How Do I Apply For Medicare?

These instructions apply to enrollment in Medicare Parts A (Hospital) and B (Medical) - the two primary parts of Medicare for which most people become eligible at age 65.

In addition to Medicare Parts A and B, most people will need to enroll in a Medicare Supplement - also called Medigap - as well as a Medicare Part D drug plan.

In most states you can enroll in a Medicare Supplement up to 6 months prior to your Medicare Eligibility date - including prior to enrolling in Medicare Parts A and B and receiving your Medicare card.  

You will not be able to enroll in your Medicare Part D drug plan until you receive your Medicare Beneficiary Identifier number (MBI) which will be shown on your Medicare card.

The way in which you apply for Medicare depends on your situation.

Which of the following situations applies to you?

  1. I am turning 65 in the next 6 months. I am collecting Social Security monthly benefits and I want to start full Medicare when I am eligible on the 1st day of the month in which I turn 65.
  2. I am turning 65 in the next 6 months. I am NOT collecting Social Security monthly benefits and I want to start full Medicare when I am eligible on the 1st day of the month in which I turn 65.
  3. I am 65 years old or older and am losing employer health insurance either through myself or my spouse in the next 6 months.
  4. I am 65 years old or older and currently have employer health insurance either through myself or my spouse but would like to leave that insurance and switch to full Medicare.

Scenario #1: 

I am turning 65 in the next 6 months. I am collecting Social Security monthly benefits and I want to start full Medicare as soon as I am eligible on the 1st day of the month in which I turn 65.

If you are turning 65 in the next 6 months and are collecting Social Security monthly benefits, you do not have to do anything to sign up for Medicare Parts A and B to take effect when you are 1st eligible.

You will be automatically enrolled in Medicare Parts A and B and will receive your Medicare card in the mail around the 10th of the month in the 4th month before the month you turn 65.

For example, if your birthday is June 20, 1956, you will receive your Medicare card showing an effective date of June 1, 2021 for Medicare Parts A and B around February 10, 2021.

Scenario #2: 

I am turning 65 in the next 6 months. I am NOT collecting Social Security monthly benefits and I want to start full Medicare as soon as I am eligible on the 1st day of the month in which I turn 65.

If you are turning 65 in the next 6 months and are NOT collecting Social Security monthly benefits, you will need to take action to enroll in Medicare Parts A and B when you are within 3 months of your Medicare eligibility date.

As a reminder, your Medicare eligibility date is the 1st day of the month in which you turn 65 unless your birthday falls on the 1st of the month.  If your birthday falls on the 1st your Medicare eligibility date is the 1st day of the month BEFORE the month in which you turn 65.

You can enroll in Medicare Parts A and B in one of three ways

  1. You can apply online by visiting the Social Security Administration website at Apply For Medicare Only.  You should follow the directions to apply for Medicare Parts A and B.  Your effective date will be your Medicare eligibility date described above.
  2. You can call your local Social Security office.  This is not highly recommended because you will usually be assigned an appointment several weeks in the future whereas the online enrollment will be immediate.
  3. You can visit your local Social Security office.  This option has not been available since the onset of the COVID-19 pandemic.

Scenario #3: 

I am 65 years old or older and am losing employer health insurance either through myself or my spouse in the next 6 months 

If you are 65 years old or older and are losing coverage you have through an employer or though your spouse’s employer - either voluntarily or involuntarily - you will have a Special Election period to enroll in Medicare Part B and, if you do not already have Medicare Part A, then Medicare Part A also.

The following are the four steps you must take to enroll in Medicare Part B - and Medicare Part A if you do not already have Medicare Part A - when you are leaving employer coverage.

 

  1. You need to contact your local Social Security office via phone and tell them you need to enroll in Medicare Part B due to your leaving employer health insurance.  We highly recommend calling your local Social Security office rather than the national toll-free number. Also, please write down the name of the person with whom you speak in the event you need to refer back to the call at a later occasion. If you do not already have Medicare Part A you will be automatically enrolled in Medicare Part A when you enroll in Medicare Part B.

  2. You will need to have your employer complete and sign Employer Form CMS-L564E.  You can download this form by clicking on this link.  This form will document that you have had health insurance through your employer since you were eligible for Medicare and when this coverage is ending.  If both you and your spouse are leaving the employer coverage, you will need to have a separate form completed and signed for each of you.

  3. You will need to complete and sign Form - CMS40B-E. You can download this form by clicking on this link. This is your application for Medicare Part B.  If both you and your spouse are enrolling in Medicare Part B, you will need to have a separate signed for each of you.

  4. You will need to mail or fax these completed and signed documents to your local Social Security office at the address or fax number you are provided in Step 1 above.

Scenario #4: 

I am 65 years old or older and currently have employer health insurance either through myself or my spouse but, though I am not leaving this my employer, I would like to leave their insurance and switch to full Medicare.

If you are 65 years old or older and wish to leave your employer health insurance to go on full Medicare, you can do this at any time. You do not need to wait until either your employer’s yearly election period or Medicare’s Annual Enrollment Period.

You will have a Special Election period to enroll in Medicare Part B and, if you do not already have Medicare Part A, then Medicare Part A also.

You should follow the steps prescribed in Scenario #3 above.

Very importantly, federal law prohibits your employer from encouraging you to leave their insurance to go on full Medicare - including by providing financial incentives to do so.  This is a decision you should make on your open based on your unique needs and preferences.
