There's been a lot written recently about efforts to make health-care pricing more transparent. Here's an example of one that's failed, though. I went to Seattle this month with other D.C.-based health reporters through a Kaiser Media Fellowship to examine the state of health care in Washington. The most frequent topic of discussion during the trip was Washington state's relatively successful Obamacare health insurance exchange and the challenges it still faces. A close second, though, was the defeat of legislation that would have greatly expanded health-care price transparency in the state.
