What is the corporate practice of medicine?

Definition
Medicine must be owned by licensed clinicians.
The corporate practice of medicine doctrine holds that medical decisions must be controlled by licensed clinicians rather than by lay owners or corporations. Arizona follows this doctrine, which is why a non-licensed medspa owner typically cannot directly own the entity that practises medicine — and why the MSO/PLLC structure exists.

This is the term that most often turns up late — usually when a non-clinician has already signed a lease, ordered equipment, and is trying to work out why their attorney keeps mentioning a second entity.

The underlying principle

The doctrine exists to keep clinical judgment insulated from commercial pressure. If a lay corporation could own a medical practice outright, it could in principle direct how many patients a clinician sees, which treatments get recommended, and how quickly a visit must conclude. The doctrine's answer is that medicine must be owned and controlled by people licensed to practise it.

Arizona follows this doctrine. It is a live constraint here, not a formality, and it shapes how nearly every non-clinician-owned medspa in the state is structured.

The MSO/PLLC structure

The standard solution separates the business from the medicine into two entities with a contract between them.

MSO (management company)PLLC (professional entity)
Who owns itAnyone, including non-licensed ownersA qualifying licensed clinician — physician or, in Arizona, typically an NP
What it ownsLease, equipment, brand, systemsThe medical practice itself
What it controlsBusiness operations, marketing, administrationAll clinical decisions
Who it employsNon-clinical staffClinical staff
RevenueManagement fee under a services agreementPatient revenue
What it must not doDirect clinical judgment

The management services agreement is the hinge of the whole arrangement. It must be genuine: a real fee for real services, set at a defensible value, without the management company acquiring effective control over clinical decisions. Agreements that nominally separate the two while functionally handing clinical control to the lay owner are the ones that attract scrutiny.

Where this goes wrong
The nominal medical director

The failure pattern is a clinician who lends their licence to the professional entity for a monthly fee, never sets foot in the practice, and exercises no real clinical authority. The structure looks right on paper and is hollow in substance. The clinician carries licensing exposure for a practice they do not oversee, and the owner is operating a medical practice without meaningful clinical control.

Why Arizona is comparatively favourable

Because Arizona grants NPs full practice authority, a qualifying NP can generally hold the professional entity. States that require a physician owner give practices a narrower and usually more expensive set of options.

For an RN or a non-clinician owner, this means the pool of people who can legitimately hold the clinical entity is wider here, and NP-led ownership is a well-established path rather than a workaround.

Where consulting ends and law begins

We will say plainly where our usefulness stops. Forming entities, drafting a management services agreement, and setting the management fee are legal and valuation questions for an Arizona healthcare attorney. An hour of that advice before you sign anything is the best money in the entire startup budget.

What we can do is the clinical half: making sure the practice inside the structure has a real medical director relationship, workable standing orders, a defensible delegation framework, and documented good-faith exams — so the substance matches what the paperwork claims.

Frequently asked

Can a non-licensed person own a medspa in Arizona?

They can own the business, but generally not the entity that practises medicine. The usual structure separates the two: a management company (MSO) owned by the lay owner handles the business side, while a professional entity (PLLC) owned by a qualifying licensed clinician holds the medical practice. The relationship between them is defined by a management services agreement.

What is an MSO?

A management services organization — a business entity that provides non-clinical services to a medical practice: premises, equipment, staffing for non-clinical roles, marketing, billing, and administration. It can be owned by anyone. What it cannot do is control clinical decisions.

Can an NP own the professional entity in Arizona?

Generally yes. Because Arizona grants NPs full practice authority under A.R.S. 32-1601, a qualifying NP can typically hold the professional entity rather than needing a physician owner. This is one of the most commercially significant features of practising in this state and a major reason NP-owned practices are common here.

What happens if the structure is wrong?

The consequences compound. Arrangements that improperly split clinical control can be unenforceable, can create licensing exposure for the clinician who lent their name, and can implicate fee-splitting and anti-kickback rules. Restructuring after the fact is substantially more expensive than setting it up correctly at the start.

Is this something a consultant can set up?

No, and you should be wary of anyone who says otherwise. Entity formation and management services agreements are legal work requiring an Arizona healthcare attorney. A consultant can help you understand the landscape and design the clinical operation that sits inside the structure, but drafting it is not consulting.

Structuring a practice you cannot legally own outright?

This is the point where a consultant should hand you to an attorney — and we will. What we can do is make sure the clinical side of the structure actually works once it is built.
