When there are questions about eligibility, CMS will make the determination. A beneficiary may contact CMS if they want to know all plans in their area for enrollment assistance, or if they have any questions. They can reach CMS by calling 1-800-MEDICARE (1-800-633-4227) anytime, 24 hours a day, 7 days a week. TTY users should call 1-877-486-2048. If the beneficiary knows what plan they want to select, they can call the plan or their broker/agent directly to enroll. To review up-to-date information, you may go to the FEMA Disaster Declarations website. This Information is updated at least weekly.
