What is the corporate practice of medicine?
The corporate practice of medicine (CPOM) doctrine is a legal principle in many US states that bars corporations not owned by licensed physicians from practicing medicine, employing physicians or controlling medical decisions. Some states enforce it strictly, others loosely or not at all, and exceptions exist for hospitals and certain entities. It shapes who can own med spas and clinics and how management companies work.
- Purpose: keep clinical judgment with licensed professionals, not lay investors.
- Strictness varies widely by state; some have similar rules for dentistry.
- Common workaround: a physician-owned practice plus a management services organization (MSO).
- Marketing angle: who approves clinical claims, and how marketing fees are structured.

“They were able to get all my ideas and work with me over a period of three to four months and create this amazing website. It's super customized, very modern, and it incorporates all the elements that I had wanted — the patient portal, nice pictures, a very interactive website, patient reviews. I would highly recommend their company to anyone who wants to make an excellent website.”
What the doctrine is
CPOM comes from state medical practice acts, court decisions and attorney general opinions. The core idea is that only licensed professionals, or entities they own, may practice medicine. In states that follow it, a business corporation owned by non-physicians generally cannot employ doctors to provide care or direct how they treat patients.
States apply this differently. Some, often cited as including California, Texas and New York, are considered strict. Others allow more corporate employment or have broad exceptions for hospitals, health maintenance organizations or specific facility types. Many states apply a parallel rule to dentistry, and some to other professions. Rules can change through new legislation.
The common business structure in strict states is a professional entity owned by licensed clinicians, which contracts with an MSO owned by investors or lay owners. The MSO provides non-clinical services such as billing, staffing, real estate and marketing for a fee, while clinical control stays with the professional entity.
How it applies to practice marketing
- Med spa ownership: many states limit who can own a business offering injectables and lasers; see med spa ownership rules by state.
- Clinical content approval: marketing claims about treatments should be approved by the licensed clinicians, not set only by an MSO or investor.
- Fee structures: in some states, marketing or management fees calculated as a percentage of professional revenue can raise fee-splitting concerns. Structures need legal review.
- Branding: the public brand should not mislead patients about who provides care.

Common mistakes and limits
A common mistake is assuming one state's model works everywhere. A structure that is fine in one state can be a problem in a neighboring one. Another is an MSO that controls scheduling rules, protocols or treatment pricing in ways that look like clinical control.
CPOM also interacts with fee-splitting bans, anti-kickback rules and state self-referral laws, which affect how marketing vendors are paid. This entry is a high-level summary, not legal advice. Practices and investors should get advice from a healthcare attorney in each state where they operate. For marketing teams, the practical step is to document who approves what: the MSO can run campaigns, budgets and vendors, while licensed clinicians sign off on treatment descriptions, outcome claims and anything that reads as medical advice.

Common questions
Which states have corporate practice of medicine rules?
Many states have some form of CPOM doctrine, through statutes, court decisions or attorney general opinions. States often described as strict include California, Texas and New York, while others are looser or have broad exceptions. The rules change, so check current law in each state with a healthcare attorney.
Can a non-doctor own a med spa?
It depends on the state. In states with strict corporate practice of medicine rules, a non-physician often cannot own the medical part of the business directly and may use a physician-owned entity with a management services organization. Other states allow broader ownership. Get state-specific legal advice.
What is an MSO in the corporate practice of medicine context?
A management services organization is a company that provides non-clinical services, such as billing, staffing, facilities and marketing, to a physician-owned practice under a contract. It lets lay investors participate in strict CPOM states while clinical control stays with licensed professionals.
Does corporate practice of medicine affect marketing agreements?
It can. In some states, paying a marketing or management company a percentage of professional fees can raise fee-splitting concerns, and clinical claims should be approved by licensed clinicians. Practices should have marketing and MSO agreements reviewed by a healthcare attorney.
