How Do I Register For Medicare Part D? 
To register for Medicare Part D , you can call 1-800-633-4227 . If you are hard of hearing and use TTY , call 1-877-486-2048 . You can sign up online at medicare.gov . A website I find particularly helpful is WEBSITELINK . Here you can compare the details of Medicare Part D plans , and when you find the one you want , you will be provided with how to enroll .
