Medicare Premium Bill (CMS-500)

What is it? 

The “Medicare Premium Bill” (CMS-500) is a bill for people who pay Medicare directly for their Part A premium, Part B premium, and/or Part D IRMAA (an extra amount in addition to the Medicare Part D premium).


If you’re having trouble paying your premiums now or if you have any questions about your Medicare premium bill, call us at 1-800-MEDICARE. TTY: 1-877-486-2048.

Your bill pays for next month's coverage (and future months if you get the bill every 3 months). Your bill lists the dates you're paying for.


If you get a bill each month, the bill you get in April is for May coverage. If you get a bill every 3 months, the bill you get in April is for May, June, and July coverage.

Your bill may also include premiums for past months if you missed a payment, if you're getting your first bill, or if you had a change in your premium amount. Learn more about what may change the amount of a Part A premium, Part B premium, or Part D premium.

When should I get it? 

On or about the 10th of the month.

Who sends it? 


What should I do if I get this bill? 

Follow the instructions on the bill to pay the total amount due, so Medicare gets your payment by the 25th of the month. To pay your bill, you can:


To pay through your secure account, you'll need:

  • A copy of your Medicare bill to enter the amount you owe
  • Your credit or debit card information

You'll get a confirmation number when you make your payment. Your credit/debit card statement will show a payment made to "CMS Medicare." You can't set up payments automatically each month — you'll need to log into your account each time you need to pay your premium.
