What L.A. Physicians Need to Know About New California Health Care Laws Now in Effect

A broad slate of new California health care laws took effect January 1, 2026, bringing meaningful changes to how physicians practice medicine and how patients access care. Many of the measures were sponsored or strongly supported by the California Medical Association and reflect priorities long championed by physicians: protecting clinical judgment, reducing unnecessary administrative burden, and preserving access to essential care.

For Los Angeles physicians working in one of the nation’s most complex healthcare environments, these changes have immediate relevance across practice settings and specialties.

New protections around artificial intelligence

As artificial intelligence becomes more visible in clinical and patient-facing settings, AB 489 (Bonta) establishes clear guardrails. The law requires disclosure when AI tools are used in interactions with patients and prohibits systems from misrepresenting themselves as licensed medical professionals.

With Los Angeles home to major health systems, digital health companies, and technology-enabled care models, the law aims to protect patient trust and prevent confusion. It reinforces a foundational principle: technology may support care, but it cannot impersonate a physician or obscure who is making clinical decisions.

Safeguarding independent physician judgment

SB 351 (Cabaldon) responds to growing concerns about private equity and corporate influence in medicine by reinforcing California’s long-standing ban on the corporate practice of medicine. The law strengthens enforcement mechanisms and empowers the Attorney General to take action when entities improperly interfere with physician clinical judgment.

For physicians practicing in increasingly consolidated and complex organizational structures, particularly in Los Angeles County, the law underscores that business interests cannot dictate patient care. Clinical decisions must remain in the hands of licensed physicians, regardless of employment or management arrangements.

A new approach to reducing prior authorization

Administrative burden remains one of the most persistent challenges facing physicians. SB 306 (Becker) introduces a significant shift by giving regulators new authority to eliminate certain prior authorization requirements statewide on a code-by-code basis.

Rather than addressing prior authorization plan by plan, the law allows the Department of Managed Health Care and the Department of Insurance to remove authorization requirements where evidence shows they do not improve care. While not an immediate fix, the law creates a pathway for meaningful reduction in delays that affect imaging, procedures, and specialty care.

Expanded access to essential services

Several additional laws now in effect directly impact patient access and affordability.

AB 144 protects vaccine access by allowing California public health officials to maintain broad immunization coverage requirements even if federal guidance narrows. This helps ensure patients continue receiving recommended vaccines without new cost-sharing barriers, an important safeguard in a county as large and diverse as Los Angeles.

For patients with diabetes, SB 40 (Wiener) eliminates deductibles for prescription insulin under state-regulated plans and caps out-of-pocket costs at $35 for a 30-day supply. The state’s CalRx program is also expanding access to generic insulin pens at a recommended price of $11 per pen, addressing one of the most common medication affordability challenges physicians encounter.

Access to reproductive care is expanded under SB 729 (Menjivar), which requires large group health plans issued on or after January 1, 2026, to cover infertility diagnosis and treatment, including in vitro fertilization. For Los Angeles physicians caring for patients seeking fertility services, the law represents a significant shift in coverage and patient options.

Tools to help physicians stay informed

To support physicians as these changes take effect, CMA has released its annual report, “Significant New California Laws of Interest to Physicians for 2026.” The guide provides practical summaries of the most important new laws and is available at no cost.

CMA will also host a live webinar, New Laws Affecting Physicians 2026, on January 27, 2026, from 12:15 to 1:15 p.m. The program will review key provisions, highlight pending legislation, and outline legal resources available to physicians. The webinar will be presented by Sheirin Ghoddoucy, senior legal counsel and director of legal advocacy for CMA, and is free to CMA members and their staff.
