California Wellness Clinic Regulation in 2026: New AI Laws, the Carbon Health Settlement and Where Med Spa Law Stands

California is the most closely watched med spa market in the country, and it is where the most misinformation circulates. The most important correction first: California did not pass a med spa law in 2025 or 2026. What it did was tighten the rules around who controls medical practices, add AI rules for clinics, and show through an enforcement action what regulators think of friendly-PC structures. We cover the investor-control and sale rules in our post on selling a California med spa after SB 351 and AB 1415. This post covers everything else.

The Carbon Health Settlement

In June 2026 the California Attorney General announced a first-of-its-kind settlement with Carbon Health and its affiliated professional corporations over corporate practice of medicine violations. As reported, Carbon Health will pay $4.4 million and a co-founder $100,000, and must unwind its structure so that a non-medical management company does not own or control physician practices, along with fixing advertising, billing and consent forms. The settlement is subject to court approval, and Carbon Health is also in Chapter 11 bankruptcy. A separate settlement with a dental support organization, announced in May 2026, followed the same logic.

Law firms read these as signs of intensified scrutiny of management-company and friendly-PC models. That is commentary rather than a holding, but it is the clearest signal available about where California enforcement is looking. The core test is the one we describe in our MSO series: who actually decides, and does the physician-owned entity control the clinical side and the money.

AI Rules for Clinics

• AB 3030: effective January 1, 2025. Clinics must include an AI disclaimer and instructions for reaching a human on AI-generated clinical patient communications, unless a licensed clinician reviews the message.
• AB 489: effective January 1, 2026. AI tools may not imply they are licensed health professionals. Licensing boards, including the Medical Board, can enforce it, which affects AI chat, scheduling and marketing tools.
• AB 1979: signed September 30, 2026. Clinics must take reasonable steps so licensed clinicians keep independent judgment when using clinical decision support, AI may not independently perform functions that require a license, and health care chatbots are treated as providers under the state medical privacy law. It is a non-urgency bill, so it is generally expected to take effect January 1, 2027, but check the text.

Testosterone and CURES

AB 82, signed October 2025, stops testosterone and mifepristone prescriptions from being reported to the state's controlled substance database, and requires earlier records to be purged by January 1, 2027. It affects hormone and testosterone replacement clinics. Federal DEA telemedicine flexibilities for controlled substances, which cover testosterone, run through December 31, 2026, so plan for that deadline too.

Independent Nurse Practitioner Practice

The Board of Registered Nursing now lists an application for independent practice under AB 890, for a "104 NP" who has completed three years as a "103 NP." SB 1451, effective 2025, changed the transition-to-practice requirement and removed a patient notice requirement, though NPs must still disclose they are not physicians. Whether an independent NP can own a med spa or a professional nursing corporation, and how SB 351 and the state's health care transaction review apply to them, is unresolved in law-firm commentary. Do not assume it is allowed without counsel.

The Baseline Has Not Changed

The Medical Board's long-standing position is that medical spas offering medical procedures must be owned by physicians, that cosmetologists may not inject or use lasers, and that RNs and PAs work under physician supervision that is real rather than paper-only. That text is old, not new, and law-firm claims of new 2026 Board expectations on patient-specific orders or medical director engagement are not supported by primary sources we could find. See our California med spa CPOM guide.

GLP-1 Compounding and Peptides

A bill that would have set sourcing, testing and advertising rules for compounded weight-loss drugs, AB 1990, passed the Assembly but was held in Senate Appropriations in August 2026 and is dead for the session. Federal enforcement fills the gap: FDA's February 2026 statement and its warning letters on compounded GLP-1 marketing apply in California as everywhere. On peptides, an FDA advisory committee voted 8 to 6 in July 2026 to recommend adding BPC-157 to the 503A bulks list. That is advisory only and does not make it compoundable.

What a California Clinic Should Do

• Audit every AI tool that talks to patients and add required disclosures and human-contact instructions.
• Review your PC and MSO agreements against the control questions in the Carbon Health settlement and SB 351.
• If you prescribe testosterone, plan for the December 31, 2026 telemedicine deadline and the CURES change.
• Do not rely on blog claims of a California med spa registration law.
• If an NP owns or plans to own a clinic, get a California healthcare attorney's written view first.

Where MedGrid Fits

California requires a physician-owned professional corporation for the practice of medicine, so the MSO-PC structure is the lawful way to build a clinic here. MedGrid connects California clinics with a California-licensed physician, forms the PC and the management company, and keeps the structure clean: one physician per PC, revenue landing in the PC's own account, a flat fair-market management fee, separate agreements and independent counsel for the practice. Those are the points the Carbon Health case turned on. This describes how we build, not legal advice on your arrangement.

Frequently Asked Questions

• Did California pass a med spa law in 2025 or 2026?: We found none. Claims of a California med spa or IV registration law appear to confuse it with Indiana's SB 282.
• What was the Carbon Health settlement?: A June 2026 Attorney General settlement requiring the company to unwind a friendly-PC structure, subject to court approval.
• Do I have to disclose AI use to patients?: AB 3030 requires an AI disclaimer and human-contact instructions on AI-generated clinical communications unless a clinician reviews them, and AB 489 bars AI from implying licensure.
• Can a nurse practitioner own a California med spa?: It is unresolved. Independent practice exists, but ownership under corporate practice rules and SB 351 is unsettled.
• Is peptide therapy legal in California?: It depends on the specific peptide, sourcing and compounding status. FDA's advisory vote on BPC-157 is not a final decision.
