Medicare in St. Johns County: What You Need to Know
St. Johns County's rapid growth and proximity to Jacksonville's major medical centers creates unique Medicare planning considerations for local seniors.
St. Johns County: Florida's Fastest-Growing Medicare Market
St. Johns County is one of the fastest-growing counties in Florida — and its senior population is growing even faster. The county is home to St. Augustine (Florida's oldest city), Ponte Vedra Beach, Nocatee, and World Golf Village. Flagler Health+ (Flagler Hospital) is the anchor hospital, but the county's proximity to Jacksonville means many residents also use Baptist Health, UF Health, and Mayo Clinic for specialized care.
Medicare Advantage Networks in St. Johns County
Most major Medicare Advantage carriers offer plans in St. Johns County, including Humana, Florida Blue, UnitedHealthcare, Aetna, WellCare, and Devoted Health. Because many St. Johns County residents use hospitals in both St. Johns County (Flagler Health+) and Duval County (Baptist Health, UF Health, Mayo Clinic), it's critical that your plan covers facilities in both counties. William Gray specializes in verifying multi-county coverage for St. Johns County seniors.
Mayo Clinic and Medicare Advantage: A Critical Warning
Mayo Clinic Florida in Jacksonville is approximately 25 miles from St. Augustine — and many St. Johns County seniors want access to Mayo Clinic for complex conditions. However, Mayo Clinic has historically been selective about which Medicare Advantage plans it accepts. With Original Medicare and a Medigap plan, you have unrestricted access to Mayo Clinic. With Medicare Advantage, you must verify that your specific plan includes Mayo Clinic in-network before enrolling.
Flagler Health+ and Medicare
Flagler Health+ (formerly Flagler Hospital) is the dominant health system in St. Johns County. It accepts Original Medicare and participates in most major Medicare Advantage networks. Flagler Health+ has been expanding rapidly — adding urgent care locations, freestanding ERs, and the UF Health partnership in Nocatee. For most St. Johns County seniors, Flagler Health+ is their primary hospital, and verifying your plan's Flagler Health+ coverage is the most important step in plan selection.
Skilled Nursing Facilities and Medicare Part A in St. Johns County
St. Johns County has a growing number of skilled nursing facilities to serve its expanding senior population. After a qualifying 3-day hospital stay, Medicare Part A covers up to 100 days of skilled nursing care. Days 1–20 are fully covered; days 21–100 require a $209.50/day copay (2026). Medigap Plan G covers this copay. Medicare Advantage plans have varying SNF cost-sharing — verify your plan's SNF benefits before you need them.

Does Medicare cover Mayo Clinic in Jacksonville?
Original Medicare (Parts A and B) covers care at Mayo Clinic Florida. However, Medicare Advantage coverage at Mayo Clinic varies significantly by plan — Mayo Clinic has historically been selective about which Medicare Advantage plans it accepts.

William Gray offers free plan comparisons — call (386) 871-3858.
Are freestanding ERs in St. Johns County covered by Medicare?
Yes — freestanding ERs like Flagler Health+ ER Murabella are covered by Medicare Part B as hospital outpatient services. Your cost-sharing differs from a traditional hospital ER visit. With Original Medicare, you pay 20% coinsurance after the Part B deductible. With Medicare Advantage, verify your plan's outpatient ER cost-sharing.
