How do I file a claim?

If you have Original Medicare, the law requires doctors and suppliers to file Medicare claims for covered services and supplies you get. 

If you have a Medicare Advantage Plan (Part C), these plans don’t have to file claims because Medicare pays these private insurance companies a set amount each month.

When do I need to file a claim?

You should only need to file a claim in very rare cases

Medicare claims must be filed no later than 12 months (or 1 full calendar year) after the date when the services were provided. If a claim isn’t filed within this time limit, Medicare can’t pay its share. For example, if you see your doctor on March 22, 2019, your doctor must file the Medicare claim for that visit no later than March 22, 2020. Check the “Medicare Summary Notice” (MSN) you get in the mail every 3 months, or log into your secure Medicare account to make sure claims are being filed in a timely way.
