The main purpose of this legislation, known as the Medicaid Bump Act, is to enhance funding for behavioral health services under Medicaid. It aims to provide a higher federal matching rate for states that increase their spending on mental health and substance use services. This is intended to improve access to and the quality of behavioral health care for individuals who rely on Medicaid. Key provisions of the legislation include a new federal matching rate of 90 percent for any additional state spending on behavioral health services that exceeds a baseline amount from 2019.
