N464Remark Code (RARC)Active
N464 Remark Code - Incomplete/Invalid Support Data
The N464 remark code indicates that the claim was denied due to incomplete or invalid support data. This means that the information provided with the claim was insufficient for processing, which may include missing documentation or errors in the data submitted.
How It Relates to the Denial
The N464 code typically accompanies adjustment reason codes that highlight issues with the claim's supporting documentation. The combination of these codes signals to the biller that additional review or correction is needed regarding the data provided for the claim.
Common Scenarios
1A facility billed for a surgical procedure but received a denial with the N464 remark code indicating issues with the documentation provided.
→ This suggests that the payer found the supporting documentation inadequate, possibly due to missing pre-authorization or incomplete operative notes.
2A provider submitted a claim for a consultation but got a remittance with the N464 remark code alongside a reason code for insufficient documentation.
→ Here, the remark indicates that the payer could not process the claim because the required documentation was either not provided or was deemed invalid.
3A claim for physical therapy services was submitted, but the remittance returned included the N464 code indicating invalid support data.
→ This implies that the documentation supporting the medical necessity for therapy was either incomplete or incorrectly formatted.
What to Do

What to Check
