This Change Request (CR) will communicate the latest tests approved by the Food and Drug Administration (FDA) as waived tests under the Clinical Laboratory Improvement Amendments of 1988 (CLIA). These test codes will be incorporated into the Clinical Laboratory Fee Schedule with a QW modifer so that they can be billed by facilities with a CLIA certificate at the appropriate level.
