Ordering Authority
A physician of record authorizes which panels your clinic orders and for whom.
Longevity Diagnostics
Find a Medical Director for Longevity Diagnostics Programs
Even a program that is just lab draws still needs a physician’s name behind it — someone ordering the panel, reviewing the result and following up when something comes back abnormal. That is oversight your clinic cannot skip by calling it diagnostics instead of treatment.
Medical Director Oversight
What a Director Actually Signs Off for Longevity Diagnostics
Each of these is a decision your director owns, in writing, before it happens in your clinic.
Result Review
Every panel reviewed by a licensed clinician, not routed straight to the patient with no read on what it means.
Abnormal-Finding Follow-Up
A documented path for what happens when a result comes back outside range, with timelines attached.
Referral Criteria
Findings that need a specialist leave your clinic on a defined pathway, not a verbal suggestion.
What We Set Up

A named physician of record for ordering and result review
Abnormal-result follow-up protocol, with escalation timelines
Body-composition tracking integrated into the same review cadence

Questions About Longevity Diagnostics
Still not sure? Twenty minutes on the phone answers what a page can't.
Does a Lab-Only Program Need a Medical Director?
Yes. Ordering labs, reviewing results and following up on abnormal findings is the practice of medicine even when nothing is prescribed. “Just lab draws” is not oversight-free.
Who Reviews the Results?
Your physician of record, on a documented cadence — not a dashboard the patient reads alone.
What Happens With an Abnormal Result?
Your protocol defines the escalation and follow-up timeline before the first panel is ever drawn, so nothing waits on someone noticing.
Does Body-Composition Tracking Need the Same Oversight as Lab Panels?
Yes — it runs through the same review cadence as the rest of your diagnostics menu, tied to the same physician of record rather than treated as a separate, unsupervised add-on.
Can We Offer Diagnostics Without Offering Any Treatment?
Yes — a diagnostics-only menu is workable, but it still needs a named physician of record ordering and reviewing results, not just a lab partnership with no clinical oversight attached.
Who Is Allowed to Own a Diagnostics Business?
Can a non-physician own a diagnostics-focused longevity clinic? The business, yes — the ordering and interpretation of labs, no. Clinics sometimes assume that because nothing is being prescribed, oversight is optional. It is not: ordering and reviewing labs is itself the practice of medicine.
That is what the corporate practice of medicine doctrine decides — and it is the single rule that shapes how your business is built. Most states hold that medical judgment belongs to licensed clinicians, so a non-physician or a general corporation may not own or control an entity that practices medicine. The MSO model is the answer the industry settled on.
The Rule
CPOM — Corporate Practice of Medicine
A doctrine in state law, not a company or a service. The professional entity — the PC — must be owned by a licensed physician, and control counts as much as ownership: who hires the clinicians, who sets the fees, who decides what gets treated.
Only a licensed physician may own the professional entity in most states
Control counts too — hiring clinicians, setting fees, directing treatment
Fee-splitting rules limit how the MSO can be paid
Enforcement is by medical boards, attorneys general, insurers and acquirers
The Structure
MSO — Management Services Organization
The company that provides everything a Diagnostics clinic needs that is not the practice of medicine, under a written management services agreement with the PC. You can own the MSO outright, whatever your license.
Owned by you, whatever your license — no physician equity required
Holds the brand, lease, staff, systems, supply and marketing
Paid a fair-market management fee, never a cut of clinical revenue
Takes no part in diagnosis, treatment or any clinical decision
How the two meet: a physician-owned PC employs the clinical team and holds the medical decisions; your MSO holds the brand, the lease, the staff, the systems and the supply; a fair-market management fee moves between them; and the line is drawn in writing where your state says it must be. A diagnostics-only menu still needs a documented reviewer of record — that gap is the one we see most often at intake.

Where the Money Actually Goes
What This Covers
How money actually moves through a PC/MSO structure — patient revenue landing in the PC, the fixed management transfer to the MSO, MedGrid's retainer, and physician compensation — the same CPOM flow of funds covered on this page, walked through step by step.
This isn't just how we recommend running the accounts. In a state that enforces corporate practice of medicine, this exact flow is required to keep a PC structure compliant: revenue lands in the PC first, the MSO is paid a fixed, fair-market amount rather than a share of medical revenue, MedGrid is paid a fixed retainer by the MSO, and the accounts stay separate.
It's also why MedGrid only builds on a PC — never a PLLC — in every state we work in. A PLLC lets revenue flow straight into a member's account with no equivalent separation, which is exactly the structure this flow of funds is built to avoid. Why that distinction matters.

Four Ways Diagnostics Clinics Get Structured Badly
These are the arrangements we most often find in place when a clinic comes to us, usually built in good faith, on advice from someone who had not read the state's rules.
An LLC That Should Be a PC
The clinical entity was formed as a plain LLC owned by a non-physician. In a strict state that is the whole problem, and it usually surfaces at diligence or renewal.
A Director on a Handshake
A physician agreed to "be the medical director" with no management agreement, no delegation document and no standing orders. There is nothing to show a board.
A Fee That Looks Like a Split
The MSO takes a percentage of clinical revenue. Many states read that as fee-splitting regardless of what the contract calls it.
Protocols From a Course
Treatment protocols copied from a training weekend, never adapted to this state or signed by the director who is supposed to own them.
