Remark code N843 indicates a claim issue due to a missing, incomplete, or invalid Core-Based Statistical Area (CBSA) code.
Remark code N843 indicates that there is an issue with the Core-Based Statistical Area (CBSA) code in the submitted claim. Specifically, the CBSA code is either missing, incomplete, or invalid, which needs to be addressed for proper claim processing.
Common causes of code N843 are incorrect or missing entries in the billing system for the Core-Based Statistical Area (CBSA) code, data entry errors when inputting the CBSA code, outdated software that does not include the most current CBSA codes or fails to prompt for this information, and lack of staff training on the importance of including accurate geographic information in billing submissions. Additionally, this code can be triggered by a mismatch between the CBSA code provided and the geographic location associated with the service provided, often due to administrative oversight or confusion regarding the correct CBSA code for a specific service location.
Ways to mitigate code N843 include ensuring that the billing team is thoroughly trained on the importance and specifics of Core-Based Statistical Area (CBSA) codes. Implement a double-check system where claims are reviewed for completeness and accuracy of CBSA codes before submission. Utilize updated billing software that includes automatic prompts or checks for CBSA codes based on the service location. Regularly audit billing records to identify and correct recurring issues with CBSA code errors. Establish a clear communication channel with clinicians and service location administrators to ensure that the most current and accurate location information is available for billing purposes.
The steps to address code N843 involve a multi-faceted approach to ensure the correct Core-Based Statistical Area (CBSA) code is provided, which is crucial for accurate billing and reimbursement processes. Initially, it's essential to verify the patient's address and cross-reference it with the most current CBSA codes available through the Office of Management and Budget (OMB) or the Centers for Medicare & Medicaid Services (CMS), as these agencies periodically update CBSA codes.
Next, engage with your coding team or utilize coding software to ensure that the correct CBSA code is applied based on the patient's address. This may involve training or re-training staff on the importance of geographic codes in billing and how to locate and apply the correct CBSA codes.
If the claim was denied due to an incorrect CBSA code, correct the code on the claim based on the verified patient address and resubmit the claim as soon as possible. It's also beneficial to implement a system of checks and balances within your billing software to flag claims with missing or potentially incorrect CBSA codes before submission. This preemptive measure can significantly reduce the occurrence of N843 codes and streamline the billing process.
Lastly, consider maintaining an updated database of CBSA codes within your electronic health record (EHR) or practice management system. This database should be reviewed and updated regularly to reflect any changes made by the OMB or CMS. By integrating this database with your patient registration process, you can automate the assignment of CBSA codes based on patient addresses, thereby minimizing human error and ensuring that claims are submitted with the correct information the first time.
