From Diagnosis to ABA Therapy: What Families Should Know
Receiving an autism diagnosis for your child can bring a mix of emotions—and often, a lot of questions about what comes next. One of the first recommendations you may hear from your child's doctor is to start Applied Behavior Analysis (ABA) therapy. However, many parents are surprised to learn that a diagnosis alone isn’t always enough for insurance to approve services. The paperwork and requirements can feel confusing and overwhelming.
This guide is here to help you understand what insurance companies need, what to ask for during evaluations, and how to advocate for your child so they can access ABA therapy.
What Insurance Needs Beyond a Diagnosis
Most insurance companies require more than just an autism diagnosis to approve ABA therapy. They need specific documentation to confirm eligibility. While requirements vary by each individual plan, most plans expect:
A formal autism diagnosis from a developmental pediatrician, neurologist, or psychologist.
A referral or prescription for ABA therapy from the diagnosing doctor or pediatrician.
Standardized assessment results in a written summary with scoring included.
A Comprehensive Diagnostic Evaluation (CDE) in many cases.
If any of these documents are missing, insurance may delay or deny coverage.
What Is a Comprehensive Diagnostic Evaluation (CDE)?
A CDE is a thorough evaluation that confirms an autism diagnosis and provides the documentation insurance companies need to approve ABA therapy. A CDE “checks all the boxes” for insurance and typically includes:
A detailed developmental history (milestones, strengths, and challenges)
Parent interviews and questionnaires
Direct observation of your child’s behavior and interactions
Use of a standardized autism assessment and inclusion of impressions and scores
What Is a Standardized Autism Assessment?
A standardized assessment is a tool doctors use to measure autism-related symptoms in a clear, structured way. Unlike a brief observation or summary, these assessments follow set steps and scoring systems so the results are reliable — which is why insurance companies look for them. Think of it like school testing: instead of a teacher just saying “your child is doing well,” the teacher gives a test that shows exactly what skills your child has mastered and where they may need extra help. In the same way, a standardized autism assessment gives doctors measurable information about your child’s communication, social interactions, play skills, and behaviors.
For families, this means the evaluation report includes more than just a doctor’s opinion — it includes data that shows how your child meets the criteria for autism and why ABA therapy is medically necessary. Having this documentation helps prevent insurance delays and ensures your child can start services sooner.
Tip: Ask your child’s doctor which autism assessments they are using and confirm that the results will be included in the final written report.
Why Some Insurance Companies May Require Standardized Scores
In recent years, many insurance providers have become more strict about requiring standardized assessments for autism diagnoses. This isn’t to make things harder for families — it’s because insurance companies need measurable, objective data to show that ABA therapy is medically necessary.
Standardized scores provide a clear picture of your child’s strengths and challenges, which helps insurance reviewers see why intensive therapy hours are recommended. Without these scores, insurance may question the diagnosis or delay approval.
For families, this means that having standardized results included in the evaluation report can speed up the process and reduce the risk of denials.
Common Standardized Assessments Used in Autism Diagnoses
Doctors may use different tools, but these are the most commonly recognized by insurers:
ADOS-2 (Autism Diagnostic Observation Schedule): A play-based assessment with your child.
CARS-2 (Childhood Autism Rating Scale): A checklist rating the severity of autism symptoms.
GARS-3 (Gilliam Autism Rating Scale): A questionnaire for parents and caregivers.
M-CHAT-R/F (Modified Checklist for Autism in Toddlers, Revised with Follow-Up): A screening tool often used for young children (16–30 months) to identify autism risk.
SRS-2 (Social Responsiveness Scale, Second Edition): Measures social impairment associated with autism, based on parent or teacher reports.
Vineland Adaptive Behavior Scales: Measures daily living, communication, and social skills.
Not every insurance plan requires all of these, but at least one standardized assessment is usually necessary for ABA approval.
When Doctors Don’t Provide Standardized Assessments
It’s important for parents to know that not every neurologist or pediatrician will conduct standardized autism assessments as part of their evaluation. Some providers give only a diagnosis letter or short summary, which may not meet insurance requirements for ABA therapy.
If your child’s neurologist doesn’t include these assessments in the report, you may need to seek them from another professional such as a developmental pediatrician, licensed psychologist, or neuropsychologist. In some cases, families maybe need to pursue a private evaluation (often at an additional cost) to get the thorough documentation that insurance requires.
Because wait times for evaluations can sometimes be long, it’s best to confirm beforehand whether your doctor will complete a full diagnostic evaluation with standardized assessments. Asking early helps avoid delays and gives you time to explore other resources if needed.
Where families can look for standardized assessments:
Developmental pediatricians
Licensed child psychologists or neuropsychologists
University clinics or hospital-based autism centers
Private practices specializing in autism evaluations
Tip: When scheduling your child’s evaluation, ask directly, “Will this include a standardized autism assessment that insurance will accept for ABA therapy?”
Questions to Ask Doctors During an Autism Evaluation
It’s okay to advocate for your child’s needs. Consider asking:
Will this evaluation meet insurance requirements for ABA therapy?
Which standardized assessments will be included in the report?
Can I receive a full copy of the report?
Will the report include recommendations for ABA therapy?
Questions to Ask ABA Providers
When you’re ready to start ABA, ask potential providers:
Will you verify my insurance coverage and eligibility for ABA therapy?
Does my insurance require a Comprehensive Diagnostic Evaluation (CDE)?
Does my insurance require an autism diagnosis specifically for ABA services?
If I am paying privately, do I still need a diagnosis?
Can you help me understand where to go if my child still needs a CDE or standardized assessment?
Do you handle pre-authorizations and re-authorizations with my insurance?
How long does it usually take to start services once all documents are submitted?
Ongoing Follow-Ups: Why They Matter
After your child receives an autism diagnosis, it’s important to keep up with regular follow-up visits with their doctor — typically every 6–12 months. These appointments aren’t just routine check-ins; they serve several important purposes:
Allowing the doctor to review your child’s progress.
Confirming that autism symptoms still meet criteria for treatment.
Providing updated referral or prescription orders, since most insurance companies require them annually (and sometimes more often).
Ongoing documentation from your child’s doctor helps demonstrate continued medical necessity and ensures that insurance coverage for ABA therapy remains active without disruption.
Tip: Ask your doctor’s office to schedule your next follow-up before you leave, so you don’t risk gaps in documentation”
Advocating for Your Child
Remember, you can ask for what your child needs. If a doctor’s report is missing certain assessments, request an addendum or supplemental documentation. If insurance denies coverage, you can appeal with additional reports or letters of medical necessity.

Starting ABA therapy after an autism diagnosis can feel overwhelming, but understanding insurance requirements makes the process smoother. By asking the right questions, requesting the right documentation, and working with supportive providers, you can help your child access the services they need.
