Proposing a constitutional amendment requiring the state to expand eligibility for Medicaid to certain individuals under the federal Patient Protection and Affordable Care Act.

HJR 100 proposes a constitutional amendment requiring Texas to expand Medicaid eligibility to all individuals who qualify under the federal Affordable Care Act (ACA) and for whom federal matching funds are available. It would directly affect low-income Texans who currently fall into the Medicaid coverage gap but meet federal ACA eligibility criteria. The amendment mandates that the state provide medical assistance to all such applicants when federal funds are accessible, without imposing new state costs. If approved by voters in November 2025, the change would take effect January 1, 2026, and expire January 1, 2027, unless ratified by voters.
