St. Augustine is located in St. Johns County, between Jacksonville to the north and Palm Coast to the south. Medicare Advantage and Part D plan availability is determined by county and by the residential ZIP code used for enrollment, so the plans available to a St. Augustine resident may differ from those available in other parts of Florida.

HCA Florida Flagler Hospital is the primary acute care hospital serving St. Augustine and St. Johns County. If you are comparing Medicare Advantage plans, confirming that your preferred hospital and specialists participate in a plan's network is an important step before enrolling.

St. Johns County is one of the fastest-growing counties in Florida. If you are comparing Medicare Supplement coverage, the plan letter and standardized benefits are the same regardless of which carrier you choose — but premiums can vary meaningfully from one company to another for the same plan.

St. Augustine is located in St. Johns County (FIPS 12109). The county relationship gives context for Medicare Advantage and Part D service areas, while a residential address is used to confirm an individual’s available options.

Residents comparing Medicare can benefit from first deciding whether Original Medicare or Medicare Advantage better fits their preferred way to receive care.

If you are approaching Medicare eligibility, your Initial Enrollment Period begins three months before the month you turn 65 and extends three months after. This is generally the most favorable time to enroll in a Medicare Supplement plan because federal guaranteed-issue rights apply — insurers cannot use medical underwriting to deny coverage or charge higher premiums based on your health history.

St. Augustine residents turning 65 have two main paths: Original Medicare (Parts A and B) with a Medicare Supplement plan and a standalone Part D drug plan, or Medicare Advantage (Part C) through a private insurer. The right path depends on your doctors, prescriptions, expected use of care, and how you want to manage out-of-pocket costs.

Medicare Supplement insurance — also called Medigap — works alongside Original Medicare to help cover certain out-of-pocket costs such as deductibles, coinsurance, and copayments. Medigap plans are standardized by the federal government: a Plan G from one company covers the same core benefits as a Plan G from any other company. What differs between carriers is the premium, the company's financial strength, and its history of rate increases.

Plan G is one of the most comprehensive Medigap options available to people newly eligible for Medicare on or after January 1, 2020. Plan N offers a lower premium in exchange for copays on some office and emergency room visits. Because Medigap benefits are standardized, comparing premiums across carriers is one of the most practical steps a St. Augustine resident can take. An independent broker can pull real-time rates from multiple carriers — at no cost to you.

The Initial Enrollment Period is an important time for people becoming eligible for Medicare. Medicare Advantage and Part D plans can also be reviewed during the Annual Enrollment Period, October 15 through December 7.

Florida does not currently provide a general annual Medigap Birthday Rule. Outside a Medigap Open Enrollment Period or another applicable guaranteed-issue right, changing Medicare Supplement coverage may require medical underwriting. An independent broker can explain the comparison process for a St. Augustine resident and help identify questions to ask.
