What is the federal medical insurance program established in 1965 under Title XVIII of the Social Security Act?

The federal medical insurance program established in 1965 under Title XVIII of the Social Security Act is Medicare. Originally designed to provide health coverage for individuals aged 65 and older, Medicare has since expanded to include certain younger individuals with disabilities and those with specific health conditions, such as End-Stage Renal Disease or Amyotrophic Lateral Sclerosis (ALS). Medicare is composed of different parts that cover services like hospital stays, outpatient care, and prescription drugs. This program plays a crucial role in providing health insurance to millions of Americans, significantly influencing healthcare access for the elderly and vulnerable populations. Other programs mentioned, such as Medicaid, provide different types of assistance and have different eligibility criteria, which distinguishes them from Medicare.
