Medicare Part D – Prescription Coverage (2025) – California Large Group

Share this Content

If you offer prescription drug coverage through a group health plan, Medicare regulations require you to inform CMS and Medicare-eligble employees (sometimes retirees) annually at case install or renewal within 60 days window whether their employer-sponsored coverage is considered “creditable” under Medicare guidelines.

Coverage is considered creditable if it meets or exceeds the value of the standard Medicare Part D prescription drug plan.

It’s important to note that pharmacy plans within a high-deductible health plan (HSA-compatible) can be either creditable or non-creditable, depending on whether Medicare is the primary or secondary payer.

This guide highlights Medical plans that are classified as non-creditable. Any plans not listed in this guide are considered creditable.
