New Hustle at the Dr.'s Office?

Recently, I had a biopsy, possible cancer. When the procedure was finished, they scheduled me for a follow up appointment. I asked them, if I'm clear, why do I have to come back--can't they tell me over the phone? They said no, it's part of the procedure. I went back today. A nurse practitioner saw me, and went over the results-no cancer. I asked again, why did I have to drive 40 miles round trip to see a dr.to tell me, I have no cancer(or any other problem). Then she explained that although they took 16 different tissue samples, it is possible they missed something. So I asked: "am I cancer free, or is it I'm cancer free-more or less? At that point I got up and walked out of the office, and she followed me out, even through the waiting room, asking me if I had more questions. When I got home, there was a message from the Dr. himself, explaining to me exactly the same stuff the nurse did. What happened to the "we can't tell you over the phone" crap? Do you folks think I should pay the bill, or tell them to stick it up their asses? I thought the biopsy was to find out if I had cancer. It looks like the biopsy is to tell the Dr., and the extra hundred bucks(office call)is for him to tell me the results. Go figure
