US Medicare Advantage Exit Options Explained

A major insurer said targeted 2027 Medicare Advantage exits would affect ~600K members, while expecting a meaningful share to move into other company plans.
If a Medicare Advantage plan is not renewed, Medicare eligibility remains, and members who do not pick replacement coverage generally return to Original Medicare.
The main enrollment window runs from Early-Q4 to Mid-Q4, with changes generally starting Early-Q1; a separate special window then extends through Mid-Q1.
Switching to Original Medicare can unlock a protected Medigap window, starting 60 days before coverage ends and closing no more than 63 days after.
When comparing options, check doctors, hospitals, formularies, copays, deductibles, and worst-case yearly costs, because a $0 premium can hide much bigger tradeoffs.
Free, unbiased counseling is available through state assistance programs, and confirming choices with Medicare or a qualified adviser can help avoid coverage gaps.
