ABA Therapy Denials Are Among the Most Contested — andMost Overturnable

Applied Behavior Analysis therapy is the most widely used and evidence-supported treatment for autism spectrum disorder. It is also one of the most frequently denied insurance benefits in the country. If your child's ABA therapy was denied, the Mental Health Parity Act and decades of legal precedent are on your side.

Why ABA Therapy Is Denied

• The insurer classifies ABA as "educational" rather than "medical" — an argument that has been rejected by courts and regulators
• The insurer claims ABA is "experimental" or "investigational" — a position that conflicts with the scientific and medical consensus
• The insurer limits ABA hours more strictly than comparable physical therapies
• The insurer denies based on lack of prior authorization or incomplete documentation
• The insurer claims the child is too high-functioning to qualify — without clinical basis

The Law Is on Your Side

Mental Health Parity Act

If your plan covers physical therapy or occupational therapy without hour limits, it cannot limit ABA therapy more restrictively. Applying stricter limits to ABA than to comparable physical therapies is a parity violation.

State ABA mandates

Most states now have laws requiring insurance coverage of ABA therapy for autism spectrum disorder. Some states set minimum coverage hours. Check your state's insurance mandate — your insurer maybe in direct violation.

Medical consensus

The U.S. Surgeon General, the American Academy of Pediatrics, and virtually every major medical authority recognize ABA as medically necessary for autism treatment. The "experimental" argument has been rejected in litigation consistently.

What Your Appeal Needs

A comprehensive diagnosis and treatment plan

Your child's diagnosis of autism spectrum disorder, the ABA treatment plan prepared by a Board Certified Behavior Analyst (BCBA), and treatment records documenting progress and goals.

Medical necessity letter from the diagnosing physician and BCBA

Both the prescribing physician and the treating BCBA should provide letters documenting why ABA is medically necessary, what goals are being addressed, and the clinical consequences of discontinuing treatment.

Parity analysis

Identify comparable physical health therapies in your plan that are not subject to the same hour or authorization restrictions. Document the disparity explicitly.

State mandate citation

If your state has an ABA mandate, cite the specific statute in your appeal letter.
