The short answer

Medicare has four main parts: Part A covers hospital care, Part B covers doctor visits and outpatient care, Part C is Medicare Advantage (a private plan alternative), and Part D covers prescription drugs.

The full explanation

Medicare is divided into parts, and each one covers something different.Part A is hospital insurance. It covers inpatient hospital stays, skilled nursing facility care after a qualifying hospital stay, hospice, and some home health services. Most people don't pay a monthly premium for Part A because they or a spouse paid Medicare taxes during their working years.Part B is medical insurance. It covers doctor visits, outpatient procedures, preventive care, lab work, and durable medical equipment like wheelchairs. Part B has a monthly premium, and most people pay the standard amount, though higher earners pay more through a surcharge called IRMAA.Part C is Medicare Advantage. These are private insurance plans approved by Medicare that bundle Part A and Part B coverage, and usually Part D as well. They often include extras like dental, vision, and hearing. The trade-off is that you typically work within a defined network of providers.Part D is prescription drug coverage. If you're on Original Medicare (Parts A and B), you add Part D through a separate standalone plan. Medicare Advantage plans usually include drug coverage built in.Medigap, sometimes called Medicare Supplement, isn't technically a numbered part, but it's worth knowing about. These are private plans that help cover the gaps Original Medicare leaves, like copays and deductibles. You can't pair Medigap with a Medicare Advantage plan. All costs and plan details vary and should be verified annually.

Utah

 specifically

In Utah, plan fit often comes down to provider network access. Intermountain Health, University of Utah Health, and rural hospital access can matter just as much as premium.

What this means for you

For you, this means Medicare isn't one single thing, and the choices you make about how to combine these parts will shape what you pay and how you access care.
