Sign up for Medicare Part B Online, by Fax or Mail

(Posted on August 6, 2020 by Darlynda Bogle, Assistant Deputy Commissioner)


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.
