Allowance of QW modifier on codes U0002 and 87635

Issue
Effective for dates of service on and after March 2, 2020, CMS added the QW modifier (Clinical Laboratory Improvement Amendments Act [CLIA] waived tests) to procedure codes 87635 and U0002. However, the Common Working File (CWF) wasn’t updated to accommodate this request. A recent update has been made to the system.
Resolution
Claims impacted will be reprocessed for dates of service on and after March 2, 2020, that were denied when the QW modifier was reported on 87635 and U0002.
