Billed hospital charges per item?

I have a dilemma. I have a limited benefits insurance company that I am going to use for sleeve WLS. It has caps on the amounts it will pay for certain hospital charges, etc. Going round and round with the insurance company and hospital has pretty much gotten me nowhere since no one wants to commit to an amount. I can understand that, but I also need to know what I might possibly be looking at in terms of what this is going to cost me out of pocket.

If anyone has an itemized bill for their surgery and would be willing to share the information with me, I would really appreciate it. I know how much the surgeon will cost; it is the hospital charges I need to know. For example, how much it cost for the operating and recovery rooms, meds, medical and surgical supplies and devices, lab tests and x-rays, etc.

I know that your amounts won't be exactly the same for me, but at least it might give me an idea of what to expect. The surgeon requires a two-day hospital stay. What I especially need to know is what the hospital billed the insurance company - not self-pay. I have Aetna and this is a preferred provider, but the policy isn't a traditional Aetna policy because of the caps (I also do not need nor will they do preauthorization). So, while I'm assuming that there are allowed amounts, I have no idea what those are.

Any help would be greatly appreciated!

Thanks.
