Although Dr. Nieto was nice but him or someone else is ultimately responsible to make sure procedures are followed. I called and gave them my insurance information and they said they were in my network even the day of my first visit I asked them, so I had an order for MRI and went back for my second visit today , the receptionist wanted me sign a paper to acknowledge that Dr. Nieto is out of my network, I said but you told me he was on my first visit, she started telling me yes we thought he was but it was a mistake and tried to convince me to sign and see the doctor , I said no and left because they wasted my time by not giving me the right information and now they want me to pay the extra, not sure if they did this intentionally to just get me in there or it was a mistake but regardless they didn't do their job right.
