Selling Your California Healthcare Practice: What the Law Permits, What It Doesn't, and What You Must Do Right

A Guide to Asset Sales, Stock Sales, Valuation, and the Rules That Make California Unique

_{This five-part blog series is for physicians, dentists, oral surgeons, chiropractors, therapists, optometrists, and every other licensed California healthcare provider who has built something worth protecting — and who has not yet taken the legal steps to protect it.}

For many California healthcare providers, the most straightforward succession plan is also the most lucrative: sell the practice. Used well, a practice sale converts decades of professional investment into a lump sum or structured payment stream that funds retirement, supports family, and rewards the provider for what they built.

But California's strict healthcare regulatory environment makes selling a medical or dental practice significantly more complex than selling any other type of business. The buyer pool is legally constrained. The structure of the transaction matters enormously. And getting the details wrong can result in a transaction that is void, unenforceable, or worse — a transaction that triggers regulatory consequences long after the sale is complete.

The Foundational Constraint: Who Can Buy Your Practice

California's Corporate Practice of Medicine doctrine, codified in Business and Professions Code Sections 2052 and 2400, and strengthened most recently by Senate Bill 351 (signed into law October 6, 2025), means that only specific categories of buyers may purchase and operate a California medical or dental practice:

•      A licensed physician or dentist (or group of same) organized as a California Professional Medical Corporation (PC) under the Moscone-Knox Professional Corporation Act (Corporations Code Section 13400 et seq.)

•      A nonprofit hospital or health system meeting the requirements of Health and Safety Code Section 1204

•      A licensed Health Maintenance Organization (HMO) or Health Plan under the Knox-Keene Act

•      A government healthcare entity

Non-physicians, private equity groups, hedge funds, and general business corporations cannot directly purchase and operate your California medical practice. This is not a technicality — it is an absolute prohibition, and SB 351 codified it into the California Health and Safety Code (new Section 1190) with Attorney General enforcement authority.

This constraint dramatically narrows your buyer pool relative to other types of businesses, and it is the single most important fact to understand when planning a practice sale.

Asset Sale vs. Stock Sale: Choosing the Right Structure

Every California practice sale involves a fundamental structural choice: sell the assets of the practice, or sell the shares of the professional corporation itself.

Asset Sale

In an asset sale, the buyer purchases specific items — equipment, furniture, patient lists (subject to HIPAA and California Confidentiality of Medical Information Act constraints), goodwill, the practice name, supplier contracts, and lease interests — while the selling entity (the professional corporation) is retained by the seller and wound down.

Benefits: The buyer gets a clean start without inheriting the seller's liabilities, contracts, or regulatory history. Many buyers prefer this structure for that reason. It can also create favorable tax treatment by allowing the buyer to step up the cost basis of acquired assets.

Drawbacks: Patient lists and goodwill are often the most valuable elements of a medical practice, and transferring them involves navigating California's strict patient privacy laws. Under the California Confidentiality of Medical Information Act (Civil Code Section 56 et seq.) and HIPAA, patient information cannot simply be transferred to a new owner without appropriate patient authorization and notification. The California Medical Association recommends written patient notification — ideally by certified mail — giving patients adequate time to transfer their care or authorize record transfer. This process takes time and resources. Additionally, an asset sale may not convey the value of payer contracts, which typically require re-credentialing with each insurer.

Stock Sale

In a stock sale, the buyer acquires the shares of the professional corporation itself, stepping into the seller's shoes as the corporate owner. The practice — its contracts, payer relationships, credentialing, and history — continues without interruption.

Benefits: Continuity. Payer contracts, hospital privileges, and credentialing may transfer with the entity, avoiding the months-long re-credentialing process that can interrupt revenue. For a buyer, this represents significant operational value.

Drawbacks: The buyer inherits all of the corporation's liabilities — disclosed and undisclosed. This includes any Medicare or Medi-Cal overpayment obligations, pending malpractice claims not covered by tail insurance, employment disputes, and undisclosed billing irregularities. Comprehensive due diligence is essential. Additionally, under Corporations Code Section 13406.5, if the selling shareholder is the sole licensed owner, the share transfer must be completed promptly to avoid regulatory jeopardy.

Practice Valuation: What Your Practice Is Actually Worth

Medical Economics and practice appraisal experts consistently identify that healthcare practice valuation involves multiple components, and that providers routinely underestimate or overestimate their practice's value without professional guidance. Key valuation factors include:

•      Goodwill — both personal goodwill (attached to you as an individual provider) and enterprise goodwill (attached to the practice itself). Personal goodwill is typically not transferable and generally receives more favorable capital gains treatment under the tax code.

•      EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) — the standard financial metric used in healthcare practice valuation.

•      Payer mix and contract terms — a practice heavily dependent on Medi-Cal reimbursement will value differently than one with a robust commercial payer mix.

•      Equipment value — current fair market value of clinical and administrative equipment.

•      Patient retention risk — how many of your patients follow you personally versus remaining with the practice.

Engage a certified healthcare practice appraiser before listing. Do not rely on informal estimates from brokers with an interest in the transaction.

Non-Compete Agreements: California's Unique Position

California Business and Professions Code Section 16600 broadly prohibits non-compete agreements in employment contexts. However, there is a significant and specific exception: non-compete covenants connected with the sale of a business are enforceable in California under BPC Section 16601.

This means that as part of a practice sale, the seller can be required to agree not to practice medicine in a defined geographic area for a reasonable period — protecting the buyer's investment in the goodwill of the practice. SB 351 expressly preserved this exception for sale-connected non-competes, even while restricting non-competes in private equity management contexts.

Benefits: For the buyer, enforceable protection of the patient base they purchased. For the seller, the non-compete expectation is typically priced into a higher sale value — buyers pay more when they know the seller will not immediately re-enter the market next door.

Drawbacks: Sellers must carefully negotiate the geographic scope and duration of any non-compete. An overbroad restriction can limit future practice opportunities for years. These provisions require careful drafting.

The Required Notices You Cannot Skip

Regardless of how a sale is structured, the selling physician must comply with notification requirements that cannot be delegated away or skipped:

•      Patient notification consistent with Medical Board of California guidance: written notice to patients specifying the final date of care, where records will be stored, and how to access them. The California Medical Association recommends certified mail with return receipt.

•      Medical Board notification if the practice is closing as part of the sale.

•      DEA notification: if retiring from practice, the physician must notify the local DEA office and return DEA 222 order forms.

•      Payer notification: all health plans, Medicare, and Medi-Cal must be notified of ownership or participation changes.

•      Malpractice tail coverage: the purchase and sale agreement must identify which party bears the cost of tail coverage, and the seller should contact their professional liability carrier immediately upon entering sale discussions.

Benefits and Drawbacks at a Glance

The Risk of No Plan

A practice with no succession plan has no sale. It has a closure. Closures recover a fraction of the value that a planned, structured sale would generate. If you are relying on the value of your practice to fund retirement — and most solo practitioners are — the absence of a succession plan is not merely an inconvenience. It is a retirement funding crisis waiting to happen.
