The Centers for Medicare & Medicaid Services (CMS) is updating the status of two codes on the Clinical Laboratory Fee Schedule (CLFS).
* Effective April 1, 2011, 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 April 1, 2011, 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. --------------------------------------------------------------------------------- Note: If you have problems accessing any hyperlink in this message, please copy and paste the URL into your Internet browser.
