CO 159 Denial Code - Terrorism Service Adjustment
Code 159 indicates that the service or procedure provided was a result of a terrorism-related incident. This adjustment code reflects the payer's categorization of the claim based on the nature of the event causing the medical need.
Who Pays: Group Code Liability
Code 159 works like other benefit exclusions: the group code on the remittance controls liability. PR-159 puts the charges on the patient and permits billing; CO-159 requires a provider write-off under contract terms. Some plans coordinate terrorism-related claims with government or victim-compensation programs, so confirm whether an alternate payer exists before sending the balance to the patient.
Why Claims Get Code 159
- The medical service was directly related to injuries or conditions caused by a terrorism event.
- The claim was submitted with documentation indicating a terrorism-related cause of injury.
- The payer identified the service as related to a terrorism incident based on external data or reports.
How to Fix & Resubmit
- Verify the documentation supporting the terrorism-related cause of the service.
- Contact the payer to confirm if additional information is needed or if the adjustment is final.
- Check if the payer has specific guidelines or exceptions for terrorism-related claims.
- If applicable, submit a corrected claim with the necessary documentation.
- If the adjustment seems incorrect, prepare to appeal with evidence supporting the non-terrorism nature of the service.
Corrected Claim or Appeal?
If code 159 is applied incorrectly, a formal appeal with supporting documentation may be necessary. Corrected claims are appropriate if initial documentation was incomplete or incorrect.
Preventing Future 159 Denials
- Ensure all claims clearly document the cause of injury or service necessity to avoid misclassification.
- Stay updated on payer policies regarding terrorism-related claims.
- Train staff to recognize and properly code claims related to unusual events like terrorism.
- Implement a checklist for claim documentation to ensure completeness before submission.
