CPOM: who may own a medical practice in your state

CPOM is a state-by-state rule, not a federal one

Corporate-practice-of-medicine doctrine restricts who may own equity in, and exercise control over, a practice that delivers licensed clinical care — historically built around physician practices, and extended in many states to other licensed professions through similar professional-entity ownership statutes. There is no federal CPOM law; every version of this rule is a state law or a state licensing board policy, which is exactly why which entities a licensee may use, and who may own them, is controlled by state board and statute rather than a single national standard 1Ref 1U.S. Small Business Administration (2026).Choose a business structure.That PLLC/PC entity variants are creatures of state statute and that the state board and statute control which entities licensees may use — the basis for CPOM-style ownership restrictions being state-set rather than federal..

Some states enforce CPOM-style restrictions strictly, limiting ownership of a PLLC or PC to licensees of the relevant profession. Others are considerably more permissive, tolerating management or investment structures a strict-CPOM state would bar. Confirming which category your state falls into, before you structure ownership, is the whole point of this page.

What the doctrine is actually trying to prevent

The policy concern behind CPOM is straightforward: a lay or corporate owner with no clinical license has a financial interest in the practice's decisions but no professional accountability for the care it delivers, and legislators in many states decided that combination creates pressure to prioritize profit over clinical judgment. Keeping ownership and clinical control with licensees is meant to keep that pressure out of the treatment room.

The doctrine does not generally prevent a licensed practice from hiring staff, contracting with vendors, or using outside administrative help — it targets ownership and control of clinical decision-making specifically, not every business relationship a practice has.

A useful working test, though not a substitute for a state-specific answer, is who makes the final call on a clinical question. Vendors, landlords, and software companies get paid regardless of what happens in the treatment room; an owner does not, which is exactly the alignment CPOM-style rules are designed to police.

Why this shapes your entity choice from the start

Because PLLC and PC entity types are themselves creatures of state statute 1Ref 1U.S. Small Business Administration (2026).Choose a business structure.That PLLC/PC entity variants are creatures of state statute and that the state board and statute control which entities licensees may use — the basis for CPOM-style ownership restrictions being state-set rather than federal., most states that restrict clinical-practice ownership do it by restricting who may hold membership or shares in those specific entity forms — a generic LLC or standard corporation is often not an available option for a licensed solo practice precisely because it lacks that ownership restriction built in. Forming the entity type your state designates for licensed professionals is usually the simplest way to stay inside the CPOM line by default.

Spousal ownership is one of the most common ways solo clinicians run into this rule by accident: adding a spouse who does not hold the license as a co-owner of the PLLC is exactly the kind of non-licensee equity interest CPOM-style rules are built to prevent, even when the intent is purely financial rather than clinical.

Management services arrangements: the workaround, and its limits

Many states that restrict clinical ownership still permit a separately owned management services organization (MSO) to handle the practice's administrative functions — billing, marketing, human resources, facilities — under a contract with the licensee-owned entity, as long as the MSO does not control clinical decisions, treatment protocols, or the licensee's professional judgment. Where administrative support ends and prohibited clinical control begins is drawn differently state to state, and it is enforced with varying rigor.

A management contract that gives the MSO authority over which patients are seen, how they are treated, or hiring and firing of clinical staff looks far more like ownership than administration in a strict-CPOM state, even if the contract itself never uses the word "ownership."

Fee structure is one of the details that gets scrutiny in an MSO relationship: a flat fee or a fee tied to actual administrative costs reads as compensation for services rendered, while a fee that rises and falls with the practice's clinical revenue starts to look like the MSO has an ownership-like stake in outcomes it is not licensed to control. This is exactly the kind of structuring detail worth having a healthcare attorney review before signing, rather than after.

Finding your state's actual rule

Your licensing board is the first stop for confirming which entity types licensees in your state may use, even though CPOM enforcement itself is often a matter of state corporate and health law rather than something the board directly polices. Boards such as Maryland's 2Ref 2Maryland Board of Professional Counselors and Therapists (2026).Maryland Board of Professional Counselors and Therapists.That Maryland's board publishes its own licensure and practice-entity requirements, used as one example of a state-specific authority to check., Oklahoma's 3Ref 3Oklahoma State Board of Behavioral Health Licensure (2026).Oklahoma State Board of Behavioral Health Licensure.That Oklahoma's board publishes its own licensure and practice-entity requirements, used as one example of a state-specific authority to check., and Kentucky's 4Ref 4Kentucky Board of Licensed Professional Counselors (2026).Kentucky Board of Licensed Professional Counselors.That Kentucky's board publishes its own licensure and practice-entity requirements, used as one example of a state-specific authority to check. each publish their own licensure and practice-entity requirements directly on their sites — a state-by-state check, not a single lookup that covers all three.

A question this specific and this consequential — whether a proposed ownership or management structure crosses into prohibited territory in your state — is a genuine trigger for a healthcare attorney licensed in that state, not a question your board's front desk or a general business-formation service is positioned to answer.

What this means when structuring your practice

Treat any proposed ownership or investment arrangement involving a non-licensee — a spouse, a business partner, an outside investor — as a CPOM question before it is a tax or logistics question, and confirm it against your state's rule before signing anything. The same caution applies to management contracts that give an outside company influence over clinical staffing or treatment decisions rather than pure administration.

Getting the entity's ownership structure right also matters for downstream mechanics like registering the second npi the entity needs once it employs or contracts with more than the sole owner — an entity whose ownership is later found to be improperly structured can complicate enrollment and credentialing built on top of it, not just the initial formation.

Naming the practice is a smaller, related decision worth making at the same time: a name that implies corporate or investor ownership, rather than a named licensee's practice, can itself draw the kind of scrutiny a cleanly structured entity would otherwise avoid, on top of whatever rules govern naming a practice under your state's licensing statute directly.
