It is the first question almost every operator asks, usually because someone has offered them a cheaper arrangement. The short answer: in most states, no — and in the states where it is technically possible, it is rarely the structure that survives growth.
Who may hold the role, by state
| State | May a nurse practitioner be the medical director? |
|---|---|
| Texas | No. MD or DO only. NPs and PAs may deliver care under delegation but cannot hold the role. |
| New York | No. Only a physician licensed under Education Law Art. 131 may own the entity practicing medicine. |
| California | No. The professional medical corporation is physician-owned; the director is an MD or DO. |
| Georgia | No. The delegating role belongs to a physician; an APRN practices under a nurse protocol agreement. |
| New Jersey | No. The professional corporation is physician-owned and governed. |
| Tennessee | No. The registry requires a Tennessee-licensed MD or DO as medical director or supervising physician. |
| Florida | No. An active, unencumbered Florida MD or DO. |
| Illinois | Narrow exception — an APRN meeting the state’s full-practice-authority threshold may own the clinical entity. The physician route is the one that travels. |
| Arizona | Fewest supervision requirements of the states we cover. Operators still use physicians, for reasons below. |
Seven of nine: unambiguous no. That is not an accident of drafting. The medical director role exists to place clinical responsibility with the license that carries the broadest scope and the deepest accountability.
Two different jobs, often confused
| Medical director (MD or DO) | Nurse practitioner or PA | |
|---|---|---|
| Approves protocols and standing orders | Yes — this is the core of the role | Works within them |
| Delegates medical acts to other licenses | Yes | Generally no |
| Owns the clinical standard for the practice | Yes | No |
| Treats patients | Yes | Yes, within their own license |
| Answers to the medical board for the practice | Yes, personally | Answers to their own board for their own practice |
This is why “our NP can be the medical director” is usually a category error rather than a cost saving. An excellent nurse practitioner delivering excellent care is not the same thing as the person who signs the protocol that authorizes the whole clinic.
Why the cheaper arrangement gets expensive
- It does not travel. A structure built on advanced-practice independence has no valid clinical entity in the majority of states. Multi-state expansion is where this surfaces, usually after a lease is signed.
- Counterparties override statute. Malpractice carriers, device manufacturers, pharmacies, landlords and payers write their own requirements, and many of them require a named physician whatever the state permits.
- Scope creep. Menus grow. The service you add next year may be one only a physician can authorize, and by then the structure is load-bearing.
- Defensibility. After an adverse event the question is who was clinically responsible and what they actually did. A named physician, a signed protocol and a documented review is a materially stronger answer.
What MDside is
MDside is a physician network. We place licensed MDs and DOs as medical directors and behind the clinical decisions on our platform. Your nurse practitioners, physician assistants and nurses are your clinical team, and they practice within their own licenses under the protocols our physicians approve. We are not a substitute for your staff; we are the clinical authority above them that most states require and every insurer prefers.

Frequently asked questions
Can a nurse practitioner be a medical director?
In most states, no. Texas, California, New York, Georgia, New Jersey, Tennessee and Florida all require an MD or DO in the role. Illinois has a narrow exception and Arizona imposes the fewest requirements.
Can an NP own a med spa?
In a small number of states, yes. In most, the entity delivering medical services must be physician-owned, with a separate management company for everything that is not the practice of medicine.
Is an NP-led clinic cheaper to run?
On the monthly fee, sometimes. Across a multi-state footprint, an insurance renewal or an adverse event, it is usually the more expensive structure.
Do we have to replace our nurse practitioners?
No, and you should not. This is about who holds clinical authority over the practice, not about who delivers care. Your team keeps treating patients.
What does a medical director actually do?
Approves protocols and standing orders, delegates within each license’s scope, stays available at the standard the state sets, reviews charts on a defined cadence, and responds to adverse events. The full description is here.
