    Medicare Part D: Plan Sponsors Must Complete Disclosure to CMS by March 1


    Online Disclosure to CMS

    In addition to the annual requirement to provide all Medicare-eligible plan participants with notices of creditable and non-creditable coverage, welfare plan sponsors must also complete the Online Disclosure to CMS Form to report the creditable coverage status of their prescription drug plan.

    The Disclosure should be completed annually no later than 60 days from the beginning of a plan year (contract year, renewal year), within 30 days after termination of a prescription drug plan, or within 30 days after any change in creditable coverage status. This requirement does not pertain to the Medicare beneficiaries for whom entities are receiving the Retiree Drug Subsidy (RDS).

    For calendar year plans, the deadline is (end of day) March 1, 2024.  For non-calendar year plans, the deadline is 60 days past the beginning day of the Plan Year.

    The CMS online tool is the only method allowed for completing the required disclosure. Click on the link, then follow the prompts to respond to a series of questions regarding the plan. The link is the same regardless of whether the employer’s plan provides creditable or non-creditable coverage. The entire process usually takes only 5 or 10 minutes to complete.

    The employer will need to gather the following information in order to complete the online disclosure to CMS:

    • Information about the plan sponsor (employer): Name, address, phone number, and federal Employer Identification Number (EIN).
    • Number of prescription drug options offered (e.g., if employer offers two plan options with different benefit levels, the number is “2”).
    • Creditable/Non-creditable Offer: Indicate whether all options are creditable or non-creditable or whether some are creditable and others are non-creditable.
    • Plan year beginning and ending dates.
    • Estimated number of plan participants eligible for Medicare (and how many are participants in the employer’s retiree health plan, if any).
    • Date that the plan’s Notice of Creditable (or Non-creditable) Coverage was provided to participants.
    • Name, title, and email address of the employer’s authorized individual completing the disclosure.


    Please note that CMS is no longer providing employers with emailed confirmations of submission; therefore, we recommend saving a screenshot of the confirmation screen and saving it in an accessible location on your local or cloud storage. You may also wish to print (and retain for your records) the confirmation.
