Medicare Part D Disclosures due by Feb. 29, 2024 for Calendar Year Plans

Each year, group health plan sponsors are required to complete an online disclosure form with the Centers for Medicare & Medicaid Services (CMS), indicating whether the plan’s prescription drug coverage is creditable or non-creditable. This disclosure requirement applies when an employer-sponsored group health plan provides prescription drug coverage to individuals who are eligible for coverage under Medicare Part D. Employers should confirm whether their health plans’ prescription drug coverage is creditable or non-creditable and prepare to send their Medicare Part D disclosure notices before Oct. 15, 2023. To make the process easier, employers often include Medicare Part D notices in open enrollment packets they send out prior to Oct. 15.

CMS Disclosure Deadline

The plan sponsor must complete the online disclosure within 60 days after the beginning of the plan year. For calendar year health plans, the deadline for the annual online disclosure is Feb. 29, 2024 (since 2024 is a leap year).

In addition to the annual disclosure requirement, the disclosure to CMS must be made whenever any change occurs that affects whether the coverage is creditable. More specifically, within 30 days after any change in the plan’s creditable coverage status or after the termination of a plan’s prescription drug coverage.

Online Disclosure Method

Plan sponsors are required to use the online disclosure form on the CMS creditable coverage website. This is the sole method for compliance with the disclosure requirement unless the entity does not have internet access.

The disclosure form lists the required data fields that must be completed in order to generate the disclosure notice to CMS, such as types of coverage, number of options offered, creditable coverage status, period covered by the disclosure notice, number of Part D-eligible individuals covered, date the creditable coverage disclosure notice is provided to Part D-eligible individuals and change in creditable coverage status.

CMS has also provided guidance and instructions on how to complete the form.

Action Steps

To determine whether the CMS reporting requirement applies, employers should verify whether their group health plans cover any Medicare-eligible individuals (including active employees, disabled employees, COBRA participants, retirees, and their covered spouses and dependents) at the start of each plan year.

Employers that are required to report to CMS should work with their advisors to determine whether their prescription drug coverage is creditable or non-creditable. They should also visit CMS’ creditable coverage website, which includes links to the online disclosure form and related instructions.
