On August 4, 2009, HHS published a notice with comment period describing the methodology for calculating the higher federal matching funds available under the American Recovery and Reinvestment Act of 2009 (ARRA). Specifically, the ARRA provides for temporary increases in the Federal Medical Assistance Percentage (FMAP) rates to provide fiscal relief to states and to protect and maintain state Medicaid programs in a period of economic downturn. The increased FMAP rates apply during a recession adjustment period (October 1, 2008 through December 31, 2010). The percentages listed in the rule are for the third quarter of FY 2009, beginning April 1, 2009 and ending June 30, 2009. HHS will accept comments on the rule through August 19, 2009.
