Created in 1965, Medicare is a public healthcare program for people over 65, as well as those enrolled in Disability Insurance and those with end-stage renal disease. Medicare began with two areas of coverage - hospital insurance (Medicare Part A) and medical insurance (Medicare Part B). In the 1980s, Medicare Part C, also known as Medicare Advantage, was added as an alternative to traditional Medicare. In 2006, outpatient prescription drug coverage was added under Medicare Part D.
In recent years, as the elderly population has increased, Medicare participation has grown to 18% of the population. However, for those not enrolled in the program, some aspects may be surprising.
