Health care coverage: mental health or substance use disorders.

Existing law, the Knox-Keene Health Care Service Plan Act of 1975, provides for the licensure and regulation of health care service plans by the Department of Managed Health Care and makes a willful violation of the act a crime. Existing law also provides for the regulation of health insurers by the Department of Insurance. Existing law authorizes health care service plans and health insurers that cover prescription drugs to utilize reasonable medical management practices, including prior authorization and step therapy, consistent with applicable law. This bill would prohibit a health care service plan contract or a health insurance policy that is issued, amended, or renewed on or after January 1, 2027, from imposing step therapy as a prerequisite to authorizing coverage of any prescription drug used for the treatment of a serious mental illness or substance use disorder, as those terms are defined, except as specified. The bill would specify that the prohibition on step therapy does not apply when the United States Food and Drug Administration-labeled indications and usage of a drug indicate that some prior medication must be taken. Because a willful violation of this provision by a health care service plan would be a crime, the bill would impose a state-mandated local program. The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement. This bill would provide that no reimbursement is required by this act for a specified reason.
