess of the MS-DRG payment for the case. As a result, we are 
proposing that the maximum new technology add-on payment for a case 
involving the use of the PulseSelectTM PFA Loop Catheter 
would be $6,337.50 for FY 2025 (that is, 65% of the average cost of the 
technology).
    We invite public comments on whether the PulseSelectTM 
PFA Loop Catheter meets the cost criterion and our proposal to approve 
new technology add-on payments for the PulseSelectTM PFA 
Loop Catheter for FY 2025 for cardiac electrophysiological mapping 
(stimulation and recording) and for treatment of drug refractory, 
recurrent, symptomatic paroxysmal atrial fibrillation or persistent 
atrial fibrillation (episode duration less than 1 year).
i. Restor3d TIDALTM Fusion Cage
    Restor3d submitted an application for new technology add-on 
payments for the restor3d TIDALTM Fusion Cage for FY 2025. 
According to the applicant, the TIDALTM Fusion Cages are 
porous cages that vary in shape and size to accommodate individual 
patient anatomy. Per the applicant, the TIDALTM Fusion Cage 
is comprised of a single, continuous piece of titanium alloy fabricated 
by laser powder bed fusion, an additive manufacturing technology. 
According to the applicant, the TIDALTM Fusion Cage is an 
accessory to the intramedullary nail for TTC Fusion and has a central 
clearance hole to contain the intramedullary nail. Per the applicant, 
the restor3d TIDALTM Fusion Cage can be used to aid in 
healing for fractures, bone voids, absent bone, or surgical resections 
in conjunction with an intramedullary nail for TTC fusion. The 
applicant noted that the restor3d TIDALTM Fusion Cages also 
serve to support and contain bone graft materials that aid in 
arthrodesis.
    Please refer to the online application posting for the restor3d 
TIDALTM Fusion Cage, available at https://mearis.cms.gov/public/publications/ntap/NTP2310167MCW9, for additional detail 
describing the technology and the disease treated by the technology.
    According to the applicant, the restor3d TIDALTM Fusion 
Cage System received Breakthrough Device designation from FDA on June 
26, 2023 for the indication of tibiotalocalcaneal arthrodesis (fusion) 
to provide stabilization of the hindfoot and ankle with critical size 
bone defect, in lieu of bulk allograft in procedures such as: post-
traumatic and degenerative arthritis; post-traumatic or primary 
arthrosis involving both ankle and subtalar joints; revision after 
failed ankle arthrodesis with subtalar involvement; failed total ankle 
arthroplasty; non-union ankle arthrodesis; rheumatoid hindfoot; 
talectomy; avascular necrosis of the talus; neuroarthropathy; 
neuromuscular disease and severe deformity; osteoarthritis; Charcot 
foot; and previously infected arthrosis, second degree. The restor3d 
Fusion Cage System is intended to provide stabilization in long bones 
of skeletally mature patients, including tibia, femur and humerus, in 
the presence of critical sized bone defects in lieu of bulk allograft, 
bone transport or other treatment for segmental defects in procedures 
such as: stabilization of fractures of the diaphyseal or metaphyseal 
regions of long bones; malunions and nonunion; osteomyelitis; 
periprosthetic fractures. According to the applicant, its marketing 
authorization request for the restor3d TIDALTM Fusion Cage 
System has been accepted by FDA, and it anticipates a 510(k) decision 
from FDA for the same indication consistent with the Breakthrough 
Device designation before May 1, 2024. The applicant anticipates that 
the technology will be commercially available immediately after 510(k) 
clearance from FDA.
    According to the applicant, there are currently no ICD-10-PCS 
procedure codes to distinctly identify the restor3d TIDALTM 
Fusion Cage. The applicant submitted a request for approval for a 
unique ICD-10-PCS procedure code for the restor3d TIDALTM 
Fusion Cage beginning in FY 2025. The applicant provided a list of 
diagnosis codes that may be used to currently identify the indication 
for the restor3d TIDALTM Fusion Cage under the ICD-10-CM 
coding system. Please refer to the online application posting for the 
complete list of ICD-10-CM codes provided by the applicant.
    With respect to the cost criterion, to identify potential cases 
representing patients who may be eligible for the restor3d 
TIDALTM Fusion Cage, the applicant searched the FY 2022 
MedPAR file for claims that had one of the ICD-10-PCS codes 
corresponding to fusion procedures or claims that had one of the other 
ICD-10-PCS codes in combination with one of the selected admitting 
diagnosis ICD-10-CM codes. According to the applicant, the selected 
claims represented potential candidates for the technology, who have 
undergone tibiotalocalcaneal arthrodesis (fusion) and require 
stabilization of the hindfoot and ankle due to a critical size bone 
defect. Using the inclusion/exclusion criteria described in the 
following table, the applicant identified 14,247 claims mapping to 24 
MS-DRGs, including MS-DRG 617 (Amputation of Lower Limb for Endocrine, 
Nutritional and Metabolic Disorders with CC) and MS-DRG 853 (Infectious 
and Parasitic Diseases with O.R. Procedures with MCC), each 
representing 16% of the identified cases. The applicant followed the 
order of operations described in the following table and calculated a 
final inflated average case-weighted standardized charge per case of 
$303,575, which exceeded the average case-weighted threshold amount of 
$109,972.
    Because the final inflated average case-weighted standardized 
charge per case exceeded the average case-weighted threshold amount, 
the applicant asserted that the restor3d TIDALTM Fusion Cage 
meets the cost criterion.

BILLING CODE 4120-01-P

[[Page 36125]]

[GRAPHIC] [TIFF OMITTED] TP02MY24.135

BILLING CODE 4120-01-C
    We agree with the applicant that the restor3d TIDALTM 
Fusion Cage meets the cost criterion and are therefore proposing to 
approve the restor3d TIDALTM Fusion Cage for new technology 
add-on payments for FY 2025, subject to the technology receiving FDA 
marketing authorization as a Breakthrough Device for the indication 
corresponding to the Breakthrough Device designation by May 1, 2024.
    Based on preliminary information from the applicant at the time of 
this proposed rule, the applicant anticipated the cost of the restor3d 
TIDALTM Fusion Cage for each patient to be $27,995. In 
addition, the applicant noted the costs related to the technology for 
required supporting instruments and materials consist of one unit each 
of the Instrument Kit ($6,995), TTC Fusion Nail ($7,500), and Bone 
Graft ($1,500). The applicant estimated the total cost to the hospital 
to be $43,990 for each procedure per patient, including the related 
cost of the technology. As we have discussed in prior rulemaking, when 
determining a new technology add-on payment, we provide payment based 
on the cost of the actual technology (such as the drug or device 
itself) and not for additional costs related to the use of the device 
(86 FR 45146). Based on the information provided by the applicant, the 
cost of the Instrument Kit is included in the costs of the supporting 
instruments and materials for each procedure related to the use of the 
technology, rather than a cost of the technology itself. In addition, 
the TTC Fusion Nail and Bone Graft are not new and unique components 
for this technology, and can be purchased separately in support of 
other technologies. Furthermore, we note that the Instrument Kit is not 
included in the Breakthrough Device designation, and it therefore 
appears that only the restor3d TIDALTM Fusion Cage would be 
designated as the Breakthrough Device once market authorized and would 
be eligible for new technology add-on payments under the alternative 
pathway. Therefore, it appears any add-on payment for the restor3d 
TIDALTM Fusion Cage would include only the cost of the 
restor3d TIDALTM Fusion Cage ($27,995).
    We note that the cost information for this technology may be 
updated in the final rule based on revised or additional information 
CMS receives prior to the final rule. Under Sec.  412.88(a)(2), we 
limit new technology add-on payments to the lesser of 65% of the 
average cost of the technology, or 65% of the costs in excess of the 
MS-DRG payment for the case. As a result, we are proposing that the 
maximum new technology add-on payment for a case involving the use of 
the restor3d TIDALTM Fusion Cage would be $18,196.75 for FY 
2025 (that is, 65% of the average cost of the technology).
    We invite public comments on whether the restor3d 
TIDALTM Fusion Cage meets the cost criterion and our 
proposal to approve new technology add-on payments for the restor3d 
TIDALTM Fusion Cage for FY 2025, subject to the technology 
receiving FDA marketing authorization as a Breakthrough Device for the 
indication corresponding to the Breakthrough Device designation by May 
1, 2024.

j. Symplicity SpyralTM Multi-Electrode Renal Denervation 
Catheter
    Medtronic submitted an application for new technology add-on 
payments for the Symplicity Spyral\TM\ Multi-Electrode Renal 
Denervation Catheter for FY 2025. According to the applicant, the 
Symplicity Spyral\TM\ Multi-Electrode Renal Denervation Catheter 
provides a treatment option for patients with uncontrolled 
hypertension, when used with the Symplicity G3TM Generator, 
by delivering targeted radiofrequency energy to the renal nerves, 
safely disrupting overactive sympathetic signaling between the kidneys 
and brain, as a treatment for uncontrolled hypertension.
    Please refer to the online application posting for the Symplicity 
Spyral\TM\ Multi-Electrode Renal Denervation Catheter, available at 
https://mearis.cms.gov/public/publications/ntap/NTP2310161U617, for 
additional detail describing the technology and the condition treated 
by the technology.
    According to the applicant, the Symplicity Spyral\TM\ Multi-
Electrode Renal Denervation System received Breakthrough Device 
designation from FDA on March 27, 2020, for the reduction of blood 
pressure in patients with uncontrolled hypertension despite the use of 
anti-hypertensive medications or in patients who may have documented 
intolerance to anti-hypertensive medications. The applicant received 
premarket approval for the technology on November 17, 2023, for 
reducing blood pressure as an adjunctive treatment in patients with 
hypertension in whom lifestyle modifications and antihypertensive 
medications do not adequately control blood pressure. Because we 
consider the indication for which the applicant received premarket 
approval to be within the scope of the Breakthrough Device designation, 
and FDA considers this marketing authorization to be for the 
Breakthrough Device,\127\ it appears that the premarket approval 
indication is appropriate for consideration for new technology add-on 
payment under the alternative pathway criteria. According to the 
applicant, the technology was commercially available immediately after 
FDA approval.
---------------------------------------------------------------------------

    \127\ List of Breakthrough Devices with Marketing Authorization: 
https://www.fda.gov/medical-devices/how-study-and-market-your-device/breakthrough-devices-program.
---------------------------------------------------------------------------

    According to the applicant, there are currently no ICD-10-PCS 
procedure codes to distinctly identify the Symplicity Spyral\TM\ Multi-
Electrode Renal Denervation Catheter. The applicant submitted a request 
for approval for a unique ICD-10-PCS procedure code for the Symplicity 
Spyral\TM\ Multi-Electrode Renal Denervation Catheter beginning in FY 
2025. The applicant provided a list of diagnosis codes that may be used 
to currently identify the indication for the Symplicity Spyral\TM\ 
Multi-Electrode Renal Denervation Catheter under the ICD-10-CM coding 
system. Please refer to the online application posting for the complete 
list of ICD-10-CM codes provided by the applicant.
    With respect to the cost criterion, the applicant provided two 
analyses and two sensitivity analyses to demonstrate that it meets the 
cost criterion. Each analysis used a common set of ICD-10-CM codes but 
different criteria for the inclusion/exclusion of MS-DRGs and outlier 
cases to identify potential cases representing patients who may be 
eligible for the Symplicity Spyral\TM\ Multi-Electrode Renal 
Denervation Catheter. The applicant explained that it used different 
codes to demonstrate different cohorts that may be eligible for the 
technology. Each analysis followed the order of operations described in 
the table that follows later in this section.
    For the first scenario (Cost Analysis #1), the applicant searched 
the FY 2022 MedPAR file for cases where essential (primary) 
hypertension was the reason for the admission, using at least one of 
the ICD-10-CM diagnosis codes in the table that follows later in this 
section. The applicant used the inclusion/exclusion criteria described 
in the table that follows later in this section. Under this analysis, 
the applicant identified 490,387 claims mapping to 99 MS-DRGs, 
including MS-DRG 291 (Heart Failure and Shock With MCC) representing 
67% of identified cases. The applicant calculated a final inflated 
average case-weighted standardized charge per case of $136,450, which 
exceeded the average case-weighted threshold amount of $62,312.
    The second scenario (Cost Analysis #1 with Outliers) was a 
sensitivity analysis that mirrored the first scenario, except that 
cases with outlier payments were included. The applicant used the 
inclusion/exclusion criteria described in the table that follows later 
in this section. Under this analysis, the applicant identified 501,760 
claims mapping to 101 MS-DRGs, including MS-DRG 291 (Heart Failure and 
Shock With MCC) representing 66.7% of identified cases. The applicant 
calculated a final inflated average case-weighted standardized charge 
per case of $145,001, which exceeded the average case-weighted 
threshold amount of $63,789.
    For the third scenario (Cost Analysis #2), the applicant searched 
the FY 2022 MedPAR file for claims reporting any of the ICD-10-CM 
diagnosis codes listed in the table that follows later in this section 
but limited the case selection to MS-DRGs where the principal diagnosis 
was essential hypertension, and no procedures were performed. Per the 
applicant, this list represents a subset of cases that were most likely 
to benefit from the new procedural treatment option for primary 
hypertension. The applicant used the inclusion/exclusion criteria 
described in the table that follows later in this section. Under this 
analysis, the applicant identified 390,384 claims mapping to 8 MS-DRGs, 
including MS-DRG 291 (Heart Failure and Shock With MCC) representing 
84.4% of identified cases. The applicant calculated a final inflated 
average case-weighted standardized charge per case of $124,525, which 
exceeded the average case-weighted threshold amount of $52,861.
    The fourth scenario (Cost Analysis #2 with Outliers) mirrored the 
third scenario, except that cases with outlier payments were included. 
The applicant used the inclusion/exclusion criteria described in the 
table that follows later in this section. Under this analysis, the 
applicant identified 395,634 claims mapping to 8 MS-DRGs, including MS-
DRG 291 (Heart Failure and Shock With MCC) representing 84.5% of 
identified cases. The applicant calculated a final inflated average 
case-weighted standardized charge per case of $128,356, which exceeded 
the average case-weighted threshold amount of $52,873.
    Because the final inflated average case-weighted standardized 
charge per case exceeded the average case-weighted threshold amount in 
all scenarios, the applicant asserted that the Symplicity Spyral\TM\ 
Multi-Electrode Renal Denervation Catheter meets the cost criterion.

BILLING CODE 4120-01-C
    We agree with the applicant that the Symplicity Spyral\TM\ Multi-
Electrode Renal Denervation Catheter meets the cost criterion and are 
therefore proposing to approve the Symplicity Spyral\TM\ Multi-
Electrode Renal Denervation Catheter for new technology add-on payments 
for FY 2025.
    An estimate for the cost of the Symplicity Spyral\TM\ Multi-
Electrode Renal Denervation Catheter is not available for publication 
at the time of this proposed rule. We expect the applicant to release 
cost information prior to the final rule, and we will provide an update 
regarding the new technology add-on payment amount for the technology, 
if approved, in the final rule. The applicant stated that there would 
be two components for the cost of the technology, including operating 
costs for the Symplicity Spyral\TM\ Multi-Electrode Renal Denervation 
Catheter and capital costs for the Symplicity G3TM 
Generator. Because section 1886(d)(5)(K)(i) of the Act requires that 
the Secretary establish a mechanism to recognize the costs of new 
medical services or technologies under the payment system established 
under that subsection, which establishes the system for payment of the 
operating costs of inpatient hospital services, we do not include 
capital costs in the add-on payments for a new medical service or 
technology or make new technology add-on payments under the IPPS for 
capital-related costs (86 FR 45145). Based on the information from the 
applicant, it appears that the Symplicity G3TM Generator is 
a capital cost. Therefore, it appears that this component is not 
eligible for new technology add-on payment because, as discussed in 
prior rulemaking and as noted, we only make new technology add-on 
payments for operating costs (72 FR 47307 through 47308). Any new 
technology add-on payment for the Symplicity Spyral\TM\ Multi-Electrode 
Renal Denervation Catheter would be subject to our policy under Sec.  
412.88(a)(2) where we limit new technology add-on payment to the lesser 
of 65% of the average cost of the technology, or 65% of the costs in 
excess of the MS-DRG payment for the case.
    We invite public comments on whether the Symplicity Spyral\TM\ 
Multi-Electrode Renal Denervation Catheter meets the cost criterion and 
our proposal to approve new technology add-on payments for the 
Symplicity Spyral\TM\ Multi-Electrode Renal Denervation Catheter for FY 
2025 for reducing blood pressure as an adjunctive treatment in patients 
with hypertension in whom lifestyle modifications and antihypertensive 
medications do not adequately control blood pressure, which corresponds 
to the Breakthrough Device designation
k. Transdermal Glomerular Filtration Rate (GFR) Measurement System 
Utilizing Lumitrace
    MediBeacon, Inc. submitted an application for new technology add-on 
payments for the Transdermal GFR Measurement System utilizing Lumitrace 
for FY 2025. According to the applicant, the Transdermal GFR 
Measurement System utilizing Lumitrace is a three-component system: (1) 
an optical skin sensor, (2) a monitor, and (3) Lumitrace 
(relmapirazin), which is a proprietary fluorescent tracer agent

[[Page 36129]]

that glows in the presence of light and is removed from the blood 
exclusively by the GFR mechanism of the kidney. The technology is 
intended to measure GFR in patients with impaired or normal renal 
function during clinical conditions where the real time measurement of 
GFR (versus estimated measures) is clinically useful in the 
understanding of kidney function. We note that MediBeacon, Inc. 
submitted an application for new technology add-on payments for the 
Transdermal GFR Measurement System utilizing Lumitrace for FY 2024, as 
summarized in the FY 2024 IPPS/LTCH PPS proposed rule (88 FR 26954 
through 26955), that it withdrew prior to the issuance of the FY 2024 
IPPS/LTCH PPS final rule (88 FR 58919).
    Please refer to the online application posting for the Transdermal 
GFR Measurement System utilizing Lumitrace, available at https://mearis.cms.gov/public/publications/ntap/NTP23101671HAA, for additional 
detail describing the technology.
    According to the applicant, the Transdermal GFR Measurement System 
utilizing Lumitrace received Breakthrough Device designation from FDA 
on October 16, 2018, for measuring GFR in patients with impaired or 
normal renal function. According to the applicant, its marketing 
authorization request for the Transdermal GFR Measurement System 
utilizing Lumitrace has been filed by FDA, and it anticipates a 
premarket approval decision from FDA for the same indication consistent 
with the Breakthrough Device designation before May 1, 2024. According 
to the applicant, the Transdermal GFR Measurement System will not be 
immediately available for sale because it is waiting for premarket 
approval from FDA before producing large volumes of the agent, sensor, 
and monitor, and anticipates a limited launch prior to widespread 
availability.
    The applicant stated that effective October 1, 2019, the following 
ICD-10-PCS code may be used to uniquely describe procedures involving 
the use of the Transdermal GFR Measurement System utilizing Lumitrace: 
XT25XE5 (Monitoring of kidney using fluorescent pyrazine, external 
approach, new technology group 5).
    With respect to the cost criterion, to identify potential cases 
representing patients who may be eligible for the Transdermal GFR 
Measurement System utilizing Lumitrace, the applicant searched the FY 
2022 MedPAR file for claims that had one of the ICD-10-CM codes or the 
ICD-10-PCS codes representing patients who are likely to require and/or 
benefit from real-time kidney function monitoring during the inpatient 
hospital stay. Using the inclusion/exclusion criteria described in the 
following table, the applicant identified 470,171 claims mapping to 697 
MS-DRGs, including MS-DRG 871 (Septicemia or Severe Sepsis without MV 
>96 Hours with MCC) representing 15% of the identified cases. The 
applicant followed the order of operations described in the following 
table and calculated a final inflated average case-weighted 
standardized charge per case of $231,117, which exceeded the average 
case-weighted threshold amount of $134,438.
    Because the final inflated average case-weighted standardized 
charge per case exceeded the average case-weighted threshold amount, 
the applicant asserted that the Transdermal GFR Measurement System 
utilizing Lumitrace meets the cost criterion.

    We agree with the applicant that the Transdermal GFR Measurement 
System utilizing Lumitrace meets the cost criterion and are therefore 
proposing to approve the Transdermal GFR Measurement System utilizing 
Lumitrace for new technology add-on payments for FY 2025, subject to 
the technology receiving FDA marketing authorization as a Breakthrough 
Device for the indication corresponding to the Breakthrough Device 
designation by May 1, 2024.
    The applicant has not provided an estimate for the cost of the 
Transdermal GFR Measurement System utilizing Lumitrace at the time of 
this proposed rule. The applicant stated that there would be three 
components for the cost of the technology: the operating cost of the 
Transdermal GFR Measurement System Sensor, the operating cost of 
Lumitrace (relmapirazin) that glows in the presence of light and is 
removed from the blood exclusively by the GFR mechanism of the kidney, 
and the capital cost of the Transdermal GFR Measurement System Monitor 
that displays fluorescence collected by the Transdermal GFR Measurement 
System Sensor to provide an indication of changes in transdermal GFR 
over time. Because section 1886(d)(5)(K)(i) of the Act requires that 
the Secretary establish a mechanism to recognize the costs of new 
medical services or technologies under the payment system established 
under that subsection, which establishes the system for payment of the 
operating costs of inpatient hospital services, we do not include 
capital costs in the add-on payments for a new medical service or 
technology or make new technology add-on payments under the IPPS for 
capital-related costs (86 FR 45145). As noted, the applicant stated 
that the cost of the Transdermal GFR Measurement System Monitor is a 
capital cost. Therefore, it appears that this component is not eligible 
for new technology add-on payment because, as discussed in prior 
rulemaking and as noted, we only make new technology add-on payments 
for operating costs (72 FR 47307 through 47308). We expect the 
applicant to submit cost information prior to the final rule, and we 
will provide an update regarding the new technology add-on payment 
amount for the technology, if approved, in the final rule. Any new 
technology add-on payment for the Transdermal GFR Measurement System 
utilizing Lumitrace would be subject to our policy under Sec.  
412.88(a)(2) where we limit new technology add-on payments to the 
lesser of 65% of the average cost of the technology, or 65% of the 
costs in excess of the MS-DRG payment for the case.
    We invite public comments on whether the Transdermal GFR 
Measurement System utilizing Lumitrace meets the cost criterion and our 
proposal to approve new technology add-on payments for the Transdermal 
GFR Measurement System utilizing Lumitrace for FY 2025, subject to the 
technology receiving FDA marketing authorization as a Breakthrough 
Device for the indication corresponding to the Breakthrough Device 
designation by May 1, 2024.
l. TriClipTM G4
    Abbott submitted an application for new technology add-on payments 
for TriClip\TM\ G4 for FY 2025. According to the applicant, TriClip\TM\ 
G4 is intended for reconstruction of the insufficient tricuspid valve 
through tissue approximation via a transcatheter approach. The 
TriClip\TM\ G4 System consists of the TriClip\TM\ G4 Implant,

[[Page 36131]]

Clip Delivery System and Steerable Guide. The applicant explained that 
the TriClip\TM\ G4 Implant is a percutaneously delivered mechanical 
implant that helps close the tricuspid valve leaflets resulting in 
fixed tricuspid leaflet approximation throughout the cardiac cycle. 
According to the applicant, TriClip\TM\ G4 is intended for the 
treatment of patients with symptomatic, severe tricuspid valve 
regurgitation, whose symptoms and tricuspid regurgitation (TR) severity 
persist despite being treated optimally with medical therapy.
    Please refer to the online application posting for TriClip\TM\ G4, 
available at https://mearis.cms.gov/public/publications/ntap/NTP231016N52MH, for additional detail describing the technology and the 
disease treated by the technology.
    According to the applicant, the TriClip\TM\ G4 System received 
Breakthrough Device designation from FDA on November 19, 2020, for the 
treatment of patients with symptomatic, severe tricuspid valve 
regurgitation, whose symptoms and TR severity persist despite being 
treated optimally with medical therapy. According to the applicant, its 
marketing authorization request has been filed by FDA, and it 
anticipates a premarket approval (PMA) decision from FDA for the same 
indication consistent with the Breakthrough Device designation before 
May 1, 2024. According to the applicant, the technology is expected to 
be commercially available immediately after FDA approval.
    According to the applicant, the following ICD-10-PCS code may be 
used to describe procedures involving the use of TriClip\TM\ G4: 
02UJ3JZ (Supplement tricuspid valve with synthetic substitute, 
percutaneous approach). The applicant noted that there are no FDA-
approved technologies using this procedure code. The applicant stated 
that ICD-10-CM diagnosis codes I07.1 (Rheumatic tricuspid 
insufficiency) and I36.1 (Nonrheumatic tricuspid (valve) insufficiency) 
may be used to currently identify the indication for TriClip\TM\ G4 
under the ICD-10-CM coding system.
    With respect to the cost criterion, to identify potential cases 
representing patients who may be eligible for TriClip\TM\ G4, the 
applicant searched the 2022 Medicare Inpatient Hospital Standard 
Analytical File (100%) for claims that had one of the following ICD-10-
CM codes, I07.1 (Rheumatic tricuspid insufficiency) or I36.1 
(Nonrheumatic tricuspid (valve) insufficiency) in the primary position, 
in combination with ICD-10-PCS code 02UJ3JZ (Supplement tricuspid valve 
with synthetic substitute, percutaneous approach). Using the inclusion/
exclusion criteria described in the following table, the applicant 
identified 235 claims mapping to two MS-DRGs, MS-DRG 266 (Endovascular 
Cardiac Valve Replacement and Supplement Procedures, with MCC), and 267 
(Endovascular Cardiac Valve Replacement and Supplement Procedures, 
without MCC). The applicant followed the order of operations described 
in the following table and calculated a final inflated average case-
weighted standardized charge per case of $313,389 which exceeded the 
average case-weighted threshold amount of $192,861.
    Because the final inflated average case-weighted standardized 
charge per case exceeded the average case-weighted threshold amount, 
the applicant asserted that TriClip\TM\ G4 meets the cost criterion.

[[Page 36132]]


    We agree with the applicant that TriClip\TM\ G4 meets the cost 
criterion and are therefore proposing to approve TriClip\TM\ G4 for new 
technology add-on payments for FY 2025, subject to the technology 
receiving FDA marketing authorization as a Breakthrough Device for the 
indication corresponding to the Breakthrough Device designation by May 
1, 2024.
    Based on preliminary information from the applicant at the time of 
this proposed rule, the applicant anticipated the total cost of 
TriClip\TM\ G4 to the hospital to be $40,000 per procedure. According 
to the applicant, the TriClip\TM\ System is composed of multiple 
components: the TriClip\TM\ G4 Implant, Clip Delivery System, and 
Steerable Guide Catheter. The applicant stated that all the components 
typically required for a single procedure are sold together for a 
single operating cost (for example, it is the same cost per procedure 
whether the patient requires one or two implants). We note that the 
cost information for this technology may be updated in the final rule 
based on revised or additional information CMS receives prior to the 
final rule. Under Sec.  412.88(a)(2), we limit new technology add-on 
payments to the lesser of 65% of the average cost of the technology, or 
65% of the costs in excess of the MS-DRG payment for the case. As a 
result, we are proposing that the maximum new technology add-on payment 
for a case involving the use of TriClip\TM\ G4 would be $26,000 for FY 
2025 (that is, 65% of the average cost of the technology).
    We invite public comments on whether TriClip\TM\ G4 meets the cost 
criterion and our proposal to approve new technology add-on payments 
for TriClip\TM\ G4 for FY 2025, subject to the technology receiving FDA 
marketing authorization as a Breakthrough Device for the indication 
corresponding to the Breakthrough Device designation by May 1, 2024.
m. VADER[supreg] Pedicle System
    Icotec Medical, Inc. submitted an application for new technology 
add-on payments for the VADER[supreg] Pedicle System for FY 2025. 
According to the applicant, the VADER[supreg] Pedicle System is a 
pedicle screw system for standard posterior fixation of the spinal 
column used to provide stabilization of infected spinal segments after 
debridement of infectious tissues. According to the applicant, the 
VADER[supreg] Pedicle System is made from high strength carbon fiber 
reinforced polyether ether ketone, which provides low artifact imaging 
to allow for post-operative surveillance of the healing of the infected 
spinal segment.
    Please refer to the online application posting for the 
VADER[supreg] Pedicle System, available at https://mearis.cms.gov/public/publications/ntap/NTP231016CMGH3, for additional detail 
describing the technology and the condition treated by the technology.
    According to the applicant, the VADER[supreg] Pedicle System 
received Breakthrough Device designation from FDA on July 31, 2023 for 
stabilizing the thoracic and/or lumbar spinal column as an adjunct to 
fusion in patients diagnosed with an active spinal infection (for 
example, spondylodiscitis, osteomyelitis) who are at risk of spinal 
instability, progressive spinal deformity, or neurologic compromise, 
following surgical debridement. The applicant stated that the 
technology received 510(k) clearance from FDA on February 26, 2024, for 
the following indication, which is the subject of the new technology 
add-on payment application, and is consistent with the Breakthrough 
Device designation: to stabilize the thoracic and/or lumbar spinal 
column in patients who are or will be receiving concurrent medical 
treatment for an active spinal infection (for example, 
spondylodiscitis, osteomyelitis) that, without stabilization, could 
lead to deterioration of bony structures and misalignment with 
neurological compromise. We note that the VADER[supreg] Pedicle System 
has received FDA 510(k) clearance for multiple indications since 
2019.\130\ We also note that, under the eligibility criteria for 
approval under the alternative pathway for certain transformative new 
devices, only the use of the VADER[supreg] Pedicle System to stabilize 
the thoracic and/or lumbar spine as an adjunct to fusion in patients 
with spinal infection, and the FDA Breakthrough Device designation it 
received for that use, are relevant for purposes of the new technology 
add-on payment application for FY 2025. According to the applicant, the 
technology was commercially available immediately after 510(k) 
clearance from FDA.

---------------------------------------------------------------------------

    According to the applicant, there are currently no ICD-10-PCS 
procedure codes to distinctly identify the VADER[supreg] Pedicle 
System. The applicant submitted a request for approval for a unique 
ICD-10-PCS procedure code for the VADER[supreg] Pedicle System 
beginning in FY 2025. The applicant provided a list of diagnosis codes 
that may be used to currently identify the indication for the 
VADER[supreg] Pedicle System under the ICD-10-CM coding system, 
describing spinal infections including osteomyelitis, discitis, and 
spondylopathies of various vertebral spine body parts including the 
cervical, thoracic, and lumbar regions. Please refer to the online 
application posting for the complete list of ICD-10-CM codes provided 
by the applicant. As previously noted, only use of the technology for 
the indications corresponding to the Breakthrough Device designation 
would be relevant for new technology add-on payment purposes. We 
believe the relevant ICD-10-CM codes to identify the Breakthrough 
Device-designated indication would be the codes included in category 
M46 (Other inflammatory spondylopathies) under the ICD-10-CM 
classification in subcategories: M46.2- (Osteomyelitis of vertebra), 
M46.3- (Infection of intervertebral disc (pyogenic)), M46.4- (Discitis, 
unspecified), M46.5- (Other infective spondylopathies), M46.8- (Other 
specified inflammatory spondylopathies), and M46.9- (Unspecified 
inflammatory spondylopathy). We are inviting public comment on the use 
of these ICD-10-CM diagnosis codes to identify the Breakthrough Device-
designated indication for purposes of the new technology add-on 
payment, if approved.
    With respect to the cost criterion, to identify potential cases 
representing patients who may be eligible for the VADER[supreg] Pedicle 
System, the applicant searched the FY 2022 MedPAR file for claims 
reporting a combination of ICD-10-CM/PCS codes as listed in the online 
posting for the VADER[supreg] Pedicle System. The applicant believes 
these cases represent patients who have undergone fusion procedures and 
have been diagnosed with an active spinal infection (such as 
spondylodiscitis or osteomyelitis), and these patients are at risk of 
spinal instability, progressive spinal deformity, or neurologic 
compromise following surgical debridement, making them suitable 
candidates for the use of the technology. Using the inclusion/exclusion 
criteria described in the following table, the applicant identified 
2,116 claims mapping to 22 MS-DRGs, with none exceeding more than 15% 
of the total identified cases. The applicant followed the order of 
operations described in the following table and calculated a final 
inflated average case-weighted standardized charge per case of 
$473,636, which exceeded the average case-weighted threshold amount of

[[Page 36133]]

$197,922. Because the final inflated average case-weighted standardized 
charge per case exceeded the average case-weighted threshold amount, 
the applicant asserted that the VADER[supreg] Pedicle System meets the 
cost criterion.

BILLING CODE 4120-01-P
[GRAPHIC] [TIFF OMITTED] TP02MY24.140

BILLING CODE 4120-01-C
    We agree with the applicant that the VADER[supreg] Pedicle System 
meets the cost criterion and are therefore proposing to approve the 
VADER[supreg] Pedicle System for new technology add-on payments for FY 
2025.
    Based on preliminary information from the applicant at the time of 
this proposed rule, the applicant anticipated the total cost of the 
VADER[supreg] Pedicle System to the hospital to be $43,450 per patient. 
According to the applicant, the unit prices are $6,500 for a pedicle 
screw, $4,600 for a rod, and $350 for a set screw. The applicant stated 
that an average of five pedicle screws, two rods, and five set screws 
would be used for a spinal fusion procedure. The applicant calculated 
the total cost of the technology by multiplying the unit price of each 
component by the average number of that component used in the 
procedure. We note that the cost information for this technology may be 
updated in the final rule based on revised or additional information 
CMS receives prior to the final rule. Under Sec.  412.88(a)(2), we 
limit new technology add-on payments to the lesser of 65% of the 
average cost of the technology, or 65% of the costs in excess of the 
MS-DRG payment for the case. As a result, we are proposing that the 
maximum new technology add-on payment for a case involving the use of 
the VADER[supreg] Pedicle System would be $28,242.50 for FY 2025 (that 
is, 65% of the average cost of the technology).
    We invite public comments on whether the VADER[supreg] Pedicle 
System meets the cost criterion and our proposal to approve new 
technology add-on payments for the VADER[supreg] Pedicle System for FY 
2025, when used

[[Page 36134]]

to stabilize the thoracic and/or lumbar spinal column in patients who 
are or will be receiving concurrent medical treatment for an active 
spinal infection (for example, spondylodiscitis, osteomyelitis) that, 
without stabilization, could lead to deterioration of bony structures 
and misalignment with neurological compromise.
n. ZEVTERATM (Ceftobiprole Medocaril)
    Basilea Pharmaceutica International Ltd, Allschwil submitted an 
application for new technology add-on payments for ZEVTERA\TM\ 
(ceftobiprole medocaril) for FY 2025. According to the applicant, 
ZEVTERA\TM\ is an advanced intravenous cephalosporin antibiotic 
designed to combat infections caused by antibiotic resistant pathogens. 
The applicant stated that ZEVTERATM targets a wide range of 
Gram-positive and Gram-negative bacteria, including methicillin-
resistant Staphylococcus aureus (MRSA), Streptococcus pneumoniae, 
including penicillin-non-susceptible pneumococci (PNSP) and 
Enterococcus faecalis, as well as non-Extended Spectrum Beta-Lactamase 
(non-ESBL) producing Enterobacterales. The applicant noted that 
ZEVTERA\TM\'s bactericidal activity is achieved by binding to essential 
penicillin-binding proteins, disrupting the synthesis of the bacterial 
cell wall's peptidoglycan layer and leading to bacterial cell death, 
which differentiates it from other beta-lactams by effectively 
addressing MRSA. Per the applicant, ZEVTERA\TM\ is stable against 
certain beta-lactamases in both gram-positive and gram-negative 
bacteria. The applicant stated that Phase 3 studies submitted to the 
FDA demonstrate its non-inferiority compared to standard treatments in 
various infections, including Staphylococcus aureus bacteremia (SAB), 
acute bacterial skin and skin structure infections (ABSSSI), and 
community-acquired bacterial pneumonia (CABP).
    Please refer to the online application posting for ZEVTERA\TM\, 
available at https://mearis.cms.gov/public/publications/ntap/NTP2310161DBB8, for additional detail describing the technology and the 
disease treated by the technology.
    According to the applicant, ZEVTERA\TM\ received QIDP designations 
for CABP on July 20, 2015, for ABSSI on August 7, 2015, and for SAB on 
December 8, 2017. According to the applicant, its marketing 
authorization request for ZEVTERATM has been filed by FDA, 
and it anticipates an NDA decision from FDA for the same indications 
consistent with the QIDP designations by July 1, 2024. According to the 
applicant, ZEVTERA\TM\ will be commercially available immediately after 
FDA approval. We note that, as an application submitted under the 
alternative pathway for certain antimicrobial products at Sec.  
412.87(d), ZEVTERA\TM\ is eligible for conditional approval for new 
technology add-on payments if it does not receive FDA marketing 
authorization by July 1, 2024, provided that the technology receives 
FDA marketing authorization before July 1 of the fiscal year for which 
the applicant applied for new technology add-on payments (that is, July 
1, 2025), as provided in Sec.  412.87(f)(3). According to the 
applicant, for CABP and ABSSSI, ZEVTERA\TM\ is dosed at 500mg and 
administered three times daily (Q8h) as a 2-hour intravenous infusion 
for 5-14 days. For SAB, it is administered four times daily (Q6h) for 
the first 8 days, followed by Q8h daily infusion for the subsequent 
days, up to a total of 42 days.
    According to the applicant, there are currently no ICD-10-PCS 
procedure codes to distinctly identify ZEVTERA\TM\. We note that the 
applicant submitted a request for approval for a unique ICD-10-PCS 
procedure code for ZEVTERA\TM\ beginning in FY 2025. The applicant 
provided a list of diagnosis codes that may be used to currently 
identify the indication for ZEVTERA\TM\ under the ICD-10-CM coding 
system, describing SAB, ABSSSI, and CABP. Please refer to the online 
application posting for the complete list of ICD-10-CM (and PCS) codes 
provided by the applicant. We believe the relevant combination of ICD-
10-CM codes to identify the indication of SAB would be: R78.81 
(Bacteremia) in combination with B95.61 (Methicillin susceptible 
Staphylococcus aureus infection as the cause of diseases classified 
elsewhere) or B95.62 (Methicillin resistant Staphylococcus aureus 
infection as the cause of diseases classified elsewhere). We are 
inviting public comments on the use of these ICD-10-CM diagnosis codes 
to identify the indication of SAB for purposes of the new technology 
add-on payment, if approved.
    With respect to the cost criterion, the applicant provided multiple 
analyses to demonstrate that it meets the cost criterion. For each 
analysis, the applicant searched the FY 2022 MedPAR file using 
different sets of ICD-10-CM codes in the first five diagnosis positions 
to identify potential cases representing different cohorts of patients 
who may be eligible for ZEVTERA\TM\. The applicant performed the same 
analysis on ABSSSI, CABP, and SAB cases individually and for all 
indications combined.
    For the first analysis, the applicant searched for claims with a 
diagnosis code for ABSSSI using the ICD-10-CM codes listed in the 
online posting for ZEVTERA\TM\. The applicant used the inclusion/
exclusion criteria described in the table that follows later in this 
section. Under this analysis, the applicant identified 261,397 claims 
mapping to 663 MS-DRGs and calculated a final inflated average case-
weighted standardized charge per case of $114,279, which exceeded the 
average case-weighted threshold amount of $63,767.
    For the second analysis, the applicant searched for claims with a 
diagnosis code for CABP using the ICD-10-CM codes listed in the online 
posting for ZEVTERA\TM\. The applicant used the inclusion/exclusion 
criteria described in the table that follows later in this section. 
Under this analysis, the applicant identified 635,628 claims mapping to 
611 MS-DRGs and calculated a final inflated average case-weighted 
standardized charge per case of $143,456, which exceeded the average 
case-weighted threshold amount of $78,778.
    For the third analysis, the applicant searched for claims with a 
diagnosis code for SAB using the ICD-10-CM codes listed in the online 
posting for ZEVTERA\TM\. The applicant used the inclusion/exclusion 
criteria described in the table that follows later in this section. 
Under this analysis, the applicant identified 105,068 claims mapping to 
626 MS-DRGs and calculated a final inflated average case-weighted 
standardized charge per case of $165,809, which exceeded the average 
case-weighted threshold amount of $82,238.
    For the fourth analysis, the applicant searched for claims with 
diagnosis codes for ABSSSI, CABP, or SAB in the first five positions on 
a claim, using the ICD-10-CM codes listed in the online posting for 
ZEVTERA\TM\. The applicant used the inclusion/exclusion criteria 
described in the table that follows later in this section. Under this 
analysis, the applicant identified 958,104 claims mapping to 680 MS-
DRGs and calculated a final inflated average case-weighted standardized 
charge per case of $137,861, which exceeded the average case-weighted 
threshold amount of $75,097.
    Because the final inflated average case-weighted standardized 
charge per case exceeded the average case-weighted threshold amount in 
all scenarios, the applicant asserted that ZEVTERA\TM\ meets the cost 
criterion.

BILLING CODE 4120-01-P

[[Page 36135]]

[GRAPHIC] [TIFF OMITTED] TP02MY24.141

BILLING CODE 4120-01-C
    We agree with the applicant that ZEVTERA\TM\ meets the cost 
criterion and are therefore proposing to approve ZEVTERA\TM\ for new 
technology add-on payments for FY 2025, subject to the technology 
receiving FDA marketing authorization for the indication corresponding 
to the QIDP designation by July 1, 2024. As an application submitted 
under the alternative pathway for certain antimicrobial products at 
Sec.  412.87(d), ZEVTERA\TM\ is eligible for conditional approval for 
new technology add-on payments if it does not receive FDA marketing 
authorization by July 1, 2024, provided that the technology receives 
FDA marketing authorization before July 1 of the fiscal year for which 
the applicant applied for new technology add-on payments (that is, July 
1, 2025), as provided in Sec.  412.87(f)(3). If ZEVTERA\TM\ receives 
FDA marketing authorization before July 1, 2025, the new technology 
add-on payment for cases involving the use of this technology would be 
made effective for discharges beginning in the first quarter after FDA 
marketing authorization is granted. If FDA marketing authorization is 
received on or after July 1, 2025, no new technology add-on payments 
would be made for cases involving the use of ZEVTERA\TM\ for FY 2025.
    Based on preliminary information from the applicant at the time of 
this proposed rule, the pricing for this treatment is set at $125 per 
vial, and the recommended dosage varies depending on the condition 
being treated. The applicant stated that for ABSSSI and CABP, the 
suggested daily dose is 3 vials per day for a duration of 5-14 days, 
resulting in an estimated average cost of $3,750 for a 10-day therapy. 
The applicant noted that for SAB, the recommended dose is every 6 hours 
for the first 8 days, followed by every 8 hours for up to 42 days. The 
applicant made the assumption that patients would be inpatient for 28 
days and then continue the therapy as an outpatient for up to 42 days, 
which resulted in an average inpatient cost of $11,500. We note that 
the cost information for this technology may be updated in the final 
rule based on revised or additional information CMS receives prior to 
the final rule. Under Sec.  412.88(a)(2), we limit new technology add-
on payments for technologies designated as QIDPs to the lesser of 75% 
of the average cost of the technology, or 75% of the costs in excess of 
the MS-DRG payment for the case. As a result, we are proposing that the 
maximum new technology add-on payment for a case involving the use of 
ZEVTERA\TM\ for FY 2025 would be $8,625.00 for the indication of SAB 
and $2,812.50 for the indications of ABSSSI and CABP (that is, 75% of 
the average cost of the technology).
    We invite public comments on whether ZEVTERA\TM\ meets the cost 
criterion and our proposal to approve new technology add-on payments 
for ZEVTERA\TM\ for FY 2025 for SAB, ABSSSI, and CABP, subject to the 
technology receiving FDA marketing

[[Page 36136]]

authorization consistent with its QIDP designations by July 1, 2024.
7. Proposed Change to the Method for Determining Whether a Technology 
Would Be Within Its 2- to 3-Year Newness Period When Considering 
Eligibility for New Technology Add-On Payments
    As discussed previously in this rule, section 1886(d)(5)(K)(i) of 
the Act requires the Secretary to establish (after notice and 
opportunity for public comment) a mechanism to recognize the costs of 
new medical services and technologies under the IPPS. Section 
1886(d)(5)(K)(vi) of the Act specifies that a medical service or 
technology will be considered new if it meets criteria established by 
the Secretary after notice and opportunity for public comment. The 
regulations at 42 CFR 412.87 implement these provisions. As further 
discussed in FY 2005 IPPS final rule (69 FR 49002), the intent of 
section 1886(d)(5)(K) of the Act and regulations under Sec.  
412.87(b)(2) is to pay for new medical services and technologies for 
the first 2 to 3 years that a product comes on the market, during the 
period when the costs of the new technology are not yet fully reflected 
in the DRG weights. Generally, we use the FDA marketing authorization 
date as the indicator of the time when a technology begins to become 
available on the market and data reflecting the costs of the technology 
begin to become available for recalibration of the DRG weights. In 
specific circumstances, we have recognized a date later than the FDA 
marketing authorization date as the appropriate starting point for the 
2- to 3-year newness period. For example, we have recognized a later 
date where an applicant could prove a delay in actual availability of a 
product after FDA approval or clearance. The costs of the new medical 
service or technology, once paid for by Medicare for this 2- to 3-year 
period, are accounted for in the MedPAR data that are used to 
recalibrate the DRG weights on an annual basis. Therefore, we stated it 
is appropriate to limit the add-on payment window for technologies that 
have passed this 2- to 3-year timeframe.
    As discussed previously in this rule, our policy is that a medical 
service or technology may continue to be considered ``new'' for 
purposes of new technology add-on payments within 2 or 3 years after 
the point at which data begin to become available reflecting the 
inpatient hospital code assigned to the new service or technology. Our 
practice has been to begin and end new technology add-on payments on 
the basis of a fiscal year, and we have generally followed a guideline 
that uses a 6-month window before and after the start of the fiscal 
year to determine whether to extend the new technology add-on payment 
for an additional fiscal year. In general, we extend new technology 
add-on payments for an additional year only if the three-year 
anniversary date of the product's entry onto the U.S. market occurs in 
the latter half of the fiscal year, that is, after April 1 (70 FR 
47362).
    We have not implemented a policy to stop new technology add-on 
payment in the middle of the fiscal year (for example, during the month 
that a technology reaches its three-year anniversary date of entry onto 
the U.S. market) because, as we discussed in the FY 2005 IPPS final 
rule, we believe that predictability is an important aspect of the 
prospective payment system methodology. Accordingly, we believe that it 
is appropriate to apply a consistent payment methodology for new 
technologies throughout the fiscal year (69 FR 49016).
    As previously discussed, in the FY 2024 IPPS/LTCH PPS final rule 
(88 FR 58948 through 58958), we finalized that beginning with the new 
technology add-on payment applications for FY 2025, for technologies 
that are not already FDA market authorized for the indication that is 
the subject of the new technology add-on payment application, 
applicants must have a complete and active FDA marketing authorization 
request at the time of new technology add-on payment application 
submission and must provide documentation of FDA acceptance or filing 
to CMS at the time of application submission, consistent with the type 
of FDA marketing authorization application the applicant has submitted 
to FDA. We also finalized that, beginning with FY 2025 applications, in 
order to be eligible for consideration for new technology add-on 
payment for the upcoming fiscal year, an applicant for new technology 
add-on payments must have received FDA approval or clearance by May 1 
(rather than July 1) of the year prior to the beginning of the fiscal 
year for which the application is being considered (except for an 
application that is submitted under the alternative pathway for certain 
antimicrobial products).
    As we summarized in the FY 2024 IPPS/LTCH PPS final rule, 
commenters raised concerns that this policy would adversely impact 
their ability to receive maximum flexibility with respect to when to 
apply to FDA and when they apply for new technology add-on payment (88 
FR 58953). Many commenters expressed specific concerns regarding moving 
the FDA marketing authorization deadline to May 1 and the impact it 
would have on how long technologies may be eligible for new technology 
add-on payment. Several of the commenters asserted that this policy 
change would prevent a 3-year new technology add-on payment duration 
for almost all applicants, as only those technologies that receive FDA 
marketing authorization in April would be eligible for 3 years of new 
technology add-on payments, shortening the window from 3 months under 
the former policy (April 1 until July 1) to just 1 month (April 1 until 
May 1) (88 FR 58954). In response, we noted in that even under the 
former policy, not all applicants receive the full 3 years of new 
technology add on payments, and that there are many factors (including 
timing of interactions with the FDA and manufacturing readiness) that 
can delay a technology's approval by the FDA that would disrupt a 
technology's ability to receive the full 3 years of payment. However, 
we also noted the commenters' concerns regarding the shortened time 
period between April 1 and May 1 under the new policy and stated that 
we would consider for future rulemaking how we assess new technology 
add-on payment eligibility in the third year of newness, such as 
consideration of adjusting the April 1 cutoff to allow for a longer 
window of eligibility (88 FR 58955).
    After further consideration of commenters' concerns that the policy 
we finalized in the FY 2024 IPPS/LTCH PPS final rule may limit the 
ability of new technology add-on payment applicants to be eligible for 
a third year of new technology add-on payments due to the shortened 
timeframe between April 1 and May 1, we agree that there may be merit 
to modifying our current 6-month guideline to provide additional 
flexibility for applications submitted in accordance with this new 
policy. While technologies that are FDA approved or cleared in April, 
and technologies with a documented delay in availability on the U.S. 
market such that the product's entry onto the U.S. market falls within 
the second half of the fiscal year, would still be eligible for a third 
year of new technology add-on payments under current policy, we agree 
that the change in the FDA marketing authorization deadline from July 1 
to May 1 may limit the ability of new technology add-on payment 
applicants to be eligible for 3 years of new technology add-on 
payments. Therefore, we are proposing to change the April 1 cutoff for 
determining whether a technology would be within its 2- to 3-year 
newness period when considering eligibility for

[[Page 36137]]

new technology add-on payments. We believe this proposed change would 
continue the flexibility applicants had with respect to when they apply 
to FDA and when they apply for new technology add-on payment, while 
preserving a predictable and consistent payment methodology for new 
technologies throughout the fiscal year.
    Specifically, we are proposing that beginning with new technology 
add-on payments for FY 2026, in assessing whether to continue the new 
technology add-on payments for those technologies that are first 
approved for new technology add-on payments in FY 2025 or a subsequent 
year, we would extend new technology add-on payments for an additional 
fiscal year when the three-year anniversary date of the product's entry 
onto the U.S. market occurs on or after October 1 of that fiscal year. 
We are proposing that this policy change would become effective 
beginning with those technologies that are initially approved for new 
technology add-on payments in FY 2025 or a subsequent year to allow 
additional flexibility for those applications for new technologies 
which were first subject to the change in the deadline for FDA 
marketing authorization from July 1 to May 1. Therefore, for 
technologies that were first approved for new technology add-on 
payments prior to FY 2025, including for technologies we determine to 
be substantially similar to those technologies, we would continue to 
use the midpoint of the upcoming fiscal year (April 1) when determining 
whether a technology would still be considered ``new'' for purposes of 
new technology add-on payments. Similarly, we are also proposing that 
beginning with applications for new technology add-on payments for FY 
2026, we would use the start of the fiscal year (October 1) instead of 
April 1 to determine whether to approve new technology add-on payment 
for that fiscal year.
    We are seeking public comment on our proposal to change the April 1 
cutoff to October 1 for determining whether a technology would be 
within its 2- to 3-year newness period when considering eligibility for 
new technology add-on payments, beginning in FY 2026, effective for 
those technologies that are approved for new technology add-on payments 
starting in FY 2025 or a subsequent year.
8. Proposed Change to the Requirements Defining an Active FDA Marketing 
Application for the Purpose of New Technology Add-On Payment 
Application Eligibility
    As previously discussed, in the FY 2024 IPPS/LTCH PPS final rule 
(88 FR 58948 through 58958), we finalized that beginning with the new 
technology add-on payment applications for FY 2025, for technologies 
that are not already FDA market authorized for the indication that is 
the subject of the new technology add-on payment application, 
applicants must have a complete and active FDA market authorization 
request at the time of new technology add-on payment application 
submission, and must provide documentation of FDA acceptance or filing 
to CMS at the time of application submission, consistent with the type 
of FDA marketing authorization application the applicant has submitted 
to FDA. See Sec.  412.87(e) and further discussion in the FY 2024 IPPS/
LTCH PPS final rule (88 FR 58948 through 58958).
    As we discussed further in the FY 2024 IPPS/LTCH PPS final rule, 
the documentation of FDA acceptance or filing of a marketing 
authorization request must be provided at the time of new technology 
add-on payment application, and be consistent with the type of FDA 
marketing authorization the applicant has submitted to FDA. We stated 
that we only accept new technology add-on payment applications once FDA 
has received all of the information necessary to determine whether it 
will accept (such as in the case of a 510(k) premarket submission or De 
Novo Classification request) or file (such as in the case of a PMA, 
NDA, or BLA) the application as demonstrated by documentation of the 
acceptance/filing that is provided by FDA. The applicant is required to 
submit documentation with its new technology add-on payment application 
to demonstrate that FDA has determined that the application is 
sufficiently complete to allow for substantive review by the FDA (88 FR 
58955).
    We also explained that, for the purposes of new technology add-on 
payment applications, we consider an FDA marketing authorization 
application to be in an active status when it has not been withdrawn, 
is not the subject of a Complete Response Letter or final decision from 
FDA to refuse to approve the application, and is not on hold (88 FR 
58955 through 58956).
    As noted in the FY 2024 final rule, we collaborated with FDA in 
developing the terminology used for purposes of this policy, and the 
intent behind using the terms we did was to ensure that the requirement 
could apply to and be inclusive of the various FDA applications and 
approval pathways for different types of drugs and devices. As such, we 
did not use terms defined in statute or existing regulations or terms 
defined by FDA (88 FR 58955). While FDA may consider an application for 
an FDA marketing authorization to be under active review despite a hold 
status, under our current policy we do not consider marketing 
authorization applications in a hold status with FDA to be in an active 
status for the purposes of new technology add-on payment application 
eligibility. As discussed in the FY 2024 IPPS/LTCH PPS final rule (88 
FR 58956) our intent with respect to considering applications that are 
on hold at the time of new-technology add-on payment application 
submission to be inactive was to ensure that applicants are far enough 
along in the FDA review process that applicants would be able to 
reasonably provide sufficient information at the time of new technology 
add on payment application for CMS to identify critical questions 
regarding the technology's eligibility for add-on payments and to allow 
the public to assess the relevant new technology evaluation criteria in 
the proposed rule. As noted in the FY 2024 final rule (88 FR 58956), we 
have received applications over the years for technologies that are in 
a hold status with up to 360 days allowed for submission of additional 
information.
    We also recognize that applications for FDA marketing authorization 
may go in and out of a hold status at various stages during the FDA 
application process and for various reasons. The maximum length of a 
hold status can vary based on the FDA approval pathway, such that the 
time remaining for an applicant to resolve the hold may vary from days 
to several months after the start of the new technology add-on payment 
application cycle, depending on the FDA pathway, reason(s) for the hold 
status, and how the timing of the hold coincides with the annual new 
technology add-on payment application submission date. Additionally, 
FDA may need to issue secondary letters of request for additional 
information, often depending on the quality of initial response from 
the applicant. Accordingly, while we continue to believe that an 
application that is in a hold status with FDA pending additional 
information may lack critical information that is needed to evaluate 
whether the technology meets the eligibility criteria, we also 
recognize the

[[Page 36138]]

variability in the reasons for a hold status and the varying lengths of 
time for which an application can be on hold with FDA, such that some 
applicants may be farther along in the process to obtain FDA marketing 
authorization at the time of the hold.
    After further consideration, based on the variability in the timing 
of and reasons underlying hold statuses with FDA, we believe it is 
appropriate to propose to update our policy. Specifically, we are 
proposing, beginning with new technology add-on payment applications 
for FY 2026, to no longer consider a hold status to be an inactive 
status for the purposes of eligibility for the new technology add-on 
payment. We would continue to consider an application to be in an 
inactive status where it is withdrawn, the subject of a Complete 
Response Letter, or the subject of a final decision from FDA to refuse 
to approve the application. Because of the variety of circumstances for 
which a technology may be in a hold status, as previously discussed, we 
note that we may reassess this policy for future years, if finalized, 
based on ongoing experience.
    We invite public comments on our proposal to no longer consider a 
hold status to be an inactive status for the purposes of eligibility 
for new technology add-on payment, beginning with new technology add-on 
payment applications for FY 2026.
9. Proposed Change to the Calculation of the Inpatient New Technology 
Add-On Payment for Gene Therapies Indicated for Sickle Cell Disease
    As discussed previously in this section, section 
1886(d)(5)(K)(ii)(I) of the Act specifies that a new medical service or 
technology may be considered for a new technology add-on payment if, 
based on the estimated costs incurred with respect to discharges 
involving such service or technology, the DRG prospective payment rate 
otherwise applicable to such discharges under this subsection is 
inadequate. Under our current policy, as set forth in Sec.  
412.88(b)(2), unless the discharge qualifies for an outlier payment, 
the additional Medicare payment will be limited to the full MS-DRG 
payment plus 65 percent (or 75 percent for a medical product designated 
by the FDA as a Qualified Infectious Disease Product [QIDP] or approved 
under FDA's Limited Population Pathway for Antibacterial and Antifungal 
Drugs [LPAD]) of the estimated costs of the new technology or medical 
service.
    Since establishing the new technology add-on payment, we have been 
cautious about increasing the new technology add-on payment percentage. 
As stated in the May 4, 2001 proposed rule (66 FR 22695), we believe 
limiting the new technology add-on payment percentage would provide 
hospitals an incentive for continued cost-effective behavior in 
relation to the overall costs of the case. In the FY 2020 IPPS/LTCH PPS 
final rule, in adopting the general increase in the new technology add-
on payment percentage from 50 percent to 65 percent, we stated that we 
believed that 65 percent would be an incremental increase that would 
reasonably balance the need to maintain the incentives inherent to the 
prospective payment system while also encouraging the development and 
use of new technologies. We continue to believe that it is important to 
balance these incentives in assessing any potential change to the new 
technology add-on payment calculation.
    In the FY 2020 IPPS/LTCH PPS final rule, we also finalized an 
increase in the new technology add-on payment percentage for QIDPs from 
65 percent to 75 percent. We stated that we shared commenters' concerns 
related to antimicrobial resistance and its serious impact on Medicare 
beneficiaries and public health overall. We noted that the Centers for 
Disease Control and Prevention (CDC) described antimicrobial resistance 
as ``one of the biggest public health challenges of our time.'' We 
stated that we believe that Medicare beneficiaries may be 
disproportionately impacted by antimicrobial resistance due in large 
part to the unique vulnerability to drug-resistant infections (for 
example, due to age-related and/or disease-related immunosuppression, 
greater pathogen exposure from via catheter use) among individuals aged 
65 or older. We further stated that antimicrobial resistance results in 
a substantial number of additional hospital days for Medicare 
beneficiaries, resulting in significant unnecessary health care 
expenditures.
    To address the continued issues related to antimicrobial resistance 
resulting in a substantial number of increased hospital days and 
significant unnecessary health care expenditures for Medicare 
beneficiaries, in the FY 2021 IPPS/LTCH PPS final rule, we finalized a 
proposal to expand the alternative new technology add-on payment 
pathway for QIDPs to include products approved under the LPAD pathway 
and to increase the maximum new technology add-on payment percentage 
for a product approved under FDA's LPAD pathway, from 65 percent to 75 
percent, consistent with the new technology add-on payment percentage 
for a product that is designated by FDA as a QIDP, beginning with 
discharges occurring on or after October 1, 2020 (85 FR 58739).
    Since finalizing our current policy for QIDPs and LPADs, we 
continue to receive feedback from interested parties regarding the 
adequacy of new technology add-on payments for certain categories of 
technologies, including cell and gene therapies to treat sickle cell 
disease (SCD). Although we still believe it is prudent to proceed 
cautiously with increasing the new technology add-on payment 
percentage, we recognize that SCD, the most common inherited blood 
disorder, has historically had limited treatment options. In addition, 
hospitalizations and other health episodes related to SCD cost the 
health system $3 billion per year.\133\ We further note that the 
administration has identified a need to address SCD and has made a 
commitment to improving outcomes for patients with SCD by facilitating 
access to cell and gene therapies that treat SCD.\134\

    \133\ Biden-Harris Administration Announces Action to Increase 
Access to Sickle Cell Disease Treatments https://www.hhs.gov/about/news/2024/01/30/biden-harris-administration-announces-action-increase-access-sickle-cell-disease-treatments.html.
    \134\ Biden-Harris Administration Announces Action to Increase 
Access to Sickle Cell Disease Treatments https://www.hhs.gov/about/news/2024/01/30/biden-harris-administration-announces-action-increase-access-sickle-cell-disease-treatments.html.
---------------------------------------------------------------------------

    Accordingly, we believe that further facilitating access to these 
gene therapies for Medicare beneficiaries with SCD may have the 
potential to simultaneously improve the health of impacted Medicare 
beneficiaries and potentially lead to long-term savings in the Medicare 
program. We also note that some gene therapies that treat SCD are among 
the costliest treatments to date, and we are concerned about a 
hospital's ability to sustain a potential financial loss to provide 
access to such treatments. As we discussed when we increased the new 
technology add-on payment for QIDPs in the FY 2020 IPPS/LTCH PPS final 
rule and products approved under FDA's LPAD in the FY 2021 IPPS/LTCH 
PPS final rule from 65 percent to 75 percent, we believe that it may be 
appropriate to increase the maximum add-on amount in limited cases 
where the current new technology add-on payment does not provide a 
sufficient incentive for the use of a new technology, which we believe 
may be the case for gene therapies that treat SCD. Accordingly, and 
consistent with our new technology add-on payment policy for products 
designated by the FDA as a QIDP or LPAD, we believe

[[Page 36139]]

there would be merit in also increasing the new technology add-on 
payment percentage for gene therapies that are indicated and used for 
the treatment of SCD to 75 percent.
    Therefore, we are proposing that, subject to our review of the new 
technology add-on payment eligibility criteria, for certain gene 
therapies approved for new technology add-on payments in the FY 2025 
IPPS/LTCH PPS final rule for the treatment of SCD, effective with 
discharges on or after October 1, 2024 and concluding at the end of the 
2- to 3-year newness period for such therapy, if the costs of a 
discharge (determined by applying CCRs as described in Sec.  412.84(h)) 
involving the use of such therapy for the treatment of SCD exceed the 
full DRG payment (including payments for IME and DSH, but excluding 
outlier payments), Medicare would make an add-on payment equal to the 
lesser of: (1) 75 percent of the costs of the new medical service or 
technology; or (2) 75 percent of the amount by which the costs of the 
case exceed the standard DRG payment. We note that, if finalized, these 
payment amounts would only apply to any gene therapy indicated and used 
specifically for the treatment of SCD that CMS determines in the FY 
2025 IPPS/LTCH PPS final rule meets the criteria for approval for new 
technology add-on payment. We are also proposing to add new Sec.  
412.88(a)(2)(ii)(C) and Sec.  412.88(b)(2)(iv) to reflect this proposed 
change to the calculation of the new technology add-on payment amount, 
beginning in FY 2025 and concluding at the end of the 2- to 3-year 
newness period for each such therapy. With this incremental increase, 
we believe hospitals would continue to have an incentive to balance the 
desirability of using the new technology for patients as medically 
appropriate while also maintaining an incentive for continued cost-
effective behavior in relation to the overall costs of the case.
    We invite public comments on this proposal to temporarily increase 
the new technology add-on payment percentage to 75 percent for a gene 
therapy that is indicated and used for the treatment of SCD as 
described previously. We also seek comment on whether we should make 
this proposed 75 percent add-on payment percentage available only to 
applicants that meet certain additional criteria, such as attesting to 
offering and/or participating in outcome-based pricing arrangements 
with purchasers (without regard to whether the specific purchaser 
availed itself of the outcome-based arrangements), or otherwise 
engaging in behaviors that promote access to these therapies at lower 
cost.

III. Proposed Changes to the Hospital Wage Index for Acute Care 
Hospitals

A. Background

1. Legislative Authority
    Section 1886(d)(3)(E) of the Act requires that, as part of the 
methodology for determining prospective payments to hospitals, the 
Secretary adjust the standardized amounts for area differences in 
hospital wage levels by a factor (established by the Secretary) 
reflecting the relative hospital wage level in the geographic area of 
the hospital compared to the national average hospital wage level. We 
currently define hospital labor market areas based on the delineations 
of statistical areas established by the Office of Management and Budget 
(OMB). A discussion of the proposed FY 2025 hospital wage index based 
on the statistical areas appears under section III.B. of the preamble 
of this proposed rule.
    Section 1886(d)(3)(E) of the Act requires the Secretary to update 
the wage index annually and to base the update on a survey of wages and 
wage-related costs of short-term, acute care hospitals. CMS collects 
these data on the Medicare cost report, CMS Form 2552-10, Worksheet S-
3, Parts II, III, IV. The OMB control number for this information 
collection request is 0938-0050, which expires on September 30, 2025. 
Section 1886(d)(3)(E) of the Act also requires that any updates or 
adjustments to the wage index be made in a manner that ensures that 
aggregate payments to hospitals are not affected by the change in the 
wage index. The proposed adjustment for FY 2025 is discussed in section 
II.B. of the Addendum to this proposed rule.
    As discussed in section III.I. of the preamble of this proposed 
rule, we also take into account the geographic reclassification of 
hospitals in accordance with sections 1886(d)(8)(B) and 1886(d)(10) of 
the Act when calculating IPPS payment amounts. Under section 
1886(d)(8)(D) of the Act, the Secretary is required to adjust the 
standardized amounts so as to ensure that aggregate payments under the 
IPPS after implementation of the provisions of sections 1886(d)(8)(B), 
1886(d)(8)(C), and 1886(d)(10) of the Act are equal to the aggregate 
prospective payments that would have been made absent these provisions. 
The proposed budget neutrality adjustment for FY 2025 is discussed in 
section II.A.4.b. of the Addendum to this proposed rule.
    Section 1886(d)(3)(E) of the Act also provides for the collection 
of data every 3 years on the occupational mix of employees for short-
term, acute care hospitals participating in the Medicare program, in 
order to construct an occupational mix adjustment to the wage index. 
(The OMB control number for approved collection of this information is 
0938-0907, which expires on January 31, 2026.) A discussion of the 
occupational mix adjustment that we are proposing to apply to the FY 
2025 wage index appears under section III.E. of the preamble of this 
proposed rule.
2. Proposed Core-Based Statistical Areas (CBSAs) for the FY 2025 
Hospital Wage Index
    The wage index is calculated and assigned to hospitals on the basis 
of the labor market area in which the hospital is located. Under 
section 1886(d)(3)(E) of the Act, beginning with FY 2005 (69 FR 49026 
through 49032), we delineate hospital labor market areas based on OMB-
established Core-Based Statistical Areas (CBSAs). The current 
statistical areas (which were implemented beginning with FY 2021) are 
based on revised OMB delineations issued on Sept 14, 2018, in OMB 
Bulletin No. 18-04.\135\ OMB Bulletin No. 18-04 established revised 
delineations for Metropolitan Statistical Areas, Micropolitan 
Statistical Areas, and Combined Statistical Areas in the United States 
and Puerto Rico based on the 2010 Census and the American Community 
Survey (ACS) and Census Bureau population estimates for 2015.
---------------------------------------------------------------------------

    \135\ We note that while OMB Bulletin 20-01 superseded Bulletin 
No. 18-04, it included no changes that required CMS to formally 
adopt the revisions.
---------------------------------------------------------------------------

    Historically, OMB issued major revisions to statistical areas every 
10 years, based on the results of the decennial census and occasionally 
issues minor updates and revisions to statistical areas in the years 
between the decennial censuses through OMB Bulletins. On February 28, 
2013, OMB issued Bulletin No. 13-01. CMS adopted these delineations, 
based on the results of the 2010 census, effective beginning with the 
FY 2015 IPPS wage index (79 FR 49951 through 49957). OMB subsequently 
issued Bulletin No. 15-01 on July 15, 2015, followed by OMB Bulletin 
No. 17-01 on August 15, 2017, which provided updates to and superseded 
OMB Bulletin No. 15-01. The attachments to OMB Bulletin No. 17-01 
provided detailed information on the update to statistical areas since 
July 15, 2015 and were based on the

[[Page 36140]]

application of the 2010 Standards for Delineating Metropolitan and 
Micropolitan Statistical Areas to Census Bureau population estimates 
for July 1, 2014 and July 1, 2015. In the FY 2019 IPPS/LTCH PPS final 
rule (83 FR 41362 through 41363), we adopted the updates set forth in 
OMB Bulletin No. 17-01 effective October 1, 2018, beginning with the FY 
2019 wage index. OMB Bulletin No. 17-01 was superseded by the April 10, 
2018 OMB Bulletin No. 18-03, and then by the September 14, 2018 OMB 
Bulletin No. 18-04. These bulletins established revised delineations 
for Metropolitan Statistical Areas, Micropolitan Statistical Areas, and 
Combined Statistical Areas, and provided guidance on the use of the 
delineations of these statistical areas. In FY 2021, we adopted the 
updates set forth in OMB Bulletin No. 18-04 (85 FR 58743 through 
58753). Thus, most recently in the FY 2024 IPPS/LTCH PPS final rule, we 
continued to use the OMB delineations that were adopted beginning with 
FY 2015 (based on the revised delineations issued in OMB Bulletin No. 
13-01) to calculate the area wage indexes, with updates as reflected in 
OMB Bulletin Nos. 15-01, 17-01, and 18-04.
    In the July 16, 2021 Federal Register (86 FR 37777), OMB finalized 
a schedule for future updates based on results of the decennial Census 
updates to commuting patterns from the ACS. In accordance with that 
schedule, on July 21, 2023, OMB released Bulletin No. 23-01. A copy of 
OMB Bulletin No. 23-01 may be obtained at https://www.whitehouse.gov/wp-content/uploads/2023/07/OMB-Bulletin-23-01.pdf. According to OMB, 
the delineations reflect the 2020 Standards for Delineating Core Based 
Statistical Areas (``the 2020 Standards''), which appeared in the 
Federal Register on July 16, 2021 (86 FR 37770 through 37778), and the 
application of those standards to Census Bureau population and journey-
to-work data (that is, 2020 Decennial Census, American Community 
Survey, and Census Population Estimates Program data).

B. Proposed Implementation of Revised Labor Market Area Delineations

    We believe that using the revised delineations based on OMB 
Bulletin No. 23-01 will increase the integrity of the IPPS wage index 
system by creating a more accurate representation of current geographic 
variations in wage levels. Therefore, we are proposing to implement the 
revised OMB delineations as described in the July 21, 2023 OMB Bulletin 
No. 23-01, beginning with the FY 2025 IPPS wage index. We are proposing 
to use these revised delineations to calculate area wage indexes in a 
manner that is generally consistent with the CMS' implementation of 
CBSA-based wage index methodologies.
    CMS has recognized that hospitals in certain areas may experience a 
negative impact on their IPPS payment due to the proposed adoption of 
the revised OMB delineations and has finalized transition policies to 
mitigate negative financial impacts and provide stability to year-to-
year wage index variations. We refer readers to the FY 2015 IPPS final 
rule (79 FR 49956 through 49962) for discussion of the transition 
period finalized the last time CMS adopted revised OMB delineations 
after a decennial census. In the FY 2020 final rule (84 FR 42336-
42337), CMS finalized a wage index transition policy to apply a 5 
percent cap on any decrease that hospitals may experience in their 
final wage index from the prior fiscal year. In FY 2023, the 5 percent 
cap policy was made permanent for all acute care hospitals. This 5 
percent cap on reductions policy is discussed in further detail in 
section III.G.6 of the preamble of this proposed rule. We believe it is 
important for the IPPS to use the updated labor market area 
delineations in order to maintain a more accurate and up-to date 
payment system that reflects the reality of current labor market 
conditions. We believe the 5 percent cap policy will sufficiently 
mitigate significant disruptive financial impacts on hospitals that are 
negatively affected by the proposed adoption of the revised OMB 
delineations and thus, we are not proposing a transition period for 
these hospitals.
1. Micropolitan Statistical Areas
    The OMB ``2020 Standards'' define a ``Micropolitan Statistical 
Area'' as being associated with at least one urban area that has a 
population of at least 10,000, but less than 50,000. A Micropolitan 
Statistical Area comprises the central county or counties containing 
the core, plus adjacent outlying counties having a high degree of 
social and economic integration with the central county or counties as 
measured through commuting (86 FR 37778). We refer to these areas as 
Micropolitan Areas. Since FY 2005, we have treated Micropolitan Areas 
as rural and included hospitals located in Micropolitan Areas in each 
State's rural wage index. We refer readers to the FY 2005 IPPS final 
rule (69 FR 49029 through 49032) and the FY 2015 IPPS/LTCH PPS final 
rule (79 FR 49952) for a complete discussion regarding this policy and 
our rationale for treating Micropolitan Areas as rural. Based upon the 
new 2020 Decennial Census data, a number of urban counties have 
switched status and have joined or became Micropolitan Areas, and some 
counties that once were part of a Micropolitan Area, under current OMB 
delineations, have become urban. Overall, there are a similar number of 
Micropolitan Areas (542) under the new OMB delineations based on the 
2020 Census as existed under the latest data from the 2010 Census 
(541). We believe that the best course of action would be to continue 
the policy established in the FY 2005 IPPS final rule and include 
hospitals located in Micropolitan Areas in each State's rural wage 
index. These areas continue to be defined as having relatively small 
urban cores (populations of 10,000-49,999). We do not believe it would 
be appropriate to calculate a separate wage index for areas that 
typically may include only a few hospitals for the reasons set forth in 
the FY 2005 IPPS/LTCH PPS final rule (69 FR 49029 through 49032) and 
the FY 2015 IPPS final rule (79 FR 49952). Therefore, in conjunction 
with our proposal to implement the new OMB statistical area 
delineations beginning in FY 2025, we are proposing to continue to 
treat Micropolitan Areas as ``rural'' and to include Micropolitan Areas 
in the calculation of each state's rural wage index.
2. Metropolitan Divisions
    According to OMB's ``2020 Standards'' (86 FR 37776), a metropolitan 
division is a county or group of counties within a metropolitan 
statistical area (MSA) with a population of at least 2.5 million. Thus, 
MSAs may be subdivided into metropolitan divisions. A county qualifies 
as a ``main county'' of a metropolitan division if 65 percent or more 
of workers living in the county also work within the county and the 
ratio of the number of workers working in the county to the number of 
workers living in the county is at least 0.75. A county qualifies as a 
``secondary county'' if 50 percent or more, but less than 65 percent, 
of workers living in the county also work within the county and the 
ratio of the number of workers working in the county to the number of 
workers living in the county is at least 0.75. After all the main and 
secondary counties are identified and grouped, each additional county 
that already has qualified for inclusion in the MSA falls within the 
metropolitan division associated with the main/secondary county or 
counties with which the county at issue has the highest employment 
interchange measure. Counties in a metropolitan division must be 
contiguous. In the FY 2005

[[Page 36141]]

IPPS final rule (69 FR 49029), CMS finalized our policy to use the 
metropolitan divisions where applicable under the CBSA definitions. CMS 
concluded that including the metropolitan divisions in the CBSA 
definitions most closely approximated the labor market delineation from 
the ``Primary Metropolitan Statistical Areas'' delineations in place 
prior to FY 2005.
    Under the current delineations, 11 MSAs are subdivided into a total 
of 31 metropolitan divisions. The revised OMB delineations have 
subdivided two additional existing MSAs into metropolitan divisions 
relative to the previous delineations. Under the proposed delineations, 
13 MSAs (the 11 currently subdivided MSAs plus two additional MSAs) are 
subdivided into 37 metropolitan divisions. Since the configurations of 
most subdivided MSAs remain substantially similar in the revised 
delineations compared to those used in FY 2024, in order to maintain 
continuity and predictability in labor market delineations, we are 
proposing to continue our policy to include metropolitan divisions as 
separate CBSAs for wage index purposes.
3. Change to County-Equivalents in the State of Connecticut
    In a June 6, 2022 Notice (87 FR 34235 through 34240), the Census 
Bureau announced that it was implementing the State of Connecticut's 
request to replace the 8 counties in the State with 9 new ``Planning 
Regions.'' Planning regions now serve as county-equivalents within the 
CBSA system. OMB Bulletin No. 23-01 is the first set of revised 
delineations that referenced the new county-equivalents for 
Connecticut. We have evaluated the change in hospital assignments for 
Connecticut hospitals and are proposing to adopt the planning regions 
as county equivalents for wage index purposes. As all forthcoming 
county-based delineation data will utilize these new county-equivalent 
definitions for the Connecticut, we believe it is necessary to adopt 
this migration from counties to planning region county-equivalents in 
order to maintain consistency with OMB Bulletin No. 23-01 and future 
OMB updates. We are providing the following crosswalk for each hospital 
in Connecticut with the current and proposed FIPS county and county-
equivalent codes and CBSA assignments.
BILLING CODE 4120-01-P
[GRAPHIC] [TIFF OMITTED] TP02MY24.142


[[Page 36142]]


[GRAPHIC] [TIFF OMITTED] TP02MY24.143

    We note that we are proposing that the remote location currently 
indicated with 07B033 will be located in the same CBSA as the main 
provider 070033. Therefore, consistent with the policy for remote 
locations of multicampus hospitals discussed in FY 2019 IPPS/LTCH PPS 
final rule (83 FR 41369 through 41374), it will no longer be necessary 
to identify this remote location separately from the main provider for 
wage index purposes.
    We also note, as discussed in Section III.B.3 of the preamble of 
this proposed rule, we propose to add both of the newly proposed rural 
planning areas in Connecticut to the list of ``Lugar'' counties.
4. Urban Counties That Would Become Rural Under the Revised OMB 
Delineations
    As previously discussed, we are proposing to implement the revised 
OMB statistical area delineations (based upon OMB Bulletin No. 23-01) 
beginning in FY 2025. Our analysis shows that a total of 53 counties 
(and county equivalents) and 33 hospitals that were once considered 
part of an urban CBSA would be considered to be located in a rural 
area, beginning in FY 2025, under these revised OMB delineations. The 
following chart lists the 53 urban counties that would be rural if we 
finalize our proposal to implement the revised OMB delineations. We 
note that there are four cases (CBSA 14100 [Bloomsburg-Berwick, PA], 
CBSA 19180 [Danville, IL], CBSA 20700 [East Stroudsburg, PA], and CBSA 
35100 [New Bern, NC]) where all constituent counties in an urban CBSA 
would become rural under the revised OMB delineations.

BILLING CODE 4120-01-C
    We are proposing that the wage data for all hospitals located in 
the counties listed here would now be considered when calculating their 
respective State's rural wage index. We further refer readers to 
section III.G.6 of the preamble of this proposed rule for a discussion 
of the 5 percent cap policy. We believe that this policy, which caps 
any reduction in wage index values at 5 percent of the hospital's prior 
year wage index value, provides an adequate transition to mitigate 
sudden negative financial impacts due to the adoption of wage index 
policies, including the adoption of revised OMB labor market 
delineations.
    We are also proposing revisions to the list of counties deemed 
urban under section 1886(d)(8)(B) of the Act, which will affect a 
number the hospitals located in these proposed rural counties. We note 
that we are proposing to add 17 of the 53 counties listed here to the 
list of ``Lugar'' counties whose hospitals, pursuant to 1886(d)(8)(B), 
are deemed to be in an urban area. We refer readers to section 
III.F.4.b for further discussion.
    In addition, we note the provisions of Sec.  412.102 of our 
regulations would continue to apply with respect to determining DSH 
payments. Specifically, in the first year after a hospital loses urban 
status, the hospital will receive an adjustment to its DSH payment that 
equals two-thirds of the difference between the urban DSH payments 
applicable to the hospital before its redesignation from urban to rural 
and the rural DSH payments applicable to the hospital subsequent to its 
redesignation from urban to rural. In the second year after a hospital 
loses urban status, the hospital will receive an adjustment to its DSH 
payment that equals one third of the difference between the urban DSH 
payments applicable to the hospital before its redesignation from urban 
to rural and the rural DSH payments applicable to the hospital 
subsequent to its redesignation from urban to rural.
5. Rural Counties That Would Become Urban Under the Revised OMB 
Delineations
    As previously discussed, we are proposing to implement the revised 
OMB statistical area delineations (based upon OMB Bulletin No. 23-01) 
beginning in FY 2025. Analysis of these OMB statistical area 
delineations shows that a total of 54 counties (and county equivalents) 
and 24 hospitals that were located in rural areas would be located in 
urban areas under the revised OMB delineations. The following chart 
lists the 54 rural counties that would be urban if we finalize our 
proposal to implement the revised OMB delineations.

[[Page 36145]]

[GRAPHIC] [TIFF OMITTED] TP02MY24.147

    We are proposing that when calculating the area wage index, the 
wage data for hospitals located in these counties would be included in 
their new respective urban CBSAs. We also note that due to the proposed 
adoption of the revised OMB delineations, some CAHs that were 
previously located in rural areas may be located in urban areas. The 
regulations at Sec. Sec.  412.103(a)(6) and 485.610(b)(5) provide 
affected CAHs with a two-year transition period that begins from the 
date the redesignation becomes effective. The affected CAHs must

[[Page 36147]]

reclassify as rural during this transition period in order to retain 
their CAH status after the two-year transition period ends. We refer 
readers to the FY 2015 IPPS/LTCH final rule (79 FR 50162 through 50163) 
for further discussion of the two-year transition period for CAHs. We 
also note that special statuses limited to hospitals located in rural 
areas (such as MDH or SCH status) may be terminated if hospitals are 
located in proposed urban counties. In these cases, affected hospitals 
should apply for rural reclassification status under Sec.  412.103 
prior to October 1, 2024 to ensure no disruption in status.
6. Urban Counties That Would Move to a Different Urban CBSA Under the 
Revised OMB Delineations
    In addition to rural counties becoming urban and urban counties 
becoming rural, some urban counties would shift from one urban CBSA to 
a new or existing urban CBSA under our proposal to adopt the new OMB 
delineations.
    In some cases, the change in CBSA would extend only to a change in 
name. Revised CBSA names can be found in Table 3 of the addendum of the 
proposed rule. In other cases, the CBSA number also would change. For 
these CBSAs, the list of constituent urban counties in FY 2024 and FY 
2025 would be the same (except in instances where an urban county 
became rural, or a rural county became urban; as discussed in the 
previous section). The following table lists the CBSAs where, under the 
proposed delineations, the CBSA name and number would change but the 
constituent counties would not change (not including instances where an 
urban county became rural, or a rural county became urban).
[GRAPHIC] [TIFF OMITTED] TP02MY24.148

    In some cases, all of the urban counties from a FY 2024 CBSA would 
be moved and subsumed by another CBSA in FY 2025. The following table 
lists the CBSAs that, under the proposed delineations, would be 
subsumed by an another CBSA.
[GRAPHIC] [TIFF OMITTED] TP02MY24.149

    In other cases, if we adopt the revised OMB delineations, some 
counties would shift between existing and new CBSAs, changing the 
constituent makeup of the CBSAs. For example, Calvert County, MD would 
move from the current CBSA 12580 (Washington-Arlington-Alexandria, DC-
VA-MD-WV) into proposed CBSA 30500 (Lexington Park, MD). The other 
constituent counties of CBSA 12580 would be split into urban CBSAs 
47664 (Washington, DC-MD) and 11694 (Arlington-Alexandria-Reston, VA-
WV). The following chart lists the urban counties that would split off 
from one urban CBSA and move to a newly proposed or modified urban CBSA 
if we adopt the revised OMB delineations.

[[Page 36148]]

[GRAPHIC] [TIFF OMITTED] TP02MY24.152

    If hospitals located in these counties move from one CBSA to 
another under the revised OMB delineations, there may be impacts, both 
negative and positive, upon their specific wage index values. We refer 
readers to section III.F.3. of the preamble of this proposed rule for 
discussion of our proposals to address the reassignment of MGCRB wage 
index reclassifications for hospitals currently assigned to these 
modified CBSAs.
7. Transition
    Overall, we believe implementing the new OMB labor market area 
delineations would result in wage index values being more 
representative of the actual current costs of labor in a given area. 
However, we recognize that some hospitals would experience decreases in 
wage index values as a result of our proposed implementation of the new 
labor market area delineations. We also realize that some hospitals 
would have higher wage index values due to our proposed implementation 
of the new labor market area delineations.
    In the past, we have provided for transition periods when adopting 
changes that have significant payment implications, particularly large 
negative impacts. When adopting new OMB delineations based on the 
decennial census for the 2005 and 2015 wage indexes, we applied a 3-
year transition for urban hospitals that became rural under the new 
delineations and a 50/50 blended wage index adjustment for all 
hospitals that would experience any decrease in their actual payment 
wage index (69 FR 49032 through 49034 and 79 FR 28060 through 28062).
    In connection with our adoption in FY 2021 of the updates in OMB 
Bulletin 18-04, which included more modifications to the CBSAs than are 
typical for OMB bulletins issued between decennial censuses, we adopted 
a policy to place a 5-percent cap on any decrease in a hospital's wage 
index from the hospital's final wage index in FY 2020 so that a 
hospital's final wage index for FY 2021 would not be less than 95 
percent of its final wage index for FY 2020 (85 FR 58753 through 
58755). Given the unprecedented nature of the COVID-19 public health 
emergency (PHE), we adopted a policy in the FY 2022 IPPS/LTCH PPS final 
rule (86 FR 45164 through 45165) to apply an extended transition to the 
FY 2022 wage index for hospitals affected by the transition in FY 2021 
to mitigate significant negative impacts of, and provide additional 
time for hospitals to adapt to, the CMS decision to adopt the revised 
OMB delineations. In the FY 2023 IPPS/LTCH PPS final rule (87 FR 49018 
through 49021), under the authority at sections 1886(d)(3)(E) and 
1886(d)(5)(I)(i) of the Act, we finalized a policy for FY 2023 and 
subsequent years to apply a 5 percent cap on any decrease to a 
hospital's wage index from its wage index in the prior FY, regardless 
of the circumstances causing the decline.
    We believe that this permanent cap policy, reflected at 42 CFR 
412.64(h)(7) and discussed in section in III.G.6. of the preamble of 
this proposed rule, sufficiently mitigates any large negative impacts 
of adopting the new delineations. As we stated when finalizing the 
permanent 5-percent cap policy in the FY 2023 IPPS/LTCH PPS final rule 
(87 FR 49018 through 49021), we further considered the comments we 
received during the FY 2022 rulemaking recommending a permanent 5 
percent cap policy to prevent large year-to-year variations in wage 
index values as a means to reduce overall volatility for hospitals. We 
do not believe any additional transition period is necessary 
considering that the current cap on wage index decreases, which was not 
in place when we implemented the decennial census updates in FY 2005 
and FY 2015, ensures that a hospital's wage index would not be less 
than 95 percent of its final wage index for the prior year.

C. Worksheet S-3 Wage Data for the Proposed FY 2025 Wage Index

1. Cost Reporting Periods Beginning in FY 2021 for FY 2025 Wage Index
    The proposed FY 2025 wage index values are based on the data 
collected from the Medicare cost reports submitted by hospitals for 
cost reporting periods beginning in FY 2021 (the FY 2024 wage indexes 
were based on data from cost reporting periods beginning during FY 
2020).
    The FY 2025 wage index includes all of the following categories of 
data associated with costs paid under the IPPS (as well as outpatient 
costs):
     Salaries and hours from short-term, acute care hospitals 
(including paid lunch hours and hours associated with military leave 
and jury duty).
     Home office costs and hours.
     Certain contract labor costs and hours, which include 
direct patient care, certain top management, pharmacy, laboratory, and 
nonteaching physician Part A services, and certain contract indirect 
patient care services (as discussed in the FY 2008 final rule with 
comment period (72 FR 47315 through 47317)).
     Wage-related costs, including pension costs (based on 
policies adopted in the FY 2012 IPPS/LTCH PPS final rule (76 FR 51586 
through 51590) and modified in the FY 2016 IPPS/LTCH PPS final rule (80 
FR 49505 through 49508)) and other deferred compensation costs.
    Consistent with the wage index methodology for FY 2024, the 
proposed wage index for FY 2025 excludes the direct and overhead 
salaries and hours for services not subject to IPPS payment, such as 
skilled nursing facility (SNF) services, home health services, costs 
related to GME (teaching physicians and residents) and certified 
registered nurse anesthetists (CRNAs), and other subprovider components 
that are not paid under the IPPS. The proposed FY 2025 wage index also 
excludes the salaries, hours, and wage-related costs of hospital-based 
rural health clinics (RHCs), and Federally Qualified Health Centers 
(FQHCs), because Medicare pays for these costs outside of the IPPS (68 
FR 45395). In addition, salaries, hours, and wage-related costs of CAHs 
are excluded from the wage index for the reasons explained in the FY 
2004 IPPS final rule (68 FR 45397 through 45398). Similar to our 
treatment of CAHs, as discussed below, we are proposing to exclude 
Rural Emergency Hospitals (REHs) from the wage index.
    For FY 2020 and subsequent years, other wage-related costs are also 
excluded from the calculation of the wage index. As discussed in the FY 
2019 IPPS/LTCH final rule (83 FR 41365 through 41369), other wage-
related costs reported on Worksheet S-3, Part II, Line 18 and Worksheet 
S-3, Part IV, Line 25 and subscripts, as well as all other wage-related 
costs, such as contract labor costs, are excluded from the calculation 
of the wage index.

[[Page 36151]]

2. Use of Wage Index Data by Suppliers and Providers Other Than Acute 
Care Hospitals Under the IPPS
    Data collected for the IPPS wage index also are currently used to 
calculate wage indexes applicable to suppliers and other providers, 
such as SNFs, home health agencies (HHAs), ambulatory surgical centers 
(ASCs), and hospices. In addition, they are used for prospective 
payments to IRFs, IPFs, and LTCHs, and for hospital outpatient 
services. We note that, in the IPPS rules, we do not address comments 
pertaining to the wage indexes of any supplier or provider except IPPS 
providers and LTCHs. Such comments should be made in response to 
separate proposed rules for those suppliers and providers.
3. Verification of Worksheet S-3 Wage Data
    The wage data for the FY 2025 wage index were obtained from 
Worksheet S-3, Parts II, III and IV of the Medicare cost report, CMS 
Form 2552-10 (OMB Control Number 0938-0050 with an expiration date 
September 30, 2025) for cost reporting periods beginning on or after 
October 1, 2020, and before October 1, 2021. For wage index purposes, 
we refer to cost reports beginning on or after October 1, 2020, and 
before October 1, 2021, as the ``FY 2021 cost report,'' the ``FY 2021 
wage data,'' or the ``FY 2021 data.'' Instructions for completing the 
wage index sections of Worksheet S-3 are included in the Provider 
Reimbursement Manual (PRM), Part 2 (Pub. 15-2), Chapter 40, Sections 
4005.2 through 4005.4. The data file used to construct the proposed FY 
2025 wage index includes FY 2021 data submitted to us as of January 26, 
2024. As in past years, we performed an extensive review of the wage 
data, mostly through the use of edits designed to identify aberrant 
data.
    Consistent with the IPPS and LTCH PPS ratesettings, our policy 
principles with regard to the wage index include generally using the 
most current data and information available, which is usually data on a 
4-year lag (for example, for the FY 2023 wage index we used cost report 
data from FY 2019). We stated in the FY 2023 IPPS/LTCH final rule (87 
FR 48994) that we will be looking at the differential effects of the 
COVID-19 PHE on the audited wage data in future fiscal years. We also 
stated we plan to review the audited wage data, and the impacts of the 
COVID-19 PHE on such data and evaluate these data for future 
rulemaking. For the FY 2025 wage index, the best available data 
typically would be from the FY 2021 wage data.
    In considering the impacts of the COVID-19 PHE on the FY 2021 wage 
data, we compared that data with recent historical data. Based on pre 
reclassified wage data, the changes in the wage data from FY 2020 to FY 
2021 show the following compared to the annual changes for the most 
recent 3 fiscal year periods (that is, FY 2017 to FY 2018, FY 2018 to 
FY 2019 and FY 2019 to FY 2020):
     Approximately 91 percent of hospitals have an increase in 
their average hourly wage (AHW) from FY 2020 to FY 2021 compared to a 
range of 76-86 percent of hospitals for the most recent 3 fiscal year 
periods.
     Approximately 97 percent of all CBSA AHWs are increasing 
from FY 2020 to FY 2021 compared to a range of 84-91 percent of all 
CBSAs for the most recent 3 fiscal year periods.
     Approximately 51 percent of all urban areas have an 
increase in their area wage index from FY 2020 to FY 2021 compared to a 
range of 36-43 percent of all urban areas for the most recent 3 fiscal 
year periods.
     Approximately 55 percent of all rural areas have an 
increase in their area wage index from FY 2020 to FY 2021 compared to a 
range of 31-46 percent of all rural areas for the most recent 3 fiscal 
year periods.
     The unadjusted national average hourly wage increased by a 
range of 2.4-5.4 percent per year from FY 2017-FY 2020. For FY 2021, 
the unadjusted national average hourly increased by 8.7 percent from FY 
2020.
    Similar to the FY 2024 wage index, it is not readily apparent even 
if the comparison with the historical trends had indicated greater 
differences at a national level in this context, how any changes due to 
the COVID-19 PHE differentially impacted the wages paid by individual 
hospitals. Furthermore, even if changes due to the COVID-19 PHE did 
differentially impact the wages paid by individual hospitals over time, 
it is not clear how those changes could be isolated from changes due to 
other reasons and what an appropriate potential methodology might be to 
adjust the data to account for the effects of the COVID-19 PHE.
    Lastly, we also note that we have not identified any significant 
issues with the FY 2021 wage data itself in terms of our audits of this 
data. As usual, the data was audited by the Medicare Administrative 
Contractors (MACs), and there were no significant issues reported 
across the data for all hospitals.
    Taking all of these factors into account, we believe the FY 2021 
wage data is the best available wage data to use for FY 2025 and are 
proposing to use the FY 2021 wage data for FY 2025.
    We welcome comment from the public with regard to the FY 2021 wage 
data. We note, AHW data by provider and CBSA, including the data upon 
which the comparisons provided above are based, is available in our 
Public Use Files released with each proposed and final rule each fiscal 
year. The Public Use Files for the respective FY Wage Index Home Page 
can be found on the Wage Index Files web page at https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps/wage-index-files.
    We requested that our MACs revise or verify data elements that 
resulted in specific edit failures. For the proposed FY 2025 wage 
index, we identified and excluded 69 providers with aberrant data that 
should not be included in the wage index. If data elements for some of 
these providers are corrected, we intend to include data from those 
providers in the final FY 2025 wage index. We also adjusted certain 
aberrant data and included these data in the wage index. For example, 
in situations where a hospital did not have documentable salaries, 
wages, and hours for housekeeping and dietary services, we imputed 
estimates, in accordance with policies established in the FY 2015 IPPS/
LTCH PPS final rule (79 FR 49965 through 49967). We instructed MACs to 
complete their verification of questionable data elements and to 
transmit any changes to the wage data no later than March 20, 2024.
    In constructing the proposed FY 2025 wage index, we included the 
wage data for facilities that were IPPS hospitals in FY 2021, inclusive 
of those facilities that have since terminated their participation in 
the program as hospitals, as long as those data did not fail any of our 
edits for reasonableness. We believe that including the wage data for 
these hospitals is, in general, appropriate to reflect the economic 
conditions in the various labor market areas during the relevant past 
period and to ensure that the current wage index represents the labor 
market area's current wages as compared to the national average of 
wages. However, we excluded the wage data for CAHs as discussed in the 
FY 2004 IPPS final rule (68 FR 45397 through 45398); that is, any 
hospital that is designated as a CAH by 7 days prior to the publication 
of the preliminary wage index public use file (PUF) is excluded from 
the calculation of the wage index. For the proposed rule, we removed 8 
hospitals that converted to CAH status on or after January 23, 2023, 
the cut-off date for

[[Page 36152]]

CAH exclusion from the FY 2024 wage index, and through and including 
January 24, 2024, the cut-off date for CAH exclusion from the FY 2025 
wage index. We note, we also removed 2 hospitals that converted to CAH 
status prior to January 23, 2023.
    The Consolidated Appropriations Act (CAA), 2021, was signed into 
law on December 27, 2020. Section 125 of Division CC (section 125) 
established a new rural Medicare provider type: Rural Emergency 
Hospitals (REHs). (We refer the reader to the CMS website at https://www.cms.gov/medicare/health-safety-standards/guidance-for-laws-regulations/hospitals/rural-emergency-hospitals for additional 
information on REHs.) In doing so, section 125 amended section 1861(e) 
of the Act, which provides the definition of a hospital and states that 
the term ``hospital'' does not include, unless the context otherwise 
requires, a critical access hospital (as defined in subsection (mm)(1)) 
or a rural emergency hospital (as defined in subsection (kkk)(2)). 
Section 125 also added section 1861(kkk) to the Act, which sets forth 
the requirements for REHs. Per section 1861(kkk)(2) of the Act, one of 
the requirements for an REH is that it does not provide any acute care 
inpatient services (other than post-hospital extended care services 
furnished in a distinct part unit licensed as a skilled nursing 
facility (SNF)). Similar to CAHs, we believe hospitals that have 
subsequently converted to REH status should be removed from the wage 
index calculation, because they are a separately certified Medicare 
provider type and are not comparable to other short-term, acute care 
hospitals as they do not provide inpatient hospital services. For FY 
2025, we are proposing to treat REHs the same as CAHs and exclude 15 
REHs from the wage index. Accordingly, similar to our policy on CAHs, 
any hospital that is designated as a REH by 7 days prior to the 
publication of the preliminary wage index public use file (PUF) is 
excluded from the calculation of the wage index. In summary, we 
calculated the FY 2025 wage index using the Worksheet S-3, Parts II and 
III wage data of 3,075 hospitals.
    For the proposed FY 2025 wage index, we allotted the wages and 
hours data for a multicampus hospital among the different labor market 
areas where its campuses are located using campus full-time equivalent 
(FTE) percentages as originally finalized in the FY 2012 IPPS/LTCH PPS 
final rule (76 FR 51591). Table 2, which contains the FY 2025 wage 
index associated with this proposed rule (available via the internet on 
the CMS website), includes separate wage data for the campuses of 27 
multicampus hospitals. The following chart lists the multicampus 
hospitals by CMS certification number (CCN) and the FTE percentages on 
which the wages and hours of each campus were allotted to their 
respective labor market areas:

[[Page 36153]]

[GRAPHIC] [TIFF OMITTED] TP02MY24.153

    We note that, in past years, in Table 2, we have placed a ``B'' to 
designate the subordinate campus in the fourth position of the hospital 
CCN. However, for the FY 2019 IPPS/LTCH PPS proposed and final rules 
and subsequent rules, we have moved the ``B'' to the third position of 
the CCN. Because all IPPS hospitals have a ``0'' in the third position 
of the CCN, we believe that placement of the ``B'' in this third 
position, instead of the ``0'' for the subordinate campus, is the most 
efficient method of identification and interferes the least with the 
other variable digits in the CCN.
4. Process for Requests for Wage Index Data Corrections
a. Process for Hospitals To Request Wage Index Data Corrections
    The preliminary, unaudited Worksheet S-3 wage data files for the 
proposed FY 2025 wage index were made available on May 23, 2023, 
through the internet on the CMS website at https://www.cms.gov/medicare/medicare-fee-service-payment/acuteinpatientpps/wage-index-files/fy-2025-wage-index-home-page. We subsequently identified some 
providers that were inadvertently omitted from the FY 2025 preliminary 
Worksheet S-3 wage data file originally posted on May 23, 2023. 
Therefore, on July 12, 2023, we posted an updated FY 2025 preliminary 
Worksheet S-3 wage data file to include these missing providers. In 
addition, the Calendar Year (CY) 2022 occupational mix survey data was 
made available on July 12, 2023, through the internet on the CMS 
website at https://www.cms.gov/medicare/medicare-fee-service-payment/acuteinpatientpps/wage-index-files/fy-2025-wage-index-home-page. On 
August 14, 2023, we posted an updated CY 2022 Occupational Mix survey 
data file that includes survey data for providers that were 
inadvertently omitted from the file posted on July 12, 2023.
    On January 31, 2024, we posted a public use file (PUF) at https://www.cms.gov/medicare/medicare-fee-service-payment/acuteinpatientpps/wage-index-files/fy-2025-wage-index-home-page containing FY 2025 wage 
index data available as of January 31, 2024. This PUF contains a tab 
with the Worksheet S-3 wage data (which includes Worksheet S-3, Parts 
II and III wage data from cost reporting periods beginning on or after 
October 1, 2020, through September 30, 2021; that is, FY 2021 wage 
data), a tab with the occupational mix data (which includes data from 
the CY 2022 occupational mix survey, Form CMS-10079), a tab containing 
the Worksheet S-3 wage data

[[Page 36154]]

of hospitals deleted from the January 31, 2024 wage data PUF, and a tab 
containing the CY 2022 occupational mix data of the hospitals deleted 
from the January 31, 2024 occupational mix PUF. In a memorandum dated 
January 31, 2024, we instructed all MACs to inform the IPPS hospitals 
that they service of the availability of the January 31, 2024, wage 
index data PUFs, and the process and timeframe for requesting revisions 
in accordance with the FY 2025 Hospital Wage Index Development Time 
Table available at https://www.cms.gov/files/document/fy2025-hospital-wage-index-development-timetable.pdf.
    In the interest of meeting the data needs of the public, beginning 
with the proposed FY 2009 wage index, we post an additional PUF on the 
CMS website that reflects the actual data that are used in computing 
the proposed wage index. The release of this file does not alter the 
current wage index process or schedule. We notify the hospital 
community of the availability of these data as we do with the current 
public use wage data files through our Hospital Open Door Forum. We 
encourage hospitals to sign up for automatic notifications of 
information about hospital issues and about the dates of the Hospital 
Open Door Forums at the CMS website at https://www.cms.gov/Outreach-and-Education/Outreach/OpenDoorForums.
    In a memorandum dated May 4, 2023, we instructed all MACs to inform 
the IPPS hospitals that they service of the availability of the 
preliminary wage index data files and the CY 2022 occupational mix 
survey data files posted on May 23, 2023, and the process and timeframe 
for requesting revisions.
    If a hospital wished to request a change to its data as shown in 
the May 23, 2023, preliminary wage data files and occupational mix data 
files, the hospital had to submit corrections along with complete, 
detailed supporting documentation to its MAC so that the MAC received 
them by September 1, 2023. Hospitals were notified of these deadlines 
and of all other deadlines and requirements, including the requirement 
to review and verify their data as posted in the preliminary wage index 
data files on the internet, through the letters sent to them by their 
MACs.
    November 3, 2023 was the date by when MACs notified State hospital 
associations regarding hospitals that failed to respond to issues 
raised during the desk reviews. Additional revisions made by the MACs 
were transmitted to CMS throughout January 2024. CMS published the wage 
index PUFs that included hospitals' revised wage index data on January 
31, 2024. Hospitals had until February 16, 2024, to submit requests to 
the MACs to correct errors in the January 31, 2024, PUF due to CMS or 
MAC mishandling of the wage index data, or to revise desk review 
adjustments to their wage index data as included in the January 31, 
2024, PUF. Hospitals also were required to submit sufficient 
documentation to support their requests. Hospitals' requests and 
supporting documentation must have been received by the MAC by the 
February deadline (that is, by February 16, 2024, for the FY 2025 wage 
index).
    After reviewing requested changes submitted by hospitals, MACs were 
required to transmit to CMS any additional revisions resulting from the 
hospitals' reconsideration requests by March 20, 2024. Under our 
current policy as adopted in the FY 2018 IPPS/LTCH PPS final rule (82 
FR 38153), the deadline for a hospital to request CMS intervention in 
cases where a hospital disagreed with a MAC's handling of wage data on 
any basis (including a policy, factual, or other dispute) is April 3, 
2024. Data that were incorrect in the preliminary or January 31, 2024, 
wage index data PUFs, but for which no correction request was received 
by the February 16, 2024, deadline, are not considered for correction 
at this stage. In addition, April 3, 2024, is the deadline for 
hospitals to dispute data corrections made by CMS of which the hospital 
was notified after the January 31, 2024, PUF and at least 14 calendar 
days prior to April 3, 2024 (that is, March 20, 2024), that do not 
arise from a hospital's request for revisions. The hospital's request 
and supporting documentation must be received by CMS (and a copy 
received by the MAC) by the April deadline (that is, by April 3, 2024, 
for the FY 2025 wage index). We refer readers to the FY 2025 Hospital 
Wage Index Development Time Table for complete details. Hospitals are 
given the opportunity to examine Table 2 associated with this proposed 
rule, which is listed in section VI. of the Addendum to the proposed 
rule and available via the internet on the CMS website at https://www.cms.gov/medicare/medicare-fee-service-payment/acuteinpatientpps/wage-index-files/fy-2025-wage-index-home-page. Table 2 associated with 
the proposed rule contains each hospital's proposed adjusted average 
hourly wage used to construct the wage index values for the past 3 
years, including the proposed FY 2025 wage index, which was constructed 
from FY 2021 data. We note that the proposed hospital average hourly 
wages shown in Table 2 only reflect changes made to a hospital's data 
that were transmitted to CMS by early February 2024.
    We plan to post the final wage index data PUFs on April 29, 2024, 
on the CMS website at https://www.cms.gov/medicaremedicare-fee-service-paymentacuteinpatientppswage-index-files/fy-2024-wage-index-home-page. 
The April 2024 PUFs are made available solely for the limited purpose 
of identifying any potential errors made by CMS or the MAC in the entry 
of the final wage index data that resulted from the correction process 
(the process for disputing revisions submitted to CMS by the MACs by 
March 20, 2024, and the process for disputing data corrections made by 
CMS that did not arise from a hospital's request for wage data 
revisions as discussed earlier), as previously described.
    After the release of the April 2024 wage index data PUFs, changes 
to the wage and occupational mix data can only be made in those very 
limited situations involving an error by the MAC or CMS that the 
hospital could not have known about before its review of the final wage 
index data files. Specifically, neither the MAC nor CMS will approve 
the following types of requests:
     Requests for wage index data corrections that were 
submitted too late to be included in the data transmitted to CMS by the 
MACs on or before March 20, 2024.
     Requests for correction of errors that were not, but could 
have been, identified during the hospital's review of the January 31, 
2024, wage index PUFs.
     Requests to revisit factual determinations or policy 
interpretations made by the MAC or CMS during the wage index data 
correction process.
    If, after reviewing the April 2024 final wage index data PUFs, a 
hospital believes that its wage or occupational mix data are incorrect 
due to a MAC or CMS error in the entry or tabulation of the final data, 
the hospital is given the opportunity to notify both its MAC and CMS 
regarding why the hospital believes an error exists and provide all 
supporting information, including relevant dates (for example, when it 
first became aware of the error). The hospital is required to send its 
request to CMS and to the MAC so that it is received no later than May 
29, 2024. May 29, 2024, is also the deadline for hospitals to dispute 
data corrections made by CMS of which the hospital is notified on or 
after 13 calendar days prior to April 3, 2024 (that is, March 21, 
2024), and at least 14 calendar days prior to May 29, 2024 (that is, 
May 15, 2024), that did not arise from a hospital's request for

[[Page 36155]]

revisions. (Data corrections made by CMS of which a hospital is 
notified on or after 13 calendar days prior to May 29, 2024 (that is, 
May 16, 2024), may be appealed to the Provider Reimbursement Review 
Board (PRRB)). In accordance with the FY 2025 Hospital Wage Index 
Development Time Table posted on the CMS website at https://www.cms.gov/files/document/fy2025-hospital-wage-index-development-timetable.pdf, the May appeals are required to be submitted to CMS 
through an online submission process or through email. We refer readers 
to the FY 2025 Hospital Wage Index Development Time Table for complete 
details.
    Verified corrections to the wage index data received timely (that 
is, by May 29, 2024) by CMS and the MACs will be incorporated into the 
final FY 2025 wage index, which will be effective October 1, 2024.
    We created the processes previously described to resolve all 
substantive wage index data correction disputes before we finalize the 
wage and occupational mix data for the FY 2025 payment rates. 
Accordingly, hospitals that do not meet the procedural deadlines set 
forth earlier will not be afforded a later opportunity to submit wage 
index data corrections or to dispute the MAC's decision with respect to 
requested changes. Specifically, our policy is that hospitals that do 
not meet the procedural deadlines as previously set forth (requiring 
requests to MACs by the specified date in February and, where such 
requests are unsuccessful, requests for intervention by CMS by the 
specified date in April) will not be permitted to challenge later, 
before the PRRB, the failure of CMS to make a requested data revision. 
We refer readers also to the FY 2000 IPPS final rule (64 FR 41513) for 
a discussion of the parameters for appeals to the PRRB for wage index 
data corrections. As finalized in the FY 2018 IPPS/LTCH PPS final rule 
(82 FR 38154 through 38156), this policy also applies to a hospital 
disputing corrections made by CMS that do not arise from a hospital's 
request for a wage index data revision. That is, a hospital disputing 
an adjustment made by CMS that did not arise from a hospital's request 
for a wage index data revision is required to request a correction by 
the first applicable deadline. Hospitals that do not meet the 
procedural deadlines set forth earlier will not be afforded a later 
opportunity to submit wage index data corrections or to dispute CMS' 
decision with respect to changes.
    Again, we believe the wage index data correction process described 
earlier provides hospitals with sufficient opportunity to bring errors 
in their wage and occupational mix data to the MAC's attention. 
Moreover, because hospitals had access to the final wage index data 
PUFs by late April 2024, they have an opportunity to detect any data 
entry or tabulation errors made by the MAC or CMS before the 
development and publication of the final FY 2025 wage index by August 
2024, and the implementation of the FY 2025 wage index on October 1, 
2024. Given these processes, the wage index implemented on October 1 
should be accurate. Nevertheless, in the event that errors are 
identified by hospitals and brought to our attention after May 29, 
2024, we retain the right to make midyear changes to the wage index 
under very limited circumstances.
    Specifically, in accordance with Sec.  412.64(k)(1) of our 
regulations, we make midyear corrections to the wage index for an area 
only if a hospital can show that: (1) The MAC or CMS made an error in 
tabulating its data; and (2) the requesting hospital could not have 
known about the error or did not have an opportunity to correct the 
error, before the beginning of the fiscal year. For purposes of this 
provision, ``before the beginning of the fiscal year'' means by the May 
deadline for making corrections to the wage data for the following 
fiscal year's wage index (for example, May 29, 2024, for the FY 2025 
wage index). This provision is not available to a hospital seeking to 
revise another hospital's data that may be affecting the requesting 
hospital's wage index for the labor market area. As indicated earlier, 
because CMS makes the wage index data available to hospitals on the CMS 
website prior to publishing both the proposed and final IPPS rules, and 
the MACs notify hospitals directly of any wage index data changes after 
completing their desk reviews, we do not expect that midyear 
corrections will be necessary. However, under our current policy, if 
the correction of a data error changes the wage index value for an 
area, the revised wage index value will be effective prospectively from 
the date the correction is made.
    In the FY 2006 IPPS final rule (70 FR 47385 through 47387 and 
47485), we revised Sec.  412.64(k)(2) to specify that, effective on 
October 1, 2005, that is, beginning with the FY 2006 wage index, a 
change to the wage index can be made retroactive to the beginning of 
the Federal fiscal year only when CMS determines all of the following: 
(1) The MAC or CMS made an error in tabulating data used for the wage 
index calculation; (2) the hospital knew about the error and requested 
that the MAC and CMS correct the error using the established process 
and within the established schedule for requesting corrections to the 
wage index data, before the beginning of the fiscal year for the 
applicable IPPS update (that is, by the May 29, 2024, deadline for the 
FY 2025 wage index); and (3) CMS agreed before October 1 that the MAC 
or CMS made an error in tabulating the hospital's wage index data and 
the wage index should be corrected.
    In those circumstances where a hospital requested a correction to 
its wage index data before CMS calculated the final wage index (that 
is, by the May 29, 2024 deadline for the FY 2025 wage index), and CMS 
acknowledges that the error in the hospital's wage index data was 
caused by CMS' or the MAC's mishandling of the data, we believe that 
the hospital should not be penalized by our delay in publishing or 
implementing the correction. As with our current policy, we indicated 
that the provision is not available to a hospital seeking to revise 
another hospital's data. In addition, the provision cannot be used to 
correct prior years' wage index data; it can only be used for the 
current Federal fiscal year. In situations where our policies would 
allow midyear corrections other than those specified in Sec.  
412.64(k)(2)(ii), we continue to believe that it is appropriate to make 
prospective-only corrections to the wage index.
    We note that, as with prospective changes to the wage index, the 
final retroactive correction will be made irrespective of whether the 
change increases or decreases a hospital's payment rate. In addition, 
we note that the policy of retroactive adjustment will still apply in 
those instances where a final judicial decision reverses a CMS denial 
of a hospital's wage index data revision request.
b. Process for Data Corrections by CMS After the January 31 Public Use 
File (PUF)
    The process set forth with the wage index timetable discussed in 
section III.C.4. of the preamble of this proposed rule allows hospitals 
to request corrections to their wage index data within prescribed 
timeframes. In addition to hospitals' opportunity to request 
corrections of wage index data errors or MACs' mishandling of data, CMS 
has the authority under section 1886(d)(3)(E) of the Act to make 
corrections to hospital wage index and occupational mix data in order 
to ensure the accuracy of the wage index. As we explained in the FY 
2016 IPPS/LTCH PPS final rule (80 FR 49490 through

[[Page 36156]]

49491) and the FY 2017 IPPS/LTCH PPS final rule (81 FR 56914), section 
1886(d)(3)(E) of the Act requires the Secretary to adjust the 
proportion of hospitals' costs attributable to wages and wage-related 
costs for area differences reflecting the relative hospital wage level 
in the geographic areas of the hospital compared to the national 
average hospital wage level. We believe that, under section 
1886(d)(3)(E) of the Act, we have discretion to make corrections to 
hospitals' data to help ensure that the costs attributable to wages and 
wage-related costs in fact accurately reflect the relative hospital 
wage level in the hospitals' geographic areas.
    We have an established multistep, 15-month process for the review 
and correction of the hospital wage data that is used to create the 
IPPS wage index for the upcoming fiscal year. Since the origin of the 
IPPS, the wage index has been subject to its own annual review process, 
first by the MACs, and then by CMS. As a standard practice, after each 
annual desk review, CMS reviews the results of the MACs' desk reviews 
and focuses on items flagged during the desk review, requiring that, if 
necessary, hospitals provide additional documentation, adjustments, or 
corrections to the data. This ongoing communication with hospitals 
about their wage data may result in the discovery by CMS of additional 
items that were reported incorrectly or other data errors, even after 
the posting of the January 31 PUF, and throughout the remainder of the 
wage index development process. In addition, the fact that CMS analyzes 
the data from a regional and even national level, unlike the review 
performed by the MACs that review a limited subset of hospitals, can 
facilitate additional editing of the data the need for which may not be 
readily apparent to the MACs. In these occasional instances, an error 
may be of sufficient magnitude that the wage index of an entire CBSA is 
affected. Accordingly, CMS uses its authority to ensure that the wage 
index accurately reflects the relative hospital wage level in the 
geographic area of the hospital compared to the national average 
hospital wage level, by continuing to make corrections to hospital wage 
data upon discovering incorrect wage data, distinct from instances in 
which hospitals request data revisions.
    We note that CMS corrects errors to hospital wage data as 
appropriate, regardless of whether that correction will raise or lower 
a hospital's average hourly wage. For example, as discussed in section 
III.C. of the preamble of the FY 2019 IPPS/LTCH PPS final rule (83 FR 
41364), in situations where a hospital did not have documentable 
salaries, wages, and hours for housekeeping and dietary services, we 
imputed estimates, in accordance with policies established in the FY 
2015 IPPS/LTCH PPS final rule (79 FR 49965 through 49967). Furthermore, 
if CMS discovers after conclusion of the desk review, for example, that 
a MAC inadvertently failed to incorporate positive adjustments 
resulting from a prior year's wage index appeal of a hospital's wage-
related costs such as pension, CMS would correct that data error, and 
the hospital's average hourly wage would likely increase as a result.
    While we maintain CMS' authority to conduct additional review and 
make resulting corrections at any time during the wage index 
development process, in accordance with the policy finalized in the FY 
2018 IPPS/LTCH PPS final rule (82 FR 38154 through 38156) and as first 
implemented with the FY 2019 wage index (83 FR 41389), hospitals are 
able to request further review of a correction made by CMS that did not 
arise from a hospital's request for a wage index data correction. 
Instances where CMS makes a correction to a hospital's data after the 
January 31 PUF based on a different understanding than the hospital 
about certain reported costs, for example, could potentially be 
resolved using this process before the final wage index is calculated. 
We believe this process and the timeline for requesting review of such 
corrections (as described earlier and in the FY 2018 IPPS/LTCH PPS 
final rule) promote additional transparency in instances where CMS 
makes data corrections after the January 31 PUF and provide 
opportunities for hospitals to request further review of CMS changes in 
time for the most accurate data to be reflected in the final wage index 
calculations. These additional appeals opportunities are described 
earlier and in the FY 2025 Hospital Wage Index Development Time Table, 
as well as in the FY 2018 IPPS/LTCH PPS final rule (82 FR 38154 through 
38156).

D. Method for Computing the Proposed FY 2025 Unadjusted Wage Index

    The method used to compute the proposed FY 2025 wage index without 
an occupational mix adjustment follows the same methodology that we 
used to compute the wage indexes without an occupational mix adjustment 
in the FY 2021 IPPS/LTCH PPS final rule (see 85 FR 58758-58761), and we 
are not proposing any changes to this methodology. We have restated our 
methodology in this section of this rule.
    Step 1.--We gathered data from each of the non-Federal, short-term, 
acute care hospitals for which data were reported on the Worksheet S-3, 
Parts II and III of the Medicare cost report for the hospital's cost 
reporting period relevant to the wage index (in this case, for FY 2025, 
these were data from cost reports for cost reporting periods beginning 
on or after October 1, 2020, and before October 1, 2021). In addition, 
we included data from hospitals that had cost reporting periods 
beginning prior to the October 1, 2020 begin date and extending into FY 
2021 but that did not have any cost report with a begin date on or 
after October 1, 2020 and before October 1, 2021. We include this data 
because no other data from these hospitals would be available for the 
cost reporting period as previously described, and because particular 
labor market areas might be affected due to the omission of these 
hospitals. However, we generally describe these wage data as data 
applicable to the fiscal year wage data being used to compute the wage 
index for those hospitals. We note that, if a hospital had more than 
one cost reporting period beginning during FY 2021 (for example, a 
hospital had two short cost reporting periods beginning on or after 
October 1, 2020, and before October 1, 2021), we include wage data from 
only one of the cost reporting periods, the longer, in the wage index 
calculation. If there was more than one cost reporting period and the 
periods were equal in length, we included the wage data from the later 
period in the wage index calculation.
    Step 2.--Salaries.--The method used to compute a hospital's average 
hourly wage excludes certain costs that are not paid under the IPPS. 
(We note that, beginning with FY 2008 (72 FR 47315), we included what 
were then Lines 22.01, 26.01, and 27.01 of Worksheet S-3, Part II of 
CMS Form 2552-96 for overhead services in the wage index. Currently, 
these lines are lines 28, 33, and 35 on CMS Form 2552-10. However, we 
note that the wages and hours on these lines are not incorporated into 
Line 101, Column 1 of Worksheet A, which, through the electronic cost 
reporting software, flows directly to Line 1 of Worksheet S-3, Part II. 
Therefore, the first step in the wage index calculation is to compute a 
``revised'' Line 1, by adding to the Line 1 on Worksheet S-3, Part II 
(for wages and hours respectively) the amounts on Lines 28, 33, and 
35.) In calculating a hospital's Net Salaries (we note that we 
previously used the term ``average'' salaries in the FY 2012 IPPS/LTCH 
PPS final rule (76 FR 51592), but we now use

[[Page 36157]]

the term ``net'' salaries) plus wage-related costs, we first compute 
the following: Subtract from Line 1 (total salaries) the GME and CRNA 
costs reported on CMS Form 2552-10, Lines 2, 4.01, 7, and 7.01, the 
Part B salaries reported on Lines 3, 5 and 6, home office salaries 
reported on Line 8, and exclude salaries reported on Lines 9 and 10 
(that is, direct salaries attributable to SNF services, home health 
services, and other subprovider components not subject to the IPPS). We 
also subtract from Line 1 the salaries for which no hours were 
reported. Therefore, the formula for Net Salaries (from Worksheet S-3, 
Part II) is the following:

((Line 1 + Line 28 + Line 33 + Line 35)-(Line 2 + Line 3 + Line 4.01 + 
Line 5 + Line 6 + Line 7 + Line 7.01 + Line 8 + Line 9 + Line 10)).

    To determine Total Salaries plus Wage-Related Costs, we add to the 
Net Salaries the costs of contract labor for direct patient care, 
certain top management, pharmacy, laboratory, and nonteaching physician 
Part A services (Lines 11, 12 and 13), home office salaries and wage-
related costs reported by the hospital on Lines 14.01, 14.02, and 15, 
and nonexcluded area wage-related costs (Lines 17, 22, 25.50, 25.51, 
and 25.52). We note that contract labor and home office salaries for 
which no corresponding hours are reported are not included. In 
addition, wage-related costs for nonteaching physician Part A employees 
(Line 22) are excluded if no corresponding salaries are reported for 
those employees on Line 4. The formula for Total Salaries plus Wage-
Related Costs (from Worksheet S-3, Part II) is the following:

((Line 1 + Line 28 + Line 33 + Line 35)-(Line 2 + Line 3 + Line 4.01 + 
Line 5 + Line 6 + Line 7 + Line 7.01 + Line 8 + Line 9 + Line 10)) + 
(Line 11 + Line 12 + Line 13 + Line 14.01 + 14.02 + Line 15) + (Line 17 
+ Line 22 + 25.50 + 25.51 + 25.52).

    Step 3.--Hours.--With the exception of wage-related costs, for 
which there are no associated hours, we compute total hours using the 
same methods as described for salaries in Step 2. The formula for Total 
Hours (from Worksheet S-3, Part II) is the following:

((Line 1 + Line 28 + Line 33 + Line 35)-(Line 2 + Line 3 + Line 4.01 + 
Line 5 + Line 6 + Line 7 + Line 7.01 + Line 8 + Line 9 + Line 10)) + 
(Line 11 + Line 12 + Line 13 + Line 14.01 + 14.02 + Line 15).

    Step 4.--For each hospital reporting both total overhead salaries 
and total overhead hours greater than zero, we then allocate overhead 
costs to areas of the hospital excluded from the wage index 
calculation. First, we determine the ``excluded rate'', which is the 
ratio of excluded area hours to Revised Total Hours (from Worksheet S-
3, Part II) with the following formula:

(Line 9 + Line 10)/(Line 1 + Line 28 + Line 33 + Line 35)-(Lines 2, 3, 
4.01, 5, 6, 7, 7.01, and 8 and Lines 26 through 43).

    We then compute the amounts of overhead salaries and hours to be 
allocated to the excluded areas by multiplying the previously discussed 
ratio by the total overhead salaries and hours reported on Lines 26 
through 43 of Worksheet S-3, Part II. Next, we compute the amounts of 
overhead wage-related costs to be allocated to the excluded areas using 
three steps:
     We determine the ``overhead rate'' (from Worksheet S-3, 
Part II), which is the ratio of overhead hours (Lines 26 through 43 
minus the sum of Lines 28, 33, and 35) to revised hours excluding the 
sum of lines 28, 33, and 35 (Line 1 minus the sum of Lines 2, 3, 4.01, 
5, 6, 7, 7.01, 8, 9, 10, 28, 33, and 35). We note that, for the FY 2008 
and subsequent wage index calculations, we have been excluding the 
overhead contract labor (Lines 28, 33, and 35) from the determination 
of the ratio of overhead hours to revised hours because hospitals 
typically do not provide fringe benefits (wage-related costs) to 
contract personnel. Therefore, it is not necessary for the wage index 
calculation to exclude overhead wage-related costs for contract 
personnel. Further, if a hospital does contribute to wage-related costs 
for contracted personnel, the instructions for Lines 28, 33, and 35 
require that associated wage-related costs be combined with wages on 
the respective contract labor lines. The formula for the Overhead Rate 
(from Worksheet S-3, Part II) is the following:

(Lines 26 through 43-Lines 28, 33 and 35)/((((Line 1 + Lines 28, 33, 
35)-(Lines 2, 3, 4.01, 5, 6, 7, 7.01, 8, and 26 through 43))-;(Lines 9 
and 10)) + (Lines 26 through 43-Lines 28, 33, and 35)).

     We compute overhead wage-related costs by multiplying the 
overhead hours ratio by wage-related costs reported on Part II, Lines 
17, 22, 25.50, 25.51, and 25.52.
     We multiply the computed overhead wage-related costs by 
the previously described excluded area hours ratio.
    Finally, we subtract the computed overhead salaries, wage-related 
costs, and hours associated with excluded areas from the total salaries 
(plus wage-related costs) and hours derived in Steps 2 and 3.
    Step 5.--For each hospital, we adjust the total salaries plus wage-
related costs to a common period to determine total adjusted salaries 
plus wage-related costs. To make the wage adjustment, we estimate the 
percentage change in the employment cost index (ECI) for compensation 
for each 30-day increment from October 14, 2020, through April 15, 
2022, for private industry hospital workers from data obtained from the 
Bureau of Labor Statistics' (BLS') Office of Compensation and Working 
Conditions. We use the ECI because it reflects the price increase 
associated with total compensation (salaries plus fringes) rather than 
just the increase in salaries. In addition, the ECI includes managers 
as well as other hospital workers. This methodology to compute the 
monthly update factors uses actual quarterly ECI data and assures that 
the update factors match the actual quarterly and annual percent 
changes. We also note that, since April 2006 with the publication of 
March 2006 data, the BLS' ECI uses a different classification system, 
the North American Industrial Classification System (NAICS), instead of 
the Standard Industrial Codes (SICs), which no longer exist. We have 
consistently used the ECI as the data source for our wages and salaries 
and other price proxies in the IPPS market basket, and we are not 
proposing to make any changes to the usage of the ECI for FY 2025. The 
factors used to adjust the hospital's data are based on the midpoint of 
the cost reporting period, as indicated in this rule.
    Step 6.--Each hospital is assigned to its appropriate urban or 
rural labor market area before any reclassifications under section 
1886(d)(8)(B), 1886(d)(8)(E), or 1886(d)(10) of the Act. Within each 
urban or rural labor market area, we add the total adjusted salaries 
plus wage-related costs obtained in Step 5 for all hospitals in that 
area to determine the total adjusted salaries plus wage-related costs 
for the labor market area.
    Step 7.--We divide the total adjusted salaries plus wage-related 
costs obtained under Step 6 by the sum of the corresponding total hours 
(from Step 4) for all hospitals in each labor market area to determine 
an average hourly wage for the area.
    Step 8.--We add the total adjusted salaries plus wage-related costs 
obtained in Step 5 for all hospitals in the Nation and then divide the 
sum by the national sum of total hours from Step 4 to arrive at a 
national average hourly wage.

[[Page 36158]]

    Step 9.--For each urban or rural labor market area, we calculate 
the hospital wage index value, unadjusted for occupational mix, by 
dividing the area average hourly wage obtained in Step 7 by the 
national average hourly wage computed in Step 8.
    Step 10.--For each urban labor market area for which we do not have 
any hospital wage data (either because there are no IPPS hospitals in 
that labor market area, or there are IPPS hospitals in that area but 
their data are either too new to be reflected in the current year's 
wage index calculation, or their data are aberrant and are deleted from 
the wage index), we finalized in the FY 2020 IPPS/LTCH PPS final rule 
(84 FR 42305) that, for FY 2020 and subsequent years' wage index 
calculations, such CBSAs' wage index would be equal to total urban 
salaries plus wage-related costs (from Step 5) in the State, divided by 
the total urban hours (from Step 4) in the State, divided by the 
national average hourly wage from Step 8 (see 84 FR 42305 and 42306,). 
We stated that we believe that, in the absence of wage data for an 
urban labor market area, it is reasonable to use a statewide urban 
average, which is based on actual, acceptable wage data of hospitals in 
that State, rather than impute some other type of value using a 
different methodology. For calculation of the proposed FY 2025 wage 
index, we note there is one urban CBSA for which we do not have IPPS 
hospital wage data. In Table 3 (which is available via the internet on 
the CMS website), which contains the area wage indexes, we include a 
footnote to indicate to which CBSA this policy applies. This CBSA's 
wage index would be calculated as described, based on the FY 2020 IPPS/
LTCH PPS final rule methodology (84 FR 42305). Under this step, we also 
apply our policy with regard to how dollar amounts, hours, and other 
numerical values in the wage index calculations are rounded, as 
discussed in this section of this proposed rule.
    We refer readers to section II. of the Appendix of the proposed 
rule for the policy regarding rural areas that do not have IPPS 
hospitals.
    Step 11.--Section 4410 of Public Law 105-33 provides that, for 
discharges on or after October 1, 1997, the area wage index applicable 
to any hospital that is located in an urban area of a State may not be 
less than the area wage index applicable to hospitals located in rural 
areas in that State. The areas affected by this provision are 
identified in Table 2 listed in section VI. of the Addendum to the 
proposed rule and available via the internet on the CMS website.
    Following is our policy with regard to rounding of the wage data 
(dollar amounts, hours, and other numerical values) in the calculation 
of the unadjusted and adjusted wage index, as finalized in the FY 2020 
IPPS/LTCH final rule (84 FR 42306). For data that we consider to be 
``raw data,'' such as the cost report data on Worksheets S-3, Parts II 
and III, and the occupational mix survey data, we use such data ``as 
is,'' and do not round any of the individual line items or fields. 
However, for any dollar amounts within the wage index calculations, 
including any type of summed wage amount, average hourly wages, and the 
national average hourly wage (both the unadjusted and adjusted for 
occupational mix), we round the dollar amounts to 2 decimals. For any 
hour amounts within the wage index calculations, we round such hour 
amounts to the nearest whole number. For any numbers not expressed as 
dollars or hours within the wage index calculations, which could 
include ratios, percentages, or inflation factors, we round such 
numbers to 5 decimals. However, we continue rounding the actual 
unadjusted and adjusted wage indexes to 4 decimals, as we have done 
historically.
    As discussed in the FY 2012 IPPS/LTCH PPS final rule, in ``Step 
5,'' for each hospital, we adjust the total salaries plus wage-related 
costs to a common period to determine total adjusted salaries plus 
wage-related costs. To make the wage adjustment, we estimate the 
percentage change in the ECI for compensation for each 30-day increment 
from October 14, 2020, through April 15, 2022, for private industry 
hospital workers from the BLS' Office of Compensation and Working 
Conditions data. We have consistently used the ECI as the data source 
for our wages and salaries and other price proxies in the IPPS market 
basket, and we are not proposing any changes to the usage of the ECI 
for FY 2025. The factors used to adjust the hospital's data were based 
on the midpoint of the cost reporting period, as indicated in the 
following table.

[[Page 36159]]

[GRAPHIC] [TIFF OMITTED] TP02MY24.154

    For example, the midpoint of a cost reporting period beginning 
January 1, 2021, and ending December 31, 2021, is June 30, 2021. An 
adjustment factor of 1.03606 was applied to the wages of a hospital 
with such a cost reporting period.
    Previously, we also would provide a Puerto Rico overall average 
hourly wage. As discussed in the FY 2017 IPPS/LTCH PPS final rule (81 
FR 56915), prior to January 1, 2016, Puerto Rico hospitals were paid 
based on 75 percent of the national standardized amount and 25 percent 
of the Puerto Rico-specific standardized amount. As a result, we 
calculated a Puerto Rico specific wage index that was applied to the 
labor-related share of the Puerto Rico-specific standardized amount. 
Section 601 of Division O, Title VI (section 601) of the Consolidated 
Appropriations Act, 2016 (Pub. L. 114-113) amended section 
1886(d)(9)(E) of the Act to specify that the payment calculation with 
respect to operating costs of inpatient hospital services of a 
subsection (d) Puerto Rico hospital for inpatient hospital discharges 
on or after January 1, 2016, shall use 100 percent of the national 
standardized amount. As we stated in the FY 2017 IPPS/LTCH PPS final 
rule (81 FR 56915 through 56916), because Puerto Rico hospitals are no 
longer paid with a Puerto Rico specific standardized amount as of 
January 1, 2016, under section 1886(d)(9)(E) of the Act, as amended by 
section 601 of the Consolidated Appropriations Act, 2016, there is no 
longer a need to calculate a Puerto Rico specific average hourly wage 
and wage index. Hospitals in Puerto Rico are now paid 100 percent of 
the national standardized amount and, therefore, are subject to the 
national average hourly wage (unadjusted for occupational mix) and the 
national wage index, which is applied to the national labor-related 
share of the national standardized amount. Therefore, for FY 2025, 
there is no Puerto Rico-specific overall average hourly wage or wage 
index.
    Based on the previously discussed methodology, the proposed FY 2025 
unadjusted national average hourly wage is the following:

E. Proposed Occupational Mix Adjustment to the FY 2025 Wage Index

    As stated earlier, section 1886(d)(3)(E) of the Act provides for 
the collection of data every 3 years on the occupational mix of 
employees for each short-term, acute care hospital participating in the 
Medicare program, in order to construct an occupational mix adjustment 
to the wage index, for application beginning October 1, 2004 (the FY 
2005 wage index). The purpose of the occupational mix adjustment is to 
control for the effect of hospitals' employment choices on the wage 
index. For example, hospitals may choose to employ different 
combinations of registered nurses, licensed practical nurses, nursing 
aides, and medical assistants for the purpose of providing nursing care 
to their patients. The varying labor costs associated with these 
choices reflect hospital management decisions rather than geographic 
differences in the costs of labor.
1. Use of New 2022 Medicare Wage Index Occupational Mix Survey for the 
FY 2025 Wage Index
    Section 304(c) of Appendix F, Title III of the Consolidated 
Appropriations Act, 2001 (Pub. L. 106-554) amended section 
1886(d)(3)(E) of the Act to require CMS to collect data every 3 years 
on the occupational mix of employees for each

[[Page 36160]]

short-term, acute care hospital participating in the Medicare program 
and to measure the earnings and paid hours of employment for such 
hospitals by occupational category. As discussed in the FY 2022 IPPS/
LTCH PPS proposed rule (86 FR 25402 through 25403) and final rule (86 
FR 45173), we collected data in 2019 to compute the occupational mix 
adjustment for the FY 2022, FY 2023, and FY 2024 wage indexes. A new 
measurement of occupational mix is required for FY 2025.
    The FY 2025 occupational mix adjustment is based on a new calendar 
year (CY) 2022 survey. Hospitals were required to submit their 
completed 2022 surveys (Form CMS-10079, OMB Number 0938-0907, 
expiration date January 31, 2026) to their MACs by July 1, 2023. The 
preliminary, unaudited CY 2022 survey data were posted on the CMS 
website on July 12, 2023. As with the Worksheet S-3, Parts II and III 
cost report wage data, as part of the FY 2025 desk review process, the 
MACs revised or verified data elements in hospitals' occupational mix 
surveys that resulted in certain edit failures.
    Consistent with the IPPS and LTCH PPS ratesettings, our policy 
principles with regard to the occupational mix adjustment include 
generally using the most current data and information available, which 
is usually occupational mix data on a 3-year lag in the first year of 
the use of the occupational mix survey (for example, for the FY 2022 
wage index we used occupational mix data from 2019; we also used this 
data for the FY 2023 and FY 2024 wage indexes). In the FY 2024 IPPS/
LTCH final rule (88 FR 58969-58970), one commenter had concerns that 
the 2025 occupational mix data may be skewed due to the COVID-19 PHE, 
and we stated that we plan to assess the CY 2022 Occupational Mix 
Survey data in the FY 2025 IPPS proposed rule.
    Based on pre-reclassified wage data, we computed the unadjusted and 
adjusted wage indexes for FY 2025 using the 2022 occupational mix 
survey data. We then measured the increases and decreases by CBSA as a 
result of the 2022 occupational mix survey data. We compared this table 
to the same table for the FY 2024 wage indexes, which used the 2019 
occupational mix data, as well as the FY 2021 wage indexes, which used 
the 2016 occupational mix data. This table demonstrates the impact of 
the occupational mix adjusted wage data compared to unadjusted wage 
data for the most recent three occupational mix surveys using the 2022 
survey data compared to the 2019 survey data and the 2016 survey data. 
That is, it shows whether hospitals' wage indexes will increase or 
decrease under the 2022 survey data as compared to the most recent 
years using the prior 2019 survey data and 2016 survey data 
respectively.

[[Page 36161]]

[GRAPHIC] [TIFF OMITTED] TP02MY24.156

    Based on the table, increases and decreases by CBSA are alike 
across each year of occupational mix data. For example, 60.19 percent 
of urban areas' wage indexes are increasing in FY 2025 due to the CY 
2022 occupational mix data compared to 56.07 percent in FY 2024 using 
CY 2019 occupational mix data. Similarly, 59.57 percent of rural areas' 
wage indexes are increasing in FY 2025 due to the CY 2022 occupational 
mix data compared to 57.45 percent in FY 2024 using CY 2019 
occupational mix data. We also note that similar to the wage data, it 
is not readily apparent, even if the comparison with the historical 
trends had indicated greater differences by CBSA in this context, how 
any changes due to the COVID-19 PHE differentially impacted the 
occupational mix adjusted wages paid in each CBSA. Furthermore, even if 
hypothetically changes due to the COVID-19 PHE did differentially 
impact the occupational mix adjusted wage index over time, it is not 
clear how those changes could be isolated from changes due to other 
reasons and what an appropriate potential methodology might be to 
adjust the data accordingly.
    Lastly, we also note that we have not identified any significant 
issues with the 2022 occupational mix data itself in terms of our 
audits of this data. As usual, the data was audited by the MACs, and 
there were no significant issues reported across the data for all 
hospitals.
    Taking all these factors into account, we believe the CY 2022 
occupational mix data is the best available data to use for FY 2025 and 
are proposing to use the CY 2022 occupational mix data for FY 2025.
2. Calculation of the Occupational Mix Adjustment for FY 2025
    For FY 2025, we are proposing to calculate the occupational mix 
adjustment factor using the same methodology that we have used since 
the FY 2012 wage index (76 FR 51582 through 51586) and to apply the 
occupational mix adjustment to 100 percent of the FY 2025 wage index. 
In the FY 2020 IPPS/LTCH PPS final rule (84 FR 42308), we modified our 
methodology with regard to how dollar amounts, hours, and other 
numerical values in the unadjusted and adjusted wage index calculation 
are rounded, in order to ensure consistency in the calculation. 
According to the policy finalized in the FY 2020 IPPS/LTCH PPS final 
rule (84 FR 42308 and 42309), for data that we consider to be ``raw 
data,'' such as the cost report data on

[[Page 36162]]

Worksheets S-3, Parts II and III, and the occupational mix survey data, 
we continue to use these data ``as is'', and not round any of the 
individual line items or fields. However, for any dollar amounts within 
the wage index calculations, including any type of summed wage amount, 
average hourly wages, and the national average hourly wage (both the 
unadjusted and adjusted for occupational mix), we round such dollar 
amounts to 2 decimals. We round any hour amounts within the wage index 
calculations to the nearest whole number. We round any numbers not 
expressed as dollars or hours in the wage index calculations, which 
could include ratios, percentages, or inflation factors, to 5 decimals. 
However, we continue rounding the actual unadjusted and adjusted wage 
indexes to 4 decimals, as we have done historically.
    Similar to the method we use for the calculation of the wage index 
without occupational mix, salaries and hours for a multicampus hospital 
are allotted among the different labor market areas where its campuses 
are located. Table 2 associated with this proposed rule (which is 
available via the internet on the CMS website), which contains the 
proposed FY 2025 occupational mix adjusted wage index, includes 
separate wage data for the campuses of multicampus hospitals. We refer 
readers to section III.C. of the preamble of this proposed rule for a 
chart listing the multicampus hospitals and the FTE percentages used to 
allot their occupational mix data.
    Because the statute requires that the Secretary measure the 
earnings and paid hours of employment by occupational category not less 
than once every 3 years, all hospitals that are subject to payments 
under the IPPS, or any hospital that would be subject to the IPPS if 
not granted a waiver, must complete the occupational mix survey, unless 
the hospital has no associated cost report wage data that are included 
in the proposed FY 2025 wage index. For the proposed FY 2025 wage 
index, we are using the Worksheet S-3, Parts II and III wage data of 
3,075 hospitals, and we used the occupational mix surveys of 2,950 
hospitals for which we also had Worksheet S-3 wage data, which 
represented a ``response'' rate of 96 percent (2,950/3,075). For the 
proposed FY 2025 wage index, we are applying proxy data for 
noncompliant hospitals, new hospitals, or hospitals that submitted 
erroneous or aberrant data in the same manner that we applied proxy 
data for such hospitals in the FY 2012 wage index occupational mix 
adjustment (76 FR 51586). As a result of applying this methodology, the 
proposed FY 2025 occupational mix adjusted national average hourly wage 
is the following:
[GRAPHIC] [TIFF OMITTED] TP02MY24.157

3. Implementation of the Proposed Occupational Mix Adjustment and the 
Proposed FY 2025 Occupational Mix Adjusted Wage Index
    As discussed in section III.E. of the preamble of this proposed 
rule, for FY 2025, we are applying the occupational mix adjustment to 
100 percent of the FY 2025 wage index. We calculated the occupational 
mix adjustment using data from the 2022 occupational mix survey, using 
the methodology described in the FY 2012 IPPS/LTCH PPS final rule (76 
FR 51582-51586).
    Based on the 2022 occupational mix survey data, the proposed FY 
2025 national average hourly wages for each occupational mix nursing 
subcategory as calculated in Step 2 of the occupational mix calculation 
are as follows:
[GRAPHIC] [TIFF OMITTED] TP02MY24.158

    The proposed national average hourly wage for the entire nurse 
category is computed in Step 5 of the occupational mix calculation. 
Hospitals with a nurse category average hourly wage (as calculated in 
Step 4) of greater than the national nurse category average hourly wage 
receive an occupational mix adjustment factor (as calculated in Step 6) 
of less than 1.0. Hospitals with a nurse category average hourly wage 
(as calculated in Step 4) of less than the national nurse category 
average hourly wage receive an occupational mix adjustment factor (as 
calculated in Step 6) of greater than 1.0.
    Based on the 2022 occupational mix survey data, we determined (in 
Step 7 of the occupational mix calculation) the following:

III. Proposed Changes to the Hospital Wage Index for Acute Care 
Hospitals

F. Hospital Redesignations and Reclassifications

    The following sections III.F.1 through III.F.4 discuss revisions to 
the wage index based on hospital redesignations and reclassifications. 
Specifically, hospitals may have their geographic area changed for wage 
index payment by applying for urban to rural reclassification under 
section 1886(d)(8)(E) of the Act (implemented at Sec.  412.103), 
reclassification by the Medicare Geographic Classification Review Board 
(MGCRB) under section 1886(d)(10) of the Act, Lugar status 
redesignations under section 1886(d)(8)(B) of the Act, or a combination 
of the foregoing.
1. Urban to Rural Reclassification Under Section 1886(d)(8)(E) of the 
Act, Implemented at Sec.  412.103
    Under section 1886(d)(8)(E) of the Act, a qualifying prospective 
payment hospital located in an urban area may apply for rural status 
for payment purposes separate from reclassification through the MGCRB. 
Specifically, section 1886(d)(8)(E) of the Act provides that, not later 
than 60 days after the receipt of an application (in a form and manner 
determined by the Secretary) from a subsection (d) hospital that 
satisfies certain criteria, the Secretary shall treat the hospital as 
being located in the rural area (as defined in paragraph (2)(D)) of the 
State in which the hospital is located. We refer readers to the 
regulations at Sec.  412.103 for the general criteria and application 
requirements for a subsection (d) hospital to reclassify from urban to 
rural status in accordance with section 1886(d)(8)(E) of the Act (such 
hospitals are referred to herein as ``Sec.  412.103 hospitals''). The 
FY 2012 IPPS/LTCH PPS final rule (76 FR 51595 through 51596) includes 
our policies regarding the effect of wage data from reclassified or 
redesignated hospitals. We refer readers to the FY 2024 IPPS/LTCH final 
rule (88 FR 58971 through 58977) for a review of our policy finalized 
in the FY 2023 IPPS/LTCH PPS final rule (87 FR 49004) to calculate the 
rural floor with the wage data of urban hospitals reclassifying to 
rural areas under Sec.  412.103, and discussion of our modification to 
the calculation of the rural wage index and its implications for the 
rural floor.
    In the FY 2019 IPPS/LTCH PPS final rule (83 FR 41369 through 
41374), we codified certain policies regarding multicampus hospitals in 
the regulations at Sec. Sec.  412.92, 412.96, 412.103, and 412.108. We 
stated that reclassifications from urban to rural under Sec.  412.103 
apply to the entire hospital (that is, the main campus and its remote 
location(s)). We also stated that a main campus of a hospital cannot 
obtain Sole Community Hospital (SCH), Rural Referral Center (RRC), or 
Medicare Dependent Hospital (MDH) status, or rural reclassification 
under Sec.  412.103, independently or separately from its remote 
location(s), and vice versa. In the FY 2023 IPPS/LTCH PPS final rule 
(87 FR 49012 and 49013), we added Sec.  412.103(a)(8) to clarify that 
for a multicampus hospital, approved rural reclassification status 
applies to the main campus and any remote location located in an urban 
area, including a main campus or any remote location deemed urban under 
section 1886(d)(8)(B) of the Act. If a remote location of a hospital is 
located in a different CBSA than the main campus of the hospital, it is 
CMS' longstanding policy to assign that remote location a wage index 
based on its own geographic area in order to comply with the statutory 
requirement to adjust for geographic differences in hospital wage 
levels (section 1886(d)(3)(E) of the Act). Hospitals are required to 
identify and allocate wages and hours based on FTEs for remote 
locations located in different CBSAs on Worksheet S-2, Part I, Lines 
165 and 166 of form CMS-2552-10. In calculating wage index values, CMS 
identifies the allocated wage data for these remote locations in Table 
2 with a ``B'' in the 3rd position of the CCN. These remote locations 
of hospitals with Sec.  412.103 rural reclassification status in a 
different CBSA are identified in Table 2, and hospitals should evaluate 
potential wage index outcomes for their remote location(s) when 
withdrawing or terminating MGCRB reclassification, or canceling Sec.  
412.103 rural reclassification status.
    We also note that in the FY 2024 IPPS/LTCH PPS final rule (88 FR 
59038 through 59039), we changed the effective date of rural 
reclassification for a hospital qualifying for rural reclassification 
under Sec.  412.103(a)(3) by meeting the criteria for SCH status (other 
than being located in a rural area), and also applying to obtain SCH 
status under Sec.  412.92, where eligibility for SCH classification 
depends on a hospital merger. Specifically, we finalized that in these 
circumstances, and subject to the hospital meeting the requirements set 
forth at Sec.  412.92(b)(2)(vi), the effective date for rural 
reclassification will be the effective date set forth in Sec.  
412.92(b)(2)(vi).
    Finally, we remind hospitals currently located in rural areas 
becoming urban under the proposed adoption of the revised OMB 
delineations in this proposed rule that if they have SCH, MDH, or RRC 
status, they may choose to apply for a Sec.  412.103 urban to rural 
reclassification if qualifying criteria are met in order to maintain 
the SCH, MDH, or RRC status. We advise hospitals to evaluate their 
options and if desired, apply for Sec.  412.103 urban to rural 
reclassification before the beginning of FY 2025, to avoid a lapse in 
SCH, MDH, or RRC status at the beginning of FY 2025 should we finalize 
our proposal to adopt the revised OMB delineations.
a. Proposed Update to Rural Criteria at Sec.  412.103(a)(1)
    Section 1886(d)(8)(E) of the Act describes criteria for hospitals 
located in urban areas to be treated as being located in a rural area 
of their state. The criterion at section 1886(d)(8)(E)(ii)(I) of the 
Act requires that the hospital be located in a rural census tract of a 
metropolitan statistical area (as determined under the most recent 
modification of the Goldsmith Modification, originally published in the 
Federal Register on February 27, 1992 (57 FR 6725)).
    This condition is implemented in the regulation at Sec.  
412.103(a)(1), which currently states: ``the hospital is located in a 
rural census tract of a Metropolitan Statistical Area (MSA) as 
determined under the most recent version of the Goldsmith Modification, 
the Rural-Urban Commuting Area codes, as determined by the Office of 
Rural Health Policy (ORHP) of the Health Resources and Services 
Administration (HRSA), which is available via the ORHP website at: 
http://www.ruralhealth.hrsa.gov or from the U.S. Department of Health 
and Human Services, Health Resources and Services Administration, 
Office of Rural Health Policy, 5600 Fishers Lane, Room 9A-55, 
Rockville, MD 20857.''
    The Goldsmith Modification \136\ was originally designed to 
identify rural census tracts located in Metropolitan counties for 
purposes of grant eligibility unrelated to the hospital IPPS but were 
incorporated by section 1886(d)(8)(E)(ii)(I) of the Act for

[[Page 36164]]

purposes related to the hospital wage index.
---------------------------------------------------------------------------

    \136\ Known as the ``Goldsmith Modification'' for its principal 
developer, Harold F. Goldsmith, this method is described in detail 
in the paper ``Improving the Operational Definition of ``Rural 
Areas'' for Federal Programs'' available at https://www.ruralhealthinfo.org/pdf/improving-the-operational-definition-of-rural-areas.pdf.
---------------------------------------------------------------------------

    The Federal Office of Rural Health Policy (FORHP) (known as ORHP in 
Sec.  412.103) later funded development of Rural-Urban Commuting Area 
(RUCA) codes via the U.S. Department of Agriculture's (USDA) Economic 
Research Service as the latest version of the Goldsmith Modification, 
described in a May 3, 2007 Federal Register notice (72 FR 24589), to 
address limitations of the original Goldsmith Modification. RUCAs, like 
the Goldsmith Modification, are based on a sub-county unit, the census 
tract, permitting a finer delineation of what constitutes rural areas 
inside Metropolitan areas (72 FR 24590). In that notice, HRSA stated it 
believes that the use of RUCAs allows more accurate targeting of 
resources intended for the rural population to determine programmatic 
eligibility for rural areas inside of Metropolitan counties. Using data 
from the Census Bureau, every census tract in the United States is 
assigned a RUCA code. In the May 3, 2007 Federal Register, HRSA stated 
that ORHP considers all census tracts with RUCA codes 4-10 to be rural, 
plus an additional 132 large area census tracts with RUCA codes 2 or 3 
(72 FR 24591). They also stated that ORHP will continue to seek 
refinements in the use of RUCAs.
    FORHP has since published a revised definition of eligibility for 
rural health grants for FY 2022 in a January, 12, 2021 Federal Register 
Notice (86 FR 2418 through 2420). Specifically, FORHP added 
Metropolitan Statistical Area (MSA) counties that contain no Urbanized 
Area (UA) \137\ to the areas eligible for the rural health grant 
programs. FORHP did not remove any areas from the rural definition in 
the FY 2022 Federal Register Notice.
---------------------------------------------------------------------------

    \137\ UAs are defined by the Census Bureau as densely settled 
areas with a total population of at least 50,000 people (86 FR 
2418).
---------------------------------------------------------------------------

    It has come to our attention that our current regulation text at 
Sec.  412.103(a)(1) does not describe FORHP's expanded definition of a 
``rural area'' from the FY 2022 Federal Register Notice. In addition, 
Sec.  412.103(a)(1) contains a web link that is no longer active and 
requires updating. We believe the current rural definition used by 
FORHP for purposes of the rural health grant program constitutes ``the 
most recent modification of the Goldsmith Modification'' referred to in 
the statute, since the expanded definition of rural constitutes a 
refinement to the use of RUCA codes, which were developed as the latest 
version of the Goldsmith Modification. As stated in the FY 2022 Federal 
Register Notice (86 FR 2420), the expanded criteria reflect FORHP's 
desire to accurately identify areas that are rural in character using a 
data-driven methodology that relies on existing geographic identifiers 
and utilizes standard, national level data sources. We are therefore 
proposing to amend our regulation text at Sec.  412.103(a)(1) to 
provide a reference to the most recent Federal Register notice issued 
by HRSA defining ``rural areas.'' In this way, there will be no need to 
update the Medicare regulations if FORHP develops a further 
modification of the Goldsmith Modification or if the weblink changes. 
FORHP has published the current link in the Federal Register notice (86 
FR 2418-2420) along with the most recent revisions to the current 
complete rural definition, and it is available via the Rural Health 
Grants Eligibility Analyzer at https://data.hrsa.gov/tools/rural-health.
    We are proposing to amend the regulation text at 412.103(a)(1) to 
read: the hospital is located in a rural census tract of a Metropolitan 
Statistical Area (MSA) as determined under the most recent version of 
the Goldsmith Modification, using the Rural-Urban Commuting Area codes 
and additional criteria, as determined by the Federal Office of Rural 
Health Policy (FORHP) of the Health Resources and Services 
Administration (HRSA), which is available at the web link provided in 
the most recent Federal Register notice issued by HRSA defining rural 
areas.
b. Proposed Policy for Canceling Sec.  412.103 Reclassifications of 
Terminated Providers
    In the FY 2016 IPPS/LTCH PPS final rule (80 FR 49499 through 
49500), CMS discussed its longstanding policy to terminate the Sec.  
1886(d)(10) MGCRB wage index reclassification status for hospitals with 
terminated CMS certification numbers (CCN). We determined that it would 
be appropriate to terminate the MGCRB reclassification status for these 
hospitals (with a limited exception for certain locations acquired by 
another hospital in a different CBSA), as the hospital may no longer be 
able to make timely and informed decisions regarding reclassification 
statuses.
    At the time, we did not articulate a similar policy for hospitals 
reclassified as rural under Sec.  412.103. While policies regarding 
MGCRB reclassification were adopted for purposes related to the 
hospital wage index, Sec.  412.103 reclassifications may have broader 
implications. At the time the policy to terminate MGCRB 
reclassifications for hospitals with terminated CCNs was implemented, 
Sec.  412.103 reclassifications were less common, and generally had 
negligible effects on State rural wage index values. Prior to FY 2024, 
as a result of various wage index value hold-harmless policies, 
discussed in detail in the FY 2024 IPPS/LTCH PPS final rule (88 FR 
58973-58974), Sec.  412.103 hospital data rarely affected a state's 
final rural wage index value. Under the current policy first 
implemented in FY 2024, however, Sec.  412.103 hospital data is only 
excluded from the rural wage index when indicated by the hold harmless 
provision at section 1886(d)(8)(C)(ii) of the Act. Hospitals 
reclassified under Sec.  412.103 now impact the rural wage index value 
of most states. We refer readers to the FY 2024 IPPS/LTCH final rule 
(88 FR 58973 through 58977) for discussion on how CMS finalized the 
current policy to include the wage index data for Sec.  412.103 
hospitals in more iterations of the rural wage index calculation. 
Furthermore, following the policy implemented in the April 21, 2016 
interim final rule with comment period (IFC) (81 FR 23428 through 
23438), which allowed hospitals to maintain dual Sec.  412.103 and 
MGCRB reclassification status, the number of rural reclassifications 
has grown significantly. We now believe it is appropriate to propose a 
policy regarding terminated or ``tied-out'' hospitals, effective for FY 
2025, to address our concerns regarding the impacts these hospitals 
would have on rural wage index values. Therefore, we are proposing that 
Sec.  412.103 reclassifications will be considered cancelled for the 
purposes of calculating area wage index for any hospital with a CCN 
listed as terminated or ``tied-out'' as of the date that the hospital 
ceased to operate with an active CCN. We propose to obtain and review 
the best available CCN termination status lists as of the Sec.  
412.103(b)(6) ``lock-in'' date (60 days after the proposed rule for the 
FY is displayed in the Federal Register). The lock-in date is used to 
determine whether a hospital has been approved for Sec.  412.103 
reclassification in time for that status to be included in the upcoming 
year's wage index development. We believe using this date for 
evaluating CCN terminations would be consistent with the wage index 
development timeline.
    As stated previously, Sec.  412.103 reclassification may have other 
implications for hospital status and payment. Hospitals may obtain 
rural reclassification for several reasons, such as in order to convert 
to a Critical Access Hospital (CAH), or to obtain Sole-Community 
Hospital (SCH) status.

Eligibility requirements for Rural Emergency Hospital (REH) 
qualification under section 1861(kkk)(3) of the Act included a 
reference to reclassification under section 1886(d)(8)(E) (implemented 
by Sec.  412.103). We note that our proposal to consider Sec.  412.103 
reclassifications cancelled for the purposes of calculating area wage 
index for any hospital with a CCN listed as terminated or ``tied-out'' 
is not intended to alter or affect the qualification for such statuses 
or to have other effects unrelated to hospital wage index calculations. 
The rural reclassification status would remain in effect for any period 
that the original PPS hospital remains in operation with an active CCN. 
For REH qualification requirement purposes, this would include the date 
of enactment of the Consolidated Appropriations Act, 2021 (Pub. L. 116-
260), which was December 27, 2020. We believe this policy provides 
consistency and predictability in wage index values.
2. General Policies and Effects of MGCRB Reclassification and Treatment 
of Dual Reclassified Hospitals
    Under section 1886(d)(10) of the Act, the MGCRB considers 
applications by hospitals for geographic reclassification for purposes 
of payment under the IPPS. Hospitals must apply to the MGCRB to 
reclassify not later than 13 months prior to the start of the fiscal 
year for which reclassification is sought (usually by September 1). 
Generally, hospitals must be proximate to the labor market area to 
which they are seeking reclassification and must demonstrate 
characteristics similar to hospitals located in that area. The MGCRB 
issues its decisions by the end of February for reclassifications that 
become effective for the following fiscal year (beginning October 1). 
The regulations applicable to reclassifications by the MGCRB are 
located in Sec. Sec.  412.230 through 412.280. (We refer readers to a 
discussion in the FY 2002 IPPS final rule (66 FR 39874 and 39875) 
regarding how the MGCRB defines mileage for purposes of the proximity 
requirements.) The general policies for reclassifications and 
redesignations and the policies for the effects of hospitals' 
reclassifications and redesignations on the wage index are discussed in 
the FY 2012 IPPS/LTCH PPS final rule for the FY 2012 final wage index 
(76 FR 51595 and 51596).
    In addition, in the FY 2012 IPPS/LTCH PPS final rule, we discussed 
the effects on the wage index of urban hospitals reclassifying to rural 
areas under Sec.  412.103. In the FY 2020 IPPS/LTCH PPS final rule (84 
FR 42332 through 42336), we finalized a policy to exclude the wage data 
of urban hospitals reclassifying to rural areas under Sec.  412.103 
from the calculation of the rural floor, but we reverted to the pre-FY 
2020 policy in the FY 2023 IPPS/LTCH PPS final rule (87 FR 49002 
through 49004). Hospitals that are geographically located in States 
without any rural areas are ineligible to apply for rural 
reclassification in accordance with the provisions of Sec.  412.103.
    On April 21, 2016, we published an interim final rule with comment 
period (IFC) in the Federal Register (81 FR 23428 through 23438) that 
included provisions amending our regulations to allow hospitals 
nationwide to have simultaneous Sec.  412.103 and MGCRB 
reclassifications. For reclassifications effective beginning FY 2018, a 
hospital may acquire rural status under Sec.  412.103 and subsequently 
apply for a reclassification under the MGCRB using distance and average 
hourly wage criteria designated for rural hospitals. In addition, we 
provided that a hospital that has an active MGCRB reclassification and 
is then approved for redesignation under Sec.  412.103 will not lose 
its MGCRB reclassification; such a hospital receives a reclassified 
urban wage index during the years of its active MGCRB reclassification 
and is still considered rural under section 1886(d) of the Act for 
other purposes.
    We discussed that when there is both a Sec.  412.103 redesignation 
and an MGCRB reclassification, the MGCRB reclassification controls for 
wage index calculation and payment purposes. Prior to FY 2024, we 
excluded hospitals with Sec.  412.103 redesignations from the 
calculation of the reclassified rural wage index if they also have an 
active MGCRB reclassification to another area. That is, if an 
application for urban reclassification through the MGCRB is approved 
and is not withdrawn or terminated by the hospital within the 
established timelines, we consider the hospital's geographic CBSA and 
the urban CBSA to which the hospital is reclassified under the MGCRB 
for the wage index calculation. We refer readers to the April 21, 2016 
IFC (81 FR 23428 through 23438) and the FY 2017 IPPS/LTCH PPS final 
rule (81 FR 56922 through 56930), in which we finalized the April 21, 
2016 IFC, for a full discussion of the effect of simultaneous 
reclassifications under both the Sec.  412.103 and the MGCRB processes 
on wage index calculations. For FY 2024 and subsequent years, we refer 
readers to section III.G.1 of the preamble of the FY 2024 IPPS/LTCH PPS 
final rule for discussion of our proposal to include hospitals with a 
Sec.  412.103 redesignation that also have an active MGCRB 
reclassification to another area in the calculation of the reclassified 
rural wage index (88 FR 58971 through 58977).
a. Proposed Revision To Allow Sec.  412.103 Hospitals To Use Geographic 
Area or Rural Area for Reclassification
    On May 10, 2021, we published an interim final rule with comment 
period (IFC) in the Federal Register (86 FR 24735 through 24739) that 
included provisions amending our regulations to allow hospitals with a 
rural redesignation to reclassify through the MGCRB using the rural 
reclassified area as the geographic area in which the hospital is 
located. We revised our regulation so that the redesignated rural area, 
and not the hospital's geographic urban area, is considered the area a 
Sec.  412.103 hospital is located in for purposes of meeting MGCRB 
reclassification criteria, including the average hourly wage 
comparisons required by Sec.  412.230(a)(5)(i) and (d)(1)(iii)(C). 
Similarly, we revised the regulations to consider the redesignated 
rural area, and not the geographic urban area, as the area a Sec.  
412.103 hospital is located in for purposes of applying the prohibition 
at Sec.  412.230(a)(5)(i) on reclassifying to an area with a pre-
reclassified average hourly wage lower than the pre-reclassified 
average hourly wage for the area in which the hospital is located. 
Effective for reclassification applications due to the MGCRB for 
reclassification beginning in FY 2023, a Sec.  412.103 hospital could 
apply for a reclassification under the MGCRB using the State's rural 
area as the area in which the hospital is located. We refer readers to 
the May 10, 2021 IFC (86 FR 24735 through 24739) and the FY 2022 IPPS/
LTCH PPS final rule (86 FR 45187 through 45190), in which we finalized 
the May 10, 2021 IFC, for a full discussion of these policies.
    In a comment on the May 10, 2021 IFC (86 FR 24735 through 24739), a 
commenter noted that the IFC states that a hospital reclassified under 
Sec.  412.103 could potentially reclassify to any area with a pre-
reclassified average hourly wage that is higher than the pre-
reclassified average hourly wage for the rural area of the State for 
purposes of the regulation at Sec.  412.230(a)(5)(i). The commenter 
asserted that CMS' use of the word ``could'' in this context seems to 
suggest that CMS would allow the hospital to use either its home 
average hourly wage or the rural average hourly wage for purposes of 
the regulation at Sec.  412.230(a)(5)(i). The commenter suggested that 
CMS allow both comparison options, because the rural average hourly 
wage may occasionally be higher than the hospital's home urban area's 
average hourly wage.

[[Page 36166]]

    In response, we clarified that the commenter's interpretation of 
our policy is correct. We stated that while the court's decision in 
Bates County Memorial Hospital v. Azar requires CMS to permit hospitals 
to reclassify to any area with a pre-reclassified average hourly wage 
that is higher than the pre-reclassified average hourly wage for the 
rural area of the state, we do not believe that we are required to 
limit hospitals from using their geographic home area for purposes of 
the regulation at Sec.  412.230(a)(5)(i). Therefore, we clarified that 
we would allow hospitals to reclassify to an area with an average 
hourly wage that is higher than the average hourly wage of either the 
hospital's geographic home area or the rural area (86 FR 45189).
    While we clarified our policy in response to the aforementioned 
comment, the regulation text was not similarly clarified to reflect 
this policy inadvertently. We are therefore proposing to revise the 
regulation text at Sec.  412.230(a)(5)(i) to reflect our policy 
clarified in the FY 2022 IPPS/LTCH PPS final rule (86 FR 45189). While 
it has been CMS' policy to allow a Sec.  412.103 hospital to use either 
its geographic area or the rural area of the State for purposes of 
Sec.  412.230(a)(5)(i), we believe that synchronizing the regulation 
text with our policy clarified in the FY 2022 IPPS/LTCH PPS final rule 
(86 FR 45189) is necessary for consistency and to reduce unnecessary
