The 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 these services, which include mental health and substance use treatment. Key provisions of the act include a new federal matching rate of 90 percent for any increased state expenditures on behavioral health services. This applies to the amount spent that exceeds what was spent during a specific period in 2019.
