Collaboration between Medicaid and juvenile justice system is important to addressing the barriers to physical and mental health coverage and care for juvenile justice-involved youth. A strong partnership between these agencies is critical to more effectively meeting the health needs of this population. Educating juvenile justice agencies and staff about Medicaid policies is important because the Medicaid program can finance mental and physical health services for juvenile justice-involved youth in certain placements, as well as being an important way for youth to receive services once they transition out of the system. The collection of information about the population served by both agencies can help inform agencies about the health needs of these youth.
