This set of seven issue briefs considers six important community-based services for children with serious mental or emotional disorders that some states provide as mandated rehabilitation services under the federal Medicaid law. The materials are designed to help state policymakers develop appropriate rules for covering community-based services for this population. Following a brief introduction, the first brief offers a general discussion of issues involved in funding child mental health services through Medicaid, such as Medicaid reimbursement as part of overall state mental health policy. Each of the six numbered issue briefs lists the goals and purposes of a service, describes research to support its effectiveness and provides a composite definition of the activities covered, drawn from one or more state definitions as approved by the federal government. Also given is information on state definitions of qualified providers, lengths of treatment, prior approval and other factors. The six briefs address the following issues: (1) behavioral/therapeutic aids; (2) intensive in-home services; (3) child respite care; (4) after-school programs; (5) summer camps; and (6) therapeutic nurseries and preschools.
