Certificate for Provider-performed Microscopy (PPM)

6006.3 – Certificate for Provider-performed Microscopy (PPM) Procedures (Rev. 230; Issued: 07-11-25; Effective: 07-11-25; Implementation: 07-11-25) A Certificate for Provider-performed Microscopy (PPM) procedures is issued to a laboratory in which a licensed physician, midlevel practitioner, or dentist performs only the microscopy tests listed at 42 CFR 493.19(c) or performs only the listed microscopy tests in any combination with waived tests during a patient’s visit. A certificate for PPM procedures is valid for a 2-year period. Upon certificate expiration, and after payment of appropriate fees, the laboratory’s certificate will be renewed for another 2-year period. The laboratory that holds a PPM certificate is subject to quality system requirements for nonwaived tests. However, such a laboratory is not routinely inspected but may be included in an inspection sample of non-waived laboratories or a complaint investigation by SA surveyors or CMS.
