Statewide, 50.4% 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 Indiana follow the federal rule at 65 (one guaranteed six-month window, no birthday rule, no year-round switching) and, as of January 1, 2025 under Senate Enrolled Act 215, add a guaranteed-issue right for beneficiaries under 65 who qualify through disability or ESRD. About 8.6% of Indiana seniors live below the poverty line, the group most likely to qualify for unclaimed help: Extra Help and the Medicare Savings Programs.
