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 . Most people don't get a bill from Medicare because they get these premiums deducted automatically from their Social Security (or Railroad Retirement Board) benefit.)
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. Example of when you'll get a bill
Your bill may also include premiums for past months if:
