My girlfriend fell skiing and tore her ACL. We were taken down to the mountainside clinic. They were just gonna do a basic check and give her some Advil and a brace. I asked how much it would cost. They said they were not ALLOWED to tell me. Which is different than not knowing. I told them what insurance I had. They said many people came in with that insurance. I asked how much of the procedure is normally covered. Also apparently a secret. I just can't see how it's legal to bill someone for services received while refusing to give information on what it will cost. If the bill had been $50k what recourse would I have had?
