Not offered: CMS's 2027 plan list and plan crosswalk show the plan isn't offered in the county (for drug plans, the state) in 2027 and its members aren't moved to another plan there. Members need to pick a new plan, unless their plan's letter offers another option. If they do nothing, Medicare Advantage and Cost plan members will have Original Medicare. Members of any plan that covered drugs will have no Medicare drug coverage, unless they get Extra Help (outside U.S. territories, Medicare then puts them in a drug plan). Everyone in these plans keeps Medicare.

These numbers come from CMS's plan files. If you're in this plan, confirm with your Annual Notice of Change or the letter from your plan.
