Medicaid: The Federal Medical Assistance Percentage (FMAP)

Chris L. Peterson

Medicaid is a health insurance program jointly funded by the federal government and the states. Generally, eligibility for Medicaid is limited to low-income children, pregnant women, parents of dependent children, the elderly, and people with disabilities. The federal government's share of a state's expenditures for most Medicaid services is called the federal medical assistance percentage (FMAP). The remainder is referred to as the nonfederal share, or state share. 

Generally determined annually, the FMAP is designed so that the federal government pays a larger portion of Medicaid costs in states with lower per capita income relative to the national average (and vice versa for states with higher per capita incomes). For FY2010, the regular FMAPs—that is, excluding the impact of the temporary FMAP increase included in the American Recovery and Reinvestment Act of 2009 (ARRA, P.L. 111-5)—range from 50.00% to 75.67%. In the State Children's Health Insurance Program (CHIP), expenditures are generally reimbursed at the enhanced FMAP (E-FMAP). This is calculated by reducing the state share under the regular FMAP by 30%. 

In recent years, the fiscal situation of the states has focused attention on Medicaid expenditures, as well as on changes in the federal share, or FMAP. In the 108th Congress, the Jobs and Growth Tax Relief Reconciliation Act of 2003 (P.L. 108-27) provided temporary fiscal relief for states and local governments through a combination of FMAP increases and direct grants. In the 109th Congress, provisions to exclude certain Hurricane Katrina evacuees and their incomes from FMAP calculations and to prevent Alaska's FY2006-FY2007 FMAPs from decreasing were included in the Deficit Reduction Act of 2005 (P.L. 109-171). In the 110th Congress, a temporary FMAP increase was included in economic stimulus legislation that was debated but not adopted at the end of 2008. 

In the 111th Congress, ARRA included a temporary FMAP increase for nine quarters, subject to certain requirements. The Administration estimated that the provision will increase federal payments to states by more than $90 billion. For the first quarter of FY2010, the FMAPs reflecting the ARRA increase ranged from 61.12% (Alaska) to 84.86% (Mississippi). (The ARRA FMAP increase does not affect the CHIP E-FMAP.) The ARRA FMAPs end December 31, 2010. 

On March 10, 2010, the Senate passed H.R. 4213 (American Workers, State, and Business Relief Act of 2010), which includes a provision to extend the ARRA FMAPs by two quarters, through June 30, 2011. The House may consider the Senate-passed version or participate in a conference to resolve their bills' differences. 

The new health reform law enacted March 23, 2010 (P.L. 111-148, H.R. 3590, the Patient Protection and Affordable Care Act, or PPACA, as amended by P.L. 111-152), did not extend the ARRA FMAPs. PPACA requires that for states to get any Medicaid matching funds, they cannot make Medicaid or CHIP "eligibility standards, methodologies, or procedures" more restrictive than those in effect on March 23, 2010, PPACA's enactment date. In 2014, the law requires states with Medicaid programs to expand coverage to some currently ineligible low-income parents and childless adults. For these newly eligible individuals, states will have a 100% FMAP for three years and then slightly reduced rates well above regular FMAPs.
