The Jefferson County medicare supplement market
Jefferson County posts one of the highest Medicare Advantage adoption rates in Florida — roughly 65% of its 4,223 beneficiaries chose an MA plan over Original Medicare. That level of uptake usually means carriers compete hard locally, so the extra benefits (dental, OTC allowance, transportation, gym) tend to be richer than the Florida average. The county skews older than the Florida average (25% are 65 or older), which means heavy carrier competition and meaningful plan turnover each Annual Enrollment Period — a yearly review almost always pays off. Capital Health Plan 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 13 Medicare Advantage plans are available in Jefferson County, so a side-by-side comparison genuinely matters. Medicare Advantage enrollment figures reflect the latest CMS data (May 2026).

What makes Jefferson County different: Jefferson County has no hospital within its borders and is a designated primary-care Health Professional Shortage Area, so its roughly 4,100 Medicare beneficiaries travel about 30 minutes west to Tallahassee (Leon County) for hospital care; about 17% of them (711) are dual-eligible for Medicaid, and the Tallahassee-based nonprofit Capital Health Plan HMO is the county's single largest Medicare Advantage plan.
