The Centers for Medicare & Medicaid Services and Centers for Disease Control and Prevention have issued a final rule updating proficiency testing and referral requirements under the Clinical Laboratory Improvement Amendments.
Provisions of the final rule are generally effective July 11, 2024; however, regulations related to laboratories performing tests of moderate complexity, as well as high complexity testing that also performs waived testing and proficiency testing enrollment, are effective Aug. 10, 2022. Additional information is available in a fact sheet.
