I also tried to ask "how much?" on my last doctor's visit. I was looking for a ballpark estimate, not an exact figure. The person at the desk refused to give me one, citing that insurance plans make that too difficult. I insisted that since I was covered by a major insurer that she must surely deal with regularly given their customer base, and that their office was in-network for my plan, she must have
some idea, but again, she refused, saying she didn't know.
It's ridiculous, and it should be illegal. At the time, my reason for visiting was a condition that required treatment, so not going to the doctors really wasn't an option. But the inability to even begin to determine what I'm going to pay is ridiculous.
(I did this after a prior visit to a different doctor stiff'd me something like $3k for the use of what amounts to glorified camera. A camera whose photos I never obtained, despite asking for them — to which the doctor replied "we've never had anyone ever ask for that" — i.e., for their medical records. I could understand that medical-grade cameras might not be cheap, but at $3k per use, my gut says money is raining from the sky.)
