Statewide, 53% 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 New York include year-round plan switching. About 13.3% of New York seniors live below the poverty line, the group most likely to qualify for unclaimed help: Extra Help, the Medicare Savings Programs, and EPIC.
