It really bothers me that none of these stories seem to describe what legal theories are used to enforce these fabricated "debts" against the victims. It would seem there must be a whole collection of state laws that enable these practices, and I would think they would be a prime area of reform - if they were eliminated, providers would have to publish prices and form an actual contract (including a lack of duress and well-defined consideration), instead of being able to play this game of "nobody can tell you how much anything costs until the billing extorts you".
They can't put a lien on property without a court case and I want to see someone stand in front of a judge and justify an un-itemized 100k bill when their own public charge sheet shows that the service should cost <1000.
So the real disruption would be to DoS their lawyers by patients disputing absolutely everything questionable. Create an app to upload all the EOBs and make it dead simple to create grief for the hospital.
