\*EDIT: I've been corrected by a few people-- The person I was interacting with was probably a medical technician/phlebotomist, not a nurse. Sorry for the mix-up in the title. Hi all. I have a problem, and I'm not sure what to do. Earlier this week I (24F) went to a Labcorp office to get blood tests done in advance of my hematology appointment (this is something I have to do multiple times a year). When I got there and was checked in, the medical technician\* asked me if I was there on the orders of "Doctor Smith" (fake name). I told her that while Doctor Smith was one of my doctors, I was actually there at the request of my hematologist, "Doctor Johnson." The Labcorp worker told me that there was nothing from Doctor Johnson's office in the system, and the request from Doctor Smith was the only one she could see, so it HAD to be the right one. Since she was the expert, I assumed she was right and went along with it. Well, that was a bad move. Instead of giving me the tests I needed, the medical technician\* redid ten completely unrelated tests that I had already gotten done in August. Now I found out that they're planning to charge me $220 for the incorrect tests, plus I need to go back and have more blood drawn because I still haven't done any of the tests I need for my hematology appointment. Is there anything I can do to not pay this initial $220 bill? It really feels unfair to me, mostly because I already had to pay an identical bill back in August when I got these tests done the first time. I've already called the Labcorp, my insurance, and the hematologist's office, but all of them seem really unsure about the situation. Which one should I keep calling? For extra context... I live in Maryland and make roughly $65k a year. I'm on my dad's insurance.
