How does a person keep track of the services that Medicare bills and pays for?

If a person is in Original Medicare, he or she will get a Medicare Summary Notice (MSN) in the mail every three months if he or she had a Medicare-covered service during that period. The notice lists the services the person you care for received and the amount he or she may be billed by a hospital, doctor, or other provider. These notices are sent by companies that handle bills for Medicare.

Notices and bills for Medicare Advantage Plans and Medigap policies will look different than the MSN for people in Original Medicare.

If you have a question about a Medicare Advantage Plan or Medigap policy, you will need to call the benefits coordinator at the company or health plan that offers the plan. To locate telephone numbers, you can look at the notice or bill from the plan.
