An act to add Section 1371.45 to the Health and Safety Code, to add Section 10112.76 to the Insurance Code, and to add Section 14133.87 to the Welfare and Institutions Code, relating to health care coverage.
AB 384, the California Mental Health Protection Act, would prohibit prior authorization requirements for medically necessary inpatient admissions for mental health disorders, substance use disorders, and co-occurring disorders. Beginning with health plan contracts and health insurance policies issued, amended, or renewed on or after January 1, 2027, health care service plans and health insurers could not require prior authorization for admission to 24-hour inpatient care when a physician determines the care is medically necessary, and they could not require prior authorization for medically necessary services delivered during that admission.
The bill applies the same rule to Medi-Cal, barring prior authorization for qualifying inpatient admissions and related services for beneficiaries receiving mental health or substance use disorder treatment. It also defines covered inpatient settings broadly to include general acute care hospitals, acute psychiatric hospitals, psychiatric health facilities, chemical dependency recovery hospitals, and psychiatric residential treatment facilities. Enforcement authority is given to the Department of Managed Health Care, the Insurance Commissioner, and the Department of Health Care Services, including administrative penalties, civil penalties, contract termination, and sanctions for violations. The Medi-Cal provisions would apply only if federal funding and approvals are available, and the bill states that no state reimbursement to local agencies is required.
The overall sentiment reflected in the available legislative history is favorable. The bill received a unanimous 13-0 do-pass vote in committee, suggesting broad support for reducing administrative barriers to urgent behavioral health inpatient care. The absence of recorded committee testimony in the provided materials limits insight into detailed stakeholder positions, but the vote pattern indicates the measure was viewed positively by the committee.
The main point of contention, based on the bill’s structure rather than recorded debate, is the elimination of prior authorization, which insurers and managed care plans often use to control utilization and costs. Supporters are likely to view the bill as improving timely access to mental health and substance use treatment, while opponents or cautious stakeholders may be concerned about reduced utilization management, potential cost increases, and operational impacts on health plans and Medi-Cal managed care entities. The bill’s Medi-Cal provisions also depend on federal approval, which could affect implementation timing and scope.
AB 384 would add new sections to the Health and Safety Code, Insurance Code, and Welfare and Institutions Code to create a statewide prohibition on prior authorization for medically necessary inpatient behavioral health admissions and related inpatient services. It would affect commercial health care service plans, health insurance policies, and Medi-Cal managed care and prepaid health plans, while giving state regulators new enforcement tools. The bill would also create a state-mandated local program only in the limited sense described in the bill text, but it declares no reimbursement is required.
The available legislative record shows strong support and little visible opposition at the committee stage. The bill advanced on a 13-0 vote, which suggests the measure was broadly acceptable to committee members and likely framed as a patient-access and mental health parity issue. No committee transcript was provided, so the record does not show detailed arguments, but the vote indicates a favorable overall sentiment.
The central policy tension is between improving access to urgent inpatient mental health and substance use treatment and preserving insurer utilization controls. Health plans, insurers, and Medi-Cal managed care entities may be concerned that removing prior authorization could increase admissions, costs, and administrative burden, while supporters are likely to argue that prior authorization can delay necessary care during behavioral health crises. A secondary issue is implementation in Medi-Cal, which is contingent on federal financial participation and federal approvals, creating possible uncertainty about timing and scope.
