Most doctors in the United States accept Medicare. To find a list of doctors in your area who accept Medicare and agree not to bill you for more than the approved Medicare amount for your visit or procedure, go to Medicare’s Care Compare website , select “Doctors & clinicians” under the Provider Type dropdown menu, and look for providers noted as charging the Medicare-approved amount. If you do not have access to a computer, you can also call 1-800-MEDICARE (1-800-633-4227), or call your doctor’s office and ask before you schedule an appointment.
