In general, your dependents will be eligible for medical, vision, and prescription drug benefits while you are eligible for Class 1 Insurance. Children and stepchildren can only be covered until they turn age 26. Eligibility for permanently disabled children may be extended. Spouses can be covered while married to the member. Your dependents will become eligible on the later of two dates: The date on which you become eligible, or The date of your dependent’s qualifying event (marriage, birth, adoption, etc.) Even though your dependent’s eligibility may be retroactive based on the above rules, enrollment and claims submissions should be done as soon as possible to avoid claims being denied due to untimely filing.
