If your child has been diagnosed with Autism Spectrum Disorder (ASD), you may have heard that you need a Comprehensive Diagnostic Evaluation Report before beginning Applied Behavior Analysis (ABA) therapy.
This can be confusing for many families. Often, parents know their child has autism but are unsure whether they have the type of documentation their insurance company requires to authorize ABA therapy.
This guide explains what a Comprehensive Diagnostic Evaluation Report is, why insurance companies require it, who can complete one, and what to do if you are unsure whether your child’s records meet the requirements.
What Is a Comprehensive Diagnostic Evaluation Report?
A Comprehensive Diagnostic Evaluation Report (sometimes called a Diagnostic Evaluation Report) is a detailed clinical assessment that explains how your child’s Autism Spectrum Disorder (ASD) diagnosis was determined.
Unlike a brief office note or diagnosis listed in a medical chart, this report is typically several pages long and contains the detailed clinical information insurance companies use to determine whether ABA therapy is medically necessary.
Why Do Insurance Companies Require This Report?
Before authorizing ABA therapy, most insurance companies require a Comprehensive Diagnostic Evaluation Report to:
- Confirm that your child meets the diagnostic criteria for Autism Spectrum Disorder.
- Understand how the diagnosis was made.
- Verify that ABA therapy is medically necessary.
- Review the clinical findings supporting treatment.
- Process the initial authorization request for ABA services.
Without this report, many insurance companies cannot approve ABA therapy.
What Is Included in a Comprehensive Diagnostic Evaluation Report?
Although reports vary by provider, they typically include:
- Medical and developmental history
- Parent interview
- Clinical observations
- Standardized autism assessment tools (when appropriate)
- Assessment of communication, social interaction, behavior, and developmental functioning
- Clinical findings supporting the diagnosis
- DSM-5 diagnostic conclusions
- Recommendations for treatment and services
- The evaluating provider’s signature and credentials
Who Can Diagnose Autism for ABA Therapy?
Requirements vary somewhat by insurance plan. However, insurance companies typically require the Autism Spectrum Disorder diagnosis to be completed or formally confirmed by one of the following provider types:
- Developmental-Behavioral Pediatrician
- Neurodevelopmental Pediatrician
- Child Neurologist
- Child or Adult Psychiatrist
- Licensed Clinical Psychologist
Some insurance plans also accept diagnoses completed or confirmed by:
- Pediatricians
- Family Medicine Physicians
- Internal Medicine Physicians
- Other physicians recognized by the insurance plan
Understanding the Different Types of Autism Evaluations
One of the biggest sources of confusion for families is that not all autism evaluations are treated the same by insurance companies.
In our experience, autism evaluations generally fall into one of three categories.
1. Comprehensive Diagnostic Evaluations That Are Usually Ready to Submit
These evaluations are typically completed and signed by one of the qualified medical providers listed above.
When the evaluation is comprehensive, includes a formal Autism Spectrum Disorder diagnosis, and is less than 36 months old, it is often sufficient to submit directly with an ABA authorization request.
Examples may include evaluations completed by:
- Developmental-Behavioral Pediatricians
- Child Neurologists
- Child Psychiatrists
- Licensed Clinical Psychologists
- Other accepted medical providers
2. Comprehensive Evaluations That Often Need a Qualified Medical Provider to Confirm the Diagnosis
This is one of the most common situations we see.
Some autism centers perform excellent, comprehensive evaluations using standardized autism assessment tools. These evaluations often contain detailed clinical observations and provide valuable information about a child’s strengths and needs.
One common example is an evaluation completed through Action Behavior Centers, although this situation can also occur with evaluations from other autism centers.
In many cases, these evaluations are clinically appropriate and extremely valuable, but they were completed by a provider who is not one of the medical provider types that some insurance companies recognize as qualified to formally diagnose Autism Spectrum Disorder for ABA authorization purposes.
Rather than repeating the entire evaluation, many insurance companies will accept these reports if they are reviewed by a qualified medical provider, such as:
- Developmental-Behavioral Pediatrician
- Neurodevelopmental Pediatrician
- Child Neurologist
- Child or Adult Psychiatrist
- Licensed Clinical Psychologist
- In some cases, a Pediatrician or another physician accepted by the insurance plan
That provider can review the evaluation, determine whether they agree with the findings, and formally diagnose or confirm the Autism Spectrum Disorder diagnosis.
In these situations, the original evaluation is not discarded—it often serves as the clinical foundation for the official diagnosis.
3. Evaluations That Generally Do Not Meet Insurance Requirements
Some documents are helpful pieces of your child’s history but are not considered comprehensive diagnostic evaluations for insurance authorization.
Examples include:
- A referral for ABA therapy
- A brief pediatrician office note
- An After Visit Summary (AVS)
- A diagnosis listed in the medical record without a comprehensive evaluation
- A school evaluation, ARD, or IEP
- Speech-language evaluations
- Occupational therapy evaluations
- Physical therapy evaluations
- A BCBA assessment
- An ABA intake assessment
- A treatment recommendation letter
These documents may indicate that your child has autism or would benefit from ABA therapy, but by themselves they generally do not provide the documentation insurance companies require to approve services.
How Recent Does the Evaluation Need to Be?
Many insurance companies require the Comprehensive Diagnostic Evaluation Report to have been completed within the past 36 months.
If your child’s evaluation is older than three years, your insurance company may require an updated evaluation before approving ABA therapy.
Not Sure Which Category Your Child’s Evaluation Falls Into?
Many families are unsure whether the records they have will satisfy their insurance company’s requirements.
The good news is that you do not have to figure this out on your own.
Our team reviews autism evaluations every day. We’ll gladly review your child’s existing documentation and let you know:
- Whether your evaluation is ready to submit to your insurance company.
- Whether it simply needs review and confirmation by a qualified medical provider.
- Whether a new comprehensive diagnostic evaluation will likely be needed.
If additional documentation is required, we’ll explain exactly what’s missing and help guide you through the next steps.
Frequently Asked Questions
My child already has an autism diagnosis. Why isn’t that enough?
Many children have an autism diagnosis documented in their medical record. However, insurance companies often require a Comprehensive Diagnostic Evaluation Report that explains how the diagnosis was made and supports the medical necessity of ABA therapy.
Is a pediatrician’s diagnosis enough?
Sometimes. Some insurance plans accept diagnoses completed or confirmed by pediatricians or other physicians. Others require the diagnosis to come from a developmental-behavioral pediatrician, neurologist, psychiatrist, or licensed clinical psychologist.
Is an evaluation from Action Behavior Centers enough?
It depends.
Many evaluations from Action Behavior Centers are comprehensive and contain valuable clinical information. However, if they were not completed by one of the provider types recognized by your insurance company to formally diagnose Autism Spectrum Disorder, the evaluation may need to be reviewed and confirmed by a qualified medical provider before ABA services can be authorized.
How old can the evaluation be?
Many insurance companies require the Comprehensive Diagnostic Evaluation Report to have been completed within the past 36 months.
What if I don’t have my child’s evaluation anymore?
That’s okay. Our team can often help you identify who completed the evaluation and assist you in obtaining a copy.
