What is the corporate practice of medicine doctrine in California?

California is the strictest CPOM state in the country. The doctrine traces back to People v. Pacific Health Corp., 12 Cal.2d 156 (1938), where the California Supreme Court held that a general business corporation cannot lawfully practice medicine through licensed physician employees. The statutory anchor is Business and Professions Code §2400. Section 2052 reinforces the rule by criminalizing unlicensed practice. Together these two sections mean a general C-corp, LLC, partnership, or non-physician individual cannot own, employ, or financially control physicians for the purpose of delivering patient care. The only entity that may employ physicians for clinical work is a Professional Corporation formed and operated under the Moscone-Knox Act.

Which California statutes govern CPOM compliance?

Six provisions do most of the work. Business and Professions Code §2400 bars corporate practice. Business and Professions Code §2052 prohibits unlicensed practice. Business and Professions Code §2056 protects physicians from retaliation for advocating medically appropriate care. Business and Professions Code §2408 requires that all shareholders, directors, and officers of a medical or podiatry PC be licensed (asst. secretary and asst. treasurer are the narrow exceptions). Corporations Code §13401.5 sets the 51-percent physician ownership rule and lists the limited categories of allied health professionals who can hold the minority interest. Corporations Code §17701.04 prohibits LLCs from providing professional services unless a licensing act authorizes it, and the Medical Practice Act does not.

Who can legally own a medical practice in California?

Only California-licensed physicians can hold a majority of a medical Professional Corporation. Under Corporations Code §13401.5, up to 49 percent of the shares of a medical PC may be held by a closed list of allied licensees, including registered nurses, nurse practitioners, physician assistants, psychologists, chiropractors, optometrists, podiatrists, and a few others. The count of allied owners cannot exceed the count of physician owners. Owners must hold active, unrestricted licenses (BPC §2415). Inactive, suspended, or revoked licensees cannot remain shareholders. Non-licensed individuals, investors, and private equity funds cannot own equity in the clinical PC. They can only participate through a separate Management Services Organization that limits itself to non-clinical work.

What are the 12 CPOM compliance requirements for California medical practices?

Use this list as a recurring compliance audit. Every box should be checked, in writing, with documentation in the corporate book.

1. Form the clinical entity as a Professional Corporation under Moscone-Knox, not an LLC, LLP, or general business corporation. LLCs cannot provide medical services in California (Corp. Code §17701.04).
2. Confirm that at least 51 percent of the PC's shares are held by California-licensed physicians and surgeons, with any minority allied ownership matching the categories listed in Corp. Code §13401.5 and capped at 49 percent.
3. Verify that every shareholder, director, and officer (other than assistant secretary or assistant treasurer) holds an active, unrestricted California license, per BPC §2408 and §2415.
4. Adopt the PC name correctly. The corporation must include 'Medical' or the licensee's surname plus 'M.D., A Professional Corporation,' or operate under a Medical Board-issued fictitious name permit under BPC §2415.
5. Draft bylaws that vest clinical authority (diagnosis, treatment, prescribing, hiring or firing of clinical staff, medical record content) exclusively in physician-owners. The Medical Board lists these as non-delegable decisions.
6. Confirm the PC, not the MSO, owns and controls the patient medical records. Record custody is a primary CPOM indicator under Medical Board guidance.
7. If using an MSO, the Management Services Agreement must limit the MSO to non-clinical services: billing, payroll, IT, marketing, real estate, and staffing of non-clinical personnel. No clinical decision rights.
8. Set the MSO management fee at fair market value, supported by a valuation memo. Percentage-of-revenue fees raise fee-splitting concerns under BPC §650 and require careful structuring.
9. Carry medical professional liability insurance on the PC, plus general liability and cyber. General liability alone is not adequate for a medical practice.
10. Display the PC name and at least one supervising physician's name on all advertising, signage, websites, and patient consents. Required under BPC §651 and §2272.
11. Establish written standardized procedures for every nurse-delegated treatment, satisfying 16 CCR §1474. For laser and IPL procedures, a supervising physician must be immediately available, per 16 CCR §1364.50.
12. Conduct a written CPOM compliance audit at least once per calendar year. Document the review, fix any gaps, and refresh the MSA, bylaws, and standardized procedures to reflect current Medical Board guidance and recent enactments.

What are the penalties for CPOM violations in California?

Penalties are layered. Business and Professions Code §2417.5 specifically targets businesses offering outpatient elective cosmetic medical procedures: non-compliance counts as a knowingly false or fraudulent claim under Penal Code §550. Section 550 felony penalties include fines up to $50,000 per occurrence (or twice the value of the fraud) and imprisonment of two, three, or five years. The Medical Board can also revoke or suspend any licensee who aids unlicensed practice under BPC §2264. The Envision Healthcare CPOM litigation (filed in 2021) ended with Envision exiting the California market in 2024 even without a final ruling. Recent legislation effective January 1, 2026 has intensified enforcement. The practical risk is not theoretical.

How does the PC-MSO structure help California practices comply with CPOM?

The compliant structure splits clinical and business operations into two separate entities. The clinical PC, owned by licensed physicians, employs the providers and owns the medical records. The MSO, which can be owned by non-physician investors, owns the equipment, leases the real estate, hires non-clinical staff, runs billing and IT, and contracts with the PC for those services through a Management Services Agreement. The MSO charges the PC a management fee at fair market value. Done correctly, the PC owners can sell the MSO equity to outside investors without violating CPOM, because the investors never touch clinical decisions. Done incorrectly, where the MSO controls firing of physicians, sets clinical protocols, or takes a percentage of clinical revenue without FMV support, the structure collapses into a CPOM violation.

What are the limited exceptions to CPOM in California?

There are four narrow exceptions. Licensed charitable institutions, foundations, and clinics may employ physicians on a salary basis if no patient charges are made for the professional services (BPC §2400 itself contains this carve-out). Certain medical foundations may employ physicians under BPC §2401. Public hospitals and government-operated facilities have statutory authority to employ physicians. Hospital districts and county-operated clinics also fall within recognized exceptions. None of these apply to private medical groups, medical spas, telehealth startups, or private-equity-backed practices. Telehealth companies in particular have been a recent Medical Board enforcement focus. The general rule is that if money flows from patients to a private business and physicians are employees of that business, the structure needs CPOM analysis.

Compliant vs non-compliant structures at a glance

How often should a California medical practice audit its CPOM compliance?

Annually at minimum, and within 60 days of any material change. Material changes include adding or removing a shareholder, executing or amending an MSA, hiring or terminating a medical director, opening a new location, beginning a new service line (especially anything cosmetic, weight loss, hormone therapy, or telehealth), or any inquiry from the Medical Board or DCA. The audit should be a written exercise, signed by counsel, kept in the corporate book. The standardized procedures, bylaws, and MSA all drift over time as the practice evolves. The annual audit catches the drift before it becomes a violation.

What is a will in California?

A will is a written document that takes effect at death. It names the executor, directs how the testator's property is distributed, names a guardian for minor children, and lists specific gifts to specific people or charities. To be valid in California, the will must be in writing, signed by the testator, and signed by two witnesses who watched the testator sign (Probate Code §6110). Holographic wills, fully in the testator's own handwriting, are valid without witnesses (Probate Code §6111). A will controls only probate assets. It does not control assets held in trust, beneficiary-designation accounts, or joint tenancy property.

What is a revocable living trust in California?

A revocable living trust is a legal entity created during the grantor's lifetime to hold assets. The grantor transfers title of real estate, bank accounts, brokerage accounts, and other property into the trust's name. During life, the grantor typically serves as trustee and beneficiary, retaining full control. The trust document names a successor trustee who takes over at incapacity or death. Because the trust (not the grantor personally) owns the assets at death, those assets pass to beneficiaries under the trust terms without probate. The trust is revocable: the grantor can change beneficiaries, add or remove assets, or dissolve the trust at any time during life.

What is California probate, and why do people try to avoid it?

California probate is the court process that validates a will, supervises the executor, pays creditors, and distributes assets. It takes nine to eighteen months on average. It is public, so the inventory and family disputes become part of the court record. The statutory attorney and executor fees are set by Probate Code §10810 and §10800 and run roughly four percent of the first $100,000, three percent of the next $100,000, two percent of the next $800,000, and one percent of the next $9 million. On a $1 million estate that is approximately $23,000 in statutory attorney fees plus the same amount in executor fees, plus filing fees, plus extraordinary fees. The probate process is the single biggest reason California estate plans use revocable trusts.

What is the California small estate procedure?

California Probate Code §13100 lets heirs collect probate assets without a full probate proceeding if the decedent's California personal probate property is worth less than the small estate limit. The limit was raised to $208,850 for deaths occurring on or after April 1, 2025. The procedure uses a simple sworn affidavit, presented to the bank or institution holding the asset. Real property up to the same threshold can be transferred using a Petition to Determine Succession to Real Property under Probate Code §13150. For estates above the threshold, the small estate shortcut is unavailable, and the family generally faces full probate unless a living trust holds the qualifying assets.

California living trust vs. will: side-by-side comparison

When does a California living trust make sense?

• Estate value above the $208,850 small-estate threshold.
• Real estate ownership in California (the home alone usually pushes the estate above the threshold).
• Real estate in multiple states (a trust avoids ancillary probate in each state).
• Privacy concerns about who inherits what.
• Blended family situations where the grantor wants to direct distribution in a specific way after a surviving spouse's death.
• Minor children or beneficiaries with disabilities, where ongoing trustee management is needed.
• High-net-worth families with potential estate tax exposure (the trust does not eliminate estate tax but is the foundation for tax planning).
• Concerns about incapacity (the successor trustee can manage trust assets without a court-supervised conservatorship).

When does a simple will make sense?

• Estate value comfortably below the $208,850 small-estate threshold.
• No California real estate.
• Limited assets that all transfer by beneficiary designation (retirement accounts, life insurance, transfer-on-death accounts).
• Young adults without significant assets who primarily need a guardian designation for minor children.
• Comfort with the small-estate affidavit procedure.
• Cost sensitivity, with a plan to revisit if assets grow.

Why most California estate plans use both a trust and a pour-over will

The trust holds the major assets and avoids probate for them. The pour-over will catches anything not transferred to the trust during life. It directs that any asset still in the grantor's personal name at death pours over into the trust at death. That single move keeps the estate plan unified and prevents an inadvertently untitled asset (a forgotten brokerage account, a recently purchased car) from creating a probate proceeding that bypasses the trust. The will also names guardians for minor children, which a trust cannot do. The will and the trust are a pair, not alternatives.

What does 'funding the trust' mean, and why does it matter?

A revocable living trust only avoids probate for assets actually titled to the trust. Creating the trust document is step one. Retitling the home, bank accounts, brokerage accounts, and other major assets into the name of the trust is step two. If step two never happens, the trust is empty at death, the assets pass through the grantor's name, and probate happens anyway. Funding the trust requires a recorded deed for California real estate, retitling letters for accounts, and beneficiary changes on certain accounts (with the trust as a beneficiary, not the owner, for retirement accounts). The funding step is where most do-it-yourself trusts fail.

Why does a California medical spa need a specific structure?

California prohibits corporations and non-physician entities from owning a medical practice under Business and Professions Code §2400. Because almost everything a medical spa does (Botox, fillers, laser hair removal, IPL, medical-grade peels, sclerotherapy, IV therapy) qualifies as the practice of medicine under California Medical Board guidance, the spa is a medical practice with a spa label. The structure has to satisfy CPOM. The wrong structure (LLC, lay-owned corporation, RN-only-owned PC, paper-medical-director arrangement) creates Medical Board enforcement exposure, criminal liability under BPC §2417.5 cross-referenced to Penal Code §550, and personal license risk for the supervising physician.

Option 1: physician-owned Professional Corporation only

The simplest compliant structure. One physician (or a small group of physicians) forms a Moscone-Knox Professional Corporation that owns and operates the medical spa. The physician-owner serves as the medical director, hires the clinical staff, owns the medical records, and runs the business side directly. Allied owners (NPs, PAs, RNs) can hold up to 49 percent under Corp. Code §13401.5, with physician majority preserved. The PC handles everything: clinical services, billing, marketing, real estate, equipment. No MSO. No MSA. Lower complexity, lower setup cost, and a tighter compliance posture.

Option 2: PC paired with an MSO under an MSA

The structure used when non-physician capital is involved. The clinical PC is owned at least 51 percent by California-licensed physicians. The MSO is a separate entity (typically an LLC or C-Corp) that can be wholly owned by non-physicians (investors, family offices, private equity). The two entities sign a Management Services Agreement under which the MSO provides administrative services (real estate, equipment, non-clinical staffing, billing, marketing, IT) and the PC pays a management fee at fair market value. The PC retains clinical authority and owns the medical records. The MSO provides the capital and operational infrastructure. The MSA defines the line.

PC-only vs. PC-MSO comparison

How do I decide between PC-only and PC-MSO?

Three filters. First, who is providing the capital? If only physicians (and possibly allied licensees under §13401.5) are funding the spa, PC-only is the simpler choice. If non-physician capital is involved or anticipated, PC-MSO is required. Second, what is the growth plan? A single location with a single physician-owner does fine as a PC. Multi-location growth, geographic expansion, or buy-and-build strategies almost always need PC-MSO so the MSO can scale across multiple PCs. Third, what is the exit plan? Selling a clinical PC requires a licensed buyer and limits the buyer universe. Selling an MSO is a standard M&A transaction. If exit optionality matters, PC-MSO.

What does a compliant PC-MSO setup look like operationally?

• Two separate legal entities, each with its own EIN, bank accounts, payroll, and tax returns.
• The PC employs physicians, NPs, PAs, and RNs delivering care. The MSO employs the front desk, billers, marketers, IT, and non-clinical leadership.
• The MSA is in writing, current, executed, and supported by an annual FMV valuation memo.
• The PC owns the EHR contract and the medical records. The MSO can administer the EHR but does not own it.
• Patient-facing materials (website, intake forms, signage, ads) name the PC and the supervising physician (BPC §651).
• Standardized procedures for nurse-delegated treatments are PC documents, drafted with physician input, satisfying 16 CCR §1474.
• Laser supervision protocols satisfy 16 CCR §1364.50: a physician with relevant training is immediately available during laser or IPL procedures.
• Medical professional liability insurance is on the PC. General liability and cyber are on the MSO.
• Annual CPOM audit is on file. Annual FMV refresh is on file.

What does a non-compliant structure look like (and how to fix it)?

Special situations: telehealth-enabled spas, multi-state operators, and franchise spas

Telehealth med spas need careful good-faith-exam protocols satisfying the California Medical Board's published telehealth guidance, plus standardized procedures that match the platform's clinical workflow. Multi-state operators usually run one MSO that contracts with one PC per state, since each state has its own CPOM rules and ownership requirements. Franchise spas in California cannot franchise the clinical entity (the PC), but they can franchise the MSO's branding, operating systems, and marketing. The franchise agreement and the MSA must be drafted together so the franchise doesn't accidentally exercise clinical control through brand standards.

What are the three entity types?

An LLC (Limited Liability Company) is a flexible entity that gives owners limited liability while allowing pass-through federal taxation by default. An S-Corporation is a federal tax election under IRC §1361 that lets a corporation (or eligible LLC) pass income through to shareholders' personal returns, avoiding C-Corp double taxation. A C-Corporation is the default corporation form: the entity pays its own income tax, and shareholders pay tax again on dividends. All three offer personal liability protection for owners when properly maintained. The differences are in taxation, ownership flexibility, fundraising, and ongoing administration.

California LLC vs. S-Corp vs. C-Corp side-by-side comparison

How much does each entity cost annually in California?

Every California LLC, S-Corp, and C-Corp pays the $800 minimum franchise tax under R&T Code §17941. For LLCs, an additional gross receipts fee kicks in under R&T Code §17942 at four tiers: $900 (gross receipts $250,000 to $500,000), $2,500 ($500,000 to $1,000,000), $6,000 ($1,000,000 to $5,000,000), and $11,790 (above $5,000,000). For S-Corporations, the franchise tax is the greater of $800 or 1.5 percent of California-source net income. For C-Corporations, the franchise tax is the greater of $800 or 8.84 percent of California-source net income. Filing fees with the Secretary of State are modest: $70 for LLC formation, $100 for corporation formation, plus annual Statement of Information fees of $20 to $25.

When should I choose an LLC in California?

• Real estate holding entities (each property in its own LLC).
• Single-member or small partnerships in non-professional services.
• Businesses where members want pass-through taxation without S-Corp shareholder restrictions.
• Businesses where flexibility in profit and loss allocation matters (LLC operating agreements can allocate differently from ownership percentages, subject to IRS substantial economic effect rules).
• Businesses with foreign owners (LLCs allow non-US owners; S-Corps do not).
• Businesses unlikely to seek priced equity rounds (LLC capitalization is awkward for VC investment).

When should I choose an S-Corporation in California?

• Profitable owner-operated businesses where the owner-operator pays themselves a reasonable salary and takes the remainder as distributions (saves on self-employment tax compared to LLC).
• Small businesses with US-individual owners only.
• Service businesses with one class of stock and predictable distribution patterns.
• Professional services that have to use a corporate form anyway (form a Professional Corporation, then elect S-Corp federal taxation).
• Businesses planning to stay closely held without outside investment.

When should I choose a C-Corporation in California?

• Startups planning to raise priced equity rounds (VCs almost universally require Delaware C-Corp structure, with California foreign qualification).
• Businesses that need multiple stock classes (preferred, common, convertible).
• Businesses with non-US owners or institutional investors.
• Businesses planning to issue stock options or grants under §83(b) or §1202 QSBS treatment.
• Businesses planning an eventual IPO or strategic acquisition by a public company.
• Businesses where retained earnings will be reinvested in growth rather than distributed.

Why can't California professional services use an LLC?

California Corporations Code §17701.04 prohibits LLCs from rendering professional services unless the licensing act authorizes it. The Medical Practice Act, the State Bar Act, the Dental Practice Act, and most other California licensing acts do not authorize LLC ownership. Licensed practices in California must form Professional Corporations under the Moscone-Knox Professional Corporation Act (Corporations Code §13400 et seq.). A Professional Corporation can elect S-Corp federal taxation. Many California medical and dental practices operate as PCs with an S-Corp federal election. The S-election does not change California's state-level franchise tax structure, only the federal pass-through treatment.

How do I make an S-Corporation election?

File IRS Form 2553 within two months and 15 days of the start of the tax year in which the election is to take effect (or any time during the prior tax year). All shareholders must consent. The election is federal only; California honors the S-election but charges the 1.5 percent franchise tax on net income (with the $800 floor). The S-election is revocable but can only be reinstated five years later, so the decision is not casual. Late S-elections can sometimes be cured under Rev. Proc. 2013-30 if the failure was inadvertent and the entity acted consistently with S status.

Decision framework: which entity is right for you?

Three questions filter most decisions. First, is the business a licensed professional service? If yes, it must be a Professional Corporation in California. PCs typically elect S-Corp federal taxation. Second, will the business raise priced equity from outside investors or VCs? If yes, a Delaware C-Corp is almost always the answer (with California foreign qualification). If no, the LLC vs. S-Corp choice depends on self-employment tax math. Third, is the business profitable enough that the S-Corp salary-vs-distribution savings exceed the cost of running payroll? If yes, S-Corp election makes sense. If no, LLC simplicity wins. For real estate, separate LLCs per property remain the dominant choice.

Who can legally own a medical spa in California?

Three categories. First, a California-licensed physician operating as a sole proprietor (allowed, though rarely used because of liability exposure). Second, a Professional Corporation under Moscone-Knox owned at least 51 percent by California-licensed physicians and surgeons. Third, a multi-owner PC where physicians hold at least 51 percent and allied licensees on the §13401.5 list hold up to 49 percent, with the count of allied owners not exceeding the count of physician owners. Outside these three structures, no one can own a California medical spa.

Can a non-physician own a medical spa in California?

Not the clinical entity. Under California Business and Professions Code §2400, a corporation or non-licensed individual has no professional right or power to practice medicine. A non-physician can own a Management Services Organization that provides administrative support to a physician-owned PC under a Management Services Agreement. The MSO can be wholly owned by non-physicians. The MSO cannot make clinical decisions, hire or fire physicians for clinical reasons, control medical records, or share in clinical revenue without fair market value documentation. The MSO arrangement is the only legal path for non-physician capital.

Can a nurse or nurse practitioner own a medical spa in California?

Partially. A nurse practitioner, registered nurse, or physician assistant can own a minority interest of up to 49 percent in a California medical PC under Corporations Code §13401.5. They cannot hold a majority. Nurse-only ownership of a medical spa, even with a paid 'medical director' physician hired on the side, is the most-enforced violation by the California Medical Board. The Medical Board has stated this position in its published Bottom Line: Medical Spas guidance: nurses cannot set up a medical practice in a salon and hire a supervising physician. Doing so aids the unlicensed practice of medicine under BPC §2264.

Can private equity own a California medical spa?

Only through an MSO. Private equity funds, family offices, and corporate investors cannot own equity in the clinical PC. They can own the MSO entity that the PC contracts with. This is the structure most PE-backed med spa platforms use. The PE-owned MSO charges the PC a fair market value management fee (documented annually). The MSO cannot exercise clinical control. The PE fund cannot have any direct power to terminate physicians for clinical reasons, set clinical protocols, or take a percentage of clinical revenue without FMV support. The CPOM line is bright. The structure works if it is drafted and operated tightly.

Why does California prohibit non-physician ownership of medical practices?

The policy rationale traces back to People v. Pacific Health Corp., 12 Cal.2d 156 (1938). The California Supreme Court held that allowing a general business corporation to practice medicine would let commercial interests interfere with physician judgment, drive volume over quality, and prioritize shareholder returns over patient outcomes. The Medical Board's published position reinforces this. The doctrine exists to keep clinical decisions in the hands of people who answer to a medical license, who are bound by ethical obligations to put the patient first, and who fall under Medical Board enforcement jurisdiction. A business corporation does not.

Comparison: legal vs illegal medical spa ownership structures in California

What does the Medical Board look for in an ownership audit?

• Articles of incorporation: is the entity a Moscone-Knox PC, or is it an LLC or general corporation?
• Stock ledger: do California-licensed physicians hold at least 51 percent? Are allied owners on the §13401.5 list?
• Statement of Information: are all named directors and officers licensed (except asst. sec/treas)?
• Bylaws: do they vest clinical authority in physician-owners?
• MSA: does it limit the MSO to non-clinical services? Is the fee at FMV?
• Patient records ownership: does the PC control the EHR contract?
• Advertising: does the spa name a licensed supervising physician on its website, intake forms, and ads (BPC §651)?
• Standardized procedures: do they exist, are they specific to each delegated treatment, and do they comply with 16 CCR §1474?

What if the spa has been operating with non-compliant ownership?

It can usually be restructured. The typical fix involves forming a new compliant PC, transferring clinical operations and assets to it, executing a compliant MSA between the PC and a separate MSO, retitling the medical equipment and the EHR contract, updating advertising and intake materials, and filing the corporate changes with the Secretary of State and the Medical Board. Existing patient records transfer to the new PC. The non-compliant entity is wound down or repurposed as the MSO. Done before an enforcement action arrives, the restructure is straightforward. Done in response to a Medical Board inquiry, the firm becomes a defense exercise rather than a clean transition.
