Since Medicaid's creation in 1965, it's become the largest health insurer in the country, covering more than 70 million Americans. Initially covering only poor, single parents and their children, the program now also offers government-subsidized insurance to disabled people, able-bodied adults without kids and some elderly.
The program's expansion may slow down a bit, but it’s not likely to stop anytime soon, and there’s a whole lot of reform going on, along with major shifts in coverage.
