Most people will automatically be signed up for Part B of Medicare. If you are getting Social Security payments, you will be signed up prior to you 65th birthday. When you get the Medicare Card, it will show that Part A and B are in place. There are instructions on the card if you decide you do not want part B.
If you’re 65 or older and you aren’t getting Social Security or RRB benefits yet (for instance, because you’re still working), you won’t get Part A and Part B automatically. People of any age diagnosed with ESRD and who meet certain requirements are also eligible for Medicare Part A and Part B, but must sign up for them.
Medicare part B will be billed quarterly (for those not taking Social Security payments) or it will be deducted from your Social Security check if you are receiving payments.
You need to sign up by contacting Social Security at 1-800-772-1213. TTY users should call 1-800-325-0778. If you worked for a railroad, call your local RRB office or 1-877-772-5772 to learn more about signing up.
