When the Line Gets Crossed

Board Actions Against Functional Coaches, RNs, and Social Workers for the Unlicensed Practice of Medicine in Texas, California, New York, and Florida

A Clinical & Regulatory Briefing  |  www.yoonhangkim.com  |  April 2026

Why This Question Matters Now

The functional and integrative medicine space has exploded into a crowded marketplace where the title on the door does not always match the license behind it. Nurses, health coaches, social workers, and wellness entrepreneurs are building root-cause practices, interpreting labs, drafting supplement and hormone protocols, and marketing themselves directly to patients who are frustrated with conventional care. Most are trying to do good work. Some are drifting, often unknowingly, into territory that every state medical practice act reserves for licensed physicians.

The practical question is not whether state boards can act against non-physicians who cross that line. They can. The more useful question is how often they actually do, what conduct reliably triggers them, and how the enforcement patterns differ across Texas, California, New York, and Florida—four states that together shape most of the functional and integrative medicine market in the United States. This briefing pulls the relevant statutes, agencies, and representative cases into one place, with an emphasis on what physicians, nurses, coaches, and clinic owners should actually do with the information.

What Counts as the Practice of Medicine

Every state defines the practice of medicine in broadly similar terms: diagnosing, treating, prescribing, or operating for disease or injury—and holding oneself out as qualified to do so. Non-physicians typically enter the enforcement zone through one of four doors. The first is diagnosing, whether phrased as a formal ICD code or as a root-cause label like adrenal fatigue, leaky gut, methylation dysfunction, or chronic Lyme. The second is prescribing or directing regulated therapies, including IV infusions, bioidentical hormones, compounded peptides, chelation, and high-dose supplement protocols tied to disease claims. The third is title misuse, such as calling oneself a functional medicine doctor or practitioner in a way that implies physician licensure. The fourth—and often overlooked—is structural: owning, directing, or financially benefiting from a clinic that is functionally being run as a medical practice by non-licensed hands.

Coaches, RNs, and social workers who stay in education, lifestyle counseling, wellness coaching, and general nutrition information rarely draw board attention. Those who move into individualized diagnosis and treatment, especially when lab interpretation or prescribed substances are involved, become visible to regulators—particularly when a patient is harmed, a competitor complains, or an advertisement overreaches.

Texas

Statutory framework

Texas Occupations Code §155.001 is blunt: a person may not practice medicine in Texas unless that person holds a license issued by the Texas Medical Board. Section 164.052 separately prohibits any licensed physician from aiding or abetting an unlicensed person, partnership, or corporation in the practice of medicine. The Texas Medical Board and the Texas Attorney General share authority to issue cease-and-desist orders, pursue civil penalties, and refer matters for criminal prosecution. Unlicensed practice can be charged as a state jail felony or a third-degree felony depending on the harm caused.

How enforcement actually unfolds

Texas enforcement analysts at ByrdAdatto and other health law firms have observed that the Texas Medical Board rarely opens an investigation on ownership grounds alone. Instead, the board typically starts with a patient-safety complaint, and once it is inside a clinic, it layers on allegations of unlicensed practice, aiding and abetting, and corporate practice of medicine violations. The result is that non-physicians most often land in the board's sights through a clinical event, not a structural audit.

Representative cases

The Jenifer Cleveland matter is the clearest recent example. A mother of four from Fairfield, Texas, died in July 2023 after receiving an IV treatment at a med spa where the infusion was administered by the non-licensed owner. The Texas Medical Board moved quickly to suspend the clinic's medical director, Frisco anesthesiologist Dr. Michael Gallagher, and the case catalyzed broader scrutiny of med spa oversight across the state. The Cleveland death illustrates the pattern cleanly: a non-physician was delivering a regulated medical therapy, a patient was harmed, and the board reached both the unlicensed individual (through cease-and-desist and criminal referral pathways) and the physician whose license had provided the legal cover.

A second published Texas Medical Board matter involved a physician acting as medical director of a med spa where staff were placing hormone pellets (which the board characterized as surgery) and performing vaginal rejuvenation without an onsite physician and without independent licensure to do so. The board filed allegations under Rule 193 delegation requirements, aiding and abetting the unlicensed practice of medicine, and unprofessional conduct. Separately, the Texas Medical Board has pursued non-physicians performing laser treatments without physician delegation as a straight unlicensed practice complaint.

The Texas takeaway for functional practitioners is that the highest-risk configurations are IV clinics, hormone and pellet programs, and any setup in which an RN, LVN, or unlicensed staff member is functionally driving the treatment plan while a physician's name is on the door. The Texas Board of Nursing's Position Statement 15.11 makes clear that even when a delegated medical act is performed by an RN or LVN, the nurse cannot diagnose or prescribe, and the nurse remains personally accountable to nursing standards.

California

Statutory framework

California Business and Professions Code §2052 criminalizes practicing, attempting to practice, or holding oneself out as practicing any system of treating illness without a valid license. Section 2400 layers on the corporate practice of medicine prohibition, barring corporations and other artificial entities from holding professional rights or influencing a physician's medical judgment. Section 2053 separately makes it a felony to cause serious bodily injury while engaged in unlicensed practice. Unlicensed practice is a wobbler that can be charged as a misdemeanor or felony, with fines up to $50,000 and potential prison exposure.

How enforcement actually unfolds

The Medical Board of California investigates unlicensed practice through its own enforcement unit and routinely publishes accusations and decisions involving both non-physicians and the physicians who enabled them. California's corporate practice doctrine is among the most aggressive in the country: the board treats decisions about which patients are accepted, what tests are ordered, what treatments are offered, how records are maintained, and which supplies are purchased as medical decisions that cannot be made or influenced by non-physicians, including by management service organizations.

Representative cases

The Pure Med Spa matter is instructive. The Medical Board of California brought an action against William J. Wolfenden, Jr., M.D., alleging that he aided and abetted the unlicensed practice of medicine by allowing unlicensed persons and entities to control patient medical records, order and maintain drugs and biologicals, and maintain a public perception that the Pure Med Spa clinics were lawfully operated. A central figure in the case, identified as Herbert Kollinger, was presented to the public as Dr. Kollinger despite having no medical license from the Medical Board of California. The case is a textbook illustration of how the board reaches both the non-physician (through unlicensed practice allegations) and the physician (through aiding-and-abetting charges) when a clinic's operational reality diverges from its paper structure.

In Khan v. Medical Board of California, the court upheld physician discipline where the licensee had employed unlicensed persons and advertised them as licensed professionals, reinforcing that California will discipline physicians who enable unlicensed individuals to function in clinical roles even when the physician is not personally delivering the care. For functional coaches and unlicensed wellness professionals, California's appetite is real but triggered: the board typically moves when there is title misuse, patient harm, or a physician on the license who is being used as a shield rather than a clinician.

California is also distinctive in that a nurse cannot independently open and operate a medical spa; because a med spa is considered a medical practice, only a licensed physician or physician-owned professional corporation can own one. Assembly Bill 890, effective January 2023, has begun to expand independent practice authority for qualifying nurse practitioners, and from 2026 forward certain NPs may serve as medical directors, but this does not extend to RNs, health coaches, or social workers operating independently.

Florida

Statutory framework

Florida regulates the practice of medicine under Chapter 458 of the Florida Statutes and separately regulates dietetics and nutrition under the Dietetics and Nutrition Practice Act. The Florida Department of Health's Medical Quality Assurance division investigates both licensed practitioners and unlicensed individuals who are holding themselves out as qualified to diagnose or treat. Unlicensed practice of a regulated health profession in Florida can be charged as a first-degree misdemeanor, punishable by up to a year in jail and $1,000 in fines per offense—and escalates to a felony when the unlicensed activity results in serious bodily injury.

Representative case: Heather Kokesch Del Castillo

The Del Castillo matter is the most widely discussed Florida case involving a non-physician wellness practitioner and, notably, it did not involve any allegation of patient harm. Heather Kokesch Del Castillo was a privately certified holistic health coach who moved from California to Fort Walton Beach after her Air Force husband was transferred. She operated a business called Constitution Nutrition, offering individualized dietary coaching to paying clients. After a licensed dietitian complained to the Florida Department of Health, an investigator conducted a sting operation and served Del Castillo with a cease-and-desist order along with $754 in fines and investigative fees. Del Castillo had never represented herself as a licensed dietitian or nutritionist.

Represented by the Institute for Justice, Del Castillo sued, arguing that Florida's Dietetics and Nutrition Practice Act violated her First Amendment right to give individualized dietary advice for compensation. The U.S. District Court for the Northern District of Florida ruled against her. The Eleventh Circuit affirmed in February 2022, holding that the statute is a professional regulation with only an incidental effect on protected speech. The U.S. Supreme Court declined to take the case in December 2022. Florida did narrow the statute in 2020 to allow unlicensed individuals to provide nutrition advice to clients who are not under a physician's care for a disease or medical condition requiring nutrition intervention, but the core licensing requirement remains intact.

The Del Castillo case is important because it shows that Florida will enforce unlicensed practice statutes against a wellness coach even in the absence of patient harm, that a competitor complaint is enough to trigger enforcement, and that First Amendment defenses have failed at every level of the federal appellate system. For a Florida-based functional coach who interprets labs, drafts elimination diets for clients with diagnosed chronic illness, or pairs nutrition advice with supplement protocols, the exposure is concrete rather than theoretical.

New York

Statutory framework

New York divides professional discipline along an unusual line. The Office of Professional Medical Conduct within the New York State Department of Health investigates and prosecutes physicians, physician assistants, and specialist assistants. Every other licensed health profession—including nurses, social workers, mental health counselors, dietitians, and dentists—is regulated by the New York State Education Department's Office of the Professions and its Office of Professional Discipline, with final disciplinary authority vested in the Board of Regents. New York Education Law §6530(11) makes it professional misconduct for a physician to permit, aid, or abet an unlicensed person to perform activities requiring a license, and parallel provisions apply to other licensed professionals.

How enforcement actually unfolds

The New York State Education Department has reported more than 2,700 illegal practice cases opened since 1997 and more than 800 compliance agreements secured administratively, with serious matters referred to the state Attorney General for criminal prosecution. Documented examples include an unlicensed individual conducting physical examinations in an apartment and unlicensed individuals practicing dentistry. The dual-track structure matters for functional practitioners because a case against a coach, nutritionist, or nurse will typically move through the Office of the Professions rather than through the Department of Health's physician discipline arm.

Representative case: licensed clinical social worker delegating treatment

In a Regents action dated March 10, 2026, a New York Licensed Clinical Social Worker did not contest the charge of delegating the treatment of a client to an unlicensed employee who held only a baccalaureate degree in psychology. The Board of Regents granted a consent order imposing a one-month actual suspension, a twenty-three-month stayed suspension, two years of probation, and a $5,000 fine. The case is a useful benchmark for the integrative and mental health space: the misconduct was not that the social worker committed a discrete act of malpractice, but that she allowed an unlicensed person to carry out clinical care that her license authorized only her to perform. The structural pattern is identical to the one that gets functional medicine clinics in trouble when an RN, health coach, or wellness consultant is functionally doing the clinical work under a supervising clinician's name.

New York also illustrates a pattern worth noting for practitioners who move across state lines. Under Education Law §6530, discipline imposed by another state's board is independently actionable in New York, meaning that a Texas Medical Board action or a Florida Department of Health cease-and-desist order against a New York–licensed professional can trigger a second proceeding in New York regardless of where the underlying conduct occurred.

Cross-Cutting Patterns Across the Four States

Several patterns emerge when the enforcement activity in Texas, California, New York, and Florida is viewed together. First, pure health and functional coaches without any clinical license face real but episodic exposure, usually triggered by a competitor complaint (as in Del Castillo) or by patient harm. When they are pursued, the enforcement tool is typically a cease-and-desist order and civil or criminal penalties through the state attorney general or a consumer-protection arm, rather than a medical board accusation.

Second, registered nurses are most frequently pursued not by the medical board but by their own board of nursing, and almost always in the context of IV clinics, hormone and pellet programs, peptide clinics, and medical spas where the RN has drifted into independent diagnosis, treatment planning, or prescribing under a thin layer of physician oversight. When a patient is harmed, both boards may act in parallel, and the physician whose name provided legal cover is typically disciplined for aiding and abetting or for failure to supervise.

Third, social workers and mental health counselors face a distinctive exposure when they incorporate functional medicine concepts into practice. They can legitimately address lifestyle, stress, trauma, and behavioral change, but interpreting labs, recommending supplements for diagnosed conditions, or delegating clinical work to unlicensed staff moves them into territory their licenses do not authorize. The New York LCSW consent order illustrates how even a non-medical licensed professional can be disciplined for a structural delegation problem.

Fourth, and perhaps most importantly for physicians who collaborate with non-physician functional practitioners, the enforcement action that reaches the non-physician almost always reaches the supervising or collaborating physician as well. The aiding-and-abetting and corporate practice of medicine doctrines are not theoretical; they are the primary vehicles by which state medical boards discipline licensees who lend their credentials to business arrangements that would otherwise be illegal.

Practical Takeaways for Integrative and Functional Clinicians

The safest posture for a non-physician functional practitioner is to practice squarely within the scope of the license actually held. For an RN without advanced practice authority, that means education, coaching, and supporting a licensed provider's treatment plan, rather than ordering functional labs, interpreting them independently, or recommending supplements as treatment for diagnosed disease. For a licensed clinical social worker, it means keeping the work in the behavioral, psychosocial, and lifestyle domain and avoiding lab interpretation and supplement prescribing. For a health coach without any clinical license, it means staying in general wellness education, avoiding individualized dietary or supplement advice for clients with diagnosed medical conditions, and being scrupulous about title and marketing language.

Physicians who supervise or collaborate with functional coaches, RNs, or social workers should assume that any patient injury, any competitor complaint, and any marketing overreach will bring the physician into the enforcement proceeding alongside the non-physician. Contracts, standing orders, and delegation agreements should be drafted and reviewed by a healthcare attorney licensed in the relevant state, not copied from online templates. Telemedicine arrangements that cross state lines add another layer of exposure because enforcement can be initiated in either the practitioner's state, the patient's state, or both.

Finally, the language a practice uses in its marketing matters more than most clinicians realize. Calling a service functional health rather than functional medicine, framing recommendations as general educational information rather than individualized treatment, and being transparent about exactly which license a given team member holds are small adjustments that meaningfully reduce enforcement risk without changing the clinical work. State boards generally do not hunt for technical violations; they respond to harm, complaints, and conduct that crosses a clearly recognizable line.

Closing Note

The integrative and functional medicine community has legitimate clinical value to offer patients who have been underserved by conventional care. Protecting that value requires protecting the regulatory framework that distinguishes trained, licensed, accountable clinicians from well-intentioned but unlicensed actors. The cases summarized here are not a deterrent against good integrative practice; they are a map of where the line sits in four of the largest markets in the country, so that clinicians and coaches can build sustainable practices that serve patients well without losing the licenses that make the work possible.
