Medicare covers the elderly population (65+ years old) regardless of income or health status and represents the country’s only version of national health insurance. The program was expanded twice: (1) in 1972 to include individuals under 65 suffering from end-stage renal disease (ESRD) and the disabled who received Social Security Disability Insurance (SSDI) payments, and (2) in 2001 to cover people with amyotrophic lateral sclerosis (ALS, or Lou Gehrig’s disease).
