I had a doctor once recommend a temporary treatment that would be provided by a third party. I called the third party and asked how much it would cost; they had no idea. I called my insurance company and asked how much it would cost; they had no idea. I called my doctor and asked how much it would cost; they had no idea.

Literally nobody involved in the entire chain of providers had any idea how much it would cost. The best advice anybody could give me was to get the treatment, then look at the bill afterwards. (Oh, and nobody had any idea when I might get a bill either-- my wife is still receiving bills from the birth of our most recent child, 18 months ago.)
