How to open a med spa in Missouri

1. Can you own a med spa?

Who is allowed to own the business, and in what corporate form?

Missouri’s Professional Corporation Law restricts WHO MAY HOLD SHARES. A professional corporation may issue shares, fractional shares, rights or options to purchase shares, and other securities only to natural persons authorized by law — in Missouri or another US jurisdiction — to render a professional service permitted by the corporation’s articles of incorporation, and to trustees of revocable trusts on the conditions the section sets out. The Law defines a “disqualified person” to reach not only individuals but corporations, partnerships, limited liability companies, fiduciaries, trusts, associations, governmental agencies and other entities that are or become ineligible to own shares. These claims survey sections 356.011 to 356.261 and do not report on restrictions elsewhere in Missouri law.

2. The medical oversight you will need

Which physician relationship the state requires, and what they must do.

⛔ MISSOURI FIXES THE SUPERVISION BURDEN IN NUMBERS, AND IT COUNTS CHARTS. A physician may enter collaborative practice arrangements with registered professional nurses, in the form of written agreements, jointly agreed-upon protocols or standing orders, and those arrangements may delegate authority to administer or dispense drugs and provide treatment — but only within the nurse’s scope of practice and consistent with that nurse’s skill, training and competence. The statute then fixes the review burden in numbers: the APRN must submit at least TEN PERCENT of the charts documenting their delivery of health care services for physician review EVERY FOURTEEN DAYS, and the collaborating physician must review every fourteen days at least TWENTY PERCENT of the charts in which the APRN prescribes controlled substances. Where the arrangement covers diagnosis and initiation of treatment for acutely or chronically ill or injured persons, the collaborating physician must be present for sufficient periods of time at least once every two weeks. Geographic proximity is required, subject to the exceptions the section itself sets out. Separately, delegating professional responsibilities to a person not qualified by training, skill, competency, age, experience or licensure is a ground for discipline. On the cosmetology side the licensed practice is enumerated: the Class E esthetician occupation is defined by a list of manual and apparatus-based skin practices, with cosmetic preparations not to exceed ten percent phenol.

3. What has to happen before a patient is treated

The exam or provider-patient relationship required before the first injection.

⛔ MISSOURI ANSWERS THE ONLINE-INTAKE QUESTION DIRECTLY, AND THE ANSWER IS CONDITIONAL. A physician using telemedicine must ensure a properly established physician-patient relationship exists, and the statute names the three ways it may be established: an in-person encounter through a medical evaluation and physical examination; consultation with another physician who has an established relationship with the patient and an agreement to participate in that patient’s care; or a telemedicine encounter, IF the standard of care does not require an in-person encounter. To establish the relationship through telemedicine the technology must be sufficient to reach an informed diagnosis as though the evaluation, and any physical examination the standard of care requires, had been performed in person. A questionnaire — internet or telephone — must be reviewed by the treating health care professional and must itself carry information sufficient to serve as though the medical evaluation had been performed in person; otherwise the statute says in terms that it DOES NOT constitute an acceptable medical evaluation and examination for providing treatment by telehealth. Before prescribing through telemedicine or the internet, the physician must obtain a reliable medical history and, if the standard of care requires, perform a physical examination adequate to establish the diagnosis and identify underlying conditions or contraindications.

4. Who may actually inject

Whether an RN, NP, or PA may treat, and under whose supervision.

An advanced practice registered nurse in Missouri is a person licensed under the nursing chapter to practice advanced practice nursing as a certified clinical nurse specialist, certified nurse midwife, certified nurse practitioner or certified registered nurse anesthetist. PRESCRIBING RUNS THROUGH THE WRITTEN ARRANGEMENT ON THE FACE OF THESE CLAIMS: a collaborative practice arrangement MAY delegate to an APRN the authority to administer, dispense or prescribe drugs and provide treatment, and may delegate authority over controlled substances in Schedules III, IV and V and Schedule II hydrocodone. The delegation runs through the written arrangement described in the supervision section of this reference; whether any independent route exists elsewhere in the nursing chapter is not surveyed by these claims. PHYSICIAN ASSISTANTS are bounded differently again: the statute enumerates their scope of practice as consisting ONLY of nine listed services and procedures, and says a physician assistant may not prescribe any drug, medicine, device or therapy except pursuant to a collaborative practice arrangement.

5. What it costs — the part that is a legal question

We do not publish build-out cost estimates. Fit-out, equipment, lease and staffing are real costs and they are not regulatory monitoring — any figure we gave you would be someone else’s estimate with our name on it. What we can tell you, cited, is which of Missouri’s requirements are also spending decisions, because those are the ones that are not optional and the ones with dates attached.

• The physician relationship

  Whatever the state requires here is a recurring cost, not a one-off — a medical director or delegating physician is a paid relationship for as long as you operate.

  "Class E - estheticians" includes the use of mechanical, electrical apparatuses or appliances, or by the use of cosmetic preparations, antiseptics, tonics, lotions or creams, not to exceed ten percent phenol, engages for compensation, either directly or indirectly, in any one, or any combination, of the following practices: massaging, cleansing, stimulating, manipulating, exercising, beautifying or similar work upon the scalp, face, neck, ears, arms, hands, bust, torso, legs or feet and removing superfluous hair by means other than electric needle or any other means of arching or tinting eyebrows or tinting eyelashes, of any person.

• Registering the facility

  Where a state requires the premises itself to be registered or licensed, that is a filing with a timetable — and a date you can miss.

  ⛔ MISSOURI ALLOWS COMPOUNDED STOCK AHEAD OF THE ORDER AND TIES IT TO A RELATIONSHIP THAT ALREADY EXISTS, WHICH IS WHERE COMPOUNDED SEMAGLUTIDE FOR A NEW CLINIC FAILS. Pharmacists may compound preparations in limited quantities prior to receiving a valid prescription based on a history of receiving valid prescriptions that have been generated solely with an established pharmacist/patient/ prescriber relationship. The justification is a history of real prescriptions inside an established pharmacist/patient/prescriber relationship — not projected demand, and not a clinic’s intention to sell.

• The corporate structure

  The entity the state permits you to trade through determines what you pay to form and maintain it, and sometimes who has to be on the paperwork.

  A professional corporation may issue shares, fractional shares, rights or options to purchase shares, and other securities only to natural persons who are authorized by law in this state, or in any other state or territory of the United States or the District of Columbia, to render a professional service permitted by the articles of incorporation of the corporation, and trustees, in trust, of revocable trust agreements, of which the trustee is a natural person who is authorized by the law of this state, or any other state or territory of the United States or the District of Columbia, to render a professional service permitted by the articles of incorporation of the corporation.

6. What you can put in the syringe

GLP-1 and peptide legality is federal and moves independently of Missourilaw — a compounded product can lose its basis nationwide with no change to your state’s rules. Check current standing before you build a service line around one.

Does a med spa have to register or hold a license in Missouri?

⛔ WHAT THESE CLAIMS ESTABLISH IS PERSON AND SCHOOL LICENSURE, AND — under the Board of Cosmetology and Barber Examiners’ own fee rule — PREMISES LICENSURE TOO: 20 CSR 2085-3.010(2)(C) prices a cosmetology establishment of up to three operators at $100 to license and $75 to renew, and separately prices opening one without registering first. The Board of Cosmetology and Barber Examiners exists for the purpose of licensing all persons engaged in the practice of cosmetology, manicuring, esthetics and barbering, and a school of cosmetology must obtain a license from the board before opening. The chapter defines a “cosmetology establishment” as that part of any building wherein any of the classified occupations are practiced, including space rented within a licensed establishment, and gives the board power to prescribe by rule for the INSPECTION of cosmetology establishments and schools and their sanitary conditions — but no claim on record here states a statutory establishment license, so a Missouri operator should confirm the premises requirement with the board or counsel. The apprenticeship route is set by hours per occupation: no less than three thousand hours for cosmetologists, eight hundred for manicurists and fifteen hundred for esthetics.

What can a med spa advertise in Missouri?

Three subparagraphs of Missouri’s omnibus discipline ground — misconduct, fraud, misrepresentation, dishonesty, unethical conduct or unprofessional conduct in the performance of the functions or duties of any profession licensed or regulated by CHAPTER 334 — bear directly on how a med spa sells: misrepresenting that any disease, ailment or infirmity can be CURED by a method, procedure, treatment, medicine or device; obtaining or attempting to obtain any fee, charge, tuition or other compensation by fraud, deception or misrepresentation, including willfully and continually overcharging or overtreating patients or charging for visits that did not occur; and attempting, directly or indirectly, by intimidation, coercion or deception, to obtain or retain a patient or to discourage the use of a second opinion or consultation. Outside the board, the Merchandising Practices Act declares deception, fraud, false pretense, false promise, misrepresentation, unfair practice or the concealment, suppression or omission of any material fact in connection with the sale or advertisement of merchandise an unlawful practice, and the ATTORNEY GENERAL may seek an injunction in circuit court against it.

What happens if a med spa in Missouri operates without the right license or supervision?

It is unlawful in Missouri for any person not a registered physician to practice medicine or surgery in any of its departments, to profess to cure and attempt to treat the sick and others afflicted with bodily or mental infirmities, or to engage in the practice of medicine across state lines, except as the chapter provides. The board’s omnibus ground reaches misconduct, fraud, misrepresentation, dishonesty, unethical conduct and unprofessional conduct in performing the functions or duties of a regulated profession, and the enumerated examples include willfully and continually performing inappropriate or unnecessary treatment, diagnostic tests or medical or surgical services, and performing or prescribing medical services the board has declared by rule to be of no medical or osteopathic value.
