Coordination of Benefits (COB) is a procedure for paying health care expenses when people are covered by more than one dental plan. The goal of COB is to make sure the cost of the dental procedure is covered within the scope of the plans, without exceeding the amount of the actual bill.
If you or your dependent are covered by two or more dental plans, you or your dependent’s coverage will be coordinated in accordance with the coordination of benefit rules set forth in your policies.
