Price and quality are not strongly correlated because the variance is just enormous: https://www.washingtonpost.com/news/wonk/wp/2015/01/21/a-knee-replacement-surgery-could-cost-17k-or-61k-and-thats-in-the-same-city/ https://www.washingtonpost.com/news/wonk/wp/2015/01/21/a-kne... > The report, which analyzed three years of BCBSA companies' claims data in 64 markets, found that the average price for a knee replacement surgery is $31,124.
