The Polk County medicare supplement market
Polk County posts one of the highest Medicare Advantage adoption rates in Florida — roughly 69% of its 182,250 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. Humana Gold Plus H1036 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 39 Medicare Advantage plans are available in Polk County, so a side-by-side comparison genuinely matters. Medicare Advantage enrollment figures reflect the latest CMS data (May 2026).
