CLINICAL LABORATORY FEE SCHEDULE UPDATE
INDUSTRY NEWS TAGS: CMS
CMS is updating the status of two codes on the Clinical Laboratory Fee Schedule (CLFS).
• Effective immediately, code G0431QW is deleted from the CLFS. Code G0431 describes a high complexity test, and should not be reported with a QW modifier; the QW modifier indicates a CLIA waived test.
• Effective immediately, code G0434QW is added to the CLFS. Code G0434 can describe a CLIA waived test. The use of the QW modifier to indicate a CLIA waived test is necessary for accurate claims processing.
Codes G0431 and G0434 will remain on the CLFS.
