OA-195: Refund to Erroneous Priority Payer
The payer priority is being corrected. Submit the claim to the correct primary payer and update COB records.
What Does OA-195 Mean?
With OA (Other Adjustments), this is the standard group code for payer priority corrections. The adjustment reflects a coordination of benefits correction — the payment is being redirected to the correct payer. Submit the claim to the correct primary payer and update COB records.
CARC 195 appears when a coordination of benefits error is corrected. The claim was initially processed and paid by the wrong payer in the priority sequence — for example, Medicare paid as primary when another payer should have been primary, or the secondary payer was treated as the primary. This code reflects the adjustment made to correct the payment order.
This is common in Medicare Secondary Payer (MSP) situations where Medicare was incorrectly billed as the primary payer when another insurer (employer group health plan, auto insurance, workers compensation, etc.) should have paid first. It also occurs when retroactive coverage changes alter the payer priority order.
Common Causes
| Cause | Frequency |
|---|---|
| Payment originally sent to wrong priority payer The claim was initially processed and paid by the wrong payer in the priority sequence, and a refund is being issued to correct the payment order | Most Common |
| Coordination of benefits error corrected A coordination of benefits error was identified where the wrong payer was treated as primary, and the adjustment reflects the correction | Most Common |
| Retroactive coverage change affecting payer priority A retroactive change in the patient's coverage (such as a new primary insurance being identified) changed the payer priority order, requiring a refund to the erroneous payer | Common |
| Medicare Secondary Payer (MSP) correction Medicare was incorrectly treated as the primary payer when another payer should have been primary under MSP rules, and the refund corrects this | Common |
How to Resolve
- Review the COB correction Understand the corrected payer priority order from the remittance.
- Submit to the correct primary payer File the claim with the payer that should be primary.
- Update patient records Correct the patient's COB information for future claims.
- Appeal if the original order was correct If the original payer priority was accurate, submit COB documentation and enrollment records proving the correct order.
Appeal if you believe the original payer priority was correct. Include documentation showing the correct coordination of benefits order, such as the patient's insurance enrollment records and MSP determination if applicable.
Common RARC Pairings
The RARC code tells you exactly what triggered the OA-195:
| RARC | Description |
|---|---|
| N130 | You may need to review plan documents or guidelines Review the payer priority determination and submit the claim to the correct primary payer → |
| MA04 | Secondary payment cannot be considered without primary payer information Submit the primary payer's EOB with the claim to the correct secondary payer → |
How to Prevent OA-195
- Verify coordination of benefits and payer priority order before submitting claims
- Update patient insurance information regularly to reflect current coverage and priority
- For Medicare patients, verify MSP status before billing Medicare as primary
- Respond promptly to COB questionnaires from payers to maintain accurate priority records
- Use real-time eligibility verification to confirm the correct primary payer
