Medicare Costs, Coverage, and Benefits | Medicare Made Clear

There are four basic parts of Medicare: A, B, C and D. Each part helps pay for certain health care services. Each part also has certain costs that you may have to pay. Your Medicare costs will depend on what coverage you choose and on what health care services you use.

The parts of Medicare are like building blocks. They can be put together in different ways to provide coverage based on your needs. Start by learning about each part, including what it covers and what the costs are. You can go further down this page to learn about the different types of costs you might have with Medicare in general.

Medicare Isn't Free

Medicare helps pay for many health care items and services, but you will pay a share of the cost, too. Your Medicare costs include:

  • Premiums
  • Deductibles
  • Co-payments
  • Co-insurance

You pay premiums outright. Deductibles, co-payments (co-pays) and co-insurance are ways that Medicare shares the cost of your care with you.


A premium is a fixed amount that you pay. You may pay a premium to Medicare, to a private insurance company or to both, depending on your coverage. Most premiums are charged monthly and can change from year to year.



A deductible is a set amount that you pay out of pocket for covered services before your plan begins to pay.


Costs You Could Pay with Medicare


A co-payment, or co-pay, is a fixed amount you pay at the time you receive a covered service. For example, you might pay $20 each time you go to the doctor or $12 when you fill a prescription.



Co-insurance is when you and your plan split the cost of a covered service. For example, you might pay 20% of the allowed amount and your plan would pay 80%.


Out-of-Pocket Maximum

The out-of-pocket maximum is the total amount you might pay during a calendar year. The total does not include your premium or the cost of any services that are not covered by your plan. After you reach your out-of-pocket maximum, your plan pays 100% of the allowed amount for covered services for the rest of the year. Only certain types of private Medicare plans have an out-of-pocket maximum.

Cost-sharing Considerations

It’s easy to focus on just premiums when looking at Medicare costs. Premiums are regular monthly expenses that have to fit into a budget. And most of us are keenly aware of our monthly expenses.

But it’s a good idea to look at the big picture, too. For example, a plan with a low monthly premium might end up costing you more. You may have to pay a large deductible, or you might have high co-payments for doctor visits or prescriptions.

Think about how you will use your benefits and consider all the costs of Medicare. Also, you may be able to reduce your health care costs if you take steps to:

  • Understand Medicare cost sharing
  • Use health care services wisely
  • Adopt healthy lifestyle behaviors
