What is DDD?
DDD supports people who develop severe and/or chronic disabilities before their 18th 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 services if they have a diagnosis of:

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

Mercy Care provides medical services to more than 13,000 members in the DDD program. In addition, children under age 3, 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 an individual is older than 3 years and you and the primary care physician suspect developmental delays, call Member Services at 602-263-3000 or 1-800-624-3879 (TTY/TDD 711) and ask for the DDD representative to talk about services that may be available.

As a part of our Mercy 360 community reinvestment efforts, we have partnered with Touchstone Health Services, Southwest Behavioral & Health Services, and Southwest Human Development, to open four Autism Spectrum Disorders (ASD) treatment centers providing better access to care for our members and communities.

A Center of Excellence is a facility and/or program that is recognized as providing the highest level of leadership, quality and service. Through these partnerships, we are providing our members and their families with access to providers who are leaders in supporting individuals with ASD. These Centers of Excellence will help to provide:

  • An earlier diagnosis
  • Advanced coordination of care
  • Specialized services that drive holistic outcomes
  • Family and member advocacy and support
  • And, community education
