Key Takeaway:
No. Under California’s CPOM doctrine and related corporation laws, majority ownership and clinical control must remain with licensed physicians. Unlicensed individuals cannot own a medical practice, but may participate through properly structured non-clinical arrangements such as an MSO.
Many investors and entrepreneurs ask whether they can invest in or become shareholders of a California business that provides medical services. This is a critical question to answer before putting money into any healthcare venture.
So, can a non-physician own a medical practice?
California law is strict: “silent partner” and minority ownership assumptions often lead to non-compliant structures.
Let’s break down what the rules say and how non-licensed individuals can legally get involved in the business.
Can a Non-Physician Own a Medical Practice in California? (CPOM Rule Explained)
Laws regulating medical practice ownership primarily provide guidance for California’s corporate practice of medicine (CPOM) rules. As explicitly stated in California Business and Professions Code § 2400: “Corporations and other artificial legal entities shall have no professional rights, privileges, or powers.”
The question of, “Can a non-physician own a medical practice?” is clearly answered by the California corporate practice of medicine rules. In practical terms, CPOM means non-licensed owners cannot control medical decision-making or physician practice operations tied to patient care.
The CPOM doctrine also does more than just define who may be an owner or shareholder. California medical practice ownership laws aim to prevent unlicensed individuals and corporate/investor interests from interfering.
That means, in practice, CPOM goes beyond simple ownership restrictions, as it governs who controls clinical judgement – from hiring physicians and other medical staff to how patient care is provided.
Any arrangement that would allow non-physicians to interfere or influence these areas – and decisions that affect them – could violate California CPOM laws.
What Decisions Must Be Made Only by Licensed Physicians
Under California’s CPOM rules, according to the Medical Board of California, core patient-care decisions constitute the practice of medicine. And these cannot be done by unlicensed individuals or entities.
CPOM violations usually arise when a non-physician owner has the power to influence clinical judgment, physician compensation tied to patient care, or medical decision-making authority.
Clinical Decisions That Directly Affect Patient Care
Only individuals with active California physician license may determine:
- What diagnostic tests are appropriate for a patient’s condition
- Whether referrals or specialist consultations are necessary
- The treatment options available to the patient
- The overall responsibility for a patient’s care
- How many patients a physician must see or how many hours they must work
If a non-physician controls or dictates these decisions, it may constitute the unlicensed practice of medicine.
Decisions on Medical Practice Operations
There are also certain “business” or “management” decisions can amount to control over medical practice, so they must remain with licensed physicians. These include:
- Control over access to, use of, and clinical decision-making related to patient medical records
- Hiring or firing physicians and clinical staff based on competency
- Establishing contractual relationships with third-party payers
- Coding and billing procedures for patient care services
- Selection and approval of medical equipment and medical supplies
Even though these decisions may appear administrative, when they affect patient care or clinical judgment, they are governed by California corporate practice of medicine rules.
What Entity Can Operate a Medical Practice in California?
BPC § 2402 clarifies that a Medical Corporation — a type of professional corporation — may operate a medical practice. This business entity is governed by the Moscone-Knox Professional Corporation Act. It is subject to strict compliance and specific requirements, including medical PC ownership rules in California.
For example, Corporations Code § 13401 defines professional corporations as businesses that provide professional services through duly licensed individuals for the same profession.
In this case, a Medical Corporation can provide clinical services through licensed physicians and other licensed healthcare professionals it employs.
And this is where California rules on corporate practice of medicine and professional corporation go hand in hand.
For medical practices, this means:
- The entity must be a Professional Medical Corporation
- Clinical services are provided by licensed physicians
- Ownership and control remain with physicians
That’s also why, apart from non-physicians and unlicensed individuals, general business corporations, LLCs, and holding companies cannot own or operate medical practices.

Who Can Own a Medical Corporation in California?
Only licensed physicians and surgeons for a medical corporation, and licensed podiatrists for a podiatry corporation, may own 51% or more of the total shares of a California professional medical corporation.
Who Can Own Up to 49% of a Medical Corporation in California?
Certain licensed allied healthcare professionals, who are not necessarily physicians and surgeons, may hold a minority ownership. This means only owning up to 49% of the total shares of a medical or podiatry corporation, according to CORP § 13401.5.
These individuals are not “outside investors.” They must hold an active license in a profession listed in the statute.
For a Medical Corporation:
- Licensed doctors of podiatric medicine
- Licensed psychologists
- Registered nurses
- Licensed optometrists
- Licensed marriage and family therapists
- Licensed clinical social workers
- Licensed physician assistants
- Licensed chiropractors
- Licensed acupuncturists
- Naturopathic doctors
- Licensed professional clinical counselors
- Licensed physical therapists
- Licensed pharmacists
- Licensed midwives
- Licensed occupational therapists
For a Podiatric Medical Corporation:
- Licensed physicians and surgeons
- Licensed psychologists
- Registered nurses
- Licensed optometrists
- Licensed chiropractors
- Licensed acupuncturists
- Naturopathic doctors
- Licensed physical therapists
Remember that this allowance still does not apply to businesspersons or investors.
Quick Recap:
Who can be involved in owning a medical corporation in California?
- Allowed: Licensed physicians owning and controlling the Medical Corporation.
- Sometimes allowed: Certain licensed healthcare professionals holding minority shares (up to 49%) where permitted by statute.
- NOT allowed: Unlicensed individuals or investment companies owning shares in a Medical Corporation.
Can Non-Professionals Be Involved in a Medical Practice at All?
Yes, but not through ownership. California law does allow non-professionals to participate in the business side of medical practice if the structure is properly designed to avoid CPOM violations.
Physicians may consult with or contract non-professional entities — such as Management Services Organizations (MSOs) — for administrative support. — for administrative support. — for administrative support.
Investors without a professional license may take part through an MSO that’s under a separate business entity, providing non-clinical services to physician-owned medical practices.
This is where non-physicians and unlicensed individuals can get legally involved in a medical practice, provided that:
- Licensed physician still owns the medical practice
- The MSO does not provide or get involved in decisions related to medical care
- The MSO is paid at fair market value for its services
This model is widely used in California to allow lawful business involvement without violating CPOM.
What Can You Legally Do Through an MSO (and What You Cannot Do)
Through an MSO, non-licensed individuals may handle:
- Administrative operations and office management
- Billing and collections (e.g. insurance claims, payment processing)
- Human resources for non-clinical staff
- Non-medical facilities and equipment management
What an MSO cannot do in California:
- Make treatment or diagnosis decisions
- Control physician hiring/firing based on clinical competency
- Direct physician schedules in a way that affects clinical judgment
- Own patient medical records or restrict clinical access
- Receive compensation tied directly to medical fees (percentage-of-revenue models may create risk)
Overall, it doesn’t change the fact that ownership and control of medical practice are strictly off-limits for non-physicians. Non-licensed individuals, even through MSOs, still cannot be directly involved or influence clinical care, treatment decisions, or physician judgment.
Common Mistakes Non-Physicians Make When Investing in Medical Practices
In most cases, mistakes that ultimately violate CPOM rules happen unintentionally. That’s because investors or business owners often misunderstand how strictly the state regulates medical practice ownership and control.
Common errors include:
- Investing without healthcare-specific legal review: This could lead to entity structures, operating agreements, or ownership arrangements that appear valid on paper but are non-compliant for medical practices, particularly when professional corporation rules are ignored.
- Blending MSO and medical corporation finances: MSO must be a separate entity from a medical corporation. And improper commingling of funds between these formations is an obvious red flag.
- Entering management agreements with excessive control: Non-physician individuals and entities must not be involved in aspects that may seem “administrative” on the surface. These include physician schedules, staffing decisions tied to clinical competency, and medical equipment procurement.
These missteps can undermine the legality of the entire ownership structure and expose you to regulatory scrutiny. CPOM violations can expose the arrangement to enforcement risk, contract challenges, fee disputes, and potential licensing consequences for physicians involved.

FAQs: Can a Non-Physician Own a Medical Practice?
Can a corporation own a medical practice in California?
Only a Professional Medical Corporation or Professional Podiatry Corporation may operate a medical practice in California. General business corporations, holding companies, and unlicensed entities cannot own or control medical practices due to CPOM restrictions.
Can a non-physician own a medical practice or be a shareholder in a medical corporation in California?
Unlicensed individuals cannot own shares under medical corporation shareholder rules in California. However, certain licensed healthcare professionals who are not physicians may hold minority shares (up to 49%) if specifically permitted under California Corporations Code § 13401.5.
Can a medical practice be an LLC in California?
Generally, no. Medical practices in California are typically formed as professional corporations, not LLCs, under the Moscone-Knox Professional Corporation Act. This structure ensures licensed professionals retain legal responsibility and clinical control over medical services.
Can individuals without professional license get involved in California medical corporations?
Yes, but not through ownership. Non-licensed individuals may participate through a separate Management Services Organization (MSO) that provides non-clinical support services. But MSO agreements in medical practice must clearly state that the MSO cannot control clinical decisions or interfere with physician judgment.
How Non-Physicians Can Legally Participate in California Medical Practices
Can a non-physician own a medical practice? No, and California law leaves little ambiguity on this point. Only licensed physicians can be owners and primary decision-makers.
However, with proper legal structuring, non-physicians can still participate in the business side of healthcare without violating the law.
