How to Get Medicare Part D Coming From Marketplace Coverage

To get Part D when transitioning from Marketplace coverage, first verify whether your Marketplace drug plan was confirmed creditable in writing. If it was creditable and is ending, you have a 63-day Special Enrollment Period to enroll in Part D without a penalty. If the coverage was not creditable, or if you are past 63 days since it ended, enroll in Part D as soon as possible — a permanent 1% per month penalty applies for each uncovered month after your Part D Initial Enrollment Period.

Frequently Asked Questions

Do I get a Part D enrollment period when I lose Marketplace coverage?
Yes — if your Marketplace drug coverage was creditable, losing it opens a 63-day Special Enrollment Period to enroll in Part D without a penalty. If the coverage was not creditable, you may already have a penalty accumulating.
How do I know if my Marketplace drug coverage was creditable?
Your Marketplace plan must provide a creditable coverage notice annually before October 15. Check that notice. If you do not have it, contact your plan. Without written confirmation, do not assume the coverage was creditable.
Can I get Part D if I am still on Marketplace coverage?
Generally, you can enroll in a Part D plan at your Part D IEP (the 7-month window around your 65th birthday) or during an SEP. If you have confirmed creditable Marketplace drug coverage, you may delay Part D without penalty — but verify the creditable status first.
