ANSWER

What is the corporate practice of medicine?

Updated 2026-08-25 · MedSpaForms

The short answer

The corporate practice of medicine doctrine is a state-level rule prohibiting corporations and non-physicians from practicing medicine, owning a medical practice, employing physicians, or controlling clinical decisions. It exists to keep business judgment from overriding medical judgment. Enforcement varies sharply: Texas, New York and California apply it strictly, while Florida and Arizona impose few restrictions. Med spas are a primary enforcement target.

Where does the doctrine come from and what does it forbid?

The corporate practice of medicine doctrine developed from state medical practice acts, medical board rules and state court decisions, mostly in the first half of the twentieth century. Its premise is that a license to practice medicine is granted to an individual, so a corporation cannot hold one, and a corporation that employs physicians would inevitably subordinate clinical judgment to profit. There is no single federal CPOM statute — this is fifty separate bodies of law.

In strict states, the doctrine typically bars four things: a lay person or lay corporation owning an entity that provides medical services; a lay entity employing physicians to deliver medical care; a non-physician controlling clinical decisions such as protocols, treatment selection, staffing of clinical roles or patient volume targets; and fee-splitting, meaning sharing professional fees with a non-licensee, which is often policed under separate anti-kickback and fee-splitting statutes.

The doctrine cuts across three areas most med spa owners think about separately: who can own, who can employ, and who can decide. A structure can be legal on ownership and still fail on control.

Which states enforce it hardest?

StateEnforcement posturePractical effect on a med spa
TexasVery strictClinical entity must be physician-owned; MSO model is standard
New YorkStrictPractice of medicine reserved to physician-owned PC or PLLC
CaliforniaStrictMedical Board actively addresses lay-owned med spas; MSO required
IllinoisStrict, with statutory carve-outsProfessional corporation requirements govern ownership
ColoradoModerateFewer restrictions; advanced practice ownership common
FloridaPermissiveNo general CPOM bar for most arrangements
ArizonaPermissiveLay ownership of many aesthetic businesses is workable

Even permissive states regulate delegation and supervision. Florida not owning a CPOM doctrine does not mean an unlicensed owner may inject. Ownership rules and scope-of-practice rules are separate gates, and you have to clear both.

How does the MSO model work, and how does it fail?

The management services organization model splits the business in two. A physician-owned professional entity employs the clinicians, owns the medical records, controls protocols and clinical decisions, and receives the professional fees. A separately owned MSO holds the lease, equipment, brand, non-clinical staff, marketing and administrative systems, and provides those services to the professional entity under a written management agreement.

Regulators attack the model on three fronts. Compensation: a management fee set as a percentage of clinical collections looks like fee-splitting in states that prohibit it, and fair market value flat or cost-plus fees are the safer structure. Control: if the MSO hires and fires clinicians, sets protocols, dictates treatment volumes or controls the charts, the professional entity is a shell. Substance: if the physician owner never reviews a chart, never visits, and cannot name the protocols, boards treat the arrangement as a straw ownership.

What this means for your paperwork

If you operate in a CPOM state, your file should contain the professional entity formation documents showing physician ownership, the MSO formation documents, a written management services agreement with a documented fair market value basis for the fee, an employment or independent contractor agreement between the professional entity and each clinician, and a medical director agreement with defined duties.

Then prove the substance. Keep dated chart review logs signed by the physician, signed and dated protocols and standing orders with a revision history, meeting notes showing the physician set or approved clinical policy, and evidence of separate bank accounts, separate payroll and separate contracts. The documents that save an MSO structure in an investigation are the ones showing the physician actually exercised clinical control — not the agreement that says they were supposed to.
