While requirements can vary depending on your specific provider, the ADOS-2 (Autism Diagnostic Observation Schedule, Second Edition) is widely considered the gold standard and is accepted by most insurance companies. Most insurers require a formal diagnosis that includes standardized assessment results to demonstrate medical necessity for Applied Behavior Analysis (ABA).

In addition to the ADOS-2, insurers typically look for the following in a diagnostic report:

• Comprehensive Diagnostic Evaluation: A report from a licensed psychologist, developmental pediatrician, or neuropsychologist that confirms an autism spectrum disorder diagnosis using DSM-5 criteria.
• Developmental History: Detailed clinical observations and a thorough history of your child’s development.
• Medical Necessity Letter: A letter from the diagnosing provider or BCBA that connects your child’s deficits directly to measurable treatment goals and recommended therapy hours.

Some insurance plans may accept other tools, such as the ADI-R (Autism Diagnostic Interview-Revised) or CARS (Childhood Autism Rating Scale), though these are sometimes required as supplements rather than standalone assessments.

We provide white-glove service during our intake process to review your existing records and pinpoint any missing documentation. Our goal is to ensure your submission meets all payer requirements to avoid delays in starting high-quality ABA therapy. Because insurance coverage varies by plan, we recommend you verify your specific benefits with your insurer before beginning services.

Consult your licensed BCBA or healthcare professional for individualized assessment and recommendations. Results may vary and individual outcomes are not guaranteed.
