Wiki QW modifier

[tajna.chagorski@taskforcebpo.com]

What is required modifier(s) for dipstick urinalysis, non-automated, without microscopy performed in a physician office for a Medicare patient?
81002-QW
I need explanation for modifier QW.
When it should be used and when it should not be used?
Thanks

You would use -QW if the device you are using is "CLIA-waived" AND your facility has a CLIA certificate allowing you to perform CLIA-waived testing

The practice only utilizes QW for approved CMS Waived testing and nothing else. Here are some CMS.gov links: https://www.cms.gov/Outreach-and-Ed...-MLN/MLNMattersArticles/downloads/MM10055.pdf. I hope this helps.
