Initial Enrollment Questionnaire (IEQ)

What is it?

The "Initial Enrollment Questionnaire" (IEQ) asks about other health insurance you have that might pay before Medicare does, like group health plan coverage from your or a family member's employer, liability insurance, or workers' compensation.

When should I get it?

The actual IEQ isn't mailed to you, but you'll get a letter with details about how to complete the IEQ online at about 3 months before your Medicare coverage starts. The letter will include your username and an initial password.

Who sends it?


What should I do if I get this notice?

Follow the instructions and submit the IEQ to Medicare so your bills are paid correctly and on time.



The IEQ will be available online 90 days before and up to 180 days after your entitlement date.  If you try to fill it out online before or after this time, you won't be able to access it.


If you have questions or need to change what’s in your IEQ, call the Benefits Coordination & Recovery Center (BCRC) at 1-855-798-2627. TTY users should call 1-855-797-2627.
