The Fatal Overdose Reduction Act of 2025 aims to enhance access to treatment for individuals suffering from opioid use disorder and other substance use disorders by establishing the Health Engagement Hub Demonstration Program under Medicaid. This program will create designated centers, known as Health Engagement Hubs, that provide comprehensive support and treatment for those affected by substance use issues. The legislation outlines key provisions for these hubs, which must meet specific criteria to be certified by states.
