Abstract

As the number of individuals diagnosed with autism increases, there is an increase in demand to provide support throughout their lifespan. This study aimed to: (1) estimate trends in the prevalence of autism diagnoses and medical services use in adults with autism diagnoses; (2) assess predictors of healthcare utilization and costs among adults with autism diagnoses enrolled in Medicaid. A retrospective analysis of 2006-2008 Medicaid claims for 39 states was conducted. There was a 38% increase in the prevalence of autism diagnoses from 2006 to 2008. Total expenditures and outpatient and ER visits varied significantly by demographic variables.
