If you do not receive Social Security benefits, then you will need to sign up for Medicare by calling the Social Security Administration at 800-772-1213 or online at http://www.socialsecurity.gov/medicareonly/ . It is best to do it as early as possible so your coverage begins as soon as you turn 65.
