Medicaid home- and community-based services; modifying certain definition. Effective date.
SB 1555 updates Oklahoma's Medicaid definitions for "individual with intellectual disability" and "developmental disability" to align with current standards. It raises the age for disability manifestation from 18 to 22 years, refines IQ criteria (e.g., requiring scores below 70 or 71-75 with specific scoring), and revises adaptive skill areas to match Social Security Administration guidelines for daily living skills. These changes directly affect Medicaid eligibility for individuals seeking home- and community-based services under Oklahoma Statutes §1406-1424. The bill ensures existing Medicaid recipients as of September 1, 1991, remain eligible, and the Department of Human Services may expand services for underserved individuals within available resources. The updated definitions take effect November 1, 2026.
