H.R. 7158 would authorize the Department of Veterans Affairs (VA) to pay for up to 900 veterans with severe service-connected disabilities to live in medical foster homes. Currently, VA inspects, approves, and provides home-based and case management health care to veterans living in those homes while veterans pay for their room and board expenses. Under the bill, VA would pay for those living expenses. Some of the veterans receiving this benefit would have exposures to environmental hazards, thus CBO expects that some of the costs of implementing the bill would be paid from the Toxic Exposures Fund, a mandatory appropriation. Additionally, subsection (d) would temporarily increase the fees that VA charges borrowers for home loan guarantees in 2031.
