Probably the reason the person answering the phone can't answer your question about how much your appointment would cost is this.

It depends on the depth of the appointment and the procedure code the doctor uses for the visit. Then it would depend on whether the doctor does any procedure like freezing off any lesions, and how many lesions. There are different procedure codes for the number of lesions they might treat. Maybe they biopsy something too, that would be a different procedure code.

So they might have told you what an initial visit costs, but even that would just be a starting point.
