Coordination of Benefits (COB)

Coordination of Benefits (COB) is a process used to determine the order in which multiple insurance plans pay for a patient’s healthcare expenses when the patient is covered by more than one insurance policy. This process ensures that claims are paid accurately and prevents overpayment or duplication of benefits.

COB guidelines typically establish which insurance plan is primary, responsible for paying first, and which is secondary, covering the remaining costs. Effective coordination of benefits helps streamline the billing process, reduces patient out-of-pocket expenses, and ensures that providers receive appropriate reimbursement for the services rendered.
