Medicare’s phone number is 1-800-MEDICARE (1-800-633-4227). Medicare plan holders who need to ask questions about claims, expenses and medical records can call this number. People who want to know more about Medicare's health plan should call the same number too.
Medicare plan holders who need to file a grievance due to a concern with the quality of care and services of a Medicare service provider should call 1-800-MEDICARE to get help with the filing and follow-up. However, if a person is calling for another patient’s behalf, that person must sign a Medicare Authorization to Disclose Personal Health Information first.
For people who have hearing and speech problems, the number to call is Medicare’s teletypewriter 1-877-486-2028. There is also a message relay center where TTY operators help send and interpret messages for people who don’t have a TTY.
