Dependent Coverage

Eligible dependents of a member may participate in the same health, dental and vision plans as the member. For this reason, members wishing to add a dependent who is not enrolled in Medicare Parts A and B must disenroll from the Medicare Advantage plan in which they are enrolled and, instead, enroll in one of the non-Medicare Advantage health plans under the State Employees Group Insurance Program.  If adding a non-Medicare dependent outside the annual fall Open Enrollment Period, you must have a qualifying change in status event and must request the addition within 60 days of the event occurring.  You must notify MyBenefits Service Center (MBSC) of your qualifying-change-in-status event by going online at, or by calling 844-251-1777 M-F, 8:00 AM - 6:00 PM CT.  You will be required to provide eligibility documentation within the allotted time frame.

Documentation requirements must be met for the dependent to be added to and/or remain on the coverage.
