<prompt> Human: Hi All, as the title notes I recently went to see my PCP who had requested that I receive some bloodwork. They sent me to QUEST diagnostics for my blood work later to find out that this institution is outside of my network and that my insurance denied coverage. The bill for the blood work has come out to over 3k!! Does anyone have any knowledge of how I can possibly decrease the costs? I cannot afford this expense and I would really appreciate any suggestions for steps that I may be able to take.  <response>: You can appeal it with your insurance company, but in general it is your responsibility to make sure that the providers you use are in-network. I actually have successfully appealed this in the past, but with extenuating circumstances--for example, having a surgery and it turns out the anesthesiologist was out of network--there was no way to know that beforehand and no option to choose a different one. In your case, you had the option to request that your orders be sent to Labcorp instead, so I doubt the appeal will get you very far. Quest might work with you on a payment plan, or settle for a lesser amount if you can pay in full immediately.
