I find it curious that people are celebrating when they manage to not pay (part of) an absurdly wrong bill that can only be either the result of gross incompetence or- much more probably- an attempt at fraud. The actual happy ending of such a story would be that the healthcare provider is sued for damages and/ or attempted fraud, and has to pay back a large multiple of what has asked.
