Remark code N81 indicates that the procedure billed does not align with the tooth surface code provided. This discrepancy suggests that the dental procedure code and the tooth surface area code submitted on the claim form do not match accepted billing practices or payer-specific guidelines. It may require a review of the claim to ensure that the correct codes are used that accurately reflect the services provided.
Common causes of code N81 are:
1. Incorrect or mismatched entry of procedure codes and tooth surface codes on the dental claim form.
2. Use of a procedure code that does not logically correspond with the tooth surface area reported.
3. Inadvertent selection of a tooth surface code that is not applicable for the procedure performed.
4. Outdated or obsolete procedure codes that no longer align with current coding standards for tooth surfaces.
5. Data entry errors or typos when inputting the procedure or tooth surface codes into the billing system.
6. Lack of understanding of the specific coding guidelines for dental procedures and tooth surface designations.
7. Failure to update the billing system with the latest dental procedure codes and compatible tooth surface codes.
Ways to mitigate code N81 include ensuring accurate and consistent dental coding practices. This involves verifying that the procedure codes entered on claims match the appropriate tooth surface codes as per the American Dental Association's (ADA) Current Dental Terminology (CDT). Regular training for coding staff on updates to dental codes and payer-specific guidelines can help maintain compliance. Additionally, implementing a robust pre-claim adjudication process with dental coding software that cross-references procedure codes with tooth surface codes can catch discrepancies before submission. It's also beneficial to conduct periodic audits of dental claims to identify and address any patterns of coding errors that could lead to this remark code.
The steps to address code N81 involve reviewing the dental procedure code and the associated tooth surface code submitted on the claim. First, verify the accuracy of the procedure code by checking the patient's treatment records and ensuring it matches the service that was performed. Next, cross-reference the tooth surface code to confirm it is appropriate for the reported procedure. If a discrepancy is found, correct the codes on the claim form. If the codes are accurate, provide additional documentation to support the compatibility of the procedure with the tooth surface code, and resubmit the claim. If necessary, consult with the dental coder or billing specialist to ensure the correct codes are used for future submissions.
