Coordination of Benefits (COB)
Coordination of benefits (COB) is the process for determining the order in which two or more health plans pay when a person is covered by more than one. It establishes which plan is primary, which is secondary, and how much each pays so that combined payment does not exceed the allowable charge.

Coordination of benefits (COB) is the process for determining the order in which two or more health plans pay when a person is covered by more than one. It establishes which plan is primary, which is secondary, and how much each pays so that combined payment does not exceed the allowable charge.
