Medicare Basics

Medicare Parts A, B, C and D Explained in Plain English

What Medicare Part A, Part B, Part C (Medicare Advantage) and Part D each cover, who is eligible, and what Original Medicare leaves out. A plain-English look with the limits spelled out.

Medicare, without the alphabet soup

Medicare is the federal health insurance program for people 65 and older and for some younger people with disabilities. It is split into parts with letters, and the letters are what make it feel confusing. Each part covers a different piece of your care.

Here is an honest, no-pressure look at what each part does, who qualifies, and what Medicare does not cover.

The four parts at a glance

What Original Medicare is

Original Medicare means Part A and Part B, run directly by the federal government. You can generally see any doctor or hospital in the country that accepts Medicare.

Many people pair Original Medicare with a Medigap (Medicare Supplement) policy and a Part D drug plan. Others choose a Medicare Advantage plan instead. We cover that choice in our Medicare Advantage vs. Medigap guide.

Who is eligible

Eligibility can have exceptions. Social Security decides it, and we're happy to help you sort out what applies to you.

What Original Medicare does not cover (so there are no surprises)

Premiums, deductibles and copays change from year to year and depend on the plan, where you live and, for some costs, your income. We won't quote a figure before we know your details, and we'll put the costs in front of you in writing before you decide.

Medicare by state

Common questions

What is Original Medicare?

Original Medicare is Part A (hospital insurance) and Part B (medical insurance), run by the federal government. Drug coverage (Part D) and Medigap are separate add-ons, and Medicare Advantage is an alternative that bundles these through a private plan.

Do I have to take all four parts?

No. Most people take Part A and Part B, and then choose either a Medicare Advantage plan (Part C) or a Medigap policy plus a Part D drug plan. Some people delay Part B if they have qualifying coverage through work. A licensed agent can help you check before you delay anything.

Is Medicare free?

Part A is premium-free for most people, but Part B has a monthly premium, and Medicare has deductibles and coinsurance. Medicare Advantage and Part D plans have their own costs as well. The amounts change every year.

What is the difference between Medicare and Medicaid?

Medicare is federal health insurance mainly for people 65 and older and some people with disabilities. Medicaid is a joint federal and state program for people with limited income and resources. Some people qualify for both.

Does Medicare cover long-term care?

Medicare covers some short-term skilled nursing care after a qualifying hospital stay, but it generally does not pay for long-term custodial care.

Does it cost anything to talk to an agent?

Talking through your options with us is free and comes with no obligation. Any plan you choose has its own premium, set by the plan and its insurance company.

You don't have to figure this out alone.
