This legislation, known as the Mental Health Infrastructure Improvement Act of 2025, empowers the Secretary of Health and Human Services to offer loans and loan guarantees for the development and enhancement of mental health and substance use disorder treatment facilities. These financial mechanisms can be used for planning, constructing, or renovating facilities that serve both pediatric and adult populations. Additionally, funds can support improvements to digital infrastructure, telehealth capabilities, and the addition or conversion of inpatient psychiatric and substance use disorder beds.

The bill prioritizes projects that will increase bed capacity in areas with insufficient resources, provide services in high-need rural or underresourced communities, and offer a comprehensive continuum of care. Preference is also given to facilities capable of providing integrated or specialized care for complex cases. A significant provision mandates that at least 25 percent of the allocated funds each fiscal year must be directed towards facilities primarily serving pediatric and adolescent populations.

Loans and loan guarantees come with specific terms and conditions, including a requirement for borrowers to finance at least 25 percent of the project from other sources and for interest rates to be set with reference to Treasury securities. The Secretary must assess credit risk and ensure reasonable repayment, with the government covering 75 percent of losses on guaranteed loans in case of default. The overall funding authorization for these loans and guarantees is set at $200,000,000 annually for fiscal years 2026 through 2030, subject to appropriations.

Finally, the bill establishes the Mental Health and Substance Use Treatment Trust Fund in the Treasury. This fund will receive revenues from the loan and loan guarantee program that exceed its operational costs. Amounts within this Trust Fund will then be available, through appropriation acts, to support block grants for community mental health services, further strengthening the nation's mental health infrastructure.
