modifier QW
Hi,
I am knowing that modifier is use for waiwed CLIA test, and 87081 is not on a waived CLIA test. So if you want to bill 87081, you should not use QW modifier. Other way, if you use modifier QW, you must have the correct CLIA number on the claim to be bill.
This is the sample of some laboratory and pathology that show on Medical Services Aministration (MSA)
Waived CLIA Test Codes: 81002, 81003QW, 81025, 82465QW, 82947QW, 84703QW, 85013,
85014QW, and 85018QW
Physician Performed Microscopy Procedure Codes: 81000, 81001, and 81015
CLIA Certificate of Compliance/Accreditation Codes: 82948, 85660, 87077, 87081, 87205, 87207,
87210 and 87270.
NOTE: Modifier QW designates the procedure as a waived CLIA test.
Good luck
