November 24, 2025 | Sacramento, CA – MedLegalNews.com — California lawmakers are taking a bold step to protect physician autonomy and patient care as SB 351 and AB 1415 prepare to take effect on January 1, 2026. These landmark laws target private equity, hedge funds, and management services organizations (MSOs) exerting nonclinical control over medical practices.
SB 351 prohibits nonclinical investors from interfering with medical judgment. PE firms and hedge funds can no longer dictate diagnostic decisions, referrals, or patient care schedules. Any contract granting them this authority is considered void and unenforceable, and restrictive clauses like noncompete or non-disparagement agreements are invalidated.
The law goes further by clarifying what constitutes improper influence, giving regulators and courts clearer tools to evaluate questionable arrangements. It restricts financial leverage that pressures physicians to increase volume, follow predetermined care pathways, or prioritize investor returns over clinical need. Medical groups operating under MSO structures are required to reassess existing management agreements, compensation models, and delegated authority to ensure that no third-party entity has the ability to shape or override clinical decisions.
SB 351 also reinforces long-standing corporate practice of medicine rules, which have become increasingly strained as private equity-backed networks expand across high-demand specialties such as dermatology, primary care, behavioral health, and dental services. By providing explicit statutory guardrails, the law is meant to stabilize clinical decision-making environments and prevent subtle or indirect forms of nonclinical pressure from influencing patient care.
Shielding Physicians from Financial Pressure
SB 351 prohibits nonclinical investors from interfering with medical judgment. PE firms and hedge funds can no longer dictate diagnostic decisions, referrals, or patient care schedules. Any contract granting them this authority is considered void and unenforceable, and restrictive clauses like noncompete or non-disparagement agreements are invalidated. Together with AB 1415, which strengthens transparency and oversight requirements, these protections reinforce the state’s broader effort to curb financial pressure in clinical environments.
“California is setting a new standard for protecting clinical independence in the face of financial consolidation,” said health law analyst Dr. Serena Lopez.
Transparency Through AB 1415
AB 1415 complements SB 351 by imposing reporting and transparency requirements on entities with financial stakes in healthcare practices. MSOs and investment groups must disclose significant transactions and governance changes to the California Office of Health Care Affordability (OHCA), allowing regulators to assess the impact on patient care, cost, and workforce stability.
Compliance and Oversight: What Practices Must Know
Healthcare practices backed by private equity or similar investors should review contracts immediately to ensure compliance. Violations can result in enforcement action and potential legal liability. The law aims to balance financial investment with patient safety and provider autonomy, a priority in the era of growing healthcare consolidation.
