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).

Your bill pays for next month's coverage. Your bill lists the dates you're paying for.

Example

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? 

Medicare

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. If your bank offers an online bill payment service, you can use it to pay your Medicare premiums electronically. You can also pay by check, money order, or credit card/debit card. Or, sign up for Medicare Easy Pay, a free service that automatically deducts your premium payments from your savings or checking account each month.
