Clinical Laboratory Improvement Amendments of 1998 (CLIA) requires that a laboratory be appropriately certified for each test it performs. The CPT codes that CMS considers to be laboratory tests under CLIA (and thus requiring certification) change each year.
Listed below are the latest tests approved by the Food and Drug Administration (FDA) as waived tests under CLIA. The CPT codes for the following new tests must have the modifier QW to be recognized as a waived test. However, CPT codes 81002, 81025, 82270, 82272, 82962, 83026, 84830, 85013 and 85651 do not require a QW modifier to be recognized as a waived test.
