OA-192: Non-Standard Adjustment Code from Paper Remittance

What Does OA-192 Mean?

With OA (Other Adjustments), this is the typical group code for CARC 192 since it relates to coordination of benefits. The adjustment from the primary payer's paper EOB needs to be properly mapped and the claim resubmitted to the secondary payer.

CARC 192 is a technical code used in coordination of benefits (COB) transactions when the primary payer issued a paper remittance (not an electronic ERA) and the adjustment reason on that paper EOB cannot be reasonably mapped to an existing standard CARC. This code serves as a catch-all placeholder in the 837 COB transaction.

This code is not a clinical or coverage denial — it is an administrative artifact of converting paper remittance information into electronic format. The actual adjustment reason from the primary payer is on the paper EOB, and the secondary payer or billing team needs to review that original document to understand the real reason for the adjustment.

How to Resolve

1. Review the primary payer's paper EOB Identify the actual adjustment and map it to the correct standard CARC.
2. Resubmit to the secondary payer Submit the corrected claim with the properly mapped code and the primary payer's EOB.
