If your menu includes a single prescription treatment, yes, you need a physician involved, whatever the statute calls the role. Few states require a “medical director” by that name. Every state requires a prescriber to evaluate the patient and order neurotoxin, filler, GLP-1 or IV therapy, and every injection your nurses give on that order needs a physician, or a nurse practitioner where the state allows, to delegate it.
The prescription is the requirement
Federal law sets the floor. A prescription drug may be dispensed only “upon a written prescription of a practitioner licensed by law to administer such drug” (21 U.S.C. 353(b)(1)). Neurotoxins, semaglutide and tirzepatide, and the medications added to an IV bag all sit on the prescription side of that line.
Nursing licenses are built around that order. Florida’s definition is typical: professional nursing includes administering medications and treatments “as prescribed or authorized by a duly licensed practitioner.” An RN injector, however skilled, carries out an order. The RN does not write it.
So the real question for your clinic is who examines each patient, who writes each order, and who delegates the work to your staff. That person is your medical director in practice, whether or not a statute uses the title. The good faith exam is where that relationship starts.
Some states do use the title
A handful of states name the role and attach duties to it. As of October 2026:
Florida. A business licensed as a health care clinic under Chapter 400, Part X must “appoint a medical director or clinic director who shall agree in writing to accept legal responsibility” for a list of activities: signage, practitioner licensure, records, adverse incident reporting and billing review (Fla. Stat. 400.9935(1)). Section 400.9905(5) defines the medical director as a physician licensed under chapter 458, 459, 460 or 461. A clinic director who is not a physician is allowed only where the clinic provides no services under those physician practice acts, which rules it out for an injectables menu.
Tennessee. Tenn. Code Ann. 63-6-105 created a public online registry of medical spas, in force since January 1, 2016. The board rule requires the name and Tennessee license number of the “medical director or supervising physician,” who must be an MD or DO with an active Tennessee license and an active Tennessee practice, and who attests to responsibility for the spa (Tenn. Comp. R. & Regs. 0880-02-.24). The Tennessee registry post covers who falls inside the definition.
Texas. The cosmetic rules speak of a “delegating physician.” Before a delegated cosmetic procedure, 22 TAC 169.26(c) requires the physician, or a PA or APRN acting under the physician’s delegation, to establish a practitioner-patient relationship. For elective IV therapy outside a physician’s office or licensed facility, Occupations Code chapter 172, added by H.B. 3749 effective September 1, 2025, lets a physician delegate ordering to a PA or APRN and administration to a PA, APRN or RN, each “acting under adequate physician supervision.”
Most other states reach the same place through delegation rules. The state-by-state medical director hub sets out all fifty-two jurisdictions with sources.
When your menu needs a physician
| If your menu includes | Physician involvement you need | Why |
|---|---|---|
| Neurotoxin or dermal filler | A prescriber’s exam and order for each patient, plus a delegating physician if RNs inject | Neurotoxin is a prescription drug; nurses act on an order |
| GLP-1 or other prescription weight loss | A prescriber who examines, orders and monitors | Prescription drug, with follow-up the prescriber owns |
| IV therapy with any added medication | A prescriber’s order and a physician who delegates and supervises | Texas ch. 172 names physician supervision outright; elsewhere the order rule applies |
| Hormone therapy or peptides on prescription | A prescriber’s exam, order and lab review | Prescription drug |
| Lasers, microneedling, chemical peels | Depends on state device and delegation rules; often a physician delegates | Classified as medical acts in many states; check yours |
| Facials, waxing, nonmedical skin care | Usually none | Cosmetology or esthetics license governs |
If even one row above the last describes your clinic, plan for a physician. One exception narrows it: in states that grant nurse practitioners independent prescribing, such as Arizona (A.R.S. 32-1601), an NP may examine and order within scope without a physician. Whether that NP may then delegate to your RNs is a separate question with state-specific answers.
A real director versus a name on paper
The North Carolina Medical Board published a disciplinary lesson built on the pattern operators are sold most often. A physician agreed to serve as medical director of a med spa owned by an entrepreneur with no medical training. He was told the role required no hours on site and no involvement in procedures. NPs and PAs delivered the care. After a PA’s laser facial left a patient with burns, he learned he was listed as the supervising physician for all four of them. For four months, the only contact had been his monthly payment.
The board’s conclusion: a physician who accepts such a role “may be aiding and abetting the unlicensed practice of medicine in North Carolina.” The case study walks through it.
A director who is doing the job leaves evidence:
- Written protocols for every service on your menu, revised when the menu changes.
- Delegation records naming each person supervised and what each may do.
- A good faith exam and order before each patient’s first treatment.
- Chart review on a set schedule, documented.
- A named physician reachable during treatment hours, and a named backup.
- An adverse event pathway the staff can recite.
MDside’s position is narrower than much of the market. A physician who signs and never appears leaves you exposed along with the physician, because the paperwork asserts supervision that is not happening.
How a medical director sees patients
Sometimes personally, always through the chart. Texas requires the relationship to be established by the physician, or a PA or APRN under delegation, before the delegated act, and requires the physician or a designee to be onsite or “immediately available for emergency consultation” (22 TAC 169.26(d)). Florida’s clinic director duties under 400.9935 are mostly legal and administrative. In practice, the director sees patients when examining, when a complication arises, and when a case falls outside protocol.
What this means for you
List every treatment on your menu and mark each one that involves a prescription drug, an injection or a device your state treats as medical. If any are marked, you need a physician who examines or oversees the exam, writes or authorizes the orders, and delegates in writing to your staff. Check whether your state also names the role, as Florida does for licensed clinics and Tennessee does through its registry. Then hire someone who will do the work in the list above. MDside supplies the physicians, the good faith exams and the protocols for med spas and IV therapy programs.

Frequently asked questions
Do I need a medical director for Botox?
You need a prescriber who evaluates the patient and orders the neurotoxin, because it is a prescription drug. If an RN injects, you also need a physician, or an NP where the state permits, to delegate the injection. Texas, for example, requires the practitioner-patient relationship to be established before a delegated cosmetic procedure, with the physician onsite or immediately available.
Do you need a medical director for IV therapy?
If the bag contains any prescription medication, a prescriber must order it and someone with authority must delegate administration. Texas made this explicit in 2025: Occupations Code chapter 172 lets a physician delegate elective IV therapy to a PA, APRN or RN, each acting under adequate physician supervision. Other states reach the same result through prescription and delegation rules.
Who can be a medical director for a med spa?
Usually a physician, MD or DO, licensed in the state where patients are treated. Tennessee requires an MD or DO with an active Tennessee license and practice. Florida defines a licensed clinic’s medical director as a physician under its physician practice acts. No state cited here requires dermatology or plastic surgery. In full practice states, an NP may examine and order independently.
Does a medical director have to see every patient?
Not necessarily in person. A prescriber must evaluate each patient before treatment, and that may be the director or another authorized practitioner under the director’s protocols. The director owns the protocols, delegation, chart review and complications. Texas requires the physician or a designee to be onsite or immediately available for emergency consultation during delegated cosmetic procedures.
