Information on ABA Coverage and Insurance

Hi All,
For my next blog, I decided to share some important information about health-insurance coverage for autism services. The financial cost of autism care can be significant, especially for individuals who require intensive support. Private insurance may help cover these expenses, but coverage depends on the type of insurance plan, medical necessity requirements, and the state and federal laws that apply.
Insurance can be complicated and confusing, so my best advice is: Know your plan, know the law, and know your rights!
Autism Speaks provides helpful information about health-insurance coverage for autism and Connecticut’s state-regulated insurance requirements.
I have also included an Autism Speaks resource for self-funded employer health plans. It includes sample letters that families can customize when asking an employer’s Human Resources department to add or improve coverage for autism services, including Applied Behavior Analysis (ABA).
1. What is the history of Connecticut’s autism insurance law?
Connecticut’s autism insurance law, Substitute Senate Bill 301/Public Act 09-115, was enacted on June 9, 2009, and became effective January 1, 2010. Connecticut later issued Insurance Bulletins HC-96 and HC-99 in 2014, removing the former age and annual dollar caps on ABA coverage.
2. Which insurance plans are subject to Connecticut’s autism insurance requirements?
The law generally applies to:
ACA-compliant individual plans
Fully insured large-group plans
Fully insured small-group plans
Certain state-regulated health plans
Grandfathered individual plans may be exempt.
It is especially important to determine whether an employer’s plan is fully insured or self-funded. Fully insured plans are generally subject to state insurance laws. Self-funded employer plans are primarily regulated by federal law and may not be required to follow Connecticut’s insurance mandate.
Ask your employer or insurance company:
Is my plan fully insured or self-funded?
Which state regulates the plan?
Is ABA a covered benefit?
Are prior authorization or medical necessity reviews required?
Can I receive a copy of the Summary Plan Description?
3. Which autism-related services may be covered?
Connecticut’s requirements include coverage for medically necessary autism diagnosis and treatment, including:
Diagnostic evaluations
Behavioral therapy, including ABA
Prescription medication when prescription coverage is included in the plan
Psychiatric and psychological services
Speech therapy
Occupational therapy
Physical therapy
Coverage generally must follow an individualized treatment plan and meet the insurance plan’s medical-necessity and provider requirements.
4. Are there age limits or annual dollar caps?
The old annual limits of $50,000, $35,000, and $25,000 are no longer current. Connecticut removed those age-based dollar caps in 2014.
Currently, Connecticut law defines covered behavioral therapy as therapy provided to individuals under age 21. Beginning January 1, 2027, the age limit will increase to individuals under age 26 under Public Act 25-3.
Plans may still require prior authorization, periodic treatment-plan reviews, documentation of medical necessity, and the use of qualified providers. Families should carefully review their specific plan documents because coverage rules can vary.
5. Where can families find additional information?
Families can review:
6. What does “behavioral therapy” include?
Connecticut law defines behavioral therapy as interactive behavioral treatments supported by evidence-based research. This includes Applied Behavior Analysis, Cognitive Behavioral Therapy, and other therapies supported by research for treating individuals diagnosed with autism spectrum disorder.
If coverage is denied, ask the insurance company for the denial and the specific plan provision in writing. Families may also request information about internal appeals, external reviews, and mental-health parity protections.
This information is intended for educational purposes and is not legal advice. Insurance laws and individual plan requirements can change, so families should confirm their benefits directly with their insurer, employer, or a qualified advocate.
