How Medicare Works

Medicare is federal health insurance with four parts: Part A (hospital), Part B (medical), Part C (Medicare Advantage. A private all-in-one alternative), and Part D (prescription drugs). Most people enroll at 65 and then choose either Original Medicare plus a supplement (Medigap) and Part D, or a Medicare Advantage plan. Availability and benefit structures vary by county in Florida, Alabama, Georgia, and North Carolina.

Medicare has four main parts-and choosing coverage can feel overwhelming. We explain how Original Medicare, Medicare Advantage, Medicare Supplement, and Part D fit together so you can review your options with confidence.
