We’re all so used to seeing insanely high medical bills that most of us don’t even question the numbers. But what if you had the time and expertise to actually challenge each service and product itemized on your bill? Sunita Kalsariya decided it was worth effort to challenge the $7,922.62 bill her husband got after going to the ER with a broken arm—then getting charged an arm and a leg. “Kalsariya had no way of knowing then that she was embarking on a crusade that would take over a year, send their bill to debt collections, lead her to complain to the Illinois attorney general, and discover that the hospital charged nearly $7,000 for a procedure that was never performed.” NBC: A billing expert investigated her husband’s ER bill. She was able to knock thousands off the charge.
