Compliance Reminder: Upcoming CMS Medicare Part D Disclosure Reporting Deadline

Employers sponsoring group health plans that provide prescription drug coverage to individuals eligible for Medicare Part D coverage^[1] must annually disclose to the Centers for Medicare and Medicaid Services (CMS) whether that coverage is considered creditable or non-creditable.

To be considered creditable, the plan’s drug coverage must be at least as generous as Medicare Part D prescription drug coverage. Click here for a Risk Strategies article with more information on determining the creditable coverage status of a plan’s prescription drug benefit.

This disclosure reporting requirement^[2] applies to self-funded, level-funded, and fully insured group health plans, and also applies whether the prescription drug coverage is primary or secondary to Medicare.

This annual disclosure must be provided to CMS within 60 days of the start of the plan year, which is typically March 1 (or February 29 for leap years).

For employers with calendar year group health plans (January 1, 2026 – December 31, 2026), the upcoming deadline to complete this disclosure reporting to CMS is March 1, 2026.

Employers must also complete disclosure reporting to CMS within 30 days following either:

a change in the creditable coverage status of the prescription drug coverage, or
the termination of the plan’s prescription drug coverage.

Online Disclosure to CMS

CMS's webpage on Creditable Coverage can be accessed here.

Online reporting is the sole method for compliance with the disclosure requirement, unless an employer sponsoring a group health plan does not have internet access.

CMS Disclosure Form Required Data Fields Include:

Details on the entity offering coverage, such as:
- Name of the employer sponsoring the benefit plan (not the insurance carrier or third-party administrator)
- Employer address and phone number
- Employer Federal Tax Identification Number (also known as EIN)
Practical Tip: For an entity with subsidiaries/divisions, one disclosure form can be submitted to CMS if the plan year is the same for all subsidiaries/divisions. If all subsidiaries/divisions of the entity are covered under the same type of coverage, use the parent company's EIN.
Type of coverage (choose from the applicable options)
Number of prescription drug options offered
Creditable coverage status of options offered by the entity
Period covered by the disclosure notice (plan year, which CMS defines as the beginning and ending date of the entity’s annual renewal or contract period)
Number of Part D-eligible individuals expected to be covered under the plan(s) as of the beginning date of the plan year.
Practical Tip: CMS guidance directs employers to estimate how many Part D-eligible individuals they expect to be covered as of the first day of the plan year, excluding any applicable Retiree Drug Subsidy participants. Employers should work with their plan vendors (including insurance carriers, third-party administrators, pharmacy benefits managers, etc.) to verify whether the prescription drug plans offered cover any Medicare-eligible individuals (including active, retired, disabled individuals, their dependents, or individuals on COBRA) at the start of each plan year.

Individuals who will not become eligible until sometime during the year should not be included for that year (they should be included in the notice for the next plan year).
Date of Notice of Creditable Coverage provided to Part D-eligible individuals
Change in creditable coverage status, if applicable (select "No" if not applicable)
Name, title, and email of the entity’s Authorized Individual (an "Authorized Individual" is the person completing the disclosure form that is either employed by the entity or contracted with the entity as an Authorized Individual to complete the disclosure on behalf of the entity).

Medicare Part D Creditable Coverage Notice

Please note that this annual disclosure reporting to CMS is different from the requirement to provide Part D-eligible individuals with a notice disclosing the creditable status of the plan’s prescription drug coverage by October 15 of each year (coinciding with the annual Medicare Part D enrollment period).

Employer Next Steps

Employers with calendar year plans are advised to take action now and complete the online disclosure reporting to CMS by the deadline of March 1, 2026.
