Administration at 1-800-772-1213 to enroll in Medicare or to ask questions about whether you are eligible. You can also visit their web site at www.socialsecurity.gov.

The Medicare.gov Web site also has a tool to help you determine if you are eligibile for Medicare and when you can enroll.  It is called the Medicare Eligibility Tool.

If you already receive benefits from Social Security:

If you already get benefits from Social Security or the Railroad Retirement Board, you are automatically entitled to Medicare Part A (Hospital Insurance) and Part B (Medical Insurance) starting the first day of the month you turn age 65. You will not need to do anything to enroll. Your Medicare card will be mailed to you about 3 months before your 65th birthday. If your 65th birthday is February 20, 2010, your Medicare effective date would be February 1, 2010. (Note: if your birthday is on the 1st day of any month, Medicare Part A and Part B will be effective the 1st day of the prior month. For example, if your 65th birthday is February 1, 2010, your Medicare effective date would be January 1, 2010.)

If you are not getting Social Security benefits:

If you are not getting Social Security benefits, you can apply for retirement benefits online. If you would like to file for Medicare only, you can apply by calling 1-800-772-1213.

If you are under age 65 and disabled:

If you are under age 65 and disabled, and have been entitled to disability benefits under Social Security or the Railroad Retirement Board for 24 months, you will be automatically entitled to Medicare Part A and Part B beginning the 25th month of disability benefit entitlement. You will not need to do anything to enroll in Medicare. Your Medicare card will be mailed to you about 3 months before your Medicare entitlement date. (Note: If you are under age 65 and have Lou Gehrig's disease (ALS), you get your Medicare benefits the first month you get disability benefits from Social Security or the Railroad Retirement Board.) For more information about enrollment, call the Social Security Administration at 1-800-772-1213 or visit the Social Security web site. See also Social Security's Medicare FAQs.

It only takes about 10 minutes to sign up for Medicare online. Click the video for a step-by-step guide or keep reading for a summary.

When enrolling in Medicare for the first time, you can sign up at www.ssa.gov. You’ll have the option to enroll in both Social Security retirement benefits AND Medicare benefits…OR…just “Medicare Only”.

NOTE: If you’re already receiving Social Security retirement benefits at least 4 months prior to turning age 65, you’ll be automatically enrolled in Medicare Parts A & B. Your red, white, and blue Medicare card will arrive by mail about 3 1/2 months prior to the 1st of the month of your birthday month.

Create a My Social Security Account First

You need a My Social Security account first in order to complete an online application for Medicare and/or Social Security retirement benefits. Be sure to complete this step, if you haven’t do so already. You can follow the instructions detailed in our video below (How to Create a My Social Security Account (using Login.gov).

Complete the Application

When you’re ready to begin the “Medicare Only” application, you can apply for benefits by clicking “Start a New Application”. There, you’ll enter some general information about yourself. Then you’ll move on through the application where you have a few options:

  • If you want Part A (hospital) only

    • Part A is assumed when completing an online application for Medicare. It won’t ask if you want Part A. But when the question about enrolling in Part B comes around, you’ll need to answer NO to Part B.

  • If you want Part A (hospital) AND Part B (medical/outpatient)

    • Answer YES to the question about enrolling in Part B on the application. This will give you both Part A & Part B.

  • If you want Medicare AND Social Security benefits

    • Part A is automatic when you enroll in Social Security benefits and are also Medicare-eligible.

    • If you want Part B, you’ll have the option to add Part B as well.

Remember to watch our video at the top of the page for a breakdown of all the questions asked throughout the application.

Check the Application Status (Benefit verification Letter)

Once the application is complete, you can check the status of your enrollment anytime in your My Social Security account. Simply click the “Benefit Verification Letter” link to see if your Medicare enrollment has been completed or if an application for benefits is still processing.

If the letter shows your Part A and/or Part B start date and your Medicare # is visible, your Medicare card is on its way. Generally speaking, you can expect your Medicare card to arrive by mail within 4-6 weeks (sometimes sooner, sometimes it takes longer).

Note: The Benefit Verification Letter is proof of Medicare coverage, so you can use it to move forward with signing up for a Medicare Supplement (Medigap) plan, Part D prescription drug plan, or Medicare Advantage plan. You don’t necessarily have to wait for your Medicare card to arrive by mail if your Medicare number and start dates are displayed on the Benefit Verification Letter.
