Can a doctor charge for two office visits at one appointment and make you pay 2 copays?

On the face of it, this does not sound correct. Sure they can bill you, doesn't mean that they will get paid. I would ask for an itemized bill for the (2) charges and an explanation in writing. Also let your insurance carrier know of what occurred. The doctors will more likely pay attention to the carrier as that is where the real money is coming from. Example: I went to my doctor for a cough. He checked my ears and told me that I needed to come again to get extra wax out of my ears. I did not understand why he would not do it in the first visit. He would not have been paid for getting the wax out if he had done it on my first visit. Not to mention, I stopped seeing the doctor. Making money is good but doing it at the expense of one's health is immoral. Generally, they will bill seperately for the office visit and bill also for the doctor diagnosis. I was billed a few times like this when my wife was getting ultrasounds at a hospital. Once for the reading and once for the visit.
