Medicare Program; FY 2027 Inpatient Psychiatric Facilities 
Prospective Payment System--Rate Update

AGENCY: Centers for Medicare & Medicaid Services (CMS), Department of 
Health and Human Services (HHS).

ACTION: Final rule.

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

SUMMARY: This final rule updates the prospective payment rates, the 
outlier threshold, and the wage index for Medicare inpatient hospital 
services provided by Inpatient Psychiatric Facilities (IPFs), which 
include psychiatric hospitals and excluded psychiatric units of an 
acute care hospital or critical access hospital. This final rule also 
refines the Inpatient Psychiatric Facilities Prospective Payment System 
(IPF PPS) outlier policy. These changes will be effective for IPF 
discharges occurring during the fiscal year beginning October 1, 2026, 
through September 30, 2027. We are also finalizing the implementation 
of a standardized IPF patient assessment instrument, and removing two 
measures used in the Inpatient Psychiatric Facilities Quality Reporting 
Program.

DATES: These regulations are effective October 1, 2026.

I. Executive Summary

A. Purpose

    This final rule updates the prospective payment rates, the outlier 
threshold, and the wage index for Medicare inpatient hospital services 
provided by Inpatient Psychiatric Facilities (IPFs) for discharges 
occurring during fiscal year (FY) 2027 (beginning October 1, 2026, 
through September 30, 2027). This rule also limits an IPF's outlier 
payments to no more than 20 percent of its total IPF PPS payments in a 
year, effective October 1, 2027, and provides for an exemption to that 
limit for IPFs with fewer than 50 stays per year. Lastly, this final 
rule implements a standardized IPF patient assessment instrument and 
removes two quality measures.

B. Summary of the Major Provisions

1. Inpatient Psychiatric Facilities Prospective Payment System (IPF 
PPS)
    For the IPF PPS, we are finalizing our proposals to:
     Establish a 20 percent cap on outlier payments under the 
IPF PPS. As discussed in section IV.E.c. of this final rule, we are 
modifying the effective date of this policy and limiting it to IPFs 
with 50 or more stays per year.
     Make technical rate setting updates: The IPF PPS payment 
rates will be adjusted annually for input price inflation, as well as 
statutory and other policy factors.
    This rule updates:
    ++ The IPF PPS Federal per diem base rate from $892.87 to $912.40.
    ++ The IPF PPS Federal per diem base rate for providers who failed 
to report quality data to $894.56.
    ++ The electroconvulsive therapy (ECT) payment per treatment from 
$673.85 to $688.59.
    ++ The ECT payment per treatment for providers who failed to report 
quality data to $675.13.
    ++ The labor-related share from 79.0 percent to 78.9 percent.
    ++ The wage index budget neutrality factor to 0.9989.
    ++ The fixed dollar loss threshold amount from $39,360 to $40,750, 
to maintain estimated outlier payments at 2 percent of total estimated 
aggregate IPF PPS payments.
2. Inpatient Psychiatric Facilities Quality Reporting Program
    For the IPF Quality Reporting Program, we are implementing a 
standardized IPF patient assessment instrument (IPF-PAI), as mandated 
by section 4125(b)(1) of the Consolidated Appropriations Act of 2023 
(CAA, 2023) (Pub. L. 117-328), and removing two measures from the 
program: Alcohol Use Brief Intervention Provided or Offered and Alcohol 
Use Brief Intervention (SUB-2/2a) and Tobacco Use Treatment Provided or 
Offered at Discharge (TOB-3/3a).

II. Background

A. Overview of the Legislative Requirements of the IPF PPS

    Section 124 of the Medicare, Medicaid, and State Children's Health 
Insurance Program Balanced Budget Refinement Act of 1999 (BBRA) (Pub. 
L. 106-113) required the establishment and implementation of an IPF PPS 
in a budget neutral manner. Specifically, section 124 of the BBRA 
mandated that the Secretary of Health and Human Services (the 
Secretary) develop a per diem prospective payment system for inpatient 
hospital services furnished in psychiatric hospitals and excluded 
psychiatric units including an adequate patient classification system 
that reflects the differences in patient resource use and costs among 
psychiatric hospitals and excluded psychiatric units. ``Excluded 
psychiatric unit'' means a psychiatric unit of an acute care hospital 
or of a Critical Access Hospital (CAH), which is excluded from payment 
under the Inpatient Prospective Payment System (IPPS) or CAH payment 
system, respectively. These excluded psychiatric units will be paid 
under the IPF PPS.
    Section 405(g)(2) of the Medicare Prescription Drug, Improvement, 
and Modernization Act of 2003 (MMA) (Pub. L. 108-173) extended the IPF 
PPS to psychiatric distinct part units of CAHs.
    Sections 3401(f) and 10322 of the Patient Protection and Affordable 
Care Act (Pub. L. 111-148) as amended by section 10319(e) of that Act 
and by section 1105(d) of the Health Care and Education Reconciliation 
Act of 2010 (Pub. L. 111-152) (hereafter referred to jointly as ``the 
Affordable Care Act'') added subsection (s) to section 1886 of the 
Social Security Act (the Act).
    Section 1886(s)(1) of the Act titled ``Reference to Establishment 
and Implementation of System,'' refers to section 124 of the BBRA, 
which relates to the establishment of the IPF PPS.
    Section 1886(s)(2)(A)(i) of the Act requires the application of the 
productivity adjustment described in section 1886(b)(3)(B)(xi)(II) of 
the Act to the IPF PPS for the rate year (RY) beginning in 2012 (that 
is, a RY that coincides with a FY) and each subsequent RY.
    Section 1886(s)(2)(A)(ii) of the Act required the application of an 
``other adjustment'' that reduced any update to an IPF PPS base rate by 
a percentage point amount specified in section 1886(s)(3) of the Act 
for the RY beginning in 2010 through the RY beginning in 2019. As noted 
in the FY 2020 IPF PPS final rule (84 FR 38424), for the RY beginning 
in 2019, section 1886(s)(3)(E) of the Act required that the other 
adjustment reduction be equal to 0.75 percentage point; that was the 
final year the statute required the application of this adjustment. 
Because FY 2021 was a RY beginning in 2020, FY 2021 was the first year 
that section 1886(s)(2)(A)(ii) of the Act did not apply since its 
enactment.
    Sections 1886(s)(4)(A) through (D) of the Act require that for RY 
2014 and each subsequent RY, IPFs that fail to report required quality 
data with respect to such a RY will have their annual update to a 
standard Federal rate for discharges reduced by 2.0 percentage points. 
This may result in an annual update being less than 0.0 for a RY, and 
may result in payment rates for the upcoming RY being less than such 
payment rates for the preceding RY. Any reduction for failure to report 
required quality data will apply only to the RY involved, and the 
Secretary will not consider such reduction in computing the payment 
amount for a subsequent RY. Additional information about the specifics 
of the current IPF Quality Reporting Program is available in the FY 
2020 IPF PPS final rule (84 FR 38459 through 38468).
    Section 4125 of the Consolidated Appropriations Act, 2023 (CAA, 
2023) (Pub. L. 117-328), which amended section 1886(s) of the Act, 
requires CMS to revise the Medicare prospective payment system for 
psychiatric hospitals and psychiatric units. Specifically, section 
4125(a) of the CAA, 2023 added section 1886(s)(5)(A) of the Act to 
require the Secretary to collect data and information, as the Secretary 
determines appropriate, to revise payments under the IPF PPS. CMS 
discussed this data collection in the FY 2024 IPF PPS final rule (88 FR 
51054), as CMS was required to begin collecting this data and 
information not later than October 1, 2023. As discussed in that rule, 
the agency has already been collecting data and information consistent 
with the types set forth in the CAA, 2023 as part of our extensive and 
years-long analyses and consideration of potential payment system 
refinements. We refer readers to the FY 2024 IPF PPS final rule (88 FR 
51095 through 51098) where we discussed existing data collection and 
requested information to inform future IPF PPS revisions.
    In addition, section 1886(s)(5)(D) of the Act, as added by section 
4125(a) of the CAA, 2023 required that the Secretary implement 
revisions to the methodology for determining the payment rates under 
the IPF PPS for psychiatric hospitals and psychiatric units, effective 
for RY 2025 (FY 2025). Section 1886(s)(5)(D) of the Act provided that 
these revisions may be based on a review of the data and information 
collected under section 1886(s)(5)(A) of the Act. For a detailed 
discussion on the revisions implemented for FY 2025, we refer readers 
to the FY 2025 IPF PPS final rule (89 FR 64590 through 64636).
    Section 4125(b) of the CAA, 2023 amended section 1886(s)(4) of the 
Act by inserting a new subparagraph (E) and redesignating the existing 
subparagraph (E) as subparagraph (F) which requires IPFs participating 
in the IPF Quality Reporting Program to collect and submit to the 
Secretary standardized patient assessment data, using a standardized 
patient assessment instrument, for RY 2028 (FY 2028) and each 
subsequent rate year. IPFs must submit such data with respect to at 
least the admission and discharge of an individual, or more frequently 
as the Secretary determines appropriate. For IPFs to meet this new data 
collection and reporting requirement for RY 2028 and each subsequent 
rate year, the Secretary must implement a standardized patient 
assessment instrument that collects data with respect to the following 
categories: functional status; cognitive function and mental status; 
special services, treatments, and interventions; medical conditions and 
comorbidities; impairments; and other categories as determined 
appropriate by the Secretary. This patient assessment instrument must 
enable comparison of such patient assessment data that IPFs submit 
across all such IPFs to which such data are applicable.
    Section 4125(b) of the CAA, 2023 further amended section 1886(s) of 
the Act by adding a new subparagraph (6) that requires the Secretary to 
implement revisions to the methodology for determining the payment 
rates for psychiatric hospitals and psychiatric units (that is, payment 
rates under the IPF PPS), effective for RY 2031 (FY 2031), as the 
Secretary determines to be appropriate, to take into account the 
patient assessment data described in paragraph (4)(E)(ii).
    To implement and periodically update the IPF PPS, we have published 
various proposed and final rules and notices in the Federal Register. 
For more information regarding these documents, we refer readers to the 
CMS website at https://www.cms.gov/Medicare/Medicare-Fee-for-Service-Payment/InpatientPsychFacilPPS/index.html?redirect=/InpatientPsychFacilPPS/.

B. Overview of the IPF PPS

    We issued the rate year (RY) 2005 IPF PPS final rule that appeared 
in the

[[Page 48516]]

November 15, 2004 Federal Register (69 FR 66922). The RY 2005 IPF PPS 
final rule established the IPF PPS, as required by section 124 of the 
BBRA and codified at 42 CFR part 412, subpart N. The RY 2005 IPF PPS 
final rule set forth the Federal per diem base rate for the 
implementation year (the 18-month period from January 1, 2005, through 
June 30, 2006) and provided payment for the inpatient operating and 
capital costs to IPFs for covered psychiatric services they furnish 
(that is, routine, ancillary, and capital costs, but not costs of 
approved educational activities, bad debts, and other services or items 
that are outside the scope of the IPF PPS). Covered psychiatric 
services include services for which benefits are provided under the 
fee-for-service Part A (Hospital Insurance Program) of the Medicare 
program.
    The IPF PPS established the Federal per diem base rate for each 
patient day in an IPF derived from the national average daily routine 
operating, ancillary, and capital costs in IPFs in FY 2002. The average 
per diem cost was updated to the midpoint of the first year under the 
IPF PPS, standardized to account for the overall positive effects of 
the IPF PPS payment adjustments, and adjusted for budget neutrality.
    The Federal per diem payment under the IPF PPS is comprised of the 
Federal per diem base rate described previously and certain patient- 
and facility-level payment adjustments for characteristics that were 
found in the regression analysis to be associated with statistically 
significant per diem cost differences, with statistical significance 
defined as p less than 0.05. A complete discussion of the regression 
analysis that established the IPF PPS adjustment factors can be found 
in the RY 2005 IPF PPS final rule (69 FR 66933 through 66936).
    The patient-level adjustments include age, Diagnosis-Related Group 
(DRG) assignment, and comorbidities, as well as adjustments to reflect 
higher per diem costs at the beginning of a patient's IPF stay and 
lower costs for later days of the stay. Facility-level adjustments 
include adjustments for the IPF's wage index, rural location, teaching 
status, a cost-of-living adjustment for IPFs located in Alaska and 
Hawaii, and an adjustment for the presence of a qualifying emergency 
department (ED).
    The IPF PPS provides additional payment policies for outlier cases, 
interrupted stays, and a per-treatment payment for patients who undergo 
ECT. During the IPF PPS mandatory 3-year transition period, stop-loss 
payments were also provided; however, since the transition ended as of 
January 1, 2008, these payments are no longer available.

C. Annual Requirements for Updating the IPF PPS

    Section 124 of the BBRA did not specify an annual rate update 
strategy for the IPF PPS and was broadly written to give the Secretary 
discretion in establishing an update methodology. Therefore, in the RY 
2005 IPF PPS final rule, we implemented the IPF PPS using the following 
update strategy:
     Calculate the final Federal per diem base rate to be 
budget neutral for the 18-month period of January 1, 2005, through June 
30, 2006.
     Use a July 1 through June 30 annual update cycle.
     Allow the IPF PPS first update to be effective for 
discharges on or after July 1, 2006, through June 30, 2007.
    The RY 2005 final rule (69 FR 66922) implemented the IPF PPS. In 
developing the IPF PPS, and to ensure that the IPF PPS can account 
adequately for each IPF's case-mix, we performed an extensive 
regression analysis of the relationship between the per diem costs and 
certain patient and facility characteristics to determine those 
characteristics associated with statistically significant cost 
differences on a per diem basis. That regression analysis is described 
in detail in our RY 2004 IPF proposed rule (68 FR 66923; 66928 through 
66933) and our RY 2005 IPF final rule (69 FR 66933 through 66960). For 
characteristics with statistically significant cost differences, we 
used the regression coefficients of those variables to determine the 
size of the corresponding payment adjustments.
    In the RY 2005 IPF final rule, we explained the reasons for 
delaying an update to the adjustment factors, derived from the 
regression analysis, including waiting until we have IPF PPS data that 
yields as much information as possible regarding the patient-level 
characteristics of the population that each IPF serves. We indicated 
that we did not intend to update the regression analysis and the 
patient-level and facility-level adjustments until we complete that 
analysis. Until that analysis is complete, we stated our intention to 
publish a notice in the Federal Register each spring to update the IPF 
PPS (69 FR 66966).
    We issued a final rule which appeared in the May 6, 2011 Federal 
Register titled, ``Inpatient Psychiatric Facilities Prospective Payment 
System--Update for Rate Year Beginning July 1, 2011 (RY 2012)'' (76 FR 
26432), which changed the payment rate update period to a RY that 
coincides with a FY update. Therefore, final rules are now published in 
the Federal Register in the summer to be effective on October 1st of 
each year. When proposing changes in IPF payment policy, a proposed 
rule is issued in the spring, and the final rule in the summer to be 
effective on October 1st. For a detailed list of updates to the IPF 
PPS, we refer readers to our regulations at 42 CFR 412.428. Beginning 
October 1, 2012, we finalized that we would refer to the 12-month 
period from October 1 through September 30 as a ``fiscal year'' (FY) 
rather than a RY (76 FR 26435). Therefore, in this final rule we refer 
to rules that took effect after RY 2012 by the FY, rather than the RY, 
in which they took effect.
    The most recent IPF PPS annual update, the FY 2026 IPF PPS final 
rule (90 FR 37628), appeared in the Federal Register on August 5, 2025. 
The FY 2026 IPF PPS final rule revised the payment adjustment factors 
for teaching status and for IPFs located in rural areas in accordance 
with section 1886(s)(5)(D)(i) of the Act. That final rule also updated 
the IPF PPS Federal per diem base rates that were published in the FY 
2025 IPF PPS final rule (89 FR 64582). In revising the IPF PPS 
adjustment factors, we performed an extensive regression analysis of 
the relationship between the per diem costs and facility 
characteristics to determine those characteristics associated with 
statistically significant cost differences on a per diem basis. That 
regression analysis is described in detail in our FY 2026 IPF PPS 
proposed rule (90 FR 18503 through 18507) and our FY 2026 IPF PPS final 
rule (90 FR 37639 through 37644).
    As required by section 1886(s)(5)(D)(iii) of the Act, we finalized 
a refinement standardization factor for the FY 2026 IPF PPS payment 
rates to maintain budget neutrality for FY 2026. The application of the 
FY 2026 standardization factor is described in detail in our FY 2026 
IPF PPS proposed rule (90 FR 18513 and18514) and our FY 2026 IPF PPS 
final rule (90 FR 37652 and 37653). For FY 2027, we did not propose a 
refinement standardization factor.

III. Analysis of and Responses to the Public Comments

    We received 176 public comments that pertain to proposed IPF PPS 
payment policies, requests for information, and the proposed updates to 
the IPFQR Program. Comments were from inpatient psychiatric facilities, 
health systems, national and state level providers and patient advocacy 
organizations, health information

[[Page 48517]]

technology providers, and individuals. We reviewed each comment and 
grouped related comments, after which we placed them in categories 
based on subject matter or section(s) of the regulation affected. 
Summaries of the public comments received and our responses to those 
comments are provided in the appropriate sections in the preamble of 
this final rule.
    In addition, we received a few comments that were out of the scope 
of the FY 2027 IPF PPS proposed rule. We appreciate these comments but 
note that, because they fall outside the scope of this rulemaking, we 
do not address them in this rule. We may consider these comments as we 
continue to develop policies for future rulemaking, as applicable.

IV. Provisions of the FY 2027 IPF PPS Final Rule and Responses to 
Comments

A. FY 2027 Market Basket Increase and Productivity Adjustment for the 
IPF PPS

1. Background
    Originally, the input price index used to develop the IPF PPS was 
the Excluded Hospital with Capital market basket. This market basket 
was based on 1997 Medicare cost reports for Medicare-participating 
inpatient rehabilitation facilities (IRFs), IPFs, long-term care 
hospitals (LTCHs), cancer hospitals, and children's hospitals. Although 
``market basket'' technically describes the mix of goods and services 
used in providing health care at a given point in time, this term is 
also commonly used to denote the input price index (that is, cost 
category weights and price proxies) derived from that market basket. 
Accordingly, the term ``market basket,'' as used in this document, 
refers to an input price index.
    Since the IPF PPS inception, the market basket used to update IPF 
PPS payments has been rebased and revised to reflect more recent data 
on IPF cost structures. We last rebased and revised the IPF market 
basket in the FY 2024 IPF PPS rule, where we adopted a 2021-based IPF 
market basket, using Medicare cost report data for both Medicare-
participating freestanding psychiatric hospitals and psychiatric units. 
We refer readers to the FY 2024 IPF PPS final rule for a detailed 
discussion of the 2021-based IPF market basket and its development (88 
FR 51057 through 51081). Prior to the 2021-based IPF market basket, we 
used the 2016-based IPF market basket that was adopted in the FY 2020 
IPF PPS final rule (84 FR 38426 through 38447). References to the 
historical market baskets used to update IPF PPS payments prior to the 
FY 2020 IPF PPS rule are listed in the FY 2016 IPF PPS final rule (80 
FR 46656).
2. FY 2027 IPF Market Basket Update
    For FY 2027 (beginning October 1, 2026, and ending September 30, 
2027), we are updating the IPF PPS payments by a market basket increase 
factor, with a productivity adjustment as required by section 
1886(s)(2)(A)(i) of the Act. Consistent with historical practice, we 
proposed to estimate the market basket update for the IPF PPS based on 
the most recent forecast available at the time of rulemaking. For the 
proposed rule, based on IHS Global Inc.'s (IGI) fourth quarter 2025 
forecast with historical data through the third quarter of 2025, the 
proposed 2021-based IPF market basket increase factor for FY 2027 was 
3.1 percent. IGI is a nationally recognized economic and financial 
forecasting firm with which CMS currently contracts to forecast the 
components of the market baskets and productivity adjustment.\1\
---------------------------------------------------------------------------

    \1\ https://www.spglobal.com/en.
---------------------------------------------------------------------------

    Section 1886(s)(2)(A)(i) of the Act requires that, after 
establishing the increase factor for a FY, the Secretary shall reduce 
such increase factor for FY 2012 and each subsequent FY by the 
productivity adjustment described in section 1886(b)(3)(B)(xi)(II) of 
the Act. Section 1886(b)(3)(B)(xi)(II) of the Act sets forth the 
definition of this productivity adjustment. The statute defines the 
productivity adjustment to be equal to the 10-year moving average of 
changes in annual economy-wide, private nonfarm business multifactor 
productivity (as projected by the Secretary for the 10-year period 
ending with the applicable FY, year, cost reporting period, or other 
annual period) (the ``productivity adjustment''). The United States 
Department of Labor's Bureau of Labor Statistics (BLS) publishes the 
official measures of productivity for the U.S. economy. The 
productivity measure referenced in section 1886(b)(3)(B)(xi)(II) of the 
Act is published by BLS as private nonfarm business total factor 
productivity ((TFP) previously referred to as multifactor 
productivity).\2\ We refer readers to www.bls.gov/productivity for the 
BLS historical published TFP data. A complete description of IGI's TFP 
projection methodology is available on the CMS website at https://www.cms.gov/data-research/statistics-trends-and-reports/medicare-program-rates-statistics/market-basket-research-and-information.
---------------------------------------------------------------------------

    \2\ https://www.bls.gov/productivity/notices/2021/mfp-to-tfp-term-change.htm.
---------------------------------------------------------------------------

    Section 1886(s)(2)(A)(i) of the Act requires the application of the 
productivity adjustment described in section 1886(b)(3)(B)(xi)(II) of 
the Act to the IPF PPS for the RY beginning in 2012 (a RY that 
coincides with a FY) and each subsequent RY. For the FY 2027 IPF PPS 
proposed rule, based on IGI's fourth quarter 2025 forecast, the 
proposed productivity adjustment for FY 2027 (the 10-year moving 
average change of TFP for the period ending FY 2027) was projected to 
be 0.8 percentage point. Accordingly, we proposed to reduce the 
proposed 3.1 percent IPF market basket increase by the proposed 0.8 
percentage point productivity adjustment, as mandated by the Act. This 
resulted in a proposed FY 2027 IPF PPS payment rate update of 2.3 
percent (3.1 percent-0.8 percentage point = 2.3 percent). We also 
proposed that if more recent data became available, we would use such 
data, if appropriate, to determine the FY 2027 IPF market basket 
increase and productivity adjustment for the final rule.
    We solicited comments on the proposed IPF market basket increase 
and productivity adjustment for FY 2027. The following is a summary of 
the comments we received and our responses.
    Comment: Several commenters expressed appreciation for the FY 2027 
IPF payment update; however, many commenters stated that the proposed 
payment update is inadequate to address the current cost pressures IPFs 
are facing, and is below current inflation data (as measured by the 
Consumer Price Index (CPI)). Commenters noted that IPFs continue to 
face significant and sustained cost pressures, including rising labor 
costs driven by behavioral health workforce shortages, increased 
reliance on contract staffing, escalating pharmaceutical and supply 
costs, and growing administrative burdens associated with prior 
authorization. A commenter cited American Hospital Association data 
showing total hospital expenses, drug costs, and supply costs increased 
by more than the proposed update. Multiple commenters noted that MedPAC 
had reported negative Medicare margins for IPFs over the 2016 through 
2021 time period.
    Commenters urged CMS to use the most current available data when 
finalizing the FY 2027 market basket update and to consider all 
available policy options to ensure the final update more accurately 
reflects the cost of furnishing inpatient psychiatric care.
    Response: We appreciate the commenters' concerns regarding cost 
pressures facing IPFs and the proposed FY 2027 market basket update.

    As stated in the FY 2024 IPF final rule (88 FR 541057), FY 2025 IPF 
final rule (89 FR 64586), and the FY 2026 IPF final rule (90 FR 37632), 
the 2021-based IPF market basket is a fixed-weight, Laspeyres-type 
index that measures price changes over time. Any changes in the 
quantity or mix of goods and services (that is, intensity) purchased 
over time relative to the base period are not measured. Since the 
inception of the IPF PPS, the IPF payment rates (with the exception of 
statutorily-mandated updates) have been updated by a projection of the 
market basket's percentage increase, consistent with other CMS PPS 
updates (including IPPS, SNF, and HHA). Additionally, the market basket 
updates appropriately differ from other payment updates (such as the 
projected increase in the average per capita payments to Medicare 
Advantage organizations) that are not consistent in concept with the 
statutory requirement as they would reflect anticipated volume and 
intensity of services.\3\ Likewise, the market basket updates may 
differ from other overall inflation indexes (such as the CPI) as it 
measures different mixes of products and services.

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

    As is our general practice, we proposed in the FY 2027 IPF proposed 
rule that if more recent data became available, we would use such data, 
if appropriate, to derive the final FY 2027 IPF market basket update 
for the final rule. The projection of the 2021-based IPF market basket 
is based on the most recent forecast from IHS Global Inc., a nationally 
recognized economic and financial forecasting firm with which CMS 
contracts to forecast the price proxies of the market baskets. We also 
note that when developing its forecast for labor prices, IHS Global 
Inc. considers overall labor market conditions (including rise in 
contract labor employment due to tight labor market conditions) as well 
as trends in contract labor wages, which both have an impact on wage 
pressures for workers employed directly by the hospital. For this final 
rule, based on IHS Global Inc.'s second quarter 2026 forecast with 
historical data through the first quarter of 2026, the projected 2021-
based IPF market basket increase factor for FY 2027 is 3.2 percent, 
which is 0.1 percentage point higher than the projected FY 2027 market 
basket increase factor in the proposed rule.
    Comment: Several commenters conveyed concerns regarding the ongoing 
application of the productivity adjustment to IPFs. Several commenters 
stated that they believe the productivity adjustment to be 
inappropriate and unrealistic when applied to inpatient psychiatric 
providers. Commenters stated that the productivity adjustment is based 
on economy-wide private nonfarm business total factor productivity 
(TFP), which does not reflect the operational realities of IPFs. They 
explain that inpatient psychiatric care is highly labor-intensive, 
relies on direct human interaction, and is subject to strict staffing, 
safety, and regulatory requirements that leave little opportunity to 
achieve productivity gains comparable to those in the broader economy. 
A couple of commenters further noted that CMS's Office of the Actuary 
(OACT) has found that hospital sector productivity growth ranges from 
0.2 percent to 0.5 percent annually, roughly half the rate used in the 
proposed adjustment, making the 0.8 percentage point offset 
inconsistent with CMS's own analytical findings.\4\ A few other 
commenters specifically urged CMS to invoke its ``special exceptions 
and adjustments'' authority to waive or reduce the productivity 
adjustment for FY 2027 and called on CMS to work with the Congress to 
modify the statutory framework to base the productivity adjustment on 
hospital sector productivity rather than private non-farm business 
productivity.

Presentation of Two Methodologies Using Data through 2019.''
---------------------------------------------------------------------------

    A commenter also stated that they find it especially troubling that 
the productivity adjustment appears to be applied only when it reduces 
Medicare payments.
    Response: Section 1886(s)(2)(A)(i) of the Act requires the 
application of the productivity adjustment described in section 
1886(b)(3)(B)(xi)(II) of the Act to the IPF PPS for the rate year (RY) 
beginning in 2012 (that is, a RY that coincides with a FY) and each 
subsequent RY. Therefore, as required by statute, the FY 2027 
productivity adjustment is derived based on the 10-year moving average 
growth in economy-wide private nonfarm business total factor 
productivity for the period ending FY 2027. We recognize the concerns 
of the commenters regarding the appropriateness of the productivity 
adjustment; however, section 1886(s)(2)(A)(i) of the Act requires us to 
apply the specific productivity adjustment described here.
    We have always made available on the CMS website the general method 
for calculating the productivity adjustment. This includes providing a 
link to the most recent BLS historical TFP data, which allows 
interested parties to obtain historical TFP annual index levels for 
1987 through 2025. We also provide the IGI projection model (https://www.cms.gov/research-statistics-data-and-systems/statistics-trends-and-reports/medicareprogramratesstats/downloads/tfp_methodology.pdf), which 
is used to derive annual TFP growth rates for 2026 and 2027. The annual 
index level derived from this method is then interpolated to quarterly 
levels, and the FY 2027 productivity adjustment is equal to the percent 
change in the 40-quarter moving average projected level for the period 
ending September 30, 2027, relative to the 40-quarter moving average 
projected level for the period ending September 30, 2026. We believe 
our methodology for the productivity adjustment is consistent with 
section 1886(b)(3)(B)(xi)(II) of the Act which states that the 
productivity adjustment is equal to the 10-year moving average of 
changes in annual economy-wide private nonfarm business multi-factor 
productivity (as projected by the Secretary for the 10-year period 
ending with the applicable fiscal year, year, cost reporting period, or 
other annual period).
    At the time of this final rule, the 2027 productivity adjustment 
reflects BLS historical TFP data through 2025 (released on March 19, 
2026) and IGI's forecasted TFP growth for 2026 and 2027. The average 
annual growth rate of historical TFP published by BLS for 2018 through 
2025 is currently 1.0 percent and IGI is projecting average TFP growth 
of about 0.7 percent for 2026 and 2027 based on IGI's second-quarter 
2026 forecast. Combining the historical and projected TFP data over the 
entire 10-year time period and interpolating into quarterly index 
levels results in a 10-year moving average growth rate of TFP of 0.9 
percent for FY 2027. The productivity adjustment (based on the 10-year 
period ending with FY 2027) for the FY 2027 final rule is 0.1 
percentage point higher than the FY 2027 IPF proposed rule mainly due 
to the incorporation of updated BLS historical data.
    In response to commenters' concerns about the productivity 
adjustment only being applied if it reduces the payment update, and as 
noted in the FY 2026 IPF final rule (90 FR 37628), we note that the 
productivity adjustment was established under the Affordable Care Act 
with a specific policy intent to encourage efficiency improvements in 
healthcare delivery by linking Medicare

[[Page 48519]]

payment updates to economy-wide productivity gains. The statutory 
language in section 1886(b)(3)(B)(xi)(II) of the Act requires that the 
Secretary reduce (not increase) the market basket percentage increase 
by changes in economy-wide productivity; therefore, only positive 
productivity adjustments are applied.
    Comment: Several commenters have noted concerns about CMS's 
estimation of the IPF market basket updates since the COVID-19 
pandemic, stating that it has resulted in several consecutive years of 
underpayments to IPF health care providers since the COVID-19 pandemic. 
A few commenters cited CMS Office of the Actuary data showing that 
market basket forecasts used in the final rules for FY 2021 through FY 
2024 understated actual IPF inflation by a cumulative 4.2 percentage 
points. They argue that these understatements are now permanently 
embedded in the IPF PPS base rate and continue to compound year over 
year, widening the gap between Medicare payment rates and the actual 
cost of care. Several commenters urged CMS to adopt a one-time forecast 
error adjustment to correct for this cumulative underestimation, and 
for it to be added to the to the currently proposed 2.3 percent 
increase for FY 2027. A couple of commenters noted that CMS's reliance 
on lagged cost data has caused payment updates to persistently trail 
actual cost growth, and urged CMS to use the most current available 
data, and to work with the Congress where necessary, to ensure the FY 
2027 update more accurately reflects the inflationary environment IPFs 
are operating in.
    Response: The IPF market basket updates are set prospectively, 
which means that the update relies on a mix of both historical data for 
part of the period for which the update is calculated and forecasted 
data for the remainder. For instance, the FY 2027 market basket update 
in this final rule reflects historical data through the first quarter 
of CY 2026 and forecasted data for the second quarter of CY 2026 
through the third quarter of CY 2027. While there is no precedent to 
adjust for market basket forecast error in the IPF payment update, a 
forecast error can be calculated by comparing the actual market basket 
increase for a given year less the forecasted market basket increase. 
Due to the uncertainty regarding future price trends, forecast errors 
can be both positive and negative. The forecast error has been both 
positive and negative during past years, and over longer periods of 
time the cumulative forecast hasn't deviated significantly from the 
historical measures. Only considering the forecast error for years when 
the IPF market basket update was lower than the actual market basket 
update does not consider the full experience and impact of the 
cumulative forecast error.
    Final Decision: After consideration of the comments received, we 
are finalizing our proposal to update IPF PPS payment rates using the 
latest available productivity-adjusted market basket increase factor. 
Based on IGI's second quarter 2026 forecast, the 2021-based IPF market 
basket percentage increase for FY 2027 is 3.2 percent and the projected 
FY 2027 productivity adjustment is 0.9 percentage point. Therefore, the 
final FY 2027 IPF market basket update is equal to 2.3 percent (3.2 
percent market basket percentage increase reduced by the 0.9 percentage 
point productivity adjustment).
3. FY 2027 IPF Labor-Related Share
    Due to variations in geographic wage levels and other labor-related 
costs, we believe that payment rates under the IPF PPS should continue 
to be adjusted by a geographic wage index, which will apply to the 
labor-related portion of the Federal per diem base rate (hereafter 
referred to as the ``labor-related share''). The labor-related share is 
determined by identifying the national average proportion of total 
costs that are related to, influenced by, or vary with the local labor 
market. We proposed to continue to classify a cost category as labor-
related if the costs are labor-intensive and vary with the local labor 
market.
    Based on our definition of the labor-related share and the cost 
categories in the 2021-based IPF market basket, we proposed to continue 
to include in the labor-related share the sum of the relative 
importance of Wages and Salaries; Employee Benefits; Professional Fees: 
Labor-Related; Administrative and Facilities Support Services; 
Installation, Maintenance, and Repair Services; All Other: Labor-
Related Services; and a portion of the Capital-Related relative 
importance from the 2021-based IPF market basket. For more details 
regarding the methodology for determining specific cost categories for 
inclusion in the labor-related share based on the 2021-based IPF market 
basket, we refer readers to the FY 2024 IPF PPS final rule (88 FR 51078 
through 51081).
    The relative importance reflects the different rates of price 
change for these cost categories between the base year (FY 2021) and FY 
2027. Based on IGI's fourth quarter 2025 forecast of the 2021-based IPF 
market basket, the sum of the FY 2027 relative importance moving 
average of Wages and Salaries; Employee Benefits; Professional Fees: 
Labor-Related; Administrative and Facilities Support Services; 
Installation, Maintenance, and Repair Services; All Other: Labor-
Related Services is 76.0 percent. We proposed, consistent with prior 
rulemaking, that the portion of Capital-Related costs that are 
influenced by the local labor market is 46 percent. Since the relative 
importance for Capital-Related costs is 6.7 percent of the 2021-based 
IPF market basket for FY 2027, we proposed to take 46 percent of 6.7 
percent to determine a labor-related share of Capital-Related costs for 
FY 2027 of 3.1 percent. Therefore, we proposed a total labor-related 
share for FY 2027 of 79.1 percent (the sum of 76.0 percent for the 
labor-related share of operating costs and 3.1 percent for the labor-
related share of Capital-Related costs). We also proposed that if more 
recent data became available, we would use such data, if appropriate, 
to determine the FY 2027 labor-related share for the final rule. For 
more information on the labor-related share and its calculation, we 
refer readers to the FY 2024 IPF PPS final rule (88 FR 51078 through 
51081.
    We solicited comments on the proposed labor-related share for FY 
2027. The following is a summary of the comments we received and our 
responses.
    Comment: A few commenters expressed support for the increase in the 
labor-related share from 79.0 percent to 79.1 percent for FY 2027, 
noting that while CMS estimates a labor-related share of approximately 
79 percent for IPFs, they continue to face workforce challenges 
including shortages of psychiatrists, behavioral health nurses, and 
support personnel that the labor-related share does not adequately 
reflect.
    Response: We appreciate the commenters' support for the FY 2027 IPF 
labor-related share. As described above, we define the labor-related 
share as those expenses that are labor-intensive and vary with, or are 
influenced by, the local labor market. Each year, we calculate a 
revised labor-related share based on the relative importance of labor-
related cost categories in the input price index. For the 2021-based 
IPF market basket, those cost categories are: (1) Wages and Salaries 
(including allocated contract labor costs); (2) Employee Benefits 
(including allocated contract labor costs); (3) Professional Fees: 
Labor-Related; (4) Administrative and Facilities Support Services; (5) 
Installation, Maintenance, and Repair Services; (6) All Other: Labor-
Related Services; and (7) a proportion of capital-

[[Page 48520]]

related expenses. The full methodology for determining the labor-
related share of the 2021-based IPF market basket is detailed in the FY 
2024 IPF PPS Final Rule (88 FR 51078).
    We proposed to use the FY 2027 relative importance values for the 
labor-related cost categories from the 2021-based IPF market basket 
because it accounts for more recent data regarding price pressures and 
cost structure of IPFs. This methodology is consistent with the 
determination of the labor-related share since the implementation of 
the IPF PPS. As stated in the FY 2027 IPF proposed rule, we also 
proposed that if more recent data became available, we would use such 
data, if appropriate, to determine the FY 2027 labor-related share for 
the final rule. Based on IHS Global Inc.'s second quarter 2026 forecast 
with historical data through the first quarter of 2026, the FY 2027 
labor-related share for the final rule is 78.9 percent.
    Final Decision: After consideration of the comments, we are 
finalizing a FY 2027 labor-related share based on the latest available 
data. Based on IGI's second quarter 2026 forecast of the 2021-based IPF 
market basket, the sum of the FY 2027 relative importance moving 
average of Wages and Salaries; Employee Benefits; Professional Fees: 
Labor-Related; Administrative and Facilities Support Services; 
Installation, Maintenance, and Repair Services; All Other: Labor-
Related Services is 75.8 percent. Since the relative importance for 
Capital-Related costs is 6.7 percent of the 2021-based IPF market 
basket for FY 2027, we take 46 percent of 6.7 percent to determine a 
labor-related share of Capital-Related costs for FY 2027 of 3.1 
percent. Therefore, the total labor-related share for FY 2027 is 78.9 
percent (the sum of 75.8 percent for the labor-related share of 
operating costs and 3.1 percent for the labor-related share of Capital-
Related costs).
    Table 1 shows the final FY 2027 labor-related share and the final 
FY 2026 labor-related share using the 2021-based IPF market basket

B. Updates to the IPF PPS Rates for FY Beginning October 1, 2026

    The IPF PPS is based on a standardized Federal per diem base rate 
calculated from the IPF average per diem costs and adjusted for budget 
neutrality in the implementation year. The Federal per diem base rate 
is used as the standard payment per day under the IPF PPS and is 
adjusted by the patient-level and facility-level adjustments that are 
applicable to the IPF stay. A detailed explanation of how we calculated 
the average per diem cost appears in the RY 2005 IPF PPS final rule (69 
FR 66926).
1. Determining the Standardized Budget Neutral Federal per Diem Base 
Rate
    Section 124(a)(1) and (c) of the BBRA requires that we implement 
the IPF PPS in a budget neutral manner. In other words, the amount of 
total payments under the IPF PPS, including any payment adjustments, 
must be projected to be equal to the amount of total payments that 
would have been made if the IPF PPS were not implemented. Therefore, we 
calculated the budget neutrality factor by setting the total estimated 
IPF PPS payments to be equal to the total estimated payments that would 
have been made under the Tax Equity and Fiscal Responsibility Act of 
1982 (TEFRA) (Pub. L. 97-248) methodology had the IPF PPS not been 
implemented. A step-by-step description of the methodology used to 
estimate payments under the TEFRA payment system appears in the RY 2005 
IPF PPS final rule (69 FR 66926).
    Under the IPF PPS methodology, we calculated the final Federal per 
diem base rate to be budget neutral during the IPF PPS implementation 
period (that is, the 18-month period from January 1, 2005, through June 
30, 2006) using a July 1 update cycle. We updated the average cost per 
day to the midpoint of the IPF PPS implementation period (October 1, 
2005), and this amount was used in the payment model to establish the 
budget neutrality adjustment.
    Next, we standardized the IPF PPS Federal per diem base rate to 
account for the overall positive effects of the IPF PPS payment 
adjustment factors by

[[Page 48521]]

dividing total estimated payments under the TEFRA payment system by 
estimated payments under the IPF PPS. The information concerning this 
standardization can be found in the RY 2005 IPF PPS final rule (69 FR 
66932) and the RY 2006 IPF PPS final rule (71 FR 27045). We then 
reduced the standardized Federal per diem base rate to account for the 
outlier policy, the stop loss provision, and anticipated behavioral 
changes. A complete discussion of how we calculated each component of 
the budget neutrality adjustment appears in the RY 2005 IPF PPS final 
rule (69 FR 66932 and 66933) and in the RY 2007 IPF PPS final rule (71 
FR 27044 through 27046). The final standardized budget neutral Federal 
per diem base rate established for cost reporting periods beginning on 
or after January 1, 2005 was calculated to be $575.95.
    The Federal per diem base rate has been updated in accordance with 
applicable statutory requirements and 42 CFR 412.428 through 
publication of annual notices or proposed and final rules. A detailed 
discussion on the standardized budget neutral Federal per diem base 
rate and the ECT payment per treatment appears in the FY 2014 IPF PPS 
update notice (78 FR 46738 through 46740). These documents are 
available on the CMS website at https://www.cms.gov/medicare/payment/prospective-payment-systems/inpatient-psychiatric-facility.
2. Determining the Electroconvulsive Therapy (ECT) Payment per 
Treatment
    In the RY 2005 IPF PPS final rule (69 FR 66951), we analyzed the 
costs of IPF stays that included ECT treatment using the FY 2002 
Medicare Provider and Analysis Review (MedPAR) data based on comments 
we received on the RY 2005 IPF PPS proposed rule. Consistent with the 
comments we received about ECT, our analysis and review indicated that 
cases with ECT treatment are substantially more costly than cases 
without ECT treatment. Based on this analysis, in that final rule we 
finalized an additional payment for each ECT treatment furnished during 
the IPF stay. This ECT payment per treatment is made in addition to the 
per diem and outlier payments under the IPF PPS. To receive the payment 
per ECT treatment, IPFs must indicate on their claims the revenue code 
and procedure code for ECT (Rev Code 901; procedure code 90870) and the 
number of units of ECT, that is, the number of ECT treatments the 
patient received during the IPF stay.
    To establish the ECT per treatment payment, we used the pre-scaled 
and pre-adjusted median cost for procedure code 90870 developed for the 
Hospital Outpatient Prospective Payment System (OPPS), based on 
hospital claims data. We explained in the RY 2005 IPF PPS final rule 
that we used OPPS data because after careful review and analysis of IPF 
claims, we were unable to separate out the cost of a single ECT 
treatment (69 FR 66922). We used the unadjusted hospital claims data 
under the OPPS because we did not want the ECT payment under the IPF 
PPS to be affected by factors that are relevant to OPPS, but not 
specifically applicable to IPFs. The median cost was then standardized 
and adjusted for budget neutrality. We also adjusted the ECT rate for 
wage differences in the same manner that we adjust the per diem rate.
    Most recently, as we explained in the FY 2025 IPF PPS proposed rule 
(89 FR 23146), we analyzed recent data from both the IPF PPS and the 
OPPS. Findings revealed that costs for IPF stays involving ECT were 
significantly more costly than stays without ECT, with cost driven 
primarily by longer stays and higher ancillary expenses. To address 
this, we finalized a new ECT payment calculation based on the pre-
scaled and pre-adjusted CY 2024 OPPS geometric mean cost, adjusted by 
the market basket update and wage index budget neutrality factor. A 
complete discussion of the final FY 2025 ECT payment per treatment can 
be found in the FY 2025 IPF PPS final rule (89 FR 64591 through 64593).
    Since the ECT payment rate was established in the RY 2005 IPF PPS 
rule, it has been updated annually by application of each year's market 
basket, productivity adjustment, and wage index budget neutrality 
factor to the previous year's ECT payment rate (referred to as our 
``standard methodology'' in this section).
3. Update of the Federal per Diem Base Rate and Electroconvulsive 
Therapy Payment per Treatment
    The current (FY 2026) Federal per diem base rate is $892.87 and the 
ECT payment per treatment is $673.85. For the final FY 2027 Federal per 
diem base rate, we applied the final IPF market basket update of 2.3 
percent (that is, the 2021-based IPF market basket percentage increase 
for FY 2027 of 3.2 percent reduced by the productivity adjustment of 
0.9 percentage point), and the final wage index budget neutrality 
factor of 0.9989 (as discussed in section IV.D.1.c. of this final rule) 
to the final FY 2026 Federal per diem base rate of $892.87, yielding a 
final Federal per diem base rate of $912.40 for FY 2027. We applied the 
final IPF market basket update of 2.3 percent and the wage index budget 
neutrality factor of 0.9989 to the final FY 2026 ECT payment per 
treatment of $673.85, yielding a final ECT payment per treatment of 
$688.59 for FY 2027.
    Section 1886(s)(4)(A)(i) of the Act requires that for RY 2014 and 
each subsequent RY, in the case of an IPF that fails to report required 
quality data with respect to such RY, the Secretary will reduce any 
annual update to a standard Federal rate for discharges during the RY 
by 2.0 percentage points. Therefore, we applied a 2.0 percentage point 
reduction to the final annual update to the Federal per diem base rate 
and the final ECT payment per treatment as follows:
     For IPFs that fail to report required data under the IPF 
Quality Reporting Program, we will apply a 0.3 percent payment rate 
update--that is, the final IPF market basket increase for FY 2027 of 
3.2 percent reduced by the final productivity adjustment of 0.9 
percentage point for an update of 2.3 percent, and further reduced by 
2.0 percentage points in accordance with section 1886(s)(4)(A)(i) of 
the Act. We also applied the wage index budget neutrality factor of 
0.9989 to the FY 2026 Federal per diem base rate of $892.87, yielding a 
Federal per diem base rate of $894.56 for FY 2027.
     For IPFs that fail to report required data under the IPF 
Quality Reporting Program, we will apply the 0.3 percent payment rate 
update and the 0.9989 wage index budget neutrality factor to the FY 
2026 ECT payment per treatment of $673.85, yielding an ECT payment per 
treatment of $675.13 for FY 2027.

C. Updates to the IPF PPS Patient-Level Adjustment Factors

1. Overview of the IPF PPS Adjustment Factors
    The IPF PPS payment adjustment factors were originally derived from 
a regression analysis of 100 percent of the FY 2002 MedPAR data file, 
which contained 483,038 cases. For a more detailed description of the 
data file used for this regression analysis, we refer readers to the RY 
2005 IPF PPS final rule (69 FR 66935 and 66936).
    In FY 2025, we implemented revisions to the methodology for 
determining payment rates under the IPF PPS, as required by section 
1886(s)(5)(D) of the Act. We developed the FY 2025 adjustment factors 
based on a regression analysis of IPF cost and claims data. The primary 
sources of this analysis were CY 2019 through 2021 MedPAR files and 
Medicare cost report data (CMS Form 2552-10, OMB No. 0938-0050) from 
the FY 2019 through

[[Page 48522]]

2021 Hospital Cost Report Information System (HCRIS). For a more 
detailed description of the data files used for this regression 
analysis, we refer readers to the FY 2025 IPF PPS final rule (89 FR 
64593 through 64601).
    For FY 2027, we proposed to use the existing regression-derived 
patient-level adjustment factors established for FY 2025. We did not 
propose any changes to the patient-level adjustment factors for FY 
2027; however, we used more recent claims data to simulate payments, to 
finalize the outlier fixed dollar loss threshold amount, and to assess 
the impact of the IPF PPS updates.
2. IPF PPS Patient-Level Adjustments
    The IPF PPS includes payment adjustments for the following patient-
level characteristics: Medicare Severity Diagnosis Related Groups (MS-
DRGs) assignment of the patient's principal diagnosis, selected 
comorbidities, patient age, and the variable per diem adjustments.
a. Update to MS-DRG Assignment
    We believe it is important to maintain for IPFs the same diagnostic 
coding and DRG classification used under the IPPS for providing 
psychiatric care. For this reason, when the IPF PPS was implemented for 
cost reporting periods beginning on or after January 1, 2005, we 
adopted the same diagnostic code set (ICD-9 Clinical Modification (CM)) 
and DRG patient classification system (MS-DRGs) that were utilized at 
the time under the IPPS. In the RY 2009 IPF PPS notice (73 FR 25709), 
we discussed CMS's effort to better recognize resource use and the 
severity of illness among patients. CMS adopted the new MS-DRGs for the 
IPPS in the FY 2008 IPPS final rule with comment period (72 FR 47130). 
In the RY 2009 IPF PPS notice (73 FR 25716), we provided a crosswalk to 
reflect changes that were made under the IPF PPS to adopt the new MS-
DRGs. For a detailed description of the mapping changes from the 
original DRG adjustment categories to the current MS-DRG adjustment 
categories, we refer readers to the RY 2009 IPF PPS notice (73 FR 
25714).
    The IPF PPS includes payment adjustments for designated psychiatric 
DRGs assigned to the claim based on the patient's principal diagnosis. 
The DRG adjustment factors were expressed relative to the most 
frequently reported psychiatric DRG in FY 2002, that is, DRG 430 
(psychoses). The coefficient values and adjustment factors were derived 
from the regression analysis discussed in detail in the RY 2004 IPF 
proposed rule (68 FR 66923; 66928 through 66933) and the RY 2005 IPF 
final rule (69 FR 66933 through 66960). Mapping the DRGs to the MS-DRGs 
resulted in 17 IPF MS-DRGs, instead of the original 15 DRGs, for which 
the IPF PPS provides an adjustment.
    In the FY 2015 IPF PPS final rule (79 FR 45945 through 45947), we 
finalized conversions of the ICD-9-CM-based MS-DRGs to ICD-10-CM/
Procedure Coding System (PCS)-based MS-DRGs, which were implemented on 
October 1, 2015. Further information on the ICD-10-CM/PCS MS-DRG 
conversion project can be found on the CMS ICD-10-CM website at https://www.cms.gov/medicare/coding-billing/icd-10-codes/icd-10-ms-drg-conversion-project.
    In the FY 2025 IPF PPS final rule (89 FR 64602 through 64606), we 
revised the payment adjustments for designated psychiatric DRGs 
assigned to the claim based on the patient's principal diagnosis, 
following our longstanding policy of using the ICD-10-CM/PCS-based MS-
DRG system. In that final rule, we identified 19 DRGs for which the IPF 
PPS adjusts payment. In addition, we implemented a sub-regulatory 
process to adopt routine coding updates that incorporate new or revised 
codes with an April 1 effective date (89 FR 64602 and 64603).
    For FY 2027, we proposed to continue making the existing payment 
adjustments for psychiatric diagnoses that group to one of the existing 
19 IPF MS-DRGs listed in Addendum A. We did not receive any comments on 
this proposal, and we are finalizing it as proposed. Addendum A to this 
final rule is available on our website at https://www.cms.gov/medicare/payment/prospective-payment-systems/inpatient-psychiatric-facility-pps/
tools-and-worksheets. Psychiatric principal diagnoses that do not group 
to one of the 19 designated MS-DRGs would still receive the Federal per 
diem base rate and all other applicable adjustments, but the payment 
would not include an MS-DRG adjustment.
    The diagnoses for each IPF MS-DRG will be updated as of October 1, 
2026, using the final IPPS FY 2027 ICD-10-CM/PCS code sets. The FY 2027 
IPPS/LTCH PPS final rule will include tables of the changes to the ICD-
10-CM/PCS code sets that underlie the final FY 2027 IPF MS-DRGs. Both 
the FY 2027 IPPS/LTCH PPS final rule and the tables of final changes to 
the ICD-10-CM/PCS code sets, which underlie the FY 2027 MS-DRGs, will 
be available on the CMS IPPS website at https://www.cms.gov/medicare/payment/prospective-payment-systems/acute-inpatient-pps.
    Additionally, as discussed in the ICD-10-CM Official Guidelines for 
Coding and Reporting, certain conditions have both an underlying 
etiology and multiple body system manifestations due to the underlying 
etiology. For such conditions, the ICD-10-CM has a coding convention 
that requires the underlying condition be sequenced first, followed by 
the manifestation. Wherever such a combination exists, there is a ``use 
additional code'' note at the etiology code, and a ``code first'' note 
at the manifestation code. These instructional notes indicate the 
proper sequencing order of the codes (etiology followed by 
manifestation). In accordance with the ICD-10-CM Official Guidelines 
for Coding and Reporting, when a primary (psychiatric) diagnosis code 
has a code first note, the provider will follow the instructions in the 
ICD-10-CM Tabular List. The submitted claim goes through the ICD-10 MS-
DRG GROUPER Software, which will identify the principal diagnosis code 
as non-psychiatric and search the secondary codes for a psychiatric 
code to assign a DRG code for adjustment. The software will continue to 
search the secondary codes for those that are appropriate for 
comorbidity adjustment. For more information on the code first policy, 
we refer readers to the RY 2005 IPF PPS final rule (69 FR 66945). We 
also refer readers to sections I.A.13 and I.B.7 of the FY 2020 ICD-10-
CM Coding Guidelines, which is available at https://www.cdc.gov/nchs/data/icd/10cmguidelines-FY2020_final.pdf. In the FY 2015 IPF PPS final 
rule, we provided a code first table for reference that highlights the 
same or similar manifestation codes where the code first instructions 
apply in ICD-10-CM that were present in ICD-10-CM (79 FR 46009).
    As discussed in the FY 2025 IPF PPS final rule (89 FR 64602 and 
64603), we adopted a sub-regulatory approach to handle the coding 
updates, rather than discussing coding updates in the Federal Register 
during regulatory updates prior to implementation. This approach 
mirrors the approach taken by the IPPS, allows for flexibility in the 
ICD-10 code update process for the IPF PPS, and reduces the lead time 
for making routine coding updates to the IPF PPS code first list, 
comorbidities, and ECT coding categories. The final FY 2027 Code First 
table is shown in Addendum B on the CMS website at https://www.cms.gov/medicare/payment/prospective-payment-systems/inpatient-psychiatric-facility-pps/tools-and-worksheets.
b. Payment for Comorbid Conditions
    The intent of the comorbidity adjustments is to recognize the

[[Page 48523]]

increased costs associated with active comorbid conditions by providing 
additional payments for certain existing medical or psychiatric 
conditions that are expensive to treat.
    Comorbidities are specific patient conditions that are secondary to 
the patient's principal diagnosis and that require active treatment 
during the stay. Diagnoses that relate to an earlier episode of care 
and have no bearing on the current hospital stay are excluded and must 
not be reported on IPF claims. Comorbid conditions must exist at the 
time of admission or develop subsequently, and affect the treatment 
received, length of stay (LOS), or both treatment and LOS.
    For each claim, an IPF may receive only one comorbidity adjustment 
within a comorbidity category, but it may receive an adjustment for 
more than one comorbidity category. Current billing instructions for 
discharge claims, on or after October 1, 2015, require IPFs to enter 
the complete ICD-10-CM codes for up to 24 additional diagnoses if they 
co-exist at the time of admission, or develop subsequently and impact 
the treatment provided.
    The IPF PPS comorbidity adjustments were originally determined 
based on the regression analysis using the diagnoses reported by IPFs 
in FY 2002. The principal diagnoses were used to establish the DRG 
adjustments and were not accounted for in establishing the comorbidity 
category adjustments, except where ICD-9-CM code first instructions 
applied. In a code first situation, the submitted claim goes through 
the CMS processing system, which identifies the principal diagnosis 
code as non-psychiatric and searches the secondary codes for a 
psychiatric code to assign an MS-DRG code for adjustment. The system 
continues to search the secondary codes for those that are appropriate 
for a comorbidity adjustment.
    In FY 2025, we revised the comorbidity adjustment factors based on 
the results of the 2019 through 2021 regression analysis described in 
the FY 2025 IPF PPS final rule (89 FR 64606 through 64612). In 
addition, we made additions and changes to the comorbidity categories 
for which we adjust payment based on our analysis of ICD-10-CM codes 
currently included in each category as well as public comments received 
in response to the FY 2022 and FY 2023 IPF PPS proposed rules. A 
detailed discussion of the revised comorbidity adjustment factors is 
described in the FY 2025 IPF PPS final rule (89 FR 64606 through 
64612).
    We did not propose any changes to the comorbidity adjustment 
factors, and we are retaining the existing comorbidity adjustment 
factors for FY 2027. The FY 2027 comorbidity adjustment factors are 
found in Addendum A to this final rule, available on the CMS website at 
https://www.cms.gov/medicare/payment/prospective-payment-systems/inpatient-psychiatric-facility-pps/tools-and-worksheets.
    As noted previously, it is our policy to maintain the same 
diagnostic coding set for IPFs that is used under the IPPS for 
providing the same psychiatric care. In the FY 2015 IPF PPS final rule 
(79 FR 45947 through 45955), the comorbidity categories formerly 
defined using ICD-9-CM codes were converted to ICD-10-CM/PCS. The goal 
for converting the comorbidity categories is referred to as 
replication, meaning that the payment adjustment for a given patient 
encounter is the same after ICD-10-CM implementation as it would be if 
the same record had been coded in ICD-9-CM and submitted prior to ICD-
10-CM/PCS implementation on October 1, 2015. All conversion efforts 
were made with the intent of achieving this goal.
    As discussed in section IV.C.2.a. of this final rule, in the FY 
2025 IPF PPS final rule (89 FR 64602 and 64603) we adopted an April 1 
implementation date for ICD-10-CM diagnosis and ICD-10-PCS procedure 
code updates, in addition to the annual October 1 update, beginning 
with April 1, 2025 for the IPF PPS. Coding updates related to the IPF 
PPS comorbidity categories are adopted following a sub-regulatory 
process as finalized in the FY 2025 IPF PPS final rule (89 FR 64602 and 
64603). For April 1, 2026, we added three ICD-10-PCS procedure codes to 
the Oncology Treatment Procedures list and two ICD-10-PCS procedure 
codes to the Chronic Obstructive Pulmonary Disease & Sleep Apnea 
Procedures list. We did not receive any comments on the April 1, 2026, 
coding changes.
    For this FY 2027 IPF PPS final rule, we are adding 10 ICD-10-CM 
diagnosis codes to the Poisoning code list, nine ICD-10-CM diagnosis 
codes to the Cardiac Conditions list, three ICD-10-CM diagnosis codes 
to the Oncology Treatment Diagnoses list, and six ICD-10-CM diagnosis 
codes to the Severe Musculoskeletal and Connective Tissue Diseases 
list. In addition, we are removing eight ICD-10-CM diagnosis codes from 
the Severe Musculoskeletal and Connective Tissue Diseases list, and 12 
ICD-10-CM diagnosis codes from the Code First list. The final FY 2027 
comorbidity codes are shown in Addenda B, available on the CMS website 
at https://www.cms.gov/medicare/payment/prospective-payment-systems/inpatient-psychiatric-facility-pps/tools-and-worksheets.
c. Patient Age Adjustments
    As explained in the RY 2005 IPF PPS final rule (69 FR 66922), we 
analyzed the impact of age on per diem cost by examining the age 
variable (range of ages) for payment adjustments. In general, we found 
that the cost per day increases with age. The older age groups are 
costlier than the under 45 age group, the differences in per diem cost 
increase for each successive age group, and the differences are 
statistically significant. In FY 2025, we adopted revised patient age 
adjustments derived from the regression model using a blended set of 
2019 through 2021 data (89 FR 64612 and 64613). We did not propose any 
changes to the patient age adjustment factors, and we are retaining the 
existing patient age adjustment factors for FY 2027, as shown in 
Addendum A of this final rule (see https://www.cms.gov/medicare/payment/prospective-payment-systems/inpatient-psychiatric-facility-pps/
tools-and-worksheets).
d. Variable per Diem Adjustments
    We explained in the RY 2005 IPF PPS final rule (69 FR 66946) that 
the regression analysis indicated that per diem cost declines as the 
LOS increases. The variable per diem adjustments to the Federal per 
diem base rate account for ancillary and administrative costs that 
occur disproportionately in the first days after admission to an IPF. 
As discussed in the RY 2005 IPF PPS final rule, where a complete 
discussion of the variable per diem adjustments can be found, we used a 
regression analysis to estimate the average differences in per diem 
cost among stays of different lengths (69 FR 66947 through 66950). As a 
result of this analysis, we established variable per diem adjustments 
that begin on day 1 and decline gradually over the course of the 
patient's stay. In addition, the adjustment applied to day 1 depends 
upon whether the IPF has a qualifying ED. If an IPF has a qualifying 
ED, it receives a higher adjustment factor for day 1 of each stay than 
it would receive if it did not have a qualifying ED. The ED adjustment 
is explained in more detail in section IV.D.5. of this final rule.
    In FY 2025, we revised the variable per diem adjustment factors 
based on the 2019 through 2021 regression analysis (89 FR 64613 and 
64614). We did not propose any changes to the variable per diem 
adjustment factors, and we are retaining the existing variable per diem 
adjustment factors for FY 2027, as shown in Addendum A of

[[Page 48524]]

this final rule (available at https://www.cms.gov/medicare/payment/prospective-payment-systems/inpatient-psychiatric-facility-pps/tools-
and-worksheets).

D. Updates to the IPF PPS Facility-Level Adjustments

    The IPF PPS includes facility-level adjustments for the wage index, 
IPFs located in rural areas, teaching IPFs, cost of living adjustments 
for IPFs located in Alaska and Hawaii, and IPFs with a qualifying ED. 
The IPF PPS facility-level adjustment factors for rural location and 
teaching status were originally derived from regression analysis of 100 
percent of the FY 2002 MedPAR data file. For a more detailed 
description of the data file used for this regression analysis, we 
refer readers to the RY 2005 IPF PPS final rule (69 FR 66935 and 
66936).
    In FY 2026, in a continuation of the FY 2025 implementation of 
revisions to the methodology for determining payment rates under the 
IPF PPS as required by section 1886(s)(5)(D) of the Act, we revised the 
facility-level adjustment factors for rural location and teaching 
status based on a regression analysis of cost and claims data for IPF 
stays from FY 2020 to FY 2022 (90 FR 37639 through 37649). As discussed 
in the following sections, we proposed annual updates to the FY 2027 
IPF PPS wage index and to the cost of living adjustments for IPFs 
located in Alaska and Hawaii. For FY 2027, we proposed to use the 
facility-level adjustment factors for rural location, teaching status, 
and IPFs with a qualifying ED currently in effect for FY 2026, as shown 
in Addendum A to this final rule.
1. Wage Index Adjustment
a. Background
    As discussed in the RY 2007 IPF PPS final rule (71 FR 27061), and 
the RY 2009 IPF PPS (73 FR 25719) and RY 2010 IPF PPS notices (74 FR 
20373), to provide an adjustment for geographic wage levels, the labor-
related portion of an IPF's payment is adjusted using an appropriate 
wage index. Currently, an IPF's geographic wage index value is 
determined based on the actual location of the IPF in an urban or rural 
area, as defined in Sec.  412.64(b)(1)(ii)(A) and (C).
    Due to the variation in costs and because of the differences in 
geographic wage levels, in the RY 2005 IPF PPS final rule, we required 
that payment rates under the IPF PPS be adjusted by a geographic wage 
index. We proposed and finalized a policy to use the unadjusted, pre-
floor, pre-reclassified IPPS hospital wage index to account for 
geographic differences in IPF labor costs. We implemented use of the 
pre-floor, pre-reclassified IPPS hospital wage data to compute the IPF 
wage index since there was not an IPF-specific wage index available. We 
believe that IPFs generally compete in the same labor market as IPPS 
hospitals, and therefore, the pre-floor, pre-reclassified IPPS hospital 
wage data should be reflective of labor costs of IPFs. We believe this 
pre-floor, pre-reclassified IPPS hospital wage index to be the best 
available data to use as proxy for an IPF-specific wage index. As 
discussed in the RY 2007 IPF PPS final rule (71 FR 27061 through 
27067), under the IPF PPS, the wage index is calculated using the IPPS 
wage index for the labor market area in which the IPF is located, 
without considering geographic reclassifications, floors, and other 
adjustments made to the wage index under the IPPS. For a complete 
description of these IPPS wage index adjustments, we refer readers to 
the FY 2019 IPPS/LTCH PPS final rule (83 FR 41362 through 41390). Our 
wage index policy at Sec.  412.424(a)(2) provides that we use the best 
Medicare data available to estimate costs per day, including an 
appropriate wage index to adjust for wage differences.
    When the IPF PPS was implemented in the RY 2005 IPF PPS final rule, 
with an effective date of January 1, 2005, the pre-floor, pre-
reclassified IPPS hospital wage index that was available at the time 
was the FY 2005 pre-floor, pre-reclassified IPPS hospital wage index. 
Historically, the IPF wage index for a given RY has used the pre-floor, 
pre-reclassified IPPS hospital wage index from the prior FY as its 
basis. This has been due in part to the pre-floor, pre-reclassified 
IPPS hospital wage index data that were available during the IPF 
rulemaking cycle, where an annual IPF notice or IPF final rule was 
usually published in early May. This publication timeframe was 
relatively early compared to other Medicare payment rules because the 
IPF PPS follows a RY, which was defined in the implementation of the 
IPF PPS as the 12-month period from July 1 to June 30 (69 FR 66927). 
Therefore, the best available data at the time the IPF PPS was 
implemented was the pre-floor, pre-reclassified IPPS hospital wage 
index from the prior FY (for example, the RY 2006 IPF wage index was 
based on the FY 2005 pre-floor, pre-reclassified IPPS hospital wage 
index).
    In the RY 2012 IPF PPS final rule, we changed the reporting year 
timeframe for IPFs from a RY to FY, which begins October 1 and ends 
September 30 (76 FR 26434 and 26435). In that FY 2012 IPF PPS final 
rule, we continued our established policy of using the pre-floor, pre-
reclassified IPPS hospital wage index from the prior year (that is, 
from FY 2011) as the basis for the FY 2012 IPF wage index. This policy 
of basing a wage index on the prior year's pre-floor, pre-reclassified 
IPPS hospital wage index has been followed by other Medicare payment 
systems, such as hospice and inpatient rehabilitation facilities. By 
continuing with our established policy, we remained consistent with 
other Medicare payment systems.
    In FY 2020, we finalized the IPF wage index methodology to align 
the IPF PPS wage index with the same wage data timeframe used by the 
IPPS for FY 2020 and subsequent years. Specifically, we finalized the 
use of the pre-floor, pre-reclassified IPPS hospital wage index from 
the FY concurrent with the IPF FY as the basis for the IPF wage index. 
For example, the FY 2020 IPF wage index was based on the FY 2020 pre-
floor, pre-reclassified IPPS hospital wage index rather than on the FY 
2019 pre-floor, pre-reclassified IPPS hospital wage index.
    We explained in the FY 2020 proposed rule (84 FR 16973), that using 
the concurrent pre-floor, pre-reclassified IPPS hospital wage index 
will result in the most up-to-date wage data being the basis for the 
IPF wage index. We noted that it would also result in more consistency 
and parity in the wage index methodology used by other Medicare payment 
systems. We indicated that the Medicare skilled nursing facility (SNF) 
PPS already used the concurrent IPPS hospital wage index data as the 
basis for the SNF PPS wage index. We proposed and finalized similar 
policies to use the concurrent pre-floor, pre-reclassified IPPS 
hospital wage index data in other Medicare payment systems, such as 
hospice and inpatient rehabilitation facilities. Thus, the wage 
adjusted Medicare payments of various provider types are based upon 
wage index data from the same timeframe.
    In the FY 2023 IPF PPS final rule (87 FR 46856 through 46859), we 
finalized a permanent 5-percent cap on any decrease to a provider's 
wage index from its wage index in the prior year, and we stated that we 
will apply this cap in a budget neutral manner. In addition, we 
finalized a policy that a new IPF will be paid the wage index for the 
area in which it is geographically located for its first full or 
partial FY with no cap applied because a new IPF will not have a wage 
index in the prior FY. We amended the IPF PPS

[[Page 48525]]

regulations at Sec.  412.424(d)(1)(i) to reflect this permanent cap on 
wage index decreases. We refer readers to the FY 2023 IPF PPS final 
rule for a more detailed discussion about this policy.
    For FY 2027, we proposed to apply the IPF wage index adjustment to 
the labor-related share of the national IPF PPS base rate and ECT 
payment per treatment. As discussed in section IV.A.3. of this final 
rule, the labor-related share of the IPF PPS national base rate and ECT 
payment per treatment is 78.9 percent in FY 2027. This percentage 
reflects the labor-related share relative importance of the 2021-based 
IPF market basket for FY 2027 and is 0.1 percentage point lower than 
the FY 2026 labor-related share.
    For FY 2027, we proposed to continue to use the concurrent pre-
floor, pre-reclassified IPPS hospital wage index as the basis for the 
IPF wage index. We explained that we continue to consider this an 
appropriate source of wage index data to estimate costs per day, in 
accordance with our longstanding wage index policy at Sec.  
412.424(a)(2)(ii).
    The following is a summary of the comments we received on the 
proposed wage index adjustment.
    Comment: Several commenters expressed support for the proposed use 
of the concurrent pre-floor, pre-reclassified IPPS hospital wage index 
as the basis for the IPF wage index pre-floor for FY 2027. Commenters 
agreed with CMS that IPFs compete in the same labor market as 
hospitals. Other commenters stated that IPFs compete within a distinct 
labor market that includes community-based behavioral health providers, 
outpatient treatment programs, and correctional settings.
    Response: We appreciate these comments. We did not propose any 
changes to our longstanding IPF PPS wage index policy, which is based 
on the concurrent pre-floor, pre-reclassified IPPS hospital wage index. 
As we have previously stated, we believe that IPFs generally compete in 
the same labor market as IPPS hospitals. As discussed later in this 
final rule, we are considering whether alternative data sources could 
enhance the accuracy of the IPF wage index in future years, including 
the extent to which IPFs compete with other non-hospital settings for 
labor.
    Comment: Some commenters encouraged CMS to closely align the IPF 
wage index with various policies applied to the IPPS wage index, 
including reclassifications, application of the rural floor, and the 
use of a lower labor-related share for IPFs in low-wage areas.
    Response: We appreciate the commenters' recommendations. We did not 
propose the specific policies suggested by commenters, but we will take 
these recommendations into consideration to potentially inform future 
rulemaking. As we have previously discussed in the RY 2007 final rule 
(71 FR 27066), we believe that the actual location of an IPF (as 
opposed to the location of affiliated providers) is most appropriate 
for determining the wage adjustment because the prevailing wages in the 
area in which the IPF is located influence the cost of a case. In that 
same RY 2007 final rule (71 FR 27066), we also stated that we believe 
the ``rural floor'' is required only for the acute care hospital 
payment system because section 4410 of the Balanced Budget Act of 1997 
(Pub. L. 105-33) applies specifically to acute care hospitals and not 
excluded hospitals and excluded units. As we have previously discussed, 
the IPF wage index is intended to be a relative measure of the value of 
labor in prescribed labor market areas (87 FR 46857). In addition, 
there are a variety of reasons why our longstanding IPF wage index 
policy has not applied floors or reclassifications, which, as we 
previously noted, are not applied to the IPF wage index by statute. For 
example, applying floors and reclassifications to the IPF wage index 
would significantly increase administrative burden, both for IPFs and 
for CMS, associated with IPFs reclassifying from one CBSA to another, 
and it would significantly increase the complexity of the methodology. 
Furthermore, because floors and reclassifications would be applied 
budget-neutrally under the wage index, these policies would increase 
the wage index for some IPFs while reducing IPF PPS payments for all 
other IPFs, which would upset the long-settled expectations with which 
IPFs across the country have been operating. For these reasons, we 
believe using the pre-floor, pre-reclassified IPPS hospital wage index 
is the most appropriate data to use as a proxy for an IPF wage index. 
We appreciate the commenter's suggestion to apply an out-migration 
adjustment to IPFs to account for employment of hospital staff who 
commute to work in counties with a higher wage index. However, we note 
that the out-migration adjustment is applied to the IPPS hospital wage 
index under section 1886(d)(13) of the Act, which is a statutory 
provision that specifically applies to subsection (d) hospitals paid 
under the IPPS. As discussed in the prior paragraph, we do not believe 
it is appropriate for the IPF PPS to apply an out-migration adjustment 
that is not statutorily required, because such a policy would increase 
administrative burden and have distributional impacts on IPFs.
    Comment: A commenter recommended CMS apply the wage index 5-percent 
cap in a non-budget neutral manner.
    Response: We did not propose any new policies this year pertaining 
to the 5-percent cap, and accordingly, we are not finalizing any new 
policies in this final rule. In accordance with our longstanding policy 
under the IPF PPS, we updated the wage index in such a way that total 
estimated payments to IPFs for FY 2027 are the same with or without the 
changes (that is, in a budget-neutral manner) by applying a budget 
neutrality factor to the IPF PPS rates. We applied the wage index cap 
in a budget-neutral manner in accordance with this overall budget 
neutrality policy for the IPF PPS wage index so that wage index changes 
do not increase aggregate Medicare spending. In the FY 2023 IPF PPS 
proposed rule (87 FR 19423 through 19425), we noted that applying a 5-
percent cap on all wage index decreases would have a very small effect 
on the wage index budget neutrality factor for FY 2023. We explained 
that we anticipate that in the absence of proposed policy changes, most 
providers will not experience year-to-year wage index declines greater 
than 5 percent in any given year and that we expect the impact to the 
wage index budget neutrality factor in future years will continue to be 
minimal.
    Final Decision: After consideration of the comments received, we 
are finalizing our proposal for FY 2027 to continue to use the 
concurrent pre-floor, pre-reclassified IPPS hospital wage index as the 
basis for the IPF wage index. We will apply the IPF wage index 
adjustment to the labor-related share of the national rate and ECT 
payment per treatment. The labor-related share of the national rate and 
ECT payment per treatment will change from 79.0 percent in FY 2026 to 
78.9 percent in FY 2027. This percentage reflects the labor-related 
share of the 2021-based IPF market basket for FY 2027 (see section 
IV.A.3. of this final rule).
    Lastly, we explained in the proposed rule that we routinely assess 
whether more recent or alternative data sources may further enhance the 
accuracy and representativeness of our estimates. We noted that other 
payment systems have explored and are exploring alternative wage index 
methodologies under their specific programmatic and statutory 
circumstances. For example, CMS

[[Page 48526]]

finalized changes to the ESRD PPS wage index using Bureau of Labor 
Statistics (BLS) occupation-level wage data in the CY 2025 ESRD PPS 
final rule (89 FR 89116). We acknowledged that this approach was 
developed under the specific programmatic and statutory circumstances 
of the ESRD PPS and may not be directly transferable to the IPF PPS, 
but we stated that CMS is interested in exploring whether similar 
methodologies using publicly available wage data could be adapted to 
better reflect the geographic variation in labor costs for inpatient 
psychiatric facilities.
    We also noted that in its 2023 Report to Congress,\5\ MedPAC 
discussed various conceptual approaches to Medicare wage indexes, 
including the use of county-level wage data from BLS with an 
occupational mix to construct wage indexes that are more specific to 
the payment setting. We explained that MedPAC has previously written 
about using all-employer, occupation-level wage data to establish 
different weights for setting-specific occupational labor mixes as one 
approach to geographic adjustments.

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

    We solicited comments on whether we should consider using 
alternative data sources to construct an IPF-specific wage index for 
potential use in future years. CMS sought feedback to understand the 
potential advantages and limitations of using alternative data sources, 
such as BLS data and IPF cost reports, as well as other methodologies 
that interested parties believe could appropriately reflect the 
geographic variation in labor costs for psychiatric facilities. In 
addition, as discussed elsewhere in the Federal Register, we noted that 
we are also considering the potential use of alternative data sources 
in other payment systems including the Inpatient Rehabilitation 
Facilities PPS, Skilled Nursing Facilities PPS, and Hospice payment 
system. We sought feedback on the unique considerations applicable to 
IPFs that should inform how CMS could consider the potential use of 
alternative data sources.
    We received numerous comments in response to this comment 
solicitation. Commenters offered a wide variety of considerations 
related to the potential development of an IPF-specific wage index. 
These comments addressed specific aspects of the wage index methodology 
including information about the extent to which IPFs typically compete 
with other healthcare settings for labor, thoughts about potential 
sources of wage data, and considerations related to geographical 
categorization of IPFs. We thank the commenters for these suggestions, 
and we will take them into consideration as we consider potential 
future changes to the IPF PPS wage index.
b. Office of Management and Budget (OMB) Bulletins
    The wage index used for the IPF PPS is calculated using the 
unadjusted, pre-reclassified and pre-floor IPPS wage index data and is 
assigned to the IPF based on the labor market area in which the IPF is 
geographically located. IPF labor market areas are delineated based on 
the Core-Based Statistical Area (CBSAs) established by the OMB.
    Generally, OMB issues major revisions to statistical areas every 10 
years, based on the results of the decennial census. However, OMB 
occasionally issues minor updates and revisions to statistical areas in 
the years between the decennial censuses through OMB Bulletins. These 
bulletins contain information regarding CBSA changes, including changes 
to CBSA numbers and titles. In accordance with our established 
methodology, the IPF PPS has historically adopted any CBSA changes that 
are published in the OMB bulletin that corresponds with the IPPS 
hospital wage index used to determine the IPF wage index and, when 
necessary and appropriate, has proposed and finalized transition 
policies for these changes.
    In the RY 2007 IPF PPS final rule (71 FR 27061 through 27067), we 
adopted the changes discussed in OMB Bulletin No. 03-04 (June 6, 2003), 
which announced revised definitions for Metropolitan Statistical Areas 
(MSAs), and the creation of Micropolitan Statistical Areas and Combined 
Statistical Areas. We refer readers to the FY 2007 IPF PPS final rule 
(71 FR 27064 and 27065) for a complete discussion regarding treating 
Micropolitan Areas as rural. In adopting the OMB CBSA geographic 
designations in RY 2007, we did not provide a separate transition for 
the CBSA-based wage index since the IPF PPS was already in a transition 
period from TEFRA payments to PPS payments.
    In the RY 2009 IPF PPS notice, we incorporated the CBSA 
nomenclature changes published in the most recent OMB bulletin that 
applied to the IPPS hospital wage index used to determine the current 
IPF wage index and stated that we expected to continue to do the same 
for all the OMB CBSA nomenclature changes in future IPF PPS rules and 
notices, as necessary (73 FR 25721).
    Subsequently, CMS adopted the changes that were published in past 
OMB bulletins in the FY 2016 IPF PPS final rule (80 FR 46682 through 
46689), the FY 2018 IPF PPS rate update (82 FR 36778 and 36779), the FY 
2020 IPF PPS final rule (84 FR 38453 and 38454), and the FY 2021 IPF 
PPS final rule (85 FR 47051 through 47059). We direct readers to each 
of these rules for more information about the changes that were adopted 
and any associated transition policies.
    As discussed in the FY 2023 IPF PPS final rule, we did not adopt 
OMB Bulletin 20-01, which was issued March 6, 2020, because we 
determined this bulletin had no material impact on the IPF PPS wage 
index. This bulletin creates only one Micropolitan statistical area, 
and Micropolitan areas are considered rural for the IPF PPS wage index. 
That is, the constituent county of the new Micropolitan area was 
considered rural effective as of FY 2021 and would continue to be 
considered rural if we adopted OMB Bulletin 20-01.
    In the FY 2025 IPF PPS final rule (89 FR 64614 through 64633), we 
adopted the updates set forth in OMB Bulletin No. 23-01 effective July 
21, 2023, beginning with the FY 2025 IPF PPS wage index. These updates 
included adoption of material changes to the OMB statistical area 
delineations, which resulted in our determination that 53 urban 
counties became rural, 54 rural counties became urban, and 88 counties 
moved to a new or modified CBSA. These updates also included replacing 
the 8 counties in Connecticut with 9 new ``Planning Regions.'' Planning 
regions now serve as county-equivalents within the CBSA system. OMB 
Bulletin No. 23-01 may be accessed online at https://www.whitehouse.gov/wp-content/uploads/2023/07/OMB-Bulletin-23-01.pdf.
    Given the scope of changes involved in adopting the CBSA 
delineations for FY 2025, we finalized a budget neutral 3-year phase 
out policy for IPFs transitioning from rural to urban based on our 
adoption of CBSA revisions, as discussed further in section IV.D.2.b. 
of this final rule. We also applied the permanent 5-percent cap on wage 
index decreases described at Sec.  412.424(d)(1)(i).
c. Wage Index Budget Neutrality Adjustment
    In accordance with Sec.  412.424(c)(5), changes to the wage index 
are made in a budget neutral manner so that updates do not increase 
expenditures. Therefore, for FY 2027, we proposed to continue to apply 
a budget neutrality adjustment in accordance with our existing budget 
neutrality policy. This policy requires us to update the wage index in 
such a

[[Page 48527]]

way that total estimated payments to IPFs for FY 2027 are the same with 
or without the changes (that is, in a budget neutral manner) by 
applying a budget neutrality factor to the IPF PPS rates. We proposed 
to use the following steps to ensure that the rates reflect the FY 2027 
update to the wage indexes (based on FY 2023 hospital cost report data) 
and the labor-related share in a budget-neutral manner:
    Step 1: Simulate estimated IPF PPS payments, using the FY 2026 IPF 
wage index values (available on the CMS website) and labor-related 
share (as published in the FY 2026 IPF PPS final rule (90 FR 37635)).
    Step 2: Simulate estimated IPF PPS payments using the FY 2027 IPF 
wage index values (available on the CMS website), and the FY 2027 
labor-related share (based on the latest available data as discussed 
previously).
    Step 3: Divide the amount calculated in step 1 by the amount 
calculated in step 2. The resulting quotient is the FY 2027 budget 
neutral wage adjustment factor of 0.9989.
    Step 4: Apply the FY 2027 budget neutral wage adjustment factor 
from step 3 to the FY 2026 IPF PPS Federal per diem base rate after the 
application of the IPF market basket increase reduced by the 
productivity adjustment described in section IV.A.2. of this final rule 
to determine the final FY 2027 IPF PPS Federal per diem base rate.
2. Adjustment for Rural Location
a. Payment for Rural Location
    In the RY 2005 IPF PPS final rule (69 FR 66954), we provided a 17-
percent payment adjustment for IPFs located in a rural area. This 
adjustment was based on the regression analysis, which indicated that 
the per diem cost of rural facilities was 17 percent higher than that 
of urban facilities after accounting for the influence of the other 
variables included in the regression. This 17-percent adjustment has 
been part of the IPF PPS each year since the inception of the IPF PPS. 
In the FY 2025 IPF PPS final rule, we revised the patient-level 
adjustment factors and adopted the new CBSA delineations. To minimize 
the scope of changes that would impact providers in any single year, we 
maintained the existing regression-derived adjustment factor, which was 
established in RY 2005, for IPFs located in a rural area for FY 2025. 
Our analysis of more cost and claims data from FY 2020 through 2022 for 
the FY 2026 final rule indicated that an increase in the payment 
adjustment for IPFs in rural areas would be appropriate. Based on this 
analysis, we revised the adjustment for rural location to 18 percent 
for FY 2026 to more accurately represent the difference in costs 
between urban and rural IPFs (90 FR 37647). See the FY 2026 IPF PPS 
final rule for the full explanation of the regression analysis that 
yielded the revised 18 percent adjustment for rural location (90 FR 
37639 through 37644) and the RY 2005 IPF PPS final rule (69 FR 66954) 
for a complete discussion of the adjustment for rural locations.
    We did not propose any changes to the 18 percent adjustment factor 
for IPFs located in a rural area.
b. End of Rural Transition
    The adoption of OMB Bulletin No. 23-01 in the FY 2025 IPF PPS final 
rule (89 FR 64632) in accordance with our established methodology 
determines whether a facility is classified as urban or rural for 
purposes of the rural payment adjustment in the IPF PPS. Adoption of 
the updated OMB delineations results in the rural payment adjustment 
being applied where it is appropriate to adjust for higher costs 
incurred by IPFs in rural locations; however, these changes have 
distributional effects among IPF providers. Some providers lost 
eligibility for the rural payment adjustment in FY 2025 as a result of 
these changes. Therefore, we provided a transition period to adopt the 
updated OMB delineations (89 FR 64633).
    In the FY 2025 IPF PPS final rule, we phased out the rural 
adjustment for facilities located in a county that transitioned from 
rural to urban due to the changes outlined in OMB Bulletin 23-01. We 
implemented a 3-year budget neutral phase-out of the rural adjustment 
for IPFs located in the 54 rural counties that would become urban under 
our adoption of the new OMB delineations, given the potentially 
significant payment impacts for these IPFs (89 FR 64632 and 64633), 
consistent with the transition policy we adopted for IPFs in FY 2016 
(80 FR 46682 through 46689). Under this 3-year phase-out, for FY 2026, 
IPFs that became urban due to our adoption of these OMB delineation 
changes received one-third of the rural adjustment that was applicable 
in FY 2024. For FY 2027, these IPFs will not receive a rural 
adjustment.
3. Teaching Adjustment
    In the RY 2005 IPF PPS final rule, we implemented regulations at 
Sec.  412.424(d)(1)(iii) to establish a facility-level adjustment for 
IPFs that are, or are part of, teaching hospitals (69 FR 66954 through 
66957). The teaching adjustment accounts for the higher indirect 
operating costs experienced by hospitals that participate in graduate 
medical education (GME) programs. As detailed further in the following 
paragraphs, the payment adjustments are made based on the ratio of the 
number of fulltime equivalent (FTE) interns and residents training in 
the IPF to the IPF's average daily census.
    Medicare makes direct GME payments (for direct costs such as 
resident and teaching physician salaries, and other direct teaching 
costs) to all teaching hospitals, including those paid under a PPS and 
those paid under the TEFRA rate-of-increase limits. These direct GME 
payments are made separately from payments for hospital operating costs 
and are not part of the IPF PPS. The direct GME payments do not address 
the estimated higher indirect operating costs teaching hospitals may 
face.
    The results of the regression analysis of FY 2002 IPF data 
established the basis for the payment adjustments included in the RY 
2005 IPF PPS final rule. The results showed that the indirect teaching 
cost variable is significant in explaining the higher costs of IPFs 
that have teaching programs. We calculated the teaching adjustment 
based on the IPF's ``teaching variable,'' which is (1 + [the number of 
FTE residents training in the IPFs divided by the IPF's average daily 
census]). The teaching variable was then raised to the 0.5150 power, 
resulting in the IPF PPS teaching adjustment. This formula is subject 
to limitations on the number of FTE residents, which are discussed in 
greater detail in the following paragraph.
    We established the teaching adjustment in a manner that limited the 
incentives for IPFs to add FTE residents for the purpose of increasing 
their teaching adjustment. We imposed a cap on the number of FTE 
residents that may be counted for purposes of calculating the teaching 
adjustment. The cap limits the number of FTE residents that teaching 
IPFs may count for the purpose of calculating the IPF PPS teaching 
adjustment, not the number of residents teaching institutions can hire 
or train. We calculated the number of FTE residents that trained in the 
IPF during a ``base year'' and used that FTE resident number as the 
cap. An IPF's FTE resident cap is ultimately determined based on the 
final settlement of the IPF's most recent cost report filed before 
November 15, 2004 (69 FR 66955). A complete discussion of the temporary 
adjustment to the FTE cap to reflect residents due to hospital closure 
or residency program closure appears in the RY 2012 IPF PPS

[[Page 48528]]

proposed rule (76 FR 5018 through 5020) and the RY 2012 IPF PPS final 
rule (76 FR 26453 through 26456). As discussed in section IV.D.6.c. of 
the FY 2026 IPF PPS final rule (90 FR 37649 through 37651), we made 
conforming changes to the IPF resident cap policy beginning in FY 2026 
to recognize permanent cap increases awarded under section 4122 of the 
CAA, 2023.
    In the regression analysis that informed the RY 2004 IPF PPS final 
rule, the logarithm of the teaching variable had a coefficient value of 
0.5150. We converted this cost effect into a teaching payment 
adjustment by treating the regression coefficient as an exponent and 
raising the teaching variable to a power equal to the coefficient 
value. We note that the coefficient value of 0.5150 was based on the 
regression analysis holding all other components of the payment system 
constant. A complete discussion of how the teaching adjustment was 
calculated appears in the RY 2005 IPF PPS final rule (69 FR 66954 
through 66957) and the RY 2009 IPF PPS notice (73 FR 25721).
    In the FY 2025 IPF PPS proposed rule, we included an RFI regarding 
a potential revision to the payment adjustment for teaching status (89 
FR 23194 and 23195); we refer readers to section IV.A. of the FY 2025 
IPF PPS final rule (89 FR 64641) for summaries of the comments we 
received and our responses. We took the comments received into 
consideration when we developed our proposal for the FY 2026 revision 
of the payment adjustment for teaching status.
    In the FY 2026 IPF PPS final rule, we increased the teaching 
adjustment to 0.7957 based on the results of our latest regression 
model (90 FR 37648 and 37649). This cost effect is converted to a 
teaching payment adjustment by treating the regression coefficient as 
an exponent and raising the teaching variable to a power equal to the 
coefficient value. We implemented this revision to the teaching 
adjustment budget-neutrally.
    For FY 2027, we did not propose any changes to the teaching 
adjustment.
4. Cost of Living Adjustment for IPFs Located in Alaska and Hawaii
    The IPF PPS includes a payment adjustment for IPFs located in 
Alaska and Hawaii based upon the area in which the IPF is located. As 
we explained in the RY 2005 IPF PPS final rule, the FY 2002 data 
demonstrated that IPFs in Alaska and Hawaii had per diem costs that 
were disproportionately higher than other IPFs. As a result of this 
analysis, we provided a COLA in the RY 2005 IPF PPS final rule. We 
refer readers to the FY 2024 IPF PPS final rule for a complete 
discussion of the currently applicable COLA factors (88 FR 51088 and 
51089).
    In the FY 2013 IPPS/LTCH final rule (77 FR 53700 and 53701), we 
established a new methodology to update the COLA factors for Alaska and 
Hawaii and adopted this methodology for the IPF PPS in the FY 2015 IPF 
PPS final rule (79 FR 45958 through 45960). We also specified that the 
COLA updates will be determined every 4 years, in alignment with the 
IPPS market basket labor-related share update (79 FR 45958 through 
45960). Because the labor-related share of the IPPS market basket was 
updated for FY 2022, the COLA factors were updated in FY 2022 IPPS/LTCH 
rulemaking (86 FR 45547) reflecting CPI data through 2020. As such, we 
also finalized an update to the IPF PPS COLA factors in the FY 2022 IPF 
PPS final rule to reflect the updated COLA factors finalized in the FY 
2022 IPPS/LTCH rulemaking effective for FY 2022 through FY 2025 (86 FR 
42621 and 42622).
    In the FY 2026 IPF PPS final rule, we stated that we believe it is 
appropriate to have a consistent policy approach with that of other 
hospitals in Alaska and Hawaii (90 FR 37651 and 37652). We used the FY 
2025 COLA factors to adjust the non-labor-related portion of the 
standardized amount for IPFs located in Alaska and Hawaii for FY 2026. 
For a complete discussion of the FY 2026 COLA factors, we refer readers 
to the FY 2026 IPPS/LTCH final rule (90 FR 37229 and 37230).
    Effective for FY 2027, to continue our consistent policy approach 
with that of other hospitals in Alaska and Hawaii, we proposed to 
adjust non-labor related costs for IPFs located in Alaska and Hawaii 
using the Overseas Cost-of-Living Allowance (OCOLA) data \6\ published 
by the Department of War (DOW). We believe the DOW OCOLAs are an 
appropriate data source to capture the cost differences of hospital 
non-labor-related inputs purchased in the areas in Hawaii and Alaska 
compared to the continental U.S. Additionally, we proposed to no longer 
cap the COLA factors for Alaska and Hawaii at 25 percent. We also 
solicited any additional information with regard to these results.
---------------------------------------------------------------------------

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

    For this FY 2027 IPF PPS final rule, we are finalizing our proposed 
methodology to derive the COLA factors for IPFs located in Alaska and 
Hawaii using the DOW OCOLAs. In addition, we are finalizing our 
proposal to no longer cap the COLA factors for Alaska and Hawaii at 25 
percent. Based on comments received under the IPPS, we are finalizing a 
``hold harmless'' policy in FY 2027 for any area that would experience 
a reduction to their COLA factor under the OCOLA methodology. For a 
complete discussion of the FY 2027 COLA factors, we refer readers to 
the FY 2027 IPPS/LTCH proposed rule (91 FR 19813 and 19814) and the FY 
2027 IPPS/LTCH final rule, published elsewhere in the Federal Register. 
The FY 2027 IPF PPS COLA factors for Alaska and Hawaii are shown in 
Table 2.

    The IPF PPS COLA factors for Alaska and Hawaii for FY 2027 are also 
shown in Addendum A to this final rule, which is available on the CMS 
website at https://www.cms.gov/medicare/payment/prospective-payment-systems/inpatient-psychiatric-facility-pps/tools-and-worksheets.
5. Adjustment for IPFs With a Qualifying ED
    The IPF PPS includes a facility-level adjustment for IPFs with 
qualifying EDs. As defined in Sec.  412.402, qualifying emergency 
department means an emergency department that is staffed and equipped 
to furnish a comprehensive array of emergency services and meets the 
requirements of Sec.  489.24(b) and Sec.  413.65.
    We provide an adjustment to the Federal per diem base rate to 
account for the costs associated with maintaining a full-service ED. 
The adjustment is intended to account for ED costs incurred by a 
psychiatric hospital with a qualifying ED, or an excluded psychiatric 
unit of an IPPS hospital or a critical access hospital (CAH), and the 
overhead cost of maintaining the ED. This payment applies to all IPF 
admissions (with one exception which we describe in this section), 
regardless of whether the patient was admitted through the ED. The ED 
adjustment is made on every qualifying claim except as described in 
this section. As specified at Sec.  412.424(d)(1)(v)(B), the ED 
adjustment is not made when a patient is discharged from an IPPS 
hospital or CAH and admitted to the same IPPS hospital's or CAH's 
excluded psychiatric unit. We clarified in the RY 2005 IPF PPS final 
rule (69 FR 66960) that an ED adjustment is not made in this case 
because the costs associated with ED services are reflected in the DRG 
payment to the IPPS hospital or through the reasonable cost payment 
made to the CAH.
    In the FY 2025 IPF PPS final rule, we updated the adjustment factor 
from 1.31 to 1.54 for IPFs with qualifying EDs using the same 
methodology used to determine ED adjustments in prior years (89 FR 
64636). Beginning in FY 2025, IPFs with a qualifying ED receive an 
adjustment factor of 1.54 as the variable per diem adjustment for day 1 
of each patient stay. If an IPF does not have a qualifying ED, it 
receives an adjustment factor of 1.27 as the variable per diem 
adjustment for day 1 of each patient stay. A complete discussion of the 
steps involved in the most recent calculation of the ED adjustment 
factor can be found in the FY 2025 IPF PPS final rule (89 FR 64636).
    For FY 2027, we did not propose any changes to the adjustment 
factor for IPFs with qualifying EDs.

E. Other Payment Adjustments and Policies

1. Outlier Payment Overview
a. Background on the Current IPF PPS Outlier Payment Policy
    The IPF PPS includes an outlier adjustment to promote access to IPF 
care for those patients who require expensive care and to limit the 
financial risk of IPFs treating unusually costly patients. In the RY 
2005 IPF PPS final rule, we implemented regulations at Sec.  
412.424(d)(3)(i) to provide a per case payment for IPF stays that are 
extraordinarily costly. Providing an outlier adjustment to IPFs for 
extremely costly cases strongly improves the accuracy of the IPF PPS in 
determining resource costs at the patient- and facility-level. These 
upward payment adjustments reduce the financial losses that would 
otherwise be incurred in treating patients who require costlier care, 
and therefore, reduce the incentives for IPFs to under-serve these 
patients. We make payments under the outlier adjustment for discharges 
where an IPF's estimated total cost for a case exceeds a fixed dollar 
loss threshold amount (multiplied by the IPF's facility-level 
adjustments) plus the Federal per diem payment amount for the case.
    In instances when the case qualifies for an outlier payment 
adjustment, we pay 80 percent of the difference between the estimated 
cost for the case and the adjusted threshold amount for days 1 through 
9 of the stay (consistent with the median LOS for IPFs in FY 2002), and 
60 percent of the difference for day 10 and thereafter. The adjusted 
threshold amount is equal to the outlier threshold amount adjusted for 
wage area, teaching status, rural area, and the COLA factor (if 
applicable), plus the amount of the Medicare IPF payment for the case. 
We established the 80 percent and 60 percent loss sharing ratios 
because we were concerned that a single ratio established at 80 percent 
(like other Medicare PPSs) might provide an incentive under the IPF per 
diem

[[Page 48530]]

payment system to increase LOS to receive additional payments.
    After establishing the loss sharing ratios, we determined the 
current fixed dollar loss threshold amount through payment simulations 
designed to compute a dollar loss beyond which payments are estimated 
to meet the 2 percent outlier spending target. Each year when we update 
the IPF PPS, we simulate payments using the latest available data to 
compute the fixed dollar loss threshold so that outlier payments 
represent 2 percent of total estimated IPF PPS payments.
b. Analysis of Recent Outlier Payments Under the Current Methodology
    In the proposed rule, we explained that we conducted an analysis of 
the latest available data (the December 2025 update of FY 2025 IPF 
claims) and rate increases, following our longstanding methodology. We 
stated that based on an analysis of these updated data, we believe it 
is necessary to update the fixed dollar loss threshold amount to 
maintain an outlier percentage that equals 2 percent of total estimated 
IPF PPS payments. We estimated that IPF outlier payments as a 
percentage of total estimated payments would be 2.2 percent in FY 2026. 
Therefore, we proposed to update the outlier threshold amount to 
$42,720 to maintain estimated outlier payments at 2 percent of total 
estimated aggregate IPF payments for FY 2027. We noted that this update 
would be an increase from the FY 2026 threshold of $39,360.
    For the FY 2027 proposed rule, we analyzed the distribution of IPF 
PPS outlier payments. Comparison of outlier payments in RY 2005 and FY 
2027 demonstrated that IPF outlier payments are now concentrated among 
a smaller number of stays with significantly higher average costs and 
among a smaller number of IPFs. In FY 2025, the 20 IPFs that had the 
highest amounts of total outlier payments accounted for more than 50 
percent of total outlier payments.
    We also analyzed clinical characteristics from IPF PPS claims to 
determine the extent to which such differences could be driving outlier 
payments. Outlier stays tended to be significantly longer than non-
outlier stays (approximately 46 days versus 12 days) and tended to have 
significantly higher daily routine charges. Although we noted that 
there were certain case-mix differences between providers with a high 
share of outliers and those with a lower share or with no outliers, our 
analysis indicated that these differences alone did not fully explain 
the substantial difference in per diem routine charges. We explained in 
the proposed rule that our analyses of clinical characteristics of 
outlier stays suggested that a substantial share of outlier payments 
may be driven by higher facility-level costs rather than by patient 
complexity. We refer readers to the FY 2027 IPF PPS proposed rule (91 
FR 17732 and 17733) for a detailed account of our analysis and 
findings.
    As discussed in the following sections, we proposed changes to our 
outlier policy and the methodology for determining the outlier fixed 
dollar loss threshold amount for FY 2027.
c. Changes to the Outlier Payment Policy and Update to the Outlier 
Fixed Dollar Loss Threshold Amount
    In accordance with the update methodology described in Sec.  
412.428(d)(3)(i)(D), we proposed to update the fixed dollar loss 
threshold amount used under the IPF PPS outlier policy. Based on the 
regression analysis and payment simulations used to develop the IPF 
PPS, we established a 2 percent outlier policy, which strikes an 
appropriate balance between protecting IPFs from extraordinarily costly 
cases while ensuring the adequacy of the Federal per diem base rate for 
all other cases that are not outlier cases. We proposed to maintain the 
established 2 percent outlier policy for FY 2027.
    Our longstanding methodology for updating the outlier fixed dollar 
loss threshold involves using the best available data, which is 
typically the most recent available data. We note that for FY 2022 and 
FY 2023 only, we made certain methodological changes to our modeling of 
outlier payments, and we discussed the specific circumstances that led 
to those changes for those years (86 FR 42623 and 42624; 87 FR 46862 
through 46864). We direct readers to the FY 2022 and FY 2023 IPF PPS 
proposed and final rules for a more complete discussion.
    We proposed to update the IPF outlier threshold amount for FY 2027 
using FY 2025 claims data in accordance with the methodology that we 
have used to set the initial outlier threshold amount each year 
beginning with the RY 2007 IPF PPS final rule (71 FR 27072 and 27073). 
That is, we proposed to determine the FY 2027 fixed dollar loss 
threshold amount through payment simulations designed to compute a 
dollar loss beyond which payments are estimated to meet the 2 percent 
outlier spending target. However, we proposed to change the outlier 
policy for FY 2027 to minimize the impact of a small number of high-
cost IPFs on the outlier fixed dollar loss threshold amount. 
Accordingly, we proposed to modify our methodology for simulating 
payments to determine the outlier fixed dollar loss threshold amount 
for FY 2027. As we discuss in the following paragraphs, we estimated 
that this proposed change to the outlier policy would have a meaningful 
impact on the outlier fixed dollar loss threshold amount in FY 2027.
    In summary, we proposed to modify the IPF PPS outlier payment 
policy beginning in FY 2027 to better align outlier payments with their 
intended purpose of promoting access to care for patients requiring 
unusually costly treatment while ensuring an appropriate distribution 
of outlier payments across all IPFs. We note that the authorizing 
language for the IPF PPS, Section 124 of the BBRA, requires that the 
IPF PPS include an adequate patient classification system that reflects 
the differences in patient resource use and costs among IPFs. The IPF 
PPS has a longstanding policy of making appropriate adjustments for 
other factors that drive resource use and costs among IPFs, and of 
doing so in a way that limits incentives for inappropriate utilization. 
The IPF PPS facility-level adjustments strengthen the accuracy of the 
IPF PPS in adjusting payment to align with resource costs that are 
associated with rural status, geographical location, the presence of a 
full-service ED, and the higher indirect operating costs experienced by 
hospitals that participate in GME programs. As discussed in section 
IV.D.3. of this final rule, we established the teaching adjustment in a 
manner that limited the incentives for IPFs to add FTE residents for 
the purpose of increasing their teaching adjustment by imposing a cap 
on the number of FTE residents that may be counted for purposes of 
calculating the teaching adjustment.
    In addition, section 1886(s)(5)(D) of the Act authorizes the 
Secretary to implement revisions to the methodology for determining the 
payment rates under the IPF PPS, for FY 2025 and subsequent years. We 
explained in the proposed rule that given the emphasis on patient- and 
facility-level cost differences in Section 124 of the BBRA, and under 
the authority of section 1886(s)(5)(D) of the Act to consider and 
implement revisions to our payment methodology, it is appropriate to 
ensure that IPF outlier payments recognize patient-level cost 
differences across a broad range of services and facilities. We 
considered the precedent of the IPF PPS teaching cap policy as a 
potential tool to strengthen the accuracy of the IPF PPS by limiting 
potential incentives for IPFs to inappropriately increase their

[[Page 48531]]

costs and charges for IPF services. We explained that our analysis of 
recent claims data revealed that outlier payments have become 
increasingly concentrated among a small subset of facilities with 
exceptionally high reported costs. According to our simulations, each 
of these providers' outlier payments would account for more than 20 
percent of its total IPF PPS payments. For additional information about 
the characteristics of providers included in our payment simulations 
for this FY 2027 IPF PPS final rule, see the FY 2027 IPF PPS Final Rate 
Setting Impact File, available on the CMS web page for the FY 2027 IPF 
PPS final rule at https://www.cms.gov/medicare/payment/prospective-payment-systems/inpatient-psychiatric-facility/ipf-pps-regulations-and-notices.
    As we discussed in the proposed rule, we observed that these 
facilities' high overall costs are primarily driven by elevated routine 
costs, which can include costs such as labor, real estate, or overhead 
expenses. We noted that routine costs are fixed at the provider level 
and do not vary based on individual patient characteristics or 
treatment intensity. We explained that outlier stays tend to be 
significantly longer than non-outlier stays; however, since the IPF PPS 
is a per diem payment system in which a longer length of stay results 
in higher payment, this difference only drives outlier payments when 
daily costs are also high. We also stated that outlier stays, as well 
as providers with a large share of outlier payments, tend to have 
higher daily routine charges, which drive higher costs. We noted that 
we did not observe case-mix differences that would explain the 
significantly higher routine costs for facilities with a high share of 
outlier payments.
    Under the current outlier methodology, these high-cost facilities 
have necessitated substantial increases to the outlier threshold to 
maintain outlier payments at the 2 percent target. In the proposed 
rule, we explained that the significant increase to the outlier fixed 
dollar loss threshold under our current policy would make it more 
difficult for the majority of IPFs to receive outlier payments for 
treating Medicare beneficiaries whose care is exceptionally costly. We 
stated that we believe that establishing a policy to limit the impact 
to the outlier fixed dollar loss threshold amount from the small number 
of high-cost IPFs that we have identified in our analysis would better 
align with the outlier policy's core objective of protecting facilities 
from the financial risk of treating unusually expensive patients. We 
also stated our belief that the current concentration of outlier 
payments does not best serve the intended purpose of this policy and 
may inadvertently limit access to care for high-cost patients at 
facilities that cannot reach the higher threshold.
    In the proposed rule, we explained that we considered changes to 
limit the impact to the outlier fixed dollar loss threshold amount from 
high-cost IPFs for which outlier payments comprise an unusually large 
share of their total IPF PPS payments. We stated in the proposed rule 
that our analysis found that 47.8 percent of all simulated outlier 
payments were attributable to approximately 37 IPFs with more than 20 
percent outlier payments to total IPF PPS payments. We estimated that 
if we applied a 20-percent facility-level cap (that is, outlier 
payments for an IPF are less than or equal to 20 percent of the IPF's 
total IPF PPS payments, including outliers), the FY 2027 outlier fixed 
dollar loss threshold amount would be approximately $37,820, lower than 
what it would be under our current outlier policy and much closer to 
the FY 2026 outlier fixed dollar loss threshold amount of $39,360. We 
estimated that 40 more providers would receive payments under the 
outlier adjustment than under our current policy (increasing from 379 
providers to 419 providers), due to the lower outlier fixed dollar loss 
threshold that we proposed. Additionally, we estimated that 
approximately 1.9 percent of IPF stays would qualify for outlier 
payments, with an average outlier payment amount of approximately 
$1,012. We noted in the proposed rule that in comparison to the current 
outlier policy, applying a 20-percent facility-level cap on outlier 
payments would reduce the outlier fixed dollar loss threshold, 
resulting in outlier payments that would be expanded to a larger number 
of stays and providers. We stated that we also considered the potential 
impact of a facility-level cap on total outlier payments. We stated 
that we believe it would be appropriate to set a facility-level outlier 
cap at a percentage that protects the outlier fixed dollar loss 
threshold amount while limiting the number of IPFs that would be 
subject to the cap. Looking retrospectively at FY 2025 billing 
patterns, we estimated that around 3.6 percent of providers would be 
affected by a facility-level outlier cap at 20 percent. We estimated 
that a larger share of between 5 and 10 percent of IPFs would be 
impacted in a typical year by a 10 or 15 percent cap; however, a lower 
cap would also result in a lower outlier fixed dollar loss threshold. 
Conversely, we estimated that a smaller share of IPFs would be affected 
in a given year by a 25 or 30 percent cap (between 1 and 3 percent of 
IPFs), but this policy would require a higher outlier fixed dollar 
threshold amount. We refer readers to Table 3 in the FY 2027 IPF PPS 
proposed rule for a summary of the share of providers impacted at 
outlier cap levels from 10 to 30 percent (91 FR 17734).
    We stated in the proposed rule that we believe that a 20-percent 
facility-level outlier cap would strike an appropriate balance between 
protecting the outlier fixed dollar loss threshold amount and limiting 
the impact of the cap to only those IPFs with an unusually high share 
of outlier payments. Therefore, we proposed to establish a facility-
level cap on outlier payments beginning in FY 2027. Specifically, we 
proposed to limit total outlier payments to no more than 20 percent of 
a facility's total IPF PPS payments. Under this proposal, if an IPF 
exceeded the 20 percent facility-level cap, it would no longer receive 
an outlier payment for high-outlier cases but would receive the IPF PPS 
per diem payment. We solicited comments on the proposed cap policy as 
well as comments about setting the cap at 20 percent versus an 
alternative percentage.
    We proposed to codify this policy for the IPF PPS at Sec.  
412.424(d)(3)(i)(D) for discharges occurring in cost reporting periods 
beginning on or after October 1, 2026. We proposed to calculate and 
apply this cap on an interim basis on IPF PPS claims beginning in FY 
2027. Because outlier payments are finalized at cost report settlement, 
we proposed to apply this cap on an annual basis by calculating a 
facility's outlier percentage using a methodology that we detailed in 
the FY 2027 IPF PPS proposed rule (91 FR 17734 and 17735). We sought 
comment on the proposed implementation approach for interim payments as 
well as at cost report settlement.
    We also discussed in the proposed rule the possibility of exempting 
IPFs from this cap policy if they do not exceed a minimum threshold of 
annual stays. We stated that applying the cap only to facilities with 
more than 25 stays per year would result in a slightly higher outlier 
threshold of $37,880 (compared to $37,820 if the cap applies to all 
facilities) but would reduce the number of facilities subject to the 
cap (from approximately 2.7 percent of all IPFs to approximately 1.8 
percent) and potential payment adjustments. We sought comment on 
whether such a

[[Page 48532]]

minimum stay threshold would be appropriate and, if so, what the 
appropriate threshold should be.
    Under our proposed policy, we estimated that the outlier threshold 
for FY 2027 would be $37,820, which we previously noted would be lower 
than it would have been under our current outlier policy and much 
closer to the FY 2026 outlier fixed dollar loss threshold amount of 
$39,360. By moderating the threshold increase, we stated that we 
believed this proposal would make outlier payments accessible to a 
broader range of facilities treating high-cost patients, which we 
believe better aligns with the purpose of the IPF PPS outlier policy.
    Finally, in conjunction with this proposal, we solicited comments 
on the factors that contribute to higher costs at facilities that 
routinely receive an unusually high share of outlier payments. We 
stated that we were interested in understanding whether there are other 
factors for which the IPF PPS does not already adjust payment that 
could explain differences in patient resource use and costs among these 
IPFs, in accordance with Section 124 of the BBRA. We stated that we 
were particularly interested in understanding the following:
     What specific patient characteristics, clinical 
complexities, or treatment modalities drive higher costs at these 
facilities?
     To what extent do geographic factors, local labor market 
conditions, or real estate costs contribute to elevated routine costs?
     Do these facilities provide specialized services or treat 
patient populations that are not adequately reflected in the current 
IPF PPS payment adjustments?
     Are there structural changes to the IPF PPS facility 
adjustments or case-mix system that would more appropriately account 
for the notable cost differences across facilities?
     Are facilities incentivized to provide longer lengths of 
stay to receive outlier payments, particularly if there is bed 
capacity? If so, what is the impact for beneficiaries who are subject 
to a 190-day lifetime limit on IPF services? Could the proposed changes 
to the outlier policy, or potential further changes, reduce incentives 
for unnecessarily long lengths of stay?
     Do beneficiaries perceive differences in quality, 
outcomes, or value between higher-cost and lower-cost facilities?
    The following is a summary of the comments we received on the 
proposed 20 percent facility-level outlier cap and our responses.
    Comment: Several commenters supported the proposed outlier cap, 
stating that it is a good solution to the concentration of outlier 
payments among a small number of facilities. One of these commenters 
stated that this policy would increase the number of IPFs that qualify 
for outlier payments and noted that the purpose of the outlier policy 
should be to be a safety valve for unusually costly stays rather than a 
recurring financing mechanism for a limited number of providers. A 
commenter stated that the outlier cap strikes a good balance between 
preserving access and maintaining accountability and strengthens the 
IPF PPS by advancing payment accuracy, program integrity, and 
sustainability. This commenter appreciated that our proposal 
additionally projected how the outlier cap would affect the outlier 
threshold. In response to the comment solicitation regarding the 
factors that contribute to higher costs at facilities that routinely 
receive an unusually high share of outlier payments, commenters offered 
insights about costs related to adequate staffing, as well as 
challenges in post-discharge placement including shortages in community 
behavioral health capacity, supportive housing, substance use treatment 
services, and post-acute behavioral health resources.
    Response: We thank the commenters for their support and insights 
regarding the drivers of unusually high costs at IPFs. We agree about 
the importance of striking the appropriate balance between protecting 
access for unusually costly stays while ensuring the outlier threshold 
is set at a reasonable level that makes outlier payments available for 
more beneficiaries receiving care at IPFs across the country. As 
discussed in the following paragraphs, we are finalizing certain 
modifications to our proposed outlier cap in response to comments. We 
anticipate that these modifications will strike the appropriate balance 
between the goals we articulated in the proposed rule and the concerns 
that several commenters raised.
    In addition, we intend to perform additional analyses of the cost 
drivers and challenges that commenters highlighted, and we will take 
these comments into consideration to potentially inform future 
rulemaking.
    Comment: Some commenters requested that CMS monitor the potential 
effect of the cap on access to care and to evaluate whether certain 
tailored exemptions to the policy would be appropriate. Some commenters 
also requested that CMS consider whether the proposed 20 percent cap 
best addresses the concentration of outlier payments among a few 
facilities or whether another cap level would be appropriate. Other 
commenters who opposed the 20 percent cap stated that the process for 
developing this policy appeared to be arbitrary and requested that CMS 
do more analysis before finalizing it. Additionally, some commenters 
stated that their analysis found variation in the providers that would 
have reached the 20 percent cap from year to year, indicating the 
providers whose outlier payment would be capped would not be the same 
group of providers every year. Commenters stated that this instability 
in the pool of providers hitting the cap indicates that the proposed 
cap policy would not target providers with structurally higher costs.
    Response: We appreciate these comments regarding the basis for the 
20 percent cap. As we explained in the proposed rule, we analyzed the 
impact of different levels of caps on the percent of IPFs affected and 
on the outlier fixed dollar loss threshold. We found that a 20-percent 
facility-level outlier cap would strike an appropriate balance between 
protecting the outlier fixed dollar loss threshold amount and limiting 
the impact of the cap to only those IPFs with an unusually high share 
of outlier payments. Specifically, we noted that the proposed 20 
percent cap would result in an outlier fixed dollar loss threshold for 
FY 2027 that was much closer to the current FY 2026 outlier fixed 
dollar loss threshold, while only 3.9 percent of providers would be 
affected by the cap. As we discussed in the proposed rule, we also 
evaluated higher cap levels, including cap levels above 20 percent. 
While higher cap levels would reduce the number of providers affected 
by the policy, payment simulations indicated that they would have a 
correspondingly smaller effect on moderating growth in the fixed-dollar 
loss threshold amount. We explained in the proposed rule that we 
believe a 20-percent cap appropriately balances the objective of 
preserving access to outlier payments across a broader range of 
providers while limiting the policy's impact to a relatively small 
number of facilities with unusually high concentrations of outlier 
payments (91 FR 17734).
    We also appreciate the comments about the consistency of the pool 
of providers hitting the outlier cap over multiple years. We further 
analyzed IPF outlier payments by provider from FY 2023 through FY 2025 
to better understand whether or not providers would consistently exceed 
the proposed 20 percent outlier cap. We note that the proposed cap 
policy, which did not provide for any exclusions, would have

[[Page 48533]]

applied to all providers regardless of the number of annual IPF PPS 
stays. We found that providers with fewer stays would exceed the 
proposed 20 percent cap less consistently than providers with more 
stays. For example, 13 providers had greater than 20 percent outlier 
payments in FY 2025 and had 25 stays or fewer in that year; we found 
that only three of these providers would have exceeded 20 percent 
outliers in FY 2023 and FY 2024 as well. Similarly, among the nine 
providers that had greater than 20 percent outlier payments and between 
25 and 50 stays in FY 2025, only three would have exceeded 20 percent 
outliers in FY 2023 and FY 2024. There were 19 providers with greater 
than 20 percent outlier payments and 50 or more stays in FY 2025, and 
we found that seven of these providers would have exceeded 20 percent 
outliers in all three years.
    In response to the public comments, we are modifying our proposed 
outlier cap policy to apply to only providers with 50 or more stays per 
year. We find that applying the 20 percent cap to providers with 50 or 
more stays per year would impact 0.8 percent of providers in a typical 
year, as compared to 3.6 percent of providers under our proposed 
policy. At the same time, we estimate that if this policy were applied 
for FY 2027, the outlier fixed dollar loss threshold would be 
approximately $39,390, which is lower than what it would be in the 
absence of a cap, resulting in 157 more providers receiving outlier 
payments. Approximately 1.7 percent of IPF PPS stays would qualify for 
outlier payments with the average outlier payment being $19,054 per 
stay. As discussed in the following paragraphs, we are modifying the 
effective date of the proposed outlier cap policy to begin in FY 2028. 
We will continue monitoring claims and cost report data and take 
commenters' suggestions into consideration for future potential 
rulemaking.
    Comment: A few commenters who disagreed with the proposed outlier 
cap stated that more analysis is needed to determine why outlier 
payments are concentrated among a small number of providers. These 
commenters analyzed IPF claims data and concluded that their 
statistical modeling only explained a limited share of variation in 
outlier payment patterns. They found that facilities whose outlier 
payments would reach the 20 percent cap were more likely to treat 
patients with a comorbidity and were more likely to offer ECT, which 
they concluded indicated that these were facilities that were better 
equipped for more intensive treatments for patients with more complex 
needs. They also found that these facilities were more likely to be 
urban and to be teaching facilities and that variables like whether an 
IPF is a freestanding hospital or a unit and the IPF's wage index 
contributed more to variations in costs than patient characteristics 
did.
    Some commenters expressed concern that a 20 percent cap on outlier 
payments could impact IPFs' willingness to treat patients requiring 
longer stays and more resource-intensive treatment, limiting access to 
care. A commenter stated that an outlier cap, by reducing reimbursement 
for very costly cases, could result in shorter lengths of stay for 
Medicare beneficiaries and a reluctance on the part of IPFs to treat 
patients who need ECT treatment. A commenter stated that our impact 
analysis showed that facilities impacted by the cap tend to serve a 
higher percentage of patients who are disabled, are dually eligible for 
Medicare and Medicaid, whose primary diagnosis is schizophrenia or 
schizoaffective disorder, and whose stays are longer, and concluded 
that these facilities are safety-net providers, and that their high 
costs are not likely driven by high routine costs like labor, real 
estate, and overhead. Instead, this commenter and others stated that 
the long lengths of stay often leading to outlier payments are due to 
the unavailability of appropriate discharge options.
    Several commenters expressed concern that the effect of an outlier 
cap could incentivize IPFs whose outlier payments have been capped to 
turn away patients with high-cost needs or discharge patients 
prematurely, shifting costs for these patients' care to emergency rooms 
and increasing overall Medicare payments. One of these commenters 
recommended that we consider a higher cap of 25 to 30 percent to 
protect the outlier pool while preserving access at safety-net 
facilities, a minimum stay threshold to exempt low-volume facilities; 
add payment for various discharge pathways; and exempt facilities 
meeting certain safety-net criteria from the cap.
    Another commenter also suggested modifications or exemptions for 
providers treating disproportionate numbers of high acuity or safety-
net populations. Another suggested that CMS add modifications to the 
outlier cap policy to account for patient acuity, length-of-stay 
drivers outside provider control, and concentration of high-cost cases 
within certain facilities. Another commenter also stated that patients' 
stays may be extended while waiting for a bed to become available at an 
appropriate facility for discharge (like a state facility or a skilled 
nursing facility), and pointed out that a facility may therefore have 
more outlier payments not as a result of their own costs, but because 
of insufficient capacity at long-term care facilities in the area. A 
commenter who disagreed with the cap stated that the policy would 
create a disincentive for IPFs to treat high-acuity patients, impacting 
emergency rooms, law enforcement, families, and community crisis 
centers. This commenter requested CMS withdraw the proposal, phase in, 
or delay implementation of the cap and conduct ongoing monitoring, 
reporting, and impact analysis on a variety of facility and patient-
level characteristics. They also requested that CMS implement an 
exceptions process that would evaluate whether a facility's outlier 
payments reflect patient complexity or inappropriate billing or 
utilization.
    Response: We appreciate the commenters' concerns regarding the 
effect of any policy changes on access to care for Medicare 
beneficiaries. Protecting access to care for Medicare beneficiaries has 
been central to our development of this reform of the outlier policy. 
In response to these concerns, we are modifying the effective date of 
the final outlier cap policy. We believe it is appropriate to delay the 
implementation of this policy until FY 2028 (that is, October 1, 2027) 
to allow for IPFs that receive a high share of outlier payments to make 
appropriate adjustments to their cost structures and business practices 
to ensure that access to care is not disrupted because of changes in 
outlier policy. In addition, we intend to conduct additional analysis 
of the potential drivers of cost that commenters noted in their 
responses. While we are sensitive to concerns that a cap on outlier 
payments would affect certain high-cost facilities, the concentration 
of outlier payments among a few facilities and a declining share of 
stays accompanied by an increasing fixed-dollar loss threshold has a 
corresponding impact on access to care at IPFs nationwide. Accordingly, 
as we discuss later in this final rule, we are finalizing our proposal 
to cap outlier payments at the provider level in order to increase 
access to care at IPFs nationwide.
    We further note that commenters' concern about length of stay alone 
driving high outlier payments is not supported by the data. As we 
explained in the FY 2027 IPF PPS proposed rule (91 FR 17734) and 
earlier in this final rule, outlier stays tend to have higher daily 
routine charges, which drive

[[Page 48534]]

higher costs. Overall, these providers charge nearly twice as much per 
day as compared to the average ($6,000 vs. $2,600). We also note that 
as a per diem payment system, the IPF PPS inherently accounts for the 
cost impact of longer lengths of stay through higher IPF PPS payments.
    We appreciate the comments regarding patient acuity and commenters 
advocating for modifications or exemptions for providers treating 
disproportionate numbers of high acuity patients. However, we remind 
readers that the IPF PPS payment framework currently accounts for 
patient acuity as a driver of cost. The IPF PPS provides for payment 
adjustments for a variety of patient and facility-level characteristics 
that broadly recognize the impact of these factors on resource use for 
a stay. These include adjustments for age, DRG, comorbid conditions, 
and an additional payment per unit of ECT. We further note that in FY 
2025, we increased the ECT payment per treatment from $385.58 to 
$661.52 based on more recent cost information. Although commenters 
stated that IPFs receiving high outlier payments are more likely to 
offer ECT, we do not find that IPF PPS outlier payments are associated 
with the provision of ECT.
    We likewise considered the comments pertaining to safety net 
populations. We considered establishing a provider-specific exceptions 
process. However, we believe that such an approach would increase 
administrative burden for both providers and the agency, require 
individualized determinations that may vary from year to year, and 
reduce predictability in payment policy. We believe that a uniform 
policy applied according to objective criteria provides greater 
transparency and administrative simplicity while maintaining 
consistency across providers.
    We further note that our prior analyses have identified a 
relationship between per diem IPF costs and various measures of safety 
net status. At the inception of the IPF PPS, we explored the 
application of the disproportionate share hospital (DSH) variable used 
in other Medicare prospective payment systems (that is, the sum of the 
proportion of Medicare days of care provided to recipients of 
Supplemental Security Income and the proportion of the total days of 
care provided to Medicaid beneficiaries) for the IPF PPS. In the RY 
2005 IPF PPS final rule (69 FR 66958 through 66959), we explained that 
the DSH variable was highly significant in our cost regressions; 
however, we found that facilities with higher DSH had lower per diem 
costs. We noted that a study for the American Psychiatric Association 
also found the same results. We explained that the relationship of high 
DSH with lower costs could not be attributed to downward bias in the 
Medicaid proportion due to the IMD exclusion. We stated that this was 
because public psychiatric hospitals had lower costs on average than 
other types of IPFs. Therefore, we explained in the RY 2005 IPF PPS 
final rule that if we had proposed a DSH adjustment based on the 
regression analysis, IPFs with high DSH shares would have been paid 
lower per diem rates (69 FR 66958).
    More recently, in the FY 2025 IPF PPS proposed rule, we discussed 
and solicited comments about our analysis of the relationship between 
IPF per diem cost and our construction of a Medicare Safety Net Index 
(MSNI) for our IPF provider population (89 FR 23196 through 23198). 
Subsequently, in the FY 2025 IPF PPS final rule (89 FR 64641 through 
64642), we noted that the majority of commenters who responded to the 
RFI about a payment adjustment for MSNI opposed the addition of this 
adjustment factor under the construction presented in the proposed 
rule, either because of insufficient data to support the adjustment, 
because of the substantial decrease to the base rate, or because of the 
redistribution of resources away from IPFs with a low MSNI. We also 
stated that MedPAC recommended CMS conduct certain alternate analyses 
of the components of the MSNI.
    As we discussed in the FY 2027 IPF PPS proposed rule, we identified 
that providers with a high share of outliers tend to have patients who 
are more often disabled (66.3 percent vs. 57.1 percent) or dual-
eligible (68.1 percent vs. 60.8 percent). We intend to further study 
the relationship between safety net status and IPF costs, including 
outlier payments, and may consider proposing changes to the IPF PPS in 
the future, if appropriate.
    With respect to the comments regarding challenges finding post-
discharge placement, we note that the November 15, 2004 Inpatient 
Psychiatric Facility Prospective Payment System final rule (69 FR 
66952) explains that the IPF PPS does not have an administrative 
necessary days policy and does not provide payment for days that do not 
meet an active level of treatment. Only a physician can determine the 
need for continued hospitalization and or discharge. If the physician 
determines continued inpatient hospitalization is medically necessary, 
it is conveyed through a physician recertification. When a patient 
falls below an active level of care, the provider identifies the day as 
such on the claim, and it is not paid under the Inpatient Psychiatric 
Facility Prospective Payment System. Instead, the provider can bill, if 
applicable, Medicare Part B services.
    We also appreciate the comments regarding facility-level factors 
such as urbanicity, wage index, teaching status, and whether an IPF is 
unit-based or freestanding of cost as drivers of outlier payments. We 
note that aside from facility type (unit-based or freestanding), each 
of these facility-level factors is already accounted for in the IPF PPS 
and, accordingly, in the outlier policy. As we discuss earlier in this 
final rule, we are evaluating whether additional sources of data could 
potentially improve the accuracy of the IPF wage index in the future. 
We also intend to explore whether certain drivers of cost that 
commenters identified, such as staffing intensity, could help explain 
structural cost differences between unit-based and freestanding IPFs.
    We continue to analyze claims and cost report data to identify 
additional revisions to the IPF PPS that may improve the accuracy of 
the payment system in ways that are responsive to these commenters' 
concerns. As we have previously stated, the purpose of the outlier 
payment is to promote access to IPF care for those patients who require 
expensive care and to limit the financial risk of IPFs treating 
unusually costly patients.
    Comment: A commenter supported efforts to reduce the outlier 
threshold for all providers but was concerned that a 20 percent cap 
would cut legitimate outlier payments. They requested that in place of 
a cap; CMS instruct the Medicare Administrative Contractors to assess 
claims with high outlier payments to target providers with high outlier 
payments on a case-by-case basis. Another commenter who disagreed with 
the outlier cap also discussed program integrity regarding outlier 
payments and stated that in place of a facility-level cap, CMS should 
pursue remedies targeted toward post-payment reviews and documentation 
requirements of providers with high outlier payments.
    Response: We appreciate the comments regarding actions that CMS 
could take to ensure program integrity for IPF PPS outlier payments. 
While targeted audits, medical review, or other program integrity 
activities may be appropriate to address potential billing or 
documentation issues in individual cases, CMS does not believe they 
would address the broader payment policy concern identified in this 
rulemaking.

[[Page 48535]]

Specifically, the increasing concentration of outlier payments among a 
small number of providers contributes to growth in the fixed-dollar 
loss threshold amount, which affects access to outlier payments across 
the IPF PPS. Audits alone would not address this threshold-setting 
dynamic because they do not modify the methodology used to determine 
outlier payments prospectively. Our analysis indicates that the 
concentration of outlier payments among a small number of facilities is 
due to high fixed costs. In addition to the existing outlier 
reconciliation process, CMS continues to monitor IPFs and other 
providers for potential indicators of fraud, waste, and abuse and take 
appropriate action where necessary. In addition, we may consider 
changes to our instructions to the MACs in the future, if appropriate.
    Comment: A commenter requested that CMS adopt a forecasting error 
adjustment for the outlier threshold to ensure total payments meet 
projected targets.
    Response: We recognize that there can be differences between 
projected growth and actual growth of total payments. The IPF fixed 
dollar loss threshold is set prospectively, which means that the update 
relies on a mix of both historical data for part of the period for 
which the update is calculated and forecasted data for the remainder. 
Due to the uncertainty regarding future trends, forecast errors can be 
both positive and negative. For example, the forecast error for the IPF 
market basket has been both positive and negative during past years, 
and over longer periods of time the cumulative forecast has not 
deviated significantly from the historical measures. As we have 
previously stated, our longstanding methodology for updating the 
outlier fixed-loss threshold continues to rely on using the best 
available data to maintain outlier payments at 2 percent of total IPF 
PPS payments, and any deviations from this established approach are 
carefully considered based on specific data quality concerns rather 
than as standard practice. We will continue to monitor the IPF PPS 
outlier policy and propose the application of appropriate statistical 
methods when necessary to ensure the integrity of the outlier policy 
while maintaining the balance between protecting facilities from 
extraordinarily costly cases and ensuring adequacy of the Federal per 
diem base rate for non-outlier cases.
    Comment: Several commenters requested that CMS not implement the 
proposed outlier cap but maintain the FY 2026 outlier threshold of 
$39,360 for FY 2027 while conducting further analysis to determine the 
drivers of outlier payments.
    Response: In response to the suggestion that CMS hold the outlier 
threshold at $39,360 for FY 2027, we remind readers that our 
longstanding outlier policy uses the latest available data to target 
outlier payments at 2 percent. Our modeling based on the latest 
available FY 2025 claims and cost information indicates that the 
current outlier threshold would result in 2.1 percent outlier payments 
in FY 2027. Therefore, our analysis indicates that maintaining the 
current outlier threshold of $39,360 for FY 2027 would not be 
appropriate because it would not target outlier payments at 2 percent 
of total payments in FY 2027.
    Final Decision: After consideration of the public comments we 
received, we are finalizing our proposal, with modification, to 
implement a provider-level outlier cap. Specifically, we are finalizing 
our proposal to limit outlier payments to 20 percent of a facility's 
total IPF PPS payments. However, we are deferring the effective date of 
this policy until October 1, 2027 (FY 2028). Additionally, we are 
applying an exception to the outlier cap policy for facilities with 
fewer than 50 stays during the cost reporting year. We are codifying 
this policy for the IPF PPS at Sec.  412.424(d)(3)(i)(D) for discharges 
occurring in cost reporting periods beginning on or after October 1, 
2027.
    Under this policy, if an IPF exceeds the 20 percent facility-level 
cap, it will no longer receive an outlier payment for high-outlier 
cases. We will calculate and apply this cap on an interim basis on IPF 
PPS claims beginning in FY 2028. Because outlier payments are finalized 
at cost report settlement, we will apply this cap on an annual basis 
using the following methodology:
    Step 1: Determine whether the number of IPF PPS stays during the 
facility's cost reporting period is greater than or equal to 50.
    Step 2: Calculate the facility's total non-outlier payments (that 
is, IPF PPS payments excluding outlier payments) for all discharges 
occurring during the cost reporting year.
    Step 3: Divide the facility's total non-outlier payments by 80 
percent (0.8) to determine the maximum allowable total IPF PPS payment 
amount (including outlier payments and non-outlier payments).
    Step 4: Subtract the provider's maximum allowable total IPF PPS 
payment from its actual total IPF PPS payment amount. If the result of 
this calculation is greater than 0, then the facility's total outlier 
payments exceed 20 percent of its total IPF PPS payments.
    Step 5: If the facility's total outlier payments exceed the 20 
percent cap, reduce the outlier payment by the result of the 
calculation in Step 4.
    For example, if a facility has $10 million in total IPF PPS 
payments (excluding outliers) and would otherwise receive $3 million in 
outlier payments, the facility would have an actual total IPF PPS 
payment amount of $13 million. Following the formula in Step 3, the 
provider's maximum allowable total IPF PPS payment amount would be $10 
million/0.8 = $12.5 million. The facility's outlier payments would 
therefore be capped at $2.5 million (20 percent of $12.5 million).
    In addition, for FY 2027, we are finalizing our proposal to update 
the fixed dollar loss threshold amount used under the IPF PPS outlier 
policy. For this FY 2027 IPF PPS rulemaking, consistent with our 
longstanding practice, based on an analysis of the latest available 
data (the March 2026 update of FY 2025 IPF claims) and rate increases, 
we believe it is necessary to update the fixed dollar loss threshold 
amount to maintain an outlier percentage that equals 2 percent of total 
estimated IPF PPS payments. Based on an analysis of these updated data, 
we estimate that IPF outlier payments as a percentage of total 
estimated payments are approximately 2.0 percent in FY 2026. Therefore, 
we are finalizing an update to the outlier threshold amount to $40,750 
to maintain estimated outlier payments at 2 percent of total estimated 
aggregate IPF payments for FY 2027.
2. Update to IPF Cost-to-Charge Ratio Ceilings
    Under the IPF PPS, an outlier payment is made if an IPF's cost for 
a stay exceeds a fixed dollar loss threshold amount plus the IPF PPS 
amount. To establish an IPF's cost for a particular case, we multiply 
the IPF's reported charges on the discharge bill by its overall cost-
to-charge ratio (CCR). This approach to determining an IPF's cost is 
consistent with the approach used under the IPPS and other PPSs. In the 
RY 2004 IPPS final rule (68 FR 34494), we implemented changes to the 
IPPS policy used to determine CCRs for IPPS hospitals, because we 
became aware that payment vulnerabilities resulted in inappropriate 
outlier payments. Under the IPPS, we established a statistical measure 
of accuracy for CCRs to ensure that aberrant CCR data did not result in 
inappropriate outlier payments.
    As indicated in the RY 2005 IPF PPS final rule (69 FR 66961), we 
believe that the IPF outlier policy is susceptible to

[[Page 48536]]

the same payment vulnerabilities as the IPPS; therefore, we adopted a 
method to ensure the statistical accuracy of CCRs under the IPF PPS. 
Specifically, we adopted the following procedure in the RY 2005 IPF PPS 
final rule:
     Calculated two national ceilings, one for IPFs located in 
rural areas and one for IPFs located in urban areas.
     Computed the ceilings by first calculating the national 
average and the standard deviation of the CCR for both urban and rural 
IPFs using the most recent CCRs entered in the most recent Provider 
Specific File (PSF) available.
    For FY 2027, we proposed to continue following this methodology. To 
determine the final rural and urban ceilings, we multiplied each of the 
standard deviations by 3 and added the result to the appropriate 
national CCR average (either rural or urban). The final upper threshold 
CCR for IPFs in FY 2027 is 2.4179 for rural IPFs and 1.8699 for urban 
IPFs, based on current CBSA-based geographic designations. If an IPF's 
CCR is above the applicable ceiling, the ratio is considered 
statistically inaccurate, and we assign the appropriate national 
(either rural or urban) median CCR to the IPF.
    We apply the national median CCRs to the following situations:
     New IPFs that have not yet submitted their first Medicare 
cost report. We continue to use these national median CCRs until the 
facility's actual CCR can be computed using the first tentatively or 
final settled cost report.
     IPFs whose overall CCR is in excess of three standard 
deviations above the corresponding national geometric mean (that is, 
above the ceiling).
     Other IPFs for which the Medicare Administrative 
Contractor (MAC) obtains inaccurate or incomplete data with which to 
calculate a CCR.
    We proposed to update the FY 2027 national median and ceiling CCRs 
for urban and rural IPFs based on the CCRs entered in the latest 
available IPF PPS PSF. We did not receive any comments on this 
proposal, and we are finalizing it as proposed.
    Specifically, for FY 2027, to be used in each of the three 
situations listed previously, using the most recent CCRs entered in the 
CY 2025 PSF, we provide an estimated national median CCR of 0.5720 for 
rural IPFs and a national median CCR of 0.4200 for urban IPFs. These 
calculations are based on the IPF's location (either urban or rural) 
using the current CBSA-based geographic designations. A complete 
discussion regarding the national median CCRs appears in the RY 2005 
IPF PPS final rule (69 FR 66961 through 66964).

V. Inpatient Psychiatric Facility Quality Reporting Program

A. Background and Statutory Authority

    The IPF Quality Reporting Program is authorized by section 
1886(s)(4) of the Act, and it applies to psychiatric hospitals and 
psychiatric units paid by Medicare under the IPF PPS (see section II.A. 
of this final rule for a detailed discussion of entities covered under 
the IPF PPS). We refer readers to the FY 2019 IPF PPS final rule (83 FR 
38589) for a discussion of the background and statutory authority of 
the IPF Quality Reporting Program. We have codified procedural 
requirements and reconsideration and appeals procedures for IPF Quality 
Reporting Program decisions in our regulations at 42 CFR 412.433 and 
412.434. Consistent with previous IPF Quality Reporting Program 
regulations, we refer to both inpatient psychiatric hospitals and 
psychiatric units as ``inpatient psychiatric facilities'' (at times, 
simply ``facilities'' where the context is clear) or ``IPFs.'' This 
usage follows the terminology in our IPF PPS regulations at Sec.  
412.402.
    Section 4125(b)(1) of the Consolidated Appropriations Act of 2023 
(CAA, 2023) amended section 1886(s)(4)(E) of the Act, which requires 
IPFs participating in the IPF Quality Reporting Program to collect and 
submit to the Secretary certain standardized patient assessment data, 
using a standardized patient assessment instrument (PAI) developed by 
the Secretary, for RY 2028 (FY 2028) and each subsequent rate year. We 
discuss policies related to the implementation of the IPF-PAI in 
section IV.C. of this final rule.

B. Quality Measures in the IPF Quality Reporting Program

1. Removal of the Alcohol Use Brief Intervention Provided or Offered 
and Alcohol Use Brief Intervention (SUB-2/2a) Measure
    In the FY 2027 IPF PPS proposed rule, we proposed to remove the 
Alcohol Use Brief Intervention Provided or Offered (SUB-2) and subset 
Alcohol Use Brief Intervention (SUB-2a) measure from the IPF Quality 
Reporting Program beginning with the calendar year (CY) 2026 reporting 
period/FY 2028 payment determination and subsequent years under measure 
removal factor 8--that is, that the costs associated with a measure 
outweigh the benefit of its continued use in the program--and measure 
removal factor 3--that is, that the measure can be replaced by a more 
broadly applicable measure. In the proposed rule, we described how the 
IPF Quality Reporting Program measure set currently includes two 
measures that address alcohol use disorders: SUB-2/2a, described above, 
and Alcohol and Other Drug Use Disorder Treatment Provided or Offered 
at Discharge (SUB-3) and the subset Alcohol and Other Drug Use Disorder 
Treatment at Discharge (SUB-3a). SUB-2/2a assesses whether patients who 
screened positive for unhealthy alcohol use received or refused a brief 
alcohol use intervention during their IPF stay (80 FR 46699 through 
46701). SUB-3/3a assesses whether patients who are identified as having 
an alcohol or drug use disorder are offered a referral or prescription 
for treatment at discharge. SUB-2/2a was adopted into the IPF Quality 
Reporting Program beginning with the CY 2016 reporting period (80 FR 
46699 through 46701), and SUB-3/3a was adopted in the program beginning 
with the CY 2017 reporting period (81 FR 57239 through 57241). Both 
measures require facilities to submit chart-abstracted measure data for 
a sample of IPF patient records, in accordance with established 
sampling policies (80 FR 46717 through 46719).
    The IPF Quality Reporting Program strives to maintain a balanced 
set of meaningful quality measures with minimal burden. To meet that 
goal, we evaluated both SUB-2/2a and SUB-3/3a to ensure that the IPF 
Quality Reporting Program measure set is responsive to our objectives 
for improving quality of care and minimizing burden for facilities. We 
conducted an internal analysis of performance data for SUB-2 and SUB-3 
to determine performance gaps and greater potential for improvement. 
Mean and median scores for the most recent three years of performance 
for both measures show room for improvement--median scores on SUB-2 and 
SUB-3 ranged from 0.73 to 0.79 between 2023 and 2025 \7\--but we 
observed no substantial difference in performance between the two 
measures.
---------------------------------------------------------------------------

    \7\ CMS internal analysis.
---------------------------------------------------------------------------

    While SUB-2 and SUB-3 are similar measures, with similar 
performance rates, SUB-3/3a captures a broader patient population than 
SUB-2/2a--specifically, it includes patients who have screened positive 
for either alcohol use disorder or substance use disorder while SUB-2/
2a only includes patients who have screened positive for alcohol use 
disorder. Therefore, we proposed to remove the SUB-2/2a measure to 
reduce reporting burden associated with the IPF Quality Reporting 
Program. We estimated that this would reduce the collection of 
information burden for IPFs by $13,110,832 per year and

[[Page 48537]]

eliminate CMS program costs for oversight of the measure. We stated 
that the costs of keeping the SUB-2/2a measure in the IPF Quality 
Reporting Program exceed the benefits of retaining the measure. The 
SUB-2/2a measure was also recently retired from The Joint Commission's 
ORYX[supreg] requirements effective CY 2026.
    We proposed to remove the SUB-2/2 measure from the IPF Quality 
Reporting measure to reduce burden on facilities for collecting and 
reporting these data and because the measure can be replaced by SUB-3/
3a, a more broadly applicable measure. However, we stated that we 
continue to believe that brief alcohol use interventions are valuable 
and encourage IPFs to continue to offer this intervention to patients 
for whom it is appropriate, should we finalize the removal of the SUB-
2/2a measure from the program. We also recognize that the goals and 
priorities of an IPF stay vary among patients based on their clinical 
needs as well as personal preferences. By proposing to remove this 
measure, we intended for IPF clinicians to collaborate with patients to 
prioritize the types of activities and areas of focus that best support 
individual patient treatment goals while reducing the burden associated 
with the current collection of measures related to substance use 
treatment. While both SUB-2/2a and SUB-3/3a address alcohol use and 
show similar performance trends, the retention of SUB-3/3a in the 
program addresses both alcohol and substance use disorder treatment in 
the IPF setting while reducing the burden of having two measures 
addressing the same condition.
    We received public comments on this proposal.
    Comment: Many commenters supported removing SUB-2/2a, agreeing with 
CMS' rationale that it is duplicative of SUB-3/3a and other reporting 
expectations, and stated that its burden outweighs its usefulness in 
the program. Commenters stated that removal would streamline reporting 
and stated that reducing administrative burden would allow facilities 
to redirect time and resources to increase focus on patient care 
activities.
    Response: We thank the commenters for their support and agree that 
the removal of this measure will alleviate reporting burden for 
facilities and may allow facilities to spend more time on patient care 
or quality improvement. We appreciate that they agree with our 
rationale for measure removal, that the costs associated with a measure 
outweigh the benefit of its continued use in the program, and that the 
measure can be replaced by a more broadly applicable measure, SUB-3/3a.
    Comment: Several commenters supported the removal of the measure, 
stating that performance has plateaued, topped out, or remained 
stagnant over three years, showing the measure is no longer driving 
meaningful improvement. A few commenters stated that SUB-2/2a has 
limited clinical usefulness, is not necessary for the IPF Quality 
Reporting Program, does not provide meaningful insight into IPF quality 
of care, and no longer provides sufficient clinical value. Some 
commenters stated that these concerns also apply to the SUB-3/3a 
measure.
    Response: We thank the commenters for their support for removing 
SUB-2/2a and acknowledge that the consistent performance of this 
measure suggests it is no longer driving clinical quality improvement. 
We disagree with commenters that the same concerns regarding measure 
performance and clinical usefulness equally apply to the SUB-3/3a 
because we believe that it is still important and clinically meaningful 
for IPFs to address both alcohol use and substance use in the IPF 
setting. We are removing the SUB-2/2a measure from the IPF Quality 
Reporting Program because retaining SUB-3/3a in the program addresses 
both alcohol and substance use disorder treatment in the IPF setting 
while reducing the burden of having two measures addressing alcohol 
use.
    Comment: A commenter supported removal stating that many state 
hospitals treat patients whose length of stay excludes them from SUB-2/
2a patient population, making the measure's burden exceed its benefit 
for these facilities.
    Response: We thank the commenter for their support and acknowledge 
that IPFs treating patients with stays greater than 120 days may find 
this measure less beneficial because it does not apply to much of their 
patient population.
    Comment: Many commenters supported removing SUB-2/2a, stating that 
SUB-3/3a covers a broader patient population, preserves substance use 
disorder treatment reporting at discharge, or is duplicative of SUB-2/
2a.
    Response: We thank the commenters for their support and agree that 
SUB-3/3a covers a broader patient population and preserves the focus on 
treatment for substance use disorder.
    Comment: Several commenters recommended removing SUB-3/3a stating 
that performance has plateaued, The Joint Commission announced it will 
stop maintaining related specifications after 2026, and there is burden 
associated with reporting it.
    Response: Because substance use disorder has negative effects on 
treatment outcomes and patient wellbeing it remains appropriate to 
retain a measure related to treatment of substance use disorder in the 
IPF Quality Reporting Program. We recognize that performance on SUB-3/
3a has plateaued but are retaining the measure to ensure the IPF 
Quality Reporting Program continues to focus on this important 
condition. We acknowledge that The Joint Commission has announced it 
will no longer include SUB-3/3a as a requirement for data submission to 
ORYX; we understand this to be a part of The Joint Commission's overall 
transition away from chart-abstracted measures and will ensure that the 
specifications remain appropriate for reporting. We understand 
commenters' concerns regarding the burden of reporting this measure and 
continue to evaluate potential lower burden options to collect data 
regarding substance use treatment in the IPF setting.
    Comment: Some commenters expressed concern about removal of 
measures from the IPF Quality Reporting Program, including the removal 
of SUB-2/2a, stating that quality measures have multiple benefits, 
including driving quality improvement and providing information to the 
public. Some commenters stated that alcohol use, substance use, tobacco 
use, and related interventions are directly tied to behavioral health 
outcomes, physical and mental health, comprehensive patient care, and 
treatment quality in psychiatric settings.
    Response: We agree that alcohol use, substance use, tobacco use, 
and related interventions are important components of behavioral health 
care and overall treatment quality. IPFs are responsible for providing 
clinically appropriate care regardless of whether treatment for these 
conditions is measured in the IPF Quality Reporting Program. We 
proposed removal of SUB-2/2a to maintain a balanced measure set with 
minimal burden and note that SUB-3/3a captures a broader patient 
population to continue supporting the program's objectives.
    Comment: A commenter stated that the SUB-2/2a performance should 
not justify removal because 21 to 27 percent of patients who screened 
positive still did not receive or refuse a brief intervention, and the 
plateau supports intensified focus and technical assistance rather than 
removing the measure and eliminating accountability. This commenter 
cited evidence

[[Page 48538]]

supporting the effectiveness of hospital-based Screening, Brief 
Intervention, Referral to Treatment (SBIRT) approach.
    Response: We appreciate this feedback. We note that SUB-2/2a and 
SUB-3/3a performance showed similar room for improvement. By retaining 
SUB-3/3a we expect that we will retain a focus on treatment for 
substance use disorders, including alcohol use disorder, while reducing 
data collection and reporting burden. While providing technical 
assistance to improve measure performance is outside the scope of the 
IPF Quality Reporting Program, we agree with commenters regarding the 
effectiveness of SBIRT interventions and note that the Substance Abuse 
and Mental Health Services Administration (SAMHSA) has information 
regarding systems-level implementation of SBIRT which provides 
resources to support health systems in addressing substance use 
disorder including through referrals.\8\

    Comment: A few commenters who opposed removal stated that SUB-3/3a 
may not provide equivalent alcohol-specific coverage, stated that 
offering intervention during treatment is different from offering help 
at or after discharge, and that patients may be less likely to receive 
brief interventions through referral at discharge.
    Response: Clinicians should use their clinical judgment to 
determine what intervention or referral is most appropriate for each 
patient, based on the patient's clinical needs and preferences, both 
during the stay and at discharge. For that reason, and to reduce 
burden, we are removing SUB-2/2a while retaining SUB-3/3a, which 
captures a broader patient population and continues to support 
substance use disorder treatment at discharge.
    Comment: Some commenters stated that co-occurring substance use 
disorders are common among patients with inpatient psychiatric stays, 
alcohol use disorder is highly prevalent, and alcohol or tobacco use is 
associated with readmissions, treatment resistance, mortality, long-
term recovery concerns, and missed treatment opportunities. Some 
commenters stated that screening, brief intervention, motivational 
interviewing, and personalized referral to treatment can improve 
insight, post-discharge engagement, overall wellness, and 
rehospitalization or readmission outcomes.
    Response: We agree that co-occurring substance use disorders are 
common in the IPF population and that there are many available 
evidence-based treatments that can support recovery and other outcomes. 
Removing SUB-2/2a does not change the responsibility of IPFs to deliver 
high-quality care, and we encourage IPFs to continue to use clinical 
judgment and shared decision-making to determine which interventions 
are appropriate for each patient. We are removing the measure to reduce 
burden while retaining SUB-3/3a, which continues to address substance 
use disorder treatment at discharge and captures a broader patient 
population.
    Comment: A few commenters acknowledged burden, duplication, 
limitations, or accountability concerns with the current measures, but 
recommended that CMS provide clear justification or alternative 
accountability methods, and reconsider or delay removal until improved 
replacement measures, technical assistance, or adequate accountability 
measures are operational.
    Response: We appreciate the concern and recognize commenters' 
interest in preserving accountability while addressing burden. At this 
time, removing SUB-2/2a is appropriate as the measure's costs outweigh 
its benefits and SUB-3/3a remains in the program to continue publicly 
reporting substance use-related interventions. We continuously review 
the IPF Quality Reporting Program measure set to maintain a balanced 
set of meaningful quality measures with minimal burden, and we may 
consider future IPF-PAI or measure additions on topics related to 
substance use and treatment as program needs and priorities evolve.
    Comment: A commenter opposed removal, stating concerns that removal 
could introduce or reinforce diagnostic upcoding and make patients who 
need substance use related counseling less likely to receive proper 
care.
    Response: The removal of SUB-2/2a will not impact an IPF's 
obligation to code accurately or to provide medically necessary, high-
quality care consistent with the patient's clinical needs and Medicare 
requirements. We encourage IPFs to continue to use appropriate clinical 
judgment and shared decision-making in determining whether substance 
use related counseling or other interventions are warranted.
    Comment: A commenter recommended that CMS consider alcohol use 
assessment for all new admissions because of safety risks, including 
potential contraband access during transport or admission, and stated 
that future safety-related measures or IPF-PAI assessments should 
acknowledge the importance of early detection of alcohol use.
    Response: We thank the commenter for this recommendation and will 
consider it as we continue to evaluate measures for the IPF Quality 
Reporting Program.
    Final Decision: After consideration of the comments received, we 
are finalizing the removal of the SUB-2/2a measure as proposed.
2. Removal of the Tobacco Use Treatment Provided or Offered at 
Discharge (TOB-3/3a) Measure
    We proposed to remove the Tobacco Use Treatment Provided or Offered 
at Discharge (TOB-3) and subset Tobacco Use Treatment at Discharge 
(TOB-3a) measure from the IPF Quality Reporting Program beginning with 
the CY 2026 reporting period/FY 2028 payment determination and 
subsequent years under measure removal factor 8, the costs associated 
with a measure outweigh the benefit of its continued use in the 
program. TOB-3 assesses whether patients were offered evidence-based 
outpatient counseling and offered a prescription for FDA-approved 
cessation medication upon discharge. TOB-3a identifies the subset of 
those IPF patients who received a referral and received a prescription 
for FDA-approved cessation medication upon discharge. This measure 
began to be used in the IPF Quality Reporting Program with the CY 2016 
reporting period (80 FR 46696 through 46699), and requires facilities 
to submit chart-abstracted measure data on a sample of IPF patient 
records, in accordance with established sampling policies (80 FR 46717 
through 46719). Our internal analysis of performance data for TOB-3 
found median scores on TOB-3 from 0.58 to 0.63 between 2023 and 2025, 
remaining stable over time, with no indication of improvement. This 
suggests that this measure is no longer driving facilities to increase 
their offerings of these interventions.
    We stated in the proposed rule that the IPF Quality Reporting 
Program strives to maintain a balanced set of meaningful quality 
measures with minimal burden. Removal of this measure would reduce 
collection of information burden for IPFs by $13,110,832 \9\ per year 
and eliminate CMS program costs for oversight of the measure. We stated 
we recognize that smoking and other forms of tobacco use are common 
among IPF patients 10 11 and

[[Page 48539]]

it would remain appropriate for IPFs to offer evidence-based tobacco 
cessation counseling and FDA-approved cessation medication to patients 
for whom it is clinically indicated even if we finalized the proposal 
to remove the TOB-3/3a measure from the program. We noted the TOB-3/3a 
measure was also recently retired from The Joint Commission's 
ORYX[supreg] requirements effective CY 2026.\12\ Given the burden, we 
believe the costs of keeping the measure in the IPF Quality Reporting 
Program now exceed the benefits of retaining the measure.

    We received public comments on this proposal.
    Comment: Many commenters supported removing TOB-3/3a, with some 
stating that the measure creates administrative burden without 
providing sufficient clinical value; the cost outweighs the benefit; 
the measure no longer drives meaningful improvement as demonstrated by 
consistent measure performance; and that reducing duplicative or low-
value reporting would allow IPFs to focus more time and resources on 
higher-value activities such as direct patient care and clinically 
meaningful quality improvement.
    Response: We thank the commenters for their support and agree that 
removing the TOB-3/3a measure will reduce administrative burden which 
will allow focus on patient care and other quality improvement efforts.
    Comment: A few commenters supported removal and stated that IPF 
stays are short and focused on mental health concerns or acute 
psychiatric stabilization. These commenters stated that acute mental 
health crises are often not the most appropriate time to address 
tobacco use and that more routine or stable care settings may be more 
appropriate intervention points.
    Response: We thank the commenters for their support and appreciate 
their perspective on the scope of the inpatient psychiatric stay. 
However, we encourage IPFs to continue to deliver clinically 
appropriate, patient-centered care, which may include lifestyle 
interventions, including tobacco and nicotine cessation, when those are 
appropriate for the individual patient.
    Comment: A few commenters supported the removal of the measure and 
stated that discharging patients with nicotine replacement therapy may 
entail clinical risks when cessation programs are inaccessible, 
community follow-up support is limited, IPF staff cannot ensure 
continued tobacco cessation support, and patients may return to tobacco 
use after discharge.
    Response: We acknowledge the commenters' feedback. The Department 
of Health and Human Services has long recognized tobacco use as a 
leading preventable cause of disease, disability, and death in the 
United States and has supported evidence-based efforts to reduce 
tobacco use across health care settings. Evidence demonstrates that 
tobacco cessation interventions, including counseling and FDA-approved 
cessation medications, are safe and effective and can improve health 
outcomes, including among individuals with behavioral health 
conditions.13 14 We acknowledge the commenters' concern 
about the risks of using nicotine replacement therapy while resuming 
tobacco or other nicotine use, but we disagree that the risks outweigh 
the potential benefits to patients of reducing or eliminating tobacco 
use. We encourage IPFs to continue to provide clinically appropriate 
tobacco cessation counseling or medication when indicated and when 
aligned with the patient's goals for treatment.

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

    Comment: A few commenters expressed support for removing the TOB-3/
3a measure, stating that it does not adequately address the current 
patient population, other nicotine delivery systems, expanded access to 
medications, patient interest in tobacco cessation at discharge, or the 
need to measure tobacco use and treatment received at the facility 
rather than discharge practices. A few commenters noted limitations in 
the current measure, including the inability to track patient refusal, 
the prevalence of workarounds for hospitals, lack of data for 
improvement, and that the measure tracks facility processes instead of 
patient outcomes. A few commenters recommended alternative ways to 
measure tobacco use and treatment received at the facility or other 
pathways for reducing nicotine use. A commenter recommended that the 
measure could be reconsidered and updated in the future.
    Response: We thank the commenters for identifying their concerns 
with TOB-3/3a and for their suggestions regarding other dimensions of 
tobacco and nicotine use and cessation treatment that could be 
appropriate for quality measures. We will continue to evaluate ways to 
address tobacco and nicotine use in future IPF-PAI or measure 
development.
    Comment: A few commenters supported the removal of the measure but 
stated that IPFs should continue evidence-based tobacco cessation 
counseling, education about available resources, care coordination, 
smoking cessation counseling, cessation medications, and other 
appropriate interventions when clinically indicated or aligned with 
patient-centered treatment planning.
    Response: We thank the commenters for the support and agree that 
IPFs should continue to provide appropriate interventions around 
tobacco and nicotine cessation when clinically indicated.
    Comment: Several commenters opposed the removal of this measure, 
stating that alcohol use, substance use, and tobacco use are closely 
tied to outcomes, and that appropriate screenings and cessation 
interventions are part of comprehensive patient care, improving 
behavioral health outcomes. Several commenters stated that tobacco use, 
alcohol use, and co-occurring substance use disorders are common among 
patients in IPFs, that tobacco and alcohol use are linked to mortality 
and worse outcomes, and that tobacco use can complicate psychiatric 
treatment, affect psychiatric medications, and worsen behavioral health 
symptoms or recovery. Several commenters cited evidence supporting 
alcohol and tobacco interventions and treatment during hospitalization 
or at discharge; they stated these interventions can improve outcomes, 
reduce readmissions or costs, improve quit rates, support recovery, or 
improve mood and quality of life.
    Response: We agree that these are important issues in the care of 
IPF patients. However, removing TOB-3/3a does not change an IPFs' 
ability to

[[Page 48540]]

provide clinically appropriate tobacco, alcohol, or substance use 
interventions when indicated, and we encourage IPFs to continue to use 
clinical judgment in developing care plans that address each patient's 
individual needs.
    Comment: Many commenters opposed removal stating that quality 
measures support accountability, transparency, visibility into patient 
outcomes and facility performance, data on interventions offered or 
received, and incentives for health care professionals or facilities to 
address tobacco dependence, tobacco cessation, and substance use 
treatment.
    Response: We note that we proposed to remove the TOB-3/3a measure 
because the costs associated with reporting measure data outweighs the 
measure's benefits in the IPF Quality Reporting Program, and we are 
removing the measure to reduce reporting burden on IPFs. The TOB-3/3a 
measure requires facilities to submit chart-abstracted measure data on 
a sample of IPF patient records. Because chart-abstracted is a resource 
intensive process the TOB-3/3a burden is costly to maintain in the 
program. We continue to recognize the value of accountability and 
transparency and encourage IPFs to provide clinically appropriate 
tobacco cessation counseling and medication when indicated, even in the 
absence of a publicly reported measure.
    Comment: Several commenters recommended that CMS reconsider 
removal, clearly justify removal, consider alternative metrics or 
approaches, or delay removal until adequate replacement or improved 
measures are operational.
    Response: In deciding to propose to remove the TOB-3/3a measure, we 
carefully evaluated the IPF Quality Reporting Program's measure to 
ensure that we maintain a balanced set of meaningful quality measures 
with minimal burden. As part of this evaluation, we determined that the 
costs associated with the TOB-3/3a measure outweigh the benefits of 
continuing to maintain the measure in the IPF Quality Reporting 
Program. That is, that the costs associated with annual reporting on 
this chart-abstracted measure were not proportional to the benefits of 
keeping the measure in the program. We will continue to evaluate ways 
to address tobacco and nicotine use in future IPF-PAI or measure 
development. We thank the commenters for their recommendations related 
to potential replacements for the TOB-3/3a measure.
    Comment: A few commenters stated that plateaued or low performance 
does not justify removal. They expressed concern that TOB-3/3a 
performance remains low and recommended that stable performance should 
lead CMS to intensify focus, maintain incentives, or improve 
performance rather than remove the measure. A commenter recommended 
that CMS consider performance improvement rather than removal, 
including targeted technical assistance, provider education, or 
modified measure specifications to move performance above the plateau 
before eliminating accountability entirely.
    Response: Although TOB-3/3a performance showed room for improvement 
we note that annual reporting of this measure, which is accomplished 
through chart abstraction of a sample of patients, is time-consuming 
for IPFs and that, as other commenters described, it does not fully 
address current tobacco use patterns. We refer readers to section 
VI.C.3 of this final rule for details on the estimated decrease in 
information collection burden for IPFs by removing this measure. We 
note that the SBIRT approach (described in more detail in response to 
comments on the removal of the SUB-2/2a measure in section V.B.1. of 
this final rule) can be used for addressing nicotine use.\15\ We 
continue to encourage IPFs to provide clinically appropriate 
interventions for patients who use nicotine. Removing this measure 
reduces burden now while allowing us to consider alternatives in future 
rulemaking if a more effective or less burdensome measure can better 
address this topic.

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

    Comment: A few commenters acknowledged administrative burden, 
duplication, or limitations in current measures, but stated that 
removal without an improved measure could reduce clinician attention to 
tobacco use or lose useful accountability while failing to address 
patient refusal, patient progress, and the realities of inpatient 
treatment. A commenter expressed concern that removing TOB-3/3a could 
reduce the number of clinicians asking about tobacco use and 
recommended that CMS develop a better measure or revise the current 
measure to provide better data. A few commenters recommended replacing 
TOB-3/3a with the Tobacco Use Screening and Cessation Intervention 
measure and stated that it would support tobacco use treatment 
reporting, encourage IPFs to offer cessation interventions, and improve 
outcomes for people with behavioral health conditions. A commenter 
stated that CMS should not remove TOB-3/3a before a replacement or 
bridge is operational, and that the proposed IPF-PAI does not currently 
include tobacco use assessment items and would not be fully implemented 
for several years, creating a gap in addressing tobacco use.
    Response: We appreciate these comments. We are removing TOB-3/3a to 
reduce burden in the IPF Quality Reporting Program, while encouraging 
IPFs to continue to address tobacco use when clinically appropriate. 
Although it is reasonable to expect that the IPF Quality Reporting 
Program influences clinical quality and care--by, for example, 
emphasizing certain care processes or outcomes--clinical judgment and 
shared decision-making with patients inform treatment planning. We also 
remain open to potential future IPF-PAI items or better, less 
burdensome measures on the topic of tobacco and nicotine use.
    Comment: A commenter opposed removal stating that removing TOB-3/3a 
could introduce or reinforce diagnostic upcoding and make patients 
needing substance abuse counseling less likely to receive proper care.
    Response: The removal of TOB-3/3a does not impact IPFs' obligation 
to code accurately and to provide medically appropriate, high-quality 
care consistent with the patient's clinical needs and Medicare 
requirements. We encourage IPFs to continue to use appropriate clinical 
judgment and shared decision-making in determining whether tobacco 
cessation counseling or other interventions are warranted, regardless 
of whether this specific measure remains in the program.
    In addition, as discussed above, we recognize the prevalence of 
nicotine use among patients treated in IPFs, and the importance of 
interventions and treatment. Therefore, we also solicited comment on 
alternative ways to address this topic, potentially through the 
proposed standardized patient assessment, the IPF Patient Assessment 
Instrument (IPF-PAI), described in Section IV.C. of this final rule. We 
invited comments on how to assess nicotine use (for example, mode of 
delivery, frequency of use, level of dependence) as well as treatments 
and interventions for nicotine use (for example, type of treatment or 
intervention, timing of delivery).
    We received public comments.
    Comment: A commenter recommended aligning tobacco use tracking with 
Draft United States Core Data for Interoperability (USCDI) v7 to

[[Page 48541]]

support consistency and data sharing across healthcare settings, and 
advocated for well-vetted, standardized tools that are accessible to 
EHR developers. A commenter recommended that future tobacco use 
treatment measures include digital and web-based tobacco cessation 
interventions so IPFs can be reimbursed when referring patients to 
these programs at discharge. A commenter stated that pay-for-
performance could provide a stronger incentive than pay-for-reporting 
for improving tobacco-related metrics, and encouraged us to support 
community programs that help reduce tobacco use after IPF patients are 
discharged. A commenter recommended that CMS not add assessment items 
on nicotine use to the IPF-PAI.
    Response: We thank the commenters for these recommendations and 
will consider these in future rulemaking.
    Final Decision: After consideration of the comments received, we 
are finalizing the removal of the TOB-3/3a measure as proposed.

C. Implementation of the Inpatient Psychiatric Facilities Patient 
Assessment Instrument (IPF-PAI)

1. Background
    As required by section 1886(s)(4)(E) of the Act, IPFs must submit 
such data with respect to admissions and discharges of an individual 
from the IPF, and more frequently as the Secretary determines 
appropriate. For IPFs to meet this new data collection and reporting 
requirement for FY 2028 and each subsequent year, the Secretary must 
implement a standardized PAI that collects data with respect to the 
following categories: functional status; cognitive function and mental 
status; special services, treatments, and interventions for psychiatric 
conditions; medical conditions and comorbidities; impairments; and 
other categories as determined appropriate by the Secretary.\16\ To 
enable meaningful comparison of the patient assessment data across all 
IPFs submitting data, the IPF-PAI must be standardized. Each IPF must 
administer the same assessment instrument with identical questions, 
response options, standards and definitions.\17\
---------------------------------------------------------------------------

    \16\ Sections 1886(s)(4)(E)(ii)(I) through 1886(s)(4)(E)(ii)(VI) 
of the Act.
    \17\ We note that while the data elements of the IPF-PAI would 
be standardized--that is, identical question and identical sets of 
response options--standardization does not extend to the order of 
the data elements within the instrument.
---------------------------------------------------------------------------

    In the FY 2025 IPF PPS proposed rule, we solicited comments for 
consideration in the development of a standardized assessment 
instrument (89 FR 23200 through 23204). Specifically, we solicited 
comment on the following considerations: a set of principles for 
selecting standardized patient assessment data elements \18\ (to 
include overall clinical relevance; interoperable exchange to 
facilitate care coordination during transitions in care; ability to 
describe medical complexity and risk factors that can inform both 
payment and quality; and scientific reliability and validity, including 
general consensus agreement for its usability); any patient assessments 
recommended for use in the IPF-PAI on clinical topics related to the 
data categories required by statute; implementation considerations; and 
the relationship between the IPF-PAI and the IPF Quality Reporting 
Program, such as use of IPF-PAI data in program measures. In the FY 
2026 IPF PPS proposed rule, we further solicited comments for 
consideration with respect to potential interoperable exchange of IPF-
PAI data using the HL7[supreg] Fast Healthcare Interoperability 
Resources[supreg] (FHIR[supreg]) \19\ standards (90 FR 18520 through 
18523).
---------------------------------------------------------------------------

    \18\ While this RFI discussed ``data elements,'' we note that we 
have transitioned to using the term ``assessment items'' to refer to 
the components of the standardized patient assessment.

Seven International (HL7) and the use does not constitute

2. Considerations in Selecting Assessment Items and Related Data 
Elements for the IPF-PAI
    Between 2023 and 2025, CMS and its contractors engaged in a multi-
stage process to conceptualize and scope a new, statutorily mandated 
PAI for the IPF setting that included: identifying key clinical topic 
areas within the broad CAA, 2023 data categories, identifying and 
evaluating candidate assessment items within those topic areas, and 
conducting formative (alpha) and field (beta) testing on those 
candidate assessment items. This process also included engagement with 
subject matter experts, clinicians and administrators at IPFs, and 
individuals who have experience as patients in an IPF setting, as well 
as guidance from interoperability experts on how to structure 
assessment items and their related data elements so that the patient-
level data that are collected by the IPF-PAI would be interoperable and 
aligned with current health IT standards.
    We first identified key topics and candidate assessment items that 
aligned with the data categories identified in section 
1886(s)(4)(E)(ii) of the Act by reviewing clinical practice guidelines; 
papers and reports from academic journals, government agencies, and 
other organizations; clinical assessments related to inpatient 
psychiatric care; and existing standardized patient assessment data 
elements used in other provider settings. We reviewed the United States 
Core Data for Interoperability (USCDI) \20\ and United States Core Data 
for Interoperability (USCDI)+ Behavioral Health \21\ data elements to 
understand the interoperable data landscape for inpatient acute care as 
well as outpatient and ambulatory behavioral health care. We also 
considered comments submitted in response to the requests for 
information in the FY 2025 IPF PPS final rule (89 FR 64645 through 89 
FR 64650) described above. Candidate assessment items were reviewed for 
relevance and feasibility for the IPF setting, as well as the potential 
to reflect resource use or quality of care. An initial list of 
candidate assessment items selected from our review was advanced to 
subsequent phases of testing and expert input. Formative (alpha) 
testing was conducted to evaluate the feasibility and face validity of 
candidate assessment items in the IPF setting. Field (beta) testing was 
conducted to assess inter-rater reliability (IRR),\22\ estimate burden, 
and to confirm content validity and feasibility in the IPF setting. 
More information about the design and results of the testing is 
available in the IPF-PAI Testing Report, available under IPF-PAI 
Development and Testing resources at https://qualitynet.cms.gov/ipf/PAI. In addition, a technical expert panel (TEP) was convened by the 
IPF-PAI development contractor to give input on the extent to which 
topics of assessment items were clinically relevant to patient care in 
IPFs, likely to inform CMS' understanding of resource use or costs of 
care, and considered feasible and relatively low burden to collect. The 
TEP included clinicians and administrators at IPFs, behavioral health 
clinicians, academic researchers, health information technology 
specialists, and individuals who have experience as patients in an IPF 
setting. More information on the two meetings of the TEP held during 
IPF-PAI development is available under IPF-PAI Development and Testing 
resources at https://qualitynet.cms.gov/ipf/PAI.

3. Implementation of the Inpatient Psychiatric Facilities Patient 
Assessment Instrument (IPF-PAI) in the IPF Quality Reporting Program
a. IPF-PAI
    In the FY 2027 IPF PPS proposed rule, we proposed to implement the 
IPF-PAI as the assessment instrument for the submission of standardized 
patient assessment data as required by section 1886(s)(4)(E)(ii) of the 
Act for all patients aged 18 and older. This initial version of the 
IPF-PAI is intended to meet our statutory obligation to collect 
standardized patient assessment data on each of the statutorily-
delineated data categories while being mindful of reporting burden on 
IPFs; we purposefully selected a minimal set of assessment items to 
propose. We reiterate that the IPF Quality Reporting Program strives to 
maintain a minimal set of requirements while meeting statutory 
requirements and encouraging quality through transparency and public 
reporting. To that end, the IPF-PAI proposed in the FY 2027 IPF PPS 
proposed rule was also intended to establish a structure and processes 
for data collection and submission that we could modify or expand 
through future rulemaking, to stay responsive to priorities of IPF 
quality and payment. We stated that future enhancements may include the 
addition, removal, or changes of assessment items, but also that we 
anticipated using results and feedback from the proposed IPF-PAI to 
propose revisions or improvements to policies that will increase 
utility or reduce burden of the IPF-PAI for patients and IPFs.
    We proposed that IPFs paid under the IPF PPS be required to 
complete the IPF-PAI for all patients aged 18 and older. Assessment 
items would be administered at admission and discharge, except where 
specified in the proposals. Later in this section, we discuss the 
standardized patient assessment items and related data elements that 
were proposed for the initial version of the IPF-PAI. We refer readers 
to section V.C.4. of this final rule for more information on the method 
and schedule for data submission, as well as compliance thresholds for 
annual payment determination under the IPF Quality Reporting Program.
    We acknowledged that this new requirement of the IPF Quality 
Reporting Program may impact workflow and increase administrative 
burden, especially early in the implementation of the IPF-PAI as IPFs 
learn about and become familiar with the assessment and work to 
integrate it into their workflows. We proposed that the assessment 
items discussed in section IV.C.3.b of the FY 2027 IPF PPS proposed 
rule would be collected at admission and discharge. In the proposed 
rule, we estimated that completing both assessments for a patient would 
take 14.7 minutes, and that most administrative and clinical data on 
the IPF-PAI would be available in the patient's medical record as part 
of routine medical record keeping practices. We refer readers to 
section VI.C.3. of this final rule for discussion of our revised 
estimated costs associated with the collection of the IPF-PAI based on 
this final rule.
    We proposed to codify the IPF-PAI as part of the IPF Quality 
Reporting Program at Sec.  412.433(a) and (d) by adding ``standardized 
patient assessment data'' in the description of the statutory authority 
and as a type of data that IPFs that participate in the IPF Quality 
Reporting Program must submit to CMS.
    We received public comments on this proposal.
    Comment: Many commenters supported the proposal to adopt the IPF-
PAI into the IPF Quality Reporting Program based on its potential to 
provide comparable data across IPFs, support care coordination, and 
facilitate more consistent data collection to improve patient care as 
well as to

[[Page 48544]]

inform future quality measurement and policy development.
    Response: We thank the commenters for their support and agree that 
collecting standardized patient assessment data across IPFs will 
support the IPF PPS and the IPF Quality Reporting Program and will 
create infrastructure that has the potential to improve interoperable 
data exchange.
    Comment: Several commenters stated that the IPF-PAI, as proposed, 
is focused on administrative data rather than clinical assessment, does 
not fully capture clinically meaningful information or outcomes and is 
not aligned with inpatient psychiatric practice. A commenter further 
stated that the proposed IPF-PAI is not clinically meaningful, and 
would add burden without improving treatment planning, psychiatric 
hospital quality, or mental health outcome measurement. A few 
commenters expressed concern that requiring a standardized assessment 
for all patients may oversimplify complex mental health conditions, 
with the practical effect of constraining independent clinical judgment 
and undermining the inherently individualized psychiatric evaluation 
process.
    Response: We do not agree that the IPF-PAI is primarily 
administrative nor misaligned with inpatient psychiatric practice. 
While the IPF-PAI does include administrative items, these are limited 
to the items necessary for record matching and database management. The 
instrument was designed as an initial set of standardized items that 
includes statutorily-mandated and clinically relevant information about 
patient complexity and resource use, and is not intended to replace 
clinical assessment, intake, or treatment planning. We note that we are 
implementing the IPF-PAI to meet the CAA, 2023 requirement to collect 
standardized patient assessment data on each of the statutorily-
delineated data categories. While there are many more types of clinical 
information we considered for the IPF-PAI, and will continue to 
consider for future rulemaking, for the initial rollout of the IPF-PAI 
we strove to minimize reporting burden on IPFs. As to the assessment 
items we ultimately proposed, the TEP, which included behavioral health 
clinicians and staff from IPFs, endorsed assessment items in the 
statutorily mandated categories as clinically meaningful and 
appropriate for admission, discharge, or both. Quantitative and 
qualitative evidence from the 16 IPFs and 51 IPF staff included in the 
field (beta) testing supports that these assessment items are 
clinically meaningful, feasible to complete in routine admission and 
discharge workflows, and useful for understanding patient complexity, 
resource use, and care planning. We agree with commenters that the IPF-
PAI should not constrain individualized psychiatric evaluation or 
function as a diagnostic instrument. We expect that clinicians will 
continue to exercise judgment in determining diagnosis, treatment, and 
the level of care needed for individual patients.
    Comment: Many commenters stated that the IPF-PAI, as proposed, does 
not meet the clinical or methodological standards necessary to fulfill 
the statutory mandate of the CAA, 2023. For example, some commenters 
stated that the data collection for the IPF-PAI would not be 
sufficiently detailed or valid to be used in determining payment rates 
for the IPF PPS. A few commenters stated that the IPF-PAI as proposed 
fails to meet CMS' stated objectives in developing a patient assessment 
instrument regarding clinical relevance, validity, feasibility, and 
ability to inform resource intensity.
    Response: We maintain that the IPF-PAI could support future payment 
policy and enable comparison of IPF data across IPFs. We discuss each 
of the assessment items in more detail in section V.C.3.b. We note that 
the proposed instrument was developed through a multi-stage process 
which included a review of clinical practice guidelines, an 
environmental scan of existing standardized assessment items in 
behavioral health settings or in CMS quality reporting programs, an RFI 
in the FY 2025 IPF PPS proposed rule (89 FR 23200 through 23204), and 
continual engagement with IPFs, clinicians, vendors, health IT experts, 
and individuals with experience as patients in the IPF setting. We 
evaluated candidate items for relevance and feasibility in the IPF 
settings, as well as the potential to reflect resource use, which 
corresponds to the purposes described in the CAA, 2023 requiring 
assessment data which enable comparison of assessment data across all 
IPFs and which could be taken into account for potential future 
revisions to the IPF PPS methodology for determining payment rates. We 
evaluated the candidate assessment items through formative (alpha) 
testing to evaluate the feasibility and face validity of each item. 
Following formative (alpha) testing, feedback was gathered through two 
meetings of the TEP, which was comprised of clinicians and 
administrators at IPFs, behavioral health clinicians, academic 
researchers, health IT specialists, and individuals who have experience 
as patients in an IPF setting. Narrative input and voting during 
meetings of the TEP also support that candidate items selected for the 
IPF-PAI were viewed as clinically useful and appropriate for admission, 
discharge, or both, with alignment to the statutory categories, and 
relatively low-burden collection. In the Fall 2025 meetings of the TEP, 
at least two-thirds of TEP members responded ``Strongly Agree'' or 
``Agree'' to including each of the proposed assessment items on the 
IPF-PAI. Quantitative and qualitative evidence from the 16 IPFs and 51 
IPF staff included in the field (beta) testing supports that these 
assessment items are clinically meaningful and thus relevant, feasible 
to complete in routine admission and discharge workflows, and 
sufficiently detailed to be useful for understanding patient 
complexity, resource use, and care planning. We also intend to use 
results and feedback based on implementation of the IPF-PAI to propose 
revisions or improvements to policies that will increase utility or 
reduce burden of the IPF-PAI (91 FR 17739).
    Comment: Several commenters stated that implementation of the IPF-
PAI would impose administrative, operational, financial, and workflow 
burdens, including additional staff time and diversion of resources 
away from patient care. Several commenters also stated that the 
substantial costs and burden associated with the proposal would not be 
matched by proportional benefit.
    Response: We recognize that the IPF-PAI will require staff time and 
workflow changes, especially early in implementation, which is why the 
IPF-PAI was developed to minimize reporting burden on IPFs by 
leveraging data already assessed in existing workflows and available in 
the patient's treatment record while IPFs gain experience collecting 
and reporting IPF-PAI data. As stated at the end of this section, we 
are finalizing several modifications to the IPF-PAI reporting 
requirements to further reduce burden, as discussed in sections V.C.3. 
and V.C.4. of this final rule, and have revised our burden estimate as 
discussed in section VI.C. of this final rule. We will also provide 
guidance and training resources intended to support the initial 
implementation (91 FR 17739).
    Comment: Several commenters stated that the proposed IPF-PAI 
duplicates information already collected through existing assessments, 
reporting requirements, or accreditation activities. Many commenters 
requested that CMS streamline the instrument and eliminate

[[Page 48545]]

assessment items that duplicate or overlap with other CMS reporting 
requirements.
    Response: We acknowledge that the IPF-PAI was developed to leverage 
data already assessed in existing workflows and available in the 
patient's treatment record to the greatest extent feasible to minimize 
the need for IPFs to collect new data. We acknowledge that some 
information may overlap with accreditation requirements or current 
measures for some patient populations (for example, Medicare patients), 
but we maintain that collecting this information for all patients aged 
18 and older through the IPF-PAI will provide more accurate information 
regarding resource use and may support the development of future 
quality measures. We will consider the recommendation to streamline the 
instrument and reduce or eliminate overlap in data collection in future 
rulemaking.
    Comment: A few commenters stated that IPFs may face significant 
implementation challenges related to EHR modifications, HL7[supreg] 
FHIR[supreg] integration, vendor readiness, training, and workflow 
redesign, in the proposed timeframe, especially IPFs with fewer 
resources. A few commenters stated that workflow and system changes 
would require sufficient lead time for facilities to operationalize the 
IPF-PAI consistently and reliably, including modifying systems, 
training staff, testing workflows, validating data, and resolving 
vendor or technical issues before payment impacts begin. A commenter 
stated that implementation challenges would be heightened by behavioral 
healthcare facilities' lower EHR adoption rates and limited 
interoperable EHR capability. A few commenters recommended additional 
support to address operational readiness and infrastructure limitations 
related to health IT.
    Response: We appreciate these comments and recognize that 
implementation will require time, training, and workflow changes which 
will vary across IPFs, including for IPFs with fewer resources and IPFs 
without EHRs. We are committed to supporting IPF-PAI implementation 
through the provision of technical guidance, implementation guides, 
webinars, listserv updates, and a help desk. We note that IPFs may 
submit IPF-PAI data to CMS using a free, CMS-developed web application 
called the Patient Assessment Reporting Interoperability Tool (PARIT). 
This method for data submission, described more in section V.C.4. of 
this final rule, provides an option for IPFs to submit IPF-PAI data 
other than the FHIR[supreg] APIs.
    Comment: Many commenters recommended that CMS delay implementation 
of the IPF-PAI, return the instrument to development and testing, and 
allow additional time before mandatory reporting or payment impacts 
begin. Many commenters recommended that CMS engage clinicians, 
researchers, interested parties, and policymakers in further 
development of the IPF-PAI. A commenter recommended that interested 
parties throughout engagement should include frontline staff who 
complete documentation. A few commenters further recommended that CMS 
delay payment-related impacts. Several commenters requested non-
punitive transition periods, voluntary reporting periods, or other 
implementation flexibilities while IPFs and vendors prepare to 
operationalize the assessment.
    Response: Based on the comments, in an effort to provide more time 
for IPFs and their EHR vendors to integrate the requirements for the 
IPF-PAI into their workflows and technical resources, we are modifying 
the timelines for mandatory reporting, including adding a voluntary 
reporting period, and modifying data completeness thresholds that would 
impact payment determination under the IPF Quality Reporting Program, 
as further discussed in section V.C.4. of this final rule. Regarding 
engagement with experts and interested parties, as we described in the 
proposal rule, we developed the IPF-PAI through a multi-stage, multi-
interested party process that included engagement with subject matter 
experts, researchers, clinicians and administrators at IPFs, 
individuals with experience as patients in an IPF setting, 
interoperability experts, and a technical expert panel, and we also 
solicited public comment through FY 2025 and FY 2026 rulemaking to 
inform development of the instrument. The alpha (formative) and beta 
(field) testing both occurred with IPF staff, with the beta test 
including 51 IPF staff who would be responsible for collecting PAI data 
after finalization. We plan to continue to engage interested parties, 
including IPF clinicians and staff, to support the implementation of 
the IPF-PAI and potential changes that would occur through future 
rulemaking.
    Comment: A few commenters recommended that CMS or interested 
parties work with the Congress to change the requirements of the CAA, 
2023, to better align them with the inpatient psychiatric setting.
    Response: We thank the commenters for their recommendations. We 
maintain that the assessment items proposed for the IPF-PAI, which meet 
the categories required by the CAA, 2023, are relevant to the 
psychiatric inpatient setting and contribute to an understanding of 
resource intensity. We will continue to incorporate feedback from 
interested parties to support possible refinements to the IPF-PAI that 
would occur through future rulemaking.
    Comment: A commenter recommended that CMS conduct a formal impact 
assessment, including an evaluation of effects on rural and resource-
limited IPFs.
    Response: We recognize that the IPF-PAI requirement will have 
impacts for rural and resource-limited IPFs. We plan to provide 
implementation support in the form of trainings, webinars, listserv 
announcements, and a help desk that will be available to all IPFs. In 
addition, we will provide a free web application (91 FR 17745) that 
allows IPFs to submit IPF-PAI data without an EHR, a vendor, or changes 
to their health IT. We intend this resource to mitigate the impact of 
this new requirement on IPFs with fewer resources. We refer readers to 
section V.C.4. of this final rule for more information on the PARIT, 
the free web application.
    Comment: A few commenters recommended limiting the IPF-PAI to 
Medicare patients at first, with a commenter recommending that CMS 
begin with Medicare Fee-for-Service (FFS) and later add Medicare 
Advantage beneficiaries, to minimize burden and phase implementation.
    Response: We appreciate these comments and the need to phase 
implementation to minimize burden, which is why we are finalizing 
several modifications to reduce reporting burden. With these 
modifications, we think the benefits outweigh the burden of collecting 
data on all adult IPF patients regardless of payer types. We note that 
standardized data collection will allow us to gain useful information 
on resource use and quality. Therefore, we are requiring mandatory 
collection of the IPF-PAI for IPF patients aged 18 and older beginning 
July 1, 2028; in section V.C.4. of this final rule, we address 
modifications to the timelines for mandatory reporting and payment 
impacts.
    Comment: Many commenters expressed concern that CMS discussed 
potential refinement or modification to the IPF-PAI that would be done 
in future rulemaking, stating that changing program requirements are 
challenging for IPFs.
    Response: Similar to our approach to the IPF Quality Reporting 
Program measure set, we intend to monitor IPF-

[[Page 48546]]

PAI data and feedback from interested parties and may propose revisions 
to the instrument as needs and priorities evolve. We intend to provide 
adequate time and implementation guidance for any IPF Quality Reporting 
Program changes, including the IPF-PAI.
    Comment: A commenter recommended that CMS meet the statutory 
requirement for data collection with a patient assessment instrument 
not through the proposed IPF-PAI, but by using existing data that are 
collected through quality measures in the IPF Quality Reporting 
Program. Another commenter stated that while CMS must comply with the 
statute, CMS retains substantial discretion over the content of the 
instrument, the form and manner of submission, the compliance 
threshold, and the payment penalty tied to data reporting through the 
IPF Quality Reporting Program.
    Response: While we agree that we have substantial discretion over 
the instrument and the form, manner, and timing of data collection, 
existing data collections do not cover the full range of categories 
required by the CAA, 2023. In section V.C.4. of this final rule, we 
address modifications to the timelines for mandatory reporting, 
compliance thresholds, and payment impacts.
    Comment: A commenter stated that the CAA, 2023 does not specify 
that the IPF-PAI must be completed for all patients.
    Response: We maintain that collecting this information for all 
patients aged 18 and older through the IPF-PAI will provide more 
accurate information regarding resource use which can be used to inform 
payment rates for IPFs, consistent with the statutorily defined 
purposes for data collection under CAA, 2023. Accordingly, at this 
time, we are finalizing policies to require mandatory collection of the 
IPF-PAI for all patients aged 18 and older beginning July 1, 2028, and 
that--as discussed in section V.C.4.b. of this final rule--IPFs will 
need to complete 100 percent of the required IPF-PAI assessment items 
(that is, completeness requirement) on 50 percent of the IPF-PAIs 
submitted to meet the IPF Quality Reporting Program's IPF-PAI 
requirement (that is, compliance threshold) for the applicable annual 
payment determination. Beginning with the CY 2030 reporting period 
impacting the FY 2032 payment determination, the compliance threshold 
will increase to 70 percent. See section V.C.4. of this final rule, for 
additional information on modifications to the timelines for mandatory 
reporting and compliance thresholds.
    Comment: A commenter stated that CMS has not provided sufficient 
clarity regarding how IPF-PAI data will be used in future payment and 
quality measurement programs and recommended that CMS provide this 
information as well as time and flexibility around implementation to 
support successful adoption, while minimizing unintended disruptions to 
patient care.
    Response: We have developed the IPF-PAI to meet the uses described 
in the statute, that is, to enable comparison of the assessment data 
across IPFs, and to be taken into consideration when implementing 
revisions to the IPF PPS payment methodology. In section V.C.4. of this 
final rule, we address modifications to the timelines for mandatory 
reporting and payment impacts.
    Comment: A commenter stated support for the direction of the 
proposal because of statements CMS made about the IPF-PAI supporting 
interoperability.
    Response: We thank the commenter for their support and agree that 
there is value in promoting interoperability in healthcare.
    Final Decision: After consideration of the comments received, we 
are finalizing the proposal to adopt the IPF-PAI into the IPF Quality 
Reporting Program.
    Additionally, we solicited comment on the proposed age requirement 
for the IPF-PAI of 18 years and older, specifically the potential 
inclusion of adolescents in the population for the IPF-PAI. We were 
interested in feedback on any specific guardrails or sensitivities CMS 
should consider with the potential inclusion of adolescents, or 
specific assessment items that would not be appropriate for this 
population.
    We received public comments on this proposal.
    Comment: A few commenters supported the proposal to require the 
IPF-PAI be submitted for patients aged 18 years and older. One of these 
commenters stated that requiring the IPF-PAI for adolescents would 
negatively impact their admission experience by diverting staff 
attention. Another commenter supported the proposed aged 18 and older, 
but encouraged CMS to consider differences in care, treatment, and 
outcomes across adult age groups by analyzing stratified data.
    Response: We appreciate the commenters' support for this proposal, 
and acknowledge the recommendation to explore differences between adult 
age groups when IPF-PAI are received.
    Comment: A commenter recommended that CMS require the IPF-PAI also 
be submitted for adolescents to ensure quality care for that 
population. A commenter recommended that CMS develop a comparable 
instrument for pediatric populations enrolled in Medicare. This 
commenter stated that it is important because many of the pediatric or 
adolescent patients enrolled in Medicare qualify due to end-stage renal 
disease, which can pose additional care needs.
    Response: We thank the commenters for their recommendations. During 
the development of the IPF-PAI, we received feedback from the TEP that 
CMS should develop policies around the assessment that are responsive 
to the unique needs of distinct patient groups, including adolescents. 
In feedback on assessment items, however, the TEP discussed how the 
tools and assessments that are appropriate for adolescents sometimes 
differ from those for adults. Because of these concerns, this initial 
version of the IPF-PAI was developed with assessment items that are 
appropriate for use in adult patients--that is, we did not include 
adolescent-specific items or test general items in the adolescent 
population.
b. Assessment Items for the IPF-PAI
    In the FY 2027 IPF PPS proposed rule, we proposed that the IPF-PAI 
would collect data related to the five statutory data categories 
specified in section 1886(s)(4)(E)(ii) of the Act and fulfill the 
requirements of section 4125(b) of the CAA, 2023 for a standardized 
assessment instrument (see Table 5). In the FY 2025 IPF PPS proposed 
rule (89 FR 23200 through 23204) we issued a Request for Information 
(RFI) to solicit public input to inform the development of the IPF-PAI. 
In this RFI, we noted that goals for the IPF-PAI include improving the 
quality of care in IPFs and improving the accuracy of the IPF PPS. As 
provided by section 1886(s)(6) of the Act, added by section 4125(b) of 
the CAA, 2023, data collected through the IPF-PAI may be considered in 
future revisions to the methodology for determining the IPF PPS 
payment.
    In the proposed rule, we explained that standardized assessment 
items generally take the form of a question or instructional text that 
is followed by a set of response options. For example, the assessment 
item Speech Clarity would contain instructional text ``Select best 
description of speech pattern,'' and three response options: 0. Clear 
speech--distinct intelligible words; 1. Unclear speech--slurred or 
mumbled words; 2. No speech--absence of spoken words. Responses to 
assessment items can also take the form of structured numeric or text 
input, such as the responses given to Admission Date or

[[Page 48547]]

Patient Last Name. The proposed assessment items are standardized in 
the sense that all IPFs will be assessing patients using the same 
assessment items--that is, the same question or instructions and 
response options. In the proposals of assessment items to include in 
the IPF-PAI, we referred to the name of the assessment item. The 
complete assessment items, including instructional text and response 
options, are shown together on the IPF-PAI Item Set, available under 
IPF-PAI Resources at https://qualitynet.cms.gov/ipf/PAI. The IPF-PAI 
Item Set is a PDF document that shows the proposed assessment items 
displayed like a questionnaire. In order to support consistency in the 
administration of the IPF-PAI, as we have done for assessment 
instruments used in post-acute care settings, we stated that we will 
provide IPFs with a detailed reference manual that will provide 
additional guidance. A draft of the IPF-PAI Guidance Manual is 
available under IPF-PAI Resources at https://qualitynet.cms.gov/ipf/PAI.
    We proposed to include items for each of the five data categories 
required by statute in the IPF-PAI assessment. In addition, we proposed 
an additional category of administrative items. The proposed 
administrative items were determined appropriate by the Secretary and 
are necessary for record matching and database management. Table 5 
lists the proposed IPF-PAI assessment items by category. We referred 
readers to the Admission and Discharge forms that contained the 
proposed assessment items of the IPF-PAI are available under IPF-PAI 
Resources at https://qualitynet.cms.gov/ipf/PAI. For additional 
information on the testing process and the testing results in further 
details, we referred readers to the IPF-PAI Testing Report, available 
under IPF-PAI Development and Testing resources at https://qualitynet.cms.gov/ipf/PAI.
[GRAPHIC] [TIFF OMITTED] TR31JY26.027

    Evidence from field (beta) testing and engagement with experts and 
interested parties support these proposed assessment items as meeting 
our goals for the IPF-PAI, as stated in prior rulemaking (89 FR 23200 
through 23204): clinically relevant to patients in IPFs; standardized 
and interoperable; capturing medical complexity and risk factors that 
can inform payment and quality; and reliable and valid, with consensus 
agreement for usability (89 FR 23200 through 23204). To determine the 
clinical relevance to patients in IPFs and the ability of assessment 
items to assess medical complexity and risk factors that would inform 
payment and quality, we sought and summarized input through the RFI in 
the FY 2025 IPF PPS proposed and final rules (89 FR 64642 through 
64649). Building on that feedback we reviewed potential assessment 
items with CMS Medical Officers and engaged with clinicians through a 
TEP. To ensure that the assessment items allowed data to be recorded in 
a standardized format we evaluated the inter-rater-reliability (IRR) of 
each of the items as part of our field (beta) testing. High IRR scores 
show that the data are likely to be standardized across different 
raters at different IPFs. We also evaluated each assessment item in the 
field (beta) test for feasibility. Information about the TEP's input on 
each assessment item is included in the following subsections. 
Information about field (beta) test results for IRR and feasibility is 
included in Table 6.
    In the FY 2027 IPF PPS proposed rule, we noted that the IPF-PAI was 
developed and would be implemented in a way to support interoperable 
exchange of data. The standardized assessment items and response 
options are intended to yield comparable data across IPFs. The 
assessment items would be managed centrally in CMS' Data Element 
Library (DEL),\23\ enabling consistency in usage across versions or 
updates. Each assessment item is represented as a machine-readable data 
element with a stable identifier and metadata, such as definition, 
datatype, and permissible values. The DEL would assign LOINC \24\ and 
SNOMED \25\ codes to questions and response options, where possible; 
LOINC and SNOMED are widely-used terminology standards for clinical 
data that support consistent meaning across systems.

i. IPF-PAI Functional Status Category
    Section 1886(s)(4)(E)(i)(I) of the Act requires the inclusion of 
patient assessment data with respect to functional status, such as 
mobility and self-care. In the FY 2027 IPF PPS proposed rule, we 
proposed the assessment item Mobility: Chair/Bed-to-Chair Transfer for 
the Functional Status category of the IPF-PAI. This assessment item 
evaluates the patient's physical ability to move around, one of the 
basic activities of daily living. Specifically, the proposed assessment

[[Page 48548]]

item assesses the patient's ability to transfer to and from a bed to a 
chair (or wheelchair). For patients who do not complete this activity 
independently, the level of assistance required would need to be 
recorded. This information would be recorded by selecting the patient's 
functional status from the options provided. The instructional text and 
response options are included in the IPF-PAI Item Set, available under 
IPF-PAI Resources at https://qualitynet.cms.gov/ipf/PAI. Additionally, 
detailed instructions for administration would be provided through 
training and the IPF-PAI Guidance Manual, the draft of which is 
available under IPF-PAI Resources at https://qualitynet.cms.gov/ipf/PAI. For results of inter-rater reliability (IRR) and feasibility from 
field (beta) testing, see Table 6. Most TEP members (78 percent) 
responded Strongly Agree or Agree to including the Mobility assessment 
item on the IPF-PAI.
ii. IPF-PAI Cognitive Function and Mental Status Category
    Section 1886(s)(4)(E)(i)(II) of the Act requires the inclusion of 
patient assessment data with respect to cognitive function, such as the 
ability to express ideas and to understand, and mental status, such as 
depression and dementia. In the FY 2027 IPF PPS proposed rule, we 
proposed the assessment item Suicide Screening for the Cognitive 
Function and Mental Status category of the IPF-PAI. We note that we do 
not consider suicide-related thoughts and behaviors to be related to 
cognitive impairment. Rather, we understand mental status to encompass 
a wide range of cognition, orientation, mood, and decision-making 
capacities, including thought content. In our review of IPFs' core 
clinical assessment practice, the mental status exam, we identified 
screening for suicidal thoughts and behaviors to be an important 
clinical topic with relevance to quality of care and resource use.
    The assessment item evaluates whether and with what method a 
patient was screened for suicide risk. This information would be 
recorded by indicating that a patient was screened with a standardized 
tool, screened through clinical assessment, or not screened, in the 
case that the patient declined or was unable to respond. This 
assessment item, including instructional text and response options, is 
shown on the IPF-PAI Item Set, available under IPF-PAI Resources at 
https://qualitynet.cms.gov/ipf/PAI. Additionally, detailed instructions 
for administration would be provided through training and the IPF-PAI 
Guidance Manual, the draft of which is available under IPF-PAI 
Development and Testing resources at https://qualitynet.cms.gov/ipf/PAI. For results of IRR and feasibility from field (beta) testing, see 
Table 6. All TEP members (100 percent) responded Strongly Agree or 
Agree to including a Suicide Screening assessment item on the proposed 
IPF-PAI. After the field (beta) test and receiving TEP input, we 
revised this assessment item based on further input from individuals 
who have experience as patients in an IPF, clinical subject matter 
experts, and assessment item developers. We believe the proposed 
assessment item included in the IPF-PAI is more feasible to implement 
than the version used in testing.
iii. IPF-PAI Special Services, Treatments, and Interventions for 
Psychiatric Conditions Category
    Section 1886(s)(4)(E)(i)(III) of the Act requires the inclusion of 
patient assessment data with respect to special services, treatments, 
and interventions for psychiatric conditions. In the FY 2027 IPF PPS 
proposed rule, we proposed the assessment item Special Services, 
Treatments, and Interventions in the Inpatient Psychiatric Setting for 
the Special Services, Treatments, and Interventions category of the 
IPF-PAI. This assessment item requires the assessor to indicate which 
psychiatric treatments, or restrictive interventions may have been used 
during the IPF stay.
    Psychiatric Treatments and Restrictive Interventions allow the 
assessor to check off all that apply from the list. Psychiatric 
Treatments include medications, brain stimulation, and non-
pharmacological treatments other than brain stimulation. Restrictive 
Interventions include the use of seclusion, restraints, or other 
restrictive interventions. This assessment item, including 
instructional text and response options, is shown on the IPF-PAI Item 
Set, available under IPF-PAI Resources at https://qualitynet.cms.gov/ipf/PAI. Additionally, detailed instructions for administration would 
be provided through training and the IPF-PAI Guidance Manual, the draft 
of which is available under IPF-PAI Development and Testing resources 
at https://qualitynet.cms.gov/ipf/PAI. For results of IRR and 
feasibility from field (beta) testing, see Table 6. When asked about 
their agreement for including the six treatment or intervention types, 
most TEP members replied Strongly Agree or Agree (100 percent for 
Medications; 89 percent for Brain Stimulation, Non-pharmacological 
Treatment, Seclusion, and Restraints; and 67 percent for Other 
Restrictive Interventions).
    In the FY 2027 IPF PPS proposed rule, we noted that the IRR for 
some assessment items in this category were low. In our investigation 
of the low reliability statistics for the treatment or intervention 
Non-pharmacological Treatment, which included reviewing the testing 
data, comparing discrepancies in coding responses, and reviewing the 
hypothetical case studies and guidance manuals, we determined that the 
structure and definitions in some of the assessment items related to 
this treatment/intervention type were not well understood. We did not 
find this to be unexpected considering the complexity of the assessment 
item (that is, a multi-part, branch item), and that IPF staff were 
unfamiliar with administering this assessment. Non-pharmacological 
treatments, including but not limited to psychotherapy and psychosocial 
interventions, are recommended by clinical practice 
guidelines,26 27 and have been shown to be beneficial to 
patients.28 29 For these reasons, we considered it important 
to retain an assessment item on this topic. As noted, 89 percent of TEP 
members responded Strongly Agree or Agree with the inclusion of Non-
pharmacological Treatment in the IPF-PAI. We stated that we believed 
that low reliability indicates a need for targeted support, by means of 
revising the guidance manual to provide distinct definitions for each 
component of this assessment item, examples of coding to emphasize the 
multi-part nature of the item, provider training, and focused 
Frequently Asked Questions documents to help select the appropriate 
response, which we stated we will develop and provide if this proposal 
is finalized.

iv. IPF-PAI Medical Conditions and Comorbidities Category
    Section 1886(s)(4)(E)(i)(IV) of the Act requires the inclusion of 
patient assessment data with respect to medical

[[Page 48549]]

conditions and comorbidities, such as diabetes, congestive heart 
failure, and pressure ulcers. In the FY 2027 IPF PPS proposed rule, we 
proposed the assessment item Primary Medical Condition for the Medical 
Conditions and Comorbidities category of the proposed IPF-PAI. This 
assessment item assesses the category of the primary diagnosis 
associated with the IPF stay; assessors would select their response 
from the list of common diagnostic categories (for example, anxiety 
disorders, mood disorders, schizophrenia and other psychotic 
disorders). This assessment item, including instructional text and 
response options, is shown on the IPF-PAI Item Set, available under 
IPF-PAI Resources at https://qualitynet.cms.gov/ipf/PAI. Additionally, 
we stated that detailed instructions for administration would be 
provided through training and the IPF-PAI Guidance Manual, the draft of 
which is available under IPF-PAI Development and Testing resources at 
https://qualitynet.cms.gov/ipf/PAI. For results of IRR and feasibility 
from field (beta) testing, see Table 6. Most TEP members (89 percent) 
responded Strongly Agree or Agree to including the Primary Medical 
Condition data element on the IPF-PAI. In future potential versions of 
the IPF-PAI, we could consider the addition of comorbidities.
v. IPF-PAI Impairments Category
    Section 1886(s)(4)(E)(i)(V) of the Act requires the inclusion of 
patient assessment data with respect to impairments, such as 
incontinence and an impaired ability to hear, see, or swallow. In the 
FY 2027 IPF PPS proposed rule, we proposed the Hearing, Speech Clarity, 
and Vision assessment items for the Impairments category of the IPF-
PAI. For these assessment items, the assessor records a patient's 
ability to hear, a description of their speech pattern, and their 
ability to see in adequate light by selecting the level of impairment 
from a set of response options within each assessment item. These 
assessment items, including instructional text and response options, 
are shown on the IPF-PAI Item Set, available under IPF-PAI Resources at 
https://qualitynet.cms.gov/ipf/PAI. Additionally, we stated that 
detailed instructions for administration would be provided through 
training and the IPF-PAI Guidance Manual, the draft of which is 
available under IPF-PAI Development and Testing resources at https://qualitynet.cms.gov/ipf/PAI. We proposed that the Hearing, Speech 
Clarity, and Vision assessment item be evaluated at admission only, in 
recognition that they are unlikely to change during the IPF stay, which 
is typically brief (about 7 days, on average). For results of IRR and 
feasibility from field (beta) testing, see Table 6. When asked about 
their agreement for including these assessment items in the proposed 
IPF-PAI, most TEP members replied Strongly Agree or Agree (89 percent 
for Hearing; 78 percent for Speech Clarity; 67 percent for Vision).

vi. Administrative Data Category
    Section 1886(s)(4)(E)(ii)(VI) of the Act authorizes other 
categories of assessment items as determined appropriate by the 
Secretary. In the FY 2027 IPF PPS proposed rule, in addition to the 
assessment items discussed above, we proposed including an 
Administrative data category to collect certain administrative 
information to enable database management and record matching. We 
stated that collecting data in this category would support accurate 
linkage of assessment records within CMS' Internet Quality Improvement 
and Evaluation System (iQIES), or a successor system, and facilitate 
analyses by CMS, including linking assessment data with other CMS data 
sources (for example, payment and claims data). We noted that these 
data could also enable stratification of outcomes by patient and stay 
characteristics, which would support accurate comparisons between 
facilities and patient populations. These proposed data elements 
included: Legal Name of Patient, Birth Date, Sex, Social Security [SSN] 
and Medicare Numbers, Facility Provider Numbers (National Provider 
Identifier, CMS Certification Number (CCN)), Admission/Discharge Date, 
Payer Information Primary Payer, Type of Record, Assessment Reference 
Date, Reason for Assessment, Type of Admission/Type of Discharge, and 
IPF-PAI Completion Date. These assessment items, including 
instructional text and response options, are shown on the IPF-PAI Item 
Set, available under IPF-PAI Resources at https://qualitynet.cms.gov/ipf/PAI. Additionally, we stated that detailed instructions for 
administration would be provided through training and the IPF-PAI 
Guidance Manual, the draft of which is available under IPF-PAI 
Development and Testing resources at https://qualitynet.cms.gov/ipf/PAI. We proposed that assessment items for the Administrative category 
be collected at both admission and discharge.
    We received public comments on these proposals.
    Comment: A commenter stated that admission assessments should be 
used to foster meaningful patient-provider conversations and patient 
engagement, noting that when patient-reported outcome measures are 
discussed and incorporated into care planning, they can build trust, 
support collaborative goal setting, and improve retention in treatment 
rather than serving as merely administrative data collection.
    Response: We acknowledge the commenter's view that admission 
assessments, including patient-reported

[[Page 48551]]

outcome measures, can foster patient-provider conversations, patient 
engagement, trust, collaborative goal setting, retention in treatment, 
and care planning. We wish to clarify that the IPF-PAI is not intended 
to fully replace the intake assessment or discharge planning process, 
to replace the clinical conversation, or to function merely as 
administrative data collection without other uses. Rather, we designed 
the instrument to minimize burden while meeting the statutory 
requirement for standardized assessment data that will enable 
comparison of assessment data across IPFs and inform our understanding 
of resource use. We agree on the importance of patient-reported 
outcomes to understanding quality--the IPF Quality Reporting Program 
currently uses the Psychiatric Inpatient Experience (PIX) measure of 
patient experience--but note that because the IPF-PAI is completed by 
clinicians rather than patients it is not the appropriate tool for 
collecting patient-reported outcomes as currently designed.
    Comment: Many commenters stated that the IPF-PAI, as proposed, is 
misaligned with the needs and realities of the inpatient psychiatric 
setting, and rather, that it is based on a post-acute care model. A few 
commenters stated that needs, treatments, outcomes, and overall case 
mix are very different between post-acute care providers and IPFs and 
therefore the existing post-acute care PAIs are not a good source for 
IPF-PAI development.
    Response: We agree that the IPF-PAI should reflect the inpatient 
psychiatric setting and not simply import a post-acute care model for a 
patient assessment instrument. Existing post-acute care patient 
assessments were only one of the many sources that we reviewed in 
developing the IPF-PAI; the clinical and setting specific expertise 
provided by the TEP was fundamental in selecting the most appropriate 
assessment items. As discussed in section V.C.2. of this final rule, 
the item-selection process included review of clinical practice 
guidelines, prior public comment, alpha and beta testing, and input 
from behavioral health clinicians, IPF administrators, and individuals 
with IPF patient experience. Although IPFs serve patients with distinct 
clinical needs, we recognize the importance of IPFs documenting a full 
range of patient characteristics in a standardized way, including 
functional status, mobility, and impairments, because these factors are 
relevant to care planning, safety, and discharge planning as well as an 
IPF's resource use.
    Comment: Several commenters expressed concern that misalignment 
between the content of the IPF-PAI and core constructs of the inpatient 
psychiatric setting will produce data that are prone to 
misinterpretation. A few commenters stated that data quality matters 
because once data are captured, they are used for benchmarking, 
comparisons, and policy evaluation.
    Response: The initial assessment items were selected for the IPF 
setting to meet the statutory categories. We seek to ensure consistent 
collection of information by including standardized assessment items 
and response options, with clear guidance available for clinicians 
documenting the assessment. Detailed instructions for administration 
will be provided through training for all applicable IPF staff and the 
IPF-PAI Guidance Manual. We will monitor the data and make refinements 
as needed, through future rulemaking, to ensure IPF-PAI data are 
suitable for its intended use.
    Comment: Many commenters stated that the IPF-PAI is not clinically 
relevant to the IPF setting, does not assess what matters most in 
psychiatric treatment, and is not useful for treatment planning. 
Several commenters gave examples of topics that they consider to be 
most important to inpatient psychiatric treatment that are not 
represented or represented adequately in the IPF-PAI, including illness 
presentation, symptom severity, suicide risk, co-occurring behavioral 
or medical conditions, treatment response, behavioral functioning, 
psychiatric outcomes, and clinical progress. Several commenters stated 
that because of these missing topics and what they stated is 
misalignment with the care setting, the IPF-PAI is not able to inform 
future payment or to produce data useful to CMS or the public for 
understanding the care that IPFs deliver.
    Response: The IPF-PAI was designed to be integrated with existing 
admission and discharge processes and is not intended to be a 
comprehensive treatment planning record. We appreciate commenters' 
input on additional topics that are relevant to the IPF setting. The 
initial IPF-PAI includes a minimal set of assessment items which were 
selected to address each statutorily required category while minimizing 
implementation burden associated with a new instrument. These 
assessment items include clinically relevant topics on suicide 
screening, primary medical conditions, and special services, 
treatments, and interventions. However, it does not include all topics 
that are clinically relevant to the IPF patient population because 
including all such topics would expand the initial instrument and 
increase burden for IPFs.
    Comment: A commenter stated that the IPF-PAI does not assess 
clinical factors that would indicate evidence-based practice, and that 
the items are based on chart abstraction not assessment, and will not 
supply meaningful data to IPFs or CMS. A few commenters expressed 
concern that the IPF-PAI requirements do not adequately reflect the 
unique clinical and operational realities of inpatient psychiatric 
care, which is largely focused on stabilizing individuals in crisis and 
supporting recovery. These commenters stated that because psychiatric 
progress fluctuates across the course of the stay assessment is a 
continuous clinical process which depends on real-time observations. A 
few commenters stated that the items that have relevance to psychiatric 
treatment are process measures and not quality or outcome-related 
items. A commenter stated that it is unclear how the proposed 
assessment items provide useful information to facilities and patients, 
and how these items would lead to improved quality of care. The 
commenter recommended that CMS consider whether the items finalized for 
the IPF-PAI assessment will help facilities improve care and help guide 
individuals and families in choosing facilities based on quality. A few 
commenters stated that, because the assessment is not clinically 
relevant and does not reflect quality or outcomes of psychiatric 
treatment, it would introduce significant workflow, staffing, and 
resource burdens without clear benefit to patients, potentially 
shifting focus from direct clinical care. A few commenters stated that 
if the IPF-PAI does not inform treatment planning, it will be treated 
as compliance work, rather than be integrated into the clinical 
workflow.
    Response: The instrument was developed through TEP review and alpha 
and beta testing, which showed that the items were viewed as clinically 
useful for IPF assessment, care planning, and discharge planning, while 
being feasible to collect in routine workflows. We wish to clarify that 
that IPF-PAI does not contain any quality measures, only assessment 
items that are meant to collect data about patient characteristics and 
treatment processes in a standardized way. The IPF-PAI is intended to 
collect standardized information that can enable comparison across all 
IPFs, as described by the CAA, 2023; it is not intended to replace 
clinical assessment, limit the clinical phases at which assessment 
occurs, or

[[Page 48552]]

serve as a comprehensive treatment planning tool.
    Comment: Several comments stated that the IPF-PAI includes items 
that are unlikely to change or be improved during the IPF stay because 
they are not clinically relevant to the visit and not addressed 
clinically in IPFs. A commenter stated that it is unlikely that the 
IPF-PAI will lower costs as the metrics are not relevant to outcomes 
that can be improved in a short inpatient stay.
    Response: We agree that some IPF-PAI items may be unlikely to 
change during an IPF stay or may not be the primary focus of 
psychiatric treatment. This initial version of the IPF-PAI is not 
focused on items expected to improve during the stay. Section 
1886(s)(4)(E) of the Act requires standardized patient assessment data 
across specified categories, and some items describe patient status, 
patient complexity, or stay characteristics at the relevant assessment 
time point. We did not propose the IPF-PAI as a cost-reduction 
intervention. It is being implemented to collect standardized patient 
assessment data, and section 1886(s)(6) of the Act provides that IPF-
PAI data may be considered in future revisions to the IPF PPS payment 
methodology. After reviewing these comments and comments received 
regarding specific assessment items (described later in this section), 
we are finalizing policies that IPFs that collect and submit Hearing, 
Speech Clarity, Vision, and Mobility: Chair/Bed-to-Chair Transfer with 
respect to admission will be deemed to have collected and submitted 
these items with respect to both admission and discharge because it 
unlikely that the assessment of those items at admission would differ 
from assessment of the same item at discharge during the typical IPF 
stay. Refer to section V.4.b. of this final rule for a complete 
discussion of assessment timing.
    Comment: A commenter stated that if the IPF-PAI identified a change 
or deficit, IPFs may need to establish workflows that include a process 
to provide additional resources for patients where a need is 
identified, which may require additional staffing on units. The 
commenter gave the example of patients with mobility issues that put 
them at greater risk of falls potentially needing 1:1 staffing to 
ensure safety.
    Response: We acknowledge the commenter's concern that identifying a 
need, change, or deficit through the IPF-PAI may affect workflows, 
resources, or staffing. The IPF-PAI collects standardized patient 
assessment data; it does not itself specify a required staffing model 
or intervention. We note that IPFs are responsible for identifying and 
providing clinically appropriate interventions and staffing.
    Comment: A few commenters stated that the IPF-PAI does not function 
as a true patient assessment instrument but is a hybrid documentation 
form containing process checkboxes, administrative items, and only a 
few screening questions, that capture whether a process occurred but 
not that patient's status. A commenter stated that the IPF-PAI is not 
well-matched to the workflows of IPFs, and that rather than being 
informed by real-time clinical evaluations, the IPF-PAI would likely be 
completed by reviewing medical records and copying information on the 
standard form, creating burden without providing actionable information 
to the care team. A commenter expressed concern that many IPF patients 
will not be able to complete these assessment items and that refusals 
will be the response entered for most of the assessment.
    Response: We note that Section 1886(s)(4)(E) of the Act requires a 
standardized patient assessment instrument that collects data across 
specified categories and any other category determined appropriate by 
the Secretary. Administrative items are necessary to support admission 
and discharge record matching and database management; other items 
collect standardized patient assessment data across the statutory 
categories. We understand the commenters' reference to a ``true'' 
patient assessment instrument to mean that the commenters do not 
believe it is a comprehensive clinical assessment. Standardized patient 
assessment data may include patient status, patient characteristics, 
services and interventions during the stay, and administrative 
information needed to link records accurately. The IPF-PAI was designed 
to complement and rely on existing admission and discharge assessment 
processes which remain clinically valuable and appropriate. We note 
that the IPF-PAI is not designed to be completed by patients 
themselves. The IPF-PAI was developed to be completed based on 
assessments conducted during the three days following admission or on 
the day of discharge using information available in patients' records. 
As discussed in the FY 2027 IPF PPS proposed rule (91 FR 17739), 
feedback and evidence gathered from our TEP and through field testing 
indicates that most administrative and clinical data will be available 
in the medical record as part of routine recordkeeping, which may 
reduce duplicative collection.
    The available testing results do not indicate that refusals would 
be entered for most of the assessment. Field (beta) testing found the 
candidate assessment items generally feasible. An assessment item was 
considered feasible if data could be collected from more than 90 
percent of assessed patients (that is, less than 10 percent missing 
data). The IPF-PAI Testing Report also found generally low missingness 
across most items. CMS will provide detailed administration 
instructions through the IPF-PAI Guidance Manual and training.
    Comment: Several commenters stated the IRR of assessment items was 
low, which may affect comparison of data across IPFs. Several 
commenters stated that CMS should revise and retest the IPF-PAI to 
demonstrate higher reliability before mandatory reporting begins. A few 
commenters expressed concern that expanding the guidance manual and 
training would not address reliability concerns.
    Response: In developing the initial version of the IPF-PAI, we 
considered reliability together with validity, feasibility, TEP input, 
the statutorily mandated data categories, and burden. Field (beta) 
testing assessed IRR using percent agreement and Cohen's Kappa and 
showed that reliability varied by item (FR 91 17742), with the lowest 
performance on both measures of reliability (that is, percent agreement 
and Cohen's Kappa) observed for Psychiatric Treatments: Non-
pharmacological treatment other than brain stimulation, Restrictive 
Interventions: Other restrictive interventions, and relatively low but 
fair reliability for Vision. For the 3 of 13 assessment items which had 
the lowest or lower reliability results, we analyzed the reasons for 
lower agreement or consistency among testers and will address these 
issues as appropriate (for example, through additional guidance and 
training) prior to the beginning of data collection for the IPF-PAI. 
Specifically, we noted low IRR in areas that require staff to assess 
whether ``other'' interventions occurred (such as for Non-
pharmacological Treatment within the Special Services, Treatments, and 
Interventions Category). Nonetheless, these assessment items were 
supported by the TEP, determined to be valid and feasible, low in 
burden, and aligned with one or more statutorily mandated data 
categories. We note that we received comments recommending that CMS 
clarify what types of treatments and interventions should be coded with 
these ``other'' response options, which supports our interpretation 
that low IRR was in part

[[Page 48553]]

due to lack of clear guidance during field (beta) testing.
    Regarding the Vision assessment item, after analyzing the results 
of the field (beta) testing, we determined that one vignette depicted a 
clinical presentation which would require additional guidance. Based on 
this analysis, we have made revisions to the Guidance Manual to clarify 
the use of assistive devices for the Vision and Hearing assessment 
items. We wish to clarify that completing the Vision assessment item 
does not require administering a comprehensive vision exam. Rather, any 
IPF staff person who has completed training on the IPF-PAI and reviewed 
the Guidance Manual will be able to complete the assessment item using 
information from typical interaction with the patient, the medical 
record, patient self-report, or reports from caregivers. We trust that, 
with appropriate familiarizing and training, IPF staff will also be 
able to use this assessment item reliably. We also expect that IPFs 
will provide a level of assessment and accommodations appropriate for 
the patient, as required by the Conditions of Participation.
    To improve consistency of data collection among IPFs, we will 
continue to expand our guidance manual to provide more detailed 
information about what types of ``other'' non-pharmacological 
treatments and restrictive interventions should be included, and 
detailed training and guidance on how to complete the Vision 
assessment. In addition, we will continue to use feedback from IPFs in 
refining guidance and note that a clinical help desk will be available 
to answer specific questions on coding. This expanded guidance, 
training, and help desk resources will provide more clarity to IPF 
staff and improve consistent data collection.
    Comment: Many commenters expressed concern that results from the 
field test may not be applicable to some of the proposed assessment 
items because these items were added or modified after testing.
    Response: The version of the assessment used in field (beta) 
testing contained more assessment items than we proposed as the initial 
version of the IPF-PAI. Of the individual items proposed for the IPF-
PAI, only the Suicide Screening assessment item was modified in 
response to TEP and tester feedback after field (beta) testing had 
ended. Specifically, we revised the item to collect standardized 
information on whether suicide screening occurred and the method of 
assessment, rather than require the use of a specific standardized 
suicide risk assessment tool. TEP members gave feedback that IPFs use a 
variety of established screening and assessment approaches and 
expressed preferences for different screening tools. The revised 
approach supports comparability across facilities while preserving the 
flexibility to use the screening or assessment approach that best fits 
the IPF's clinical practice and the patient's needs. Because of the 
importance of the suicide screening topic, and the version of the 
assessment item used during field (beta) testing was otherwise deemed 
to be valid, feasible, supported by the TEP, low burden, and fulfilled 
one of the statutorily mandated data categories, we did not want to 
delay inclusion of this assessment item in the IPF-PAI. We provide more 
information about the changes to the Suicide Screening item later in 
this section.
    Comment: A few commenters expressed concern that the development 
and testing processes were insufficient to implement the IPF-PAI in the 
IPF Quality Reporting Program. A few commenters stated that CMS 
selected items for inclusion in the IPF-PAI without due consideration 
of the testing results. A commenter expressed concern that there was 
insufficient discussion during the TEP meeting. Another commenter 
expressed concern that psychiatrists were underrepresented in the 
development and testing processes.
    Response: We used a multi-stage, multi-stakeholder process to 
identify, evaluate, and test candidate assessment items. This process 
included identifying applicable clinical topic areas within the 
statutorily mandated categories, reviewing clinical practice guidelines 
and standardized assessment items used in behavioral health settings or 
CMS quality reporting programs, considering prior public comments (89 
FR 23200 through 23204), conducting alpha and beta testing, and 
obtaining input from the TEP through several meetings and written 
feedback. The TEP members were selected by the IPF-PAI development 
contractor following a request for interested participants from the 
general public communicated through our existing IPF Quality Reporting 
Program list-serves and communication channels. The 16 TEP members (10 
of whom were IPF clinicians) included a psychiatrist, a psychiatric 
nurse practitioner, psychologists, nurses, and social workers, IPF 
executives and administrators, individuals with experience as patients 
in IPFs, and an interoperability expert.\30\ Through this process we 
selected the IPF-PAI assessment items from an initial set of dozens of 
candidate assessment items based on the item's relevance, feasibility, 
validity, extent to which it meets the statutorily mandated 
requirements, and whether it was supported. We then used results from 
alpha and beta testing, and input from the TEP, to select the final set 
of items to propose. We may consider additional domains or items 
through future rulemaking.
---------------------------------------------------------------------------

IPF-PAI development is available under IPF-PAI Development and 
Testing resources at https://qualitynet.cms.gov/ipf/PAI.
---------------------------------------------------------------------------

    Comment: A few commenters expressed concern that the field test was 
limited to approximately 1 percent of IPFs which may not be a 
representative sample.
    Response: We note that while recruitment for the field test used 
convenience sampling, the IPFs that participated in the field test 
represented a heterogeneous mix with respect to facility type, size, 
ownership, geographic region, patient case mix, and urban and rural 
facilities to improve the validity of the results and applicability to 
a national program.
    Comment: A commenter expressed concern that testing results may be 
improved by using actual assessment of real IPF patients instead of 
relying on hypothetical case data.
    Response: Field (beta) testing used both hypothetical case studies 
and an observational field test with real patients in participating 
IPFs. The hypothetical case studies assessed inter-rater reliability, 
while the observational field test confirmed feasibility and validity 
in a real-world setting. Both testing modes were used to collect data 
on time-to-complete.
    Comment: A few commenters stated that the IPF-PAI uses different 
numeric codes for the same response options, such as Yes and No, across 
assessment items which may increase the risk of coding errors or 
increase training burden.
    Response: The CMS Data Element Library assigns numbers to the 
response options on our standardized patient assessment instruments. 
These numbers serve as identifiers to support data management and long-
term comparability across systems. These numbers are not intended to 
imply rank, order, or severity. Instead, each number simply points to a 
predefined category used for data management and long-term 
comparability across systems. The meaning of each response option is 
conveyed entirely by the text label, and users should rely on those 
labels rather

[[Page 48554]]

than the numeric codes when selecting a response option.
    Comment: A few commenters recommended that CMS provide clear coding 
guidance to increase the feasibility and consistency of implementation, 
with some commenters specifically recommending guidance with respect to 
``Other'' response categories. A commenter recommended ensuring the 
Guidance Manual is concise so that it can be used effectively for 
implementation and training.
    Response: We note that the revised IPF-PAI Guidance Manual, posted 
with the publication of this final rule, incorporates additional 
guidance based on comments received in response to our proposals. The 
IPF-PAI Guidance Manual describes the intent for each assessment item, 
the steps for assessment, coding instructions, coding tips, and 
examples. For assessment items with ``Other'' response options, the 
appropriate use of this response, coding tips, and examples are 
included in the guidance manual. To support systematic collection of 
IPF-PAI data and improve clarity, we will continue to work with IPF 
staff, clinicians, and other interested parties, to provide training 
and improve guidance materials in advance of implementation. We will 
monitor questions received by the help desk and the IPF-PAI data that 
is submitted to CMS to identify areas for additional guidance or 
training.
    Comment: A commenter stated that many inpatient psychiatric 
patients are unable to appropriately answer assessment questions, and 
that the proposed IPF-PAI does not have exclusions for patients who are 
unwilling or unable to answer questions.
    Response: Although we did not propose a patient-level exclusion to 
the IPF-PAI as a whole due to patient refusal or inability to respond, 
IPFs are able to indicate nonresponse as a valid response option for 
certain applicable assessment items (for example, Suicide Screening).
    Comment: A commenter recommended that CMS provide guidance 
regarding which staff are appropriate to complete the IPF-PAI.
    Response: We recognize that treatment team composition and staff 
roles vary across IPFs, and therefore, we provide IPFs the flexibility 
to implement the IPF-PAI into their existing assessment workflows as 
appropriate. IPFs are responsible for ensuring that staff members 
participating in the assessment process, and completing the section(s) 
of the IPF-PAI, have the requisite knowledge and are qualified to 
complete an accurate assessment per facility, state, and federal policy 
and requirements. For purposes of estimating information collection 
burden, we assumed that the IPF-PAI would most often be completed by a 
variety of clinical or other IPF staff, including Medical Records 
Specialists, Registered Nurses, Licensed Practical or Licensed 
Vocational Nurses, and Mental Health and Substance Abuse Social 
Workers.
    Comment: Many commenters stated that significant mobility 
limitations are typically identified during existing screening and 
intake processes to ensure the facility can safely meet a patient's 
medical needs. Many commenters stated that some IPFs do not provide 
physical therapy or occupation therapy and may not admit patients who 
require these services. A few commenters stated that IPFs typically 
admit only ambulatory patients, based on not having the capacity to 
care for patients with significant physical health needs, such as those 
that impact mobility or those that are not able to transfer from chair 
to bed independently.
    Response: We appreciate this feedback. We maintain that patient 
functional status provides important information to CMS on resource 
intensity.
    Comment: Many commenters stated the Mobility: Chair/Bed-to-Chair 
Transfer item reflects other care settings (such as post-acute 
settings) rather than the acute psychiatric setting. Many commenters 
stated that most IPF admissions are not related to mobility 
rehabilitation. A few commenters stated that while function is 
important in inpatient psychiatric treatment, it is not the focus of 
psychiatric treatment and therefore that Chair/Bed-to-Chair Transfer is 
not a meaningful dimension of behavioral health. A commenter 
recommended that we exclude mobility from bonus payment calculations if 
the IPF-PAI is used for payment and consider it only for cost 
adjustment if evidence shows reduced mobility increases IPF clinical 
needs or costs.
    Response: We acknowledge that mobility is generally not related to 
the patient's primary reason for being admitted to an IPF and that a 
patient at an IPF likely will not receive services during their IPF 
stay related to improving mobility if they have mobility limitations, 
whereas mobility may be more closely tied to a patient's reason for 
admission and treatment plan in post-acute care settings. We note that 
we did not propose Mobility: Chair/Bed-to-Chair Transfer in the IPF-PAI 
because we believe that IPFs are providing or should be providing 
specialized services related to mobility treatment and rehabilitation. 
Rather, we proposed this assessment item because a majority of TEP 
members supported its inclusion on the IPF-PAI, noting that this 
information is routinely collected as it informs service delivery 
during the inpatient stay and discharge planning. In addition, this 
assessment item meets the statutorily required category of Functional 
Status, specifically the mobility example set forth in the CAA, 2023. A 
patient's ability to transfer to and from a bed to a chair or 
wheelchair, including the level of assistance required when the patient 
does not complete activities independently, reflects added resource 
intensity and this information could therefore be used to adjust 
payments to IPFs. For example, patients that require assistance to 
transfer from a bed to a chair may also require assistance to transfer 
to a dining chair to participate in meals. We acknowledge the 
commenter's recommendation to only consider this assessment item for 
payment adjustment if we find that mobility is related to IPF resource 
use. We note that the IPF Quality Reporting Program is a pay-for-
reporting program; an IPF's performance on any of the assessment items 
in the IPF-PAI will not impact payments. Rather, the only impact on 
payments would be if an IPF does not comply with reporting requirements 
or meet the compliance threshold (see section V.C.4.b. of this final 
rule).
    Comment: Several commenters stated that mobility or other items 
related to functional status, impairments, medical conditions, or 
comorbidities are unlikely to change meaningfully during shorter IPF 
stays. These commenters stated that assessing this topic at admission 
and discharge was duplicative and would not produce meaningful 
information. Several commenters stated that, because IPFs generally 
cannot improve mobility during a typical stay, the assessment item may 
not produce meaningful quality information. A few commenters 
recommended assessing mobility only at admission.
    Response: We note that although we proposed requiring this item on 
both admission and discharge assessments, we did not propose that this 
item would be used to assess change in functional status between 
admission and discharge. However, in response to comments and in 
recognition that meaningful change in mobility is not expected for an 
IPF stay, we are finalizing to require the Mobility: Chair/Bed-to-Chair 
Transfer assessment item at the admission only. Under this finalized 
policy, IPFs that collect and submit the Mobility: Chair/Bed-to-Chair

[[Page 48555]]

Transfer item with respect to admission will be deemed to have 
collected and submitted it with respect to both admission and 
discharge. In our convenience sample of IPF patients in the field 
(beta) test, around 10 percent of patients were assessed as having 
functional limitations (mobility) at admission. Although the sample is 
small and not nationally representative, the findings indicate that 
some patients in IPFs require assistance that may impact resource use. 
We maintain that assessing this information in a standardized way will 
enable comparison across IPFs and will provide useful information to 
CMS for understanding the resource needs of IPFs.
    Comment: A few commenters recommended assessing mobility through 
patient self-report rather than through structured observation.
    Response: We acknowledge the importance of patient self-report when 
assessing mobility and note that the Guidance Manual states that the 
steps for assessing the Mobility: Chair/bed-to-chair transfer 
assessment item includes the option of incorporating patient-self 
report combined with direct observation. Specifically, the Guidance 
Manual states that assessors should ``assess the patient's mobility 
performance based on direct observation, incorporating patient self-
report and reports from qualified clinicians, care staff, or family 
documented in the patient's medical record during the assessment 
period.''
    Comment: A few commenters recommended different functional status 
items for the statutorily mandated Functional Status data category, 
including self-care, medication management, activities for daily living 
(ADLs), need for walking assistance, need for modifications and 
accommodations, and fall risk.
    Response: We thank commenters for these recommendations. During the 
development of the IPF-PAI, including in alpha and beta testing, and in 
meetings with the TEP, we considered a broader range of functional 
status topics, including self-care, mobility (other than bed-to-chair 
transfer), medication management, use of assistive devices, and other 
ADL-related items. To select appropriate assessment items for the IPF-
PAI we took into account testing results, reported clinical usefulness, 
and perceived challenges or workflow issues identified by the TEP and 
in field (beta) testing. This approach helps minimize burden while 
capturing core functional status information, as required by statute. 
We may consider whether additional or different functional status 
assessment items should be included in future versions of the IPF-PAI 
through future rulemaking.
    Comment: A few commenters supported including the suicide screening 
assessment item at admission and discharge.
    Response: We thank the commenters for their support for the 
inclusion of Suicide Screening on the IPF-PAI at admission and 
discharge.
    Comment: A few commenters stated that reporting on suicide 
screening may not produce valuable information because suicide 
screening is a routine activity that is already required under 
accreditation requirements. Many commenters stated the suicide 
screening item records whether screening occurred and by what 
assessment method, rather than information such as assessed risk level, 
ideation, whether the individual was actively suicidal or homicidal, 
violent tendencies, safety plan, protective factors, clinical response, 
treatment planning needs, or change over time. These commenters stated 
that these limitations decrease the usefulness of the item for patient 
care, quality measurement, outcomes, and cross-facility comparison. A 
few commenters also recommended that the item show whether risk was 
identified and addressed.
    Response: As discussed in section V.C.3.b.ii. of this final rule, 
we identified screening for suicidal thoughts and behaviors as an 
important clinical topic with relevance to quality of care and resource 
use. We note that all TEP members responded Strongly Agree or Agree to 
including a Suicide Screening assessment item on the IPF-PAI. We chose 
not to require use of a specific standardized suicide risk assessment 
tool which could provide more detailed information--for example, on the 
patient's risk level and treatment plans--in the initial version of the 
IPF-PAI because TEP members noted that IPFs use a variety of 
established screening and assessment approaches, and expressed 
preferences for different screening tools. Instead, we designed the 
item to collect standardized information on whether suicide screening 
occurred and the method of assessment, which supports comparability 
across facilities while preserving the flexibility to use the screening 
or assessment approach that best fits their clinical practice and the 
patient's needs. We recognize that the additional types of information 
commenters suggested we include are important for clinicians in IPFs, 
and CMS may consider collecting this information through future 
rulemaking; however, we maintain that collecting whether and how 
patients were screened for suicide risk will provide CMS with 
standardized information across IPFs on an important topic.
    Comment: A few commenters stated that suicide risk changes during 
an IPF stay and should be assessed at clinically appropriate points, 
including admission or intake, during the stay, and discharge. A 
commenter stated the Suicide Screening item is a process measure and 
raised concerns about the assessment window and stated discharge-
related suicide screening should occur within 24 hours of discharge, 
not any time after the first three days.
    Response: We proposed that the Suicide Screening assessment item be 
collected at admission and discharge, however IPFs may assess for 
suicide risk throughout the stay, as clinically appropriate. As with 
other aspects of the IPF-PAI, in this initial version we strived to 
collect the most important information while minimizing burden to 
facilities. This includes burden that may be introduced if the IPF-PAI 
is unnecessarily restrictive, for example, by requiring a specific 
screening tool or clinical care process, such as screening for suicide 
risk within 24 hours of discharge, when a less restrictive data 
collection was likely to yield the information we need at this time. We 
wish to clarify that we did not propose Suicide Screening as a quality 
measure. Its inclusion on the IPF-PAI is intended to collect 
standardized data across IPFs that could inform payment and aspects of 
the IPF Quality Reporting Program. This assessment item collects 
information that is not currently available to CMS. For this initial 
version of the IPF-PAI, we sought to meet the statutorily mandated 
categories while minimizing data collection burden, and we may consider 
this recommendation as we evaluate potential future refinements to the 
IPF-PAI through future rulemaking.
    Comment: A few commenters stated that converting the suicide 
assessment into a process item may render prior testing conclusions 
inapplicable to the new assessment item. A few commenters recommended 
additional testing or monitoring to ensure that the assessment item is 
relevant and valid.
    Response: We interpret these comments as referring to changes that 
were made to the Suicide Screening item between alpha and beta testing, 
and subsequent to beta testing. We maintain that the changes between 
beta testing and the initial version of the IPF-PAI do not undermine 
evidence of face validity and feasibility drawn from the testing and 
TEP input. We note that

[[Page 48556]]

all members of the TEP (100 percent) responded Strongly Agree or Agree 
to inclusion of a Suicide Screening item on the IPF-PAI indicating that 
the assessment item is relevant. Descriptive statistics in the field 
(beta) test supported face validity for a question that asks whether 
the patient has been screened for suicide risk.\31\
---------------------------------------------------------------------------

    \31\ See Exhibit 23 in Appendix B of the IPF-PAI Testing Report. 
Available at: https://qualitynet.cms.gov/files/69cd2666346406199a2239f2?filename=IPF-PAI_Testing_Report.pdf.
---------------------------------------------------------------------------

    To clarify, we included Columbia Suicide Severity Rating Scale (C-
SSRS) in alpha testing, and in beta testing, as an optional assessment 
item, if the assessor first indicated that the patient was screened 
using this tool. For the Suicide Screening assessment item on the 
initial version of the IPF-PAI, we do not include the C-SSRS. During 
developing of the IPF-PAI, we received feedback from alpha test 
participants as well as the TEP that while the C-SSRS was in widespread 
use, there are other suicide risk screening tools used in IPFs. The TEP 
encouraged CMS to allow flexibility to IPFs, and to not require the use 
of a standardized screening that they would not otherwise use. Although 
the C-SSRS was included in the field (beta) test, requiring it to be 
collected for all patients could have been burdensome and duplicative 
of other standardized suicide screening tools. In addition, the 
inclusion of the C-SSRS as an optional screening--to be used if the IPF 
did not indicate they screened with another tool--would have produced 
incomplete data for IPF patients, limiting its usefulness. Because of 
broad support for this topic being on the IPF-PAI, and based on the 
information about workflow and processes, we proposed an item that 
would collect the information that is important to CMS at this time, 
meets the statutory requirement, and is applicable across IPFs.
    Comment: A few commenters recommended separating ``patient 
declined'' from ``unable to respond.''
    Response: In response to these comments, we are updating the 
response options for this assessment item. The final version of the 
IPF-PAI will include separate response options for ``patient declined'' 
and ``unable to respond'' for the Suicide Screening assessment item.
    Comment: Several commenters recognized the importance of suicide 
screening but stated that it does not measure cognitive function or 
broader mental status. The commenters recommended addition of 
assessment items on functional cognition, fluctuations in cognitive 
function, and other dimensions of mental status.
    Response: We do not consider suicide-related thoughts and behaviors 
to be indicative of cognitive impairment. Rather, we understand mental 
status to encompass a wide range of cognition, orientation, mood, and 
decision-making capacities, including thought content. Of the candidate 
assessment items considered for the IPF-PAI in this category, results 
of our development and testing activities consistently identified 
Suicide Screening as the most important, broadly applicable, and 
feasible topic to use to meet this statutorily mandated category. We 
acknowledge commenters' recommendations to add functional cognition or 
other aspects of mental status, and we may consider these 
recommendations as we evaluate potential future refinements to the IPF-
PAI through future rulemaking.
    Comment: A few commenters include broader mental status and 
symptom-improvement measures in the domain of Cognitive Function and 
Mental Status, such as Patient Health Questionnaire-9 (PHQ-9), 
Generalized Anxiety Disorder 7-item scale (GAD-7), or Positive and 
Negative Syndrome Scale (PANSS).
    Response: We also acknowledge commenters' recommendation to include 
broader mental status and symptom-improvement measures, such as PHQ-9, 
GAD-7, or PANSS. In the development of the IPF-PAI, we did consider 
screening tools for depression and anxiety, such as the PHQ-9 and the 
GAD-7, even including the PHQ-9 in the alpha test. However, we received 
feedback in the alpha test that the PHQ-9 was not in widespread use in 
IPFs, and participants believed it was a tool designed for use in 
primary care or outpatient behavior health settings, rather than for 
individuals facing acute psychiatric symptoms who are being treated in 
an IPF. In addition, IPF staff described a preference to use the 
assessment tools appropriate for their patient population, for example, 
a depression assessment tailored for geriatric patients. With regard to 
symptom improvement, while we acknowledge the importance of the IPF 
stay in moderating severe symptoms, we also understand that improvement 
for many symptoms often happens over weeks or months.
    The initial version of the IPF-PAI is intended to meet the 
statutorily mandated requirement to collect standardized patient 
assessment data across the required categories while being mindful of 
reporting burden on IPFs. For that reason, we proposed a minimal set of 
assessment items for the initial IPF-PAI. Adding additional symptom-
improvement would expand the initial IPF-PAI beyond the assessment 
items proposed for this rulemaking. We may reconsider these 
recommendations in the future.
    Comment: A commenter was supportive of the Primary Medical 
Condition Category assessment item.
    Response: We thank the commenter for supporting the Primary Medical 
Condition Category assessment item. Most TEP members responded Strongly 
Agree or Agree to including this item on the IPF-PAI. Field (beta) 
testing also supported the feasibility and reliability of this item, 
with no feasibility challenges identified and good IRR.
    Comment: Several commenters expressed concern that the Medical 
Condition category assessment item may increase burden because the 
response options are not aligned with ICD-10 diagnostic codes which are 
used on claims. A commenter stated that this assessment item duplicates 
information that CMS already gets through claims.
    Response: We note that these categories are aligned with the 
categories on which IPFs report annually as part of the IPF Quality 
Reporting Program, not with ICD-10 diagnostic codes, with the exception 
of the Eating Disorders response option, which was added at the 
recommendation of the TEP. To support assessors in correctly 
classifying primary diagnosis category, we will provide crosswalk 
tables of ICD-10-CM codes with the primary diagnosis categories on the 
IPF Quality Reporting Program page on QualityNet.
    This item is intended to collect a structured primary diagnosis 
category that supports comparability across IPFs. We note that 
diagnosis information submitted through claims is limited to Medicare 
patients only, and data collection for the IPF-PAI is applicable to all 
IPF patients aged 18 years and older.
    Comment: A few commenters expressed concerns about inconsistent 
coding, stating that it is difficult to code primary diagnosis 
appropriately because the reasons for admission are not present or are 
represented in multiple diagnostic categories. A commenter recommended 
that CMS revise this assessment item to allow free text completion.
    Response: In our development and testing activities, we found that 
the Primary Medical Condition Category had no feasibility challenges 
and good IRR. Detailed instructions for administration, including 
guidance for situations in which a patient's reason for admission could 
relate to more than

[[Page 48557]]

one diagnostic category, will be provided through training and the IPF-
PAI Guidance Manual. We are requiring structured data instead of free 
text to comply with the CAA, 2023 by enabling comparison of data across 
IPFs.
    Comment: A commenter recommended that CMS collect this information 
once per stay, stating that primary diagnosis is unlikely to change 
meaningfully between admission and discharge, making repeated 
collection unnecessary and burdensome.
    Response: Input from IPF clinicians during development and testing 
affirmed that many patients are admitted with a provisional diagnosis 
that may be updated during the IPF stay. Therefore, we will retain the 
requirement to assess Primary Medical Condition Category at admission 
and discharge.
    Comment: Several commenters stated that some conditions listed in 
the response options for the Primary Medical Condition Category 
assessment item, including delirium, dementia, amnestic disorders, and 
substance use disorder are not eligible primary diagnoses for IPF 
stays.
    Response: The response options to the Primary Medical Condition 
Category assessment item are based on the categories on which IPFs 
report annually to CMS at the facility level, as part of the IPF 
Quality Reporting Program (79 FR 45973). For reference, a 2024 report 
showed approximately 15.5 percent of Medicare beneficiaries treated in 
an IPF had a primary diagnosis of Alzheimer's Disease and Related 
Dementias and approximately 6.3 percent had a primary diagnosis of 
alcohol or drug abuse or dependence.\32\ We note that the IPF-PAI is 
intended to collect comparable data for all IPF patients regardless of 
payer, and that not all payers have the same eligibility policies.

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

    Comment: A few commenters stated that the data generated from the 
Primary Medical Condition Category assessment item would not be 
meaningful or useful to the public, because they are too broad to 
understand facility expertise in treating specific conditions and do 
not provide data on patient outcomes.
    Response: We are not publicly reporting data from the IPF-PAI at 
this time. We proposed this assessment item to fulfill the statutorily 
mandated category of Medical Conditions and Co-Morbidities to collect 
information that can, for example inform resource intensity, or be used 
to stratify patient data, not as a metric of the quality or 
effectiveness of treatment.
    Comment: A few commenters recommended that CMS include secondary 
diagnoses and comorbidities as indicators of medical complexity, 
stating that comorbidities are common in this patient population and 
can require additional resources. A few commenters stated that the IPF-
PAI does not assess illness presentation, acuity, co-occurring 
behavioral health or medical conditions, or trauma history and adverse 
childhood experiences, that would impact costs of care and could be 
used to adjust payments. A commenter recommended that CMS include an 
assessment item, ``Consultation from a non-psychiatric medical 
specialist was required'' to better address the resources required in 
caring for patients with significant medical comorbidities.
    Response: We thank commenters for their suggestions regarding 
additional assessment items related to Medical Conditions or Co-
Morbidities that they believe could help inform resource use across 
IPFs. For this initial version, we sought to meet the statutory 
categories while minimizing data collection burden. We may consider 
additional assessment items to collect information on medical 
complexity, including information about secondary diagnoses or 
comorbidities in future rulemaking.
    Comment: A commenter supported the IPF-PAI assessment items for 
impairments related to hearing, speech clarity, and vision at 
admission.
    Response: We thank the commenter for this support.
    Comment: Many commenters stated that hearing, speech clarity, and 
vision assessments do not support psychiatric treatment planning 
because these items are rarely aligned with the reason for psychiatric 
treatment. These commenters stated that these assessments appeared to 
be drawn from non-psychiatric settings. Many commenters stated that IPF 
staff are not experienced in administering hearing, speech clarity, and 
vision assessments and therefore including these items would require 
staff training. A few commenters also stated that reporting hearing, 
speech clarity, and vision would not provide useful clinical, quality, 
or outcomes information.
    Response: As described earlier in this section of this final rule, 
we undertook a multi-step process to identify appropriate assessment 
items for each statutorily mandated category. One step of that process 
was to review standardized assessment items used in other settings for 
clinical relevance and the ability to reflect resource use. As part of 
that review, we determined that the hearing, speech clarity, and vision 
assessment items are clinically relevant to IPF patients, in that 
comprehensive assessment is a basic component of good inpatient care, 
and information such as whether a patient can hear, see, and speak 
clearly is important for communication, safety, and care planning. In 
testing and TEP review, these assessment items were described as 
clinically useful and already part of routine IPF assessment practices, 
supporting their inclusion in the IPF-PAI. We will provide training and 
guidance on how IPF staff can assess a patient's hearing, vision, and 
speech clarity. We wish to clarify that completing these assessment 
items requires only usual interaction with the patient or review of the 
medical record, and does not require a comprehensive hearing or vision 
exam, or evaluation of speaking ability. Data collected on these 
assessment items could reflect resource intensity. We note that these 
are standardized assessment items, not quality measures, and their 
inclusion on the IPF-PAI is not to provide information on quality or 
outcomes. The IPF-PAI is intended to collect standardized patient 
assessment data across IPFs using the same assessment items, response 
options, standards, and definitions.
    Comment: Many commenters stated that hearing, speech clarity, and 
vision assessments may be difficult or inappropriate for patients 
experiencing acute psychiatric symptoms. A few commenters stated that 
medication side effects or psychiatric symptoms such as hallucinations 
may affect these assessments. A few commenters recommended an option 
for patient refusal or clinician inability to assess. A few commenters 
stated that hearing, vision, and speech clarity are typically 
identified prior to admission to ensure that the facility can meet the 
patient's needs.
    Response: We note that these are not patient interview items, but 
rather assessments of level of impairment completed by IPF staff based 
on information in the medical record and interactions with the patient. 
The IPF-PAI Guidance Manual includes information including ``Coding 
Tips'' to help IPF staff complete these assessment items for patients 
who may be unable to respond to standard assessments including due to 
acute psychiatric

[[Page 48558]]

symptoms.\33\ The causes of any impairments, such as an impairment 
resulting from the side effects of a psychiatric medication side 
effects, are not relevant to the completion of the assessment items. 
Furthermore, assessors have until day 3 of the IPF stay to assess the 
patient's hearing, speech clarity, and vision, which provides time for 
IPF staff to interact with and observe patients in ways that can inform 
their completion of the assessment items. We intend the policy we are 
finalizing in Section V.C.4.B. of this final rule, which lowers the 
compliance threshold from that which we proposed, to provide 
flexibility for IPFs when they encounter challenges with completing the 
IPF-PAI during initial implementation.

Hearing, Speech, and Vision Guidance, see Chapter 3: Section B).
---------------------------------------------------------------------------

    Comment: A few commenters recommended changes to the impairment 
items, including assessing speech clarity at both admission and 
discharge, collecting static impairment-related items only once during 
the IPF stay, modifying hearing, speech clarity, and vision to yes/no 
questions, combining mobility and sensory impairments into one item, 
and adding assessment items for urinary incontinence, bowel 
incontinence, and dysphagia.
    Response: We proposed Hearing, Speech Clarity, and Vision for 
admission-only collection based on testing and clinician input and to 
reflect the fact that these items are unlikely to change during the IPF 
stay. As a result, IPFs that collect and submit Hearing, Speech 
Clarity, and Vision with respect to admission will be deemed to have 
collected and submitted these items with respect to both admission and 
discharge. For the purpose of reflecting resource intensity, the multi-
level response options will provide more granular information than a 
binary yes/no option. We may consider refinements or additional 
impairment items through future rulemaking.
    Comment: A few commenters supported the data elements for the 
Special Services, Treatments, and Interventions Category, specifically 
the Other Restrictive Interventions item (which includes unit 
restrictions, one-to-one observation, and line-of-sight supervision) 
and the non-pharmacological therapies. Commenters stated that these 
assessment items will provide information that is important for the IPF 
setting.
    Response: We thank commenters for their support for these 
assessment items within the Special Services, Treatments, and 
Interventions Category and agree that these items are important for the 
IPF setting. We note that we have revised the name of the Other 
Restrictive Interventions response option to be Other Interventions as 
it is a response option to the Restrictive Interventions section of the 
Special Services, Treatments, and Interventions in the Inpatient 
Psychiatric Setting assessment item.
    Comment: Several commenters stated that guidance was limited or 
unclear for components of the Special Services, Treatments, and 
Interventions in the Inpatient Psychiatric Setting item. Commenters 
specifically recommended clarifying the Medications item, the Non-
Pharmacological Treatment item, Unit Restrictions, One-to-One 
Observations, and ``Other'' response options. Several commenters stated 
that nearly all patients receive interventions in the psychiatric 
treatments item and recommended additional response options (for 
example, categories of medication type) to improve the value of the 
data.
    Response: We appreciate these recommendations. The revised IPF-PAI 
Guidance Manual, posted with the publication of this final rule, will 
incorporate additional guidance based on comments received in response 
to our proposals. In addition, to support collection of accurate 
standardized IPF-PAI data, we will offer training in advance of 
implementation, as well as a help desk for ongoing support, and 
continue to improve guidance materials as challenges are identified. We 
will monitor data submitted for the initial IPF-PAI to determine if 
additional assessment items or response options would increase the 
value of these data.
    Comment: Several commenters stated that CMS underestimated the 
burden of reporting data on Special Services, Treatments, and 
Interventions. Several commenters stated that information on special 
services and restrictive interventions is not readily available in 
structured EHR fields so data collection would require burdensome 
mapping between the EHR and the IPF-PAI.
    Response: We understand commenters' concerns about our estimate of 
collection of information burden for the Special Services, Treatments, 
and Interventions Category. As discussed in the FY 2027 IPF PPS 
proposed rule (91 FR 17749), our estimates for completing each 
assessment item part of 0.30 minutes per assessment item part is 
similar to estimates used in other CMS PAI data collections, and was 
supported by field (beta) testing, in which we calculated that median 
time to complete was 0.15 minutes per assessment item part (see section 
VI.C.2. of this final rule for more information). We also acknowledge 
that reporting data directly from the EHR may require updates to 
existing documentation processes and workflows. To provide IPFs more 
time to make these and other updates and in response to concerns raised 
by commenters, we are providing three quarters of voluntary reporting 
prior to mandatory reporting of the IPF-PAI in Q3 of 2028. To further 
reduce burden and because these data are specific to the IPF stay, we 
are making a modification to require data for the Special Services, 
Treatments, and Interventions Category to be collected at Discharge 
only, with a lookback period of the entire IPF stay. This extended 
lookback period will ensure that the data is submitted with respect to 
the entirety of the IPF stay, including admission and discharge.
    Comment: A commenter expressed concern that documenting Special 
Services, Treatments, and Interventions at discharge for patients with 
longer stays would be burdensome because patients may have received 
many different special services, treatments, and interventions 
throughout their stay, and identifying those would require review of 
the patient's entire medical record.
    Response: The data reported in response to the Special Services, 
Treatments, and Interventions Category collects important elements of 
IPF treatment for all patients for whom the IPF-PAI is completed. We 
note that the discharge assessment captures whether the patient 
received each listed service, treatment, or intervention at least once 
during the inpatient stay. Facilities are not expected to determine the 
number of occurrences or dates on which services were provided. We 
encourage IPFs that routinely treat patients with longer stays to 
identify strategies, such as incorporating ongoing tracking of these 
services through developing logs for these items, rather than relying 
on retrospective review of patient medical records at discharge.
    Comment: Several commenters recommended that CMS not include the 
Seclusion and Restraint sections of this assessment item because of 
duplication with the Hours of Physical Restraint Use (HBIPS-2) and 
Hours of Seclusion Use (HBIPS-3) quality measures in the IPF Quality 
Reporting Program or the Conditions of Participation reporting 
requirements. A commenter stated that CMS had previously proposed 
removing

[[Page 48559]]

the HBIPS-2 and HBIPS-3 measures because of high and unvarying 
performance and that collecting data on similar data elements will not 
provide meaningful information to compare IPFs. A few commenters 
recommended modified or additional response options (such as 
distinguishing between manual and mechanical restraint) to collect more 
meaningful data.
    Response: We recognize that IPFs currently collect and report 
similar information related to seclusion and restraint use to CMS. 
Because IPFs routinely collect and maintain records of the use of 
seclusion and restraint in compliance with the Conditions of 
Participation, we believe reporting whether a patient received these 
interventions during the applicable assessment period represents a 
limited additional burden. We also believe there is value in collecting 
patient-level information on the use of seclusion and restraint during 
an individual's inpatient psychiatric stay, in addition to the 
facility-level rates of restraint and seclusion hours per 1,000 patient 
hours captured by the HBIPS-2 and HBIPS-3 quality measures. We also 
note that the IPF-PAI will collect more granular data than existing 
requirements, including type of restraint (chemical or physical), and 
use of other interventions such as unit restrictions, line of sight 
supervision, and 1:1 observation. We appreciate commenters' suggestions 
to add additional response options to add more granularity, such as 
manual versus mechanical restraint, and will consider these 
recommendations as we evaluate potential future refinements to the IPF-
PAI through future rulemaking. Regarding the comment that we previously 
proposed removing HBIPS-2 and HBIPS-3 because these measures had high 
and unvarying performance, we note that we did not finalize that 
proposal because we agreed with many commenters who stated that these 
measures continued to provide meaningful information despite their 
performance (83 FR 38603), and we believe that collecting complimentary 
information through the IPF-PAI will also provide meaningful 
information.
    Comment: A few commenters expressed concern about including 
information regarding ECT utilization because of the sensitive nature 
of ECT data and potential uses of publicly available data sets. A 
commenter stated that CMS already receives data regarding ECT use as 
part of IPF claims.
    Response: We note that under the Special Services, Treatments, and 
Interventions Category we require IPFs to report data on Brain 
Stimulation treatments received by the patient. While we do receive 
some information regarding ECT on claims for Medicare patients, data on 
the use of brain stimulation, including ECT, Transcranial Magnetic 
Stimulation, and other types of brain stimulation, would provide 
valuable information about resource use in the IPF setting. We note 
that we do not currently have any policies under which we would 
publicly report data collected under the IPF-PAI.
    Comment: A few commenters recommended additional assessment items 
for the Special Services, Treatments, and Interventions Category, 
specifically ``high-cost technology, treatments, and interventions'' 
and ``Involuntary Commitment/Treatment Over Objection.'' A commenter 
recommended including detailed information about the timing and use of 
recreational therapy in the IPF setting.
    Response: We thank the commenters for these recommendations. We may 
consider refinements or additional items related to Special Services, 
Treatments, and Interventions through future rulemaking. We note that 
we included an item for voluntary/involuntary admission in the 
administrative data required for submission of the IPF-PAI.
    Comment: A commenter supported aligning administrative data 
elements between the IPF-PAI and existing patient assessment 
instruments.
    Response: We thank the commenter for their support.
    Comment: A commenter requested clarification regarding whether 
patient name, birth date, and sex are required if other identifiers 
like Medicare number and SSN are submitted.
    Response: As discussed in the FY 2027 IPF PPS proposed rule (91 FR 
17742), assessment items in the Administrative category, will support 
accurate linkage of assessment records within iQIES. Because some 
individuals share names and birth dates, iQIES' matching algorithm uses 
multiple pieces of information for each patient to ensure that the 
correct records are matched; internal analysis has found that having 
multiple pieces of information about a patient increases the likelihood 
of correct matching. Patient name, birth date, and sex are therefore 
essential for record matching. As discussed later in this section, we 
are not finalizing the inclusion of SSN for this initial version of the 
IPF-PAI, and we will require Medicare Number only for patients for whom 
Medicare is the primary payer.
    Comment: Several commenters stated that SSN may be unavailable 
because some facilities do not routinely collect this information or 
because SSN is unknown. Several commenters stated that collecting 
detailed identification information, including SSN, would likely not be 
approved by patient advocacy committees and may impact patient trust, 
engagement, and willingness to disclose sensitive information 
throughout the course of their stay. Several commenters expressed 
concerns that collection of SSN poses a privacy risk. A commenter 
stated that CMS has neither demonstrated the necessity of requiring 
SSNs for all patients, regardless of payer, nor that there are not less 
burdensome options available to operate the IPF Quality Reporting 
Program and recommended that CMS designate SSN as optional.
    Response: We appreciate these comments. We proposed collecting SSN 
because it improves our ability to uniquely identify patient records 
and to match assessment data for the same patient longitudinally. After 
consideration of public comments regarding the collection of SSN, we 
are removing SSN from the initial version of the IPF-PAI.
    Comment: A commenter expressed concerns that the items in the 
Administrative Data category are covered under HIPAA and raise concerns 
about breach-risk and associated penalties. A few commenters 
recommended providing additional information about the necessity of 
data collection, the intended uses of these data, and the planned data 
protections because of the sensitive nature of psychiatric inpatient 
admission and the importance of maintaining patient privacy.
    Response: We appreciate these comments. We are collecting certain 
identifiable data in the Administrative Data category to support 
patient identification, record matching, and database management 
functions associated with standardized assessment data. We are 
collecting these data on all patients aged 18 and older because the 
IPF-PAI is to be collected for all such patients in an IPF. In the FY 
2027 IPF PPS proposed rule (91 FR 17745), we stated that submission of 
IPF-PAI data to CMS through the web app, PARIT, would follow standard 
HIPAA-compliant encryption protocols. For IPFs who work with vendors to 
develop custom HL7[supreg] FHIR[supreg] submission pathways--for 
example, to extract data directly from the EHR-we expect IPFs to 
operate in compliance with applicable privacy and security requirements 
for transmitting health care data. After IPF-PAI data are received by 
CMS, they will be stored in iQIES, a CMS system that operates under 
federal security requirements and

[[Page 48560]]

is compliant with the Federal Information Security Management Act of 
2014 (FISMA).\34\ In practice, this level of security means that users 
must verify their identity, use multi-factor authentication, and have 
approved access roles, and that the system is subject to ongoing 
security and privacy reviews and monitoring.

    Comment: A few commenters asked CMS to provide guidance on how 
facilities should respond to assessment items where a patient refuses 
to provide information on their Sex, and if CMS will consider an 
assessment incomplete if a patient declines to provide this 
information.
    Response: We thank the commenter for these questions. Sex remains a 
required administrative data element, as proposed, to support record 
matching and database management. If a patient declines to self-report 
sex during their intake process, we defer to the IPF's policy on 
medical recordkeeping for how to complete this information.
    Comment: A commenter recommended that CMS replace the term ``sex'' 
with ``sex at birth.''
    Response: We thank the commenter for the feedback. It is the policy 
of HHS to use the term ``sex'' when referring to person's biological 
classification as male or female.\35\ We intend for IPFs to populate 
this field with the corresponding information, even if it is labeled 
differently in the IPF's medical recording keeping system.

    Comment: A commenter stated that Payer information may be 
burdensome to collect, as this information is often stored separately 
from the patient's record of treatment.
    Response: We appreciate this feedback. We maintain that payer 
information will be useful to CMS for stratifying patients in analyses 
and understanding differences in case mix and resource use across payer 
type. Although it may require some additional effort to collect, it 
provides important standardized information for CMS and can usually be 
obtained from administrative records.
    Comment: Several commenters expressed concern about the proposed 
use of multiple administrative assessment items for patient matching, 
stating that routine variations or errors in data entry in these fields 
could result in mismatched assessment data and financial consequences 
for IPFs. A commenter stated that CMS has acknowledged that minor 
discrepancies can trigger financial penalties.
    Response: We thank the commenters for their feedback. We wish to 
clarify that the matching process described in section V.C.3.b.vi. of 
this final rule supports CMS in associating admission assessments with 
discharge assessments in our databases. We wish to clarify that data 
matching is not required to meet the compliance threshold, and 
therefore, variations or errors in data entry in the administrative 
fields will not have financial consequences for IPFs.
    Comment: A commenter expressed concerns about manual entry 
requirements for NPI, CCN, and assessment reference dates and 
recommended that these be automated.
    Response: We appreciate this feedback and recognize that automating 
some administrative assessment items would reduce burden and data entry 
errors. IPFs that use the FHIR[supreg] APIs for data submission have 
flexibility in how the tool is integrated into their EHR. That is, some 
IPFs may purchase or develop solutions that reduce burden by auto-
populating administrative data or other information. For the initial 
version of PARIT, the free web app, we are not able to offer this 
functionality. We will consider this functionality for future versions 
of the web app.
    Comment: A few commenters stated that additional patient-level 
information would provide useful information about resource needs. 
These commenters specifically recommended language and cultural 
factors, social determinants of health, and information about social 
isolation. A few commenters also recommended including items regarding 
the need for patients and providers to attend legal hearings and the 
need for staff to collaborate with outside entities.
    Response: For this initial version of the IPF-PAI, we sought to 
meet the statutorily mandated categories while minimizing data 
collection burden. We may consider refinements or additional items 
related to Special Services, Treatments, and Interventions through 
future rulemaking.
    Final Decision: After consideration of the comments received, we 
are finalizing these assessment items for the IPF-PAI, to fulfill the 
categories named in the CAA, 2023, and to establish a new category of 
Administrative Data, with modifications. We will require the assessment 
item Mobility: Chair/Bed-to-Chair Transfer to be collected at admission 
only. IPFs that collect and submit Mobility: Chair/Bed-to-Chair 
Transfer with respect to admission will be deemed to have collected and 
submitted it with respect to both admission and discharge. We will 
require that the assessment item Special Services, Treatments, and 
Interventions in the Inpatient Psychiatric Setting be collected at 
Discharge only, with an extended lookback period of the entire IPF 
stay, from admission through discharge. In the Administrative Data 
category, we are not finalizing inclusion of SSN for the IPF-PAI, and 
the Medicare Number will only be required for patients for whom 
Medicare is the primary payer (see section V.C.4.b. of this final 
rule).
4. Form, Manner, and Timing of Data Collection and Submission of the 
IPF-PAI
a. Reporting Periods and Data Submission Deadlines for the IPF-PAI
    In the FY 2027 IPF PPS proposed rule, we proposed mandatory 
reporting of the IPF-PAI beginning with a reporting period of October 
1, 2027, through December 31, 2027, impacting the FY 2029 payment 
determination. That is, IPFs would be required to collect and submit 
IPF-PAI admission and discharge assessments for all patients aged 18 
years and older, regardless of payer, beginning October 1, 2027; 
admission and discharge assessments conducted October 1, 2027, through 
December 31, 2027, would impact the FY 2029 payment determination.
    We proposed that beginning with the FY 2030 payment determination 
and for subsequent years, IPF would be required to report data with 
respect to admissions and discharges for all patients age 18 years and 
older that occur during the calendar year from January 1 through 
December 31, that is, the calendar year two years preceding the FY 
payment determination year (for example, January 1, 2028 through 
December 31, 2028 for the FY 2030 payment determination, January 1, 
2029 through December 31, 2029 for the FY 2031 payment determination, 
and so on). We proposed that for each calendar year reporting period, 
the IPF-PAI data must be submitted as quarterly reporting periods by a 
submission deadline of the 15th day of the second month after the end 
of the calendar quarter, as outlined in Table 7. See Table 7 for 
proposed submission deadlines through the FY 2031 payment 
determination. We stated that we would also publish upcoming submission 
deadlines on the CMS QualityNet website at https://qualitynet.cms.gov/.
    Specifically for the purpose of determining which applicable 
reporting quarter the admission or discharge falls within, we proposed 
to use the Assessment Reference Date (ARD) associated with each 
admission and

[[Page 48561]]

discharge. The Admission ARD would be not later than 3 days after the 
admission and the Discharge ARD would be the day of discharge. We 
proposed to require that an IPF submits an admission assessment by the 
15th day of the second month after the end of the calendar quarter in 
which the ARD for the admission assessment occurred. We likewise 
proposed that an IPF submits a discharge assessment by the 15th day of 
the second month following the calendar quarter in which the ARD for 
the discharge occurred. The submission deadlines and associated payment 
determination years that we proposed for the first nine quarters of 
IPF-PAI data collection are shown in Table 7. We noted that when the 
submission deadline falls on a Friday, Saturday, Sunday, or Federal 
holiday, we would move the data submission deadline to the next 
business day.
[GRAPHIC] [TIFF OMITTED] TR31JY26.029

    We noted that notwithstanding the quarterly submission deadlines 
for IPF-PAI data described in this section, based on best practices 
learned from our long-standing experience with standardized patient 
assessment instruments for post-acute care providers, we recommended 
rolling submissions of IPF-PAI records to CMS throughout the data 
collection period as patients are admitted and discharged for more 
timely, accurate, and efficiently collected assessment data. The data 
submission methods we proposed are described in section V.C.4.c. of 
this final rule. We noted that ongoing submission of IPF-PAI records 
allows an IPF to monitor their compliance rates through on-demand 
provider reports available through internet Quality Improvement and 
Evaluation System (iQIES). We stated that we would issue technical sub-
regulatory guidance for the IPF-PAI assessment items and data 
collection, including recommended frequency of submissions via the IPF-
PAI Guidance Manual (draft available under IPF-PAI Resources at https://qualitynet.cms.gov/ipf/PAI).
    We received public comment on these proposals.
    Comment: A commenter expressed support for the consistency of IPF-
PAI reporting periods and data submission deadlines with existing 
Inpatient Rehabilitation Facility -Patient Assessment Instrument (IRF-
PAI) processes.
    Response: We thank the commenter for their support. We agree that 
alignment across standardized patient assessment instruments can be 
helpful.
    Comment: Many commenters recommended that CMS delay implementation 
until additional instrument development and interested parties 
engagement take place. Several commenters recommended less burdensome 
reporting structures, including completing the PAI only at admission, 
using one PAI rather than separate admission and discharge PAIs, 
avoiding an initial one-quarter partial-year reporting period, delaying 
reporting until January 1, 2028, or avoiding payment impacts during 
initial implementation.
    Response: We are finalizing our proposal to require separate IPF-
PAI submissions for admission and discharge, but based on commenters' 
feedback, we are modifying the requirements to no longer require some 
items to be collected at both time points. As described in section 
V.C.3. of this final rule, we will require the Mobility assessment item 
at Admission only--rather than at Admission and Discharge, as proposed. 
IPFs that collect and submit the Mobility assessment item with respect 
to admission will be deemed to have collected and submitted it with 
respect to both admission and discharge. We will require the Special 
Services, Treatments, and Interventions in the Inpatient Psychiatric 
Setting assessment item at Discharge only--rather than at both 
Admission and Discharge--with an extended lookback period to ensure 
that the data is collected with respect to the entirety of the IPF 
stay, from admission through discharge. These modifications reduce the 
reporting burden at each time point.
    Additionally, based on commenters' feedback we are modifying the 
proposed beginning date for mandatory reporting. As described in 
section V.C.4.b. of this final rule, we are finalizing a policy in 
which IPFs may begin voluntary reporting of the IPF-PAI beginning 
October 1, 2027. Mandatory reporting of the IPF-PAI then begins on July 
1, 2028 for Q3 CY 2028. Successful submission of IPF-PAI data for Q3 
2028 and Q4 2028 will impact the FY 2030 payment determination under 
the IPF Quality Reporting Program. We interpret commenters' concern 
regarding partial year reporting periods to be based on the potential 
for small data sets reported through an unfamiliar reporting structure 
to impact IPF payments. Because we are providing three quarters of 
voluntary data submission during which IPFs can become familiar with 
IPF-PAI data collection and reporting, and increasing the partial year 
reporting

[[Page 48562]]

period from one quarter to two quarters this concern is mitigated by 
our modified policies.
    Comment: Several commenters recommended aligning with IPF Quality 
Reporting Program data submission requirements by requiring annual 
reporting rather than aligning with quarterly patient assessment 
reporting in other settings.
    Response: We understand commenters' concerns that quarterly 
submission deadlines for the IPF-PAI will increase the number of 
reporting deadlines that IPFs are required to meet. However, as 
described in the FY 2027 IPF PPS proposed rule (91 FR 17744), based on 
best practices learned from our experience with standardized patient 
assessment instruments for post-acute care providers, we recommended 
rolling submissions of IPF-PAI records to CMS throughout the data 
collection period as patients are admitted and discharged for more 
timely, accurate, and efficiently collected assessment data. We note 
that we define timeframes for data collection for both Admission and 
Discharge: the Admission ARD of 3 days and the Discharge ARD of the day 
of discharge. We expect an IPF to complete the IPF-PAI during those 
timeframes, rather than attempting to complete the IPF-PAI 
retrospectively at the time of the data submission requirement. In 
addition, to support accuracy, ongoing submission of IPF-PAI records 
allows IPFs to monitor their compliance rate through the provider 
reports available through iQIES.
    Comment: A few commenters raised burden concerns, including 
significant workflow changes and labor resource needs, difficulty 
recruiting and maintaining staff for the work, the risk that smaller 
facilities may struggle with quarterly submission deadlines, and 
clinical concerns with assessing patients during the first two days of 
psychiatric admission when they may be in acute crisis, medically 
unstable, or unable to meaningfully participate in assessment.
    Response: As described in section V.C.4.b. of this final rule, 
based on commenters' feedback we are finalizing a policy in which IPFs 
will have three voluntary quarters of data submission beginning October 
1, 2027, to become familiar with the IPF-PAI and adapt their workflows 
as needed, before mandatory submission. We are also finalizing a lower 
compliance threshold than the proposed 80 percent, beginning at 50 
percent for when the quarterly reporting periods become mandatory, then 
increasing to 70 percent beginning with the CY 2030 reporting period, 
which starts January 1, 2030 (see section V.C.4.b.). Additionally, our 
finalized policy reduces the number of assessment items collected at 
each time point, as described in this section. These several 
modifications to reduce reporting burden, provide a longer 
implementation timeline for IPFs, and provide additional flexibilities 
including the voluntary reporting period help address the anticipated 
challenges described by commenters including for smaller facilities in 
order to facilitate successful implementation. We understand the 
commenters' concern that patients may be in acute crisis or medically 
unstable during the first days of their stay. We note that the ARD for 
the admission assessment is 3 days from the date of admission, not two 
as indicated by the commenter. We acknowledge there may be situations 
in which IPFs may report data as ``not applicable'' if they are unable 
to assess patients due to acute crisis or medical instability. We refer 
readers to the IPF PAI Manual for additional information on use of the 
``not applicable'' code.\36\ As discussed in response to other comments 
in this section and described in the FY 2027 IPF PPS proposed rule (91 
FR 17744), we maintain that there are benefits to the quarterly 
submission deadlines for IPF-PAI data that will support IPFs in 
submitting accurate data on an ongoing basis, and allowing them to 
monitor their compliance rates throughout the year, providing early 
feedback on compliance issues, should they occur.

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

    Comment: A commenter stated that Special Services, Treatments, and 
Interventions reporting would be more feasible using the first three 
days of admission, a seven-day lookback before discharge, or 
prospective tracking of physician-ordered special treatments, rather 
than requiring long lookbacks across hybrid records and multiple 
reporting systems.
    Response: We acknowledge the commenter's concerns about challenges 
related to completing the Special Services, Treatments, and 
Interventions in the Inpatient Psychiatric Setting assessment item. We 
note that, as described in section V.C.3. of this final rule, based on 
commenters' feedback, we are finalizing a modified policy to require 
the Special Services, Treatments, and Interventions (SSTI) assessment 
item at Discharge only--rather than at both Admission and Discharge. 
Because the first three days will no longer be captured under the 
Admission assessment for this assessment item, we are also changing the 
lookback period for it to the entire stay. That is, the modified 
assessment item will be collected only at the Discharge time point, but 
assessors will populate this item with treatments and interventions 
administered during the first three days of the stay (the Admission 
period), as well as during the remainder of the stay. We intend for 
this change to reduce some reporting burden for this item, while still 
providing information on SSTI in the Inpatient Psychiatric Setting from 
across the entire stay, from admission to discharge. This information 
is valuable for CMS to understand resource intensity and the types of 
treatments and interventions used in IPFs.
    Final Decision: After consideration of the public comments 
received, we are finalizing the reporting periods and data submission 
policies and deadlines with modifications. Because of concerns 
expressed by commenters regarding the burden and complexity associated 
with requiring both admission and discharge assessments for patients 
with stays of less than 3 calendar days we are finalizing a policy 
under which IPFs will not be required to complete a separate discharge 
assessment for patients whose length of stay is less than 3 calendar 
days. Instead, for these patients, IPFs will be required to collect 
limited items from the discharge assessment item set as part of the 
admission assessment.\37\ This modification reduces burden and 
simplifies processes while still collecting the important patient 
assessment information. In addition, we are finalizing that, for the 
purpose of determining which applicable reporting quarter the admission 
or discharge falls within, the IPF should use the admission or the 
discharge date, rather than the Admission ARD and the Discharge ARD, as 
we had proposed.
---------------------------------------------------------------------------

    \37\ The assessment items from the Discharge assessment required 
for patients with stays of less than 3 days will be specified in the 
Guidance Manual and represented as skip patterns in the FHIR[supreg] 
Implementation Guides. For the implementation of the IPF-PAI on 
October 1, 2027, those items are Discharge Date, Discharge Type, and 
Special Services, Treatments, and Interventions in the Inpatient 
Psychiatric Setting.
---------------------------------------------------------------------------

    Table 8. shows data submission deadlines through the FY 2031 
payment determination using the finalized reporting period and data 
submission deadline policies, updated to reflect the voluntary 
reporting period and starting reporting quarter for mandatory 
reporting, as described in section V.C.4.b. of this final rule.

b. Compliance Threshold for the IPF-PAI To Receive the Applicable 
Annual Payment Update Beginning With the FY 2029 Payment Determination
    In the FY 2027 IPF PPS proposed rule, we proposed that an IPF would 
need to complete 100 percent of the IPF-PAI assessment items on 80 
percent of the IPF-PAIs submitted to satisfy the IPF Quality Reporting 
Program data reporting requirements for the applicable annual payment 
determination. We proposed that an IPF that fails to submit 100 percent 
of the assessment items on at least 80 percent of the IPF-PAIs 
submitted to CMS would be deemed non-compliant with the IPF Quality 
Reporting Program reporting requirements and, as a result, would be 
subject to a 2-percentage point reduction to its annual payment update 
as required by section 1886(s)(4)(A) of the Act.
    We proposed this 80 percent compliance threshold as a starting 
point (rather than proposing a 100 percent threshold), understanding 
that it will take time for IPFs to become familiar with the data 
collection and submission workflows of this new program requirement. We 
stated that we will monitor data completion rates and provide training 
and other implementation resources to help IPFs be successful in 
meeting or exceeding the 80 percent compliance threshold. We stated 
that over time, in future rulemaking, we plan to incrementally increase 
the compliance rate that an IPF would need to achieve in order to be 
considered compliant with the IPF Quality Reporting Program IPF-PAI 
requirement. We noted that we adopted a similar approach of 
incrementally increasing the compliance threshold over time with the 
standardized patient assessment instruments used by post-acute care 
providers.
    We proposed that for the FY 2029 payment determination, the 
compliance rate for each IPF would be calculated for the Q4 2027 
reporting quarter, and that for the FY 2030 payment determination and 
subsequent years, the compliance rate for each IPF would be calculated 
based on the entire CY 2028 reporting period (that is, four CY 
reporting quarters of IPF-PAI data).
    We proposed to codify the data completion requirement of 100 
percent of required assessment items for at least 80 percent of 
submitted assessments for the IPF-PAI at the proposed new Sec.  
412.433(h).
    We received public comments on this proposal.
    Comment: A commenter expressed support for the alignment of IPF-PAI 
compliance thresholds with IRF-PAI compliance thresholds.
    Response: We thank the commenter for their support.
    Comment: Several commenters expressed concern that the 80 percent 
compliance threshold for complete assessments is too high for initial 
implementation. These commenters described implementation challenges 
and stated that it will take time for the IPF-PAI to be integrated into 
workflows in a way that IPFs will be able to achieve such a high 
completion rate. A few commenters expressed concern regarding the 
effects of a 2-percentage point payment reduction and recommended 
reducing the compliance threshold, postponing payment reductions, or 
both. A commenter recommended a three-year phased implementation 
transitioning from 60 percent in year 1 to 80 percent by year 3. A 
commenter suggested that CMS could consider adjustments to the 
threshold based on facility size, stating that smaller facilities are 
often under resourced and understaffed, especially rural facilities.
    Response: We appreciate the commenters' concerns. Based on 
commenters' feedback we are finalizing a compliance policy with a lower 
compliance threshold than proposed Specifically for the initial 
mandatory reporting period of Q3 and Q4 CY 2028, impacting the 2030 
payment determination, the compliance threshold will be 100 percent of 
the required data elements on 50 percent of the IPF-PAIs submitted. The 
compliance threshold will increase to 100 percent of the required data 
elements on 70 percent of the IPF-PAIs submitted beginning with the CY 
2029 reporting period. We intend that this modification will give IPFs, 
including under-resourced facilities, additional flexibility during 
implementation of the IPF-PAI. We refer readers to Table 9 at the end 
of this section for more information on these updated requirements. We 
note that in section V.C.3.b of this final rule we are also 
establishing policies under which some data elements will not be 
required or will only be required at admission or discharge, not both. 
Table 10, which is included at the end of this section, summarizes 
which data elements are required to meet the 100 percent completion 
requirement.
    Comment: A commenter stated that IPFs may falsely report items to 
meet the compliance threshold, given what the commenter stated was the 
IPF-PAI's lack of clinical relevance, inappropriateness for patients 
with acute mental health needs, burden on staff, and financial risk for 
non-completion.

[[Page 48564]]

    Response: We expect IPFs to submit accurate and complete data in 
accordance with the reporting requirements. We refer readers to section 
V.C.2 of this final rule in which we describe the multi-stage process 
we undertook to identify assessment items that would be responsive to 
the statutory mandate and clinically appropriate for patients in the 
IPF setting. To reduce burden on staff we are also finalizing policies 
to provide more flexibilities to IPFs as they become familiar with the 
IPF-PAI and adjust their workflows as needed. These flexibilities 
include three quarters of voluntary submission before mandatory 
submission, a lower compliance threshold than proposed, and a reduction 
in the number of assessment items collected at each time point (see 
section V.C.3.b. of this final rule).
    Comment: Several commenters stated that the admission and discharge 
assessment windows may overlap, especially for patients who are 
discharged on Day 2 or Day 3, creating duplicative documentation or 
uncertainty about whether both assessments would be required. They 
asked CMS to provide guidance on how to complete the IPF-PAI when the 
assessment windows overlap and recommended that CMS allow for a 
combined or single IPF-PAI to meet the requirement for assessment at 
admission and discharge.
    Response: We understand commenters' concerns regarding the overlap 
in assessment windows. In response to this concern we are establishing 
a modified policy under which IPFs will not be required to complete a 
separate discharge assessment for patients whose length of stay is less 
than 3 calendar days. Instead, for these patients, IPFs will be 
required to collect limited items from the discharge assessment item 
set as part of the admission assessment thus eliminating duplicative 
documentation. In addition, for the purposes of calculating the 
compliance threshold, when an IPF completes an IPF-PAI on a patient 
whose length of stay is less than 3 calendar days, that IPF-PAI will be 
counted as both an admission and a discharge assessment in the IPF-PAI 
compliance calculation. At this time, we do not plan to change any 
requirements for patients with longer lengths of stay, but we intend to 
monitor data submissions and help desk questions associated with such 
patients.
    Comment: Several commenters stated that the IPF-PAI Guidance Manual 
was unclear on how blank assessment items due to missing data or 
patient refusals are included in the compliance calculation.
    Response: As described in section V.C.3.b of this final rule, we 
are finalizing a policy where Medicare Number will be required only for 
patients for whom Medicare is the primary payer. In addition, IPFs are 
able to indicate nonresponse or inability to assess as a valid response 
option for certain applicable assessment items (for example, Suicide 
Screening, Mobility: Chair/Bed-to-Chair Transfer). We will provide 
additional guidance and training on data completeness with respect to 
the compliance threshold as the IPF-PAI is implemented. We note that 
the updated Guidance Manual, which is available on the QualityNet 
website (https://qualitynet.cms.gov/ipf/PAI#tab2) includes guidance on 
indicating when items are unable to be assessed.
    Comment: A commenter expressed concern about an 80 percent match 
and described a data match requirement in other payment programs. This 
commenter discussed the possibility of mismatched data due to spelling 
or keystroke errors.
    Response: For clarification, the proposed 80 percent completion 
requirement was referring to the percent of IPF-PAIs submitted to CMS 
that must be complete for the IPF to meet the IPF Quality Reporting 
Program IPF-PAI requirement and not to any matching. In the proposed 
rule we described the need to collect certain administrative 
information to enable database management and record matching, but 
these database management and record matching capabilities are not 
related to the compliance thresholds.
    Final Decision: After consideration of the public comments 
received, we are finalizing, with modification, the compliance 
threshold for the IPF-PAI. We are making four modifications from the 
policy which was proposed:
     We are finalizing three quarters of voluntary reporting 
beginning October 1, 2027, with mandatory reporting of the IPF-PAI 
beginning July 1, 2028.
     We are finalizing a policy in which the compliance 
threshold--that is, the required percent of IPF-PAIs submitted by an 
IPF that are 100 percent complete in order to meet the IPF Quality 
Reporting Program IPF-PAI requirement for the applicable annual payment 
determination--will begin at 50 percent for the Q3 and Q4 CY 2028 and 
CY 2029 reporting periods, and increase to 70 percent for CY 2030 and 
subsequent reporting periods. In other words, to comply with IPF 
Quality Reporting Program requirements for the IPF-PAI, at least 50 
percent of IPF-PAIs submitted by an IPF must be contain responses for 
all required items for Q3 and Q4 CY 2028 and CY 2029 reporting periods, 
and at least 70 percent of IPF-PAIs submitted by an IPF must be fully 
complete for CY 2030 and subsequent reporting periods. For the FY 2030 
payment determination, the compliance rate for each IPF would be 
calculated using the 2028 Q3 and Q4 reporting period, and for the FY 
2031 payment determination and subsequent years, the compliance rate 
for each IPF would be calculated based on the entire CY reporting 
period (that is, four CY reporting quarters of IPF-PAI data). An IPF 
that does not submit 100 percent of the assessment items on at least 
the required percent of the IPF-PAIs submitted to CMS, as determined by 
the reporting period, would not meet the IPF Quality Reporting Program 
IPF-PAI requirement. As a result, the IPF would be subject to a 2 
percentage-point reduction to its annual payment update, as required by 
section 1886(s)(4)(A) of the Act. We are codifying these data 
completion thresholds for the IPF-PAI at Sec.  412.433(h).
     We are finalizing that Medicare Number will be required 
only for patients for whom Medicare is the primary payer.
     We are also finalizing that an IPF-PAI submitted for 
patients whose length of stay is less than 3 calendar days, will be 
counted as both an admission and a discharge assessment determining 
whether the IPF meets the compliance threshold. Specifically, although 
there will not be a separate discharge IPF-PAI for these patients, the 
admission assessment with some select discharge items will be counted 
as two assessments for purposes of determining whether the IPF meets 
the compliance threshold. That is, if all required items are completed, 
it will be counted as two complete assessments, while if some required 
items are not complete, it will count as two incomplete assessments for 
purposes of determining whether the IPF meets the compliance threshold.

c. Methods of Data Submission for the IPF-PAI
i. Background
    In the FY 2026 IPF PPS proposed rule (90 FR 18520 through 18523), 
we requested comments on the potential use of the HL7[supreg] 
FHIR[supreg] standard for IPF-PAI data submission because we believe 
that the collection and submission of data through health information 
technology (IT), including digital capture and transfer of program data 
through FHIR[supreg], could reduce administrative burden on IPFs 
submitting the IPF-PAI in the long-term. In response to this request 
for comment, commenters expressed support for CMS' intent to transition 
to the FHIR[supreg]-based standard in the IPF Quality Reporting 
Program, particularly for the IPF-PAI, noting the opportunity for a 
FHIR[supreg]-based standard to improve care coordination, enable 
actionable insights, and integrate structured data into electronic 
health records (EHRs) (90 FR 37665 through 37666). A few commenters 
responding to the request for comment highlighted the potential for 
FHIR[supreg] to modernize behavioral health data reporting, enhance 
discharge planning, and enable meaningful performance measurement. In 
the FY 2027 IPF PPS proposed rule (91 FR 17744), we acknowledged that, 
as IPFs have not yet used FHIR[supreg] for program data submission, 
technological, monetary, and staffing barriers may present challenges 
to adoption and use in some facilities. Therefore, we proposed that for 
the submission of IPF-PAI data, we would offer facilities two tools to 
integrate into their existing systems and workflows:
     Web application (web app)
     FHIR[supreg] application programming interfaces (APIs)
    We describe these submission methods in detail in the following 
sections.
    In the proposed rule, we noted that both methods of data submission 
would require user or system authentication using CMS' Health Care 
Quality Information Systems (HCQIS) Access Roles and Profile (HARP), or 
a successor or equivalent CMS-designated identity management system, 
consistent with CMS security and access control requirements. We stated 
that this is the same identity management system that IPFs and their 
vendors currently use to submit other IPF Quality Reporting Program 
data to the CMS Hospital Quality Reporting system, and that both 
proposed methods of IPF-PAI data submission would transmit IPF-PAI data 
securely to CMS, using data security standards required for any CMS 
system, where it would be received and reside in the iQIES environment. 
iQIES is CMS' long-standing system for patient assessment data; post-
acute care providers have been reporting assessment data electronically 
to iQIES since 2019. We clarified that data transfer to CMS via either 
method--the FHIR[supreg] API or web app--would follow standard HIPAA-
compliant encryption protocols. Since the proposed rule, we named the 
web app the Patient Assessment Reporting Interoperability Tool, or 
PARIT.
    We stated that, if finalized, the IPF Quality Reporting Program 
would be the first CMS statutory quality reporting program to use the 
FHIR[supreg] standard to support patient assessment data submission, as 
both data submission methods--the free web app (that is, PARIT) and the 
FHIR[supreg] API--are reliant on underlying FHIR[supreg] resources.\38\ 
Additionally, we stated that introducing the FHIR[supreg] standard to 
the IPF Quality Reporting Program's IPF-PAI requirement involves 
establishing related policies and requirements, such as submission 
methods, data standards and formats, and other program-specific 
requirements.
---------------------------------------------------------------------------

    \38\ Either method of IPF-PAI data submission includes an 
opportunity to use the Substitutable Medical Applications and 
Reusable Technologies (SMART) on FHIR[supreg] framework to either 
configure an EHR-launched workflow that securely authenticates and 
launches the web app, or to implement a custom SMART on FHIR[supreg] 
application, developed by an IPF or a third-party vendor, that 
integrates with the publicly available CMS FHIR[supreg] APIs.
---------------------------------------------------------------------------

ii. Web App Method of Data Submission for IPF-PAI Data
    In the FY 2027 IPF PPS proposed rule, we proposed a CMS-developed 
web app, PARIT, as a method for collecting and submitting IPF-PAI data 
to the iQIES system via the internet. We proposed that we would provide 
and maintain this web app for IPFs to use, free of charge, to enter and 
submit the IPF-PAI admission and discharge assessments for individual 
patients. We proposed that an IPF would be able to review, correct, and 
change these data until the close of each submission deadline using the 
web app. An IPF could use a third party vendor to submit IPF-PAI data 
via the web app on the IPF's behalf. We stated that the open-source web 
app would be accessible in one of two ways: (1) directly through a web 
browser, or (2) configured for launch from an EHR using Substitutable 
Medical Applications and Reusable Technologies (SMART) on FHIR[supreg]. 
In accordance with the Source code Harmonization And Reuse in 
Information Technology Act (SHARE IT Act; Pub. L. 118-187), we stated 
that we would ensure that the source code, documentation, configuration 
scripts, as appropriate, revision history, and other files are located 
in a software storage location (that, a public repository) to which 
access is open to the public.
    We stated that we plan to make this web app available in spring or 
summer 2027, prior to the start of the proposed reporting period that 
would begin October 1, 2027, to allow time for IPFs to gain familiarity 
with the web app and for CMS to provide training.
    We received public comments on this proposal.
    Comment: A commenter recognized the flexibility of offering 
multiple forms of submission but expressed concern that the web 
application would not be available for testing until spring or summer 
of 2027. Another commenter recommended that the web app be released at 
least six months before implementation to allow IPFs time to become 
familiar with the tool. A commenter stated that it is important that 
CMS is planning to provide training on the application and recommended 
that CMS also consider usability testing and technical assistance, such 
as short video tutorials, for users after training.
    Response: We appreciate the commenters' concerns about needing time 
for IPFs to train their staff and become familiar with the PARIT web 
app. We plan to provide training on the IPF-PAI, which will support 
staff in becoming familiar with the assessment items and coding 
guidance. Training on the PARIT web app--as one of the available tools 
for data submission--will begin at least six months before the web app 
becomes available for IPF-PAI data submission, with the web app itself 
going ``live'' for IPF-PAI data submission no later than October 1, 
2027 when the first voluntary reporting quarter begins. As described in 
section V.C.4.b. of this final rule, we are finalizing a policy in 
which IPFs may begin voluntary reporting of the IPF-PAI beginning 
October 1, 2027. Mandatory reporting of the IPF-PAI then begins on July 
1, 2028 for Q3 CY 2028, at which time the PARIT web app will have been 
available for use by IPFs and their vendors for approximately nine 
months. Assessments submitted for Q3 2028 and Q4 2028 will impact the 
FY 2030 payment determination. We expect that the voluntary period will 
provide an opportunity to address any significant challenges 
encountered during the data submission process.
    Final Decision: After consideration of the comments received, we 
are finalizing the web app--PARIT, or a successor tool--as a method of 
data

[[Page 48567]]

submission for the IPF-PAI data as proposed.
iii. HL7[supreg] FHIR[supreg] API Method of Data Submission for IPF-PAI 
Data
    In the FY 2027 IPF PPS proposed rule, we proposed the use of two 
APIs built from the HL7[supreg] FHIR[supreg] specification, based on 
FHIR[supreg] v4.0.1, as another method for submitting IPF-PAI data to 
iQIES via the internet. An API is a documented set of rules and 
specifications that lets one computer program or system request and 
receive information or data from another; specifically, it defines how 
one software component or system can request and use the functions or 
data of another software component or system through a defined 
interface, without requiring knowledge of its internal implementation. 
For healthcare data exchange using an API, the FHIR[supreg] standard 
defines how such data are structured and exchanged. It organizes the 
data into discrete clinical and administrative units called resources, 
such as Patient, Observation, Condition, Medication, and Encounter. 
This method would be suitable for IPFs that use health IT that can be 
modified to support these APIs or that engage with third party vendors 
to implement a custom tool or a custom SMART on FHIR[supreg] 
application using the APIs we have developed to collect and submit IPF-
PAI data to CMS. Under the proposed submission method, we described how 
an IPF could integrate IPF-PAI data collection and submission within 
their EHR workflow using one API to retrieve the applicable IPF-PAI 
assessment items from the EHR, and another API to submit IPF-PAI data 
to CMS. We stated that an IPF could also use a third party vendor to 
submit IPF-PAI data via the FHIR[supreg] API on the IPF's behalf.
    For the proposed implementation of the IPF-PAI, we stated that the 
Data Element Library (DEL) FHIR[supreg] API and associated DEL 
FHIR[supreg] Implementation Guide would support the retrieval of the 
assessment items, and the iQIES FHIR[supreg] API and associated iQIES 
FHIR[supreg] Receiving System Implementation Guide would support the 
assessment data submission to CMS. We made draft versions of the DEL 
FHIR[supreg] Implementation Guide and the iQIES FHIR[supreg] Receiving 
System Implementation Guide available at https://qualitynet.cms.gov/ipf/PAI. We noted that these implementation guides will be updated as 
needed on an annual basis for technical updates and published at the 
same location. We proposed that annual updates will be limited to 
technical, non-substantive updates. Substantive changes to the IPF-PAI 
will be implemented through notice and comment rulemaking. IPFs and 
their vendors will need to use the most recently published 
implementation guides for the applicable IPF-PAI reporting period, 
which we will publish at least six months before the beginning of the 
applicable reporting period. We stated that additional technical 
resources for IPFs and health IT vendors will be made available at 
https://qualitynet.cms.gov/ipf/PAI to support FHIR[supreg] API 
implementation. We noted that we will also engage with software 
developers and vendors through various interested party engagement 
efforts, during which we will respond to questions, comments, and 
suggestions about technical requirements.
    We recognized that IPFs and the health IT vendors supporting IPFs 
will require time to develop and implement data collection and 
submission tools for the IPF-PAI. Therefore, we proposed that, if an 
IPF does not submit IPF-PAI data via the FHIR[supreg] API method 
described in section V.C.4.d.ii. of this final rule, the IPF would be 
required to use the web app for IPF-PAI data submission. Likewise, we 
proposed that if an IPF does not submit IPF-PAI data using the web app, 
the IPF would not meet the IPF-PAI data submission requirement unless 
the IPF submits the data via the FHIR[supreg] API method described in 
section V.C.4.d.iii. of this final rule.
    We received public comments on this proposal.
    Comment: Several commenters supported or recognized the value of 
offering both a web application and FHIR[supreg]-based submission 
pathway, stating that multiple pathways could reduce long-term burden, 
support interoperability, or accommodate varying facility readiness. 
Several commenters also stated that the web application, FHIR[supreg] 
APIs, implementation guides, specifications, sandbox environments, and 
training should be available early enough for facilities and vendors to 
evaluate, test, train, and implement workflows before mandatory 
reporting.
    Response: We appreciate the commenters' support for multiple 
submission methods, and the recommendation that we provide sufficient 
time for IPFs and vendors to implement and test data submission 
solutions. We are updating the DEL FHIR[supreg] Implementation Guide 
and the iQIES FHIR[supreg] Receiving System Implementation Guide based 
on the modified policies in this final rule as soon as feasible, 
between six to twelve months in advance of the voluntary reporting 
period that begins October 1, 2027. In addition, we plan to make 
available testing and validation tools, so that vendors and IPFs will 
be able to verify that files are being transmitted in the proper format 
to be received by CMS systems. We also note that, as described in 
section V.C.4.b. of this final rule, we are finalizing a policy in 
which IPFs may begin voluntary reporting of the IPF-PAI beginning 
October 1, 2027. Mandatory reporting of the IPF-PAI then begins on July 
1, 2028 for Q3 CY 2028. Assessments submitted in Q3 and Q4 2028 will be 
considered for the FY 2030 payment determination. We expect that the 
voluntary period will provide an opportunity to address any significant 
challenges encountered during the data submission process.
    Comment: Many commenters stated concerns that IPFs and behavioral 
health lag behind other healthcare settings with regard to EHR adoption 
and interoperability readiness. Several commenters attribute this to 
IPFs being left out of federal EHR incentive programs. The commenters 
said that required FHIR[supreg]-based reporting beginning October 1, 
2027 may be premature for the IPF setting and would require time for 
specification development, EHR development, training, workflow testing, 
submission validation, and identification of problems. Many commenters 
recommended delaying, phasing, or extending implementation.
    Response: By offering PARIT, the free web app, an IPF can meet the 
IPF-PAI submission requirements regardless of its existing EHR 
capabilities. That is, PARIT uses the same FHIR[supreg] APIs specified 
in this rule that EHR vendors or third-party intermediaries would use 
to submit IPF-PAI data to CMS. By providing a web-based user interface 
to these APIs, PARIT enables an IPF to submit IPF-PAI data without 
needing an EHR, EHR development, or its own implementation of the 
FHIR[supreg] specifications or a FHIR[supreg]-based reporting system. 
However, whether an IPF chooses to utilize the PARIT web application or 
FHIR API integration, we recommend training of relevant staff, testing, 
and submission validation. We note that, as described in section 
V.C.4.b. of this final rule, we are finalizing a policy in which IPFs 
may begin voluntary reporting of the IPF-PAI beginning October 1, 2027, 
with mandatory reporting beginning July 1, 2028, which is a phased 
implementation responsive to commenters' recommendations. While not all 
provider types were eligible for EHR meaningful use incentives payments

[[Page 48568]]

under the Health Information Technology for Economic and Clinical 
Health (HITECH) Act and this may partly explain the slower start for 
many IPFs, survey data from 2024 found that approximately 78 percent of 
psychiatric hospitals and 86 percent of separate psychiatric units of 
general hospitals use EHRs.\39\ This indicates that although EHR 
adoption among IPFs is lower relative to other hospital provider types 
and often occurs alongside paper-based documentation, many IPFs have 
implemented EHRs.

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

    Comment: Several commenters stated that IPF-PAI data may be 
difficult to retrieve from their facilities' EHR, as currently 
configured, and that the manual entry, manual aggregation, or temporary 
web app processes that would be required may necessitate additional 
staffing. A few commenters recommended that we consider technological 
solutions or data-extraction mechanisms that use assessment data 
already documented in EHRs, automate extraction as much as possible, 
work with existing EHR infrastructure, and avoid additional 
implementation costs for IPFs.
    Response: We acknowledge the systems and data extraction challenges 
that facilities may face in their initial implementation of the IPF-
PAI. We took these challenges into account in our decision to develop 
FHIR APIs to support the collection and reporting of the IPF-PAI. We 
understand that the transition to automated data reporting via the FHIR 
APIs will take time, and that IPFs may need to integrate IPF-PAI 
assessment items in their EHRs and in their clinical workflows in a way 
that will avoid an ongoing need for manual data extraction. We note 
that we are providing PARIT, the free web app for data submission, as 
an interim solution for IPFs that are not yet ready to adopt EHR-
integrated technical solutions for data collection and reporting. We 
intend to provide robust training, technical documentation, and 
technical help desk support to help IPFs and health IT vendors, and 
staff understand and operationalize the extraction of EHR data and 
submission required by the IPF-PAI.
    Comment: A few commenters recommended implementation guides, sample 
data, regular feedback channels, technical collaboration with EHR 
vendors and implementers, production-like testing, consistent iQIES-
connected authentication and endpoint conventions, and bulk or batch 
submission capability. A few commenters also expressed concern about 
submission accuracy, payment penalties, workflow disruption, compliance 
risk, or data integrity if implementation was rushed or guidance was 
unclear. A few commenters stated that the new data collection and 
submission process would create administrative burden, particularly for 
facilities submitting through FHIR[supreg] for the first time, meeting 
a high data threshold, or managing accuracy, payment penalty, 
compliance, and data integrity concerns.
    Response: We agree that technical resources and communication 
mechanisms are important for the successful implementation of the IPF-
PAI. In addition to the DEL FHIR[supreg] Implementation Guide and the 
iQIES FHIR[supreg] Receiving System Implementation Guide, we will 
provide comprehensive documentation, engagement opportunities, and 
access to a technical help desk to help resolve issues with submitting 
FHIR[supreg] data to CMS systems. Regarding authentication and endpoint 
conventions, there are two endpoints, one for the DEL, to support 
retrieval of the assessment items, and one for iQIES, to support the 
assessment data submission. The DEL endpoint does not require 
authentication, as it provides the assessment items only and does not 
handle any user-specific or patient information. The iQIES endpoint 
requires HARP authentication to associate the user with the IPF or its 
authorized vendor(s) and endorse authorization controls regarding what 
users can see, edit, and submit. For the initial version of the IPF-
PAI, CMS' FHIR[supreg] receiving system will not be able to support 
batch submission, but we will actively evaluate this functionality. We 
will provide more information on validation tools and other resources 
after the publication of this final rule.
    We recognize commenters' concerns regarding submission accuracy, 
workflow impacts, compliance risk, data integrity, and potential 
payment implications. We believe that the advance availability of the 
IPF-PAI implementation guides, together with the release of training 
and educational materials at least 6 months before voluntary reporting 
begins, will provide stakeholders with sufficient opportunity to 
prepare for implementation and support accurate and timely data 
submission. We are allowing for three quarters of voluntary data 
reporting prior to the first mandatory reporting, which will be in the 
third quarter of 2028. Additionally, CMS also anticipates using 
implementation support resources, such as the Patient Information 
Quality Improvement (PIQI) Framework,\40\ to help providers and vendors 
identify and address issues related to data accuracy, completeness, 
structure, and conformance before production submission. We will 
continue to engage with stakeholders and consider operational feedback 
throughout the implementation process. We note we are finalizing a 
policy to begin mandatory reporting with a 50 percent compliance 
threshold, increasing to 70 percent beginning with the CY 2030 
reporting period (for the FY 2032 payment determination), which should 
alleviate commenters' concerns about an immediate burden to meet a high 
level of completion before the IPF has had time to adjust.

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

    Final Decision: After consideration of the comments received, we 
are finalizing the FHIR[supreg] API method of data submission for IPF-
PAI data as proposed. As discussed in section V.C.4., we are 
implementing the IPF-PAI on October 1, 2027 with three quarters of 
voluntary data submission. Mandatory reporting will begin on July 1, 
2028. We intend that the voluntary data submission period will provide 
IPFs and their health IT vendors with sufficient time to develop and 
implement data submission processes.
    Additionally, in the FY 2027 IPF PPS proposed rule (91 FR 17746), 
we invited public comment on ways that CMS could reduce burden in 
implementing the IPF-PAI. For example, we asked if any of the 
requirements currently proposed for the IPF-PAI are duplicative of any 
other CMS reporting and recordkeeping requirements.
    We received public comments on this issue which we addressed in the 
sections of this final rule to which they most directly applied.
5. Maintenance of Technical Specifications for the IPF-PAI
a. Background
    In the FY 2013 IPPS/LTCH PPS final rule, we adopted a policy to use 
subregulatory process to make non-substantive updates to measures used 
in the IPF Quality Reporting Program, to make the determination of what 
constitutes a substantive versus a non-substantive change on a case-by-
case basis, and to continue to use rulemaking to adopt substantive 
updates (77 FR 53653). In addition, in the FY 2014 IPPS/LTCH PPS final 
rule, we established a policy under which we provide and maintain 
information to

[[Page 48569]]

support collection of measures used in the program (78 FR 50896). As 
part of this policy, we provide a user manual with links to measure 
specifications, data abstraction information, data submission 
information, and other information necessary for IPFs to participate in 
the IPF Quality Reporting Program. We maintain this manual at the IPF 
Quality Reporting Program Quality Net website at https://qualitynet.cms.gov/ipf/specifications-manuals. In addition, we update 
technical specifications in this manual periodically, notify program 
participants of changes, and strive to provide sufficient time to allow 
users to respond to changes.
b. Policy for Maintenance of Technical Specifications for the IPF-PAI
    In alignment with our policy for maintaining the IPF Quality 
Reporting Program specifications manual for quality measures, and as 
described in section IV.C.5.a of the FY 2027 IPF PPS proposed rule (91 
FR 17746), we proposed that non-substantive updates to the technical 
specifications for the IPF-PAI would be made through subregulatory 
mechanisms such as website postings and listserv messaging. Non-
substantive updates could include minor changes to data collection or 
submission specifications which might be required to align with updates 
to HL7[supreg] FHIR[supreg] or other health IT standards, and will be 
determined on a case-by-case basis. We stated that we will provide 
notification of any future changes to the CMS designated system and the 
required format for IPF-PAI data submission designated by CMS to IPFs 
and vendors using subregulatory mechanisms including updates of 
technical specifications in the Guidance Manual and Implementation 
Guides as well as through our regular program communication channels 
such as website postings, listserv messaging, and webinars. We 
clarified that substantive changes to the IPF-PAI, such as the addition 
or removal of data categories or assessment items, or changes in the 
data collection deadlines, will be done through rulemaking.
    We received public comments on this proposal.
    Comment: Several commenters expressed concerns about CMS' statement 
that the IPF-PAI may be modified in future rulemaking. The commenters 
stated that modifications would create burden related to system 
updates, retraining, workflow redesign, and reconfiguration.
    Response: We acknowledge that future changes to the requirements 
for IPF-PAI data may result in burden for IPFs. We strive to collect 
meaningful data about inpatient psychiatric stays while minimizing 
burden. We note that if we make subregulatory technical updates they 
will be changes required to align with updates to FHIR[supreg] or other 
health IT standards. In the case of modifications through future 
rulemaking, we will carefully evaluate the impact of these changes with 
respect to IPF burden.
    Comment: A few commenters recommended limiting or stabilizing 
future technical changes, including keeping IPF-PAI changes minor for 
at least three years, limiting FHIR[supreg] changes, and standardizing 
FHIR[supreg] technology across vendors and data recipients. A commenter 
also recommended expanding communication methods to keep IPFs and 
vendors informed, avoiding sub-regulatory processes for large or 
impactful changes, and preserving adequate testing and implementation 
timelines.
    Response: We appreciate these comments. We understand that IPFs and 
vendors need clear guidance and time to incorporate the IPF-PAI. We 
will continue to provide guidance manuals, implementation materials, 
webinars, listserv updates, and other technical support. We also intend 
to make substantive changes through future notice-and-comment 
rulemaking, while keeping technical updates as limited and targeted as 
possible so the IPF-PAI can be implemented in a stable manner.
    Comment: A commenter recommended detailed implementation guidance 
on FHIR[supreg] API privacy and security features, stating that IPFs 
must be able to evaluate the privacy and security architecture before 
integrating technology that may retrieve and transmit sensitive 
behavioral health information.
    Response: We appreciate this comment and recognize the importance 
of privacy and security. CMS will provide technical documentation and a 
technical help desk so that IPFs and vendors can understand the 
submission architecture and assess readiness before implementation. We 
also expect that IPFs and vendors will ensure that FHIR[supreg]-based 
submission operates with applicable privacy and security requirements 
for IPFs. We will continue to refine operational guidance as necessary 
through future technical updates and rulemaking.
    Final Decision: After consideration of the comments received, we 
are finalizing our policy for maintenance of technical specifications 
for the IPF-PAI as proposed.

VI. Collection of Information Requirements

    Under the Paperwork Reduction Act of 1995 (PRA), 44 U.S.C. 3501-
3520, we are required to provide notice in the Federal Register and 
solicit public comment before a collection of information requirement 
is submitted to the Office of Management and Budget (OMB) for review 
and approval. To fairly evaluate whether an information collection 
should be approved by OMB, 44 U.S.C. 3506(c)(2)(A) requires that we 
solicit comment on the following issues:
     The need for the information collection and its usefulness 
in carrying out the proper functions of our agency.
     The accuracy of our estimate of the information collection 
burden.
     The quality, utility, and clarity of the information to be 
collected.
     Recommendations to minimize the information collection 
burden on the affected public, including automated collection 
techniques.
    The following changes will be submitted to OMB for review under 
control number 0938-1171 (CMS-10432). In addition, we are submitting a 
Paperwork Reduction Act package for the IPF Patient Assessment 
Instrument (IPF-PAI) required by section 4125(b)(1) of the Consolidated 
Appropriations Act of 2023, to OMB for review under a new control 
number.
    In section VI.C.1. of this final rule, we restate our currently 
approved burden estimates. In section VI.C.2. of this final rule, we 
estimate the changes in burden associated with the update to more 
recent wage rates. In section VI.C.3. of this final rule, we discuss 
the policies in this final rule that will impact information collection 
burden.

A. Wage Estimates

    In the FY 2026 IPF PPS final rule, we utilized the median hourly 
wage rate of $27.69 for Medical Records Specialists, in accordance with 
the Bureau of Labor Statistics (BLS), to calculate our burden estimates 
for the IPF Quality Reporting Program (90 FR 37667). In the FY 2027 IPF 
PPS proposed rule, using the most recent data from the BLS for medical 
records specialists (SOC 29-2072), entitled, the May 2024 Occupational 
Employment and Wage Estimates, we used the median hourly wage for 
medical records specialists for the industry, ``general medical and 
surgical hospitals,'' (Industry# 622100) which is $27.53.\41\ We stated 
the industry of

[[Page 48570]]

``general medical and surgical hospitals'' is more specific to the IPF 
setting for use in our calculations compared to other industries under 
medical records specialists, such as ``office of physicians'' or 
``nursing care facilities.'' We calculated the cost of overhead, 
including fringe benefits, at 100 percent of the median hourly wage, 
consistent with previous years. This is necessarily a rough adjustment, 
both because fringe benefits and overhead costs vary significantly by 
employer and methods of estimating these costs vary widely in the 
literature. Nonetheless, we believe that doubling the hourly wage rate 
($27.53 x 2 = $55.06) to estimate total cost is a reasonably accurate 
estimation method. Unless otherwise specified, we will calculate cost 
burden to hospitals using a wage plus benefits estimate of $55.06 per 
hour throughout the discussion in this section of this final rule. As 
noted in the FY 2027 IPF PPS proposed rule, although BLS released 
updated wage rates after the proposed rule appeared in the Federal 
Register and before this final rule will appear in the Federal 
Register, we are maintaining the wage rates used in the proposed rule 
(91 FR 17746).

    Some of the activities previously finalized for the IPF Quality 
Reporting Program require patients' time and attention, such as 
responding to survey questions. In the FY 2026 IPF PPS final rule, we 
estimated the hourly wage rate for these activities to be $25.63/hr (90 
FR 37667). We are updating that estimate to a post-tax wage of $25.89/
hr. The Valuing Time in U.S. Department of Health and Human Services 
Regulatory Impact Analyses: Conceptual Framework and Best Practices 
identifies the approach for valuing time when individuals undertake 
activities on their own time. In the FY 2027 IPF PPS proposed rule, we 
derived the costs for patients using the usual weekly earnings of wage 
and salary workers of $1,204, divided by 40 hours to calculate an 
hourly pre-tax wage rate of $30.10/hr. We adjusted this rate downwards 
by an estimate of the effective tax rate for median income households 
of about 14 percent calculated by comparing pre and post-tax income, 
resulting in the post-tax hourly wage rate of $25.89/hr. Unlike state 
and private sector wage adjustments, we are not adjusting beneficiary 
wages for fringe benefits and other indirect costs since the 
individuals' activities, if any, would occur outside the scope of their 
employment.

B. Estimates of the Number of Respondents

    In the FY 2026 IPF PPS final rule, we based estimates of 
information collection burden on the assumption that 1,596 IPFs would 
report data for 1,261 discharges, on average per facility, for the IPF 
Quality Reporting Program in CY 2026 and subsequent years. For this 
final rule, based on data from the FY 2027 payment determination, we 
are updating our assumption and estimate that 1,564 IPFs will report 
data for an average of 1,342 discharges annually per facility for the 
IPF Quality Reporting Program in CY 2027 and subsequent years.

C. Information Collection Requirements for the IPF Quality Reporting 
Program

1. Previously Finalized IPF Quality Reporting Program Estimates
    For the purposes of calculating burden, we attribute the costs to 
the year in which the costs begin. Under our previously finalized 
policies, data submission for the measures that affect the FY 2029 
payment determination occurs during CY 2028 and generally reflects care 
provided during CY 2027. Our currently approved burden for CY 2027 is 
set forth in Table 11.

2. Updates Due to More Recent Information
    In section VI.A. of this final rule, we describe our updated wage 
rates which decrease from $55.38/hr to $55.06/hr (a decrease of $0.32/
hr) for activities performed by Medical Records Specialists and 
increase from $25.63/hr to $25.89/hr (an increase of $0.26/hr) for 
activities performed by individuals. The effects of these updates are 
set forth in Table 12.

[[Page 48573]]

[GRAPHIC] [TIFF OMITTED] TR31JY26.035

    In section VI.B. of this final rule, we describe our updated 
assumptions of the number of responses which decrease from 1,596 
facilities to 1,564 (a decrease of 32) and an increase in the number of 
annual discharges per IPF from 1,261 to 1,342 (an increase of 81). The 
effects of these updates are set forth in Table 13.
[GRAPHIC] [TIFF OMITTED] TR31JY26.036

    The total net impact of updates due to more recent information is 
an increase of 10,308 hours and $601,464 annually.
3. Updates Due to Policies Finalized in This Rule
    In section V.B.1. of this final rule, we are removing the Alcohol 
Use Brief Intervention Provided or Offered (SUB-2) and subset Alcohol 
Use Brief Intervention (SUB-2a) measure from the IPF Quality Reporting 
Program beginning with the FY 2028 payment determination and subsequent 
years. This measure and the associated information collection burden 
were previously finalized in the FY 2016 IPF PPS final rule and are 
approved under OMB control number 0938-1171 (expiration date February 
29, 2028) (80 FR 46699 through 46701 and 46720 through 46721). Using 
the currently approved burden estimate under OMB control number 0938-
1171 of 15 minutes (0.25 hours) per case per IPF, we estimate this 
policy will result in a decrease in burden of 238,119 hours (0.25 hours 
x 609 cases x 1,564 IPFs) at a savings of $13,110,832 (238,119 x 
$55.06/hour) across all 1,564 IPFs.
    In section V.B.2. of this final rule, we are removing the Tobacco 
Use Treatment Provided or Offered at Discharge (TOB-3) and subset 
Tobacco Use Treatment at Discharge (TOB-3a) measure from the IPF 
Quality Reporting Program beginning with the FY 2028 payment 
determination and subsequent years. This measure and the associated 
information collection burden were previously finalized in the FY 2016 
IPF PPS final rule and are approved under OMB control number 0938-1171 
(expiration date February 29, 2028) (80 FR 46696 through 46701 and 
46720 through 46721). Using the currently approved burden estimate 
under OMB control number 0938-1171 of 15 minutes (0.25 hours) per case 
per IPF, we estimate this policy will result in a decrease in burden of 
238,119 hours

[[Page 48574]]

(0.25 hours x 609 cases x 1,564 IPFs) at a savings of $13,110,832 
(238,119 x $55.06/hour) across all 1,564 IPFs.
    In section V.C. of this final rule, we are modifying our proposal 
to implement the IPF-PAI beginning with Quarter 4 of the CY 2027 
reporting period/FY 2029 payment determination, and instead are 
finalizing voluntary data submission beginning October 1, 2027, 
followed by mandatory data submission beginning July 1, 2028. The IPF-
PAI consists of two assessments, one administered at the time of 
patient admission and the other administered at discharge. As proposed 
in the FY 2027 IPF PPS proposed rule, the IPF-PAI consisted of 26 and 
23 assessment item parts at admission and discharge, respectively (91 
FR 17740 through 17743). In Section V.C.3., we finalized a modification 
of the proposal of assessment items for the IPF-PAI that reduces the 
number of assessment items: we will require the Mobility assessment 
item at Admission only--rather than at Admission and Discharge, as 
proposed; we will require the SSTI assessment item at Discharge only--
rather than at both Admission and Discharge; and we are not finalizing 
the inclusion of SSN on this initial version of the IPF-PAI. These 
modifications reduce the number of assessment item parts by 9 (1 
assessment item part for Mobility, 6 assessment item parts for SSTI, 
and 2 assessment item parts for SSN [at Admission and Discharge]). As 
finalized, the IPF-PAI consists of 19 assessment item parts at 
Admission and 21 assessment item parts at Discharge. For the purpose of 
estimating collection of information burden, we estimate that each 
assessment item part in the IPF-PAI will require approximately 0.3 
minutes (18 seconds) to complete. Our estimate of 0.3 minutes is 
similar to estimates used in other CMS PAI data collections and is 
supported by the IPF-PAI field (beta) test. In field testing, which 
used volunteer assessors and a convenience sample of patients, 
assessors completed the beta test assessments, which contained 86 
assessment item parts at Admission and 85 assessment parts at 
Discharge, in a median time of 13 minutes, or approximately 0.15 
minutes per assessment item part; time per assessment item part was 
slightly higher for admission assessments (median time to complete of 
16 minutes, or 0.19 minutes per assessment item part) than for 
discharges (median time to complete of 11 minutes, or 0.13 minutes). We 
proposed using 0.3 minutes for each assessment item part and estimated 
that the IPF-PAI would require 14.7 minutes (0.3 minutes x 49 
assessment item parts) or 0.245 hours per patient. In Section V.C.3., 
we finalized a modification of the proposal of assessment items for the 
IPF-PAI that reduces the number of assessment item parts in the IPF-PAI 
to 40 for admission and discharge combined. Under finalized policies, 
using 0.3 minutes for each assessment item part, we estimate that the 
IPF-PAI will require 12 minutes (0.3 minutes x 40 assessment item 
parts) or 0.2 hours per patient.
    We also assumed the IPF-PAI will be completed by a variety of 
clinical or support staff. We estimated that approximately 50 percent 
of data collected associated with the IPF-PAI will be completed by 
Medical Records Specialists with the remaining 50 percent being split 
equally by Registered Nurses (RNs), Licensed Practical/Licensed 
Vocational Nurses (LP/LVNs), and Mental Health and Substance Abuse 
Social Workers. Similar to our calculation of the wage rate for Medical 
Records Specialists discussed in section VI.A. of this final rule, we 
utilize the BLS median hourly wage rates of $46.74/hour, $28.09/hour, 
and $37.49/hour for RNs (SOC 29-1141), LP/LVNs (SOC 29-2061), and 
Mental Health and Substance Abuse Social Workers (SOC 21-1023) for the 
industry, ``general medical and surgical hospitals'' (Industry #622100) 
and calculated the cost of overhead, including fringe benefits, at 100 
percent of the median hourly wage.\42\ As a result, we calculate a 
weighted average labor rate of $65.04/hour [($55.06/hour x 50 percent) 
+ ($46.74/hour x 2 x 16.7 percent) + ($28.09/hour x 2 x 16.7 percent) + 
($37.49/hour x 2 x 16.7 percent)]. To calculate the number of patients 
for which the IPF-PAI will be administered, we multiply the number of 
IPFs by the average discharges per IPF, for a total of 2,098,888 
patients (1,564 IPFs x 1,342 discharges/IPF). We estimate this policy 
will result in an increase in burden of 419,778 hours annually (0.2 
hours x 2,098,888 patients) at a cost of $27,302,361 (419,778 x $65.04/
hour), beginning with the CY 2029 reporting period which is the first 
full reporting period that the IPF-PAI will be implemented with 
mandatory data submission. For voluntary data submission in Quarter 4 
of the CY 2027 reporting period and Quarters 1 and 2 of the CY 2028 
reporting period, we assume 50 percent of IPFs will administer the IPF-
PAI to 25 percent of patients on average, resulting in a total number 
of 65,590 patients ((50 percent x 1,564 IPFs) x (25 percent x ((1,342 
discharges/IPF / 4 quarters) x 1 quarter))) and 131,181 patients ((50 
percent x 1,564 IPFs) x (25 percent x ((1,342 discharges/IPF / 4 
quarters) x 2 quarters))) in the CY 2027 and CY 2028 reporting periods, 
respectively. For the CY 2027 reporting period, we estimate this policy 
will result in an increase in burden of 13,118 hours (0.2 hours x 
65,590 patients) at a cost of $853,195 (13,118 hours x $65.04/hour). 
For mandatory data submission in Quarters 3 and 4 of the CY 2028 
reporting period, we estimate the number of patients for which the IPF-
PAI will be administered to be 50 percent of the annual total of 
2,098,888 patients, or 1,049,444 patients (2,098,888 patients x 50 
percent). We note that 50 percent is because it is mandatory for half 
of the year. As a result, for the CY 2028 reporting period, we estimate 
this policy will result in an increase in burden of 236,125 hours (0.2 
hours x (1,049,444 + 131,181 patients)) at a cost of $15,357,570 
(236,125 hours x $65.04/hour). Because IPF-PAI data will be submitted 
using the same web application or FHIR[supreg] API used to enter 
assessment item responses into the assessment, the time to transmit 
data to CMS is negligible, and therefore we assume no additional burden 
for IPFs to submit IPF-PAI data. We note that our burden estimate 
assumes manual entry of patient assessment data (that is, entry using 
the web application) for all IPFs and therefore represents the most 
conservative estimate. We expect that some IPFs will utilize the 
FHIR[supreg] API and related guidance to partially or fully automate 
their data collection and submission process, thereby reducing the 
collection of information burden.

4. Summary of Information Collection Requirements and Associated Burden
    In this final rule, we are finalizing as proposed removal of the 
Alcohol Use Brief Intervention Provided or Offered (SUB-2) and subset 
Alcohol Use Brief Intervention (SUB-2a) measure, as well as the Tobacco 
Use Treatment Provided or Offered at Discharge (TOB-3) and subset 
Tobacco Use Treatment at Discharge (TOB-3a) measure beginning with the 
CY 2026 reporting period/FY 2028 payment determination. In the FY 2027 
IPF PPS proposed rule, we proposed to implement the IPF-PAI beginning 
with Quarter 4 of the CY 2027 reporting period/FY 2029 payment 
determination and assumed the 26 item admission assessment and 23 item 
discharge assessment would require a

[[Page 48575]]

total of 14.7 minutes per patient to complete. As discussed in this 
final rule, we are removing a total of 9 assessment items and 
decreasing burden per patient to 12 minutes, while also finalizing 
implementation of the IPF-PAI with voluntary data submission beginning 
October 1, 2027, followed by mandatory data submission beginning July 
1, 2028.
    As a result of policies finalized in this rule, beginning with the 
CY 2029 reporting period/FY 2031 payment determination when all 
finalized policies will be mandatory for a full CY, the net information 
collection burden associated with the IPF Quality Reporting Program is 
estimated to decrease by 56,460 hours and increase $1,080,697 in costs 
associated with these policies.
    We will submit a revised PRA package for OMB control number 0938-
1171 reflecting the information collection burden decrease of 476,238 
hours at a cost of $26,221,664 associated with removal of the SUB-2/2a 
and TOB-3/3a measures. We will also submit a new PRA package under a 
new OMB control number reflecting the information collection burden of 
419,778 hours at a cost of $27,302,361 associated with implementation 
of the IPF-PAI.

BILLING CODE 4169-69-C
    We received comments on this proposal.
    Comment: A commenter stated that the burden estimate was generally 
appropriate once the proposed web app and FHIR[supreg] interfaces were 
available.
    Response: We thank the commenter for this feedback. Our burden 
estimation process was based on field (beta) test data, and we intend 
it to reflect typical clinical practice. We will monitor and update 
burden estimates associated with the new PRA package for the IPF-PAI as 
needed as IPFs gain more experience reporting IPF-PAI data.
    Comment: Several commenters stated that field (beta) test results 
could not be applied to the final instrument and that the 14.7-minute 
estimate understated complexity.
    Response: With respect to time-to-complete estimates, the field 
(beta) test informed the burden estimate by providing total times for 
data collection across the entire test instrument, which we used to 
calculate the average per-assessment item part estimate. We maintain 
that our time estimate for each assessment item part is valid; we used 
only the portions of the field (beta) test in which IPF staff were 
assessing real patients.
    Comment: Many commenters stated that CMS' burden estimate focused 
too narrowly on item completion time and understated the real-world 
effort needed for EHR reconfiguration, vendor work, staff training, 
workflow redesign, data correction, internal validation, quality 
assurance, FHIR[supreg] or iQIES submission, reporting steps, 
interoperability needs, and ongoing compliance monitoring. Several 
commenters stated that treating the IPF-PAI like a single IPF Quality 
Reporting Program measure understated the number of assessments.
    Response: We recognize that there will be costs associated with 
implementing the IPF-PAI that are not accounted for in these estimates 
of collection of information. Consistent with PRA requirements, our 
collection of information estimates are limited to recurring data 
collection costs. These estimates were calculated using data collected 
during the field (beta) test in which IPF clinicians assessed real 
patients. These estimates do not extend to workforce training and other 
start-up costs, nor to any data monitoring activities that IPFs may 
choose to conduct. We note that the option of automated or semi-
automated reporting using FHIR[supreg] APIs, for IPFs that have or 
develop that capability, is likely to reduce actual collection of 
information burden. We acknowledge the systems and data extraction 
challenges that facilities may face in their initial implementation of 
the IPF-PAI. We took these challenges into account in our decision to 
develop FHIR APIs to support the collection and reporting of the IPF-
PAI. We understand that the transition to automated data reporting via 
the FHIR APIs will take time, and that IPFs may need to integrate IPF-
PAI assessment items in their EHRs and in their clinical workflows in a 
way that will avoid an ongoing need for manual data extraction. We note 
that we are providing PARIT, the free web app for data submission, as 
an interim solution for IPFs that are not yet ready to adopt EHR-
integrated technical solutions for data collection and reporting. We 
intend to provide robust training, technical documentation, and 
technical help desk support to help IPFs and health IT vendors, and 
staff understand and operationalize the extraction of EHR data and 
submission required by the IPF-PAI. In addition, we are finalizing a 
delay in mandatory reporting, to July 1, 2028, and allowing IPFs three 
quarters of voluntary data submission beginning October 1, 2027. We 
intend for this period to allow IPFs more flexibility on when and how 
they integrate the IPF-PAI into their workflows and systems in a way 
that minimizes burden.

VII. Regulatory Impact Analysis

A. Statement of Need

    This rule updates the prospective payment rates for Medicare 
inpatient hospital services provided by IPFs for discharges occurring 
during FY 2027 (October 1, 2026, through September 30, 2027). We 
applied the 2021-based IPF market basket increase for FY 2027 of 3.2 
percent, reduced by the productivity adjustment of 0.9 percentage point 
as required by section 1886(s)(2)(A)(i) of the Act for a total FY 2027 
payment rate update of 2.3 percent. In this final rule, we updated the 
outlier fixed dollar loss threshold amount, updated the IPF labor-
related share, and updated the IPF wage index to reflect the FY 2027 
hospital inpatient wage index. Section 1886(s)(4) of the Act requires 
IPFs to report data in accordance with the requirements of the IPF 
Quality Reporting Program for purposes of measuring and making publicly 
available information on health care quality; and links the quality 
data submission to the annual applicable percentage increase.

B. Overall Impact

    We have examined the impacts of this rule as required by Executive 
Order 12866, ``Regulatory Planning and Review''; Executive Order 13132, 
``Federalism''; Executive Order 13563, ``Improving Regulation and 
Regulatory Review''; Executive Order 14192, ``Unleashing Prosperity 
Through Deregulation''; the Regulatory Flexibility Act (RFA) (Pub. L. 
96-354); section 1102(b) of the Social Security Act; and section 202 of 
the Unfunded Mandates Reform Act of 1995 (Pub. L. 104-4); and the 
Congressional Review Act (5 U.S.C. 801-808).
    Executive Orders 12866 and 13563 direct agencies to assess all 
costs and benefits of available regulatory alternatives and, if 
regulation is necessary, to select those regulatory approaches that 
maximize net benefits (including potential economic, environmental, 
public health and safety, and other advantages; distributive impacts; 
and equity). Section 3(f) of Executive Order 12866 defines a 
``significant regulatory action'' as any regulatory action that is 
likely to result in a rule that may: (1) have an annual effect on the 
economy of $100 million or more or adversely affect in a material way 
the economy, a sector of the economy, productivity, competition, jobs, 
the environment, public health or safety, or State, local, or tribal 
governments or communities; (2) create a serious inconsistency or 
otherwise interfere with an action taken or planned by another agency; 
(3) materially alter the budgetary impact of entitlements, grants, user 
fees, or loan programs or the rights and obligations of recipients 
thereof; or (4) raise novel legal or policy issues arising out of legal 
mandates, or the President's priorities.
    A regulatory impact analysis (RIA) must be prepared for a 
regulatory action that is significant under section 3(f)(1) of E.O. 
12866. We estimate that the total impact of these changes for FY 2027 
payments compared to FY 2026 payments will be an increase of 
approximately $60 million. This reflects a $60 million increase from 
the update to the payment rates (+$80 million from the 2021-based IPF 
market basket increase of 3.2 percent, and -$20 million for the 
productivity adjustment of 0.9 percentage point). Outlier payments are 
estimated to remain at 2.0 percent of total estimated IPF payments in 
FY 2027.
    Based on our estimates, OMB's Office of Information and Regulatory 
Affairs has determined that this rulemaking is ``significant'' under 
section 3(f) of Executive Order 12866, though not significant under 
section 3(f)(1). Nevertheless, because of the potentially substantial 
impact to IPF providers, we have prepared an RIA that to the best of 
our ability presents the costs and benefits of the rulemaking. OMB has 
reviewed these final regulations, and the Departments have provided the 
following assessment of their impact.

C. Detailed Economic Analysis

    In this section, we discuss the historical background of the IPF 
PPS and the impact of the final rule on the Federal Medicare budget and 
on IPFs.
1. Budgetary Impact
    As discussed in the RY 2005 and RY 2007 IPF PPS final rules, we 
applied a budget neutrality factor to the Federal per diem base rate 
and ECT payment per treatment to ensure that total estimated payments 
under the IPF PPS in the implementation period would equal the amount 
that would have been paid if the IPF PPS had not been implemented. This 
budget neutrality factor included the following components: outlier 
adjustment, stop-loss adjustment, and the behavioral offset. As 
discussed in the RY 2009 IPF PPS notice (73 FR 25711), the stop-loss 
adjustment is no longer applicable under the IPF PPS.
    As discussed in section IV.D.1.c. of this final rule, we updated 
the wage index and labor-related share in a budget neutral manner by 
applying a wage index budget neutrality factor to the Federal per diem 
base rate and ECT payment per treatment. Therefore, the budgetary 
impact to the Medicare program of this final rule is due to the market 
basket increase for FY 2027 of 3.2 percent (see section IV.A.2. of this 
final rule) reduced by the productivity adjustment of 0.9 percentage 
point required by section 1886(s)(2)(A)(i) of the Act and the update to 
the outlier fixed dollar loss threshold amount.
    We estimate that the impact of the FY 2027 IPF PPS final rule would 
be a net increase of $60 million in payments to IPF providers. This 
reflects an estimated $60 million increase from the update to the 
payment rates. There is no impact as a result of the update to the 
outlier threshold amount as noted earlier. This estimate does not 
include the implementation of the required 2.0 percentage point 
reduction of the market basket update factor for any IPF that fails to 
meet the IPF Quality Reporting requirements (as discussed in section 
V.B.3. of this final rule).
2. Impact on Providers
    To show the impact on providers of the changes to the IPF PPS 
discussed in this final rule, we compared estimated payments under the 
final IPF PPS rates and factors for FY 2027 versus those under FY 2026. 
We determined the percent change in the estimated FY 2027 IPF PPS 
payments compared to the estimated FY 2026 IPF PPS payments for each 
category of IPFs. In addition, for each category of IPFs, we have 
included the estimated percent change in payments resulting from the 
update to the outlier fixed dollar loss threshold amount; the updated 
wage index data and labor-related share; and the market basket increase 
for FY 2027, as reduced by the productivity adjustment according to 
section 1886(s)(2)(A)(i) of the Act.
    To illustrate the impacts of the FY 2027 changes to the IPF PPS 
discussed in this final rule, our analysis begins with FY 2025 IPF PPS 
claims (based on the 2025 MedPAR claims, December 2025 update). We 
estimated FY 2026 IPF PPS payments using these 2025 claims, the 
finalized FY 2026 IPF PPS Federal per diem base rate and ECT per 
treatment amount, and the finalized FY 2026 IPF PPS patient- and 
facility-level adjustment factors (as published in the FY 2026 IPF PPS 
final rule (90 FR 37628)). We then estimated the FY 2026 outlier 
payments based on these simulated FY 2026 IPF PPS payments using the 
same methodology as finalized in the FY 2026 IPF PPS final rule (90 FR 
37653 and 37654) where total outlier payments are maintained at 2 
percent of total estimated FY 2026 IPF PPS payments.

[[Page 48578]]

    Each of the following changes is added incrementally to this 
baseline model in order to isolate the effects of each change:
     The update to the outlier fixed dollar loss threshold 
amount.
     The FY 2027 IPF wage index and the FY 2027 labor-related 
share.
     The IPF market basket increase for FY 2027 of 3.2 percent 
reduced by the productivity adjustment of 0.9 percentage point in 
accordance with section 1886(s)(2)(A)(i) of the Act for a FY 2027 
payment rate update of 2.3 percent.
    Our column comparison in Table 16 illustrates the percent change in 
payments from FY 2026 (that is, October 1, 2025, to September 30, 2026) 
to FY 2027 (that is, October 1, 2026, to September 30, 2027) including 
all the final payment policy changes.

BILLING CODE 4169-69-C
3. Impact Results
    Table 16 displays the results of our analysis. The table groups 
IPFs into the categories listed here based on characteristics provided 
in the Provider of Services file, the IPF PSF, and cost report data 
from the Healthcare Cost Report Information System:
     Facility Type.
     Location.
     Teaching Status Adjustment.
     Census Region.
     Size.
    The top row of Table 16 shows the overall impact on the 1,336 IPFs 
included in the analysis. In column 2, we present the number of 
facilities of each type that had information available in the PSF and 
had claims in the MedPAR dataset for FY 2025.
    In column 3, we present the effects of the update to the outlier 
fixed dollar loss threshold amount. We estimate that IPF outlier 
payments as a percentage of total IPF payments are 2.0 percent in FY 
2026. However, as discussed in section IV.E.c. of this final rule, we 
are adjusting the outlier threshold amount to maintain total estimated 
outlier payments equal to 2.0 percent of total payments in FY 2027, 
which results in no change in aggregate IPF PPS payments.
    In column 4, we present the effects of the budget-neutral update to 
the IPF wage index, the labor-related share, and the final COLA 
changes. In addition, this column includes the application of the 5-
percent cap on any decrease to a provider's wage index from its wage 
index in the prior year as finalized in the FY 2023 IPF PPS final rule 
(87 FR 46856 through 46859). The change in this column represents the 
effect of using the concurrent hospital wage data as discussed in 
section IV.D.1.c. of this final rule. That is, the impact represented 
in this column reflects the update from the FY 2026 IPF wage index to 
the FY 2027 IPF wage index, which includes basing the FY 2027 IPF wage 
index on the FY 2027 pre-floor, pre-reclassified IPPS hospital wage 
index data, applying a 5-percent cap on any decrease to a provider's 
wage index from its wage index in the prior year, and updating the 
labor-related share from 79.0 percent in FY 2026 to 78.9 percent in FY 
2027. We note that there is no projected change in aggregate payments 
to IPFs, as indicated in the first row of column 4; however, there 
would be distributional effects among different categories of IPFs. For 
example, we estimate the largest increase in payments to be 1.6 percent 
for non-profit IPF hospitals located in rural areas, and the largest 
decrease in payments to be 1.1 percent for IPF hospitals with 25-49 
beds.

[[Page 48581]]

    Overall, IPFs are estimated to experience a net increase in 
payments of 2.3 percent as a result of the updates in this final rule. 
IPF payments are therefore estimated to increase by 2.2 percent in 
urban areas and 2.7 percent in rural areas. The largest payment 
increase is estimated at 4.0 percent for non-profit IPF hospitals 
located in rural areas.
4. Effect on Beneficiaries
    Under the FY 2027 IPF PPS, IPFs will continue to receive payment 
based on the average resources consumed by patients for each day. Our 
longstanding payment methodology reflects the differences in patient 
resource use and costs among IPFs, as required under section 124 of the 
BBRA. We expect that updating IPF PPS rates in this rule will improve 
or maintain beneficiary access to high-quality care by ensuring that 
payment rates reflect the best available data on the resources involved 
in inpatient psychiatric care and the costs of these resources. We 
continue to expect that paying prospectively for IPF services under the 
FY 2027 IPF PPS will enhance the efficiency of the Medicare program.
5. Effects of the Updates to the IPF Quality Reporting Program
    In section V.B. of this final rule, we finalized the removal of two 
measures from the IPF Quality Reporting Program beginning with the FY 
2028 payment determination: Alcohol Use Brief Intervention Provided or 
Offered and Alcohol Use Brief Intervention (SUB-2/2a) and Tobacco Use 
Treatment Provided or Offered at Discharge (TOB-3/3a). Because these 
measures require IPFs to abstract data from a sample of patients' 
medical records, we estimate the removal of these measures to reduce 
476,238 hours of annual information collection burden on IPFs, valued 
at $26,221,664, in CY 2027.
    In section V.C. of this final rule, we finalized the implementation 
of the IPF Patient Assessment Instrument (IPF-PAI), required by section 
4125(b)(1) of the Consolidated Appropriations Act of 2023, beginning 
with voluntary reporting starting October 1, 2027--that is, Quarter 4 
of CY 2027--and mandatory reporting beginning July 1, 2028--that is, 
Quarter 3 of CY 2028. Quarters 3 and 4 of CY 2028 will impact the FY 
2030 payment determination. IPFs will have the option of two methods 
for submission of IPF-PAI data to CMS: web application and FHIR[supreg] 
API. As IPFs have not yet used FHIR[supreg] for program data 
submission, we acknowledge that technological, financial, and staffing 
barriers may present challenges to adoption and use in some facilities. 
We also recognize that IPFs and the health IT vendors that support IPFs 
will require time to develop and implement data collection and 
submission tools for the proposed IPF-PAI. Because each IPF and health 
IT vendor is unique and we lack sufficient insight into the individual 
workflows and decisions for each, the extent of these costs is 
difficult to quantify. However, in Section VII.C.3. of this final rule, 
we estimate the adoption of the IPF-PAI to increase collection of 
information burden by 419,778 hours annually, valued at $27,302,361, 
when fully implemented.
    In accordance with section 1886(s)(4)(A) of the Act, we will apply 
a 2-percentage point reduction to the FY 2027 market basket update for 
IPFs that have failed to comply with the IPF Quality Reporting Program 
requirements for the FY 2027 payment determination, including reporting 
on the mandatory measures. Historically, approximately 70 IPFs, or 
about 5 percent of IPFs that participate in the IPF Quality Reporting 
Program do not receive the full annual percentage increase in any 
fiscal year due to the failure to meet all requirements of the program. 
We anticipate that the number of IPFs not receiving the full annual 
percentage increase will be approximately the same as in past years 
based on review of previous performance. We intend to closely monitor 
the effects of the IPF Quality Reporting Program on IPFs and help 
facilitate successful reporting outcomes through ongoing education, 
national trainings, and a technical help desk.
6. Regulatory Review Costs
    If regulations impose administrative costs on private entities, 
such as the time needed to read and interpret this final rule, we 
should estimate the cost associated with the regulatory review. Due to 
the uncertainty involved with accurately quantifying the number of 
entities that will review this final rule, we assume that the total 
number of unique commenters on the most recent IPF PPS proposed rule 
will be the number of reviewers of this final rule. For this FY 2027 
IPF PPS final rule, the most recent IPF proposed rule was the FY 2027 
IPF PPS proposed rule, and we received 176 unique comments on the 
proposed rule. We acknowledge that this assumption may understate or 
overstate the costs of reviewing this rule. It is possible that not all 
commenters reviewed the FY 2027 IPF proposed rule in detail, and it is 
also possible that some reviewers chose not to comment on the proposed 
rule. For these reasons we thought that the number of commenters would 
be a fair estimate of the number of reviewers of this rule. We welcomed 
public comments on the approach in estimating the number of entities 
that would review the proposed rule. We did not receive any public 
comments specific to our solicitation.
    We also recognize that different types of entities are in many 
cases affected by mutually exclusive sections of the proposed rule, and 
therefore for the purposes of our estimate, we assume that each 
reviewer reads approximately 50 percent of the rule. We sought public 
comments on this assumption. We did not receive any public comments 
specific to our solicitation.
    Using the May, 2025 mean (average) wage information from the Bureau 
of Labor Statistics (BLS) for medical and health service managers (Code 
11-9111), we estimate that the cost of reviewing this final rule is 
$135.54 per hour, including overhead and fringe benefits (https://data.bls.gov/oes/#/area/0000000/2025). Assuming an average reading 
speed of 250 words per minute, we estimate that it would take 
approximately 2.24 hours for the staff to review half of this final 
rule which contains a total of approximately 67,300 words. For each 
entity that reviews the rule, the estimated cost is $303.61 (2.24 hours 
x $135.54). Therefore, we estimate that the total cost of reviewing 
this regulation is $53,435.29 ($303.61 x 176 reviewers).

D. Alternatives Considered

    The statute gives the Secretary discretion in establishing an 
update methodology to the IPF PPS. We continued to believe it is 
appropriate to routinely update the IPF PPS so that it reflects the 
best available data about differences in patient resource use and costs 
among IPFs, as required by the statute. Therefore, we are updating to 
the IPF PPS using the methodology published in the RY 2005 IPF PPS 
final rule (our ``standard methodology''), with the pre-floor, pre-
reclassified IPPS hospital wage index as its basis. Additionally, we 
apply a 5-percent cap on any decrease to a provider's wage index from 
its wage index in the prior year.
    As discussed in section IV.E.1. of this final rule, we considered 
multiple alternative policy approaches, including maintaining the 
current methodology, adjusting the fixed-dollar loss threshold alone, 
implementing targeted audits, and establishing alternative cap levels. 
We considered implementing the proposed changes to the outlier cap 
policy effective for FY 2027, however,

[[Page 48582]]

we intend to conduct additional analysis of the potential drivers of 
cost. Based on the available claims and cost report data, CMS concludes 
that the finalized policy most effectively advances the statutory 
objective of appropriately accounting for differences in patient 
resource use while preserving access to care and maintaining payment 
accuracy.
    Lastly, as discussed in section IV.D.4. of this final rule, we are 
adjusting non-labor related costs for IPFs located in Alaska and Hawaii 
using the Overseas Cost-of-Living Allowance (OCOLA) data published by 
the DOW for FY 2027 consistent with payments for other hospitals 
located in Alaska and Hawaii. We considered, but did not propose, 
updating the COLA factors for IPFs based on the results of our existing 
methodology.

E. Accounting Statement

    Consistent with OMB Circular A-4 (available at https://www.whitehouse.gov/wp-content/uploads/2025/08/CircularA-4.pdf), in 
Table 17, we have prepared an accounting statement showing the 
classification of the expenditures associated with the updates to the 
IPF wage index and payment rates in this final rule. Table 17 provides 
our best estimate of the increase in Medicare payments under the IPF 
PPS as a result of the changes presented in this final rule and based 
on 1,336 IPFs that had data available in the PSF and claims in our FY 
2025 MedPAR claims dataset. Lastly, Table 17 also includes our best 
estimate of the costs of reviewing and understanding this final rule.

F. Regulatory Flexibility Act (RFA)

    The RFA requires agencies to analyze options for regulatory relief 
of small entities if a rule has a significant impact on a substantial 
number of small entities. For purposes of the RFA, small entities 
include small businesses, nonprofit organizations, and small 
governmental jurisdictions.
1. The Need for, Objectives of, and Legal Basis for the Rule
    Section 124 of the Medicare, Medicaid, and State Children's Health 
Insurance Program Balanced Budget Refinement Act of 1999 (BBRA) (Pub. 
L. 106-113) required the establishment and implementation of an IPF PPS 
in a budget neutral manner. Specifically, section 124 of the BBRA 
mandated that the Secretary of Health and Human Services (the 
Secretary) develop a per diem prospective payment system (PPS) for 
inpatient hospital services furnished in psychiatric hospitals and 
excluded psychiatric units including an adequate patient classification 
system that reflects the differences in patient resource use and costs 
among psychiatric hospitals and excluded psychiatric units.
    Sections 3401(f) and 10322 of the Patient Protection and Affordable 
Care Act (Pub. L. 111-148) as amended by section 10319(e) of that Act 
and by section 1105(d) of the Health Care and Education Reconciliation 
Act of 2010 (Pub. L. 111-152) (``the Affordable Care Act'') added 
subsection (s) to section 1886 of the Act.
    Section 1886(s)(1) of the Act titled ``Reference to Establishment 
and Implementation of System,'' refers to section 124 of the BBRA, 
which relates to the establishment of the IPF PPS.
2. Identify the Impacted Small Entities
    According to the SBA's website at http://www.sba.gov/content/small-business-size-standards, IPFs fall into the North American Industrial 
Classification System (NAICS) code 622210, Psychiatric and Substance 
Abuse hospitals. The SBA defines small Psychiatric and Substance Abuse 
hospitals as businesses having less than $47 million in total annual 
revenue. SUSB data shows there are 190 firms below this threshold.

[[Page 48583]]

[GRAPHIC] [TIFF OMITTED] TR31JY26.042

    According to Table 18, 190 psychiatric and substance abuse 
hospitals, at the firm level, can be considered small according to the 
SBA. As we stated earlier, the SBA defines small Psychiatric and 
Substance Abuse hospitals (firms) as businesses having less than $47 
million in total annual revenue. According to the U.S. Census, a firm 
is a legal entity or parent company that owns and operates the 
business, or hospital, in this case. Therefore, Table 17 only reflects 
data at the firm level and not at the establishment level, where 
multiple establishments could be owned by a firm.
3. Define ``Significant Impact'' and ``Substantial Number'' Thresholds
    As its measure of significant economic impact on small entities, 
HHS uses a change in revenue of more than 3 to 5 percent. The agency 
considers the rule to have a significant impact on a substantial number 
of small businesses when more than 5 percent of impacted small entities 
meet the significant economic impact threshold defined above.

[[Page 48584]]

[GRAPHIC] [TIFF OMITTED] TR31JY26.043

4. The Estimated Impact to Small Businesses
    As discussed in sections VII.C.5 and VII.C.6, costs imposed by this 
final rule include the regulatory review costs which we estimate at 
$303.61 per IPF (there were 176 IPFs that reviewed the rule); and the 
implementation of the Inpatient Psychiatric Facilities-Patient 
Assessment Instrument (IPF-PAI), which we estimate at $17,456.75 per 
IPF ($27,302,361.00/1,564) (based on the estimate of 1,564 IPFs 
described in section VI.B. of this final rule). However, as discussed 
in sections V.B.1. and V.B.2. of this final rule, the removal of the 
Alcohol Use Brief Intervention Provided or Offered (SUB-2) and subset 
Alcohol Use Brief Intervention (SUB-2a) measure and the Tobacco Use 
Treatment Provided or Offered at Discharge (TOB-3) and subset Tobacco 
Use Treatment at Discharge (TOB-3a) measure from the IPF Quality 
Reporting Program would result in an estimated decrease in cost of 
$8,382.88 per IPF ($13,110,832.00/1,564) for each measure removal, 
totaling a decrease in cost of $16,765.77 per IPF ($8,382.88 * 2). As a 
result, there are increased costs of $994.59 per IPF (($303.61 + 
$17,456.75) - $16,765.77) imposed as a result of this final rule.
    As shown in Table 19, 100 percent of these small Psychiatric and 
Substance Abuse hospitals will incur costs as a result of this final 
rule.
5. Does the impact on small entities meet the two-part threshold?
    According to Table 19, this final rule will have almost no impact 
(0.01 percent impact) on small Psychiatric and Substance Abuse 
hospitals. Costs for small Psychiatric and Substance Abuse hospitals 
are estimated to increase by $994.59 per IPF ($690.98 as a result of 
the IPF Quality Reporting Program requirements ($17,456.75 - 
$16,765.77), and $303.61 as a result of the regulatory review costs.) 
As its measure of significant economic impact on a substantial number 
of small entities, HHS uses a change in revenue of more than 3 to 5 
percent. Moreover, given that the annual revenue for the 5th percentile 
firm is $462,500 and 3 percent of this revenue gives a significant 
impact threshold of $13,875, then any cost estimates smaller than this 
estimate will not have a significant impact on a substantial number of 
small entities.
    Assuming the firm size distribution provided in Table 19, we expect 
the annualized costs estimated as a result of this final rule to fall 
below this significant impact threshold. We also believe this estimate 
to be an upper-

[[Page 48585]]

bound since the cost increase from the implementation of the IPF-PAI 
will scale based on the number of patients treated. As such, we 
anticipate that small Psychiatric and Substance Abuse hospitals will 
likely have a lower burden due to having fewer patient stays; and 
therefore, fewer IPF-PAI assessments to be completed on an annual 
basis. We believe that the threshold for significant economic impact on 
a substantial number of small entities will not be reached by the 
requirements in this final rule.
6. Steps Taken To Minimize Impact on Small Entities
    Section 603(c) mandates that agencies shall contain a description 
of any significant alternatives to the final rule which accomplish the 
stated objectives of applicable statutes and which minimize any 
significant economic impact of the final rule on small entities. As 
discussed in section V.C. of this final rule, we are implementing the 
IPF-PAI in the IPF Quality Reporting Program to comply with section 
1886(s)(4)(E) of the Act, which requires each IPF participating in the 
IPF Quality Reporting Program to collect and submit to the Secretary 
certain standardized patient assessment data, using a standardized 
patient assessment instrument (PAI) implemented by the Secretary. We 
are finalizing several modifications to the IPF-PAI timelines for 
mandatory reporting and compliance thresholds to reduce burden. The 
revised burden estimate is discussed in section VII.C. of this final 
rule. At this time, we have not identified any viable alternative that 
would accomplish the stated objectives of section 1886(s)(4)(E) of the 
Act while further reducing the economic impact of the final rule on 
small entities.
    In addition, section 1102(b) of the Act requires us to prepare a 
regulatory impact analysis if a rule may have a significant impact on 
the operations of a substantial number of small rural hospitals. This 
analysis must conform to the provisions of section 604 of the RFA. For 
the purposes of section 1102(b) of the Act, we define a small rural 
hospital as a hospital that is located outside of a metropolitan 
statistical area and has fewer than 100 beds.
    As discussed in section VI.C.2. of this final rule, the rates and 
policies set forth in this final rule will not have an adverse impact 
on the rural hospitals based on the data of the 167 rural excluded 
psychiatric units and 64 rural psychiatric hospitals in our database of 
1,336 IPFs for which data were available. Therefore, the Secretary has 
certified that this final rule will not have a significant impact on 
the operations of a substantial number of small rural hospitals.

G. Unfunded Mandate Reform Act (UMRA)

    Section 202 of the Unfunded Mandates Reform Act of 1995 (UMRA) also 
requires that agencies assess anticipated costs and benefits before 
issuing any rule whose mandates require spending in any 1 year of $100 
million in 1995 dollars, updated annually for inflation. In 2026, that 
threshold is approximately $193 million. This final rule does not 
mandate any requirements for State, local, or tribal governments, or 
for the private sector. This final rule will not impose a mandate that 
will result in the expenditure by State, local, and tribal governments, 
in the aggregate, or by the private sector, of more than $193 million 
in 1 year.

H. Federalism

    Executive Order 13132 establishes certain requirements that an 
agency must meet when it promulgates a proposed rule (and subsequent 
final rule) that imposes substantial direct requirement costs on State 
and local governments, preempts State law, or otherwise has Federalism 
implications. This final rule does not impose substantial direct costs 
on state or local governments or preempt State law.

I. E.O. 14192, ``Unleashing Prosperity Through Deregulation''

    Executive Order 14192, entitled ``Unleashing Prosperity Through 
Deregulation'' was issued on January 31, 2025, and requires that ``any 
new incremental costs associated with new regulations shall, to the 
extent permitted by law, be offset by the elimination of existing costs 
associated with at least 10 prior regulations.'' This final rule is 
expected to be considered an Executive Order 14192 regulatory action. 
We estimate that this final rule will generate $2.59 million in 
annualized cost at a 7 percent discount rate, over a perpetual time 
horizon.
    This final regulation is subject to the Congressional Review Act 
provisions of the Small Business Regulatory Enforcement Fairness Act of 
1996 (5 U.S.C. 801 et seq.) and has been transmitted to the Congress 
and the Comptroller General for review.
    Mehmet Oz, Administrator of the Centers for Medicare & Medicaid 
Services, approved this document.

a. Revising paragraphs (a) and (d); and
0
b. Adding paragraph (h).
    The revisions and addition read as follows:


Sec.  412.433  >Procedural requirements under the IPFQR Program.

    (a) Statutory authority. Section 1886(s)(4) of the Act requires the 
Secretary to implement a quality reporting program for inpatient 
psychiatric hospitals and psychiatric units. Under section 1886(s)(4) 
of the Act, for an IPF paid under the IPF PPS that fails to submit data 
required for the quality measures and standardized patient assessment 
data selected by the Secretary in a form and manner and at a time 
specified by the Secretary, we reduce the otherwise applicable annual 
update to the standard Federal rate by 2.0 percentage points with 
respect to the applicable fiscal year.
* * * * *
    (d) Submission of IPFQR Program data. In general, except as 
provided in paragraph (f) of this section, IPFs that participate in the 
IPFQR Program must submit to CMS data on measures selected under 
section 1886(s)(4)(D) of

[[Page 48586]]

the Act and specified non-measure data, including standardized patient 
assessment data under section 1886(4)(E) of the Act, in a form and 
manner, and at a time specified by CMS. With respect to data collection 
for the standardized patient assessment instrument, mandatory data 
collection will begin with the third quarter 2028 reporting period. 
Data submitted prior to this will not affect payment.
* * * * *
    ((h) Compliance threshold for the IPF Patient Assessment Instrument 
(IPF-PAI). IPFs must meet or exceed a compliance threshold for 
standardized patient assessment data collected using the IPF-PAI to 
avoid receiving a 2 percentage point reduction to their annual payment 
update for a given fiscal year as set forth in paragraph (a) of this 
section. We define the compliance threshold as the required percent of 
assessments IPFs submit through the CMS designated data submission 
system that are 100 percent complete--that is, that contain all 
required IPF-PAI standardized patient assessment items. For the FY 2030 
and FY 2031 IPF Quality Reporting Program payment updates, the 
compliance threshold is set as at least 50 percent. For the FY 2032 and 
all subsequent payment updates, the compliance threshold is set at 70 
percent.
