Ending here: no plan is left under the same contract in the county; members need to pick a new plan, or they will have Original Medicare. May be moved: the same contract still has other plans in the county, and companies often move members into one of them automatically. CMS's plan crosswalk, expected in October, will say which. Everyone in these plans keeps Medicare.
