The short answer

Missouri's medical board is the State Board of Registration for the Healing Arts, which licenses physicians and physician assistants. In the board pages, statutes and rule we reviewed, we found no Missouri board statement on cosmetic injections. The statutes we read let physicians delegate treatment to nurses and physician assistants through written collaborative practice arrangements. Ask who authorizes your treatment, then verify each person's license with the board that issues it.

Who licenses injectors in Missouri, and the board name to know


Missouri's medical board is called the State Board of Registration for the Healing Arts. Despite the unfamiliar name, it is the board that licenses physicians. Its own page says it was created in 1939, administers the Healing Arts Practice Act, and protects the public by licensing physicians and other health designated professionals and investigating complaints against its licensees.

Nurses answer to a different body. The Missouri State Board of Nursing says its jurisdiction covers licensed practical nurses, registered professional nurses and advanced practice registered nurses, and that it has no jurisdiction over physicians. Estheticians are licensed by the Board of Cosmetology and Barber Examiners, which issues a license called Class E esthetician.

One practice can involve people licensed by different boards, so the spa's name tells you little. Check each person with the board that licenses that person.

What Missouri's sources say about Botox, and what they do not


Section 334.010 of the Healing Arts chapter makes it unlawful for anyone who is not a registered physician to practice medicine or surgery in Missouri, or to profess to cure and attempt to treat the sick, except as the chapter provides. The chapter then provides for physicians to work with nurses and physician assistants through written arrangements, covered below.

In the statutes and rule we read for this guide (RSMo 334.010, 334.104, 334.735 and 335.016, and 20 CSR 2200-4.200), we did not find Botox, neurotoxins or cosmetic injections named. We also found no position statement on cosmetic injections from the Board of Nursing: its position statements page lists two documents, one on patient abandonment and one responding to a court case.

That silence matters. This guide can describe the general rules about who may work under whose authority, but it cannot tell you that a particular cosmetic treatment is or is not allowed for a particular license type. For that question, ask the relevant board.

In the sources we read we also found no Missouri license for medical spas and no statute or rule setting medical director requirements. We did not search the full Missouri statutes and rules for these terms. The rules we found attach to individual licenses, so the checks below start with the person treating you.

APRNs and physician assistants: collaborative practice


RSMo 334.104 lets a physician enter collaborative practice arrangements with registered nurses. They must be written agreements, jointly agreed-upon protocols or standing orders, and they may delegate authority to administer or dispense drugs and provide treatment, provided the care is within the nurse's scope of practice and consistent with the nurse's skill, training and competence. For an advanced practice registered nurse (APRN), the statute also allows delegation of the authority to prescribe drugs.

The statute sets out what the written arrangement must contain. It must describe how the physician and APRN will collaborate, and it must require a disclosure statement posted at every office where the APRN is authorized to prescribe, telling patients they may be seen by an APRN and have the right to see the collaborating physician. It also requires the arrangement to provide that the APRN submits at least ten percent of charts to the collaborating physician, or another designated physician, for review every fourteen days. A physician may not collaborate with more than six full-time equivalent APRNs, physician assistants or assistant physicians in any combination, with exceptions the statute lists.

The joint rule, 20 CSR 2200-4.200, adds that the methods of treatment delegated must be within each professional's scope of practice and consistent with that person's skill, training, education and competence (for an APRN, also licensure and certification). It tells the collaborating physician to consider the nurse's skill, education, training and competence when deciding what to delegate.

Physician assistants are licensed through the Healing Arts board. RSMo 334.735 lists the services in a physician assistant's scope, including routine therapeutic procedures and other tasks, not prohibited by law, that the physician assistant has been trained and is proficient to perform under a collaborative practice arrangement. The statute says a physician assistant may not prescribe except under such an arrangement, may not practice without physician collaboration or where the collaborating physician is not immediately available for consultation, assistance and intervention (except as the section otherwise provides), and that the physician is responsible for oversight.

Section 334.104 also requires physicians to report to the Healing Arts board whether they are in a collaborative practice arrangement and the name of each licensed professional involved, and says the board shall make that information available to the public. The Board of Nursing says APRNs are not required to give it a copy of their collaborative practice agreement, so ask the practice who the collaborating physician is.

RNs and LPNs: administering what a prescriber orders


The Nursing Practice Act defines professional nursing to include the administration of medications and treatments as prescribed by a person licensed by a state regulatory board to prescribe medications and treatments. It defines practical nursing as care given under the direction of such a prescriber or of a registered professional nurse, and says that care may be delivered by a licensed practical nurse without direct physical oversight.

The decision tree the Board of Nursing publishes, adapted from an Ohio Board of Nursing tool, states that licensed nurses have ultimate accountability for the management and provision of nursing care, including all delegation decisions. It is a decision aid, not a Missouri rule about cosmetic procedures.

The Board of Nursing's complaint page also says medical assistants are not regulated in Missouri. If someone is introduced by that title, ask what license, if any, the person holds. Our guide to RN injector delegation rules compares how states handle the nurse question.

Estheticians: what the Missouri license covers


RSMo 329.010 defines the Class E esthetician license around massaging, cleansing, stimulating, manipulating, exercising, beautifying or similar work on the scalp, face, neck, ears, arms, hands, bust, torso, legs or feet, using mechanical or electrical appliances or cosmetic preparations, along with hair removal by means other than electric needle, and arching or tinting eyebrows or tinting eyelashes. The definition does not mention injections.

The Board of Cosmetology and Barber Examiners has published a Medical Esthetician Disclaimer. It says the board has no medical esthetician license and issues only Class E esthetician licenses, and that it is concerned the term may mislead consumers into believing the board has sanctioned advanced medical training. The page shows no date. See our guide to medical esthetician scope limits for the wider picture.

How to check a Missouri license


Missouri's licensee search runs on the state's MOPRO system. The page says it provides data from the licensing database that constitutes primary source verification, updated nightly, and that you must choose at least one criterion: county, profession, name or license number. It offers separate searches for active and non-active licensees, and its profession list includes physicians (MD and DO), physician assistants, assistant physicians and Class E estheticians.

The same page says the Board of Nursing does not use this search as its verification tool and points nurses' licenses to Nursys Licensure Quick Confirm. For an esthetician, the Cosmetology and Barber board says you may check the type and status of a license on its website or call it at (866) 762-9432.

Get the full name and license type from the practice first, then match the result to the person assigned to your appointment. Our license verification guide and consultation checklist can help you organize the rest.

How to file a complaint with the right board


Healing Arts board: its complaint page tells you to save or print the complaint form (a PDF), complete it, and email or mail it back using the details on the form's first page. The board's general inquiries block lists an enforcement office at 573.526.1105 and enforcement@pr.mo.gov.

Board of Nursing: the board does not collect verbal complaints. It accepts a paper complaint form by mail, fax or email, or an online portal complaint, and says complaints must be in writing. The board says anyone may file a complaint against the license of a registered professional nurse or licensed practical nurse. A complaint about a physician belongs with the Healing Arts board instead.

Board of Cosmetology and Barber Examiners: its Consumer Complaint Guide says the board can investigate only complaints alleging violations of Chapters 328 or 329 of the Missouri statutes, and that complaints must be in writing and signed by the person filing. See our complaint guide for what to gather before you write.

A license check is only one part of the decision

A license lookup does not evaluate a clinician's technique or whether a procedure is right for you. Ask about experience with your proposed treatment, assessment, products, aftercare and follow-up, and discuss suitability with the licensed professional who evaluates you.

Frequently asked questions

Who can inject Botox in Missouri?

In the board pages and statutes we reviewed, we found no Missouri board statement that names who may inject Botox. The sources we read show physicians, and APRNs, RNs and physician assistants working under written collaborative practice arrangements or prescriber orders, within their skill, training and competence. Verify the specific person and ask who authorizes your treatment.

Can a nurse inject Botox in Missouri?

Missouri's nursing definitions include administering treatments as prescribed by a licensed prescriber, and RSMo 334.104 lets physicians enter written collaborative practice arrangements with registered nurses and APRNs. Licensed practical nurses are described as giving care under a prescriber's or RN's direction. In the pages we reviewed, we found no Board of Nursing statement on cosmetic injections, so confirm the license.

Can an esthetician do Botox in Missouri?

The Missouri statute defining Class E estheticians lists massage, cleansing, hair removal and similar work, and does not mention injections. The cosmetology board says it issues only Class E esthetician licenses and has no medical esthetician license. Ask the practice who is licensed to treat you and verify that license.

Does a Missouri med spa need a medical director?

In the statutes and rule we read, we found no Missouri license for medical spas and no medical director requirement; we did not search all Missouri statutes and rules for these terms. The rules we found attach to individual licenses, such as collaborative practice arrangements between physicians and nurses. Ask the practice which physician is involved in your care and verify that physician's license.

How do I look up a Missouri physician or nurse license?

Use the state's MOPRO licensee search for physicians, physician assistants and estheticians, choosing a county, profession, name or license number. The Board of Nursing does not use that tool; its licensee page points to Nursys Licensure Quick Confirm for nurses. Match the result to the person assigned to your appointment.

Why is Missouri's medical board called the Board of Registration for the Healing Arts?

The board's own page says it was created in 1939 and administers the Healing Arts Practice Act. Its mission covers licensing physicians and other health designated professionals and investigating complaints against its licensees. In practice it is the board to contact about a physician's license.
