Adds Down syndrome to the definition of developmental disability and expands such definition to include certain individuals below the age of ten

This bill amends New York's mental hygiene law to automatically include Down syndrome as a qualifying condition under the definition of developmental disability for Medicaid eligibility. It adds Down syndrome to a list of specific conditions (alongside cerebral palsy, autism, and others) that now qualify individuals for Medicaid without needing separate assessments. People with Down syndrome who meet income and other standard Medicaid criteria will automatically qualify under this change. The law takes effect immediately upon enactment.
