Mental and Behavioral Health Parity Law

Mental health parity in health insurance coverage is a powerful tool for families of individuals with autism. Properly understood and put to work, it can result in better access to ABA treatment, shorter waitlists, and fewer claim denials.

What Is Parity?

Both federal and state laws prevent insurance plans from offering more favorable medical and surgical benefits than the mental and behavioral health benefits that it provides. That balance between the way medical and surgical benefits and mental and behavioral health benefits are treated by insurance carriers is called “parity.”

Parity Today

Parity in this context was formalized when the federal government passed the Mental Health Parity and Addiction Equity Act of 2008, also commonly written as MHPAEA. When MHPAEA was first signed into law, it applied only to large group health plans. It has since been expanded by the Affordable Care Act to apply to nearly every health plan.

The general rule under MHPAEA is:

“There can be no limitation on mental or behavioral health treatment if there is no such limitation on substantially all medical and surgical benefits in the same category.”

Dollar caps and session limits are quantitative treatment limitations that probably violate MHPAEA
Requiring Specific Assessment Tools (E.g. ADOS-2, ADI-R, CARS-2) Before Funding TreatmentWhile each of these assessments is widely used, no specific assessment tool is required for a valid diagnosis.

In fact, research supports the idea that an ADOS-2 is not needed to make an accurate diagnosis, and that the decision to administer it should be made by the diagnostician.
Blanket ABA Therapy Exclusion from PlanABA therapy is the generally accepted standard of care for insurance-funded autism intervention. Does this plan exclude treatments that constitute the generally accepted standard of care for substantially all outpatient medical and surgical benefits? If not, then this is a probable MHPAEA Violation.
