CO 59 Denial Code - Multiple Procedure Adjustment
Code 59 indicates that the claim was processed according to rules for multiple or concurrent procedures. This typically affects claims where multiple surgeries, diagnostic imaging, or concurrent anesthesia services were billed together. The payer has applied their policy on how such services are reimbursed.
Who Pays: Group Code Liability
Typically, code 59 adjustments fall under CO, meaning the provider must write off the amount and cannot bill the patient. However, if the adjustment was due to a patient-specific situation, it might be PR, making the patient responsible for the additional amount.
Why Claims Get Code 59
- Multiple surgeries were billed on the same day, triggering a reduction per multiple procedure rules.
- Concurrent anesthesia services were not properly documented, leading to an adjustment.
- Diagnostic imaging services billed together were reduced per payer policy.
- Improper use of modifiers that indicate distinct services for multiple procedures.
- Misunderstanding of payer's specific rules about concurrent procedures.
How to Fix & Resubmit
- Review the claim to ensure that all procedures were billed with appropriate modifiers indicating multiple or distinct procedures.
- Check the payer's policy on multiple or concurrent procedures to understand the specific adjustments applied.
- If applicable, correct any coding errors and resubmit the claim with proper documentation supporting the services provided.
- Contact the payer for clarification if the adjustment seems incorrect or if the policy is not clear.
- If necessary, gather supporting documentation and submit an appeal if you believe the adjustment was incorrectly applied.
Corrected Claim or Appeal?
Submit a corrected claim if there were coding or documentation errors. If the adjustment is based on a misinterpretation of payer policy, consider submitting an appeal with supporting documentation.
Preventing Future 59 Denials
