D. FO procedures
FO representatives should direct ALL beneficiaries requesting disenrollment – including telephone, mail and walk-in - to call Medicare directly at 1-800-MEDICARE (1-800-633-4227; TTY users should call 1-877-486-2048) to request disenrollment.
FOs may assist walk-in requests in SSA office by calling 1-800-MEDICARE in office. It is important that the beneficiary understands that a call to the SSA field office is not needed; rather, beneficiaries may call 1-800-MEDICARE on their own.
FOs ceased mailings and distribution of the CMS-566 form effective November 15, 2005).
FOs will forward to the appropriate CMS regional contacts all disenrollment requests received through the mail, including previously distributed CMS-566 forms. See HI 00208.073A for the CMS RO address.
