guaranteed renewable

Medigap plans are guaranteed renewable, with the exception of some policies purchased before 1992 in some states.¹ And Medigap benefits are standardized, so the policy will renew with the same benefits from one year to the next (except for the deductibles and out-of-pocket limits that apply to some Medigap plans, as those change each year).²

Medicare Advantage and Medicare Part D plans are also guaranteed renewable, but benefits on those plans can change significantly from one year to the next, so although your plan will renew if you don’t make changes during open enrollment (and assuming you continue to pay your premiums), your coverage might be very different in the coming year.
