Enrolling in Medicare

Are You Turning 65?

You should sign-up for Medicare benefits a few months before you turn 65 to avoid a break in coverage. You're eligible to enroll in Medicare Part B at age 65 even if you are not eligible for Medicare Part A.

• Sign up for Part B when first eligible to avoid a late enrollment penalty.
• If your sponsor is on active duty, you may delay Part B enrollment without penalty.
• Get started with Medicare

If you didn't sign up for Medicare Part B when you first became eligible, or you dropped it, you can sign up during Medicare's general enrollment period (January 1 - March 31 each year). Your Part B and TRICARE For Life coverage will start the first day of the month after you sign up. You may have to pay a Medicare Part B Late Enrollment PenaltyYour monthly premium for Part B may go up 10% for each full 12-month period that you could have had Part B, but didn't sign up for it..

Do you Have Employer-Sponsored Group Coverage?

• If so, you may sign up later for Part B. However, you won't have TRICARE coverage if you don't have Medicare Part B.

Do You Have a Disability?

• If you're receiving Social Security Disability payments, you'll automatically get Medicare Part A and Part B in the 25th month of disability.

Medicare Part B Premiums

Your Part B premium is based on your income. Most people pay the standard monthly premium. For more information about Part B premiums, call Social Security at 1-800-772-1213 (TTY: 1-800-325-0778).

Your Part B premiums are taken from your monthly payment if you’re getting:

• Social Security Retirement,
• Social Security Disability, or
• Railroad Retirement Board (RRB) benefits.

If you're getting Social Security Retirement or Disability, or Railroad Retirement Board (RRB) benefits, your Part B premiums are taken from your monthly payment. If not, you'll be billed quarterly for your Part B premiums.
