<prompt> Human: I went to this doctor back in November 2015 as I wasnt feeling well and wanted to do some blood work to make sure everything looked okay. Fast forward to May 2016 and I get a bill from a lab for 522. I call the doctors office and they tell me its not their problem and I need to call the lab. The lab asks for my insurance information. Once I provide it to them, they tell me that the doctors office provided them with different insurance information so thats why it was rejected. The doctors office was disorganized and I wasnt impressed with them so this honestly didnt come as a surprise to me. The lab said theyd update my bill as pending insurance and it should all be good to go. Great!August 2016 I get another bill from the lab for 522. Why? I call the lab back and they say the insurance company isnt responding. She looks over my insurance information and then tells me theyre likely not responding because they work with a different lab and they dont cover their lab work. Awesome, so I ask again just to be sure that this claim is being ignored because they dont cover your lab and she repeats yes. Terrific, Im now on the hook for a 500 bill because my doctors office didnt look to see what lab my insurance works with. I specifically called my insurance company prior to going to this doctor to make sure they were covered and was told they did. The doctors office confirmed it. I never paid more than a copay for any visit before.I call the doctors office and tell them I need to speak to someone cause they sent my blood work to a lab that my insurance didnt cover and Im stuck with a 500 bill. I could tell in her voice she wanted nothing to do with my call. She puts me on hold for 15 minutes IMO to encourage me to hang up. I stayed on the line. She gets back on and tells me that I need to speak to the lab. I inform her I did already and that the lab isnt responsible for sending my blood work to them when it wasnt covered. She then tells me its my fault because I shouldve known where my blood work was going. WHAT?! I ask her for documentation stating what lab my blood work was going to. She couldnt provide it. I give her a spiel about how their error is now costing me 522 and I dont think thats right. She finally agrees with me, but then tells me that theres nothing they can do about it. I let her know an apology would be a terrific start and then a follow up call with management is needed because we need to come to some sort of resolution. This isnt acceptable.Has anyone had an experience like this? Who do I report it to? I plan on doing some research on my own but I was curious if there were similar experiences out there. Thanks for your help.TL;DR - Doctors office sent blood work to a lab that my insurance didnt cover, insurance wont cover it, lab needs a payment or itll eventually go to collections, doctors office says there is nothing they can do about it. What action do I take against the doctors office, if any?Edit: Based on the feedback Im getting, which I very much appreciate, Im wrong on the doctors office being at fault. I still cant fathom why after seeing my insurance they sent my labs to someone my insurance doesnt cover. However, Ill concede the fault. The lab has agreed to waive half the bill, so thats a plus. Insurance isnt willing to do anything. My company doesnt even use them for insurance anymore; they swapped at the beginning of 2016.Ill chalk this up as a personal LPT - find out where your labs are going before theyre sent to mitigate any future issues. Hopefully one day well have a better and simpler healthcare system in the U.S. and situations like this will be minimized for everyone. Thanks again, folks. This is what makes Reddit great. :Edit 2: Seriously folks, this is great advice. Just to clear this up, I did speak with my insurance company and theyre not willing to pay. Why are they ignoring the lab? I honestly dont know. I didnt think to ask once they flat out said that the lab was out of network and they wouldnt pay. The lab settled with me at half and I paid the half. It sucks and I still dont feel its right, but Ill be buying a house in the next couple months and having a non-payment hit my credit is simply not something Im willing to let knowingly happen regardless of whether I feel its unjustified. Ive learned a good lesson and Im more knowledgeable moving forward. Thats my best outlook on this situation.  <response>: Insurance broker here...Your best bet is to contact your states insurance superintendent, open up a claim against the Dr., the lab, your agent, and the insurance company. Once this has happened, insurance companies are way more likely to comply.
