2021 Part A Premiums:

Most people do not have a premium for Part A if they or a spouse have paid into Medicare taxes for a certain amount of time. If you do not qualify for premium-free Part A, you can buy Part A.

People who buy Part A will pay a premium of either $259 or $471 each month in 2021 depending on how long they or their spouse worked and paid Medicare taxes. If you choose NOT to buy Part A, you can still buy Part B.
