Statewide, 62.8% of beneficiaries chose Medicare Advantage in 2025. Counties above that line see more prior authorizations and more denials worth appealing; counties below it lean on Medigap timing, which in Michigan follows the federal rules with no birthday rule and no annual reset: the one guaranteed six-month window opens at 65, and Michigan requires only insurers that also sell major medical coverage to offer under-65 disability Medigap (Plans A and G), so getting the timing right the first time is what counts. About 9.3% of Michigan seniors live below the poverty line, the group most likely to qualify for unclaimed help: Extra Help and the Medicare Savings Programs, which MDHHS runs with an income and asset test.
