Statewide, 56.7% 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 rights, which in Ohio follow the federal rule at 65 (one guaranteed six-month window, no birthday rule, no year-round switching) and, unlike some states, add no under-65 guaranteed-issue right, so timing at 65 matters even more. About 9.5% of Ohio seniors live below the poverty line, the group most likely to qualify for unclaimed help: Extra Help and the Medicare Savings Programs.
