Ending here: the plan isn't offered in the county in 2027, and the company can't move members into another plan under the same contract there. Members need to pick a new plan unless their letter says they will be moved. If they do nothing, they will have Original Medicare. May be moved: the plan ended everywhere, but the same contract still has other plans in the county. Some companies move members into one of those plans. Many don't. The letter from the plan will say. Everyone in these plans keeps Medicare.

If you're in one of these plans, you can pick a new plan from October 15 to December 7, 2026. If your plan is ending, you also have until February 28, 2027. That extra time doesn't apply if your plan is being combined into another plan. Check your plan to see what happens if you do nothing.
These numbers come from CMS's plan files. If you're in one of these plans, confirm with your Annual Notice of Change or the letter from your plan.
