This bill mandates that health insurance providers and the State Medicaid program in New Jersey cover medical expenses related to the screening, prevention, and treatment of behavioral health issues in children. It requires that claims for these services be accepted and reimbursed when using an "at-risk diagnosis," which is defined as a diagnosis that considers various factors affecting a child's behavioral health and development without leading to a formal mental health diagnosis. This provision aims to promote preventive care and allows providers to use alternative billing codes, including Social Determinants of Health Z-codes, for children aged 18 and younger.

Additionally, the bill stipulates that the State Health Benefits Commission and the School Employees' Health Benefits Commission must ensure that their contracts include similar coverage for behavioral health services. The bill emphasizes the importance of early identification and prevention of mental health conditions, allowing for a range of services such as screenings and psychotherapy for children who may not yet have a formal diagnosis. The act will take effect 90 days after enactment and will apply to all relevant policies and contracts issued or renewed thereafter.
