Developmental Screening for Autism


When to screen: 18 and 24 month well-child visits

Symptoms of Autism Spectrum Disorder often become apparent around the child’s first year, and can be identified by 18 months. This screen has two stages. First, a 20-item questionnaire helps identify children at risk for Autism Spectrum Disorder. The second stage is a short follow-up interview completed immediately after the initial screen with the family in order to reduce the number of false positive results.

Louisiana Medicaid reimburses for autism screens using code 96110. Please refer to the bulletin and fee schedule for more information.
