Frustrated with Bailey's billing dept

I initially received a bill from Bailey saying that I owed them 611.12.  I talked to their billing department and told them that I hadn't received a statement yet from my insurance company showing what my part was.  I called my insurance company and they said that I didn't owe anything because of "negotiated rates".  In the week it took from when Bailey called me and I got the paperwork from my insurance company Bailey had sent it to a collection company.  I faxed all of the paperwork from insurance to the collection company that showed for the date of service I owed nothing, got a confirmation that the fax went through and never heard anything else.  I get home from work last night and received a letter from a law firm for the 611.12.  I have no idea what these charges are that Bailey is trying to collect on, sure I know it has to do with my surgery, but I don't know specifically what isn't covered.  I called the law firm and of course they were closed.  I called Bailey and they no longer have my information in their system so I have to call Hillcrest today.  Am I out of line thinking that I should be getting some kind of itimized bill for what they are trying to collect on?  If I really owe the money I'd have no problem paying them but I am not sure that I owe it to them since my insurance has paperwork showing that I don't!  I think I'm going to be on the phone quite a bit today.  Has anybody else had this problem with Bailey, and if so, how was the resolution?

It can be a pain, but if you fax proof from your insurance to the collection office that you owe nothing for that stay, they will have to stop bugging you and send it back to Bailey to write off.  Luckily, I got my issue with them straightened out before it went to outside collections.

Anymore, most of the hospitals I have been in here, only bill you for 90 days following services before they turn it over.  No patience on their part and someone is always making mistakes and not making the proper adjustments to the billed vs contract fees.
