At roughly 39% MA penetration, most of St. Johns County's 79,462 Medicare beneficiaries stay on Original Medicare, frequently paired with a Medigap policy. That pattern usually signals retirees here prize provider choice and predictable out-of-pocket costs over the lower premiums of MA. 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.
