Learn about Medicare
Medicare is our country’s health insurance program for people age 65 or older. Certain people younger than age 65 can qualify for Medicare, too, including those with disabilities and those who have permanent kidney failure.
Already Enrolled in Medicare
If you already have Medicare, you can get information and services online. Find out how to manage your benefits.
If you already have Medicare Part A and wish to sign up for Medicare Part B, please complete form CMS 40-B, Application for Enrollment in Medicare - Part B (Medical Insurance), and take or mail it to your local Social Security office.
Anyone who has Medicare can get Medicare prescription drug coverage. Some people with limited resources and income also may be able to get Extra Help to pay for the costs.
Applying for Medicare
When you apply for Medicare, you can sign up for Part A (Hospital Insurance) and Part B (Medical Insurance). Because you must pay a premium for Part B coverage, you can turn it down. However, if you decide to enroll in Part B later on, you may have to pay a late enrollment penalty for as long as you have Part B coverage. Your monthly premium will go up 10 percent for each 12-month period you were eligible for Part B, but didn’t sign up for it, unless you qualify for a special enrollment period.
If you’re eligible at age 65, your initial enrollment period begins three months before your 65th birthday, includes the month you turn age 65, and ends three months after that birthday. However, if you don’t enroll in Medicare Part B during your initial enrollment period, you have another chance each year to sign up during a “general enrollment period” from January 1 through March 31. Your coverage begins on July 1 of the year you enroll. Click here for more information: https://www.ssa.gov/pubs/EN-05-10043.pdf
If you live in Puerto Rico you will not receive Medicare Medical Insurance (Medicare Part B) automatically.

To sign up, please call our toll-free number at 1-800-772-1213 (TTY 1-800-325-0778) or contact your local Social Security office.

Questions about our online application
You can use our online Medicare application if you:
- Are at least 64 years and 9 months old;
- Want to sign up for Medicare but do not currently have ANY Medicare coverage;
- Do not want to start receiving Social Security benefits at this time; and
- Are not currently receiving Social Security retirement, disability or survivors benefits.
You should sign up for Medicare three months before reaching age 65, even if you are not ready to start receiving retirement benefits. You can opt out of receiving cash retirement benefits now once you are in the online application. Then you can apply online for retirement benefits later.
With our online application, you can sign up for Medicare Part A (Hospital Insurance) and Part B (Medical Insurance). Because you must pay a premium for Part B coverage, you can turn it down.
If choose not to enroll in Medicare Part B and then decide to do so later, your coverage may be delayed and you may have to pay a higher monthly premium for as long as you have Part B. Your monthly premium will go up 10 percent for each 12-month period you were eligible for Part B, but didn’t sign up for it, unless you qualify for a "Special Enrollment Period."
Special Enrollment Period (SEP)
If you have medical insurance coverage under a group health plan based on your or your spouse's current employment, you may not need to apply for Medicare Part B at age 65. You may qualify for a "Special Enrollment Period" (SEP) that will let you sign up for Part B during:
- Any month you remain covered under the group health plan and your, or your spouse's, employment continues; or
- The 8-month period that begins with the month after your group health plan coverage or the employment it is based on ends, whichever comes first.
