The Medicare Act is a federal law enacted in 1965 that established the Medicare program, providing health insurance to individuals aged 65 and older, as well as some younger people with disabilities. It aims to help cover the costs of hospital stays, medical services, and prescription drugs, ensuring that seniors have access to necessary healthcare. The act has undergone several amendments over the years, expanding coverage options and services. Key components include Part A (hospital insurance) and Part B (medical insurance), with the introduction of Part D in 2003 to cover prescription medications. The Medicare Act plays a crucial role in supporting the health and well-being of millions of Americans.
