In 1965, Titles XVIII and XIX of the Social Security Act were passed, creating Medicare and Medicaid and laying the foundation for US healthcare policy. Medicare was originally created to meet the specific medical needs of adults age 65 and older. Currently, individuals with end-stage renal disease, amyotrophic lateral sclerosis (ALS), and other disabilities may also receive Medicare, regardless of age. Medicaid was established to provide a basic level of medical care to specific categories of people who are poor, including pregnant women, children, and the aged. As part of the Affordable Care Act (ACA), states are provided with the opportunity to expand Medicaid to close the coverage gap for public health insurance. This entry provides explanations of Medicaid and Medicare and associated social healthcare programs in the United States. An overview of significant programming developments and current issues of legislative consideration are also provided.
