Understanding the Four Parts of Medicare, Plus Medigap, in Plain Language

The Shortest Possible Answer

Medicare is divided into Parts A and B (Original Medicare), Part C (Medicare Advantage), Part D (prescriptions), and Medigap (supplemental). Most people use a combination.

Part a - Hospital Insurance

Part A covers inpatient hospital stays, skilled nursing facility care, hospice, and some home health. If you or a spouse worked at least 10 years (40 quarters) and paid Medicare taxes, Part A has no premium.

Part B - Medical Insurance

Part B covers doctor visits, outpatient care, preventive services, and durable medical equipment. The standard monthly premium in 2024 is $174.70, with higher amounts for higher-income beneficiaries (IRMAA).

Part C - Medicare Advantage

Medicare Advantage plans replace Original Medicare with a bundled private plan. They almost always include Part D drug coverage and frequently add dental, vision, hearing, and wellness benefits. You'll choose between HMO, PPO, or Special Needs Plans (SNPs).

Part D - Prescription Drugs

Part D plans cover prescription medications. You can buy a standalone Part D plan or get one bundled into Medicare Advantage. Costs depend on the carrier's formulary (drug list), your specific prescriptions, and the pharmacy network.

Medigap - Supplemental Coverage

Medigap plans (also called Medicare Supplement Insurance) pay what Original Medicare doesn't - deductibles, copays, and coinsurance. Plans are standardized A through N, so a Plan G from one carrier covers the same as a Plan G from another. The differences are price and customer service.

How They Fit Together

You generally choose either Original Medicare + Medigap + standalone Part D, or Medicare Advantage with built-in Part D. We help you decide based on your doctors, prescriptions, and travel patterns.
