In California, about one in seven children are estimated to have special health care needs, which translates to at least 1.3 million young people across the state. Children and youth with special health care needs (CYSHCN) include infants, children and youth from birth to age 21 who have one or more chronic physical, developmental, behavioral or emotional conditions and require special health and support services. To better serve this population, the California Department of Public Health (CDPH), Maternal, Child and Adolescent Health (MCAH) Division collaborates with the California Department of Health Care Services (DHCS) and other partners to improve systems of care at the state and local level, promotes collaboration between agencies, and provides case management, family engagement, screening and links to services.
