Summary Statement of Deficiencies D5219 EVALUATION OF PROFICIENCY TESTING PERFORMANCE CFR(s): 493.1236(c)(2) At least twice annually, the laboratory must verify the accuracy of any test or procedure listed in subpart I of this part for which compatible proficiency testing samples are not offered by a CMS-approved proficiency testing program. This STANDARD is not met as evidenced by: Through a review of the Proficiency Testing policy, a review of documentation of the laboratory's proficiency testing, and interviews with laboratory staff, it was determined the laboratory failed to follow their written procedures for Proficiency Testing and failed to verify the accuracy of the frozen section histopathology at least twice annually. Survey findings include: A. The Proficiency Testing policy states, "Proficiency Testing in the Mohs Micrographic Cutaneous Oncology, this laboratory has instituted an External Quality Control Program. Semi-annually, the tech or Risk Manager will send two cases containing the original slides, label it with only the surgical case number, and send it out for a microscopic examination by a Board Certified Dermatolpathologist." B. A review of documentation labeled "Quality assurance, proficiency testing" revealed the external quality control samples were submitted once in 2018 (dated June 2018), once in 2019 (dated 5/20/2019), and once in 2020 (dated 2/9/2020) instead of twice annually as required. C. During an interview at 10:20 on 3/10/2020, laboratory employee #2 (as listed on the form CMS-209) confirmed the proficiency testing was documented annually.
