N402Remark Code (RARC)Active
N402 Remark Code - Incomplete Periodontal Charting
The N402 remark code indicates that the periodontal charting submitted with the claim is either incomplete or invalid. This remark supplements a Claim Adjustment Reason Code that already details the adjustment related to this issue, providing further clarification on the specific nature of the problem with the documentation.
How It Relates to the Denial
Typically, the N402 remark accompanies adjustment reason codes that relate to denied claims for dental services, particularly those involving periodontal procedures. The combination signals that the payer found issues with the charting documentation required for proper processing.
Common Scenarios
1A dental provider submitted a claim for scaling and root planing but received a denial indicating insufficient documentation.
→ In this case, the N402 remark points to the periodontal charting as being incomplete or invalid, suggesting the provider needs to review the submitted documentation to ensure it meets payer requirements.
2A claim for periodontal maintenance was denied, and the remittance included a reason code for insufficient information along with the N402 remark.
→ The N402 remark indicates that the periodontal charting provided does not meet the necessary standards, reinforcing the need for more comprehensive documentation before resubmitting the claim.
3A dentist billed for a periodontal procedure and received a denial with an adjustment reason for improper documentation and the N402 remark attached.
→ The presence of the N402 remark highlights that the issue lies specifically with the periodontal charting, which the payer found lacking or incorrect.
