Retiring 101

About to retire? Here’s a quick overview of what your next steps should be.


If you are under 65 years old:

If you are turning 65 in the next 3 months , you can enroll in Medicare Part A and B on the Social Security Administration website. Click here to apply.


If you are 65+ years old:

Form CMS L 564 & Form CMS 40 B

 

If you are…

  • over 65 years old

  • on Medicare Part A, and

  • leaving a group health insurance plan to go on Medicare

…then you need your employer to complete form CMS L 564. If applicable, your employer will also need to complete a separate form CMS L 564 for your spouse as well. Once you receive the completed form(s) from your employer, you will will need to submit it to the Social Security Administration (SSA).

 

In addition to your CMS L 564 form(s), you will need to submit form CMS 40 B to the SSA. You should include your Medicare start date in the remarks section of form CMS 40 B. If applicable, you will also need to complete a separate CMS 40 B form for your spouse.

Note: Group health plans generally end at the end of the month in which you retire.  Medicare plans should start the first of the following month.  Example: Rich is retiring on April 4, 2023.  His group plan will end on April 30, 2023 and he will request a Medicare Part B effective date of May 1, 2023.  He will also need to submit a form CMS L 564 and C S 40 B for his wife, Jean.
