Idaho Practice Structure Guide: The Professional Entity Statute, the Board's 2016 Disavowal and the Cosmetic Treatment Rule

Entity and Ownership

Idaho Code section 30-21-901 governs professional entities, listing medicine among the professions. Services are rendered only through licensed or authorized managers, members, employees and agents, no interest may be offered to or accepted by anyone other than an individual licensed to render the same specific professional service or a professional entity of such individuals, voting trusts and agreements vesting voting power in another are barred, and transfers are limited to eligible persons. The old professional service corporation chapter in Title 30 is repealed, so older summaries citing it are outdated. We found no Board registration requirement for a medical professional entity and did not verify name designators. A 2017 law-firm article argued that since the Board dropped the doctrine a practice need not be a professional entity at all, which we treat as background and do not follow. A physician assistant statute reportedly lets a physician assistant or group own a practice if supervision requirements are met, and we did not read it.

The Corporate Practice Position

In March 2016 the Board of Medicine reportedly formally disavowed and rejected the corporate practice doctrine and said it would not discipline physicians or physician assistants solely for practicing with or for unlicensed entities. We read that through a law-firm article quoting the Board's notes and found no Board minutes online. Worlton v. Davis (Idaho 1952) is the historic authority and has not been expressly overruled, and a 2020 Idaho State Bar article argues it has little force today. We have not read the opinion. Idaho has no statute codifying the doctrine. The limits that remain are that only licensed people may practice medicine, that knowingly aiding or abetting an unauthorized person to practice is a discipline ground, and that Board rules make it a ground to employ, supervise, direct, aid or abet an unlicensed person performing licensed services or to let another person or organization use one's license. The rule is non-enforcement and not repeal, so a structure still needs licensed clinical control.

The Management Agreement and Fees

Idaho Code section 54-1814 makes it a ground for discipline to divide fees or gifts for professional services with any person, institution or corporation in exchange for referral, and to give or receive rebates. That is referral-linked, a pure percentage fee for management services is not squarely within the text, and we found no Idaho opinion or Board statement on percentage MSO fees. Other grounds cover unethical advertising, failing to safeguard records, failing to supervise assistants and delegating to unqualified people. Board rule 24.33.01.200.04 provides that a supervising physician's duties of medical personnel may not be transferred to a business entity, professional corporation or partnership or assigned to another physician or person, which bars handing supervision to an MSO.

Idaho's key-employee non-compete statute presumes a covenant of 18 months or less reasonable, and courts weigh patient choice and continuity of care for physicians. We found no 2025 or 2026 amendment and no physician-specific ban. We found no transaction notice law for physician practices or MSOs.

The Cosmetic Treatment Rule

The Board of Medicine's rule, with text dated July 1, 2025, defines a cosmetic treatment as an aesthetic treatment prescribed by a physician using devices or products that penetrate or alter tissue, including intense pulsed light, lasers, fillers, muscle immobilizers and sclerosing agents, and includes administering parenteral admixtures and cosmetic treatments in the practice of medicine. Cosmetic treatments may be performed only by a physician or by licensed or unlicensed medical personnel under physician supervision using only non-incisive, non-ablative devices and products. The supervising physician accepts full responsibility, must be trained, must document an evaluation, assessment and plan before the first treatment and must be on site or immediately available. No more than three medical personnel may be supervised at once, six with Board authorization, and the rule requires training verification, patient disclosure that personnel are not physicians and a supervising physician registration form at each location. The Division of Occupational and Professional Licenses issued a 2023 guidance on injectable treatments including Botox and IV hydration and serving as medical director, which treats a standing order or collaborative agreement as something to consider and not a safe harbor. We found no Idaho IV-specific rule, and a 2026 physician assistant bill apparently did not pass.

How We Structure It

As a rule we set up a professional corporation owned by the licensed physician, with no exceptions for what looks like a more flexible state. Patients pay the physician-owned practice. The practice pays the management company a fixed monthly fee under a written management services agreement. The management company pays MedGrid a fixed monthly retainer for consulting. The MSO never practices medicine, and the physician makes every clinical decision. Even though Idaho's Board has disavowed the doctrine, we keep the same physician-owned structure, and the supervising physician's duties stay with a named physician and never move to the MSO.
