The Medicare Initial Enrollment Questionnaire






What is the Initial Enrollment Questionnaire?


About three months before your entitlement to Medicare, you are mailed the Initial Enrollment Questionnaire (IEQ). The IEQ asks whether you have other insurance that pays before Medicare. To ensure correct payment of your Medicare claims, it is important to complete and return the IEQ timely. The questionnaire takes only 5 minutes to complete.

Si usted desea recibir el IEQ en espanol, por favor llame al COB Contractor al telefono 1-800-999-1118 or TTY/TDD 1-800-318-8782 (toll-free).
