The Hamilton County medicare supplement market
About 59% of Hamilton County's 3,302 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. Humana Full Access Giveback H5216-393 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 9 Medicare Advantage plans are available in Hamilton County, so a side-by-side comparison genuinely matters. Medicare Advantage enrollment figures reflect the latest CMS data (May 2026).

What makes Hamilton County different: Hamilton County has had no hospital of its own since the former Hamilton County Memorial Hospital sold its operating assets to Columbia/HCA in 1994, so its roughly 3,300 Medicare beneficiaries rely on out-of-county facilities -- the full-service HCA Florida Lake City Hospital in Columbia County and the critical-access Madison County Memorial Hospital, plus an ER-only HCA Florida Suwannee Emergency in Live Oak (the former Shands hospital, converted to emergency-only in 2020). Its senior share is unusually low for Florida because the population includes the ~1,177-capacity Hamilton Correctional Institution in Jasper and a phosphate-mining workforce (Nutrien's White Springs operation employs roughly 600+ near White Springs), keeping the median age at about 41.
