Physician Office Lab CLIA Requirements and Checklist
A physician office lab (POL) needs a CLIA certificate for its most complex test: Waiver, Provider-Performed Microscopy, Compliance or Accreditation. Nonwaived POLs must meet CLIA rules for personnel, proficiency testing, quality control, procedures and competency. They are surveyed every two years by the state agency or an approved accreditor.

Key facts and official sources
In August 2026, 116,613 of 300,720 CLIA-registered labs, or 38.78%, were physician offices (CMS CLIA statistics).
Non-exempt POLs by certificate type:
Waiver: 84,524
Provider-Performed Microscopy: 16,232
Compliance: 9,117
Accreditation: 4,258
Each lab location generally needs its own CLIA application, with limited exceptions (42 CFR 493.35).
Moderate complexity requirements are in 42 CFR 493 Subparts H, J, K and M.
Which CLIA certificate does a physician office lab need?
Certificate of Waiver: You only perform waived tests (§493.15)
Provider-Performed Microscopy (PPM): A physician, midlevel practitioner or dentist performs certain microscopy procedures during the patient visit (§493.19), with or without waived tests
Certificate of Compliance: You perform moderate or high complexity testing and the state agency surveys you
Certificate of Accreditation: You perform nonwaived testing and an approved accreditor such as COLA, CAP or The Joint Commission surveys you
Apply with Form CMS-116 through your state agency. Adding a nonwaived analyzer to a waived lab requires a certificate change before patient testing begins.
What is on the POL compliance checklist?
Certificate and fees: the certificate is current, matches your test menu and lists the correct director.
Qualified lab director: meets §493.1405, visits on site at least once every 6 months with at least 4 months between visits, and documents those visits (§493.1407(c)). One person may direct no more than five labs.
Technical consultant: qualified under §493.1411 and actively performing the §493.1413 duties.
Proficiency testing: enrolled for every regulated analyte. PT samples are tested like patient samples and never referred to another lab.
Quality control: run at the required frequency, reviewed, with documented corrective action.
Method verification: completed before patient testing on every new nonwaived test system (§493.1253).
Procedure manual: current SOPs, approved and signed by the director.
Training and competency: all six elements, twice in the first year and annually after that.
Records: retained for at least two years (§493.1105).
Can the physician owner be the lab director?
Often, yes. A licensed MD or DO can qualify as a moderate complexity director through board certification in pathology, or through laboratory experience or training plus continuing education under §493.1405. Being the practice owner does not by itself qualify someone. See lab director requirements.
What gets physician office labs cited?
The most common problems are failed or missed proficiency testing, lab director duties not carried out or not documented, gaps in QC and corrective action records, and missing competency assessments. Director oversight is a CMS focus: in its 2026 proposed rule, CMS wrote that "laboratory director citations remain among the top ten condition-level deficiencies cited by laboratory surveyors."
COLA or state survey for a POL?
Both are valid. See our neutral comparison: COLA vs CAP vs Joint Commission vs state survey.
Frequently asked questions
Do we need a technical consultant if the physician is the director?
Moderate complexity labs must have a qualified technical consultant. The director can fill that role if they meet the §493.1411 requirements.
Does a waived POL get inspected?
CMS or its agents can inspect Certificate of Waiver labs, announced or unannounced (§493.15(e)), but there is no routine two-year survey.
How often do POLs do proficiency testing?
For regulated analytes, enrolled labs typically receive three PT events a year. Each PT event has to be passed.
Can we test in more than one office under one certificate?
Usually not. Each location needs its own certificate unless a §493.35(b) exception applies, such as mobile or temporary testing sites.
