> Call the office back and ask why you’re charged as medical?

I did that when I originally got the bill in the mail, because I was very confused. And they said the procedure I got was a medical exam, so the billing was correct. I don't recall the exact words, but they told me I should have asked for the regular exam.

It seems to me that the person behind the counter should have been a lot more careful to make sure they understood why I was there and what kind of appointment they were setting for me. I had no idea there were two kinds of eye exams, and I've been wearing glasses my whole life.
