Creates a temporary enhanced federal Medicaid match that pays 90% of the amount by which a State’s quarterly Medicaid spending on behavioral health services (mental health and substance use) exceeds the State’s spending in the comparable quarter of the 4-quarter period ending March 31, 2019. States must use the extra federal funds to add to, not replace, their own funds and to improve service delivery (for example, raise provider payment rates and reduce staff turnover). The Health and Human Services Secretary must issue guidance within 180 days defining which services count as behavioral health. The match applies to calendar quarters starting Jan. 1 of the year that begins one year after enactment.

Requires the HHS Secretary to send Congress an annual report (first due within one year of enactment) on Medicaid behavioral health services in each State that lists payment rates, explains how rates were set, and includes utilization data where available.
