The Medicare Initiative is a federal program established in 1965 as part of the Great Society reforms, providing health insurance to individuals aged 65 and older, as well as younger individuals with disabilities or specific diseases. This initiative aimed to ensure that elderly citizens had access to necessary medical care, addressing the growing concern over healthcare accessibility for seniors in America during the mid-20th century. The initiative has since expanded and evolved to include various plans and services, reflecting changes in healthcare needs over the decades.
