N764 Remark Code - Missing Hematocrit Value Explanation
The N764 remark code indicates that the claim has a missing, incomplete, or invalid Hematocrit (HCT) value. This remark supplements the adjustment already noted by the accompanying reason code, providing further detail about why the claim has been adjusted or denied.
How It Relates to the Denial
N764 typically accompanies reason codes related to laboratory services or diagnostic tests where a Hematocrit value is required. The combination of this remark with an adjustment reason code signals that the HCT data is necessary for proper processing of the claim.
Common Scenarios
1A claim for a complete blood count (CBC) was submitted, but the remittance shows N764 along with a reason code for insufficient documentation.
→ This indicates that the claim was adjusted due to the absence or invalidity of the Hematocrit value, which is crucial for the billing of the laboratory test.
2An outpatient lab service claim was denied, and the remittance includes N764 alongside a reason code indicating a coding error.
→ The N764 remark suggests that the coding error is specifically related to the missing or incorrect Hematocrit value, which must be corrected for the claim to be processed.
3A physician's office billed for a lab test but received a remittance with N764 and an adjustment reason code indicating a lack of medical necessity.
→ In this case, the N764 remark clarifies that part of the issue is the missing or invalid HCT value, which the payer requires to substantiate medical necessity.
What to Do
