It’s not a bill. It’s a notice that people with Original Medicare get in the mail every 3 months for their Medicare Part A and Part B-covered services.
The MSN shows:
– All your services or supplies that providers and suppliers billed to Medicare during the 3-month period.
– What Medicare paid.
– The maximum amount you may owe the provider
You’ll get your MSN every 3 months if you get any services or medical supplies during that 3-month period. If you don’t get any services or medical supplies during that 3-month period you won’t get an MSN for that particular 3-month period.
If you need to change your address contact Social Security.
What should I do if I get this notice?
– If you have other insurance, check to see if it covers anything that Medicare didn’t.
– Keep your receipts and bills, and compare them to your MSN to be sure you got all the services, supplies, or equipment listed.
– If you paid a bill before you got your notice, compare your MSN with the bill to make sure you paid the right amount for your services.
– If an item or service is denied, call your doctor’s or other health care provider’s office to make sure they submitted the correct information
