Looks like it gets worse: After demanding that Vanig's office send me test results, I compared them to what he billed my insurance. Turns out, he's been billing my insurance for medical tests that were never conducted, and his office was forced to refund money to my insurance company. Thus, based on my experience this medical practice is pure sleaze. The problem is that Vanig's office is one of the few that will prescribe PREP. I really think Gilead needs to work with the medical community of the Phoenix area to get more doc's in the program.
