Chicago filmmaker sheds light on hospital billing practices

So what is this about?

The film tells the story of two Albany, Ga., men, physician John Bagnato and accountant Charles Rehberg, who in 2003 blew the whistle on their local hospital, Phoebe Putney. They accused the hospital of overcharging poor people, forcing many into bankruptcy.

The hospital denies those claims.

But, Schanberg, 37, says is that the practice is widespread - especially in Illinois.

"I thought the doctors knew about what happened once their patients walked out the door, but they have no idea," says Schanberg, a Chicago resident who also calls New York home.

The next question is how did these two gentlemen found themselves in Illinois and found this phenomenon?
