Disability benefits
People under 65 who have received Social Security or certain Railroad Retirement disability benefits for 24 months.
End-Stage Renal Disease
People of any age with permanent kidney failure requiring dialysis or a transplant.
ALS
People with ALS (Lou Gehrig’s disease) usually qualify as soon as disability benefits begin.
Signing Up
Will You Be Enrolled Automatically?
Some people are enrolled in Parts A and B automatically, while others need to sign up through Social Security.
- Automatic enrollmentIf you already receive Social Security or Railroad Retirement benefits before 65, you are usually enrolled automatically and receive your card in the mail.
- Manual enrollmentIf you are not yet receiving benefits, you typically sign up through Social Security online, by phone, or at a local office.
- Still working at 65?If you have coverage through your own or your spouse’s current employer, you may be able to delay Part B without a penalty. Rules depend on employer size.
