Coordination of Benefits
Coordination of Benefits is also called COB. It is your responsibility to update the COB with each insurance company.
If you have coverage with more than one insurance company, then the COB rules determine which policy will be the primary, then secondary insurance etc., to ensure that your claims are paid by the correct payer respectively.
Please note, some insurance companies require annual COB updates even if you or your dependents do NOT have other coverage.
To update COB, simply call the Member Services phone number on the back of your insurance card(s). You are responsible for claims denied due to COB.
