HB5196 Summary

• Amends the Mental Health and Developmental Disabilities Code to redefine "developmental disability" as a severe, chronic disability that results in substantial functional limitations in three or more major life activities, manifested before age 22, and requiring lifelong or extended services.

• Redefines "intellectual disability" to emphasize deficits in intellectual functioning (generally IQ of 70 or below) and adaptive functioning with onset during the developmental period, aligning with clinical assessment standards.

• Updates disability definitions across multiple state acts (Illinois Identification Card Act, School Code, Insurance Code, Firearm Owners Identification Card Act, Probate Act, and others) to reference the new Mental Health and Developmental Disabilities Code definitions rather than prior statutory language.

• Maintains a carve-out preserving the separate "developmental disability" definition in the Firearm Owners Identification Card Act for mandatory reporting purposes under that Act.

• Establishes consistent terminology for developmental and intellectual disabilities across state agencies while clarifying that related conditions (cerebral palsy, epilepsy, autism) are evaluated under similar functional limitation standards.
