Statewide, 44.1% 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, where Mississippi has no birthday rule: after the six-month open enrollment, switching supplements usually means health questions unless a federal guaranteed issue right applies. About 14.3% of Mississippi seniors live below the poverty line, the group most likely to qualify for unclaimed help: Extra Help and Mississippi's Medicare Savings Programs, which the Division of Medicaid decides on income alone, with no resource test.
