When you’re unhappy with the quality of your health care, you might first want to talk with the person who gave you the care. If you don’t want to talk to that person or need more help, you can file a Medicare complaint. Filing a complaint is your right, so if you think you aren’t getting high-quality care, we want to know.

How you file a complaint depends on what it’s about:

If you’re enrolled in a Medicare health or drug plan, each plan has its own rules for filing Medicare complaints. If you still need help after you file a complaint with your plan, call 1-800-MEDICARE (1-800-633-4227). TTY users can call 1-877-486-2048.

If you’ve contacted 1-800-MEDICARE about a Medicare complaint and still need help, ask the person you talk with at 1-800-MEDICARE to send your complaint to the Medicare Beneficiary Ombudsman. The Ombudsman staff will help make sure your complaint is resolved.

You can also file an appeal if you disagree with a coverage or payment decision made by Medicare, your Medicare health plan, or Medicare Prescription Drug Plan.

For other kinds of Medicare-related complaints, call your State Health Insurance Assistance Program (SHIP) for free, personalized help.
