Intensive In-Home Services (IIH) are for youth under age 21. These are intensive therapeutic interventions provided in the youth’s residence (or other community settings as medically necessary) to improve family functioning, and significant functional impairments in major life activities that have occurred due to the youth’s mental, behavioral, or emotional illness in order to prevent an out of home placement, stabilize the youth, and gradually transition the youth to less restrictive levels of care and supports.
