If your Medicare Advantage plan is ending or leaving your county
- Your plan must mail you a notice. Check that notice for your plan’s exact status.
- You can choose a new plan during Medicare’s Annual Enrollment Period, October 15 to December 7.
- Because your plan is ending or leaving your county, you also get a Special Enrollment Period, from December 8 through the last day of February.
- If you do not choose a plan, you return to Original Medicare on January 1. If you get Extra Help paying for prescriptions, Medicare places you in a Part D drug plan, and you can still choose a different plan. If you do not get Extra Help, you need to join a Part D drug plan yourself to keep drug coverage.
- You may also have a guaranteed right to buy certain Medicare Supplement (Medigap) policies.
If your Part D drug plan (PDP) is ending
- Your plan must mail you a notice. Check that notice for your plan’s exact status.
- You can choose a new drug plan during Medicare’s Annual Enrollment Period, October 15 to December 7, and you also get a Special Enrollment Period from December 8 through the last day of February.
- Your Original Medicare coverage for doctors and hospitals does not change. Only your drug plan is ending.
- If you get Extra Help paying for prescriptions, Medicare places you in another drug plan. If you do not get Extra Help and do not join another drug plan, your drug coverage ends when the plan ends. Going without drug coverage can lead to a late enrollment penalty later.
For all of your options, contact Medicare.gov or 1-800-MEDICARE.
