Check the Medicare Summary Notice carefully. Make sure Medicare wasnt billed for services, medical supplies, or equipment you didnt get.
If you have questions about your bill or the services listed on the notice, call the health care provider or MAC in your state. The telephone number for the MAC is at the top of the Medicare Summary Notice.
You can also call 1-800-MEDICARE (1-800-633-4227) to get the telephone number. TTY users should call 1-877-486-2048. If you disagree with what is covered or paid, you have the right to file an appeal.
