Understanding Medicare: choosing the right plan for your needs

Medicare has four parts and several ways to combine them, which is why it feels harder than it is. Here's each part in plain terms, and the questions that actually decide which combination fits you.

Part A — hospital insurance

Covers inpatient hospital stays, skilled nursing facility care, hospice, and some home health services. It's premium-free for most people, earned through the Medicare taxes you or your spouse paid while working. This is the foundation, and it's the part that protects you from the largest single bills.

Part B — medical insurance

Covers two kinds of care: medically necessary services such as doctor visits, lab tests, surgeries, and home health care; and preventive services designed to catch problems early. Unlike Part A, everyone pays a monthly Part B premium, and higher-income households pay more.

Part C — Medicare Advantage

An alternative way to receive your benefits, offered by private insurers approved by Medicare. Advantage plans cover everything Parts A and B cover, and usually add extras Original Medicare doesn't — dental, vision, hearing — with prescription coverage typically bundled in. The trade is that you work within the plan's provider network.

Part D — prescription drug coverage

Adds drug coverage, either as a stand-alone plan alongside Original Medicare or built into an Advantage plan. If you take regular medications this is where a large share of your yearly costs live — and since 2025, Part D caps what you pay out of pocket for covered drugs in a year, which changed the calculation for people with expensive prescriptions.

The part nobody tells you about

Original Medicare on its own has no annual out-of-pocket maximum. The 20% coinsurance keeps going regardless of how large the bills get. That's the gap Medicare Supplement (Medigap) plans exist to close — and it's why most people pair Original Medicare with something, rather than leaving it bare.

Assessing your own needs

Forget the brochures for a moment and answer these:

• How often do you actually see a doctor?
• What prescriptions do you take, and what do they cost you now?
• Any surgery or procedure you expect in the next year or two?
• Which doctors and hospitals do you want to keep?
• What can your budget absorb — as a monthly premium, and as a bad year?

Those five answers point at the right combination faster than any comparison chart. And they're worth revisiting every year during the Annual Enrollment Period, because plans change their costs and networks annually — and so do you.
