Modifier policy updated for commercial plans only


We have included the modifier “QW” to our current modifier policy for commercial plans only. This modifier is used to identify Clinical Laboratory Improvement Amendment (CLIA)-waived test(s). If this modifier is used in claims submissions that are not CLIA-waived tests, those claims will be denied. Please note, claims for CLIA-waived tests need to include both the modifier and CLIA number. Here’s the Modifier Reference Policy (Commercial) for more details.
