The way coordination of benefits works is that one health insurance plan becomes identified as the primary health insurance plan. Then, the second one is the secondary plan. In the event of a health insurance claim, the primary health insurance plan will pay out first, then the second one will kick in to pay towards the remaining cost that the first plan didn't cover completely.
- Avoid duplicate payments by making sure the two plans don't pay more than the total amount of the claim.
- Establish which plan is primary and which plan is secondary—the plan that pays first and the plan that pays any remaining balance after your share of the costs is deducted.
