I had to get some bloodwork done. I sent emails and made calls until I found a provider who would actually tell me the prices. Then the bill came and it was 3x higher. I wanted to know if it was the doctor's error or the lab's, so I asked for any paperwork requesting services submitted by the doctor, and they ignored me and sent it to collections, where it has been for the last 2+ years.
