<prompt> Human: Hi, any help is appreciated. My wife has a thyroid issue. Our doctor prescribed labwork to test her blood, but when we asked how much it would cost, he had no idea. We are insured by Blue Cross Blue Shield. I went to their online estimate your cost tool Castlight, and it said about 50-100. So we went to get the labwork done at Quest Diagnostics, one of the clinics in the network. I had checked and labwork is probably not covered we have the very basic plan with huge deductibles, but at 100 out of pocket I didnt worry too much. At Quest, as I handed over the prescription, I asked the workers there about how much this would cost, but of course I get no idea, and insurance will cover it even though I specifically told her that it probably will not.I still have not received a bill, but I check my claims online daily. Today, I saw that the claim was denied by BCBS, which I expected as this is probably not covered. However, I was dumbfounded to find the bill to be over 700 - for routine thyroid checkup. Being always the proactive person I am, I will call Quest Diagnostic first thing in the morning, though I am 90 sure they will say to wait for a bill. Screw that. I will also need to call the doctor, but Im sure he will say this is out of his hands. Insurance company? Forget about it they will say its clearly not covered. Even someone as careful as myself gets screwed by this. This is absolutely ridiculous. The question is - what can I do about it? Please dont say just wait for things to sort out - if there is anything Ive learned on my short time on earth, its that it doesnt.Thanks for any suggestions.  <response>: The 700 is almost certainly the list price which nobody pays. Once you get the bill it will be at the insurance negotiated rate. Even though they dont cover it you still get their discount.I went in for a sprain and first bill to insurance was almost 1000. When I got my bill it was about 300.
