SUPPLEMENTARY INFORMATION:

I. Executive Summary

A. Purpose

    The primary purpose of this final rule is to amend the regulations 
for the Medicare Advantage (Part C) program, Medicare Prescription Drug 
Benefit (Part D) program, Medicare Cost Plan Program, and Programs of 
All-Inclusive Care for the Elderly (PACE). This final rule includes a 
number of new policies that will improve these programs for contract 
year 2026, as well as codify existing Part C and Part D sub-regulatory 
guidance.
    In this final rule, CMS codifies certain Part D requirements from 
the Inflation Reduction Act of 2022 (IRA). Specifically, this rule 
codifies the IRA's vaccine and insulin cost-sharing requirements and 
codifies the program instruction for the Medicare Prescription Payment 
Plan program. Additionally, CMS is finalizing two IRA-related 
provisions that are needed to help ensure that selected drugs with 
maximum fair prices (MFPs) in effect under the Negotiation Program are 
available to beneficiaries at the point of dispensing and that the MFPs 
are effectuated for dispensing entities timely.

B. Summary of the Major Provisions

1. Vaccine Cost-Sharing Changes
    We are finalizing as proposed this provision to implement section 
11401 of the Inflation Reduction Act of 2022 (IRA), which amends 
section 1860D-2 of the Social Security Act (the Act) to require that, 
effective for plan years beginning on or after January 1, 2023, the 
Medicare Part D deductible shall not apply to, and there is no cost 
sharing for, an adult vaccine recommended by the Advisory Committee on 
Immunization Practices (ACIP) covered under Part D.
2. Insulin Cost-Sharing Changes
    We are finalizing as proposed this provision to implement section 
11406 of the IRA, which amends section 1860D-2 of the Act to require 
that, effective for plan years beginning on or after January 1, 2023, 
the Medicare Part D deductible shall not apply to covered insulin 
products, and the Part D cost-sharing amount for a one-month supply of 
each covered insulin product must not exceed the statutorily defined 
``applicable copayment amount'' for all enrollees. The applicable 
copayment amount for 2023, 2024, and 2025 is $35. For 2026 and each 
subsequent year, in accordance with the statute, we are finalizing 
that, with respect to a covered insulin product covered under a 
prescription drug plan (PDP) or a Medicare Advantage prescription drug 
(MA-PD) plan prior to an enrollee reaching the annual out-of-pocket 
threshold, the ``covered insulin product applicable cost-sharing 
amount'' is the lesser of--
    <bullet> $35;
    <bullet> An amount equal to 25 percent of the maximum fair price 
established for the covered insulin product in accordance with Part E 
of title XI; or
    <bullet> An amount equal to 25 percent of the negotiated price, as 
defined in Sec.  423.100, of the covered insulin product under the PDP 
or MA-PD plan.
3. Medicare Prescription Payment Plan
    We proposed regulatory changes to codify agency guidance 
implementing section 11202 of the IRA, which establishes the Medicare 
Prescription Payment Plan and requires each PDP sponsor offering a 
prescription drug plan and each MA organization offering an MA-PD plan 
to provide any enrollee of such plan, including an enrollee who is 
subsidy eligible, the option to elect with respect to a plan year to 
pay cost sharing under the plan in monthly amounts that are capped. 
Specifically, we proposed to add new Sec.  423.137 establishing 
requirements for the Medicare Prescription Payment Plan, add several 
new Part D required materials and content at Sec.  423.2267, add 
Medicare Prescription Payment Plan information to the list of required 
content for Part D sponsor websites at Sec.  423.2265, and add the 
Medicare Prescription Payment Plan to the list of Part D requirements 
waived for the

[[Page 15793]]

Limited Income Newly Eligible Transition (LI NET) program at Sec.  
423.2536. We also proposed to codify the requirements we established in 
the Final CY 2025 Part D Redesign Program Instructions for the 
treatment for Medical Loss Ratio (MLR) purposes of Medicare 
Prescription Payment Plan unsettled balances for 2026 and subsequent 
years.
    We are finalizing all requirements for 2026 and future years as 
proposed with a few exceptions:
    <bullet> Modified the timing and content requirements for the 
renewal notice at Sec.  423.137(d)(10)(iv).
    <bullet> Modified the requirements for the telephonic notice of 
election approval at Sec.  423.137(d)(10)(ii).
    <bullet> Modified the requirements for voluntary termination 
effective date at Sec.  423.137(f)(2)(i)(A)(1).
    <bullet> Modified timing requirements for the involuntary 
termination notice at Sec.  423.137(f)(2)(ii)(D)(1).
    <bullet> Modified Sec.  423.137(i)(2) to state that Part D plan 
sponsors should require long-term care pharmacies to provide the 
``Medicare Prescription Payment Plan Likely to Benefit Notice'' to the 
Part D enrollee (or their authorized representative) at the time of the 
pharmacy's typical enrollee cost-sharing billing process.
    <bullet> Modified Sec.  423.137(m)(1) to exempt dual eligible 
special needs plans (D-SNPs) from certain general outreach and 
education requirements.
    <bullet> Modified Sec.  423.137(j)(7) to remove the requirements 
for Part D sponsors to ensure that pharmacies are prepared to provide 
information regarding out-of-pocket (OOP) costs for the Medicare 
Prescription Payment Plan to a participant at the point of sale (POS).
4. Improving Experiences for Dually Eligible Enrollees
    Dually eligible individuals face fragmentation in many parts of the 
health care system, including their experiences as enrollees of 
Medicare and Medicaid managed care plans. One way in which we seek to 
address such fragmentation is through policies that integrate care for 
dually eligible individuals. ``Integrated care'' refers to delivery 
system and financing approaches that (1) maximize person-centered 
coordination of Medicare and Medicaid services; (2) mitigate cost-
shifting incentives between the two programs; and (3) create a seamless 
experience for dually eligible individuals. We are finalizing new 
Federal requirements for D-SNPs that are applicable integrated plans 
to: (1) have integrated member identification (ID) cards that serve as 
the ID cards for both the Medicare and Medicaid plans in which an 
enrollee is enrolled; and (2) conduct an integrated health risk 
assessment (HRA) for Medicare and Medicaid, rather than separate HRAs 
for each program. We are also finalizing provisions to codify 
timeframes for special needs plans to conduct HRAs and individualized 
care plans (ICPs) and prioritize the involvement of the enrollee or the 
enrollee's representative, as applicable, in the development of the 
ICPs.
5. Timely Submission Requirements for Prescription Drug Event (PDE) 
Records
    We are finalizing as proposed PDE submission timeframes similar to 
those timeframes described in the October 2011 guidance on the timely 
submission of PDE records and refer to those timeframes as the General 
PDE Submission Timeliness Requirements. CMS is codifying PDE submission 
timeframes that initial PDE records are due within 30 calendar days 
following the date the claim is received by the Part D sponsor (or its 
contracted first tier, downstream, or related entity). Adjustment and 
deletion PDE records are due within 90 calendar days following 
discovery of the issue requiring a change to the PDE. Resolution of 
rejected PDE records are due within 90 calendar days following the 
receipt of rejected record status from CMS. In addition, we are 
finalizing as proposed regulatory changes at Sec.  423.325(b) to 
establish a distinct PDE submission timeliness requirement for selected 
drugs, in which CMS requires that a Part D sponsor must submit initial 
PDE records for selected drugs (as described at section 1192(c) of the 
Act) within 7 calendar days from the date the Part D sponsor (or its 
contracted first tier, downstream, or related entity) receives the 
claim.
6. Medicare Transaction Facilitator Requirements for Network Pharmacy 
Agreements
    We are finalizing as proposed our proposal to amend Sec.  423.505 
by adding paragraph (q), requiring that Part D sponsors' network 
participation agreements with contracting pharmacies, including any 
contracts with any first tier, downstream, and related entities require 
such pharmacies to be enrolled in the Medicare Drug Price Negotiation 
Program's (``Negotiation Program'') Medicare Transaction Facilitator 
Data Module (``MTF DM'') and that such pharmacies certify the accuracy 
and completeness of their enrollment information in the MTF DM. We 
believe the inclusion of the requirement for Part D sponsors' network 
pharmacies to be enrolled in the MTF DM that will be added to Part D 
sponsors' network contracts with pharmacies will facilitate continued 
beneficiary access to selected drugs that are covered Part D drugs, 
promote access to negotiated MFPs under the Negotiation Program for 
both beneficiaries and dispensing entities, and help ensure accurate 
Part D claims information and payment.
7. Clarifying MA Organization Determinations To Enhance Enrollee 
Protections in Inpatient Settings
    We are finalizing our proposal to clarify that the definition of 
``organization determination'' includes MA plan decisions made 
concurrent to the enrollee's receipt of services. We are also 
finalizing our proposals to codify existing guidance that requires 
plans give a provider notice of a coverage decision, in addition to the 
enrollee, whenever the provider submits a request on behalf of an 
enrollee, as well as our proposal to modify existing regulations to 
clarify that an enrollee's liability to pay for services cannot be 
determined until an MA organization has made a claims payment 
determination. Lastly, we are finalizing our proposal to restrict 
plans' ability to use information gathered after the inpatient 
admission has taken place when reviewing the appropriateness of the 
admission itself.
8. Risk Adjustment Data Updates
    We are finalizing a series of provisions related to risk adjustment 
data updates. First, we are finalizing a technical change to the 
definition of Hierarchical Condition Categories (HCCs) to remove the 
reference to a specific version of the ICD, while maintaining a 
reference to the ICD in general, to keep the HCC definition in Sec.  
422.2 current as newer versions of the ICD become available and are 
adopted by the Secretary, as well as substituting the terms ``disease 
codes'' with ``diagnosis codes'' and ``disease groupings'' with 
``diagnosis groupings'' to be consistent with ICD terminology. 
Additionally, we are codifying the longstanding practice of requiring 
the collection and mandatory submission of risk adjustment data by PACE 
organizations (at Sec.  460.180(b)) and Cost plans (at Sec.  
417.486(a)).

                                         paying OOP costs at the point of sale (POS). We are finalizing all
                                         requirements for 2026 and future years as proposed with a few exceptions:

                                         at Sec.   423.325(b) to establish a distinct PDE submission timeliness
                                         requirement for selected drugs, in which CMS requires that a Part D sponsor
                                         must submit initial PDE records for selected drugs (as described at section
                                         1192(c) of the Act) within 7 calendar days from the date the Part D sponsor
                                         (or its contracted first tier, downstream, or related entity) receives the
                                         claim.

                                         information provided by such pharmacies in the MTF DM is accurate,
                                         complete, and up to date.

                                         Additionally, we are codifying the longstanding practice of requiring the

                                         organizations (at Sec.   460.180(b)) and Cost plans (at Sec.   417.486(a)).

D. Publication of the Proposed Rule, Responding to Public Comments, and 
the Finalization of Proposed Provisions

    The proposed rule titled ``Medicare and Medicaid Programs; Contract 
Year 2026 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'' appeared 
in the December 10, 2024 Federal Register (89 FR 99340) (hereinafter 
referred to as the ``Contract Year 2026 proposed rule'').
    In response to the Contract Year 2026 proposed rule, we received 
approximately 31,227 timely pieces of correspondence containing 
multiple comments on the proposed rule. We note that some of the public 
comments were outside of the scope of the proposed rule. These out-of-
scope public comments are not addressed in this final rule. Summaries 
of the public comments within the scope of the proposed rule and our 
responses to those public comments are set forth in the various 
sections of this final rule under the appropriate heading. We are 
finalizing several of the provisions from the proposed rule, some with 
minor clarifications based on comments received. In this final rule, we 
are not summarizing or responding to comments received with respect to 
the provisions of the proposed rule that we are not addressing or 
finalizing at this time. Rather, as appropriate, and if applicable, we 
will address those comments at a later time in a subsequent rulemaking 
document.
    With respect to the section of the proposed rule entitled 
``Formulary Inclusion and Placement of Generics and Biosimilars,'' CMS 
continues to encourage Part D sponsors to prioritize formulary 
placement for generics and biosimilars through favorable tier placement 
relative to branded and reference products. As we noted in the proposed 
rule, CMS currently conducts an extensive formulary review process to 
ensure Part D sponsors provide an adequate formulary consistent with 
Sec.  423.120(b)(2). In addition, as also noted in the proposed rule, 
we have been monitoring beneficiary access to generics and biosimilars, 
utilization of multi-source brand drugs when generics are available, 
and situations where the brand drug is situated more favorably in 
comparison to the generic with regard to tiering and UM, and we will 
continue to do so. While we are not adding the additional step in our 
formulary review process described in the proposed rule, the policy 
reminders and clarifications with respect to Part D plan formularies 
providing broad access to generics and biosimilars as part of a cost-
effective drug utilization program still apply. CMS may consider 
codifying additional requirements regarding formularies in future 
rulemaking if necessary.
    CMS will continue to review regulations and policies in the 
Medicare program and make necessary and appropriate changes to ensure 
consistency with the Executive Order 14192, ``Unleashing Prosperity 
Through Deregulation.. Such regulations and policies currently under 
review include but are not limited to--
    <bullet> Health Equity Index Reward for the Parts C and D Star 
Ratings;
    <bullet> Annual health equity analysis of utilization management 
policies and procedures;
    <bullet> Requirements for MA plans to provide culturally and 
linguistically appropriate services; and
    <bullet> Quality improvement and health risk assessments (HRAs) 
focused on equity and social determinants of health (SDOH).
    We also do not intend to finalize the following provisions from the 
proposed rule: Enhancing Health Equity Analyses: Annual Health Equity 
Analysis of Utilization Management Policies and Procedures, Part D 
Coverage of Anti-Obesity Medications (AOMs) and Application to the 
Medicaid Program, and Ensuring Equitable Access to Medicare Advantage 
Services-- Guardrails for Artificial Intelligence (AI). CMS, however, 
does want to acknowledge the broad interest in regulation of AI and 
will continue to consider the extent to which it may be appropriate to 
engage in future rulemaking in this area.

E. Conclusion

    Finally, we are clarifying and emphasizing our intent that if any 
provision of this rule is held to be invalid or unenforceable by its 
terms, or as applied to any person or circumstance, or stayed pending 
further agency action, it shall be severable from this rule and not 
affect the remainder thereof or the application of the provision to 
other persons not similarly situated or to other, dissimilar 
circumstances. Through this rule, we are finalizing provisions that are 
intended to and will operate independently of each other, even if each 
serves the same general purpose or policy goal. Where a provision is 
necessarily dependent on another, the context generally makes that 
clear (such as by a cross-reference to apply the same standards or 
requirements).

II. Implementation of IRA Provisions for the Medicare Prescription Drug 
Benefit Program

A. Coverage of Adult Vaccines Recommended by the Advisory Committee on 
Immunization Practices (ACIP) Under Medicare Part D (Sec. Sec.  423.100 
and 423.120)

1. Background
    Section 11401 of the Inflation Reduction Act of 2022 (IRA) amended 
section 1860D-2 of the Act by adding new paragraph (8) to subsection 
(b) and new paragraph (5) to subsection (c) and making other conforming 
amendments to require that, effective for plan years beginning on or 
after January 1, 2023, the Medicare Part D deductible shall not apply 
to, and there is no cost sharing for, an adult vaccine recommended by 
the Advisory Committee on Immunization Practices (ACIP) covered under 
Part D. Section 11401(e) of the IRA directed the Secretary to implement 
section 11401 of the IRA for 2023, 2024, and 2025 by program 
instruction or other forms of program guidance. In accordance with the 
law, CMS issued memoranda via the Health Plan Management System (HPMS) 
that outlined requirements for Part D sponsors regarding the 
implementation of section 11401.
    On September 26, 2022, CMS released an HPMS memorandum titled 
``Contract Year 2023 Program Guidance Related to Inflation Reduction 
Act Changes to Part D Coverage of Vaccines and Insulin.'' \1\ In this 
memorandum, we provided guidance that for any new ACIP-recommended 
adult vaccine that becomes available during a plan year, Part D 
sponsors must apply the $0 cost-sharing requirements in section 1860D-
2(b)(8) of the Act to applicable claims with dates of service after 
ACIP's issued recommendation.

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

    On April 4, 2023, CMS issued an HPMS memorandum titled ``Final 
Contract Year (CY) 2024 Part D Bidding Instructions'' which explained 
that, in order for a vaccine to be considered ACIP-recommended for 
adult use, it must be both adopted by the Director of the Centers for 
Disease Control and Prevention (CDC) and published in the CDC's 
Morbidity and Mortality Weekly Report (MMWR).\2\
---------------------------------------------------------------------------

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

    On July 24, 2023, CMS issued a revision to the April 4, 2023 
memorandum, which clarified that the effective date of the $0 cost-
sharing requirement for an ACIP-recommended

[[Page 15796]]

adult vaccine must be aligned with the date on which the CDC Director 
adopts the respective ACIP vaccine recommendation, as posted on the 
CDC's website, not the date on which the recommendation is published in 
the MMWR.\3\
---------------------------------------------------------------------------

    \3\ <a href="https://www.cms.gov/files/document/acip-recommended-vaccines-july-2023.pdf">https://www.cms.gov/files/document/acip-recommended-vaccines-july-2023.pdf</a>.
---------------------------------------------------------------------------

    In this rule, we are finalizing our proposal to codify the 
requirements related to $0 cost sharing for adult vaccines recommended 
by ACIP under Part D for 2026 and each subsequent plan year.
    We received the following comments on this section of the proposed 
rule, and our responses follow:
    Comment: Many commenters supported CMS' proposal to codify the 
statutory $0 cost-sharing requirement for ACIP-recommended adult 
vaccines that was added to section 1860D-2 of the Act by section 11401 
of the Inflation Reduction Act.
    Response: We thank the commenters for their support of our 
proposal.
2. Definition of ACIP-Recommended Adult Vaccine
    Section 1860D-2(b)(8)(B) of the Act specifies that for purposes of 
section 1860D-2(b)(8) of the Act, the term ``adult vaccine recommended 
by the Advisory Committee on Immunization Practices'' means a covered 
Part D drug that is a vaccine licensed by the U.S. Food and Drug 
Administration (FDA) under section 351 of the Public Health Service Act 
(PHSA) for use by adult populations and administered in accordance with 
recommendations of the CDC's ACIP as adopted by the CDC Director. We 
proposed to refer to these vaccines as ``ACIP-recommended adult 
vaccines'' and to codify this definition at Sec.  423.100. We did not 
propose to specify a particular age for a vaccine to be considered 
``adult'' for the purposes of determining if a Part D vaccine is 
subject to $0 cost sharing under section 11401 of the IRA. We deferred 
to how the CDC and ACIP categorize such a recommendation. Part D 
sponsors must use the information provided by the CDC and ACIP to 
determine if the vaccine is recommended for, and being administered to, 
an adult.
    Consistent with the September 26, 2022 HPMS memorandum, we proposed 
to define an ``ACIP-recommended adult vaccine'' as a vaccine licensed 
by the FDA for use in adults and administered in accordance with ACIP 
recommendations. In alignment with the September 26, 2022 HPMS 
memorandum, we interpreted the term ``recommendation'' to refer to a 
recommendation under any one of ACIP's categories of recommendations, 
including routine, catch-up, risk-based, and shared clinical decision-
making immunization recommendations.
    Some vaccines that are not on the ACIP Adult Immunization Schedule 
for routine immunization are included on the ACIP Vaccine 
Recommendations and Guidelines web page.\4\ This web page describes 
ACIP recommendations for vaccines that are used in limited populations 
and under limited circumstances. For example, ACIP recommends certain 
vaccinations for travelers prior to visiting certain countries. 
Therefore, consistent with the September 26, 2022 HPMS memorandum, as 
long as the vaccine is an FDA-licensed vaccine that is recommended by 
ACIP for use by adults, such vaccine would meet our proposed definition 
of an ACIP-recommended adult vaccine, when provided in accordance with 
ACIP recommendations.
---------------------------------------------------------------------------

    \4\ <a href="https://www.cdc.gov/acip-recs/hcp/vaccine-specific/index.html">https://www.cdc.gov/acip-recs/hcp/vaccine-specific/index.html</a>.
---------------------------------------------------------------------------

    As described in the September 26, 2022 HPMS memorandum, a Part D 
vaccine would not meet our proposed definition of an ACIP-recommended 
adult vaccine and, therefore, would not be subject to the requirements 
implemented in this final rule, if the vaccine is: (1) not licensed by 
the FDA under section 351 of the PHSA for use by adults; (2) not 
recommended by ACIP for use by adults; (3) administered to an 
individual who is not an adult, even if such use in the non-adult is 
supported by ACIP recommendations (for example, recommendations in the 
ACIP child and adolescent immunization schedule); or (4) not 
administered in accordance with ACIP recommendations.
    In summary, we proposed to add at Sec.  423.100 a definition of 
``ACIP-recommended adult vaccine'' that means a covered Part D drug, as 
defined at Sec.  423.100, that is a vaccine licensed by the FDA under 
section 351 of the Public Health Service Act for use by adult 
populations and administered in accordance with recommendations of ACIP 
of the CDC as adopted by the CDC Director.
    We received the following comments on this section of the proposed 
rule, and our responses follow:
    Comment: A few commenters requested that we release a HPMS 
memorandum that includes a list of ACIP-recommended adult vaccines and 
the dates on which these vaccines should be covered with no cost 
sharing.
    Response: The most updated information regarding ACIP-recommended 
adult vaccines and the effective date of ACIP recommendations is 
available on the Centers for Disease Control and Prevention's (CDC's) 
website at: <a href="https://www.cdc.gov/acip-recs/hcp/vaccine-specific/">https://www.cdc.gov/acip-recs/hcp/vaccine-specific/</a>. Given 
that the CDC's website is the best source for this information, we 
decline to accept the commenters' recommendation to issue separate 
guidance.
3. No Deductible or Cost Sharing for ACIP-Recommended Adult Vaccines
    Section 1860D-2(b)(8)(A) of the Act specifies that the deductible 
shall not apply and there shall be no coinsurance or other cost sharing 
with respect to ACIP-recommended adult vaccines. Generally, Part D 
vaccines that have ACIP-recommended uses in the adult population and 
are administered to an adult must be provided with no enrollee cost 
sharing. As described in the September 26, 2022 HPMS memorandum, this 
means that enrollees must not be subject to cost sharing on the 
ingredient cost of the vaccine submitted on the prescription drug event 
(PDE) record, or any associated sales tax, dispensing fee, or vaccine 
administration fee, regardless of the vaccine's formulary tier 
placement or the benefit phase that the enrollee is in.
    We also proposed at Sec.  423.120(g)(3) that enrollees who submit 
direct member reimbursement (DMR) requests for ACIP-recommended adult 
vaccines accessed at either out-of-network pharmacies or providers (in 
accordance with Sec.  423.124(a) and (c)), or at in-network pharmacies 
or providers, that a Part D sponsor determines are coverable under 
their benefit must not be subject to cost sharing. While Part D 
sponsors generally may charge the enrollee for the difference between 
the cash price and plan allowance for DMRs for covered Part D drugs 
accessed from both out-of-network and in-network pharmacies, neither 
Sec.  423.124(b) nor Chapter 14 of the Prescription Drug Benefit Manual 
directly addresses covered Part D drugs that have statutorily limited 
cost sharing.\5\

[[Page 15797]]

Because there can be no cost sharing for ACIP-recommended adult 
vaccines accessed at either out-of-network pharmacies or providers (in 
accordance with Sec.  423.124(a) and (c)), or at in-network pharmacies 
or providers, that a Part D sponsor determines are coverable under 
their benefit, the Part D sponsor must reimburse the enrollee for the 
full cash price paid to the pharmacy or provider for an ACIP-
recommended adult vaccine.
---------------------------------------------------------------------------

    \5\ Section 423.124(b) currently states that a Part D sponsor 
that provides its Part D enrollees with coverage other than defined 
standard coverage may require its Part D enrollees accessing covered 
Part D drugs at out-of-network pharmacies to assume financial 
responsibility for any differential between the out-of-network 
pharmacy's (or provider's) usual and customary price and the Part D 
sponsor's plan allowance. Section 50.4.3 of Chapter 14 of the 
Medicare Prescription Drug Benefit Manual (<a href="https://www.cms.gov/medicare/prescription-drug-coverage/prescriptiondrugcovcontra/downloads/chapter-14-coordination-of-benefits-v09-17-2018.pdf">https://www.cms.gov/medicare/prescription-drug-coverage/prescriptiondrugcovcontra/downloads/chapter-14-coordination-of-benefits-v09-17-2018.pdf</a>) 
provides detailed guidance on how Part D sponsors must process DMR 
requests that are submitted by enrollees who paid cash at an out-of-
network (or an in-network) pharmacy (or provider) and where the 
pharmacy (or provider) did not submit the claim to the Part D plan.
---------------------------------------------------------------------------

    The total gross covered drug cost (TGCDC) is usually reported 
differently on PDEs depending on whether the drug was accessed at an 
out-of-network or in-network pharmacy or provider. Specifically, Part D 
sponsors report the cash price that the enrollee paid to the pharmacy 
or provider as the TGCDC for out-of-network DMRs but only report the 
negotiated price as the TGCDC for in-network DMRs. However, we 
clarified in the proposed rule that with respect to ACIP-recommended 
adult vaccines, as an exception to the Chapter 14 guidance, the sponsor 
should report the cash price paid to the pharmacy or provider as the 
TGCDC on the PDE for both out-of-network and in-network DMRs. 
Regardless, there is no true out-of-pocket (TrOOP) cost accumulation 
for these claims because the beneficiary has no cost sharing for ACIP-
recommended adult vaccines under the basic Part D benefit.
    Under our proposed policy at Sec.  423.120(g), and as described in 
the September 26, 2022 HPMS memorandum, new Part D vaccines that become 
available during the plan year and meet the definition of an ACIP-
recommended adult vaccine are subject to the cost-sharing requirements 
of section 1860D-2(b)(8)(A) of the Act. Consistent with the definition 
of a covered Part D drug at Sec.  423.100, the statutory cost-sharing 
requirements apply regardless of whether a Part D sponsor adds the 
vaccine to the formulary midyear, or the enrollee obtains the vaccine 
via a formulary exception. In addition, we proposed at Sec.  
423.120(g)(2) that if ACIP issues a new or revised recommendation for a 
vaccine, related to its use in adults during the plan year, Part D 
sponsors must apply the cost-sharing requirements of this final rule, 
as applicable, to any ACIP-recommended adult vaccine claims with dates 
of service after the proposed ``effective date of the ACIP 
recommendation.''
    Consistent with the April 4, 2023 HPMS memorandum, Part D sponsors 
may place ACIP-recommended adult vaccines on any tier, including a 
vaccine tier, and apply utilization management strategies (for example, 
prior authorization), insofar as such tier placement or utilization 
management strategy is consistent with the requirements of CMS's 
formulary review and approval process under Sec.  423.120(b).
    As described in Section 30.2.7 of Chapter 6 of the Prescription 
Drug Benefit Manual, Part D sponsors may only use utilization 
management strategies to assess the necessity of vaccines that are less 
commonly administered in the Medicare population, facilitate the use of 
vaccines in line with ACIP recommendations, and evaluate potential 
reimbursement of vaccines that could be covered under Part B.\6\ For 
example, utilization management strategies may be used to ensure an 
enrollee meets the age or clinical requirements recommended by ACIP for 
a particular vaccine, such as the respiratory syncytial virus (RSV) 
vaccine which is currently recommended by ACIP for adults aged 75 years 
of age and older and adults aged 60 to 74 years of age who are at 
increased risk for severe RSV disease. However, regardless of an ACIP-
recommended adult vaccine's tier placement or applicable utilization 
management strategies, the statutory zero cost-sharing limits required 
under this final rule would still apply.
---------------------------------------------------------------------------

    \6\ <a href="https://www.cms.gov/medicare/prescription-drug-coverage/prescriptiondrugcovcontra/downloads/part-d-benefits-manual-chapter-6.pdf">https://www.cms.gov/medicare/prescription-drug-coverage/prescriptiondrugcovcontra/downloads/part-d-benefits-manual-chapter-6.pdf</a>.
---------------------------------------------------------------------------

    In summary, we proposed to codify at Sec.  423.120(g)(1) the 
requirement that Part D sponsors must not apply the deductible or 
charge cost sharing on ACIP-recommended adult vaccines. We also 
proposed to codify at Sec.  423.120(g)(2) that once a new or revised 
recommendation is posted on the CDC website, Part D sponsors must 
provide coverage consistent with Sec.  423.120(g)(1) for dates of 
service on or after the ``effective date of the ACIP recommendation.'' 
Finally, we proposed to codify at Sec.  423.120(g)(3) that these cost-
sharing requirements apply for ACIP-recommended adult vaccines obtained 
from either in-network or out-of-network pharmacies or providers (in 
accordance with Sec.  423.124(a) and (c)).
    We received the following comments on this section of the proposed 
rule, and our responses follow:
    Comment: Several commenters provided feedback related to the 
implementation of utilization management strategies for vaccines. A few 
of these commenters opposed the use of utilization management 
strategies to determine whether an enrollee meets the age or clinical 
requirements recommended by ACIP for a particular vaccine. These 
commenters stated that utilization management can limit or delay 
beneficiaries' access to vaccines. A commenter urged CMS to ensure that 
all commercially available Part D vaccines are included on Part D 
formularies and that utilization management for vaccines is used 
appropriately. Another commenter urged CMS to issue guidance to ensure 
Part D plans are providing coverage and access to ACIP-recommended 
vaccines and are not imposing restrictive utilization management 
strategies. Finally, other commenters requested that CMS ensure Part D 
sponsors are not implementing utilization management strategies that 
prevent a provider or pharmacy from stocking or administering vaccines.
    Response: We appreciate these commenters sharing their concerns 
related to utilization management strategies for vaccines. As described 
in Chapter 6, Section 30.2.7 of the Prescription Drug Benefit Manual, 
CMS reviews all Part D sponsors' formularies to ensure they contain all 
commercially available Part D vaccines and to ensure that Part D 
sponsors are only using utilization management tools to--
    <bullet> Assess the necessity of vaccines that are less commonly 
administered in the Medicare population, such as anthrax and yellow 
fever vaccines;
    <bullet> Facilitate use of vaccines in line with ACIP 
recommendations; and
    <bullet> Evaluate potential reimbursement of those vaccines that 
could be covered under Part B when directly related to the treatment of 
an injury or direct exposure to a disease or condition (for example, 
tetanus).
    In order to ensure a vaccine meets the definition of an ``ACIP-
recommended adult vaccine'' and is therefore subject to the cost-
sharing requirements outlined in this rule, a Part D sponsor may 
implement utilization management strategies to determine if the vaccine 
is being administered in accordance with ACIP recommendations, which is 
consistent with the Chapter 6 guidance outlined previously.
    Given that our existing guidance in Chapter 6 of the Prescription 
Drug Benefit Manual clearly outlines the situations in which Part D 
sponsors may implement utilization management for vaccines, we decline 
to issue additional guidance on this topic.
    Comment: Several commenters expressed concern about Part D sponsors 
restricting coverage for specific vaccine products and having a 
``preferred'' brand of a particular

[[Page 15798]]

vaccine. Commenters stated that these restrictions have been 
implemented using utilization management strategies (for example, step 
therapy), $0 reimbursement to pharmacies for less preferred vaccine 
products, and National Drug Code (NDC) blocks. Commenters emphasized 
the negative impact these strategies may have on beneficiary access to 
vaccines. For example, the commenters asserted that a beneficiary may 
present to a pharmacy to receive a vaccine and, if the vaccine product 
in stock is not the ``preferred'' brand on the beneficiary's Part D 
plan's formulary, the beneficiary would need to return to the pharmacy 
once the ``preferred'' brand is in stock or find another pharmacy with 
the ``preferred'' brand currently in stock. Commenters also stated how 
difficult and costly it would be to keep every brand of a vaccine in 
stock to avoid these situations. A commenter noted that this would be 
particularly costly in primary care settings where providers are not 
paid until after a vaccine is administered, and they cannot receive 
reimbursement for unused vaccines. All commenters requested that CMS 
not allow these strategies to be implemented.
    Response: We appreciate the concerns these commenters shared about 
the potential negative impacts of Part D sponsors restricting coverage 
for certain brands of a vaccine. We reiterate our rules outlined in 
Chapter 6, Section 30.2.7, of the Prescription Drug Benefit Manual 
which state that Part D sponsors' formularies must contain all 
commercially available Part D vaccines and, as discussed earlier in 
this preamble, the only allowable uses of utilization management for 
vaccines are to assess the necessity of vaccines that are less commonly 
administered in the Medicare population, facilitate the use of vaccines 
in line with ACIP recommendations, and evaluate potential reimbursement 
of vaccines that could be covered under Part B. Given that these are 
the only situations in which utilization management can be used for 
vaccines, Part D sponsors may not implement utilization management, 
including step therapy and NDC blocks, to prefer one brand of a vaccine 
over another.
    Comment: A few commenters expressed concerns about beneficiaries 
receiving Part D vaccines in primary care settings. The commenters 
stated that because these settings are not considered in-network, 
beneficiaries must pay for the vaccine and wait to be reimbursed, which 
can disincentivize them from receiving recommended vaccines. The 
commenters emphasized that being considered out-of-network can 
negatively affect primary care providers' relationships with their 
patients as they navigate vaccine coverage requirements for each 
patient and must often refer patients to network pharmacies to receive 
recommended vaccines. A commenter stated that having to refer patients 
to network pharmacies for vaccine administration can lead to confusion 
and increased vaccine hesitancy and may disproportionately affect 
patients who may have difficulty obtaining transportation to an in-
network pharmacy. They also noted that individuals without Part D 
coverage are not able to receive ACIP-recommended adult vaccines with 
no cost sharing.
    Another commenter requested that we describe our expectations for 
applying utilization management strategies when vaccines are 
administered at an out-of-network pharmacy, such as a primary care 
setting, as Part D sponsors do not have direct relationships with 
providers in these settings. The commenter stated that there can be 
operational barriers to imposing utilization management in these 
settings and requested guidance on how to implement utilization 
management when vaccines are administered by providers, such as 
physicians, in out-of-network settings.
    Response: We appreciate the commenters sharing their concerns about 
Part D enrollees receiving ACIP-recommended vaccines out-of-network. 
Part D sponsor networks are generally defined as pharmacy networks; 
therefore, if an enrollee receives a vaccine at a physician's office, 
this is most often out-of-network. As noted in the preamble to the 
final rule titled ``Medicare Program; Medicare Prescription Drug 
Benefit'' which appeared in the Federal Register on January 28, 2005 
(70 FR 4194), a Part D enrollee receiving a vaccine in a physician's 
office constitutes a situation in which out-of-network access would be 
permitted because a beneficiary could not reasonably be expected to 
obtain that vaccine at a network pharmacy. We refer the commenters to 
our current regulations and guidance regarding claims for vaccines 
administered out-of-network. Specifically, Sec.  423.124(a)(2) 
establishes that Part D sponsors must ensure that Part D enrollees have 
adequate access to vaccines and other covered Part D drugs 
appropriately dispensed and administered by a physician in a 
physician's office. In Chapter 5, Section 60.2, of the Prescription 
Drug Benefit Manual, we note that it may be challenging for enrollees 
to pay upfront and be reimbursed by their Part D plan after receiving a 
vaccine in their physician's office.
    We encourage the commenters to review the possible approaches 
detailed in Section 60.2.2 of the Prescription Drug Benefit Manual to 
improve access to Part D vaccines administered and dispensed by a 
physician without requiring upfront beneficiary payment and subsequent 
reimbursement by Part D sponsors. The two possible approaches are: (1) 
a model vaccine notice for physicians (paper claim enhancement) where 
Part D sponsors provide all enrollees with a vaccine-specific notice 
that enrollees can bring to their physician with the information 
necessary for a physician to receive authorization of coverage for a 
particular vaccine and bill for the vaccine; and (2) web-assisted 
electronic physician billing where a physician uses a commercially-
developed web-based system to electronically request out-of-network 
reimbursement from Part D sponsors on behalf of enrollees. Both 
approaches allow providers in primary care settings to administer ACIP-
recommended vaccines to Part D enrollees without requiring an upfront 
payment.
    Regarding utilization management for vaccines administered in out-
of-network settings, we would expect that any utilization management 
requirements imposed on vaccines would need to be satisfied regardless 
of whether the vaccine is being administered at a network or out-of-
network setting. However, we believe Part D sponsors are best situated 
to determine how to operationalize the implementation of utilization 
management requirements for out-of-network claims. As discussed earlier 
in this preamble, the only allowable uses of utilization management for 
vaccines are to assess the necessity of vaccines that are less commonly 
administered in the Medicare population, facilitate the use of vaccines 
in line with ACIP recommendations, and evaluate potential reimbursement 
of vaccines that could be covered under Part B. We also note that, 
consistent with Chapter 6, Section 10.14.3, of the Prescription Drug 
Benefit Manual, in the absence of any information showing previous 
immunization (that is, claims data), the Part D sponsor should make 
payment available for a vaccine and its administration consistent with 
ACIP recommendations. Therefore, if a Part D sponsor determines an 
ACIP-recommended adult vaccine is coverable under their benefit, the 
enrollee must not be subject to cost sharing regardless of whether they 
received the vaccine in-network or out-

[[Page 15799]]

of-network. Alternatively, if a Part D sponsor determines a vaccine 
does not meet the definition of an ``ACIP-recommended adult vaccine,'' 
the $0 cost-sharing requirement would not apply.
    Comment: A commenter requested clarification on managing coverage 
determinations in instances where a Part D sponsor requires a prior 
authorization (PA) for a vaccine. The commenter stated that because 
many vaccines are administered in pharmacies under standing orders, 
there is not a physician writing an individual prescription for each 
enrollee receiving a vaccine. Therefore, there is no physician who can 
provide information in support of a PA or appeal. The commenter noted 
that pharmacies are typically not involved in coverage determinations 
and questioned whether a pharmacist is permitted to request a PA or 
appeal and provide information in support of a PA or appeal.
    Response: As described in Sec.  423.566(c), the only individuals 
who can request a standard or expedited coverage determination are the 
enrollee; the enrollee's representative, on behalf of the enrollee; or 
the prescribing physician or other prescriber, on behalf of the 
enrollee. However, as stated in Section 40.12.3 of the Parts C & D 
Enrollee Grievances, Organization/Coverage Determinations, and Appeals 
Guidance, Part D sponsors are permitted, but not required, to treat the 
presentation of a prescription at the pharmacy as a coverage 
determination. Therefore, a Part D sponsor can treat a transaction in 
which a pharmacist explains to an enrollee that a drug is subject to 
prior authorization as a request for a coverage determination. A 
pharmacist may then communicate with the Part D sponsor and may be able 
to override the point-of-sale prior authorization requirement and allow 
the claim to process. As stated in Chapter 6, Section 30.2.2.1, of the 
Prescription Drug Benefit Manual, Part D sponsors may decide that it is 
reasonable to accept information from pharmacists in situations where 
point-of-sale edits are applied. In these cases, if a network pharmacy 
is able to provide the necessary information at the point-of-sale, it 
negates the need for additional administrative review through the 
coverage determination process and reduces delay in access to Part D 
drugs, including vaccines. However, we note that a pharmacist's 
involvement would occur at the initial coverage decision level, 
consistent with Section 40.9 of the Parts C & D Enrollee Grievances, 
Organization/Coverage Determinations, and Appeals Guidance, and not the 
appeal level.
    Comment: A commenter requested guidance on how to manage situations 
in which PA requests are submitted for vaccines. The commenter 
described a situation in which the Part D sponsor determines that a 
vaccine is not being administered in accordance with ACIP's 
recommendations and the enrollee is charged the applicable cost 
sharing. The commenter questioned whether this would be considered a 
fully favorable, partially unfavorable, or fully unfavorable decision. 
If this is a partially or fully unfavorable decision, the commenter 
questioned whether this decision should be classified as a denial due 
to a lack of medical necessity. The commenter also requested guidance 
for how plans should process requests in situations where a request is 
submitted to the plan for a vaccine to be covered at $0 cost sharing, 
but the plan determines the vaccine is not being administered in 
accordance with ACIP recommendations. The commenter noted that CMS did 
not propose allowing enrollees to request cost-sharing exceptions when 
a vaccine is not being administered in accordance with ACIP 
recommendations. Specifically, the commenter questioned whether these 
requests should be dismissed or denied.
    Response: If a request is submitted to a Part D plan asking for a 
vaccine to be covered at $0 cost sharing, we would expect either: (1) a 
fully favorable decision if the vaccine is covered at $0; (2) a 
partially favorable decision if the vaccine is covered but subject to 
cost sharing; or (3) an adverse decision if the vaccine is not covered. 
If a request is submitted to a Part D plan asking for a vaccine to be 
covered, but the request does not specify a preferred cost-sharing 
amount, we would expect either: (1) a fully favorable decision if the 
vaccine is covered but subject to cost sharing; or (2) an adverse 
decision if the vaccine is not covered. In cases where a partially 
favorable or adverse decision is made, an enrollee must be provided 
proper notice and appeal rights, consistent with Sec.  423.568(g). We 
note that it would not be appropriate to dismiss a request in any of 
these scenarios. A partially favorable or adverse decision would be 
considered a denial.
    Comment: A commenter encouraged CMS to educate pharmacists about 
direct member reimbursement (DMR) requests so they can inform their 
patients that reimbursement is available for vaccines received out-of-
network.
    Response: We thank the commenter for their suggestion. Part D plans 
currently provide information to their enrollees regarding how to 
request reimbursement when they use an out-of-network pharmacy or 
provider in Chapter 5 of the Evidence of Coverage (EOC) document which 
is provided to all Part D enrollees.
    Comment: A commenter questioned whether direct member reimbursement 
(DMR) requests for ACIP-recommended adult vaccines can only be 
submitted by beneficiaries or also by providers, including physicians 
and pharmacies. The commenter noted that they have seen provider-
submitted claims that charge more than the negotiated rates for 
vaccines. If requests cannot be submitted by providers, the commenter 
recommended that CMS issue separate guidance for provider-submitted 
claims to ensure there is clarity on how these requests should be 
managed. They also recommend that CMS limit reimbursement for these 
claims to contracted rates. If requests can be submitted by providers, 
the commenter recommended that CMS monitor claims for ACIP-recommended 
vaccines as the $0 cost-sharing requirement for these vaccines may 
increase both the plan and CMS' liability. The commenter also stated 
that because there is no limit on the price of ACIP-recommended 
vaccines, it is possible that pharmacies and providers may charge 
higher cost sharing at the point-of-sale and, instead of processing 
claims online, they would have the beneficiary submit the claim to 
their Part D plan in order to receive a higher payment. Another 
commenter questioned how, when DMR requests are submitted, 
reimbursement to providers for the vaccine product and administration 
fees should be addressed. The commenter noted that vaccinating 
providers continue to face challenges with receiving adequate 
reimbursement for providing vaccines.
    Response: We thank the commenter for sharing their questions and 
recommendations regarding DMR requests. We note that our reference to 
DMR requests in the proposed and final rules is specific to 
beneficiary-submitted requests where a beneficiary is requesting 
reimbursement for an ACIP-recommended adult vaccine for which they 
incurred out-of-pocket costs. With respect to DMR requests submitted by 
beneficiaries for prescriptions obtained from in-network pharmacies, 
Sec.  423.120(c)(3) specifies that a Part D sponsor must require its 
network pharmacies to submit claims to the Part D sponsor or its 
intermediary whenever the card described in paragraph (c)(1) of this 
section is presented or on file at the pharmacy unless the enrollee 
expressly requests that a particular claim not be submitted to the Part 
D sponsor or its

[[Page 15800]]

intermediary. Network pharmacies that decline to process network claims 
online and instead recommend that beneficiaries submit paper claims 
would be in violation of this requirement. We continue to expect DMR 
requests for prescriptions obtained from network pharmacies to be 
limited and submitted only for reasons, such as the claims processing 
systems being temporarily unavailable for the pharmacy or the Part D 
sponsor or its intermediary when the enrollee obtains their 
prescription. Any post-reimbursement reconciliation between the network 
pharmacy and plan sponsor would be a contractual matter between the 
parties.
    With respect to provider-submitted claims for vaccines, which we do 
not consider DMR requests, CMS does not prohibit Part D sponsors from 
establishing arrangements with out-of-network (OON) providers or 
pharmacies to facilitate OON access in accordance with the requirements 
specified in Sec.  423.124. As described earlier in this preamble, 
Chapter 5, Section 60.2, of the Prescription Drug Benefit Manual 
provides options that Part D sponsors and OON providers may use to 
facilitate access to vaccines given that vaccines are often provided in 
physician offices. While we encourage such arrangements for vaccine 
access, CMS guidance makes it clear that it is not a requirement and 
that such facilitated approaches to OON access for vaccines would need 
to be agreed upon between the Part D sponsor and provider. Therefore, 
it is up to Part D sponsors to establish their own policies on whether 
to accept OON claims directly from providers or pharmacies, and, if 
they do, to establish an agreed upon reimbursement amount with the OON 
provider or pharmacy that could include a prohibition on balance 
billing the enrollee.
    Our guidance for provider-submitted claims for vaccines is provided 
in Chapter 5 of the Prescription Drug Benefit Manual, as discussed 
previously.
4. Effective Date of ACIP Recommendations
    In the July 24, 2023 HPMS memorandum, we stated that Part D 
sponsors must provide $0 cost sharing for an ACIP-recommended adult 
vaccine as of the date the CDC Director adopts the ACIP's 
recommendation and it is posted on the CDC's website. Accordingly, we 
proposed to add at Sec.  423.100 a definition of ``effective date of 
the ACIP recommendation'' that means the date specified on the CDC 
website noting the date the CDC Director adopted the ACIP 
recommendation.
    In the proposed rule, we noted that it is highly unlikely that an 
ACIP recommendation will be posted without the date on which it was 
adopted by the CDC Director; however, in the event that a 
recommendation is posted without an effective date, we noted that CMS 
would consult with the CDC to obtain the date the recommendation was 
adopted by the CDC Director and provide guidance.
    In the proposed rule, we noted that the ``effective date of the 
ACIP recommendation'' and the date on which it is published on the 
CDC's website may not always be the same date (if, for example, the 
website posting occurs after the date specified as the date the CDC 
Director adopted the recommendation). Nevertheless, we proposed that 
the ``effective date of the ACIP recommendation'' would determine when 
the cost-sharing requirements apply. Consequently, if an enrollee paid 
cost sharing for an ACIP-recommended adult vaccine after the 
``effective date of the ACIP recommendation'' (for example, the 
enrollee received the vaccine after the ``effective date of the ACIP 
recommendation,'' but prior to the recommendation being posted on the 
CDC website), once the recommendation has been posted to the CDC 
website, the Part D sponsor would need to reimburse the enrollee for 
any cost sharing they paid for the vaccine.
    In instances where ACIP expands a previous recommendation, narrows 
a previous recommendation, or removes a previous recommendation, the 
proposed ``effective date of the ACIP recommendation'' would be the 
date the CDC Director adopted the changed recommendation once the 
recommendation is posted on the CDC's website. We noted in the proposed 
rule that a change to an ACIP recommendation alone does not affect a 
vaccine's status as a Part D drug. Specifically, a Part D drug is 
defined at Sec.  423.100, in relevant part, as including a vaccine, if 
used for a medically accepted indication, as defined in section 1860D-
2(e)(4) of the Act. Since an ACIP recommendation does not affect what 
is considered a medically accepted indication, as defined under section 
1860D-2(e)(4) of the Act, for a particular vaccine, an ACIP 
recommendation alone does not affect a vaccine's status as a Part D 
drug. However, if the FDA labeling changes to align with a narrowed 
ACIP recommendation, this may change what is considered a medically 
accepted indication and may change what indications are coverable under 
Part D for a particular vaccine. In other words, if an ACIP 
recommendation is narrowed or removed, the vaccine may still be 
coverable under Part D, but an enrollee may be subject to cost sharing 
for the vaccine if it is not administered in accordance with the 
revised ACIP recommendation.
    In the proposed rule, we also noted that when an ACIP 
recommendation for a particular vaccine is narrowed (for example, 
additional restrictions are added or the vaccine is recommended for a 
more limited patient population), Part D sponsors may implement PA to 
determine whether the vaccine is being administered in accordance with 
ACIP recommendations and whether the enrollee should be subject to cost 
sharing. For example, if an ACIP recommendation is amended to raise the 
age for which a vaccine is recommended to be administered, Part D 
sponsors may implement PA to ensure a beneficiary meets this new age 
requirement. However, Part D sponsors are not required to implement PA 
for vaccines to determine if a vaccine is being used for an ACIP-
recommended use and is therefore subject to $0 cost sharing.
    Additionally, we discussed in the proposed rule that when an ACIP 
recommendation is narrowed and a Part D sponsor does not currently have 
a PA requirement in place for that vaccine, the plan may submit a 
negative formulary change request to add a PA requirement for that 
vaccine that aligns with the newly narrowed recommendation, consistent 
with Sec.  423.120(e)(1). Once the request is approved, Part D sponsors 
may implement the PA requirement and, if the plan determines that the 
vaccine is not being used for an ACIP-recommended use, may charge the 
enrollee the applicable cost sharing. Part D sponsors are permitted, 
but not required, to make retroactive determinations for claims that 
were processed with $0 cost sharing after the ``effective date of the 
ACIP recommendation'' and before the date on which the PA requirement 
went into effect.
    If ACIP withdraws a recommendation for a previously recommended 
vaccine such that the vaccine no longer meets the definition of an 
ACIP-recommended adult vaccine, Part D sponsors are not required to 
submit a negative change request and may immediately apply cost sharing 
for the vaccine for dates of service after the ``effective date of the 
ACIP recommendation.''
    Because the cost-sharing limits for vaccines outlined in our 
proposed rule, and finalized in this final rule, have been in place 
since 2023 through program instruction authority and we have annually 
reviewed cost sharing in

[[Page 15801]]

plan benefit package submissions, we believe the impacts of our 
proposed codification of these requirements should have minimal impact 
on Part D sponsors and beneficiaries.
    We received the following comments on this section of the proposed 
rule, and our responses follow.
    Comment: A few commenters requested that we change the definition 
of the ``effective date of the ACIP recommendation.'' A commenter 
recommended we use the date the recommendation is published in the 
CDC's MMWR. Another commenter recommended we use the day after the last 
day of the ACIP meeting at which the recommendation was approved. 
Another commenter expressed concern about situations in which the CDC 
Director does not adopt an ACIP recommendation.
    Response: We thank the commenters for their suggestions, but we 
decline to change our definition of the ``effective date of the ACIP 
recommendation.'' As we explained in the proposed rule, in the April 4, 
2023 HPMS memorandum titled ``Final Contract Year (CY) 2024 Part D 
Bidding Instructions,'' we stated that the effective date for an ACIP 
recommendation is the date on which it is adopted by the CDC Director 
and published in the MMWR. However, on July 24, 2023, based on updated 
instruction from the CDC, we issued a revision to the memorandum and 
clarified that the effective date is the date on which the CDC Director 
adopts the ACIP recommendation, as posted on the CDC's website, not the 
date on which the recommendation is published in the MMWR. We noted 
that if the date of publication in the MMWR was used, it is likely 
there would be a delay in beneficiaries accessing new ACIP-recommended 
vaccines at $0 cost sharing because of the delay in publication. For 
example, on October 24, 2024, the CDC Director adopted recommendations 
to update the dosing interval and schedule for a meningococcal 
serogroup B vaccine (MenB-4C), but the recommendation was not published 
in the MMWR until December 12, 2024.<SUP>7 8</SUP>

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

    In the July 24, 2023 memorandum, we also stated that if the CDC 
Director's adoption of an ACIP recommendation is posted as official on 
the CDC website but an adoption date is not specified, the effective 
date would be the day after the last day of the ACIP meeting at which 
the recommendation was approved. However, we did not include this 
requirement in the proposed rule. We understand from the CDC that there 
may be situations in which the CDC Director amends or rejects a 
recommendation after the ACIP meeting concludes. Therefore, if the day 
after the last day of the ACIP meeting date was used as the ``effective 
date of the ACIP recommendation,'' it is possible that a vaccine could 
be inappropriately considered an ACIP-recommended adult vaccine for a 
short period of time.
    Our proposed definition of ``effective date of the ACIP 
recommendation'' aligns with the CDC's current process for publishing 
ACIP recommendations that have been adopted by the CDC Director. Based 
on guidance from the CDC, it is highly unlikely that an ACIP 
recommendation will be posted without the date on which it was adopted 
by the CDC Director. In the unlikely event this does occur, CMS will 
consult with the CDC to obtain the date the recommendation was adopted 
by the CDC Director and provide guidance.
    Comment: A commenter questioned CMS's expectations when an existing 
ACIP recommendation is narrowed. The commenter requested clarification 
regarding whether Part D sponsors are required to add a PA requirement 
with respect to the vaccine and to submit a negative formulary change 
request to CMS when an ACIP recommendation is narrowed. The commenter 
stated that if CMS requires plans to submit a negative formulary change 
request to add a PA requirement in response to a narrowed ACIP 
recommendation, this would result in delays in implementing the 
narrowed ACIP recommendation. Finally, the commenter recommended that 
if a plan does add a PA requirement for a vaccine, CMS should allow the 
plan to implement the PA requirement immediately without submitting and 
waiting for approval of a negative formulary change request.
    Response: As stated in the proposed rule, Part D sponsors are not 
required to implement PA requirements for vaccines to determine if they 
are being used in accordance with ACIP recommendations. We clarify that 
Part D sponsors are not required to add a PA requirement when an ACIP 
recommendation is narrowed. However, if a Part D sponsor chooses to add 
a PA requirement to determine if the vaccine is being used in 
accordance with the narrowed ACIP recommendation, the sponsor must 
comply with the applicable negative formulary change requirements at 
Sec.  423.120(e) and applicable notice requirements at Sec.  
423.120(f).
    In the proposed rule, we stated that unless the Part D sponsor is 
otherwise notified, the negative change request will be considered 
approved after 30 days, as specified in Sec.  423.120(e)(3)(i). 
However, we clarify that, depending on the nature of the narrowed ACIP 
recommendation, the negative formulary change could be considered 
either a maintenance change or a non-maintenance change as defined at 
Sec.  423.100. If the change is a maintenance change, the requirements 
in Sec.  423.120(e)(3)(i) will apply, meaning that the request is 
deemed approved 30 days after submission unless CMS notifies the Part D 
sponsor otherwise. If the change is a non-maintenance change, the 
requirements in Sec.  423.120(e)(3)(ii) will apply, meaning that the 
change must not be implemented until the Part D sponsor receives a 
notice of approval from CMS.
    Regardless of whether a negative formulary change is considered a 
maintenance or non-maintenance change, Part D sponsors are not 
permitted to immediately implement the PA requirement and must wait 
until the negative formulary change request is approved. Once the PA 
requirement is approved, the Part D sponsor may implement the PA 
requirement and may make retroactive determinations for claims that 
were processed with $0 cost sharing after the ``effective date of the 
ACIP recommendation'' and before the date on which the PA requirement 
went into effect.
    Comment: A commenter expressed concern about potential delays in 
implementing $0 cost sharing when a new ACIP recommendation is posted 
to the CDC website by the CDC without an effective date. The commenter 
was concerned about waiting for CMS to work with CDC to obtain the 
effective date and issue guidance in instances where the CDC did not 
specify the date on which the recommendation was adopted by the CDC 
Director. The commenter requested that CMS allow a grace period for 
Part D sponsors to implement all cost-sharing changes after an ACIP 
recommendation is posted online, regardless of whether a date is 
specified or not, as it takes some time to implement cost-sharing 
changes.
    Response: We appreciate the commenter's suggestion but note that, 
based on guidance from the CDC, we expect that it is highly unlikely 
that an ACIP recommendation will be posted without the date on which it 
was adopted by the CDC Director. We also decline to make a change to 
our proposed requirements to allow Part D sponsors to have a grace 
period to implement cost-sharing changes after an

[[Page 15802]]

ACIP recommendation is posted. To ensure beneficiaries can immediately 
benefit from a new ACIP recommendation, the ``effective date of the 
ACIP recommendation'' is the date on which cost-sharing requirements 
apply. If a Part D sponsor is not able to effectuate $0 cost sharing 
for an ACIP recommended adult vaccine as of the ``effective date of the 
ACIP recommendation'' and an enrollee pays cost sharing for the ACIP-
recommended adult vaccine after the ``effective date of the ACIP 
recommendation,'' the Part D sponsor will need to reimburse the 
beneficiary for any cost sharing paid for the vaccine.
    After considering the public comments we received, and for the 
reasons set forth in the proposed rule and in our responses to 
comments, we are finalizing the changes to Sec. Sec.  423.100 and 
423.120 as proposed.

B. Cost Sharing for Covered Insulin Products Under Medicare Part D 
(Sec. Sec.  423.100 and 423.120)

1. Background
    Section 11406 of the Inflation Reduction Act of 2022 (IRA) amended 
section 1860D-2 of the Act by adding new paragraph (9) to subsection 
(b) and new paragraph (6) to subsection (c) and making other conforming 
amendments to require that, effective for plan years beginning on or 
after January 1, 2023, the Medicare Part D deductible shall not apply 
to covered insulin products, and the Part D cost-sharing amount for a 
1-month supply of each covered insulin product must not exceed the 
statutorily defined ``applicable copayment amount'' for all enrollees. 
For 2023, 2024, and 2025, the applicable copayment amount is $35. For 
2026 and each subsequent year, the applicable copayment amount is the 
lesser of: (1) $35; (2) an amount equal to 25 percent of the maximum 
fair price (MFP) established for the covered insulin product in 
accordance with Part E of title XI of the Act; or (3) an amount equal 
to 25 percent of the negotiated price of the covered insulin product 
under the PDP or MA-PD plan. Section 11406(d) of the IRA directed the 
Secretary to implement section 11406 of the IRA for 2023, 2024, and 
2025 by program instruction or other forms of program guidance. In 
accordance with the law, CMS issued several memoranda related to cost 
sharing for covered insulin products via the Health Plan Management 
System (HPMS) that outlined expectations for Part D sponsors regarding 
the implementation of section 11406. On September 26, 2022, CMS 
released an HPMS memorandum titled ``Contract Year 2023 Program 
Guidance Related to Inflation Reduction Act Changes to Part D Coverage 
of Vaccines and Insulin,'' in which we provided program instructions 
for the implementation of the requirements in section 11406.\9\ On 
April 4, 2023, we released additional guidance in the ``Final Contract 
Year (CY) 2024 Part D Bidding Instructions'' in which we provided 
instructions for Part D sponsors as they prepared to submit bids for CY 
2024.\10\ Lastly, on April 1, 2024, we released ``Final CY 2025 Part D

    We proposed to codify the cost-sharing requirements for covered 
insulin products under Part D for 2026 and each subsequent plan year.
    We received the following comments on this section of the proposed 
rule, and our responses follow:
    Comment: We received many comments that were supportive of our 
proposal to codify the statutory cost-sharing requirements for covered 
insulin products that were added to section 1860D-2 of the Act by 
section 11406 of the IRA.
    Response: We thank the commenters for their support of our 
proposal.
    Comment: A commenter requested that CMS publish technical 
prescription drug event (PDE) reporting guidance for covered insulin 
product claims.
    Response: We thank the commenter for their recommendation. We have 
released PDE reporting instructions for the implementation of 
provisions of the IRA for contract years 2023, 2024, and 2025. Our most 
recent guidance, entitled ``Prescription Drug Event Record Reporting 
Instructions for the Implementation of the Inflation Reduction Act for 
Contract Year 2025'' was published on April 15, 2024 and can be found 
here: <a href="https://www.cms.gov/files/document/pderecordreportinginstructionsfortheimplementationoftheiraforcontractyear2025508g.pdf">https://www.cms.gov/files/document/pderecordreportinginstructionsfortheimplementationoftheiraforcontractyear2025508g.pdf</a>. We anticipate that additional guidance will be released 
for contract year 2026.
2. Definition of Covered Insulin Product
    Section 1860D-2(b)(9)(C) of the Act defines a covered insulin 
product as ``an insulin product that is a covered Part D drug covered 
under a PDP or MA-PD plan and that is approved under section 505 of the 
Federal Food, Drug, and Cosmetic Act (FFDCA) or licensed under section 
351 of the Public Health Service Act (PHSA) and marketed pursuant to 
such approval or licensure, including any covered insulin product that 
has been deemed to be licensed under section 351 of the PHSA pursuant 
to section 7002(e)(4) of the Biologics Price Competition and Innovation 
Act of 2009 and marketed pursuant to such section.''
    We proposed to codify the statutory definition of ``covered insulin 
product'' at Sec.  423.100 and, in alignment with the guidance in CMS's 
September 26, 2022 HPMS memorandum, we clarified that a covered insulin 
product includes products that are a combination of more than one type 
of insulin. We also proposed, consistent with the September 26, 2022 
HPMS memorandum, that the definition of a covered insulin product 
include products that are a combination of both insulin and a non-
insulin drug or biological product. Our proposed definition of covered 
insulin product would not, however, include medical supplies associated 
with the injection of an insulin product, unless such medical supplies 
are a device constituent part of a combination product (as defined in 
21 CFR 3.2(e)) containing insulin and such combination product is 
licensed under section 351 of the PHSA.
    While our proposed definition of ``covered insulin product'' 
includes products that are a combination of more than one type of 
insulin or both insulin and non-insulin drug or biological products, 
the definition would be limited to those products that are FDA-licensed 
biological products. Consequently, because a compounded drug product, 
as described in Sec.  423.120(d), is not FDA-licensed, it would not 
meet the definition of ``covered insulin product.'' As such, a 
compounded drug product would not be subject to the requirements for a 
``covered insulin product'' under our proposed definition at Sec.  
423.100.
    Section 1860D-2(b)(9)(C) of the Act specifies that a ``covered 
insulin product'' is an insulin product that is a covered Part D drug 
covered under a PDP or MA-PD plan. Section 423.100 defines a covered 
Part D drug to be a Part D drug that is included on a Part D sponsor's 
formulary, treated as being included in a Part D plan's formulary as a 
result of a coverage determination or appeal, and obtained at a network 
pharmacy or an out-of-network pharmacy in accordance with Sec.  
423.124(a) and (c). Accordingly, we specified in our proposed 
definition at Sec.  423.100 that a ``covered insulin product'' is a 
covered Part D drug as defined in Sec.  423.100.

[[Page 15803]]

    Additionally, we proposed at Sec.  423.100 that a ``covered insulin 
product'' is licensed under section 351 of the PHSA and marketed 
pursuant to such licensure. We clarified that this proposed definition, 
in accordance with the statute, includes any covered insulin product 
that had an approved marketing application that was deemed to be a 
license for the insulin product (that is, an approved biologics license 
application) under section 351 of the PHSA pursuant to section 
7002(e)(4) of the Biologics Price Competition and Innovation Act of 
2009 and marketed pursuant to such license. We also noted that outside 
of these situations where the insulin had an approved marketing 
application under section 505 of the FFDCA, that was deemed to be a 
license for the insulin product (that is, an approved biologics license 
application) under section 351 of the PHSA pursuant to section 
7002(e)(4) of the Biologics Price Competition and Innovation Act of 
2009, there is no need to reference section 505 of the FFDCA since a 
biological product can no longer be approved under section 505 of the 
FFDCA and must be licensed in a biologics license application under 
section 351 of the PHSA. As such, a reference to section 505 is not 
included in our proposed definition of a ``covered insulin product.''
    We did not receive any comments on this section of the proposed 
rule and are finalizing the definition of ``covered insulin product'' 
at Sec.  423.100 as proposed.
3. Definition of Applicable Cost-Sharing Amount for Covered Insulin 
Products
    Section 1860D-2(b)(9)(D) of the Act defines ``applicable copayment 
amount'' with respect to a covered insulin product under a PDP or an 
MA-PD plan dispensed during plan year 2026, and each subsequent plan 
year, as the lesser of--
    <bullet> $35;
    <bullet> An amount equal to 25 percent of the maximum fair price 
established for the covered insulin product in accordance with Part E 
of title XI of the Act; or
    <bullet> An amount equal to 25 percent of the negotiated price of 
the covered insulin product under the PDP or MA-PD plan.
    We interpreted the section 1860D-2(b)(9)(D) of the Act reference to 
``applicable copayment amount'' as an amount that could be either a 
fixed copayment or a coinsurance percentage. Therefore, we proposed to 
define this ``applicable copayment amount'' as an ``applicable cost-
sharing amount'' at Sec.  423.100. In addition, to ensure that the 
reference to ``applicable cost-sharing amount'' is specific to the cost 
sharing for covered insulin products described under proposed Sec.  
423.120(h), and discussed in this final rule, we proposed to define the 
term ``covered insulin product applicable cost-sharing amount.''
    Specifically, we proposed to add at Sec.  423.100 a definition of 
``covered insulin product applicable cost-sharing amount'' that means, 
with respect to a covered insulin product covered under a PDP or an MA-
PD plan prior to an enrollee reaching the annual out-of-pocket 
threshold during plan year 2026 and each subsequent plan year, the 
lesser of--
    <bullet> $35;
    <bullet> An amount equal to 25 percent of the maximum fair price 
established for the covered insulin product in accordance with Part E 
of title XI of the Act; or
    <bullet> An amount equal to 25 percent of the negotiated price, as 
defined in Sec.  423.100, of the covered insulin product under the PDP 
or MA-PD plan.
    For example, the August 15, 2024 publication ``Medicare Drug Price 
Negotiation Program: Negotiated Prices for Initial Price Applicability 
Year 2026'' establishes the maximum fair price for the covered insulin 
product Fiasp; Fiasp FlexTouch; Fiasp PenFill; NovoLog; NovoLog 
FlexPen; NovoLog PenFill as $119 for a 30-day supply in CY 2026.\12\ 
If, in this example, a plan's negotiated price, as defined in Sec.  
423.100, is $95, then an amount equal to 25 percent of the maximum fair 
price is $29.75 and an amount equal to 25 percent of the negotiated 
price is $23.75. Therefore, the covered insulin product applicable 
cost-sharing amount would be $23.75, as it is the lesser of $35, 
$29.75, and $23.75.

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

    We received the following comments on this section of the proposed 
rule, and our responses follow:
    Comment: Several commenters requested clarification regarding the 
applicable cost-sharing amount for covered insulin products that are 
selected drugs under the Medicare Drug Price Negotiation Program, as 
established by sections 11001 and 11002 of the IRA and added to 
sections 1191 through 1198 of the Act. As described in section 1860D-2 
of the Act, and our proposed definition of ``covered insulin product 
applicable cost-sharing amount'' at Sec.  423.100, this amount is the 
lesser of $35, an amount equal to 25 percent of the maximum fair price 
(MFP), or an amount equal to 25 percent of the negotiated price. Some 
of these commenters expressed concern regarding the existing guidance 
for managing situations in which the applicable cost-sharing amount is 
determined to be equal to 25 percent of the MFP established for the 
covered insulin product in accordance with Part E of title XI of the 
Act. A few commenters noted that the MFP only includes the ingredient 
cost of a covered insulin product and does not include taxes and 
dispensing fees and requested guidance on how plan sponsors should 
treat these costs. A commenter, referring to dispensing fees but not 
sales tax, noted that if reimbursement for covered insulin product 
claims does not include reimbursement for the ingredient cost of the 
insulin product and a dispensing fee, below cost or inadequate 
reimbursement may harm pharmacies and limit beneficiary access to 
insulin. Other commenters, referring to both sales tax and dispensing 
fees, requested that these costs be included as part of the applicable 
copayment amount when it is equal to 25 percent of the MFP, which they 
note would be consistent with how cost sharing is calculated when 25 
percent of the negotiated price is the applicable cost-sharing amount.
    Response: We thank the commenters for their comments. The MFP 
established for a covered insulin product in accordance with Part E of 
title XI of the Act only includes the ingredient cost of the insulin 
product. As such, the amount paid by an enrollee for a 1-month supply 
of a covered insulin product cannot exceed 25 percent of the MFP, if 
this amount is lower than $35 or 25 percent of the negotiated price. 
Therefore, Part D plans are responsible for covering the cost of the 
dispensing fee and any applicable sales tax. If the applicable covered 
insulin product applicable cost-sharing amount is determined to be 25 
percent of the negotiated price, we note that, consistent with the 
definition of negotiated price Sec.  423.100, this price includes all 
price concessions from network pharmacies or other network providers as 
well as dispensing fees. If the applicable covered insulin product 
applicable cost-sharing amount is determined to be $35, the amount paid 
by an enrollee cannot exceed $35.

[[Page 15804]]

    Comment: A commenter recommended that CMS consider allowing the 
establishment of a copayment amount for insulin products that provides 
flexibility for Part D plan sponsors. Specifically, the commenter 
recommended that CMS permit plans to set a copayment that is equal to 
no more than 25 percent of the MFP or the negotiated price, while also 
allowing for a $35 copay when it is less than 25 percent of the MFP or 
the negotiated price. The commenter asserted that this approach would 
provide flexibility for Part D sponsors, ensure enrollees are subject 
to predictable cost sharing, and encourage pharmaceutical manufacturers 
to maintain or lower prices of covered insulin products.
    Response: We appreciate the commenter's suggestion. In accordance 
with the statute, plans are permitted to set a copayment that is less 
than or equal to $35 so long as that copayment amount is no more than 
25 percent of the MFP or 25 percent of the negotiated price. However, 
it is not clear if the commenter is asking whether the copayment can be 
greater than $35 as long as it is equal to no more than 25 percent of 
the MFP or the negotiated price. While a plan may establish a copayment 
that is equal to or less than $35, we clarify that the copayment cannot 
exceed $35 even if such copayment would otherwise be equal to no more 
than 25 percent of the MFP or the negotiated price. While we recognize 
the importance of allowing Part D sponsors to have some flexibility in 
how they structure their benefits, the covered insulin product 
applicable cost-sharing amount that we are codifying in this rule is 
statutorily defined in section 1860D-2(b)(9)(D) of the Act as the 
lesser of $35, an amount equal to 25 percent of the MFP, and an amount 
equal to 25 percent of the negotiated price. As noted in the proposed 
rule, Part D sponsors have the flexibility to meet this cost-sharing 
requirement by establishing a copayment amount that is equal to or 
lower than $35 for a 1-month supply, establishing a coinsurance 
percentage that is equal to or lower than 25 percent of the product's 
MFP or negotiated price, or establishing both a copayment amount equal 
to or lower than $35 and a coinsurance percentage equal to or lower 
than 25 percent of the product's MFP or negotiated price.
    We clarify that if a Part D sponsor places a covered insulin 
product on a formulary tier with a copayment or coinsurance that is 
lower than the statutory maximum cost-sharing amount (that is, the 
lesser of $35, 25 percent of the negotiate price, or 25 percent of the 
MFP), the Part D sponsor will need to use the copayment or coinsurance 
amount specified for the tier when determining the enrollee's cost-
sharing amount. For example, if a covered insulin product is placed on 
a formulary tier with a copayment amount of $20, the enrollee's cost-
sharing amount would be the lesser of $20, 25 percent of the negotiated 
price, or 25 percent of the MFP, if the insulin product is a selected 
drug. Similarly, if a covered insulin product is placed on a formulary 
tier with a coinsurance percentage of 20 percent, the enrollee's cost-
sharing amount would be the lesser of the 20 percent coinsurance or 
$35.
    We also clarify that if a Part D sponsor places a covered insulin 
product on a formulary tier with a copayment or coinsurance that is 
greater than the statutory maximum cost-sharing amount, the Part D 
sponsor will still need to use the defined covered insulin product 
applicable cost-sharing amount to ensure that the enrollee's cost 
sharing does not exceed such amount. For example, if a covered insulin 
product is placed on a formulary tier with a copayment amount of $50, 
the enrollee's cost-sharing amount cannot exceed the covered insulin 
product applicable cost-sharing amount, which is defined as the lesser 
of $35, 25 percent of the negotiated price, or 25 percent of the MFP. 
Similarly, if a covered insulin product is placed on a formulary tier 
with a coinsurance percentage of 30 percent, the enrollee's cost-
sharing amount cannot exceed the covered insulin product applicable 
cost-sharing amount, which is defined as the lesser of $35, 25 percent 
of the negotiated price, or 25 percent of the MFP.
    Comment: A commenter requested that CMS adjust how it describes the 
applicable cost-sharing amount for covered insulin products. The 
commenter stated that the current guidance stating that cost sharing is 
equal to or lower than $35 or 25 percent of the MFP or the negotiated 
price is unclear. The commenter recommended rewording this requirement 
to state that cost sharing cannot exceed the maximum cost sharing of 
the lower of $35 per month, 25 percent of the MFP, or the negotiated 
price.
    Response: We thank the commenter for their suggestion. However, we 
decline to adopt this change as we believe the current language 
describing the covered insulin product applicable cost-sharing amount 
is sufficiently clear.
4. Cost Sharing for Covered Insulin Products
    Section 1860D-2(b)(9)(A) of the Act specifies that for plan year 
2023 and subsequent plan years, the deductible, as described in section 
1860D-2(b)(1) of the Act, shall not apply with respect to any covered 
insulin product. Section 1860D-2(b)(9)(B)(ii) of the Act further 
specifies that for 2025 and subsequent plan years, the coverage 
provides benefits for any covered insulin product, prior to an 
individual reaching the out-of-pocket threshold, with cost sharing for 
a month's supply that does not exceed the applicable copayment amount. 
We proposed to codify these requirements at Sec.  423.120(h)(1) and 
(2).
a. Duration of Supply
    In alignment with the guidance in our September 26, 2022 HPMS 
memorandum, we proposed to interpret the section 1860D-2(b)(9) cost-
sharing requirements to apply separately to each prescription fill that 
is dispensed. For a prescription fill dispensed in an amount up to a 1-
month supply, $35 (or a lower amount specified by the sponsor) is 
considered a copayment for purposes of determining the ``covered 
insulin product applicable cost-sharing amount.'' In the proposed rule, 
and consistent with our current policy in the September 26, 2022 HPMS 
memorandum, we specified that Part D sponsors would not be required to 
prorate the $35 copayment if less than a 1-month supply is dispensed. 
We believe this proposed policy is supported by section 1860D-
2(b)(9)(D) of the Act, which does not explicitly require prorating the 
applicable copayment amount for less than a 1-month supply. It also 
aligns with current regulations because insulin is not a solid oral 
dosage form subject to daily cost-sharing requirements at Sec.  
423.153(b)(4). In the proposed rule, we stated that if the ``covered 
insulin product applicable cost-sharing amount'' is a coinsurance, the 
coinsurance percentage would be applied to the negotiated price 
regardless of the days' supply dispensed.
    With respect to extended-day supplies (that is, greater than a 1-
month supply) of covered insulin products, we proposed that cost 
sharing must not exceed the cumulative ``covered insulin product 
applicable cost-sharing amount'' that would apply if the same days' 
supply was dispensed in the fewest number of 1-month supply increments 
necessary. For example, if a covered insulin product is dispensed for 
greater than a 1-month supply, but less than a 2-month supply, the 
lesser of $70 or 25 percent of MFP or negotiated price, whichever 
applies, would remain the maximum cost-sharing amount. Similarly, the 
lesser of $105 or 25 percent of the MFP or negotiated price,

[[Page 15805]]

whichever applies, would apply for a covered insulin product that is 
dispensed for greater than a 2-month supply up to a 3-month supply. If 
the ``covered insulin product applicable cost-sharing amount'' is a 
coinsurance, the coinsurance percentage would be applied to the 
negotiated price regardless of the days' supply dispensed.
    While Part D sponsors must not charge cost sharing that exceeds the 
``covered insulin product applicable cost-sharing amount,'' Part D 
sponsors may charge cost sharing that is equal to or less than the 
``covered insulin product applicable cost-sharing amount.'' This means 
that Part D sponsors have the flexibility to specify cost sharing that 
is equal to or lower than the lesser of: a $35 copayment, or 25 percent 
coinsurance based on the MFP (if established for such product under the 
Medicare Drug Price Negotiation Program for that year), or 25 percent 
coinsurance based on the negotiated price. Part D sponsors could meet 
this cost-sharing requirement by establishing a copayment amount that 
is equal to or lower than $35 for a 1-month supply, establishing a 
coinsurance percentage that is equal to or lower than 25 percent of the 
product's MFP or negotiated price, or establishing both a copayment 
amount equal to or lower than $35 and a coinsurance percentage equal to 
or lower than 25 percent of the product's MFP or negotiated price.
b. Out-of-Network Claims
    In the September 26, 2022 HPMS memorandum, we provided guidance on 
managing out-of-network claims. Consistent with this guidance, we 
proposed that enrollees who submit direct member reimbursement (DMR) 
requests for covered insulin products accessed at either out-of-network 
pharmacies or providers (in accordance with Sec.  423.124(a) and (c)), 
or at in-network pharmacies or providers, must not pay more than the 
``covered insulin product applicable cost-sharing amount.'' While Part 
D sponsors generally may charge the enrollee for the difference between 
the cash price and plan allowance for DMRs for covered Part D drugs 
accessed from both out-of-network and in-network pharmacies, neither 
Sec.  423.124(b) nor Chapter 14 of the Prescription Drug Benefit Manual 
directly addresses covered Part D drugs that have statutorily limited 
cost sharing.\13\ Therefore, for covered insulin products accessed at 
either out-of-network pharmacies or providers (in accordance with Sec.  
423.124(a) and (c)), or at in-network pharmacies or providers, we 
proposed at Sec.  423.120(h)(4) that the Part D sponsor must reimburse 
the enrollee for the full cash price paid to the pharmacy or provider 
for a covered insulin product minus the ``covered insulin product 
applicable cost-sharing amount.''
---------------------------------------------------------------------------

    \13\ Section 423.124(b) currently states that a Part D sponsor 
that provides its Part D enrollees with coverage other than defined 
standard coverage may require its Part D enrollees accessing covered 
Part D drugs at out-of-network pharmacies to assume financial 
responsibility for any differential between the out-of-network 
pharmacy's (or provider's) usual and customary price and the Part D 
sponsor's plan allowance. Section 50.4.3 of Chapter 14 of the 
Medicare Prescription Drug Benefit Manual (<a href="https://www.cms.gov/medicare/prescription-drug-coverage/prescriptiondrugcovcontra/downloads/chapter-14-coordination-of-benefits-v09-17-2018.pdf">https://www.cms.gov/medicare/prescription-drug-coverage/prescriptiondrugcovcontra/downloads/chapter-14-coordination-of-benefits-v09-17-2018.pdf</a>) 
provides detailed guidance on how Part D sponsors must process DMR 
requests that are submitted by enrollees who paid cash at an out-of-
network (or an in-network) pharmacy (or provider) and where the 
pharmacy (or provider) did not submit claim to Part D plan.
---------------------------------------------------------------------------

    The total gross covered drug cost (TGCDC) usually is reported 
differently on prescription drug events (PDEs) depending on whether the 
drug was accessed at an out-of-network or in-network pharmacy or 
provider. Specifically, Part D sponsors report the cash price that the 
enrollee paid to the pharmacy or provider as the TGCDC for out-of-
network DMRs but only report the negotiated price as the TGCDC for in-
network DMRs. However, we clarified in the proposed rule that with 
respect to covered insulin products, as an exception to the Chapter 14 
guidance, the sponsor should report the cash price paid to the pharmacy 
or provider as the TGCDC on the PDE for both out-of-network and in-
network DMRs. Additionally, true out-of-pocket (TrOOP) cost 
accumulation for covered insulin products would be limited to the 
beneficiary's cost-sharing amount, which cannot exceed the ``covered 
insulin product applicable cost-sharing amount.''
c. Tier Placement & Utilization Management
    As described in the April 4, 2023 HPMS memorandum, Part D sponsors 
may place covered insulin products on any tier, and apply utilization 
management strategies (for example, prior authorization and step 
therapy), insofar as such tier placement or utilization management 
strategy is consistent with the requirements of CMS's formulary review 
and approval process under Sec.  423.120(b). However, regardless of a 
covered insulin product's tier placement or applicable utilization 
management strategy, the statutory cost-sharing limits described in 
this section of the final rule still apply.
    We proposed to codify at Sec.  423.120(h)(1) and (2) that with 
respect to coverage of a covered insulin product, as we proposed to 
define such term at Sec.  423.100, prior to an enrollee reaching the 
annual out-of-pocket threshold, a Part D sponsor must not apply a 
deductible and must ensure any enrollee cost sharing for each 
prescription fill up to a 1-month supply does not exceed the ``covered 
insulin product applicable cost-sharing amount'' as defined at Sec.  
423.100. We also proposed to codify at Sec.  423.120(h)(3) that Part D 
sponsors must ensure that any enrollee cost sharing for each 
prescription fill greater than a 1-month supply does not exceed the 
cumulative ``covered insulin product applicable cost-sharing amount,'' 
that would apply if the same days' supply was dispensed in the fewest 
number of 1-month supply increments necessary. Finally, we proposed to 
codify at Sec.  423.120(h)(4) that these cost-sharing requirements 
apply for covered insulin products obtained from either in-network or 
out-of-network pharmacies and providers.
    We received the following comments on this section of the proposed 
rule, and our responses follow:
    Comment: A few commenters requested that we monitor out-of-network 
claims for covered insulin products, stating that they believe there 
are limited circumstances in which a beneficiary would need to obtain a 
covered insulin product from an out-of-network pharmacy, especially 
considering the existing requirements for pharmacy networks and the 
availability of mail order prescriptions. The commenters recommended 
that CMS analyze utilization data and determine if out-of-network fills 
for covered insulin products are routinely being used without a 
particular need. The commenters asserted that routine use of out-of-
network fills may interfere with Part D plans' care coordination and 
recommend that limits be placed on access to covered insulin products 
at out-of-network pharmacies.
    Response: We agree with the commenters that out-of-network access 
should not routinely be used to access covered insulin products. We 
reiterate our existing requirements at Sec.  423.124, under which a 
Part D sponsor must ensure that enrollees have access to covered Part D 
drugs at out-of-network pharmacies only if they cannot reasonably be 
expected to obtain such drugs at a network pharmacy and do not access 
covered Part D drugs at an out-of-network pharmacy on a routine basis.

[[Page 15806]]

Moreover, Sec.  423.124(c) requires Part D sponsors to establish 
reasonable rules to appropriately limit out-of-network access to 
covered Part D drugs.
    Comment: A commenter requested clarification on whether direct 
member reimbursement (DMR) requests for covered insulin products can 
only be submitted by beneficiaries or whether DMR requests can also be 
submitted by providers. The commenter recommended that CMS monitor 
claims for covered insulin products, as the codification of CMS's cost-
sharing requirements for insulin products could increase both the plan 
and CMS's liability. The commenter also stated that because there is no 
limit on the price of covered insulin products that are not selected 
drugs under the Medicare Drug Price Negotiation Program, it is possible 
that pharmacies may decline to process network claims online and 
instead recommend that beneficiaries submit paper claims directly to 
their Part D plan in an attempt to charge higher prices at the point-
of-sale and receive higher payments.
    Response: We thank the commenter for sharing their questions and 
recommendations regarding DMR requests. We note that our reference to 
DMR requests in the proposed and final rules is specific to 
beneficiary-submitted requests where a beneficiary is requesting 
reimbursement for a covered insulin product for which they incurred 
out-of-pocket costs. With respect to DMR requests submitted by 
beneficiaries for prescriptions obtained from in-network pharmacies, 
Sec.  423.120(c)(3) specifies that a Part D sponsor must require its 
network pharmacies to submit claims to the Part D sponsor or its 
intermediary whenever the card described in Sec.  423.120(c)(1) is 
presented or on file at the pharmacy unless the enrollee expressly 
requests that a particular claim not be submitted to the Part D sponsor 
or its intermediary. Network pharmacies that decline to process network 
claims online and instead recommend that beneficiaries submit paper 
claims would be in violation of this requirement. We continue to expect 
DMR requests for prescriptions obtained from network pharmacies to be 
limited and submitted only for reasons such as the claims processing 
systems being temporarily unavailable for the pharmacy or the Part D 
sponsor or its intermediary when the enrollee obtains their 
prescription. Any post-reimbursement reconciliation between the network 
pharmacy and plan sponsor would be a contractual matter between the 
parties.
    Comment: A commenter opposed a cumulative covered insulin product 
applicable cost-sharing amount. The commenter stated that cost sharing 
is determined on a claim-by-claim basis and interpreted the language in 
the proposed rule to require that Part D sponsors track cost sharing 
for extended-day supply claims and ensure that the cost sharing does 
not exceed one of the cost-sharing thresholds cumulatively.
    Response: We clarify that the reference to ``the cumulative 
`covered insulin product applicable cost-sharing amount' '' in the 
proposed rule was not intended to require assessment across multiple 
covered insulin product claims. The covered insulin product's 
applicable cost-sharing amount is assessed on a claim-by-claim basis. 
For extended-day supplies, the applicable cost-sharing amount is 
determined based on the days' supply for the individual claim. For 
example, if a covered insulin product is dispensed with a days' supply 
greater than 1 month, but less than 2 months, the lesser of $70, 25 
percent of the MFP, or 25 percent of the negotiated price would be the 
applicable cost-sharing amount. In other words, the Part D sponsor only 
needs to look at the days' supply for an individual claim to determine 
the applicable cost-sharing amount for a covered insulin product.
    Comment: A commenter stated that monthly prescriptions for insulin 
can create challenges for patients. The commenter requested that CMS 
allow quarterly prescriptions for insulin.
    Response: We do not prohibit prescriptions for covered insulin 
products from being written and dispensed for greater than 1-month 
supplies. In the proposed rule, we provided guidance on how to apply 
cost sharing for extended-day supplies of covered insulin products. We 
also proposed to codify at Sec.  423.120(h)(3) that Part D sponsors 
must ensure that any enrollee cost sharing for each prescription fill 
greater than a 1-month supply does not exceed the cumulative ``covered 
insulin product applicable cost-sharing amount,'' that would apply if 
the same days' supply was dispensed in the fewest number of 1-month 
supply increments necessary.
    After considering the public comments we received, and for the 
reasons set forth in the proposed rule and in our responses to 
comments, we are finalizing the changes to Sec. Sec.  423.100 and 
423.120 as proposed.

C. Medicare Prescription Payment Plan (Sec. Sec.  423.137, 423.2265, 
423.2267, and 423.2536)

1. Background
    The Inflation Reduction Act of 2022 (IRA) (Pub. L. 117-169) made 
several additions and amendments to the Social Security Act (the Act) 
that affect the structure of the defined standard Part D drug benefit. 
Section 11202 of the IRA (Maximum Monthly Cap on Cost-Sharing Payments 
under Prescription Drug Plans and MA-PD Plans) added a new section 
1860D-2(b)(2)(E) to the Act requiring all Medicare prescription drug 
plans to offer their Part D enrollees the option to pay out-of-pocket 
(OOP) Part D drug costs through monthly payments over the course of the 
plan year instead of at the pharmacy point of sale (POS) beginning 
January 1, 2025.
    As described in the proposed rule, CMS undertook consumer focus 
group testing to select a name for the program established at section 
1860D-2(b)(2)(E) of the Act that would resonate with Medicare Part D 
enrollees. After multiple rounds of consumer testing fieldwork and 
evaluation of the results, CMS announced the official name of the 
program as the ``Medicare Prescription Payment Plan.'' We refer to the 
program herein using this name.
    As described in more detail in the proposed rule, section 11202(c) 
of the IRA directs the Secretary to implement the Medicare Prescription 
Payment Plan for 2025 by program instruction or other forms of program 
guidance. In accordance with the law, CMS released the Medicare 
Prescription Payment Plan: Final Part One Guidance on Select Topics, 
Implementation of Section 1860D-2 of the Social Security Act for 2025, 
and Response to Relevant Comments (``final part one guidance'') and 
Medicare Prescription Payment Plan: Final Part Two Guidance on Select 
Topics, Implementation of Section 1860D-2 of the Social Security Act 
for 2025, and Response to Relevant Comments (``final part two 
guidance''), establishing critical operational, technical, and 
communication requirements for the Medicare Prescription Payment Plan 
for 2025. CMS does not have authority to implement the Medicare 
Prescription Payment Plan through program instruction authority beyond 
2025. As such, we pursued rulemaking to codify the requirements of the 
program for 2026 and subsequent years.
    With only a few exceptions, we proposed to codify, without 
modification, the requirements established in the final part one 
guidance and the final part two

[[Page 15807]]

guidance at Sec.  423.137 for 2026 and subsequent years.
    CMS's approach in codifying the requirements established in the 
final part one guidance and final part two guidance is to limit changes 
to the requirements already set forth and allow stakeholders to gain 
experience with the program, minimize additional burden for Part D plan 
sponsors, and minimize disruption for Medicare Prescription Payment 
Plan participants. Instances where we proposed to make modifications to 
the requirements previously finalized for 2025 include--
    <bullet> Modifications to the requirements for how Part D plan 
sponsors handle adjustments for Part D claims under the Medicare 
Prescription Payment Plan; and
    <bullet> Modifications to the timing requirements for the grace 
period and initial notice of failure to pay.
    We also proposed new requirements for the following three 
additional topics:
    <bullet> Requirements related to participation renewal for existing 
participants in the Medicare Prescription Payment Plan and addition of 
a renewal notice to the required notices related to election into the 
program.
    <bullet> Requirements for the effective date of voluntary 
terminations from the program.
    <bullet> Requirements for Part D plans to provide pharmacies with 
easily accessible information on a Part D enrollee's costs incurred 
under the program.
    In addition, we proposed to modify Sec.  423.2267(e), which lists 
CMS-required materials and content for Part D plan sponsors, to include 
model and standardized materials for the Medicare Prescription Payment 
Plan, and to modify the list of required content for Part D plan 
sponsor websites at Sec.  423.2265 to include Medicare Prescription 
Payment Plan information. We further proposed to modify Sec.  423.2536 
to waive requirements related to the Medicare Prescription Payment Plan 
for the Limited Income Newly Eligible Transition (LI NET) program.
    Finally, section 1103 of Title I, Subpart B of the Health Care and 
Education Reconciliation Act (Pub. L. 111-152) amended section 1857(e) 
of the Act to add a medical loss ratio (MLR) requirement to Medicare 
Part C (MA program). An MLR is expressed as a percentage, generally 
representing the percentage of revenue used for patient care rather 
than for such other items as administrative expenses or profit. Because 
section 1860D-12(b)(3)(D) of the Act adopts by reference the 
requirements of section 1857(e) of the Act, these MLR requirements also 
apply to the Medicare Part D program. Consistent with the inclusion of 
plan losses in the administrative expense portion of the Part D bid and 
the treatment of Medicare Prescription Payment Plan unsettled balances 
as administrative costs under section 1860D-2(b)(2)(E)(v)(VI) of the 
Act, in the proposed rule, we proposed to modify Sec. Sec.  
422.2420(b)(4)(i)(D) and 423.2420(b)(4)(i)(D) to codify the exclusion 
of such balances from the MLR numerator, a policy which CMS initially 
established in the final part two guidance for 2025.
    Comment: Many commenters expressed support for the Medicare 
Prescription Payment Plan program. Commenters stated that the program 
addresses the burden of high OOP costs early in the year and can 
improve access to medications and avoid financial hardship, 
particularly for those on fixed incomes or managing multiple chronic 
conditions. Commenters also expressed support for CMS's proposal to, 
with only a few exceptions, codify, without modification, the 
requirements established in the final part one guidance and final part 
two guidance. A commenter expressed that the guidance was developed 
after extensive stakeholder input, and the commenter believes it 
reflects an appropriate balance between bureaucratic processes and a 
positive consumer experience.
    Response: CMS thanks the commenters for their support.
    Comment: Some commenters expressed opposition to CMS's proposal to 
codify the Medicare Prescription Payment Plan guidance in regulation. A 
commenter requested that CMS delay implementation of the program for at 
least one year to allow for additional stakeholder input, pilot 
testing, and refinement of the program's design. Some commenters 
requested that CMS defer codification of the program, except for 
statutorily required items, until Part D plan sponsors have had more 
time and experience with the Medicare Prescription Payment Plan.
    Response: CMS thanks the commenters for their feedback. As noted in 
the proposed rule, CMS does not have authority to implement the 
Medicare Prescription Payment Plan through program instruction 
authority beyond 2025. As section 1860D-2(b)(2)(E)(i) of the Act 
requires that Part D plan sponsors offer the Medicare Prescription 
Payment Plan for all plan years beginning on or after January 1, 2025, 
CMS also does not have the authority to delay the implementation of the 
Medicare Prescription Payment Plan. Although CMS is required to pursue 
rulemaking to codify the program at this time, CMS has pursued an 
approach of, with only a few exceptions, codifying the requirements 
established in the final part one guidance and final part two guidance 
at Sec.  423.137 for 2026 and subsequent years without modification in 
order to allow stakeholders to gain experience with the program, 
minimize additional burden for Part D plan sponsors, and minimize 
disruption for Medicare Prescription Payment Plan participants. 
Codifying only certain requirements would cause considerable confusion 
and disruption in the administration of the Medicare Prescription 
Payment Plan.
    CMS remains committed to engaging with shareholders through 
interview series, individual meetings, and other fora, and 
incorporating feedback into future rulemaking, as applicable, as Part D 
plan sponsors gain more experience with the program.
    Comment: Some commenters expressed opposition to CMS making any 
modifications to the Medicare Prescription Payment Plan program for 
2026 and subsequent years, even certain limited modifications. 
Commenters expressed that Part D plan sponsors will need time to 
continue assessing and implementing the required changes and that, 
given the extensive changes to the Part D program taking effect in 
2025, finalizing additional, significant requirements on Part D plan 
sponsors for 2026 and 2027 is premature. A commenter recommended that 
CMS not impose new requirements for 2026 unless the requirements 
provide Part D plan sponsors more flexibility and are optional rather 
than mandatory.
    Response: CMS thanks the commenters for their feedback. CMS agrees 
that limiting changes to the requirements in place for 2025 will allow 
stakeholders to gain experience with the program, minimize additional 
burden for Part D plan sponsors, and minimize disruption for Medicare 
Prescription Payment Plan participants. Accordingly, CMS is not 
finalizing any requirements for real-time election or for Part D plans 
to provide pharmacies with easily accessible information on a Part D 
enrollee's costs incurred under the program. CMS believes that the 
limited modifications to the Medicare Prescription Payment Plan 
codified in this final rule will improve the efficiency of the program 
and minimize disruptions for program participants. CMS has addressed 
specific comments related to real-time election and automatic renewal 
in section II.C.2.(c). of this final rule and comments related to 
providing pharmacies with easily

[[Page 15808]]

accessible information on a Part D enrollee's costs in section 
II.C.2.(i). of this final rule. CMS remains committed to engaging with 
stakeholders and incorporating feedback into future rulemaking, as 
applicable, as stakeholders gain more experience with the program.
    Comment: A commenter expressed concern that the complexity of the 
Medicare Prescription Payment Plan program could cause beneficiary 
confusion. The commenter expressed concern that beneficiaries who fail 
to opt in correctly or inadvertently miss payments may experience 
disruptions in their access to essential medications, placing their 
health at significant risk. The commenter further stated that 
beneficiaries who struggle to meet their monthly installment 
obligations due to unforeseen financial hardships could face increased 
stress and uncertainty, potentially exacerbating existing health 
disparities.
    Response: CMS appreciates the commenter's feedback. CMS understands 
that the Medicare Prescription Payment Plan program is complex and 
believes that ongoing robust efforts to educate beneficiaries about the 
program by CMS, plan sponsors, and other interested parties will be 
important to ensuring that beneficiaries are appropriately informed 
about the program. In 2024, CMS developed educational materials and 
tools to help beneficiaries assess whether the program is right for 
them and raise awareness of other financial assistance programs, such 
as the Low-Income Subsidy (LIS) Program, and encouraged Part D plan 
sponsors and other interested parties to use the language and examples 
in the CMS-developed materials to craft their own educational 
materials.
2. Proposed Provisions
a. Basis, Scope, and General Rule
    Section 1860D-2(b)(2)(E)(i) of the Act requires that each 
prescription drug plan (PDP) sponsor offering a prescription drug plan 
and each MA organization offering a Medicare Advantage prescription 
drug (MA-PD) plan must provide to any enrollee of such plan, including 
an enrollee who is a subsidy eligible individual (as defined in 
paragraph (3) of section 1860D-14(a) of the Act), the option to elect, 
with respect to a plan year, to pay cost sharing under the plan in 
monthly amounts that are capped in accordance with section 1860D-
2(b)(2)(E) of the Act.
    In the proposed rule, CMS stated that the provision applies to all 
Part D plan sponsors, including both stand-alone PDPs and MA-PD plans, 
as well as Employer Group Waiver Plans (EGWPs), cost plans, and 
demonstration plans. CMS further stated that for the reasons 
articulated in the final part two guidance, we do not expect plans that 
exclusively charge $0 cost sharing for covered Part D drugs to offer 
enrollees the option to pay their OOP costs through monthly payments 
over the course of the plan year or otherwise comply with the Medicare 
Prescription Payment Plan requirements set forth in the proposed rule 
and in the proposed new regulation at Sec.  423.137.
    In the proposed rule, we proposed to codify at Sec.  423.137(a) the 
requirements we established in the final part one guidance and final 
part two guidance to apply to plan year 2026 and subsequent years and, 
in the case of a plan operating on a non-calendar year basis, for the 
portion of the plan year starting on January 1, 2026. As explained in 
more detail in the proposed rule at 89 FR 99356, we intend to not 
expect plans operating on a non-calendar year basis to comply with the 
Medicare Prescription Payment Plan requirements set forth in this final 
rule and in the new regulations finalized at Sec.  423.137 to the 
extent that those requirements differ from those established in the 
final part one guidance and final part two guidance during any portion 
of the non-calendar plan year that starts in 2025 and continues into 
2026.
    We also proposed to codify our existing definitions first 
established in the final part one guidance at Sec.  423.137(b) for plan 
year 2026 and subsequent years with certain clarifications. 
Specifically, at Sec.  423.137(b)(1), we proposed to define ``OOP costs 
for the Medicare Prescription Payment Plan'' as the cost sharing amount 
the Part D enrollee is directly responsible for paying. In the final 
part one guidance and final part two guidance, we referred to these 
costs simply as ``OOP costs.'' We also proposed to codify the more 
specific definition of ``OOP costs for the Medicare Prescription 
Payment Plan'' to avoid confusion with other uses of the term OOP 
costs, which may be inconsistent with the use of that term in the final 
part one guidance and final part two guidance.
    As described in the proposed rule at 89 FR 99356 and section 
II.C.2.(b) of this final rule, the formula for calculating the maximum 
monthly cap differs for the first month of participation in the program 
versus the remaining months of the year. The cap for the first month 
for which the Part D enrollee has opted into the Medicare Prescription 
Payment Plan incorporates an enrollee's True Out-of-Pocket costs 
(TrOOP) prior to election into the program.\14\ However, the subsequent 
month calculation is determined by calculating the sum of any remaining 
OOP costs owed by the participant from a previous month that have not 
yet been billed and any additional OOP costs for the Medicare 
Prescription Payment Plan in the subsequent month. As such, for the 
subsequent month calculation of the Part D cost sharing incurred by the 
Part D enrollee, the term ``OOP costs for the Medicare Prescription 
Payment Plan'' includes those Part D cost sharing amounts that the 
enrollee is responsible for paying after accounting for amounts paid by 
third-party payers.
---------------------------------------------------------------------------

    \14\ TrOOP is spending on covered Part D drugs by the 
beneficiary or on their behalf by certain third parties. TrOOP costs 
determine when a beneficiary becomes an applicable beneficiary for 
the Manufacturer Discount Program, reaches the annual OOP threshold, 
and subsequently enters the catastrophic coverage phase.
---------------------------------------------------------------------------

    Specifically, the OOP costs for the Medicare Prescription Payment 
Plan do not include the covered plan pay amount or other TrOOP-eligible 
amount(s), such as any amount paid by potential third-party payers, 
such as State Pharmaceutical Assistance Programs or charities. 
Additionally, within the definition of OOP costs for the Medicare 
Prescription Payment Plan, we proposed to define ``remaining OOP costs 
owed by the participant'' to be the sum of OOP costs for the Medicare 
Prescription Payment Plan that have not yet been billed to the program 
participant. For example, as described in more detail in section 
II.C.2.(b). of this final rule, if a Medicare Prescription Payment Plan 
participant incurs $2,000 in January and is billed $166.67, the 
remaining OOP costs owed by the participant are $2,000 - $166.67 = 
$1,833.33.
    Finally, pursuant to our authority under section 1860D-14(e)(5)(B) 
of the Act to waive such requirements of title XI and title XVIII of 
the Act as may be necessary to carry out the purposes of the LI NET 
program, we proposed to codify a waiver for the LI NET program with 
respect to the requirements of the Medicare Prescription Payment Plan 
for plan year 2026 and subsequent years. (Because the LI NET sponsor is 
a Part D sponsor and the LI NET contract is a PDP contract, many 
existing provisions in Part 423 apply to LI NET. Certain requirements 
were waived by the statute (such as dissemination of information and 
formulary requirements) and some requirements were waived through 
rulemaking (such as medication therapy management and quality 
improvement

[[Page 15809]]

activities).) Specifically, we proposed to revise Sec.  423.2536 to 
include the proposed Medicare Prescription Payment Plan requirements at 
Sec.  423.137 discussed in this section to the list of Part D 
requirements waived for the LI NET program. We would do this by 
redesignating paragraphs (c) through (k) as paragraphs (d) through (l) 
and adding the new proposed waiver at paragraph (c). In addition, we 
proposed to add the materials proposed at Sec. Sec.  423.2265(b)(16) 
and 423.2267(e)(45) through (51) (that is, information about the 
Medicare Prescription Payment Plan on sponsor websites and forms and 
notices related to the program) to the list of communication 
requirements waived for the LI NET program. We proposed to do this by 
revising newly redesignated Sec.  423.2536(i)(1) and (4).
    Comment: A commenter expressed support for CMS's policy of not 
expecting plans that exclusively charge $0 cost sharing for covered 
Part D drugs to offer enrollees the option to pay their OOP costs 
through monthly payments over the course of the plan year or otherwise 
comply with the Medicare Prescription Payment Plan requirements set 
forth in the proposed rule. The commenter requested that CMS also apply 
that policy to dual eligible special needs plans (D-SNPs) that offer 
nominal cost-sharing. The commenter anticipates that termination of the 
MA Value-Based Insurance Design (VBID) model will reduce the number of 
D-SNPs that can offer $0 copays for Part D drugs and expressed concern 
that an LIS enrollee in a plan with Part D cost sharing could 
experience higher cost-sharing in later months under the Medicare 
Prescription Payment Plan if their cost sharing in the early months of 
a year is shifted to the later months.
    Response: CMS thanks the commenter for their support and feedback. 
CMS does not expect Part D plans that exclusively charge $0 cost 
sharing for covered Part D drugs to all plan enrollees to offer the 
Medicare Prescription Payment Plan because there is no practical 
application for the Medicare Prescription Payment Plan in Part D plans 
that do not charge cost sharing. While CMS recognizes that Part D 
enrollees with low cost sharing may be less likely to benefit from the 
Medicare Prescription Payment Plan, under section 1860D-2(b)(2)(E)(i) 
of the Act, Part D plan sponsors must provide the option to participate 
in the Medicare Prescription Payment Plan to all Part D enrollees, 
including subsidy eligible individuals as defined in paragraph (3)(A) 
of section 1860D-14(a) of the Act. Because the statute explicitly 
requires that the Medicare Prescription Payment Plan be offered to 
subsidy-eligible individuals and because such beneficiaries could 
determine that they would benefit from the Medicare Prescription 
Payment Plan under certain circumstances, D-SNPs that offer nominal 
cost sharing are required to offer the Medicare Prescription Payment 
Plan to their enrollees.
    Comment: A commenter expressed support for CMS's proposal to add 
the Medicare Prescription Payment Plan to the list of Part D 
requirements waived for the LI NET program. Another commenter expressed 
support for the definitions proposed for the Medicare Prescription 
Payment Plan program and stated that they add additional clarity about 
the subset of costs eligible for the program.
    Response: CMS thanks the commenters for their support.
    Comment: A commenter requested that CMS waive Medicare Prescription 
Payment Plan requirements for EGWPs, as the commenter believes the 
program will add significant administrative costs without providing 
meaningful benefits to EGWP enrollees.
    Response: CMS appreciates the commenter's feedback but declines to 
waive the requirement to offer the Medicare Prescription Payment Plan 
for EGWPs. Section 1860D-22(b) of the Act and 42 CFR 423.458(c) permit 
CMS to waive or modify any requirement that hinders the design of, 
offering of, or enrollment in an EGWP. Under section 1860D-
2(b)(2)(E)(i) of the Act, all Part D plan sponsors must provide the 
option to participate in the Medicare Prescription Payment Plan to all 
Part D enrollees. Regardless of whether EGWP enrollees are less likely 
to benefit from the Medicare Prescription Payment Plan than enrollees 
in other types of plans, waiving the requirements of the Medicare 
Prescription Payment Plan would mean that some EGWP beneficiaries who 
would be likely to benefit would not be able to take advantage of the 
program. CMS believes that waiving requirements for EGWPs is not 
aligned with the statutory requirement that all Part D enrollees must 
be provided with the option to participate in the program.
    After considering the comments we received and for the reasons 
outlined in the proposed rule and our responses to comments, we are 
finalizing all proposed provisions at Sec. Sec.  423.137(a) and (b) and 
423.2536 without modification.
b. Calculation of the Maximum Monthly Cap on Cost-Sharing Payments
    Section 1860D-2(b)(2)(E)(iv) of the Act specifies how the monthly 
caps on OOP cost sharing payments are to be calculated. The formula for 
calculating the cap differs for the first month of participation in the 
program versus the remaining months of the year. The maximum monthly 
cap calculations include specifics of a participant's Part D drug costs 
(previously incurred costs and new OOP costs), as well as the number of 
months remaining in the plan year; as such, the amount can vary from 
person-to-person and month-to-month. Assuming a program participant 
remains in the Medicare Prescription Payment Plan through the end of 
the plan year, the total amounts billed monthly through the December 
payment (which would be billed and paid in the following year) will 
equal the total OOP costs for the Medicare Prescription Payment Plan 
during the year.
    Under section 1860D-2(b)(2)(E)(iv)(I) of the Act, for the first 
month for which the Part D enrollee has opted into the Medicare 
Prescription Payment Plan, the term ``maximum monthly cap'' means an 
amount calculated by taking the annual OOP threshold minus any Part D 
costs the Part D enrollee incurred during the year before opting into 
the program, divided by the number of months remaining in the plan 
year. The number of months remaining in the plan year includes the 
current reference month (for example, for a calendar year plan, the 
months remaining in the calculation for the January maximum cap would 
be 12).
    Additionally, incurred costs for the Medicare Prescription Payment 
Plan (as used in the statutory definition of the first month's maximum 
cap calculation) means the incurred costs, with the meaning set forth 
at section 1860D-2(b)(4)(C) of the Act and described in section 30 of 
the Final CY 2025 Part D Redesign Program Instructions (Final 2025 
Program Instructions), that were incurred prior to effectuation of an 
election into the Medicare Prescription Payment Plan, including all 
TrOOP-eligible costs.\15\ If election into the program occurs mid-
month, this would include Part D costs incurred within the calendar 
month of election but prior to election.
---------------------------------------------------------------------------

    \15\ Final CY 2025 Part D Redesign Program Instructions: <a href="https://www.cms.gov/inflation-reduction-act-and-medicare/part-d-improvements">https://www.cms.gov/inflation-reduction-act-and-medicare/part-d-improvements</a>.
---------------------------------------------------------------------------

    Under section 1860D-2(b)(2)(E)(iv)(II) of the Act, for each 
subsequent month for which the Part D enrollee has opted into the 
program, the maximum monthly cap is determined by calculating the sum 
of any remaining OOP costs owed by the participant from a previous 
month that have not yet been billed and any additional OOP costs for

[[Page 15810]]

the Medicare Prescription Payment Plan in the subsequent month, divided 
by the number of months remaining in the plan year. The number of 
months remaining includes the month for which the cap is being 
calculated. This calculation repeats for each month in which the 
participant remains in the Medicare Prescription Payment Plan. The 
resulting maximum monthly cap will change if additional OOP costs for 
the Medicare Prescription Payment Plan are incurred.
    Under section 1860D-2(b)(4)(B)(i)(VII) of the Act, the annual OOP 
cost threshold for 2025 is $2,000. Under section 1860D-
2(b)(4)(B)(i)(VII) of the Act, for 2026 and subsequent years, the 
annual OOP cost threshold is equal to the amount specified for the 
previous year, increased by the annual percentage increase described in 
section 1860D-2(b)(6). ``Incurred costs'' means any costs incurred or 
treated as incurred under section 1860D-2(b)(4)(C) of the Act.
    The proposed rule discussed the specifics of the first and 
subsequent month calculation for the maximum monthly cap on cost-
sharing payments.
    Comment: A commenter expressed support for finalizing the program 
calculations.
    Response: CMS thanks the commenter for their support.
    Comment: A commenter expressed concern that the program 
calculations are not intuitive and may be confusing for program 
participants.
    Response: CMS appreciates the commenter's feedback. However, 
section 1860D-2(b)(2)(E)(iv) of the Act specifies how the maximum 
monthly caps on OOP cost sharing payments are to be calculated, and CMS 
does not have the authority to change the statutory formula for the 
maximum monthly cap.
    After considering the comments we received and for the reasons 
outlined in the proposed rule and our responses to comments, we are 
finalizing all proposed provisions at Sec.  423.137(c) without 
modification.
c. Eligibility and Election
    Under section 1860D-2(b)(2)(E)(i) of the Act, Part D plan sponsors 
must provide the option to opt into the Medicare Prescription Payment 
Plan to all Part D enrollees, including enrollees who are eligible for 
LIS. Consistent with the statute, in the proposed rule, we proposed to 
codify the requirement that Part D sponsors must offer the program to 
all Part D enrollees, including those who are LIS eligible, at Sec.  
423.137(d).
    In addition, under section 1860D-2(b)(2)(E)(v)(III)(aa) of the Act, 
Part D plan sponsors may not restrict the application of the Medicare 
Prescription Payment Plan benefit to specific covered Part D drugs. We 
proposed to codify this requirement for 2026 and subsequent years at 
Sec.  423.137(d)(5).
    Section 1860D-2(b)(2)(E)(v)(II) of the Act also states that a Part 
D enrollee may opt into the Medicare Prescription Payment Plan prior to 
the beginning of the plan year or in any month during the plan year. In 
the proposed rule, we proposed the following requirements for 2026 and 
subsequent years:
    <bullet> Part D plan sponsors must allow Part D enrollees to opt 
into the Medicare Prescription Payment Plan prior to the plan year 
(including the annual coordinated election period for the subsequent 
plan year, the Part D initial enrollment period, and Part D special 
election periods) or at any point during the plan year.
    <bullet> Part D plan sponsors must allow Part D enrollees to opt 
into the Medicare Prescription Payment Plan after the conclusion of an 
enrollment period and before the new plan enrollment effective date 
(for example, an enrollee could opt into the program for the upcoming 
plan year after the conclusion of the annual coordinated election 
period and in advance of the January 1 new plan enrollment effective 
date).
    We also proposed requirements for election into the program. We 
proposed that the Part D enrollee, or their authorized legal 
representative, must complete an election request, provide the required 
information to the Part D plan sponsor, and be approved by the Part D 
plan sponsor to opt into the Medicare Prescription Payment Plan. As 
discussed in more detail in the proposed rule, we also proposed to 
require Part D plan sponsors to have specific election mechanisms 
available to Part D enrollees who wish to opt into the Medicare 
Prescription Payment Plan.
    We further proposed that Part D plan sponsors must consider 
Medicare Prescription Payment Plan election requests regardless of the 
election mechanism or format provided it includes certain information 
necessary to be complete, as described in the proposed rule.
    In the proposed rule, for 2026 and subsequent years, we proposed to 
codify the 24-hour effectuation requirement at Sec.  423.137(d)(4), but 
requested comment on a potential requirement for Part D plan sponsors 
to effectuate election requests received via phone or web in real-time 
for 2026 or future years, including the operational feasibility of 
implementing a real-time election requirement for 2026, what technology 
and processes would be required to enable a real-time election 
requirement for 2026, implications for Part D enrollees, and potential 
burden on interested parties. We expressed interest in opportunities 
for pharmacists to support enrollees in using any future Part D plan 
sponsor-adjudicated real-time election mechanisms at the POS.
    We also outlined proposed requirements for receipt of election 
requests and incomplete election requests. We further proposed 
requirements for Part D plan sponsors to process retroactive election 
requests in cases where an enrollee cannot have immediate election into 
the program and believes that any delay in filling a prescription due 
to the 24-hour timeframe required to process a program election request 
may seriously jeopardize their life, health, or ability to regain 
maximum function and so must pay OOP to the pharmacy.
    Section 1860D-2(b)(2)(E)(v)(II) of the Act requires Part D plan 
sponsors to offer the Medicare Prescription Payment Plan to all Part D 
enrollees in any month during the year. At Sec.  423.137(d)(8), for 
2026 and subsequent years, we proposed to codify requirements for mid-
year plan switches, consistent with the requirements included in the 
final part one guidance for 2025. The proposed rule outlined new 
requirements related to participation in the program from year to year, 
a topic CMS did not address in the final part one guidance or final 
part two guidance because the IRA limited CMS's program instruction 
authority to a single year of the program (that is, contract year (CY) 
2025). We proposed requiring Part D plan sponsors to send a notice 
alerting the Part D enrollee that their participation in the program 
will continue into the next year unless they indicate that they would 
like to opt out for the upcoming year. This notice would be required to 
be sent out to program participants by the end of the annual 
coordinated election period (no later than December 7) and must include 
the Part D plan sponsor's program terms and conditions for the upcoming 
year.
    We also addressed other program election communications and notice 
requirements for Part D plan sponsors, including timing, content, and 
supplemental information requirements for the election request form, 
notice of election approval, and notice of denial.
    CMS issued model materials that Part D enrollees can use to fulfill 
the election request and election approval requirements through the 
Medicare Advantage and Prescription Drug Programs: Part C and Part D 
Medicare Prescription Payment Plan Model

[[Page 15811]]

Documents (CMS-10882; OMB 0938-1475) ICR package. As established in 
Sec.  423.2267(c), model materials and content are required materials 
and content created by CMS as an example of how to convey beneficiary 
information. If Part D plan sponsors choose to not use a CMS-developed 
model version of a particular required material or content, they must 
still accurately convey the vital information in the required material 
or content to the beneficiary.
    Comment: A few commenters expressed support for finalizing the 
effectuation timeframes for election requests, including the 24-hour 
effectuation requirement for election requests made during the plan 
year. A commenter requested that plans be able to make exceptions to 
the 24-hour requirement, such as for effectuating election requests 
received via paper form and requested that CMS exercise enforcement 
discretion for effectuation timeframes. Other commenters requested the 
effectuation timeframe for election requests made during the plan year 
be extended to 72 hours.
    Response: CMS thanks the commenters for their feedback. To ensure a 
seamless election process for Part D enrollees and ensure they have 
timely access to the program and their Part D prescriptions, CMS is 
finalizing the requirement for Part D plan sponsors to process election 
requests received during the plan year within 24 hours. Through this 
requirement, CMS reiterates the importance of ensuring that Part D 
enrollees, once they request to participate, are able to access the 
benefits of the program as timely as possible. This is particularly 
important for those who may wait to pick up a prescription until their 
program participation is effectuated. Additionally, CMS emphasizes that 
Part D plan sponsors can encourage those who are likely to benefit from 
the program to opt in prior to the plan year or during the plan year 
prior to going to a pharmacy through strong education and outreach 
efforts.
    In response to comments regarding operational challenges 
effectuating election requests received via the paper form, CMS 
acknowledges these concerns but reiterates the importance of ensuring 
that Part D enrollees gain timely access to the program and their 
prescriptions, regardless of the means of election request.
    Comment: Many commenters expressed support for real-time election, 
stating that it would reduce burden on enrollees, prevent drug 
dispensing delays, and reduce prescription abandonment. Many of these 
commenters acknowledged that plan-facilitated real-time election may 
need to be implemented as a temporary measure but expressed a strong 
preference for a pharmacy-facilitated real-time election process once 
it is technologically feasible.
    However, many commenters opposed requirements for real-time 
election, especially in the early years of the program. These 
commenters pointed to technological and operational challenges with 
real-time election (both plan-facilitated and pharmacy-facilitated) and 
requested additional years of program experience before considering a 
real-time election requirement. In addition, some commenters expressed 
concerns that real-time election processing could impose additional 
pharmacy burden (due to potential workflow disruption or provision of 
program education to enrollees).
    Response: CMS thanks the commenters for their feedback CMS agrees 
that prompt access to the program is important and supports actions by 
Part D plan sponsors to prevent drug dispensing delays and reduce 
prescription abandonment. However, CMS also acknowledges that there are 
technological barriers to industry-wide implementation of real-time 
election for 2026. As noted in the proposed rule, our research 
indicates that there is no mechanism at the POS for program election 
information to be documented in a manner that complies with election 
requirements; technological updates would be needed to support POS 
election. These updates would require significant lead time and 
coordination with industry standards committees that have existing 
processes and timelines outside of CMS's purview.
    While real-time election (facilitated by Part D plan sponsors 
outside of the POS) need not involve changes to the current NCPDP 
Telecommunication Standard, CMS recognizes that additional information 
technology systems modifications may be necessary for sponsor-
facilitated election updates to interface in real-time with the 
pharmacy benefit manager (PBM) and pharmacy systems. Finally, CMS is 
cognizant of potential additional burden pharmacies may face under a 
real-time election option. As such, CMS is not requiring Part D plan 
sponsors to effectuate election requests received via phone or web in 
real-time for 2026. CMS continues to encourage Part D plan sponsors to 
process election requests within timeframes shorter than 24 hours or in 
real-time if they are able.
    Additionally, CMS reiterates the importance of targeted outreach 
prior to the plan year to identify enrollees likely to benefit from the 
program in advance of any POS notifications, which will streamline the 
program election process. This requirement, alongside the 24-hour 
effectuation timeframe during the plan year and the required process to 
retroactively apply the program to those meeting criteria for an urgent 
situation, will reduce the likelihood of dispensing delays and 
prescription abandonment. CMS will continue to evaluate program 
operations and election processes and consider future modifications to 
effectuation requirements.
    Comment: Many commenters expressed support for the proposed 
automatic election renewal process, stating that automatic renewal 
would reduce the burden on Medicare Prescription Payment Plan 
participants. Some commenters opposed the automatic renewal 
requirements, instead suggesting that automatic renewal be optional for 
plans to implement in the early years of the program. Some of these 
commenters also suggested that plans be able to exempt some 
participants from automatic renewal, such as those with unpaid cost 
sharing amounts or those who appear not likely to benefit in the 
upcoming year. A commenter suggested that CMS issue criteria to help 
plans identify a targeted subset of participants for renewal. Another 
commenter requested that participants in long-term care settings be 
exempt from automatic renewal.
    Response: CMS thanks the commenters for their feedback. We agree 
that automatic renewal eases burden for both participants and plan 
sponsors. While there may be some participants who did not meet program 
thresholds for ``likely to benefit'' in the current year or who appear 
not likely to benefit in the upcoming year, we believe that consistent 
standards for participation renewal for all participants promotes the 
cleanest implementation of the program, especially in the early years 
of the Medicare Prescription Payment Plan.
    Comment: Multiple commenters suggested that CMS revise the 
automatic renewal requirements to extend to participants switching 
plans within the same parent organization or Part D plan sponsor. A 
commenter requested that CMS clarify how automatic renewal would work 
with CMS-approved crosswalks.
    Response: CMS thanks the commenters for their questions. The 
automatic renewal requirements are generally intended to align with 
existing

[[Page 15812]]

Part D program enrollment requirements. As such, if a Part D enrollee 
would be required to complete a new enrollment request for the upcoming 
plan year (such as when an enrollee chooses to switch between plan 
benefit packages (PBPs) within the same contract), that enrollee would 
also need to re-elect into the Medicare Prescription Payment Plan. 
Generally, in situations in which the Part D enrollee is not required 
to complete a new Part D enrollment request for the upcoming year (such 
as when someone remains in the same PBP or when their PBP is part of a 
consolidated renewal plan), then the enrollee's participation in the 
Medicare Prescription Payment Plan would also automatically carry over 
for the upcoming year.
    Comment: A commenter requested that CMS clarify when the 
requirement for automatic renewal would start (that is, at the end of 
2025 for CY 2026 or at the end of 2026 for CY 2027).
    Response: Automatic renewal requirements will take effect for the 
CY 2026 plan year. As such, Part D plan sponsors will be required to 
automatically renew Medicare Prescription Payment Plan participation 
for enrollees who are participating in the program in 2025.
    Comment: A couple of commenters requested that CMS update technical 
guidance for the submission of beneficiary-level data elements into the 
MARx Medicare Advantage Prescription Drug (MARx) system upon 
finalization of the rule to reflect the automatic renewal policy.
    Response: CMS thanks the commenters for their recommendations. Any 
potential modifications to the technical guidance for CY 2026 will be 
published in Fall 2025.
    Comment: Many commenters supported the requirement for a separate 
renewal notice, including the requirements to include the Part D plan 
sponsor's program terms and conditions for the upcoming year and a 
reminder that the participant may opt out of the program at any time, 
including for the upcoming plan year. Commenters requested the 
opportunity to review and provide feedback for the renewal notice 
through an Information Collection Request (ICR) process. Some 
commenters suggested alternative mechanisms to notify participants 
about automatic renewal, such as adding language to existing annual 
plan documents (such as the Annual Notice of Change (ANOC) and Evidence 
of Coverage (EOC), the program notice of election approval, or the 
program monthly bill). A commenter also suggested that if a separate 
notice is required, it should be distributed after the annual 
coordinated election period to avoid confusion during times of 
increased plan switching.
    Response: CMS thanks the commenters for their feedback. CMS 
believes that a separate notice is important to clearly communicate to 
Medicare Prescription Payment Plan participants that their program 
participation will continue in the upcoming plan year. The model notice 
will be incorporated into the Medicare Advantage and Prescription Drug 
Programs: Part C and Part D Medicare Prescription Payment Plan Model 
Documents ICR package (CMS-10882; OMB 0938-1475) and will be made 
available to the public for review and comment under the standard non-
rule Paperwork Reduction Act (PRA) process which includes the 
publication of 60- and 30-day Federal Register notices and the posting 
of the collection of information documents on our PRA website. CMS will 
also consider adding educational language related to automatic renewal 
of participation to other Part D materials, such as the ANOC.
    Finally, CMS appreciates the suggestion to delay the timing of the 
required renewal notice until after the annual coordinated election 
period to account for participants who may switch plans for the 
upcoming year and thus not be eligible for automatic renewal. CMS 
agrees that this will reduce beneficiary confusion and promote a more 
efficient automatic renewal process. At Sec.  423.137(d)(10)(iv)(A), 
CMS has modified the timing requirement for the renewal notice in this 
final rule, such that the renewal notice must be sent after the end of 
the annual coordinated election period but prior to the beginning of 
the plan year.
    Comment: A commenter requested that CMS clarify whether, given the 
automatic renewal process, plans would be required to send the program 
fact sheet, paper election request, and ``Medicare Prescription Payment 
Plan Likely to Benefit Notice'' to Part D enrollees currently 
participating in the program.
    Response: CMS appreciates the opportunity to clarify. Part D plan 
sponsors are required to send only the renewal notice to Part D 
enrollees who are currently participating in the Medicare Prescription 
Payment Plan and will be automatically renewed for the upcoming year. 
Part D plan sponsors are not required to perform ``likely to benefit'' 
analyses for current program participants, nor to send the ``Medicare 
Prescription Payment Plan Likely to Benefit Notice.'' We also note that 
although a Part D sponsor may choose to send the Medicare Prescription 
Payment Plan mailing described at Sec.  423.137(m)(1) to all of its 
Part D enrollees or only to a Part D enrollee who is receiving a new 
membership ID card, we encourage Part D sponsors to not send the paper 
enrollment form to current Medicare Prescription Payment Plan 
participants to reduce potential beneficiary confusion.
    Comment: A commenter requested that CMS remove requirements for 
telephonic delivery of the notice of election approval during the plan 
year. The commenter stated that the process adds to plan burden and is 
often confusing for beneficiaries, who have already received a 
confirmation number when they completed the telephone or electronic 
election process.
    Response: CMS thanks the commenter for their feedback. CMS agrees 
that when a Part D plan sponsor is able to fully complete the election 
request process in the course of a telephonic or electronic interaction 
and at that same time provides the enrollee with the effective date of 
their program effectuation (which must be within 24 hours of receipt) 
and satisfies other notice of election approval requirements as 
outlined at Sec.  423.137(d)(10)(ii), then a second telephonic 
notification of election acceptance is redundant. CMS is modifying the 
criteria at Sec.  423.137(d)(10)(ii)(A)(3) to reflect that exception. 
In these cases, the Part D plan sponsor must still deliver the written 
notice within 3 calendar days.
    Comment: A few commenters expressed support for the requirements 
for Part D plan sponsors to include information on the availability of 
the LIS program and other financial assistance programs in the 
election-related materials; a few commenters also requested that 
information about financial assistance programs be added to either the 
election request form or the educational materials required with the 
election request form. A few commenters suggested modifications to the 
requirements for the election request form, including adding language 
stating that enrollees with low, stable drug costs are not likely to 
benefit from the program and adding a field to differentiate election 
requests for the current year versus the upcoming plan year. A 
commenter requested that the period for opting into the Medicare 
Prescription Payment Plan for the upcoming plan year be delayed until 
December 10 (after the end of the annual coordinated election period) 
to allow for plan switching to be completed before processing 
elections.

[[Page 15813]]

    Response: CMS thanks the commenters for their feedback and notes 
that the CMS-developed Medicare Prescription Payment Plan fact sheet 
contains information on programs, like the LIS program (also known as 
Extra Help), that can lower costs for enrollees.\16\
---------------------------------------------------------------------------

    \16\ The Medicare Prescription Payment Plan fact sheet can be 
accessed at <a href="http://medicare.gov/publications">medicare.gov/publications</a>.
---------------------------------------------------------------------------

    As stated in this final rule, Part D plan sponsors are required to 
furnish additional educational information on the Medicare Prescription 
Payment Plan with the election request form and the notice of 
acceptance; Part D plan sponsors are encouraged to use the CMS-
developed educational fact sheet to satisfy requirements to provide 
supplemental information on the program. The fact sheet includes 
language to help enrollees decide if they are likely to benefit from 
participating in the program. With regard to the requested field to 
differentiate the intended year of the election request, CMS will 
consider any changes to the existing model materials through the 
standard non-rule PRA process. Under section 1860D-2(b)(2)(E)(v)(II) of 
the Act, a Part D enrollee may opt into the Medicare Prescription 
Payment Plan prior to the beginning of the plan year or in any month 
during the plan year. CMS believes that requiring Part D plan sponsors 
to allow Part D enrollees to opt into the Medicare Prescription Payment 
Plan prior to the plan year, including during the annual coordinated 
election period for the subsequent year, simplifies the election 
process for Part D enrollees.
    Comment: A commenter expressed support for continuing to require 
telephone and electronic election options. Some commenters suggested 
that program election be integrated into Medicare Plan Finder.
    Response: CMS thanks the commenters for their support and 
suggestions. CMS notes that enhancements were made to Medicare Plan 
Finder starting with CY 2025 to display a cost preview based on a 
consumer's specific drug list, a set of consumer-selected MA or Part D 
plans, and consumer-selected pharmacies, including both retail 
locations and mail order options. However, CMS reiterates that 
participation in the Medicare Prescription Payment Plan is an 
arrangement between the Part D plan sponsor and the Part D enrollee, 
and, as such, Part D plan sponsors are ultimately responsible for 
managing the election process.
    Comment: A few commenters expressed support for CMS's requirement 
that in case of retroactive election, the Part D plan sponsor is 
responsible for reimbursing the participant, not the pharmacy. A 
commenter requested that the timeframe for processing retroactive 
election requests be extended from 24 hours to 72 hours.
    Response: CMS thanks the commenters for their support and feedback. 
CMS is finalizing requirements for retroactive election requests as 
proposed. With respect to retroactive election requests, CMS reiterates 
the importance of ensuring that Part D enrollees, once they request to 
participate, are able to access the benefits of the program as timely 
as possible. CMS believes that this applies equally to a retroactive 
election request as to a non-retroactive request. Accordingly, we are 
finalizing this requirement as proposed.
    After considering the comments we received and for the reasons 
outlined in the proposed rule and our responses to comments, at Sec.  
423.137(d)(9), for 2026 and subsequent years, we are finalizing the 
proposed requirements related to participation renewal, with a 
modification to the timing of the required notice and required 
contents. The notice must be sent after the end of the annual 
coordinated election period but prior to the end of the plan year; Part 
D plan sponsors must include their program terms and conditions for the 
upcoming plan year as part of the renewal notice or as a separate 
attachment. We are also finalizing as proposed those requirements for 
2026 and subsequent years at Sec.  423.137(d)(10)(ii), with one 
modification. In response to comments received, we are modifying the 
criteria for when an initial telephone notice of election approval is 
not required. If a Part D plan sponsor is processing an election 
request over the phone or electronically and at that same time provides 
the enrollee with the effective date of their program effectuation 
(which must be within 24 hours of receipt) and other notice of election 
requirements as outlined at Sec.  423.137(d)(10)(ii), then a second 
telephonic notification of election acceptance is not required. In 
these cases, the Part D plan sponsor must still deliver the written 
notice within 3 calendar days. We are finalizing all other provisions 
as Sec.  423.137(d) as proposed.
d. Part D Enrollee Targeted Outreach
    Consistent with our authority under section 11202 of the IRA and 
under section 1860D-12(b)(3)(D) of the Act, in the proposed rule, we 
proposed to codify the targeted outreach framework and thresholds 
established in the final part one guidance and final part two guidance 
at Sec.  423.137(e). The statute establishes that some Part D enrollees 
will incur OOP costs that make them likely to benefit from election 
into the Medicare Prescription Payment Plan. While this program is open 
to all Part D enrollees, Part D enrollees incurring high OOP costs 
earlier in the plan year are generally more likely to benefit. Section 
1860D-2(b)(2)(E)(v)(III)(dd) of the Act requires that Part D plan 
sponsors have a mechanism in place to notify a pharmacy when a Part D 
enrollee incurs OOP costs with respect to covered Part D drugs that 
make it likely the enrollee may benefit from participating in the 
program. CMS recognizes, however, that notification of Part D enrollees 
likely to benefit from the Medicare Prescription Payment Plan prior to 
reaching the pharmacy POS will be a critical component to program 
success. Therefore, in the 2025 guidance, CMS proposed requirements for 
Part D plan sponsors to undertake targeted outreach, both prior to and 
during the plan year, directly to Part D enrollees likely to benefit 
from the program.
    While the statute requires a likely to benefit notification, it 
does not outline the specific criteria or define the profile of someone 
who is likely to benefit under the program. As discussed in further 
detail in the proposed rule, CMS developed a standardized, quantitative 
framework for assessing ``likely to benefit,'' which was used to inform 
targeted outreach requirements both prior to and during the plan year.
    For 2026 and subsequent years, we proposed to codify at paragraph 
(e)(1)(i)(A) of Sec.  423.137 that a Part D enrollee is likely to 
benefit from participating in the program if the enrollee incurs $600 
or more in OOP costs for a single prescription. Additionally, at 
paragraph (e)(2), we proposed to codify that Part D plan sponsors must 
notify a pharmacy when a Part D enrollee incurs OOP costs for a single 
prescription that equals or exceeds the $600 POS threshold.
    As discussed in the proposed rule, for 2025, CMS required Part D 
plan sponsors to review their Part D claims history from the first 
three quarters of the year and conduct outreach to Part D enrollees who 
incurred at least $2,000 in OOP costs for covered drugs through 
September of 2024. Part D plan sponsors may develop supplemental 
strategies for identification of Part D enrollees likely to benefit 
prior to the plan year. In the proposed rule, for 2026 and subsequent 
years, we proposed to codify, at

[[Page 15814]]

paragraph (e)(1)(i)(B), this likely to benefit criteria and, at 
paragraph (e)(3)(i), the related requirements for Part D plan sponsor 
direct outreach to identified likely to benefit prior to the plan year. 
In addition to these criteria, in the final part two guidance, CMS 
established a requirement for 2025 for Part D plan sponsors to put in 
place reasonable guidelines for ongoing identification of Part D 
enrollees likely to benefit during the plan year. We proposed to codify 
this requirement for ongoing identification and notification of 
enrollees for 2026 and subsequent years at paragraph (e)(3)(ii).
    Based on the required analysis to fulfill requirements at paragraph 
(e)(3) and any additional analysis Part D plan sponsors conduct to 
identify enrollees who may be likely to benefit from this program, we 
proposed to codify at paragraph (e)(4) that the Part D plan sponsor 
must send the standardized ``Medicare Prescription Payment Plan Likely 
to Benefit Notice'' to identified enrollees. We proposed to add this 
notice as a required standardized communication material for Part D 
plan sponsors at Sec.  423.2267(e)(47). Prior to the plan year, the 
notification must occur no later than the end of the annual coordinated 
election period (open enrollment), which is December 7 of each year. We 
proposed that this outreach may be done via mail or electronically 
(based on the Part D enrollee's preferred and authorized communication 
methods) and must include a Medicare Prescription Payment Plan election 
request form. The outreach must also include additional information 
about the Medicare Prescription Payment Plan, which may be fulfilled by 
including the CMS-developed fact sheet.
    In the proposed rule, we proposed to codify at paragraph 
(e)(4)(i)(A) of Sec.  423.137 that if Part D plan sponsors develop and 
use alternative informational materials in lieu of the CMS-developed 
fact sheet to satisfy this requirement, they must ensure that these 
alternative materials accurately convey program information and are 
compliant with existing Part D requirements specified at 42 CFR part 
423, subpart V, and in the Medicare Communications and Marketing 
Guidelines (MCMG). Additionally, the initial notice may be provided via 
telephone, so long as the standardized ``Medicare Prescription Payment 
Plan Likely to Benefit Notice'' and additional information are sent 
within 3 calendar days of the telephone notification.
    As discussed in the proposed rule, Part D plan sponsors should be 
aware that potential changes to a Part D enrollee's clinical condition, 
medication status, or cost sharing (for example, discontinuation of 
therapy or addition of supplemental payers) could affect the likelihood 
that a Part D enrollee may benefit from the Medicare Prescription 
Payment Plan and should counsel enrollees about their participation in 
the program accordingly. There are scenarios in which a Part D enrollee 
is less likely to benefit, and therefore, should not be notified that 
they are likely to benefit from the program. In the proposed rule, we 
proposed to codify at paragraph (e)(5) the targeted outreach 
exclusions.
    As noted in the proposed rule, we plan to revisit these targeted 
outreach requirements in future rulemaking, as CMS gains program 
experience and can evaluate program data and operations. In general, we 
expect to maintain the same overall framework for targeted outreach. In 
the proposed rule, we outlined an approach where CMS would assess the 
targeted outreach requirements for the POS notification threshold and 
prior to plan year criteria on an annual basis and make modifications, 
if needed, based on review and analysis of Medicare Prescription 
Payment Plan data and other Medicare data. Although CMS is not 
codifying an approach to modifying targeted outreach criteria for 
future years of the program, we solicited public comments on the 
approach and will use feedback from interested parties to support 
future policy development.
    Comment: Several commenters expressed support for CMS's intent to 
evaluate its targeted outreach framework and the likely to benefit 
thresholds for future years based on program experience. Specifically, 
a few commenters recommended that CMS use 2025 as an evaluation year to 
assess the Medicare Prescription Payment Plan's current operations, 
including the criteria for providing the ``Medicare Prescription 
Payment Plan Likely to Benefit Notice.'' Several commenters expressed 
support for CMS's proposal to maintain the current framework for 
targeted outreach to enrollees that are likely to benefit, including 
those who reached the $2,000 threshold by September of the previous 
plan year. A commenter stated that the proposal should help to minimize 
pharmacies' administrative burdens.
    Response: CMS appreciates the commenters' support and feedback. As 
outlined in the proposed rule, CMS plans to revisit these requirements 
in future rulemaking, after gaining program experience and evaluating 
program data and operations.
    Comment: A few commenters recommended that CMS reevaluate the 
identification criteria for likely to benefit to exclude LIS members, 
dually eligible individuals, or fully integrated dual eligible special 
needs plan (FIDE SNP) and highly integrated dual eligible special needs 
plan (HIDE SNP) members who already have limited cost-sharing 
responsibilities. A commenter recommended CMS narrow the scope of the 
program and relieve administrative burden on Part D plan sponsors by 
setting a higher threshold. The commenter stated that as currently 
implemented, any member with any amount of cost-sharing may elect into 
the program. Another commenter recommended CMS adopt a lower threshold 
for determining which patients will likely benefit from participation 
in the program. The commenter stated that the pharmacy POS notification 
threshold is too high and should take into account the total cost of 
all prescriptions a patient collects at the pharmacy that day and their 
OOP costs to date.
    Response: CMS thanks the commenters for their feedback. Under 
section 1860D-2(b)(2)(E)(i) of the Act, Part D plan sponsors must 
provide the option to opt into the Medicare Prescription Payment Plan 
to all Part D enrollees, including enrollees who are eligible for LIS. 
As discussed in the proposed rule, individuals with low, stable drug 
costs (such as LIS enrollees) are not likely to benefit from the 
program. Therefore, Part D plan sponsors are encouraged to provide 
support tailored to beneficiaries' unique situations and clearly 
communicate to enrollees when it appears that they are less likely to 
benefit from the program (for example, enrollees with low-to-moderate 
recurring OOP drug costs). Additionally, as discussed in the proposed 
rule, CMS has established requirements for Part D plan sponsors to 
provide information on the LIS program as part of their Medicare 
Prescription Payment Plan materials, including in the billing 
statement, notice of election approval, and on their websites. For the 
pharmacy POS notification, CMS chose a single prescription drug cost 
POS threshold of $600 because this approach strikes the best balance 
between identifying Part D enrollees with a very high likelihood (~98 
percent) of benefiting from the Medicare Prescription Payment Plan, 
while reducing the risk of identifying Part D enrollees for whom the 
program may not be as helpful.\17\
---------------------------------------------------------------------------

    \17\ In the final part one guidance, CMS summarized key findings 
from an analysis of POS thresholds ranging from $400 to $1,000. The 
proportion of identified enrollees who would benefit from the 
program ranged from 90 percent to greater than 99 percent.

    Comment: A few commenters recommended that CMS assess the efficacy 
of the targeted outreach criteria by investigating and publishing data 
on OOP costs of those enrollees who are likely to benefit and who elect 
into the program and of those enrollees who were notified that they 
were likely to benefit but did not elect into the program.
    Response: CMS appreciates the commenters' suggestions. As stated in 
the proposed rule, CMS requires Part D plan sponsors to report 
information related to the Medicare Prescription Payment Plan on 
prescription drug event (PDE) records and through reporting 
requirements at the beneficiary level through the MARx system and 
contract-PBP levels through the Health Plan Management System (HPMS). 
CMS will use these data to assess any potential revisions to the POS 
notification threshold in future years and will consider opportunities 
for publicly sharing the data.
    Comment: A commenter recommended that CMS conduct broader outreach 
to beneficiaries beyond the targeted outreach notification 
requirements. The commenter stated that broad outreach is important for 
many patients who may not fall into the likely to benefit parameters 
but could still see significant positive impacts from the program.
    Response: CMS thanks the commenter for their feedback. CMS agrees 
that educating beneficiaries about the program is important for its 
success. In advance of the implementation of the program on January 1, 
2025, CMS developed new educational resources and updated existing Part 
D materials, such as the ANOC, EOC, and Explanation of Benefits (EOB), 
to inform Part D enrollees about the program. CMS's education and 
outreach efforts discussed in the proposed rule and this final rule are 
not comprehensive of the various activities CMS is undertaking to 
educate Part D enrollees and other stakeholders about the program. 
Supporting broad awareness of the Medicare Prescription Payment Plan 
is, however, a shared responsibility between CMS and Part D sponsors. 
To ensure all prospective and current Part D enrollees are aware of the 
program, CMS has also established general Part D plan sponsor outreach 
and education requirements, which are discussed in further detail in 
the proposed rule and this final rule. After considering the comments 
we received and for the reasons outlined in the proposed rule and our 
responses to comments, we are finalizing our proposed provisions at 
Sec.  423.137(e) without modification.
e. Termination of Election, Reinstatement, and Preclusion
    Section 1860D-2(b)(2)(E)(v)(IV)(aa) of the Act requires a Part D 
plan sponsor to terminate an enrollee's Medicare Prescription Payment 
Plan participation if that enrollee fails to pay their monthly billed 
amount. In addition, under section 1860D-2(b)(2)(E)(v)(IV)(bb) of the 
Act, Part D sponsors may preclude an enrollee from opting into the 
Medicare Prescription Payment Plan in a subsequent year if the enrollee 
fails to pay the amount billed for a month as required under the 
program.
    We proposed standards for termination of election, reinstatement, 
and preclusion consistent with the statutory requirements. CMS 
established procedures for voluntary termination of election, under 
which Part D plan sponsors are required to have a process to allow a 
participant who has opted into the Medicare Prescription Payment Plan 
to opt out during the plan year. For 2025, we required Part D plan 
sponsors to process the participant's voluntary termination request and 
send the individual a notification confirming the termination within 10 
calendar days of receipt of the request but did not specify the 
effective date of termination. For 2026 and subsequent years, we 
proposed to maintain the requirement for Part D plan sponsors to send 
the notice of voluntary termination within 10 calendar days of receipt 
but require that the effective date of termination must be within 24 
hours of receipt of the voluntary termination request. We solicited 
public comment on this proposal.
    When a participant opts out of the Medicare Prescription Payment 
Plan, a Part D plan sponsor must provide the individual with a notice 
of voluntary termination after the individual notifies the Part D plan 
sponsor that they intend to opt out under the Part D plan sponsor's 
established process. At Sec.  423.137(f)(2)(i)(A)(2)(ii) of the 
proposed rule, we outlined required contents for the notice of 
voluntary termination. As discussed in the proposed rule, a Part D plan 
sponsor must offer the enrollee terminating their program participation 
the option to repay the full outstanding amount in a lump sum but is 
prohibited from requiring full immediate repayment from a participant. 
For 2026 and subsequent years, we proposed to codify the voluntary 
termination process and notice requirements at Sec.  423.137(f)(2)(i) 
and to add the voluntary termination notice as a required material and 
content for Part D plan sponsors at Sec.  423.2267(e)(50).
    We also proposed standards for involuntary termination, including 
requirements for the provision of a grace period of at least two months 
when an individual has failed to pay the billed amount by the payment 
due date and requirements for reinstatement. If an individual fails to 
pay the billed amount within 15 calendar days of the payment due date, 
the Part D plan sponsor must send the individual an initial notice of 
failure to pay. The required contents of the notice of failure to pay 
are detailed in the proposed rule and at Sec.  
423.137(f)(2)(ii)(C)(2)(i). If the individual fails to pay the amount 
due by the end of the grace period, the Part D plan sponsor must send 
the individual an involuntary termination notice explaining that the 
individual has been terminated from the Medicare Prescription Payment 
Plan. We proposed that the involuntary termination notice must be sent 
within 3 business days following the last day of the end of the grace 
period and must include the contents detailed in the proposed rule and 
at Sec.  423.137(f)(2)(ii)(D)(2). For 2026 and subsequent years, we 
proposed to codify these notice requirement standards at Sec.  
423.137(f)(2)(ii) and to add the notice of failure to pay and notice of 
involuntary termination as required model materials and content for 
Part D plan sponsors at Sec.  423.2267(e)(48) and (49). For the grace 
period, we proposed to make certain modifications to the timing 
requirements for the grace period and initial notice of nonpayment 
established in the final part one guidance. Specifically, for 2025, we 
required that the grace period must begin on the first day of the month 
for which the balance is unpaid or the first day of the month following 
the date on which the payment is requested, whichever is later. For 
2026 and subsequent years, we proposed to change the date on which the 
grace period must begin to the first day of the month following the 
date on which the initial notice is sent. As discussed in the proposed 
rule, we believe this would simplify the timing requirements for the 
notice of nonpayment and the required grace period. We solicited 
comment on the proposed change.
    We proposed that if a participant fails to pay their monthly billed 
amount with fewer than two full calendar months remaining in the 
calendar year, the grace period must carry over into the next calendar 
year. If the program

[[Page 15816]]

participant is within their grace period from the prior year, the Part 
D plan sponsor must allow the participant to opt into the program for 
the next year, but if the participant fails to pay the amount due from 
the prior year during the required grace period, the Part D plan 
sponsor may terminate the individual's participation in the program in 
the new year.
    A participant must be allowed to pay the overdue balance in full 
during the grace period to remain in the program. Additionally, Part D 
plan sponsors must reinstate an individual who has been terminated from 
the Medicare Prescription Payment Plan within a reasonable timeframe if 
the individual demonstrates good cause for failure to pay the program 
billed amount within the grace period and pays all overdue amounts 
billed. As discussed in the proposed rule, CMS proposed to adopt the 
same meaning of ``good cause'' outlined in section 60.2.4 of the 
Medicare Prescription Drug Benefit Manual, Chapter 3--Eligibility, 
Enrollment and Disenrollment that applies to reinstatements when an 
enrollee fails to pay their Part D premiums. A Part D plan sponsor may 
reinstate an individual who has been terminated from the Medicare 
Prescription Payment Plan and pays all overdue amounts billed in full, 
at the sponsor's discretion and within a reasonable timeframe, even if 
the individual does not demonstrate good cause. For 2026 and subsequent 
years, we proposed to codify these grace period and reinstatement 
requirements at Sec.  423.137(f)(3).
    In the proposed rule, we clarified that, consistent with the 
statute, a Part D plan sponsor may only preclude an individual from 
participating in the Medicare Prescription Payment Plan in a subsequent 
year if the individual owes an overdue balance to that plan sponsor. If 
an individual enrolls in a Part D plan offered by a different Part D 
plan sponsor than the Part D plan sponsor to which the individual owes 
an overdue balance, that individual cannot be precluded from opting 
into the Medicare Prescription Payment Plan in a subsequent year by 
that different Part D plan sponsor. We also stated that preclusion may 
extend beyond the immediate subsequent plan year if a Part D enrollee 
remains in a plan offered by the same Part D plan sponsor and continues 
to owe an overdue balance. For 2026 and subsequent years, we proposed 
to codify requirements related to preclusion of election in a 
subsequent plan year at Sec.  423.137(f)(4).
    We proposed to prohibit Part D enrollment penalties for failure to 
pay a Medicare Prescription Payment Plan amount billed. Additionally, 
we outlined that a Part D plan sponsor is prohibited from disenrolling 
a Part D enrollee from a Part D plan or declining future enrollment 
into a Part D plan for failure to pay any amount billed under the 
Medicare Prescription Payment Plan. We also proposed that if a 
participant in the Medicare Prescription Payment Plan is disenrolled 
voluntarily or involuntarily from their Part D plan under the 
provisions at 42 CFR 423.44(b), the participant is also terminated from 
the Medicare Prescription Payment Plan in that plan. For 2026 and 
subsequent years, we proposed to codify these requirements at Sec.  
423.137(f)(5) and (6).
    Comment: Several commenters expressed support for CMS's proposal to 
clearly identify the grace period start date and simplify the grace 
period timing requirements by changing the start of the grace period to 
the first day of the month following the issuance of the initial 
failure to pay notice. A commenter stated that the change will provide 
a better member experience and simplify plan sponsor operations and 
management of the program. However, a few commenters expressed 
opposition to the proposal, noting that it will extend the grace period 
by up to a month from the initial claim in some cases. The commenters 
expressed concern that this will allow for potential program abuse by 
extending the time to accumulate unpaid claims before Part D plan 
sponsors can end beneficiaries' participation in the program. Another 
commenter stated that the grace period should begin on the due date of 
missed payment because this is a date that is known by all parties.
    A commenter expressed opposition to the proposed grace period 
length and recommended CMS shorten the minimum grace period to reduce 
potential risk for non-payments.
    Response: CMS thanks commenters for their feedback. CMS will 
continue to engage stakeholders on issues related to implementation and 
program integrity. While CMS appreciates the recommendation to have the 
grace period begin on the due date of the missed payment, we do not 
agree with the suggestion. Requiring the grace period to begin on the 
first day of the month following the date on which the initial notice 
is sent simplifies the program requirements, reducing the burden on 
Part D plan sponsors.
    Comment: A few commenters recommended that CMS add information 
about retroactive LIS eligibility to the notice of voluntary 
termination, notice of failure to pay, involuntary termination notice, 
and billing statement in order to provide timely information about 
accessing LIS assistance. A commenter recommended that the involuntary 
and voluntary termination notices for the program include reminders to 
beneficiaries to continue to pay monthly Part D premiums to maintain 
drug coverage.
    Response: CMS thanks commenters for their feedback. As discussed in 
the proposed rule, CMS has established requirements for Part D plan 
sponsors to provide information on the LIS program as part of their 
Medicare Prescription Payment Plan materials. Part D plan sponsors are 
required to include general information about the LIS program, 
including how LIS enrollment for eligible individuals is likely to be 
more advantageous than participation in the Medicare Prescription 
Payment Plan, on their websites. In addition, the notice of election 
approval must include an overview of other Medicare programs that can 
help lower costs, including the LIS Program (also known as Extra Help), 
the Medicare Savings Program, the State Pharmaceutical Assistance 
Program, and the Manufacturer's Pharmaceutical Assistance Program, and 
how to learn more about these programs. Additionally, CMS notes that 
the involuntary termination and voluntary termination notices are both 
required to include a statement clarifying that the notice only applies 
to participation in the Medicare Prescription Payment Plan.
    Comment: Several commenters expressed concern about the proposed 
requirement that voluntary terminations take effect within 24 hours. 
They recommended that CMS extend the timeframe for the effective date 
of termination to 3 business days or 72 hours from the time the plan 
sponsor receives the voluntary termination request to accommodate the 
need for greater flexibility in processing times in some cases, 
including weekends and holidays. A commenter stated that changing the 
requirement to 3 business days would provide plan sponsors with 
adequate time to process the request within the allotted time, provide 
uniformity across the industry for the program, and simplify data 
submission processes. A few commenters expressed support for the 24-
hour timeframe for the effective date of termination. A commenter 
stated that CMS has not specified the termination events that fall 
within the 24-hour requirement. The commenter recommended that CMS 
provide guidance on the effective program termination date for all plan 
disenrollment events.

[[Page 15817]]

    Response: CMS thanks commenters for their feedback. While the 24-
hour requirement aligns with the required timeframe for processing 
election requests during the plan year, CMS agrees that extending the 
timeframe reduces burden on Part D plan sponsors while still ensuring a 
timely response to opt out requests during the plan year. Consequently, 
we are modifying our proposal of 24 hours and finalizing the 
requirement as 3 calendar days. We are not adopting the recommendation 
of 3 business days as suggested by a few commenters in order to 
simplify program requirements by making all timeframe requirements in 
calendar days. All scenarios in which the Part D enrollee requests to 
voluntarily terminate their participation in the program must be 
processed within the 3-calendar day window. CMS is not providing 
guidance on the effective date for Part D plan sponsors to process 
involuntary terminations at this time but continues to welcome 
stakeholder feedback on the issue.
    Comment: A commenter stated that patients and pharmacies are 
concerned that a plan would attempt to collect the unpaid balance at 
the pharmacy counter after the required 2-month grace period. The 
commenter recommended that CMS make it easy for beneficiaries and 
pharmacists to file a complaint with CMS if they suspect incorrect 
cost-sharing calculations and wrongful termination from the program. 
Another commenter expressed support for proposals to protect enrollees 
from improper termination.
    Response: CMS appreciates the commenters' feedback and recognizes 
concerns about protecting beneficiaries from wrongful termination. As 
described in the proposed rule, Part D sponsors must use their existing 
coverage determination, appeals, and grievance procedures for the 
Medicare Prescription Payment Plan to ensure that Part D enrollees have 
the ability to contest copay amounts and any adverse decisions related 
to participation in the Medicare Prescription Payment Plan. 
Additionally, CMS tracks plan grievances and beneficiary complaints 
entered in the Medicare Complaints Tracking Module (CTM) to assess 
compliance with all Medicare Prescription Payment Plan requirements and 
ensure program integrity.
    Comment: A commenter recommended that the calculation in the first 
paragraph of the model notice of failure to pay be aligned with the 
changes in the final rule and provide the updated model as soon as 
possible.
    Response: CMS thanks the commenter for their suggestion. CMS issued 
model materials that Part D enrollees can use to fulfill the failure to 
pay, involuntary termination, and voluntary termination notice 
requirements through the Medicare Advantage and Prescription Drug 
Programs: Part C and Part D Medicare Prescription Payment Plan Model 
Documents (CMS-10882; OMB 0938-1475) ICR package. We will make any 
necessary changes to align the existing model materials with this final 
rule through the standard non-rule PRA process, which includes the 
publication of 60- and 30-day Federal Register notices.
    Comment: A commenter stated that in section 80.3 of the final part 
one guidance, CMS states that ``preclusion is only permitted in plans 
that are offered by the same parent organization.'' The commenter 
recommended that CMS aligns the language in the proposed rule with the 
final part one guidance by replacing ``Part D sponsor'' with ``parent 
organization'' to provide additional clarity and to ensure preclusion 
is applied consistently by Part D plan sponsors. Another commenter 
stated that the proposal for Sec.  423.137(f)(4) may be partially 
unenforceable. The commenter observed that section 1860D-
2(b)(2)(E)(v)(IV) of the Act states that ``if an enrollee fails to pay 
the amount billed for a month as required under this subparagraph [. . 
.] the PDP sponsor or MA organization may preclude the enrollee from 
making an elec
