Health coverage: mental health and substance use disorders. This bill would require a health care service plan and a disability insurer, and an entity acting on a plan’s or insurer’s behalf, to ensure compliance with specific requirements for utilization review, including maintaining telephone access during California business hours for a health care provider to request authorization for mental health and substance use disorder care and conducting peer-to-peer discussions regarding specific patient issues related to treatment. Because a willful violation of these provisions by a health care service plan would be a crime, the bill would impose a state-mandated local program.
