How to Get an Autism Diagnosis in New Mexico

Getting an autism diagnosis can feel overwhelming, but you don’t have to navigate it alone. At Mariposa Autism Service Center (MASC) in Southern New Mexico, we help families understand the process, connect with qualified providers, and take the first step toward supportive, individualized services.

Whether your child is a toddler, school-age, or teen, an accurate diagnosis is the key to accessing evidence-based therapies like ABA, speech therapy, and occupational therapy that help children learn, grow, and thrive.

What Is an Autism Diagnosis?

An autism diagnosis confirms that a child meets the criteria for Autism Spectrum Disorder (ASD) based on developmental history, behavioral observations, and standardized assessments. In New Mexico, this is known as a Stage 1 Diagnosis.

A Stage 1 diagnosis must:

  • Clearly state “Autism Spectrum Disorder”
  • Include results from a standardized autism screening or assessment tool
  • Describe how autism affects your child’s daily life and development

Who Can Provide an Autism Diagnosis in New Mexico?

Many professionals can evaluate and diagnose autism, including:

  • Developmental pediatrician
  • Child psychologist or psychiatrist
  • Trained primary care provider (per New Mexico guidelines)

However, to access insurance-covered autism services (including ABA therapy through Turquoise Care and most private insurance), the diagnosis must come from or be confirmed by a Stage 1 diagnostician. MASC can help connect you with trusted local providers who meet these criteria.

How to Start the Process

  1. Watch for Developmental Signs
    Early signs of autism may appear before age two and can include:
  2. Limited or no eye contact
  3. Delays in speech or communication
  4. Repetitive movements or behaviors
  5. Sensory sensitivities
  6. Difficulty with social interaction
  7. Contact Your Pediatrician
  8.  If you have concerns, your child’s pediatrician can refer you to a specialist for a full evaluation.
  9. Schedule a Comprehensive Evaluation
  10. This may include parent interviews, play-based assessments, and questionnaires to gather a full picture of your child’s strengths and challenges.
  11. Obtain Written Documentation
  12. The final diagnostic report should be kept on file you will need it for insurance verification and service enrollment.

Why an Early Diagnosis Matters

Research shows that early intervention can significantly improve communication, social skills, and daily living abilities in children with autism. The sooner a child begins therapy, the more opportunities they have to build independence and confidence.

Once you have a diagnosis, MASC can guide you through:

  • Insurance verification for ABA therapy and other services
  • Enrollment in ABA, speech therapy, occupational therapy, and social skills groups
  • Parent training to support progress at home
  • Flexible scheduling with in-person and telehealth options
