What if my child’s medical care is covered by more than one insurance company?

Children who are covered under both parents’ group health insurance plans have one plan considered their primary insurance, while the other is considered their secondary insurance. The primary insurance pays the cost of claims first. The secondary plan pays the rest of the costs not covered by the primary plan, if the treatment is a covered benefit. When a child or teen is covered by the group policies of both parents, the primary insurance usually is the one belonging to the parent whose birthday comes earlier in the calendar year. There are exceptions to this and families should check the details of each policy.

When 2 policies are used, record-keeping becomes much more involved. But depending on how much coverage you get, it may be worthwhile to keep both if you can. For instance, if the second coverage is better and fills in gaps to pay for treatments that the primary insurance doesn’t cover, it may be worth keeping the second one. There are many factors to think about, and each situation is different.
