The Centers for Medicare & Medicaid Services (CMS), a branch of the U.S. Department of Health and Human Services, is the Federal agency that administers the Medicare program and monitors the Medicaid programs offered by each state.
Medicare makes it easy for you to get information. You can find answers to general questions about eligibility, coverage, and Medicare Summary Notices (MSNs) on this Web site. You can also compare health and drug plans, Medigap policies, hospitals, nursing homes, and more!
For specific questions about your claims, medical records, or expenses, visit MyMedicare.gov, or call 1-800-MEDICARE.
For more specific contact information, see Where to Get Your Medicare Questions Answered.
If you want someone to be able to call 1-800-MEDICARE on your behalf, you need to fill out a “Medicare Authorization to Disclose Personal Health Information” form so Medicare can give your personal health information to someone other than you.
