AGENCY: Centers for Medicare & Medicaid Services (CMS) and Office of 
the National Coordinator for Health Information Technology (ONC), 
Department of Health and Human Services (HHS).

ACTION: Proposed rule.

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

SUMMARY: These proposals are intended to improve the electronic 
exchange of health care data and streamline processes related to prior 
authorization by increasing the interoperability of systems used across 
the health care industry. We are proposing new requirements for 
Medicare Advantage (MA) organizations, state Medicaid fee-for-service 
(FFS) programs, state Children's Health Insurance Program (CHIP) FFS 
programs, Medicaid managed care plans, CHIP managed care entities, and 
Qualified Health Plan (QHP) issuers on the Federally-facilitated 
Exchanges (FFEs), including issuers that offer small group market QHPs 
on the Federally-facilitated Small Business Health Options Program (FF-
SHOP) Exchanges (hereinafter referred to as ``small group market QHP 
issuers on the FF-SHOPs'') (collectively ``impacted payers''), to make 
available electronic prior authorization for drugs. We are also 
proposing to extend many existing interoperability requirements for the 
prior authorization of non-drug items and services to include prior 
authorizations for drugs to further reduce patient and provider burden.
    We are also proposing to require impacted payers to report their 
application programming interfaces (API) endpoints and related 
information for the Patient Access, Provider Directory, Provider 
Access, Payer-to-Payer, and Prior Authorization APIs to CMS. To help 
assess the impact of our policies, we are proposing to collect API 
usage metrics. In addition, we are proposing to apply the existing 
interoperability requirements to small group market QHP issuers on the 
FF-SHOPs as impacted payers. To improve impacted payers' ability to 
exchange health information while continuing CMS's drive toward 
interoperability, we are proposing to require certain Health Level 
Seven (HL7[supreg]) Fast Healthcare Interoperability Resources 
(FHIR[supreg]) implementation guides (IGs) that are currently 
recommended. In addition, HHS is proposing to adopt the HL7 FHIR base 
standard and certain associated specifications and IGs as the Health 
Insurance Portability and Accountability Act of 1996 (hereinafter 
referred to as ``HIPAA'') (Pub. L. 104-191, enacted Aug. 21, 1996) 
standards for dental, professional, and institutional ``referral 
certification and authorization'' transactions and ``eligibility for a 
health plan'' transactions associated with prior authorization. We are 
proposing to add a definition for ``failure to report,'' which would 
allow CMS to impose a civil monetary penalty (CMP) on applicable 
manufacturers or applicable group purchasing organizations (GPOs) if 
those entities fail to grant CMS timely access to documents for the 
purposes of an audit. Finally, ONC is using this rulemaking to propose 
to adopt updated versions of certain health information technology 
(health IT) standards and specifications for HHS use, such as CMS's 
interoperability requirements, to support a more robust health IT 
infrastructure.

I. Background, Summary of Proposals, Terms, and Severability

A. Purpose and Background

    The ``Medicare and Medicaid Programs; Patient Protection and 
Affordable Care Act; Interoperability and Patient Access for MA 
Organizations and Medicaid Managed Care Plans, State Medicaid Agencies, 
CHIP Agencies and CHIP Managed Care Entities, Issuers of Qualified 
Health Plans on the Federally-Facilitated Exchanges, and Health Care 
Providers'' final rule (85 FR 25510) (hereinafter referred to as the 
``2020 CMS Interoperability and Patient Access final rule'') appeared 
in the Federal Register on May 1, 2020. That rule was the first phase 
of CMS's interoperability rulemaking and focused on giving patients 
access to their health data maintained by their payer through a Patient 
Access API. In that rule, we required MA organizations, state Medicaid 
and CHIP FFS programs, Medicaid managed care plans, CHIP managed care 
entities, and issuers that offer individual market QHPs on the FFEs 
(hereinafter referred to as ``individual market QHP issuers on the 
FFEs'') to implement a Patient Access API that allows patients, through 
health apps with the necessary functionality, to easily access their 
claims and encounter information, provider remittances, patient cost-
sharing information, and clinical data, including laboratory results, 
maintained by the impacted payer.\1\
---------------------------------------------------------------------------

    \1\ See 42 CFR 422.119(b) for MA organizations, 42 CFR 431.60(b) 
for state Medicaid FFS programs, 42 CFR 457.730(b) for state CHIP 
FFS programs, cross reference to 42 CFR 431.60 in 42 CFR 
438.242(b)(5) for Medicaid managed care plans, cross reference to 42 
CFR 438.242 in 42 CFR 457.1233(d) for CHIP managed care entities, 
and 45 CFR 156.221(b) for individual market QHP issuers on the FFEs.

Affordable Care Act; Advancing Interoperability and Improving Prior 
Authorization Processes for Medicare Advantage Organizations, Medicaid 
Managed Care Plans, State Medicaid Agencies, Children's Health 
Insurance Program (CHIP) Agencies and CHIP Managed Care Entities, 
Issuers of Qualified Health Plans on the Federally-Facilitated 
Exchanges, Merit-Based Incentive Payment System (MIPS) Eligible 
Clinicians, and Eligible Hospitals and Critical Access Hospitals (CAHs) 
in the Medicare Promoting Interoperability Program'' final rule (89 FR 
8758) (hereinafter referred to as the ``2024 CMS Interoperability and 
Prior Authorization final rule'') appeared in the Federal Register on 
February 8, 2024. In that rule, we finalized requirements for impacted 
payers to improve the electronic exchange of health care information, 
not just with patients, but also with providers and other payers. We 
also finalized requirements for impacted payers to implement and 
maintain a Prior Authorization API that supports electronic prior 
authorization between providers and payers.\2\ We also finalized 
general process requirements for prior authorization, such as requiring 
MA organizations, state Medicaid and CHIP FFS programs, Medicaid 
managed care plans, and CHIP managed care entities to respond to prior 
authorization requests for non-drug items and services within certain 
timeframes.
---------------------------------------------------------------------------

    \2\ See 42 CFR 422.122(b) for MA organizations, 42 CFR 431.80(b) 
for state Medicaid FFS programs, 42 CFR 457.732(b) for state CHIP 
FFS programs, through cross reference to 42 CFR 431.80(b) in 42 CFR 
438.242(b)(7) for Medicaid managed care plans, through cross 
reference to 42 CFR 438.242 in 42 CFR 457.1233(d) for CHIP managed 
care entities, and 45 CFR 156.223(b) for individual market QHP 
issuers on the FFEs.
---------------------------------------------------------------------------

    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we did not propose or finalize requirements that apply to drugs 
of any type because, as we discussed in the proposed and final rules, 
the processes and electronic standards for prior authorization of drugs 
differ from the non-drug items and services included in our final 
policies. We also acknowledged that there are existing laws and 
regulations around the prior authorization of drugs that may apply to 
impacted payers (such as the existing electronic prescribing 
requirements for covered Part D drugs in 42 CFR 423.160) (87 FR 76240 
and 76241, and 89 FR 8762). However, we received many public comments 
in response to the ``Medicare and Medicaid Programs; Patient Protection 
and Affordable Care Act; Advancing Interoperability and Improving Prior 
Authorization Processes for Medicare Advantage Organizations, Medicaid 
Managed Care Plans, State Medicaid Agencies, Children's Health 
Insurance Program (CHIP) Agencies and CHIP Managed Care Entities, 
Issuers of Qualified Health Plans on the Federally-Facilitated 
Exchanges, Merit-Based Incentive Payment System (MIPS) Eligible 
Clinicians, and Eligible Hospitals and Critical Access Hospitals in the 
Medicare Promoting Interoperability Program'' proposed rule (87 FR 
76238) (hereinafter referred to as the ``2022 CMS Interoperability and 
Prior Authorization proposed rule''), which appeared in the Federal 
Register on December 13, 2022, as well as additional feedback from 
providers, payers, and standards developing organizations (SDOs), 
indicating that while some prior authorization processes and standards 
for drugs currently exist, the health care industry would benefit from 
consistent electronic prior authorization requirements to promote 
patients' timely access to drugs and alleviate burden for providers and 
payers. Commenters emphasized the impact that prior authorization for 
drugs has on patients and providers and urged CMS to implement similar 
requirements for drugs as were proposed for non-drug items and 
services. In addition, commenters explained that the Prior 
Authorization API can facilitate electronic prior authorization for 
drugs covered under a medical benefit, so the same standards and 
requirements could be used for that category of drugs. Commenters also 
pointed out that requirements already existed for Medicare Part D 
sponsors to support (and prescribers to use) a standard adopted by the 
Secretary for the prior authorization of covered Part D drugs, the 
National Council for Prescription Drug Programs (NCPDP) SCRIPT Standard 
Implementation Guide (NCPDP SCRIPT standard). Those

[[Page 19892]]

commenters suggested modeling requirements for the other types of 
impacted payers on the existing Part D requirements in 42 CFR 423.160, 
as established in the ``Medicare Program; Secure Electronic Prior 
Authorization for Medicare Part D'' final rule (85 FR 86824) 
(hereinafter referred to as the ``2020 Medicare Part D ePA final 
rule''), which appeared in the Federal Register on December 31, 2020.
    The 2024 CMS Interoperability and Prior Authorization final rule 
also established, improved, or shortened prior authorization timeframes 
for impacted payers other than QHP issuers on the FFEs (MA 
organizations, state Medicaid and CHIP FFS programs, Medicaid managed 
care plans, and CHIP managed care entities) to respond to prior 
authorization requests for non-drug items and services. Specifically, 
we finalized timeframes of 7 calendar days for standard requests and 72 
hours for expedited requests, with the possibility of an extension of 
up to 14 days in certain circumstances (89 FR 8878). For Medicaid and 
CHIP, state law may establish a shorter timeframe.\3\ Some of the 
payers affected by those requirements had existing timeframes for prior 
authorization decisions, notices, and appeals that differed, so we 
aligned the prior authorization decision timeframes across impacted 
payers, except for QHP issuers on the FFEs (89 FR 8878). As discussed 
in the 2022 CMS Interoperability and Prior Authorization proposed rule 
and the 2024 CMS Interoperability and Prior Authorization final rule, 
we did not propose prior authorization decision timeframes for QHP 
issuers on the FFEs, in part because existing regulations in 45 CFR 
147.136 already establish internal claims and appeals processes, 
external review processes, and pre-service claims (prior authorization) 
requirements for all non-grandfathered group and individual market 
plans or coverage (87 FR 76297 and 89 FR 8879). Specifically, 45 CFR 
147.136(b)(3) specifies that individual market QHP issuers on the FFEs 
are generally subject to requirements of the Employee Retirement Income 
Security Act of 1974 (hereinafter referred to as ``ERISA'') (Pub. L. 
93-406, enacted September 2, 1974) and internal claims and appeals 
procedures applicable to group health plans under 29 CFR 2560.503-1 as 
if the issuer were a group health plan. Thus, QHP issuers on the FFEs 
are required to provide notification of a plan's benefit determination 
for pre-service claims to enrollees within a reasonable period of time 
appropriate to the medical circumstances, but not later than 15 days 
for standard prior authorization decisions, and as soon as possible, 
taking into account the medical exigencies, but not later than 72 hours 
for expedited requests. The latter is a similar timeframe for notices 
to enrollees for expedited authorization decisions as finalized for 
other impacted payers (89 FR 8880).
---------------------------------------------------------------------------

    \3\ See 42 CFR 440.230(e) for state Medicaid FFS programs, 42 
CFR 457.495(d)(2) for state CHIP FFS programs, 42 CFR 438.210(d) for 
Medicaid managed care plans, and 42 CFR 457.1230(d) for CHIP managed 
care entities. State law may not impose a shorter timeline on MA 
organizations in light of the preemption provisions in section 
1856(b)(3) of the Social Security Act (the Act) and 42 CFR 422.402.
---------------------------------------------------------------------------

    At the time, we did not propose to change those timeframes because 
they are aligned with other non-grandfathered group and individual 
market plans. However, we received numerous comments that opposed the 
exclusion of QHP issuers on the FFEs from these policies and urged that 
QHPs offered on the FFEs should be aligned with the requirements for 
other CMS programs. Some expressed concern that not doing so would have 
negative effects on enrollee care, and that enrollees with coverage 
through these plans should be entitled to the same protections as those 
with coverage through the other impacted payers. In addition, we 
received comments that recommended we reconsider the exclusion of drugs 
from our proposals and suggested that CMS finalize the prior 
authorization process and Prior Authorization API requirements in the 
2024 CMS Interoperability and Prior Authorization final rule to cover 
drugs covered under a medical benefit. Commenters further expressed 
that by failing to include drugs in those requirements, CMS was failing 
to address the biggest culprit of delay to timely care and 
administrative burden.

B. Summary of Major Proposals

    We are proposing to require that impacted payers support electronic 
prior authorization for all drugs that require prior authorization. We 
are proposing two separate sets of standards to facilitate electronic 
prior authorization for all drugs, the HL7 FHIR standard (and certain 
FHIR IGs) as one set, and three NCPDP standards (the NCPDP SCRIPT 
standard, NCPDP Formulary & Benefit Standard Implementation Guide 
[NCPDP F&B standard], and the NCPDP Real-Time Prescription Benefit 
Standard Implementation Guide [NCPDP RTPB standard]) as the other set. 
The FHIR standard, including the IGs, and the three NCPDP standards, 
all facilitate electronic prior authorization for drugs; which 
standards set is applicable depends on whether the drug is covered 
under the payer's medical benefit or its pharmacy benefit. We are 
proposing to require impacted payers to expand their Prior 
Authorization API, finalized in the 2024 CMS Interoperability and Prior 
Authorization final rule (89 FR 8758), to incorporate drugs covered 
under a medical benefit. We are also proposing to require impacted 
payers (other than MA organizations for whom requirements already 
exist) to support the proposed NCPDP standards for the electronic prior 
authorization of drugs covered under a pharmacy benefit.
    As proposed in this proposed rule, the Prior Authorization API 
comprises the HL7 FHIR Da Vinci Coverage Requirements Discovery (CRD) 
IG, the HL7 FHIR Da Vinci Documentation Templates and Rules (DTR) IG, 
and the HL7 FHIR Da Vinci Prior Authorization Support (PAS) IG, and can 
be used to support drugs under a medical benefit, but should not be 
used for the prior authorization of drugs covered under a pharmacy 
benefit. Specifically, the PAS IG states that the IG ``SHOULD NOT be 
used for any medication that is covered under a pharmacy benefit where 
prior authorization is provided by another electronic exchange process 
(for example, NCPDP SCRIPT).'' \4\

    Conversely, the NCPDP SCRIPT standard include instructions that it 
is to be used for ``products covered by a patient's pharmacy benefit.'' 
The NCPDP F&B and NCPDP RTPB standards complement the NCPDP SCRIPT 
standard and apply to the same category of drugs. Payers can use the 
NCPDP F&B standard to make available formulary and benefit information, 
including prior authorization requirements, at the health plan level. 
The NCPDP RTPB standard enables real-time exchange at the point-of-
prescribing of patient-specific eligibility, coverage, and estimated 
cost-sharing information for drugs covered

[[Page 19893]]

under a pharmacy benefit. Therefore, these sets of FHIR and NCPDP 
standards are mutually exclusive and, when used in conjunction, 
encompass the full scope of drugs that are covered by any particular 
payer. We propose that impacted payers be required to support 
electronic prior authorization for all drugs through the Prior 
Authorization API and NCPDP standards beginning on October 1, 2027.
    Our proposals regarding the prior authorization of drugs are 
similar to the provisions finalized for non-drug items and services in 
the 2024 CMS Interoperability and Prior Authorization final rule (89 FR 
8897) but with special consideration to existing policies, operational 
processes, and standards for the electronic prior authorizations of 
drugs. The proposals would require impacted payers to support 
electronic prior authorization for all drugs, which should improve the 
process for impacted payers' patients and providers. In section II.A. 
of this proposed rule, we describe each of these standards and how they 
would be used. In section II.B. of this proposed rule, we describe our 
proposals as they apply to each category of impacted payer, including 
program specifics as to distinction of drugs covered under medical 
benefits versus drugs covered under pharmacy benefits.
    For the proposed requirement to incorporate drugs covered under a 
medical benefit into the Prior Authorization API, we are proposing an 
October 1, 2027 compliance date. As discussed in section II.B.3. of 
this proposed rule, incorporating drugs into Prior Authorization APIs 
means that, using the proposed standards, information is available 
through the API as to whether prior authorization is required for drugs 
covered under a medical benefit, the coverage and documentation 
requirements for prior authorization are available, and that the API 
can transmit prior authorization requests and decisions between 
providers and the payer.
    Medicare Part D sponsors (including MA organizations that offer a 
Medicare Advantage Prescription Drug [MA-PD] plan) are already 
required, in 42 CFR 423.160(b)(1), to use an unexpired version of the 
NCPDP SCRIPT standard adopted by the Secretary in 45 CFR 170.205(b) as 
part of their electronic prescription drug programs. Prescribers and 
dispensers are also required to use an adopted version of the NCPDP 
SCRIPT standard when electronically transmitting prescriptions and 
prescription-related information for covered Part D drugs for Part D-
eligible individuals. Similarly, beginning January 1, 2027, Part D 
sponsors are required, in 42 CFR 423.160(b)(3) and (b)(5), to implement 
for uses described in those paragraphs unexpired versions of the NCPDP 
F&B and RTPB standards adopted by the Secretary in 45 CFR 170.205(u) 
and 45 CFR 170.205(c), respectively.
    We propose that state Medicaid and CHIP FFS programs, Medicaid 
managed care plans, CHIP managed care entities, and QHP issuers on the 
FFEs, including small group market QHP issuers on the FF-SHOPs, 
similarly could use any unexpired version of the NCPDP standards 
adopted by the Secretary in 45 CFR 170.205(b), (c), and (u) to support 
electronic prior authorization of drugs covered under a pharmacy 
benefit. We are proposing an October 1, 2027 compliance date to support 
the proposed NCPDP standards to facilitate electronic prior 
authorization of drugs covered under a pharmacy benefit.
    Consistent with section 3004(b)(3) of the PHSA, the Secretary 
adopts standards for HHS use, including those adopted in 45 CFR 
170.215. We are proposing to require impacted payers to implement and 
maintain their required FHIR APIs in conformance with certain 
applicable standards adopted in 45 CFR 170.215, without specifying 
versions of each required standard, which would allow impacted payers 
to use unexpired versions of the required standards, as the Secretary 
adopts updated versions in 45 CFR 170.215. Where more than one 
unexpired version of a standard is adopted in 45 CFR 170.215, impacted 
payers would be able to use any of the unexpired standards, allowing 
for transition periods as updated versions are adopted by the Secretary 
and older versions expire. To support interoperability, these proposals 
require impacted payers to implement and maintain API technology 
conformant with certain IGs that were recommended in the 2024 CMS 
Interoperability and Prior Authorization final rule, as applicable to 
each interoperability API (89 FR 8945). We are proposing an October 1, 
2027 compliance date to implement the proposed standards. We are also 
recommending additional IGs for some of the APIs that could be used to 
support certain use cases.
    We are proposing to replace the policy finalized in the 2024 CMS 
Interoperability and Prior Authorization final rule that allows states 
with small FFS populations to request an exemption from CMS for the 
non-drug items and services Prior Authorization API requirements with a 
policy that would allow all state Medicaid and CHIP FFS programs to 
request extensions to the compliance date for that requirement. We are 
proposing that those extensions would only be available until the 
compliance date for the HIPAA Administrative Simplification proposals 
in this rule, if the proposals are finalized. In addition, we are 
proposing a process for state Medicaid and CHIP FFS programs to request 
from CMS extensions to allow additional time to meet the proposed 
requirement to incorporate drugs covered under a medical benefit into 
the Prior Authorization API and the proposed requirement to support the 
NCPDP standards for electronic prior authorization of drugs covered 
under a pharmacy benefit, if they meet certain criteria. We are also 
proposing that QHP issuers on the FFEs be permitted to request an 
exception from the requirement to support electronic prior 
authorization of drugs covered under a pharmacy benefit through the 
proposed NCPDP standards, as part of the annual QHP certification 
process. Issuers could seek an exception by submitting a narrative 
justification with information specified in 45 CFR 156.223(h), 
including why the QHP issuer on the FFEs cannot reasonably satisfy the 
requirements for the applicable plan year.\5\ Those proposals are 
similar to the exception policies finalized in the 2024 CMS 
Interoperability and Prior Authorization final rule and are discussed 
in section II.B.7. of this proposed rule.\6\
---------------------------------------------------------------------------

    \5\ We note that existing language in 45 CFR 156.223(d)(1)(i) 
would also allow QHP issuers to request an exception to the 
requirement, if finalized, to incorporate electronic prior 
authorization for drugs under a medical benefit into the Prior 
Authorization API.
    \6\ For exceptions, see 45 CFR 156.222(c) and 45 CFR 156.223(d) 
for individual market QHP issuers on the FFEs.

    We are proposing to require state Medicaid and CHIP FFS programs, 
Medicaid managed care plans, CHIP managed care entities, and QHP 
issuers on the FFEs to respond to the provider with a specific reason 
for denying a prior authorization request for any drugs. We are 
proposing an October 1, 2027 compliance date for those impacted payers 
to respond to a provider with a specific reason for denying a prior 
authorization request for any drugs. This proposal builds on the 
requirement finalized in the 2024 CMS Interoperability and Prior 
Authorization final rule that impacted payers must provide a specific 
reason to the provider for denying a prior authorization request for 
non-drug items and services.\7\
---------------------------------------------------------------------------

    \7\ See 42 CFR 422.122(a) for MA organizations and applicable 
integrated plans, 42 CFR 431.80(a) for state Medicaid FFS programs,

for Medicaid managed care plans, 42 CFR 457.732(a) for state CHIP 
FFS programs, through cross reference to 42 CFR 438.242 in 42 CFR 
457.1233(d) for CHIP managed care entities, and 45 CFR 156.223(a) 
for individual market QHP issuers on the FFEs.

    For state Medicaid FFS programs, Medicaid managed care plans, and 
CHIP managed care entities, the timeframes for making decisions on 
prior authorization requests for covered outpatient drugs is 24 
hours.\8\ However, the term ``covered outpatient drugs'' does not apply 
to all drugs that are covered by states for which states receive 
Federal Financial Participation (FFP) from CMS. Therefore, we are 
requesting comment to identify whether there are drugs for which a 
prior authorization timeframe does not currently exist and needs to be 
established. If there are gaps identified in the prior authorization 
decision timeframe requirements for drugs, in order to align patient 
protections and create consistent requirements across the Medicaid and 
CHIP programs, we propose to require state Medicaid FFS programs, 
Medicaid managed care plans, and CHIP managed care entities to provide 
notice of prior authorization decisions for drugs within a timeframe 
that aligns with applicable existing decision timeframe requirements. 
We are proposing an October 1, 2027 compliance date. In addition, we 
are proposing to require state CHIP FFS programs to make decisions on 
prior authorization requests for prescription drugs for which the state 
receives FFP no later than 24 hours after receiving a prior 
authorization request, rather than the current requirements that cover 
both drugs and non-drug items and services. We are proposing an October 
1, 2027 compliance date.
---------------------------------------------------------------------------

    \8\ See section 1927(d)(5)(A) of the Act for state Medicaid FFS 
programs, 42 CFR 438.3(s)(6) for Medicaid managed care plans, and 42 
CFR 457.1230(d) for CHIP managed care entities.
---------------------------------------------------------------------------

    We are proposing to shorten timeframes within which QHP issuers on 
the FFEs, including small group market QHP issuers on the FF-SHOPs, 
must make a decision on prior authorization requests by establishing 
timeframes by which QHP issuers on the FFEs must notify requesting 
providers of their decision. The proposed timeframes generally align 
with the timeframes for other impacted payers that we finalized in the 
2024 CMS Interoperability and Prior Authorization final rule for non-
drug items and services (89 FR 8878) and that we are proposing for 
drugs in this proposed rule. Specifically, we propose to require QHP 
issuers on the FFEs to send notice of their decision to the requesting 
provider for standard prior authorization requests for non-drug items 
and services as expeditiously as the enrollee's health condition 
requires, but no later than 7 calendar days after receiving the 
request. We are not proposing to change the existing 72-hour timeframe 
to notify enrollees about prior authorization decisions on expedited 
requests for non-drug items and services, but are proposing that QHP 
issuers on the FFEs notify the requesting provider of their decision on 
a prior authorization request for non-drug items and services within 
the same timeframe. These proposed timeframes for non-drug items and 
services align with existing timeframes that were finalized in the 2024 
CMS Interoperability and Prior Authorization final rule for MA 
organizations, state Medicaid and CHIP FFS programs, Medicaid managed 
care plans, and CHIP managed care entities (89 FR 8878). We are also 
proposing to require QHP issuers on the FFEs to send notice of their 
decision to the requesting provider for standard prior authorization 
requests for drugs as expeditiously as the enrollee's health condition 
requires, but no later than 72 hours after receiving the request. We 
are further proposing to require QHP issuers on the FFEs to send notice 
of their decision to the requesting provider for expedited prior 
authorization requests for drugs as expeditiously as the enrollee's 
health condition requires, but no later than 24 hours after receiving 
the request. These proposed timeframes generally align with existing 
requirements for Part D sponsors in 42 CFR 423.568(b) and in 42 CFR 
423.572(a). For these proposals, we are proposing an October 1, 2027 
compliance date.
    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we finalized an annual March 31 reporting deadline for all 
impacted payers to report Patient Access API usage metrics to CMS and 
to publicly post prior authorization metrics for non-drug items and 
services from the previous year (89 FR 8784, 8817, and 8855). However, 
we have determined that such deadlines may not align with Medicaid 
managed care plans' and CHIP managed care entities' contract rating 
periods and with the QHP certification process for QHP issuers on the 
FFEs. Therefore, to align the reporting deadlines with the contract 
rating period, we are now proposing to require Medicaid managed care 
plans and CHIP managed care entities to report Patient Access API usage 
metrics from each rating period to states no later than 90 days after 
the end of each rating period and to publicly post the required prior 
authorization metrics for non-drug items and services no later than 90 
days after the end of each rating period. For QHP issuers on the FFEs, 
we are proposing regulatory text to refer to the reporting deadline for 
Patient Access API usage metrics in a manner similar to the reporting 
deadlines for other plan data that CMS collects during the annual QHP 
certification process. Specifically, we propose that following each 
year it offers a QHP on an FFE, a QHP issuer on the FFEs must report 
the specified metrics to CMS as aggregated, de-identified data at the 
issuer level in the form and manner and within the timeframes specified 
by the Secretary. That would allow flexibility for CMS to include API 
usage metrics reporting within specific deadlines set for the QHP 
certification process, which, in practice, is generally the final 
deadline for the QHP certification process that takes place the 
following year.\9\ We are proposing that these changes become effective 
beginning on the effective date of the final rule.
---------------------------------------------------------------------------

    \9\ Information about QHP certification, including deadlines can 
be found at https://www.qhpcertification.cms.gov/QHP/aboutthemarketplace/Timeline.
---------------------------------------------------------------------------

    Building on the requirement finalized in the 2024 CMS 
Interoperability and Prior Authorization final rule that impacted 
payers must report Patient Access API usage metrics to CMS, we are 
proposing to require impacted payers to report similar usage metrics 
about their Provider Access, Payer-to-Payer, and Prior Authorization 
APIs.\10\ Collecting these metrics should help CMS evaluate the impact 
of our policies and plan for future changes, if necessary. We are 
proposing that the metrics would be reported annually by MA 
organizations at the contract level, state Medicaid and CHIP FFS 
programs at the state level, Medicaid managed care plans and CHIP 
managed care entities at the plan and program level, and QHP issuers on 
the FFEs at the issuer level. We are proposing that beginning in 2028, 
MA organizations and state Medicaid and CHIP FFS programs would be 
required to report the previous calendar year's metrics by March 31 of 
each year. We are proposing that Medicaid managed care plans and CHIP 
managed care entities would report their metrics to states from

[[Page 19895]]

each rating period no later than 90 days after the end of each rating 
period. We are proposing that QHP issuers on the FFEs report their API 
usage metrics as aggregated, de-identified data at the issuer level in 
the form and manner and within the timeframes specified by the 
Secretary, as we are proposing to amend the deadline for Patient Access 
API usage metrics. For these proposals, we propose compliance dates 
beginning in 2028.

    \10\ See 42 CFR 422.119(f) for MA organizations, 42 CFR 
431.60(f) for state Medicaid FFS programs, through cross reference

plans, 42 CFR 457.730(f) for CHIP FFS programs, through existing 
cross reference to 42 CFR 438.242 in existing 42 CFR 457.1233(d) for 
CHIP managed care entities, and 45 CFR 156.221(f) for individual 
market QHP issuers on the FFEs.
---------------------------------------------------------------------------

    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we finalized requirements for impacted payers to report on their 
websites certain prior authorization metrics for non-drug items and 
services, including the percentage of prior authorizations that were 
approved, denied, approved after appeal, and approved after the 
timeframe for review was extended (89 FR 8897). In an effort to provide 
more useful and complete information, we are now proposing that 
impacted payers report a numeric count for each of those metrics (in 
addition to the percentages). We are also proposing that impacted 
payers report six new metrics: four new metrics about prior 
authorization denials after an extended timeframe and appeals for non-
drug items and services and two new metrics about prior authorization 
approvals after an extended timeframe and appeals for non-drug items 
and services for expedited prior authorization requests only. The 
proposed metrics complement existing metrics finalized in the 2024 CMS 
Interoperability and Prior Authorization final rule about prior 
authorization approvals after an extended timeframe and appeals for 
non-drug items for standard prior authorization requests. We are 
proposing compliance dates beginning in 2028 for impacted payers to 
report the additional metrics.
    Similarly, we are proposing to require impacted payers to publicly 
post on their websites a set of metrics on prior authorizations for all 
drugs (excluding covered Part D drugs for MA-PD plans). To align with 
the finalized requirements and our new proposals, we are proposing that 
these reports must be posted no later than March 31 following any 
calendar year that the impacted payer offered that type of plan for MA 
organizations, state Medicaid and CHIP FFS programs, and QHP issuers on 
the FFEs, and no later than 90 days after the end of each rating period 
for Medicaid managed care plans and CHIP managed care entities.\11\ We 
are proposing compliance dates beginning in 2028 for impacted payers to 
post these metrics.
---------------------------------------------------------------------------

    \11\ See 42 CFR 422.122(c) for MA organizations and applicable 
integrated plans, 42 CFR 440.230(e)(3) for state Medicaid FFS 
programs, 42 CFR 457.732(c) for state CHIP FFS programs, 42 CFR 
438.210(f) for Medicaid managed care plans, through cross reference 
to 42 CFR 438.210 in 42 CFR 457.1230(d) for CHIP managed care 
entities, and 45 CFR 156.223(c) for individual market QHP issuers on 
the FFEs.
---------------------------------------------------------------------------

    We propose to include small group market QHP issuers on the FF-
SHOPs in the list of impacted payers for all the proposals in this 
proposed rule that apply to individual market QHPs on the FFEs. In 
addition, we are proposing to apply the existing requirements in 45 CFR 
156.221, 45 CFR 156.222, and 45 CFR 156.223, which were finalized in 
the 2020 CMS Interoperability and Patient Access final rule and in the 
2024 CMS Interoperability and Prior Authorization final rule (85 FR 
25510 and 89 FR 8758), to small group market QHP issuers on the FF-
SHOPs. We did not apply these policies to small group market QHP 
issuers on the FF-SHOPs in previous rulemaking due to concerns about 
placing burden on these issuers (85 FR 25553 and 89 FR 8767). However, 
based on subsequent research, all issuers that offer small group market 
QHPs on the FF-SHOPs, as of the time of this proposal, also offer 
individual market QHPs on the FFEs. Therefore, we anticipate that the 
burden for these issuers to implement these proposals for their small 
group market QHPs on the FF-SHOPs should be relatively low because 
these issuers are already required to implement the policies for their 
individual market QHPs on the FFEs. Since plan year 2021, we have only 
seen one instance of a new entrant into an FF-SHOP Exchange. However, 
should this change in the future--for example, if an issuer that does 
not offer one or more individual market QHPs on the FFEs newly enters 
an FF-SHOP, and this proposal has been finalized, we could still 
mitigate potential burden for such an issuer by considering whether an 
exception to one or more of these requirements is appropriate based on, 
for example, whether such an exception would be in the interests of 
qualified individuals and qualified employers.\12\
---------------------------------------------------------------------------

    \12\ For more information on interoperability and QHP 
certification, including further detail on the exceptions process, 
see https://www.qhpcertification.cms.gov/QHP/applicationmaterials/Interoperability. Discussion of this topic is also available in the 
2024 CMS Interoperability and Prior Authorization final rule 
preamble: 89 FR 8906.
---------------------------------------------------------------------------

    Throughout this proposed rule, we will refer to ``QHP issuers on 
the FFEs'' where we propose requirements that apply to both individual 
market QHP issuers on the FFEs and small group market QHP issuers on 
the FF-SHOPs, and we will refer to ``small group market QHP issuers on 
the FF-SHOPs'' in proposals to apply requirements in 45 CFR 156.221, 45 
CFR 156.222, and 45 CFR 156.223 that we previously finalized for 
individual market QHP issuers on the FFEs. We are proposing that 
references to QHP issuers on the FFEs in 45 CFR 156.221, 45 CFR 
156.222, and 45 CFR 156.223 would include small group market QHP 
issuers on the FF-SHOPs, because that term is used throughout 45 CFR 
part 156 Subpart C to refer to QHPs offered in both the individual and 
small group markets. We will only use different terminology in cases 
where there is a need to distinguish between individual market QHP 
issuers on the FFEs and small group market QHP issuers on the FF-SHOPs, 
such as in proposals to apply a different compliance date for small 
group market QHP issuers on the FF-SHOPs. For example, because the 
requirements in 45 CFR 156.221 already took effect for plan years 
beginning on or after January 1, 2021, our proposed amendment to that 
regulation would apply the requirements to implement and maintain a 
Patient Access API to small group market QHP issuers on the FF-SHOPs as 
of plan years beginning on or after January 1, 2028. We are also 
proposing a compliance date of plan years beginning on or after January 
1, 2028 for small group market QHP issuers on the FF-SHOPs to comply 
with rules in 45 CFR 156.222 to implement and maintain Provider Access 
and Payer-to-Payer APIs unless granted an exception pursuant to 45 CFR 
156.222(c). We believe that aligning these compliance dates would 
simplify these requirements, and that it likely provides enough time 
for issuers that have already implemented the required APIs for their 
individual market QHPs on the FFEs.
    The phrase ``plan years beginning on or after January 1'' already 
accommodates small group market QHP issuers on the FF-SHOPs that may 
have non-calendar year plan years. We solicit comments on the proposals 
throughout this rule specifically regarding the proposed compliance 
dates for small group market QHP issuers on the FF-SHOPs, including 
regarding whether these plans may need more time to implement these 
requirements. For instance, how could the prior authorization proposals 
in section II.B. of this proposed rule (electronic prior authorization 
proposal applicable to all QHP issuers on the FFEs) and II.C. of this 
proposed rule (prior authorization processes applicable to all QHP 
issuers on the FFEs) affect small group market QHP issuers on the FF-
SHOPs' ability

[[Page 19896]]

to meet the requirements proposed in section II.D. of this proposed 
rule (requirements for small group market QHP issuers on the FF-SHOPs), 
and vice versa?
    To support implementation of the policies finalized in the 2020 CMS 
Interoperability and Patient Access and 2024 CMS Interoperability and 
Prior Authorization final rules, we propose to require impacted payers 
to report their API endpoints for each of the required APIs to CMS. In 
response to the 2022 CMS Interoperability and Prior Authorization 
proposed rule, we received numerous comments from the public indicating 
that a centralized directory of API endpoints would be necessary to 
unlock the full potential of our electronic data exchange policies and 
reduce administrative burden (89 FR 8932). For instance, a centralized 
directory of API endpoints could help providers locate a payer's 
Provider Access API to request patient data or Prior Authorization API 
to submit a prior authorization request. In addition, payers will need 
to discover each other's API endpoints to exchange data via the Payer-
to-Payer API. Commenters emphasized that there would be a significant 
burden if payers' API endpoints had to be found individually rather 
than being listed in a centralized directory. Therefore, we are 
proposing to require impacted payers to report their Patient Access, 
Provider Directory, Provider Access, Payer-to-Payer, and Prior 
Authorization API endpoints and related information to CMS no later 
than 60 days after the effective date of a final rule, in a manner to 
be determined. We are also proposing that new impacted payers be 
required to report this information no later than 60 days before they 
begin covering patients under the applicable CMS program.
    To ensure that patients, providers, and other payers can have 
complete and appropriate access to information about prior 
authorizations, we are proposing to require impacted payers to make 
information about prior authorization requests and decisions for all 
drugs available to patients via the Patient Access, Provider Access, 
and Payer-to-Payer APIs (collectively ``Access APIs''). For the Patient 
Access and Provider Access APIs, this includes, as applicable, the 
status of the prior authorization; the date the prior authorization was 
approved or denied; the date or circumstance under which the 
authorization ends; the drug or drugs approved (including the dosage); 
if the prior authorization was denied, a specific reason why the 
request was denied; and related structured administrative and clinical 
documentation submitted by a provider. For the Payer-to-Payer API, that 
includes, as applicable, the status of the prior authorization; the 
date the prior authorization was approved; the date or circumstance 
under which the authorization ends; the drugs or drugs approved 
(including the dosage); and related structured and unstructured 
administrative and clinical documentation submitted by a provider, 
excluding denied prior authorization requests. We are proposing an 
October 1, 2027 compliance date for these proposals.
    In addition, we are proposing to add a definition for ``failure to 
report'' in 42 CFR 403.902 to support the Open Payments program. The 
Open Payments program, mandated by section 1128G of the Social Security 
Act (hereinafter referred to as ``the Act'') and codified in 42 CFR 
403.900 through 403.914, requires the pharmaceutical and medical device 
industry to submit information about certain payments or other 
transfers of value made to certain types of health care providers. This 
proposal would allow CMS to impose a CMP on applicable manufacturers or 
applicable GPOs if those entities fail to grant CMS timely access to 
documents for the purposes of an audit authorized by 42 CFR 
402.912(e)(2). We propose this definition be effective beginning on the 
effective date of the final rule.
    Under the Administrative Simplification provisions of HIPAA (Part C 
of Title XI of the Act), HHS is proposing to adopt the FHIR standard 
and certain associated IGs as the standards for dental, professional, 
and institutional ``referral certification and authorization'' 
transactions and ``eligibility for a health plan'' transactions 
associated with prior authorization. Specifically, in addition to the 
FHIR standard, HHS is proposing to adopt the HL7 FHIR US Core (US 
Core), HL7 Substitutable Medical Applications, Reusable Technologies 
(SMART) Application Launch Framework (SMART App Lauch), CRD, DTR, and 
PAS IGs in place of the adopted versions of the X12N 278 Health Care 
Services Review--Request for Review and Response transaction standard 
(X12N 278 transaction standard) in 45 CFR 162.1302 and the existing 
X12N 270/271 Health Care Eligibility Benefit Inquiry and Response 
transaction standard (X12N 270/271 transaction standard) in 45 CFR 
162.1202 for transactions related to prior authorization. Additionally, 
HHS is proposing to adopt the HL7 FHIR Da Vinci Clinical Data Exchange 
(CDex) IG in 45 CFR 162.1302(g)(2)(vii) as the attachment standard for 
prior authorization transactions. The proposals to adopt the FHIR 
standards would only apply to dental, professional, and institutional 
transactions, not to those for retail pharmacy drugs, which are 
currently required to be conducted using NCPDP standards. HHS proposes 
a compliance date for these HIPAA Administrative Simplification 
proposals 24 months after the effective date of a final rule, except 
for small health plans, for which HHS proposes a compliance date 36 
months after the effective date of a final rule. HHS is making these 
proposals after evaluating the results of the exception from the 
currently adopted standards granted to the HL7 Da Vinci Project, as 
provided in 45 CFR 162.940, to test FHIR standards.\13\

    As part of this proposed rule, ONC \14\ is proposing to adopt 
updated versions of certain health IT standards and specifications in 
45 CFR 170.215 on behalf of HHS. Specifically, ONC is proposing to 
adopt updated versions of the health IT standards and specifications 
codified in 45 CFR 170.215(j)(1) through (3), (k)(1), (m), and (n), 
which CMS is proposing to require impacted payers to use. Additionally, 
ONC is proposing a January 1, 2028 expiration date for versions of the 
standards and specifications currently in 45 CFR 170.215(j)(1) through 
(3), (k)(1), (m), and (n), provided that the proposals to adopt the 
newer versions of these adopted standards are finalized. These updated 
standards versions could support a more robust health IT 
infrastructure, create consistency for industry, and facilitate 
interoperability by ensuring that health IT leveraging these standards 
under different HHS programs use the same baseline standards for the 
same use cases, such as electronic prior authorization.
---------------------------------------------------------------------------

    \14\ ASTP/ONC is now referred to as ONC, pursuant to a notice 
which appeared in the Federal Register on April 1, 2026 (91 FR 
16204). Although, at the time of specific references noted herein, 
ONC was either referenced as ASTP/ONC or as ONC, for clarity, all 
references in this document are now noted as ONC.
---------------------------------------------------------------------------

    Finally, we are publishing five requests for information (RFIs) to 
gather information that may support future rulemaking or other 
initiatives. The RFIs are related to electronic event notifications for 
value-based care and care coordination, health care resiliency and 
securing health care operations in a modern health care ecosystem, 
improving the implementation of payer API technology through testing 
and

[[Page 19897]]

certification, using technology to manage step therapy, and prior 
authorization requirements for laboratory tests and durable medical 
equipment, prosthetics, orthotics, and supplies (DMEPOS) items.
    Electronic event notifications are valuable tools for coordinating 
care in the modern health care environment, and we are seeking comment 
on ways to improve this process with expanded use and content of 
electronic event notifications (often referred to as admission, 
discharge, and transfer, or ``ADT'' notifications). We want to 
understand the types of providers or other entities that should receive 
ADT notifications along with technical approaches that are currently in 
use or that could be used for patient event notifications. We also seek 
comments on health IT certification criteria for notification 
capabilities and strengthening enforcement of ADT notification 
requirements.
    Hacking, ransomware, and other cybersecurity attacks on health care 
systems and electronic protected health information (ePHI) present an 
ever-increasing threat. These attacks have already caused, and could 
continue to cause, significant disruption to the health care industry, 
potentially resulting in significant harm to patients, providers, 
payers, and the health care ecosystem at large. We are seeking feedback 
on opportunities to strengthen, protect, and increase the resiliency of 
our health care system in cybersecurity spaces to prevent and better 
handle future threats. Additionally, we would like to hear about 
existing standards and technologies, as well as the current role of 
point-to-point connections within the health care system.
    Monitoring compliance and technical conformance with standards is 
critical to effective interoperability within the health care ecosystem 
based on the API requirements that we have established for impacted 
payers. We are seeking comment on steps that we could take to improve 
oversight of payer APIs, for instance, through strengthening testing 
and transparency requirements. We are also exploring opportunities to 
leverage existing programs, such as the ONC Health IT Certification 
Program, to ensure that API technology used by payers meets the 
technical requirements we establish.
    We are also seeking comments on ways to streamline the step therapy 
process through technology and data sharing (such as the Payer-to-Payer 
API) to allow payers access to historical patient information. We seek 
comment on how technology may facilitate step therapy determinations 
and improve current step therapy processes. This includes the role of 
technology in evaluating and applying step therapy criteria and how 
payers evaluate and honor step therapy criteria from other payers.
    Prior authorization requirements for laboratory tests and DMEPOS 
items have emerged, in some instances, as a barrier to care and 
coverage that impacts both patients and providers. The primary issues 
associated with prior authorization for laboratory tests and DMEPOS 
items are coordination between providers and laboratories or DMEPOS 
suppliers and the length of time approval takes for tests and 
equipment. We are soliciting public comment on how prior authorization 
for laboratory tests and DMEPOS items impacts patient care and provider 
burden and what can be done to mitigate that burden.

C. Specific Terms Used in This Proposed Rule

    Throughout this proposed rule, we use terms such as ``patient,'' 
``consumer,'' ``beneficiary,'' ``enrollee,'' and ``individual.'' In 
this proposed rule, we use the term ``patient'' as an inclusive term. 
Each CMS program may use different terms to refer to patients in 
regulation. Therefore, in this proposed rule, we use ``patients'' 
collectively across programs. However, when discussing proposals for a 
particular program, we will use specific terms applicable to 
individuals covered under that program. Also, when we discuss patients, 
the term includes, where applicable, a patient's personal 
representative. For example, a patient or their personal representative 
may access certain types of information under the proposals in this 
proposed rule. However, when we refer to a patient's medical needs or 
health records, we do not include the medical needs or health records 
of the patient's personal representative. Pursuant to the ``Standards 
for Privacy of Individually Identifiable Health Information'' final 
rule (65 FR 82462) (hereinafter referred to as the ``HIPAA Privacy 
Rule''), which appeared in the Federal Register on December 28, 2000, 
45 CFR 164.502(g), and related guidance, a ``personal representative'' 
is a person authorized under state or other applicable law to act on 
behalf of an individual in making health care-related decisions (such 
as a parent, guardian, or person with a medical power of 
attorney).15 16 Under the HIPAA Privacy Rule, the 
individual's personal representative generally may exercise the right 
to access the individual's protected health information (PHI).

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

    We also use terms such as ``payer,'' ``plan,'' and ``issuer'' in 
this proposed rule. Certain portions of this proposed rule are 
applicable to MA organizations, state Medicaid and CHIP FFS programs, 
Medicaid managed care plans (managed care organizations [MCOs], Prepaid 
Inpatient Health Plans [PIHPs], and Prepaid Ambulatory Health Plans 
[PAHPs]), CHIP managed care entities (MCOs, PIHPs, and PAHPs), QHP 
issuers on the FFEs, including proposals for small group market QHP 
issuers on the FF-SHOPs. We use the term ``impacted payer'' in the 
preamble of this proposed rule as an inclusive term for all these 
entities and programs and, in the case of plans, plan types, but we 
also use specific terms as applicable in various sections of this 
proposed rule. Notably, the term ``impacted payers'' only applies to 
the CMS proposals in this proposed rule, not to the HHS proposals for 
HIPAA Administrative Simplification. As discussed in section II.H. of 
this proposed rule, the HIPAA Administrative Simplification proposals 
would apply to HIPAA covered entities, as described in section 1172(a) 
of the Act and defined in 45 CFR 160.103.
    Some plans that participate in those CMS programs may not be 
permitted to use prior authorization (such as Private FFS MA plans) or 
may choose not to use prior authorization. Our prior authorization 
proposals only apply to the extent that a payer (or plan) uses prior 
authorization. Therefore, if an impacted payer does not use prior 
authorization, they would not be subject to the prior authorization 
proposals. However, other proposals, such as those related to the 
Access APIs and standards, would apply to all types of plans under the 
categories of impacted payers.
    Many payers use a pharmacy benefit manager (PBM) to manage 
prescription drug benefits on their behalf, including through 
utilization management techniques such as prior authorization. These 
proposals do not apply directly to PBMs, but we understand that, if 
these proposals are finalized, PBMs may play a role in helping impacted 
payers meet the requirements proposed in this rule. For example, if a 
PBM is contracted by an impacted payer to manage its prescription drug 
benefits, including to

[[Page 19898]]

conduct prior authorization, it may make sense for the payer to have 
providers send prior authorization requests for those drugs directly to 
the PBM. In that case, if finalized, the PBM would be required to 
support an unexpired version of the NCPDP SCRIPT standard adopted by 
the Secretary in 45 CFR 170.205(b) for the electronic prior 
authorization of drugs, thereby making electronic prior authorization 
available to providers and meeting the proposed requirement on behalf 
of the impacted payer. Such arrangements would be permissible under 
these proposals, if allowed under applicable program rules. However, we 
emphasize that the ultimate responsibility for regulatory compliance 
would be on impacted payers themselves.
    Although Medicare FFS is not directly affected by the CMS 
interoperability regulations, CMS continues to explore and initiate 
opportunities to enhance electronic prior authorization within the 
Medicare FFS program, as appropriate, including those for drugs. The 
Medicare FFS program has developed a Prior Authorization API that makes 
available Medicare coverage criteria rules and documentation 
requirements to providers. This API helps providers determine whether 
prior authorization is required and identify the necessary 
documentation. The API also facilitates the extraction of relevant 
clinical information from the provider's electronic health record (EHR) 
to compile the required documentation and enables the electronic 
submission of prior authorization requests in a structured format to 
CMS review contractors. We want to ensure that Medicare beneficiaries 
can benefit from the policies we are proposing, regardless of their 
coverage or delivery system. We intend for the Medicare FFS program to 
be a market leader on electronic prior authorization and therefore, 
seek comment throughout this proposed rule on how these proposals could 
apply to Medicare FFS. In addition, Medicare FFS is a HIPAA covered 
entity, subject to the HIPAA Administrative Simplification statutory 
provisions. Therefore, if HHS' proposals in section II.H. are 
finalized, Medicare FFS would be subject to the electronic transaction 
standards adopted by the Secretary.
    As was the case for the 2020 CMS Interoperability and Patient 
Access and the 2024 CMS Interoperability and Prior Authorization final 
rules, Medicare Supplemental Insurance plans (commonly known as 
Medigap) are not impacted payers. Medigap plans do not perform prior 
authorization but rely on coverage determinations by Medicare FFS. In 
addition, as stated in the 2020 CMS Interoperability and Patient Access 
final rule, Program of All-Inclusive Care for the Elderly (PACE) 
organizations are not impacted payers under the CMS interoperability 
rules (85 FR 25621).
    For purposes of this proposed rule, references to QHP issuers on 
the FFEs exclude issuers offering stand-alone dental plans (SADPs) on 
the FFEs. In the 2024 CMS Interoperability and Prior Authorization 
final rule, we did not propose or finalize requirements applicable to 
SADP issuers because they have relatively lower enrollment and premium 
intake compared to individual market QHP issuers on the FFEs. In 
addition, we had concerns that requiring those plans to comply with the 
final rule's policies could result in those issuers no longer 
participating in the FFEs, which would not be in the best interest of 
enrollees (89 FR 8766). Several public comments also made this point, 
that a requirement for SADP issuers to implement the required FHIR APIs 
would impose burden with minimal or no benefit (85 FR 25552 and 25553). 
Additionally, SADP issuers are not required to cover prescription 
drugs. When a dental provider writes a prescription, that drug is 
generally processed through the enrollee's non-dental medical benefit. 
Although dental providers may provide medication as part of a dental 
procedure, such as local anesthesia, it is our understanding that this 
is generally part of the dental procedure itself and therefore dental 
providers are reimbursed for the service as a bundle rather than 
through a separate claim for drugs. Therefore, we are not proposing to 
apply requirements to SADP issuers, but we solicit comment on whether 
the considerations described previously do in fact diminish the need 
for electronic prior authorization requirements and prior authorization 
process requirements for SADP issuers. We solicit comments on whether 
we should consider future rulemaking to apply these proposed 
requirements and those finalized in the 2024 CMS Interoperability and 
Prior Authorization final rule to SADP issuers.
    For the purposes of this proposed rule, FFEs include FFEs in states 
that perform plan management functions, and as noted in the 2024 CMS 
Interoperability and Prior Authorization final rule, State-based 
Exchanges on the Federal Platform (SBE-FPs) are not FFEs, even though 
patients in those states enroll in coverage through HealthCare.gov (89 
FR 8761). Hence, issuers in SBE-FPs would not be impacted payers 
subject to the CMS proposals in this proposed rule. We believe that it 
is appropriate at this time to continue to exclude issuers on the 
State-based Exchanges (SBEs), including SBE-FPs, as impacted payers to 
keep with prior interoperability rulemaking. As we assess the 
effectiveness of interoperability policies, we will consider whether 
future rulemaking to include those types of issuers as impacted payers 
is appropriate, as we are proposing now for small group market QHP 
issuers on the FF-SHOPs. Importantly, we will be informed by the 
Patient Access API usage metrics required in 45 CFR 156.221(f), and, if 
finalized, the proposed Provider Access, Payer-to-Payer, and Prior 
Authorization API usage metrics discussed in section II.F.2.c. of this 
proposed rule. This data, as well as information we receive from 
issuers applying for QHP certification about their interoperability 
activities, will help us to understand how patients, providers, and 
payers use these tools and the success of current requirements. We also 
solicit comment in this proposed rule on whether to consider future 
rulemaking to extend these proposals, and those policies finalized in 
the 2020 CMS Interoperability and Patient Access and the 2024 CMS 
Interoperability and Prior Authorization final rules, to issuers that 
offer coverage through SBE-FPs, SBEs, or both. In the 2024 CMS 
Interoperability and Prior Authorization final rule, we encouraged 
these Exchanges to consider adopting similar requirements (89 FR 8761), 
and, in this proposed rule, we solicit comment on the extent to which 
they have or may do so, as well as potential feasible deadlines for 
issuers in those Exchanges to implement interoperability requirements, 
so their enrollees can benefit from access to their health care data 
and more efficient and timely prior authorization processes.
    In this proposed rule, we use the terms ``provider'' and 
``supplier'' to mean individuals, organizations, and institutions that 
provide or furnish health services, such as clinicians (that is, 
physicians and other practitioners), hospitals, skilled nursing 
facilities (SNFs), home health agencies, hospice settings, 
laboratories, pharmacies, suppliers of DMEPOS items, and community-
based organizations, as appropriate in the context used. Similarly, we 
are generally not using the term ``prescriber'' in this rule, as 
``provider'' is a broader term that includes any individual who 
authorizes a particular prescription or order. Our proposals related to 
the prior authorization of drugs are discussed in the context of 
providers who request

[[Page 19899]]

prior authorization from a payer, which may or may not be the actual 
prescriber.
    Many of the existing and proposed interoperability standards are 
based on API technology. An API is a set of rules that lets different 
software systems communicate with each other. It defines how one 
program (a client, often an app) can request data or services from 
another system (a server), and how the response should be structured. 
APIs are commonly used to connect apps. For example, a health app can 
use an API implemented within a payer's system to request and receive a 
specific patient's data. This allows developers to build on and 
communicate with existing systems without needing to understand their 
internal workings. APIs are essential for building modern, integrated 
digital experiences in a variety of industries, including health care, 
banking, and e-commerce.\17\

Information Technology. (n.d.). Application Programming Interfaces. 
Retrieved from https://www.healthit.gov/api-education-module/story_html5.html.
---------------------------------------------------------------------------

    Throughout this rule, we collectively refer to the APIs finalized 
in the 2020 CMS Interoperability and Patient Access and 2024 CMS 
Interoperability and Prior Authorization final rules--the Patient 
Access, Provider Directory, Provider Access, Payer-to-Payer, and Prior 
Authorization APIs--as the ``interoperability APIs.'' When we refer to 
``access APIs,'' we mean those that are used primarily to access a 
specific patient's health record, the Patient Access, Provider Access, 
and Payer-to-Payer APIs. Each of the interoperability APIs are required 
to be built using the FHIR standard. FHIR is a standards framework 
created by HL7 to electronically exchange health information via APIs 
using the latest technology standards. FHIR defines categories of data, 
called ``Resources'' that, individually or in combination, satisfy most 
common use cases. The Patient Resource, for example, includes 
demographic data related to a patient, such as their name, address, and 
phone number. Using these FHIR Resources enables granular data 
retrieval, so that a request returns just the relevant data rather than 
a full record or document that itself must then be searched. Once they 
are modified for specific requirements using FHIR's built-in 
capabilities, combinations of Resources are brought together in an IG 
to address a specific use case, such as a provider directory or prior 
authorization. This structure lends itself well to expansion beyond 
FHIR's core capabilities.\18\

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

    As in the 2024 CMS Interoperability and Prior Authorization final 
rule, we use the term ``prior authorization'' to refer to the process 
through which a provider, such as an individual clinician, acute care 
hospital, ambulatory surgical center, or clinic, obtains approval from 
a payer before providing care (89 FR 8761). A prior authorization is 
made up of two parts--a request from a provider and a decision/response 
by a payer. We refer to the provider's workflow and associated 
information and documentation as the ``prior authorization request'' 
and the payer's processes and associated information and documentation 
as the ``prior authorization decision.'' Payers establish prior 
authorization requirements to help control costs and ensure payment 
accuracy by verifying that an item, service, or drug is medically 
necessary for the specific patient, meets coverage criteria, and, for 
some payers, is consistent with standards of care before being 
provided. As we explained in the 2024 CMS Interoperability and Prior 
Authorization final rule, prior authorization has an important place in 
the health care system for utilization management, but the process and 
delays continue to be challenging for providers (89 FR 8914). 
Furthermore, issuers with complex payer policies, inconsistent use of 
electronic standards, and other technical barriers create provider 
workflow challenges and an environment in which the prior authorization 
process is a primary source of burden for both providers and payers and 
can create a health risk for patients if they don't receive medically 
necessary care in a timely manner.
    In this proposed rule, we refer to two categories of drugs--``drugs 
covered under a pharmacy benefit'' and ``drugs covered under a medical 
benefit.'' We acknowledge that these terms do not have statutory or 
regulatory correlations for impacted payers other than MA organizations 
(based on the distinctions between Parts A, B, and D). For instance, 
for Medicaid and CHIP, we propose that the distinction can be 
distinguished by the systems used to process claims. We are using 
``drugs covered under a pharmacy benefit'' to reflect how the NCPDP 
SCRIPT standard describes the category of drugs within its scope.\19\ 
Conversely, we are using ``drugs covered under a medical benefit'' to 
describe the category of drugs for which the NCPDP SCRIPT standard is 
not to be used, pursuant to the IG, but is within the scope of the 
Prior Authorization API, based on instructions in the PAS IG, which 
states that the IG ``SHOULD NOT be used for any medication that is 
covered under a pharmacy benefit where prior authorization is provided 
by another electronic exchange process (for example, NCPDP SCRIPT).'' 
These standards and their scopes are further discussed in sections 
II.A.2. and II.A.3. of this proposed rule. We request comment on 
whether there are drugs covered by any impacted payer that may not fit 
into the categories ``drugs covered under a medical benefit'' and 
``drugs covered under a pharmacy benefit'' and how such drugs can be 
included in one of those two categories.
---------------------------------------------------------------------------

    \19\ See 89 FR 51262.
---------------------------------------------------------------------------

    When we refer to both drugs covered under a pharmacy benefit and 
drugs covered under a medical benefit, throughout this rule we use the 
terms ``all drugs'' or ``any drugs.'' Further discussion of these terms 
is included in the discussion of those standards in section II.A. of 
this proposed rule.
    HL7 is an American National Standards Institute (ANSI)-accredited 
SDO that develops the FHIR standard and the IGs referenced throughout 
this proposed rule. In addition, they are a designated standard 
maintenance organization (DSMO), designated by the Secretary under 45 
CFR 162.910.\20\ NCPDP is a non-profit ANSI-accredited SDO supporting 
standards for the drug supply chain. The NCPDP SCRIPT, F&B, and RTPB 
standards are established standards that can support prior 
authorization and other prescription information exchange tasks for 
drugs covered under a pharmacy benefit, as described further in 
sections II.A. and II.B. of this proposed rule.

D. Severability

    In this proposed rule, CMS and HHS propose a variety of policies 
related to prior authorization. To the extent a court may enjoin one 
provision of this final rule, CMS and HHS propose that the other 
provisions should remain in effect, ensuring the continuity of the 
regulations. We propose that any provision of the requirements of this 
rule that is held to be invalid or unenforceable by its terms or as 
applied to any person or circumstance would be construed so as to 
continue to give maximum effect to the provision permitted by law, 
unless such holding is one of utter invalidity or unenforceability, in 
which event we

[[Page 19900]]

propose that the provision would be severable from the other provisions 
of this rulemaking and would not affect the remainder thereof or the 
application of the provision to persons not similarly situated or to 
dissimilar circumstances.
    We propose that if any section, subsection, sentence, clause, 
phrase, word, provision, or application of this final rule shall be 
found to be invalid, illegal, unconstitutional, or unenforceable, that 
finding shall not affect or undermine the validity of any other 
section, subsection, sentence, clause, phrase, word, provision, or 
application which can be enforced without the use of the offending 
provision. We request comments from the public on severability, 
particularly which policies could be severable, if finalized, and how 
the other policies in a final rule would operate absent those 
particular provisions.

II. Provisions of the Proposed Rule

A. Interoperability Standards for APIs

1. Background
    Standards set the foundation for consistent technical 
implementation to support interoperable exchange of information, which 
facilitates efficient, safe, and high-quality care for patients. In the 
2024 CMS Interoperability and Prior Authorization final rule, we 
require impacted payers to use API technology conformant with specific 
standards in 45 CFR 170.215 applicable to the interoperability APIs (89 
FR 8927). We finalized requirements to use these standards through 
cross-references to 45 CFR 170, subpart B, where ONC adopts standards 
that may be used across HHS programs. Those standards, which are 
applicable to different APIs, include the following:
     Health Level Seven (HL7[supreg]) Fast Healthcare 
Interoperability Resources (FHIR[supreg]), Release 4.0.1 in 45 CFR 
170.215(a)(1);
     HL7 FHIR US Core IG, Standard for Trial Use (STU) 3.1.1 in 
45 CFR 170.215(b)(1)(i) (US Core IG);
     HL7 Substitutable Medical Applications, Reusable 
Technologies (SMART) Application Launch Framework IG, Release 1.0.0 in 
45 CFR 170.215(c)(1) (SMART App Launch IG);
     FHIR Bulk Data Access (Flat FHIR) IG, v1.0.0: STU 1 in 45 
CFR 170.215(d)(1) (Bulk Data Access IG); and
     OpenID Connect Core 1.0, incorporating errata set 1, in 45 
CFR 170.215(e)(1) (OpenID Connect Core).
    The specific standards for the interoperability APIs are listed in 
Table H3 of the 2024 CMS Interoperability and Prior Authorization final 
rule (89 FR 8945). In that same final rule, we finalized policies that 
allow impacted payers to use updated standards for these APIs, if 
specific conditions are met, which are similar to policies previously 
finalized in the 2020 CMS Interoperability and Patient Access final 
rule.\21\ We also strongly recommended payers use additional IGs for 
each API, listed in Table H3 (89 FR 8945).
---------------------------------------------------------------------------

    \21\ See 42 CFR 422.119(c)(4)(ii) for MA organizations, 42 CFR 
431.60(c)(4)(ii) for state Medicaid FFS programs; through cross 
references to 42 CFR 431.60 in 42 CFR 438.242(b)(5), 42 CFR 
431.61(a) in 42 CFR 438.242(b)(7), 42 CFR 431.61(b)(1) in 42 CFR 
438.242(b)(7), 42 CFR 431.70 in 42 CFR 438.242(b)(6), 42 CFR 
431.80(b) in 42 CFR 438.242(b)(7) for Medicaid managed care plans; 
42 CFR 457.730(c)(4)(ii) for state CHIP FFS programs; through cross 
reference to 42 CFR 438.242 in 42 CFR 457.1233(d) for CHIP managed 
care entities; and 45 CFR 156.221(c)(4)(ii) for individual market 
QHP issuers.
---------------------------------------------------------------------------

    The ``Health Data, Technology, and Interoperability: Certification 
Program Updates, Algorithm Transparency, and Information Sharing'' 
proposed and final rules (88 FR 23746 and 89 FR 1192) (hereinafter 
referred to as the ``HTI-1 proposed rule'' and the ``HTI-1 final 
rule''), appeared in the Federal Register on April 18, 2023 and January 
9, 2024, respectively. In that rulemaking, which took place between the 
2022 and 2024 CMS Interoperability and Prior Authorization proposed and 
final rules, the Secretary adopted updated versions of several 
standards set forth in 45 CFR 170.215 and finalized expiration dates 
for previous versions of standards. As a result, the 2024 CMS 
Interoperability and Prior Authorization final rule finalized 
requirements for impacted payers to use standards in 45 CFR 170.215 
available at the time of the 2022 CMS Interoperability and Prior 
Authorization proposed rule, and not versions subsequently proposed and 
finalized by the Secretary. Some of those required versions now have 
established expiration dates.
    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we finalized requirements to use the versions of the standards in 
45 CFR 170.215 that we had proposed, not those that were newly adopted 
in the HT1-1 final rule. For example, when the 2022 CMS 
Interoperability and Prior Authorization proposed rule appeared in the 
Federal Register on December 13, 2022, the US Core IG, STU 3.1.1 and 
SMART App Launch IG, Release 1.0.0 were the current versions of these 
standards. In the 2024 CMS Interoperability and Prior Authorization 
final rule, we finalized a requirement that impacted payers must use 
the versions set forth in the proposed rule (which had not yet expired 
on the date the final rule appeared in the Federal Register), although 
the Secretary adopted newer versions (US Core IG, STU 6.1.0 in 45 CFR 
170.215(b)(1)(ii) and SMART App Launch IG, Release 2.0.0 in 45 CFR 
170.215(c)(2)) in the HTI-1 final rule (89 FR 1284, 1285, and 1291).
    The Secretary also finalized a January 1, 2026 expiration date for 
the US Core IG, STU 3.1.1 (in 45 CFR 170.215(b)(1)(i)) and the SMART 
App Launch IG, Release 1.0.0 (in 45 CFR 170.215(c)(1)). Upon the 
specified expiration date, the expired versions of the standards are no 
longer eligible for certification of Health IT Modules through the ONC 
Health IT Certification Program (89 FR 1285 and 1292). As of this 
proposed rule, there are two adopted versions of the US Core IG: (1) 
the US Core IG, STU 3.1.1 (in 45 CFR 170.215(b)(1)(i)), which expired 
on January 1, 2026, and (2) the US Core IG, STU 6.1.0 (in 45 CFR 
170.215(b)(1)(ii)) without an expiration date.
    Through our proposals in this rule, we are seeking to align with 
the regulatory framework established by ONC to adopt, update, and 
expire health IT standards incorporated by reference in the Code of 
Federal Regulations (CFR). Accordingly, under our proposals, if ONC 
establishes an expiration date for an adopted standard, or for a 
specific version thereof, in subpart B of 45 CFR part 170, upon the 
specified expiration date, impacted payers would no longer be permitted 
to use that standard or version to meet the interoperability 
requirements. We believe these proposals will support greater alignment 
across interoperability standards requirements that impact payers, 
health care providers, health IT developers and other parties.
    In the 2020 CMS Interoperability and Patient Access and 2024 CMS 
Interoperability and Prior Authorization final rules, we also finalized 
policies that allow impacted payers to voluntarily conform with updated 
versions of the standards we have required payers to use in 45 CFR 
170.213 and 45 CFR 170.215 (such as the US Core IG and SMART App Launch 
IG), provided that (1) the National Coordinator for Health Information 
Technology (hereinafter referred to as the ``National Coordinator'') 
has approved the updated version for use in the ONC Health IT 
Certification Program; (2) the updated version of the standard does not 
disrupt an end user's ability to access the required data via that API; 
and (3) the updated standard is not prohibited by law (85 FR 25532 and 
89 FR 8946). In addition, impacted payers may use an

[[Page 19901]]

updated version if required by other applicable law.\22\ Under these 
provisions, impacted payers may upgrade to newer versions of the 
required standards, subject to the specified limiting conditions (85 FR 
25532 and 89 FR 8946).
---------------------------------------------------------------------------

    \22\ See 42 CFR 422.119(c)(4)(ii) for MA organizations, 42 CFR 
431.60(c)(4)(ii) for state Medicaid FFS programs; through cross 
references to 42 CFR 431.60 in 42 CFR 438.242(b)(5), 42 CFR 
431.61(a) in 42 CFR 438.242(b)(7), 42 CFR 431.61(b)(1) in 42 CFR

reference to 42 CFR 438.242 in 42 CFR 457.1233(d) for CHIP managed 
care entities; and 45 CFR 156.221(c)(4)(ii) for individual market 
QHP issuers.
---------------------------------------------------------------------------

    Finally, in the 2022 CMS Interoperability and Prior Authorization 
proposed rule, we did not propose, nor did we finalize any requirements 
in the 2024 CMS Interoperability and Prior Authorization final rule, 
that applied to any drugs because, as we discussed in the proposed and 
final rules, the processes and standards for prior authorization of 
drugs differ from the non-drug items and services included in our final 
policies (89 FR 8762). However, we received many public comments in 
response to the 2022 CMS Interoperability and Prior Authorization 
proposed rule, as well as additional feedback from providers, payers, 
and SDOs, indicating that while some prior authorization processes and 
standards for drugs currently exist, patients and other stakeholders 
would benefit from consistent requirements to provide patients timely 
access to drugs, and from a streamlined electronic prior authorization 
process that alleviates burden for providers and impacted payers.
2. NCPDP Standards for Prior Authorization of Drugs Covered Under a 
Pharmacy Benefit
a. NCPDP SCRIPT Standard
    After considering stakeholder comments on the 2022 CMS 
Interoperability and Prior Authorization proposed rule, our goals for 
interoperability across impacted payers, and the technical standards 
available to support electronic prior authorization for drugs, we are 
now proposing to require impacted payers to support electronic prior 
authorization for drugs. We are proposing to require impacted payers to 
use either the FHIR standards and IGs required for the Prior 
Authorization API or the NCPDP SCRIPT standard depending upon whether 
the drugs are covered under a medical benefit or a pharmacy benefit, as 
detailed by the standards implementation specifications, and further 
discussed below.
    As discussed further in section II.B. of this proposed rule, we are 
proposing to require state Medicaid and CHIP FFS programs, Medicaid 
managed care plans, CHIP managed care entities, and QHP issuers on the 
FFEs to support an unexpired version of the NCPDP SCRIPT Standard 
Implementation Guide (NCPDP SCRIPT) \23\ adopted by the Secretary in 45 
CFR 170.205(b) for the electronic prior authorization of drugs covered 
under a pharmacy benefit. In the ``Medicare Program; Medicare 
Prescription Drug Benefit Program; Health Information Technology 
Standards and Implementation Specifications'' final rule (89 FR 51238) 
(hereinafter referred to as the ``2024 Part D and Health IT Standards'' 
final rule), which appeared in the Federal Register on June 17, 2024, 
ONC finalized a January 1, 2028 expiration date for the NCPDP SCRIPT 
Standard Implementation Guide, Version 2017071 in 45 CFR 170.205(b)(1), 
and adopted the NCPDP SCRIPT Standard Implementation Guide, Version 
2023011 in 45 CFR 170.205(b)(2) (89 FR 51244 and 51258-51259). Like the 
approach discussed above for required standards for payer APIs, our 
proposals in this rule seek to align to ONC's framework to adopt and 
update versions of the SCRIPT standard. Under these proposals, if ONC 
establishes an expiration date for the NCPDP SCRIPT standard in 45 CFR 
170.205(b), or for a specific version thereof, upon the specified 
expiration date, impacted payers would no longer be permitted to use 
that standard or version to meet the interoperability requirements. We 
are proposing an October 1, 2027 compliance date for this proposed

    NCPDP is a not-for-profit ANSI-accredited SDO representing the 
pharmacy services industry and is responsible for developing and 
maintaining standards for the exchange of information between 
providers, pharmacies, and payers. NCPDP is an SDO for pharmacy 
standards, including billing, subrogation, formulary and benefits, 
electronic prior authorization, electronic prescribing, and real-time 
benefit checks. The NCPDP SCRIPT standard can be used for multiple 
transactions between entities during the prescribing and dispensing 
processes including between providers, pharmacies, and payers for 
electronic prescribing; electronic prior authorization; and medication 
history exchange. This proposed rule focuses only on the electronic 
prior authorization functionality of the standard.
    The NCPDP SCRIPT standard is the most widely used standard by 
providers and payers for electronic prescribing and electronic prior 
authorization for drugs covered under a pharmacy benefit. The NCPDP 
SCRIPT standard can be used by providers to submit a prior 
authorization request to the payer (including the payer's processor or 
PBM, as appropriate). The NCPDP SCRIPT standard is designed 
specifically and solely for a category of drugs, which are described as 
``drugs covered under a pharmacy benefit.'' \24\ The transactions in 
the NCPDP SCRIPT standards for electronic prior authorization are not 
intended to be used to communicate information for medical items or 
services or drugs covered under a medical (non-pharmacy) benefit.

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

    (1) Scope of the NCPDP SCRIPT Standard and FHIR IGs for Electronic 
Prior Authorization of Drugs
    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we finalized a policy that established HL7 FHIR, Release 4.0.1 as 
the API base standard for the Prior Authorization API.\25\ 
Specifically, we finalized that certain impacted payers must implement 
and maintain the Prior Authorization API, and that the Prior 
Authorization API use the HL7 FHIR standard, Release 4.0.1 for 
electronic prior authorization of non-drug items and services (89 FR 
8859 and 8861). We also strongly recommended that impacted payers use 
the HL7 FHIR Da Vinci Coverage Requirements Discovery (CRD) IG, the HL7 
FHIR Da Vinci Documentation Templates and Rules (DTR) IG, and HL7 FHIR 
Da Vinci Prior Authorization Support (PAS) IG when implementing the 
Prior Authorization API (89 FR 8863). These FHIR IGs are technically 
capable of supporting prior authorization of non-drug items and 
services and drugs covered under a medical benefit. The FHIR 
specifications, specifically the PAS IG, states that it ``SHOULD NOT be 
used for any Medication that is covered under a pharmacy benefit where 
prior authorization is provided by another electronic exchange process 
(for

[[Page 19902]]

example, NCPDP SCRIPT).'' 26 27 That directive is intended 
to differentiate the scope of the FHIR IGs for prior authorization from 
the scope of the NCPDP SCRIPT standard, which is used for prior 
authorization of drugs under a pharmacy benefit.

IGs for the Prior Authorization API.

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

    The 2024 Part D and Health IT Standards final rule requires 
prescribers, dispensers, and Part D sponsors (as part of their 
electronic prescription drug programs) to use a version of the NCPDP 
SCRIPT standard adopted in 170.205(b) to transmit electronic prior 
authorization for covered Part D drugs for Part D eligible individuals 
(89 FR 51239). Any drugs covered by MA plans other than covered Part D 
drugs, that is, drugs payable under Part A or Part B, are not within 
the scope of the NCPDP SCRIPT standard and instead are within the scope 
of the Prior Authorization API (using HL7 FHIR, Release 4.0.1). 
However, we acknowledge that for state Medicaid and CHIP FFS programs, 
Medicaid managed care plans, CHIP managed care entities, and QHP 
issuers on the FFEs, there is currently no statutory or regulatory 
definition that distinguishes between drugs covered under a pharmacy 
benefit and drugs covered under a medical benefit, as described in the 
NCPDP SCRIPT or Da Vinci FHIR IGs for electronic prior authorization. 
Therefore, if these proposals, found in sections II.A.2. and II.B.3. of 
this proposed rule, are finalized as proposed, we anticipate that state 
Medicaid and CHIP FFS programs, Medicaid managed care plans, CHIP 
managed care entities, and QHP issuers on the FFEs would analyze their 
list of covered drugs for which they require prior authorization and 
determine whether electronic prior authorization for each drug could be 
supported by the NCPDP SCRIPT standard or should instead be provided 
through the Prior Authorization API. Drugs covered under a pharmacy 
benefit, which would use the NCPDP SCRIPT standard for electronic prior 
authorization requests, are often those medications dispensed at a 
retail pharmacy. Drugs covered under a medical benefit, which would use 
the Prior Authorization API, are often those dispensed by a medical 
provider in a health care setting. We understand that the same drug 
could fall into different categories for different impacted payers 
based on their terms of coverage, but we do not think that would 
undermine this proposal's effectiveness because impacted payers could 
indicate which method a provider should use to submit a particular 
prior authorization.
    The CRD IG has the technical capability to return specific coverage 
information through the ``CoverageInformation'' extension, and we seek 
comment on how the ``CoverageInformation'' extension could best be 
utilized to indicate whether a particular drug is covered under a 
medical benefit and, therefore, that the Prior Authorization API should 
be used for electronic prior authorization. Similarly, we seek comment 
on whether the impacted payers could utilize the NCPDP Real-Time 
Prescription Benefit (RTPB) standard to indicate whether a drug is 
covered under a medical benefit. We also solicit comment on whether 
there are existing technical solutions or methods that show promise but 
would require additional development that impacted payers could utilize 
to indicate to providers how a prior authorization request for a drug 
should be submitted. In addition, we discuss below how the NCPDP 
Formulary & Benefit (F&B) or NCPDP RTPB standards could be used.
(2) Transactions
    As of the date this proposed rule appears in the Federal Register, 
providers can use the NCPDP SCRIPT standard versions 2017071 and 
2023011 for multiple transactions associated with the electronic prior 
authorization of drugs covered under a pharmacy benefit. The SCRIPT 
standard can be used in conjunction with the NCPDP F&B or NCPDP RTPB 
standards, to support a complete workflow around determining whether 
prior authorization is required. Additionally, these versions of the 
NCPDP SCRIPT standard include transactions for requesting prior 
authorization for drugs, communicating decisions, and exchanging 
information regarding appeals. The NCPDP SCRIPT standard version 
2023011 has numerous updates from version 20217071, including that it 
can facilitate a three-way transaction to notify providers and 
pharmacies when prior authorization has been requested.28 29 
The NCPDP SCRIPT standard versions 2017071 and 2023011 support both the 
workflow to determine whether prior authorization is required and the 
coverage and documentation requirements to receive a decision, as well 
as the technical processes to send prior authorization requests from a 
provider to a payer, followed by the payer's responses (for example, 
approved, denied, and additional information required). The NCPDP 
SCRIPT standard versions 2017071 and 2023011 also support features that 
minimize manual data entry by the provider based on information in the 
EHR or other health IT system. These functions should reduce the time a 
provider or their administrative staff spend reviewing and responding 
to payer documentation requirements for prior authorization decisions. 
The NCPDP SCRIPT standard versions 2017071 and 2023011 can send 
information to a payer (or the payer's PBM) in real time, which should 
result in faster prior authorization approvals and therefore faster 
patient access to medications compared to manual prior authorization 
processes. We note that the NCPDP SCRIPT standard version 2017071 
expires on January 1, 2028, which is shortly after the proposed 
compliance date for certain impacted payers to support an unexpired 
version of the NCPDP SCRIPT standard adopted in 45 CFR 170.205(b). If 
our proposal is finalized, we would expect those impacted payers to 
utilize only the NCPDP SCRIPT standard versions 2023011 after January 
1, 2028 to meet the proposed requirements.

    Therefore, we are proposing to require that state Medicaid and CHIP 
FFS programs, Medicaid managed care plans, CHIP managed care entities, 
and QHP issuers on the FFEs support an unexpired version of the NCPDP 
SCRIPT standard adopted by the Secretary in 45 CFR 170.205(b) for the 
following transactions to support electronic prior authorization of 
drugs covered under a pharmacy benefit:

[[Page 19903]]

[GRAPHIC] [TIFF OMITTED] TP14AP26.273

    We emphasize that our proposals in this rule would not impose 
requirements directly on providers. We are not proposing to require 
providers to use the NCPDP SCRIPT standards or to conduct electronic 
prior authorization, but we acknowledge other HHS programs aim to 
support providers' ability to conduct electronic prior authorization 
using the NCPDP SCRIPT standard.
    The ``Health Data, Technology, and Interoperability: Patient 
Engagement, Information Sharing, and Public Health Interoperability: 
Electronic Prescribing, Real-Time Prescription Benefit and Electronic 
Prior Authorization'' final rule (hereinafter referred to as the ``HTI-
4 final rule'') (90 FR 36536) appeared in the Federal Register as part 
of the ``Medicare Program; Hospital Inpatient Prospective Payment 
Systems for Acute Care Hospitals (IPPS) and the Long-Term Care Hospital 
Prospective Payment System and Policy Changes and Fiscal Year (FY) 2026 
Rates; Changes to the FY 2025 IPPS Rates Due to Court Decision; 
Requirements for Quality Programs; and Other Policy Changes; Health 
Data, Technology, and Interoperability: Electronic Prescribing, Real-
Time Prescription Benefit and Electronic Prior Authorization'' final 
rule (hereinafter collectively referred to as the ``FY 2026 IPPS/LTCH 
final rule'') (90 FR 36536), which appeared in the Federal Register on 
August 4, 2025. In the HTI-4 final rule, ONC finalized that Health IT 
Modules certified under the ONC Health IT Certification Program to 45 
CFR 170.315(b)(3) are permitted to maintain conformance with either 
version 2017071 or version 2023011 of the NCPDP SCRIPT standard up to 
and including December 31, 2027. On and after January 1, 2028, all 
Health IT Modules certified to 45 CFR 170.315(b)(3) are required to 
support the NCPDP SCRIPT standard version 2023011. ONC also finalized 
that Health IT Modules seeking certification to the updated 
``electronic prescribing'' health IT certification criterion in 45 CFR 
170.315(b)(3) using the NCPDP SCRIPT standard version 2023011 must 
support certain electronic prior authorization transactions by January 
1, 2028 (90 FR 36541).
    Eligible hospitals and CAHs that participate in the Medicare 
Promoting Interoperability Program and MIPS eligible clinicians that 
participate in the MIPS Promoting Interoperability performance category 
must use certified EHR technology (42 CFR 495.4, 495.24(f)(1), and 
414.1375(b)(1)). As provided in 42 CFR 414.1305 and 42 CFR 495.4, we 
define certified EHR technology (CEHRT) for these programs as EHR 
technology that has been certified under the ONC Health IT 
Certification Program to meet the 2015 Edition Base EHR definition or 
subsequent Base EHR definition \30\ and

[[Page 19904]]

has been certified to certain ONC health IT certification criteria, 
adopted in 45 CFR 170.315, as necessary to report on objectives and 
measures in the Medicare Promoting Interoperability Program and the 
MIPS Promoting Interoperability performance category. To complete the 
measures under the Electronic Prescribing objectives in those programs, 
eligible hospitals, CAHs, and MIPS eligible clinicians must use CEHRT 
certified to the ``electronic prescribing'' criterion in 45 CFR 
170.315(b)(3).\31\ Once their Health IT Module is certified to the 
``electronic prescribing'' criterion finalized in the HTI-4 final rule, 
to complete the relevant measure requirements, participants in these 
programs are required to meaningfully use certified health IT capable 
of electronic prior authorization for prescription drugs using the 
NCPDP SCRIPT standard version 2023011 by January 1, 2028.
---------------------------------------------------------------------------

    \30\ Base EHR means an electronic record of health-related 
information on an individual that (1) Includes patient demographic 
and clinical health information, such as medical history and problem 
lists; (2) Has the capacity to provide clinical decision support; 
support physician order entry; capture and query information 
relevant to healthcare quality; exchange electronic health 
information with, and integrate such information from other sources; 
and (3) Has been certified to the certification criteria adopted by

and including December 31, 2024; section 170.315(b)(11) on and after 
January 1, 2025; section 170.315(b)(4) on and after January 1, 2028 
(see 45 CFR 170.102).
    \31\ For eligible hospitals and CAHs, see the FY 2026 IPPS/LTCH 
final rule (89 FR 69615); for MIPS eligible clinicians, see the CY 
2025 Medicare Physician Fee Schedule final rule (89 FR 98417-98427).
---------------------------------------------------------------------------

    We believe that providers would embrace electronic prior 
authorization using the NCPDP SCRIPT standard, as electronic prior 
authorization is less burdensome than manual prior authorization, as 
commenters told CMS in response to the 2022 CMS Interoperability and 
Prior Authorization proposed rule (89 FR 8765). In section II.C.4. of 
this proposed rule, we propose to require impacted payers to conduct 
electronic prior authorization using the NCPDP SCRIPT standard, which 
supports CMS's interoperability goals by reducing burden on providers 
and impacted payers. Requiring impacted payers to support the NCPDP 
SCRIPT standard also aligns with requirements for Medicare Part D 
prescribers, dispensers, and Part D sponsors, as finalized in the 2024 
Part D and Health IT Standards final rule (89 FR 51238) and previous 
rulemaking, and enables other payers and providers to benefit from 
consistent standards.
b. NCPDP Formulary & Benefit Standard
    The NCPDP F&B standard complements standards utilized for 
electronic prescribing, electronic prior authorization, and real-time 
prescription benefit applications, including the NCPDP SCRIPT standard, 
by providing formulary and benefit information at the health plan 
level. As discussed in section II.B. in this proposed rule, we are 
proposing to require impacted payers to support an unexpired version of 
the NCPDP F&B standard adopted by the Secretary in 45 CFR 170.205(u), 
for providers to use in their prior authorization workflow for drugs 
covered under a pharmacy benefit. In the 2024 Part D and Health IT 
Standards final rule, the Secretary adopted the NCPDP F&B standard 
version 60 in 45 CFR 170.205(u)(1) (89 FR 51260). This is the most 
recently published and adopted version of the standard as of the date 
this proposed rule appears in the Federal Register. Accordingly, if ONC 
establishes an expiration date for the NCPDP F&B standard or for a 
specific version thereof, upon the specified expiration date, impacted 
payers would no longer be permitted to use that standard or version to 
meet the interoperability requirements, and would be required to use 
another unexpired version adopted by the Secretary in 45 CFR 
170.205(u). We are proposing an October 1, 2027 compliance date for 
this proposed requirement.
    If this proposal is finalized, impacted payers could use an 
unexpired version of the NCPDP F&B standard adopted by the Secretary to 
provide a range of formulary and benefit information, such as formulary 
status, preferred alternatives, benefit coverage, and estimated co-pay 
information to end users, including providers, at the time of 
prescribing. This formulary and benefit information enables providers 
to determine at the point of prescribing whether a particular drug is 
covered and whether the impacted payer requires prior authorization. 
The information can then be used to create and send an electronic prior 
authorization request, using the NCPDP SCRIPT standard, to the payer or 
PBM, as appropriate.
    The NCPDP F&B standard relies on payers producing a periodic flat 
file (or simple, plain text database) that includes point-in-time 
information about drugs covered under a pharmacy benefit.\32\ The NCPDP 
F&B standard is mature and has widespread industry adoption to provide 
useful information about group-level drug coverage for a variety of use 
cases. However, the NCPDP F&B standard does not require this 
information to be updated in real time; therefore, as information 
changes, a payer's F&B file could become out of date. Furthermore, 
information is provided for group-level coverage information rather 
than being patient-specific.

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

c. NCPDP Real-Time Prescription Benefit Standard
    The NCPDP RTPB standard enables the real-time exchange of patient-
specific eligibility, drug coverage (including any restrictions and 
alternatives), and estimated cost sharing to enable access to this 
information at the point of prescribing. In the 2024 Part D and Health 
IT Standards final rule, the Secretary adopted the NCPDP RTPB standard 
version 13 in 45 CFR 170.205(c)(1) (89 FR 51260). This is the most 
recently published and adopted version of the standard as of the date 
this proposed rule appeared in the Federal Register.
    As discussed in section II.B.6. of this proposed rule, we are 
proposing to require impacted payers to support an unexpired version of 
the NCPDP RTPB standard adopted by the Secretary in 45 CFR 170.205(c). 
Accordingly, if ONC establishes an expiration date for the NCPDP RTPB 
standard or for a specific version thereof, upon the specified 
expiration date, impacted payers would no longer be permitted to use 
that standard or version to meet the interoperability requirements, and 
would be required to use another unexpired version adopted by the 
Secretary in 45 CFR 170.205(c). We are proposing an October 1, 2027 
compliance date for this proposed requirement.
    While the NCPDP F&B standard provides group-level coverage 
information to the provider, the NCPDP RTPB standard provides member-
specific information to the provider. The NCPDP F&B and NCPDP RTPB 
standards can complement each other in the provider's workflow to allow 
for relevant formulary, coverage, cost, and prior authorization 
information to be utilized when prescribing a drug. Findings from NCPDP 
grant-funded research on the NCPDP F&B and NCPDP RTPB standards showed 
that when the NCPDP F&B standard is used in conjunction with the NCPDP 
RTPB standard, providers had a more complete view of patient-specific 
medication options, costs, and prior authorization information at the 
point of prescribing.\33\

    Utilizing the proposed NCPDP standards for electronic prior 
authorization in the provider's workflow would likely lead to faster 
prior authorization processes and thus result in improved patient 
access to prescribed medications.
    In summary, we request comment on our proposals in the CFR 
citations listed in Table 2, and specifically on the following:
     The proposal to require state Medicaid and CHIP FFS 
programs, Medicaid managed care plans, CHIP managed care entities, and 
QHP issuers on the FFEs to support an unexpired version of the NCPDP 
SCRIPT standard adopted by the Secretary in 45 CFR 170.205(b) for the 
electronic prior authorization of drugs covered under a pharmacy 
benefit.
     The proposal to require state Medicaid and CHIP FFS 
programs, Medicaid managed care plans, CHIP managed care entities, and 
QHP issuers on the FFEs to support an unexpired version of the NCPDP 
F&B standard adopted by the Secretary in 45 CFR 170.205(u) to make 
available formulary and benefits information for drugs covered under a 
pharmacy benefit.
     The proposal to require state Medicaid and CHIP FFS 
programs, Medicaid managed care plans, CHIP managed care entities, and 
QHP issuers on the FFEs to support an unexpired version of the NCPDP 
RTPB standard adopted by the Secretary in 45 CFR 170.205(c) for 
exchanging real-time coverage information regarding drugs covered under 
a pharmacy benefit.
     The proposed October 1, 2027 compliance date for these 
proposals, as discussed in section II.B.2.c. of this proposed rule.
    In addition, we request comments on the following:
     Through what mechanisms do payers make their NCPDP F&B 
files available today?
     How frequently do payers or their PBMs update their F&B 
flat file today? How often should payers update their F&B flat file to 
account for formulary or benefit changes?
     How often do payers update the indicators for whether 
prior authorization is required within their F&B flat files? How often 
does that information change and is there typically a lag between 
policy changes and published F&B flat files?
     How frequently do providers use the NCPDP F&B standard as 
part of their prior authorization workflow today?
     How well integrated is the NCPDP F&B standard into 
providers' EHRs today?
     How accurate is the group-level information included in 
the NCPDP F&B standard to specific patients?
     How could impacted payers utilize the NCPDP RTPB standard 
to indicate whether a drug is covered under a medical benefit?
     Through what mechanisms do payers make information 
available using the NCPDP RTPB standard today?
     How frequently do providers use tools conforming to the 
NCPDP RTPB standard as part of their prior authorization workflow 
today?
     How prevalent is implementation of the NCPDP RTPB standard 
into providers' EHRs today? How automated are current interactions with 
the NCPDP RTPB standard within providers' EHRs and clinical workflow?
     For electronic prior authorization, would or could 
requiring impacted payers to make available information using the NCPDP 
RTPB standard negate the need for impacted payers to make available 
information using the NCPDP F&B standard? Does the NCPDP RTPB standard 
include all the necessary formulary and benefits information and 
functionality that would be available by using the NCPDP F&B standard 
for electronic prior authorization?
     Would requiring impacted payers to make information 
available using both standards add value, or create additional burden, 
specifically related to electronic prior authorization of drugs?
     Does the CRD IG have the technical capability to return 
specific coverage information through the ``CoverageInformation'' 
extension?
    ++ How could the ``CoverageInformation'' extension be best utilized 
to indicate whether a particular drug is covered under a medical 
benefit and whether the Prior Authorization API should be used for 
electronic prior authorization?
     Are there other existing technical solutions or methods 
that impacted payers could utilize to indicate to providers how a prior 
authorization request for a drug should be submitted?
3. Required Standards for FHIR APIs
a. Modification to Required Standards for FHIR APIs
    We are proposing to require each impacted payer to implement and 
maintain APIs that are conformant with applicable standards in 45 CFR 
170.215 in a manner that will allow for progressive adoption of new 
versions of these required standards. Under this approach, impacted 
payers would be permitted to conform with any updated versions of the 
required standards as the Secretary adopts them, via notice and comment 
rulemaking, in 45 CFR 170.215. In addition, if ONC establishes an 
expiration date for a standard in 45 CFR 170.215, or for a specific 
version thereof, upon the specified expiration date, impacted payers 
would no longer be permitted to use that standard or version to meet 
the interoperability requirements. When more than one unexpired version 
of a required standard is adopted in 45 CFR 170.215, impacted payers 
would be able to use any of the unexpired versions of the adopted 
standard to meet the interoperability requirements. This would allow 
impacted payers to have more predictable transition periods to update 
their APIs, and to conform with newer versions of the required 
standards in 45 CFR 170.215 as they are adopted, and older versions 
expire. CMS and ONC will work in close collaboration to evaluate the 
standards adopted in 45 CFR 170.215 and determine whether and when 
updated versions are ready for adoption through rulemaking.
    For example, in the 2024 CMS Interoperability and Prior 
Authorization final rule, we required impacted payers to use API 
technology conformant with the SMART App Launch IG, Release 1.0.0, in 
45 CFR 170.215(c)(1) (89 FR 8927-8928). In this proposed rule, we are 
proposing to revise this requirement so that impacted payers would be 
required to use API technology conformant with an unexpired version of 
the SMART App Launch IG adopted by the Secretary in 45 CFR 170.215(c). 
As of the date this proposed rule appears in the Federal Register, 
adopted versions of this standard include: (1) the SMART App Launch IG, 
Release 1.0.0 in 45 CFR 170.215(c)(1), which expired on January 1, 
2026, and (2) the SMART App Launch IG, Release 2.0.0 in 45 CFR 
170.215(c)(2), without an expiration date. In this example, impacted 
payers would need their API technology to be conformant with SMART App 
Launch IG, Release 2.0.0, as that would be the only unexpired version 
available upon the effective date of a final rule. Finalizing this 
proposal, which would require impacted payers to use an unexpired 
version of the required standards cross-referenced in 45 CFR 170.215, 
would revise the existing requirement that impacted payers use specific 
versions of these standards that have since expired.
    We propose to update the technical requirements for each API, for 
each impacted payer, to cross reference to

[[Page 19906]]

locations in 45 CFR 170.215 that include all versions of the required 
standards adopted by the Secretary. For readability purposes, citations 
where we are proposing to require the standards and IGs in 45 CFR 
170.215 for each impacted payer are listed in Table 2. Specifically, we 
propose to update the cross references to the following:
     HL7 FHIR Standard in 45 CFR 170.215(a);
     US Core IG in 45 CFR 170.215(b)(1);
     SMART App Launch IG in 45 CFR 170.215(c);
     Bulk Data Access IG in 45 CFR 170.215(d); and
     OpenID Connect Core in 45 CFR 170.215(e).
    We propose that the revised references to 45 CFR 170.215(a), 
(b)(1), and (c) through (e), as listed in Table 3, would be effective 
beginning on the effective date of the final rule, for all 
interoperability APIs.
    Impacted payers would continue to be required to maintain the 
Patient Access and Provider Directory APIs that they are presently 
required to maintain. In the 2024 CMS Interoperability and Prior 
Authorization final rule, we finalized requirements for impacted payers 
to make the Provider Access, Payer-to-Payer, and Prior Authorization 
APIs available beginning in 2027 (by January 1, 2027, for MA 
organizations and state Medicaid and CHIP FFS programs; by the first 
rating period beginning on or after January 1, 2027, for Medicaid 
managed care plans and CHIP managed care entities; and for plan years 
beginning on or after January 1, 2027, for individual market QHP 
issuers on the FFEs) (89 FR 8759-8760). This proposal would not change 
those compliance dates but would allow impacted payers to better plan 
for implementation by those dates as the Secretary adopts new standards 
or specifies new expiration dates for existing standards, or specific 
versions thereof, adopted in 45 CFR 170.215.
    As discussed in section II.A.1. of this proposed rule, ONC has 
adopted additional versions of certain required standards, which are 
included in Table 2. We also expect that several of the standards and 
IGs we currently require, or recommend and are proposing to require, 
may have newer versions published before this rule is finalized. For 
example, we expect that some of the IGs discussed in this proposed rule 
will be updated to support newer versions of the US Core IG. In this 
proposed rule, we discuss either the most recently published or most 
recently adopted versions of the standards and IGs at the time this 
proposed rule appears in the Federal Register.
    In summary, we request comment on our proposals in the CFR 
citations listed in Table 2, and specifically on the following:
     The proposal to require impacted payers to implement and 
maintain API technology conformant with unexpired versions of the 
standards adopted by the Secretary in 45 CFR 170.215, specifically 45 
CFR 170.215(a), (b)(1), and (c), (d), and (e), as applicable.
     The proposal to become effective beginning on the 
effective date of the final rule.
    In addition, we request comments on the following:
     Whether there are opportunities to streamline our 
regulatory requirements in instances where requiring conformance with 
the previously recommended IGs proposed in II.A.4.b. of this proposed 
rule for specific API use cases would achieve the same functional goal 
as explicitly requiring conformance with both the use-case specific IGs 
and required IGs or standards. For instance, whether it is necessary to 
require the base FHIR standard as well as the CRD, DTR, and PAS IGs 
that we propose to require for the Prior Authorization API, or whether 
requiring the CRD, DTR, and PAS IGs alone, which are based on the FHIR 
standard, would provide comparable technical guidance for implementers 
while reducing regulatory complexity.
    + Scenarios in which independently requiring both the required 
standards in this section (II.A.3.a. of the proposed rule) and use-case 
specific IGs proposed in section II.A.4.b. of the proposed rule could 
introduce alignment challenges. For instance, where one required 
standard references a specific version of another required standard, 
independent adoption of the latter standard could present further 
alignment challenges.
    + Instances in which requiring conformance with both the required 
standards in this section (II.A.3.a. of this proposed rule) and the 
use-case specific IGs proposed in section II.A.4.b. of the proposed 
rule are necessary to fully represent necessary technical requirements 
and should be maintained.
     Comments on whether it would be helpful to payers to more 
specifically identify capabilities of required IGs relevant to a 
specific API, to further streamline requirements and reduce unnecessary 
development. For instance, whether we should specify only those 
capabilities of the SMART App Launch IG relevant to the Patient Access 
API use case (e.g. the ``Patient Access for Standalone Apps'' 
Capability Set as well as the capabilities of ``launch-standalone'' and 
``context-standalone-patient,'' and the capabilities in subsections 
``Authorization Methods,'' ``Client Types,'' ``Single Sign-on,'' and 
``Permissions'' except the ``permission-online'' and ``permission-
user'').
4. Requiring Additional Implementation Guides to Support 
Interoperability APIs
a. Description of the Implementation Guides
    Using standards and IGs supports consistent implementation across 
the industry, thus leading to interoperable data exchange. There are 
many FHIR IGs that exist to support data exchange between payers, 
providers, and patients and enable the exchange of data such as claims, 
encounter, clinical, and coverage information; drug formulary 
information; and prior authorization information.
    Here, we provide descriptions of FHIR IGs that we require or 
recommend impacted payers support (89 FR 8927 and 8928, 8937, and 
8945). Specifically, we required impacted payers to use the Bulk Data 
Access IG for the Provider Access and Payer-to-Payer APIs, while the 
other IGs described later in this section were recommended.\34\ We are 
now proposing to require impacted payers to support these IGs as 
described in section II.A.4.b. of this proposed rule. Table 2 outlines 
the citations to where we propose to require use of the standards for 
each of the specified APIs.

(1) CARIN Implementation Guide for Blue Button[supreg]
    The Creating Access to Real-time Information Now through Consumer 
Directed Exchange (CARIN) Alliance designed the HL7 FHIR CARIN Consumer 
Directed Payer Data Exchange (CARIN IG for Blue Button) IG \35\ to meet 
the requirements in the 2020 CMS Interoperability and Patient Access 
final rule for impacted payers to make available adjudicated claims and 
encounter data, from a financial perspective, via a Patient Access API 
through consumer-directed exchange (85 FR 25532). Consumer-directed 
exchange occurs when a patient or an authorized personal representative 
requests the patient's digital health information via a health app or 
other third-party data steward, such as a health information exchange 
(HIE). As of the date this proposed rule appears in the Federal 
Register, the most recently published version is the CARIN IG for Blue 
Button, Version 2.2.0--STU 2.2.

(2) HL7 FHIR Da Vinci PDex Implementation Guide
    The HL7 FHIR Da Vinci Payer Data Exchange (PDex) IG \36\ 
facilitates the creation and exchange of a patient's health history 
using clinical data (based on US Core Profiles established from FHIR 
R4) in a manner that allows providers to integrate the data received 
into their EHRs. The PDex IG supports sharing of payer data through a 
more clinical perspective, in line with the United States Core Data for 
Interoperability (USCDI) and US Core IG, than a financial perspective 
as is done with the CARIN IG for Blue Button. However, the PDex IG does 
include information about prior authorizations that impacted payers are 
required to make available by the 2024 CMS Interoperability and Prior 
Authorization final rule (89 FR 8758). The PDex IG can support all the 
required data elements for prior authorization data exchange, though we 
note that the PDex IG enhancements to support payer to payer bulk data 
exchange, payer to provider exchange, and explanation of benefits are 
currently in draft form and have not appeared in ballot, but have been 
tested at multiple Connectathons. The PDex IG has been updated to 
support newer versions of the US Core IG, including versions 6.1.0 and 
7.0.0. As of the date this proposed rule appears in the Federal 
Register, the most recently published and adopted version is the PDex 
IG, Version 2.1.0--STU 2.1.

(3) HL7 FHIR Da Vinci PDex US Drug Formulary Implementation Guide
    The HL7 FHIR Da Vinci PDex US Drug Formulary IG (PDex US Drug 
Formulary IG) \37\ defines a FHIR interface to a payer's drug formulary 
information for patients. A drug formulary is a list of prescription 
drugs covered by the payer under the patient's coverage. The primary 
use case for this FHIR interface is to enable patients to understand 
the costs for drugs that have been prescribed and to compare their drug 
costs across different types of coverage. As of the date this proposed 
rule appears in the Federal Register, the most recently published 
version is the PDex US Drug Formulary IG, Version 2.1.0--STU 2.

(4) HL7 FHIR Da Vinci PDex Plan Net Implementation Guide
    The HL7 FHIR Da Vinci PDex Plan Net IG (PDex Plan Net IG) \38\ 
defines a FHIR interface to access information about a payer's health 
plans, associated networks, and the providers and other entities that 
participate in their networks. Publishing that information through a 
publicly available FHIR API allows third party developers to build apps 
for patients to find in-network care that could be covered by their 
payer. As of the date this proposed rule appears in the Federal 
Register, the most recently published version is the PDex Plan Net IG, 
Version 1.2.0--STU 1.2 US.

5) FHIR Bulk Data Access Implementation Guide
    The FHIR Bulk Data Access (Flat FHIR) IG (Bulk Data Access IG) \39\ 
was developed to facilitate the exchange of a large number of patient 
records at the same time. FHIR APIs generally work well for accessing 
small amounts of data, but large data exports can require hundreds or 
thousands of requests that may overwhelm a FHIR server. This IG defines 
a standardized, FHIR-based approach for asynchronously exporting bulk 
data from a FHIR server to an authorized client. As of the date this 
proposed rule appears in the Federal Register, the most recently 
published version is the Bulk Data Access IG (v3.0.0: STU 3).

(6) HL7 FHIR Da Vinci CRD, DTR, and PAS Implementation Guides
    These three IGs are designed to be used by payers to develop and 
implement the Prior Authorization API. The HL7 FHIR Da Vinci Coverage 
Requirements Discovery (CRD) IG \40\ defines a workflow to allow payers 
to provide information about coverage requirements to providers through 
their EHR or other health IT system. This is the first stage of the 
process for determining whether prior authorization is required for 
certain items or services. The CRD IG enables the Prior Authorization 
API to inform a provider whether prior authorization is required and 
provide information about the payers' prior authorization coverage 
rules, so the provider knows what is necessary to support prior 
authorization approval. As of the date this proposed rule appears in 
the Federal Register, the most recently published version is the CRD 
IG, Version 2.2.1--STU 2.2.\41\

    The HL7 FHIR Da Vinci Documentation Templates and Rules (DTR) IG 
\42\ specifies how payer documentation requirements for prior 
authorization requests can be communicated to a provider. If necessary, 
this would allow providers to download questionnaires and populate them 
automatically with information from their EHR or other health IT 
systems to demonstrate medical necessity or other coverage requirements 
based on the payer's specific rules. The DTR IG can also automate the 
assemblage of documentation to support a prior authorization request. 
For instance, the DTR IG can be used to write rules that support 
automatically extracting patient information from the EHR or other 
health IT system for the provider to review and confirm before 
submission. As of the date this proposed rule appears in the Federal 
Register, the most recently published version is the DTR IG, Version 
2.2.0--STU 2.2.\43\

    The HL7 FHIR Da Vinci Prior Authorization Support (PAS) IG \44\ 
enables prior authorization requests and decisions to be transmitted 
via FHIR API from within providers' EHRs or other health IT systems. 
The PAS IG is the basis for: (1) assembling the information necessary 
to substantiate the clinical need for a particular treatment; and (2) 
submitting the assembled information and prior authorization request to 
the intended recipient. The PAS IG also defines capabilities for 
managing prior authorization requests, including checking the status of 
a previously submitted request, updating a previously submitted 
request, and canceling a request. As of the date this proposed rule 
appears in the Federal Register, the most recently published

b. Requiring Implementation Guides
    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we discussed use-case specific IGs that impacted payers can use 
to implement their interoperability APIs (89 FR 8937). Using those IGs 
supports interoperability because impacted payers need not develop an 
approach independently, which should save time and resources. In that 
final rule, we strongly encouraged payers to use the IGs listed as 
``recommended'' in Table H3 for each API, in addition to the required 
standards in 45 CFR 170.215 (89 FR 8945). We recommended specific IGs 
for each API to provide guidance to the industry without locking payers 
into the versions of those IGs available at the time of the 2022 CMS 
Interoperability and Prior Authorization proposed rule (89 FR 8937). We 
carefully considered the versions of the recommended IGs that were 
available at the time and determined that they were not ready to be 
proposed as requirements. However, we acknowledged that by recommending 
rather than requiring certain IGs, there is potential for 
implementation variation that could limit interoperability and 
ultimately lead to rework for impacted payers if we required the IGs in 
the future (89 FR 8937). We believed that those IGs would continue to 
be refined as they were tested and implemented in the real world. We 
stated that we would continue to monitor and evaluate the IGs' 
development and consider whether to propose to require their use in the 
future (89 FR 8937). Since publication of the 2022 CMS Interoperability 
and Prior Authorization proposed rule, those IGs have continued to 
mature, and updated versions of many of the recommended IGs have been 
published.
    Therefore, we are now proposing to require impacted payers to 
implement and maintain API technology conformant with specific IGs for 
each applicable API. We propose to require these IGs to through cross 
references to the applicable citations in 45 CFR 170.215. For 
readability purposes, citations where we propose to require the IGs for 
each type of impacted payer are listed in Table 2.
    In the HTI-4 final rule, the Secretary adopted the following IGs 
(90 FR 37167 and 37182):
     CARIN IG for Blue Button, Version 2.0.0--STU 2 in 45 CFR 
170.215(k)(1)(i);
     PDex IG, Version 2.1.0--STU 2.1 in 45 CFR 
170.215(k)(2)(i);
     PDex US Drug Formulary IG, Version 2.0.1--STU 2 in 45 CFR 
170.215(m)(1);
     PDex Plan Net IG, Version 1.1.0--STU 1.1 US in 45 CFR 
170.215(n)(1);
     CRD IG, Version 2.0.1--STU 2 in 45 CFR 170.215(j)(1);
     DTR IG, Version 2.0.1--STU 2 in 45 CFR 170.215(j)(2)(i); 
and
     PAS IG, Version 2.0.1--STU 2 in 45 CFR 170.215(j)(3)(i).
    Since publication of the ``Health Data, Technology, and 
Interoperability: Patient Engagement, Information Sharing, and Public 
Health Interoperability'' proposed rule (89 FR 63498) (hereinafter 
referred to as the ``HTI-2 proposed rule''), which appeared in the 
Federal Register on August 5, 2024, and subsequent finalization of the 
HTI-4 final rule, updated versions of many of the standards and IGs 
have been published. In section II.J. of this proposed rule, ONC is now 
proposing to adopt updated versions of standards in 45 CFR 170.215 and 
proposing to add expiration dates to versions of these standards that 
were previously adopted in 45 CFR 170.215. We propose to cross 
reference the locations in 45 CFR 170.215 that include those versions 
of a specific standard adopted by the Secretary, and specify that 
impacted payers must use an unexpired version of the standard at that 
location:
     CARIN IG for Blue Button in 45 CFR 170.215(k)(1);
     PDex IG in 45 CFR 170.215(k)(2);
     PDex US Drug Formulary IG in 45 CFR 170.215(m)(1);
     PDex Plan Net IG in 45 CFR 170.215(n)(1);
     CRD IG in 45 CFR 170.215(j)(1);
     DTR IG in 45 CFR 170.215(j)(2); and
     PAS IG in 45 CFR 170.215(j)(3).
    Requiring impacted payers to use an unexpired version of the 
standards adopted in 45 CFR 170.215 automatically incorporates updated 
versions into the interoperability requirements as they are adopted by 
the Secretary. Specifically, if the Secretary adopts updated versions 
of any of these standards, such as the updated versions ONC has 
proposed for adoption in section II.J. of this proposed rule (subject 
to finalization), those versions would be incorporated in 45 CFR 
170.215. As noted previously, if the Secretary establishes an 
expiration date for a standard, or for specific version thereof, upon 
the specified expiration date, impacted payers would no longer be 
permitted to use that standard or version to meet the interoperability 
requirements.
    We propose that impacted payers would be required to implement and 
maintain API technology conformant with an unexpired version of the 
proposed additional FHIR IGs for each API as described in section 
II.A.4.b. of this proposed rule beginning on October 1, 2027. In the 
2024 CMS Interoperability and Prior Authorization final rule, we 
finalized compliance dates beginning in 2027 for impacted payers to 
implement and maintain Provider Access, Payer-to-Payer, and Prior 
Authorization APIs (89 FR 8790, 8820, and 8860). We recognize that 
impacted payers may already be developing and implementing their APIs 
to comply with the technical requirements established in the 2024 CMS 
Interoperability and Prior Authorization final rule in preparation for 
the January 1, 2027 compliance deadline. Some impacted payers may have 
opted not to use the currently recommended IGs, which we now propose to 
require. Therefore, we believe that the proposed October 1, 2027 
compliance date would provide impacted payers with additional time to 
update their APIs to conform to the additional IGs we are proposing to 
require beginning on October 1, 2027. Table 3 in this proposed rule 
lists the required standards finalized in the 2024 CMS Interoperability 
and Prior Authorization final rule and additional FHIR IGs proposed in 
this rule by applicable API.
(1) Patient Access API
    In the 2020 CMS Interoperability and Patient Access final rule, we 
required impacted payers to implement and maintain a standards-based 
Patient Access API (85 FR 25558).\46\ The Patient Access API allows 
patients, through the health apps of their choice, to easily access 
their claims and encounter information, including provider remittances 
and patient cost-sharing, as well as all data classes and data elements 
included in a content standard (USCDI) adopted by the Secretary in 45 
CFR 170.213.\47\ In the 2024 CMS

[[Page 19909]]

Interoperability and Prior Authorization final rule, we finalized a 
requirement that, beginning in 2027 (by January 1, 2027, for MA 
organizations and state Medicaid and CHIP FFS programs; by the rating 
period beginning on or after January 1, 2027, for Medicaid managed care 
plans and CHIP managed care entities; and for plan years beginning on 
or after January 1, 2027, for QHP issuers on the FFEs), impacted payers 
must include certain information about prior authorizations for non-
drug items and services in the data that are available through the 
Patient Access API (89 FR 8768).\48\ In that 2024 final rule, we also 
finalized a requirement that impacted payers must implement and 
maintain their Patient Access APIs conformant with standards in 45 CFR 
170.215, including FHIR, US Core IG, SMART App Launch IG, and the 
OpenID Connect Core 1.0.

care entities, and 45 CFR 156.221(b) for individual market QHP 
issuers.
---------------------------------------------------------------------------

    To further support consistent implementation of the Patient Access 
API, we are now proposing to require impacted payers to implement and 
maintain API technology conformant with an unexpired version of the 
CARIN IG for Blue Button, the PDex IG, and the PDex US Drug Formulary 
IG adopted by the Secretary. Specifically, we are proposing to require 
impacted payers to implement and maintain a Patient Access API 
conformant with the CARIN IG for Blue Button to support sharing claims 
and encounter data, the PDex IG to support sharing clinical data and 
prior authorization information, and the PDex US Drug Formulary IG to 
share a formulary of drugs covered by the payer under the patient's 
health plan through the Patient Access API. We believe that by 
requiring these IGs, impacted payers would format data available 
through the Patient Access API in a consistent manner that would allow 
health app developers to easily access and display patients' health 
data, thus having those data readily available and easily accessible to 
patients. Enabling patients to easily access their health information 
electronically through an API should allow patients to better manage 
their health care.
(2) Provider Access API
    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we finalized a requirement for impacted payers to implement and 
maintain a Provider Access API conformant with standards in 45 CFR 
170.215, including FHIR, US Core IG, SMART App Launch IG, and the Bulk 
Data Access IG (85 FR 25521-25522 and 89 FR 8788). Providers would be 
able to use that API to access current patient data from impacted 
payers, including adjudicated claims and encounter data (excluding 
provider remittances and patient cost-sharing information), all data 
classes and data elements included in a content standard (USCDI) in 45 
CFR 170.213, and certain information about prior authorizations for 
non-drug items and services.\49\
---------------------------------------------------------------------------

    \49\ See 42 CFR 422.121(a)(2) for MA organizations, 42 CFR 
431.61(a)(2) for state Medicaid FFS programs, 42 CFR 457.731(a)(2) 
for CHIP FFS programs, through cross reference to 42 CFR 431.61 in 
42 CFR 438.242(b)(7) for Medicaid managed care plans, through cross 
reference to 42 CFR 438.242 in 42 CFR 457.1233(d) for CHIP managed 
care entities, and 45 CFR 156.222(a)(2) for individual market QHP 
issuers.
---------------------------------------------------------------------------

    To facilitate care coordination and to further standardize impacted 
payers' APIs, we are now proposing to require impacted payers to 
implement and maintain API technology conformant with an unexpired 
version of the CARIN IG for Blue Button and the PDex IG adopted by the 
Secretary in their Provider Access API implementation. Specifically, we 
are proposing to require impacted payers to implement and maintain a 
Provider Access API conformant with the CARIN IG for Blue Button, to 
support sharing claims and encounter data, as well as the PDex IG, to 
support sharing clinical data and prior authorization information.
    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we finalized requirements for impacted payers to make drug 
formulary information available through the Provider Access API in 
alignment with the Patient Access API requirements set forth in the 
2020 CMS Interoperability and Patient Access final rule.\50\ We refer 
readers to section II.E.3. of this proposed rule, where we discuss our 
proposal to remove drug formulary information from the content required 
in the Provider Access and Payer-to-Payer APIs. However, we will 
consider the comments we receive on this proposal and may choose to 
retain this requirement, in which case we propose here, as an 
alternative, to require the PDex US Drug Formulary IG at the citations 
identified in Table 2 along with the other standards for the Provider 
Access API to support consistent solutions for sharing drug formulary 
information.

(3) Provider Directory API
    In the 2020 CMS Interoperability and Patient Access final rule, we 
finalized a requirement that impacted payers (excluding QHP issuers on 
the FFEs) must implement and maintain a Provider Directory API to make 
available specific information about their provider networks.\51\ 
Impacted payers were required to implement and maintain the Provider 
Directory API by January 1, 2021.\52\ To further standardize 
implementation, we are now proposing to require impacted payers to 
implement and maintain a Provider Directory API conformant with an 
unexpired version of the PDex Plan Net IG adopted by the Secretary. The 
PDex Plan Net IG defines the technical parameters and data elements to 
share information about a payer's network and the providers and other 
entities that participate in their network.

cross reference to 42 CFR 438.242 in 42 CFR 457.1233(d) for CHIP 
managed care entities.
---------------------------------------------------------------------------

(4) Payer-to-Payer API
    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we finalized a requirement that, beginning in 2027 (by January 1, 
2027, for MA organizations and state Medicaid and CHIP FFS programs; by 
the rating period beginning on or after January 1, 2027, for Medicaid 
managed care plans and CHIP managed care entities; and for plan years 
beginning on or after January 1, 2027, for QHP issuers on the FFEs), 
impacted payers must implement and maintain a Payer-to-Payer API to 
exchange patient data when a patient moves between payers or has 
concurrent coverage to ensure continued access to their health data and 
support care continuity and coordination between payers.\53\ 
Specifically, this data

[[Page 19910]]

exchange requirement includes adjudicated claims and encounter data 
(excluding provider remittances and patient cost-sharing information), 
all data classes and data elements included in a content standard 
(USCDI) in 45 CFR 170.213, and certain information about prior 
authorizations for non-drug items and services.\54\

programs, through cross reference to 42 CFR 438.242 in 42 CFR

programs, 42 CFR 438.242 in 42 CFR 457.1233(d) for CHIP managed care 
entities, and 45 CFR 156.222(b)(4)(ii) for individual market QHPs.
---------------------------------------------------------------------------

    To ensure impacted payers are implementing the Payer-to-Payer API 
in an interoperable and standardized way, we are now proposing to 
require impacted payers to implement and maintain API technology 
conformant with the CARIN IG for Blue Button and the PDex IG. 
Specifically, we are proposing to require impacted payers to implement 
and maintain a Payer-to-Payer API conformant with an unexpired version 
of the CARIN IG for Blue Button adopted by the Secretary to support 
sharing claims and encounter data, as well as the PDex IG to support 
sharing clinical data and prior authorization information.
    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we require impacted payers to make drug formulary information 
available through the Payer-to-Payer API in alignment with the Patient 
Access API requirements set forth in the 2020 CMS Interoperability and 
Patient Access final rule.\55\ We refer readers to section II.E.3. of 
this proposed rule, where we discuss our proposal to remove drug 
formulary information from the content required in the Payer-to-Payer 
and Provider Access APIs. However, we will consider the comments we 
receive on this proposal and may choose to retain this requirement, in 
which case we propose here, as an alternative, to require the PDex US 
Drug Formulary IG at the citations identified in Table 2 along with the 
other standards for the Payer to Payer API to support consistent 
solutions for sharing drug formulary information.
---------------------------------------------------------------------------

    \55\ See cross reference to 42 CFR 422.119(b) in 42 CFR 
422.121(b)(4)(ii)(A) for MA organizations, through cross reference 
to 42 CFR 431.60(b) in 42 CFR 431.61(b)(4)(ii)(A) for state Medicaid 
FFS programs, through cross reference to 42 CFR 457.730(b) in 42 CFR 
457.731(b)(4)(ii)(A) for state CHIP FFS programs, through cross 
reference to 42 CFR 431.61 in 42 CFR 438.242(b)(7), and through 
cross reference to 42 CFR 438.242 in 42 CFR 457.1233(d).
---------------------------------------------------------------------------

(5) Prior Authorization API
    To streamline the prior authorization process, in the 2024 CMS 
Interoperability and Prior Authorization final rule, we finalized a 
requirement that impacted payers must implement and maintain a Prior 
Authorization API beginning in 2027 (by January 1, 2027, for MA 
organizations and state Medicaid and CHIP FFS programs; by the rating 
period beginning on or after January 1, 2027, for Medicaid managed care 
plans and CHIP managed care entities; and for plan years beginning on 
or after January 1, 2027, for QHP issuers on the FFEs).\56\ The Prior 
Authorization API would allow providers to determine whether a specific 
impacted payer requires prior authorization for a certain item or 
service, query the impacted payer's prior authorization documentation 
requirements, as well as facilitate the automated compilation of 
necessary information to submit a prior authorization request 
electronically (89 FR 8861).
---------------------------------------------------------------------------

    \56\ See 42 CFR 422.122(b) for MA organizations, 42 CFR 
431.80(b) for state Medicaid FFS programs, through cross reference 
to 42 CFR 431.80(b) in 42 CFR 438.242(b)(7) for Medicaid managed 
care plans, 42 CFR 457.732(b) for state CHIP FFS programs, through 
cross reference to 42 CFR 438.242 in 42 CFR 457.1233(d), and 45 CFR 
156.223(b) for individual market QHPs.
---------------------------------------------------------------------------

    At the time of the 2022 CMS Interoperability and Prior 
Authorization proposed rule, we did not believe that the CRD, DTR, and 
PAS IGs were mature enough to propose requiring impacted payers to use 
them, and therefore, we only recommended their use. In the final rule, 
we updated our recommendations to the latest versions of the CRD, DTR, 
and PAS IGs (89 FR 8937 and 8945). Upon reviewing updated versions of 
the CRD, DTR, and PAS IGs that have been published since the 2022 CMS 
Interoperability and Prior Authorization proposed rule appeared in the 
Federal Register, we now believe that these IGs are mature enough for 
us to propose to require their use. We believe that requiring impacted 
payers to use these three IGs in their Prior Authorization APIs would 
avoid inconsistent or proprietary solutions that would make it 
challenging for providers to easily connect with impacted payers. 
Therefore, to ensure uniform and consistent implementations of the 
Prior Authorization API, we are now proposing to require impacted 
payers to implement and maintain API technology conformant with an 
unexpired version of the CRD, DTR, and PAS IGs adopted by the Secretary 
to implement their required Prior Authorization API.
    Specifically, we are proposing to require impacted payers to 
implement and maintain a Prior Authorization API conformant with an 
unexpired version of the CRD IG adopted by the Secretary to define the 
technical implementation to allow providers to access coverage 
requirements through their EHR or other health IT system. The CRD IG 
allows providers to then discover specific payer requirements for what 
services are covered by the payer and whether prior authorization is 
required.\57\ We are also proposing to require impacted payers to 
implement and maintain a Prior Authorization API conformant with an 
unexpired version of the DTR IG adopted by the Secretary so providers 
can consistently access documentation requirements through their EHR or 
other health IT system, as well as to gather information needed to 
support prior authorization requests.\58\ Finally, we are proposing to 
require impacted payers to implement and maintain a Prior Authorization 
API conformant with an unexpired version of the PAS IG adopted by the 
Secretary to enable the direct submission of prior authorization 
requests from providers' health IT systems to the impacted payer.\59\

c. Using Testing Tools To Ensure Conformance With Implementation Guides
    The technical requirements for the APIs we finalized in the 2020 
CMS Interoperability and Patient Access and the 2024 CMS 
Interoperability and Prior Authorization final rules include general 
requirements for impacted payers to test their interoperability APIs 
(85 FR 25514 and 89 FR 8927).\60\ For instance, technical requirements 
for APIs established by MA plans in 42 CFR 422.119(c) state that payers 
must conduct routine testing and monitoring, and update as appropriate, 
to ensure the API functions properly. We are seeking to provide more 
information about the existing testing requirement to further advance 
interoperable data exchange across the health care system using 
standard APIs.
---------------------------------------------------------------------------

    \60\ For information on current regulatory requirements that are 
applicable to each impacted payer, see Table H1: Use of 
Interoperability Standards for Required APIs and Table H2: Use of 
Updated Standards for the Required APIs in the 2024 CMS 
Interoperability and Prior Authorization final rule (89 FR 8943 and 
8944). For information on the proposed regulatory requirements that 
would be applicable to each impacted payer, see Table 2: Proposed 
Updates to Required Standards for Interoperability APIs in section 
II.A.5. of this proposed rule.
---------------------------------------------------------------------------

    Testing tools are available that can help impacted payers to meet 
existing testing requirements for APIs, for instance, with ensuring 
conformance to specified standards. The Inferno testing tool on 
HealthIT.gov (hereinafter referred to as ``Inferno'') is an HL7 FHIR 
testing tool offered by ONC.\61\ Inferno is an open-source tool for 
creating, executing, and sharing conformance tests for numerous FHIR 
standards and IGs. ONC has developed test kits within Inferno that can 
be used by payers to test API conformance with certain versions of the 
required standards and proposed IGs.\62\ For example, Inferno test kits 
are currently published for the following specifications:

     PDex US Drug Formulary IG, Version 2.0.1--STU 2; and
     PDex Plan Net IG, Version 1.1.0--STU 1.1.
    Inferno uses a combination of automated and manual verification to 
assess a system's conformance. Inferno can act as a server to test an 
app by receiving requests, returning appropriate responses, and 
validating the conformance of the app's requests and its ability to 
handle the responses appropriately. Inferno can also test a server by 
acting as an app, making requests against the server and validating the 
conformance and appropriateness of the server's responses. We intend to 
work with ONC on additional and updated test kits for subsequently 
adopted versions of the IGs above, new versions of the IGs identified 
through the Standards Version Advancement Process (SVAP) that may be 
available for voluntary use by payers, and additional IGs identified to 
support payer APIs.
    CMS strongly encourages impacted payers to utilize available 
testing tools, such as the Inferno testing tool, to meet the existing 
testing requirements and ensure conformance with the required IGs. We 
also encourage impacted payers to publish testing results to 
demonstrate conformance with the technical requirements. Doing so would 
increase transparency and trust that the technology has been properly 
implemented to facilitate interoperability. Inferno can be downloaded 
for local deployment and is hosted on ONC's website at https://inferno.healthit.gov/.
    We also note that we include an RFI in section III.C. of this 
proposed rule soliciting public feedback on how we can continue to 
strengthen oversight mechanisms to ensure the required interoperability 
APIs are appropriately implemented.
d. Voluntary Use of Updated Versions of Required Standards
    As discussed in section II.A.1. of this proposed rule, we 
previously finalized policies that allow impacted payers to conform 
with updated versions of the required standards in 45 CFR 170.213 and 
45 CFR 170.215 under certain conditions. There are certain conditions 
that must be met for impacted payers to be permitted to use updated 
versions of the required standards, for example, the conditions 
described in 42 CFR 422.119(c) for MA plans. We emphasize two of those 
conditions here.
    First, we note that if impacted payers choose to use updated 
standards, it must not disrupt an end user's ability to access the 
required data as finalized in the 2020 CMS Interoperability and Patient 
Access and 2024 CMS Interoperability and Prior Authorization final 
rules (85 FR 25532 and 89 FR 8935). Another condition that permits 
impacted payers to voluntarily use an updated version of a required 
standard in 45 CFR 170.213 or 45 CFR 170.215 is when the National 
Coordinator has approved the updated version for use in the ONC Health 
IT Certification Program.\63\ The National Coordinator approves updated 
versions of standards for the ONC Health IT Certification Program 
through the Standards Version Advancement Process (SVAP), pursuant to 
45 CFR 170.555, as finalized in the ``21st Century Cures Act: 
Interoperability, Information Blocking, and the ONC Health IT 
Certification Program'' final rule (85 FR 25642) (hereinafter referred 
to as the ``ONC Cures Act final rule''), which appeared in the Federal 
Register on May 1, 2020, as a Maintenance of Certification flexibility 
included in the real-world testing Condition of Certification (85 FR 
25775). This flexibility permits health IT developers to voluntarily 
use, in certain certified Health IT Modules, newer versions of adopted 
standards if specific conditions are met, which allows the ONC Health 
IT Certification Program to keep pace with the industry's standards 
development efforts.
---------------------------------------------------------------------------

QHP issuers.
---------------------------------------------------------------------------

    Under SVAP, after a standard has been adopted through notice and 
comment rulemaking, ONC engages in an open and transparent process to 
timely ascertain whether an updated version of the adopted standard or 
implementation specification should be

[[Page 19912]]

approved by the National Coordinator for health IT developers' 
voluntary use in the ONC Health IT Certification Program. ONC publishes 
updated versions of standards under consideration for SVAP and lists 
the updated versions of standards that the National Coordinator has 
approved as part of the Interoperability Standards Advisory (ISA) on 
HealthIT.gov.\64\ Members of the public can use this resource to review 
standards that may be approved through SVAP in the future, as well as 
provide input on which updated versions should be approved. SVAP occurs 
annually, meaning that newer versions of standards will continue to be 
updated and assessed by ONC for use. Impacted payers may find it 
beneficial to monitor the SVAP process to stay current on standards 
updates and to assess whether adoption of a newer version of a standard 
may be an option. We encourage impacted payers to review these 
resources to better understand how updated versions of the standards in 
45 CFR 170.213 and 45 CFR 170.215 may be approved by the National 
Coordinator through SVAP and meet that condition for using an updated 
standard.

5. Recommended Implementation Guides To Support Interoperability APIs 
and Request for Comment
    As we have discussed, using common standards and IGs supports 
consistent implementations across the industry. However, as noted in 
the 2024 CMS Interoperability and Prior Authorization final rule, IGs 
take time to mature (89 FR 8839 through 8841). We believe it is 
important to recommend these additional IGs, although they may not be 
fully mature, to provide direction towards a common set of 
specifications. If we did not include these recommendations, it could 
lead to more implementation variation and cause a greater burden on 
implementers. We are now recommending additional IGs for certain 
interoperability APIs.
    For the Provider Access API we are recommending the HL7 FHIR Da 
Vinci Member Attribution (ATR) List IG (ATR List IG).\65\ The ATR List 
IG provides specific technical guidance for payers and providers to 
exchange Member Attribution Lists. The Member Attribution List 
typically contains information about plans/contracts, attributed 
patients, attributed providers, attributed organizations, and patient 
coverage and can be used by providers and payers to support use cases 
for quality reporting, payer data exchange, and clinical data exchange 
by identifying populations of patients that are relevant between data 
exchange partners. The ATR List IG allows transactions to exchange a 
full Member Attribution List, request changes to existing Member 
Attribution Lists, and request and receive notifications of changes to 
Member Attribution Lists. As of the date this proposed rule appears in 
the Federal Register, the most recently published version is the ATR 
List IG, Version 2.1.0--STU 2.1.
---------------------------------------------------------------------------

    \65\ Health Level Seven International. (n.d.). Da Vinci ATR List 
IG. Retrieved from http://hl7.org/fhir/us/davinci-atr/ImplementationGuide/hl7.fhir.us.davinci-atr.
---------------------------------------------------------------------------

    For the Provider Access API specifically, the ATR List IG can be 
used to identify members with an established patient treatment, 
contractual, or other type of relationship with providers, provider 
groups, and organizations to enable data exchange access. Impacted 
payers could also use the ATR List IG to identify groups of members 
that are opting out of sharing data with providers.
    For the Prior Authorization API, we are recommending the HL7 FHIR 
Da Vinci Clinical Data Exchange (CDex) IG.\66\ The CDex IG provides 
detailed guidance that helps implementers use FHIR-based interactions 
to support specific clinical data exchanges. In the context of the IG, 
``clinical data'' means any information a provider holds in a patient's 
health record. Unlike the PDex IG, the format of the data exchanged is 
not limited to FHIR resources but includes the ability to provide 
attachments such as HL7 Consolidated Clinical Document Architecture (C-
CDA) documents, Portable Document Formats (PDFs), text files, and other 
types of data. Using the CDex IG allows the standardized exchange of 
non-structured data, such as radiological images, questionnaires, or 
lab results, as attachments for a variety of purposes, including 
determining the medical necessity of a prior authorization request. As 
of the date this proposed rule appears in the Federal Register, the 
most recently published version is the CDex IG, Version 2.1.0--STU 2.1. 
The CDex IG describes how attachments to claims and prior 
authorizations transactions can be requested and sent to support payer 
operations. We are recommending the CDex IG specifically to support 
prior authorization exchanges but note that its capabilities go beyond 
that purpose and can be used in the other APIs.
---------------------------------------------------------------------------

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

    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we discussed different methods of authentication and 
authorization (89 FR 8841-8842). We recognized that while protocols 
involving specific user credentials managed by an impacted payer could 
be used for the Provider Access and Prior Authorization APIs, other 
protocols, such as SMART Backend Services, mutual Transport Layer 
Security (mTLS), Unified Data Access Profiles (UDAPTM), or 
other trust community-specified means to enable authentication, may be 
easier to implement at scale (89 FR 8942). Likewise, protocols 
requiring user level credentials, managed by the impacted payer, are 
generally not appropriate for business-to-business data exchanges like 
the Payer-to-Payer API where an individual may not be directly 
initiating the exchange.
    As discussed in the 2024 CMS Interoperability and Prior 
Authorization final rule, efforts have been made to further refine the 
specifications for security (including authentication) at scale through 
UDAP via the FHIR at Scale Taskforce (FAST) Security for Scalable 
Registration, Authentication, and Authorization IG (FAST Security IG) 
(89 FR 8802). We are recommending the FAST Security IG \67\ to support 
standardized dynamic registration, authentication, and authorization 
requirements for the Patient Access, Provider Access, Payer-to-Payer, 
and Prior Authorization APIs to provide a more uniform, standardized, 
and automated application registration pathway. The FAST Security IG 
enables scalable and standardized application registration capabilities 
compatible with FHIR and the SMART App Launch IG. As of the date this 
proposed rule appears in the Federal Register, the most recently 
published version is the FAST Security IG, Version 2.0.0--STU 2.

    \67\ Health Level Seven International. (n.d.). FAST Security IG. 
Retrieved from https://build.fhir.org/ig/HL7/fhir-udap-security-ig/.
---------------------------------------------------------------------------

    We are recommending the FAST Security IG, rather than proposing to 
require it, given nascent adoption of business-to-business API-based 
technologies among impacted payers. We acknowledge that for the FAST 
Security IG to work successfully, there needs to be an entity or a set 
of entities to manage the trust between participating organizations 
(trust community). While the FAST Security

[[Page 19913]]

IG provides for client registration, authentication, and authorization, 
the entity that performs the registration must have a ``trust 
relationship'' established.
    CMS is considering whether it would be valuable to recommend 
additional authentication and authorization standards within FHIR. One 
authentication and authorization method that can be used within the 
FAST Security IG is Tiered Open Authorization (Tiered 
OAuth).68 69 Tiered OAuth enables the federation of digital 
identity management across multiple trusted identity providers using 
the OpenID Core standard. This frees a data holder (such as an impacted 
payer) from having to solely rely on a single identity provider to 
maintain the digital identities across all accessing users.

    In addition to the NCPDP implementation standards discussed in 
sections II.A.2.b. and II.A.2.c. of this proposed rule that facilitate 
the exchange of prescription drug benefit information, we also 
recognize that HL7 has developed a FHIR IG called the CARIN Consumer 
Real-Time Pharmacy Benefit Check (RTPBC) IG.\70\ This IG could enable 
patients to access real-time information about the cost and insurance 
coverage of their prescription medications. Specifically, the RTPBC IG 
could help patients determine their benefit coverage, estimate their 
out-of-pocket costs for specific drugs at the pharmacy, and explore 
potential alternative medications. While we are not proposing to 
require or recommend adoption of this IG at this time, we acknowledge 
that there may be value in making such information available through 
the Patient Access API.

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

    In summary, we request comment on our recommendations, and 
specifically on the following:
     The recommendation for impacted payers to use the ATR List 
IG to document and share attribution lists that identify whose patient 
data may be shared with a provider through the Provider Access API.
     The recommendation for impacted payers to use the CDex IG 
for the Prior Authorization API for exchanging attachments related to 
prior authorization.
     The recommendation for impacted payers to use the FAST 
Security IG for registration, authentication, and authorization for the 
Patient Access, Provider Access, Payer-to-Payer, and Prior 
Authorization APIs.
     Whether any of these IGs are now mature and important 
enough for CMS to adopt in a final rule.
    In addition, we request comment on the following:
     How can CMS know whether and when the ATR List, CDex, and 
FAST Security IGs are ready for us to propose to require their use?
     Should CMS consider recommending or requiring the FAST 
Security IG ``Tiered OAuth'' in future rulemaking?
     If CMS proposes, in future rulemaking, to require the FAST 
Security IG, should we also propose to require impacted payers to use 
Tiered OAuth for user authentication? If so, to which APIs should that 
proposal apply? Would this be a useful solution to enable 
authentication and authorization at scale?
     Are there trust communities that exist today that impacted 
payers can utilize for business-to-business authentication and 
authorization? Do such communities exist for other stakeholders in the 
health care system, such as providers, or in other industries that 
could be used or expanded for this purpose?
     How much testing is necessary and under what readiness 
conditions would it be appropriate for us to propose to require use of 
the FAST Security IG for the Patient Access, Provider Access, Payer-to-
Payer, and Prior Authorization APIs?
     Should CMS consider recommending the RTPBC IG?
     Are there differences in scope or use cases between the 
RTPBC IG and the Da Vinci PDex Drug Formulary IG? Specifically, would 
RTPBC IG provide additional or distinct benefits compared to the PDex 
Drug Formulary IG, or do the two largely address overlapping use cases?
     Is there value in providing patients with real-time 
prescription drug cost and coverage information through the Patient 
Access API?
     Are there potential technical or operational challenges 
associated with implementing the RTPBC IG within the Patient Access 
API?
     Is there enough patient demand via third-party apps to 
justify the burden of implementing the RTPBC IG?
     Do any third-party apps currently include this 
functionality, or would developers build it, if recommended?
     Do payers or PBMs currently support the required technical 
standards to enable third-party apps to use the RTPBC IG and would 
payers build that functionality, if recommended?
6. Clarification of Standards for the Provider Directory FHIR API
    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we stated that we were removing the SMART App Launch IG in 45 CFR 
170.215(c)(1) and OpenID Connect Core in 45 CFR 170.215(e), which were 
erroneously included as required standards for the Provider Directory 
API in Table 10 of the 2022 CMS Interoperability and Prior 
Authorization proposed rule (87 FR 76320 and 89 FR 8928) and codified 
in the CFR. CMS also discussed this in the 2020 CMS Interoperability 
and Patient Access final rule, where we finalized a policy that 
security protocols related to user authentication and authorization in 
45 CFR 170.215, namely the SMART App Launch IG and OpenID Connect Core 
standard, would not apply to the Provider Directory API (85 FR 25560).
    We are now proposing that impacted payers be required to implement 
and maintain a Provider Directory API (MA organizations in 42 CFR 
422.120(a), state Medicaid FFS programs in 42 CFR 431.70(a), state CHIP 
FFS programs in 42 CFR 457.760(a), Medicaid managed care plans through 
cross reference to 42 CFR 431.70 in 42 CFR 438.242(b)(6), and CHIP 
managed care entities through cross reference to 42 CFR 438.242 in 42 
CFR 457.1233(d)) conformant with FHIR in 45 CFR 170.215(a) and US Core 
IG in 45 CFR 170.215(b)(1), but not the SMART App Launch IG in 45 CFR 
170.215(c)(1) or OpenID Connect Core in 45 CFR 170.215(e)(1).

B. Electronic Prior Authorization for Drugs

1. Background of the Prior Authorization API
    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we finalized requirements for impacted payers to implement and 
maintain a Prior Authorization API with compliance dates beginning in 
2027 (by January 1, 2027 for MA organizations and state Medicaid and 
CHIP FFS programs; by the rating period beginning on or after January 
1, 2027 for Medicaid managed care plans and CHIP managed care entities; 
and for plan years beginning on or after January 1, 2027 for individual 
market QHP issuers on the FFEs).\96\ The Prior Authorization API 
enables providers to conduct electronic prior authorizations directly 
from their EHRs or other health IT systems by determining whether a 
payer requires prior authorization for a particular item or service, 
accessing coverage and documentation requirements, submitting the prior 
authorization request, and receiving a response to that request, 
thereby easing a significant point of administrative burden.
---------------------------------------------------------------------------

    \96\ See 42 CFR 422.122(b) for MA organizations, 42 CFR 
431.80(b) for state Medicaid FFS programs, 42 CFR 457.732(b) for 
state CHIP FFS programs, through cross reference to 42 CFR 431.80(b) 
in 42 CFR 438.242(b)(7) for Medicaid managed care plans, through 
cross reference to 42 CFR 438.242 in 42 CFR 457.1233(d) for CHIP 
managed care entities, and 45 CFR 156.223(b) for individual market 
QHP issuers on the FFEs.
---------------------------------------------------------------------------

    In that final rule, we limited the required content accessible 
through the Prior Authorization API to non-drug items and services. We 
excluded all drugs covered by impacted payers (for example, drugs that 
may be self-administered, administered by a provider, or that may be 
dispensed or administered in a pharmacy or hospital) (89 FR 8762). We 
explained in the 2022 CMS Interoperability and Prior Authorization 
proposed rule and 2024 CMS Interoperability and Prior Authorization 
final rule that existing processes and standards for prior 
authorization of drugs differ significantly from those for non-drug 
items and services (87 FR 76240-76241 and 89 FR 8765).

[[Page 19922]]

    In response to the 2022 CMS Interoperability and Prior 
Authorization proposed rule, we received numerous comments requesting 
that we reconsider the exclusion of drugs from the proposed 
requirements. Those comments stated that providers face similar 
challenges with prior authorizations for drugs as with non-drug items 
and services, and that the current prior authorization processes 
sometimes delay access to medically necessary drug treatments. 
Commenters noted that the inconsistent use of technology and standards 
can create barriers to care and burden both providers and payers. For 
example, providers are sometimes unaware that a prior authorization is 
required until a payer rejects a prescription claim presented to a 
pharmacy, which causes delays for patients to receive necessary 
medication and affects the provider's ability to timely identify and 
prescribe an alternative medication. In many cases, providers still 
have to use fax, telephone, or payer-specific web portals for drug 
prior authorizations. While portals are used for data entry, they 
typically do not provide immediate feedback to providers about prior 
authorization requirements or accept supporting documentation, nor do 
they provide real time responses. Thus, current methods can be 
inefficient and create additional process challenges (89 FR 8765-8766).
    Many commenters, including payers and providers, advocated that 
prior authorization for drugs could and should be incorporated into the 
Prior Authorization API. Commenters specifically emphasized the need 
for more streamlined electronic prior authorization processes for drugs 
administered in a medical setting, such as infusions, oral cancer 
drugs, oral antiemetics, and drugs for terminal or chronic conditions, 
such as cancer or multiple sclerosis. Other commenters pointed to 
existing rules that require Medicare Part D sponsors to offer 
electronic prior authorization for covered Part D drugs via a standard 
adopted by the Secretary, which includes NCPDP SCRIPT standard versions 
2017071 and 2023011, adopted in 45 CFR 170.205(b)(1) and 45 CFR 
170.205(b)(2) (89 FR 8765-8766).
    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we stated that we would gather additional information and 
consider opportunities for future rulemaking (89 FR 8765). After 
considering stakeholder comments, our goals for interoperability, and 
the technical standards available to support electronic prior 
authorization for drugs, we are now proposing to require impacted 
payers to support electronic prior authorization for all drugs using a 
combination of standards, including the HL7[supreg] FHIR[supreg] 
standards that compose the Prior Authorization API and the NCPDP 
standards required for covered Part D drugs.
2. Existing Standards for Electronic Prior Authorizations
a. Electronic Prior Authorization API
    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we finalized requirements for impacted payers to implement and 
maintain a FHIR API to facilitate prior authorization for non-drug 
items and services.\97\ The FHIR standards are designed to support the 
interoperable exchange of health care information. In that final rule, 
we also recommended impacted payers use certain IGs within their Prior 
Authorization APIs, namely the CRD IG, DTR IG, and PAS IG (89 FR 8861). 
Details about the standards and IGs for the Prior Authorization API, 
including proposals to now require those IGs, are in section II.A. of 
this proposed rule. The IGs provide consistent formats to discover 
coverage and documentation requirements and exchange prior 
authorization requests and responses. The IGs include a set of 
workflows designed to support the exchange of prior authorization 
information, which includes drugs covered under a medical benefit and 
excludes those covered under a pharmacy benefit for which prior 
authorization is facilitated by another electronic exchange process 
(for example, the NCPDP SCRIPT standard).
---------------------------------------------------------------------------

    \97\ See 42 CFR 422.122(b) for MA organizations, 42 CFR 
431.80(b) for state Medicaid FFS programs, 42 CFR 457.732(b) for 
state CHIP FFS programs, through cross reference to 42 CFR 431.80(b) 
in 42 CFR 438.242(b)(7) for Medicaid managed care plans, through 
cross reference to 42 CFR 438.242 in 42 CFR 457.1233(d) for CHIP 
managed care entities, and 45 CFR 156.223(b) for individual market 
QHP issuers on the FFEs.
---------------------------------------------------------------------------

b. X12N 278 Transaction Standard for Prior Authorization(s)
    Under the HIPAA Administrative Simplification rules, the Secretary 
has adopted standards for use by covered entities--which includes all 
impacted payers--for, among other transactions, referral certification 
and authorization, a subset of which are used for prior 
authorization.\98\ In January 2024, HHS announced it was exercising its 
enforcement discretion regarding the standard adopted under HIPAA for 
electronic prior authorization, the X12N 278 transaction standard.\99\ 
HHS announced that it would not take enforcement action against HIPAA 
covered entities that, as part of a Prior Authorization API, do not use 
the X12N 278 transaction standard. HHS issued that notice of 
enforcement discretion based on substantial industry and stakeholder 
comments regarding the potential requirement to use the X12N 278 
transaction standard in combination with the Prior Authorization API. 
Stakeholders informed HHS that requiring the HIPAA standard to be used 
within the FHIR standard would be duplicative, unnecessary, and 
burdensome. HHS's exercise of enforcement discretion is intended to 
promote efficiency. In section II.H.3. of this proposed rule, HHS is 
proposing to replace the X12N 278 transaction standard by adopting the 
Prior Authorization API as the HIPAA standard for prior authorization-
related transactions.

Based Prior Authorization API. Retrieved from https://www.cms.gov/files/document/discretion-x12-278-enforcement-guidance-letter-remediated-2024-02-28.pdf.
---------------------------------------------------------------------------

c. The NCPDP SCRIPT Standard for Electronic Prior Authorizations
    The 2020 Medicare Part D ePA final rule (85 FR 86824-86827) 
extensively details the NCPDP SCRIPT standard's history. For context, 
we provide here some of the narrative from that final rule. Congress 
required electronic prior authorization in the Substance Use Disorder 
Prevention that Promotes Opioid Recovery and Treatment for Patients and 
Communities Act (hereinafter referred to as the ``SUPPORT Act'') (Pub. 
L. 115-271, enacted October 24, 2018). Section 6062 of the SUPPORT Act 
amended section 1860D-4(e)(2) of the Act to require Part D sponsors and 
prescribing health care professionals to use technical standards 
adopted by the Secretary when transmitting electronic prior 
authorization requests and responses for coverage of a covered Part D 
drug for a Part D eligible individual enrolled in a Part D plan (PDP).
    The 2020 Medicare Part D ePA final rule established the NCPDP 
SCRIPT standard version 2017071 as the required standard for electronic 
prior authorization for covered Part D drugs in 42 CFR 423.160(b)(8) 
(85 FR 86832). Part D sponsors and providers were permitted to use the 
standard beginning

[[Page 19923]]

January 1, 2021 and were required to do so beginning January 1, 2022.
    In the 2024 Part D and Health IT Standards final rule, ONC 
finalized a January 1, 2028 expiration date for the NCPDP SCRIPT 
standard version 2017071 in 45 CFR 170.205(b)(1) and adopted the NCPDP 
SCRIPT standard version 2023011 in 45 CFR 170.205(b)(2). In the same 
final rule, CMS finalized the requirement in 42 CFR 423.160(b)(1) that 
communication of electronic prior authorization must comply with a 
standard in 45 CFR 170.205(b). Therefore, Part D sponsors, providers, 
and dispensers are permitted to use either version of the NCPDP SCRIPT 
standard to conduct electronic prior authorization for drugs until 
January 1, 2028, when the NCPDP SCRIPT standard version 2023011 must be 
used exclusively (89 FR 51247).
d. Other HIPAA Standards for Pharmacy Transactions
    In 2009, the Secretary adopted the NCPDP Telecommunication Standard 
IG, Version D, Release 0 (Version D.0) as a HIPAA Administrative 
Simplification transaction standard to improve the efficiency of retail 
pharmacy transactions.\100\ Version D.0 is used for retail pharmacy 
electronic transactions between pharmacies and payers. Version D.0 
allows for accurate and consistent data exchange, reduces errors in 
claims processing, enhances eligibility and benefits verification, and 
streamlines pharmacy transactions, contributing to an efficient health 
care exchange for pharmacies, health care clearinghouses (where used as 
an intermediary between pharmacies and payers), and payers. Though 
Version D.0 is largely used for claims and eligibility transactions, it 
also includes the capability to transmit prior authorization requests 
from, and responses to, pharmacies.
---------------------------------------------------------------------------

    \100\ See 45 CFR 162.1302.
---------------------------------------------------------------------------

    On December 13, 2024, the ``Administrative Simplification: 
Modifications of Health Insurance Portability and Accountability Act of 
1996 (HIPAA) National Council for Prescription Drugs (NCPDP) Retail 
Pharmacy Standards; and Modification of the Medicaid Pharmacy 
Subrogation Standard'' final rule (89 FR 100763) (hereinafter referred 
to as the ``2024 HIPAA NCPDP Pharmacy Standards final rule'') appeared 
in the Federal Register. In that final rule, the Secretary adopted the 
NCPDP Telecommunication Standard IG, Version F6 (Version F6) to replace 
Version D.0 to address emerging industry needs and improve the accuracy 
of pharmacy claim transactions, such as larger fields to accommodate 
increasingly expensive drugs (89 FR 100767-100768).
    The NCPDP Version F6 Telecommunications standard, like Version D.0, 
is designed for transactions between pharmacies and payers, not between 
non-pharmacy providers and payers (89 FR 100767-100768). The CMS 
proposal to require payers to support the NCPDP SCRIPT standard for 
electronic prior authorization does not conflict with the HIPAA 
transaction standard because electronic prior authorizations utilizing 
the NCPDP SCRIPT standard are not intended to be used by pharmacies. 
This rulemaking does not affect pharmacies, which will continue to be 
required by HIPAA to use Version F6.
3. Proposed Requirement To Incorporate Drugs Covered Under a Medical 
Benefit Into the Prior Authorization API for All Impacted Payers
    We are now proposing to require impacted payers to expand the scope 
of the required Prior Authorization API to incorporate drugs covered 
under a medical benefit, as that term is explained in section I.C. of 
this proposed rule. We are proposing an October 1, 2027 compliance date 
for MA organizations, state Medicaid and CHIP FFS programs, Medicaid 
managed care plans, CHIP managed care entities, and QHP issuers on the 
FFEs.
    Stakeholder input indicates that enhancing the Prior Authorization 
API by incorporating drugs covered under a medical benefit would 
improve the prior authorization process by giving providers and 
patients more timely information about prior authorization requirements 
to obtain these drugs. As with non-drug items and services, a Prior 
Authorization API enables EHRs or other health IT to determine whether 
prior authorization is required, collect documentation, and submit a 
request. Expanding the scope of impacted payers' Prior Authorization 
APIs to incorporate drugs covered under a medical benefit would 
streamline the administrative process for providers and result in 
payers receiving more complete requests and fewer unnecessary requests, 
which could accelerate decision-making. Reducing those burdens should 
mitigate ambiguity and reduce delays in providing patients with 
medically necessary drugs.
    Therefore, we are proposing to require impacted payers to enhance 
their Prior Authorization APIs by incorporating prior authorization 
coverage and documentation requirements for drugs covered under a 
medical benefit, as we describe that term in section I.C. of this 
proposed rule, beginning October 1, 2027. The IGs we are proposing to 
require for the Prior Authorization API include a set of workflows 
designed to support prior authorization. Those workflows specifically 
include drugs covered under a medical benefit and exclude drugs covered 
under a pharmacy benefit, for which prior authorization is conducted by 
another electronic exchange process, such as the NCPDP SCRIPT standard.
    We emphasize that adding drugs covered under a medical benefit to 
the non-drug items and services included in the Prior Authorization API 
requires no changes to the existing standards, the IGs we are proposing 
to require in section II.A. of this proposed rule, or other recommended 
IGs. Furthermore, the functionality of the Prior Authorization API 
would not need to be modified, but the specific coverage and 
documentation requirements for drugs covered under a medical benefit 
would have to be added to the content available via the API.\101\

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

    While we describe some of the types of drugs that might be covered 
under a medical benefit versus a pharmacy benefit for each payer in 
section I.C. of this proposed rule, we do not intend to specify an 
exhaustive list of drugs covered under a medical benefit, as each payer 
structures their formularies differently while following statutory and 
regulatory coverage requirements. For example, while certain infusions, 
injections, and services conducted in a provider's office could be 
included under a medical benefit, self-administered oral medications 
would likely be included under a pharmacy benefit. However, we intend 
the categories of ``drugs covered under a medical benefit'' and ``drugs 
covered under a pharmacy benefit'' to be mutually exclusive and 
collectively include all drugs covered by any particular payer. Put 
differently, we are proposing that electronic prior authorization must 
be available for all drugs covered by any impacted payer for which they 
require prior authorization, either through the Prior Authorization API 
or NCPDP SCRIPT standards adopted by the Secretary.
    In Medicare FFS, drugs are either payable by Part A or Part B, or 
covered by Part D prescription drug coverage. Medicare Part B may pay 
for prescription drugs and biologicals (hereinafter referred to as 
``drugs'')

[[Page 19924]]

administered in an outpatient setting under certain conditions, for 
example, drugs provided as part of (or incident to) a physician's 
service and drugs furnished for use with covered DMEPOS items. Many 
drugs payable under Part A or Part B are infused or injected by 
physicians such as oncologists, rheumatologists, and urologists. Drugs 
payable by Part A or Part B are not usually self-administered. Medicare 
Part D is the prescription drug benefit of Medicare, which covers most 
outpatient prescription drugs through Plan D sponsors and MA 
organizations offering MA-PD plans. Covered Part D drugs are defined in 
section 1860D-2(e) of the Act. A Part D drug is further defined in 42 
CFR 423.100 and includes the following, if used for a medically 
accepted indication as defined by section 1860D-2(e)(4) of the Act:
     A drug that may be dispensed only upon a prescription that 
is described in sections 1927(k)(2)(A)(i) through (iii) of the Act.
     A biological product described in sections 
1927(k)(2)(B)(i) through (iii) of the Act.
     Insulin described in section 1927(k)(2)(C) of the Act.
     Medical supplies associated with the injection of insulin.
     A vaccine licensed under section 351 of the Public Health 
Service Act (hereinafter referred to as the ``PHSA'') (Pub. L. 115-5, 
enacted November 21, 1997) and its administration.
     A combination product approved and regulated by the Food 
and Drug Administration (FDA) as a drug, vaccine, or biologic.
    The following are excluded from the definition of Part D drugs:
     Drugs for which payment as so prescribed and dispensed or 
administered to an individual is available for that individual under 
Part A or Part B.
     Drugs that may be excluded from coverage or otherwise 
restricted under sections 1927(d)(2) or (d)(3) of the Act, except for 
smoking cessation agents.
     Medical foods that are not regulated as drugs under 
section 505 of the Federal Food, Drug, and Cosmetic Act (Pub. L. 75-
717, enacted June 25, 1938).
    With some limited exceptions, MA plans are statutorily required to 
cover Part A and Part B benefits, including drugs. Most MA plans also 
include Part D prescription drug coverage for their Medicare enrollees. 
These MA-PDs include drug coverage as a single plan, and patients 
enrolled in an MA-PD plan likely do not experience a distinction 
between drugs that are payable under Part A or Part B and those covered 
under Part D. Medicare patients who are enrolled in an MA plan that 
cannot offer Part D coverage (like Medical Savings Account plans) or 
choose not to offer Part D coverage (like certain MA-only plans) can 
join a separate, standalone PDP.
    For MA plans, the term ``drugs covered under a pharmacy benefit'' 
as used in this proposed rule means covered Part D drugs, as defined in 
42 CFR 423.100. Conversely, ``drugs covered under a medical benefit'' 
as used in this rule means any drugs payable under Part A or Part B.
    For Medicaid, although ``prescribed drugs'' is an optional Medicaid 
benefit category under section 1905(a)(12) of the Act, all states 
currently provide this benefit for all categorically eligible 
individuals and most other enrollees within their Medicaid programs. 
States are permitted to apply prior authorization requirements to 
covered outpatient drugs as long as the prior authorization program 
complies with the requirements of section 1927(d)(5) of the Act.\102\ 
Medicaid managed care plans must conduct their prior authorization 
programs in compliance with the requirements of section 1927(d)(5) of 
the Act, as if such requirements applied to the Medicaid managed care 
plan, if covered outpatient drugs are included in their contracts.\103\ 
For CHIP, section 2110(a)(6) of the Act authorizes states to cover 
drugs within CHIP. For CHIP managed care entities, 42 CFR 457.1230(d) 
cross references to the Medicaid managed care regulations in 42 CFR 
438.210.
---------------------------------------------------------------------------

    \102\ Per section 1927(k)(3) of the Act and 42 CFR 447.502, 
drugs that are provided as part of, or as incident to and in the 
same setting as a service, and for which payment is made in Medicaid 
as payment for part of the service, and not as direct reimbursement 
are not ``covered outpatient drugs.'' Accordingly, the prior 
authorization requirements in section 1927(d)(5) of the Act do not 
apply to such drugs.
    \103\ See 42 CFR 438.3(s)(6).
---------------------------------------------------------------------------

    For Medicaid and CHIP FFS, we believe that the distinction between 
drugs within the proposed scope of the Prior Authorization API and 
within the scope of the proposed NCPDP standards can be distinguished 
by the systems used to process claims. We expect drugs that are 
processed in a claims adjudication system that is not at the point of 
sale would be within the proposed scope of the Prior Authorization API. 
Conversely, we expect that drugs that are processed in a point of sale 
or real-time claims adjudication system would be within the scope of 
the proposed NCPDP standards. Thus, the systems that state Medicaid and 
CHIP FFS programs use to process claims may serve as an effective 
framework for determining which drugs fit within the scope of the Prior 
Authorization API and which drugs fit within the scope of the NCPDP 
standards.
    States that cover drugs under state Medicaid or CHIP FFS or both 
programs generally use their Medicaid Management Information System 
(MMIS) to process medical claims and another pharmacy system, such as 
an electronic claims management system (ECMS), described in 42 CFR 
456.722, or PBM, to process pharmacy claims. We believe that the 
systems that states use to process claims may be directly relevant to 
the state's determination of whether the proposed FHIR or NCPDP 
standards should apply for particular prior authorization requests. To 
meet the requirements of the 2024 CMS Interoperability and Prior 
Authorization final rule, states should already be planning to 
integrate the Prior Authorization API for non-drug items and services 
with their MMIS or related systems.\104\ States (or their PBMs) may be 
able to build the proposed NCPDP standards into the state Medicaid and 
CHIP FFS pharmacy systems. If those systems accurately align with the 
scope of each standard, states could use the proposed standards for the 
electronic prior authorization of drugs into separate systems without 
duplication or overlap. We also emphasize that this dichotomy should 
not and, if finalized, would not affect any other Medicaid or CHIP 
policies related to drug coverage.

    Section 1301(a)(1)(B) of the Patient Protection and Affordable Care 
Act, as amended by the Health Care and Education Reconciliation Act of 
2010 (hereinafter referred to as the ``Affordable Care Act'') (Pub. L. 
111-148, enacted March 23, 2010 and Pub. L. 111-152, enacted March 30, 
2010), and section 2707 of the PHSA require QHP issuers on the FFEs to 
cover the essential health benefits (EHBs), which includes items and 
services in the categories described in section 1302(b) of the 
Affordable Care Act, one of which is prescription drugs. There is no 
statutory or regulatory distinction between drugs covered under a 
medical benefit, as described by the scope of the Prior Authorization 
API, and drugs covered under a pharmacy benefit, as described by the 
NCPDP SCRIPT standard, for QHP issuers on the FFEs. There are also no 
existing requirements for QHP issuers on the FFEs to support electronic 
prior authorization for drugs

[[Page 19925]]

in either category. However, we understand that most QHP issuers on the 
FFEs structure benefits into medical and pharmacy categories and 
therefore should follow their own distinctions for drug coverage.
    Should these electronic prior authorization proposals be finalized, 
impacted payers would need to review the list of covered drugs for 
which they require prior authorization to determine whether they fit 
into the scope of the Prior Authorization API (drugs covered under a 
medical benefit) or the NCPDP SCRIPT standard (drugs covered under a 
pharmacy benefit). Once each payer has evaluated those drugs that 
require prior authorization and identified those that may be processed 
through the Prior Authorization API, the applicable rules, 
requirements, and templates would need to be developed and incorporated 
into the API.
    We are proposing compliance dates beginning October 1, 2027 for 
this proposal. We believe 1 year is the appropriate period for impacted 
payers to evaluate and incorporate the additional prior authorization 
rules and requirements into their Prior Authorization API. In response 
to the 2022 CMS Interoperability and Prior Authorization proposed rule, 
commenters stated that payers and developers generally need 1 to 2 
years to implement a new system (89 FR 8824-8825). In the 2024 CMS 
Interoperability and Prior Authorization final rule, we finalized 
compliance dates for policies that require API development and 
enhancement beginning in 2027, which provided impacted payers 
approximately 3 years to implement the finalized requirements (89 FR 
8784, 8817, 8855, and 8897). That feedback was based on the totality of 
our policies that require API development or enhancement--to require 
three new APIs and to update the Patient Access API. This proposal 
would not require impacted payers to build new APIs from scratch, but 
to incorporate prior authorization requirements for drugs covered under 
a medical benefit into the existing Prior Authorization APIs. Based on 
previous industry feedback on development timelines and our experience 
implementing the CMS Medicare FFS Prior Authorization API, we believe 
the effort to add those prior authorization rules to the API would not 
require more than a year.
    In summary, we request comment on our proposals in the CFR 
citations listed in Table 4, and specifically on the following:
     The proposal to require impacted payers to incorporate 
coverage and documentation requirements into the Prior Authorization 
API to support electronic prior authorization for drugs covered under a 
medical benefit, as that term describes the scope of the Prior 
Authorization API FHIR standards.
     The proposed October 1, 2027 compliance date for MA 
organizations, state Medicaid and CHIP FFS programs, Medicaid managed 
care plans, CHIP managed care entities, and QHPs issuers on the FFEs.
    In addition, we request comments on the following:
     Is the scope of the Prior Authorization API, as defined by 
its implementation guidance and the description of drugs covered under 
a medical benefit, clear and appropriate for impacted payers?
     For MA organizations, are there drugs other than those 
payable under Part B, such as supplemental benefits, that should be 
covered by our proposals to require MA organizations to support 
electronic prior authorization?
     Is the rubric to categorize drugs as within the scope of 
the Prior Authorization API (covered under a medical benefit) or within 
the scope of the NCPDP standards (covered under a pharmacy benefit) 
based on the system through which the claims are processed applicable 
to and appropriate for all or most state Medicaid and CHIP FFS 
programs?
     Is the system through which claims are processed the 
accurate and appropriate way to differentiate the categories of drugs 
that are within scope of the Prior Authorization API versus the NCPDP 
standards for other types of impacted payers?
4. Proposed Requirement To Support the NCPDP SCRIPT Standard for Prior 
Authorization for State Medicaid and CHIP Fee-for-Service Programs, 
Medicaid Managed Care Plans, CHIP Managed Care Entities, and Qualified 
Health Plan Issuers on the Federally-facilitated Exchanges
    We propose to require state Medicaid and CHIP FFS programs, 
Medicaid managed care plans, CHIP managed care entities, and QHP 
issuers on the FFEs to support an unexpired version of the NCPDP SCRIPT 
standard adopted by the Secretary in 45 CFR 170.205(b) for the 
electronic prior authorization of drugs covered under a pharmacy 
benefit, as that term is described in the standard, further discussed 
in section I.C. of this proposed rule. We are making these proposals in 
response to comments we received on the 2022 CMS Interoperability and 
Prior Authorization proposed rule that stated that requiring impacted 
payers to support electronic prior authorization of drugs would support 
faster access to necessary medications for patients and reduce 
administrative burden on providers.
    We are proposing an October 1, 2027 compliance date for state 
Medicaid and CHIP FFS programs, Medicaid managed care plans, CHIP 
managed care entities, and QHP issuers on the FFEs. Requiring state 
Medicaid and CHIP FFS programs, Medicaid managed care plans, CHIP 
managed care entities, and QHP issuers on the FFEs to support an 
unexpired version of the NCPDP SCRIPT standard adopted by the Secretary 
would align requirements for these payers with the existing requirement 
for Medicare Part D sponsors, prescribers, and dispensers in 42 CFR 
423.160(b)(1).
    Specifically, as discussed in section II.A. of this proposed rule, 
we propose that those impacted payers would be required to support an 
adopted version of the NCPDP SCRIPT standard to enable providers to 
electronically submit prior authorization requests and receive prior 
authorization decisions for drugs covered under a pharmacy benefit 
using the following transactions:
     PAInitiationRequest and PAInitiationResponse
     PARequest and PAResponse
     PAAppealRequest and PAAppealResponse
     PACancelRequest and PACancelResponse
     PANotification (NCPDP SCRIPT standard version 2023011 
only)
    We are not proposing to require providers to use electronic prior 
authorization in this proposed rule. Rather, we are proposing that an 
unexpired version of the NCPDP SCRIPT standard adopted by the Secretary 
must be available for providers to use for prior authorization, and 
that the payer must send the response to the prior authorization 
request using the same standard. If ONC establishes an expiration date 
for an adopted version of the NCPDP SCRIPT standard in 45 CFR 
170.205(b), upon the specified expiration date, that version would no 
longer be eligible for use by impacted payers to meet the 
interoperability requirements. State Medicaid and CHIP FFS programs, 
Medicaid managed care plans, CHIP managed care entities, and QHP 
issuers on the FFEs may continue to make non-electronic means of 
conducting prior authorization (for example, fax, phone call, or direct 
data entry through a payer portal) available to providers. However, 
should these proposals be finalized, an unexpired version of the NCPDP 
SCRIPT standard adopted by the Secretary would be the only electronic 
method these payers would be

[[Page 19926]]

permitted to use for the prior authorization of drugs covered under a 
pharmacy benefit as that term is described by the implementation 
guidance of the NCPDP SCRIPT standard, as discussed in sections II.A.2. 
and II.A.3. of this proposed rule.
    The NCPDP SCRIPT standard is already used by Medicare Part D 
sponsors, prescribers, and dispensers and required for various purposes 
by 15 states (for example, for electronic prior authorization and for 
electronic prescribing). The proposal to require other impacted payers 
to support the standard should create greater efficiency for providers 
and drive interoperability across CMS programs.\105\

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

    We propose an October 1, 2027 compliance date for state Medicaid 
and CHIP FFS programs, Medicaid managed care plans, CHIP managed care 
entities, and QHP issuers on the FFEs to support an unexpired version 
of the NCPDP SCRIPT standard adopted by the Secretary. That aligns with 
the feedback we received in response to the 2022 CMS Interoperability 
and Prior Authorization proposed rule that payers and developers 
generally need at least a year to implement a new system (89 FR 8824). 
In the 2024 CMS Interoperability and Prior Authorization final rule, we 
finalized compliance dates beginning in 2027 for policies that require 
API development and enhancement. That afforded impacted payers 
approximately 3 years to implement from when the rule was finalized (89 
FR 8784, 8817, 8855, and 8897). That feedback was based on the totality 
of our proposals that require API development or enhancement--to 
require three new APIs and to update the Patient Access API. We believe 
it is appropriate to afford payers and developers approximately a year 
to implement this proposal, which will require time for programming, 
testing, education, and outreach.
    In summary, we request comment on our proposals in the CFR 
citations listed in Table 4, and specifically on the following:
     The proposal to require state Medicaid and CHIP FFS 
programs, Medicaid managed care plans, CHIP managed care entities, and 
QHP issuers on the FFEs to support an unexpired version of the NCPDP 
SCRIPT standard adopted by the Secretary in 45 CFR 170.205(b) for the 
electronic prior authorization of drugs covered under a pharmacy 
benefit.
     The proposal to require state Medicaid and CHIP FFS 
programs, Medicaid managed care plans, CHIP managed care entities, and 
QHP issuers on the FFEs to support an adopted version of the NCPDP 
SCRIPT standard using the following transactions: PAInitiationRequest, 
PAInitiationResponse, PARequest, PAResponse, PAAppealRequest, 
PAAppealResponse, PACancelRequest, PACancelResponse, and PANotification 
(currently NCPDP SCRIPT standard version 2023011 only).
     The proposed October 1, 2027 compliance date for state 
Medicaid and CHIP FFS programs, Medicaid managed care plans, CHIP

5. Proposed Requirement To Support the NCPDP Formulary and Benefit 
Standard for State Medicaid and CHIP Fee-for-Service Programs, Medicaid 
Managed Care Plans, CHIP Managed Care Entities, and Qualified Health 
Plan Issuers on the Federally-facilitated Exchanges
    We are proposing to require state Medicaid and CHIP FFS programs, 
Medicaid managed care plans, CHIP managed care entities, and QHP 
issuers on the FFEs to support an unexpired version of the NCPDP F&B 
standard adopted by the Secretary in 45 CFR 170.205(u) by October 1, 
2027. Accordingly, upon the specified expiration date of a version of 
the NCPDP F&B standard adopted in 45 CFR 170.205(u), that version would 
no longer be eligible for use by impacted payers to meet this proposal, 
if finalized.
    As discussed in section II.A.2.b. of this proposed rule, the NCPDP 
F&B standard enables providers to view formulary and benefit 
information at a group level. The NCPDP F&B standard supports the NCPDP 
SCRIPT standard by giving providers information at the point of 
prescribing about whether a payer covers a particular drug and whether 
the payer requires prior authorization. Therefore, our proposal to 
require impacted payers to support an unexpired version of the NCPDP 
F&B standard adopted by the Secretary should enhance providers' ability 
to electronically request prior authorization for drugs covered under a 
pharmacy benefit. As with our other proposals, the NCPDP F&B standard 
should enable a more seamless exchange of prior authorization 
requirements, which should help state Medicaid and CHIP FFS programs, 
Medicaid managed care plans, CHIP managed care entities, and QHP 
issuers on the FFEs more efficiently manage their pharmacy benefits and 
prior authorization programs. A standardized approach to providing 
formulary and prior authorization information could make provider and 
payer operations more efficient and reduce costs.
    The 2024 Part D and Health IT Standards final rule also includes 
requirements for transmitting formulary and benefits information 
between Part D sponsors and providers using the NCPDP F&B standard. 
Specifically, until January 1, 2027, that rule requires Part D sponsors 
to use either NCPDP F&B standard version 3.0 or an unexpired version of 
the NCPDP F&B standard adopted by the Secretary in 45 CFR 170.205(u). 
Beginning January 1, 2027, Part D sponsors are required to use an 
unexpired version of a standard adopted by the Secretary in 45 CFR 
170.205(u), which is currently NCPDP F&B standard version 60 (89 FR 
51250-51251).\106\ Our proposal to require the other types of impacted 
payers (state Medicaid and CHIP FFS programs, Medicaid managed care 
plans, CHIP managed care entities, and QHP issuers on the FFEs) to 
implement an unexpired version of the NCPDP F&B standard adopted by the 
Secretary in 45 CFR 170.205(u) would align payers and should reduce the 
burden on providers currently using disparate systems and standards 
across payers.

programs, Medicaid managed care plans, CHIP managed care entities, and

6. Proposed Requirement To Support the NCPDP Real-Time Prescription 
Benefit Standard for State Medicaid and CHIP Fee-for-Service Programs, 
Medicaid Managed Care Plans, CHIP Managed Care Entities, and Qualified 
Health Plan Issuers on the Federally-facilitated Exchanges
    We also propose that state Medicaid and CHIP FFS programs, Medicaid 
managed care plans, CHIP managed care entities, and QHP issuers on the 
FFEs support an unexpired version of the NCPDP RTPB standard adopted by 
the Secretary in 45 CFR 170.205(c) by October 1, 2027.
    The 2024 Part D and Health IT Standards final rule requires, 
beginning January 1, 2027, Part D sponsors' real-time benefit tools to 
comply with an unexpired version of a standard adopted by the Secretary 
in 45 CFR 170.205(c) (89 FR 51247 and 51251).\107\ Currently, the 
version of the NCPDP RTPB standard that the Secretary has adopted in 45 
CFR 170.205(c) is NCPDP RTPB standard version 13, adopted in 45 CFR 
170.205(c)(1). As discussed in section II.A.2.c. of this proposed rule, 
the NCPDP RTPB standard enables real-time, patient-specific 
prescription benefit information to be delivered to providers at the 
point of prescribing. This proposal should coalesce support for the 
NCPDP SCRIPT standard and improve efficiency and accuracy. By 
integrating the NCPDP RTPB standard into the prior authorization 
process, payers could provide immediate feedback to providers about a 
patient's coverage, including whether a drug covered under a pharmacy 
benefit requires prior authorization, alternative covered medications, 
and patient out-of-pocket costs. State Medicaid and CHIP FFS programs, 
Medicaid managed care plans, CHIP managed care entities, and QHP 
issuers on the FFEs could reduce administrative costs by providing 
prior authorizations and coverage information up front by avoiding 
unnecessary requests. Providers and patients could benefit from 
implementing the NCPDP RTPB standard because real-time benefit 
information could reduce care delays or unexpected costs.

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

    Our proposal to require these standards continues our goal towards 
interoperability and adoption of modern standards, reducing industry 
fragmentation. This standardization could encourage innovation and 
development of more sophisticated clinical decision support tools.
    In summary, we request comment on our proposals in the CFR 
citations listed in Table 4, and specifically on the following:
     The proposal to require state Medicaid and CHIP FFS 
programs, Medicaid managed care plans, CHIP managed care entities, and 
QHP issuers on the FFEs to support an unexpired version of the NCPDP 
RTPB standard adopted by the Secretary in 45 CFR 170.205(c) to make 
available real-time coverage information for drugs covered under a 
pharmacy benefit.
     The proposed October 1, 2027 compliance date for state 
Medicaid and CHIP FFS programs, Medicaid managed care plans, CHIP 
managed care entities, and QHP issuers on the FFEs.
7. Extensions, Exemptions, and Exceptions
    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we finalized processes for state Medicaid and CHIP FFS programs 
to request an extension to the compliance date or an exemption from 
requirements to build some of the interoperability APIs if they meet 
certain criteria.\108\ We also finalized a process for individual 
market QHP issuers on the FFEs to request an exception from the 
requirement to build the interoperability APIs under certain 
circumstances.\109\
---------------------------------------------------------------------------

    \108\ For the Provider Access and Payer-to-Payer APIs, see 42 
CFR 431.61(c) for state Medicaid FFS programs and 42 CFR 457.731(c) 
for state CHIP FFS programs. For the Prior Authorization API, see 42 
CFR 431.80(c) for state Medicaid FFS programs and 42 CFR 457.732(d) 
for state CHIP FFS programs.
    \109\ For the Provider Access and Payer-to-Payer APIs, see 45 
CFR 156.222(c). For the Prior Authorization API, see 45 CFR 
156.223(d).
---------------------------------------------------------------------------

    However, if HHS finalizes its proposal to adopt the FHIR 
specifications that compose the Prior Authorization API as the HIPAA 
standard for ``referral certification and authorization'' transactions 
(further discussed in section II.H. of this proposed rule), it could 
affect impacted payers' (which are HIPAA covered entities) ability to 
request extensions, exemptions, and exceptions from the requirement to 
implement the Prior Authorization API finalized in the 2024 CMS 
Interoperability and Prior Authorization final rule.
a. State Medicaid and CHIP Fee-for-Service Programs
    The process for state Medicaid and CHIP agencies to request an 
exemption from the Prior Authorization API includes requirements, in 42 
CFR 431.80(c)(2)(ii)(B)(2) and 42 CFR 457.732(d)(2)(ii)(B)(2), that 
states must provide an alternative plan to ensure that enrolled 
providers will have efficient electronic access to the same information 
through other means while the exemption is in effect. At the time the 
2024 CMS Interoperability and Prior Authorization final rule was 
finalized and today, the existing HIPAA standard for prior 
authorization transactions is the X12N 278 transaction standard. We 
finalized the exemption process with the understanding that a HIPAA-
compliant X12N 278 transaction standard would be an acceptable 
alternative to meet that requirement. However, if HHS's HIPAA proposals 
in section II.H. are finalized, that standard would no longer be HIPAA-
compliant as of the finalized compliance date.
    Because the purpose of the HIPAA Administrative Simplification 
provisions is to ensure that covered entities do not use electronic 
transactions other than those adopted by the Secretary, there would be 
no other permissible alternative electronic methods for state Medicaid 
and CHIP FFS programs to use. Since there would be no other HIPAA-
permitted alternative electronic methods once HIPAA proposals are 
finalized, state Medicaid and CHIP FFS programs previously eligible for 
an exemption to the Prior Authorization API would no longer have the 
ability to sustain an alternative plan to support electronic prior 
authorization.\110\ The HIPAA Administrative Simplification statute and 
regulations do not provide for exceptions or exemptions, other than 
that described in 45 CFR 162.940 to permit testing of proposed 
modifications. Therefore, in order to ensure that the Prior 
Authorization API exemption requirements finalized in 42 CFR 
431.80(c)(2) for state Medicaid FFS programs and in 42 CFR 
457.732(d)(2) for state CHIP FFS programs do not conflict with the 
proposed HIPAA Administration Simplification requirements, we are 
proposing to remove the policy finalized in the 2024 CMS 
Interoperability and Prior Authorization final rule that allows states 
with small FFS populations to request an exemption from CMS for the 
non-drug items and services Prior Authorization API requirements. If 
finalized as proposed, removal of this policy would result in the 
eventual expiration of any approved exemptions without the possibility 
of renewal. Notably, there are no HIPAA standard transactions related 
to the Patient Access, Provider Directory, Provider Access, or Payer-
to-Payer APIs, so the

[[Page 19928]]

ability to request an exemption for these standards would not be 
affected and we are proposing no changes to the extensions and 
exemptions policies finalized in the 2024 CMS Interoperability and 
Prior Authorization final rule for those APIs.
---------------------------------------------------------------------------

    \110\ See 42 CFR 431.80(c)(2)(ii)(B)(2).
---------------------------------------------------------------------------

    However, to provide additional flexibility to state Medicaid and 
CHIP FFS programs, we are proposing to extend the policy that allows 
any state to request extensions for additional years until the HIPAA 
compliance date, if HHS finalizes its proposals. As discussed in 
section II.H.8. of this proposed rule, we are proposing a multiple year 
gap between the finalized Prior Authorization API compliance dates for 
impacted payers and the proposed compliance dates to our proposals to 
adopt FHIR standards as the HIPAA transaction standard for prior 
authorization transactions. As discussed in section II.H. of this 
proposed rule, we believe it would be appropriate to give 24 months for 
implementation between the effective date of the final rule and the 
proposed compliance date for most covered entities and 36 months for 
small health plans. As defined in 45 CFR 160.103, small health plans 
are those with annual receipts of $5 million or less. As state Medicaid 
and CHIP agencies are not commercial entities, they may generally be 
considered small health plans.\111\ As state Medicaid and CHIP agencies 
are not considered for-profit entities, we would not expect them to 
reach the small health plan $5 million dollar threshold and therefore 
would be considered small health plans for the purpose of granting 
extensions up to 36 months.
---------------------------------------------------------------------------

    \111\ See discussion in 65 FR 82579 that clarifies that ``pure 
premiums'' can be substituted for ``annual receipts,'' as 
appropriate.
---------------------------------------------------------------------------

    Some states may be unable to meet the proposed CMS interoperability 
compliance dates in this proposed rule due to funding challenges for 
necessary contracting and staff resources to develop and implement the 
technical requirements, depending on when the final rule is published 
in relation to a state's FY, legislative session, budget process, and 
related timelines. Some states may need to initiate a public 
procurement process to secure contractors with the necessary skills to 
support a state's implementation of these proposals. The timeline for 
an openly competed procurement process and the time required to onboard 
the contractor and develop the technical capabilities proposed here can 
be lengthy for states. A state might need to hire new staff with the 
necessary skills to implement our finalized policies and proposals to 
require impacted payers to support electronic prior authorization.
    Overlapping requirements with varying timelines and exceptions add 
significant uncertainty to state FFS operations and makes responsible 
stewardship of federal funding more challenging. If HHS finalizes its 
proposals to modify the HIPAA transaction standard for prior 
authorization transactions, states would need to track multiple 
compliance dates, understand which standards are permissible at 
different times, and potentially procure funding and staffing to revise 
new API system implementations accordingly in coordination with state 
legislatures. These requirements, whether final or proposed, come at a 
time when state resources are allocated toward implementation of recent 
statutory changes, notably the Working Families Tax Cut legislation 
(Pub. L. 119-21, enacted July 4, 2025), making it difficult for them to 
reallocate or redirect resources. Providing state Medicaid and CHIP FFS 
programs the ability to request extensions to the compliance dates 
proposed here could mitigate these challenges. In addition, it could 
align with the requirements for covered entities that are not CMS 
impacted payers to use the proposed FHIR standard if they engage in 
electronic prior authorization.
    To align with the proposals to support electronic prior 
authorization for drugs with those for electronic prior authorization 
of non-drug items and services, we also propose to offer similar 
flexibilities for state Medicaid and CHIP FFS programs to request 
extensions to the October 1, 2027 compliance date for the proposed 
requirements to incorporate drugs into the Prior Authorization API and 
to support the NCPDP standards for the electronic prior authorization 
of drugs.
    Should our proposals be finalized, a state Medicaid or CHIP FFS 
program could request from CMS extensions to the compliance dates for 
(1) the non-drug items and services Prior Authorization API 
requirements finalized in the 2024 CMS Interoperability and Prior 
Authorization final rule; (2) the proposal to incorporate drugs into 
the Prior Authorization API; and (3) the proposal to require impacted 
payers to support NCPDP standards for the electronic prior 
authorization of drugs. States must be clear to which of these 
requirements they are requesting an extension and the required 
justification must be attenuated to the specific requirements.
    We propose that a state must submit that request as a part of its 
annual Advance Planning Document (APD) for MMIS operations expenditures 
in sufficient time to be approved before the applicable compliance 
date. The state's request would have to include the following: (1) a 
narrative justification describing the specific reasons why the state 
cannot satisfy the requirement(s) by the compliance date and why those 
reasons result from circumstances that are unique to the agency 
operating the state Medicaid or CHIP FFS program; (2) a report on 
completed and ongoing state activities that evidence a good faith 
effort towards compliance; and (3) a comprehensive plan to meet the 
requirements before a finalized HIPAA compliance date.
    Under this proposal, CMS would approve an extension if, based on 
the information provided in the APD, CMS were to determine that the 
request adequately establishes a need to delay implementation and that 
the state has a comprehensive plan to implement the proposed 
requirements before a finalized HIPAA compliance date.
    We understand that state Medicaid and CHIP FFS programs have 
numerous competing priorities and face additional funding and staff 
limitations compared to commercial entities (89 FR 8902). Therefore, we 
encourage states to contact their Medicaid Enterprise Systems (MES) 
officer, if necessary for proper and efficient operations, to discuss 
their extenuating circumstances. Any flexibility granted to a state 
Medicaid or CHIP FFS program would be temporary and limited to the 
unique circumstances of the program.
b. Exceptions for Qualified Health Plan Issuers on the Federally-
facilitated Exchanges
    In the 2020 CMS Interoperability and Patient Access and the 2024 
CMS Interoperability and Prior Authorization final rules, we finalized 
a process for individual market QHP issuers on the FFEs to submit a 
request for an exception from the technical requirements finalized in 
those rules.\112\ We explained that ability of QHP issuers on the FFEs 
to implement the interoperability APIs might vary based on their 
available resources.
---------------------------------------------------------------------------

    \112\ For the Patient Access API, see 45 CFR 156.221(h). For the 
Provider Access and Payer-to-Payer APIs, see 45 CFR 156.222(c). For 
the Prior Authorization API, see 45 CFR 156.223(d).
---------------------------------------------------------------------------

    Those final rules established that individual market QHP issuers on 
the FFEs that apply for an exception must submit a narrative 
justification as part of their QHP application. That narrative

[[Page 19929]]

justification must describe the reasons why the plan cannot reasonably 
satisfy the requirements for the applicable plan year, the impact of 
non-compliance upon providers and/or enrollees, the current or proposed 
means of providing health information to the applicable recipient, and 
solutions and a timeline to achieve compliance with the requirements of 
the applicable section. As described previously, any current or 
proposed means that differ from the finalized interoperability standard 
must be compliant with the HIPAA administrative simplification 
requirements. In the 2024 CMS Interoperability and Prior Authorization 
final rule, we also noted that QHP issuer certification applications in 
recent years indicated that most QHP issuers on the FFEs are compliant 
with the requirements to implement and maintain a Patient Access API; 
that is, they did not request exceptions through the process. Of the 
QHP issuers on the FFEs that did request exceptions, many explained in 
their justifications that they planned to become compliant with the API 
requirements mid-way through the upcoming plan year (89 FR 8906).
    CMS takes a similar approach during the QHP certification process 
in other instances where flexibility may be warranted based on a QHP 
issuer's circumstances. For example, per 45 CFR 156.230(a)(2)(ii), if a 
plan applying for QHP certification to be offered through the FFE does 
not satisfy the network adequacy standards described in paragraphs 45 
CFR 156.230(a)(2)(i)(A) and 45 CFR 156.230(a)(2)(i)(B), as part of its 
QHP application, the issuer must include a justification describing how 
the plan's provider network provides an adequate level of service for 
enrollees and how the plan's provider network will be strengthened and 
brought closer to compliance with the network adequacy standards prior 
to the start of the plan year. The issuer must provide information as 
requested by the FFE to support this justification. Our experience with 
these exceptions processes for rules that are currently in effect 
suggest that making an exception available prevents the FFE from 
potentially losing issuer participation based on concerns the issuer 
will ultimately be able to address during or before the plan year, 
typically resulting in no potential harm to consumers. In particular, 
we have observed that QHP issuers have submitted narrative 
justifications that may meet or be close to meeting the standards of 
providing an adequate level of service to enrollees by the start of the 
applicable plan year.
    Therefore, we propose an exception process to the proposed NCPDP 
standards requirements for QHP issuers on the FFEs in 45 CFR 
156.223(i). We propose that if an issuer applying for QHP certification 
to be offered through an FFE believes it cannot satisfy the proposed 
requirement to support the proposed NCPDP standards, the issuer would 
have to include in its QHP application a narrative justification 
describing the reasons why it could not satisfy the requirements for 
the applicable plan year, the effect of non-compliance upon providers 
and enrollees, the current or proposed means of providing health 
information to providers and facilitating prior authorization, and 
solutions and a timeline to achieve compliance with the applicable 
requirements.
    We propose that an FFE may grant an exception to the proposed 
requirement to support the NCPDP standards if it determines that making 
QHPs of such issuer available through the Exchange is in the interests 
of qualified individuals and qualified employers in the state or states 
in which the Exchange operates and that an exception is warranted to 
permit the issuer to offer QHPs through the FFE. This proposal is 
consistent with the exceptions for individual market QHP issuers on the 
FFEs that we finalized for the Patient Access, Provider Access, Payer-
to-Payer, and Prior Authorization APIs.\113\
---------------------------------------------------------------------------

    \113\ For additional discussion of considerations related to 
granting an exception, please see 2024 CMS Interoperability and 
Prior Authorization final rule preamble (89 FR 8905-8906).
---------------------------------------------------------------------------

    In addition, we propose to amend the requirements in 45 CFR 
156.223(h)(1)(iii) to specify that QHP issuers on the FFEs, as part of 
a request for an exception from the Prior Authorization API 
requirements in 45 CFR 156.223(b), describe the current or proposed 
means of conducting prior authorization. Under the current requirement 
finalized in the 2024 CMS Interoperability and Prior Authorization 
final rule, QHP issuers on the FFEs that are applying for an exception 
must describe their current or proposed means of providing health 
information to providers. However, providing health information to 
providers does not describe the full scope of the Prior Authorization 
API. While part of the purpose of the Prior Authorization API is to 
make available to providers information about prior authorization 
requirements, it is also to facilitate prior authorization using 
bidirectional data exchanges between providers and payers. To align 
with the full scope and purpose of the Prior Authorization API, we 
believe that any QHP issuer on the FFE that applies for an exception 
should describe how they will facilitate prior authorization, not just 
how health information will be provided to providers.
    In summary, we request comment on our proposals in the CFR 
citations listed in Table 4, and specifically on the following:
     The proposal to remove the policy finalized in the 2024 
CMS Interoperability and Prior Authorization final rule that allows 
states with small FFS populations to request an exemption from CMS for 
the non-drug items and services Prior Authorization API requirements.
     The proposal that state Medicaid and CHIP FFS programs may 
request extensions to the finalized compliance date to implement the 
Prior Authorization API and the proposed compliance date to incorporate 
drugs covered under a medical benefit into the Prior Authorization API.
     The proposal that state Medicaid and CHIP FFS programs may 
request extensions and that QHP issuers on the FFEs may request an 
exception from the proposed requirement to support an unexpired version 
of the NCPDP standards that the Secretary has adopted in 45 CFR 
170.205(b), (c), or (u).
     The proposal to amend language in 45 CFR 
156.223(i)(1)(iii) to require that a QHP issuer on the FFEs seeking an 
exception from the Prior Authorization API requirements and/or proposed 
requirement to support an unexpired version of the NCPDP standards that 
the Secretary has adopted in 45 CFR 170.205(b), (c), or (u) to describe 
their current or proposed means of conducting prior authorization.
    In addition, we request comments on the following:
     Flexibilities and options that can be provided to state 
Medicaid and CHIP FFS programs eligible for an exemption and QHP 
issuers on the FFEs eligible for an exception that would reduce burden 
for the reasons outlined previously, while ensuring compliance with the 
proposed or adopted HIPAA transaction standards.

8. Statutory Authorities
a. Medicare Advantage
    Section 1856(b) of the Act directs the Secretary to establish 
regulatory standards for MA organizations that are consistent with and 
carry out Part C of the Medicare statute, including the provisions in 
section 1852 of the Act. Section 1852(c)(1)(G) of the Act requires that 
MA organizations disclose to their enrollees any rules regarding prior 
authorization, and section 1852(g)(1) of the Act requires MA 
organizations to have procedures for making timely determinations 
regarding whether an enrollee is entitled to receive a health service. 
Section 1857(e)(1) of the Act authorizes the addition of contract terms 
for contracts between the Secretary and an MA organization determined 
by the Secretary to be ``necessary and appropriate'' for the MA 
program. This broad authority encompasses the adoption of standards for 
electronic prior authorization, which are important for improving 
efficiency and reducing burdens in health care delivery.
    The Prior Authorization API is an electronic means for receiving 
and responding to requests for coverage determinations before the 
services are rendered or items furnished. The proposed requirement to 
incorporate drugs covered under a medical benefit that may require 
prior authorization into the Prior Authorization API is consistent with 
MA organizations' obligations under sections 1852(c)(1)(G) and 
1852(g)(1) of the Act. Pursuant to the Secretary's authority under 
sections 1856(b) and 1857(e)(1) of the Act, we are proposing to require 
MA organizations to expand the scope of the Prior Authorization API to 
incorporate drugs covered under a medical benefit.
    We propose additional requirements for MA organizations to ensure 
that providers have further information about drug prior authorization 
through the Prior Authorization API required under regulations in 42 
CFR 422.122(b). This proposed requirement would necessitate updating 
the Prior Authorization API with information about the coverage and 
documentation requirements for prior authorization of drugs covered 
under a medical benefit and responding to prior authorization requests 
for such drugs through the Prior Authorization API.
    We propose requiring MA organizations to expand the Prior 
Authorization API using recommended or updated implementation 
specifications discussed in section II.A. of this proposed rule. These 
implementation specifications are expected to improve the prior 
authorization process by addressing absences in providers' access to 
information about the prior authorization rules and documentation 
requirements for drugs. Under our proposal, the mandatory Prior 
Authorization API would communicate the coverage and documentation 
requirements for prior authorization for drugs covered under a medical 
benefit, indicating if authorization is required and what documentation 
is required to support an authorization request. This electronic API-
enabled access to information should improve timely access to care for 
patients by mitigating delays for necessary medications known to occur 
when a provider is trying to determine drug coverage or eligibility 
requirements or does not know what documents to submit to obtain prior 
authorization.
    If applicable, providers' burden may be reduced if they can submit 
a prior authorization request and access status and decision 
information for drugs through an MA organization's Prior Authorization 
API. The required Prior Authorization API can potentially improve the 
efficiency of the prior authorization process for drugs covered under a 
medical benefit as much as it does for non-drug items and services if 
the number of appeals, denials, and requests for additional 
documentation can be reduced.
    We believe this proposal to extend the scope of the Prior 
Authorization API to incorporate drugs covered under a medical benefit 
should contribute to program efficiency and effective operations and 
should be in the best interest of MA enrollees.
b. State Medicaid and CHIP
    For Medicaid, most of the proposals described in this section are 
authorized by sections 1902(a)(4), 1902(a)(8), and 1902(a)(19) of the 
Act. Section 1902(a)(4) of the Act requires that a state Medicaid plan 
provide such methods of administration as are found by the Secretary to 
be necessary for the proper and efficient operation of the state 
Medicaid plan. Section 1902(a)(8) of the Act requires states to ensure 
that Medicaid services are furnished with reasonable promptness to all 
eligible individuals, which may result in faster beneficiary access to 
services. Section 1902(a)(19) of the Act requires states to ensure that 
care and services under a Medicaid state plan are provided in a manner 
consistent with the simplicity of administration, which can result in 
more uniform IT regulations and standards that are in the best 
interests of the recipients. For Medicaid managed care, section 
1932(c)(1)(A) of the Act requires that states that contract with 
Medicaid MCOs develop and implement a quality assessment and 
improvement strategy that includes standards for access to care so that 
covered services are available within reasonable timeframes. CMS relies 
on our authority in section 1902(a)(4) of the Act to apply these 
standards for PIHPs and PAHPs.
    The proposals to incorporate drugs covered under a medical benefit 
into the Prior Authorization API and to improve electronic prior 
authorization for covered outpatient drugs by supporting the adopted 
version of the NCPDP SCRIPT standard by the Medicaid programs is 
supported by the sections of the Act referenced previously. For this 
proposal, CMS would rely on our authority in section 1902(a)(4) of the 
Act to adopt these standards for PIHPs and PAHPs. This would ensure 
that the same requirements apply to MCOs, PIHPs, and PAHPs.
    The proposal for state Medicaid FFS programs and Medicaid managed 
care plans to implement electronic prior authorization for drugs is 
expected to improve the efficiency and timeliness of the prior 
authorization process for Medicaid beneficiaries, providers, state 
Medicaid agencies, and Medicaid managed care plans by addressing 
inefficiencies that might exist in the process today. Support for the 
proposed FHIR and NCPDP standards could allow a provider to determine 
whether a prior authorization is required and the documentation 
requirements for that prior authorization request. The Prior 
Authorization API and NCPDP SCRIPT standard can improve the prior 
authorization process by making it more efficient, including by 
reducing the number of denials and appeals or eliminating requests for 
additional documentation. Those standards could--
     Enable providers to submit a complete prior authorization 
request faster and easier;
     Support more timely notice to the provider and beneficiary 
of the disposition of the prior authorization request; and
     Permit improved scheduling of services or filing appeals, 
depending on the decision.
    For CHIP, we are proposing these requirements under the authority 
of section 2101(a) of the Act, which sets forth that the purpose of 
Title XXI is to provide funds to states to provide child health 
assistance to uninsured, low-income children effectively and 
efficiently that is coordinated with other sources of health benefits 
coverage.
    We are proposing to require state CHIP FFS programs and CHIP 
managed

[[Page 19932]]

care entities to implement systems to support electronic prior 
authorization for all drugs to improve the prior authorization process 
for patients, providers, and payers. We believe these proposals should 
address deficiencies and inefficiencies that exist currently. Today, a 
payer's rules about when prior authorization is required for drugs and 
the documentation requirements are not necessarily easily accessible 
for providers. The Prior Authorization API and support for the proposed 
NCPDP standards should enable a provider to determine whether prior 
authorization is required for a drug, to access the documentation 
requirements, and to submit a prior authorization request 
electronically. While we expect providers to be the primary 
beneficiaries of these proposals, improving prior authorization for 
drugs could also serve the requirements in section 2101(a) of the Act 
that CHIP ensures access to coverage and coordinated care.
c. Qualified Health Plan Issuers on the Federally-facilitated Exchanges
    Section 1311(e)(1)(A) of the Affordable Care Act requires that 
Exchanges only certify plans as QHPs if they meet the requirements for 
certification promulgated by the Secretary under section 1311(c)(1) of 
the Affordable Care Act, while section 1311(e)(1)(B) of the Affordable 
Care Act provides discretion to certify QHPs if the Exchange determines 
that making such plans available is in the interests of qualified 
individuals and qualified employers in the state or states in which the 
Exchange operates.
    For QHP issuers on the FFEs, we are proposing to amend the QHP 
certification standard that we finalized in the 2024 CMS 
Interoperability and Prior Authorization final rule using the same 
authority under section 1311(e)(1) of the Affordable Care Act. These 
proposals would expand the use of specific technology and standards to 
promote efficiency and transparency in the prior authorization process 
for drugs, which should improve access to care for enrollees in QHPs 
offered by issuers on the FFEs by ensuring that the QHP issuers on the 
FFEs respond to prior authorization requests promptly through a 
modernized process and clearly explain their rationale in cases of 
denial. Our proposal to require that QHP issuers on the FFEs support 
electronic prior authorization for all covered drugs either through the 
Prior Authorization API as described in 45 CFR 156.223(b) or through an 
unexpired version of the NCPDP SCRIPT standard that the Secretary has 
adopted in 45 CFR 170.205(b), combined with the ability of QHP issuers 
on the FFEs to request an exception, is in the interest of qualified 
individuals and qualified employers because it balances the goals of 
ensuring access to health care with robust QHP issuer participation on 
the FFEs.
    Enrollees in QHPs on the FFEs may receive approved covered drugs 
more quickly when their providers can submit a prior authorization 
request electronically. These proposed requirements would allow 
providers to determine whether prior authorization is required for 
drugs, submit the necessary documentation, and receive an electronic 
response in real-time or near real-time. As we explained in the 2024 
CMS Interoperability and Prior Authorization final rule regarding the 
APIs required in that final rule (89 FR 8786), we believe that, with 
limited exceptions, certifying only health plans that support 
electronic prior authorization for all covered drugs and adhere to the 
other requirements described in this section of the preamble is in the 
interests of qualified individuals and qualified employers in the state 
or states in which a QHP issuer on the FFEs operates because of the 
opportunities for improvements in patient care. We encourage SBEs, 
including SBE-FPs, to consider whether a similar requirement should 
apply to issuers participating in their Exchanges.

C. Improving Communications and Decision Timeframes for Prior 
Authorizations

1. Background for Improving Prior Authorization Process
    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we described the impact of excessive wait times for prior 
authorization decisions on patients, providers, and payers (89 FR 8858 
and 8859). We discussed surveys, federal reports, and studies, 
including a multi-year survey conducted by the American Medical 
Association (AMA) about delays in care and medical risks to patients 
due to issues with prior authorization (89 FR 8859).\114\ Concerns 
about prior authorization processes have remained the same. According 
to a 2024 AMA report, 29 percent of physicians reported that prior 
authorization had led to a severe adverse event for a patient in their 
care, including hospitalization, permanent impairment, or death, and 94 
percent reported that prior authorization harmed patient clinical 
outcomes.\115\ In response to the 2022 CMS Interoperability and Prior 
Authorization proposed rule, many commenters stated that delays in 
responding to prior authorization requests for drugs significantly 
impacted patient care, health, and burden on providers (89 FR 8765).

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

    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we finalized specific process requirements for impacted payers to 
improve the prior authorization process for non-drug items and 
services. We established prior authorization decision timeframes for 
impacted payers other than QHP issuers on the FFEs (MA organizations, 
state Medicaid and CHIP FFS programs, Medicaid managed care plans, and 
CHIP managed care entities) and required that, when denying a prior 
authorization request for non-drug items and services, impacted payers 
respond to the requesting provider with a specific reason for the 
denial (89 FR 8897). Shortening and standardizing timeframes for prior 
authorization decisions across programs improves access to health care 
and can mitigate the negative impacts of delays, particularly for 
individuals with chronic or complex conditions. The term ``denial'' 
means that the payer has refused to authorize coverage for a 
recommended medical treatment, procedure, or medication. Payers deny 
coverage for various reasons, such as a determination that the service 
or medication is not medically necessary or does not meet their 
coverage criteria. Requesting providers need to clearly understand the 
reason for denial so that additional information can be provided or 
alternative care options can be considered.
    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we also finalized requirements on impacted payers to publicly 
report certain prior authorizations metrics for non-drug items and 
services annually beginning in 2026.\116\ By sharing appropriate data, 
payers can build trust with their patients and providers and showcase

[[Page 19933]]

their commitment to improving services. Beyond information about which 
services require prior authorization and the requirements for approval, 
greater transparency about payer performance on denials, timeframes, 
and volumes could be helpful for the public. Such reporting improves 
accountability and can identify opportunities for improvement.
---------------------------------------------------------------------------

    \116\ See 42 CFR 422.122(c) for MA organizations and applicable 
integrated plans, 42 CFR 440.230(e)(3) for state Medicaid FFS 
programs, 42 CFR 457.732(c) for state CHIP FFS programs, 42 CFR 
438.210(f) for Medicaid managed care plans, through existing cross 
reference to 42 CFR 438.210 in 42 CFR 457.1230(d) for CHIP managed 
care entities, and 45 CFR 156.223(c) for individual market QHP 
issuers on the FFEs.
---------------------------------------------------------------------------

    The proposals in this proposed rule to extend our technical and 
process requirements for prior authorization to all drugs should 
improve patients' access to services. We intend these proposals to 
create more unified processes for providers to request and receive 
prior authorization for drugs. Such standardization and consistency 
should allow providers to spend more time on patient care and less time 
on administrative tasks and paperwork. Additionally, standardized 
processes could reduce wait times and resubmissions and result in more 
efficient and accurate decision-making.
2. Proposed Requirement To Include a Specific Reason for Denial in 
Response to Prior Authorization Requests for All Drugs
a. Background
    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we finalized a requirement that, beginning in 2026, impacted 
payers must provide a specific reason for denial in their response to a 
provider's prior authorization request for non-drug items and services, 
regardless of the method used to communicate the prior authorization 
request or decision.\117\ We are now proposing to add the same 
requirements for denied prior authorizations for all drugs for impacted 
payers that are not already subject to such a requirement. Throughout 
the 2022 CMS Interoperability and Prior Authorization proposed rule (87 
FR 76238) and the 2024 CMS Interoperability and Prior Authorization 
final rule (89 FR 8758), we described opportunities to improve the 
prior authorization process, specifically where better communication 
between payers and providers could mitigate confusion about the status 
of a prior authorization and why a request was denied. Although prior 
authorization has a role in the health care system, denying services 
that do not meet the payer's internal coverage or utilization criteria 
or do not meet regulatory or statutory requirements should not 
adversely impact the health or well-being of the patient. If a denial 
is ineffectively communicated, then it could cause a patient to delay 
or abandon treatment.
---------------------------------------------------------------------------

    \117\ See 42 CFR 422.122(a) for MA organizations and applicable 
integrated plans, 42 CFR 431.80(a) for state Medicaid FFS programs, 
42 CFR 457.732(a) for state CHIP FFS programs, through cross 
reference to 42 CFR 431.80(a) in 42 CFR 438.242(b)(8) for Medicaid 
managed care plans, through cross reference to 42 CFR 438.242 in 42 
CFR 457.1233(d) for CHIP managed care entities, and 45 CFR 
156.223(a) for individual market QHP issuers on the FFEs.
---------------------------------------------------------------------------

    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we explained that payers deny prior authorizations for a variety 
of reasons, including because the payer does not consider the items to 
be medically necessary, the patient exceeded limits on allowable 
covered care, or documentation to support the request was missing or 
inadequate (89 FR 8872). The reasons for denying prior authorizations 
for drugs may be similar. Health plan formularies are lists of generic 
and brand-name drugs covered by a health plan and may include drug 
tiering information. If prior authorization is denied because of a 
payer's formulary or utilization management policies and that is not 
clearly communicated, then the provider cannot effectively act on 
behalf of the patient. When a payer provides a specific reason for a 
denial, a provider can take appropriate actions such as resubmitting 
the request with updated information, appealing the decision, or 
identifying alternative drugs or treatments. Payers send denials 
through various channels--electronically, by mail, via portal, or by 
fax. When doing so, they often use proprietary codes or narrative text 
to communicate the reasons for denial. For some payers, the process of 
communicating denials remains both inefficient and inconsistent. The 
result is that providers may not have timely, clear direction on the 
next steps for providing appropriate care for their patients after a 
denied prior authorization request.
b. Existing Requirements To Communicate With Providers About Denied 
Prior Authorization Requests for Drugs
    As described in the 2024 CMS Interoperability and Prior 
Authorization final rule, some impacted payers are required by existing 
federal laws and regulations to notify providers or patients when the 
payer denies or makes an adverse decision on a prior authorization 
request (89 FR 8874-8876). We are not proposing to alter or replace 
existing requirements for payers to notify patients, but to add 
requirements to ensure a specific reason for denial is communicated to 
providers. In addition to the existing program notification 
requirements, communicating specific reasons for denial increases 
transparency, reduces burden, and improves efficiencies for both payers 
and providers.
    Under existing regulations, an MA organization must notify the 
enrollee (and the prescribing physician or other prescriber involved, 
as appropriate) of its determination on a request for a Part B drug as 
expeditiously as the enrollee's health condition requires but no later 
than 72 hours after receiving a standard request and no later than 24 
hours after receiving an expedited request.\118\ When a request for a 
Part B drug is denied, MA organizations must provide the specific 
reasons for the denial along with certain other information, such as 
how to request an appeal.\119\ CMS provides a standardized form \120\ 
that MA organizations must use, which captures a specific rationale of 
why the item, service, or Part B drug was denied, including a 
description of the applicable coverage rule or applicable plan policy 
(for example, the Evidence of Coverage provision) upon which the action 
was based and a specific explanation about what information is needed 
to approve coverage, if applicable. Given that existing regulations 
require MA organizations to notify the enrollee and the prescriber, as 
appropriate, of a decision on a Part B drug request, we are not 
proposing any changes related to the notice requirements for a prior 
authorization decision by an MA organization in this rule. Similar 
notice requirements, including a reason for denial, exist for Part D 
sponsors making prior authorization decisions.\121\ Standardized MA and 
Part D denial notices, which plans must send to enrollees, require a 
specific reason for the denial and the following language: ``Share a 
copy of this decision with your doctor and discuss next steps. If your 
doctor asked for coverage on your

[[Page 19934]]

behalf, we already sent them a copy of this denial notice.'' \122\

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

    Similarly, Medicaid managed care plans and CHIP managed care 
entities must notify the requesting provider and give the beneficiary 
written notice of any decision by the plan to deny a service 
authorization request or to authorize a service in an amount, duration, 
or scope that is less than requested.\123\ As specified in 42 CFR 
438.242(b)(8), by the rating period beginning on or after January 1, 
2026, Medicaid managed care plans must communicate a specific reason 
for any denials to the provider, regardless of the method used to 
communicate that information, for prior authorization requests for non-
drug items and services.\124\ These requirements also apply to CHIP 
managed care entities by cross reference.\125\
---------------------------------------------------------------------------

    \123\ See 42 CFR 438.210(c) and 438.242(b)(8) for Medicaid

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

    While 45 CFR 156.223(a) requires QHP issuers on the FFEs to include 
a specific reason for the denial of a prior authorization request to 
the provider, this requirement explicitly excludes prescription drugs.
c. Proposed Requirement To Include a Specific Reason for Denial to 
Providers When Denying Prior Authorization of All Drugs for State 
Medicaid and CHIP Fee-for-Service Programs, Medicaid Managed Care 
Plans, CHIP Managed Care Entities, and Qualified Health Plan Issuers on 
the Federally-facilitated Exchanges
    We propose that beginning October 1, 2027, state Medicaid and CHIP 
FFS programs, Medicaid managed care plans, CHIP managed care entities, 
and QHP issuers on the FFEs be required to provide a specific reason to 
providers when denying a prior authorization request for drugs, 
regardless of the method used to send the prior authorization request 
or decision. This proposal is an effort to improve the communication 
between those impacted payers and providers when they deny a prior 
authorization request for drugs. This proposal would align with the 
requirement finalized in the 2024 CMS Interoperability and Prior 
Authorization final rule that impacted payers send to providers a 
specific reason for denying a prior authorization request for non-drug 
items and services.\126\ We now propose to apply that same denial 
notice requirement to state Medicaid and CHIP FFS programs, Medicaid 
managed care plans, CHIP managed care entities, and QHP issuers on the 
FFEs for prior authorizations for drugs. This proposed change should 
lead to those payers providing more transparent communication in their 
decision-making, allowing providers to address any deficiencies in the 
request or consider alternative treatments.
---------------------------------------------------------------------------

    \126\ See 42 CFR 422.122(a) for MA organizations and applicable 
integrated plans, 42 CFR 431.80(a) for state Medicaid FFS programs, 
42 CFR 457.732(a) for state CHIP FFS programs, through cross 
reference to 42 CFR 431.80(a) in 42 CFR 438.242(b)(8) for Medicaid 
managed care plans, through cross reference to 42 CFR 438.242 in 42 
CFR 457.1233(d) for CHIP managed care entities, and 45 CFR 
156.223(a) for individual market QHP issuers on the FFEs.
---------------------------------------------------------------------------

    The content of the response should include a specific reason for 
denying a prior authorization request for drugs that helps a provider 
to understand why the request was denied and what actions must be taken 
to resubmit or appeal the decision. A specific reason for denial could 
include information about the specific plan coverage criteria on which 
the denial is based, why documentation did not support the medication 
or prescription, or why the drug is not deemed necessary. This proposal 
could improve the current processes and reduce manual effort and costs 
by increasing the likelihood that providers whose prior authorization 
request for drugs is denied have all the information they need to 
decide the next steps to care for the patient, including whether and 
how to appeal the denial. We are proposing an October 1, 2027 effective 
date for this proposal, as these protections are important to patients.
    This proposal does not affect existing patient notice requirements 
for state Medicaid and CHIP FFS programs and QHP issuers on the FFEs. 
State Medicaid and CHIP FFS programs are required to provide a 
beneficiary with timely and adequate written notice of a ``denial or 
change in benefits and services.'' \127\ In case of an adverse benefit 
determination, QHP issuers on the FFEs must include in their notice to 
enrollees certain information, including the reason(s) for the adverse 
benefit determination, a denial code and its meaning, and a description 
of the QHP issuer on the FFEs' standard that was used in the 
denial.\128\ Like the requirement that we finalized in the 2024 CMS 
Interoperability and Prior Authorization final rule for non-drug items 
and services, our proposed requirement should ensure that providers who 
submit prior authorization requests for drugs receive information 
directly from impacted payers regarding an adverse prior authorization 
determination, which should expedite their ability to appeal the 
determination or provide additional information if needed.

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

    In addition to these new requirements, we are proposing to 
reorganize 42 CFR 438.210(c) and 42 CFR 438.242 to improve readability. 
This proposal maintains existing program requirements for non-drug 
items and services while proposing these new requirements for Medicaid 
managed care plans to provide specific denial reasons for drug prior 
authorization requests.
    In summary, we request comment on our proposals in the CFR 
citations listed in Table 6, and specifically on the following:
     The proposal to require state Medicaid and CHIP FFS 
programs, Medicaid managed care plans, CHIP managed care entities, and 
QHP issuers on the FFEs to communicate to providers a specific reason 
for denying a prior authorization request for any drugs, regardless of 
the method used to send the prior authorization request or decision.
     The proposed October 1, 2027 compliance date for state 
Medicaid and CHIP FFS programs, Medicaid managed care plans, CHIP 
managed care entities, and QHP issuers on the FFEs.
     The proposed structural changes to 42 CFR 438.210(c) and 
42 CFR 438.242 to improve readability.
3. Prior Authorization Decision Timeframes
a. Background
    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we finalized requirements for MA organizations, state Medicaid 
and CHIP FFS programs, Medicaid managed care plans, and CHIP managed 
care entities to make prior authorization decision requests on non-drug 
items and services as expeditiously as a patient's health condition 
requires but no later than 7 calendar days after receiving a standard 
request and no later than 72 hours after receiving an expedited 
request, effective in 2026 (89 FR 8897). However, we did not propose or 
finalize those requirements for QHP issuers on the FFEs, in part 
because existing regulations in 45 CFR 147.136 establish timelines for 
all non-grandfathered

[[Page 19935]]

group health plans and health insurance issuers offering individual and 
group health insurance coverage (``plans and issuers'') to notify 
claimants, participants, beneficiaries, and enrollees (patients) of 
prior authorization (referred to in those regulations as a ``pre-
service'') decisions (89 FR 8879). Specifically, 45 CFR 
147.136(b)(3)(i) generally requires plans and issuers to meet the 
requirements of the claims and appeals procedures applicable to group 
health plans in 29 CFR 2560.503-1, as if the coverage were a group 
health plan. Under those requirements, QHP issuers on the FFEs must 
notify patients of a plan's benefit determination on a prior 
authorization request as expeditiously as a patient's health condition 
requires but no later than 15 days after a standard request and as soon 
as possible, taking into account the medical exigencies, but no later 
than 72 hours for expedited requests (referred to in those regulations 
as ``urgent care'' claims). Notably, these timeframes apply to non-drug 
items and services, as well as drugs. While neither 45 CFR 
147.136(b)(3) nor 29 CFR 2560.503-1 require plans and issuers to notify 
the requesting provider of a prior authorization decision, when they 
do, HHS presumes that they do so within the same timeframes that they 
are required to notify patients. As a result, beginning in 2026, QHP 
issuers on the FFEs effectively have longer to provide notification of 
a decision on a standard prior authorization request for non-drug items 
and services (a maximum of 15 days) as compared to other impacted 
payers (a maximum of 7 days).\129\ In contrast, QHP issuers on the FFEs 
effectively have the same amount of time to provide notification of a 
decision on a standard prior authorization request for non-drug items 
and services as other impacted payers (a maximum of 72 hours). Finally, 
in both cases, as noted, there is no regulatory requirement that QHP 
issuers on the FFEs notify providers of any prior authorization 
decision.
---------------------------------------------------------------------------

    \129\ As noted above, effective in 2026, MA organizations, state 
Medicaid and CHIP FFS programs, Medicaid managed care plans, and 
CHIP managed care entities must notify claimants and providers of 
prior authorization decisions on non-drug items and services no 
later than 7 calendar days for standard requests and no later than 
72 hours for expedited requests
---------------------------------------------------------------------------

    In addition to the requirements for non-drug items and services, MA 
organizations, state Medicaid FFS programs, Medicaid managed care 
plans, and CHIP managed care entities have existing decision timeframe 
requirements for prior authorization of certain drugs. MA organizations 
must notify the enrollee (and the prescribing physician or other 
prescriber involved, as appropriate) of a determination regarding 
coverage of a Part B drug as expeditiously as the enrollee's health 
condition requires, but no later than 72 hours after receiving the 
standard request and no later than 24 hours after receiving the 
expedited request.\130\ Similarly, Part D sponsors, including MA-PDs, 
have the same requirements for prior authorization decisions on Part D 
drugs (with the possibility of an extension).\131\ The Part D sponsor 
must notify the enrollee (and the prescribing physician or other 
prescriber involved, as appropriate) of its determination as 
expeditiously as the enrollee's health condition requires, but no later 
than 72 hours after receiving the standard request and no later than 24 
hours after receiving the expedited request. Given the existing prior 
authorization decision timeframe requirements for Part B and Part D 
drugs, we do not believe that additional proposals for MA organizations 
or Part D sponsors are necessary or appropriate at this time. However, 
we request comment on whether there are any drugs payable under Part A 
that are not included as part of a larger bundle of inpatient services 
to which the timeframe to make prior authorizations decisions should 
apply for MA organizations. If so, we would consider finalizing a 
policy to ensure that all drugs that require prior authorization have 
appropriate decision timeframes.
---------------------------------------------------------------------------

    \130\ See 42 CFR 422.568(b)(3) and 42 CFR 422.572(a)(2).
    \131\ See 42 CFR 423.568(b) and 42 CFR 423.572(a).
---------------------------------------------------------------------------

    State Medicaid FFS programs, Medicaid managed care plans, and CHIP 
managed care entities also have existing decision timeframe 
requirements for covered outpatient drugs.\132\ Specifically, state 
Medicaid FFS programs, Medicaid managed care plans, and CHIP managed 
care entities must respond to a prior authorization request for a 
covered outpatient drug within 24 hours of the request and dispense at 
least a 72-hour supply of the drug in emergencies. However, there is no 
requirement specific to drugs for state CHIP FFS programs. Instead, 
state CHIP FFS programs must adhere to the general decision-making 
timeframe, which mandates that prior authorization decisions be made in 
accordance with the medical needs of the patient within 14 days after 
receiving a request for services (beginning on January 1, 2026, the 
timeframe will be 7 calendar days for standard requests and 72 hours 
for expedited requests).\133\
---------------------------------------------------------------------------

    \132\ See section 1927(d)(5)(A) of the Act for state Medicaid 
FFS programs, 42 CFR 438.210(d)(3) and 42 CFR 438.3(s)(6) for 
Medicaid managed care plans, and through cross reference to 42 CFR 
438.210(d)(3) in 42 CFR 457.1230(d) for CHIP managed care entities.
    \133\ See 42 CFR 457.495(d).
---------------------------------------------------------------------------

    As discussed in sections II.C.3.c. and II.C.3.d. of this proposed 
rule, we are now requesting information on whether there are gaps in 
timeframe requirements for some drugs and if there are we are proposing 
to apply the prior authorization decision timeframes for non-drug items 
and services outlined in the 2024 CMS Interoperability and Prior 
Authorization final rule to that subset of drugs for which there are 
not already established prior authorization timeframes. This would 
apply to both state Medicaid FFS programs and Medicaid managed care 
plans. We are also proposing to modify state CHIP FFS programs' 
decision-making timeframes for the prior authorization of drugs comport 
with section 1927(d)(5)(A) of the Act to align with the requirements 
for those programs.
b. Prior Authorization Decision Timeframes for Qualified Health Plan 
Issuers on the Federally-facilitated Exchanges
    In response to the 2022 CMS Interoperability and Prior 
Authorization proposed rule, many commenters disagreed with excluding 
QHP issuers on the FFEs from the shortened timeframe requirements and 
asked that CMS reconsider the exclusion. Commenters stated it would be 
more consistent and equitable for CMS to apply the same timeframe 
requirements for standard prior authorization decisions for all 
impacted payers (89 FR 8880). Commenters stated that patients covered 
by these plans should be entitled to the same protections as those 
covered by other impacted payers, and that excluding QHP issuers on the 
FFEs could negatively affect patients by delaying access to care based 
only on the type of insurance they have. One commenter stated that they 
did not believe that shortening the prior authorization decision 
timeframe for QHP issuers on the FFEs from a 15 day response time for 
standard requests to 7 days would cause an undue burden to those plans. 
We also received many comments requesting CMS consider adding 
additional standards to the prior authorization process to address the 
adverse effects of delays on patients and providers (89 FR 8859). 
Multiple commenters wrote that CMS should apply even shorter prior 
authorization decision timeframes to QHP issuers on the FFEs, such as 
72 hours for standard

[[Page 19936]]

requests and 24 hours for expedited requests.
    In response to the comments received, we stated that we would 
evaluate opportunities for future rulemaking to alleviate provider 
burdens and mitigate delays associated with prior authorization (89 FR 
8859). We are aware that a growing number of states have passed laws to 
reduce prior authorization decision timeframes, require technical 
standards, limit procedural justifications for denials, tie decisions 
to clinical criteria, and increase transparency.\134\ In addition to 
public comments that expressed concerns that patients experience 
delayed or deferred care because of complex prior authorization 
processes, recent research has suggested that these concerns 
disproportionately impact those with chronic conditions and mental 
health care needs.\135\

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

    Hence, we are now proposing, in 45 CFR 156.223(i)(1)(i), that 
beginning October 1, 2027 in response to a request for prior 
authorization for non-drug items and services, QHP issuers on the FFEs 
must notify the requesting provider of their decision as expeditiously 
as a patient's health condition requires but no later than 7 days after 
receiving a standard prior authorization request and no later than 72 
hours after receiving an expedited prior authorization request.
    We also propose, in 45 CFR 156.223(i)(1)(ii), that beginning 
October 1, 2027 in response to a prior authorization request for any 
drug, QHP issuers on the FFEs must notify a requesting provider of 
their decision as expeditiously as the enrollee's health condition 
requires, but no later than 72 hours after receiving a standard prior 
authorization request and no later than 24 hours after receiving an 
expedited prior authorization request. These are similar to the 
timeframes for prior authorization decisions for drugs that we propose 
for other impacted payers in this proposed rule. The proposed 
timeframes to require QHP issuers on the FFEs to notify the requesting 
provider of a prior authorization decision would be new; that is, there 
is currently no requirement for QHP issuers on the FFEs to notify 
providers of a prior authorization decision within any specific period 
of time. This proposal would not change existing prior authorization 
notification requirements in 45 CFR 147.136 for patients but would 
create a new requirement for QHP issuers on the FFEs to notify the 
requesting provider of a prior authorization decision within a specific 
timeframe based on the nature of the request, and these timeframes 
would generally be shorter than the maximum amount of time that QHP 
issuers on the FFEs have to notify patients regarding standard prior 
authorization requests under existing regulations in 45 CFR 
147.136.\136\
---------------------------------------------------------------------------

    \136\ Consistent with the treatment of the requirement that 
payers provide the specific reason for denying a prior authorization 
request in the payer's response to the provider established in the 
2024 CMS Interoperability and Prior Authorization final rule, the 
burden associated with notifying the requesting provider of the 
health plan's prior authorization determination is considered usual 
and customary as the disclosure is integral to the business practice 
and function of the health plan. Therefore, we have identified the 
burden associated with communicating a prior authorization decision 
as a usual and customary business practice that does not require a 
burden calculation pursuant to 5 CFR 1320.3(b)(2).
---------------------------------------------------------------------------

    Establishing a new requirement for QHP issuers on the FFEs to 
notify providers of prior authorization decisions on non-drug items and 
services and drugs, and aligning those timelines with current and 
proposed timelines for other impacted payers, could improve patient 
care and minimize administrative burden for providers who would be able 
to expect prior authorization decisions within the same timeframe from 
all impacted payers. We are not proposing to shorten the timeframes for 
QHP issuers on the FFEs to notify patients of prior authorization 
decisions as established in 45 CFR 147.136(b)(3); however, we recognize 
that QHP issuers on the FFEs may voluntarily adopt shorter patient 
notification timeframes that align with the proposed provider 
notification timeframes to minimize administrative burden. Therefore, 
this proposal may result in faster notification for patients than is 
required by 45 CFR 147.136(b)(3) and may result in QHP issuers on the 
FFEs notifying patients more quickly than plans and issuers subject to 
45 CFR 147.136(b)(3), including issuers on SBEs.
    We expect that the proposed timeframes for notifying providers 
would be feasible for QHP issuers on the FFEs given the notification 
functionality of the Prior Authorization API and NCPDP standards that 
we are proposing QHP issuers on the FFEs to support for electronic 
prior authorization. Those standards support direct electronic 
communications between payers and providers about prior authorizations. 
In addition, that available technology can accelerate the decision-
making itself and we are of the view that QHP issuers on the FFEs 
should be part of this trend in process improvement.
    As noted above, we are proposing that QHP issuers on the FFEs 
notify the requesting provider ``as expeditiously as the enrollee's 
health condition requires,'' subject to the proposed time limits, which 
is the standard for non-drug items and services used by MA 
organizations,\137\ Part D sponsors,\138\ Medicaid,\139\ and CHIP.\140\ 
We are proposing that, in determining what an enrollee's health 
condition requires, QHP issuers on the FFEs must abide by the same 
requirement to make decisions in accordance with established accepted 
standards of medical practice in assessing an individual's medical 
condition, and we solicit comment on whether any other language in 
regulation or in sub-regulatory guidance is necessary to ensure that 
QHP issuers on the FFEs adhere to this standard.

    \140\ See 42 CFR 457.495(d), using the phrase ``In accordance

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

    We also propose, in 45 CFR 156.223(i)(2), that for purposes of 45 
CFR 156.223(i)(1), a standard prior authorization request has the 
meaning given in 29 CFR 2560.503-1(m)(2) to a ``pre-service claim'' and 
an expedited prior authorization request has the meaning given in 29 
CFR 2560.503-1(m)(1) to a ``claim involving urgent care,'' as 
determined by the attending provider, and the issuer shall defer to 
such determination of the attending provider. By relying on existing 
definitions, we seek to maintain consistency across requirements 
related to prior authorization for QHP issuers on the FFEs.
    We also propose, in 45 CFR 156.223(i)(3)(i), that the QHP issuer on 
the FFEs may extend the timeframes to notify the requesting provider of 
a prior authorization decision by up to 14 calendar days under any of 
the following circumstances: (1) if the provider requests the 
extension; (2) the extension is justified and in the provider's or 
enrollee's interest because the QHP issuer on the FFEs needs additional 
medical evidence from another provider or the enrollee in order to 
issue a decision; or (3) the extension is justified due to 
extraordinary, exigent, or other non-routine circumstances and is in 
the provider's or enrollee's interest. If extended, the QHP issuer on 
the FFEs

[[Page 19937]]

would be required to notify the provider of its determination as 
expeditiously as the enrollee's health condition requires, but no later 
than upon expiration of the extension. We also propose to require, in 
45 CFR 156.223(i)(3)(ii), that when the QHP issuer on the FFEs extends 
the timeframe, it must notify the requesting provider in writing of the 
reasons for the extension and inform the provider of the right to file 
an expedited grievance if the provider disagrees with the QHP issuer on 
the FFE's decision to grant an extension. This language is similar to 
the corresponding provision that CMS finalized in the 2024 
Interoperability and Prior Authorization final rule. We believe it is 
appropriate for QHP issuers on the FFEs as well, but solicit comment on 
whether that is the case or if it should be amended.
    In summary, we request comment on our proposals in the CFR 
citations listed in Table 6, and specifically on the following:
     The proposal to require QHP issuers on the FFEs to provide 
notice to the requesting provider of prior authorization decisions as 
expeditiously as the enrollee's health condition requires, but no later 
than 7 calendar days after receiving a standard prior authorization 
request for non-drug items and services and as expeditiously as the 
enrollee's health condition requires, but no later than 72 hours after 
receiving an expedited request for non-drug items and services.
     The proposal to require QHP issuers on the FFEs to provide 
notice to the requesting provider of prior authorization decisions as 
expeditiously as the enrollee's health condition requires, but no later 
than 72 hours after receiving a standard prior authorization request 
for drugs and as expeditiously as the enrollee's health condition 
requires, but no later than 24 hours after receiving an expedited 
request for drugs.
     The proposal that QHP issuers on the FFEs may extend the 
timeframes to notify the requesting provider of a prior authorization 
decision by up to 14 calendar days under certain circumstances, and the 
QHP issuers on the FFEs must notify the requesting provider in writing 
of the reasons for the delay and inform the provider of the right to 
file an expedited grievance if the provider disagrees with the QHP 
issuer on the FFEs' decision to grant an extension.
     The proposal that for purposes of 45 CFR 156.223(i)(1), a 
standard prior authorization request has the meaning given in 29 CFR 
2560.503-1(m)(2) to a ``pre-service claim'' and an expedited prior 
authorization request has the meaning given in 29 CFR 2560.503-1(m)(1) 
to a ``claim involving urgent care'' for QHP issuers on the FFEs.
     The proposed October 1, 2027 compliance date.
    In addition, we request comments on the following:
     Whether requiring QHP issuers on the FFEs to provide 
notice to requesting providers of prior authorization decisions in a 
shorter timeframe than they are currently required to provide notice to 
patients of prior authorization decisions is sufficient to improve 
enrollees' care, or if CMS should consider also applying shorter 
timeframes for notification to patients, as well.
     Whether there would be burden due to the different 
timeframes for QHP issuers on the FFEs to notify a requesting provider 
of a prior authorization decision and to notify participants, 
beneficiaries, and enrollees of prior authorization decisions, and how 
we could potentially alleviate that burden.
     Whether we should finalize shorter timeframes for QHP 
issuers on the FFEs to notify the requesting provider of prior 
authorization requests for drugs, specifically, 24 hours for all 
requests (standard or expedited), to align with the existing 
requirements for state Medicaid FFS programs, Medicaid managed care 
plans, and CHIP managed care entities, and our proposal for state CHIP 
FFS programs.
     Whether the requirement to make decisions as 
``expeditiously as the enrollee's health condition requires'' is 
appropriate, or whether additional or alternative language or sub-
regulatory guidance is necessary to help ensure impacted payers make 
timely decisions and for consistency with existing decision timeframes 
in 45 CFR 147.136(b)(3) and 29 CFR 2560.503-1(f).
     Whether QHP issuers' parent organizations that participate 
in multiple CMS-regulated programs, such as MA organizations or 
Medicaid managed care plans, already have experience responding to 
prior authorization requests more quickly than it is currently required 
by existing market wide rules that they can leverage to improve 
processes for their QHPs offered on the FFEs.
     Whether QHP issuers on the FFEs' plan management systems 
can readily distinguish between a policy applicable to a QHP offered on 
an FFE, a policy applicable to off-Exchange individual or small group 
coverage, or a QHP issuer in an SBE.
c. Prior Authorization Decision Timeframes for Drugs That Are Not 
Covered Outpatient Drugs for State Medicaid Fee-for-Service Programs, 
Medicaid Managed Care Plans, and CHIP Managed Care Entities
    As discussed previously, section 1927(d)(5)(A) of the Act 
establishes a 24-hour timeframe for state Medicaid FFS programs to 
respond to requests for prior authorization of covered outpatient drugs 
for which FFP is available. However, that timeframe may not apply to 
all drugs that are covered by states for which states receive FFP. In 
the 2022 CMS Interoperability and Prior Authorization proposed rule, 
which addressed prior authorization decision timeframes for non-drug 
items and services, CMS received comments indicating that drugs should 
have been included in the prior authorization timeframe policies and 
that gaps exist regarding timeframe requirements on prior 
authorizations for certain drugs. Given that covered outpatient drugs 
already have an established statutory timeframe for prior authorization 
pursuant to section 1927 of the Act, we seek to address the comments 
concerning a possible gap in prior authorization timeframes for a 
subset of drugs which are not covered outpatient drugs. In addition, to 
address concerns by commenters, we explain the prior authorization 
decision timeframes for drugs that otherwise meet the definition of 
covered outpatient drugs in section 1927(k)(2) of the Act but are 
excluded from the definition of covered outpatient drugs due to meeting 
the criteria in the limiting definition of covered outpatient drug in 
section 1927(k)(3) of the Act.
    Section 1927(k)(3) of the Act limits the term ``covered outpatient 
drug'' to exclude any drug, biological product, or insulin provided as 
part of, or as incident to and in the same setting as, certain services 
(and for which payment may be made under that subchapter as part of 
payment for those services and not as direct reimbursement for the 
drug).\141\ To the extent that state Medicaid and CHIP programs cover 
and impose prior authorization requirements on these drugs that are not 
covered outpatient drugs, we believe the same decision timeframe 
requirements that

[[Page 19938]]

apply to prior authorization for the non-drug items and services should 
apply to a drug that is provided incident to those services. Therefore, 
non-covered outpatient drugs that meet the limiting definition in 
section 1927(k)(3) of the Act should align with the timeframe 
requirements for non-drug items and services, which is 7 calendar days 
for standard requests and 72 hours for expedited requests. We believe 
it is most appropriate to align the prior authorization decision 
timeframe for a drug that meets the limiting definition in section 
1927(k)(3) of the Act with the services it is provided as part of, or 
incident to. We believe this will ensure a prior authorization decision 
is rendered for the drug and non-drug items and services within the 
same timeframe as opposed to having the drug reviewed under a different 
timeframe than the remainder of the service with which it is bundled 
with.
---------------------------------------------------------------------------

    \141\ The services listed in section 1927(k)(3) of the Act are: 
inpatient hospital services; hospice services; dental services, 
except that drugs for which the State plan authorizes direct 
reimbursement to the dispensing dentist are covered outpatient 
drugs; physicians' services; outpatient hospital services; nursing 
facility services and services provided by an intermediate care 
facility for the mentally retarded; other laboratory and x-ray 
services; and renal dialysis.
---------------------------------------------------------------------------

    One example of this subset of drugs are those that are administered 
in an inpatient hospital setting. Drugs administered in an inpatient 
setting are typically paid for as part of a bundled payment, which 
includes a variety of items, services, and drugs. Under that payment 
model, when prior authorization is required, it is typically submitted 
as a bundle and drugs are not separated from non-drug items and 
services; drugs and non-drug items and services are reviewed under the 
same prior authorization request and therefore same timeframe. In those 
situations, we do not believe there is a need for a separate timeframe 
for the drug component of the prior authorization; the prior 
authorization timeframes established in the 2024 CMS Interoperability 
and Prior Authorization final rule would apply to the entirety of the 
prior authorization request.
    In addition, we request comment on whether there are categories of 
non-covered outpatient drugs for which it would be more appropriate to 
finalize a decision timeframe that aligns with the statutory 
requirement for covered outpatient drugs at section 1927(d)(5)(A) of 
the Act. It is unclear whether there are drugs (that are not covered 
outpatient drugs) for which states require prior authorization and for 
which 24 hours would be the appropriate decision timeframe, rather than 
the longer decision timeframe for non-drug items and services. As 
stated, we do not desire to create different timeframes for prior 
authorization decisions for drugs versus non-drug items and services 
for which reimbursement and prior authorization requests are bundled. 
However, we also want to address any gaps for standalone prior 
authorization requests for drugs that either do not have an existing 
prior authorization decision timeframe requirement, or for which the 
prior authorization decision timeframe is misaligned with our other 
proposals in this proposed rule.
    We propose that if commenters identify gaps in the decision 
timeframe requirements for drugs, we would apply the same requirements 
to Medicaid MCOs, PIHPs, and PAHPs by amending 42 CFR 438.210 and CHIP 
managed care entities by the existing cross reference to 42 CFR 438.210 
in 42 CFR 457.1230(d).
    We are proposing an October 1, 2027 compliance date for these 
proposals for state Medicaid FFS programs, Medicaid managed care plans, 
and CHIP managed care entities.
    In summary, we request comments on the following:
     The scope of drugs for which we are proposing these prior 
authorization requirements. Are there additional drugs that currently 
have no established prior authorization timeframe requirements for 
which such timeframes should be established? Is there a need to apply 
prior authorization timeframe requirements to the scope of drugs 
proposed in this rule? Are there other types of drugs for which we 
should finalize a requirement that aligns with the 24 hour timeframe 
established for covered outpatient drugs by section 1927(d)(5)(A) of 
the Act?
     The proposed October 1, 2027 compliance date for state 
Medicaid FFS programs, Medicaid managed care plans, and CHIP managed 
care entities.
     Whether we should consider future rulemaking to propose a 
requirement for MA organizations to respond to all prior authorization 
requests for drugs no later than 24 hours to align with the Medicaid 
and CHIP requirements for covered outpatient drugs.
     Whether there are any drugs payable under Medicare Part A 
that are not included as part of a larger bundle of inpatient services 
to which the timeframe to make prior authorizations decisions should 
apply for MA organizations.
d. Prior Authorization Decision Timeframes for Prescription Drugs for 
State CHIP Fee-for-Service Programs
    To align with the existing requirements for state Medicaid FFS 
programs, Medicaid managed care plans, and CHIP managed care entities 
requirements for covered outpatient drugs, as well as the proposals 
described in section II.C.3.c. of this proposed rule, we propose to 
shorten the timeframe for state CHIP FFS programs to make prior 
authorization decisions on prescription drugs for which the state 
receives FFP, as described in section 2110(a)(6) of the Act. As noted 
previously, the current requirement is the same 7 days for standard 
requests and 72 hours for expedited requests as for non-drug items and 
services, while other payers have shorter decision timeframes for the 
prior authorization of drugs than for non-drug items and services.
    We are proposing to establish a requirement that state CHIP FFS 
programs must provide notice to providers and beneficiaries of prior 
authorization decisions for prescription drugs for which FFP is 
available in accordance with the beneficiary's medical needs but no 
later than 24 hours after receiving the prior authorization request. 
This proposal would align with the existing state Medicaid FFS program 
requirements for covered outpatient drugs in section 1927(d)(5)(A) of 
the Act.
    This proposed alignment for timeframe requirements should ensure 
that providers and patients have similarly efficient processes across 
all impacted payers and within CMS programs, regardless of how drugs 
are categorized under the Act. We are proposing an October 1, 2027 
compliance date.
    In summary, we request comment on our proposals in the CFR 
citations listed in Table 6, and specifically on the following:
     The proposal to require state CHIP FFS programs to provide 
notice to providers and patients of prior authorization decisions in 
accordance with the beneficiary's medical needs, but no later than 24 
hours after receiving a prior authorization request for prescription 
drugs for which FFP is available.
     The proposed October 1, 2027 compliance date.
4. Update to State Medicaid and CHIP Fee-for-Service Programs' Decision 
Timeframe Terminology
    After finalizing the 2024 CMS Interoperability and Prior 
Authorization final rule, we determined that the regulations in 42 CFR 
440.230(e) and 42 CFR 457.495(d) needed to be written more clearly to 
align with the finalized policy as explained in that rule (89 FR 8897). 
In 42 CFR 440.230(e), we established that state Medicaid FFS programs 
must make prior authorization decisions on requests for non-drug items 
and services no later than 7 calendar days for standard requests and 72 
hours for expedited requests. We also provided that states could 
establish shorter timeframes, with which the state

[[Page 19939]]

Medicaid agency would have to comply. The regulation refers to this as 
a ``shorter minimum timeframe,'' but the intent of this requirement is 
to establish a maximum period of time for a state to make a decision on 
a prior authorization request. We are therefore proposing to remove the 
word ``minimum'' to explain that states may establish timeframes that 
are shorter, but not longer, than those we finalized.
    Similarly, 42 CFR 457.495(d) accounts for state laws that may 
establish different timeframes but does not limit those requirements to 
being shorter than the 14 days for standard requests and 72 hours for 
expedited requests. Therefore, we are proposing to align the language 
for state CHIP FFS program timeframes with that for state Medicaid FFS 
program timeframes by specifying that state CHIP FFS programs must make 
prior authorization decisions for non-drug items and services no later 
than 7 calendar days for standard requests and 72 hours for expedited 
requests unless a shorter timeframe is established by the state. Both 
these proposals are consistent with the explanation of our finalized 
policies in the 2024 CMS Interoperability and Prior Authorization final 
rule (89 FR 8879). We propose that this change would be effective on 
the effective date of the final rule, as it does not change the 
existing regulatory requirement.
    In summary, we request comment on our proposals in the CFR 
citations listed in Table 6, and specifically on the following:
     The proposal to revise regulatory language for state 
Medicaid FFS programs and add regulatory language for state CHIP FFS 
programs to explain that state Medicaid and CHIP FFS programs must make 
prior authorization decisions available for non-drug items and services 
no later than 7 calendar days for standard requests and 72 hours for 
expedited requests unless a shorter timeframe is established by the 
state.
     The proposal to become effective beginning on the 
effective date of the final rule.
5. Proposed Changes to Reporting Deadlines and Reporting Levels for 
Publicly Reported Prior Authorization Metrics for Non-Drug Items and 
Services for Medicaid Managed Care Plans and CHIP Managed Care Entities
    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we finalized requirements for impacted payers to publicly report 
certain prior authorizations metrics about non-drug items and services 
annually beginning in 2026.\142\ By sharing these data, payers can 
build trust with their patients and providers and showcase their 
commitment to improving services. We recognize the need for greater 
transparency in the prior authorization process and for information to 
be available to the public. Beyond information about which services 
require prior authorization and the requirements for approval, greater 
transparency about payer performance on denials, timeframes, and 
volumes could help the public and identify opportunities for 
improvement.
---------------------------------------------------------------------------

    \142\ See 42 CFR 422.122(c) for MA organizations and applicable 
integrated plans, 42 CFR 440.230(e)(3) for state Medicaid FFS 
programs, 42 CFR 457.732(c) for state CHIP FFS programs, 42 CFR 
438.210(f) for Medicaid managed care plans, through existing cross 
reference to 42 CFR 438.210 in 42 CFR 457.1230(d) for CHIP managed 
care entities, and 45 CFR 156.223(c) for individual market QHP 
issuers on the FFEs.
---------------------------------------------------------------------------

    We finalized an annual March 31 deadline for all impacted payers to 
publicly post prior authorization metrics for the previous year.\31\ 
However, we have determined that such a deadline may not align with 
Medicaid managed care plans' and CHIP managed care entities' contract 
rating periods. For example, Medicaid managed care plan contract rating 
periods, as defined in 42 CFR 438.2, do not all use the same time 
period and each state may choose different contract rating periods for 
each managed care program. Similarly (though rate certifications are 
not required for CHIP managed care entities), the rating periods for 
CHIP managed care entities vary across states. Because rating periods 
do not necessarily align with calendar years, we now believe that the 
March 31 reporting deadline finalized in the 2024 CMS Interoperability 
and Prior Authorization final rule is not appropriate for all Medicaid 
managed care plans and CHIP managed care entities.\143\ Therefore, to 
align the reporting deadlines with the contract rating period for each 
program, we are now proposing to require Medicaid managed care plans 
and CHIP managed care entities to publicly post the required prior 
authorization metrics no later than 90 days after the end of their 
rating period.
---------------------------------------------------------------------------

    \143\ See 42 CFR 422.122(c) for MA organizations and applicable 
integrated plans, 42 CFR 440.230(e)(3) for state Medicaid FFS 
programs, 42 CFR 457.732(c) for state CHIP FFS programs, 42 CFR 
438.210(f) for Medicaid managed care plans, through cross reference 
to 42 CFR 438.210 in 42 CFR 457.1230(d) for CHIP managed care 
entities, and 45 CFR 1562.223(c) for individual market QHP issuers 
on the FFEs.
---------------------------------------------------------------------------

    We also propose to amend the existing requirements for Medicaid 
managed care plans and CHIP managed care entities to require that they 
report the prior authorization metrics finalized in the 2024 CMS 
Interoperability and Prior Authorization final rule by program, as well 
as by plan. For consistency with the other Medicaid and CHIP managed 
care reporting requirements, we believe that it is appropriate to also 
collect these metrics at the program level. Specifically, if a managed 
care plan contracts with the state for multiple programs (for example, 
an adult and child acute care program and a long-term services and 
supports [LTSS] program), each program's prior authorization metrics 
would be reported separately. This is also consistent with how states 
must report all data in the Managed Care Program Annual Report (MCPAR), 
as described in 42 CFR 438.66(e). Integrated plans would continue to 
report non-drug items and services covered by MA organizations at the 
MA contract level, as the separate requirements for MA organizations 
and Medicaid managed care plans apply under their respective contracts. 
However, integrated plans would be required to report non-drug items 
and services covered by Medicaid managed care plans at both the plan 
and program level. That approach is consistent with the reporting 
requirements finalized in the 2024 CMS Interoperability and Prior 
Authorization final rule for non-drug items and services (89 FR 8897). 
We propose that this change would be effective on the effective date of 
the final rule to align the reporting requirements as soon as 
practicable.
    In summary, we request comment on our proposals in the CFR sections 
listed in Table 6, and specifically on the following:
     The proposal to modify the deadlines for Medicaid managed 
care plans and CHIP managed care entities to report certain metrics 
about prior authorizations for non-drug items and services to be no 
later than 90 days after the end of their contract rating period.
     The proposal to require Medicaid managed care plans and 
CHIP managed care entities to report certain metrics about prior 
authorizations for non-drug items and services, finalized in the 2024 
Interoperability and Prior Authorization final rule, by program, as 
well as by plan.
     The proposals to become effective beginning on the 
effective date of the final rule.

6. Proposed Changes to Publicly Reported Prior Authorization Metrics 
for Non-Drug Items and Services for Impacted Payers
    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we finalized a requirement that impacted payers report certain 
prior authorization metrics aggregated for all non-drug items and 
services on their public websites (89 FR 8897). After further 
consideration, we are proposing to amend those metrics to provide more 
useful and complete information. Currently, impacted payers must report 
the percentage of prior authorizations that were approved, denied, 
approved after appeal, and approved after the timeframe for review was 
extended (89 FR 8889-8890). We are proposing to also require impacted 
payers to report a numeric count of prior authorization requests, as 
well as percentages, for certain existing metrics.
    In addition, we are proposing to add four metrics that are 
complementary to existing metrics. For simplicity, we use the term 
``reporting period'' to describe the period from which data must be 
reported. Specifically, the reporting period for MA organizations, 
state Medicaid and CHIP FFS programs, and QHP issuers on the FFEs would 
be the calendar year and the reporting period for Medicaid managed care 
plans and CHIP managed care entities would be the rating period. We 
propose to require impacted payers to report the following:
     The total number and percentage of standard prior 
authorization requests for non-drug items and services that remain 
denied after appeal during the reporting period.\144\
---------------------------------------------------------------------------

    \144\ Appeals for MA organizations are described in 42 CFR 422 
Subpart M. Appeals for state Medicaid FFS programs (known as fair 
hearings) are described in 42 CFR 431 Subpart E and for Medicaid 
managed care plans in 42 CFR 438 Subpart F. Appeals for state CHIP 
FFS programs are described in 42 CFR 457 Subpart K and for CHIP 
managed care entities in 42 CFR 457.1260. Appeals for QHP issuers on 
the FFEs are described in 45 CFR 147.136.
---------------------------------------------------------------------------

    ++ Numerator: The total number of standard prior authorization 
requests for non-drug items and services that were appealed and the 
denial was upheld.
    ++ Denominator: The total number of adjudicated appeals for 
standard prior authorization requests for non-drug items and services.
     The total number and percentage of expedited prior 
authorization requests for non-drug items and services that remain 
denied after appeal during the reporting period.
    ++ Numerator: The total number of expedited prior authorization 
requests for non-drug items and services that were appealed and the 
denial was upheld.
    ++ Denominator: The total number of adjudicated appeals for 
expedited prior authorization requests for non-drug items and services.
     The total number and percentage of standard prior 
authorization requests for non-drug items and services for which the 
timeframe for review was extended, and the request was denied during 
the reporting period.
    ++ Numerator: The total number of standard prior authorization 
requests for non-drug items and services for which the timeframe for 
review was extended and the request was denied.
    ++ Denominator: The total number of standard prior authorization 
requests for non-drug items and services.
     The total number and percentage of expedited prior 
authorization requests for non-drug items and services for which the 
timeframe for review was extended, and the request was denied during 
the reporting period.
    ++ Numerator: The total number of expedited prior authorization 
requests for non-drug items and services for which the timeframe for 
review was extended and the request was denied.
    ++ Denominator: The total number of expedited prior authorization 
requests for non-drug items and services.
    The proposed metrics for standard prior authorization requests that 
are ``denied after appeal'' and ``for which the timeframe for review 
was extended and the request was denied'' are complementary to the 
existing metrics for the percentage of standard prior authorization 
requests that are ``approved after appeal'' or ``for which the 
timeframe for review was extended and the request was approved.'' The 
two sets of metrics should generally sum to the total number of 
standard prior authorization requests for non-drug items and services 
that were appealed and the total number of standard prior authorization 
requests for non-drug items and services for which the timeframe for 
review was extended. For all metrics we are proposing that are related 
to appeals, appeals include both appeals reviewed internally by the 
impacted payer as well as by external organizations an impacted payer 
may contract with to review and process appeals. Appeals include all 
levels of appeal; internal and external appeals should not be 
differentiated between and should be aggregated as one metric. Appeals 
that have not been fully adjudicated within the reporting period may be 
excluded from the metrics. In addition, we propose that impacted payers 
report on the following:
     The total number and percentage of expedited prior 
authorization requests for non-drug items and services for which the 
timeframe for review was extended, and the request was approved during 
the reporting period.
    ++ Numerator: The total number of expedited prior authorization 
requests for non-drug items and services for which the timeframe for 
review was extended and the request was approved.
    ++ Denominator: The total number of expedited prior authorization 
requests for non-drug items and services.
     The total number and percentage of expedited prior 
authorization requests for non-drug items and services that were 
approved after appeal during the reporting period.
    ++ Numerator: The total number of expedited prior authorization 
requests for non-drug items and services that were appealed, and the 
denial was overturned.
    ++ Denominator: The total number of adjudicated appeals for 
expedited prior authorization requests for non-drug items and services.
    These two metrics would align the metrics for expedited prior 
authorizations with those for standard prior authorizations. For MA 
organizations, extensions are described in 42 CFR 422.568(b)(2). For 
state Medicaid FFS programs, extensions are described in 42 CFR 
440.230(e)(1)(i). For state CHIP FFS programs, extensions are described 
in 42 CFR 457.495(d). For Medicaid managed care plans, extensions are 
described in 42 CFR 438.210(d), and by cross-reference in 42 CFR 
457.1230(d) for CHIP managed care entities. For QHP issuers on the 
FFEs, extensions would be described by the proposal, discussed earlier, 
in 45 CFR 156.223(h)(3). Notably, 42 CFR 440.230 does not provide for 
expedited prior authorization requests to be extended by state Medicaid 
FFS programs. Therefore, we are not proposing those metrics for state 
Medicaid FFS programs. The existing and proposed metrics for non-drug 
items and services are listed in Table 5.
    We are proposing to require impacted payers to publicly report 
these additional data to ensure these reports are useful and robust, as 
well as to align with other CMS reporting requirements. We believe that 
to make these metrics truly useful, CMS and the public must understand 
the scope of the prior authorization requests, both as an absolute 
number and as a percentage, because these numbers are complementary. 
The absolute number provides a scale and reveals the number of prior 
authorization requests submitted to the payer over the previous

[[Page 19941]]

reporting period. A percentage, on the other hand, provides an easy-to-
understand metric to compare payers. Both of those numbers are 
important to provide context to individuals reviewing the reported 
data. Percentages and absolute numbers also allow for comparison across 
impacted payers and could highlight differences between payers, both in 
the number of prior authorization requests that they receive, as well 
as the approval rates at each stage of the process. Furthermore, using 
both the absolute number and percentage of prior authorizations in 
these metrics may avoid misinterpretation of the data. For instance, a 
small percentage of denied prior authorizations may seem insignificant 
until one understands that it represents thousands of prior 
authorizations. Conversely, for a payer that requires few prior 
authorizations, a large percentage of denials may be misinterpreted. 
Therefore, reporting both the number and percentage of prior 
authorization decisions by payers over the previous reporting period 
provides more comprehensive and useful information of these data while 
ensuring that the interpretation of these data is accurate and properly 
contextualized.
    We also propose minor wording changes to simplify the existing 
metrics and specify that the proposal include the ``total number'' of 
prior authorizations for each metric rather than ``aggregated for all 
items and services.'' We do not intend this proposal to change any 
policy or the definition of the metrics.
[GRAPHIC] [TIFF OMITTED] TP14AP26.283

    We are proposing that, if finalized, these additional metrics be 
effective beginning on the effective date of the final rule to be 
reported in the following year. We believe that producing these metrics 
would be a relatively straightforward task for impacted payers that 
have built their systems to generate the metrics required to be 
reported beginning in 2026. For example, percentages are derived from 
numeric counts of numerators and denominators. The numerator should 
reflect the subset of interest, such as requests approved or denied, 
and the denominator should be the total number of prior authorization 
requests (for all metrics not related to appeals). For metrics related 
to appeals, the denominator should be the total number of decided 
appeals of prior authorization requests during the reporting period. If 
an impacted payer has calculated the percentages for the existing 
metrics, they should already have available the numeric counts without 
additional burden. The proposals would require impacted payers to 
publicly report those numeric counts that they should already have. In 
addition, several of the proposed metrics are complementary to the 
existing metrics. For example, impacted payers must currently report on 
the percentage of standard prior authorization requests that were 
approved after appeal. In order to calculate that percentage, impacted 
payers would also have to know how many requests were denied after 
appeal, as those two percentages should total to 100 percent of the 
adjudicated appeals. Therefore, we believe there should be minimal 
additional burden to report the proposed new metrics and impacted 
payers should be able to report the additional metrics by the effective 
date of the final rule. We believe that the immediate transparency 
benefits to the public weigh in favor of an effective date as soon as 
possible. Finally, these additional metrics should provide much-needed 
context to the payer's prior authorization program; therefore, we are 
proposing that the additional metrics be required for the first 
reporting deadline after the effective date of the final rule.
    In summary, we request comment on our proposals in the CFR 
citations listed in Table 6, and specifically on the following:
     The proposal to require impacted payers to report the 
prior authorization metrics regarding non-drug items and services 
listed as ``new'' metrics in Table 5 on their public websites.
     The proposal to become effective beginning on the 
effective date of the final rule.
7. Proposed Requirement To Publicly Report Prior Authorization Metrics 
for Drugs for Impacted Payers
    To incorporate drugs into the existing prior authorization metrics, 
we are now proposing to require impacted payers to annually report 
certain metrics about prior authorizations for all drugs (excluding 
covered Part D drugs for MA-PDs) by posting this information on their 
public website. Covered Part D drugs and PDPs are not included in this 
proposal because they are covered in other reporting regulations, and 
it would be burdensome to add new, duplicative reporting requirements 
on these plans. The Part D program already has reporting requirements 
for aggregated coverage determinations,

[[Page 19942]]

redeterminations, and reopenings for covered Part D drugs.\145\
---------------------------------------------------------------------------

    \145\ Existing reporting requirements for PDPs may be found at: 
Centers for Medicare & Medicaid Services. (2024). Part D Reporting 
Requirements. Retrieved from https://www.cms.gov/medicare/coverage/prescription-drug-coverage-contracting/part-d-reporting-requirements.
---------------------------------------------------------------------------

    We propose that impacted payers, other than Medicaid managed care 
plans and CHIP managed care entities, be required to annually report 
the previous calendar year's metrics regarding all drugs, excluding 
covered Part D drugs for MA-PDs, on their public websites beginning in 
2028 (with data from 2027) following any calendar year that any of 
these impacted payers offered that type of plan. We propose to require 
that these metrics be made publicly available on those impacted payers' 
websites no later than March 31 to be consistent with the reporting 
requirements finalized in the 2024 CMS Interoperability and Prior 
Authorization final rule for non-drug items and services.\146\ To align 
with our proposal to amend the reporting deadline for Medicaid managed 
care plans and CHIP managed care entities, discussed previously in 
section II.C.5. of this proposed rule, we are proposing to require 
Medicaid managed care plans and CHIP managed care entities to publicly 
post the required prior authorization metrics no later than 90 days 
after the end of their rating period.
---------------------------------------------------------------------------

    \146\ See 42 CFR 422.122(c) for MA organizations and applicable 
integrated plans, 42 CFR 440.230(e)(3) for state Medicaid FFS 
programs, 42 CFR 457.732(c) for state CHIP FFS programs, 42 CFR 
438.210(f) for Medicaid managed care plans, through existing cross 
reference to 42 CFR 438.210 in 42 CFR 457.1230(d) for CHIP managed 
care entities, and 45 CFR 156.223(c) for individual market QHP 
issuers on the FFEs.
---------------------------------------------------------------------------

    To tie the metrics to the appropriate terminology for covered 
drugs, we propose that for these metrics, MA organizations would 
include any drugs payable under Part B that require prior 
authorization. Our understanding is that MA organizations do not 
require separate prior authorization requests for drugs payable under 
Part A. Rather, when prior authorization is required, it is requested 
and approved as part of a bundled payment for inpatient services. 
Therefore, because they are aggregated into requests for other items 
and services, we are not including drugs payable under Part A in the 
scope of the metrics we are proposing to require MA organizations to 
report. However, we request comment on whether there are drugs payable 
under Part A that require prior authorization separate from other items 
and services. If that is the case, we believe that metrics about drugs 
payable under Part A would be as important as those we are proposing 
for drugs payable under Part B. Therefore, we would consider finalizing 
that MA organizations report the proposed metrics by aggregating data 
from drugs payable under Part A and Part B.
    State Medicaid and Medicaid managed care plans would report on all 
prescribed drugs described in section 1905(a)(12) of the Act that 
require prior authorization. State CHIP FFS programs and CHIP managed 
care entities would report on all prescription drugs described in 
section 2110(a)(6) of the Act that require prior authorization. 
Finally, QHP issuers on the FFEs would include all drugs covered by the 
issuer that require prior authorization.
    Excluding any category of drug would provide an incomplete picture 
of the burden and impact of a payer's prior authorization practices. 
Some specialty and high-cost drugs may be subject to different 
utilization management requirements or denial rates. By being 
inclusive, we promote transparency and accountability for the prior 
authorization process across all types of drugs. For all of the reports 
for which we are proposing a percentage, we are also proposing that 
each impacted payer provide, as part of its report, the metrics' 
calculated numerators and denominators to provide a greater level of 
detail. Appeals that have not been fully adjudicated within the 
reporting period may be excluded. Furthermore, we recommend that 
impacted payers consider the format of their reports so that the data 
can be easily understood both in writing and graphically. An example of 
this type of report is available on the Medicare website for the FFS 
program.\147\

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

    We propose to require MA organizations to post the following 
metrics from the previous calendar year on their public websites:
     A list of all drugs payable under Part B that require 
prior authorization.
     The total number and percentage of approved standard prior 
authorization requests for Part B drugs during the calendar year.
    ++ Numerator: The total number of approved standard prior 
authorization requests for Part B drugs.

requests for Part B drugs.
     The total number and percentage of denied standard prior 
authorization requests for Part B drugs during the calendar year.
    ++ Numerator: The total number of denied standard prior 
authorization requests for Part B drugs.
    ++ Denominator: The total number of standard prior authorization 
requests for Part B drugs.

    We propose to align impacted payers' reporting levels with those we 
finalized in the 2024 CMS Interoperability and Prior Authorization 
final rule.\151\ Specifically, we propose that MA organizations would 
report at the contract level (applicable integrated plans would report 
drugs covered by MA organizations at the MA contract level), state 
Medicaid and CHIP FFS programs would report at the state level, 
Medicaid managed care plans and CHIP managed care entities would report 
at the plan and program level (if coverage of drugs is included in 
their contract), and QHP issuers on the FFEs would report at the issuer 
level.
---------------------------------------------------------------------------

    \151\ See 42 CFR 422.122(c) for MA organizations and applicable 
integrated plans, 42 CFR 440.230(e)(3) for state Medicaid FFS 
programs, 42 CFR 457.732(c) for state CHIP FFS programs, 42 CFR 
438.210(f) for Medicaid managed care plans, through existing cross 
reference to 42 CFR 438.210 in 42 CFR 457.1230(d) for CHIP managed 
care entities, and 45 CFR 156.223(c) for individual market QHP 
issuers on the FFEs.
---------------------------------------------------------------------------

    We believe that the contract level is appropriate for MA 
organizations because they generally have multiple plans under the same 
contract (89 FR 8890). It is common for MA organizations to offer a 
variety of plans within a service area. The contract-level data are 
aggregated data collected from the plan benefit packages (PBPs) for all 
MA plans provided under an individual contract. Data are specific to 
the contract to which they correspond. CMS already requires MA 
organizations to report some contract-level data about their 
organization determinations on an annual basis and assigns Star Ratings 
at the contract level.
    We are proposing to align the reporting levels for state Medicaid 
and CHIP FFS programs in this proposed rule with those finalized in the 
2024 CMS Interoperability and Prior Authorization final rule (89 FR 
8897) and the proposed amendment for Medicaid managed care plans and 
CHIP managed care entities described in section II.C.5. of this 
proposed rule--that is, at the state level for state Medicaid and CHIP 
FFS programs and at the plan and program level for Medicaid managed 
care plans and CHIP managed care entities--to create a cohesive and 
standardized approach to reporting for the long-term for comparability 
and analysis for both medical services and drugs.
    Similarly, requiring individual market QHP issuers on the FFEs to 
report at the issuer level is consistent with their reporting on 
quality improvement strategies as described in section 1311(g) of the 
Affordable Care Act and 45 CFR 156.1130, which also provides 
consistency with other reporting requirements for QHP issuers on the 
FFEs' (89 FR 8890). Our proposals for consistency across reporting 
requirements aim to reduce the reporting burden on issuers and ensure 
the publication of metrics in a method that issuers are familiar with. 
We note that it is also consistent with the Transparency in Coverage 
(TiC) reporting requirements in 45 CFR 156.220 and the level at which a 
QHP issuer on the FFEs must submit its certification application to 
participate in an FFE or an SBE-FP. This level is represented by the 
six-digit ``Issuer ID'' assigned to each QHP issuer on the FFEs as part 
of the QHP Certification application process, as explained in CMS's 
Application Instructions.\152\ While a parent organization may perform 
some of the work associated with reporting this information and may opt 
to publish the information on its website, the information must be 
available based on an issuer level as is required by regulation in 45 
CFR 156.220 and as specified in the QHP Certification Application 
Instructions.

    In summary, we request comment on our proposals in the CFR sections 
listed in Table 6, and specifically on the following:
     The proposal to require MA organizations to report metrics 
about prior authorization for drugs payable under Part B, and to 
require state Medicaid and CHIP FFS programs, Medicaid managed care 
plans, CHIP managed care entities, and QHP issuers on the FFEs to 
report metrics about prior authorization metrics for drugs on their 
public websites.
     The proposal to require MA organizations, state Medicaid 
and CHIP FFS programs, and QHP issuers on the FFEs to annually report 
the previous calendar year's metrics on their public websites no later 
than March 31 following any calendar year that the impacted payer 
offered that type of plan.

[[Page 19945]]

     The proposal to require Medicaid managed care plans and 
CHIP managed care entities to annually report the previous rating 
period's metrics on their public websites no later than 90 days after 
the end of their rating period.
     The proposal to require MA organizations to report at the 
contract level (applicable integrated plans would report drugs covered 
by MA organizations at the MA contract level), state Medicaid and CHIP 
FFS programs to report at the state level, Medicaid managed care plans 
and CHIP managed care entities to report at the plan and program level 
(if coverage of drugs is included in their contract), and QHP issuers 
on the FFEs to report at the issuer level.
     The proposed 2028 compliance dates to report metrics from 
the 2027 reporting period.
    In addition, we request comments on the following:
     Whether there are drugs payable under Part A that require 
prior authorization separate from other non-drug items and services 
that should be included in the scope of the proposed metrics for MA 
organizations.

8. Statutory Authorities
a. Medicare Advantage
    Section 1856(b) of the Act directs the Secretary to establish 
regulatory standards for MA organizations that are consistent with and 
carry out Part C of Title XVIII of the Act. In addition, section 
1857(e)(1) of the Act explicitly authorizes the addition of reporting 
requirements by MA organizations as a contract term between the 
Secretary and a MA organization where not inconsistent with Part C of 
Title XVIII of the Act and as the Secretary may find necessary and 
appropriate. The proposal for MA plans to publicly report additional 
prior authorization metrics for drugs payable under Part B reflects a 
necessary and appropriate requirement that is consistent with and 
carries out Part C, as it should enable patients to assess the 
implementation of the proposals in this rule. A review of these metrics 
on individual websites may help CMS understand the impact of the 
proposed requirements, including the effects of using the Prior 
Authorization API for drugs payable under Part B. These data may also 
help plans evaluate and modify their operational policies, improve 
their use of the Prior Authorization API, and determine if any policy 
updates would be appropriate.
b. State Medicaid and CHIP
    Section 1902(a)(3) of the Act addresses the requirements for the 
states to provide policies to protect beneficiaries through 
opportunities for fair hearings when their services are denied or not 
acted upon with reasonable promptness. Section 1902(a)(19) of the Act 
underpins timeliness standards and requires Medicaid state plans to 
provide safeguards necessary to assure that eligibility for Medicaid-
covered services will be determined and such services will be provided 
consistently with simplicity of administration and in the best 
interests of recipients. We have proposed that state Medicaid FFS 
programs and Medicaid managed care plans publish additional data about 
their prior authorization performance specific to drugs, and we rely on 
the authorities for Medicaid managed care plans under section 
1932(c)(2)(A)(i) of the Act, which supports managed care access 
standards and requires that states that contract with Medicaid MCOs 
develop and implement a quality assessment and improvement strategy 
that includes standards for access to care so that covered services are 
available within reasonable timeframes. For this proposal, CMS would 
rely on our authority in section 1902(a)(4) of the Act to adopt these 
standards for PIHPs and PAHPs. This would ensure that the same 
requirements apply to MCOs, PIHPs, and PAHPs.
    For CHIP, we propose these requirements under the authority of 
section 2101(a) of the Act, which sets forth that the purpose of Title 
XXI is to provide funds to states to provide child health assistance to 
uninsured, low-income children effectively and efficiently that is 
coordinated with other sources of health benefits coverage. This 
provision authorizes us to propose these requirements for CHIP to 
obtain access to program data for analysis. Such analysis supports 
improvements in the efficacy of CHIP programs and more efficient 
administration of services.
    We expect that the proposal for state CHIP FFS programs to make 
prior authorization decisions on all drugs no later than 24 hours 
should improve timeliness and support process improvements for the 
state, which is consistent with our authorities under section 2101(a) 
of the Act in that it enhances the efficiency of the CHIP program.
    Further, as authorized under section 2107(b)(1) of the Act, the 
proposal to require state CHIP FFS programs and CHIP managed care 
entities to report prior authorization metrics publicly should also 
support the states' oversight, evaluation, and administration 
responsibilities.
c. Qualified Health Plan Issuers on the Federally-facilitated Exchanges
    The proposals to require QHP issuers on the FFEs to provide the 
specific reason for denial of prior authorizations of drugs when 
notifying the provider; notify providers of prior authorization 
decisions for non-drug items and services and drugs, and to do so 
within specified timeframes; and publish certain metrics on their 
websites, are authorized by section 1311(e)(1) of the Affordable Care 
Act. Section 1311(e)(1)(A) of the Affordable Care Act requires that 
Exchanges only certify plans as QHPs if they meet the requirements for 
certification promulgated by the Secretary under section 1311(c)(1) of 
the Affordable Care Act, and section 1311(e)(1)(B) of the Affordable 
Care Act provides discretion to certify QHPs if the Exchange determines 
that making available such plans available is in the interests of 
qualified individuals and qualified employers in the state or states in 
which such Exchange operates. We are of the view that these proposals 
are appropriate QHP certification requirements because they strive to 
expand several key regulatory and patient-protection obligations 
established under the Affordable Care Act.
    We are proposing to require QHP issuers on the FFEs to notify 
providers of prior authorization decisions for non-drug items and 
services within the same timeframes applicable to other impacted 
payers, as established in the 2024 CMS Interoperability and Prior 
Authorization final rule (89 FR 8878). Specifically, we are proposing 
to require QHP issuers on the FFEs to notify providers of prior 
authorization decisions on non-drug items and services as expeditiously 
as a patient's health condition requires but no later than 7 calendar 
days after receiving a standard request and no later than 72 hours 
after receiving an expedited request. If finalized, this proposal would 
allow enrollees in health plans on the FFEs to receive covered services 
more quickly, which may improve patient care.
    We also propose to require that QHP issuers on the FFEs make prior 
authorization decisions to providers on all drugs as expeditiously as 
the enrollee's health condition requires, but no later than 72 hours 
after receiving a standard request and, as expeditiously as the 
enrollee's health condition requires, but no later than 24 hours after 
receiving an expedited request. This proposal to require QHP issuers on 
the FFEs to provide notice to requesting providers of prior 
authorization decisions in a shorter timeframe than they are currently 
required to provide notice to patients of prior authorization decisions 
should allow providers to more quickly alter treatment plans, including 
to send updated prescriptions to pharmacies if a prior authorization is 
denied. We consider the proposal to require QHP issuers on the FFEs to 
notify the requesting provider of a prior authorization decision within 
a specific timeframe based on the nature of the request necessary 
because delays can directly impact a patient's health. Drugs sometimes 
need to be taken soon after a diagnosis is rendered and often need to 
be taken consistently and on time for optimal effectiveness. Delays in 
obtaining and taking medication could lead to a worsening of a 
patient's condition, create complications, and potentially require more 
intensive or costly interventions at a later time.
    With respect to the proposal to require QHP issuers on the FFEs to 
publish certain metrics on their websites, we believe that, as payers 
create and analyze prior authorization metrics reports, they would use 
the data to learn about and improve their own

[[Page 19949]]

performance in adjudicating prior authorization requests. Additionally, 
we believe that the public availability of prior authorization decision 
data would further transparency in the interests of qualified 
individuals and qualified employers in the state in which the Exchange 
operates by providing clear information to consumers that they could 
use when selecting a new plan. Similarly, some providers may find 
metrics about prior authorization approvals or appeals useful when 
selecting payer networks.
    If finalized, publicly reported prior authorization metrics for 
drugs could enable CMS to assess the implementation of the policies 
proposed in this rule. Reviewing these metrics on individual websites 
may help CMS understand the impact of the proposed requirements, 
including using the Prior Authorization API for drugs. At the same 
time, the reports could help QHP issuers on the FFEs evaluate and 
improve their own operational processes.
    For the reasons stated in the paragraphs in this section above, we 
have determined that the proposed changes described in sections 
II.C.2.c. and II.C.3.b. of this proposed rule are in the interests of 
qualified individuals and qualified employers in the state or states in 
which an QHP issuer on the FFEs operates.

D. Requirements for Issuers That Offer Small Group Market Qualified 
Health Plans on the Federally-Facilitated Small Business Health Options 
Program Exchanges

1. Introduction
    We propose to apply the existing requirements in 45 CFR 156.221, 45 
CFR 156.222, and 45 CFR 156.223, which were finalized in the 2020 CMS 
Interoperability and Patient Access final rule and in the 2024 CMS 
Interoperability and Prior Authorization final rule (85 FR 25510 and 89 
FR 8758), to small group market QHP issuers on the FF-SHOPs. As 
discussed in section I.B. of this proposed rule, we are also proposing 
that small group market QHP issuers on the FF-SHOPs be considered 
impacted payers for purposes of the proposed QHP issuer requirements 
described throughout this proposed rule.\153\ We emphasize that neither 
individual market QHP issuers on the SBEs nor small group market QHP 
issuers on the SBEs are impacted payers and therefore, would not be 
subject to these proposals.
---------------------------------------------------------------------------

    \153\ See the following sections for these proposals: II.A.2.a. 
through II.A.2.c., II.A.3., II.A.4.b.(1). and II.A.4.b.(2)., 
II.A.4.b.(4). and II.A.4.b.(5)., II.B.3. through II.B.7., II.C.2.c., 
II.C.3.b. and II.C.3.d., II.C.6. and II.C.7., II.E.1. through 
II.E.4., II.F.1.b., II.F.2.b., II.F.2.c., II.F.5.a., and II.F.5.b. 
of this proposed rule.
---------------------------------------------------------------------------

    For requirements in 45 CFR 156.221 that have already taken effect 
for issuers offering individual market QHPs on the FFEs, we propose 
compliance dates in the future for small group market QHP issuers on 
the FF-SHOPs. For example, we are proposing a compliance date of plan 
years beginning on or after January 1, 2028 for small group market QHPs 
on the FF-SHOPs to comply with 45 CFR 156.221(a), whereas the 
compliance date for individual market QHPs on the FFEs was for plan 
years beginning on or after January 1, 2021. For requirements in 45 CFR 
156.222 and 45 CFR 156.223 that we expect to take effect before this 
proposed rule can be finalized, we are also proposing separate 
compliance dates for small group market issuers on the FF-SHOPs that we 
believe are reasonable. For example, we are proposing compliance dates 
for plan years beginning on or after January 1, 2028 for the Provider 
Access and Payer-to-Payer API requirements in 45 CFR 156.222(a) and 
(b), and the requirement in 45 CFR 156.221(f) to report Patient Access 
API usage metrics to CMS. We are also proposing compliance dates of 
October 1, 2027 for the Prior Authorization API requirements in 45 CFR 
156.223(b) and the requirement in 45 CFR 156.223(a) to provide a reason 
to providers for denying a prior authorization for non-drug items and 
services. We believe that the proposed compliance dates are the 
earliest dates that are feasible to implement proposals for small group 
market QHP issuers given the rulemaking timeline.
    We are proposing the same compliance dates of October 1, 2027 for 
certain proposals in this rule that would newly apply to both small 
group market QHPs on the FF-SHOPs and individual market QHPs on the 
FFEs. Those proposals include the requirements to implement and 
maintain certain HL7[supreg] FHIR[supreg] and NCPDP standards to 
support electronic prior authorization for drugs in 45 CFR 
156.223(b)(1)(iii) and (e), as well as notice requirements that create 
prior authorization decision timeframes in 45 CFR 156.223(i). We are 
also proposing the same compliance dates, beginning in 2028, for 
proposals in this rule that would newly apply to both small group 
market QHPs on the FF-SHOPs and individual market QHPs on the FFEs 
regarding reporting API usage metrics to CMS in 45 CFR 156.222(a)(6) 
and (b)(8) and 45 CFR 156.223(e) and publicly reporting prior 
authorization metrics for drugs in 45 CFR 156.223(d).
    We did not apply these policies to small group market QHP issuers 
on the FF-SHOPs in previous rulemaking due to concerns about placing 
burden on these issuers (85 FR 25553 and 89 FR 8767). However, based on 
additional research, all issuers that offer small group market QHPs on 
the FF-SHOPs as of the time of this proposal also offer individual 
market QHPs on the FFEs. Therefore, we anticipate that the burden for 
these issuers to implement these policies for their small group market 
QHPs on the FF-SHOPs should be relatively low because these issuers are 
already required to implement the policies for their individual market 
QHPs on the FFEs. Additionally, we believe that enrollees in small 
group market QHPs on the FF-SHOPs should have access to the benefits of 
health data transparency discussed in previous rulemaking such as 
better coordinated care and the ability to make more informed decisions 
about their care (85 FR 25523 and 89 FR 8820). If these policies are 
finalized as proposed, and these considerations change in the future--
for example, if an issuer that does not offer one or more individual 
market QHPs on the FFEs newly enters an FF-SHOP, then under this 
proposal, we could consider whether to provide an exception to one or 
more of these requirements through our established process, as 
described in section II.D.7. of this proposed rule, during the annual 
QHP certification process, if it is appropriate based on the interests 
of qualified individuals and qualified employers in the state or states 
in which such Exchange operates and an exception is warranted to permit 
the issuer to offer QHPs through the FFE.\154\

2. General API Requirements Background
    In the 2020 CMS Interoperability and Patient Access and the 2024 
CMS Interoperability and Prior Authorization final rules, we finalized 
general API requirements that apply across the Patient Access, Provider 
Access, Payer-to-Payer, and Prior Authorization APIs.\155\ We are now 
proposing to

[[Page 19950]]

require small group market QHP issuers on the FF-SHOPs to implement 
these requirements, which already apply to individual market QHP 
issuers on the FFEs.
---------------------------------------------------------------------------

    \155\ We discuss final requirements in the 2020 CMS 
Interoperability and Patient Access final rule and the 2024 CMS 
Interoperability and Prior Authorization final rule for all impacted 
payers, but for ease of reference, we are only providing citations 
to these requirements for individual market QHP issuers on the FFEs. 
See 45 CFR 156.221(a) for the Patient Access API, 45 CFR 156.222(a) 
for the Provider Access API, 45 CFR 156.222(b) for the Payer-to-
Payer API, and 45 CFR 156.223(b) for the Prior Authorization API for 
individual market QHP issuers on the FFEs.
---------------------------------------------------------------------------

    The previously finalized rules required impacted payers, including 
individual market QHP issuers on the FFEs, to implement and maintain 
API technology conformant with certain applicable standards adopted by 
ONC in 45 CFR 170.215.\156\ Table 3 in this proposed rule lists the 
required and recommended standards and IGs to support API 
implementation, including updates proposed in this rulemaking. Impacted 
payers are permitted to use an updated version of a required standard 
for the APIs under certain conditions. Specifically, payers may use 
updated versions of standards in 45 CFR 170.213 and 45 CFR 170.215 if 
the following conditions are met: (1) the National Coordinator has 
approved the updated version for use in the ONC Health IT Certification 
Program; (2) the updated version of the standard does not disrupt an 
end user's ability to access the required data via that API; and (3) 
the updated standard is not prohibited by law. Payers may also use an 
updated version if required by other applicable law.\157\
---------------------------------------------------------------------------

    \156\ See 45 CFR 156.221(c) for the Patient Access API, 45 CFR 
156.222(a)(1)(ii) for the Provider Access API, 45 CFR 
156.222(b)(1)(ii) for the Payer-to-Payer API, and 45 CFR 156.223(b) 
for the Prior Authorization API.
    \157\ See 45 CFR 156.221(c)(4).
---------------------------------------------------------------------------

    To ensure that the APIs function properly, impacted payers must 
conduct routine testing and monitoring and perform updates as 
appropriate. That includes assessments to verify that the API is fully 
and successfully implementing privacy and security features, such as 
those required for compliance with the HIPAA Privacy Rule and 
``Security Standards for the Protection of Electronic Protected Health 
Information'' (68 FR 8334) (hereinafter referred to as the ``HIPAA 
Security Rule'') which appeared in the Federal Register on February 20, 
2003 (45 CFR part 160 and subparts A and C of part 164), 42 CFR part 2, 
and other applicable laws protecting privacy and security of 
individually identifiable health data.\158\
---------------------------------------------------------------------------

    \158\ See 45 CFR 156.221(c)(2).
---------------------------------------------------------------------------

    As established in the 2020 CMS Interoperability and Patient Access 
final rule, to ensure that developers have the information necessary to 
interact with the APIs, impacted payers must make publicly accessible, 
by posting on their website or via publicly accessible hyperlink(s), 
complete accompanying documentation. That documentation must contain: 
(1) API syntax, function names, required and optional parameters 
supported and their data types, return variables and their types/
structures, exceptions and exception handling methods and their 
returns; (2) the software components and configurations an app must use 
in order to successfully interact with the API and process its 
response(s); and (3) all applicable technical requirements and 
attributes necessary for an app to be registered with any authorization 
server(s) deployed in conjunction with the API.\159\
---------------------------------------------------------------------------

    \159\ See 45 CFR 156.221(d).
---------------------------------------------------------------------------

    As established in the 2020 CMS Interoperability and Patient Access 
and the 2024 CMS Interoperability and Prior Authorization final rules, 
the only reason impacted payers may deny an app or developer API access 
is if it would present an unacceptable level of risk to the security of 
PHI on the payer's system.\160\ These risks include, for example, 
insufficient authentication or authorization controls, poor encryption, 
or reverse engineering. The payer must make that determination using 
objective, verifiable criteria that are applied fairly and consistently 
across all apps and developers.\161\
---------------------------------------------------------------------------

    \160\ See 45 CFR 156.221(e)(1).
    \161\ See 45 CFR 156.221(e)(2).
---------------------------------------------------------------------------

3. Patient Access API
a. Background
    As discussed in the 2020 CMS Interoperability and Patient Access 
final rule, one critical issue in the U.S. health care system is that 
people cannot easily access their health information in interoperable 
forms. Patients and the health care providers caring for them are often 
presented with an incomplete picture of their health and care as pieces 
of their information are stored in various, unconnected systems and do 
not accompany them to every care setting (85 FR 25511). There are 
numerous benefits associated with individuals having access to their 
health data through a method that is built upon widely used standards. 
In the 2020 CMS Interoperability and Patient Access final rule, we 
finalized requirements for impacted payers, including individual market 
QHP issuers on the FFEs, to implement and maintain a Patient Access API 
conformant with certain FHIR standards that permit third-party apps to 
retrieve certain health information, with the approval and at the 
direction of a current individual enrollee or the enrollee's personal 
representative (85 FR 25558). The ability to easily obtain, use, and 
share claims, encounter, and other health data enables patients to more 
effectively and easily use the health care system. Providing this 
ability to enrollees in all QHPs on the FFEs, including small group 
market QHPs on the FF-SHOPs, would empower more people to access their 
health information in a manner best suited for them.
b. Proposals
    In the 2020 CMS Interoperability and Patient Access final rule, we 
finalized a requirement that individual market QHP issuers on the FFEs 
must implement and maintain a Patient Access API conformant with 
certain FHIR standards that permit third-party apps to retrieve certain 
health information, with the approval and at the direction of a current 
individual enrollee or the enrollee's personal representative.\162\ 
Starting with plan years beginning on or after January 1, 2021, 
impacted payers, including individual market QHP issuers on the FFEs, 
have been required to make available any claims and encounter data and 
all data classes and data elements included in a content standard in 45 
CFR 170.213 (USCDI)\163\ with a date of service on or after January 1, 
2016.\164\ Those data must be made available no later than 1 business 
day after the claim is processed or the data are received by the 
individual market QHP issuers on the FFEs.\165\
---------------------------------------------------------------------------

    \162\ See 45 CFR 156.221(a).
    \163\ See 45 CFR 156.221(b)(1)(iii).
    \164\ See 45 CFR 156.221(i)(1).
    \165\ See 45 CFR 156.221(b)(1)(iii).
---------------------------------------------------------------------------

    Per the 2024 CMS Interoperability and Prior Authorization final 
rule, impacted payers would be required to make available through the 
Patient Access API certain data about prior authorizations for non-drug 
items and services that they maintain, beginning in 2027.\166\ The 
required prior authorization information includes the prior 
authorization status; the date the prior authorization was approved or 
denied; the date or circumstance under which the prior authorization 
ends; the non-drug items and services approved; if denied, a specific 
reason why the request was denied; and related structured 
administrative and clinical documentation submitted by a provider.\167\ 
That prior authorization information must be accessible no later than 1 
business day after the payer receives a prior authorization request, 
must be updated no later than 1 business day after any status change,

[[Page 19951]]

and must continue to be accessible for the duration that the 
authorization is active and at least 1 year after the prior 
authorization's last status change.\168\
---------------------------------------------------------------------------

    \166\ See 45 CFR 156.221(b)(1)(iv).
    \167\ See 45 CFR 156.221(b)(1)(iv)(A).
    \168\ See 45 CFR 156.221(b)(1)(iv)(B).
---------------------------------------------------------------------------

    To inform and assist patients who want to access their health 
information via the Patient Access API, the 2020 CMS Interoperability 
and Patient Access final rule also requires impacted payers to provide, 
in an easily accessible location on their public websites and through 
other appropriate mechanisms that they ordinarily use to communicate 
with current and former enrollees, educational resources in non-
technical, simple, and easy-to-understand language. These resources 
must explain at a minimum: (1) general information on steps the 
individual may consider taking to help protect the privacy and security 
of their health information, including factors to consider in selecting 
an app including secondary uses of data, and the importance of 
understanding the security and privacy practices of any app to which 
they would entrust their health information; and (2) an overview of 
which types of organizations or individuals are and are not likely to 
be HIPAA covered entities, the oversight responsibilities of the Office 
for Civil Rights (OCR) and the Federal Trade Commission (FTC), and how 
to submit a complaint to those entities.\169\
---------------------------------------------------------------------------

    \169\ See 45 CFR 156.221(g).
---------------------------------------------------------------------------

    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we also finalized a requirement that, beginning in 2026, impacted 
payers, including individual market QHP issuers on the FFEs, must 
annually report Patient Access API metrics to CMS in the form of 
aggregated, de-identified data. Specifically, individual market QHP 
issuers on the FFEs must report at the issuer level the following 
metrics: (1) the total number of unique patients whose data are 
transferred via the Patient Access API to a health app designated by 
the patient; and (2) the total number of unique patients whose data are 
transferred more than once via the Patient Access API to a health app 
designated by the patient. The 2024 CMS Interoperability and Prior 
Authorization final rule requires individual market QHP issuers on the 
FFEs to report the previous calendar year's metrics to CMS by March 31 
following any year that they offer an individual market QHP on the 
FFEs.\170\
---------------------------------------------------------------------------

    \170\ See 45 CFR 156.221(f).
---------------------------------------------------------------------------

    We are now proposing to apply each of these requirements to small 
group market QHP issuers on the FF-SHOPs to report data from plan years 
beginning on or after January 1, 2028, with reporting deadlines 
beginning in 2029.
    For reporting on Patient Access API usage, we are proposing to 
require small group market QHP issuers on the FF-SHOPs to annually 
report the metrics in 45 CFR 156.221(f) at the issuer level in the form 
and manner and within the timeframes specified by the Secretary. That 
would allow flexibility for CMS to include API usage metrics reporting 
within specific deadlines set for the QHP certification process, which 
in practice is generally the final deadline for the QHP certification 
process that takes place the following year.\171\ We are proposing to 
apply this requirement to small group market QHP issuers on the FF-
SHOPs for plan years beginning on or after January 1, 2028, following 
each plan year that the QHP issuer offers a small group market QHP on 
the FF-SHOP. For example, QHP issuers on the FF-SHOPs would be required 
to submit metrics from plan years in 2028 as part of the QHP 
certification process during 2029 for plan years in 2030. This is 
consistent with our proposal to modify the Patient Access API usage 
reporting deadline from an annual March 31 date, as further discussed 
in section II.F.2.b. of this proposed rule. We believe it is also 
appropriate to align the reporting deadline for small group market QHP 
issuers on the FF-SHOPs with the annual QHP certification process for 
the reasons discussed in section II.F.2.b., and so that issuers do not 
have to adhere to different sets of deadlines for small group market 
QHPs on the FF-SHOPs and individual market QHPs on the FFEs, which 
could cause administrative burden.
---------------------------------------------------------------------------

    \171\ Information about QHP certification, including deadlines 
can be found at https://www.qhpcertification.cms.gov/QHP/aboutthemarketplace/Timeline.
---------------------------------------------------------------------------

    In summary, we request comment on our proposal to apply the 
policies and their compliance dates described previously, and in the 
CFR citations listed in Table 7, to small group market QHP issuers on 
the FF-SHOPs.
4. Provider Access API
a. Background
    While the Patient Access API was a significant first step toward 
sharing individual patient health information with providers, in the 
2024 CMS Interoperability and Prior Authorization final rule we 
explained our belief that it would benefit patients if payers were 
required to make patient data directly available to providers via an 
API that is conformant with certain FHIR standards. In the normal 
course of business, many providers already maintain EHRs and share data 
for a variety of purposes authorized by the patient and/or existing 
law. Therefore, in the 2024 CMS Interoperability and Prior 
Authorization final rule, we required impacted payers to implement and 
maintain a FHIR API that makes patient data available to providers who 
have a contractual relationship with the payer and a treatment 
relationship with the patient.\172\ The Provider Access API has the 
potential to allow payers to build upon their existing systems and 
processes to enhance access to patient data, while continuing to 
protect patient privacy and data security (89 FR 8787).
---------------------------------------------------------------------------

    \172\ See 45 CFR 156.222(a)(1).
---------------------------------------------------------------------------

b. Proposals
    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we finalized a policy that, beginning in 2027, impacted payers, 
including individual market QHP issuers on the FFEs, must implement and 
maintain a Provider Access API to make available patient data upon 
request from an in-network provider if all the following conditions are 
met: (1) the payer authenticates the identity of the provider that 
requests access and attributes the patient to the provider under the 
required attribution process; (2) the patient does not opt out of the 
Provider Access API; and (3) disclosure of the data is not prohibited 
by law. Individual market QHP issuers on the FFEs must make those data 
available no later than 1 business day after receiving a request from 
such a provider.\173\
---------------------------------------------------------------------------

    \173\ See 45 CFR 156.222(a)(2).
---------------------------------------------------------------------------

    The data that impacted payers must make available via the Provider 
Access API include claims and encounter data (excluding provider 
remittances and patient cost-sharing information), all data classes and 
data elements included in a content standard in 45 CFR 170.213 (USCDI), 
and certain information about prior authorizations that the payer 
maintains with a date of service after January 1, 2016. The required 
prior authorization information includes the prior authorization 
status; the date the prior authorization was approved or denied; the 
date or circumstance under which the prior authorization ends; the non-
drug items and services approved; if denied, a specific reason why the 
request was denied; and related structured administrative and clinical 
documentation submitted by a provider. That prior authorization 
information must be accessible no later than 1 business day after the 
individual market QHP issuer on the FFE receives a prior authorization 
request, must be updated no later than 1 business day after any

[[Page 19952]]

status change, and must continue to be accessible for the duration that 
the authorization is active and at least 1 year after the prior 
authorization's last status change.\174\
---------------------------------------------------------------------------

    \174\ See 45 CFR 156.222(a)(2).
---------------------------------------------------------------------------

    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we finalized a requirement that impacted payers, including 
individual market QHP issuers on the FFEs, beginning in 2027, must 
establish and maintain an attribution process to associate patients 
with their in-network providers to ensure that the payer only sends a 
patient's data to providers who have a treatment relationship with that 
patient.\175\ We also finalized a requirement for impacted payers, 
including individual market QHP issuers on the FFEs, to provide on 
their website and through other appropriate provider communications, 
information in plain language explaining the process for requesting 
patient data using the Provider Access API. The resources must include 
information about how to use the payer's attribution process to 
associate patients with their providers.\176\
---------------------------------------------------------------------------

    \175\ See 45 CFR 156.222(a)(3).
    \176\ See 45 CFR 156.222(a)(5).
---------------------------------------------------------------------------

    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we finalized a policy that impacted payers, including individual 
market QHP issuers on the FFEs, beginning in plan years that start on 
or after January 1, 2027, must establish and maintain a process for 
patients to opt out of data exchange via the Provider Access API and 
that allows patients to change their permission at any time.\177\ This 
process must be made available to enrollees before the first date on 
which the payer makes their information available via the Provider 
Access API, and at any time during their enrollment with the 
payer.\178\ Impacted payers, including individual market QHP issuers on 
the FFEs, are also required to provide educational resources in plain 
language to their patients about the Provider Access API.\179\ Those 
resources must include information about the benefits of API data 
exchange with providers; patients' opt out rights; and instructions for 
both opting out of data exchange and for subsequently opting in, should 
patients choose to do so.\180\ Impacted payers must make this 
information available to patients before the first date on which the 
payer makes their information available via the Provider Access API, no 
later than 1 week after the start of coverage, and at least 
annually.181 182 These resources must also be available in 
an easily accessible location on payers' public websites (89 FR 8817-
8818).\183\
---------------------------------------------------------------------------

    \177\ See 45 CFR 156.222(a)(4)(i).
    \178\ See 45 CFR 156.222(a)(4)(i).
    \179\ See 45 CFR 156.222(a)(4)(ii).
    \180\ See 45 CFR 156.222(a)(4)(ii).
    \181\ As discussed in the 2024 CMS Interoperability and Prior 
Authorization final rule, where coverage starts prospectively, the 
deadline would be based on the coverage start date (also known as 
the coverage effective date). In the case of retroactive coverage, 
to avoid a deadline in the past, the deadline for the payer to 
provide the required information about the Payer-to-Payer API, 
request identifying information about previous/concurrent payer(s), 
and an opt in would be based on the date that the payer gets patient 
information and makes the patient's coverage effective (89 FR 8833).
    \182\ See 45 CFR 156.222(a)(4)(ii).
    \183\ See 45 CFR 156.222(a)(4)(ii)(D).
---------------------------------------------------------------------------

    We are now proposing to apply each of these requirements to small 
group market QHP issuers on the FF-SHOPs for plan years beginning on or 
after January 1, 2028. We believe that this proposal's compliance date 
provides sufficient time for those issuers to incorporate their small 
group market QHPs on the FF-SHOPs into their previous API 
implementation for individual market QHPs on the FFEs given that small 
group market QHP issuers on the FF-SHOPs also offer individual market 
QHPs on the FFEs. However, we solicit comment on whether this is the 
case.
    In summary, we request comment on our proposal to apply the 
policies and their compliance dates described previously, and in the 
CFR citations listed in Table 7, to small group market QHP issuers on 
the FF-SHOPs.
5. Payer-To-Payer API
a. Background
    In addition to sharing data with their providers, having a 
patient's data follow them when they change payers, or shared when they 
have health insurance coverage through multiple payers, can have a 
multitude of benefits for patient care. For example, a payer receiving 
data when a new patient enrolls can better support the patient through 
care coordination related to a chronic condition or ongoing treatment 
needs. If necessary, patient data can give payers the information they 
need to assign a case manager or help the patient find providers in 
their new network. Data exchange among payers--specifically, sending 
patient data from a patient's previous payer to their new one--is a 
powerful way to ensure that data follows patients through the health 
care system and improves care continuity, and helps patients to 
maintain access to their record over time. In the 2024 CMS 
Interoperability and Prior Authorization final rule, we required 
impacted payers, including individual market QHP issuers on the FFEs, 
to build a Payer-to-Payer API, with certain standards that would 
facilitate patient data exchange at the start of coverage and between 
concurrent payers.\184\
---------------------------------------------------------------------------

    \184\ See 45 CFR 156.222(b).
---------------------------------------------------------------------------

b. Proposals
    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we finalized a policy that, for plan years beginning on or after 
January 1, 2027, individual market QHP issuers on the FFEs must 
implement and maintain a Payer-to-Payer API to exchange patient health 
information when an enrollee changes payers or has concurrent coverage 
with two or more payers if the following conditions are met: (1) the 
payer that requests access has its identity authenticated and includes 
an attestation with the request that the patient is enrolled with the 
payer and has opted into the data exchange; and (2) the exchange is not 
prohibited by law. Impacted payers, including individual market QHP 
issuers on the FFEs, must make those data available no later than 1 
business day after receiving a request from another payer that meets 
those requirements.\185\
---------------------------------------------------------------------------

    \185\ See 45 CFR 156.222(b)(5).
---------------------------------------------------------------------------

    The data that impacted payers must make available via the Payer-to-
Payer API include claims and encounter data (excluding provider 
remittances and patient cost-sharing information), all data classes and 
data elements included in a content standard in 45 CFR 170.213 (USCDI), 
and certain information about prior authorizations that the payer 
maintains with a date of service within 5 years of the request. The 
required prior authorization information does not include denied prior 
authorization requests. It does include the prior authorization status, 
the date the prior authorization was approved, the date or circumstance 
under which the prior authorization ends, the non-drug items and 
services approved, and related structured and unstructured 
administrative and clinical documentation submitted by a provider. This 
prior authorization information must be accessible no later than 1 
business day after the impacted payer receives a prior authorization 
request, must be updated no later than 1 business day after any status 
change, and must continue to be accessible for the duration that the 
authorization is active and at least 1 year after the prior 
authorization's last status change.\186\
---------------------------------------------------------------------------

    \186\ See 45 CFR 156.222(b)(4).
---------------------------------------------------------------------------

    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we also

[[Page 19953]]

finalized requirements that, for plan years beginning on or after 
January 1, 2027, impacted payers, including individual market QHP 
issuers on the FFEs, must establish and maintain processes to request 
that an enrollee opt into the payer to payer data exchange and submit 
information about their previous and concurrent payers.\187\ Those 
processes must be in place for current enrollees by the compliance date 
of plan years beginning on or after January 1, 2027, and then, for new 
enrollees, no later than 1 week after the coverage start date, or, if 
coverage has a retroactive start date, no later than 1 week after the 
coverage is effectuated (89 FR 8855).\188\ In addition, enrollees must 
be permitted to change their preference at any time.\189\ If an 
enrollee does not respond or additional information is necessary, the 
payer must make reasonable efforts to engage with the enrollee to 
collect this information.\190\ By that compliance date, impacted 
payers, including individual market QHP issuers on the FFEs, are also 
required to provide educational resources in plain language to their 
patients about the Payer-to-Payer API.\191\ Those resources must 
include the benefits of Payer-to-Payer API data exchange, their ability 
to opt in or withdraw that permission, and instructions for doing 
so.\192\ Impacted payers must make this information available to 
patients when requesting an enrollee's permission for Payer-to-Payer 
API data exchange and at least annually thereafter.\193\ These 
resources must also be available in an easily accessible location on 
payers' public websites.\194\

    If an enrollee opts in and provides sufficient information about 
their previous or concurrent payers, then impacted payers, including 
individual market QHP issuers on the FFEs, must request the specified 
data from those payers no later than 1 week after they have sufficient 
identifying information about previous or concurrent payers and the 
enrollee has opted in.\195\ In addition, at an enrollee's request, 
payers must make the same request within 1 week.\196\ Any data received 
in response to such a request must be incorporated into the payer's 
records about the enrollee.\197\ In addition, if an enrollee has 
concurrent payers, the payer must request data from all known 
concurrent payers at least quarterly and must respond to such a request 
from other concurrent payers within 1 business day.\198\
---------------------------------------------------------------------------

    \195\ See 45 CFR 156.222(b)(4)(iv)(A). In the 2024 CMS 
Interoperability and Prior Authorization final rule, in which this 
requirement was finalized for impacted payers including individual 
market QHP issuers on the FFEs, CMS noted that ``sufficient 
information'' refers to information about patients' previous/
concurrent payer(s) that would allow them [the payer] to identify 
and request data from those other payers. CMS left the process of 
gathering this information open for payers to implement in the least 
burdensome, most practical way, and noted payers often have 
established points of contact and existing processes that can apply 
here; for example, that they use to identify concurrent payers to 
facilitate coordination of coverage and Medicare Secondary Payer/
Third Party Liability administration (89 FR 8834-8835).
    \196\ See 45 CFR 156.222(b)(4)(iv)(B).
    \197\ See 45 CFR 156.222(b)(4)(v).
    \198\ See 45 CFR 156.222(b)(6).
---------------------------------------------------------------------------

    We are now proposing to apply each of these requirements to small 
group market QHP issuers on the FF-SHOPs for plan years beginning on or 
after January 1, 2028. We believe that this proposal's compliance date 
provides sufficient time for those issuers to incorporate their small 
group market QHPs on the FF-SHOPs into their previous API 
implementation for individual market QHPs on the FFEs given that small 
group market QHP issuers on the FF-SHOPs also offer individual market 
QHPs on the FFEs. However, we solicit comment on whether this is the 
case.
    In summary, we request comment on our proposal to apply the 
policies and their compliance dates described previously, and in the 
CFR citations listed in Table 7, to small group market QHP issuers on 
the FF-SHOPs.
6. Prior Authorization API and Prior Authorization Process
a. Background
    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we finalized a requirement for impacted payers, including 
individual market QHP issuers on the FFEs, to implement and maintain a 
Prior Authorization API to improve the prior authorization process 
between payers and providers for non-drug items and services.\199\ This 
Prior Authorization API would streamline the prior authorization 
process for providers and for office staff who support the prior 
authorization process by automating certain prior authorization tasks, 
thereby mitigating some of the obstacles of the existing prior 
authorization process and expediting approval of needed care or 
explaining why a submitted request is not sufficient. The API would 
also allow a provider to query the payer's system to determine whether 
a prior authorization was required for certain non-drug items and 
services and identify documentation requirements. It would automate the 
compilation of necessary data for populating the electronic prior 
authorization request and enable payers to provide the status of the 
prior authorization decision, including whether the request has been 
approved or denied. The 2024 CMS Interoperability and Prior 
Authorization final rule also included requirements that payers include 
a specific reason for denial of a prior authorization request in their 
responses to providers,\200\ and publicly report certain prior 
authorization metrics.\201\
---------------------------------------------------------------------------

    \199\ See 45 CFR 156.223(b).
    \200\ See 45 CFR 156.223(a).
    \201\ See 45 CFR 156.223(c).
---------------------------------------------------------------------------

    The 2022 CMS Interoperability and Prior Authorization proposed rule 
and the 2024 CMS Interoperability and Prior Authorization final rule 
both discussed the current burden associated with prior authorization 
processes and explained how making the prior authorization process 
electronic would reduce the time and burden, expediting patients' 
access to care and allowing providers to put time back into direct 
patient care (87 FR 76286 and 89 FR 8862). Requiring all QHP issuers on 
the FFEs, including small group market QHP issuers on the FF-SHOPs, to 
adopt electronic prior authorization processes for non-drug items and 
services would provide these benefits to more patients, and potentially 
help more providers and administrative staff to mitigate burnout. 
Including small group market QHP issuers on the FF-SHOPs in 
requirements to publicly report certain prior authorization metrics and 
to provide a reason for denial of prior authorization in responses to 
providers would improve understanding of prior authorization processes' 
impact on more enrollees and help ensure transparency for more prior 
authorization requests.
    The 2024 CMS Interoperability and Prior Authorization final rule 
also required impacted payers other than individual market QHP issuers 
on the FFEs (MA organizations, state Medicaid and CHIP FFS programs, 
Medicaid managed care plans, and CHIP managed care entities), to 
respond to prior authorization requests within shorter timeframes than 
they were previously subject to (89 FR 8897). We are proposing to apply 
these requirements, and additional requirements related to drug prior 
authorization, to all QHP issuers on the FFEs, including individual 
market QHP issuers on the FFEs and small group market QHP

[[Page 19954]]

issuers on the FF-SHOPs, in this rule. For discussion of those 
proposals please see section II.C.3. of this proposed rule.
b. Proposals
    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we finalized a requirement for individual market QHP issuers on 
the FFEs to implement and maintain a Prior Authorization API to improve 
the prior authorization process between payers and providers for non-
drug items and services.\202\ The purpose of the API is to streamline 
the process and ensure that payers use technology to provide more 
useful information about when and how to obtain a prior authorization 
and the status of an approved or denied prior authorization (89 FR 
8897).
---------------------------------------------------------------------------

    \202\ See 45 CFR 156.223(b).
---------------------------------------------------------------------------

    We finalized a policy that, for plan years beginning on or after 
January 1, 2027, individual market QHP issuers on the FFEs must 
implement and maintain a Prior Authorization API that--(1) is populated 
with the payer's list of non-drug items and services that require prior 
authorization; (2) can identify all documentation required for approval 
of any non-drug items or services that require prior authorization; (3) 
supports a HIPAA-compliant prior authorization request and response; 
and (4) communicates whether the payer approves the prior authorization 
request (and the date or circumstance under which the authorization 
ends), denies the prior authorization request (with a specific reason), 
or requests more information.\203\
---------------------------------------------------------------------------

    \203\ See 45 CFR 156.223(b).
---------------------------------------------------------------------------

    In addition, we finalized two process requirements for impacted 
payers, including individual market QHP issuers on the FFEs, to improve 
the prior authorization process generally. We finalized a policy that 
beginning January 1, 2026, if an impacted payer denies a prior 
authorization request (excluding a request for coverage of drugs as 
defined for QHPs on the FFEs in 45 CFR 156.221(b)(1)(v)), the response 
to the provider must include a specific reason for the denial, 
regardless of the method used to communicate that information.\204\
---------------------------------------------------------------------------

    \204\ See 45 CFR 156.223(a).
---------------------------------------------------------------------------

    We also finalized a requirement that beginning in 2026, following 
each year it offers an individual market QHP on the FFEs, an individual 
market QHP issuer on the FFE must report prior authorization data, 
excluding data on drugs as defined in 45 CFR 156.221(b)(1)(v), at the 
issuer level by March 31. The individual market QHP issuer on the FFE 
must make the following data from the previous calendar year publicly 
accessible by posting them on its website:
     A list of all non-drug items and services that require 
prior authorization.
     The percentage of standard prior authorization requests 
that were approved, aggregated for all non-drug items and services.
     The percentage of standard prior authorization requests 
that were denied, aggregated for all non-drug items and services.
     The percentage of standard prior authorization requests 
that were approved after appeal, aggregated for all non-drug items and 
services.
     The percentage of prior authorization requests for which 
the timeframe for review was extended, and the request was approved, 
aggregated for all non-drug items and services.
     The percentage of expedited prior authorization requests 
that were approved, aggregated for all non-drug items and services.
     The percentage of expedited prior authorization requests 
that were denied, aggregated for all non-drug items and services.
     The average and median time that elapsed between the 
submission of a request and a determination by the individual market 
QHP issuer on the FFE, for standard prior authorizations, aggregated 
for all non-drug items and services.
     The average and median time that elapsed between the 
submission of a request and a decision by the individual market QHP 
issuer on the FFE for expedited prior authorizations, aggregated for 
all non-drug items and services.\205\
---------------------------------------------------------------------------

    \205\ See 45 CFR 156.223(c).
---------------------------------------------------------------------------

    We are now proposing to apply each of these requirements to small 
group market QHP issuers on the FF-SHOPs. Specifically, we propose to 
amend the requirements in 45 CFR 156.223(a) to respond to providers 
with a reason for denial and in 45 CFR 156.223(b) to implement and 
maintain a Prior Authorization API to include small group market QHP 
issuers on the FF-SHOPs with a compliance date of October 1, 2027. In 
addition, we propose to amend the requirement in 45 CFR 156.223(c) to 
publicly report prior authorization metrics to apply it to small group 
market QHP issuers on the FF-SHOPs beginning in 2028 for calendar year 
2027 data. Given that those issuers have met or are working on meeting 
these proposed requirements for their individual market QHPs on the 
FFEs, we believe that the proposed compliance dates provide sufficient 
time to extend their technology solutions and business processes to 
their small group market QHPs on the FF-SHOPs. However, we solicit 
comment on whether this is the case.
    In summary, we request comment on our proposal to apply the 
policies and their compliance dates described previously, and in the 
CFR citations listed in Table 7, to small group market QHP issuers on 
the FF-SHOPs.
7. Exceptions
a. Background
    The 2020 CMS Interoperability and Patient Access final rule and the 
2024 CMS Interoperability and Prior Authorization final rule finalized 
an exceptions process for individual market QHP issuers on the FFEs 
that are not able to implement the Patient Access API. An individual 
market QHP issuer on the FFE can apply for an exception for a 
particular plan year by submitting a narrative justification as part of 
its QHP certification application that describes the reasons why it 
cannot reasonably satisfy the requirements for the applicable plan 
year, the effect of non-compliance upon providers and enrollees, the 
current or proposed means of providing the required information to 
providers or other payers, and solutions and a timeline to achieve 
compliance with the requirements.\206\
---------------------------------------------------------------------------

    \206\ See 156.221(h) for the Patient Access API, 45 CFR 
156.222(c) for the Provider Access and Payer-to-Payer APIs, and 45 
CFR 156.223(d) for the Prior Authorization API.
---------------------------------------------------------------------------

    As discussed in the 2024 CMS Interoperability and Prior 
Authorization final rule, we believe that certifying only health plans 
that implement these APIs is generally in the interests of enrollees 
(89 FR 8786 and 8820). However, as also discussed in that final rule, 
while some individual market QHP issuers on the FFEs are in a position 
to implement the updates that the rule requires, a wide range of 
issuers participate in the FFEs and vary in terms of available 
resources to adopt these requirements (89 FR 8906). Plan offerings can 
also vary by region and even by county, with some areas in the FFEs 
having more limited plan offerings than others. Therefore, this 
exceptions process exists as a safeguard to prevent potential enrollees 
from going without access to QHP coverage because an issuer is unable 
to implement these APIs.
b. Proposals
    We propose to apply the same exceptions process to the proposed 
requirements for small group market

[[Page 19955]]

QHP issuers on the FF-SHOPs as currently applies to individual market 
QHP issuers on the FFEs per 45 CFR 156.221(h), including as cross 
referenced in 45 CFR 156.222(c) and 45 CFR 156.223(d). As we discussed 
in the 2024 CMS Interoperability and Prior Authorization final rule, we 
anticipate that the volume of requests for exceptions should be low 
based on our experience with individual market QHP issuers on the FFEs, 
among which exception requests are uncommon, and a number of requests 
have specified that the issuer intends to comply within the upcoming 
plan year even though they may not be able to do so by January 1 of the 
upcoming year (89 FR 8906). As also discussed in the 2020 CMS 
Interoperability and Patient Access final rule, with regard to 
individual market QHPs on the FFEs, we believe that it is important to 
provide the FFEs with the option to waive this requirement on a limited 
basis, for example, if not certifying the issuer's QHP or QHPs would 
result in consumers having few or no plan options in certain areas (85 
FR 25552). We believe that this rationale also applies to small group 
market QHPs on the FF-SHOPs--that is, that the FF-SHOPs should have the 
option to consider coverage availability for qualified employers and 
their employees as a factor when determining whether to certify an FF-
SHOP plan notwithstanding its failure to comply with requirements for 
the Patient Access API in 45 CFR 156.221, the Provider and Payer-to-
Payer APIs in 45 CFR 156.222(a) and (b), or the Prior Authorization API 
in 45 CFR 156.223(b).
    In summary, we request comment on our proposal to apply the 
policies and their compliance dates described previously, and in the 
CFR citations listed in Table 7, to small group market QHP issuers on 
the FF-SHOPs.

BILLING CODE 4150-28-C

E. Reporting Payer API Endpoints and Associated Information for CMS To 
Publish

1. API Endpoints
    In the 2020 CMS Interoperability and Patient Access final rule, we 
finalized a requirement that impacted payers must implement and 
maintain Patient Access and Provider Directory APIs (85 FR 25513). In 
the 2024 CMS Interoperability and Prior Authorization final rule, we 
finalized requirements that impacted payers must also implement and 
maintain Provider Access, Payer-to-Payer, and Prior Authorization APIs 
(89 FR 8759). During those rulemakings, we received numerous public 
comments that emphasized the importance of a centralized location to 
discover payers' API endpoints, which would realize the full potential 
of these interoperability APIs (85 FR 25562 and 89 FR 8767).
    An API's endpoint is the digital location, often a URL or IP 
address, that is set up to accept secure queries to the API. Developers 
need to know an API's endpoint to configure their apps to interact with 
the API. Without properly structured and functioning endpoints, an API 
will not work as intended. APIs can be set up with multiple endpoints, 
each used for specific data or purposes, or a single endpoint that 
offers different data depending on how it is queried.
    We have received public feedback that a centralized listing of 
impacted payers' API endpoints would significantly improve the ability 
of payers, providers, patients, and developers to use the 
interoperability APIs (89 FR 8767). Various entities within the health 
care system need to have information about payers' API endpoints to 
achieve the envisioned ecosystem of data exchange via the 
interoperability APIs. For the Patient Access API, app developers must 
connect to payers' API endpoints for patients to access their data 
maintained by that payer. For the Provider Access API, EHR developers 
must configure providers' EHRs or other health IT to query payers' API 
endpoints to retrieve patient information maintained by that payer. To 
use the Payer-to-Payer API, payers must locate patients' previous or 
concurrent payers' API endpoints in order to send a request for patient 
data, as required in the 2024 CMS Interoperability and Prior 
Authorization final rule. For the Prior Authorization API, providers 
must be able to find the correct payer API endpoint to submit 
electronic prior authorization requests. Similarly, for the Provider 
Directory API, third-party developers and health care entities need 
discoverable endpoints to create innovative apps that help patients 
find in-network providers and enable care coordination between 
providers, making centralized endpoint reporting essential for 
realizing the full potential of publicly accessible provider directory 
information.
    Stakeholder feedback from our 2019 CMS Interoperability and Patient 
Access proposed rule, 2020 CMS Interoperability and Patient Access 
final rule, 2022 CMS Interoperability and Prior Authorization proposed 
rule, and 2024 CMS Interoperability and Prior Authorization final rule 
demonstrates that endpoint discovery remains a significant 
implementation challenge, with multiple commenters requesting a 
centralized directory and noting that third-party apps currently 
struggle with implementation barriers when working with payers. Finding 
API endpoints individually in myriad locations could be a significant 
task for app developers, EHR developers, providers, and payers, because 
without specific requirements, those endpoints are unlikely to be 
listed or discoverable in a standardized manner. While payers may have 
some incentive to make their endpoints discoverable, market dynamics 
may create barriers to voluntary standardization. For example, 
individual payers may invest resources into comprehensive endpoint 
discovery while competitors benefit without making similar investments 
or competitive considerations, which could lead some payers to maintain 
integration complexity. As part of our oversight and compliance 
process, CMS has engaged in exercises to discover endpoints from a 
sampling of impacted payers. Our own work was heavily manual, and we 
have experienced first-hand that endpoints are listed in a wide variety 
of locations and formats, including PDFs, from which automated data 
retrieval is particularly difficult. Instead, we believe it would help 
everyone in the health care industry for CMS to collect API endpoints 
and make them publicly available in a standardized format that can 
easily be accessed and used by app developers, EHR developers, 
providers, and payers.
    Furthermore, if payers' API endpoints have to be discovered 
individually by developers, or entities that want to use the API, the 
endpoint is more likely to be hard coded into the software systems used 
by those developers or entities. Individual endpoint discovery is 
likely to create a manual, resource-intensive process where developers 
must research each payer's documentation, extract endpoint information, 
and integrate it directly into their code. The alternative--building a 
dynamic endpoint discovery system--requires industry-wide coordination 
and significant development resources that many organizations cannot 
justify, making individual developer hard coding the more practical, 
albeit less flexible, solution. Once endpoints are hard coded, 
maintenance becomes increasingly burdensome, as developers must 
manually monitor hundreds of payers for changes, modify code, test, and 
redeploy systems for each endpoint update. Developers may not realize 
that an endpoint has changed until they receive reports that their 
software is no longer successfully connecting to an API, at which point 
they would have to push software updates. This process could take days 
or weeks, during which API integrations may fail and end users may 
experience service disruptions. This creates operational challenges for 
all entities that depend on API access; entities may need to wait for 
software updates to restore connectivity and access accurate data, 
potentially causing delays in patient care, data exchange, and 
administrative processes. Providers using EHRs, health systems relying 
on integration platforms, and payers using third-party software 
solutions would all experience service interruptions when hard-coded 
endpoints become outdated, regardless of whether they maintain in-house 
development capabilities.
    Instead, a centralized registry could create greater flexibility 
and allow for more timely endpoint data availability. Software could 
make a call to that registry and, with appropriate identifying data, 
find the latest information about a payer's API endpoint. The software 
could then automatically use that information to call the payer's API 
without manual intervention by the developer or entity making the 
request. Such a process could be implemented into health apps (for the 
Patient Access and Provider Directory APIs), EHRs or other provider 
systems (for the Provider Access, Prior Authorization, and Provider 
Directory APIs), and payers' systems (for the Payer-to-Payer API).
    Therefore, we are proposing to require, in the CFR citations listed 
in Table 8, impacted payers to report to CMS their API endpoints for 
each required interoperability API unless the impacted payer is a state 
Medicaid or CHIP FFS program that has been granted an extension or a 
QHP issuer on the FFEs that has been granted an exception from 
implementing any or all of the

[[Page 19958]]

interoperability APIs.\207\ To ensure the standardization of payer 
endpoints, we are proposing to require impacted payers to report their 
API endpoints as an Endpoint Resource, as defined by an unexpired 
version of the Health Level Seven (HL7[supreg]) FHIR[supreg] standard 
adopted in 45 CFR 170.215(a). We are proposing that impacted payers 
would be required to initially report their API endpoints no later than 
60 days after the effective date of a final rule. In future years, we 
are proposing that new impacted payers would be required to report this 
information no later than 60 days before they begin covering patients 
under the applicable CMS program. Thereafter, impacted payers would be 
required to report changes to CMS within 1 week of any changes to their 
API endpoint(s) and verify every 12 months that there have been no 
changes and their data are accurate. API endpoints support time-
sensitive health care operations including prior authorization 
requests, care coordination, and patient data access. Outdated 
endpoints immediately disrupt these critical functions; the underlying 
statutory requirements for timely care, efficient operations, and 
patient access cannot be met with stale endpoint information. 
Verification every 12 months ensures ongoing accuracy of the 
centralized registry, compliance with existing statutory obligations 
for current information, and efficient program administration, through 
reliable endpoint data.
---------------------------------------------------------------------------

    \207\ For the Patient Access API, see 45 CFR 156.221(h) for QHP 
issuers on the FFEs. For the Provider Access and Payer-to-Payer 
APIs, see 42 CFR 431.61(c)(1)-(2) for state Medicaid FFS programs, 
42 CFR 457.731(c)(1) and (2) for state CHIP FFS programs, and 45 CFR 
156.222(c) for QHP issuers on the FFEs. For the Prior Authorization 
API, see 42 CFR 431.80(c)(1) for state Medicaid FFS programs, 42 CFR 
457.732(d)(1) for state CHIP FFS programs, and 45 CFR 156.223(d) for 
QHP issuers on the FFEs.
---------------------------------------------------------------------------

2. API Documentation
    In the 2020 CMS Interoperability and Patient Access final rule, we 
finalized a requirement that impacted payers make the specific business 
and technical documentation necessary to interact with their Patient 
Access and Provider Directory APIs freely and publicly accessible (85 
FR 25542). In the 2024 CMS Interoperability and Prior Authorization 
final rule, we extended that requirement to the Provider Access, Payer-
to-Payer, and Prior Authorization APIs (89 FR 8815). We explained that 
transparency is necessary for developers to easily obtain the 
information needed to develop systems technically compatible with the 
payer's API. Transparency is also needed so that developers can 
understand how to successfully interact with a payer's API. This 
includes how to satisfy any requirements the payer may establish for 
verifying a developer's identity and their apps' authenticity.
    As explained in the preamble to the 2020 CMS Interoperability and 
Patient Access final rule (85 FR 25542), impacted payers must make 
publicly accessible documentation necessary to interact with their 
APIs. The existing regulations in 42 CFR 422.119(d), 42 CFR 431.60(d), 
42 CFR 457.730(d), and 45 CFR 156.221(d) require impacted payers to 
make publicly available documentation that includes API syntax, 
function names, required and optional parameters, software components 
and configurations, and technical requirements for apps to interact 
with their APIs. FHIR capability statements are mandatory resources, as 
defined by an unexpired version of the FHIR standard adopted in 45 CFR 
170.215(a), making them inherently part of this required documentation.
    The required authorization and authentication protocols and 
implementation details build upon the existing requirement for impacted 
payers to use the SMART App Launch IG and OpenID Connect Core--to 
implement certain interoperability APIs.\208\ The SMART App Launch IG 
is a standards-based framework for secure app connections to health IT 
systems, and OpenID Connect Core is an identity verification layer 
built on OAuth 2.0. Those existing requirements necessitate public 
documentation of authentication protocols. API registration 
information, when required by payers, constitutes essential 
documentation that falls within the existing requirement in 42 CFR 
422.119(d)(3), 42 CFR 431.60(d)(3), 42 CFR 457.730(d)(3), and 45 CFR 
156.221(d)(3) to make publicly accessible all applicable technical 
requirements and attributes necessary for an app to be registered with 
any authorization server(s) deployed in conjunction with the API. 
Without registration procedures, developers cannot establish the 
necessary access credentials to use the APIs.
---------------------------------------------------------------------------

    \208\ See, for instance, cross-references to SMART Launch IG in 
45 CFR 170.215(c) and OpenID Connect Core in 45 CFR 170.215(e), for 
the Patient Access API in 42 CFR 422.119(c)(1) for MA organizations, 
42 CFR 431.60(c)(1) for state Medicaid FFS programs, through cross 
reference to 42 CFR 431.60 in 42 CFR 438.242(b)(5) for Medicaid 
managed care plans, 42 CFR 457.730(c)(1) for CHIP FFS programs, 
through cross reference to 42 CFR 438.242 in 42 CFR 457.1233(d) for 
CHIP managed care entities, and 45 CFR 156.221(c)(1) for individual 
market QHP issuers on the FFEs.
---------------------------------------------------------------------------

    To ensure that the business and technical documentation is publicly 
available and easily discoverable, we are proposing to require impacted 
payers to report to CMS the URLs for specific required documentation, 
at the CFR citations listed in Table 8.\209\ CMS would then publish 
these URLs for centralized access. CMS proposes that the required URLs 
must include, as applicable: a direct URL to the FHIR capability 
statement, as defined by an unexpired version of the FHIR standard 
adopted in 45 CFR 170.215(a); and one or more URLs for a publicly 
accessible website with authorization and authentication protocols and 
implementation details; and API registration information.\210\ Each of 
those items are elements of the existing standards and documentation 
requirements that already must be publicly available.\211\

issuers on the FFEs. For the Provider Access and Payer-to-Payer

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

    The proposed URL reporting requirements directly correspond to 
existing requirements to make technical documentation publicly 
available, as follows:
    (1) FHIR Capability Statement--The capability statement can satisfy 
the existing requirements to make publicly accessible documentation 
that includes API syntax, function names, required and optional 
parameters supported and their data types, return variables and their 
types/structures, exceptions and exception handling methods and their 
returns.\212\ Because capability statements document API implementation 
details, functional capabilities, and operational parameters,

[[Page 19959]]

they should serve as a the primary source of technical documentation 
necessary to interact with the API.
---------------------------------------------------------------------------

    \212\ See 42 CFR 422.119(d)(1) for MA organizations, 42 CFR 
431.60(d)(1) for state Medicaid FFS programs, 42 CFR 457.730(d)(1)

CHIP managed care entities, and 45 CFR 156.221(d)(1) for QHP issuers 
on the FFEs.
---------------------------------------------------------------------------

    (2) Authorization and Authentication Protocols and Implementation 
Details--This documentation should satisfy the existing requirements to 
make publicly accessible all applicable technical requirements and 
attributes necessary for an app to be registered with any authorization 
server(s) deployed in conjunction with the API.\213\ Specific 
information about authorization and authentication protocols and 
implementation details is essential for developers to ensure that their 
software can communicate and exchange information with an API.

CHIP managed care entities, and 45 CFR 156.221(d)(3) for QHP issuers 
on the FFEs.
---------------------------------------------------------------------------

    (3) API Registration Information--This documentation can satisfy 
the requirements to make publicly accessible the software components 
and configurations an application must use in order to successfully 
interact with the API and process its response(s).\214\ Without 
registration procedures, developers cannot establish the necessary 
access credentials to use the APIs.
---------------------------------------------------------------------------

through cross reference to 42 CFR 438.242 in 42 CFR 457.1233(d) for 
CHIP managed care entities, and 45 CFR 156.221(d)(2) for QHP issuers 
on the FFEs.
---------------------------------------------------------------------------

    These three documentation types--capability statements, 
authorization and authentication protocols and implementation details, 
and API registration information--represent discrete components of the 
broader documentation already required under existing regulations. The 
proposed URL reporting requirements do not expand the scope of required 
documentation but rather add to existing requirements by establishing a 
standardized mechanism for verifying compliance and facilitating 
discoverable access to required documentation.
    The URL reporting proposal is integral to the effectiveness of API 
endpoint reporting. API endpoints are only functional when developers 
can access the technical documentation needed to integrate with them, 
including FHIR capability statements, authorization and authentication 
protocols and implementation details, and API registration information. 
Without discoverable documentation, centralized endpoint information 
provides limited value to the health care ecosystem. Both proposals, to 
report API endpoints and documentation URLs, could facilitate patient 
access to health information, support care coordination, enable 
efficient program administration, and reduce administrative burden on 
developers, providers, and payers.
    While impacted payers must already make API documentation publicly 
available under existing regulations, CMS currently lacks an efficient 
mechanism to systematically verify compliance and facilitate 
standardized discovery of this documentation across hundreds of payers. 
The URL reporting proposal could enable CMS to systematically verify 
that required documentation is publicly accessible, monitor ongoing 
compliance with existing documentation obligations, and identify 
compliance gaps more efficiently than manual discovery processes. This 
could transform fragmented compliance into systematic, verifiable 
accessibility that serves both regulatory oversight and industry needs. 
CMS cannot efficiently gather this information independently because 
doing so would require continuous monitoring of hundreds of payer 
websites across multiple programs (MA, Medicaid, CHIP, and QHPs on the 
FFEs), technical staff to locate and verify documentation across 
varying website structures, and ongoing maintenance as payers modify 
their websites. Manual discovery by CMS could result in outdated 
information, discovery delays, and verification challenges, while 
requiring disproportionate resource allocation compared to the benefit 
for the industry.
    This proposal explicitly addresses registration requirements that 
impacted payers must already meet. The proposed URL reporting 
requirements are authorized under the same statutory provisions that 
support the existing documentation requirements and would enable CMS to 
facilitate centralized discovery of documentation that must already be 
publicly available under existing regulations.\215\

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

    Maintaining API technology conformant with an unexpired version of 
the FHIR standard adopted in 45 CFR 170.215(a) is a requirement for all 
the interoperability APIs; and within that FHIR standard, capability 
statements are a mandatory resource. A capability statement documents 
how a FHIR API has been implemented, including the particular unexpired 
version of the FHIR standard, and which aspects of the standard have 
been implemented and how.\216\ The statement can be used to describe 
how to interface with the FHIR server and thus can provide a degree of 
self-configuration for software clients. For example, a capability 
statement could indicate whether the FHIR server allows clients to push 
updates to patient information, or which fields are searchable to find 
the appropriate patient. Furthermore, a thorough and accurate 
capability statement would help impacted payers meet their 
documentation requirements.\217\

CHIP managed care entities, and 45 CFR 156.221(d)(1) for QHP issuers 
on the FFEs.
---------------------------------------------------------------------------

    Because capability statements document API implementation details, 
functional capabilities, and operational parameters, they are a primary 
source technical documentation that could satisfy the requirement to 
make documentation that includes API syntax, function names, required 
and optional parameters, software components and configurations, and 
technical requirements for apps to interact with their APIs publicly 
accessible. Ensuring that direct URLs to capability statements are 
readily available for all payers in a centralized location would reduce 
developer burden to find each payer's capability statement. Reducing 
developer burden--whether for a developer of patient apps, EHRs, or 
payer systems--could expedite patient data exchange and lead to more 
timely and informed care. We emphasize that we are proposing that 
impacted payers would have to provide a direct URL to the capability 
statement itself and not to a documentation site that includes the 
capability statement. Because the capability statement is a structured 
file, we believe it is important that software be able to find it 
automatically without additional manual intervention to find

[[Page 19960]]

the file within a site reported by the payer.
    In addition, we propose to require impacted payers to report to CMS 
a URL or URLs with information about authorization and authentication 
protocols and implementation details for their API. That information is 
already required to be posted in a publicly accessible location by 
impacted payers, but we are now proposing to require impacted payers to 
report to CMS the location where they have made it 
available.218 219 Specific information about authorization 
and authentication protocols and implementation details is essential 
for developers to ensure that their software can communicate and 
exchange information with an API. Authorization is the process by which 
the server gives the requesting client permission to access data. 
Authentication protocols are those that a payer uses to verify the 
identity of the requesting entity. However, there is no single protocol 
for authentication that will address all use cases.\220\ Additionally, 
within a single API, implementers may need to utilize more than one 
protocol to address specific population and trading partner needs. 
Therefore, it is essential that developers know how to design their 
software, whether for patients, providers, or payers, to successfully 
access the appropriate data.
---------------------------------------------------------------------------

    \218\ Authorization and authentication protocols are ``software 
components and configurations an application must use in order to 
successfully interact with the API'' and are specifically required 
to be publicly posted in 42 CFR 422.119(d)(2) for MA organizations, 
42 CFR 431.60(d)(2) for state Medicaid FFS programs, 42 CFR 
457.730(d)(2) for state CHIP FFS programs, through cross reference 
to 42 CFR 431.60 in 42 CFR 438.242(b)(5) for Medicaid managed care 
plans, through cross reference to 42 CFR 438.242 in 42 CFR 
457.1233(d) for CHIP managed care entities, and 45 CFR 156.221(d)(2) 
for QHP issuers on the FFEs.
    \219\ Authorization protocols (such as OAuth 2.0 and SMART App 
Launch) define the software components and configurations that apps 
must implement to obtain permission to access data from the API 
server, including authorization clients, token handlers, and 
redirect URI configurations. Authentication protocols (such as 
OpenID Connect Core) define the software components and 
configurations that apps must implement to verify the identity of 
the requesting entity, including authentication flows, identity 
token processors, and user credential validation modules.

Security. Retrieved from https://hl7.org/fhir/security.html#binding.
---------------------------------------------------------------------------

    Often, API servers require apps or other software that interact 
with an API to be registered with the server and receive a key that 
verifies the app or program making the API call (API key).\221\ That 
allows the server to identify the app and ensure it has the access 
rights required to make the particular API call. API keys are not 
intended to fulfill the same security functions as authorization and 
authentication protocols for users, but they help payers monitor their 
APIs and gather data on usage. Because registration is sometimes 
necessary to connect to an API, if the payer requires registration, we 
propose to require impacted payers to report to CMS a public URL with 
information about how developers can register their apps with the API 
server. We are making those proposals in the CFR citations listed in 
Table 8. Not all APIs require registration. For example, the 2020 CMS 
Interoperability and Patient Access final rule (85 FR 25583 and 25584) 
established that provider directory information must be accessible via 
an API without requiring authentication. Therefore, payers implementing 
Provider Directory APIs would not have API registration information to 
report for that API, and the requirement would not apply.
---------------------------------------------------------------------------

    \221\ See, for example, the Certified Health IT Product Listing 
API maintained by ONC at https://chpl.healthit.gov/#/resources/api 
and the ONC Certification (g)(10) Standardized API Test Kit at 
https://github.com/onc-healthit/onc-certification-g10-test-kit?tab=readme-ov-file#terminology-prerequisites.
---------------------------------------------------------------------------

    We propose that CMS would publish those API endpoints and URLs in a 
centralized location for easy discovery by developers. We emphasize 
that we are not proposing that impacted payers would be required to 
report their supporting documentation itself to CMS. Rather, we are 
proposing that impacted payers would be required to report to CMS one 
or more public URLs where that documentation can be publicly accessed. 
However, we request comment on whether a single URL to a site that 
contains the authorization and authentication protocols and 
implementation details and API registration information is sufficient, 
or whether impacted payers should report a separate URL for each of 
these items. In addition, we request comment on whether there are 
discrete pieces of information, such as the specific authentication 
protocol a payer uses, that we should collect to facilitate faster API 
integration with patient health apps, provider EHRs, and payer systems. 
We wish to balance the benefits of making as much information available 
in a standardized and centralized location against the burden of 
reporting.
3. Alternative Proposal--National Directory of Healthcare Providers & 
Services Implementation Guide
    As an alternative to our primary proposal, the National Directory 
of Healthcare Providers & Services (NDH) IG could provide a framework 
for payers to report the proposed information.\222\ The NDH IG has been 
developed to facilitate and standardize a national directory 
infrastructure. The NDH IG provides a framework for standardized 
information sharing about providers, health organizations, and related 
services, their relationships, and technical connectivity details (for 
example, electronic endpoints) in FHIR. Within the NDH IG is an 
Endpoint Profile resource that has already been developed with the 
resource structure we are proposing for payer endpoint reporting.\223\ 
The Endpoint Profile within the NDH IG includes several of the data 
elements we are proposing here, as well as additional information for 
developers. The NDH IG Endpoint Profile includes extensions to document 
IG versions, authentication information, trust frameworks, UDAP dynamic 
registration, environment type (production/test/development), and more. 
While the NDH IG has not been adopted by HHS at this time, it may 
provide a simpler method for data submission, as it has been developed 
by FAST, an HL7 FHIR accelerator program, using the same FHIR standards 
as the other specifications and IGs discussed in this proposed rule. 
Tying reporting requirements to an existing FHIR IG may simplify the 
process for payers to report the proposed data and developers to use 
the data within a potential centralized registry.

Resource Profile: NDH Base Endpoint Profile. Retrieved from https://hl7.org/fhir/us/ndh/STU1/StructureDefinition-ndh-Endpoint.html.
---------------------------------------------------------------------------

    Under this alternative proposal, we propose to require impacted 
payers to report NDH IG Endpoint Profile compliant resources containing 
the relevant information for each interoperability API. A single 
Endpoint Resource would be sufficient for cases where a single endpoint 
manages multiple API types with the same server or service address 
(URL), requirements, and other documentation. Under this alternative 
proposal, impacted payers would be required to populate all elements 
and extensions identified in the profile that are relevant to the 
specific interoperability API, including, but not limited to: FHIR IGs 
and

[[Page 19961]]

versions, dynamic registration information, trust framework, secure 
exchange artifacts, access control mechanisms, payload Multipurpose 
internet Mail Extension (MIME) type, and environment type. This 
alternative proposal is limited to proposing to require impacted payers 
to submit relevant Endpoint Resources that are compliant with the NDH 
Endpoint Profile, as opposed to proposing to require full support and 
implementation of the NDH IG as a whole.
4. Reporting Timelines
    In the 2020 CMS Interoperability and Patient Access final rule, we 
finalized compliance dates in 2021 for the Patient Access and the 
Provider Directory APIs (except for QHP issuers on the FFEs, which are 
not subject to the Provider Directory API requirement) (85 FR 25558 and 
25559 and 85 FR 25563 and 25564). Therefore, the information we are 
proposing to require impacted payers to report to CMS should already be 
publicly available for those two APIs. In the 2024 CMS Interoperability 
and Prior Authorization final rule, we established compliance dates in 
2027 for impacted payers to implement the Provider Access, Payer-to-
Payer, and Prior Authorization APIs. We believe that it would benefit 
payers, providers, and patients to have endpoints publicly available as 
soon as possible. Therefore, rather than tying a compliance date to the 
beginning of a calendar year, plan year, or rating period, we are 
proposing that all impacted payers be required to report the proposed 
data to CMS no later than 60 days after the effective date of a final 
rule. The proposed information about their own APIs should be readily 
available to impacted payers. Therefore, we believe the benefits of 
making endpoints publicly available, as discussed here, compel an 
expedited reporting process and deadline.
    As new payers participate in CMS programs, we propose that they 
would be required to report the proposed information to CMS no later 
than 60 days before they begin covering patients under the applicable 
CMS program. Specifically, that means that a new impacted payer would 
be required to report 60 days before January 1 for MA organizations and 
state Medicaid and CHIP FFS programs, 60 days before the beginning of a 
rating period for Medicaid managed care plans or CHIP managed care 
entities, and 60 days before a plan year for QHP issuers on the FFEs, 
depending on the type of plan(s) the impacted payer is offering.
    After the proposed deadline, we propose that impacted payers would 
be required to update the information reported to CMS within 1 week of 
any changes. In addition, to ensure that the latest information is 
available, we propose that impacted payers would be required to verify 
that the reported information is still correct every 12 months from the 
date of the last update or verification. We believe that the burden of 
reporting API endpoints to CMS would be minimal compared to the burden 
on payers to individually locate other payers' API endpoints for the 
Payer-to-Payer API. We seek comment on the burden that reporting API 
endpoints could place on payers and how CMS can reduce that burden, 
either with the information we collect or the method of collection. 
Impacted payers could meet the proposed requirements to verify their 
information at any time during the year. For instance, we expect that 
QHP issuers could report (if a new QHP issuer) or verify every 12 
months (if an existing QHP issuer) at the same time they apply for 
certification on the FFEs, which could streamline their reporting 
requirements and allow CMS to verify that the QHP issuer has met the 
conditions for certification.
    While only impacted payers would be subject to these proposals, if 
finalized, CMS would collect and publish API endpoints and URLs from 
any payer that implements interoperability APIs, including those that 
are not impacted payers under the CMS interoperability rules. As we 
continue to strongly encourage payers not subject to our 
interoperability rules to participate in data exchange, according to 
the requirements and standards established in those rules, we would 
want to facilitate their participation by publishing their API 
endpoints and documentation URLs.
5. Publication
    While we are not making any proposals as to the specific methods, 
formats, or systems that could be used to collect and publish the 
proposed information, we seek comment on how CMS could do so in a 
manner that would balance the burden on payers with the benefits to 
developers, patients, providers, and payers.
6. Summary
    In summary, we request comment on our proposals in the CFR 
citations listed in Table 8, and specifically on the following:
     The proposal to require impacted payers to report all API 
endpoints to CMS, in the form of an Endpoint Resource, as defined by an 
unexpired version of the FHIR standard adopted in 45 CFR 170.215(a), 
including, if multiple, appropriate use cases for each.
     The proposal to require impacted payers to report URLs 
with the required documentation for each of their interoperability 
APIs, as applicable:
    ++ A direct URL to the API FHIR capability statement.
    ++ Authorization and authentication protocols and implementation 
details.
    ++ API registration information.
     The proposal to require impacted payers to report this 
information to CMS no later than 60 days after the effective date of a 
final rule.
     The proposal to require new impacted payers to report this 
information no later than 60 days before they begin covering patients 
under the applicable CMS program.
     The proposal to require impacted payers to update CMS 
within 1 week of any changes to the reported information and verify 
their information at least once every 12 months.
     The alternative proposal to require impacted payers to 
report to CMS all NDH IG Endpoint Profile resources containing the 
relevant information for each interoperability API.
    In addition, we request comment on the following:
     Is the proposal to collect a direct URL for the FHIR 
capability statements necessary, or would a payer endpoint be 
sufficient to indicate that the capability statement is located at [API 
endpoint]/metadata, as is required by the FHIR standard, or is that 
data element duplicative?
     Whether a single URL to a site that contains the 
authorization and authentication protocols and implementation details, 
and API registration information is sufficient, or whether impacted 
payers should report separate direct URLs for each of these items?
     Whether there are discrete pieces of information, such as 
the specific authentication protocol a payer uses, that we should 
collect to facilitate faster API integration with patient health apps, 
provider EHRs, and payer systems?
     Would aligning the reporting requirements with the NDH 
Endpoint Profile resource reduce payer burden to report the proposed 
information and/or developer burden to use a centralized registry?
     If the alternative proposal is finalized, would it negate 
the need for impacted payers to report URLs to documentation related to 
authorization and authentication protocols and implementation details 
and API registration information?

[[Page 19962]]

     The burden that reporting API endpoints could place on 
payers and how CMS can reduce that burden, either with the information 
we collect or the method of collection.
     How CMS could collect and publish the reported information 
in a manner that would balance the burden on payers with the benefits 
to developers, patients, providers, and payers. For example:
    ++ Would a machine-readable file on CMS's website be sufficient?
    ++ What would the benefits be of a FHIR-enabled registry, either 
for reporting or publishing? Would using FHIR standards allow a more 
streamlined and automated reporting process for payers? Would it allow 
greater flexibility for third-party app developers and EHR developers, 
which could improve the patient and provider experience?

BILLING CODE 4150-28-C
7. Statutory Authorities
a. Medicare Advantage
    For MA organizations, we are proposing these new requirements under 
our authority in the following sections of the Act:
     Section 1852(d)(1)(A) of the Act requires MA organizations 
offering an MA plan to, as a condition of using a network of providers, 
make covered benefits available and accessible to enrollees in a manner 
that assures continuity in the provision of benefits.
     Section 1852(g)(1)(A) of the Act requires an MA 
organization to have a procedure for making determinations about 
whether an enrollee is entitled to receive a health service, how much 
the enrollee is required to pay for such service, and to provide an 
enrollee with a written notice if the plan denies coverage. Section 
1852(g)(1)(A) of the Act also requires that coverage determinations be 
made on a timely basis.
     Section 1852(h) of the Act requires that MA organizations 
have procedures in place to maintain accurate and timely medical 
records and other health information regarding MA enrollees and to 
assure enrollees have timely access to such records and information.
     Section 1856(b) of the Act authorizes the Secretary to 
establish regulatory standards for MA organizations that are consistent 
with and carry out Part C of the Medicare statute, including the 
provisions in section 1852 of the Act.
     Section 1857(e)(1) of the Act explicitly authorizes the 
adoption of additional MA contract terms and conditions, including 
required reporting to CMS by MA organizations, where necessary and 
appropriate and not inconsistent with Part C of the Medicare statute.
    One-Week Update Requirement--Section 1857(e)(1) of the Act 
explicitly authorizes additional contract terms and conditions, 
including required reporting to CMS by MA organizations, where 
necessary and appropriate. The proposed 1-week update requirement is 
necessary to ensure that the centralized registry maintains current 
endpoint information that supports the statutory requirements in 
sections 1852(d)(1)(A) (continuity of care), 1852(g)(1)(A) (timely 
coverage determinations), and 1852(h) (timely access to health records) 
of the Act. Section 1856(b) of the Act authorizes regulatory standards 
that carry out Part C requirements. Timely endpoint updates are 
essential to maintain the effectiveness of these statutory obligations, 
as outdated endpoints immediately disrupt API functionality and 
undermine patient access and care coordination.
    Verification Requirement--The proposed requirement to verify every 
12 months is necessary and appropriate to ensure ongoing compliance 
with API endpoint reporting obligations and the underlying statutory 
requirements they support, and therefore may be adopted by the 
Secretary as an additional MA contract term under section 1857(e)(1) of 
the Act. In addition, section 1856(b) of the Act authorizes the 
Secretary to establish standards that ensure continued compliance with 
statutory requirements, including verification that reported 
information remains accurate to support ongoing patient access and care 
coordination.
    API URL Reporting--The proposed requirement for MA organizations to 
report URLs for API documentation is supported by the same statutory 
authorities as the 1-week update and verification requirements. Section 
1857(e)(1) of the Act authorizes additional contract terms including 
required reporting to CMS where necessary and appropriate to effectuate 
the interoperability API requirements established under sections 
1852(d)(1)(A), 1852(g)(1)(A), and 1852(h) of the Act. Section 1856(b) 
of the Act supports the URL reporting proposal as a regulatory standard 
necessary to ensure that technical information required for API 
functionality is discoverable, supporting timely patient access to 
health records, continuity of care, and coverage determinations. 
Without discoverable documentation, the API endpoints themselves cannot 
function effectively to serve these statutory purposes.
    Patient Access API--If developers have to find payer API endpoints 
individually, it could result in delays to the enrollee's ability to 
access their records in a timely manner. Therefore, we propose to 
collect and publish payer API endpoints under our authority under 
section 1856(b) of the Act to establish standards to carry out section 
1852(h), as well as our authority under section 1857(e)(1) of the Act. 
Facilitating patients' access to their own health information could 
allow them to identify errors or missing data, thus improving the 
accuracy and timeliness of the medical records maintained by the MA 
organization. In the 2024 CMS Interoperability and Prior Authorization 
final rule, we stated that making these data available through the 
Patient Access API is consistent with our programmatic authority to 
establish standards to implement section 1852(h) of the Act and could 
help patients be more informed about and active in their own care, 
which could potentially lead to better health outcomes.\224\
---------------------------------------------------------------------------

    \224\ See 89 FR 8784.
---------------------------------------------------------------------------

    Provider Access API--Without a centralized location for providers 
to find API endpoints, the increased burden may lead to delays in 
receiving patient data, or providers deciding not to request patient 
data at all. Therefore, we propose to collect and publish payer API 
endpoints under our authority under section 1856(b) of the Act to 
establish standards to carry out sections 1852(d)(1)(A) and 1852(h) of 
the Act, as well as our authority under 1857(e)(1) of the Act. 
Facilitating providers' access to patient data would give insight into 
health history and previous care, thus creating conditions for benefits 
to be accessible in a manner that assures the continuity of care. As 
discussed in the 2024 CMS Interoperability and Prior Authorization 
final rule, the Provider Access API would facilitate exchanges of 
information about enrollees that are necessary for effective and 
continuous patient care, which is consistent with the requirement at 
section 1852(d)(1)(A) of the Act for continuing the provision of 
benefits.\225\
---------------------------------------------------------------------------

    \225\ See 89 FR 8818.
---------------------------------------------------------------------------

    Payer-to-Payer API--One of the most important purposes of our payer 
to payer data exchange policy is to facilitate care continuity at the 
time a patient changes payers. Delays in being able to find the 
previous payer's API endpoint to request patient data could diminish 
those benefits. Therefore, we propose to collect and publish payer API 
endpoints under our authority under section 1856(b) of the Act to 
establish standards to carry out section 1852(d)(1)(A), as well as our 
authority under section 1857(e)(1) of the Act. Per the 2024 CMS 
Interoperability and Prior Authorization final rule, impacted payers 
are required to make a ``reasonable effort to locate information about 
a patient's previous payer,'' including that payer's API 
endpoints.\226\ Requiring impacted payers to report their API endpoints 
would ease the burden of finding other payers' endpoints, thus 
potentially leading to more payer to payer data exchange as envisioned 
by the CMS interoperability regulations.
---------------------------------------------------------------------------

    \226\ See 89 FR 8840 and 8841.
---------------------------------------------------------------------------

    Prior Authorization API--Collecting and publishing payer API 
endpoints would allow developers to configure provider systems to 
dynamically find and use the appropriate payer's API endpoint rather 
than hard coding each payer API endpoint or requiring a provider to 
find the API endpoint

[[Page 19966]]

themselves to submit a prior authorization request. Such process 
barriers could result in untimely delays to patient care and negate 
some of the benefits that the Prior Authorization API would provide. 
Therefore, we propose to collect and publish payer API endpoints under 
our authority under section 1856(b) of the Act to establish standards 
to carry out section 1852(g)(1)(A), as well as our authority under 
section 1857(e)(1) of the Act. Reporting API endpoints would facilitate 
the required procedure for making determinations about enrollee 
benefits and costs, which would lead to more timely coverage 
determinations.
    Provider Directory API--Collecting and publishing payer API 
endpoints for Provider Directory APIs could facilitate provider and 
patient access to current, accurate provider network information. 
Without centralized endpoint discovery, providers and patients face 
increased burden in locating and accessing provider directory 
information, which could delay care coordination and patient access to 
in-network providers. Therefore, we propose to collect and publish 
payer API endpoints under our authority under section 1856(b) of the 
Act to establish standards to carry out section 1852(d)(1)(A), as well 
as our authority under section 1857(e)(1) of the Act. Facilitating 
access to provider directory information supports the requirement that 
MA organizations make covered benefits available and accessible in a 
manner that assures continuity in the provision of benefits.
b. Medicaid
    For state Medicaid FFS programs and Medicaid managed care plans, we 
are proposing these new requirements under our authority in the 
following sections of the Act:
     Section 1902(a)(4) of the Act requires that a state 
Medicaid plan provides such methods of administration as are found by 
the Secretary to be necessary for the proper and efficient operation of 
the state Medicaid plan, which includes ensuring that contracted 
managed care plans comply with federal interoperability requirements.
     Section 1902(a)(6) of the Act requires states to make 
reports in a form and containing information required by the Secretary, 
which can include ensuring that managed care plans under contract 
provide necessary endpoint information to the state for reporting to 
CMS.
     Section 1902(a)(8) of the Act requires states to ensure 
that Medicaid services are furnished with reasonable promptness to all 
eligible individuals.
     Section 1902(a)(19) of the Act requires states to ensure 
that care and services are provided in a manner consistent with 
simplicity of administration and the best interests of the recipients.
     Section 1903(m)(2)(A)(xi) of the Act requires that 
contracts with Medicaid MCOs include provisions that ensure compliance 
with applicable requirements. This provides direct authority to impose 
endpoint reporting requirements on managed care plans through their 
contracts with states.
     Section 1932(a) of the Act provides authority for states 
to implement managed care arrangements and includes certain waiver 
provisions. Section 1932(d)(1) of the Act establishes that managed care 
entities must comply with requirements the Secretary determines 
necessary to carry out the purposes of the Medicaid program
    One-Week Update Requirement--Section 1902(a)(6) of the Act requires 
states to make reports ``in a form and containing information required 
by the Secretary,'' which includes the timing and frequency of such 
reports. The proposed 1-week update requirement ensures that CMS 
receives timely information necessary for proper program oversight. 
Section 1902(a)(4) of the Act requires methods of administration 
necessary for proper and efficient program operation. Outdated endpoint 
information could undermine the efficient operation of the Medicaid 
program by disrupting API functionality that supports beneficiary 
access to care and data.
    Verification Requirement--Section 1902(a)(6) of the Act supports 
verification every 12 months as part of the reporting requirements 
necessary for proper program oversight and monitoring. Section 
1902(a)(4) of the Act requires ongoing administrative methods that 
ensure proper program operation, which includes verifying the accuracy 
of reported endpoint information that supports beneficiary services.
    API URL Reporting--Section 1902(a)(6) of the Act supports the URL 
reporting proposal as part of the reporting requirements necessary for 
CMS to facilitate the interoperability framework established under our 
Medicaid API requirements. This also directly supports requiring states 
to collect and report API endpoint information from both their FFS 
programs and contracted managed care plans. Section 1902(a)(4) of the 
Act requires this as a method of administration necessary for proper 
and efficient program operation, as centralized documentation discovery 
supports efficient API implementation and reduces administrative burden 
on providers and developers. Additionally, section 1902(a)(4) of the 
Act requires states to ensure proper administration of their Medicaid 
programs, which includes oversight of managed care plan compliance with 
federal requirements, including endpoint reporting. States have 
existing obligations to monitor and ensure managed care plans' 
compliance with federal requirements, and endpoint reporting falls 
within this oversight responsibility. Section 1902(a)(19) of the Act 
supports this requirement as consistent with simplicity of 
administration and beneficiary interests, as centralized URLs simplify 
API integration and serve beneficiary interests in data access and care 
coordination.
    Patient Access API--We finalized the Patient Access API based on 
our authority in sections 1902(a)(4) and (a)(19) of the Act. The 
requirement to make Medicaid patients' health information available 
through interoperable technology can facilitate beneficiary access to 
their information in a convenient, timely, and portable way, which is 
essential for these programs to be effectively and efficiently 
administered in the best interests of beneficiaries. We have received 
feedback from developers that when they have to find payer API 
endpoints individually, it can delay beneficiaries' access to their 
records. Making these API endpoints publicly accessible through a 
centralized registry could further enhance beneficiary access by 
enabling broader innovation in third-party apps and reducing barriers 
for developers to create patient-friendly tools that help beneficiaries 
interact with their health information. As explained in the 2020 CMS 
Interoperability and Patient Access final rule, giving beneficiaries 
access to their own health data is necessary for the proper and 
efficient administration of the state plan.\227\ Therefore, we propose 
to collect and publish payer API endpoints under our authority in 
sections 1902(a)(4), (6), and (19) of the Act.
---------------------------------------------------------------------------

    \227\ See 85 FR 25526.
---------------------------------------------------------------------------

    Provider Access API--Collecting and publishing payer API endpoints 
would decrease provider burden, which may facilitate a provider's 
ability to request patient information. Otherwise, there could be 
delays in receiving patient information or a provider may decide not to 
request patient data due to that burden. Making patient health 
information available to providers at the point of care can 
significantly improve

[[Page 19967]]

their ability to render Medicaid services effectively, efficiently, and 
appropriately. The Provider Access API policies should help states 
fulfill their obligations to operate their state plans efficiently and 
to ensure that Medicaid services are furnished with reasonable 
promptness and in a manner consistent with the best interest of the 
recipients.\228\ Therefore, we propose to collect and publish payer API 
endpoints under our authority in sections 1902(a)(4), (6), and (19) of 
the Act.
---------------------------------------------------------------------------

    \228\ See 89 FR 8785.
---------------------------------------------------------------------------

    Payer-to-Payer API--Collecting and publishing payer API endpoints 
would decrease payer burden to locate payer API endpoints to make a 
request for patient data. That would accelerate payers' ability to make 
a timely request for patient data, at a point when delays could lead to 
gaps in care. Those data can provide the information necessary to 
ensure the beneficiary has timely continuity of care. Therefore, we 
propose to collect and publish payer API endpoints under our authority 
in sections 1902(a)(4), (6), (8), and (19) of the Act. Per the 2024 CMS 
Interoperability and Prior Authorization final rule, impacted payers 
are required to make a ``reasonable effort to locate information about 
a patient's previous payer,'' including that payer's API 
endpoints.\229\ Requiring impacted payers to report their API endpoints 
would ease the burden of finding other payers' endpoints, thus 
potentially leading to more payer to payer data exchange as envisioned 
by the CMS interoperability regulations.
---------------------------------------------------------------------------

    \229\ See 89 FR 8840 and 8841.
---------------------------------------------------------------------------

    Prior Authorization API--As explained in the 2024 CMS 
Interoperability and Prior Authorization final rule, the Prior 
Authorization API should improve the efficiency and timeliness of the 
prior authorization process for Medicaid beneficiaries, providers, 
state Medicaid agencies, and Medicaid managed care plans by addressing 
inefficiencies that exist today.\230\ Collecting and publishing payer 
API endpoints would allow developers to configure provider systems to 
dynamically find and use the appropriate payer's API endpoint rather 
than hard coding each payer API endpoint, which may create maintenance 
burdens and system fragility, or requiring a provider to find the API 
endpoint themselves to submit a prior authorization request. Doing so 
would significantly improve the efficiency and timeliness of the prior 
authorization process, which would ensure that Medicaid services are 
furnished with reasonable promptness to all eligible individuals. 
Therefore, we propose to collect and publish payer API endpoints under 
our authority in sections 1902(a)(4), (6), (8), and (19) of the Act.
---------------------------------------------------------------------------

    \230\ See 89 FR 8899.
---------------------------------------------------------------------------

    Provider Directory API--We propose to collect and publish Provider 
Directory API endpoints under our authority in sections 1902(a)(4), 
(6), and (19) of the Act. Section 1902(a)(4) of the Act requires states 
to provide methods of administration necessary for the proper and 
efficient operation of state Medicaid plans. Collecting and publishing 
Provider Directory API endpoints constitutes such a method of 
administration because it enables systematic verification of API 
accessibility and compliance monitoring. Section 1902(a)(6) of the Act 
requires states to make reports in a form and containing information 
required by the Secretary, which includes the timing and frequency of 
such reports. This authority supports the proposed requirement for 
impacted payers to report Provider Directory API endpoints, update CMS 
within 1 week of changes, and verify information every 12 months. 
Section 1902(a)(19) of the Act requires states to provide safeguards to 
ensure that care and services will be provided in a manner consistent 
with simplicity of administration and the best interests of recipients. 
Centralized endpoint discovery would serve the best interests of 
Medicaid beneficiaries by facilitating access to accurate provider 
directory information, which supports beneficiaries' ability to locate 
in-network providers and make informed health care decisions. 
Therefore, we propose to collect and publish Provider Directory API 
endpoints under our authority in sections 1902(a)(4), (6), and (19) of 
the Act.
c. CHIP
    For state CHIP FFS programs and CHIP managed care entities, we are 
proposing these new requirements under our authority in the following 
sections of the Act:
     We finalized the interoperability APIs under our general 
authority in section 2101(a) of the Act, which sets forth that the 
purpose of Title XXI is to provide funds to states to provide child 
health assistance to uninsured, low-income children in an effective and 
efficient manner that is coordinated with other sources of health 
benefits coverage.
     Section 2107(b)(1) of the Act requires state CHIP agencies 
to collect data, maintain records, and furnish reports in order to 
enable the Secretary to monitor state program administration and 
compliance and to evaluate and compare the effectiveness of state plans 
under this title.
    One-Week Update and Verification Requirements--Section 2107(b)(1) 
of the Act requires data collection and reporting to enable monitoring 
and evaluation. Timely endpoint updates are necessary for CMS to 
effectively monitor API implementation and ensure continued program 
effectiveness. Verification every 12 months is necessary for ongoing 
program monitoring and evaluation of API effectiveness.
    API URL Reporting--Section 2107(b)(1) of the Act supports URL 
reporting as necessary data collection and reporting to enable CMS to 
monitor effective API implementation and evaluate program success. 
Section 2101(a) of the Act establishes the purpose of providing child 
health assistance in an effective and efficient manner, and centralized 
documentation discovery supports efficient API implementation that 
benefits CHIP beneficiaries by facilitating seamless data exchange and 
care coordination.
    Patient Access API--Requiring state CHIP FFS programs to make 
beneficiaries' health information available through interoperable 
technology increases patient access to their health information, which 
can improve the efficacy of state CHIP FFS programs, allow for more 
efficient communication and administration of services, and promote 
coordination across various sources of health benefits coverage. As we 
stated in the 2024 CMS Interoperability and Prior Authorization final 
rule, the Patient Access API should increase patient access to their 
health information, which can improve the efficacy of state CHIP FFS 
programs, allow for more efficient communication and administration of 
services, and promote coordination across various sources of health 
benefits coverage.\231\ If developers have to find payer API endpoints 
individually, it could result in delays to the beneficiaries' ability 
to access their records in a timely manner. Therefore, we propose to 
collect and publish payer API endpoints under our authority in section 
2107(b)(1) of the Act to help state CHIP FFS programs provide coverage 
to low-income children more effectively and efficiently.
---------------------------------------------------------------------------

    \231\ See 89 FR 8786.
---------------------------------------------------------------------------

    Provider Access API--The more information a provider has to make 
informed decisions about a patient's care, the more likely it is that 
patients will receive care that best meets their needs. As explained in 
the 2024 CMS

[[Page 19968]]

Interoperability and Prior Authorization final rule, providers can be 
more effective and efficient in their delivery of CHIP services by 
having direct access to patient utilization and authorization 
information.\232\ If a provider has information about a patient prior 
to or at the point of care, the provider will be able to spend more 
time focused on the patient, rather than on their need to collect 
information. Therefore, we propose to collect and publish payer API 
endpoints under our authority in section 2107(b)(1) of the Act to help 
state CHIP FFS programs provide child health assistance to uninsured, 
low-income children in an effective and efficient manner.
---------------------------------------------------------------------------

    \232\ See 89 FR 8819.
---------------------------------------------------------------------------

    Payer-to-Payer API--The Payer-to-Payer API is central to the goal 
of coordination with other sources of health benefits coverage for 
children in section 2101(a) of the Act. Centralizing payer API 
endpoints could facilitate more efficient and accurate requests for 
patient information, faster data exchange, and ultimately better care 
continuity and coordination for CHIP beneficiaries as they enter or 
exit CHIP coverage. Therefore, we propose to collect and publish payer 
API endpoints under our authority in section 2101(a) of the Act to help 
state CHIP agencies provide child health assistance to uninsured, low-
income children in an effective and efficient manner that is 
coordinated with other sources of health benefits coverage. Per the 
2024 CMS Interoperability and Prior Authorization final rule, impacted 
payers are required to make a ``reasonable effort to locate information 
about a patient's previous payer,'' including that payer's API 
endpoints.\233\ Requiring impacted payers to report their API endpoints 
would ease the burden of finding other payers' endpoints, thus 
potentially leading to more payer to payer data exchange as envisioned 
by the CMS interoperability regulations.
---------------------------------------------------------------------------

    \233\ See 89 FR 8840 and 8841.
---------------------------------------------------------------------------

    Prior Authorization API--The Prior Authorization API facilitates 
the more efficient and effective exchange of information required to 
submit a prior authorization request and receive a decision. An 
improved process may reduce administrative costs for providers and 
payers and improve timeliness in responding to providers and patients. 
As explained in the 2024 CMS Interoperability and Prior Authorization 
final rule, making this information available in a standardized way and 
permitting access through an API will also serve the requirements in 
section 2101(a) of the Act that state CHIP agencies ensure access to 
coverage and coordinated care.\234\ Collecting and publishing payer API 
endpoints would allow developers to configure provider systems to 
dynamically find and use the appropriate payer's API endpoint rather 
than hard coding each payer API endpoint or requiring a provider to 
find the API endpoint themselves to submit a prior authorization 
request. Therefore, we propose to collect and publish payer API 
endpoints under our authority in section 2107(b)(1) of the Act to help 
state CHIP agencies provide child health assistance to uninsured, low-
income children in an effective and efficient manner.
---------------------------------------------------------------------------

    \234\ See 89 FR 8900.
---------------------------------------------------------------------------

    Provider Directory API--Centralizing Provider Directory API 
endpoints could facilitate more efficient access to provider network 
information, supporting the coordination of care with other sources of 
health benefits coverage as required under section 2101(a) of the Act. 
This would help state CHIP agencies provide child health assistance in 
an effective and efficient manner that is coordinated with other 
coverage sources. Therefore, we propose to collect and publish payer 
API endpoints under our authority in sections 2101(a) and 2107(b)(1) of 
the Act.
d. Qualified Health Plan Issuers on the Federally-facilitated Exchanges
    For QHP issuers on the FFEs, we finalized the API requirements 
under our authority in section 1311(e)(1) of the Affordable Care Act. 
Section 1311(e)(1)(A) of the Affordable Care Act requires that 
Exchanges only certify plans as QHPs if they meet the requirements for 
certification promulgated by the Secretary under section 1311(c)(1) of 
the Affordable Care Act, while section 1311(e)(1)(B) of the Affordable 
Care Act affords the Exchanges the discretion to certify QHPs if the 
Exchange determines that making available such health plans through the 
Exchange is in the interests of qualified individuals and qualified 
employers in the state or states in which such Exchange operates.
    One-Week Update and Verification Requirements--Section 
1311(e)(1)(B) of the Affordable Care Act provides discretion to certify 
QHPs if the Exchange determines that making such plans available is in 
the interests of qualified individuals and qualified employers in the 
state or states in which such Exchange operates. Maintaining current 
endpoint information through timely updates would serve these interests 
by ensuring reliable API access for enrollees--enabling them to access 
their health data, coordinate care with providers, and facilitate 
seamless data exchange between payers without delays caused by outdated 
or inaccessible API endpoints. Verification every 12 months would 
ensure that certified QHPs continue to serve the interests of qualified 
individuals and qualified employers through reliable, accessible API 
endpoints.
    API URL Reporting--Section 1311(e)(1)(B) of the Affordable Care Act 
provides discretion to certify QHPs if the Exchange determines that 
making such plans available is in the interests of qualified 
individuals and qualified employers in the state or states in which 
such Exchange operates. The proposal to require URL reporting ensures 
that certified QHPs maintain discoverable API documentation, serving 
enrollee interests in data access and care coordination. We believe it 
is in the interest of qualified individuals for health plans provide 
accessible technical documentation that enables effective API 
integration and operation.
    Patient Access API--In the 2020 CMS Interoperability and Patient 
Access final rule, we stated that generally certifying only health 
plans that make enrollees' health information available to them in a 
convenient, timely, and portable way is in the interests of enrollees 
in the state or states in which a FFE operates (85 FR 25526). If 
developers have to manually locate payer API endpoints individually, it 
could introduce operational inefficiencies and development delays that 
may hinder the enrollee's timely access to their records. Therefore, we 
propose to collect and publish payer API endpoints under our authority 
in section 1311(e)(1)(B) of the Affordable Care Act, as we believe it 
is in the interest of qualified individuals and qualified employers to 
collect and publish QHP issuers on the FFEs' API endpoints.
    Provider Access API--In the 2024 CMS Interoperability and Prior 
Authorization final rule, we stated that it is in the interest of 
enrollees to generally only certify health plans that make enrollees' 
health information available to their providers via the Provider Access 
API (89 FR 8820). Giving providers access to their enrollees' health 
information supplied by QHP issuers on the FFEs should ensure that 
providers are better positioned to provide enrollees with seamless and 
coordinated care and ensure that enrollees are not subject to duplicate 
testing and procedures, and delays in care and diagnosis. Access to the 
enrollee's more complete medical information could also maximize the 
efficiency of an enrollee's office visits.

[[Page 19969]]

Without a centralized location to find payer API endpoints, the 
increased burden may lead to delays in receiving enrollee information 
or providers deciding not to request enrollee data at all. Therefore, 
we propose to collect and publish payer API endpoints under our 
authority in section 1311(e)(1)(B) of the Affordable Care Act, as we 
believe it is in the interest of qualified individuals and qualified 
employers to collect and publish QHP issuers on the FFEs' API 
endpoints.
    Payer-to-Payer API--In the 2024 CMS Interoperability and Prior 
Authorization final rule, we stated that it is in the interest of 
enrollees to generally only certify health plans that have a Payer-to-
Payer API in place to exchange information with other payers about new 
enrollees, concurrent enrollees, and enrollees who have moved to 
another payer (89 FR 8858). Having enrollee information at the 
beginning of a new plan may assist the new payer in identifying 
enrollees who need care management services, which could reduce the 
cost of care. Delays in being able to find the previous payer's API 
endpoint to request enrollee data could diminish those benefits. Per 
the 2024 CMS Interoperability and Prior Authorization final rule, 
impacted payers are required to make a ``reasonable effort to locate 
information about a patient's previous payer,'' including that payer's 
API endpoints.\235\ Requiring impacted payers to report their API 
endpoints would ease the burden of finding other payers' endpoints, 
thus potentially leading to more payer to payer data exchange as 
envisioned by the CMS interoperability regulations. Therefore, we 
propose to collect and publish payer API endpoints under our authority 
in section 1311(e)(1)(B) of the Affordable Care Act, as we believe it 
is in the interest of qualified individuals and qualified employers to 
collect and publish QHP issuers on the FFEs' API endpoints.
---------------------------------------------------------------------------

    \235\ See 89 FR 8840 and 8841.
---------------------------------------------------------------------------

    Prior Authorization API--In the 2024 CMS Interoperability and Prior 
Authorization final rule, we stated that it is in the interest of 
enrollees for CMS to generally only certify health plans that have a 
Prior Authorization API because it enables more accurate submission and 
processing of prior authorization requests, which could improve the 
delivery of services to enrollees (89 FR 8901). Collecting and 
publishing payer API endpoints would allow developers to configure 
provider systems to dynamically find and use the appropriate payer's 
API endpoint rather than hard coding each payer API endpoint or 
requiring a provider to find the API endpoint themselves to submit a 
prior authorization request. We believe that in reducing provider 
administrative burden, providers would spend less time on 
administrative tasks, allowing them to spend more time on enrollee 
care. Therefore, we propose to collect and publish payer API endpoints 
under our authority in section 1311(e)(1)(B) of the Affordable Care 
Act, as we believe it is in the interest of qualified individuals and 
qualified employers to collect and publish QHP issuers on the FFEs' API 
endpoints.
    Provider Directory API--QHP issuers on the FFEs are not subject to 
Provider Directory API requirements.

F. Updates to Patient Access, Provider Directory, Provider Access, and 
Payer-to-Payer APIs; API Usage Metrics

1. Information About Prior Authorizations for Drugs in the Patient 
Access, Provider Access, and Payer-to-Payer APIs
a. Background
    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we required impacted payers to make available certain information 
about prior authorizations for non-drug items and services via a 
Patient Access API.\236\ We also required impacted payers to make 
available similar information via Provider Access and Payer-to-Payer 
APIs (89 FR 8817 and 8855). We finalized compliance dates beginning in 
2027 for each of these APIs (by January 1, 2027 for MA organizations 
and state Medicaid and CHIP FFS programs; by the rating period 
beginning on or after January 1, 2027 for Medicaid managed care plans 
and CHIP managed care entities; and for plan years beginning on or 
after January 1, 2027 for individual market QHP issuers on the FFEs) 
(89 FR 8784, 8817, and 8855). Specifically, impacted payers must make 
all of the following information available about prior authorization 
requests and decisions for non-drug items and services via the Patient 
Access and Provider Access APIs:
---------------------------------------------------------------------------

    \236\ See 42 CFR 422.119(b)(1)(iv)(A) for MA organizations, 42 
CFR 431.60(b)(5)(i) for state Medicaid FFS programs, 42 CFR 
457.730(b)(5)(i) for state CHIP FFS programs, through cross 
reference to 42 CFR 431.60 in 42 CFR 438.242(b)(5) for Medicaid 
managed care plans, through cross reference to 42 CFR 438.242 in 42 
CFR 457.1233(d) for CHIP managed care entities, and 45 CFR 
156.221(b)(1)(iv)(A) for individual market QHP issuers on the FFEs.
---------------------------------------------------------------------------

     The prior authorization status.
     The date the prior authorization was approved or denied.
     The date or circumstance under which the prior 
authorization ends.
     The items and services approved.
     If denied, a specific reason why the request was denied.
     Related structured administrative and clinical 
documentation submitted by a provider (89 FR 8784 and 8817).
    Impacted payers must make the same prior authorization information 
available through the Payer-to-Payer API, except they are not required 
to include denied prior authorizations (or a specific reason why the 
request was denied).\237\ Additionally, impacted payers must make 
available via the Payer-to-Payer API both structured and unstructured 
administrative and clinical documentation submitted by a provider.\238\ 
For each of these APIs--the Patient Access, Provider Access, and Payer-
to-Payer APIs (collectively ``Access APIs''), we required that impacted 
payers make this information about prior authorizations available no 
later than 1 business day after the payer receives a prior 
authorization request and must update that information no later than 1 
business day after any status change. This information must be 
available for the duration that the authorization is active and at 
least 1 year after the prior authorization's last status change (89 FR 
8784, 8817, and 8855). Like the rest of the 2024 CMS Interoperability 
and Prior Authorization final rule, those requirements do not apply to 
any kind of drugs.

b. Proposals
    We emphasize the importance of access to prior authorization 
information for drugs in section II.B. of this proposed rule. For the 
reasons we explained in that section and in response to public feedback 
received on the 2022 CMS Interoperability and Prior Authorization 
proposed rule, we propose to add information about prior authorization 
requests and decisions for all drugs to the categories of data impacted 
payers are required to make available through the Access APIs. We 
propose to amend the Access API

[[Page 19970]]

provisions that require impacted payers to make available information 
about prior authorizations for non-drug items and services and drugs. 
Consistent with our policies for non-drug items and services, the 
information about prior authorizations for drugs that we are proposing 
be made available via the Patient Access and Provider Access APIs is 
the following:
     The prior authorization status.
     The date the prior authorization was approved or denied.
     The date or circumstance under which the prior 
authorization ends.
     The drug or drugs approved (including the dosage).
     If denied, a specific reason why the request was denied.
     Related structured administrative and clinical 
documentation submitted by a provider.
    For the Payer-to-Payer API, the information about prior 
authorizations for drugs we propose is the following:
     The prior authorization status.
     The date the prior authorization was approved.
     The date or circumstance under which the prior 
authorization ends.
     The drug or drugs approved (including the dosage).
     Related structured and unstructured administrative and 
clinical documentation submitted by a provider.
    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we excluded denied prior authorization requests for non-drug 
items and services from the set of information that must be exchanged 
between payers via the Payer-to-Payer API and are proposing the same 
for prior authorizations for drugs (89 FR 8827). We propose to exclude 
denied prior authorization requests because they generally would not 
reflect ongoing treatment, as it does not demonstrate that patients 
actually received items, services, or drugs. If a patient ultimately 
received those items, services, or drugs despite the denied request, 
that information would have to be gathered from elsewhere (such as 
clinical data), regardless of whether the requesting payer receives 
information about the prior authorization decision. Many commenters 
cited similar justifications for excluding denied prior authorizations 
in response to the 2022 CMS Interoperability and Prior Authorization 
proposed rule, and we thus did not finalize a requirement to include 
denied prior authorization decisions in the Payer-to-Payer API 
policies. The value of including such information would likely be 
outweighed by the additional burden on impacted payers to include it 
and we therefore believe its exclusion remains justified. We refer 
readers to the 2024 CMS Interoperability and Prior Authorization final 
rule for a full discussion of our reasoning for this exclusion (89 FR 
8830).
    We propose an October 1, 2027 compliance date for MA organizations, 
state Medicaid and CHIP FFS programs, Medicaid managed care plans, CHIP 
managed care entities, and QHP issuers on the FFEs to make the proposed 
information about prior authorizations for drugs available via the 
Access APIs. Because impacted payers are already required to make 
available information about prior authorizations for non-drug items and 
services beginning in 2027 (by January 1, 2027, for MA organizations 
and state Medicaid and CHIP FFS programs; by the rating period 
beginning on or after January 1, 2027, for Medicaid managed care plans 
and CHIP managed care entities; and for plan years beginning on or 
after January 1, 2027, for QHP issuers on the FFEs) (89 FR 8784, 8817, 
and 8855), we believe a 9-month implementation window following that 
date strikes the appropriate balance between urgency and operational 
feasibility. An October 1, 2027 compliance date allows impacted payers 
to build upon the infrastructure and processes established for the 
January 1, 2027 deadline, while providing a defined period to extend 
that infrastructure to drug prior authorization data. However, we 
encourage these payers to make this information available via their 
APIs as soon as possible to benefit their patients.
    We propose that the requirement to make available information about 
prior authorization for drugs would be subject to the same timeframes 
established for making available prior authorization information for 
non-drug items and services--no later than 1 business day after the 
payer receives a prior authorization request--and the payer must update 
that information no later than 1 business day after any status change. 
This proposal not only aligns with our previously finalized policy, but 
we continue to believe that 1 business day is the appropriate timeframe 
for the reasons discussed in the 2024 CMS Interoperability and Prior 
Authorization final rule (89 FR 8775-8776). Similarly, that 1 business 
day timeframe aligns with the existing requirements to make claims and 
encounter data and all data classes and data elements included in a 
content standard in 45 CFR 170.213 (USCDI) available via the Access 
APIs no later than 1 business day after being processed or received by 
the payer.
    Additionally, we propose that information about prior 
authorizations for drugs be required to be available via the Access 
APIs for as long as the authorization is active and at least 1 year 
after the last status change. Information about denied and expired 
prior authorizations for drugs would therefore be available for at 
least 1 year after expiring or being denied. Consistent with the 
requirements to make available information about prior authorizations 
for non-drug items and services, we are not proposing to require payers 
to share a patient's full prior authorization history because that 
could comprise a significant amount of information that may no longer 
be clinically relevant. Furthermore, as payers' prior authorization 
policies may change over time, that information has a limited lifespan 
of usefulness for a patient's current care. However, our proposal would 
require payers to make available information about all active 
authorizations for as long as they are active, which may indicate a 
relationship to ongoing care.
    In summary, we request comment on our proposals in the CFR 
citations listed in Table 10, and specifically on the following:
     The proposal to require impacted payers to add information 
about prior authorization requests and decisions for all drugs to the 
categories of data they are required to make available through the 
Access APIs, within the timeframes established for non-drug items and 
services.
     The proposed October 1, 2027 compliance dates for MA 
organizations, state Medicaid and CHIP FFS programs, Medicaid managed 
care plans, CHIP managed care entities, and QHP issuers on the FFEs.
2. Reporting Usage Metrics for Patient Access, Provider Access, Payer-
to-Payer, and Prior Authorization APIs
a. Background
    Beginning in 2026, impacted payers are required to annually report 
to CMS certain metrics about patient data requests made via the Patient 
Access API. Impacted payers must annually report Patient Access API 
metrics to CMS in the form of aggregated, de-identified data following 
any year that the payer was subject to the requirement to make the 
Patient Access API available. Specifically, by March 31, 2026, MA 
organizations at the contract level, state Medicaid and CHIP FFS 
programs at the state level, and Medicaid managed care plans and CHIP 
managed care entities at the plan level must report the following 
metrics: (1) the total number of unique patients whose data are 
transferred via the

[[Page 19971]]

Patient Access API to a health app designated by the patient; and (2) 
the total number of unique patients whose data are transferred more 
than once via the Patient Access API to a health app designated by the 
patient.\239\ The current regulation in 45 CFR 156.221(f) provides that 
individual market QHP issuers on the FFEs at the issuer level also 
report these data by March 31, 2026, but CMS has specified to plans in 
sub-regulatory guidance that we will collect Patient Access API usage 
metrics during the QHP certification process.\240\
---------------------------------------------------------------------------

    \239\ See 42 CFR 422.119(f) for MA organizations, 42 CFR 
431.60(f) for state Medicaid FFS programs, 42 CFR 457.730(f) for 
state CHIP FFS programs, through cross reference to 42 CFR 431.60 in 
42 CFR 438.242(b)(5)(iii) for Medicaid managed care plans, through 
cross reference to 42 CFR 438.242 in 42 CFR 457.1233(d) for CHIP 
managed care entities.

Information and Insurance Oversight. (2026, February 25). FFEs 2027 
Draft Letter to Issuers in the Federally-facilitated Exchanges. 
Retrieved from https://www.cms.gov/files/document/draft-2027-letter-issuers.pdf.
---------------------------------------------------------------------------

    These data will help CMS better understand whether the Patient 
Access API requirement is effectively and efficiently providing 
patients access to their health information and whether payers are 
providing that required information in a transparent and timely way. 
Additionally, aggregated usage data from each impacted payer will help 
us evaluate whether the Patient Access API policies are achieving the 
desired goals. By gathering that information, we can provide targeted 
support or guidance to impacted payers, if needed, to ensure that 
patients have access to their data and can use their data consistently 
across impacted payers. Multiple data transfers indicate repeat access, 
showing that patients are either using multiple apps or allowing apps 
to update their information over the course of the year. While data 
transfers may not indicate to what extent patients are using apps to 
manage their health care, it would be a preliminary indicator of 
interest in the technology (89 FR 8779).
    The current regulation requires that impacted payers report metrics 
from the previous calendar year to CMS by March 31 of each year.\241\ 
In the first year of the requirement, impacted payers will report 
calendar year 2025 data by March 31, 2026. A MA organization, Medicaid 
managed care plan, CHIP managed care entity, or individual market QHP 
issuer on the FFEs that is newly offering coverage in a particular 
market would naturally have no data to report in its first year of 
operation and is required to report data following its first year 
subject to the Patient Access API requirement (89 FR 8780). We did not 
propose, and thus did not finalize, policies for impacted payers to 
report usage metrics to CMS about Provider Access, Payer-to-Payer, or 
Prior Authorization APIs.

431.60(f) for state Medicaid FFS programs, 42 CFR 457.730(f) for 
state CHIP FFS programs, through cross reference to 42 CFR 431.60 in 
42 CFR 438.242(b)(5)(iii) for Medicaid managed care plans, through 
cross reference to 42 CFR 438.242 in 42 CFR 457.1233(d) for CHIP 
managed care entities, and 45 CFR 156.221(f) for individual market 
QHP issuers on the FFEs.
---------------------------------------------------------------------------

b. Proposed Changes to Patient Access API Usage Metrics for Medicaid 
Managed Care Plans, CHIP Managed Care Entities, and Individual Market 
QHP Issuers on the FFEs
    After finalizing the Patient Access API usage metrics in the 2024 
CMS Interoperability and Prior Authorization final rule, we determined 
that additional proposals would be appropriate for Medicaid managed 
care plans, CHIP managed care entities, and individual market QHP 
issuers on the FFEs to align reporting deadlines for API usage metrics 
with other reporting deadlines. Similar proposals for small group 
market QHP issuers on the FF-SHOPs, with a later applicability date, 
are discussed in section II.D. of this proposed rule.
    Specifically, Medicaid managed care plans' and CHIP managed care 
entities' program contracts do not all use the same time period, and 
each state may choose different contract rating periods for each 
managed care program. Medicaid managed care plans' and CHIP managed 
care entities' contracts may use any 12-month period and collecting 
Patient Access API usage data based on a calendar year would thus be 
out of alignment with other reporting obligations in the contracts. 
Because rating periods do not necessarily align with calendar years, we 
now believe that the March 31 reporting deadline finalized in the 2024 
CMS Interoperability and Prior Authorization final rule may not be 
appropriate for all Medicaid managed care plans and CHIP managed care 
entities. Therefore, to align the reporting deadlines with the contract 
rating period and its requirements, we are now proposing to require 
Medicaid managed care plans and CHIP managed care entities to report 
Patient Access API usage metrics from each rating period to the state 
no later than 90 days after the end of each rating period. For Medicaid 
managed care plans, these metrics will be reported to CMS by states in 
their MCPARs, which are due 180 days after the end of the rating 
period. Having Medicaid managed care plans report Patient Access API 
usage metrics to the state no later than 90 days after the end of each 
rating period provides states with ample time to collect and process 
the data for inclusion in their MCPARs. To simplify the cross-
referencing regulatory text, we also propose, in 42 CFR 
438.242(b)(5)(ii)(B), to be explicit that the requirement for Medicaid 
managed care plans and CHIP managed care entities is to report API 
usage metrics to the state, rather than to CMS directly.
    Furthermore, we propose to amend the requirements for Medicaid 
managed care plans and CHIP managed care entities to clarify that they 
would be required to report the Patient Access API usage metrics by 
program, as well as by plan. We plan to collect metrics from Medicaid 
managed care plans via the states through the MCPAR system, which is 
set up to receive reports from plans by program.\242\ For consistency 
with the other Medicaid and CHIP managed care reporting requirements, 
we believe that it is appropriate to also collect these metrics at the 
program level. Specifically, this proposal means that if a specific 
managed care plan contracts with the state for multiple programs (for 
example, an adult and child acute care program and an LTSS program), 
each program would separately report Patient Access API usage metrics. 
This is also consistent with how states must report all data in the 
MCPAR, as described in 42 CFR 438.66(e). For CHIP managed care 
entities, we are currently working to finalize the mechanism for states 
to submit Patient Access API usage metrics to CMS. We plan to provide 
future guidance for states on CHIP managed care entities reporting 
requirements and processes.

Technical Assistance Resource for States. Retrieved from https://www.medicaid.gov/sites/default/files/2024-04/mcpar-faq-march-2024v.2.pdf.
---------------------------------------------------------------------------

    The certification process for new and existing QHP issuers on the 
FFEs for the next plan year begins in the prior calendar year. QHP 
issuers on the FFEs are required to submit to CMS their initial 
application for plan certification for each plan year in June of the 
previous calendar year. Because the current annual March 31 reporting 
deadline finalized in 45 CFR 156.221(f) in the 2024 CMS 
Interoperability and Prior Authorization final rule falls before the 
annual QHP certification application deadline, we believe it would be 
more appropriate to align the deadlines so that QHP issuers on the FFEs 
can submit Patient Access API usage metrics as part of the annual QHP 
certification process. Further, other

[[Page 19972]]

reporting requirements in 45 CFR part 156, subpart C do not generally 
include specific dates by which issuers must report the required 
information but rely on the annual application deadline.\243\ 
Therefore, we propose regulatory text to refer to the reporting 
deadline for Patient Access API usage metrics in a manner similar to 
the reporting deadlines for other plan data that CMS collects during 
the annual QHP certification process. Specifically, we propose that 
following each year it offers a QHP on a FFE, a QHP issuer on the FFEs 
must report the specified metrics to CMS as aggregated, de-identified 
data at the issuer level in the form and manner and within the 
timeframes specified by the Secretary. That would allow flexibility for 
CMS to include API usage metrics reporting within specific deadlines 
set for the QHP certification process, which in practice, is generally 
the final deadline for the QHP certification process that takes place 
the following year.\244\ For example, QHP issuers on the FFEs would be 
required to submit metrics from plan years in 2026 as part of the QHP 
certification process during 2027 for plan years in 2028. In practice, 
CMS has already issued sub-regulatory guidance that CMS will collect 
Patient Access API usage metrics during the QHP certification 
process.\245\ Amending the regulatory text to align with how 45 CFR 
part 156, subpart C frames other QHP certification-related deadlines 
would streamline reporting by allowing issuers to report metrics at the 
same time and to the same systems as the QHP certification application. 
We are proposing that these changes become effective beginning on the 
effective date of the final rule.
---------------------------------------------------------------------------

    \243\ For example, 45 CFR 156.220(b) provides that a QHP issuer 
on the FFEs must submit transparency in coverage metrics described 
in paragraph (a) of that section in an accurate and timely manner, 
to be determined by HHS.

    In summary, we request comment on our proposals in the CFR 
citations listed in Table 10, and specifically on the following:
     The proposal for Medicaid managed care plans and CHIP 
managed care entities to report Patient Access API usage metrics to the 
state no later than 90 days after the end of each rating period.
     The proposal for QHP issuers on the FFEs to report Patient 
Access API usage metrics to CMS in the form and manner and within the 
timeframes specified by the Secretary.
     The proposal to require Medicaid managed care plans and 
CHIP managed care entities to report certain metrics about Patient 
Access API usage, as finalized in the 2024 CMS Interoperability and 
Prior Authorization final rule, by program, as well as by plan.
     The proposal to become effective beginning on the 
effective date of the final rule.
c. Proposal to Report Metrics About the Provider Access, Payer-to-
Payer, and Prior Authorization API Usage for All Impacted Payers
    We are proposing that impacted payers be required to report metrics 
about usage of the Provider Access, Payer-to-Payer, and Prior 
Authorization APIs, which are required under the 2024 CMS 
Interoperability and Prior Authorization final rule. We propose that, 
beginning in 2028, MA organizations, state Medicaid and CHIP FFS 
programs, Medicaid managed care plans, CHIP managed care entities, and 
QHP issuers on the FFEs would be required to annually report metrics in 
the form of aggregated, de-identified data.
    The reporting period for MA organizations, state Medicaid and CHIP 
FFS programs, and QHP issuers on the FFEs would be the calendar year, 
while the reporting period for Medicaid managed care plans and CHIP 
managed care entities would be the rating period. We propose that, 
beginning in 2028, MA organizations and state Medicaid and CHIP FFS 
programs be required to report the previous calendar year's metrics to 
CMS by March 31 of each year. We propose that by the first rating 
period beginning on or after January 1, 2028, Medicaid managed care 
plans and CHIP managed care entities be required to report metrics to 
states from each rating period no later than 90 days after the end of 
each rating period. We propose that for plan years beginning on or 
after January 1, 2028, following each year it offers a QHP on a FFE, 
unless granted an exception for the previous year, a QHP issuer on the 
FFEs must report usage metrics to CMS in the form and manner and within 
the timeframes specified by the Secretary. Impacted payers would thus 
be required to begin reporting these data in 2028 for the previous 
reporting period (for most impacted payers, calendar year 2027). As 
discussed in section II.C.6. of this proposed rule, we use the term 
``reporting period'' to describe the period from which data must be 
reported in order to account for certain differences between impacted 
payers.
    We also propose that MA organizations, state Medicaid and CHIP FFS 
programs, and QHP issuers on the FFEs would report the metrics at the 
same reporting levels, that is, the organizational levels at which the 
payer aggregates and submits the required data, as finalized for the 
Patient Access API usage metrics. MA organizations would thus report at 
the contract level, state Medicaid and CHIP FFS programs at the state 
level, and QHP issuers on the FFEs at the issuer level. We also propose 
that Medicaid managed care plans and CHIP managed care entities would 
report metrics at the plan and program level for the reasons discussed 
previously. By way of examples, reporting at the issuer level means 
that a QHP issuer on the FFEs would aggregate data across the plans it 
offers on a FFE, while reporting at the plan level means that a 
Medicaid managed care plan would report data specific to that 
individual plan. As we finalized for the Patient Access API (89 FR 
8780), dual eligible special needs plans (D-SNPs) would report 
consistent with MA organizations at the contract level, and with 
Medicaid managed care plans at the plan level. Therefore, the MA 
organization would report information about Provider Access, Payer-to-
Payer, and Prior Authorization API usage by its D-SNP enrollees to CMS 
at the contract level. The affiliated Medicaid managed care plan would 
report on information about Patient Access API usage by its enrollees 
to CMS at the plan and program level.
    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we explained that we believe that it is most appropriate for MA 
organizations to report these usage data at the contract level (89 FR 
8780). Contract level data represent aggregated information from all 
PBPs that fall under a single MA contract, with reporting organized by 
individual contracts rather than by individual plans. We already 
require MA organizations to annually report contract level data about 
their organization's determinations to CMS. Maintaining consistent 
contract level reporting in the MA program would give us useful 
information while limiting payer burden. By requiring contract level 
reporting for these metrics, the format of these reported data would 
remain consistent with other data that MA organizations are required to 
report. There could be value in requiring MA organizations to report on 
a plan level in the future to get more discrete data.

[[Page 19973]]

However, at this time, we continue to believe that the burden of 
requiring MA organizations to report at the plan level, especially 
given the small sample sizes of some plans, outweighs the benefits of 
obtaining that information.
    Commenters agreed with our proposals in the 2022 CMS 
Interoperability and Prior Authorization proposed rule that requiring 
state Medicaid and CHIP FFS programs to report at the state level, 
Medicaid managed care plans and CHIP managed care entities to report at 
the plan level, and individual market QHP issuers on the FFEs to report 
at the issuer level balances the reporting burden and the 
meaningfulness of the data (89 FR 8780). We explained in the 2024 CMS 
Interoperability and Prior Authorization final rule that requiring 
individual market QHP issuers on the FFEs to report at the issuer 
level, thereby aggregating plans under their purview, is consistent 
with their reporting on quality improvement strategies, as described in 
section 1311(g) of the Affordable Care Act and codified in 45 CFR 
156.1130(a), which provides consistency with other QHP reporting 
requirements (89 FR 8890). Likewise, for these proposals, state 
Medicaid and CHIP FFS programs would report at the state level, 
Medicaid managed care plans and CHIP managed care entities at the plan 
and program level, and QHP issuers on the FFEs at the issuer level. Our 
proposed reporting levels and deadlines are summarized in Table 9.
    As with the existing Patient Access API metrics (89 FR 8781), if we 
finalize this proposal, we do not plan to publicly report these metrics 
at the contract, state, plan and program, or issuer level, but may 
reference or publish aggregated and de-identified data that does not 
include names of specific payers or plans.
    We are also not proposing a specific form or manner of reporting 
these metrics at this time but would issue specific format and process 
guidance for submitting these metrics, should they be finalized.
    We propose that, beginning in 2028, impacted payers be required to 
annually report Provider Access API usage metrics in the form of 
aggregated, de-identified data. MA organizations, state Medicaid and 
CHIP FFS programs, and QHP issuers on the FFEs would be required to 
report these metrics directly to CMS and Medicaid managed care plans 
and CHIP managed care entities would be required to report these 
metrics to states.
    Specifically, impacted payers would be required to report the 
following metrics about their Provider Access API:
     The total number of unique providers who requested patient 
data via their Provider Access API.
     The total number of unique patients whose data were 
transferred via their Provider Access API to a provider's health IT 
system (for example, an EHR or health IT system).
     The total number of patient data transfers via their 
Provider Access API.
    In response to the 2022 CMS Interoperability and Prior 
Authorization proposed rule, some commenters expressed skepticism that 
providers would use the Provider Access API (89 FR 8792 through 8794). 
We are proposing these metrics because we believe that they would give 
us valuable insight into how frequently the Provider Access API is 
being used. In addition, we believe that obtaining these metrics would 
be manageable for impacted payers and thus not present a substantial 
burden.
    For the purposes of this proposal, payers must count each provider 
who queries the Provider Access API. As we established in the 2024 CMS 
Interoperability and Prior Authorization final rule, the Provider 
Access API should be available to all providers, whether they are an 
individual, a facility, or a group of providers who have come together 
as an accountable care organization (ACO), who are appropriately 
licensed, provide items and services, or drugs eligible for coverage by 
the payer, and are enrolled with the payer or in the payer's provider 
network. Though we do not require payers to share patient data with 
out-of-network or unenrolled providers, we encourage them to do so to 
the extent permitted by law if they can verify a treatment relationship 
(89 FR 8790 and 8791). This proposed approach ensures payers would 
comprehensively report all usage of the Provider Access API, including 
out-of-network and unenrolled providers where applicable. We believe 
that impacted payers would be able to obtain these metrics based on 
their records of which providers have been authenticated and authorized 
to receive requested patient data. We also recognize, however, that 
there may be other ways for these payers to obtain these metrics, as 
well as other outstanding factors that they would need to address to 
obtain the metrics that we may not be considering.
    We propose that, beginning in 2028, impacted payers be required to 
annually report Payer-to-Payer API usage metrics in the form of 
aggregated, de-identified data. MA organizations, state Medicaid and 
CHIP FFS programs, and QHP issuers on the FFEs would be required to 
report these metrics directly to CMS and Medicaid managed care plans 
and CHIP managed care entities would be required to report these 
metrics to states.
    Specifically, impacted payers would be required to report all of 
the following metrics about their Payer-to-Payer API:
     The percent of patients who have opted in to the payer to 
payer data exchange.
     The total number of unique patients whose data have been 
sent to other payers.
     The total number of unique patients whose data have been 
received from other payers.
    We believe that by monitoring the patient opt in rate, we could 
better understand patient receptiveness to payer to payer data 
exchange, as well as how impacted payers are implementing it. For 
example, this information may identify potential barriers to patient 
opt in, such as unclear patient educational resources.
    We propose that, beginning in 2028, impacted payers would be 
required to annually report Prior Authorization API usage metrics in 
the form of aggregated, de-identified data. MA organizations, state 
Medicaid and CHIP FFS programs, and QHP issuers on the FFEs would be 
required to report these metrics directly to CMS and Medicaid managed 
care plans and CHIP managed care entities would be required to report 
these metrics to states.
    Specifically, impacted payers would be required to report all of 
the following metrics about their Prior Authorization API:
     The total number of unique providers who request a prior 
authorization for items, services, or drugs through their Prior 
Authorization API.
     The number of unique prior authorization requests for 
items, services, and drugs received through their Prior Authorization 
API.
     The percentage of all prior authorization requests that 
were received through their Prior Authorization API.
    We finalized a requirement in the 2024 CMS Interoperability and 
Prior Authorization final rule that impacted payers implement and 
maintain a Prior Authorization API to facilitate electronic prior 
authorization for providers to send prior authorization requests and 
receive decisions from payers.\246\ While we strongly encourage

[[Page 19974]]

providers to use the Prior Authorization API, specific requirements 
regarding provider adoption are implemented by other programs, such as 
the Electronic Prior Authorization measures in the MIPS Promoting 
Interoperability performance category and the Medicare Promoting 
Interoperability Program. We believe that these additional data 
regarding provider usage would complement the data we would eventually 
receive from MIPS eligible clinicians, eligible hospitals, and CAHs 
reporting the Electronic Prior Authorization measures under those 
programs (89 FR 8909 through 8927). Understanding how many providers 
are adopting the processes to send and receive electronic prior 
authorizations through the API would give CMS information to shape 
future interoperability and prior authorization policies.

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

    In summary, we request comment on our proposals in the CFR 
citations listed in Table 10, and specifically on the following:
     The proposal to require impacted payers to report metrics 
about the usage of the Provider Access, Payer-to-Payer, and Prior 
Authorization APIs in the form of aggregated, de-identified data.
     The proposal to require MA organizations to report at the 
contract level, state Medicaid and CHIP FFS programs to report at the 
state level, Medicaid managed care plans and CHIP managed care entities 
to report at the plan and program level, and QHP issuers on the FFEs at 
the issuer level.
     The proposed compliance dates beginning in 2028 to report 
metrics from the 2027 reporting period, and the proposed reporting 
deadlines thereafter (summarized in Table 9).
    In addition, we request comments on the following:
     CMS's position that it does not plan to publicly report 
these metrics at the contract, state, plan and program, or issuer 
level, but may reference or publish aggregated and de-identified data 
that does not include names of specific payers or plans.
     With respect to the proposed Provider Access API usage 
metrics, the feasibility of separately reporting the total number of 
individual providers and groups of providers who request patient data 
via the Provider Access API, and whether we should finalize 
requirements for these payers to report separate metrics for 
individuals and groups of providers.
     With respect to the proposed Payer-to-Payer API usage 
metrics, whether we should disaggregate these metrics by data exchanges 
between an old and new payer and those between concurrent payers.
     Whether there are different metrics that we should 
consider requiring impacted payers to report.
     With respect to states reporting usage metrics to CMS via 
the APD process described in 45 CFR part 95, subpart F, whether there 
are existing or alternative reporting mechanisms for Medicaid and CHIP 
data for states to leverage to better facilitate the reporting process. 
Specifically, whether the use of an online portal or form would be 
simpler to meet the annual deadlines or whether a FHIR[supreg] server 
to automate reporting would be preferred, and what the anticipated 
level of burden would be.

3. Removing Drug Formulary Information From the Provider Access and 
Payer-to-Payer APIs
a. Background
    In the 2020 CMS Interoperability and Patient Access and 2024 CMS 
Interoperability and Prior Authorization final rules, we required that 
certain impacted payers make available information about their drug 
formularies through the Access APIs. MA-PDs must make available drug 
formulary information, including covered Part D drugs and any tiered 
formulary structure or utilization management procedure which pertains 
to those drugs. State Medicaid and CHIP FFS programs, Medicaid managed 
care plans, and CHIP managed care entities must make available 
information about covered outpatient drugs, including, where 
applicable, preferred drug list information.\247\ We did not require 
QHP issuers on the FFEs to make drug formulary data available, as they 
are already required to provide these data in

[[Page 19975]]

a machine-readable format to CMS and post it on their websites.\248\
---------------------------------------------------------------------------

    \247\ The applicable regulations used a cross reference to the 
regulatory provision for the scope of information available through 
the Patient Access API to accomplish this. For example, the 
regulation in 42 CFR 422.121(a)(2) requires MA organizations to 
include in their Provider Access APIs information that is listed in 
42 CFR 422.119(b), a provision from the regulation that requires MA 
organizations to make certain information available through the 
Patient Access API. For MA organizations, the obligation to include 
drug formulary information is limited to MA-PD plans and their 
covered Part D drug formularies. See through cross reference to 42 
CFR 422.119(b) in 42 CFR 422.121(a)(2) (Provider Access API) and in 
42 CFR 422.121(b)(4)(ii)(A) (Payer-to-Payer API) for MA 
organizations, through cross reference to 42 CFR 431.60(b) in 42 CFR 
431.61(a)(2) (Provider Access API) and in 42 CFR 431.61(b)(4)(ii)(A) 
(Payer-to-Payer API) for state Medicaid FFS programs, through cross 
reference to 42 CFR 457.730(b) in 42 CFR 457.731(a)(2) (Provider 
Access API) and in 42 CFR 457.731(b)(4)(ii)(A) (Payer-to-Payer API) 
for state CHIP FFS programs, through cross reference to 42 CFR 
431.61 in 42 CFR 438.242(b)(7) (Provider Access and Payer-to-Payer 
APIs), and through cross reference to 42 CFR 438.242 in 42 CFR 
457.1233(d) (Provider Access and Payer-to-Payer APIs).

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

b. Proposals
    Upon further examination of this finalized policy, we determined 
that the inclusion of drug formulary data in the Provider Access API 
and Payer-to-Payer API may be unnecessary and burdensome. We believe 
that providers already have sufficient access to drug formulary 
information through other means, such as payer websites and standard 
payer communications materials, and both impacted payers and patients 
would have little use for this information if they received it from a 
previous or concurrent payer. We thus believe that the benefit of 
including drug formulary data in these APIs does not outweigh the 
additional effort it would take impacted payers to make them available. 
Therefore, we propose to remove drug formulary information as data 
required to make available via the Provider Access and Payer-to-Payer 
APIs for MA organizations, state Medicaid and CHIP FFS programs, 
Medicaid managed care plans, and CHIP managed care entities. If 
finalized, we propose that this would be effective beginning on the 
effective date of the final rule. While we propose removing these data 
from our requirements, we remind impacted payers that they would not be 
prohibited from continuing to include them should they see value in 
doing so. We emphasize that we are not proposing to change the current 
requirement for MA organization, state Medicaid and CHIP FFS programs, 
Medicaid managed care plans, and CHIP managed care entities to make the 
required formulary information available via the Patient Access API.
    In summary, we request comment on our proposals in the CFR 
citations listed in Table 10, and specifically on the following:
     The proposal to remove drug formulary information as data 
required to be made available via the Provider Access and Payer-to-
Payer APIs for MA organizations, state Medicaid and CHIP FFS programs, 
Medicaid managed care plans, and CHIP managed care entities.
     The proposal to become effective beginning on the 
effective date of the final rule.
    In addition, we request comments on the following:
     Whether there are use cases where it would be helpful for 
any party to have access to drug formulary data via those APIs.
4. Denial or Discontinuation of Access to the Provider Directory API
a. Background
    In the 2020 CMS Interoperability and Patient Access final rule and 
2024 CMS Interoperability and Prior Authorization final rule, we 
finalized requirements that impacted payers must implement and maintain 
Patient Access, Provider Access, Payer-to-Payer, and Prior 
Authorization APIs conformant with certain technical standards, 
documentation requirements, and denial or discontinuation policies (85 
FR 25524 through 25559, 89 FR 8817, 8855, and 8897). We believe that 
consistently applying these requirements to all of the APIs would 
minimize the cost and burden of implementation and support payer risk 
mitigation strategies. However, we do not currently require the 
Provider Directory API, also finalized in the 2020 CMS Interoperability 
and Patient Access final rule, to be conformant with the denial or 
discontinuation policies for the other APIs.\249\ Specifically, those 
impacted payers may only deny or discontinue any third-party app's 
connection to the API if they (1) reasonably determine, consistent with 
their security risk analysis required by the HIPAA Security Rule, that 
allowing an app to connect or remain connected to the API would present 
an unacceptable level of risk to the security of PHI on their systems; 
and (2) make this determination using objective, verifiable criteria 
that are applied fairly and consistently across all apps and developers 
through which parties seek to access electronic health information 
(EHI), as defined in 45 CFR 171.102, including but not limited to, 
criteria that rely on automated monitoring and risk mitigation 
tools.\250\ Because QHP issuers on the FFEs were already required to 
make provider directory information available in a specified, machine-
readable format,\251\ we did not require them to make provider 
directory information available through an API.

cross reference to 42 CFR 438.242 in 42 CFR 457.1233(d) for CHIP 
managed care entities.
    \251\ See 45 CFR 156.230(c).
---------------------------------------------------------------------------

b. Proposals
    To align requirements across all APIs, we are now proposing that MA 
organizations, state Medicaid and CHIP FFS programs, Medicaid managed 
care plans, and CHIP managed care entities update their Provider 
Directory API policies to conform with the denial or discontinuation 
policies that apply to the other APIs. We are proposing that impacted 
payers would be required to implement that policy by the effective date 
of the final rule. We believe that those impacted payers should not 
have difficulty implementing this policy change, as it would not 
require developing or modifying any technology but rather applying the 
same denial and discontinuation policy that exists for other APIs to 
the Provider Directory API. However, we encourage the impacted payers 
to whom this proposal applies to update their denial and 
discontinuation policy for the Provider Directory APIs as soon as 
possible.
    In summary, we request comment on our proposals in the CFR 
citations listed in Table 10, and specifically on the following:
     The proposal to require MA organizations, state Medicaid 
and CHIP FFS programs, Medicaid managed care plans, and CHIP managed 
care entities to update their Provider Directory APIs denial or 
discontinuation policies.
     The proposal to become effective beginning on the 
effective date of the final rule.
5. Other Amendments to Access API Requirements
a. Applicability Dates
    In the 2020 CMS Interoperability and Patient Access final rule, we 
finalized requirements that impacted payers must implement and maintain 
a Patient Access API beginning in 2021 (by January 1, 2021 for MA 
organizations and state Medicaid and CHIP FFS programs; by the rating 
period beginning on or after January 1, 2027 for Medicaid managed care 
plans and CHIP managed care entities; and for plan years beginning on 
or after January 1, 2027 for individual market QHP issuers on the 
FFEs). We also finalized a requirement that impacted payers make 
available through the Patient Access API the specified data they 
maintain with a date of service on or after January 1, 2016 (85 FR 
25558 through 25560). We finalized those requirements in an 
applicability paragraph in 42 CFR 422.119 for MA organizations, 42 CFR 
431.60 for state Medicaid FFS programs, 42 CFR 457.730 for state CHIP 
FFS programs, through cross reference to 42 CFR 431.60 in 42 CFR 
438.242(b)(5) for

[[Page 19976]]

Medicaid managed care plans, through cross reference to 42 CFR 438.242 
in 42 CFR 457.1233(d) for CHIP managed care entities, and 45 CFR 
156.221 for individual market QHP issuers on the FFEs.
    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we finalized requirements that impacted payers must implement and 
maintain Provider Access, Payer-to-Payer, and Prior Authorization APIs 
with compliance dates in 2027 (by January 1, 2027 for MA organizations 
and state Medicaid and CHIP FFS programs; by the rating period 
beginning on or after January 1, 2027 for Medicaid managed care plans 
and CHIP managed care entities; and for plan years beginning on or 
after January 1, 2027 for individual market QHP issuers on the FFEs) 
(89 FR 8817, 8855, and 8897). We also finalized requirements that 
impacted payers make available through the Provider Access API 
specified data they maintain with a date of service on or after January 
1, 2016 and, through the Payer-to-Payer API, to exchange data they 
maintain with a date of service within 5 years of the request (89 FR 
8799 and 8855).
    To simplify the regulatory text, we propose to incorporate the 2021 
applicability date into the paragraph that includes the Patient Access 
API requirements in 42 CFR 422.119(a) for MA organizations, 42 CFR 
431.60(a) for state Medicaid FFS programs, 42 CFR 457.730(a) for state 
CHIP FFS programs, and 45 CFR 156.221(a) for QHP issuers on the FFEs. 
We further propose to incorporate the requirement for impacted payers 
to make available data with a date on or after January 1, 2016 in 42 
CFR 422.119(b)(1) for MA organizations, 42 CFR 431.60(b) for state 
Medicaid FFS programs, 42 CFR 457.730(b) for state CHIP FFS programs, 
and 45 CFR 156.221(b)(1) for individual market QHP issuers on the FFEs. 
These proposals would not change any existing requirements or impose 
any new requirements.
    Because the requirements for the Provider Access and Payer-to-Payer 
APIs cross reference to the accessible content available through the 
Patient Access API, we believe that this would simplify and explain the 
regulatory requirements for all three of these APIs. This proposal 
would become effective beginning on the effective date of the final 
rule.
    In summary, we request comment on our proposals in the CFR 
citations listed in Table 10, and specifically on the following:
     The proposal to incorporate the existing Patient Access 
API 2021 implementation date into 42 CFR 422.119(a), 42 CFR 431.60(a), 
42 CFR 457.730(a), and 45 CFR 156.221(a).
     The proposal to incorporate the existing requirement for 
impacted payers to make available data with a date on or after January 
1, 2016 into 42 CFR 422.119(b)(1), 42 CFR 431.60(b), 42 CFR 457.730(b), 
and 45 CFR 156.221(b)(1).
     The proposal to become effective beginning on the 
effective date of the final rule.
b. Exceptions for QHP Issuers on the FFEs
    In the preambles to the 2022 CMS Interoperability and Prior 
Authorization proposed rule and 2024 CMS Interoperability and Prior 
Authorization final rule, we discussed that issuers seeking to offer 
QHPs on the FFEs that submit an exception request would have to 
describe the effect of non-compliance upon enrollees, providers, and 
payers and the current or proposed means of providing the required 
information to providers or other payers, as applicable to each API (87 
FR 76263, 87 FR 76281, and 89 FR 8905). However, the regulatory text in 
45 CFR 156.222(c)(1)(iii) only requires QHP issuers on the FFEs that 
are applying for an exception to describe the impact of non-compliance 
on providers and enrollees and the current or proposed means of 
providing health information to payers.
    Therefore, we propose to amend 45 CFR 156.222(c)(1)(ii) and 45 CFR 
156.222(c)(1)(iii) to incorporate the requirement to describe the 
impact on all applicable parties. Specifically, we propose to amend 45 
CFR 156.222(c)(1)(ii) to require QHP issuers on the FFEs applying for 
an exception describe the impact of non-compliance upon enrollees and 
providers, if the exception request is for the Provider Access API, or 
upon enrollees and payers, if the exception request is for the Payer-
to-Payer API. In addition, we propose to amend 45 CFR 
156.222(c)(1)(iii) to refer to the current or proposed means of 
providing health information to providers if the exception is for the 
Provider Access API, or to other payers if the exception request is for 
the Payer-to-Payer API. Similarly, we propose to amend 45 CFR 
156.223(i)(1)(iii) to require QHP issuers on the FFEs that apply for an 
exception to describe the current or proposed means of providing prior 
authorization coverage and documentation requirements and facilitating 
prior authorization requests and decisions.
    In summary, we request comment on our proposals in the CFR 
citations listed in Table 10, and specifically on the following:
     The proposal to amend language in 45 CFR 156.222(c)(1)(ii) 
and 45 CFR 156.222(c)(1)(iii), and 45 CFR 156.223(i)(1)(iii) to require 
QHP issuers on the FFEs applying for an exception to describe the 
impact of non-compliance on all applicable parties.
6. Federal Matching Funds
    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we stated that we expected that states operating state Medicaid 
and CHIP FFS programs would be able to access federal matching funds to 
support their implementation of the required APIs (89 FR 8907). We 
explained that all of the required APIs would support the efficient 
data exchange and prior authorization processes, consistent with 
sections 1902(a)(4) and 2101(a) of the Act. Similarly, FFP could be 
available for state expenditures to meet the proposals in this proposed 
rule at a rate of 50 percent under section 1903(a)(7) of the Act for 
the proper and efficient administration of the Medicaid state plan.
    Furthermore, as with requirements in the 2024 CMS Interoperability 
and Prior Authorization final rule (89 FR 8907), state expenditures to 
implement certain proposals in this proposed rule could be eligible for 
90 percent enhanced FFP under section 1903(a)(3)(A)(i) of the Act if 
the expenditures can be attributed to the design, development, and 
installation of mechanized claims processing and information retrieval 
systems. Additionally, 75 percent enhanced FFP, under section 
1903(a)(3)(B) of the Act, could be available for state expenditures to 
operate Medicaid mechanized claims processing and information retrieval 
systems. States can request Medicaid enhanced FFP under section 
1903(a)(3)(A)(i) or (B) of the Act through the APD process described in 
45 CFR part 95, subpart F. Additionally, 42 CFR 433.112(b)(12) and 42 
CFR 433.116(c) require that any system for which states are receiving 
enhanced FFP under section 1903(a)(3)(A)(i) or (B) of the Act align 
with and incorporate the ONC Health IT standards adopted in 45 CFR part 
170, subpart B. The proposals that would require API implementation or 
enhancement in this proposed rule complement this requirement to 
support interoperability by using standards adopted by ONC.
    Separately, for CHIP agencies, section 2105(c)(2)(A) of the Act and 
42 CFR 457.618 limiting administrative costs to no more than 10 percent 
of a state's total computable expenditures for a FY

[[Page 19977]]

would apply to administrative claims for complying with the proposals 
in this proposed rule, if finalized.

7. Statutory Authorities
a. Medicare Advantage Organizations
    For MA organizations, we are proposing the new requirement to add 
information about prior authorizations for drugs to the Access APIs 
under our authority at the following sections of the Act:
     Section 1856(b)(1) of the Act, which requires the 
Secretary to promulgate regulations implementing MA standards, 
including the requirements in section 1852(h) of the Act for MA 
organizations that maintain medical records or other health information 
about enrollees to maintain such records in a manner that is accurate 
and timely and to ensure access for enrollees to such records and 
information.
     Section 1857(e)(1) of the Act, which authorizes the 
Secretary to add contract terms determined by the Secretary to be 
necessary and appropriate and not inconsistent with the requirements in 
Part C of Title XVIII of the Act (that is, Part C of the Medicare 
statute).
     Section 1852(d)(1)(A) of the Act, which requires MA 
organizations to, as a condition of using a network of providers, make 
covered benefits available and accessible to enrollees in a manner 
which assures continuity in the provision of benefits.
(1) Patient Access API
    The Patient Access API proposal in section II.E.1.b. of this 
proposed rule that would require MA organizations to make an enrollee's 
prior authorization requests and related clinical documentation for 
drugs available through the APIs, would, if finalized as proposed, 
allow these enrollees to have access to that information in a 
convenient, timely, secure, and portable way, which is in enrollees' 
best interests. This proposed requirement is consistent with section 
1852(h) of the Act. It is essential for CMS to ensure that each MA 
organization has a standardized system in place that offers enrollees 
access to their own data, including data that pertain to their prior 
authorizations for drugs, using existing and emerging technologies of 
their choice, specifically in this case, health apps. Therefore, making 
these data available through the Patient Access API is consistent with 
our programmatic authority to establish standards to implement section 
1852(h) of the Act, and could encourage patients to be more active 
participants in their own care, which could potentially lead to better 
health outcomes.
    Making this information available via the Patient Access API could 
help enrollees support the prior authorization process, as well. 
Enrollees could see what information is needed and what information has 
been provided on their behalf to facilitate a prior authorization 
request. Enrollees, using a third-party app, could monitor the process 
and give their provider any missing information needed by the payer to 
reach a decision. This could allow MA organizations to address prior 
authorization requests more promptly, streamlining this process, and 
thus simplifying prior authorization for the MA organizations. This 
could also improve an enrollee's experience with the process, by 
facilitating timelier and potentially more successful initial prior 
authorization requests. This, again, supports efficient operation and 
timely provision of information and services.
(2) Provider Access API
    For the Provider Access API, our proposals would provide a 
mechanism for providers to access information about pending, approved, 
or denied prior authorization requests for all drugs in a timely and 
efficient manner. As noted in this section of this proposed rule, these 
regulations are consistent with and facilitate the requirements in 
section 1852(d)(1)(A) of the Act that MA organizations, as a condition 
of using a network of providers, make covered benefits available and 
accessible to enrollees in a manner which assures continuity in the 
provision of benefits. The Secretary has authority under section 
1856(b)(1) of the Act to promulgate regulations implementing MA 
standards, including the requirements in section 1852(d)(1)(A) of the 
Act. As previously stated, the Secretary also has authority under 
section 1857(e)(1) of the Act to add new contract terms, including 
additional standards and requirements, for MA organizations that the 
Secretary finds necessary and appropriate and that are not inconsistent 
with Part C of the Medicare statute.
    In implementing section 1852(d)(1)(A) of the Act, we previously 
adopted a regulation, in 42 CFR 422.112(b)(4), that requires MA 
organizations offering coordinated care plans to ensure the continuity 
of care and integration of services through arrangements with providers 
that include procedures to ensure that the MA organization and the 
contracted providers have access to the information necessary for 
effective and continuous patient care. This proposal to expand the 
scope of information available to providers through the Provider Access 
API aligns with, and provides a means for, MA organizations to comply 
with that existing regulatory requirement. Our proposal for MA 
organizations to add prior authorization information for all drugs to 
their existing Provider Access API would facilitate exchanges of 
information about enrollees that are necessary for effective and 
continuous patient care, which is consistent with the requirement in 
section 1852(d)(1)(A) of the Act for assuring continuity in the 
provision of benefits. In addition, if a patient moves from one 
provider to another, the new provider would be able to ensure 
continuity of care if they are able to access additional relevant 
health information about the patient (such as prior or existing prior 
authorization approvals and denials) from the MA organization in an 
efficient and timely way. The inclusion of prior authorization 
information for drugs in the Provider Access API could support this; 
thus, the proposal would carry out and be consistent with the Part C 
statute.
    This proposal would complement and align with MA organization 
obligations in 42 CFR 422.112(b)(4) by providing more information 
through the Provider Access API, which could further support effective 
and continuous patient care. The inclusion of drug prior authorization 
information in the API would make the Provider Access API an even more 
effective and efficient way to fulfill program requirements. Adding 
this information could increase the efficiency and simplicity of 
administration. It would give providers access to more of their 
patients' information with limited effort, and it could reduce the 
amount of time needed during provider visits to establish a patient's 
prior history, which could introduce efficiencies and improve care. 
This proposal would also allow for better access to prior authorization 
decisions for all drugs requested by other providers for the patient, 
which could give a provider a more holistic view of a patient's care 
and reduce the likelihood of ordering duplicate or misaligned services. 
Ultimately, we anticipate that sharing more patient information through 
an established Provider Access API would ensure that providers receive 
patient information in a timely manner and could lead to more 
appropriate service utilization and higher patient satisfaction. Thus, 
the proposed inclusion of drug prior authorization data in the Provider 
Access API would be necessary and appropriate for the MA program and 
consistent with existing requirements.
(3) Payer-to-Payer API
    For the Payer-to-Payer API, the exchange of drug prior 
authorization data about enrollees could further

[[Page 19980]]

facilitate continuity of care and enhance care coordination. Thus, the 
proposal for payers to share additional information could apply as well 
to data exchanges using the Payer-to-Payer API. It could give payers 
access to more of their enrollees' information with limited effort and 
enable the subsequent or other concurrent payer to then make that 
information available to providers and to enrollees through the 
Provider Access and Patient Access APIs. It could reduce the amount of 
time needed to evaluate a patient's current care plan and possible 
implications for care continuity, which could introduce efficiencies 
and improve care. If a new payer is able to receive information and 
documentation about prior authorization requests for drugs from a 
previous payer (for example, from a previous plan year), the new payer 
could review this information and determine that a new prior 
authorization review may not be necessary for a drug that was 
previously approved. Instead, the same care could be continued, 
reducing burden on both payers and providers and improving patient 
care, 42 CFR 422.112(b)(8)(i)(B) further requires coordinated care 
plans to provide a minimum 90-day transition period when an enrollee 
currently undergoing treatment switches to a new MA plan, during which 
the new MA plan may not require prior authorization for the active 
course of treatment.\252\ The proposed policy would, taken together 
with both the ``Medicare Program; Contract Year 2024 Policy and 
Technical Changes to the Medicare Advantage Program, Medicare 
Prescription Drug Benefit Program, Medicare Cost Plan Program, and 
Programs of All-Inclusive Care for the Elderly'' final rule (88 FR 
22120), which appeared in the Federal Register on April 12, 2023, and 
the 2024 CMS Interoperability and Prior Authorization final rule (89 FR 
8758), continue to support an even more streamlined process for prior 
authorization in the MA program, which would ultimately lead to reduced 
burden in health care. While the statutory provisions governing the MA 
program do not explicitly address sharing data with other payers that 
cover or have covered an enrollee, the benefits to be gained by sharing 
more data make adoption of this proposal necessary and appropriate for 
the MA program. Further, requiring the inclusion of drug prior 
authorization information in the existing Payer-to-Payer API and the 
specifications for data to be shared provides a step toward greater 
interoperability among payers. Ultimately, the inclusion of this 
information could lead to more appropriate service utilization and 
higher beneficiary satisfaction. This proposal would facilitate the 
exchange of enrollee information necessary for continuity of care, 
consistent with the requirements of section 1852(d)(1)(A) of the Act, 
which mandates that MA organizations provide enrollees with access to 
covered services in a manner that ensures continuity of care. The 
enhanced data sharing through the Payer-to-Payer API directly supports 
this statutory obligation by enabling seamless transitions between 
plans and reducing disruptions in treatment regimens. CMS is proposing 
this requirement under its authority pursuant to section 1856(b) of the 
Act to adopt standards consistent with, and to carry out, the Part C 
statute, including the continuity of care provisions in section 
1852(d)(1)(A). Additionally, CMS has authority under section 1857(e)(1) 
of the Act to establish contract terms and conditions that ensure MA 
organizations meet their obligations to enrollees. By requiring the 
inclusion of drug prior authorization information in payer to payer 
data exchanges under these statutory authorities, this proposal would 
create a more integrated health care system that prioritizes 
beneficiary needs while maintaining appropriate oversight of MA plan 
operations.
---------------------------------------------------------------------------

    \252\ See 42 CFR 422.112(b)(8)(i)(B).
---------------------------------------------------------------------------

(4) Reporting Provider Access, Payer-to-Payer, and Prior Authorization 
API Metrics
    In addition, to ensure the requirements proposed here and finalized 
in the 2024 CMS Interoperability and Prior Authorization final rule 
would be most effective, CMS proposes in this rule that MA 
organizations report specific metrics to CMS on enrollee and provider 
use of the Provider Access, Payer-to-Payer, and Prior Authorization 
APIs. Section 1857(e)(1) of the Act authorizes the Secretary to adopt 
additional MA contract terms and conditions, including required 
reporting by MA organizations, where necessary and appropriate and not 
inconsistent with Part C of the Medicare statute. Here, required 
reporting of these proposed metrics would facilitate CMS's oversight, 
evaluation, and administration of patient health data access in the 
Part C program and therefore, these data collections are necessary and 
appropriate to adopt.
    To the extent that the proposals discussed in this section apply to 
prior authorization information for Part D drugs offered by MA-PD 
plans, we are also relying on our authority under sections 1857(e)(1) 
and 1860D-12(b)(3)(D) of the Act. Section 1860D-12(b)(3)(D) of the Act 
provides that MA-PD plans are subject to the requirements of section 
1857 of the Act to the extent the Secretary determines appropriate. 
Together, these authorities support CMS's proposal to require MA-PD 
plans to make information about prior authorization requests and 
decisions for Part D drugs available through the Access APIs.
b. Medicaid
    Our proposed requirements in this section for state Medicaid FFS 
programs and Medicaid managed care plans fall generally under the 
authority in all of the following provisions of the statute:
     Section 1902(a)(4) of the Act, which requires that a state 
Medicaid plan provide such methods of administration as are found by 
the Secretary to be necessary for the proper and efficient operation of 
the state Medicaid plan.
     Section 1902(a)(8) of the Act, which requires states to 
ensure that Medicaid services are furnished with reasonable promptness 
to all eligible individuals.
     Section 1902(a)(19) of the Act, which requires states to 
ensure that care and services are provided in a manner consistent with 
simplicity of administration and the best interests of the recipients.
     Section 1932(b)(4) of the Act, which provides that each 
Medicaid MCO (and PIHP and PAHP, which this section of the Act extends 
to through regulations based on our authority under section 1902(a)(4) 
of the Act) must establish an internal grievance procedure under which 
a beneficiary who is eligible for medical assistance may challenge the 
denial of coverage or payment for such assistance.
     Section 1932(c)(1)(A) of the Act, which requires states 
that contract with Medicaid MCOs (and extended to PIHPs and PAHPs 
through regulations based on our authority under section 1902(a)(4) of 
the Act), to develop and implement a quality assessment and improvement 
strategy that includes standards for access to care so that covered 
services are available within reasonable timeframes and in a manner 
that ensures continuity of care and adequate primary care and 
specialized services capacity and procedures for monitoring and 
evaluating the quality and appropriateness of care and services to 
enrollees and requirements for provision of quality assurance data to 
the state.

[[Page 19981]]

(1) Patient Access API
    For the Patient Access API, we expect that beneficiaries would more 
easily obtain information about the status of prior authorization 
requests for drugs submitted on their behalf. Beneficiaries could 
potentially use that information to make more informed decisions about 
their health care, and, if needed and desired by the beneficiary, 
provide missing information to their provider that the state (or 
Medicaid managed care plan, if applicable) needs to reach a decision. 
Receiving missing information more quickly could enable more prompt 
responses from state Medicaid FFS programs and Medicaid managed care 
plans to drug prior authorization requests, thus facilitating more 
timely and successful prior authorizations, which would help states 
fulfill their obligations to provide care and services in a manner 
consistent with simplicity of administration and the best interests of 
the recipients, and to furnish services with reasonable promptness to 
all eligible individuals. Improving the prior authorization process 
could also improve the efficient operation of the state plan by 
potentially improving the speed and consistency of prior 
authorizations, which could, in turn, facilitate faster access to care 
for beneficiaries. In these ways, these proposals are consistent with 
section 1902(a)(4), (8), and (19) of the Act.
    In addition, the proposal for the Patient Access API would 
implement section 1932(b)(4) of the Act. CMS has traditionally extended 
requirements applicable to Medicaid MCOs via regulations to other 
Medicaid managed care plan types as efficient and proper methods of 
administration under section 1902(a)(4) of the Act to ensure that 
Medicaid beneficiaries have the same protections, benefits, and 
responsibilities regardless of the type of managed care plan in which 
they are enrolled. Allowing beneficiaries to access the status of their 
denied drug prior authorization requests within 1 business day could 
enable beneficiaries to file appeals timelier and receive faster 
resolution. Enabling beneficiaries to monitor the status of drug prior 
authorization requests submitted on their behalf is also consistent 
with section 1932(c)(1)(A) of the Act. Knowing within 1 business day 
that a prior authorization has been approved could enable a beneficiary 
to more promptly schedule or obtain care.
    Finally, section 1902(a)(7) of the Act requires that a state's plan 
for medical assistance provides safeguards which restrict the use or 
disclosure of information concerning applicants and beneficiaries,\253\ 
in relevant part, to purposes directly connected with the 
administration of the plan. Our implementing regulations in 42 CFR part 
431, subpart F set forth certain purposes that CMS has determined are 
directly connected to Medicaid state plan administration (42 CFR 
431.302) and requirements for states to safeguard Medicaid applicants' 
and beneficiaries' information in accordance with section 1902(a)(7) of 
the Act. Our regulations in 42 CFR part 431, subpart F include 
requirements for safeguarding the information, what types of 
information must be safeguarded, and when and how to release otherwise 
safeguarded information.
---------------------------------------------------------------------------

    \253\ Section 1902(a)(7) of the Act uses the term 
``recipients.'' For clarity, we have modified the term to 
``beneficiaries'' to be consistent with the terminology used in this 
proposed rule.
---------------------------------------------------------------------------

    Our proposal to require that the drug prior authorization data 
described in this section be shared via the Patient Access API would be 
consistent with the requirement that states may share these data only 
for purposes directly connected to the administration of the Medicaid 
state plan, since providing beneficiaries with their own data could 
directly affect their ability to receive appropriate Medicaid services, 
a permissible purpose listed in 42 CFR 431.302(c). As mentioned in the 
2024 CMS Interoperability and Prior Authorization final rule, giving a 
patient access to their own health information can make them a more 
active participant in ensuring they receive timely and appropriate care 
(89 FR 8785).
(2) Provider Access API
    For the Provider Access API, a requirement for states to include 
information about prior authorizations for drugs could improve states' 
ability to ensure that care and services are provided in a manner 
consistent with simplicity of administration, and to cover services 
more efficiently. The proposal would support efficient and prompt 
delivery of care, which would be in the beneficiaries' best interests. 
This proposal would also be expected to give providers better access to 
prior authorization decisions for care provided by other enrolled 
Medicaid providers, which would give a provider a more holistic view of 
a patient's care and reduce the likelihood of ordering duplicate or 
misaligned drugs. This could also facilitate easier and more informed 
decision-making by the provider and would therefore support efficient 
coverage decisions in the best interest of patients. The inclusion of 
drugs would result in a more complete picture of the patient to the 
provider at the point of care, which could improve the quality and 
efficiency of a patient visit, thus enabling the provider to treat more 
patients. These outcome and process efficiencies could help states 
fulfill their obligations to ensure prompt access to services that are 
in the best interest of beneficiaries, consistent with sections 
1902(a)(8) and (19) of the Act, and the efficiencies created for 
providers might help the state administer its Medicaid program more 
efficiently, consistent with section 1902(a)(4) of the Act. These 
analyses apply similarly to state Medicaid FFS programs and Medicaid 
managed care plans and delivery systems, so we are exercising our 
authority to adopt regulatory requirements for adding prior 
authorization data for all drugs to the Provider Access API for both 
state Medicaid FFS programs and Medicaid managed care plans.
    Finally, consistent with section 1902(a)(7) of the Act and our 
implementing regulations in 42 CFR part 431, subpart F, any request for 
beneficiary information via the Provider Access API would be from an 
enrolled Medicaid provider and for purposes directly connected with the 
administration of the state plan. An enrolled Medicaid provider would 
have a provider agreement with the state Medicaid agency in order to 
provide Medicaid benefits and services under its state plan. As such, 
enrolled Medicaid providers are part of the state's Medicaid program, 
assisting the state agency in carrying out core functions of the 
state's Medicaid state plan, providing benefits and services to 
beneficiaries. Therefore, the state Medicaid agency would not be 
required to obtain additional consent (beyond the beneficiary not 
opting out of sharing the specified data via the Provider Access API, 
as finalized in 42 CFR 431.61(a)(4)) from the beneficiary or their 
authorized representative, as generally required under 42 CFR 
431.306(d),\254\ prior to sharing the individual's information with a 
requesting Medicaid provider. However, the state Medicaid agency would 
continue to be required to provide the beneficiary or their authorized 
representative an opportunity to opt out of sharing the specified data 
via the Provider Access API, as finalized in the 2024 CMS

[[Page 19982]]

Interoperability and Prior Authorization final rule (89 FR 8817 and 
8978).\255\
---------------------------------------------------------------------------

    \254\ The regulation in 42 CFR 431.306(d) generally requires a 
state Medicaid agency to obtain permission from the beneficiary or 
their authorized representative, whenever possible, before 
responding to a request for information from an outside source.
    \255\ See 42 CFR 431.61(a)(4).
---------------------------------------------------------------------------

    While the beneficiary's permission would not be required under 42 
CFR 431.306(d) for the Provider Access API proposals we discuss here, 
other laws or regulations, such as the regulations that address the 
confidentiality of substance use disorder patient records in 42 CFR 
part 2, may require such permission.
(3) Payer-to-Payer API
    For the Payer-to-Payer API, these proposals are consistent with 
sections 1902(a)(4), (a)(8), and (a)(19) of the Act for the following 
reasons. First, because the Payer-to-Payer API is designed to enable 
efficient exchange of data between payers, we anticipate that adding 
information about prior authorizations for drugs would help state 
Medicaid FFS programs improve the efficiencies and simplicity of their 
own operations, consistent with sections 1902(a)(4) and (a)(19) of the 
Act. It could give Medicaid and CHIP agencies and their managed care 
plans access to more of their beneficiaries' information in a 
standardized manner and enable the state to then make that information 
available to providers and to patients through the Patient Access and 
Provider Access API. It could also reduce the amount of time needed to 
evaluate a patient's current care plan, which could in turn introduce 
efficiencies and improve care.
    As discussed in the 2022 CMS Interoperability and Prior 
Authorization proposed rule, if a state Medicaid FFS program has access 
to a previous payer's prior authorization decisions, the Medicaid 
program could choose to accept the existing decision and support 
continued patient care without requiring a new prior authorization or 
duplicate tests (87 FR 76284).
    This information exchange might also improve care continuity for 
beneficiaries who have concurrent coverage in addition to Medicaid by 
improving the coordination of health coverage they receive, reducing 
gaps, or duplication of coverage.
    Our proposal, if finalized, is expected to help states and Medicaid 
managed care plans furnish Medicaid services with reasonable promptness 
and in a manner consistent with beneficiaries' best interests, 
consistent with sections 1902(a)(8) and (a)(19) of the Act. A 
significant portion of Medicaid beneficiaries experience coverage 
changes and churn each year.\256\ Therefore, exchanging more 
information with a beneficiary's next payer could also better support 
care continuity for Medicaid beneficiaries. If states were to share 
information about Medicaid beneficiaries or former beneficiaries with 
their concurrent and next payers, they could support opportunities for 
improved care coordination for Medicaid beneficiaries and former 
beneficiaries. Exchanging information about Medicaid beneficiaries and 
former beneficiaries between payers might also reduce the amount of 
time needed to evaluate beneficiaries' current care plans, their health 
risks, and their health conditions at the time they enroll with the 
Medicaid program, as well as with another payer. This information 
exchange might be of particular value to improve care continuity for 
beneficiaries who might churn into and out of Medicaid coverage. The 
proposal could also improve the provision of Medicaid services, by 
potentially helping to ensure that Medicaid beneficiaries who may 
require coordinated services with concurrent payers could be identified 
and provided case management services, reduce duplication of drugs, and 
improve the coordination of care, as appropriate.
---------------------------------------------------------------------------

    \256\ Churning occurs when people lose Medicaid coverage and 
then re-enroll within a short period of time. Medicaid beneficiaries 
frequently experience churning. Sugar, S., Peters, C., Lew, N. D., & 
Sommers, B. D. (2021, April 12). Medicaid Churning and Continuity of 
Care: Evidence and Policy Considerations Before and After the COVID-
19 Pandemic. ASPE. Assistant Secretary For Planning And Evaluation. 
Retrieved from https://aspe.hhs.gov/sites/default/files/documents/5f6e4d78d867b6691df12d1512787470/medicaid-churning-ib.pdf.
---------------------------------------------------------------------------

    For Medicaid managed care plans, the proposed exchange of the 
patient's drug prior authorization requests and decisions would greatly 
enhance an MCO's, PIHP's, or PAHP's ability to fulfill its obligations 
under 42 CFR 438.208(b) to implement procedures to deliver care to and 
coordinate services for all enrollees, including coordinating services 
between settings of care, with services an enrollee receives from any 
other MCO, PIHP, or PAHP, with services an enrollee receives in FFS 
Medicaid, and with services an enrollee receives from community and 
social support providers. The proposed additional data provided via the 
Payer-to-Payer API in this rule would give Medicaid managed care plans 
more information needed to perform these required functions more 
easily, thus enhancing the effectiveness of the care coordination, and 
helping beneficiaries receive the most appropriate care in an effective 
and timely manner.
    (4) Reporting Provider Access, Payer-to-Payer, and Prior 
Authorization API Metrics
    We are also proposing to require state Medicaid agencies and 
Medicaid managed care plans to report Provider Access, Payer-to-Payer, 
and Prior Authorization APIs metrics to CMS annually. We believe that 
having these metrics would support CMS's oversight, evaluation, and 
administration of the Medicaid program, as it would allow us to 
evaluate beneficiary and provider use to these APIs. Use of these APIs 
could indicate that the policies are supporting program efficiencies 
and ensuring access to information in a timely and efficient way and in 
the best interest of beneficiaries, as intended, and as is consistent 
with sections 1902(a)(4) and (19) of the Act. Additionally, section 
1902(a)(6) of the Act requires Medicaid state plans to provide that the 
state Medicaid agency will make such reports, in such form and 
containing such information, as the Secretary may from time to time 
require. These metrics would serve as a report to evaluate the 
implementation and execution of the Provider Access, Payer-to-Payer, 
and Prior Authorization APIs.
c. CHIP
    Our proposed requirements in this section for CHIP generally fall 
under the authority in section 2101(a) of the Act, which states that 
the purpose of Title XXI of the Act is to provide funds to states to 
provide child health assistance to uninsured, low-income children in an 
effective and efficient manner that is coordinated with other sources 
of health benefits coverage. We believe the proposed requirements could 
strengthen states' abilities to fulfill these statutory obligations 
under Title XXI of the Act in a way that would recognize and 
accommodate the use of electronic information exchange in the health 
care industry today and would facilitate a significant improvement in 
the delivery of quality health care to CHIP beneficiaries.
    Additionally, the requirements to safeguard applicant and 
beneficiary information in 42 CFR part 431, subpart F (which implement 
section 1902(a)(7) of the Act) are also applicable to CHIP for each of 
the Access APIs through a cross reference in 42 CFR 457.1110(b). 
Finally, section 2107(b)(1) of the Act requires that state child health 
plans include an assurance that the state will collect the data, 
maintain the records, and furnish the reports to the Secretary, at the 
times and in the standardized format the Secretary may require in order 
to enable the Secretary to monitor state program administration and 
compliance and to evaluate and compare the effectiveness of state plans 
under this title.

[[Page 19983]]

(1) Patient Access API
    For the Patient Access API, this provision provides us with 
authority to adopt these requirements for CHIP because the proposed 
requirements increase the access of patients and of the parents/legal 
guardians (or personal representatives) of minor patients to their 
health information, which can improve the efficacy of CHIP programs, 
allow for more efficient communication and administration of services, 
and promote coordination across different sources of health benefits 
coverage.
    We believe that requiring CHIP agencies, as well CHIP managed care 
entities, to make CHIP beneficiaries' drug prior authorization data 
available to these beneficiaries or their personal representatives 
(usually the parent or guardian of a minor child) through the existing 
Patient Access API would ultimately lead to these beneficiaries or 
personal representatives accessing that information in a convenient, 
timely, and portable way. This improved access would help administer 
services effectively, efficiently, and in the best interests of 
beneficiaries, consistent with the requirements in section 2101(a) of 
the Act. We believe making these additional data available would result 
in better health outcomes and patient satisfaction and improve the cost 
effectiveness of the entire health care system, including CHIP.
    These proposals also align with section 2101(a) of the Act in that 
they also would improve the efficiency of CHIP programs. Adding 
information about drug prior authorization requests to the Patient 
Access API would allow beneficiaries or their personal representatives 
to easily obtain the status of prior authorization requests made on 
their behalf. This would in turn allow patients or their personal 
representatives to make scheduling decisions, and provide any missing 
information needed by a payer to reach a decision, which makes the 
prior authorization process more efficient, and ultimately streamlining 
the entire process.
(2) Provider Access API
    For the Provider Access API, when providers have access to more 
prior authorization information--namely, that information about drugs--
from payers or other health IT systems, they can provide higher quality 
care. Improving the quality of care aligns with section 2101(a) of the 
Act, which requires states to provide CHIP services (via either state 
CHIP FFS programs or CHIP managed care entities) in an effective and 
efficient manner. The more information a provider has to make informed 
decisions about a patient's care, the more likely it is that patients 
would receive care that best meets their needs. Additionally, providers 
could be more effective and efficient in their delivery of CHIP 
services by having direct access to prior authorization information. If 
a provider has more drug information about a patient prior to or at the 
point of care, the provider would be able to spend more time focused on 
the patient, rather than on their need to collect information. In 
addition, the information that providers do collect would not be based 
solely on patient or personal representative recall. This could save 
time, improve the quality of care, and increase the total amount of 
direct care provided to CHIP beneficiaries. When data are standardized, 
and able to be incorporated directly into the provider's EHR or health 
IT system, they can be leveraged as needed at the point of care by the 
provider and also can be used to support coordination across providers 
and payers. This is inherently more efficient, and ultimately, more 
cost-effective, as the information does not have to be regularly 
repackaged and reformatted to be shared or used in a valuable way. As 
such, the Provider Access API proposals also align with section 2101(a) 
of the Act in that these proposals could improve coordination between 
either CHIP agencies or CHIP managed care entities and other health 
coverage. For these reasons, we believe this proposal is in the best 
interest of the beneficiaries and within our long-established statutory 
authorities.
(3) Payer-to-Payer API
    For the Payer-to-Payer API, the current payer could use data from 
the previous payer to respond to a request for a prior authorization 
more effectively or accurately, because under this proposal, a new 
payer would have drug prior authorization information along with the 
currently required historical claims and clinical data upon which they 
may review a request with more background data. Access to more 
information about new patients could enable appropriate staff within 
the CHIP program, whether it is a state CHIP FFS program or CHIP 
managed care entity, to coordinate care and conduct care management 
more effectively because they would have more data available to make 
decisions for planning. In many cases, patients or their personal 
representatives do not remember the drugs they were prescribed or other 
possibly relevant encounters that could help payers manage their care. 
This proposal is consistent with the goal of providing more informed 
and effective care coordination, which could help to ensure that CHIP 
services are provided in a way that supports quality care, which aligns 
with section 2101(a) of the Act.
    Additionally, the requirements to safeguard applicant and 
beneficiary information in 42 CFR part 431, subpart F are also 
applicable to CHIP through a cross reference in 42 CFR 457.1110(b). As 
discussed previously for Medicaid, CHIP agencies' data exchange through 
the Access APIs would be related to providing services to 
beneficiaries, which is described in 42 CFR 431.302(c) as a purpose 
directly related to state plan administration.
(4) Reporting Provider Access, Payer-to-Payer, and Prior Authorization 
API Metrics
    Finally, proposing to require state CHIP agencies and CHIP managed 
care entities to report Provider Access, Payer-to-Payer, and Prior 
Authorization API metrics to CMS annually would help states and CMS 
understand how these APIs can be used to continuously improve the 
effectiveness and efficiency of state CHIP operations by providing 
information about their use, which is an indication of the APIs' uptake 
among patients (or their personal representatives) and providers, 
including how many only use it for a one-time setup, consistent with 
section 2107(b)(1) of the Act. The more we understand about the use of 
the Provider Access, Payer-to-Payer, and Prior Authorization APIs, the 
better we can assess that the APIs are leading to improved operational 
efficiencies and providing information to beneficiaries (or their 
personal representatives) and providers in a way that supports their 
best interests.
d. Qualified Health Plan Issuers on the Federally-facilitated Exchanges
    For QHP issuers on the FFEs, we propose these new requirements for 
the Access APIs under our authority in section 1311(e)(1) of the 
Affordable Care Act. Section 1311(e)(1)(A) of the Affordable Care Act 
requires that Exchanges only certify plans as QHPs if they meet the 
requirements for certification promulgated by the Secretary under 
section 1311(c)(1) of the Affordable Care Act, while section 
1311(e)(1)(B) of the Affordable Care Act provides discretion to certify 
QHPs if the Exchange determines that making available such plans 
available is in the interests of qualified individuals and qualified 
employers in the state or states in which such Exchange operates.

[[Page 19984]]

(1) Patient Access API
    For the Patient Access API, we believe generally that certifying 
only health plans that take steps to make qualified individuals' and 
qualified employers' prior authorization requests for drugs and related 
clinical documentation available through interoperable technology 
(unless they have been granted an exception under 45 CFR 156.221(i)) 
would ultimately lead to these qualified individuals and qualified 
employers having access to that information in a convenient, timely, 
and portable way, which is in qualified individuals' and qualified 
employers' best interests. Adding information about prior authorization 
requests for drugs to the Patient Access API would allow qualified 
individuals and qualified employers to more easily obtain the status of 
prior authorization requests submitted on their behalf and use that 
information effectively to make more informed decisions about their 
health care, improve the efficiency of accessing and scheduling 
services, and, if needed, provide missing information needed by the QHP 
issuer on the FFEs to reach a decision on a prior authorization 
request. This could allow QHP issuers on the FFEs to more promptly 
address drug prior authorization requests. This would also facilitate 
timelier and potentially more successful initial prior authorization 
requests. We encourage SBEs, including SBE-FPs, to consider whether a 
similar requirement should be applicable to issuers participating in 
their Exchanges.
(2) Provider Access API
    For the Provider Access API, we believe that certifying only health 
plans that make enrollees' health information available to their 
providers (unless they have been granted an exception under 45 CFR 
156.222(c)) is in the interests of enrollees. Giving providers access 
to their patients' information supplied by QHP issuers on the FFEs 
would ensure that providers are better positioned to provide enrollees 
with seamless and coordinated care and could reduce duplicate 
prescriptions or delays in care and diagnosis. Access to the patient's 
more complete medical information could also maximize the efficiency of 
an enrollee's office visits. We encourage SBEs, including SBE-FPs, to 
consider whether a similar requirement should be applicable to issuers 
participating in their Exchanges.
(3) Payer-to-Payer API
    For the Payer-to-Payer API, we believe that adding more information 
to this existing API would reduce administrative burden and result in 
more timely and efficient care coordination and responses to prior 
authorization requests. We believe it is in the interest of qualified 
individuals and qualified employers that QHP issuers on FFEs continue 
to have systems in place that send information that is important to 
care coordination with departing enrollees, and that QHP issuers on 
FFEs also have systems in place to receive such information from payer 
to payer on behalf of new and concurrent enrollees, as appropriate and 
consistent with the proposals in this section. Therefore, we believe 
certifying health plans that make enrollees' health information 
available to other payers (unless they have been granted an exception 
under 45 CFR 156.222(c)) in a convenient, timely, and portable way is 
in the interests of qualified individuals and qualified employers in 
the state in which an FFE operates.
(4) Reporting Provider Access, Payer-to-Payer, and Prior Authorization 
API Metrics
    Finally, proposing to require QHP issuers on the FFEs to report 
Provider Access, Payer-to-Payer, and Prior Authorization API metrics to 
CMS annually would help CMS assess the effect these APIs are having on 
enrollees and providers. In addition, those data would inform how CMS 
could either enhance the policies or improve access or usage, whether 
through activities, such as additional patient and provider education, 
or additional rulemaking. These data could help CMS understand how best 
to leverage these APIs, improve meaningful patient and provider access 
to data, ensure these requirements are being met efficiently, and are 
adding value to QHP operations, including leading to the efficiencies 
intended.

G. Open Payments Civil Monetary Penalties

1. Open Payments Policies
a. Background
    The Open Payments program\257\ is a statutorily mandated program 
that promotes the transparency of pharmaceutical and medical device 
industry financial relationships with certain types of health care 
providers by providing the public with certain payment or transfer of 
value information. Section 1128G of the Act, and implementing 
regulations promulgated in the ``Medicare, Medicaid, Children's Health 
Insurance Programs; Transparency Reports and Reporting of Physician 
Ownership or Investment Interests'' final rule (78 FR 9458) 
(hereinafter referred to as the ``Open Payments final rule''), which 
appeared in the Federal Register on February 8, 2013, require 
manufacturers of covered drugs, devices, biologicals, or medical 
supplies (hereafter referred to as ``applicable manufacturers''), as 
well as applicable GPOs, to annually submit information for the 
preceding calendar year about certain payments or other transfers of 
value made to ``covered recipients,'' originally defined as physicians 
and teaching hospitals.\258\ On October 24, 2018, the SUPPORT Act was 
signed into law. Section 6111 of the SUPPORT Act broadened the 
definition of ``covered recipient'' in section 1128G(e)(6)(A) of the 
Act to add physician assistants (PAs), nurse practitioners (NPs), 
clinical nurse specialists (CNSs), certified registered nurse 
anesthetists (CRNAs), anesthesiologist assistants, and certified nurse 
midwives (CNMs). The rulemaking in 84 FR 62568, which appeared in the 
Federal Register on November 15, 2019, codified that definition in 42 
CFR 403.902 and made additional reporting clarifications and updated 
several Nature of Payment Categories and standardized product 
information such as mandating unique device identifiers.
---------------------------------------------------------------------------

    \257\ See 42 U.S.C. 1320a.
    \258\ See 42 CFR 403.902.
---------------------------------------------------------------------------

    Payments or other transfers of value that must be reported include, 
but are not limited to, such things as research-related payments, 
honoraria, gifts, travel expenses, meals, grants, and other 
compensation.\259\ The type of information required to be reported 
includes, but is not limited to, the date and amount of the payment or 
other transfer of value, identifying information about the covered 
recipient, and details about products associated with the 
transaction.\260\ When a payment or other transfer of value is related 
to marketing, education, or research specific to a covered drug, 
device, biological, or medical supply, the name of that covered drug, 
device, biological, or medical supply also must be reported.\261\
---------------------------------------------------------------------------

    \259\ See 42 CFR 403.904(e)(2).
    \260\ See 42 CFR 403.904 (c).
    \261\ See 42 CFR 403.904(c)(8).
---------------------------------------------------------------------------

    Section 1128G of the Act establishes certain minimum dollar 
thresholds for required reporting of individual and aggregate payments 
or transfers of value. To determine if multiple small individual 
payments or other transfers of value made to a covered recipient exceed 
the de minimis reporting threshold, applicable manufacturers and

[[Page 19985]]

applicable GPOs must aggregate all individual payments made across all 
payment categories within a given reporting year. The initial (calendar 
year 2013) reporting thresholds were $10 for individual payments or 
other transfers of value and $100 for aggregated payments. The statute 
requires the reporting threshold to be annually increased by the 
consumer price index for the preceding 12-month period ending in June 
of the previous year.\262\ The calendar year 2025 thresholds are $13.46 
for individual payments or other transfers of value and $134.54 for 
aggregate payments.\263\
---------------------------------------------------------------------------

    \262\ Despite the language of section 1128G(e)(10)(B)(i) of the 
Act that says ``[f]or calendar years after 2012,'' we explained in 
the rulemaking that, ``[g]iven the timing of this final rule, we 
have decided to begin increasing the de minimis thresholds for 
reporting in CY 2014, and retain the statutory de minimis thresholds 
($10 and $100) for reporting in CY 2013.''
    \263\ See 42 CFR 403.904(h)(2)(iii).
---------------------------------------------------------------------------

    The Open Payments program yields information about providers for 
the general public and researchers may use Open Payments data to study 
whether there may be any relation between provider behavior and their 
financial relationships. This information is collected and published on 
an annual cycle, with the data annually becoming public by June 30. The 
Open Payments program has made public more than 118.2 million records 
between its August 2013 start and the June 2024 publication cycle, 
enabling significant transparency into applicable exchanges of value. 
We are committed to stakeholder engagement in an effort to limit the 
Open Payments program reporting burden and improve clarity for the 
public. The estimated burden of these reporting requirements, as 
outlined under the Office of Management and Budget (OMB) control number 
0938-1237, is approximately 1.9 million hours over the course of 1 
year. Additional background about the program and guidance, including 
frequently asked questions, regarding how the program works and what 
type of information is required to be reported is available at https://www.cms.gov/priorities/key-initiatives/open-payments.
    Section 1128G(e)(10)(A) of the Act defines the term ``payment or 
other transfer of value'' as a transfer of anything of value, though 
some exclusions apply, while sections 1128G(e)(4) and (5) of the Act 
define covered drugs, devices, biologicals, or medical supplies as 
those covered under Medicare, a state plan under Medicaid or CHIP (or a 
waiver of either such state plan). Section 1128G(a) of the Act requires 
applicable manufacturers and applicable GPOs to disclose any ownership 
or investment interests in such entities held by physicians or 
physicians' immediate family members, as well as information on any 
payments or other transfers of value provided to such physician owners 
or investors.
    As a statutorily mandated public reporting program, our ability to 
validate the timeliness, completeness, and accuracy of the Open 
Payments records that entities are required to report to us is crucial 
to ensuring data accuracy and reliability, and hence, the value of the 
program itself. Section 1128G(b)(1) of the Act authorizes penalties for 
non-compliance and gives us the authority to impose CMPs for instances 
of ``failure to report,'' for records that were not reported to CMS. 
Because it is axiomatic that CMS cannot find unreported information in 
records that are reported, we interpret the language of section 
1128G(b)(1) of the Act, which provides that any applicable manufacturer 
or applicable GPO ``that fails to submit information required . . . in 
a timely manner in accordance with rules or regulations promulgated to 
carry out such subsection, shall be subject to a civil money penalty,'' 
as encompassing our ability to impose a CMP upon an applicable 
manufacturer or applicable GPO that fails to timely submit, in 
accordance with our regulations, required information, including the 
information requested to perform an audit.
    We codified our authority to require audit responsiveness via 
regulation in 42 CFR 403.912(e)(2), which states that ``HHS, CMS, 
[Office of Inspector General (OIG)] or their designees may audit, 
inspect, investigate and evaluate any books, contracts, records, 
documents, and other evidence of applicable manufacturers and 
applicable group purchasing organizations that pertain to their 
compliance with the requirement to timely, accurately or completely 
submit information in accordance with the rules established under this 
subpart.'' The Open Payments final rule preamble repeatedly mentioned 
audits because access to such information is essential to facilitating 
our ability to adequately oversee regulated entities' Open Payments 
program compliance.\264\
---------------------------------------------------------------------------

    \264\ For example, per the Open Payments final rule, ``in order 
to facilitate audits and enforcement, applicable manufacturers and 
applicable GPOs must maintain all books, records, documents, and 
other materials sufficient to enable an audit, evaluation or 
inspection of the applicable manufacturer's or applicable GPO's 
compliance with the requirements in section 1128G of the Act and the 
implementing regulations.'' (78 FR 9506-78 FR 9507).
---------------------------------------------------------------------------

    To facilitate audits, we finalized in the Open Payments final rule 
a requirement under 42 CFR 403.912(e)(1) that applicable manufacturers 
and applicable GPOs must maintain all books, records, documents, and 
other materials sufficient to enable an audit, evaluation or inspection 
of the applicable manufacturer's or applicable GPO's compliance with 
the requirements in section 1128G of the Act and the implementing 
regulations. To ensure that those materials are available for a 
sufficient period to allow audits, we require applicable manufacturers 
and applicable GPOs to maintain these books, records, documents, and 
other materials for a period of at least 5 years from the date the 
payment or other transfer of value, or ownership or investment interest 
is published publicly on the website.\265\
---------------------------------------------------------------------------

    \265\ See 42 CFR 403.912(e)(1)(ii).
---------------------------------------------------------------------------

b. Proposal to Add a Definition of ``Failure to Report'' in 42 CFR 
403.902
    The Open Payments final rule preamble frequently mentioned audits 
because access to this information is essential to facilitating our 
ability to adequately oversee regulated entities' Open Payments program 
compliance. CMS began exercising the Open Payments program audit 
authority in 2022 by requiring certain reporting entities to provide 
relevant documentation pertaining to their reported records--such as 
copies of checks, written agreements, or a general ledger--to verify 
that payments had been reported accurately. But upon attempting to 
conduct such audits, certain reporting entities thwarted our efforts by 
refusing to comply with our audit requests and rendering it impossible 
for us to evaluate their Open Payments reporting compliance. We must 
remedy that to ensure we can effectively oversee Open Payment reporting 
compliance, and, therefore, in this proposed rule we propose certain 
new measures to refine the effectiveness of our auditing authority.
    To do that, first we propose to include in section 42 CFR 403.902 a 
definition of ``failure to report,'' which would be foundational to 
enabling us to impose a CMP upon a reporting entity that failed to 
provide records pursuant to a CMS audit. Our rationale is succinct: the 
information reported by entities statutorily required to report to the 
Open Payments program can be verified by an audit, but in administering 
the program we currently have no way to compel an Open Payment program 
reporting entity to comply with our audit request. Absent our ability 
to issue

[[Page 19986]]

a CMP for a failure to produce requested audit documents, we would have 
no adequate enforcement route should a reporting entity fail to comply 
with an audit request.
    The phrase ``failure to report''--that we borrow from the statute 
in section 1128G(b)(1)(A) of the Act--is not presently a defined term 
within the definitions section of our rules in 42 CFR 403.902, but we 
do explicitly apply the ``failure to report'' concept in 42 CFR 
403.912(a)(1) which refers to the failure ``to timely, accurately or 
completely report the information required in accordance with the rules 
established under this subpart'' (and auditing already is encompassed 
in the subpart in 42 CFR 403.912(e)(2). To ensure clarity that we not 
only require applicable manufacturers and applicable GPOs to provide us 
the specified information required when reporting a record, but also 
that they furnish the required item of information that CMS determines 
necessary when it conducts an Open Payment audit, we believe that we 
must define ``failure to report'' in 42 CFR 403.902, and propose here 
to do so. The proposed definition is based on the existing reference in 
42 CFR 403.912(a)(1), and its scope would encompass the information 
already required to be provided to CMS under the Open Payment 
regulations. This addition would help clarify that an Open Payment 
reporting party's refusal to comply with or respond to an audit request 
would carry consequences.\266\
---------------------------------------------------------------------------

    \266\ This includes our authority to audit books, contracts, 
records, documents, ledgers, and other evidence of compliance with 
reporting requirements that reporting entities must maintain. See 42 
CFR 403.912(e)(2).
---------------------------------------------------------------------------

    If finalized as proposed, our proposal would encourage Open Payment 
reporting party compliance with the exercise of our auditing oversight 
authority. Absent compliance, for each requested document that an 
entity would fail to provide we could impose a CMP under a ``failure to 
report'' category (limited by the statutory ceiling and floor amounts 
per record and per program year). This would align with the current 
regulation in 42 CFR 403.912(e) as the auditable documentation would 
correspond to a reported or reportable record. We do not propose to 
alter the existing CMP calculation methodology and would continue to 
calculate CMPs using records and their documents on a per-record 
``failure to report'' basis as required by section 1128G(b) of the Act. 
This proposed rule would define the information applicable 
manufacturers and applicable GPOs are required to timely, accurately, 
and completely provide in the course of reporting information to HHS, 
CMS, OIG or their designees.
    Explicitly defining ``failure to report'' to make clear that it 
includes reporting entities' furnishing the required item of 
information that CMS determines necessary when it conducts an Open 
Payment audit would rectify this shortcoming, clarify that there would 
be consequences for applicable manufacturers and applicable GPOs that 
refuse to participate in a program audit, and enhance program 
compliance. Reporting entities are already required to keep contact 
information updated, per 42 CFR 403.908(c)(3), and this information 
would be used to notify audited entities. We propose to make it 
unambiguously clear that CMS may impose a CMP should an applicable 
manufacturer or applicable GPO fail to grant timely access to documents 
for the purposes of an audit authorized by 42 CFR 402.912(e)(2). We 
would accomplish this by adding a definition for ``failure to report'' 
in 42 CFR 403.902.
    We propose to define a ``failure to report'' in 42 CFR 403.902 to 
include a failure to submit requested information, to the Open Payments 
program per existing requirements in 42 CFR 403.912. This definition 
would include a failure to timely, accurately, and completely provide 
to HHS, CMS, OIG or their designees the documentation that is required 
according to program requirements, including records that are subject 
to CMS's audit authority in 42 CFR 403.912(e)(2). We propose that an 
applicable manufacturer's or applicable GPO's failure to provide, 
within 30 calendar days of the date of the audit request, the documents 
or other listed items requested by CMS or its agents, would constitute 
a ``failure to report.'' We propose that each document requested but 
not provided to CMS within the timeframe would be subject to the CMP 
calculation within the annual cap.\267\ We believe that this 30-day 
deadline would not affect any existing requirements, such as the 
requirement to attest to records by the 90th day of the calendar year 
or to report any errors or omissions immediately upon confirmation of 
the error or omission.
---------------------------------------------------------------------------

    \267\ See 45 CFR 102.3 for annual calculation. For 2025, the 
non-compliance per-record minimum is $1,406 and the maximum is 
$14,067, with a per-year cap of $211,008. The knowing minimum per-
record is $14,067 and the maximum is $140,674, with a per-year cap 
of $1,406,728.
---------------------------------------------------------------------------

    We propose that a CMP associated with a ``failure to report'' for 
the purposes of an audit would explicitly be considered a violation of 
reporting requirements, including the requirement to maintain documents 
for the purposes of audits in 42 CFR 403.912(e), and therefore would be 
subject to the monetary limitations imposed by the Open Payments 
statute in section 1128G(b)(2) of the Act. If finalized as proposed, 
the authority to impose a CMP for documents requested for the purposes 
of an audit that applicable manufacturers or applicable GPO fail to 
provide within 30 calendar days of the request would begin on the 
effective date of the final rule. This proposal does not alter the 
definition of ``know, knowing, or knowingly'' and therefore a ``failure 
to report'' may escalate to a ``knowing failure to report'' under the 
existing circumstances.
    In summary, we request comment on our proposals, and specifically 
on the following:
     The proposal to add a definition for ``failure to report'' 
in 42 CFR 403.902, which would allow CMS to impose a CMP on applicable 
manufacturers or applicable GPOs should either of those entities fail 
to grant timely access (within 30 calendar days of the date of the 
audit request) to any books, contracts, records, documents, and other 
evidence sufficient to enable the audit, evaluation, and inspection of 
the records for the purposes of an audit authorized by 42 CFR 
402.912(e)(2).
     The proposal to become effective beginning on the 
effective date of the final rule.
2. Statutory Authorities
    Four legal authorities ground our proposals:
     Sections 1102 and 1871 of the Act, which provide general 
authority for the Secretary to prescribe regulations for the efficient 
administration of the Medicare program.
     Section 1861 of the Act, which defines providers and 
suppliers.
     Section 1128G of the Act, as amended by section 6111 of 
the SUPPORT Act, which requires applicable manufacturers of drugs, 
devices, biologicals, or medical supplies covered under Medicare or a 
state plan under Medicaid or CHIP to report annually to the Secretary 
certain payments or other transfers of value to physicians and teaching 
hospitals, and to PAs, NPs, CNSs, CRNAs, and CNMs for information 
required to be submitted under section 1128G of the Act on or after 
January 1, 2022.

H. Modifications to HIPAA Standards Related to Prior Authorization

1. Background
    The Health Insurance Portability and Accountability Act of 1996 
(HIPAA)

[[Page 19987]]

(Pub. L. 104-191, August 21, 1996) requires the Secretary to adopt 
standards for electronically conducting certain health care 
administrative transactions between certain entities. The proposals 
herein would, if finalized as proposed, marks a sea change in HIPAA 
Administrative Simplification as the first time we have proposed 
adopting Health Level Seven (HL7[supreg]) Fast Healthcare 
Interoperability Resources (FHIR[supreg]) standards. We believe the 
standards world is changing and aim to keep pace.
    Section 1172(a) of the Act applies HIPAA Administrative 
Simplification transaction standards to health plans, health care 
clearinghouses, and health care providers that electronically transmit 
health information in connection with those transactions, collectively 
referred to as HIPAA covered entities.\268\ HHS's proposals in this 
section pertain to two HIPAA transactions, the ``referral certification 
and authorization'' transaction in 45 CFR part 162, subpart M, and the 
``eligibility for a health plan'' transaction in 45 CFR part 162, 
subpart L. Importantly, unlike CMS's proposals discussed elsewhere in 
this proposed rule that would apply only to impacted payers (as that 
term is defined in section I.A. in the proposed rule and used 
throughout other sections of this rule), the proposals in this HHS 
section would apply to all HIPAA covered entities.
---------------------------------------------------------------------------

    \268\ See 45 CFR 160.103 for the definition of a HIPAA covered 
entity.
---------------------------------------------------------------------------

    The HIPAA statutory paradigm contemplates that processes and 
standards continue to evolve, and as such, paves the way for such 
change by speaking to additions and modifications to standards and 
requiring periodic review processes to ensure standards are continually 
updated and improved.\269\ To encourage innovation and promote the 
maturation of new standards, in the ``Health Insurance Reform: 
Standards for Electronic Transactions final rule'' (hereinafter 
referred to as the ``2000 Standards for Electronic Transactions final 
rule''), which appeared in the August 17, 2000, Federal Register (65 FR 
50312) we established an exceptions process by which an organization 
may request an exception from the adopted standard to test a proposed 
modification in 45 CFR 162.940 (65 FR 50343). The exceptions process 
enables entities to test new standards, which permits us to evaluate 
real-world results, and much of the discussion herein is framed around 
testing results from the exception granted to the HL7 Da Vinci Project 
that was authorized pursuant to that process.
---------------------------------------------------------------------------

    \269\ See, for example, sections 1173(i) and 1174(b) of the Act.
---------------------------------------------------------------------------

2. The Relevant Transactions and Definitions
a. Referral Certification and Authorization Transactions
    Prior authorization is the process by which a health care provider 
obtains approval from a health plan before rendering certain items, 
services, or drugs to a patient. Health plans establish prior 
authorization requirements to help control costs and ensure payment 
accuracy by verifying, before they are rendered, that certain items, 
services, or drugs are medically necessary for the specific patient, 
meet coverage criteria, and are consistent with standards of care.
    Prior authorization is not a single transmission, but an 
interactive process that fundamentally comprises two parts--a prior 
authorization request from a health care provider and a prior 
authorization decision issued by a health plan. However, it may also 
involve intermediate information exchanges. For instance, a health plan 
may transmit a request for clarification or additional documentation, 
and health care providers would transmit responses before a final 
health plan determination. Each such step would occur within the scope 
of the standards we propose here. Although prior authorization can 
serve an important function in the health care system by improving 
utilization management and controlling costs, effectuating it often 
involves burdensome processes. Specifically, issues with complex health 
plan policies, limited use of electronic standards, and other technical 
barriers can create workflow challenges and burden health care 
providers and their staff with challenging requirements that lead to 
delays in the provision of medically necessary care and can compromise 
patient safety and health outcomes.\270\

authorization physician survey. Retrieved from https://www.ama-assn.org/system/files/prior-authorization-survey.pdf.
---------------------------------------------------------------------------

    Section 1173(a) of the Act requires the Secretary to adopt HIPAA 
standards and data elements for nine specified transactions, including 
the ``referral certification and authorization'' transaction in section 
1173(a)(2)(I) of the Act. We have promulgated standards to conduct the 
transmissions composing the electronic prior authorization process at 
45 CFR 162, subpart M, the ``referral certification and authorization'' 
transaction. As described in 45 CFR 162.1301, the ``referral 
certification and authorization'' transaction comprises the following 
transmissions: (1) a request from a health care provider to a health 
plan for the review of health care to obtain an authorization for a 
health care service for a patient; (2) a request from a health care 
provider to a health plan to obtain authorization for referring a 
patient to another health care provider; and (3) a response from a 
health plan to a health care provider to a request described in (1) or 
(2).
    In the 2000 Standards for Electronic Transactions final rule, the 
Secretary adopted standards for eight electronic health care 
transactions, including ``referral certification and authorization.'' 
There, the Secretary adopted, in 45 CFR 162.1302, the Accredited 
Standards Committee (ASC) X12N 278--Health Care Services Review--
Request for Review and Response, Version 4010 transaction standard for 
dental, professional, and institutional ``referral certification and 
authorization'' transactions (65 FR 50341). HHS amended the standard in 
45 CFR 162.1302(b)(2), to include the Addenda to the Electronic Data 
Interchange (EDI) Transaction Set IG for X12N 278 Health Care Services 
Review Request for Review and Response, Version 4010 in the ``Health 
Insurance Reform: Modifications to Electronic Data Transaction 
Standards and Code Sets'' final rule (68 FR 8381), which appeared in 
the Federal Register on February 20, 2003.\271\ Subsequently, the 
Secretary adopted, in 45 CFR 162.1302(b)(2)(ii), the updated ASC X12 
Standards for EDI Technical Report Type 3--Health Care Services 
Review--Request for Review and Response, Version 5010 and Errata (X12N 
278 transaction standard) in the ``Health Insurance Reform; 
Modifications to the Health Insurance Portability and Accountability 
Act (HIPAA) Electronic Transaction Standards'' final rule (74 FR 3296), 
which appeared in the Federal Register on January 16, 2009.

    Notably, the ``referral certification and authorization'' 
transaction, and the transmissions it comprises, includes, but is not 
limited to, prior authorization. Aside from prior authorization, the 
``referral certification and authorization'' transaction's scope may 
pertain to many different health care events, treatment authorizations, 
specialty referrals, pre-admission certifications, certifications for 
health

care services (such as home health and ambulance), extension of 
certifications, and certification appeals.\272\ Because the ``referral 
certification and authorization'' transaction, and the transmissions it 
comprises, pertain to more than just prior authorization, and because 
some of the proposals herein pertain only to prior authorization, we 
propose in 45 CFR 162.103 to define prior authorization to mean (1) 
transmissions described in 45 CFR 162.1301(a) used by health care 
providers to obtain authorization for health care; \273\ and (2) 
transmissions described in 45 CFR 162.1301(c) used by health plans to 
respond to such requests.

to the health of an individual. Health care includes, but is not 
limited to, the following: (1) Preventive, diagnostic, therapeutic, 
rehabilitative, maintenance, or palliative care, and counseling, 
service, assessment, or procedure with respect to the physical or 
mental condition, or functional status, of an individual or that 
affects the structure or function of the body; and (2) Sale or 
dispensing of a drug, device, equipment, or other item in accordance 
with a prescription (see 45 CFR 160.103).
---------------------------------------------------------------------------

    These are the same transmissions, within the ambit of the 
``referral certification and authorization'' transaction, for which we 
proposed an attachment standard in the ``Administrative Simplification: 
Adoption of Standards for Health Care Attachments Transactions and 
Electronic Signatures, and Modification to Referral Certification and 
Authorization Transaction Standard proposed rule'' (87 FR 78438) 
(hereinafter referred to as the ``2022 HIPAA Standards for Health Care 
Attachments proposed rule''), which appeared in the Federal Register on 
December 21, 2022. Public comments opposing our proposed prior 
authorization attachment standard led us not to finalize it when we 
finalized that proposed rule in the ``Administrative Simplification: 
Adoption of Standards for Health Care Attachments Transactions and 
Electronic Signatures, and Modification to Referral Certification and 
Authorization Transaction Standard final rule'' (91 FR 14350) 
(hereinafter referred to as the ``2026 HIPAA Standards for Health Care 
Attachments final rule''), which appeared in the Federal Register on 
March 24, 2026.
    In that proposed rule, we proposed to adopt the X12N 275 attachment 
standard for ``health care claims or equivalent encounter information'' 
transactions and ``referral certification and authorization'' 
transactions. However, commenters to that proposed rule overwhelmingly 
and persuasively counseled us against finalizing the proposed X12N 275 
attachment standard for prior authorization transactions for which the 
X12N 278 is the transaction standard. Commenters cited concerns 
including limited industry experience implementing the X12N 275 
attachment standard for prior authorization transactions, variability 
in current prior authorization workflows, and potential conflict with 
other federal interoperability initiatives requiring FHIR-based 
standards to support Prior Authorization application programming 
interface (API) capabilities. Specifically, commenters asserted that 
previous attempts to leverage the X12N 275 attachment standard to 
support prior authorizations had failed and the X12N 278 transaction 
standard itself has never fully been embraced or implemented in the 
industry. Commenters added that while the X12N 275 attachment standard 
supports the types of attachments used with ``health care claims or 
equivalent encounter information'' transactions, it does not support 
the full scope of file types that may be attached to prior 
authorization transactions, such as FHIR questionnaires. Commenters 
urged us to consider FHIR standards, both for attachments and the 
underlying prior authorization transactions, to align with separate CMS 
rulemaking in the 2024 CMS Interoperability and Prior Authorization 
final rule. We agreed with commenters that efficient, cost-effective, 
simplified standards would be impeded by mismatches between HHS 
requirements under HIPAA and CMS requirements under its 
interoperability rulemaking.
    In this proposed rule, we propose to adopt the HL7 FHIR standard 
and certain FHIR IGs for prior authorization transactions. Importantly, 
our proposals address prior authorization transactions between health 
care providers and health plans; \274\ we are not proposing changes to 
the adopted standards for retail pharmacy drugs, for which the adopted 
standards are developed and maintained by NCPDP. This proposal aligns 
with the overall sentiment that commenters articulated in the 2026 
HIPAA Standards for Health Care Attachments final rule.
---------------------------------------------------------------------------

    \274\ Nothing precludes such transactions from being 
intermediated by clearinghouses, though traditionally they have not 
largely engaged in that role for prior authorization.
---------------------------------------------------------------------------

    In addition, and in the alternative, we are proposing to adopt the 
proposed standards for all ``referral certification and authorization 
transactions'' described in 45 CFR 162.1301, including those related to 
referral certification, as the FHIR standards we are proposing herein 
are capable of performing referral certification as well as 
authorization transmissions.
b. Eligibility for Health Plan Transaction
    Prior to submitting a request for prior authorization, health care 
providers must first determine whether prior authorization is required, 
and, if so, the health plan's documentation requirements that are 
required to obtain an approval. That antecedent for prior authorization 
falls in the scope of the HIPAA ``eligibility for a health plan'' 
transaction, which describes a health care provider's inquiry to a 
health plan (or a health plan's inquiry to another health plan) for 
eligibility, coverage, or benefits information for a patient, and the 
constituent transmissions described in 45 CFR 162.1201. In 45 CFR 
162.1202(a)(2), the Secretary adopted standards for the dental, 
professional, and institutional ``eligibility for a health plan'' 
transaction, specifically the ASC X12N 270/271 Health Care Eligibility 
Benefit Inquiry and Response transaction standard (X12N 270/271 
transaction standard). The ``eligibility for a health plan'' 
transaction serves multiple purposes, and in this proposed rule we are 
proposing to modify the standard for that transaction only when an 
inquiry and response are used to determine whether prior authorization, 
as HHS proposes to define that term in 45 CFR 162.103, is required. Our 
proposals would not alter the standards for other ``eligibility for a 
health plan'' transactions described in 45 CFR 162.1202 unrelated to 
prior authorization, for which the adopted standard would remain the 
X12N 270/271 transaction standard.
    Section 1173(g) of the Act requires the Secretary to adopt a single 
set of operating rules for each adopted HIPAA transaction with the goal 
of creating as much uniformity in the implementation of the electronic 
standards as possible. We have not yet adopted operating rules for the 
``referral certification and authorization'' transaction, but have 
adopted operating rules associated with the present X12N 270/271 
transaction standard for the ``eligibility for a health plan'' 
transaction. We are not proposing operating rules for the proposed 
subset of ``referral certification and authorization'' transactions 
because, unlike existing X12N transaction standards, the proposed FHIR 
base

[[Page 19989]]

standard \275\ and IGs themselves specify all the necessary operating 
requirements so they do not require operating rules. Consistent with 
that, we propose amending 45 CFR 162.1203 to specify that the existing 
operating rules associated with ``eligibility for a health plan'' 
transactions would exclude prior authorization-related transmissions, 
and explain that they would continue to apply to other ``eligibility 
for a health plan'' transactions that would continue to utilize the 
X12N 270/271 transaction standard.
---------------------------------------------------------------------------

    \275\ The FHIR standard, adopted by the Secretary as the ``API 
base standard'' in 45 CFR 170.215(a), is a base set of modular 
components called ``resources'' that serve as the foundation to the 
FHIR framework, and is commonly referred to as the FHIR base 
standard.
---------------------------------------------------------------------------

    In summary, HHS requests comment on its proposals summarized in 
section II.H.10. of this proposed rule, which includes the proposals 
discussed above, and the CFR citations listed in Table 11.
3. The Proposed FHIR Standards
    Based on the recommendations of the National Council for Vital and 
Health Statistics (NCVHS), the positive results of the HL7 Da Vinci 
Project's testing discussed herein, consultation with HL7 International 
as a DSMO, extensive public comment to various notices of HHS and CMS 
proposed rulemaking, and our own analysis, we are proposing a 
modification to the dental, professional, and institutional ``referral 
certification and authorization'' transaction standard for 
transmissions related to prior authorization to replace the present 
X12N 278 transaction standard with the FHIR standard. We propose to add 
a new 45 CFR 162.1302(g)(2) that would adopt the following 
specifications as the standard for the ``referral certification and 
authorization'' transactions within the contours of our proposed 
definition of prior authorization. Our proposals to adopt specific 
versions of the following specifications are discussed further later in 
this section:
     The HL7 FHIR Standard,
     HL7 FHIR US Core IG (US Core IG),
     HL7 Substitutable Medical Applications, Reusable 
Technologies (SMART) Application Launch Framework IG (SMART App Launch 
IG),
     HL7 FHIR Da Vinci Coverage Requirements Discovery IG (CRD 
IG),
     HL7 FHIR Da Vinci Documentation Templates and Rules IG 
(DTR IG), and
     HL7 FHIR Da Vinci Prior Authorization Support IG (PAS IG).
    In addition, in a new 45 CFR 162.1202(f)(2)(i), we propose adopting 
the following specifications as the standards for ``eligibility for a 
health plan'' transactions for dental, professional, and institutional 
health care eligibility inquiry and response, when used to determine 
whether prior authorization is required:
     The HL7 FHIR Standard,
     US Core IG,
     SMART App Launch IG, and
     CRD IG.
    Collectively, the proposed standards would enable the use of a 
Prior Authorization API. An API is a set of rules or protocols defining 
how requests for data should be made and responses should be returned 
that enables different software applications to communicate and 
exchange data with each other, and a Prior Authorization API is an API 
used to electronically transmit and receive health information related 
to prior authorizations. Per our proposal, the system resulting from 
the appropriate implementation of the proposed FHIR specifications 
would be known as a ``Prior Authorization API.'' Independently, the 
proposed IGs do not have a functionality; rather they define how to 
implement a Prior Authorization API, which comprises multiple FHIR IGs 
integrated to support the full prior authorization workflow from 
initial coverage inquiry through final authorization decision, in a 
manner that has been standardized for industry interoperability.
    The FHIR standard, US Core IG, and SMART App Launch IG are 
implementation specifications widely used across FHIR APIs for a 
variety of use cases. The CRD, DTR, and PAS IGs work in concert to 
inform, submit, and respond to prior authorization requests. These IGs' 
capabilities and functionality, briefly discussed here for reference, 
are discussed more extensively in section II.A.4.a. of this proposed 
rule. When used to implement a Prior Authorization API, the proposed 
IGs define the format and data content (as those terms are defined in 
45 CFR 162.103) for the relevant transactions.
    The HL7 FHIR standards architecture is built upon a foundational 
base FHIR standard, that is open source and free to use with no 
restrictions, to which health care entities can add specific 
functionalities via modular building blocks that can be assembled into 
a variety of systems and applications, including payer servers, 
provider EHRs, mobile apps, and cloud communications to standardize 
interoperable health data exchange.\276\ FHIR IGs define how FHIR 
capabilities are used in particular data exchanges or to solve 
particular problems, and the other specifications and IGs discussed in 
this section of the proposed rule are all built upon the base FHIR 
standard.

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

    Frequently, health care entities have specific technical 
requirements, for needs such as custom data fields or workflow 
processes, beyond the standard FHIR specifications. For use cases that 
are common across a large segment of the health care industry, those 
added functionalities can be standardized as IGs that effect a common 
solution to those use cases. This add-on approach keeps the base FHIR 
standard manageable while allowing health care entities to tailor 
systems to meet specific operational needs. In the case of prior 
authorization, the CRD, DTR, and PAS IGs are designed using the FHIR 
base standard, but to the specific requirements of their use cases 
within the prior authorization process. As the needs of industry and 
technology evolve, developers and implementers can customize FHIR APIs 
within the strictures of the IGs, and HL7, as the Standards Setting 
Organization (SSO), has greater flexibility to modify FHIR standards 
and IGs.
    The US Core IG is a set of rules that define how data, such as 
patient records, medication, and lab results, are formatted and 
exchanged in the United States.\277\ The IG is built to follow other 
HHS requirements, particularly the US Core Data for Interoperability 
(USCDI), which is an/ONC-maintained set of health data classes and data 
elements for nationwide, interoperable health information exchange 
established under authority independent of HIPAA.\278\ The US Core IG 
is an essential underlying specification for any FHIR implementation 
within the United States that provides basic data structure and 
formatting rules required for FHIR APIs exchanging data elements within 
the USCDI.

    SMART is an open standard that enables health apps to securely 
connect to and interact with EHRs and other health IT systems. The 
SMART App Launch IG is a set of technical implementation specifications 
that define how client health apps can securely authorize, 
authenticate, and integrate with a FHIR-based data

[[Page 19990]]

system.\279\ This standardized approach allows health apps to work 
across different EHRs and other health IT systems without requiring 
custom integration for each system. ``SMART on FHIR'' apps (``SMART 
apps'') that are built using both the SMART and FHIR standards can be 
integrated into existing health IT systems to provide additional 
functionality.

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

    The SMART App Launch IG allows SMART apps to access the FHIR 
server, regardless of the underlying architecture of the client's 
health IT system.\280\ SMART apps function similarly to mobile apps on 
a smartphone--they can be added to existing systems to provide new 
capabilities. These apps are currently used across various EHRs, other 
health IT, and mobile devices. For prior authorization, we expect that 
the primary use case would be health care providers using SMART apps 
(which are enabled by a FHIR API being implemented with SMART App 
Launch IG) within their health IT system to extend that system's 
functionality to interact with Prior Authorization APIs and provide 
additional automation for the prior authorization process, such as 
checking coverage requirements, submitting requests, and tracking 
approval status. SMART apps have been developed to interpret the health 
plan's structured prior authorization requirements from the CRD and DTR 
IGs and to automate the process of collecting documentation.

    The CRD IG is used to define a workflow for health plans to 
transmit information about coverage requirements, such as health plans' 
requirements to request and receive prior authorization, to health care 
providers through their health IT system.\281\ The CRD IG enables 
health care providers to query the Prior Authorization APIs to 
determine whether prior authorization is required, and also provides 
information about a health plans' prior authorization coverage rules so 
a health care provider knows what is necessary to support its prior 
authorization request to obtain authorization for health care for a 
patient.

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

    The CRD IG is designed solely for prior authorization use cases, 
not any other type of eligibility or benefit information, so prior 
authorization-related transmissions are the sole use case for which we 
propose to modify the X12N 270/271 transaction standard adopted in 45 
CFR 162.1202. Therefore, our proposal for the ``eligibility for a 
health plan'' transaction is limited to those where the CRD IG can be 
used, that is, for transmissions related to prior authorization (as we 
propose to define that term in 45 CFR 162.103) to determine whether 
prior authorization is required. We propose no changes to ``eligibility 
for a health plan'' transactions described in 45 CFR 162.1202 unrelated 
to prior authorization, for which the standard transactions would 
continue to be the adopted X12N 270/271 transaction standard.
    The DTR IG specifies how a health plan's documentation requirements 
for prior authorization requests are communicated to a health care 
provider,\282\ streamlining prior authorization and documentation by 
enabling payers to send interactive, automated forms known as FHIR 
Questionnaires and rules directly into a provider's EHR. Typically 
triggered by an automated CRD IG check, health plans use the DTR IG to 
code prior authorization documentation requirements, which, for 
example, could apprise health care providers that a prior authorization 
approval requires particular test results or that they would need to 
fill out a certain form with patient medical history. The DTR IG can 
automate the assembly of documentation to support a prior authorization 
request, enabling health care providers to download FHIR questionnaires 
from the health plan (for example, structured forms or templates that 
health plans use to collect specific clinical information needed to 
evaluate whether a requested service meets coverage criteria and 
medical necessity requirements). EHRs, other health IT systems, or 
SMART apps could use that information to automatically populate the 
required test results and patient history to transmit to the health 
plan.

    The PAS IG, used when a health care provider submits a prior 
authorization request and required documentation to a health plan, 
enables a prior authorization request to be transmitted via FHIR API 
from a health care provider's EHR or other health IT system and a 
health plan to notify a provider of its decision.\283\ The PAS IG also 
defines capabilities for managing prior authorization requests, 
including checking the status of a previously submitted request, 
updating a previously submitted request, and canceling a request.

4. Reports and Recommendations
    On April 20, 2021, the Secretary approved exceptions requested by 
the HL7 Da Vinci Project to test FHIR standards.\284\ The exceptions 
covered the two adopted transactions discussed previously related to 
prior authorization: (1) dental, professional, and institutional 
``referral certification and authorization'' transactions; and (2) the 
``eligibility for health plan'' transactions when used to determine 
whether prior authorization is required.\285\ Like our current 
proposals, these exceptions only applied to ``eligibility for a health 
plan'' transactions used to determine whether prior authorization is 
required, not the full scope of ``eligibility for a health plan'' 
transactions described in 45 CFR 162.1202. After a year of testing, on 
June 25, 2024, the HL7 Da Vinci Project submitted to HHS its required 
report on the test results,\286\ including the required cost-benefit 
analysis, which is discussed later in this section. On April 29, 2025, 
the Secretary issued a Federal Register notice regarding the 
availability of the HL7 Da Vinci Project's report on an HHS website (90 
FR 17827).

    The Health Information Technology Advisory Committee (HITAC) is a 
Federal Advisory Committee established by section 3002 of the PHSA, as 
amended by the 21st Century Cures Act (hereinafter referred to as the 
``Cures Act'') (Pub. L. 114-255, enacted December 13, 2016). HITAC 
offers recommendations to ONC on health IT policies, standards, 
implementation specifications, and certification criteria

[[Page 19991]]

relating to the implementation of a health IT infrastructure that 
advances electronic access, exchange, and use of health information. In 
2020, ONC charged HITAC to establish a task force, that became known as 
the Intersection of Clinical and Administrative Data Task Force (ICAD), 
to consider the convergence of clinical and administrative data and 
make recommendations to HITAC. In what resulted in a November 2020 
report to ONC, HITAC and NCVHS joined forces in ICAD's effort to 
support the convergence of clinical and administrative data and improve 
data interoperability across the ecosystem to enhance patient access 
and improve health care efficiency.287 288

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

    ICAD's report stated that one of the primary factors contributing 
to the X12N 278 transaction standard's low adoption is the transaction 
set's lack of specificity and flexibility.\289\ FHIR's flexibility can, 
we believe, address those shortcomings and we identify three specific 
attributes: (1) the FHIR standard and associated specifications were 
developed using a consensus-based process to capture requirements 
across health care settings; (2) the quality of data that can be 
exchanged using the FHIR standards is greater than can be exchanged 
with other standards, including the X12N 278 transaction standard; and 
(3) a FHIR API's architecture allows the exchange of more types and a 
greater quantity of data. ICAD and the NCVHS also identified the lack 
of an attachment standard for prior authorizations as a factor 
contributing to low adoption. We had proposed, but elected not to 
finalize, the X12N 275 attachment standard for prior authorization 
transactions in the 2022 HIPAA Standards for Health Care Attachments 
proposed rule, ultimately finalizing the more limited 2026 HIPAA 
Standards for Health Care Attachments final rule and electing to later 
proceed with this proposal to adopt the HL7 Da Vinci Clinical Data 
Exchange (CDex) IG, as the HIPAA standard for attachments to prior 
authorization transactions.\290\

    On July 28, 2022, the NCVHS sent HHS a recommendation letter to 
``support the transformative changes occurring in health care delivery 
systems, payment methodologies, standards development, and rule 
adoption.'' \291\ That letter's recommendations were based on an NCVHS 
listening session held on June 9, 2022 and letters of public comment 
from the ``National Committee on Vital and Health Statistics: Notice of 
Meeting and Request for Public Comment'' (86 FR 
33318).292 293 The NCVHS also cited the HITAC/ICAD report as 
originating its vision.\294\ In that letter, the NCVHS stated that 
support for API technology, including the FHIR standard, could be more 
effective and efficient than certain current adopted transaction 
standards. The NCVHS stated that the advantages of FHIR standards for 
some stakeholders could include better workforce availability, lower 
total labor costs, or technical compatibility. We agree with the 
NCVHS's analysis that adopting FHIR standards could benefit the 
industry by providing needed flexibility to address the wide range of 
business processes that HIPAA covered entities use to request prior 
authorization and make and communicate prior authorization decisions. 
The NCVHS highlighted a quote from the listening session that costs and 
benefits should be looked at holistically, and, though organizations 
would have upfront FHIR implementation costs, the benefit of a smoother 
experience and faster process outweighs the cost.

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

    In that letter, the NCVHS also recommended that HHS adopt multiple 
standards for each transaction to co-exist for specific business needs. 
Specifically, they suggested that we allow some HIPAA covered entities 
to use FHIR standards while others could use the extant X12N 
transaction standard, as doing so would allow various standards to be 
tested and used for specific business needs. Notably, we agree only in 
part with that recommendation. We understand that the same standards 
may not meet the needs of every use case and segment of the health care 
industry, which, for example, is why we have adopted different 
standards, developed by NCPDP, for retail pharmacies across many of the 
standard transactions. Similarly, for the ``health claims or equivalent 
encounter information'' transaction, we have adopted, in 45 CFR 
162.1102, different standards for four types of claims: retail pharmacy 
drugs, dental health care, professional health care, and institutional 
health care. With these proposals, we continue to make those 
distinctions, as section 1173(a)(3) of the Act requires the Secretary 
to accommodate the needs of different types of health care providers.
    However, we disagree that the industry would benefit from our 
indefinitely adopting multiple standards for the same types of 
transactions. Section 1172(b) of the Act requires that any standard 
adopted by the Secretary be consistent with HIPAA Administrative 
Simplification's objective of reducing the administrative costs of 
providing and paying for health care. We have incorporated reasonable 
transition periods into certain HIPAA rulemaking,\295\ but believe that 
adopting in perpetuity multiple overlapping standards would contravene 
the statutory purpose by potentially requiring that HIPAA covered 
entities support both the X12N and FHIR standards, which could increase 
the health care system's administrative burden and costs.
---------------------------------------------------------------------------

    \295\ See, for example, 89 FR 100763 (Version D.0/Version 1.2 to 
Version F6/Version 15 8 months transition period).
---------------------------------------------------------------------------

    Furthermore, the NCVHS sent its recommendation letter before the 
HL7 Da Vinci Project's exceptions testing concluded and its report was 
published. The NCVHS' July 28, 2022 letter to HHS included a 
recommendation to allow

[[Page 19992]]

stakeholders to test, evaluate, and plan for modified standards; the 
HL7 Da Vinci Project's report offers the results of just that sort of 
real-world testing and demonstrates the FHIR standards' benefits. The 
exceptions testing report, which fulfilled several NCVHS 
recommendations, was a natural sequent to the recommendations and 
evidenced many of the NCVHS's points that a modified and modernized 
standard could benefit the industry and should be considered by HHS for 
adoption.
    After the April 20, 2021, HIPAA exceptions approval, but before the 
June 25, 2024 testing report, and in accordance with separate 
rulemaking and legal authority, CMS proposed and later finalized its 
2024 CMS Interoperability and Prior Authorization final rule (87 FR 
76238, 89 FR 8869). There, CMS finalized a requirement that ``impacted 
payers'' implement and maintain a Prior Authorization API, requiring 
impacted payers to use a version of the base FHIR standard adopted in 
45 CFR 170.215(a)(1), a version of the US Core IG adopted in 45 CFR 
170.215(b)(1)(i), and a version of the SMART App Launch IG adopted in 
45 CFR 170.215(c)(1) (89 FR 8945). CMS also recommended that impacted 
payers use the CRD, DTR, and PAS IGs that were at the time being tested 
by the HL7 Da Vinci Project under the approved exceptions (89 FR 
8945).\296\ Those standards which we propose to adopt in this HIPAA 
rulemaking section, are described further in section II.A. of this 
proposed rule, along with CMS's proposals to require impacted payers to 
use updated versions of the previously recommended IGs.
---------------------------------------------------------------------------

    \296\ CMS explained that the approach of recommending, but not 
requiring, the specific IGs and versions provided directional 
guidance with flexibility to the industry in order to allow for 
additional improvements to be made without locking implementers into 
versions of the IGs available at the time of the proposed rule. (89 
FR 8938)
---------------------------------------------------------------------------

    In response to public comments received on multiple notices of 
proposed rulemaking and extensive stakeholder outreach to HHS, 
including regular interim discussions with the HL7 Da Vinci Project 
about the status of its exceptions testing, we issued a notice of 
enforcement discretion on February 28, 2024.\297\ That notice stated 
that we would not take administrative simplification enforcement action 
against HIPAA covered entities that elected not to use the X12N 278 
transaction standard but instead used the FHIR standards for prior 
authorization transactions. We also stated that we would continue to 
evaluate the HIPAA prior authorization transaction standards. In part 
as a result of that analysis, we did not finalize in the 2026 HIPAA 
Standards for Health Care Attachments final rule the X12N-based prior 
authorization attachment requirements we had previously proposed, and, 
instead, now make these proposals.

5. Benefits of Setting Prior Authorization on FHIR
    The adopted X12N 278 transaction standard has a low implementation 
rate among health plans. According to the Council for Affordable 
Quality Healthcare (CAQH), as of 2024 just 35 percent of medical plans 
have adopted the electronic standard, while 43 percent use a payer-
specific portal and 22 percent rely on manual processes, such as phone, 
email, or fax.\298\ Health plan adoption of the other adopted HIPAA 
standards ranges from 77 percent to 100 percent, so the X12N 278 
transaction standard's aberrantly low industry adoption rate suggests 
there may be a problem, which may be that it does not meet many HIPAA 
covered entities needs.\299\

https://www.caqh.org/hubfs/Index/2024%20Index%20Report/CAQH_IndexReport_2024_FINAL.pdf.
    \299\ The CAQH also identified low adoption of the available 
standard supporting health care claims attachments, for which a 
standard had been proposed in the 2022 HIPAA Standards for Health 
Care Attachments proposed rule (the X12N 275 transaction standard), 
but not finalized in the 2026 HIPAA Standards for Health Care 
Attachments final rule which appears elsewhere in this issue of the 
Federal Register. See the proposal at https://www.federalregister.gov/d/2022-27437/p-141 and the CDex IG proposal 
in subsequent pages of this section.
---------------------------------------------------------------------------

    Multiple sources report that health care providers find prior 
authorization to be their most burdensome administrative transaction. 
The AMA reports that physicians and their staff spend an average of 13 
hours each week completing prior authorization requests and 40 percent 
have staff who work exclusively on prior authorizations.\300\ The 
proposed modification to the standard transactions would not entirely 
alleviate that burden, but analyses indicate that our adoption of the 
FHIR standards could significantly reduce health care provider and 
staff time spent on prior authorizations. According to the 2024 CAQH 
Index Report, providers reported that it took, on average, 24 minutes 
to request an authorization from a health plan using manual processes 
and 16 minutes using a health plan portal,\301\ while conducting the 
X12N 278 transaction standard as a fully electronic process reduced the 
time it took providers to 10 minutes on average. But, based on its 
testing the HL7 Da Vinci Project reported that a FHIR-based transaction 
reduced the time required to perform the necessary activities to 
request a prior authorization to 5 to 6 minutes per transaction on 
average,\302\ thus amounting to a 40-60% time savings that clinicians 
could potentially rededicate to patients as opposed to bureaucracy! 
That decrease was primarily due to receiving real-time feedback as part 
of the clinical workflow within an EHR or other health IT.

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

    Unlike other existing standards that utilize point-to-point EDI, 
such as X12N transaction standards, the Prior Authorization API's real-
time and interactive nature would allow health care providers to use 
their EHRs or other health IT to automate processes such as 
documentation collection and to receive real-time feedback on missing 
information or errors. Historically, EDI, like the X12N 278 transaction 
standard, has generally relied on batch-processing using standardized 
document formats to asynchronously exchange data; by contrast, APIs' 
web-based technology enables real-time synchronous data exchange using 
flexible formats that can offer faster implementation, near-
instantaneous results, and lower costs.
    While EDI remains the standard for many established administrative 
transactions, HHS believes that APIs such as the FHIR API may represent 
the future direction of health data exchange. Unlike EDI and most of 
the current adopted HIPAA standards that rely on narrow and granularly 
specified transmissions, transactions using APIs may consist of many 
interactions and data exchanges between the server and client systems. 
Regardless of the inner workings of the API and data exchange, for the 
purposes of HIPAA rulemaking,

[[Page 19993]]

we consider the entire process of requesting prior authorization and 
receiving a decision--including any intermediate steps--to comprise the 
transaction for which we are proposing to adopt the FHIR standard and 
applicable FHIR IGs as the HIPAA standard.
    The 2024 AMA Prior Authorization Physician Survey revealed that 61 
percent of physicians reported that it was difficult to determine 
whether prior authorization was required for medical services, and 
thirty percent of physicians reported that prior authorization 
information in their EHR was rarely or never accurate.\303\ Our 
understanding is that prior authorization requirements available 
through EHRs or other health IT today are generally static lists that 
must be continually updated or the information available may become 
out-of-date. By contrast, interactions with a Prior Authorization API 
could be integrated into health care providers' clinical workflows 
through their health IT system, enabling them to directly query a 
health plan as to whether prior authorization would be required while 
discussing treatment with a patient, rather than performing such a 
check later. The HL7 Da Vinci Project's testing revealed that providers 
immediately received a health plan response in their EHR when using the 
CRD IG to query whether prior authorization was required, and that 84 
percent of those immediate responses apprised them that services or 
treatments did not require prior authorization.\304\ That immediacy 
could contribute to the proposed FHIR standards biggest operational 
efficiency gains and enable health care providers to focus on patient 
care as opposed to wasting significant time and effort submitting a 
prior authorization request that, in the majority of instances, was 
unnecessary.

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

    By contrast, the current X12N 278 transaction standard generally is 
not executed in real time. Though it is capable of being exchanged in 
real time as CAQH Core operating rules do allow that, our 
understanding, informed by industry and SSO feedback, is that those 
real-time operating rules, which have not been adopted under HIPAA, are 
rarely if ever implemented and used.\305\ The time to simply determine 
whether prior authorization is required could delay treatment in 
instances when prior authorization is not even required.
---------------------------------------------------------------------------

    \305\ Those operating rules are available at https://www.caqh.org/core/operating-rules.
---------------------------------------------------------------------------

    Similarly, we believe that HIPAA covered entities' use of FHIR, and 
specifically the CRD IG for the ``eligibility for health plan'' 
transaction, could decrease the number of requests for prior 
authorization that a health plan would have to process, only to 
determine that prior authorization was not required. We believe that 
dynamic was, for example, reflected in a comparison, during the 
exceptions testing, of the number of prior authorization requests that 
were voided by the health plan or health care provider because they 
were duplicates, were cancelled, or had data issues. The HL7 Da Vinci 
Project reported that 20 percent of requests were voided using the FHIR 
standards while 45 percent of requests were voided using a payer's 
portal with the integrated X12N 278 transaction standard.\306\ Both 
methods had 8 percent of requests denied and 1 percent partially 
approved. The 25 percent difference in voided requests directly 
correlates to the number of requests fully approved--71 percent with 
FHIR and 46 percent with a direct data entry portal and the X12N 278 
transaction standard. These data suggest that a significant percentage 
of X12N 278 transaction standard requests that were ultimately approved 
were first voided because of data issues or procedural problems with 
the request. Unnecessary requests often impose excessive and 
unwarranted burdens on HIPAA covered entities that we believe could be 
avoided with the more flexible, interactive, and real-time FHIR 
standards we are proposing.

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

    The HL7 Da Vinci Project's testing also showed that the Prior 
Authorization API significantly reduced the time it took for health 
plans to communicate prior authorization decisions, which difference 
was demonstrated both with respect to decisions that could be automated 
and those that required human review. For example, 75 percent of prior 
authorization requests for Endometrial Ablation using a health plan's 
portal and the X12N 278 transaction standard were approved within 5 
days; that time decreased to just 5 minutes when using FHIR.\307\ 
Similarly, testing demonstrated that 90 percent of requests for 
Intensity Modulated Radiation Therapy of the thorax, abdomen, and 
pelvis were approved within 49 days using a portal, which decreased to 
11 days using a Prior Authorization API. The HL7 Da Vinci Project's 
testing exceptions report attributed the quicker decisions to the FHIR 
standards' capability to codify documentation policies for automated 
extraction from an EHR. One of the testing participants highlighted 
that the FHIR standard enabled discrete data sharing without the need 
for attachments and enabled the ability to automate workflows to 
display prior authorization results in provider portals for 
transparency.

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

    Therefore, we believe that adopting the FHIR standard and certain 
FHIR IGs as the HIPAA standards for ``referral certification and 
authorization'' transactions and prior authorization-related 
``eligibility for health plan'' transactions could significantly reduce 
costs and burden on patients, health care providers, health plans, and, 
more generally, any HIPAA covered entity involved in the prior 
authorization process. Reducing burden and costs would directly 
effectuate HIPAA Administrative Simplification's explicit aims: 
improving Medicare, Medicaid, and the efficiency and effectiveness of 
the health care system and reducing clinical burden on patients, health 
care providers, and health plans by establishing uniform standards for 
the electronic transmission of certain health information.\308\

    In summary, HHS requests comment on its proposals summarized in 
section II.H.10. of this proposed rule, which includes the proposals 
discussed above, and the CFR citations listed in Table 11.
6. Proposed Modifications and Subsequent Maintenance
    Each proposed specification constantly evolves as new technologies 
and use cases emerge, enhancements are requested by industry, and 
errors are corrected. We specifically propose to adopt for dental, 
professional, and institutional ``referral certification and 
authorization'' transactions related to

[[Page 19994]]

prior authorization, in 45 CFR 162.1302(g)(2), the following versions 
of the standards, which are the same versions that ONC separately 
proposes to be adopted and that CMS proposes be required for impacted 
payers in other sections of this rulemaking:
     The HL7 FHIR Standard, Release 4.0.1;
     US Core IG, Standard for Trial Use (STU) 6.1.0;
     SMART App Launch IG, Release 2.0.0;
     CRD IG, Version 2.2.1--STU 2.2;
     DTR IG, Version 2.2.0--STU 2.2; and
     PAS IG, Version 2.2.1--STU 2.2.
    In addition, in a new 45 CFR 162.1202(f)(2)(i), we propose to adopt 
the following specification versions as the standards for ``eligibility 
for a health plan'' transactions for dental, professional, and 
institutional health care eligibility inquiry and response, when used 
to determine whether prior authorization is required:
     The HL7 FHIR Standard, Release 4.0.1;
     US Core IG, STU 6.1.0;
     SMART App Launch IG, Release 2.0.0; and
     CRD IG, Version 2.2.1--STU 2.2.
    We encourage all interested parties to engage with the standards 
development process to best ensure the standards reflect input from 
across the health care industry, and acknowledge that the versions of 
the proposed standards may be updated in the period between publication 
of this proposed rule and any final rulemaking (should we finalize this 
rule) pursuant to updates in the normal course as a result of the SSO's 
consensus-based process. We request public comment on whether we should 
adopt an updated version of any proposed standard, should such become 
available by the time of final rulemaking. Doing so would allow us to 
adopt, and HIPAA covered entities to use, the latest and most up-to-
date versions of the standards available at the time of a final rule 
rather than locking in versions specified in this proposed rule. Newer 
versions would include consensus-based updates made through the SSO's 
development and maintenance process. That could better align the HIPAA 
transaction standards with other HHS initiatives that encourage 
interoperability and efficient information exchange in the health care 
industry.
    While we propose to adopt specific versions of the proposed 
standards, we also look to balance industry desire to be able to use 
later versions of adopted standards once they are finalized by the SSO 
without additional rulemaking. The HIPAA regulatory paradigm envisions 
ongoing maintenance to the adopted standards, as described in 45 CFR 
162.910(b). As defined at 45 CFR 162.103, ``maintenance'' refers to 
activities necessary to support the use of a standard adopted by the 
Secretary, including technical corrections to an implementation 
specification that could be non-substantive or error correction. To 
enable that maintenance, as described in 45 CFR 162.910(a), the 
Secretary may designate an organization that agrees to maintain adopted 
standards. Maintenance, as described in 45 CFR 162.910(b), is a process 
performed by the appropriate DSMO, if done in accordance with the 
processes the Secretary may require. Even with respect to maintenance 
changes, the normal ANSI-accredited standards development process still 
would require public notification and comment, but regulatory action is 
not required. We further describe the standards development and 
maintenance process in the 2022 HIPAA Standards for Health Care 
Attachments proposed rule (87 FR 78440 and 78441).
    The term ``maintenance'' excludes the activities related to the 
adoption of a new standard or implementation specification, or 
modification to an adopted standard or implementation specification. As 
discussed in the ``Health Insurance Reform; Announcement of Maintenance 
Changes to Electronic Data Transaction Standards Adopted Under the 
Health Insurance Portability and Accountability Act'' final rule (65 FR 
50322), which appeared in the Federal Register on October 13, 2010, and 
which referenced the 2000 Standards for Electronic Transactions final 
rule, when a change is substantial enough to justify publication of a 
new version of an implementation specification, such change is 
considered a modification and must be adopted by the Secretary through 
regulation.
    HL7 uses semantic versioning, a standardized numbering system that 
indicates the type and scope of changes made to software 
specifications, with a ``Major.Minor.Patch'' version format where each 
term is represented by an integer (for example, 1.2.3). The ``Major'' 
number is incremented when HL7 publishes a significant new release of 
the FHIR specification. The ``Minor'' number is incremented for updates 
that introduce minor substantive changes, potentially including 
``limited breaking changes,'' which are changes that may affect 
specific optional features or add new required fields while maintaining 
compatibility with previous versions. The ``Patch'' number is 
incremented to indicate an update including only technical corrections 
to a prior release. Patches, we believe, are equivalent to the errata 
to the current adopted standards that, pursuant to maintenance updates, 
are effectuated without rulemaking, and we would consider patches to be 
maintenance updates rather than modifications to the adopted standard. 
The same schema would be applied, as applicable, for all FHIR 
specifications and IGs. For example, the PAS IG has, between 2020 and 
2026, advanced as follows: 2020--version 1.0.0; 2021--version 1.1.0; 
2022--version 1.2.0; 2023--version 2.0.0; 2024--version 2.0.1; 2025--
version 2.1.0; and 2026--version 2.2.1.
    Specifically, that means that if HL7 publishes a version with the 
same major and minor versions as the adopted standard, but indicates 
that technical corrections are included by using a patch version, HIPAA 
covered entities would be permitted to use that updated version as it 
would be considered a maintenance update. Such a framework would allow 
HIPAA covered entities to update their Prior Authorization APIs or 
health IT systems to address identified issues without waiting for 
additional rulemaking. The Secretary would rely on HL7, as the DSMO, 
and its existing versioning system, as an indicator of whether scope 
changes to the adopted standard would be ``technical corrections'' as 
described in the definition of ``maintenance'' in 45 CFR 162.103, or 
would be more substantive modifications requiring rulemaking to adopt. 
For example, this means that if our proposal to adopt the PAS IG, 
Version 2.2.1 were finalized, and HL7 were to subsequently publish PAS 
IG, Version 2.2.2, that later version would be considered a maintenance 
update to the adopted standard, as described in Section 1174 of the Act 
and 45 CFR 162.910. Therefore, HIPAA covered entities would be 
permitted to use the PAS IG, Version 2.2.2 without additional 
rulemaking. However, if a subsequent version of the PAS IG were to be 
published, for example PAS IG, Version 2.3.0, that would indicate to us 
that the changes were substantive enough to require modification via 
rulemaking.
    We believe such a framework would be consistent with the discussion 
of maintenance in 45 CFR 162.910 and, should this proposed rule be 
finalized as proposed, we anticipate relying upon it. However, we also 
request comment on whether versioning is the appropriate indicator on 
which we should rely, or whether we should require other considerations 
or processes.

[[Page 19995]]

    In summary, HHS requests comment on its proposals summarized in 
section II.H.10. of this proposed rule, which includes the proposals 
discussed above, and the CFR citations listed in Table 11.
7. FHIR Standard for Attachments to Prior Authorization Transactions
    In the 2022 HIPAA Standards for Health Care Attachments proposed 
rule, we proposed the X12N 275 transaction standard for ``health care 
attachments'' for certain HIPAA Administrative Simplification 
transactions. Specifically, we proposed the X12N 275--Additional 
Information to Support a Health Care Services Review (06020X316) 
standard to support ``referral certification and authorization'' 
transactions and the X12N 275--Additional Information to Support a 
Health Care Claim or Encounter (06020X314) standard to support ``health 
care claims or equivalent encounter'' transactions (87 FR 78447).
    In response to that proposed rule, many commenters urged us instead 
to adopt the CDex IG,\309\ a FHIR IG, rather than the X12N 275 
attachment standard for prior authorization transactions. The CDex IG 
provides guidance for implementers to support FHIR-based interactions 
for specific clinical data exchanges. In particular, the CDex IG 
supports real-time exchange for both structured and unstructured 
clinical data through FHIR APIs, which can improve efficiency and 
reduce administrative burden. Commenters viewed the CDex IG as a modern 
and flexible solution that supports industry needs and the federal 
government's broader interoperability and administrative simplification 
goals. Commenters reasoned that the CDex IG facilitates exchanging any 
information a health care provider holds in a patient's health record 
as it is not limited to FHIR resources, but includes the ability to 
attach files, such as C-CDA documents, PDFs, text files, and other 
formats. Commenters added that the flexibility to include a variety of 
file types is particularly relevant to prior authorization 
documentation requirements as contrasted with the types of attachments 
that typically are necessary to submit claims. The CDex IG supports 
FHIR-based communication between health plans and health care 
providers, allowing documentation and attachments to be shared more 
seamlessly across health IT systems.
---------------------------------------------------------------------------

    \309\ Health Level Seven International. (n.d.). Da Vinci 
Clinical Data Exchange (CDex) IG. Retrieved from https://hl7.org/fhir/us/davinci-cdex/.
---------------------------------------------------------------------------

    Commenters raised numerous points, including that: (1) the CDex IG 
allows health plans to be explicit about the data they are requesting, 
which would prevent health care providers from having to spend time 
gathering and sending more information than necessary; (2) the CDex IG 
would complement the FHIR standards finalized in the 2024 CMS 
Interoperability and Prior Authorization final rule, and harmonizing 
standards would promote consistent, scalable, and flexible data 
exchange (89 FR 8864 and 8941); (3) adopting the CDex IG would enable 
faster, automated determinations of medical necessity, and could 
eliminate redundant manual steps by allowing health plans to request 
and receive clinical data directly; (4) this approach would integrate 
with existing prior authorization workflows and would support 
information exchanges needed to make coverage determinations; and (5) 
many prior authorizations require additional documentation, and that 
even with the X12N 275 attachment standard, obtaining this information 
would be burdensome for health care providers and health plans.
    Similarly, in response to the 2024 CMS Interoperability and Prior 
Authorization final rule, which did not propose to require impacted 
payers to implement an attachment standard, multiple commenters urged 
CMS to formally recommend the CDex IG (as it did with other IGs) in the 
final rule and stated that it is a critical part of burden reduction 
and plays an important role in supporting FHIR prior authorization 
transactions (89 FR 8864). CMS declined to do so, but encouraged 
impacted payers to participate in ongoing testing and stated that it 
would consider requiring or recommending CDex IG in future rulemaking 
(89 FR 8941).
    After considering the significant and persuasive public comments in 
opposition, we did not finalize the proposed attachment standard for 
``referral certification and authorization'' transactions in the 2026 
HIPAA Standards for Health Care Attachments final rule. We declined to 
finalize those provisions in part because the proposed X12N 275 
attachment standard would not align with the 2024 CMS Interoperability 
and Prior Authorization final rule published in the Federal Register on 
January 17, 2024 (89 FR 8758). As described previously, the FHIR 
standard permits more granular data to be transmitted, obviating in 
many instances the need for an additional attachment standard. However, 
even should our proposal to adopt FHIR be finalized as proposed we 
understand that some prior authorization use cases still would require 
an attachment. Therefore, we believe that HIPAA covered entities could 
benefit from using the CDex IG for prior authorization attachments, and 
propose to adopt the CDex IG, Version 2.1.0--STU 2.1, in 45 CFR 
162.1302(g)(2)(vii) as the standard for attachments to prior 
authorization transactions. We are not proposing at this time to adopt 
the CDex IG for any transaction other than prior authorizations because 
that is the only HIPAA Administrative Simplification transaction for 
which we are proposing to adopt FHIR standards.
    Because the Da Vinci Project did not include the CDex IG in its 
testing exception, we continue to evaluate the CDex IG's maturity for 
adoption in HIPAA Administrative Simplification standard for 
attachments to prior authorization transactions. In its July 28, 2022 
recommendation letter, NCVHS noted HL7 FHIR could be more effective and 
efficient for certain HIPAA transactions. NCVHS recommended that HHS 
not disrupt HIPAA transactions that are working well using the current 
adopted standards, but that standards that are not well adopted or 
utilized by industry--namely prior authorization or attachments--could 
be instances where FHIR ``provides an on-ramp for a new generation of 
standards.'' \310\ At the December 2025 listening session, we asked the 
named consultative organizations and DSMOs to comment on the maturity 
of the CDex IG and whether it is adequately mature for us to propose as 
the attachments standard for prior authorization transactions.\311\ 
Multiple organizations reported both in that session and in follow-up 
letters that the CDex IG would be the appropriate attachment standard 
for any transactions using FHIR, and urged us to propose to adopt the 
CDex IG for attachments to prior authorization transactions.

    In summary, HHS requests comment on its proposals summarized in 
section II.H.10. of this proposed rule, which includes the proposals 
discussed above, and the CFR citations listed in Table 11.

[[Page 19996]]

8. Compliance Date
    HHS proposes, in 45 CFR 162.1202(e) and 45 CFR 162.1302(f), that 
HIPAA covered entities would be required to comply with the proposed 
modified standard no later than 24 months from the effective date of a 
final rule, except for small health plans,\312\ for which the 
compliance date would be 36 months from the effective date of a final 
rule.
---------------------------------------------------------------------------

    \312\ As defined in 45 CFR 160.103, small health plans are those 
with annual receipts of $5 million or less.
---------------------------------------------------------------------------

    Section 1175(b)(2) of the Act specifies that the compliance date 
for a modification to a standard or implementation specification cannot 
be sooner than 180 days after the date the modification is adopted. A 
modification is ``adopted'' on the date it becomes effective, which 
here would be 60 days after its publication in the Federal Register. 
Although these proposals would constitute modifications to an existing 
standard, as described in section 1174(b) of the Act, the modifications 
would represent a significant departure from the currently adopted 
standard. We expect that most HIPAA covered entities would, by virtue 
of other requirements, be familiar with the proposed FHIR standards by 
2027. In the 2024 CMS Interoperability and Prior Authorization final 
rule, CMS provided approximately 3 years between its February 2024 
Federal Register publication and the 2027 compliance dates (89 FR 
8758). There, CMS stated that commenters expressed that impacted payers 
would need between 18 and 36 months to implement the interoperability 
APIs finalized in that rule (89 FR 8763).
    In addition to the Prior Authorization API, CMS finalized in the 
2024 CMS Interoperability and Prior Authorization final rule 
requirements for impacted payers to implement and maintain Provider 
Access and Payer-to-Payer APIs, as well as requirements to modify their 
Patient Access APIs. Thus, the compliance dates proposed in the 2022 
CMS Interoperability and Prior Authorization proposed rule were made 
with consideration of commenters' responses for implementing 
requirements for API development and enhancement. Because the HIPAA 
proposals we make here only include the technical standards that 
support one of the APIs CMS finalized in that rule, we believe it is 
appropriate to propose a shorter compliance timeframe.
    Therefore, we believe it is reasonable to follow the statutory 
timeline for new standards in section 1175(b)(1) of the Act. We propose 
a compliance date 24 months after the modified standard is adopted, 
which would be 60 days after a final rule appears in the Federal 
Register. Aligning with the statutory requirement for initial 
standards, we propose that small health plans would have an additional 
12 months before being required to comply with the modified standards. 
We believe that proposing to provide small health plans an additional 
12 months would be appropriate considering CMS's existing requirements 
for impacted payers. We believe that health insurance companies that do 
not offer health plans as MA organizations, Medicaid MCOs, CHIP managed 
care entities, or QHP issuers on the FFEs would more likely be small 
health plans than the impacted payers. As non-impacted payers, they 
would be less likely to be on the path to implementing a Prior 
Authorization API using these proposed HIPAA transaction standards.
    Therefore, we anticipate that health IT vendors that offer 
implementation support to health care providers and other HIPAA covered 
entities would be familiar with the proposed HIPAA transaction 
standards by 2027. In addition to CMS requirements, ONC has finalized 
certification criteria for electronic prior authorization through the 
ONC Health IT Certification Program in 45 CFR 170.315(g)(31) through 
(33). Those certification criteria are based on the implementation of 
the CRD, DTR, and PAS IGs. While those are criteria aimed at certifying 
health IT used by health care providers, we expect that other 
developers and vendors of systems supporting health plans may gain 
familiarity with the proposed FHIR standards through the requirements 
and resources available through the ONC Health IT Certification 
Program.
    As discussed elsewhere in this proposed rule, pursuant to CMS 
rulemaking, impacted payers are already required to implement and 
maintain a Prior Authorization API using the same standards as proposed 
here, under HIPAA.\313\ CMS established 2027 compliance dates for 
impacted payers. Most large health insurance companies across the 
country offer health plans as MA organizations, Medicaid MCOs, CHIP 
managed care entities, or QHP issuers on the FFEs. We expect that as 
impacted payers, most non-small plans will have experience implementing 
a Prior Authorization API no later than 2027. In addition, in the HTI-4 
final rule, the Secretary adopted the CRD, DTR, and PAS IGs and ONC 
finalized associated certification criteria for the ONC Health IT 
Certification Program (90 FR 37167). Therefore, we anticipate that 
health IT vendors that offer implementation support to health plans, 
health care providers, and other HIPAA covered entities would be 
familiar with the proposed HIPAA transaction standards by 2027.
---------------------------------------------------------------------------

    \313\ See 42 CFR 422.122(b) for MA organizations, 42 CFR 
431.80(b) for state Medicaid FFS programs, 42 CFR 457.732(b) for 
state CHIP FFS programs, through cross reference to 42 CFR 431.80(b) 
in 42 CFR 438.242(b)(7) for Medicaid managed care plans, through 
cross reference to 42 CFR 438.242 in 432 CFR 457.1233(d) for CHIP 
managed care entities, and 45 CFR 156.223(b) for QHP issuers on the 
FFEs.
---------------------------------------------------------------------------

    We believe that many HIPAA covered entities would not want to 
maintain both methods of electronic prior authorization, using the X12N 
transaction standards and the FHIR standards, until the compliance 
date. We anticipate that the enforcement discretion we announced on 
February 28, 2024, would be effective through the proposed compliance 
dates,\314\ under which HIPAA covered entities, as agreed to by trading 
partners, could use either standard from the effective date of a final 
rule until the compliance dates.

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

    In summary, HHS requests comment on its proposals summarized in 
section II.H.10. of this proposed rule, which includes the proposals 
discussed above, and the CFR citations listed in Table 11.
9. Statutory Authority
    These proposals are made under the authority of Title XI, Part C--
Administrative Simplification, of the Act. Section 1172(b) of the Act 
requires that any standard adopted be consistent with the objective of 
reducing the administrative costs of providing and paying for health 
care. As discussed previously, we analyzed costs for the current X12N 
270/271 and X12N 278 transaction standards, as well as the proposed 
FHIR standards. While the present X12N transaction standards provide 
significant savings versus manual or partially electronic methods of 
exchanging prior authorization information, evidence shows that the 
proposed FHIR standards would further reduce administrative costs for 
health care plans and health care providers. We do not meaningfully 
address clearinghouses in this proposed rule because we do not believe 
they play a significant role in prior authorization transactions, that 
we understand are typically made directly between health care providers 
and health plans, and as contrasted with clearinghouses' significant 
roles with many other

[[Page 19997]]

HIPAA transactions. Nothing, however, would preclude the use of health 
care clearinghouses with respect to the proposed standards.
    Using the proposed FHIR standards could significantly reduce health 
care providers' burden and costs by allowing them to streamline the 
prior authorization processes within their clinical workflow. Health 
care providers might require fewer administrative staff and be able to 
devote more time and resources to patient care. Similarly, by receiving 
requests in the comprehensive and flexible FHIR format, we believe that 
health plans could find efficiencies in their prior authorization 
processes, including that by receiving fewer unnecessary requests, more 
complete documentation, and real-time transactions health plans likely 
could reduce administrative costs. In addition, because CMS's 
interoperability rulemaking already requires impacted payers to 
implement and maintain a Prior Authorization API that meets the 
proposed HIPAA transaction standards, moving away from the present X12N 
transaction standards would allow them to reduce duplicative systems.
    Section 1172(c)(1) of the Act requires adopted standards to be 
developed, adopted, or modified by an SSO. Section 1171(8) of the Act 
and 45 CFR 160.103 define an SSO as an organization that is accredited 
by ANSI that develops standards for information transactions, data 
elements, or any other standard that is necessary to, or will 
facilitate, the implementation of Part C (Administrative 
Simplification) of Title XI of the Act. HL7 is an ANSI-accredited SSO 
that meets these requirements, as demonstrated when HHS named it a DSMO 
as described in 45 CFR 162.910 (65 FR 50373).315 316

    On December 10, 2025, HHS organized a listening session with the 
four organizations named in section 1172(c)(3)(B) of the Act and the 
six DSMOs (some of which are both) regarding the use of a FHIR standard 
for prior authorization transactions.\317\ HHS invited each 
organization to present remarks as well as to submit written materials 
to meet the consultation requirements in section 1172(c)(3)(A) of the 
Act. Those organizations were asked to opine on the impact, benefits, 
and costs of adopting FHIR as the HIPAA transaction standard for those 
transactions. In addition, we asked for feedback on whether adopting 
FHIR would reduce portal usage, how to manage version updates, and 
feedback on the CDex IG for attachments. During that session we heard 
from each organization, and their feedback has been incorporated into 
the discussion of the proposals in this section.

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

    Section 1172(d) of the Act requires the Secretary to establish 
specifications for implementing each of the adopted standards. As 
discussed previously, the proposed specifications are: (1) the base 
FHIR standard; (2) US Core IG, (3) SMART App Launch IG; (4) CRD IG; (5) 
DTR IG; and (6) PAS IG. Section 1172(e) of the Act requires that a 
standard adopted under this part shall not require disclosure of trade 
secrets or confidential commercial information by a person required to 
comply with this part. We do not believe anything in this proposed rule 
would require parties to disclose trade secrets or confidential 
commercial information.
    Section 1172(f) of the Act requires the Secretary to rely on the 
recommendations of the NCVHS, appropriate federal and state agencies, 
and private organizations, and provides that the Secretary shall 
publish in the Federal Register any NCVHS recommendation regarding the 
adoption of a standard. Section 1172(c)(3) of the Act provides that the 
Secretary may not adopt a standard that has been developed, adopted, or 
modified by an SSO unless the SSO consulted with four named 
organizations: the National Uniform Billing Committee (NUBC), the 
National Uniform Claim Committee (NUCC), the Workgroup for Electronic 
Data Interchange (WEDI), and the American Dental Association (ADA). As 
discussed previously, we relied on the NCVHS's July 28, 2022 
recommendation letter to HHS to develop these HIPAA transaction 
standard proposals. The ADA, one of the named organizations in the 
statute, stated that the X12N transaction standards are not working for 
dentistry, and that FHIR-based solutions should be developed and 
replace the HIPAA transactions for dentistry. In addition to the ADA, 
NUCC and WEDI, organizations named for consultation in section 1172 of 
the Act, submitted comment letters in response to the NCVHS's Request 
for Public Comment, which we have also reviewed.
    Section 1173(a)(4)(A) of the Act requires that the standards: (1) 
to the extent feasible and appropriate, enable determination of an 
individual's eligibility and financial responsibility for specific 
services prior to or at the point of care; (2) be comprehensive, 
requiring minimal augmentation by paper or other communications; (3) 
provide for timely acknowledgment, response, and status reporting that 
supports a transparent claims and denial management process; and (4) 
describe all data elements in unambiguous terms, require that such data 
elements be required or conditioned upon set terms in other fields, and 
generally prohibit additional conditions (except where necessary to 
implement state or federal law, or to protect against fraud and abuse). 
In addition, section 1173(a)(4)(B) of the Act requires that, in 
adopting standards and operating rules for transactions referred to 
under paragraph (1), the Secretary seeks to reduce the number and 
complexity of forms (including paper and electronic forms) and data 
entry required by patients and providers.
    Our proposals to adopt the FHIR standards would directly and 
specifically address and satisfy these requirements. Specifically, the 
CRD IG, which we propose to adopt for ``eligibility for a health plan'' 
transactions related to prior authorizations, could be used at the 
point-of-care to determine an individual's eligibility, coverage, and 
benefits for health care services, which could affect the patient's 
financial responsibility. The real-time nature of these transactions 
could increase the frequency that this information could be determined 
before or at the point-of-care, so that providers could discuss options 
with patients based on their individual coverage and prior 
authorization requirements. The FHIR standards that we propose to adopt 
for ``referral certification and authorization'' transactions would be 
more comprehensive than the current X12N transaction standards adopted 
in 45 CFR 162.1302, and could provide more timely acknowledgment, 
response, and status reporting for prior authorizations which could 
support a more transparent claims and denial management process. In 
addition, as discussed previously, based on the HIPAA exceptions 
testing, the FHIR standards have demonstrated that they require minimal 
augmentation by paper or other communications and reduce

[[Page 19998]]

clerical burden on patients and providers.
    Section 1175(b)(2) of the Act requires the Secretary, when adopting 
a modification to a standard, to set an appropriate compliance date, 
considering the time needed to comply due to the nature and extent of 
the modification. That compliance date may not be less than 180 days 
from the date the modification is adopted. In addition, the Secretary 
may extend the time for compliance for small health plans, if 
appropriate. As discussed previously, we propose a 24-month interval 
between adoption and compliance, which we believe is an appropriate 
period for HIPAA covered entities to implement the proposed standards. 
In addition, we propose to provide small health plans with an 
additional 12 months.
10. Summary of Standards Proposals for Prior Authorization Related 
Transactions
    In summary, we request comment on our proposals related to prior 
authorization transactions and on the CFR citations listed in Table 11, 
and specifically on the following:
     The proposal to define prior authorization to mean 
transmissions described in 45 CFR 162.1301(a) used by health care 
providers to obtain authorization for health care, and transmissions 
described in 45 CFR 162.1301(c) used by health plans to respond to such 
requests (see section II.H.2. of this proposed rule).
     The alternative proposal to adopt the FHIR standards of 
this proposed rule for all ``referral certification and authorization 
transactions'' described in 45 CFR 162.1301 (see section II.H.2. of 
this proposed rule).
     The proposal to modify the current operating rules that 
are associated with the ``eligibility for a health plan'' transaction 
to exclude prior authorization-related transmissions (see section 
II.H.5. of this proposed rule).
     The proposal to adopt the following FHIR specifications as 
the standard for dental, professional, and institutional ``eligibility 
for a health plan'' transactions for health care eligibility inquiry 
and response, when used to determine whether prior authorization is 
required: HL7 FHIR, Release 4.0.1. US Core IG, STU 6.1.0; SMART App 
Launch IG, Release 2.0.0; CRD IG, Version 2.2.1--STU 2.2 (see section 
II.H.6. of this proposed rule).
     The proposal to adopt the following FHIR specifications as 
the standard for dental, professional, and institutional ``referral 
certification and authorization'' transactions, within the proposed 
definition of prior authorization: HL7 FHIR, Release 4.0.1; US Core IG, 
STU 6.1.0; SMART App Launch IG, Release 2.0.0; and CRD IG, Version 
2.2.1--STU 2.2; DTR IG, Version 2.2.0--STU 2.2; and the PAS IG, Version 
2.2.1--STU 2.2 (see section II.H.6. of this proposed rule).
     The proposal to adopt the CDex IG, Version 2.1.0--STU 2.1 
as the attachments standard for prior authorization transactions (see 
section II.H.7. of this proposed rule).
     The proposal to adopt modified standards for dental, 
professional, and institutional health care eligibility transactions 
when used to determine whether prior authorization is required with a 
compliance date 24 months from the effective date of a final rule, 
except for small health plans, for which the compliance date would be 
36 months from the effective date of a final rule (see section II.H.8. 
of this proposed rule).
     The proposal to adopt modified standards for dental, 
professional, and institutional prior authorization transactions in 45 
CFR 162.1302(f) with a compliance date 24 months from the effective 
date of a final rule, except for small health plans, for which the 
compliance date would be 36 months from the effective date of a final 
rule (see section II.H.8. of this proposed rule).
     The proposal to adopt the proposed standard for 
attachments to prior authorization transactions in 45 CFR 162.1303 with 
a compliance date 24 months from the effective date of a final rule, 
except for small health plans, for which the compliance date would be 
36 months from the effective date of a final rule (see section II.H.8. 
of this proposed rule).
    In addition, HHS requests comment on the following:
     Whether adopting the FHIR standards for prior 
authorization transmissions and retaining the currently adopted X12N 
transaction standards for other referral certification transmission use 
cases would increase burden on HIPAA covered entities to maintain the 
ability to conduct electronic transactions using two different 
standards (see section II.H.2. of this proposed rule).
     Whether there are benefits to maintaining the existing 
X12N 278 transaction standard, currently adopted in 45 CFR 162.1302, 
for referral certification transmissions (see section II.H.2. of this 
proposed rule).
     Should HHS adopt any later versions of the proposed 
standards, including more recent versions that are currently available 
and versions that may become available between the publication of the 
proposed and final rules (see section II.H.6. of this proposed rule)?
     Should HHS rely on the HL7's Major.Minor.Patch approach to 
reflect that updates from the adopted version are maintenance changes 
that do not require additional rulemaking (see section II.H.6. of this 
proposed rule)?
     Rather than adopting the CDex IG, would it be appropriate 
to recommend it at this time to give the industry an opportunity to 
test the CDex IG in real-world applications (see section II.H.7. of 
this proposed rule)?
     Would adopting the CDex IG affect HIPAA covered entities' 
ability to implement the other proposed FHIR standards (without 
attachments) for prior authorization transactions before the proposed 
compliance date, discussed later in this section? Should HHS finalize a 
later compliance date for CDex to phase implementation of these 
proposals (see section II.H.7. of this proposed rule)?
     Conversely, would it be economical for HIPAA covered 
entities to implement the CDex IG at the same time as the proposed 
prior authorization transaction standards (see section II.H.7. of this 
proposed rule)?
11. Requests for Comment
    In the 2000 Standards for Electronic Transactions final rule, we 
finalized an exception, in 45 CFR 162.923(b), that ``direct data 
entry'' methods of transmitting data need only conform to the data 
content, not the format portion, of the standard. Direct data entry is 
the process by which data are directly keyed by a health care provider 
into a health plan's computer. While the 2000 Standards for Electronic 
Transactions final rule refers to a variety of technologies, we 
understand that the vast majority of direct data entry transactions 
take place through health plan portals. As discussed previously, the 
CAQH Index reveals that prior authorization has the lowest adoption of 
fully electronic transactions among health care administrative 
transactions, at 35 percent. Relatedly, prior authorization has the 
highest usage of ``partially electronic'' transactions, which includes 
web portals and interactive voice response systems, in use by 43 
percent of health plans. Because many health plans are not required to 
offer electronic prior authorization, even as manual processes have 
decreased, the usage of partially electronic prior authorization 
transactions has increased at a greater rate than fully electronic 
transactions.

[[Page 19999]]

    Direct data entry portals create a significantly higher burden on 
health care providers than fully electronic transactions. CAQH survey 
data show that providers spend an average of 16 minutes requesting 
prior authorization using a health plan's portal,\318\ while the HL7 Da 
Vinci Project reported, based on its testing, the use of FHIR decreased 
the time required to perform the necessary activities to request a 
prior authorization to 5 to 6 minutes per transaction on average. In 
addition, because health care providers or their staff need to manually 
type information into a portal (hence the direct data entry), errors 
are likely to be more common than using electronic transactions that 
can pull data directly from provider systems. Erroneous data can lead 
to requests for clarification, delays, and additional burden on health 
care plans and health care providers, which can ultimately result in 
worse care for patients.

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

    Provisions for direct data entry were appropriate based on the 
technology available at the time of the 2000 Standards for Electronic 
Transactions final rule, but subsequent technological advancements may 
now make it ripe to revisit that exception. We are not making any 
proposals in this proposed rule, but, instead, seek comment about 
whether and how the exception should be revisited for possible future 
rulemaking. While portal usage is most prevalent for prior 
authorization transactions, the subject of this proposed rule, the 
direct data entry exception applies to all HIPAA Administrative 
Simplification transactions.
    HHS requests comment on the following:
     Should we revisit the direct data entry exception in 45 
CFR 162.923(b) in order to incentivize or require HIPAA covered 
entities to move from portal-based transactions to fully electronic 
transactions using the adopted standards? If so, how should we amend or 
remove the direct data entry exception to achieve that goal?
     Were we to amend or remove the direct data entry 
exception, how would that affect standard transactions other than prior 
authorization?
     Are there benefits to health plan web portals for HIPAA 
covered entities that we have not considered? Specifically, which types 
of HIPAA covered entities? Which types of transactions?
     What would be the burden to HIPAA covered entities of 
amending or removing the direct data entry exception? Specifically, 
which types of HIPAA covered entities? With respect to which types of 
transactions?
     Would amending or removing the direct data entry exception 
lead to greater adoption of electronic transaction standards or would 
it perversely incentivize HIPAA covered entities to move to fully 
manual transactions?
     Are there particular types of HIPAA covered entities that 
would be especially affected, such as small or rural health care 
practices?

BILLING CODE 4150-28-C

J. Adoption of Health Information Technology Standards and 
Incorporation by Reference

1. Overview
    In this section, ONC proposes to adopt standards and implementation 
specifications in 45 CFR 170.215 for interoperability APIs and related 
activities on behalf of HHS under the authority in section 3004 of the 
PHSA (42 U.S.C. 300jj-14). ONC proposes these standards for adoption by 
HHS as part of a nationwide health IT infrastructure that supports 
reducing burden and health care costs and improving patient care. ONC 
proposes to adopt these standards on behalf of HHS in one location 
within the CFR for use within other HHS programs. These proposals 
reflect a unified approach across HHS to adopt standards for 
interoperability API activities. This approach is intended to increase 
alignment across HHS and reduce regulatory burden for interested 
parties subject to program requirements that incorporate these 
standards.
    In this proposed rule, ONC is proposing to adopt updated versions 
of certain standards that the Secretary adopted in the HTI-4 final rule 
for HHS use (90 FR 37162 and 37181). ONC is proposing to adopt these 
updated versions (listed in section II.J.6. of this proposed rule) in 
45 CFR 170.215. If the adoption of these proposed standards is 
finalized, they would be indicated for use by CMS subject to any other 
requirements that are finalized from this proposed rule. In addition to 
these updated versions, ONC is proposing to adopt an additional 
standard in 45 CFR 170.215(k)(3) that supports the exchange of 
attachment information for prior authorization transactions. Summaries 
of the standards that ONC proposes to adopt and subsequently 
incorporate by reference can be found below in section II.J.8. of this 
proposed rule.
2. Adoption of Standards and Implementation Specifications
    The Health Information Technology for Economic and Clinical Health 
Act (hereinafter referred to as the ``HITECH Act''), Title XIII of 
Division A and Title IV of Division B of the ``American Recovery and 
Reinvestment Act of 2009'' (Pub. L. 111-5), was enacted on February 17, 
2009. The HITECH Act amended the PHSA and created ``Title XXX--Health 
Information Technology and Quality'' to improve health care quality, 
safety, and efficiency through the promotion of health IT and exchange 
of EHI. Subsequently, Title IV of the Cures Act amended portions of the 
HITECH Act by modifying or adding certain provisions to the PHSA 
relating to health IT.
    Section 3001 of the PHSA directs the National Coordinator to 
perform duties in a manner consistent with the development of a 
nationwide health IT infrastructure that allows for electronic use and 
exchange of information.
    Section 3004 of the PHSA identifies a process for the adoption of 
health IT standards, implementation specifications, and certification 
criteria, and authorizes the Secretary to adopt such standards, 
implementation specifications, and certification criteria. As specified 
in section 3004(a)(1) of the PHSA, the Secretary is required, in 
consultation with representatives of other relevant federal agencies, 
to jointly review standards, implementation specifications, and 
certification criteria endorsed by the National Coordinator under 
section 3001(c) of the PHSA and subsequently determine whether to 
propose the adoption of any grouping of such standards, implementation 
specifications, or certification criteria. The Secretary is required to 
publish all determinations in the Federal Register.
    Section 3004(b)(3) of the PHSA, which is entitled ``Subsequent 
Standards Activity,'' provides that the Secretary shall adopt 
additional standards, implementation specifications, and certification 
criteria as necessary and consistent with the schedule published by 
HITAC. As noted in the ``2015 Edition Health Information Technology 
(Health IT) Certification Criteria, 2015 Edition Base Electronic Health 
Record (EHR) Definition, and ONC Health IT Certification Program 
Modifications'' final rule (80 FR 62602), which appeared in the Federal 
Register on October 16, 2015, ONC considers this provision in the 
broader context of the HITECH Act and the Cures Act to grant the 
Secretary the authority and discretion to adopt standards, 
implementation specifications, and certification criteria that have 
been recommended by the HITAC and endorsed by the National Coordinator, 
as well as other appropriate and necessary health IT standards, 
implementation specifications, and certification criteria (80 FR 
62606).
    Under the authority outlined in section 3004(b)(3) of the PHSA, the 
Secretary may adopt standards, implementation specifications, and 
certification criteria as necessary even if those standards have not 
been recommended and endorsed through the process established for the 
HITAC under section 3002(b)(2) and (3) of the PHSA. Moreover, while HHS 
has traditionally adopted standards and implementation specifications 
at the same time as adopting certification criteria that reference 
those standards, the Secretary's authority under section 3004(b)(3) of 
the PHSA is not limited to adopting standards or implementation 
specifications at the same time certification criteria are adopted.
    Finally, the Cures Act amended the PHSA by adding section 3004(c), 
which specifies that in adopting and implementing standards under 
section 3004, the Secretary shall give deference to standards published 
by SDOs and voluntary consensus-based standards bodies.
3. Alignment With Federal Advisory Committee Activities
    The HITECH Act established two federal advisory committees, the 
Health IT Policy Committee (hereinafter referred to as the ``HITPC'') 
and the Health IT Standards Committee (hereinafter referred to as the 
``HITSC''). Each committee was responsible for advising the National 
Coordinator on different aspects of health IT policy, standards, 
implementation specifications, and certification criteria.
    Section 4003(e) of the Cures Act amended section 3002 of the PHSA 
and replaced the HITPC and HITSC with one committee, the HITAC. After 
that change, section 3002(a) of the PHSA now establishes that the HITAC 
advises and recommends to the National Coordinator standards, 
implementation specifications, and certification criteria relating to 
the implementation of a health IT infrastructure, nationally and 
locally, that advances the electronic access, exchange, and use of 
health information. The Cures Act specifically directs the HITAC to 
advise on two areas: (1) a policy framework to advance an interoperable 
health IT infrastructure (section 3002(b)(1) of the PHSA); and (2) 
priority target areas for standards, implementation specifications, and 
certification criteria (section 3002(b)(2) of the PHSA).
    For the policy framework, as described in section 3002(b)(1)(A) of 
the PHSA, the Cures Act tasks the HITAC with providing recommendations 
to the National Coordinator on a policy framework for adoption by the 
Secretary consistent with the Federal Health IT Strategic Plan under 
section 3001(c)(3) of the PHSA. In February of 2018, the HITAC made 
recommendations to the National Coordinator for the initial policy 
framework and subsequently published a schedule in the Federal Register 
and an annual report on the work of the HITAC and ONC to implement and 
evolve that

[[Page 20002]]

framework.319 320 For the priority target areas for 
standards, implementation specifications, and certification criteria, 
section 3002(b)(2)(A) of the PHSA identifies that, in general, the 
HITAC would recommend to the National Coordinator, for purposes of 
adoption under section 3004 of the PHSA, standards, implementation 
specifications, and certification criteria and an order of priority for 
the development, harmonization, and recognition of such standards, 
specifications, and certification criteria. In October 2019, the HITAC 
finalized recommendations on priority target areas for standards, 
implementation specifications, and certification criteria.\321\

4. Interoperability Standards Advisory
    ONC's ISA supports the identification, assessment, and public 
awareness of interoperability standards and implementation 
specifications that can be used by the health care industry to address 
specific interoperability needs.322 323 The ISA is updated 
on an annual basis based on recommendations received from public 
comments and subject matter expert feedback. This public comment 
process reflects ongoing dialogue, debate, and consensus among industry 
and interested parties when more than one standard or implementation 
specification could be used to address a specific interoperability 
need.

    The ISA currently includes the implementation specifications 
proposed in section II.J.6. of this proposed rule. ONC encourages 
interested parties to review the ISA to better understand key 
applications for the implementation specifications it is proposing for 
adoption in this rule.
5. National Technology Transfer and Advancement Act
    The National Technology Transfer and Advancement Act of 1995 
(hereinafter referred to as the ``NTTAA'') (Pub. L. 104-113, enacted 
March 07, 1996; 15 U.S.C. 3701 et seq.) and OMB Circular A-119 require 
the use of, wherever practical, technical standards that are developed 
or adopted by voluntary consensus standards bodies to carry out policy 
objectives or activities, with certain exceptions. The NTTAA and OMB 
Circular A-119 provide exceptions to electing only standards developed 
or adopted by voluntary consensus bodies, namely when doing so would be 
inconsistent with applicable law or otherwise impractical. Agencies 
have the discretion to decline the use of existing voluntary consensus 
standards if it is determined that such standards are inconsistent with 
applicable law or otherwise impractical, and instead use a government-
unique standard or other standard. In addition to the consideration of 
voluntary consensus standards, the OMB Circular A-119 recognizes the 
contributions of standardization activities that take place outside of 
the voluntary consensus standards process. Therefore, in instances 
where use of voluntary consensus standards would be inconsistent with 
applicable law or otherwise impracticable, other standards should be 
considered that meet the agency's regulatory, procurement or program 
needs; deliver favorable technical and economic outcomes; and are 
widely utilized in the marketplace.
6. Proposal To Adopt Standards for Use by HHS
    Consistent with sections 3004(b)(3), 3001(b), and 3001(c) of the 
PHSA, ONC proposes to adopt standards in 45 CFR 170.215(j), (k), (m), 
and (n) on behalf of the Secretary to support the continued development 
of a nationwide health IT infrastructure and support ongoing federal 
alignment of standards for interoperability and health information 
exchange. ONC previously adopted versions of these standards in the 
HTI-4 final rule (90 FR 37130). In addition, ONC is proposing to adopt 
an additional standard in this proposed rule, the HL7 Da Vinci Clinical 
Data Exchange (CDex) Implementation Guide (IG) in 45 CFR 170.215(k)(3). 
Specifically, ONC proposes to adopt the following versions of the 
standards and incorporate them by reference in 45 CFR 170.299(g).
     HL7 FHIR[supreg] Da Vinci Coverage Requirements Discovery 
(CRD) Implementation Guide, Version 2.2.1--STU 2.2 (proposed in 45 CFR 
170.215(j)(1)(ii)).\324\

    ONC previously adopted version 2.0.1--STU 2 of the CRD IG in 45 CFR 
170.215(j)(1)(i) in the HTI-4 final rule (90 FR 37167). This updated 
version of the CRD IG includes improvements such as setting clearer 
expectations for handling failure states, correcting contexts for 
order-dispatch, clarifying expectations for mandatory hook support, and 
setting expectations for endpoints and endpoint discovery. This version 
also includes substantive clarifications, corrections, and enhancements 
for the Coverage Information FHIR extension, which is a core profile in 
the IG by which payer systems communicate coverage and prior 
authorization requirements to provider systems.
     HL7 FHIR[supreg] Da Vinci Documentation Templates and 
Rules (DTR) Implementation Guide, Version 2.2.0--STU 2.2 (proposed in 
45 CFR 170.215(j)(2)(ii)).\325\

170.215(j)(2)(i) in the HTI-4 final rule (90 FR 37167). This updated 
version of the DTR IG includes improvements such as aligning endpoint 
discovery language with CRD IG requirements, addressing CMS enforcement 
discretion regarding the use of X12N 278 transaction standard, 
requiring DTR clients to appropriately manage access to data that is 
sensitive per policy and regulatory requirements when responding to 
queries from a DTR application, and streamlining questionnaire 
retrieval if the CRD workflow is used in combination with the DTR 
workflow.

cancel an entire prior authorization claim instead of cancelling 
individual items, addressing concerns about required fields that are 
specified in the license restricted X12N TRN03 guide (which is 
referenced within the PAS IG), and updating the guide to be compliant 
with US Core IG STU 3.1.1, 6.0.1, and 7.0.0. This version also provides 
new guidance regarding how a provider system can query the payer system 
for a specific prior authorization submission, and new requirements to 
support the ``rest-hook'' subscription channel by which payer systems 
can provide updates on prior authorization submissions.

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

    ONC proposes to adopt version 2.1.0--STU 2.1 of the CDex IG in this 
proposed rule. In section II.H.7. of this proposed rule, HHS is 
proposing to adopt the CDex IG as the attachment standard for prior 
authorization transactions under the required HIPAA Administrative 
Simplification provisions. ONC is separately proposing to adopt this 
standard in 45 CFR 170.215(k)(3) to make it available for use by other 
programs; for instance, programs that may wish to incorporate this 
standard into regulations to align with the HIPAA Administrative 
Simplification requirements, if the proposals in section II.H.7. of 
this proposed rule are finalized.
    In summary, ONC requests comment on our proposals in the CFR 
citations listed in Table 12, and specifically on the proposal to adopt 
standards in 45 CFR 170.215(j), (k), (m), and (n) on behalf of the 
Secretary.
7. Proposed Expiration Dates for Certain Versions of Adopted Standards
    Finally, ONC proposes to add an expiration date of January 1, 2028, 
to corresponding versions of standards currently in 45 CFR 170.215(j), 
(k), (m), and (n) if our proposals to adopt newer versions of adopted 
standards and specifications in 45 CFR 170.215(j), (k), (m), and (n) 
are finalized. ONC proposes this expiration date to provide certified 
health IT developers and other entities required to use these standards 
with a transition period during which they may update and deploy health 
IT conformant with either the existing or updated versions of these 
standards. After the expiration date, only non-expired versions of the 
relevant standards in 45 CFR 170.215(j), (k), (m), and (n) would be 
available for use. ONC believes that a coordinated transition period 
that establishes a single expiration date across the relevant IGs in 45 
CFR 170.215(j), (k), (m), and (n) would create consistency for industry 
and facilitate interoperability by ensuring that health IT systems 
leveraging these standards under different HHS programs use the same 
baseline standards for the same use cases. In addition, ONC believes a 
transition period would allow those health IT developers and other 
entities required to use these standards flexibility to complete 
development towards the existing standards in 45 CFR 170.215(j), (k), 
(m), and (n), and to iterate to newer standards.
    However, ONC also believes that this flexibility may lead to more 
heterogeneity where some deployed health IT uses one standard and other 
deployed health IT uses newer versions of those standards, thus 
complicating shared goals with CMS to facilitate a FHIR-based ecosystem 
for prior authorization, payer to payer exchange, and patient access to 
coverage information. Therefore, ONC is proposing an alternative 
approach to updating these standards. Specifically, as an alternative 
to the proposal above, ONC proposes to remove and replace standards in 
45 CFR 170.215(j), (k), (m), and (n) with the standards it has proposed 
upon the effective date of a final rule, without providing for a 
transition period during which multiple versions of each standard would 
be available for HHS use.
    ONC understands that both certified health IT developers and other 
health IT developers wish to have a single, baseline standard across 
use cases as quickly as practicable for purposes of consistency and 
interoperability. We believe this alternative proposal could help 
advance this goal, particularly in areas such as electronic prior 
authorization. For instance, under this alternative proposal, a 
certified health IT developer with a Health IT Module certified to the 
``provider prior authorization API--documentation templates and rules'' 
criterion for electronic prior authorization in 45 CFR 170.315(g)(32), 
and currently using the standard in 45 CFR 170.215(j)(2)(i) (which is 
the DTR IG, Version 2.0.1--STU 2), would need to use the newer version 
of the standard to remain certified to the criterion in 45 CFR 
170.315(g)(32) as of the effective date of a final rule, which ONC 
proposes in this rule to be the DTR IG, Version 2.2.0--STU 2.2.
    In summary, ONC requests comment on our proposals in the CFR 
citations listed in Table 12, and specifically on the following:

[[Page 20004]]

     The proposal to add an expiration date of January 1, 2028, 
to corresponding standards currently in 45 CFR 170.215(j), (k), (m), 
and (n) if our proposals to adopt newer versions of these standards are 
finalized.
     The alternative proposal to remove and replace the 
standards in 45 CFR 170.215(j), (k), (m), and (n) with the newer 
versions of the standards, without a transition period for use of 
multiple versions.
8. Incorporation by Reference
    The Office of the Federal Register has established requirements for 
materials (for example, standards and implementation specifications) 
that agencies propose to incorporate by reference in the CFR (79 FR 
66267, 1 CFR 51.5(b)). Specifically, 1 CFR 51.5(b)(2) requires agencies 
to discuss, in the preamble of a proposed rule, the ways that the 
materials they incorporate by reference are reasonably available to 
interested parties and how interested parties can obtain the materials; 
and summarize, in the preamble of the proposed rule, the material it 
proposes to incorporate by reference.
    To make the materials ONC intends to incorporate by reference 
reasonably available, it provides a URL for the standards and 
implementation specifications. In many cases, these standards and 
implementation specifications are directly accessible through the URLs 
provided. In most of these instances, access to the standard or 
implementation specification can be gained through no-cost (monetary) 
participation, subscription, or membership with the applicable SDO or 
custodial organization. Alternatively, a copy of the standards may be 
viewed for free at the U.S. Department of Health and Human Services, 
Office of the National Coordinator for Health Information Technology, 
330 C Street SW, Washington, DC 20201. Please call (202) 690-7171 in 
advance to arrange inspection.
    The NTTAA and the OMB Circular A-119 require the use of, wherever 
practical, technical standards that are developed or adopted by 
voluntary consensus standards bodies to carry out policy objectives or 
activities, with certain exceptions. The NTTAA and OMB Circular A-119 
provide exceptions to selecting only standards developed or adopted by 
voluntary consensus standards bodies, namely when doing so would be 
inconsistent with applicable law or otherwise impractical. As discussed 
in section II.J.5. of this preamble, ONC has followed the NTTAA and OMB 
Circular A-119 in proposing standards and implementation specifications 
for adoption, including describing any exceptions in the proposed 
adoption of standards and implementation specifications. Over the years 
of adopting standards and implementation specifications for 
certification, ONC has worked with SDOs, such as HL7, to make the 
standards it proposes to adopt, and subsequently adopt and incorporate 
by reference in the Federal Register, available to interested parties. 
As described previously, this includes making the standards and 
implementation specifications available through no-cost memberships and 
no-cost subscriptions.
    As required by 1 CFR 51.5(a), ONC provides summaries of the 
standards it proposes to adopt in 45 CFR 170.215(j), (k), (m), and (n), 
and subsequently incorporate by reference in 45 CFR 170.299(g). ONC and 
CMS also provide relevant information about these standards and 
implementation specifications throughout the preamble.

Interoperability and Patient Access final rule for impacted payers to 
make available claims and encounter data via Patient Access, Provider 
Access, and Payer-to-Payer APIs. This IG is primarily used to exchange 
financial (claims and encounter) data, with some limited associated 
clinical data.

    Summary: The PDex Plan Net IG defines a FHIR interface to access 
information about a health insurer's insurance plans, their associated 
networks, and the organizations and providers that participate in these 
networks. Publication of these data through a standard FHIR API would 
enable third parties to develop applications through which consumers 
and providers can query the participants in a payer's network that may 
provide services that address their health care needs.

    Summary: The CDex IG helps implementers use FHIR-based interactions 
to exchange specific clinical data between providers and payers (or 
other providers). This IG documents the Direct Query, Task-Based, and 
Attachments transaction approaches for requesting and sending 
information. Key scenarios this IG can support include requesting and 
sending attachments for claims and prior authorization transactions, 
requesting documentation to support payer operations such as claims 
audits, and exchanging clinical data between referring providers.

A. Request for Information: Electronic Event Notifications for Value-
Based Care and Care Coordination

1. Background
    In the 2020 Centers for Medicare & Medicaid Services (CMS) 
Interoperability and Patient Access final rule (85 FR 25510), CMS 
finalized changes to the condition of participation (CoP) regulation in 
42 CFR 482.24(d) to require hospitals--including psychiatric hospitals 
(42 CFR 482.61(f)), Critical Access Hospitals (CAHs) (42 CFR 
485.638(d)), and Rural Emergency Hospitals (REHs) (42 CFR 485.540(d))--
that utilize a health information technology (health IT) system 
conforming to the Health Level Seven (HL7[supreg]) v2.5.1 standard in 
45 CFR 170.205(d)(2) to make a reasonable effort to send electronic 
event notifications to all applicable post-acute care (PAC) services 
providers and suppliers, as well as to any of the following 
practitioners and entities, which need to receive notification of the 
patient's status for treatment, care coordination, or quality 
improvement purposes: (1) the patient's established primary care 
practitioner; (2) the patient's established primary care practice group 
or entity; or (3) other practitioner, or other practice group or 
entity, identified by the patient as the practitioner, or practice 
group or entity, primarily responsible for his or her care. Facilities 
must send real-time electronic notifications to the designated 
practitioners or entities when a patient is admitted to, transferred 
to, or discharged from the facility, including emergency department 
visits. For purposes of this Request for Information (RFI), applicable 
PAC services providers and suppliers would be those PAC services 
providers and suppliers with whom the patient has an established care 
relationship with prior to admission. Additionally, a relationship is 
established when a patient is being transferred or referred for 
additional care for purposes of treatment and/or care coordination 
post-discharge from the hospital.
    In the years since the finalization of these requirements, we have 
received feedback from interested parties about hospitals' success 
implementing electronic event notifications and the degree to which 
these notifications are effectively reaching the recipients intended 
under the regulation. Survey data show that in 2022, three out of four 
non-federal acute care hospitals routinely electronically notified a 
patient's primary care provider upon his or her entry to the hospital's 
emergency department--a percentage that has nearly doubled since 
2012.\331\ Seventy percent of all hospitals routinely electronically 
notified primary care providers inside the hospital's system, whereas 
59 percent of all hospitals routinely electronically notified 
physicians outside the hospital's system. Additionally, in 2023, the 
Office of the Assistant Secretary for Planning and Evaluation (ASPE) 
reported that over 80 percent of nursing homes and home health agencies 
have electronic health records (EHRs),\332\ but only 16 percent of 
hospitals reported sending summary of care records to most PAC 
providers.\333\ While these data reflect broader information exchange 
rather than electronic event notifications specifically, they suggest 
that exchange with PAC providers occurs less frequently than with 
primary care or hospital-based providers. Thus, while the share of 
hospitals reporting that they routinely send electronic event 
notifications has continued to grow over time, we understand that some 
hospitals and providers that should receive these notifications may 
continue to face implementation challenges.

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

    In addition, we recognize that there are entities other than those 
specified in 42 CFR 482.24(d) whose involvement in a patient's care may 
support improved care coordination when they receive electronic 
notifications from hospitals. While current requirements do not 
explicitly state accountable care organizations (ACOs) as required 
recipients of electronic event notifications, many patients are under 
the care of a primary care practitioner or primary care practice group 
that is part of an ACO or other value-based care entity, and the 
regulation does not prohibit hospitals from sending notifications to 
these entities. Additionally, the CMS State Operations Manual hospital 
interpretive guidance (QSO-21-18) \334\ explains that hospitals may 
notify additional entities, including ACOs, based on facility policy or 
patient attribution lists. Commenters who supported the final rule 
noted that greater availability of electronic event notifications 
created the potential for improved care coordination with providers 
outside of hospitals and primary care (for example, behavioral health 
providers, social services providers, etc.) (85 FR 25510). Finally, we 
recognize that payers that conduct care management activities for 
patients may also benefit from receiving patient event notifications.

    Since CMS finalized these requirements in 42 CFR 482.24(d), 
technical standards and solutions that support electronic event 
notifications when a patient is admitted to, transferred to, or 
discharged from a care facility, have continued to advance. For 
example, health information exchanges (HIEs) and other data exchange 
networks continue to facilitate exchange of HL7 v2 admission, 
discharge, and transfer (ADT) data between hospitals, physician groups, 
and other clinicians by automatically routing electronic event 
notification information to organizations that belong to the HIE or 
network.335 336 Survey data from 2023 found that ADT 
capabilities are widely supported by HIEs nationwide, with 96 percent 
of HIEs routinely receiving notifications from hospitals and routing 
them to primary care physicians.\337\

2. Request for Information
CMS seeks public comments on the following:

 Use and Content of Patient Event Notifications

    ++ In the 2020 CMS Interoperability and Patient Access final rule, 
we finalized a minimum set of information that must be shared as part 
of a patient electronic event notification but encouraged hospitals to 
send more information, if possible (85 FR 25587). To what degree are 
hospitals sending additional information with patient electronic event 
notifications and what additional information is being sent?
    ++ What data standards, if any, are hospitals using to send that 
additional information with patient electronic event notifications? 
What standards could be used to improve the minimum set of information 
that currently must be shared?
    ++ What can CMS do to expand the use of patient event notifications 
and provider engagement with those notifications to improve patient 
care?
    ++ What additional information should be included in patient event 
notifications, beyond the minimum set of information that hospitals are 
currently required to send (patient name, treating practitioner name, 
and sending institution name), for more effective and useful patient 
event notifications to better support transitions of care?
    ++ What are the challenges with standardizing patient event 
notifications?
    ++ What operational or technical challenges could hospitals, CAHs, 
and REHs face if CMS were to require additional standardized data 
elements related to patient care to be included with the patient event 
notifications?
    ++ If additional data elements are included in patient event 
notifications, how can technology mitigate any additional clinician 
burden?
    ++ Are there privacy or data governance considerations if hospitals 
include additional information in patient electronic event 
notifications?
    ++ Could additional process requirements or guidance (for example, 
minimums for directory entry updates/corrections/removals or outreach/
verification efforts) improve the quality of notifications or the 
likelihood that notifications are delivered to intended recipients?

 Types of Providers and Entities Receiving Patient Event 
Notifications

    ++ How are ACOs or payers that are currently receiving patient 
event notifications receiving them? What innovative strategies have 
ACOs or payers employed to receive patient event notifications? Do ACOs 
or payers that receive patient event notifications use the information 
in a meaningful way?
    ++ What actions should CMS consider, such as updating the hospital 
CoP, that would encourage or require hospitals to exchange alerts with 
any ACO and other PAC provider and supplier types or payers to which a 
patient is attributed or assigned?
    ++ What challenges prevent hospitals from sharing electronic event 
notifications with ACOs and other PAC provider and supplier types 
today?
    ++ How do hospitals receive authorization to send an electronic 
event notification to an ACO? What are the challenges for hospitals to 
receive that authorization?
    ++ Should CMS encourage or require hospitals to send alerts to 
emergency medical services (EMS)? Behavioral health providers? 
Pharmacies? Social service providers? Other provider types?
    ++ What challenges do long-term care or PAC providers face in 
receiving patient event notifications? What steps could CMS take to 
help address these challenges?
    ++ To what extent do PAC providers currently receive patient 
electronic event notifications in a timely manner to support safe 
admission, transfer, or follow-up care? How have hospitals integrated 
electronic event notification requirements with discharge planning 
requirements to enhance post-discharge continuity of care?
    ++ What processes are in place for attribution and patient matching 
between hospitals and ACOs or other value-based care arrangements, 
payers, PAC facilities, long-term care facilities, social service 
providers, EMS providers, behavioral health providers, etc.? Are these 
adequate? What is missing from these processes?
    ++ How can improved standardization, sharing, and use of provider 
directories contribute to better electronic event notifications?

 Complementary Policy Approaches

    ++ In what ways could CMS leverage other programs, such as the 
Medicare Promoting Interoperability Program to advance the use of 
patient event notifications? For instance, what measures could CMS add 
to the Medicare Promoting Interoperability Program for eligible 
hospitals and CAHs that assess the degree to which notifications are 
sent to recipients?
    ++ What are other ways that CMS could incentivize improved delivery 
and use of patient event notifications?
    ++ In what ways could CMS coordinate with the Office of the 
National Coordinator for Health Information Technology (ONC) to 
establish certification criteria for health IT that would enable 
authorized users, including authorized ACOs or other value-based care 
providers, to be able to subscribe to patient event notification 
alerts?
    ++ How could CMS leverage the TEFCA \342\ network to improve the 
quality of notifications and/or improve the likelihood that electronic 
event notifications shared by hospitals are able to reach authorized 
recipients?

February 11). TEFCA. Retrieved from https://healthit.gov/policy/tefca/.

---------------------------------------------------------------------------
 Technical Approaches to Patient Electronic Event Notifications

    ++ Under current CoP requirements, hospitals have significant 
flexibility in the technical approaches they use to implement patient 
electronic event notifications. What technical approaches are most 
widespread among hospitals to send patient electronic event 
notifications? What are the key benefits and challenges hospitals face 
with current technical approaches used?
    ++ What technical approach(es) would provide additional 
functionality/

[[Page 20008]]

value to the patient event notification process (for example, the HL7 
Subscriptions Framework and HL7 Da Vinci Unsolicited Notifications IG 
discussed above)? Can the HL7 FHIR Da Vinci Member Attribution (ATR) 
List IG (ATR List IG) be utilized as part of patient event 
notifications? \343\ How does network participation or status impact 
this process?

List IG. Retrieved from http://hl7.org/fhir/us/davinci-atr/ImplementationGuide/hl7.fhir.us.davinci-atr.
---------------------------------------------------------------------------

    ++ How can CMS incentivize or require hospitals to adopt more 
advanced approaches to electronic event notifications? Are the CoPs the 
most appropriate policy vehicle to define technical requirements for 
notifications? What other policy levers should CMS consider besides the 
CoPs to more effectively implement new technical approaches to 
electronic event notifications?
    ++ What standards-based mechanisms exist or could be improved to 
support authorized ACOs or other value-based care entities, payers, and 
other provider types to be able to subscribe to patient event 
notification alerts? For example, could certain standards or 
requirements for patient matching improve event notifications?

 Enforcement

    ++ To what degree have existing enforcement mechanisms for the CoPs 
helped to advance compliance with patient event notification 
requirements?
    ++ What additional steps, if any, should CMS take to strengthen 
existing enforcement mechanisms and address concerns about some 
hospitals not adhering to the patient event notification requirements?
    ++ What additional guidance, technical assistance, or other 
supports could CMS provide to help hospitals improve compliance and 
effective use of patient event notifications?

B. Request for Information: Increasing Health Care Resiliency

1. Health Care Cybersecurity Background
    The health care system is increasingly reliant on a digital 
infrastructure to store and transmit sensitive health care data, and 
more organizations are consolidating their resources and technology to 
improve efficiency. The reliance on digital infrastructure and large 
information technology (IT) systems, run by industry players that span 
the nation and interact with a high volume of large payers, may create 
vulnerabilities that could be exploited by cybercriminals. Recent 
security breaches, ransomware attacks, and other incidents have 
disrupted health care operations, put patient safety and privacy at 
risk, and potentially undermined public and private sector initiatives 
to move towards new standards and technologies. The Centers for 
Medicare & Medicaid Services (CMS) is committed to enhancing the 
resilience of the health care system against cyber threats.
    Statistics show a disturbing trend in the vulnerability of health 
care organizations to cyber threats. As noted in the ``HIPAA Security 
Rule To Strengthen the Cybersecurity of Electronic Protected Health 
Information'' proposed rule (90 FR 898) (hereinafter referred to as the 
``HIPAA Cybersecurity proposed rule''), which appeared in the Federal 
Register on January 6, 2025, between 2018 and 2023, the number of 
breaches of unsecured protected health information (PHI) reported to 
the Department of Health and Human Services (HHS) grew at an alarming 
rate (100 percent increase), as did the number of individuals affected 
by such breaches (950 percent increase). The reports reflect rampant 
escalation of cyberattacks using hacking (260 percent increase) and 
ransomware (264 percent increase) (90 FR 913). Cyber incidents 
affecting hospitals and health systems have led to extended care 
disruptions, delayed medical procedures, and data loss, all putting 
patient safety at risk. These breaches impact a variety of IT systems, 
including network servers, email accounts, electronic health records 
(EHRs), desktop and laptop computers, and portable electronic devices. 
With 77 percent of breaches of unsecured PHI reported to the Office for 
Civil Rights (OCR) that affected 500 or more individuals impacting 
network servers in 2023, it is critical to protect health systems and 
patients with vigilance.\344\

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

    According to a 2025 report, health care has remained the most 
expensive industry for electronic data breaches since 2011, with the 
average data breach costing $7.42 million.\345\ The sector continues to 
be highly vulnerable to cyberattacks, putting patient safety at risk. 
Notably, financial consequences associated with breaches have worsened 
in recent years. The cost of post-breach responses and lost business 
rose by 11 percent from 2023 to 2024, underscoring the persistent 
challenges that health care organizations face in securing sensitive 
data.

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

    There are several statutes and regulations promulgated to prevent 
and mitigate data breaches within the health care sector. First, as 
part of HIPAA, Congress authorized the Secretary to promulgate 
standards for protecting the privacy and security of certain health 
information.\346\ The HIPAA Security Rule requires that covered 
entities and their business associates implement administrative, 
physical, and technical safeguards to ensure the confidentiality, 
integrity, and availability of electronic protected health information 
(ePHI).347 348 These safeguards include many long-standing 
cybersecurity best practices, such as conducting periodic risk 
analyses, implementing risk management processes, establishing data 
backup and disaster recovery plans, implementing security incident 
procedures, conducting security training, implementing access and audit 
controls, reviewing system activity, and encrypting ePHI where 
reasonable and appropriate.\349\ The HIPAA Security Rule also requires 
covered entities and business associates (both defined in 45 CFR 
160.103) to review and modify their security measures to continue 
provision of reasonable and appropriate protection of ePHI.\350\
---------------------------------------------------------------------------

    \346\ See sections 262(aa) and 264(c) of Public Law 104-191.

    \350\ See 45 CFR 164.306(e).
---------------------------------------------------------------------------

    Second, the Federal Information Security Management Act of 2002 
(hereinafter referred to as ``FISMA'') \351\ (Title III, Pub. L. 107-
347, enacted December 17, 2002) (amended in 2014) provides for 
additional guidelines and security standards; it requires all federal 
agencies to implement agency-wide FISMA-compliant information security 
programs and to review these programs annually. FISMA requirements 
impact both federal agencies and contractors to the extent: (a) 
contractors collect or maintain information ``by or on behalf of an 
agency;'' or (b) there are ``information systems used or operated by an 
agency or by a contractor of an agency or other organization on behalf

[[Page 20009]]

of an agency.'' \352\ As a consequence, state and local government 
agencies that receive federal funding and/or administer federal 
programs, and private organizations with a contractual relationship 
with the federal government that involves the creation, collection, 
storage, and/or processing of federal data may be subject to FISMA. For 
example, Medicare Administrative Contractors (MACs), private health 
care organizations that contract with CMS to administer Part A and Part 
B medical claims and claims for durable medical equipment, prosthetics, 
orthotics, and supplies (DMEPOS) items for Medicare fee-for-service 
(FFS) beneficiaries, are subject to FISMA requirements according to the

    Third, the HITECH Act was enacted to promote nationwide adoption 
and standardization of health IT to support electronically sharing 
clinical data.\356\ Congress acknowledged that security challenges 
emerged with health IT adoption and mandated stronger safeguards for 
privacy and security of ePHI in the HITECH Act. Among other changes 
with respect to HIPAA, the HITECH Act extended the HIPAA Security Rule 
to apply to business associates, making them directly liable for 
violations of the HIPAA Security Rule and required business associate 
agreements to include new security-related provisions.\357\ In 
addition, the HITECH Act directed the Secretary to regularly issue 
guidance on the most appropriate and effective technical 
safeguards.\358\ The HITECH Act was amended in 2021 to require the 
Secretary to consider, as a mitigating factor, adequately demonstrated 
implementation of recognized security practices in certain HIPAA

    The White House's 2024 National Security Memorandum on Critical 
Infrastructure Security and Resilience reaffirmed ``Healthcare and 
Public Health'' as a critical infrastructure sector, underscoring the 
ongoing federal focus on cybersecurity protection for health care 
systems.\360\ Subsequently, HHS published the HIPAA Cybersecurity 
proposed rule, which would strengthen cybersecurity by updating the 
HIPAA Security Rule's standards to better address ever-increasing 
threats to the health care sector. These efforts reflect the federal 
government's commitment to both addressing data breaches through 
enhanced cybersecurity measures and advancing secure digital health 
innovation through foundational initiatives announced in support of the 
new digital health ecosystem. Key components of these initiatives 
include enhanced Medicare Plan Finder tools, improved interoperability 
frameworks, and early adopter programs, all designed with cybersecurity 
as a core element.361 362 These initiatives demonstrate HHS' 
recognition that effective health care technology adoption must be 
balanced with comprehensive security measures to protect patient data 
and maintain system resilience. Several other HHS agencies have issued 
guidance on securing electronic information systems and electronic 
health information (EHI). In 2016, ONC released the Safety Assurance 
Factors for EHR Resilience (SAFER) Guides, which provide foundational, 
infrastructure, and clinical process guides to support health care 
organizations in addressing EHR best practices and methods to optimize 
safe use of EHRs.\363\ To encourage adoption of these recommended 
safety practices, CMS established attestation measures as part of the 
Medicare Promoting Interoperability and the MIPS Promoting 
Interoperability performance category of the Quality Payment Program 
(QPP).\364\ In 2025, ONC released an updated version of the SAFER 
Guides, which streamline the best practices presented in the guides and 
incorporate recent evidence on safety practices.\365\

    In 2023, the Health Sector Coordinating Council (HSCC), the 
Cybersecurity and Infrastructure Security Agency (CISA), and HHS began 
working together to produce a toolkit with resources, training, 
information, and tools to support efforts to improve health care 
cybersecurity. Among the

[[Page 20010]]

resources in this toolkit is the Healthcare Sector Cybersecurity 
Strategy Concept Paper, which outlines a health care cybersecurity 
strategy built on the 2023 National Cybersecurity 
Strategy.369 370 Specifically, the paper focuses on four 
pillars of action to promote resiliency among hospitals, patients, and 
communities: (1) produce Cybersecurity Performance Goals (CPGs), (2) 
work with Congress to develop incentives and support for hospitals to 
improve cybersecurity, (3) increase accountability and coordination 
within the health care system, and (4) expand and mature the one-stop 
shop within HHS for health care sector cybersecurity. The CPGs are 
delineated into two categories to help health care entities prioritize 
cybersecurity practices: (1) essential goals, which include mitigating 
known vulnerabilities; email security; multifactor authentication; 
basic cybersecurity training; strong encryption; revoking credentials 
for departing workforce members, including employees, contractors, 
affiliates, and volunteers; basic incident planning and preparedness; 
unique credentials; separate user and privileged accounts; and vendor/
supplier cybersecurity requirements; and (2) enhanced goals, which 
include asset inventory; third-party vulnerability disclosure; third-
party incident reporting; cybersecurity testing; cybersecurity 
mitigation; detecting and responding to relevant threats and tactics, 
techniques, and procedures; network segmentation; centralized log 
collection; centralized incident planning and preparedness; and 
configuration management.\371\

implementation guide (IG) is intended to help Health Care and Public 
Health Sector organizations implement the NIST Cybersecurity Framework 
as an integral part of their cybersecurity and cyber risk management 
programs. Also in 2023, the HHS 405(d) Program published the ``Health 
Industry Cybersecurity Practices: Managing Threats and Protecting 
Patients,'' and the Federal Trade Commission (FTC) produced the ``Start 
with Security: A Guide for Business,'' both containing best practices, 
methodologies, and guidelines for protecting the security of 
ePHI.373 374 In February 2024, NIST published an updated

    Despite these efforts, the health care sector remains a prime 
target for cyberattacks, and these attacks have a significant impact on 
stakeholders. Cyberattacks can lead to data breaches, loss of privacy, 
and potentially life-threatening disruptions in care. For example, 
ransomware attacks can lock health care providers out of critical IT 
systems, delaying surgeries, patient care, and access to 
medication.\376\ Health care providers face operational disruptions, 
financial losses due to system downtimes, and damage to their 
reputation.\377\ At hospitals specifically, cyberattacks can lead to 
process slowdowns, cancelled procedures, delayed hospital or unit 
lockdowns and transfers, increased wait times for individuals, and 
decreased health care provider capacity.\378\ The post-attack 
restoration of IT systems and data integrity often requires substantial 
resources.\379\ Insurance payers and other entities are affected by 
compromised claims systems, fraudulent activities following data 
breaches, and increased premiums due to the rising costs of 
cybersecurity insurance.380 381 382

C. Request for Information: Improving Implementation of Payer 
Application Programming Interface Technology

1. Background
    As the U.S. health care system increasingly adopts digital 
solutions to enhance care delivery, the interoperability of these 
systems becomes crucial. Interoperability, facilitated by application 
programming interfaces (APIs), allows different health information 
technology (health IT) systems and software apps to communicate, 
exchange data, and effectively use the information that has been 
exchanged.\383\
---------------------------------------------------------------------------

    \383\ Under section 3000(5) of the PHSA, health IT is defined as 
``hardware, software, integrated technologies or related licenses, 
intellectual property, upgrades, or packaged solutions sold as 
services that are designed for or support the use by health care 
entities or patients for the electronic creation, maintenance, 
access, or exchange of health information.'' ONC has adopted this 
definition of health IT in 45 CFR 170.102.
---------------------------------------------------------------------------

    The Centers for Medicare & Medicaid (CMS) interoperability 
initiative has a mission to ``promote the secure exchange, access, and 
use of electronic health information (EHI) to better support informed 
decision making and a more efficient health care system.'' \384\ To 
support this mission, CMS has taken several actions to improve 
interoperability in health care, including working with standards 
developing organizations (SDOs) to promote the development of Health 
Level Seven (HL7[supreg]) Fast Healthcare Interoperability Resources 
(FHIR[supreg]) standards and associated implementation guides (IGs), 
implementing standardized APIs at CMS, and requiring impacted payers to 
exchange data via FHIR APIs in the 2020 CMS Interoperability and 
Patient Access and 2024 CMS Interoperability and Prior Authorization 
final rules (85 FR 25510 and 89 FR 8758).\385\
---------------------------------------------------------------------------

    \384\ Centers for Medicare & Medicaid Services (2024). CMS 
Interoperability. Retrieved from https://www.cms.gov/priorities/key-initiatives/burden-reduction/interoperability/cms-interoperability.
    \385\ Standardized APIs enable one software applicable to access 
the services or data of another, securely and efficiently, without 
human intervention.
---------------------------------------------------------------------------

    Even as standardized API usage increases throughout the health care 
system, CMS continues to receive stakeholder reports of incomplete or 
broken API implementations, which have the potential to impede 
interoperability, patient safety, and the security of EHI. In response 
to the 2022 CMS Interoperability and Prior Authorization proposed rule, 
commenters emphasized the importance of making available test data, 
staging environments, sandboxes, and other mechanisms to help 
developers test their software and prevent non-standard implementation 
of APIs across the industry. For example, missing or incorrect data due 
to non-conformant implementation could result in incomplete health 
information being exchanged. CMS seeks to reduce these risks and to 
improve health care interoperability by exploring opportunities to 
ensure that required APIs are effectively implemented. While CMS is 
proposing to require certain IGs in this rule to improve API 
interoperability, strengthening oversight mechanisms could further 
enhance standardization and ensure APIs are implemented correctly. We 
emphasize that we are not proposing a requirement for certification in 
this proposed rule; rather, CMS seeks to establish a roadmap to promote 
consistent implementation among payers.
    As discussed in section II.A.4.b. of this proposed rule, the 
technical requirements for the FHIR APIs we finalized in the 2020 CMS 
Interoperability and Patient Access and 2024 CMS Interoperability and 
Prior Authorization final rules include general requirements for 
impacted payers to test their interoperability APIs (see, for instance, 
requirements for Medicare Advantage (MA) plans in 42 CFR 
422.119(c)(2)). We are considering how we can build on those testing 
requirements. For instance, the open-source Inferno testing tool is 
available for developers to create, execute, and share conformance 
tests for numerous FHIR-based standards and IGs. The Office of the 
National Coordinator for Health Information Technology (ONC)

[[Page 20012]]

has developed test kits within Inferno that can be used by payers to 
test their APIs' conformance with certain versions of the FHIR 
standards and IGs.\386\ Inferno is available to download for local 
deployment and is hosted on ONC's website at https://inferno.healthit.gov/.
---------------------------------------------------------------------------

    \386\ Office of the National Coordinator for Health IT. (n.d.). 
Inferno on HealthIT.gov Test Kits. Retrieved from https://inferno.healthit.gov/test-kits/ kits/.
---------------------------------------------------------------------------

    CMS strongly encourages payers to utilize available testing tools, 
such as Inferno, to meet the existing testing requirements. We also 
encourage payers to publish their test results to demonstrate 
conformance with the technical requirements. We are further considering 
additional requirements that would increase transparency as to whether 
an API has been tested for conformance through such tools. For 
instance, we could consider requiring impacted payers to publish 
testing results or report them to CMS, for CMS to potentially publish. 
Doing so could increase transparency and trust that API technology 
deployed by payers has been properly implemented to facilitate 
interoperability. While such a requirement may initially focus on 
testing with the existing Inferno tools, we are also interested in how 
such a requirement could incorporate other testing tools that may be 
developed in the future to meet payers' needs. For instance, the 
National Coordinator has historically approved alternative test methods 
under the ONC Health IT Certification Program.\387\
---------------------------------------------------------------------------

    \387\ Office of the National Coordinator for Health IT. (2021, 
October 18). ONC-Approved Testing Partners. Retrieved from https://www.healthit.gov/topic/certification-ehrs/onc-approved-testing-partners.
---------------------------------------------------------------------------

    We have also received feedback from the public that, in addition to 
demonstrating API conformance with the required standards, the 
availability of a ``sandbox environment'' is an important approach to 
ensuring that systems seeking to access an API can test and develop 
robust connections. We believe that such environments could accelerate 
durable connections between third-party apps and payers' APIs, and we 
are considering whether to propose to require impacted payers implement 
and maintain a sandbox environment for testing.
    While the ideas we have described previously could be proposed as 
discrete provisions for each API, we also request public comment on an 
overarching certification approach to the interoperability APIs. For 
instance, the ONC Health IT Certification Program's testing and 
certification infrastructure could provide a streamlined approach to 
demonstrate conformance with technical requirements. The ONC Health IT 
Certification Program, established under section 3001(c)(5) of the 
PHSA, is a voluntary program for health IT developers and is designed 
to ensure the availability and functionality of certified health IT 
(referred to as Health IT Modules) using adopted health IT standards. 
In the program, developers certify their Health IT Modules by 
demonstrating conformance to standards adopted by the Department of 
Health and Human Services (HHS) through specific certification criteria 
and using test procedures (that may have associated test tools and/or 
test data) approved by the Secretary. Certification criteria are 
established via notice-and-comment rulemaking, updated, and maintained 
by ONC. While the ONC Health IT Certification Program has predominantly 
focused on electronic health records (EHRs) and other health IT systems 
used by providers, certification criteria under the program may also be 
developed for health IT intended for other types of users.
    Such an approach was explored as part of the HTI-2 proposed rule, 
in which ONC proposed certification criteria in 45 CFR 170.315(g)(30), 
(32), (33), (35), and (36) intended for health IT used by payers. These 
certification criteria corresponded to each of the interoperability 
APIs finalized in the 2020 CMS Interoperability and Patient Access and 
2024 CMS Interoperability and Prior Authorization final rules (89 FR 
63498 and 63582-63590) and were designed to complement and support 
CMS's interoperability efforts to improve access to EHI for patients, 
providers, and payers through FHIR APIs. The proposed certification 
criteria would have allowed health IT developers to voluntarily certify 
their products to standards and specifications in 45 CFR 170.213 and 45 
CFR 170.215 (89 FR 63580). In the HTI-4 final rule, ONC finalized three 
new Prior Authorization API certification criteria in 45 CFR 170.315 
(g)(31), (32), and (33) (90 FR 37175). ONC subsequently withdrew the 
remaining HTI-2 proposed rule proposals that had not yet been finalized 
as part of a notice which appeared in the Federal Register on December 
29, 2025 (90 FR 60602). While ONC has not finalized those proposals, we 
are still seeking comment on whether such an approach could provide 
value in the future.
2. Request for Information
     Roadmap for Consistent Implementation of Payer API 
Technology

    ++ What program components are most important to establishing 
robust oversight mechanisms for payers' APIs? How can CMS balance 
testing requirements to ensure interoperability while minimizing burden 
on payers and health IT developers delivering technology to payers?
    ++ What aspects of API implementation pose the most significant 
implementation difficulties, and where do commenters perceive the 
potential for lack of conformance with the API technical requirements?
    ++ What aspects of API implementation should be prioritized for 
testing? Where would testing requirements have the greatest impact and 
benefit?
    ++ What are current best practices for testing conformance with API 
technical requirements?
    ++ What should testing platforms and processes look like?
    ++ What existing API testing tools (besides the Inferno tool 
discussed above) could be employed as part of the testing for payer 
APIs?
    ++ What criteria could or should be used to identify new API 
testing tools?
    ++ In addition to initial conformance testing, should CMS establish 
requirements for interoperability testing between and among multiple 
systems, that are conformant to identified IGs, to facilitate real-
world deployments of such systems?

 Certification of Payer API Technology

    ++ What value would the certification of payer API technology 
provide to payers, providers, and patients? What would be the benefits 
and burdens of requiring certification of payer API technology for 
payers, providers, and patients?
    ++ If ONC were to establish criteria for payer API technology, 
should CMS require certification to meet payer API requirements, or 
should such certification be made available solely on a voluntary 
basis? Would payers or developers of API technology providing solutions 
to payers be likely to obtain certification on a voluntary basis?
    ++ What could a roadmap to certifying payer API technology look 
like? What are the intermediate steps that may be taken toward payer 
API technology certification?
    ++ If payer API technology certification is not appropriate at this 
time, how would CMS and ONC know when conditions exist to propose 
certification criteria and requirements?

[[Page 20013]]

D. Request for Information: Step Therapy

1. Step Therapy Background
    Step therapy is a form of utilization management used by some 
payers to control costs.\388\ It is often referred to as a ``fail-
first'' strategy because it requires patients to try various preferred 
prescription drugs and find them to be ineffective or contraindicated 
for patient use before the payer will approve a more expensive or non-
preferred drug option.\389\ In some cases, step therapy programs 
require patients to try one or more generic drugs before brand name 
drugs are approved or to try a preferred class of drugs that are less 
costly before allowing a switch to a more expensive or non-preferred 
drug class.\390\ Authorization of the non-preferred drug may require 
attestation by the provider that the patient took the initial drug and 
experienced adverse effects or that the initial drug provided 
inadequate clinical benefit. Legislation requiring payers to allow 
providers to exempt patients from step therapy protocols under certain 
circumstances, such as if the drug was ineffective in the past or if 
the drug will likely cause adverse reaction or harm, has been enacted 
in 29 states.\391\ As set forth in the ``Modernizing Part D and 
Medicare Advantage To Lower Drug Prices and Reduce Out-of-Pocket 
Expenses'' final rule (84 FR 23832), which appeared in the Federal 
Register on May 23, 2019, the Centers for Medicare & Medicaid Services 
(CMS) allowed Medicare Advantage (MA) plans to apply step therapy as a 
utilization management tool for Part B drugs to both prevent 
overutilization of medically unnecessary health services and control 
costs, but only if, starting contract year 2020, the plan uses a 
Pharmacy and Therapeutic committee to review and approve the step 
therapy programs (84 FR 23832).

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

    When developed and implemented appropriately, step therapy can use 
evidence-based criteria along with clinically-reasonable provisions for 
exceptions to encourage more rational prescribing in an effort to 
control drug costs and ensure that patients are receiving clinically 
based data-driven drug regimens.\392\ However, if step therapy 
requirements are based on poor evidence or implemented using an 
inflexible approach, it can cause clinical issues for patients forced 
to return to a drug or class of drugs that were previously ineffective, 
potentially delaying access to treatments, hindering adherence to drug 
regimens, and risking severe side effects and disease progression for 
patients. A concerning instance of step therapy interrupting a 
preferred drug regimen can be observed when a patient changes payers 
due to a change in job or employer-provided coverage. In this 
circumstance, the patient who had previously failed a drug regimen may 
unexpectedly be subjected to new step therapy requirements, forcing 
them to switch from their current drug to whatever agent is the ``first 
step'' in their new plan. In states without laws regulating step 
therapy practices, this means that providers are unable to choose what 
they believe to be the best treatment options for their patients but 
instead must try alternative options first that have been mandated by 
the payer. In the 29 states that require payers to allow exemptions, 
providers must either try the drug(s) the payer's step therapy protocol 
requires or complete paperwork justifying their treatment choice, which 
can impose a significant burden on the provider and can negatively 
impact patients as they wait for effective treatment.\393\

2. Request for Information
    While payers should be allowed to implement reasonable evidence-
based policies to avoid unnecessary expenses incurred by suboptimal 
prescribing practices, CMS is soliciting public comment on whether 
increased interoperability of information technology (IT) systems 
across payers could be used to make utilization management policies, 
such as step therapy, more transparent.
    CMS is interested in how technology and data sharing, such as via 
the Payer-to-Payer application programming interface (API), might 
streamline the step therapy process by giving payers access to 
historical drug therapies that a patient may have already tried and 
automating the utilization management process rather than requiring 
providers to submit historical records or attest to prior drug 
regimens. CMS seeks comment on how technology may facilitate step 
therapy determinations and improve current step therapy processes.

 Technology and Step Therapy

    ++ How could increased interoperability make the criteria for 
covering a given drug clear to patients and providers; allow providers 
to obtain permission to override the step therapy protocol for 
clinically appropriate documented reasons (for example, a patient's 
intolerance of or poor response to first step treatments); and increase 
the efficiency of the process for submitting information, ideally as 
part of electronic prescribing systems?
    ++ How could technology and data sharing, such as via the Payer-to-
Payer API, support streamlined step therapy solutions? For example, if 
a patient changes plans, how could technology facilitate honoring step 
therapy determinations that a prior payer completed? Additionally, how 
could data sharing between payers provide automated solutions to 
evaluating step therapy requirements?
    ++ What other technical solutions, in addition to or in lieu of, a 
Payer-to-Payer API, could facilitate fast, efficient, accurate, and 
streamlined step therapy determinations?

 Step Therapy by Previous Payer

    ++ What are the standard practices for payers applying step therapy 
criteria to a new patient who is currently stable on a medication? How 
does the payer obtain documentation to support that a patient has 
satisfied a previous payer's step therapy requirements or is currently 
stable on the drug(s)?
    ++ Given that payers may have different formularies and step 
therapy requirements, how can payers evaluate step therapy requirements 
and formulary options from a previous payer to apply their step therapy 
requirements to the same medication?
    ++ If a previous payer has already required step therapy and made a 
determination, what obligation should a new payer have to recognize and 
apply the previous payer's determination, if any, and how could this 
reduce burden on providers and payers?
    ++ If a new payer requires step therapy after a patient has 
satisfied a previous payer's step therapy requirements, what is the 
value of requiring the patient to meet step therapy requirements again 
for the new

[[Page 20014]]

payer? To reduce burden, is there a timeframe during which payers 
should honor a step therapy determination from a previous payer, and, 
if so, what would be the appropriate timeframe?
    ++ What information is necessary or beneficial for a new payer to 
receive to make decisions about accepting a prior payer's step therapy 
decisions? Additionally, what challenges could payers face to implement 
systems to support this transaction, and would there be a cost impact 
to payers?

E. Request for Information: Laboratory Tests and Durable Medical 
Equipment, Prosthetics, Orthotics, and Supplies Items

1. Laboratory Tests and Durable Medical Equipment, Prosthetics, 
Orthotics, and Supplies Items Background
    Prior authorization requirements from health insurers for 
laboratory tests and Durable Medical Equipment, Prosthetics, Orthotics, 
and Supplies (DMEPOS) items have emerged, in some instances, as a 
potential barrier to care and coverage, impacting both patients and 
health care providers. While prior authorization has a role to play for 
program integrity purposes, such as preventing fraud and reducing waste 
on unnecessary medical resources, it may also prevent or delay 
appropriate care with improper denials and extended decision periods.
    CMS has taken meaningful steps to reduce the burden associated with 
prior authorization processes across the health care industry. For 
instance, the 2024 CMS Interoperability and Prior Authorization final 
rule included requirements for impacted payers to improve prior 
authorization processes through policies and technology (89 FR 8758). 
Beginning in 2027, impacted payers will be required to implement and 
maintain a Prior Authorization application programming interface (API) 
to improve the electronic exchange of health care data related to the 
prior authorization processes (89 FR 8897). Once operational, impacted 
payers' Prior Authorization APIs will be populated with a list of non-
drug items and services requiring prior authorization, as well as 
documentation requirements, which should facilitate the assembly of 
necessary information for health care providers to submit a complete 
prior authorization request. In addition, through the Wasteful and 
Inappropriate Service Reduction (WISeR) model, CMS is aiming to 
leverage advanced technology plus clinician review to assure that 
Medicare payments for certain high-risk items/services are timely and 
appropriate.\394\ WISeR will run for 6 performance years from January 
1, 2026 to December 31, 2031 in six states: New Jersey, Ohio, Oklahoma, 
Texas, Arizona, and Washington.\395\

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

    While CMS has made strides towards streamlining prior authorization 
processes, such as in the 2024 CMS Interoperability and Prior 
Authorization final rule, current prior authorization processes in the 
private health insurance industry may lead to unintended negative 
impacts. While Medicare fee-for-service (FFS) does not require prior 
authorization for laboratory tests, recent publications have raised 
concerns that the length of time it takes for prior authorization 
requests to be approved for laboratory tests from private payers may 
cause delays in care.396 397 398 Timely access to diagnostic 
testing is a critical component to manage acute and chronic conditions, 
and delays may hinder effective treatment decisions and ultimately 
patient safety. For example, when a health care provider places an 
order for a patient to have laboratory tests drawn, the health care 
provider often sends the patient to a laboratory that is in the same 
facility, or nearby, to have laboratory tests drawn that day. Often, 
the patient and laboratory do not know that prior authorization is 
required or whether a prior authorization request has been submitted 
until after laboratory tests are drawn or the claims for the laboratory 
tests are denied. When a laboratory discovers that prior authorization 
is missing, it may not be authorized to start the process itself. We 
have received anecdotal feedback that some payers do not allow a 
laboratory to request prior authorization.\399\ Further, if the patient 
waits for notice of an approved prior authorization decision, it could 
delay medically necessary testing, which has the potential to delay 
diagnosis and treatment, leading to worsened health outcomes.

    \399\ In the MA context, MA plans must allow laboratories to 
initiate prior authorization requests because a laboratory is a 
``provider'' that furnishes, or intends to furnish, services to the 
enrollee. See 42 CFR 422.566(c)(1)(ii).
---------------------------------------------------------------------------

    Additionally, a review of currently published literature indicates 
that some Medicare Advantage (MA) plans may be misusing prior 
authorizations to inappropriately delay or deny services or 
payment.\400\ Some MA plans may improperly rely on the Medicare Part B 
laboratory ``date of service'' policy (hereinafter referred to as 
``DOS'' policy) in 42 CFR 414.510(a), which provides that the DOS is 
generally the date of specimen collection for purposes of determining 
how a laboratory service should be billed to Medicare, as a basis to 
deny prior authorization.\401\ In the MA context, when a health care 
practitioner does not get prior authorization before ordering a 
laboratory test or before the sample is collected, which is often the 
case, the laboratory will attempt to get prior authorization once it 
receives the order. In some cases, the MA plan may deny the 
laboratory's prior authorization request on the grounds that the DOS 
has already occurred, citing the Part B laboratory DOS policy as the 
basis for this determination. This practice of relying on the DOS 
policy to deny prior authorization is not compliant with rules in the 
MA program. The DOS policy is a Medicare FFS policy that does not set 
the scope of basic benefits applicable to the MA program.\402\ When

[[Page 20015]]

applying prior authorization for basic benefits, prior authorization 
processes for MA coordinated care plans may only be used to confirm the 
presence of diagnoses or other medical criteria that are the basis for 
coverage determinations for the specific item or service or to ensure 
an item or service is medically necessary based on standards specified 
in 42 CFR 422.101(c)(1).\403\ While MA plans could choose to adopt the 
laboratory DOS policy as a payment or billing rule in their contracts 
with health care providers, it would be wholly inconsistent with 42 CFR 
422.138(b) to apply the DOS policy as a basis to deny a request for 
prior authorization of laboratory services that have not yet been 
performed.

    Further, CMS is aware that differences between medical 
documentation requirements for Medicare Administrative Contractors 
(MACs), MA plans, and other payers may lead to health care provider 
confusion and burden. Specifically, some MACs and MA plans may not 
accept a test requisition form (TRF) or a physician attestation as 
valid medical documentation to establish the medical necessity of a 
laboratory test, which can contribute to administrative burden and 
consume valuable time from health care providers that could otherwise 
be spent with patients.
    Similar issues may arise with certain prior authorization requests 
related to DMEPOS items since prior authorization is required for many 
types of DMEPOS items. Beginning January 1, 2026, MA organizations, 
state Medicaid and CHIP FFS programs, Medicaid managed care plans, and 
CHIP managed care entities are required to provide notification of 
prior authorization decisions within 7 calendar days after receiving a 
standard prior authorization request and 72 hours after receiving an 
expedited prior authorization request.\404\ While that shortened 
decision timeframe should alleviate some of the burden associated with 
prior authorization requests, industry representatives have reported 
that differing documentation requirements can lead to denials of prior 
authorization requests, resulting in extra time spent by clinicians to 
complete additional medical evaluations and justifications for DMEPOS 
items.405 406 Another area of concern is length of the prior 
authorization determination appeals process, which can also take months 
to complete, further prolonging patient access to necessary equipment.

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

    Similar to prior authorizations generally, varying payer prior 
authorization requirements can add complexity and burden for health 
care providers and patients to receive prior authorization for DMEPOS 
items and laboratory tests. In addition, DMEPOS items face additional 
coordination challenges, as laboratories and the DMEPOS suppliers are 
often reliant on the ordering health care provider to submit a prior 
authorization request on behalf of the patient; however, because the 
medical item or service is not being furnished by the health care 
provider, communication gaps may occur if not all parties understand 
the responsibilities and requirements of the prior authorization 
process. Moreover, differing prior authorization requirements across 
payers may result in confusion and errors in submissions. This could 
disrupt health care provider workflows and increase administrative 
costs, which can lead to denials for procedural reasons and appeals 
that may take months of additional administrative costs and efforts.
    For example, in a recent scenario provided by a wheelchair supplier 
to CMS, a health care provider may order a wheelchair to help a patient 
regain mobility. In many instances, the DMEPOS supplier is reliant on 
the health care provider to submit a prior authorization request on 
behalf of the patient, including the supporting documentation. If prior 
authorization was not submitted by the health care provider or was 
inadequately supported, then the payer may deny the claim, which could 
lead to the wheelchair being taken from the patient, the patient being 
billed for the DMEPOS item, the DMEPOS supplier not receiving payment 
for the wheelchair, or appeals that take time from the payer and health 
care provider. Similarly, DMEPOS suppliers have noted that wheelchair 
repairs sometimes require prior authorization. While waiting for a 
prior authorization decision, the patient's mobility may be affected, 
which can impact their health and quality of life.
    In summary, the issues associated with prior authorization for 
laboratory tests and DMEPOS items are multifaceted, encompassing 
potential delays in patient care, administrative burden on health care 
professionals, and differing requirements across payers. Addressing 
prior authorization issues is essential to enhance the efficiency of 
health care delivery and improve patient outcomes.
2. Request for Information
    CMS is soliciting public comment on how prior authorization for 
laboratory tests and DMEPOS items impacts patient care and health care 
provider burden, and if there are opportunities to mitigate burden. CMS 
is interested in how automation of the prior authorization process for 
DMEPOS items and laboratory services could benefit health care 
providers, payers, and patients, as well as other opportunities for 
improving these processes.
     How do prior authorization requirements for laboratory 
tests and DMEPOS items currently impact patient care and health care 
provider burden?
     What are possible outcomes of more MACs, MA plans, or non-
Medicare payers allowing a TRF to be valid medical documentation to 
show that a laboratory test is reasonable and necessary?
     How frequently are prior authorizations denied because the 
request was submitted after the specimen was collected?
     What impacts have laboratory benefit managers (LBMs) had 
in facilitating prior authorization processes, regulating access, and 
controlling payment for laboratory services?
     What opportunities for process improvement exist for prior 
authorization requirements? Are changes needed to make requirements 
even more effective at containing costs, reducing burden, and improving 
patient outcomes?
     How could automation of the prior authorization process 
for laboratory tests and DMEPOS items positively affect patient 
outcomes and potentially reduce both payer and health care provider 
burden?
     What other issues exist regarding prior authorization 
processes for laboratory tests and DMEPOS items that technology is not 
currently addressing?

[[Page 20016]]

What opportunities exist for technology to mitigate those issues?
     How do the issues associated with prior authorization 
impact the health care workforce and retention of skilled health care 
professionals?

IV. Collection of Information Requirements

    Under the Paperwork Reduction Act of 1995 (hereinafter referred to 
as ``PRA'') (Pub. L. 104-13, enacted May 22, 1995), 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 (COI) 
requirement is submitted to 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.
    We request public comment on areas of this document that contain 
information collection requirements (ICRs).

A. Background

    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we included provisions which streamline the prior authorization 
process to improve patient care while increasing efficiency (89 FR 
8858). In the final rule, CMS characterized the burden associated with 
implementing the finalized APIs to support interoperability and prior 
authorization as collections of information. To more accurately 
calculate the burden in this proposed rule, the proposed policies 
included in this ICR section exclusively describe the required COI, 
while the burden and costs associated with implementation of the 
proposed policies are described in the Regulatory Impact Analysis (RIA) 
section under the Detailed Economic Analysis in section V.C. of this 
proposed rule. If finalized, the following burden estimates would be 
described in an updated version of the existing PRA package OMB control 
number 0938-1437 and submitted to OMB for approval. Further, CMS is 
pursuing additional revisions to OMB control number 0938-1437 to remove 
API implementation burden erroneously included in the original OMB 
control number 0938-1437 package. These revisions will align the 
approach for calculating ICR burden across existing interoperability 
focused PRA packages and streamline the content of the package for 
increased accuracy and fidelity to the requirements of the PRA. These 
revisions are described in section IV.D. of this proposed rule and will 
be submitted for OMB approval along with this proposed rule.

B. Wage Estimates

    To derive average costs for this proposed rule, we used data from 
the U.S. Bureau of Labor Statistics (BLS) National Occupational 
Employment and Wage Estimates and aligned our analysis with other CMS 
regulatory actions.\407\ Table 13 presents the median hourly wage, the 
cost of fringe benefits and overhead (calculated at 100 percent of 
salary), and the adjusted hourly wage. We have updated our approach and 
data sources compared to the 2024 CMS Interoperability and Prior 
Authorization final rule to create the wage table and associated 
calculations for this proposed rule. First, we used the current wages 
published on the BLS website based on 2024 data. Second, we used 
updated occupational titles and codes to reflect the current occupation 
listings. For example, the former title, ``Database Administrators and 
Architects'' with occupational code 15-1245, is now ``Database and 
Network Administrators and Architects'' with occupational code 15-1240.

Occupational Employment and Wage Estimates. Retrieved from https://data.bls.gov/oes/#/industry/000000.
---------------------------------------------------------------------------

    Additionally, per OMB's recent recommendation, we utilize the 
median hourly wages rather than mean hourly wages in our calculations 
of labor burden.
BILLING CODE 4150-28-P
[GRAPHIC] [TIFF OMITTED] TP14AP26.294

    We adjusted the employee hourly wage estimates by 100 percent, 
doubling the BLS wage estimates, to estimate fringe benefit costs. This 
calculation is a rough adjustment because fringe benefits and overhead 
costs vary significantly across employers based on the age of 
employees, location, years of employment, education, vocations, and 
other factors.

C. Information Collection Requirements

    Consistent with our approach in the 2020 CMS Interoperability and 
Patient Access and 2024 CMS Interoperability and Prior Authorization 
final rules, we determine ICRs by evaluating cost and

[[Page 20017]]

burden at the payer level (85 FR 25606 and 89 FR 8947). Since the 
previous CMS interoperability final rules, we have continued to develop 
improvements to our methodology for estimating and describing the 
reporting burden imposed on impacted payers. To determine the number of 
impacted payers (also referred to as ``parent organizations'' \408\ 
offering impacted health plans'' in the calculations) for each of the 
information collections in this proposed rule, we used information from 
three official government resources: (1) the 2024 Medicare Advantage 
Contract Directory to determine the number of parent organizations 
offering MA plans; \409\ (2) the Medicaid Managed Care Enrollment 
Report based on 2021 data to determine the number of parent 
organizations offering Medicaid managed care plans and CHIP managed 
care plans; \410\ and (3) the plan year 2024 QHP Landscape Medical 
Individual Market file to determine the number of parent organizations 
offering QHPs on the FFEs.\411\ These datasets, plus the 56 states and 
territories (hereinafter referred to as ``states'') offering Medicaid 
and CHIP FFS programs, formed the basis for the number of parent 
organizations offering impacted health plans used in our 
calculations.\412\ Plan types not affected by this proposed rule, such 
as PACE organizations, Behavioral Health Organizations (BHOs) in 
Medicaid, and QHPs offered only on SBEs or SBE-FPs, were not included 
in the counts of parent organizations offering impacted health plans. 
The three applicable datasets were merged into one list of unique 
parent organizations, mapped to the type of health plans each parent 
organization offers.
---------------------------------------------------------------------------

    \408\ A parent organization, also known as a parent company or

interest in another company, giving it control of its operations. 
Specifically, a parent organization is any corporation (other than 
the employer corporation) in an unbroken chain of corporations 
ending with the employer corporation if, at the time of granting of 
the option, each of the corporation's other employer corporation 
owns stock possessing 50 percent or more of the total combined 
voting power of all classes of stock in one of the other 
corporations in such chain (see 26 U.S.C. 424(e)).

BILLING CODE 4150-28-C
    The numbers in Table 14 are used to calculate the cost of 
compliance across all impacted payers. The estimated burden and costs 
for each ICR are included at the end of this section in Table 20.
    We have estimated that the total number of burden hours across 
impacted payers is 218,922 hours. The estimated total cost associated 
with information collection burden is $17.25 million in the second year 
following finalization and $4.32 million in subsequent years. All 
estimates will be described in the revised PRA package, OMB control 
number 0938-1437, which encompasses the information collections for all 
CMS interoperability rules--including the proposals outlined in this 
proposed rule, the 2020 CMS Interoperability and Patient Access final 
rule, and the 2024 CMS Interoperability and Prior Authorization final 
rule (85 FR 25510 and 89 FR 8758).
1. Information Collection Requirements Regarding Proposed Public 
Reporting of Prior Authorization Metrics for Drugs by Impacted Payers 
(42 CFR 422.122, 42 CFR 440.230, 42 CFR 438.210, 42 CFR 457.732, 42 CFR 
457.1230, and 45 CFR 156.223)
    To increase transparency into payer prior authorization processes 
and to assist patients in choosing health coverage and evaluating payer 
networks, we propose to require MA organizations, state Medicaid and 
CHIP FFS programs, Medicaid managed care plans, CHIP managed care 
entities, and QHP issuers on the FFEs to publicly report specific prior 
authorization metrics for drugs on their websites. We propose that MA 
organizations would report at the contract level (applicable integrated 
plans would also report drugs covered by MA organizations at the MA 
contract level), state Medicaid and CHIP FFS programs would report at 
the state level, Medicaid managed care plans and CHIP managed care 
entities would report at the plan and program level (if drug coverage 
is included in their contract), and QHP issuers on the FFEs would 
report at the issuer level. We propose that MA organizations, state 
Medicaid and CHIP FFS programs, and QHP issuers on the FFEs would be 
required to report data annually for the previous calendar year no 
later than March 31, following any calendar year that the payer offers 
that type of plan. For MA organizations, reporting would include prior 
authorizations for all

[[Page 20018]]

drugs payable under Part B, and would exclude covered Part D drugs, and 
for state Medicaid and CHIP FFS programs and QHP issuers on the FFEs, 
data would include all drugs requiring prior authorization. We are 
proposing to require those impacted payers to publish these reports 
beginning March 31, 2028. We are also proposing to require Medicaid 
managed care plans and CHIP managed care entities to report data 
annually no later than 90 days after the end of their rating period. 
For Medicaid managed care plans and CHIP managed care entities, reports 
would include prior authorizations for all drugs.
    To comply with reporting requirements, we estimate that impacted 
payers would conduct two major work phases: (1) development, which 
includes defining requirements; and (2) maintenance, including an 
annual compilation of reports and public reporting of metrics on a 
website. In the first phase, impacted payers would need to define 
requirements concerning the types and sources of data that must be 
compiled regarding prior authorization activities for drugs and then 
compile the database to capture this information. In the second phase, 
impacted payers must create and post the reports to a public website 
annually.
    Table 15 itemizes the estimated activities, hours, and dollar 
burdens for the first-year implementation and estimated annual 
maintenance costs. We assume relevant staff would include a software 
and web developer with a business operations specialist.
     First-year implementation would impose a total burden of 
320 hours for the first year and 120 hours for subsequent years, at a 
per-entity cost of $33,300 and $9,400 (rounded) for the first and 
subsequent years, respectively.
     The aggregate burden of the first-year implementation 
across all 341 impacted payers included in this proposal is 109,000 
hours and 41,000 hours (rounded) for the first and subsequent years, 
respectively, at a cost of $11.36 million and $3.20 million (rounded).

2. Information Collection Requirements for Proposed Reporting of 
Provider Access, Payer-to-Payer, and Prior Authorization API Metrics to 
CMS by Impacted Payers (42 CFR 422.121, 42 CFR 422.122, 42 CFR 431.61, 
42 CFR 431.80, 42 CFR 438.242, 42 CFR 457.731, 42 CFR 457.732, 42 CFR 
457.1233, 45 CFR 156.222, and 45 CFR 156.223)
    Beginning in 2026, CMS will begin collecting data from impacted 
payers on Patient Access API usage. As well as the finalized Patient 
Access API usage metrics, we are proposing to require, beginning in 
2028, impacted payers to report metrics to CMS in the form of 
aggregated, de-identified data about Provider Access, Payer-to-Payer, 
and Prior Authorization API usage. We propose that impacted payers 
would be required to annually report these data to CMS on dates 
appropriate to each payer's regular reporting, contracting, or 
certification periods, as described earlier in this proposed rule.
    We believe these data could provide insight into provider and payer 
use of the new APIs, the effectiveness of the CMS policies, and any 
additional education and outreach in which CMS may need to engage. The 
annual reports would be submitted to CMS by impacted payers. 
Specifically, we propose collecting the metrics outlined in section 
II.F.2. of this proposed rule for the Provider Access, Payer-to-Payer, 
and Prior Authorization APIs. For such reporting efforts, we estimate 
that the impacted payers would conduct a gap analysis of existing 
reports they may have already prepared, followed by appropriate tasks 
to develop, produce, and submit such reports to CMS for the metrics 
outlined in section II.F.2. of this proposed rule.
    Table 16 includes our estimates for first-year implementation and 
ongoing reporting tasks. Total staffing hours would be 160 and 40 hours 
for the first and subsequent years, respectively, at a total cost per 
impacted payer of $17,000 and $3,000 (rounded). The aggregate burden 
for 341 parent organizations would be 55,000 hours and 14,000 hours 
(rounded) for the first and subsequent years at a cost of $5.84 million 
and $1.07 million (rounded), respectively.

3. Information Collection Requirements for Proposed Reporting of Payer 
API Endpoints (42 CFR 422.119, 42 CFR 422.120, 42 CFR 422.121, 42 CFR 
422.122, 42 CFR 431.60, 42 CFR 431.61, 42 CFR 431.70, 42 CFR 431.80, 42 
CFR 438.242, 42 CFR 457.730, 42 CFR 457.731, 42 CFR 457.732, 42 CFR 
457.760, 42 CFR 457.1233, 45 CFR 156.221, 45 CFR 156.222, and 45 CFR 
156.223)
    No later than 60 days after the effective date of the final rule, 
CMS would require impacted payers to report API endpoints to CMS for 
publication in the form of an Endpoint Resource, as defined by an 
unexpired version of the FHIR[supreg] standard adopted in 45 CFR 
170.215(a). New impacted payers would be required to report this 
information no later than 60 days before they begin covering patients 
under the applicable CMS program. Further, CMS proposes to require 
impacted payers to report to CMS the direct URL for their 
interoperability API's FHIR capability statements and one or more URLs 
with the required documentation regarding authorization and 
authentication protocol and implementation details and API registration 
information. CMS would require impacted payers to report updated 
information within 1 week of any changes to the reported information 
and verify the reported information at least every 12 months. The 
proposed policy would require 2 hours of labor by a Business Operations 
Specialist at an hourly rate of $78.14 or $156.28 annually. For all 
impacted payers, this reporting burden would be $53,291 annually, 
rounded ($156.28 x 341 respondents = $53,291.48).

D. Modifications to Existing OMB Control Number 0938-1437

    The existing OMB control number 0938-1437 describes the burden 
associated with the policies finalized in the 2024 CMS Interoperability 
and Prior Authorization final rule (89 FR 8758). As mentioned 
previously in this section, CMS seeks to streamline PRA packages 
corresponding to the CMS interoperability rules.
1. API Implementation Burden
    OMB control number 0938-1437 currently includes the burden 
associated with API implementation requirements finalized in the 2024 
CMS Interoperability and Prior Authorization final rule (89 FR 8858). 
CMS intends to modify the PRA package to remove the implementation 
burden of the API policies, as they do not reflect information 
collection burden as defined by the PRA and falsely inflate the 
information collection burden associated with the PRA package and the 
2024 CMS Interoperability and Prior Authorization final rule. 
Specifically, we are removing the burden estimates associated with 
developing, implementing, and maintaining the APIs finalized in the 
2024 CMS Interoperability and Prior Authorization final rule and usual 
and customary business costs related to prior authorization process 
requirements, while retaining the following burden estimates: (1) 
reporting Patient Access API metrics to CMS (42 CFR 422.119, 42 CFR 
431.60, 42 CFR 438.242, 42 CFR 457.730, and 42 CFR 457.1233 and 45 CFR 
156.221); and (2) publicly reporting prior authorization metrics (42 
CFR 422.122, 42 CFR 438.210, 42 CFR 440.230, 42 CFR 457.732, and 42 CFR 
457.1230 and 45 CFR 156.223).
    CMS originally calculated the PRA burden by including the cost of 
finalized requirements to implement and maintain the Provider Access, 
Payer-to-Payer, and Prior Authorization APIs. We assumed that to 
implement these APIs, impacted payers would conduct three major work 
phases: initial design, development and testing, and long-term support 
and maintenance and accounted for these costs in the PRA package, thus 
inflating the estimated burden with costs not associated with COI. When 
updating OMB control number 0938-1437 to reflect the burden associated 
with this proposed rule, CMS will remove the following costs as 
outlined in Table 18.

[[Page 20020]]

[GRAPHIC] [TIFF OMITTED] TP14AP26.299

    This modification would reduce the calculated information 
collection cost burden by $684 million and by 6,659,425 burden hours.
2. Prior Authorization Decision Timeframe Requirement Burden
    In the 2024 CMS Interoperability and Prior Authorization final 
rule, CMS established timeframe requirements for impacted payers to 
provide prior authorization decisions (89 FR 8897). In the ICR section 
of the 2024 CMS Interoperability and Prior Authorization final rule, 
CMS described the final policy as imposing information collection 
burden on the impacted payers in the form of up-front costs for 
impacted payers to update their policies and procedures (89 FR 8952). 
We estimated that this policy would result in 8 hours of work by a 
general and operations manager to update the policies and procedures, 
reflecting 2 half-days of work at a per-entity cost of $967. Therefore, 
the total burden for all 365 impacted payers is 2,920 hours of work at 
a cost of $0.35 million. However, the cost of updating internal 
policies and procedures by a payer is considered by CMS to be usual and 
customary and does not necessitate an ICR or corresponding burden in a 
PRA package. CMS intended to characterize this burden as usual and 
customary, which is reflected in the supporting statement for the 
currently approved PRA package, but due to a technical error the burden 
was included in the total cost of the rule and in the burden total of 
the PRA package. To correct this oversight and to avoid falsely 
inflating the estimated burden with costs not associated with COI, CMS 
would remove these costs when updating OMB control number 0938-1437, as 
outlined in Table 19.
[GRAPHIC] [TIFF OMITTED] TP14AP26.300

    This modification would reduce the calculated burden by $0.35 
million. In combination, the revisions described in Tables 18 and 19 
would reduce the calculated burden from the PRA package approved under 
OMB control number 0938-1437 by $684.35 million.

E. Summary of Information Collection Burdens

    In this section we have explained the estimated costs of individual 
proposals for purposes of the ICRs. Table 20 summarizes costs for the 
first and subsequent years of these proposals and is based on the 
following assumptions:
     Certain proposals would be effective beginning 2028. 
However, we assume impacted payers would conduct certain activities 
before the compliance date to make appropriate operational, procedural, 
or system changes.
     We are basing our calculations on a 1 year estimate to 
accommodate all system, process, and reporting activities. The 1 year 
reflects the period from the expected publication of a proposed rule in 
[Placeholder Date] until the associated compliance dates.
     Labor costs in the COI are either BLS wages when a single 
staff member is involved or a weighted average representing a team 
effort, obtained by dividing the aggregate cost by the aggregate hours.
     Note that while the ICR burden calculations in Table H8 
reflect differing amounts of burden in the first and subsequent 
implementation years, CMS will submit the revised OMB control number 
0938-1437 to reflect the average annual burden amount across the first, 
second, and third implementation year, to align with the 3-year PRA 
package expiration timeframe. Table 20 provides the 3-year averages in 
columns ``Average Annual Hours'' and ``Average Annual Cost.''

BILLING CODE 4150-28-C

F. Conclusion

    The proposals in this proposed rule, if finalized, should lead to 
phased improvements of sharing data across impacted payers and 
providers by requiring systems that facilitate patient data access, 
receipt, and exchange. We request comments on our approaches for 
estimating cost burden.
    We have submitted a copy of this proposed rule to OMB for its 
review of the rule's information and recordkeeping requirements. These 
requirements are not effective until they have been approved by OMB. To 
obtain copies of the supporting statement and any related forms for the 
proposed collections discussed previously, please visit CMS's website 
at https://www.cms.gov/Regulations-andGuidance/Legislation/PaperworkReductionActof1995/PRAListing.html or call the Report 
Clearance Office at 410-786-1326.

V. Regulatory Impact Analysis

A. Statement of Need

    If finalized, the proposals in this proposed rule would place new 
requirements on MA organizations, state Medicaid and CHIP FFS programs, 
Medicaid managed care plans, CHIP managed care entities, and QHP 
issuers on the FFEs (collectively referred to as ``impacted payers'') 
\413\ to enhance the electronic exchange of health care-related data 
and improve the prior authorization process for drugs by establishing 
technology standards and process requirements. We are proposing to 
require these payers to publish an enhanced set of metrics related to 
the prior authorization process and to report to CMS their digital 
endpoints to facilitate the electronic exchange of information. 
Finally, HHS is proposing to modernize the HIPAA prior authorization 
transaction standard by replacing the existing X12N transaction 
standards with FHIR[supreg] based standards. We believe these changes 
(proposed in 42 CFR parts 422, 431, 438, 440, and 457 and 45 CFR part 
156) support CMS's efforts to reduce burden on providers while enabling 
them to spend more time with their patients. Additionally, HHS believes 
that these changes (proposed in 45 CFR part 162) would improve prior 
authorization transactions for all HIPAA covered entities. These 
proposals should increase electronic access to health care data while 
keeping that information safe and secure. The proposals build on the 
foundation laid out in the 2020 CMS Interoperability and Patient Access 
and the 2024 CMS Interoperability and Prior Authorization final rules 
to move the health care system toward increased interoperability by 
enhancing impacted payers' ability to share data, encouraging health 
care providers to use new capabilities, and making health-related data 
more easily available to patients through health apps.
---------------------------------------------------------------------------

    \413\ We provide a detailed rationale for how we determined the 
number of impacted payers in the CMS Interoperability and Patient 
Access final rule (85 FR 25622-25623). In that analysis we 
determined that 288 issuers and 56 states, territories, and U.S. 
commonwealths, which operate state Medicaid and CHIP FFS programs, 
will be subject to the API provisions for Medicare, Medicaid, and 
the individual market. To this, we added the one state that operates 
its CHIP and Medicaid separately. Thus, we have 345 total impacted 
payers (288 + 56 + 1). This number has been updated to 341 to 
reflect a consolidation of impacted payers in the impacted programs.
---------------------------------------------------------------------------

B. Overall Impact

    We are required by Executive Order 12866 on Regulatory Planning and 
Review (September 30, 1993), Executive Order 13563 on Improving 
Regulation and Regulatory Review (January 18, 2011), Executive Order 
14192 on Unleashing Prosperity Through Deregulation (January 31, 2025), 
the Regulatory Flexibility Act (RFA) (September 19, 1980, Pub. L. 96-
354), Executive Order 13272 on Proper Consideration of Small Entities 
in Agency Rulemaking (August 13, 2002), section 1102(b) of the Act, 
section 202 of the Unfunded Mandates Reform Act of 1995 (UMRA) (March 
22, 1995, Pub. L. 104-4), and Executive Order 13132 on Federalism 
(August 4, 1999) to examine the impacts of a proposed rule.
    Executive Orders 12866 and 13563 direct agencies to assess all 
costs and benefits of available regulatory alternatives and, if 
regulation is necessary, to select regulatory approaches that maximize 
net benefits (including potential economic, environmental, public 
health, safety effects, and distributive impacts). 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.
    Based on our estimates, the Office of Information and Regulatory 
Affairs (OIRA) has determined this proposed rulemaking to be 
significant per section 3(f)(1) of Executive Order 12866, as the 
initial economic impact estimates presented in this proposed rule 
approach the $100 million threshold. We have prepared a RIA that 
presents the estimated costs, benefits, and transfers of this proposed 
rule. We note that the proposed rule impacts two overlapping but 
regulatorily distinct groups of entities: impacted payers (MA 
organizations, state Medicaid and CHIP FFS programs, Medicaid managed 
care plans, CHIP managed care entities, and QHP issuers on the FFEs) 
which are health plans regulated by CMS; and HIPAA covered entities, 
which are regulated by HHS, and defined as ``a health plan, health care 
clearing house, a health care provider who transmits any health 
information in electronic form in connection with a transaction covered 
by this subchapter.'' \414\ We note that all impacted payers are health 
plans and therefore are HIPAA covered entities, but not all HIPAA 
covered entities are impacted payers since the scope of this category 
is more broad and encompasses many sectors of the health care industry. 
To disentangle these two overlapping categories and clearly present the 
anticipated cost associated with each policy, we divide the Cost 
section V.C.2. of this proposed rule, and the Initial Regulatory 
Flexibility Analysis (IRFA) sections V.F.2. and V.F.3. of this proposed 
rule into subsections that describe HHS proposals related to HIPAA 
covered entities and separately describe CMS proposals for impacted 
payers. In section V.C.2.a.(1). of this proposed rule describing the 
HIPAA cost estimates, we attempt to isolate the HIPAA covered entities 
that are also impacted payers such that they are not double counted in 
the burden estimates associated with adopting FHIR. Some of the 
proposals in this proposed rule have information collection related 
burdens, and the cost associated with those ICRs is provided in Table 
20 in section IV.E. of this proposed rule. Table 25, Cost of the 
Proposed Rule to Impacted Payers by Year and Program, provides a 
summary of the cost of CMS proposals on impacted payers, broken out by 
payer program and calendar year. Table 32, Cost of the Proposed Rule to 
the Federal Government by Year and Program, provides a summary of the 
estimated costs to the federal government by payer

[[Page 20023]]

program and calendar year. Specifically, this table reflects the cost 
of CMS proposals incurred by payers in federally funded programs and 
identifies the portion of that cost which would be covered by payments 
from the federal government. Finally, Table 33, Total Cost of Proposed 
Policies by Year, summarizes the cost of the entire proposed rule by 
describing the cost of each proposed provision over the next 10 years 
(including the ICR costs described in Table 20).

    \414\ See 45 CFR 160.103.
---------------------------------------------------------------------------

C. Detailed Economic Analysis

1. Benefits
    Anticipated non-quantified benefits of this proposed rule relate to 
improving continuity of care and patient outcomes. Prescription and 
other drug information is part of a patient's record and giving 
patients, providers, and payers access to claims data for prescription 
and other drugs can offer valuable insights into a patient's health 
care, provide benefits for care coordination, and avoid potentially 
harmful drug interactions. The proposal to incorporate drugs into the 
existing prior authorization API requirements has the potential to 
improve the timeliness of prior authorization decisions for drugs and 
minimize prior authorization denials, which could reduce delays in 
patient access to medication and limit the associated medical risk. The 
proposal to align state CHIP FFS programs' and QHP issuers on the FFEs' 
deadlines for responses to prior authorization requests with other 
impacted payers would likely result in operational efficiencies across 
a health plan's multiple lines of business, as there would be a 
consistent expectation and policy across the different products offered 
by that plan. Further, the proposals to report prior authorization 
metrics could benefit patients by allowing them to make better informed 
decisions regarding their plan selection.
    We believe that many stakeholders could benefit from the proposals 
in this proposed rule, but do not provide an analysis of expected 
savings to impacted payers and HIPAA covered entities arising from 
proposed prior authorization process improvements, use of NCPDP 
standards, or updates to replace current X12N transaction standards 
with the FHIR standard and applicable IGs for electronic prior 
authorization transactions. The estimated savings associated with 
utilizing APIs to exchange EHI is already described in detail in the 
2024 CMS Interoperability and Prior Authorization final rule. The 
proposals in this proposed rule build upon those finalized requirements 
by expanding the type of information exchanged, but they do not produce 
the same level of quantifiable efficiencies as those created by the 
requirements to transition from manual prior authorization processes to 
electronic prior authorization via an API. While we do not make 
specific assumptions about savings, we believe there could be cost-
reducing benefits associated with these provisions including reduced 
paperwork, faster response times, and other efficiencies.\415\
---------------------------------------------------------------------------

    \415\ See the 2024 CMS Interoperability and Prior Authorization 
final rule for detailed discussion on how API availability would 
yield efficiency benefits for providers and impacted payer (89 FR 
8758).
---------------------------------------------------------------------------

    Surveys by the AMA cited in section II.C. of this proposed rule 
describe negative consequences of delayed prior authorizations, 
including those for drugs, and stakeholders wrote about the challenges 
of complicated payer requirements for prior authorization of drugs and 
delayed decision-making. However, we have not received specific 
financial information from commenters or industry surveys. Nonetheless, 
we believe savings would accrue due to fewer denials and fewer appeals 
that would need to be processed by impacted payers because of these 
proposals. Denials and appeals sometimes result from errors, missing 
information, lack of specificity or clarity in guidelines or 
instructions. We believe that by requiring impacted payers to 
incorporate coverage and documentation requirements for drugs covered 
under a medical benefit into the Prior Authorization API, as well as to 
support the proposed NCPDP standards for electronic prior authorization 
of drugs covered under a pharmacy benefit, providers would be better 
able to collect and submit all necessary information to conduct a prior 
authorization, which could reduce processing challenges and increase 
efficiencies, resulting in cost savings. Further, HHS expects that the 
proposal to adopt FHIR standards for HIPAA covered entities (health 
care providers, health plans, and health care clearinghouses) to 
conduct electronic prior authorization transactions could reduce 
processing challenges, produce administrative efficiencies, and create 
savings long-term.
2. Costs
a. Rulemaking Costs Related to HHS Proposals
(1) Costs Associated With the Proposal To Adopt FHIR Standards for 
Electronic Prior Authorization-Related HIPAA-Standard Transactions (45 
CFR 162.103, 45 CFR 162.1202, 45 CFR 162.1203, and 45 CFR 162.1302)
    HHS is proposing a modification to two HIPAA Administrative 
Simplification transactions, the ``referral certification and 
authorization'' transaction in 45 CFR part 162, subpart M, and the 
``eligibility for a health plan'' transaction in 45 CFR part 162, 
subpart L. Specifically, HHS proposes adding a new paragraph in 45 CFR 
162.1302(g) to adopt the FHIR standard and the US Core, SMART App 
Launch, CRD, DTR, PAS, and CDex IGs as the specifications that compose 
the proposed transaction standard for dental, professional, and 
institutional ``referral certifications and authorization'' 
transactions. In addition, in a new paragraph in 45 CFR 162.1202(f)(2), 
HHS is proposing to adopt the FHIR standard, the US Core, SMART App 
Launch, and CRD IGs as the specifications that compose the proposed 
transaction standard for dental, professional, and institutional 
``eligibility for a health plan'' transactions, when used to determine 
whether prior authorization is required. If finalized as proposed, 
HIPAA covered entities would be required to comply with these 
transaction standards no later than 24 months from the effective date 
of a final rule, except for small health plans, for which the 
compliance date would be 36 months from the effective date of a final 
rule.
    The costs associated with the proposal to adopt FHIR standards 
differ from the other costs described in this proposed rule because the 
number of HIPAA covered entities is much larger than the number of 
impacted payers regulated by CMS and includes various types of business 
entities across the health care industry. For the purposes of this 
impact analysis, HHS assumes that only the HIPAA covered entities that 
have not yet implemented FHIR standards or do not use certified health 
IT that includes FHIR would incur cost for the technical work of 
updating systems from the current X12N 278 transaction standard to 
implement the proposed FHIR standards for electronic prior 
authorization. Though the data are severely limited, HHS attempts to 
provide reasonable estimates of the number of HIPAA covered entities 
that already utilize FHIR APIs, or that are already required to 
implement FHIR

[[Page 20024]]

APIs per the finalized policies in the 2024 CMS Interoperability and 
Prior Authorization final rule (89 FR 8758), and exclude them from the 
estimated cost. HHS assumes the cost and effort of updating health IT 
systems from using the current X12N 278 transaction standard to FHIR 
would vary depending on the type of HIPAA covered entity, so HHS 
separately examines the burden of FHIR standards adoption amongst 
health plans and health care providers (including hospitals, clinics, 
and individual providers). HHS documents uncertainties related to the 
impact of transitioning to FHIR amongst EHR or other health IT vendors 
and health care clearinghouses.
    For these estimates, HHS uses the adoption of certified EHR 
technology as a proxy for FHIR API adoption. The ONC Cures Act final 
rule adopted an API certification criterion which requires the use of 
the HL7 FHIR standard and incorporated this criterion into the 2015 
Edition Base EHR definition (85 FR 25646). Therefore, HHS assumes that 
the use of certified health IT among certain HIPAA covered entities 
corresponds to the use of and access to FHIR standards and relies on 
industry data and research into the use of certified EHR technology. 
HHS concludes that if a HIPAA covered entity, such as a hospital, 
relies on the X12N transaction standards for prior authorization, but 
is already using FHIR-enabled certified EHR technology in their 
workflow, then they would incur negligible cost in complying with the 
proposed requirements to transition to the FHIR standard since they 
already have technology with the technical capability in place.
    HHS uses many of the assumptions and data sources leveraged in the 
2022 HIPAA Standards for Health Care Attachments proposed rule to 
estimate the number of HIPAA covered entities that would be impacted by 
the proposed requirements (87 FR 78438). As in the 2022 HIPAA Standards 
for Health Care Attachments proposed rule, HHS used the Census Bureau 
2022 Statistics of U.S. Businesses (SUSB) dataset (which is based on 
the 2017 North American Industry Classification System [NAICS] codes) 
to identify NAICS codes corresponding to hospitals, health care 
providers (using physician NAICS code), and health plans to determine 
the total count of firms within each category of impacted HIPAA covered 
entities, which are listed in Table 21.\416\ HHS utilizes the NAICS 
code for ``Office Physicians'' to analyze the potential cost to this 
subset of HIPAA covered entity rather than include every type of 
physician in this analysis. The data reflect that other types of 
office-based providers (for example, mental health specialists, 
chiropractors, and dentists) have lower adoption of the X12N 278 
transaction standard and certified EHR in their practice to varying 
degrees. For the purposes of this analysis, HHS concluded that office 
physicians were the providers who were most likely to be impacted by 
these proposed requirements, and that HHS would focus on this NAICS 
category.

(a) Hospitals
    The Census Bureau 2022 SUSB dataset reflects 3,319 hospital firms 
nationwide. Of these 3,319 firms, approximately 2,573 are general 
hospitals, 419 are psychiatric hospitals, and 327 are specialty 
hospitals. According to an analysis on the adoption of EHRs by hospital 
service type from 2019 through 2021 published by ONC, approximately 96 
percent of all non-federal acute care hospitals adopted a certified 
EHR, while 40 percent of rehabilitation hospitals and 23 percent of 
specialty hospitals adopted a 2015 Edition certified EHR 
technology.\417\ By applying these percentages to the subcategories of 
hospital described in the Census Bureau 2022 SUSB, HHS estimates that 
2,713 hospital firms are already using certified EHR technology enabled 
with FHIR. In 2021, ONC published retrospective analysis on their 
research from 2018, which reflected on the estimated potential adoption 
of 2015 Edition certified EHR technology enabled with FHIR compared to 
the actual adoption they observed in 2019.\418\ In addition to those

hospitals and clinicians that adopted technology in 2019, the data 
suggest that another 7 percent of hospitals could upgrade to 2015 
Edition certified EHR technology enabled with FHIR from their current 
health IT developer.\419\ HHS uses 7 percent from this analysis to 
estimate the number of hospital firms that could adopt the FHIR 
standard by upgrading to certified EHR technology enabled with FHIR, 
offered by their current EHR vendor. Of the remaining 606 hospital 
firms, HHS assumes that 7 percent, or 42 firms, (606 x 0.07 = 42.42) 
would upgrade their EHR product to certified EHR technology to adopt 
FHIR standards required by this proposal and may incur cost associated 
with upgrading their EHR product. Based on industry research, HHS 
estimates the one-time cost of upgrading an EHR product to be 
approximately $10,000, not including the recurring annual maintenance 
fees or monthly per-user fees.\420\ Therefore, HHS expects these 42 
hospitals to incur approximately $424,277 in one-time costs (42.42 x 
10,000 = $424,277). HHS is uncertain what the remaining population of 
hospital firms would do to remain compliant with the proposed 
requirements, if finalized. To avoid conducting many divergent analyses 
and implying a false sense of precision, HHS assumes that the 
approximately 563 hospital firms that do not have access to certified 
EHR technology through their current EHR vendor would not attempt to 
undergo the costly process of switching to a different EHR vendor. 
Industry research indicates that switching EHR vendors takes multiple 
years of preparation and can cost at minimum $500,000 for 
hospitals.421 422 These hospitals may be smaller or have 
less resources available, and HHS assumes that they would continue to 
rely on manual processes to complete electronic prior authorization 
transactions and/or wait for their current EHR vendor to offer a 
certified technology product that is FHIR enabled.

(b) Physicians
    Analysis conducted by ONC suggests that, as of 2021, approximately 
78 percent of physicians adopted and utilize certified EHR technology 
in their practice.\423\ An earlier analysis conducted on 2019 data 
indicates that while 61 percent of clinicians adopted certified EHR 
technology, 11 percent of clinicians that did not adopt certified EHR 
could have done so by upgrading to 2015 Edition certified EHR 
technology enabled with FHIR from their current health IT 
developer.\424\ Absent more recent data on the population of physicians 
who could adopt certified EHR technology, HHS uses the ratio of ``could 
adopt but did not adopt'' to ``did not adopt'' from the 2019 data 
analysis and applies it to the more recent 2021 statistics (11/39 = X/
22, X = 6.21). This yields an estimated 6 percent of clinicians that 
could adopt EHR technology. The Census Bureau 2022 SUSB dataset 
reflects 145,305 physician firms nationwide.\425\ For these estimates, 
HHS assumes that approximately 113,338 physician firms (145,305 x 0.78 
= 113,337.90) already use certified EHR technology. Of the remaining 
approximately 31,967 physician firms, HHS assumes 6 percent, or 
approximately 1,985 (31,967.10 x 0.0621 = 1,985.16), would upgrade to a 
certified EHR product based on HHS's proposals to modify the current 
X12N 270/271 and 278 transaction standards to FHIR standards for 
transactions related to prior authorization, as HHS is proposing to 
define that term. HHS assumes a one-time cost of $10,000, same as the 
cost estimate for hospital firms, to upgrade products, resulting in 
approximately $19,851,569 among these physician firms (1,985.16 x 
$10,000 = $19,851,569.10). Under this assumption, HHS is left with 
29,982 physician firms (31,967-1,985.16 = 29,981.84) that do not 
currently have access to FHIR-enabled certified EHR technology. As with 
hospital firms, HHS is uncertain what the remaining population of 
physician firms might do to remain in compliance with the new 
requirements. To avoid conducting many divergent analyses and implying 
a false sense of precision, HHS assumes that these remaining 29,982 
physician firms without any access to FHIR would not implement FHIR-
enabled software. In the absence of reliable data on FHIR utilization 
rates among physicians, HHS believes this assumption to be reasonable, 
especially due to the costly nature of the process, which can range 
from $50,000 to $100,000 depending on the number of system users in the 
physician's office.426 427 428

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

(c) Health Plans
    The Census Bureau 2022 SUSB dataset reflects 1,071 health plan 
firms nationwide.\429\ In estimating the number of health plans that 
would incur new cost due to the proposed HIPAA transaction standard 
requirements, HHS takes into account 341 parent organizations which 
represent impacted payers subject to the requirements established in 
the 2024 CMS Interoperability and Prior Authorization final rule.\430\ 
The definition of NAICS ``firms'' is approximate to the definition of 
``parent organization'' that CMS used to calculate the number of 
impacted payers in the 2024 CMS Interoperability and Prior 
Authorization final rule.\431\ HHS assumes that the 341 parent 
organizations would incur negligible cost to transition from current 
X12N 270/271 and 278 transaction standards and implement the proposed 
FHIR standards for prior authorizations, as they are already required 
to implement

[[Page 20026]]

FHIR standards for prior authorization by the 2024 CMS Interoperability 
and Prior Authorization final rule. Therefore, HHS deducts the 341 
parent organizations previously accounted for from the count of health 
plan firms and estimates that 730 health plan firms have not adopted 
FHIR standards or are not required to do so in regulation or both 
(1,071-341 = 730).
---------------------------------------------------------------------------

    \429\ United States Census Bureau. (2025, April). 2022 SUSB 
Annual Data Tables by Establishment Industry. Retrieved from https://www.census.gov/data/tables/2022/econ/susb/2022-susb-annual.html.
    \430\ These impacted payers include MA organizations, state 
Medicaid and CHIP FFS programs, Medicaid managed care plans, CHIP 
managed care entities, and QHP issuers on the FFEs.
    \431\ See the 2020 CMS Interoperability and Patient Access final 
rule (85 FR 25623) for information on the methodology used to define 
and identify parent organizations.
---------------------------------------------------------------------------

    HHS does not anticipate a one hundred percent transition to the 
proposed FHIR standards for electronic prior authorization transactions 
among the remaining 730 health plan firms. Since the adoption of X12N 
transaction standards among health plans for prior authorizations 
remains low (approximately 35 percent), HHS expects that some health 
plans which have not yet adopted the X12N transaction standards for 
prior authorizations will forego the investment in a FHIR API and 
instead continue to use manual prior authorization methods or 
proprietary portals.\432\ Therefore, HHS estimates that of the 
remaining 730 health insurance firms, approximately 35 percent, or 256 
(730 x 0.35 = 255.50 rounded), would update their system from current 
X12N transaction standards to the proposed FHIR API standards for prior 
authorization. These 256 health plans may incur cost associated with 
building and implementing FHIR APIs for the first time. HHS 
acknowledges that this methodology to estimate the number of health 
plans with experience implementing FHIR APIs does not account for the 
many commercial health plans that are already leveraging FHIR standards 
in their workflows or other business functions but are not captured in 
the population of impacted payers or certified EHR adopters. Due to the 
lack of data on the use of FHIR industry-wide, HHS presents this 
estimate and requests comment on these assumptions.

CAQH Index Report. Retrieved from https://www.caqh.org/hubfs/Index/2024%20Index%20Report/CAQH_IndexReport_2024_FINAL.pdf.
---------------------------------------------------------------------------

    HHS estimates that the cost of implementing and maintaining a FHIR 
API using the proposed FHIR standards would largely align with the cost 
to implement and maintain the Prior Authorization APIs described in the 
2024 CMS Interoperability and Prior Authorization final rule. Health 
plans would conduct three work phases: (1) design; (2) development and 
testing; and (3) support and maintenance (85 FR 25605 and 25623, and 89 
FR 8948, 8950, and 8953). In the initial design phase, tasks include 
determining available resources (for example, personnel, hardware, 
cloud storage space, etc.); assessing whether to use in-house or 
contracted resources to facilitate an API connection; convening a team 
to scope, build, test, and maintain the API; gap analysis; and gap 
mitigation. During the development and testing phase, health plans 
would map existing data to the FHIR standards, determine hardware 
allocation for the necessary environments (development, testing, and 
production), build a new FHIR server, determine the frequency and 
method by which internal data are populated on the FHIR server, build 
connections between the databases and the FHIR server, perform 
capability and security testing, and vet provider requests.
    HHS further refines these technical builds and implementation 
estimates by considering the results of industry exceptions testing 
requested by the HL7[supreg] Da Vinci Project (HL7 FHIR Exception 
#202103100) to test FHIR standards.\433\ The testing exceptions report 
from the HL7 Da Vinci Project stated that the design, testing, and 
deployment of the FHIR API was accomplished by one health plan for 
$135,000, which is significantly less costly than the API build 
estimates included in the 2024 CMS Interoperability and Prior 
Authorization final rule (89 FR 8951). In the 2024 CMS Interoperability 
and Prior Authorization final rule, we estimated the cost of 
implementing the Prior Authorization API to range from $208.9 million 
to $626.6 million. Because the cost of the industry exceptions testing 
was significantly lower, less than half than the median of the range of 
per-entity cost estimated in the 2024 CMS Interoperability and Prior 
Authorization final rule ($417.7 million), HHS is hesitant to project 
this rate across all HIPAA covered entities, particularly health plans. 
To produce a reasonable estimate that does not drastically depart from 
the previous estimations in the 2024 CMS Interoperability and Prior 
Authorization final rule, but that does acknowledge that many health 
plans have a degree of familiarity and efficiency with FHIR development 
since the previous rulemaking as indicated by the exception testing 
project, HHS uses the low range of the hourly labor build estimates 
(reflected in Table 22 column ``Hourly Burden'') presented in the 2024 
CMS Interoperability and Prior Authorization final rule in calculating 
this burden.

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

    For the estimated 256 health plans, HHS assumes that the one-time 
cost to develop and implement the FHIR API will require approximately 
2,790 hours of labor for each entity over 2 years, at a total cost of 
approximately $327,000 dollars. See Table 22 for a breakdown of the 
total costs. HHS estimates an annual maintenance cost averaging 
approximately 25 percent of the estimated one-time API development 
costs. Total annual maintenance cost for a single health plan would be 
approximately $78,000 dollars and this cost is included in the 10-year 
projections in Table 33.

BILLING CODE 4150-28-C
(d) Uncertainties
    While HHS is of the view that the use and accessibility of FHIR-
enabled certified EHR technology in the health care industry is 
increasing, business practice uncertainties and a paucity of baseline 
data make it difficult to estimate the cost of adopting FHIR among 
certain HIPAA covered entities. In particular, the potential cost 
incurred by health care clearinghouses and EHR vendors that supply 
technologies to health care providers to adopt the proposed FHIR 
standards for prior authorization-related transactions into their 
products and contract offerings is unclear.
    EHR vendors provide the technology that many hospitals and 
physicians use to transmit EHI to and from payers. For the purposes of 
this impact analysis, HHS uses ``EHR vendor'' as a catch-all to 
represent plan management system vendors and EHR technology system 
vendors. Counting the affected entities separately is complicated, in 
part because they are increasingly integrated. A health care provider 
entity's plan management system and EHR systems may be bundled in one 
product offering, semi-integrated affiliated systems, or entirely 
independent systems offered by separate vendors. The 2022 Census Bureau 
SUSB dataset does not provide firm-level counts for health care 
industry-specific technology vendors.\434\ For this reason, HHS relies 
on the same data source used in the 2022 HIPAA Standards for Health 
Care Attachments proposed rule impact analysis to count EHR vendors. 
This industry reporting from 2024 and 2025 suggests that approximately 
500 vendors are offering an EHR product and that several large vendors 
dominate the EHR market.\435\ Epic, Oracle Cerner, and Meditech are the 
three biggest EHR vendors among hospitals, making up nearly 75 percent 
of the market share combined.\436\ Epic, Oracle Cerner, and 
athenahealth, Inc. represent the biggest vendors among clinicians, with 
approximately 82 percent of the market share 
combined.437 438 These vendors all offer

[[Page 20028]]

certified EHR technology products which are FHIR-enabled, though they 
are typically priced higher than basic EHR software. For vendors who 
already have FHIR-enabled EHR product offerings, it is unclear if the 
proposed requirement would spur them to develop new products at 
different price points in anticipation of an increase in hospital and 
physician demand. For EHR vendors that do not currently offer FHIR-
enabled EHR products, it is unclear if the proposed requirements would 
move them to begin developing new software. HHS assumes that these 
vendors may cater to smaller provider markets and may not be able to 
justify the costly process of software development for their client 
base.

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

    Health care clearinghouses present another set of uncertainties. 
Clearinghouses provide transaction processing and data translation 
services to both providers and health plans. The applicable NAICS 
category (NAICS 524114) includes many types of financial transaction 
processing firms other than those affected by this rule, so the Census 
business data cannot be used to identify a nationwide count. Based on 
the counts used in the 2022 HIPAA Standards for Health Care Attachments 
proposed rule, HHS assumes that there are approximately 162 
clearinghouse entities nationwide (87 FR 78455). According to industry 
research, most health care clearinghouse vendors integrate with or 
offer features that can be part of health IT systems, including EHR or 
other health IT products.\439\ A few of their main features include 
claim submission, payment posting, and denial management, though 
increasingly, EHR vendors are offering those same features and services 
to clients either independently or by contracting with a clearinghouse. 
Prior authorization is not one of the main workflows associated with 
clearinghouse services, but it does come into play for certain 
workflows, including denial management. It is unclear what the impact 
of a hospital or practice adopting FHIR-enabled certified EHR 
technology might have on the denial management needs since the aim of 
the Prior Authorization API is to improve prior authorization 
transparency and communication, ultimately reducing denials. 
Furthermore, it is unclear how many of the roughly 162 clearinghouse 
firms currently utilize FHIR standards as a part of their business 
operations or to what extent APIs are integrated into their workflows. 
Without a baseline understanding of API utilization among this 
population of HIPAA covered entities, it is challenging to predict 
their future adoption of FHIR standards and the economic impact on 
their sector of the health care industry. HHS solicits commenter 
feedback on the extent to which clearinghouses have experience 
developing and implementing FHIR APIs or whether their systems can 
engage with another party's FHIR API within their workflow. HHS 
solicits comment on the level of effort it would require for a health 
care clearinghouse to update their processing systems to accommodate 
these proposals. HHS invites comments on these uncertainties.

which were adopted by the Secretary in the HTI-4 final rule (90 FR

part of the FY 2026 IPPS/LTCH final rule (90 FR 36536). Since the FY 
2026 IPPS/LTCH final rule appeared in the Federal Register, newer 
versions of the standards adopted by the Secretary in the HTI-4 final 
rule have been released. Therefore, ONC proposes to adopt the following 
standards on behalf of the Secretary:

    As part of the HTI-4 final rule, ONC finalized certification 
criteria for electronic prior authorization in the ONC Health IT 
Certification Program that incorporated the CRD, DTR, and PAS IGs. As 
part of this proposed rulemaking, CMS is proposing to incorporate 
cross-references to 45 CFR 170.215 where these standards would be 
adopted as part of proposed technical requirements for payer APIs CMS 
previously established in the 2020 CMS Interoperability and Patient 
Access and the 2024 CMS Interoperability and Prior Authorization final 
rules.
    ONC analysis of these new standard versions finds that the changes 
between currently adopted standard versions and these new standard 
versions are small in scope and would not require significant effort to 
adopt. Furthermore, ONC adopted the current standard versions in 
regulation as part of the HTI-4 final rule, with no required date to 
adopt the new certification criteria and the associated standards, 
lowering any duplication of effort to first adopt the current standard 
version and the proposed new standard version (90 FR 36536 through 
37308). ONC also finds--aligning with the impact analysis for this 
proposed CMS rulemaking--that the proposed updates would not require 
new adoption of technology by health IT users or adoption of new 
certification criteria by developers of certified health

[[Page 20029]]

IT, as those requirements are associated with finalized rulemaking. ONC 
estimates that developers of certified health IT would face little 
burden to adopt the updated standard version given these factors. ONC 
estimates that the effort on developers of certified health IT to adopt 
these standard versions would be de minimis. This analysis parallels 
the ONC HTI-2 proposed rule impact analysis for the proposed update to 
adopt SMART App Launch IG version 2.2 (89 FR 63498).\443\ Similarly 
here, the proposed update from SMART App Launch IG version 2.0 to 2.2 
involved enhancements that would require low effort on developers of 
certified health IT to adopt for already adopted certification criteria 
and associated standards. Public comments from the HTI-2 proposed rule 
did not raise any concerns with our impact analysis of the SMART App 
Launch IG version update, but we recognize that differing standard 
maturity levels and implementation challenges for the previously 
proposed IG updates may create more burden on developers to update 
their certified technology. We request comment to that effect on the 
expected level of burden to update certified technology to the latest 
IG versions proposed previously.

b. Rulemaking Costs to Impacted Payers Related to CMS Proposals
(1) Methodology of Attributing Cost Among Impacted Payers
    To analyze the cost of the proposals related to prior authorization 
of drugs, we allocate costs by the three federally funded programs that 
would be impacted by this provision--MA; Medicaid and CHIP (including 
state Medicaid and CHIP FFS programs, Medicaid managed care plans, and 
CHIP managed care entities); and QHPs on the FFEs. As the cost is 
shared by the 341 parent organizations offering impacted health plans, 
including state Medicaid and CHIP agencies, there is no readily 
available way to allocate costs per parent organization across programs 
as the percentage of each parent organization's expenditure on the 
different programs is not publicly available.
    To address this, we use the CMS Medical Loss Ratio (MLR), 
acknowledging its data limitations as we did in the 2020 CMS 
Interoperability and Patient Access and 2024 CMS Interoperability and 
Prior Authorization final rules (85 FR 25612 through 25616 and 89 FR 
8969). Our actuaries use the public CMS MLR files, which break out 
total premiums among the various programs.\444\ Table 24 presents the 
2022 MLR data of premiums by program and the resulting percentages by 
program. We use these percentages to allocate costs by program in Table 
25, which forms a basis for calculating the federal government's cost 
for the proposals in this proposed rule described in Table 32.

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

    While most of the CMS proposals in this proposed rule apply to all 
impacted payers, there are two proposals that do not. For these 
proposals, Table 24 shows premium allocation by program.\445\ For 
example, $246 billion of the $549 billion total premium is spent on MA 
plans ($246 / $549 = 44.81%).
---------------------------------------------------------------------------

    \445\ Medicaid and CHIP patients may pay premiums under certain 
circumstances.
---------------------------------------------------------------------------

    First, as shown in Tables 14 and 20 in sections IV.C. and IV.E. of 
this proposed rule, the prior authorization decision timeframes for 
drugs proposal only applies to the 66 parent organizations offering 
QHPs on the FFEs. For this proposal, 100 percent of the cost is 
allocated to QHPs on the FFEs. Second, as shown in Table 24, the 
proposed NCPDP SCRIPT standard for prior authorization of drugs covered 
under a pharmacy benefit only applies to two programs, those being: (1) 
Medicaid and CHIP; and (2) QHPs on the FFEs. For this provision, we 
allocated 68.91 percent of the total cost to Medicaid and CHIP ($209 / 
$303 = 68.91%) and 31.09 percent of the total cost to QHP on the FFEs 
($94 / $303 = 31.09%). Note, $303 billion is the aggregate amount of 
premium costs associated with these two programs: (1) Medicaid and CHIP 
at $209 billion; and (2) QHPs on the FFEs at $94 billion. Therefore, 
68.91 percent equals the estimated $209 billion in premiums that would 
be spent by Medicaid and CHIP and 31.09 percent equals the $94 billion 
in premiums that would be spent by QHPs on the FFEs.

    Table 25 reflects the total cost to impacted payers resulting from 
CMS proposals in this section. This cost is attributed among: MA 
organizations; Medicaid and CHIP (including state Medicaid and CHIP FFS 
programs, Medicaid managed care plans, and CHIP managed care entities); 
and QHP issuers on the FFEs using the methodology discussed in section 
V.C.2.b.(1). of this proposed rule. In total, the three programs would 
incur an estimated $141.26 million over 10 years to implement these CMS 
proposals described in sections V.C.2.b.(1).(a). through 
V.C.2.b.(1).(g). of this proposed rule.

(a) Costs Associated With the Proposal To Incorporate Into the Prior 
Authorization API Coverage and Documentation Requirements To Support 
Electronic Prior Authorization for Drugs Covered Under a Medical 
Benefit for All Impacted Payers (42 CFR 422.122, 42 CFR 431.80, 42 CFR 
438.242, 42 CFR 457.732, 42 CFR 457.1233, and 45 CFR 156.223)
    In this proposed rule, we would expand upon the Prior Authorization 
API provisions finalized in the 2024 CMS Interoperability and Prior 
Authorization final rule (89 FR 8897) by requiring impacted payers to 
incorporate prior authorization coverage and documentation requirements 
for drugs covered under a medical benefit into the Prior Authorization 
API beginning in 2027. If finalized as proposed, CMS anticipates that 
there would be a 2027 compliance date for this proposal. This should 
allow for approximately 1 year of lead time between publication and the 
compliance date.
    To incorporate drug coverage and documentation requirements into 
the existing Prior Authorization API, we estimate that all impacted 
payers would need to conduct similar work phases as for implementation 
of the API such as design, development testing, and long-term support 
and maintenance. For prior authorization of drugs, some, but not all, 
tasks would be necessary for the initial development work, such as 
identifying the relevant drugs, system connections to formularies or 
PBMs, and programming the Prior Authorization API to include drugs 
covered under a medical benefit. Some of the same expertise would be 
required to develop and implement prior authorization policies and 
systems processes for drugs covered under a medical benefit as were 
needed to develop a Prior Authorization API for non-drug items and 
services. Still, it would not require the same level of effort as for 
the development of the API itself.
    Acknowledging that impacted payers would have the technical 
infrastructure in place, the deployment of these proposals is estimated 
at 127,670 burden hours to calculate the estimated cost, which results 
in $15,348,797 for all 341 impacted payers (see costs determination in 
Table 26). We distributed the cost over approximately 1 calendar year 
to ensure impacted payers can identify, analyze, and program their 
systems to include drugs covered under a medical benefit. Since this 
rule proposes a compliance date of October 1, 2027 for this proposal, 
CMS acknowledges that the development timeframe would likely overlap 
with impacted payers' development efforts related to the API 
requirements finalized in the 2024 CMS Interoperability and Prior 
Authorization final rule. Due to this overlap in development activity, 
we anticipate that the one-time costs incurred in 2026 would double due 
to the increase in developer labor hours needed to progress both 
technological builds simultaneously. To provide an approximate 
adjustment accounting for this burden, we double the amount of cost 
estimated to fall in the year 2026 (approximately 25 percent of the 
total development burden) which results in an additional $3,837,199 
across all 341 impacted payers ($15,348,797.38 x 0.25 = $3,837,199.35) 
which is reflected in the annual cost associated with each proposal in 
Table 33. The resulting total is $19,185,997 in one-time implementation 
cost across all impacted payers. We request comment on these estimates.

(b) Costs Associated With the Proposed Addition of Prior Authorization 
Information About Drugs to the Access APIs for Impacted Payers (42 CFR 
422.119, 42 CFR 422.121, 42 CFR 431.60, 42 CFR 431.61, 42 CFR 438.242, 
42 CFR 457.730, 42 CFR 457.731, 42 CFR 457.1233, 45 CFR 156.221, and 45 
CFR 156.222)
    We are proposing that the same policies that require impacted 
payers to make available--via the Access APIs--information about prior 
authorization requests and decisions for non-drug items and services 
for which an impacted payer has data in the patient's record would now 
apply to drugs as well, as described in section II.F.1. of this 
proposed rule. If finalized as proposed, CMS anticipates that there 
will be a 2027 compliance date for this proposal. This should allow for 
approximately 1 year of lead time between publication and the 
compliance date.
    As in the 2020 CMS Interoperability and Patient Access and 2024 CMS 
Interoperability and Prior Authorization final rules, we assume that 
for the technical work, impacted payers would conduct three work 
phases: (1) design; (2) development and testing; and (3) support and 
maintenance (85 FR 25605 and 25623 and 89 FR 8948, 8950, and 8953). In 
this proposed rule, we assume the same phases of work would take place 
for the tasks related to the new proposals related to the APIs, with a 
different level of effort during each work phase. In the initial design 
phase, tasks include determining available resources (for instance, 
personnel, hardware, cloud storage space, etc.); assessing whether to 
use in-house or contracted resources to conduct the programming; and 
convening a team to scope, build, test, and maintain work.
    Adding prior authorization information to the existing Access APIs 
upon request should not require substantive technological changes but 
could require programming and impact data storage. Additional 
programing and data storage reflects only a small part of the total 
cost of API implementation and, while cost may vary depending on health 
plan, we chose to use 15 percent of full API implementation cost to 
reasonably approximate the burden associated with these activities. We 
estimate the effect to be 15 percent of the prior cost for the Access 
APIs' implementation as a baseline and invite stakeholders to comment 
on this 15 percent estimate. We estimate that a parent organization 
adding this prior authorization information to the Access APIs would 
require on average 278 hours, with the corresponding cost obtained by 
multiplying the estimated hours by the median wage per hour. Since this 
rule proposes a compliance date of October 1, 2027 for this proposal, 
CMS acknowledges that the development timeframe would likely overlap 
with impacted payers' development efforts related to the API 
requirements finalized in the 2024 CMS Interoperability and Prior 
Authorization final rule. Due to this overlap in development activity, 
we anticipate that the one-time costs incurred in 2026 would double due 
to the increase in developer labor hours needed to progress both 
technological builds simultaneously. To provide an approximate 
adjustment accounting for this burden, we double the amount of cost 
estimated to fall in the year 2026 (approximately 25 percent of the 
total development burden) which results in an additional $2,775,755 
across all 341 impacted payers ($11,021,098.18 x 0.25 = $ 2,755,274.55) 
which is reflected in the annual cost associated with each proposal in 
Table 33. The resulting total is $13,776,373 in one-time implementation 
cost across all impacted payers. We request comment on these estimates.

(c) Costs Associated With the Proposal To Support the NCPDP SCRIPT 
Standard for the Electronic Prior Authorization of Drugs Covered Under 
a Pharmacy Benefit for State Medicaid and CHIP Fee-for-Service 
Programs, Medicaid Managed Care Plans, CHIP Managed Care Entities, and 
QHP Issuers on the Federally-facilitated Exchanges (42 CFR 431.80, 42 
CFR 438.242, 42 CFR 457.732, 42 CFR 457.1233, and 45 CFR 156.223)
    We are proposing to require state Medicaid and CHIP FFS programs, 
Medicaid managed care plans, CHIP managed care entities, and QHP 
issuers on the FFEs to support a version of the NCPDP SCRIPT standard 
adopted by the Secretary in 45 CFR 170.205(b) when performing 
electronic prior authorization for drugs covered under a pharmacy 
benefit. If finalized as proposed, CMS anticipates that there will be a 
2027 compliance date for this proposal. This should allow for 
approximately 1 year of lead time between publication and the 
compliance date.
    This proposed rule does not intend to address the prior 
authorization criteria these impacted payers use to make decisions 
about coverage. However, supporting the proposed NCPDP SCRIPT standard 
should make the prior authorization process less burdensome for payers 
and providers and could improve timeliness to approved prescriptions 
for patients. Specifically, based on stakeholder feedback, we believe 
providers already using electronic prescribing software have access to 
the NCPDP SCRIPT standard for electronic prior authorization.
    We reviewed the 2024 Part D and Health IT Standards final rule (89 
FR 51238) and the 2020 Medicare Part D ePA final rule (85 FR 86824) to 
obtain cost estimates for this proposal. In these rules, CMS indicates 
that the technical tasks (for instance, building the infrastructure and 
logic) to support the proposed NCPDP SCRIPT standard can vary based on 
how the impacted payer documents the prior authorization criteria. The 
average cost per impacted payer is estimated at $6,500, regardless of 
the size and expertise of the payer. In the 2020 Medicare Part D ePA 
final rule, the $6,500 figure included the payer's internal costs, 
including labor, initial development and programming, and systems 
support to transform each of its CMS-approved prior authorization 
criteria from a manual process suitable for telephonic or manual 
efforts. Since the publication of the 2020 Medicare Part D ePA final 
rule, CMS has not collected new data related to the cost of supporting 
the NCPDP SCRIPT standard among impacted payers. In the absence of 
updated data, we have adjusted the estimated $6,500 for inflation using 
the BLS Consumer Price Index Inflation Calculator to obtain a more 
reasonable estimate of the potential cost. The resulting cost is 
approximately $12,500 in inflation-adjusted dollars. Similar to the 
other proposals implicating systems build for the prior authorization 
of drugs, this rule proposes a compliance date of October 1, 2027 for 
the adoption of the NCPDP SCRIPT standard. CMS acknowledges that the 
development timeframe would likely overlap with impacted payers' 
development efforts related to the API requirements finalized in the 
2024 CMS Interoperability and Prior Authorization final rule. Due to 
this overlap in development activity, we anticipate that the one-time 
costs incurred in 2026 would double due to the increase in developer 
labor hours needed to progress both technological builds 
simultaneously. To provide an approximate adjustment accounting for 
this burden, we double the amount of cost estimated to fall in the year 
2026 (approximately 25 percent of the total development burden) which 
results in an additional $743,750 across all 341 impacted payers 
($2,975,000 x 0.25 =$ 743,750) which is reflected in the annual cost 
associated with each proposal in Table 33. The resulting total is 
$3,718,750 in one-time implementation cost across all impacted payers. 
We request public comment on these estimates. We solicit comments from 
impacted payers on this approach and other sources of data we could use 
to determine this cost estimate.

(d) Costs Associated With the Proposal To Support the NCPDP Formulary & 
Benefits Standard and the NCPDP Real-Time Prescription Benefit Standard 
Adopted for the Electronic Prior Authorization of Drugs Covered Under a 
Pharmacy Benefit for State Medicaid and CHIP Fee-for-Service Programs, 
Medicaid Managed Care Plans, CHIP Managed Care Entities, and QHP 
Issuers on the Federally-Facilitated Exchanges (42 CFR 431.80, 42 CFR 
438.242, 42 CFR 457.732, 42 CFR 457.1233, and 45 CFR 156.223)
    We are proposing to require state Medicaid and CHIP FFS programs, 
Medicaid managed care plans, CHIP managed care entities, and QHP 
issuers on the FFEs to support the NCPDP F&B standard version 60 
adopted by the Secretary in 45 CFR 170.205(u), for transmitting 
formulary and benefit information between providers and impacted 
payers, and NCPDP RTPB standard version 13 adopted by the Secretary in 
45 CFR 170.205(c), to enable real-time, patient-specific prescription 
benefit information to be delivered to providers at the point of 
prescribing. If finalized as proposed, CMS anticipates that there will 
be a 2027 compliance date for this proposal. This should allow for 
approximately a year of lead time between publication and the 
compliance date. Consistent with the initial adoption of these 
standards in the 2020 Medicare Part D ePA final rule, we are advancing 
these proposals with unclear costs for these impacted payers, but a 
clear vision that it is important to invest in these programs due to 
the increasing costs of drugs and potential savings that could be 
realized through the proposed NCPDP F&B and NCPDP RTPB standards. Cost 
associated with the adoption of these standards remain unclear due to a 
lack of robust public data on the implementation of the proposed NCPDP 
F&B and NCPDP RTPB standards among Medicare PDPs. An understanding of 
the adoption rate in Medicare Part D and the cost of implementation 
among those plans could support the development of a cost analysis in 
this proposed rule. CMS solicits comment on the cost of the proposed 
NCPDP F&B and NCPDP RTPB standards among impacted payers who have 
already implemented them in their Medicare Part D lines of business and 
specifically requests comment on the type of implementation activities 
associated with cost, such as software development and testing. 
Further, CMS solicits comments from impacted payers who would be 
adopting these standards for the first time with respect to their 
anticipated implementation activities and anticipated costs for 
expenses such as software licensing, system integration, API 
development, and testing. CMS requests comment comparing the cost of 
implementing these standards for the first time with the estimated one-
time cost of implementing the NCPDP SCRIPT standard of $12,500 per 
entity, plus the additional markup for the cost of labor in the year 
2026.
(e) Costs Associated With the API Proposals for the Small Group Market 
Qualified Health Plan Issuers on the Federally-facilitated Small 
Business Health Options Program Exchanges (45 CFR 156.221, 45 CFR 
156.222, and 45 CFR 156.223)
    In this proposed rule we are proposing to apply existing 
requirements to small group market QHP issuers on the FF-SHOPs as 
described in section II.D. of this proposed rule. Consistent with the 
provisions of the 2020 CMS Interoperability and Patient Access final 
rule (85 FR 25522), we are proposing the development and implementation 
of a standards-based Patient Access API that permits third-party apps 
to retrieve standardized data for adjudicated claims, encounters with 
capitated providers, provider remittances, enrollee cost sharing, 
reports of lab test results, and preferred drug lists at the request of 
the patient. We are proposing to apply this requirement to small group 
market QHP issuers on the FF-SHOPs for plan years beginning on or after 
January 1, 2028.
    We are also proposing that small group market QHP issuers on the 
FF-SHOPs implement and maintain standards-based Provider Access, Payer-
to-Payer, and Prior Authorization APIs, consistent with requirements in 
the 2024 CMS Interoperability and Prior Authorization final rule (89 FR 
8817, 8855, and 8897). We are proposing compliance dates for the 
Provider Access and Payer-to-Payer API requirements of plan years 
beginning on or after January 1, 2028, and an October 1, 2027 
compliance date for the Prior Authorization API requirements. In that 
final rule, we finalized another set of requirements for impacted 
payers (excluding small group market QHP issuers on the FF-SHOPs) to 
report on the Patient Access API and publicly report prior 
authorization metrics (89 FR 8784 and 8897). We do not anticipate that 
there would be added burden for the parent organizations that offer 
individual market QHPs on the FFEs to implement these proposals for 
their small group market QHPs on the FF-SHOPs, because the parent 
organizations are already required to implement these same policies for 
their individual market QHPs on the FFEs.
(f) Costs Associated With the Proposal To Report Usage Metrics for 
Provider Access, Payer-to-Payer, and Prior Authorization APIs (42 CFR 
422.121, 42 CFR 422.122, 42 CFR 431.61, 42 CFR 431.80, 42 CFR 438.242, 
42 CFR 457.731, 42 CFR 457.732, 42 CFR 457.1233, 45 CFR 156.222, and 45 
CFR 156.223)
    CMS proposes to require impacted payers to report metrics about the 
usage of the Provider Access, Payer-to-Payer, and Prior Authorization 
APIs in the form of aggregated, de-identified data. We estimate that 
this proposal will require 100 hours of labor by a Software

[[Page 20034]]

and Web Developer at $124.34 ($12,434 annually) per impacted payer for 
the first year, with no maintenance burden. We also estimate 60 hours 
of labor by a Business Operations Specialist at $78.14 ($4,688 
annually) per impacted payer for the first year and 40 hours for 
maintenance burden ($3,126 annual cost). The aggregate burden for 341 
parent organizations would be 55,000 hours and 14,000 hours (rounded) 
for the first and subsequent years at a cost of $5.8 million and $1.1 
million. For additional information on this burden estimate, see 
section IV.C.2. of this proposed rule.
(g) Costs Associated With the Proposal To Report Payer API Endpoints 
and Associated Information for CMS To Publish (42 CFR 422.119, 42 CFR 
422.120, 42 CFR 422.121, 42 CFR 422.122, 42 CFR 431.60, 42 CFR 431.61, 
42 CFR 431.70, 42 CFR 431.80, 42 CFR 438.242, 42 CFR 457.730, 42 CFR 
457.731, 42 CFR 457.732, 42 CFR 457.760, 42 CFR 457.1233, 45 CFR 
156.221, 45 CFR 156.222, and 45 CFR 156.223)
    CMS proposes to require impacted payers to report all API endpoints 
in the form of an Endpoint Resource, a direct URL for their API's FHIR 
capability statements, and required documentation such as authorization 
and authentication protocols, implementation details, and API 
registration information to CMS within 1 week of any changes and to 
verify this every 12 months. We estimate that this proposal would 
require 2 hours of labor by a Business Operations Specialist at $78.14 
($156.28 annually) per impacted payer and for all impacted payers we 
estimate that the reporting burden would be $53,291 annually. For 
additional information on this burden estimate, see section IV.C.3. of 
this proposed rule.
3. Transfers
a. Rulemaking Costs Related To the Proposal To Define ``Failure To 
Report'' in Open Payment Non-Compliance (42 CFR 403.902)
    We propose in section II.G. of this proposed rule to create a new 
definition of ``failure to report'' that includes the failure to 
provide requested documentation during an audit. CMS has both CMP 
authority in 42 CFR 403.912(a) and audit authority in 42 CFR 
403.912(e)(2). CMS began implementing the Open Payments audit program 
in 2022 and conducted the first full audit during the 2023 cycle. Over 
this 2-year period CMS audited 16 total entities. Due to the relatively 
short implementation period of the Open Payments audit program, we have 
limited historical data to use in estimating the amount of CMPs that 
would be imposed as a result of the proposed ``failure to report'' 
definition as it relates to audit findings. In the absence of robust 
audit data, we are relying on information from the 2022 to 2023 audits 
and the statutorily mandated knowing ``failure to report'' CMP 
methodology (section 1128G(b)(2) of the Act) to calculate the estimated 
cost associated with this proposal.
    Based on previous audit sample sizes, CMS estimates an average of 
10 reporting entities will be audited (out of approximately 1,700 
reporting entities) annually. During the 2022 to 2023 audit cycles, 
approximately 25 percent of sampled entities failed to fully or 
partially comply with audit requests. CMS anticipates that the proposed 
definition of ``failure to report'' would compel entities to fully 
comply with audit requests. Without implementation experience to draw 
from, CMS can only estimate how the change in definition would impact 
compliance with audit requirements. CMS assumes that the non-compliance 
rate would drop to approximately 10 percent of sampled entities if the 
definition is finalized. CMS invites comment on this assumption. Based 
on an expected sample size of 10 entities, CMS anticipates imposing 
CMPs for one reporting entity per year (10 x 10 percent). As knowing 
``failure to report'' CMP amounts are determined by the Act on a per-
record basis between $10,000 and $100,000 for each failure, with a 
program year ceiling of $1,000,000 (adjusted annually in 45 CFR part 
102), the amount of CMPs imposed on a single entity could vary 
depending on how many instances of non-compliance CMS identifies and 
the duration of the non-compliance. CMS uses the median per-record 
knowing ``failure to report'' CMP amount of $77,371 (considering a 
range of $14,067 and $140,674 for 2024, per 45 CFR part 102) to 
calculate the total amount of anticipated CMPs for a non-compliant 
entity. Based on the results of previous audits, we assume a non-
compliant entity would fail to report a total of five records per 
program year, but we invite comment on this assumption.
    Therefore, CMS estimates that on average one entity per audit cycle 
would be found non-compliant in the reporting of approximately five 
records per program year, at an average rate of $77,371 per record, or 
$386,855 ($77,371 x 5). Open Payments program audits evaluate a 3-year 
lookback period, which would result in a total of $1,160,565 ($386,855 
x 3 years) in estimated CMPs during the annual audit cycle. This 
information can be seen in Table 29. CMS invites comments on these 
assumptions and calculations.

b. Costs to the Government
    CMS estimates that the federal government would incur transfer 
costs from the three federally funded programs that would be impacted 
by the proposed requirements to expand the prior authorization 
provisions finalized in the 2024 CMS Interoperability and Prior 
Authorization final rule to include drugs and the proposed requirements 
associated with reporting API metrics, those being MA; Medicaid and 
CHIP (including state Medicaid and CHIP FFS programs, Medicaid managed 
care plans, and CHIP managed care entities); and QHPs on the FFEs. We 
use the CMS internal data from the CMS Trustees' Report and the 
``Fiscal Year 2025 Budget in Brief'' to calculate federal costs for MA 
organizations.446 447 Our

[[Page 20035]]

calculations, shown in Table 30, indicate that the Trust Fund would pay 
about 34 percent of impacted payers' costs over the next 10 years. The 
remaining costs, for the approximately 99 percent of plans bidding 
below the benchmark, are borne by the impacted payers.

    For Table 32, the 10-year total cost to the government assumptions 
include the following:
     The three columns in Table 32 list the cost incurred by 
the federal government as a result of the proposals in this rule. We 
applied the proportions of Tables 31 and 30 for MA and Medicaid. For 
the cost associated with QHPs on the FFEs, although the federal 
government does not subsidize QHPs on the FFEs it does provide PTC 
subsidies to eligible enrollees. We provide a PTC cost estimate that 
reflects a global premium increase across all QHPs on the FFEs of the 
projected expense burden.
     PTC Payments: The government offers QHP eligible enrollees 
PTCs to help cover the enrollees' plan premiums. The PTCs are only 
available

[[Page 20036]]

to enrollees of individual market QHPs purchased through an SBE, SBE-
FP, or FFE. Enrollees of small group market QHPs purchased through the 
FF-SHOP are not eligible for PTCs. There would be federal PTC impacts 
to the extent that issuers increase premiums for individual market QHPs 
on the FFEs.
    The PTC estimate reflects a global premium increase across all QHPs 
on the FFEs of the projected expense burden. The methodology to 
estimate the PTC impact of the projected expense burden is consistent 
with that used to estimate the PTC impact in the 2020 CMS 
Interoperability and Patient Access and the 2024 CMS Interoperability 
and Prior Authorization final rules (85 FR 25612 and 89 FR 8972). 
Within the FFE states, the estimated expense burden would impact 
premium rates in the individual and small group markets. PTCs are only 
available for the individual plans sold on the Marketplace and are 
calculated as a function of the second lowest-cost silver plan and the 
eligible individual's household income. The estimate of these impacts 
uses the global assumption that the industry would increase the second 
lowest-cost silver plan premium rate in the same amount as the overall 
projected premium rate increase as a result of the RIA cost estimate. 
The overall rate increase, determined by internal estimates produced by 
the CMS Office of the Actuary (OACT), is applied to the projected PTC 
payments in the FFE states to estimate the proposed rule's impact on 
PTC payments.
    Table 33 provides the total cost of the rule over 10 years, broken 
out by proposal. This table only reflects proposed policies determined 
to have a non-negligible cost impact. Tables 21 through 30 form a basis 
for Table 33, the Total Cost of Proposed Policies by Year, which 
presents the costs of this proposed rule by year, in the aggregate, by 
program, and with allocations to plans and the government. The total 
10-year cost in Table 33 (excluding PTC payments and savings from prior 
authorization) is $396.91 million.

BILLING CODE 4150-28-C
4. Regulatory Review Cost Estimation
    Due to the uncertainty involved with accurately quantifying the 
number of entities that will review the rule, we assume that the total 
number of unique commenters on the 2022 CMS Interoperability and Prior 
Authorization proposed rule will be the number of reviewers of this 
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 2022 CMS Interoperability and Prior 
Authorization 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 past commenters (900) would be a 
fair estimate of the number of reviewers of this rule. We welcome any 
comments on the approach in estimating the number of entities which 
will review this proposed rule. We also recognize that different types 
of entities are in many cases affected by mutually exclusive sections 
of this proposed rule; therefore, for the purposes of our estimate we 
assume that each reviewer reads approximately 50 percent of the rule. 
We seek comments on this assumption.
    Using the wage information from the BLS for medical and health 
service managers (Code 11-9111), we estimate that the cost of reviewing 
this rule is $113.42 per hour, including overhead and fringe 
benefits.\448\ In the 2024 CMS Interoperability and Prior Authorization 
proposed rule, we estimated that it would take a manager-level reviewer 
10 hours to read the entire rule (87 FR 76343). Based on our prior 
assumption assigning each reviewer 50 percent of the rule content and 
feedback from industry stakeholders, we estimate that it would take 10 
hours total for staff to review. We estimate this amount of time 
because, while the majority of the prior authorization and API-related 
proposals build on the familiar framework of policies finalized in the 
2024 CMS Interoperability and Prior Authorization final rule, we 
acknowledge that the addition of drugs to these policies and the 
systems associated with the prior authorization of drugs under a 
medical and pharmacy benefit add new complexity to concepts which may 
already be familiar to reviewers. Further, the proposal to adopt the 
FHIR standard and applicable IGs as the transaction standard for HIPAA 
Administrative Simplification ``referral certification and 
authorization'' and ``eligibility for a health plan'' transactions 
related to prior authorization may require reviewers to conduct 
additional research cross-referencing existing HIPAA regulations to 
achieve understanding. Therefore, we estimate that the amount of time 
needed to review the rule would not decrease. For each entity that 
reviews the rule, the estimated cost is $1,134.20 (10 hours x $113.42) 
and we estimate that the total cost of reviewing this regulation is 
$1,020,780 ($1,134.20 x 900). In addition, we anticipate that certain 
reviewers will incur familiarizations costs that reflect the time and 
effort taken to seek answers to policy questions and to synthesize and 
disseminate the information on the proposed requirements to the 
relevant decision-makers within their organization. We estimate that 
approximately one quarter of all anticipated reviewers, or 225 (900/4 = 
225), will engage in familiarization activities based on the proportion 
of comments submitted by professional associations of impacted payers, 
providers, and patient advocacy organizations on our previous rules. We 
expect it would take these medical and health service managers (Code 
11-9111) approximately 20 hours at a rate of $113.42 to familiarize 
themselves with the provisions in this proposed rulemaking. This would 
result in a burden of $2,268 (20 hours x $113.42 = $2,268.40) for a 
single reviewer and $510,390 for all 225 reviewers to familiarize 
themselves and their organizations with the content of this proposed 
rule. In total, we estimate the one-time cost of review and 
familiarization activities would be $1,531,170 ($1,020,780 + $510,390 = 
$1,531,170). We seek comment on these assumptions.

D. Alternatives Considered

    After considering the alternatives to the proposals in this rule, 
we concluded that the proposed policies in this rulemaking represent 
the best options to mitigate ongoing burdens identified in public 
comments about prior authorization of drugs. Those public comments and 
engagements with industry experts over the past 2 years support our 
conclusions that none of the alternatives would address remaining 
critical issues related to patient, provider, or payer burden and 
interoperability. A key alternative across all policies in this 
proposed rule is the proposed compliance timeline. We considered 
proposing earlier compliance deadlines in 2027, which would accelerate 
the important outcomes we aim to achieve by improving the transfer of 
electronic health data for patients, providers, and plans. For example, 
we considered providing less time, such as 6 months, for impacted 
payers to implement the proposed technical standards. However, CMS 
believes that an implementation timeline of less than one year would be 
more likely to result in inoperative or deficient technical builds. If 
developers have inadequate development and testing time, we risk 
dysfunctional systems that do not achieve the policy goals stated in 
this proposed rule. Based on anecdotal industry feedback, we estimate 
that the additional labor needed to accelerate technical development 
timelines to less than a year could double the costs estimated in this 
rule. For example, the one-time implementation cost of incorporating 
information on drugs into the Prior Authorization API would increase 
for a single entity to approximately $90,000 (45,000 x 2 = 
$90,000).\449\ CMS seeks to support industry partners in their efforts 
to achieve interoperability and has determined that an accelerated 
timeline would significantly increase the cost to impacted payers, 
while jeopardizing the effectiveness of the proposed standards, and 
that the proposed compliance deadlines are most appropriate.
---------------------------------------------------------------------------

    \449\ Cost associated with the proposal to incorporate into the 
Prior Authorization API coverage and documentation requirements to 
support electronic prior authorization for drugs covered under a 
medical benefit are estimated to be approximately $45,011.14 per 
impacted payer for a one-time implementation cost.
---------------------------------------------------------------------------

1. Alternatives Considered for the Proposal To Incorporate Drugs 
Covered Under a Medical Benefit Into the Prior Authorization API for 
Impacted Payers
    We considered encouraging impacted payers to voluntarily update 
their prior authorization processes for drugs under a medical benefit, 
rather than proposing it as a requirement. A voluntary approach could 
allow plans the flexibility to tailor their incorporation of drugs 
covered under a medical benefit to their specific systems. Encouraging 
voluntary incorporation might create space for industry leaders to 
coalesce around best practices and develop consensus. We also 
considered proposing to expand the Prior Authorization API provisions 
to drugs covered under a medical benefit at a later date to allow 
impacted payers additional time to comply with the requirements 
finalized in the 2024 CMS Interoperability and Prior Authorization 
final rule. However, this would cause a delay in addressing a well-
known

[[Page 20039]]

industry issue. In considering these alternatives, we assume that some 
industry leaders would likely volunteer to adopt this policy based on 
their voluntary participation in other HHS initiatives like the prior 
authorization pledge.\450\ The roughly 60 health plan firms \451\ would 
incur a one-time implementation cost of approximately $45,000 to 
incorporate drugs into their existing Prior Authorization APIs and 
approximately $11,200 in maintenance cost annually thereafter per the 
estimates in this proposed rule. The remaining non-volunteer health 
plans would incur no burden associated with this policy in the short 
term by deferring implementation. Based on stakeholder feedback, CMS is 
confident that industry is heading in the direction of prior 
authorization of drugs via API and that eventually these costs to 
integrate drugs would be incurred regardless. At the same time, the 
administrative cost to providers from inefficient manual drug prior 
authorization processes would persist as some plans delayed 
incorporating drugs into their Prior Authorization APIs. Based on these 
factors, we concluded that a voluntary and potentially inconsistent 
application of this policy does not adequately further CMS's health 
care and public health objectives. Therefore, we are proceeding with 
our proposal to expand the Prior Authorization API provisions to 
include drugs covered under a medical benefit and solicit public 
feedback.

2. Alternatives Considered for the Proposal To Support the Proposed 
NCPDP Standards for State Medicaid and CHIP Fee-for-Service Programs, 
Medicaid Managed Care Plans, CHIP Managed Care Entities, and Qualified 
Health Plan Issuers on the Federally-Facilitated Exchanges
    We considered an alternative standard to the NCPDP SCRIPT standard, 
such as the NCPDP Telecommunication Standard, Version D, Release 0 
(Version D.0), used by pharmacies as mandated under HIPAA. The cost to 
implement the Telecommunications Standard, which is already mandated 
for use under HIPAA and has been widely adopted, would likely be 
negligible, since impacted payers already use this standard in pharmacy 
claims billing. However, this standard does not support data exchange 
between payers and providers, nor does it support access to formulary 
or medication history. Despite this alternative's low-cost burden, this 
standard would not achieve the desired electronic data exchange and CMS 
concluded that it would not be effective for the prior authorization of 
drugs. Additionally, this standard cannot be used with the widely used 
NCPDP SCRIPT standard. We also considered the X12N 278 Health Care 
Services Review--Request for Review and Response transaction standard. 
This standard is currently used by providers to submit prior 
authorization, referral, and certification requests to payers. The cost 
of requiring this X12N 278 standard would likely be minimal considering 
it is already an established HIPAA standard and would be considered an 
usual and customary business expense. However, this standard is not 
intended or designed to be used for drugs covered under a pharmacy 
benefit. Furthermore, these standards were evaluated by the Medicare 
Part D program and NCPDP, and they determined that the NCPDP SCRIPT 
standard better supports electronic prior authorization of drugs 
covered under a pharmacy benefit than the alternatives (85 FR 86827 
through 86830). When considering the functionalities of these standards 
and Medicare Part D and NCPDP's evaluations, we determined that the 
NCPDP Telecommunication and X12N 278 transaction standards do not 
support the intent of this proposal. This led us to conclude that the 
NCPDP SCRIPT standard's technical advantages, combined with the 
supporting NCPDP F&B and NCPDP RTPB standards, could maximize benefits 
to patients, providers, and payers, and align with other regulatory 
requirements. These factors made these three proposed NCPDP standards 
the most appropriate option for this proposed rule and justify the 
estimated cost of implementation. Therefore, we are proposing to 
require state Medicaid and CHIP FFS programs, Medicaid managed care 
plans, CHIP managed care entities, and QHP issuers on the FFEs to 
support the proposed NCPDP standards for electronic prior authorization 
of drugs covered under a pharmacy benefit.
3. Alternatives Considered for the Proposals for Prior Authorization 
Decision Timeframes for State Medicaid and CHIP Fee-for-Service 
Programs, Medicaid Managed Care Plans, CHIP Managed Care Entities and 
Qualified Health Plan Issuers on the Federally-Facilitated Exchanges
    For the prior authorization decision timeframes for non-drug items 
and services, we considered retaining the current prior authorization 
decision timeframe of 15 days for standard requests for QHP issuers on 
the FFEs. However, we believe that aligning the standard prior 
authorization request decision timeframe across all impacted payers is 
essential in achieving the agency's goal of patient-centered care and 
ensuring continuity of care for patients transitioning between payers. 
While we do not estimate a cost associated with the time to respond to 
prior authorization requests since they are considered usual and 
customary business practices, CMS believes that the alignment of these 
timeframes could ultimately result in operational efficiencies across a 
health plan's multiple lines of business, as there would be a 
consistent expectation and policy across the different products offered 
by that plan. Therefore, we are proposing to require QHP issuers on the 
FFEs to make prior authorization decisions for non-drug items and 
services as expeditiously as the enrollee's health condition requires, 
but no later than 7 calendar days after receiving a standard request 
and no later than 72 hours after receiving an expedited request.
    For the prior authorization timeframes for drugs, we considered not 
taking any action. However, MA organizations require payers to respond 
to a prior authorization request no later than 72 hours for Part B 
drugs, and state Medicaid FFS programs are required to respond to prior 
authorization requests for covered outpatient drugs no later than 24 
hours. Therefore, we are proposing to require QHP issuers on the FFEs 
to make prior authorization decisions no later than 72 hours for 
standard requests and 24 hours for expedited requests for all drugs. We 
are proposing to require state Medicaid FFS programs, Medicaid managed 
care plans, and CHIP managed care entities to make prior authorization 
decisions for drugs within a timeframe that aligns with applicable 
existing decision timeframe requirements. We are also proposing to 
require state CHIP FFS programs to make prior authorization decisions 
no later than 24 hours for

[[Page 20040]]

prescription drugs for which FFP is available
4. Alternatives Considered for the Proposal To Adopt FHIR Standards for 
Prior Authorization-Related HIPAA Standard Transactions
    As an alternative to this proposal, HHS considered not taking any 
action and maintaining the X12N 270/271 and 278 transaction standards, 
respectively ``eligibility for a health plan'' transactions (when used 
to determine whether prior authorization is required) and ``referral 
certification and authorization'' transactions, currently required in 
regulation. Maintaining the status quo would avoid placing a new burden 
on sectors of the health care industry such as hospitals and physicians 
who have not yet implemented a FHIR API in their practice. These HIPAA 
covered entities would avoid the direct cost associated with adopting 
new health IT standards and implementing a FHIR API or upgrading their 
EHR or other health IT to support FHIR, which we describe in the cost 
section of this preamble. Maintaining the use of X12N 279/271 and 278 
transaction standards for prior authorization would also ensure 
continued alignment with other core operational uses of X12N standards, 
like eligibility verification and claims submission. While X12N 
standards are widely used across the industry, we note that there is a 
very low adoption rate of these X12N 278 transaction standards 
specifically for electronic prior authorization transactions, and this 
indicates to HHS that the standards are not serving the payers or 
providers as intended. Industry feedback indicates that the bi-
directional and real-time responses enabled by FHIR would reduce 
administrative burden associated with the batch-oriented X12N 
transaction standards, particularly in the ``back and forth'' 
communication between providers and payers. Based on the overwhelming 
movement of the health care industry towards FHIR standards, HHS 
concludes that proposing the adoption of the FHIR standard and 
applicable IGs for electronic prior authorization-related HIPAA 
transactions is the best option to support the long-term goal of 
interoperability.

E. Accounting Statement

F. Initial Regulatory Flexibility Analysis

    The IRFA requires agencies to analyze options for regulatory relief 
of small entities. For purposes of the IRFA, HHS estimates that many 
impacted payers and HIPAA covered entities are small entities, as that 
term is used in the IRFA, either by being nonprofit organizations or by 
meeting the Small Business Administration (SBA) definition of a small 
business. Small entities include small businesses, nonprofit 
organizations, and small governmental jurisdictions. Individuals and 
states are not included in the definition of a small entity. Executive 
Order 13272 requires that HHS thoroughly review rules to assess and 
take account of their potential impact on small businesses, small 
governmental jurisdictions, and small organizations (as mandated by the 
IRFA). If a proposed rule may have a significant economic impact on a 
substantial number of small entities, then the proposed rule must 
discuss steps taken, including alternatives considered, to minimize the 
burden on small entities. The IRFA does not define the terms 
``significant economic impact'' or ``substantial number.'' The SBA 
advises that this absence of statutory specificity

[[Page 20041]]

allows what is ``significant'' or ``substantial'' to vary, depending on 
the problem that is to be addressed in rulemaking, the rule's 
requirements, and the preliminary assessment of the rule's impact. 
Nevertheless, HHS typically considers a ``significant'' impact to be 3 
to 5 percent or more of the affected entities' costs or revenues and a 
``substantial number'' to be greater than 5 percent of impacted 
entities.
1. Objectives and Legal Basis
    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we did not propose or finalize policies that apply to drugs of 
any type because, as we discussed in the 2022 CMS Interoperability and 
Prior Authorization proposed rule and in the final rule, the processes 
and electronic standards for prior authorization of drugs differ from 
those for non-drug items and services. We also acknowledged that there 
are existing laws and regulations about prior authorization of certain 
drugs that may apply to impacted payers (such as the existing 
electronic prescribing requirements for covered Part D drugs in 42 CFR 
423.160) (87 FR 76240-76241 and 89 FR 8762). However, we received many 
public comments in response to the 2022 CMS Interoperability and Prior 
Authorization proposed rule, as well as additional feedback from 
providers, payers, and SDOs, indicating that while some prior 
authorization processes and standards for drugs currently exist, the 
health care industry would benefit from consistent requirements to 
ensure patients' timely access to drugs and a streamlined electronic 
prior authorization process that alleviates burden for providers and 
payers.
    We are proposing to require that impacted payers support electronic 
prior authorization for all drugs that require prior authorization. We 
are proposing two separate sets of standards to facilitate electronic 
prior authorization for all drugs: the HL7 FHIR standard (including 
associated FHIR IGs) as one set and three NCPDP standards (the NCPDP 
SCRIPT, NCPDP F&B, and NCPDP RTPB standards) as the other set. We are 
proposing to require impacted payers to expand their Prior 
Authorization API, finalized in the 2024 CMS Interoperability and Prior 
Authorization final rule (89 FR 8897), to incorporate drugs covered 
under a medical benefit. We are also proposing to require impacted 
payers (other than MA organizations) to support the proposed NCPDP 
standards for the electronic prior authorization of drugs covered under 
a pharmacy benefit.
    To fully incorporate drug coverage into the prior authorization 
policies finalized in the 2024 CMS Interoperability and Prior 
Authorization final rule, we are proposing to require state Medicaid 
and CHIP FFS programs, Medicaid managed care plans, CHIP managed care 
entities, and QHP issuers on the FFEs to respond to the provider with a 
specific reason for denying a prior authorization request for all 
drugs, regardless of whether they are covered under a medical or 
pharmacy benefit. We propose several timeframe modifications to align 
across programs. We are proposing to require state CHIP FFS programs to 
make decisions on prior authorization requests for prescription drugs 
for which the state receives FFP no later than 24 hours after receiving 
a prior authorization request. We propose to require QHP issuers on the 
FFEs to make decisions on prior authorization requests for non-drug 
items and services no later than 7 calendar days for standard requests 
and 72 hours for expedited requests. We are also proposing to require 
QHP issuers on the FFEs to make decisions on prior authorization 
requests for drugs no later than 72 hours for standard requests and no 
later than 24 hours for expedited requests. These proposed timeframes 
generally align with existing requirements for Part D sponsors in 42 
CFR 423.568(b) and in 42 CFR 423.572(a).
    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we finalized requirements for impacted payers to report on their 
websites certain prior authorization metrics for non-drug items and 
services (89 FR 8889 and 8890). We are now proposing six new metrics: 
four new metrics about prior authorization denials after an extended 
timeframe and appeals for non-drug items and services and two new 
metrics about prior authorization approvals after an extended timeframe 
and appeals for non-drug items and services for expedited prior 
authorization requests only. Similarly, we are proposing to require 
impacted payers to publicly post on their websites a set of metrics on 
prior authorizations for all drugs (excluding covered Part D drugs for 
MA-PD plans).
    To support implementation of the policies we propose to require 
impacted payers to report their API endpoints for each of the required 
APIs to CMS. In response to the 2022 CMS Interoperability and Prior 
Authorization proposed rule, we received numerous comments from the 
public indicating that a centralized directory of API endpoints would 
be necessary to unlock the full potential of our electronic data 
exchange policies and reduce administrative burden (89 FR 8932).
    Under the Administrative Simplification provisions of HIPAA, in 
Title XI, Part C of the Act, HHS is proposing to adopt the FHIR 
standard and certain associated IGs as the standards for dental, 
professional, and institutional ``referral certification and 
authorization'' transactions and ``eligibility for a health plan'' 
transactions associated with prior authorization for all HIPAA covered 
entities. Specifically, in addition to the FHIR standard, HHS is 
proposing to adopt the US Core, SMART App Launch, CRD, DTR, and PAS IGs 
in place of the adopted versions of the X12N 278 transaction standard 
in 45 CFR 162.1302 and the existing X12N 270/271 transaction standard 
in 45 CFR 162.1202 for transactions related to prior authorization. 
Additionally, HHS is proposing to adopt the CDex IG in 45 CFR 
162.1302(g)(2)(vii) as the attachment standard for prior authorization 
transactions. We seek comment on these proposals and their impact on 
small entities.
2. Impacted Payers
    We refer to MA organizations, state Medicaid and CHIP FFS programs, 
Medicaid managed care plans, CHIP managed care entities, and QHP 
issuers on the FFEs as ``impacted payers,'' as we did in the 2024 CMS 
Interoperability and Prior Authorization final rule (89 FR 8758). In 
this proposed rule, the 341 impacted payers (also referred to as parent 
organizations offering impacted health plans when discussing 
calculations) would perform system updates to expand the capability of 
the required APIs.\453\ Specifically, the rule proposes to require that 
impacted payers add certain information for prior authorizations or 
expand the capabilities of the Prior Authorization API to accommodate 
prior authorizations for drugs covered under a medical benefit. 
Additionally, we propose that the impacted payers would be responsible 
for developing and submitting reports regarding API usage or making 
data about prior authorization decisions for drugs available on public 
websites. Furthermore, if this proposed rule is finalized, the 341 
impacted payers would be required to implement and maintain APIs that 
conform to standards adopted by the Secretary in 45 CFR 170.215. We 
refer to Table 3 in section II.A. of this proposed rule, where we list 
the standards and specifications required for each API.

[[Page 20042]]

Impacted payers would also be required to implement the FHIR IGs that 
were previously recommended in the 2024 CMS Interoperability and Prior 
Authorization final rule. A subset of impacted payers would have to 
create or update policies and procedures for prior authorization 
decisions to meet the timeframe proposals and to support electronic 
prior authorization for drugs using the proposed NCPDP standards 
adopted by the Secretary in 45 CFR 170.205(b), (c), and (u). Lastly, we 
propose that all impacted payers would be required to annually report 
their API endpoint information to CMS. Impacted payers described in 
this proposed rule would be classified under the NAICS code 524114 
(Direct Health and Medical Insurance Carriers), which has a $47 million 
threshold for ``small size'' per the SBA.\454\

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

a. Medicare Advantage
    Each year, MA organizations estimate costs for the upcoming plan 
year and then submit bids and proposed PBPs to CMS. These bids project 
payments to hospitals, providers, and staff for covered benefits, as 
well as the cost of plan administration and profits. Because the API 
requirements proposed in this rule would apply to every MA plan and 
each MA plan must furnish at least the Medicare Part A and Part B 
benefits, we assume that the cost of the API would be built into the 
administrative component of the basic benefit bid. These bids in turn 
determine one component of the payments of the Medicare Trust Fund to 
the MA organizations who reimburse providers and subcontractors for 
their services. A second component of the Trust Fund payment to MA 
organizations are the rebates, which are a portion of the difference 
between the basic benefit bid compared to an administratively-set 
benchmark for the MA plan's service area (currently, based on our past 
and projected experience, rebates vary by plan and are approximately 66 
percent). If the bid is below the benchmark, CMS pays an amount equal 
to the standard bid of the MA organization. However, if the bid is 
above the benchmark, CMS pays the portion of the cost up to the 
benchmark and the MA organization bears the extra cost and must charge 
enrollees a premium for the remaining amount, as set forth in section 
1854 of the Act. As the cost of providing services by these payers is 
covered by a combination of government funding and in some cases by 
enrollee premiums, MA and PDPs are not expected to incur burdens or 
losses because the private companies' costs are being supported by the 
government and enrolled beneficiaries. This lack of expected burden 
applies to both large and small MA health plans. Any MA health plans 
that are considered ``small'' would be expected to include the costs of 
compliance with the proposed regulations in their bids, thus avoiding 
additional burden, since the cost of complying with any regulation is 
funded by payments from the government and, if applicable, enrollee 
premiums. Historically, at most 2 percent of plans bid above the 
benchmark, and they contain roughly 1 percent of all plan enrollees.
    Table 35 reports the percentage of MA organizations bidding above 
the benchmark and the percentage of affected enrollees in recent years. 
This table reports aggregates of proprietary bid data collected by 
OACT. As shown in Table 35, the percentage of plans incurring 
additional costs by bidding above the benchmark is 0.11 percent in 2024 
and 0.07 percent in 2025, while the CMS threshold for what constitutes 
a significant impact for purposes of the IRFA is 3 to 5 percent. Since 
at least 99 percent of MA organizations bid below the benchmark in 
recent years, we estimate that the federal government fully pays these 
MA organizations their projected costs for providing services to 
enrollees for the coming year. The preceding analysis shows that MA 
plans, whether small or large entities, are not significantly affected 
by this proposed rule since the vast majority (all but at most 1 
percent) will have their costs subsidized by the federal government and 
would not be materially impacted. Consequently, we conclude that, among 
MA plans, the impact of the cost of these proposals would not be 
significant for the purposes of the IRFA.

b. Medicaid and CHIP
    Title XIX of the Act established the Medicaid program as a federal-
state partnership to provide and finance medical assistance to 
specified groups of eligible individuals. States claim federal matching 
funds quarterly based on their program expenditures. Medicaid managed 
care plans and CHIP managed care entities reflect a somewhat 
consolidated market with a mix of for-profit, non-profit, and 
government plans. 2022 survey data suggest that 16 managed care firms 
(including Aetna, Centene, United Health Care, and others) were 
responsible for approximately 63 percent of the market. The remaining 
36 percent of managed care enrollment reflects local/regional managed 
care companies,\455\ which are more likely to be considered small, 
though data on their size distribution by annual receipt size is 
limited. However, since Medicaid

[[Page 20043]]

managed care plans and CHIP managed care entities receive 100 percent 
capitation from the state, we expect that the projected costs 
associated with the provisions of this proposed rule, if finalized, 
will be included in their capitation rates. Consequently, we assert 
that there will be no substantial impact on a significant number of 
these entities for the purposes of this IRFA.

c. QHP Issuers on the Federally-Facilitated Exchanges
    For the purposes of this IRFA, CMS evaluated health insurance 
issuers categorized under NAICs code 524114 (Direct Health and Medical 
Insurance Carriers). Based on the latest available SUSB data, 1,071 
total firms fall under code 524114. According to SBA size standards, 
entities with average annual receipts of $47 million or less would be 
considered small entities in this category.\456\ Consistent with the 
analysis published in the ``Patient Protection and Affordable Care Act, 
HHS Notice of Benefit and Payment Parameters for 2027; and Basic Health 
Program'' proposed rule (91 FR 6292), which appeared in the Federal 
Register on February 11, 2026, we assume that few, if any, insurance 
companies underwriting comprehensive health insurance policies 
available on the FFE (in contrast, for example, to travel insurance 
policies or dental discount policies) fall below these SBA size 
thresholds. CMS examined the premium revenue data from the MLR annual 
report submissions for the 2023 MLR reporting year and approximately 84 
out of 479 issuers of health insurance coverage nationwide have a total 
premium revenue of $47 million or less.\457\ Furthermore, approximately 
80 percent of these small issuers belong to non-small holding groups 
based on the total premium revenue of all associated subsidiaries 
available in the MLR data. Many, if not all, of these holding group 
companies are likely to have other non-health lines of business in 
addition to health plan premium revenue that likely result in their 
total revenues exceeding $47 million.\458\ Therefore, CMS concludes 
that the QHP issuer on the FFEs population impacted by these proposed 
policies is unlikely to include small entities and can be excluded from 
this IRFA.

3. HIPAA Covered Entities
    In addition to proposed requirements for ``impacted payers,'' which 
largely comprise of government health plans within NAICS category 
524114, this proposed rule would also impose direct requirements on 
HIPAA covered entities to replace their existing X12N 278 transaction 
standard with FHIR standards to build a FHIR API. Such covered entities 
include health care providers (including individual providers and 
clinics who transmit information in an electronic form), hospitals, all 
health plans, and health care clearinghouses. NAICS is used in the 
United States, Canada, and Mexico to classify businesses by industry. 
While there is no distinction between small and large businesses among 
the NAICS categories, the SBA develops size standards for each NAICS 
category. For the purposes of HHS's analysis, HHS relies on a 
combination of NAICS codes (hospitals NAICS code 622 and physicians 
NAICS code 6211) to approximate data on the health care providers that 
are small entities. HHS used the methodology described in the 2022 
HIPAA Standards for Health Care Attachments proposed rule RIA to 
evaluate the impact on hospitals (NAICS code 622), clearinghouses 
(NAICS code 522320), physicians (NAICS code 6211), health plans (NAICS 
code 524114), and all other support services (NAICS code 561990) which 
encompasses EHR vendors. The SBA Standard size entity threshold for 
each category is described in Table 36. We used the most recent revenue 
data available from the 2022 SUSB from the Census Bureau to determine 
the number of small entities and their revenue. HHS considered 
including the 2023 Nonemployer Statistics (NES) data from the Census 
Bureau to supplement the SUSB data on small providers in particular. 
However, considering the industries impacted by this proposal and the 
nature of the health care services which most frequently require prior 
authorization, HHS is hesitant to include data on provider businesses 
with no employees in the total count of small provider entities. It is 
unclear to HHS what proportion of providers (Physicians) have no 
employees and would also provide items and services subject to prior 
authorization and manage those prior authorization requests themselves. 
HHS requests comment from providers on the inclusion of NES data in 
this IRFA analysis and if self-employed providers with no employees 
could be expected to be impacted by the proposed policy. As noted in 
the cost analysis section of this preamble, HHS is hesitant to project 
that all small providers would make the business and financial decision 
to upgrade their EHR product to support the FHIR standards for prior 
authorization. The decision to adopt FHIR would vary depending on the 
volume of prior authorization each business requests among other 
factors.

[[Page 20044]]

[GRAPHIC] [TIFF OMITTED] TP14AP26.317

    HHS also encountered uncertainties in measuring the potential 
impact of this proposal on clearinghouses (NAICS code 522320) and all 
other support services (NAICS code 561990), which encompasses EHR 
vendors, that could fall under the small entity threshold. HHS notes 
that in 2020, the national clearinghouse association, Cooperative 
Exchange, indicated its 23 member companies represent over 90 percent 
of the clearinghouse industry.\459\ HHS is uncertain if this proposal 
would materially impact any small clearinghouse entities and seeks 
comment from the clearinghouse industry on the potential impacts of 
this proposal on small clearinghouses. Finally, approximately 10,484 
other support service entities qualify as small entities, which equate 
to about 6.65 percent of the regulated small businesses across the 5 
industries in this analysis. The ``other support service'' category is 
used by HHS to represent plan management system vendors and EHR 
technology system vendors, though it includes many types of technology 
vendors outside of the healthcare industry. Counting the affected plan 
management system and EHR vendor entities separately is complicated, in 
part because they are increasingly integrated. A health care provider 
entity's plan management system and EHR systems may be bundled into one 
product offering, semi-integrated affiliated systems, or entirely 
independent systems offered by separate vendors. The 2022 Census Bureau 
SUSB dataset does not provide firm-level counts for health care 
industry-specific technology vendors.\460\ For this reason, HHS relies 
on industry reporting from 2024 and 2025, which suggests that 
approximately 500 vendors are offering an EHR product and that several 
large vendors dominate the EHR market.\461\ Epic, Oracle Cerner, and 
Meditech are the three biggest EHR vendors among hospitals, making up 
nearly 75 percent of the market share combined.\462\ Epic, Oracle 
Cerner, and athenahealth, Inc. represent the biggest vendors among 
clinicians, with approximately 82 percent of the market share 
combined.463 464 Due to the lack of specific detail on how 
many entities within the other support service category are EHR vendors 
and given that the majority of providers using an EHR contract with a 
large entity, as explained in the Uncertainties analysis in section 
V.C.2.a.(1).(d). of this proposed rule, HHS is uncertain if small EHR 
entities will be materially impacted by the proposals in this proposed 
rule. HHS invites comment on this assumption and requests feedback from 
EHR vendors, particularly those considered small, on the potential 
impacts of these policies on small EHR vendor companies.

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

    Based on the SBA size threshold described in Table 36, HHS analyzed 
the revenue for hospitals, physicians, and direct health insurance 
plans which met the SBA criteria for small entities and their 
anticipated change in revenue, illustrated in Table 37. To conduct this 
revenue test, HHS used the total count of firms considered small based 
on the latest 2022 SUSB data (143,743). Then, HHS calculated the 
percentage of these small firms that fall into size ranges by receipt 
(``% of Small Firms'' column in Table 37). These percentages are 
applied to the average revenue for all small entities, which yields the 
average revenue for each firm size. The average revenue for each firm 
size is then divided by the annualized cost of the proposed rule per 
firm and reflected as a percentage. When the annualized net primary 
cost estimates were determined, there were $40.88 million net 
annualized costs for the industries overall.\465\ The net annualized 
costs for this proposed rule are $40.88 million, meaning each of the 
143,743 small businesses incur a net annualized cost of $284.40, 
regardless of their size by receipts. This resulting percentage 
(``Revenue Test'' column in Table 37) is the anticipated change in 
revenue for small firms due to the proposed rule. As a measure of 
significant economic

[[Page 20045]]

impact on a substantial number of small entities, HHS uses a change in 
revenue of more than 3 percent and presents this analysis in Table 37.
---------------------------------------------------------------------------

    \465\ The total cost $40.88 million includes the total 
annualized cost of the proposed policies and the annualized 
regulatory review cost ($40.68 + $0.20 = $40.88).
---------------------------------------------------------------------------

    HHS calculated the percentage of revenue represented by the primary 
estimates of small entities earning less than $50,000,000 in receipts 
annually. None of the included buckets exceeded the 3 percent of the 
revenue threshold, and all of the revenue test results reflect less 
than 1 percent revenue impact.

4. Alternatives for Small Entities
    In an effort to anticipate the needs of small entities, CMS 
considered options for viable alternatives that adapt the proposed 
policies in this proposed rule and tailor them to small businesses. 
These alternatives attempt to balance the need for broad adoption of 
the proposals to achieve improved interoperability and an 
acknowledgement that small businesses are typically less resourced. The 
alternative options fall into two main categories: delayed compliance 
and exemption criteria. Some of these alternatives are already 
incorporated into the proposals of this rule but could be expanded to 
other provisions to better accommodate small businesses, while others 
are novel and have not yet been introduced.
a. Delayed Compliance
    HHS is proposing to adopt a modified standard for two HIPAA 
Administrative Simplification transactions, the ``referral 
certification and authorization'' transaction in 45 CFR part 162, 
subpart M and the ``eligibility for a health plan'' transaction in 45 
CFR part 162, subpart L. HHS proposes to adopt, in 45 CFR 162.1302(g), 
the FHIR standard, US Core IG, SMART App Launch IG, CRD, DTR, PAS, and 
CDex IGs as the specifications that compose the proposed transaction 
standard. In addition, in 45 CFR 162.1202(f)(2), HHS is proposing to 
adopt the FHIR standard, the US Core IG, SMART App Launch IG, and CRD 
IG as the specifications that compose the proposed transaction standard 
for ``eligibility for a health plan'' transactions, when used to 
determine whether prior authorization is required. If finalized as 
proposed, HIPAA covered entities would be required to comply with these 
transaction standards no later than 24 months from the effective date 
of a final rule, except for small health plans, defined in 45 CFR 
160.103 as those with annual receipts of $5 million or less, for which 
the compliance date would be 36 months from the effective date of a 
final rule. The proposed delayed compliance date for small health plans 
would allow these health plans an additional year to prepare to use the 
FHIR standards for those transactions. This same principle could be 
applied to entities considered ``small'' for other provisions in this 
proposed rule, including the proposal for impacted payers to expand 
their Prior Authorization API to incorporate drugs covered under a 
medical benefit and that impacted payers (other than MA organizations) 
support the NCPDP standards for the electronic prior authorization of 
drugs covered under a pharmacy benefit. An additional 12 months of 
implementation time could support small entities in preparing for the 
technical requirements of these proposals and distribute the estimated 
per-entity cost of $12,500 associated with adopting the standard over 1 
year. This redistribution of cost over 2 years could result in small 
entities saving approximately $6,250 in the first year of 
implementation. However, as discussed in section V.F.2. of this 
proposed rule, the majority of impacted payers likely do not qualify as 
small, so the impact of this alternative is uncertain.
b. Extensions and Exceptions
    CMS is proposing a process for state Medicaid and CHIP FFS programs 
to request from CMS extensions to allow additional time to implement 
the Prior Authorization API, meet the proposed requirement to 
incorporate drugs covered under a medical benefit into the Prior 
Authorization API, and/or to support the NCPDP standards for electronic 
prior authorization of drugs covered under a pharmacy benefit. The 
updated proposals would replace the existing process by which states 
can request an exemption from the requirement to implement the Prior 
Authorization API finalized in the 2024 CMS Interoperability and Prior

[[Page 20046]]

Authorization final rule. CMS is also proposing a process to allow QHP 
issuers on the FFEs to apply for an exception from the proposed 
requirement to support the NCPDP standards for electronic prior 
authorization of drugs covered under a pharmacy benefit in limited 
circumstances. A similar exception process, wherein an impacted payer 
provides justification based on certain criteria for not being able to 
meet the requirement and submits a plan to come into compliance, might 
be adapted and provided specifically to small entities that participate 
in any CMS program. If granted an exception, this alternative could 
save small entities between $12,500-$57,511 in first-year 
implementation costs based on the estimated burden for each of these 
proposals. However, this process would still generate administrative 
and reporting burden for the small entities as they would need to 
justify their exception. Furthermore, patients that have coverage 
through those small entities and providers in their networks would not 
be able to benefit from the burden reduction we expect our proposals to 
catalyze.
5. Identifying Duplication
    In the 2024 CMS Interoperability and Prior Authorization final 
rule, we finalized requirements for impacted payers to improve the 
electronic exchange of health care information, not just with patients, 
but also with their providers and other payers. We finalized 
requirements for impacted payers to implement and maintain a Prior 
Authorization API that streamlines the prior authorization process 
between providers and payers.\466\ We additionally finalized general 
process requirements for prior authorization, such as requiring MA 
organizations, state Medicaid and CHIP FFS programs, Medicaid managed 
care plans, and CHIP managed care entities to respond to prior 
authorization requests for non-drug items and services within certain 
timeframes. Many of the policies proposed in this rule build upon and 
align with those finalized in the 2024 CMS Interoperability and Prior 
Authorization final rule particularly because they apply to the same 
population of impacted payers and reference the same electronic data 
transmission standards. However, CMS confirms that the proposed 
requirements in this rule do not duplicate efforts of this previous 
rulemaking, but rather, they build upon and refine them to ensure that 
drugs are accounted for in the improvements being made to the prior 
authorization process, standards, and data reporting.
---------------------------------------------------------------------------

    \466\ See 42 CFR 422.122(b) for MA organizations, 42 CFR 
431.80(b) for state Medicaid FFS programs, 42 CFR 457.732(b) for 
state CHIP FFS programs, through cross reference to 42 CFR 431.80(b) 
in 42 CFR 438.242(b)(7) for Medicaid managed care plans, through 
cross reference to 42 CFR 438.242 in 42 CFR 457.1233(d) for CHIP 
managed care entities, and 45 CFR 156.223(b) for individual market 
QHP issuers on the FFEs.
---------------------------------------------------------------------------

    In addition, HHS reiterates that there is no redundancy in these 
proposals and the provisions finalized in the HIPAA Standards for 
Health Care Attachments final rule (91 FR 14350). In the HIPAA 
Standards for Health Care Attachments proposed rule, HHS proposed 
standards for ``health care attachments'' transactions, which would 
support both health care claims and prior authorization transactions, 
and a standard for electronic signatures to be used in conjunction with 
health care attachments transactions. However, in the HIPAA Standards 
for Health Care Attachments final rule, HHS adopted an attachment 
standard only for claims transactions and did not finalize an 
attachment standard for prior authorization transactions. Specifically, 
the HIPAA Standards for Health Care Attachments final rule does not 
adopt any modifications to prior authorization transactions or finalize 
any conflicting prior authorization transaction requirements that would 
overlap with this proposed rule. HHS concludes that there is no 
duplication or conflict of the requirements in this proposed rule and 
other recent rulemakings impacting similar populations and sectors of 
the industry.
6. Conclusion and Request for Comment
    CMS concludes that the proposals relevant to impacted payers do not 
produce a significant economic impact on a substantial number of 
impacted payers that are small entities. CMS seeks comment on the 
assumptions related to the number of MA organizations, state Medicaid 
and CHIP FFS programs, Medicaid managed care plans, CHIP managed care 
entities, and QHP issuers on the FFEs that could be considered small 
businesses, small governmental jurisdictions, or small organizations. 
HHS assumes that only a subset of small HIPAA covered entities would be 
economically impacted by the proposed policy and assumes that only 
those represented in the SUSB dataset, that is, those with employees, 
would be impacted by these proposals. CMS and HHS solicit comment 
specifically from HIPAA covered entities and small businesses 
associates in the health care and health technology industries on the 
impacts of the various proposals in this proposed rule. We request 
comment specifically on how the proposals increase or decrease 
administrative burden for small HIPAA covered entities and business 
associates, as well as feedback on mitigation strategies.
    For the purposes of the IRFA analysis, HHS concludes that there is 
not a significant impact on small entities. As a measure of significant 
economic impact on a substantial number of small entities, HHS uses a 
change in revenue of more than 3 percent. As illustrated by the revenue 
test in Table 37, none of the small firm sizes approached the 3 percent 
threshold.
    In addition, section 1102(b) of the Act requires HHS to prepare an 
RIA 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 603 of the IRFA for proposed rules. For 
purposes of section 1102(b) of the Act, HHS defines a small rural 
hospital as a hospital that is located outside of a Metropolitan 
Statistical Area for Medicare payment regulations and has fewer than 
100 beds. HHS is not preparing an analysis for section 1102(b) of the 
Act because HHS has determined that the Secretary may certify that this 
proposed rule would not have a significant impact on the operations of 
a substantial number of small rural hospitals.

G. Unfunded Mandates Reform Act

    Section 202 of UMRA also requires that agencies assess anticipated 
costs and benefits before issuing any rule whose mandates will require 
spending more in any one year than threshold amounts in 1995 dollars, 
updated annually for inflation. In 2026, this threshold is 
approximately $193 million. This proposed rule will not impose mandates 
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 any one year.

H. Federalism

    Executive Order 13132 establishes certain requirements that an 
agency must meet when it promulgates a proposed rule that imposes 
substantial direct requirement costs on state and local governments, 
preempts state law, or otherwise has federalism implications. This 
proposed rule will not have a substantial direct effect on state or 
local governments, preempt state law, or otherwise have a federalism 
implication.

[[Page 20047]]

I. Executive Order 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 proposed rule, if 
finalized as proposed, is expected to be considered an Executive Order 
14192 regulatory action. We estimate that this final rule will generate 
$31.78 million in annualized cost at a 7 percent discount rate, over a 
perpetual time horizon.
    By the provisions of Executive Order 12866, this proposed rule has 
been reviewed by OMB.

VI. Response to Comments

    Because of the large number of public comments we usually receive 
on Federal Register documents, we cannot acknowledge or respond to them 
individually. We will consider all comments we receive by the date and 
time specified in the DATES section of the preamble, and when we 
proceed with a subsequent document, we will respond to the comments in 
the preamble to that document.

interest because the QHP issuer needs additional medical evidence from 
another provider or from the enrollee in order to issue a decision.

other non-routine circumstances and is in the provider's or enrollee's 
interest.
