This bill establishes a federal grant program within the Department of Health and Human Services to help coordinate healthcare and homelessness services for people experiencing homelessness who have behavioral health issues like mental illness or substance use disorder. The program would award competitive grants of up to $500,000 each for five years to eligible entities including government agencies, nonprofit organizations, public housing authorities, and tribal organizations that are designated by local continuums of care. Grant funds can only be used to build coordination capacity, such as hiring system coordinators, improving technology infrastructure, and enhancing connections between health and homelessness service providers, but cannot be used to directly pay for healthcare or rent. The bill authorizes $20 million annually from fiscal year 2023 through 2028, with at least five percent reserved for tribal entities, and requires grantees to report annually on outcomes such as whether clients were housed, enrolled in treatment, and had improved health outcomes.
