CLIA Lab Director and Consulting Services Compared
For the physician office lab or small lab that has added moderate or high complexity testing and needs a part-time CLIA lab director, a technical consultant or both. We read each firm's own service pages against the personnel rules in 42 CFR 493 Subpart M and CMS's director responsibilities brochure.
The verdict by use case
Best for a part-time director of record
It is the only firm here that publishes its directors' on-site schedule (typically once a quarter) and names the Subpart M path its directors qualify under.
Best for ongoing technical consultant coverage
Its service page lists the duties a technical consultant carries, from PT submissions and failure investigations to competency tracking, IQCP and calibration verification.
Best after a survey finds deficiencies
Clinical Lab Consultants (Ruiz & Associates)
Plans of correction with CMS, state agencies and accreditors are its core service, and its team includes a CAP inspector.

Service by service
Each row is something a part-time director or consultant takes off your hands, with the rule it answers to. A filled well means a dedicated service page describes it; a ring means the firm mentions it in passing; a blank well means we found nothing on the firm's site, not that the firm cannot do it.

What Subpart M asks of a director
A waived-only lab still needs a director, but CLIA sets no federal education or experience bar for that person. The bar arrives with the first moderate complexity test. From then on the director must meet § 493.1405, or § 493.1443 once any test is high complexity. A lab doing only provider-performed microscopy follows § 493.1357 instead. Every path below also needs a current state director license where the state issues one (paragraph (a) of each section).
| Route | Moderate complexity, § 493.1405 | High complexity, § 493.1443 |
|---|---|---|
| MD or DO licensed in your state, board-certified in anatomic or clinical pathology | Qualifies, (b)(1) | Qualifies, (b)(1) |
| MD, DO or DPM licensed in your state | At least 1 year directing or supervising nonwaived testing, plus 20 CE hours, (b)(2) | At least 2 years directing or supervising high complexity testing, plus 20 CE hours, (b)(2) |
| Earned doctoral degree in a laboratory science (or another doctorate with lab coursework or thesis) | HHS-approved board certification, 1 year directing or supervising, 20 CE hours, (b)(3) | HHS-approved board certification, at least 2 years of lab training or experience and of directing or supervising high complexity testing, 20 CE hours, (b)(3) |
| Master's degree | 1 year of training or experience, 1 year supervisory, 20 CE hours, (b)(4) | No path |
| Bachelor's degree | 2 years of training or experience, 2 years supervisory, 20 CE hours, (b)(5) | No path |
| Serving as director on December 28, 2024 | Qualifies if serving continuously since then, (b)(6) | Qualifies if serving continuously since then, (b)(4) |
These paths come from the December 2023 final rule, whose personnel changes took effect on December 28, 2024. A director who was serving on that date, and has served continuously since, is covered by the grandfather paragraph; anyone else must meet one of the paths. Ask which paragraph a candidate relies on.
What CMS is not enforcing today
In memo QSO-25-21-CLIA (23 June 2025) CMS told state survey agencies that a physician on the moderate (b)(2) path may have either the year of directing or supervising or the 20 CE hours, and that it will not require the additional 20 CE hours on the doctoral, master's and bachelor's moderate paths or on the high complexity physician and doctoral paths. The rule text has not changed; the CLIA lab director requirements guide explains the memo.
The visit rule for a moderate complexity director is one line: “Be onsite at least once every 6 months, with at least 4 months between the minimum two on-site visits” (§ 493.1407(c)(1)).
The same words sit in § 493.1445(c) for high complexity directors. The director must also document the visits, “including evidence of performing activities that are part of the laboratory director responsibilities”, and stay reachable by phone or electronically between them. “Each individual may direct no more than five laboratories.” CMS's director brochure adds that the cap counts nonwaived labs only, and that the same person may serve as technical consultant, technical supervisor or clinical consultant for any number of labs.
A part-time director may hand duties to a technical consultant or clinical consultant who meets their own qualifications, but “remains responsible for ensuring that all duties are properly performed” (§ 493.1407(b)), and the lab must specify each person's duties in writing (§ 493.1407(e)(14)). That is why a consulting contract matters as much as the director's CV.
Proposed, not law
CMS proposed new personnel qualification changes on October 8, 2026 (CMS-3478-P, 91 FR 64480), with comments due December 7, 2026. Until a final rule is published, the paths above are the ones a surveyor applies.
How to check a director's qualifications
A firm's word that its directors are “qualified” is not what a surveyor reads. CMS's director brochure tells directors to confirm qualifications, training and competency records for all personnel, and that includes the director's own file. Run these steps on any candidate, whoever supplies them.
- Name your highest complexity. One high complexity test puts the whole director role under § 493.1443, which has no master's or bachelor's path.
- Ask which paragraph, in writing. The candidate should name the exact path, such as “§ 493.1405(b)(2)”. A firm that cannot name it has not checked.
- Collect the evidence for that path. A medical license in your state for the MD, DO and DPM paths; the pathology board certificate for (b)(1); a current certificate from an HHS-approved board for the doctoral path (the rule says “certified and continue to be certified”); the diploma or transcript for degree paths; letters or records showing the years spent directing or supervising nonwaived testing (high complexity testing for § 493.1443); and CE certificates adding up to at least 20 hours on the director's duties.
- Check the state. Paragraph (a) of both sections requires a current state director license where the state issues one. Your CLIA state agency can tell you whether yours does.
- Test a grandfather claim. It holds only for someone qualified and serving as director of that complexity in a CLIA-certified lab on December 28, 2024, and continuously since. Ask for the CLIA number and the dates.
- Count their labs. Ask for the CLIA numbers of every nonwaived lab the person directs today, yours included. The limit is five.
- File the change. CMS tells labs to notify the State Agency or accreditor within 30 days of a change in laboratory director.
Short on CE hours? CMS points directors to CDC's free Laboratory Director University courses, which cover some of the duties; the CMS director page links them.

Takeaway
What the director agreement should say
None of the firm pages we read shows a sample agreement, so the terms are yours to write. The director stays responsible for everything the rule assigns, so the agreement should make each duty visible on paper. These are the clauses a part-time arrangement most often leaves vague.
- Visit dates and visit evidence. At least two on-site visits a year, at least 4 months apart, each leaving a signed record of what the director reviewed, as § 493.1407(c)(2) asks. A visit with no evidence of director work is a visit a surveyor cannot see.
- Reach between visits. How the lab reaches the director by phone or electronically, and how fast an answer comes when QC fails on a Saturday.
- Who does what, by name. Which duties go to a technical consultant or clinical consultant, who that person is, and the paragraph they qualify under. CMS says delegation must be in writing, and the director remains responsible.
- Review frequency. CMS notes that the regulations do not set how often the director reviews QC, PT and procedures: your SOP does. Put the same frequency in the agreement so the two match.
- PT ownership. Who enrolls the lab, who reviews each PT report and who signs the corrective action when an event is unsatisfactory. Our CAP vs API proficiency testing comparison covers the programs themselves.
- The lab count. A promise to tell you before taking on a lab that would exceed five.
- Notice to leave. Enough notice that you can find a successor and report the change within 30 days.
Competency sign-offs are where delegated duties most often go unrecorded (see what the competency rules ask); the competency assessment software comparison shows the tools that track them, and the inspection-readiness software comparison covers the ones that keep personnel files ready for a survey. On paper, our inspection checklist lists the records a surveyor pulls.
A director in name only
A director who signs the CMS-116 and never appears leaves the lab exposed: the duties in § 493.1407(e) still have to be done, and the visit records are the proof that they were.
How this comparison was made
We read each firm's own service, team and home pages; 42 CFR 493 Subpart M on eCFR; CMS's laboratory director page, director responsibilities brochure (May 2025) and HHS-approved certification boards list; and the October 2026 proposed rule in the Federal Register, last on .
A filled well means we verified the claim against a document we could read and link: the firm's own documentation or a regulator's record. An open ring means the firm says so in its own material, but we found no document to check it against. A blank well means we found nothing either way, which does not prove the product lacks it.
Verdicts are editorial: no organization can buy a verdict position or displace another. This page carries no prices and no ratings; ask each firm for its current fees and terms before you commit.
These are service firms, so a “document” here is a dedicated service page that says what the service does. A homepage line, a team biography or a menu label counts as stated. We left out directors who advertise as individuals rather than as a firm. State rules and accreditor checklists can ask more than CLIA, so check both before you sign.
Questions labs ask
Does a waived-only lab need a qualified lab director?
It needs a director, but CMS says there are no federal education or experience qualifications for the director of a lab with a Certificate of Waiver (CMS director page). The Subpart M paths start with the first moderate complexity test. Your state may set its own rules.
Can a part-time CLIA lab director work fully remotely?
No. A moderate or high complexity director must “be onsite at least once every 6 months, with at least 4 months between the minimum two on-site visits” and document those visits (§ 493.1407(c), § 493.1445(c)). Between visits the work can be remote, by phone or electronically.
How many labs can one director run?
“Each individual may direct no more than five laboratories” (§ 493.1407(d)). CMS's director brochure says the cap counts nonwaived labs only, and that the same person may be technical consultant, technical supervisor or clinical consultant for any number of labs.
Can the director also be our technical consultant?
Yes, if the director also meets that role's qualifications. The moderate complexity director “may function as the technical consultant” (§ 493.1411), and the high complexity director may act as technical supervisor on the same terms (§ 493.1449). Ask the firm whether its quote covers both roles.
Did CMS's October 2026 proposed rule change director qualifications?
Not yet. CMS-3478-P, published October 8, 2026, proposes changes to personnel qualifications, with comments due December 7, 2026 (91 FR 64480). It is a proposal; the current text of § 493.1405 and § 493.1443 still applies.
What do we file when the director changes?
Notify your State Agency or accreditor within 30 days of the change, as CMS's director brochure advises. Keep the new director's qualification evidence in the personnel file before the first day of directing.
