In outpatient coverage scenarios, which parent’s plan gets priority if both carry family coverage?

In determining which parent's insurance plan is primary for outpatient coverage when both parents have family coverage, the priority is typically given to the parent with custody. This guideline aligns with the "birthday rule," which states that the insurance plan of the parent whose birthday falls earlier in the calendar year is considered primary; however, when custody is involved, the custodial parent's plan typically has precedence because that parent is usually more responsible for the child's healthcare decisions and finances.

Therefore, having custody implies a more consistent involvement in the child's care, making their plan the primary coverage. This prioritization helps ensure that the child receives uninterrupted access to medical services through the responsible caregiver's policy.
