Wiki Pathology & Laboratories - QW modifier

[agongora1]

Can you please define the QW modifier (besides that it's a Clinical Laboratories Improvement Act) & who can bill for these test? If a doctor (Family Practice doctor) is a CLIA certified can he bill for these test with the QW appended??? Or is this for Laboratories & Pathology ONLY???
Example: If pt comes in to the Family Practice office to have (CLIA) lab work done ONLY & the office collects the specimen & sends it to the laboratory. Can the Famliy Practice doctor bill for those labs? with the QW modifier appended?

If it is sent to the lab then you should only bill for the drawing. If the patient comes in and does a urinalysis by dip stick you would bill 81003 with the QW modifier and the CLIA number in box 23 of the hcfa.

It also depends on the level of CLIA certification your office has to which test you can do in office
