📖 Detailed Explanation
RARC Code N115 (Alert: Submit appropriate documentation) is a Remittance Advice Remark Code maintained by X12 as part of the standardized code set required for HIPAA-compliant electronic healthcare transactions. While CARC (Claim Adjustment Reason Codes) explain WHY a claim was adjusted, RARC codes provide supplemental information about HOW to resolve issues, what actions to take, or alert you to important processing details. This particular code is an "Alert" type RARC, meaning it's providing you with important informational context about the claim processing. Alert codes typically don't require immediate corrective action but give you valuable information for understanding the adjudication or for future claim submissions. Pay attention to these alerts as they can help you avoid future denials and improve your billing practices.
