SSI Disabled and Blind Children Act of 1989

SSI Disabled and Blind Children Act of 1989 - Amends title XVI (Supplemental Security Income) (SSI) of the Social Security Act to require the Secretary of Health and Human Services to conduct an individualized assessment of a child's mental and physical impairments in determining his or her eligibility for SSI benefits by reason of disability or blindness. Establishes a presumption that a child under age four with a genetic or congenital impairment is disabled or blind for SSI purposes if it is probable that more accurate clinical and laboratory techniques would prove such to be the case. Directs the Secretary to publish, within 30 days of this Act's enactment, a revision of specified listings of mental and emotional disorders which justifies each deviation from recommendations contained in the Revised Childhood Listings of Mental Impairments submitted by the Mental Impairment Listings Workgroup to the Associate Commissioner for Disability on April 1, 1986. Requires the Secretary to: (1) consider age-appropriate medical and functional criteria developed by experts in childhood disability in reviewing and revising all childhood listings; and (2) publish a revised listings and explain deviations from the recommendations of experts within 18 months of this Act's enactment. Establishes a formula for determining the amount of parental resources deemed available to a disabled or blind child for SSI benefit and eligibility purposes. Excludes property which is essential to the self-support of an individual from his or her resources, but includes income from such property in such individuals earned income. Requires States to provide Medicaid coverage (under title XIX of the Act) for all SSI blind or disabled children.
