What is Denial Code N639

Remark code N639 indicates that reimbursement has been processed in accordance with the fee schedule specific to inpatient rehabilitation facilities.

Common Causes of RARC N639

Common causes of code N639 are incorrect billing for services that should be aligned with the inpatient rehabilitation facilities (IRF) fee schedule, misclassification of the type of healthcare facility or services provided, and errors in the application of the IRF fee schedule to the billed services.

Ways to Mitigate Denial Code N639

Ways to mitigate code N639 include implementing a comprehensive review process for all claims before submission to ensure that the services billed align with the correct facility type and fee schedule. Training staff on the specific billing requirements and fee schedules for inpatient rehabilitation facilities can help avoid mismatches. Additionally, utilizing advanced billing software that automatically flags potential discrepancies based on the type of facility and the services rendered can prevent this issue. Regular audits of billing practices and feedback loops for continuous improvement can also reduce the occurrence of this code.

How to Address Denial Code N639

The steps to address code N639 involve several key actions to ensure proper handling and follow-up. First, review the payment received against the inpatient rehabilitation facilities (IRF) fee schedule to confirm accuracy. If discrepancies are found, prepare a detailed comparison highlighting the differences. Next, gather all relevant documentation, including the initial claim, the IRF fee schedule applicable at the time of service, and any supporting medical records or authorization letters. Then, if an underpayment is identified, submit an appeal to the payer with all supporting documents and a clear explanation of the discrepancy. In the case of an overpayment, assess the need to issue a refund to the payer, following their guidelines for overpayment return. Throughout this process, maintain detailed records of all communications and documents submitted for future reference. Finally, review internal billing practices to ensure future claims align with the IRF fee schedule, adjusting processes as necessary to prevent similar issues.
