This toolkit provides a reminder to States that EPSDT requirements extend to behavioral health care. The toolkit is organized around four main sections, each containing actionable strategies and sub-strategies for state Medicaid and CHIP agencies: (1) developing and supporting a behavioral health care delivery system that can meet a range of children’s needs; (2) promoting early intervention for children’s behavioral health conditions; (3) improving children’s access to behavioral health care through service coordination and integration; and (4) increasing the workforce capacity for children’s behavioral health services. Throughout, CMS includes state examples to demonstrate implementation approaches — a welcome expansion on top of past guidance for states looking for state models to draw from.
