Bingo. My partner works in revenue cycle management (arguing with insurance companies to pay their bills) for a large hospital chain, and even she can't get accurate prices for procedures. She can walk down the hall to the finance department, and ask them, but even they can't figure it out.

I found this out after asking her why they don't prioritize cases with the largest bills, and she said it's because the billed price of the procedure has no relation to the actual priced paid. They could review a $800,000 cancer case and only recover $750.
