Reply To: Using a QW modifier with CPT code 85018

[Missouri Public Health Association]

Are any of you getting paid for CLIA services? If so, are you doing anything different than what I’m doing? I have been instructed to put our CLIA number in box 23 and use the QW modifier in order to get CLIA services paid. But we are still getting denied. I have had a case study done, and UHC says “incorrect qualifier G1 submitted in Loop 2300”. I can’t find where to change my qualifier. Whatever it is, I have no idea what it is or how to change it. I am waiting for my provider relations advocate (Leslie Kenedy) to get back from vacation. In the meantime, I am not billing CLIA services.
