The 2010 health law was meant to expand insurance coverage so that Americans could get medical care they would otherwise go without — and not spend a fortune doing so. Though it’s still early, new evidence suggests this scenario is playing out.

Medicare spending on prescriptions increased more than 17% in 2014, despite a claims increase of only about 3%, according to data released Thursday.

The “most important factor” that drives prescription drug prices higher in the United States than anywhere else in the world is the existence of government-protected “monopoly” rights for drug manufacturers, researchers at Harvard Medical School report today.
