This chapter addresses the issue of health care for low-income people. The United States, virtually alone among developed nations, does not offer universal access to health care, leaving many millions of individuals without health insurance or other means of obtaining necessary medical services. In 2010, Congress enacted the landmark Patient Protection and Affordable Care Act (ACA)—popularly known as “Obamacare”—marking an important but incomplete response to the nation’s health care crisis. This chapter examines the ACA in detail, including its impact on Medicaid and Medicare, the major government health programs in the United States, its creation of Health Insurance Exchanges and tax credits to help low-income households obtain private health coverage, and the reform of private health insurance markets through a patient’s bill of rights, which, among other measures, prohibits insurance companies from refusing coverage for preexisting medical conditions. Perhaps the most critical aspect of the ACA was its expansion of Medicaid to cover virtually all low-income citizens (and certain immigrants) who do not qualify for other health coverage. Although several states opted out of the ACA’s Medicaid expansion, the Medicaid program nevertheless remains the largest single provider of health coverage in the United States. This chapter also provides a detailed description of Medicaid, its eligibility criteria and scope of coverage; the Child Health Insurance Program (CHIP), a government-funded health insurance program for children in households with too much income to qualify for Medicaid; and Medicare, the federal health insurance program for aged, blind, and disabled individuals.
