Q4 Modifier

    Default Q4 Modifier

    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?


  2. Default Q4 modifier
    I know this questions was asked over 3 years ago, but it has now come up in our clinic. Does anyone know when this modifier is to be used on lab codes? I see the modifier is still an active modifier, but what does the description refer to "Svc exempt?

    Thank you for assistance with this.

    I use the Q4 modifier on my claims to signify that they are the donor's claim for transplants. I have no idea if this helps you
