Does anyone know when I need to add the Q4 modifier to lab tests? Our office recently received denials from commerical payers that stated they did not recoginize the modifier (Q4). I tried to contact our medicare carrier but they could not answer and sent my question to another tier. I did find this descprition on line:
A Q4 modifier is required for accurate claims processing of laboratory, radiology, and ultrasound interpretations by any provider other than the attending physician.
Is this the best description of this modifier?
