If you already get Social Security benefits, we’ll automatically enroll you in Medicare Hospital Insurance (Part A) and Medical Insurance (Part B). We’ll mail you all the information you need a few months before you become eligible.
Note: Residents of Puerto Rico or foreign countries won’t automatically receive Part B. They must elect this benefit.
If you don’t get Social Security benefits and are not ready to apply for them yet, you should sign up for Medicare three months before your 65th birthday.
The easiest way to apply for Medicare is by using our online application.
If you don’t wish to apply online, make an appointment by calling us at 1-800-772-1213 (TTY 1-800-325-0778) 8:00 am to 5:30 pm, Monday through Friday.
Important Information about Medical Insurance (Part B) Coverage
Because you must pay a premium for Part B coverage, you can turn it down. However, if you decide to sign up for Part B later, your coverage can be delayed and 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.
