Anyone work for a hospital or their billing department? Private or public...

Anyway, I went to a private hospital (nearest one) and my bill was approx. $10,000. Since we paid a % cash before we left they said they would knock-down the bill 40-60% well we got 50% off the total bill.

I`m wondering if I can negotiate this even further. Either by removing an item from the bill or simply asking for the other 10% off.

What upsets me the most is my CT Scan, they did 2 because the guy wasn't sure the first one went through... and if you've gotten a CT Scan you know that to take a second took an additional 30 seconds and I was charged nearly the full amount again (3311 not 3487) to take the darn second image. *GRR**

So, anyone have any tips or suggestions for negotiating this down some more?

Thanks!
