What if you live in a county it leaves?
Its 2026 members in the 4 counties listed below cannot stay in it for 2027; each county page lists the 2027 plans sold there.
- Your coverage
- This plan ends for you on December 31, 2026, because it is no longer sold where you live.
- October 15 to December 7, 2026
- Open enrollment: join another Medicare Advantage plan, or Original Medicare with a drug plan. Coverage starts January 1, 2027.
- December 8, 2026 to the end of February 2027
- A special enrollment period because the plan is leaving: you can still join a plan, but coverage starts the first day of the month after you join, so choose by December 31 to have no gap.
- If you do nothing
- You are enrolled in Original Medicare when the plan ends, without a drug plan unless you join one (with Extra Help or full Medicaid, Medicare enrolls you in one).
- Without a drug plan
- Going 63 days or more in a row without drug coverage can mean a late enrollment penalty if you join a drug plan later; joining by the end of February keeps a January and February gap under 63 days, waiting longer does not.
- If you choose Original Medicare
- You have a guaranteed right to buy Medigap Plan A, B, C, D, F, G, K or L sold in your state by any insurance company; if you were new to Medicare on or after January 1, 2020, Plans D and G take the place of C and F. Apply from 60 days before to 63 days after the plan ends; the policy starts once your Medicare Advantage coverage ends. Other Medigap plans are not covered by this right.
