Last Updated: August 6, 2020

For many people, signing up for Medicare Part B doesn’t require you to leave the comfort of home.  Please visit our Medicare Part B webpage if:

  1. You are already enrolled in Medicare Part A.
  2. You would like to enroll in Part B during the Special Enrollment Period.

You can complete form CMS-40B (Application for Enrollment in Medicare – Part B [Medical Insurance]) and CMS-L564 (Request for Employment Information) online.

You can also fax the CMS-40B and CMS-L564 to 1-833-914-2016; or return forms by mail to your local Social Security office.  Please contact Social Security at 1-800-772-1213 (TTY 1-800-325-0778) if you have any questions.  

 Note:  When completing the forms:

  • State, “I want Part B coverage to begin (MM/YY)” in the remarks section of the CMS-40B form or online application.
  • If your employer is unable to complete Section B, please complete that portion as best you can on behalf of your employer without your employer’s signature.
  • Submit one of the following types of secondary evidence by uploading it from a saved document on your computer:
    • Income tax returns that show health insurance premiums paid.
    • W-2s reflecting pre-tax medical contributions.
    • Pay stubs that reflect health insurance premium deductions.
    • Health insurance cards with a policy effective date.
    • Explanations of benefits paid by the GHP or LGHP.
    • Statements or receipts that reflect payment of health insurance premiums.

 Please let your friends and loved ones know about this online, mail, or fax option.

    In July 2020, I turned 64 and am currently enrolled in HSA with my employer through December, 2020. It is my understanding to enroll in Medicare at age 65 (July 2021 in my case), it must be at least 7 months that I have stopped contributing to my HSA without penalities. As a result, I cannot enroll in Medicare A or B until July 2021, OR no later than October, 2021 (3 months after turning 65). Is my understanding correct? Please advise. Thank you.

      Hi there. Thanks for using our blog. 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. Check out our Medicare Benefits web page for additional details.

      Hi Wisarat, thanks for using our blog. You can contact your local Social Security office. Please look for the general inquiry telephone number at the Social Security Office Locator. The number may appear under Show Additional Office Information. Please be aware that our call wait times are longer than normal. We hope this information helps.

    The title is misleading. Fax or mail is most definitely NOT online. Would be a nice option could even upload the forms.
