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 provides for the regulation of health insurers by the Department of Insurance. This bill would require a health care service plan or insurer to provide to each legal guardian of a patient, enrollee, or insured, 10 to 18 years of age, a written or electronic notice regarding the benefits of a behavioral health and wellness screening, as defined. The bill would require a health care service plan or insurer to provide the notice on an annual basis. Because a violation of the bill's requirements relative to a health care service plan would be crimes, 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.
