Remark code N644 indicates payment was adjusted following the bilateral procedure rule, affecting reimbursement amounts.
Remark code N644 indicates that reimbursement has been made in accordance with the bilateral procedure rule, which typically applies to procedures performed on both sides of the body during the same operative session.
Common causes of code N644 are incorrect billing for procedures that should be billed under the bilateral procedure rule, failure to apply the bilateral procedure rule when both sides are treated during the same operative session, and misinterpretation of the payer's guidelines regarding bilateral procedures.
Ways to mitigate code N644 include implementing a robust pre-claim review process that ensures the accuracy and appropriateness of coding for procedures that could be subject to the bilateral procedure rule. This involves training coding staff on the nuances of bilateral procedures and regularly updating them on changes in coding standards and payer policies. Utilizing advanced coding software that flags potential bilateral procedures before submission can also help in identifying and correcting coding errors proactively. Additionally, conducting periodic audits of claims related to bilateral procedures can help identify patterns of errors or misunderstandings, allowing for targeted education and process improvements. Engaging in clear communication with surgeons and proceduralists to understand the intent and scope of the procedures performed can also aid in accurate coding and documentation, thereby reducing the likelihood of receiving code N644.
The steps to address code N644 involve several key actions to ensure proper handling and potential reevaluation of the claim. First, review the claim to confirm that the procedure billed was indeed subject to the bilateral procedure rule and that billing was done correctly according to this rule. If the billing was accurate, no further action is required. However, if the procedure was not bilateral or if there was an error in how the bilateral procedure was billed, prepare and submit a corrected claim with detailed documentation to justify the adjustment. This may include operative reports or physician notes clarifying the nature of the procedure. Additionally, it's important to audit similar claims to identify if there has been a systematic issue in how bilateral procedures are being coded and billed in your practice. If a pattern of errors is found, implement a corrective action plan to prevent future occurrences of this issue. Lastly, consider providing additional training or resources to the billing staff on the correct application of the bilateral procedure rule to ensure compliance and maximize reimbursement.
