M42 Remark Code: Physician Signature Required
The M42 remark code indicates that the attending physician must personally sign the medical necessity form for the claim to be processed appropriately. This remark serves to clarify that a signature issue is affecting the claim's approval, as noted by the accompanying reason code.
How It Relates to the Denial
The M42 remark code typically accompanies adjustment reason codes that relate to issues with medical necessity documentation. This combination signals that a claim denial or adjustment is tied to incomplete or improperly signed forms related to medical necessity.
Common Scenarios

3A diagnostic test was performed, but the claim was adjusted with a reason code for medical necessity issues, accompanied by the M42 remark.
