Medicare and Medicaid were established in the United States in 1965 through amendments to the Social Security Act. President Truman first called for a national health insurance program in 1945 to provide medical coverage for the elderly and low-income populations. After years of debate, President Johnson signed legislation in 1965 to create Medicare which provides health insurance for Americans aged 65 and older, as well as younger people with disabilities. Medicaid was also established to provide medical assistance for certain low-income individuals.
