Secondary payment cannot be considered without primary payer's identity/payment info

What Does This Code Mean?

Informational remark used with COB denials — the secondary payer needs the primary payer’s EOB/payment details before it can process the claim.

Common Causes

  • Primary payer's EOB not attached or referenced
  • COB fields left blank on the secondary claim

Recommended Next Steps

  1. Attach the primary payer's EOB/835 information to the secondary claim
  2. Resubmit once complete COB data is included
