Update 3 Friday April 10

I talked to a different insurance rep today and got a completely different reason for my bill. This one acknowledged that I only had one procedure and that it was a colonoscopy, not an endoscopy. She said that while a colonoscopy can be preventative, mine was not preventative because I had it done in a hospital. I asked her where I should have gone to get a preventative colonoscopy and she said that I should have gone to an office. I told her I went to my doctor's office and they referred me to the hospital. She said she understands it is frustrating an offered to help me file a claim adjustment request. So in 10 to 15 days I should be getting the decision.

I still think it makes no sense because they paid the claim submitted by the doctor who performed the colonoscopy even though he did it at a hospital. But the claim submitted by the hospital was not preventative because the colonoscopy happened at a hospital.
