On Wednesday, the U.S. Government Accountability Office reported Dallas has some of the most expensive hospitals in the country. GOA reported some hospitals in the Dallas-Fort Worth-Arlington metropolitan area  charging above-average for heart artery stents, total hip replacements and appendectomies.

GAO found that more than 90 percent of the difference in spending across the country for the above three surgeries was due to hospital charges and the difference in charges vary by upto three times in the case of total hip replacements.

Government Accountability Office (GAO) is  an independent arm of the federal government
