Impact of prior payer(s) adjudication including payments and/or adjustments

What Does This Code Mean?

This adjustment reflects amounts already paid or adjusted by a prior payer in a coordination-of-benefits scenario; it is informational rather than a new denial.

Common Causes

  • Secondary payer processing after primary payer already paid
  • Claim correctly following COB sequencing

Recommended Next Steps

  1. Confirm the primary payer's EOB/835 matches what's reflected here
  2. No action typically needed if COB sequencing is correct
  3. Investigate only if the secondary payment doesn't reconcile with expectations
