This report describes the Home and Community Based Services (HCBS) Waiver to section 1915 (c) of the Federal Social Security Act that was obtained by the New York State Office of Mental Health. The HCBS Waiver affects the services provided to children and adolescents with serious emotional disturbances. Three statutory requirements are included in the HCBS Waiver: (1) the statewide and comparability requirements were waived to allow the implementation of the HCBS Waiver on a demonstration basis in seven counties and the five boroughs of New York City; (2) the requirements relating to amount, duration, and scope of services were waived which makes it possible to offer six new Medicaid services (individualized care coordination, respite care, skill building services, intensive in-home services, crisis response services, and family support services) in addition to existing Medicaid services; and (3) a requirement relating to the parental deeming rule was waived, which allows the parents' income and resources not to be considered when determining a child's eligibility for Medicaid. The report outlines the goals of the HCBS Waiver, the target population, the local infrastructure in each waiver site, and the HCBS Waiver services. A cost evaluation is also provided. (CR)
