DDD Explanation

The Division of Developmental Disabilities (DDD) is part of Arizona’s Department of Economic Security (DES). DDD’s purpose is to support people who develop severe and/or chronic disabilities before their eighteenth birthday. These disabilities limit a person’s ability to do the tasks related to daily living. A person may be eligible to receive developmental disability, or DDD services, if they have a diagnosis of:

  • Cognitive/Intellectual disability
  • Epilepsy
  • Cerebral palsy
  • Autism
  • Developmental delays

Mercy Care Plan provides medical services to more than 13,000 members in the DDD program. In addition, children under age three who have developmental delays are also eligible for the Arizona Early Intervention Program. Early intervention is a process in which a group of therapists and educators works with parents and families of children with special needs to support a child’s growth, development and learning.

If your child is older than three years and you or your child’s PCP suspect developmental delays, call Member Services at (602) 263-3000 and ask for the DDD Liaison to talk about services that may be available.
