No, not every state or insurance plan follows a universal autism insurance mandate. While a majority of states have enacted some form of mandate requiring health plans to cover autism diagnosis and treatment, the regulations and their reach vary significantly.

Key factors regarding the availability of these mandates include:

• Variations by State: Mandates differ regarding age limits and coverage caps. For example, Maryland covers individuals up to age 21, Arizona up to age 16, and Utah has a more limited mandate covering children only up to age 9.
• Exemptions for Self-Funded Plans: Many large employers offer self-funded health plans regulated by federal ERISA laws rather than state laws. These plans are generally exempt from state autism insurance mandates, although some employers may choose to provide coverage voluntarily.
• Types of Coverage: State mandates typically apply to state-regulated (fully insured) private plans and may have separate requirements for Medicaid.

Because coverage is a “patchwork” across the country and a mandate does not guarantee a specific child’s coverage, families are encouraged to verify their unique benefits directly with their insurance provider.
