Statewide, 54.2% 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 Pennsylvania follow the federal rule at 65 (one guaranteed six-month window, no birthday rule, no year-round switching) but add a strong under-65 guaranteed-issue right for disability and ESRD at age-65 premiums, so timing still matters. About 9.4% of Pennsylvania seniors live below the poverty line, the group most likely to qualify for unclaimed help: Extra Help, the Medicare Savings Programs, and Pennsylvania's own PACE and PACENET drug programs.
