Medicaid Financing and Expenditures

Medicaid is a means-tested entitlement program that finances the delivery of primary and acute medical services as well as long-term services and supports. Medicaid is a federal and state partnership that is jointly financed by both the federal government and the states. The federal government?s share for most Medicaid expenditures is called the federal medical assistance percentage (FMAP) rate. Generally determined annually, the FMAP formula is designed so that the federal government pays a larger portion of Medicaid costs in states with lower per capita incomes relative to the national average (and vice versa for states with higher per capita incomes). Federal Medicaid funding to states is open-ended. The federal government provides states a good deal of flexibility in determining the composition of the state share (also referred to as the non-federal share) of Medicaid expenditures. As a result, there is significant variation from state to state in the funding sources used to finance the state share of Medicaid expenditures. In state fiscal year 2010, states reported that on average state general funds (i.e., revenues from personal income, sales, and corporate income taxes) made up 76% of the state share of Medicaid expenditures and the remaining 24% was financed by ?other state funds? (i.e., provider taxes, local government funds, and tobacco settlement funds). In FY2011, Medicaid expenditures totaled $428 billion, with the federal government paying $271 billion, about 63% of the total. While Medicaid expenditures (like all health expenditures) generally grow at a rate faster than the economy, as measured by the gross domestic product (GDP), spending per enrollee under Medicaid tends to be lower than the per person spending for other forms of health insurance. One of the major factors impacting Medicaid spending is the economy. Also, state-specific factors, such as programmatic decisions and demographics, affect Medicaid expenditures and cause Medicaid spending to vary widely from state to state. Starting in FY2014, Medicaid expenditures are expected to increase significantly as a result of the reforms enacted in the Patient Protection and Affordable Care Act (ACA, P. L. 111-148 as amended). The most noteworthy ACA change to Medicaid begins in 2014, or sooner at state option, when some states expand Medicaid eligibility to adults under age 65 with income up to 133% of the federal poverty level (FPL) (effectively 138% FPL with the Modified Adjusted Gross Income 5% FPL income disregard). Following the June 28, 2012, Supreme Court decision in National Federation of Independent Business v. Sebelius, it is uncertain how many states will refuse to expand their Medicaid program to cover this new group. The Congressional Budget Office and the Joint Committee on Taxation updated their estimate of the ACA Medicaid expansion to account for the Supreme Court decision, and they project the expansion will cost $642 billion from FY2014 to FY2022, which is $288 billion less than the estimate prior to the Supreme Court decision. This report provides an overview of Medicaid?s financing structure, including both federal and state financing issues. The Medicaid expenditures section of the report discusses economic factors affecting Medicaid, state variability in spending, and projected program spending. Other issues that are examined include congressional proposals to turn Medicaid into a block grant program, federal deficit reduction proposals affecting Medicaid, and state fiscal conditions affecting Medicaid financing and services.
