305 ILCS 5/5-39: Behavioral health services for children; diagnostic assessment system.

Beginning on July 1, 2022, if it is necessary to provide a diagnostic code for behavioral health services for children ages 5 and under, providers shall utilize a developmentally appropriate and age-appropriate diagnostic assessment system, such as the Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood-Revised (DC:0-5), for diagnosis and treatment planning. If necessary for billing purposes, the provider, managed care organization, or Department shall utilize the existing crosswalk tool to convert the developmentally appropriate and age-appropriate diagnosis code to the relevant code available in the State system.

By no later than January 1, 2022, the Department shall make recommendations to the General Assembly on the resources needed to integrate developmentally appropriate and age-appropriate diagnostic codes into the State system.
