The Sumter County medicare supplement market

About 57% of Sumter County's 88,772 Medicare beneficiaries are in Medicare Advantage — right around the national norm — so you'll find a genuine mix of competitive MA plans and Medigap options here rather than a one-sided market. The county skews older than the Florida average (59% are 65 or older), which means heavy carrier competition and meaningful plan turnover each Annual Enrollment Period — a yearly review almost always pays off. UnitedHealthcare AARP Medicare Advantage The Villages currently leads the county by enrollment, but the lowest total-cost plan for your specific drugs and doctors is often a smaller carrier — which is why we run all of them side by side instead of pushing the biggest name. Right now roughly 37 Medicare Advantage plans are available in Sumter County, so a side-by-side comparison genuinely matters. Medicare Advantage enrollment figures reflect the latest CMS data (May 2026).
