Where to find the list
We keep the company names and counties on one page built from CMS files, with each file cited: Medicare plans ending in 2027. It compares the CMS 2026 and 2027 Landscape files, the 2027 plan crosswalk and October 2026 enrollment data, and shows how many members are affected in each county.
Two kinds of changes are on that page:
- A company leaves a county. Six companies stop selling Medicare Advantage plans in some Oregon counties for 2027.
- A plan ends, but the company stays. Other companies end some plans while keeping others in the same area. Members of those plans also have to choose.
Statewide, CMS still lists 61 Medicare Advantage plans open to everyone from 14 companies for 2027, but choices depend on your county. Grant, Harney, Lake, Umatilla and Union counties have no Medicare Advantage plan open to everyone in 2026 or 2027, and Curry County has only a special needs plan. Check your county.
How to tell if you're affected
| Letter you got | What it means |
|---|---|
| Non-renewal notice | Your plan ends December 31, 2026. You need new coverage. |
| Annual Notice of Change | Your plan continues for 2027 with changes. Review it. |
| Letter moving you to another plan from the same company | Your plan is replaced. Check that the new one covers your doctors and drugs. |
Your deadlines if your plan ends
- By December 31, 2026: choose a new plan so it starts January 1 with no gap.
- Through February 28, 2027: your special enrollment period to join another plan.
- Through March 4, 2027: your right to buy certain Medigap policies without health questions (63 days after your plan ends).
Step by step: what should I do if my plan is leaving. To compare plans from the companies they work with, you can request a call from a licensed insurance agent, or see plans for your ZIP code.

Frequently asked questions
How do I know if my plan is ending?
Your plan must send you a letter. A non-renewal notice means the plan ends December 31, 2026. An Annual Notice of Change means it continues with changes.
Is my Medigap policy affected?
No. These changes are to Medicare Advantage plans. A Medigap policy is guaranteed renewable as long as you pay the premium.
Will I lose Medicare if I do nothing?
No. If your Medicare Advantage plan ends and you don't choose another, you go back to Original Medicare on January 1, but without Part D drug coverage until you join a plan.
