Coronavirus Medicaid Response Act This bill increases the Medicaid federal matching rate, also known as the Federal Medical Assistance Percentage (FMAP), for states and U.S. territories that experience economic downturns (i.e., high unemployment) beginning on or after January 1, 2020, in accordance with specified requirements and limitations. The bill's increase is in addition to previously enacted FMAP increases relating to COVID-19 (i.e., coronavirus disease 2019) but may not result in an FMAP greater than 95%.
