What Is Form CMS-L564?

Form CMS-L564 is used to prove that you or your spouse had group health plan coverage based on current employment when you apply for Medicare Part B during a Special Enrollment Period (SEP). This form is essential to avoid the late enrollment penalty that applies when you sign up for Medicare Part B outside the general enrollment period.

Common Mistakes to Avoid

Not having the employer complete Section B — both sections must be filled for the form to be valid
Submitting the form more than 8 months after the employer coverage ended (the SEP window is 8 months)
Confusing COBRA coverage with employer group coverage — COBRA does not qualify for the SEP
Not including the form when applying for Medicare Part B, resulting in the late enrollment penalty
Former employers refusing to complete the form — contact CMS for assistance if this happens

Frequently Asked Questions

What is the Medicare Part B late enrollment penalty?

The penalty is an additional 10% of the Part B premium for each full 12-month period you could have had Part B but didn't enroll. This penalty lasts for as long as you have Part B. Form CMS-L564 helps you avoid it.

Does COBRA count as current employer coverage?

No. COBRA continuation coverage does not count as coverage based on current employment for Medicare SEP purposes. The 8-month SEP window begins when the active employer coverage ends, not when COBRA ends.

What if my employer no longer exists?

If your former employer is no longer in business, you can provide alternative evidence of coverage, such as W-2s showing employer contributions, old insurance cards, or pay stubs showing health insurance deductions. Contact your local Social Security office for guidance.
