To contact Medicare by phone, call their toll-free number at 1-800-MEDICARE, or 1-800-633-4227. They also provide a TTY, or text telephone, number for the hearing impaired at 1-877-486-2048.
For those who want someone else to contact Medicare on their behalf, the Medicare website offers an authorization form to disclose personal health information. Medicare recipients can fill out this form and mail it to Medicare BCC, Written Authorization Dept., P.O. Box 1270, Lawrence, Kansas, 66044. Once Medicare receives the form, the person mentioned on the form can call the Medicare toll-free number on behalf of the Medicare recipient and get the personal information needed.
