America's seniors ought to wish Medicare a happy 50th birthday. Continued improvements to the federal healthcare insurance program cut the Medicare patient mortality rate 16 percent -- the equivalent of 300,000 deaths per year -- from 1999 to 2013.
A large part of the decreased mortality is due to Medicare "Part D," which offers prescription drug coverage to 37 million seniors. In an effort to cut costs, some lawmakers want to retire the model that has enabled Part D to achieve a 90 percent satisfaction rating and come in $350 billion under budget.
