My insurance company denied my claim because of a Coordination of Benefits (COB) Issue. What should I do next?

In many cases it’s because they’re listed as your secondary insurer. If you want to change that, you’ll have to:

  • Call your insurance company using the number on the back of your insurance card
  • Let them know you want to update your "coordination of benefits" and make them your “primary insurance” company. Note the name of the representative that you spoke with and ask for a call reference number.
  • Send an email to with the representative name and call reference number.

If the insurer that denied the claim is your secondary insurance and we don’t have your primary insurance on file:

  • Email with pictures of the front and back of your primary insurance card. We will then update your account and charges.
