What are the parts of Medicare?

The different parts of Medicare help cover specific services:

  • Medicare Part A (Hospital Insurance)
    Part A covers inpatient hospital stays, care in a skilled nursing facility, hospice care, and some home health care.
  • Medicare Part B (Medical Insurance)
    Part B covers certain doctors’ services, outpatient care, medical supplies, and preventive services.
  • Medicare Part D (prescription drug coverage)
    Helps cover the cost of prescription drugs (including many recommended shots or vaccines).

Part A & Part B Premiums

Most people don’t pay a monthly premium for Part A.
You usually don’t pay a monthly premium for Part A if you or your spouse paid Medicare taxes while working for a certain amount of time. This is sometimes called “premium-free Part A.”
Learn more about premium-free Part A.

If you aren’t eligible for premium-free Part A, you may be able to buy Part A. You’ll pay up to $505 each month in 2024. If you paid Medicare taxes for less than 30 quarters, the standard Part A premium is $505. If you paid Medicare taxes for 30–39 quarters, the standard Part A premium is $278.

Most people will pay the standard Part B premium amount. The standard Part B premium amount in 2024 is $174.70. If your modified adjusted gross income as reported on your IRS tax return from 2 years ago is above a certain amount, you’ll pay the standard premium amount and an Income Related Monthly Adjustment Amount (IRMAA). IRMAA is an extra charge added to your premium.

How does Medicare work?

With Medicare, you have options in how you get your coverage. Once you enroll, you’ll need to decide how you’ll get your Medicare coverage. There are 2 main ways:

Medicare prescription drug coverage (Part D)

Medicare drug coverage helps pay for prescription drugs you need. To get Medicare drug coverage, you must join a Medicare-approved plan that offers drug coverage (this includes Medicare drug plans and Medicare Advantage Plans with drug coverage).

Learn more about how to get Medicare drug coverage.

Each plan can vary in cost and specific drugs covered, but must give at least a standard level of coverage set by Medicare. Medicare drug coverage includes generic and brand-name drugs. Plans can vary the list of prescription drugs they cover (called a formulary) and how they place drugs into different “tiers” on their formularies.

Plans have different monthly premiums. You’ll also have other costs throughout the year in a Medicare drug plan. How much you pay for each drug depends on which plan you choose.

When you have other insurance, there’s more than one “payer” for your coverage.
