One of the key provisions of the Affordable Care Act is its "Medicaid expansion." The Medicaid program offers federal funding to states in order to assist pregnant women, children, needy families, the blind, the elderly, and the disabled in obtaining medical care. The Act expands the scope of the Medicaid program and increases the number of individuals the states must cover. For example, the Act requires state programs to provide Medicaid coverage by 2014 to adults with incomes up to 138 percent of the federal poverty level, though many states now cover adults with children only if their income is considerably lower, and don't cover childless adults at all. The Act increases federal funding to cover the states' costs in expanding Medicaid coverage. If a state doesn't comply with the Act's new coverage requirements, it might lose not only the federal funding for those requirements, but all of its federal Medicaid funds.
