A recent study of Medicaid in selected states finds that treated prevalence of ASD among youths aged 3 to 17 rose from 2.26 per thousand in 2001 to 3.39 per thousand in 2005. About two-thirds of these youths qualified for Medicaid either through SSI or a home-and-community-based waiver.
From the data in the selected states, the authors estimate that about 95,000 youths in the Medicaid system nationwide had an ASD diagnosis.
