The Health Care Cost Institute is a research nonprofit funded by the insurance industry. They have a lot of data, and some of it is available in various forms for certain uses.
In this case, it’s a national comparison of hotspots for prices. “Health care prices have grown rapidly across the United States. But focusing on the national picture doesn’t capture how these rising prices have affected local areas differently. Over the last five years, price levels and growth rates varied widely for different types of health care services both across and within metro areas. In short, each locality had a different experience.
“Analyzing over 1.78 billion commercial claims, we compared the average prices paid for the same set of health care services in 112 metro areas across the country. This report presents the price level benchmarks for the U.S. health care system from 2012 to 2016 using a variety of interactive maps and charts to help consumers and stakeholders understand how the prices in their local area compare to others around the country.”
