Understanding Missouri's ABA Insurance Mandate
Missouri law requires many health insurance plans to cover applied behavior analysis (ABA) therapy for individuals diagnosed with autism spectrum disorder. This mandate, part of the state's autism insurance reform, ensures families have access to evidence-based treatment. However, not all plans are equal, and knowing your specific rights is crucial.
Who Is Covered?
The mandate applies to children under 21 years old who have a diagnosis of autism. There is no maximum age limit for the diagnosis itself, but coverage typically ends at age 21. The law applies to state-regulated health plans, including those purchased through the individual market, small group plans, and large group plans.
What Does the Mandate Cover?
Coverage includes ABA therapy, which is a scientifically proven approach to improve communication, social skills, and behavior. The mandate requires plans to cover up to $72,000 per year for ABA services. This cap is adjusted annually for inflation. Plans must also cover diagnostic assessments, treatment plans, and ongoing supervision by a Board Certified Behavior Analyst (BCBA).

Types of Insurance Plans and Their Obligations
Not all insurance plans are subject to the state mandate. Understanding your plan type is the first step to accessing coverage.
State-Regulated Plans
Most plans sold in Missouri, including those on the health insurance marketplace, are state-regulated and must comply with the mandate. This includes plans from major insurers like Anthem Blue Cross Blue Shield, Cigna, and UnitedHealthcare.
Self-Funded Employer Plans (ERISA)
Many large employers self-fund their health plans, meaning they pay claims directly rather than buying insurance. These plans are governed by federal law (ERISA) and are not required to follow state mandates. Check your plan documents or contact your HR department to see if your plan is self-funded.
Medicaid (MO HealthNet)
Missouri's Medicaid program, MO HealthNet, covers ABA therapy for eligible children under 21. Coverage is comprehensive, with no annual cap, but requires prior authorization and a diagnosis of autism. Families enrolled in Medicaid can access BCBA-led therapy through approved providers.
How to Verify Your Coverage
Before starting ABA therapy, verify your benefits to avoid unexpected costs.
Step-by-Step Guide
- Call the customer service number on your insurance card.
- Ask: 'Does my plan cover ABA therapy for autism? Is there a deductible, copay, or coinsurance?'
- Request the annual and lifetime coverage limits.
- Ask if you need prior authorization or a referral.
- Confirm if the provider must be in-network.
Common Coverage Details
Many plans require a deductible before coverage kicks in, typically $1,000 to $5,000. After that, you may pay a copay (e.g., $20 per session) or coinsurance (e.g., 20% of the cost). Some plans have a separate ABA benefit with different cost-sharing.

What to Do If Your Claim Is Denied
Denials are common but can be appealed. Missouri law requires plans to provide a clear reason for denial and a process to appeal.
Steps to Appeal
- Review the denial letter for the specific reason (e.g., not medically necessary, out-of-network).
- Gather supporting documents: diagnosis letter, treatment plan from a BCBA, and letters of medical necessity.
- File an internal appeal with your insurance company within the timeframe (usually 180 days).
- If denied, request an external review by an independent third party. Missouri's Department of Insurance can assist.
Tip: Work with your provider's billing team. They often have experience with appeals and can provide the necessary clinical justification.
