If you are in Original Medicare, your doctor or other health care provider will file your claim with Medicare. You’ll receive a statement showing how much you’ll need to pay. If you do not receive a Medicare statement (Medicare Summary Notice or Explanation of Medicare Benefits), you’ll need to contact your local carrier to have them send you a copy. 

If you have supplemental insurance or Medigap, they may pay part of your costs. Check with your supplemental insurance company to find out what they will pay.
