<prompt> Human: I have great credit and was dismayed to receive a collections notice from a collections agency trying to collect 170 in lab fees on behalf of Pathology Inc., which is no longer in business and whose website shows a blank page for services performed in February 2016. I disputed the debt and received documents from the agency showing that basically my former doctors office forwarded the wrong health insurance info to the lab and so of course the outdated insurance company did not pay the bill, since I was not covered under that company at the time. I never received a bill from the lab in the mail, although the collections agency sent me a copy of a bill that was dated in May 2016.Reddit, please help, what do I do? Its only 170 so I just want this to go away, so far it has not hit my credit report but Im not sure if it may just be a lag and the debt will show up in a few weeks. Theres no one I can call at Pathology Inc lab to provide corrected insurance information to because Pathology Inc is no longer in business, I guess their assets were acquired by LabCorp?What is the best course of action for me to respond to the collections agency? Thanks so much in advance for any help you can provide. Ugh!!!  <response>: My wife is a billing specialist at a pathology lab I also work there, side note: doctors offices are FUCKING USELESS about this stuff. Tell Labcorp they need to send a claim to your insurance - even though its past timely filing, they need to submit a claim, get a denial and then appeal it. Based on the date they received the correct insurance info for 2016, it will be timely for them.She also said you should call your former doctors office and tell them to pay Labcorp since they failed to fulfill their responsibility to provide accurate demographic info. Im not sure if shes just saying that because she is also mad at doctors offices, lol. But she did say if the doctors office AND insurance paid, the overpayment would be refunded to the doctors office. However, if the doctor explains the mistake was their fault, Labcorp may cancel the collections account immediately. I would add that we work for a much smaller lab and Labcorp is a big, heartless corporation, so YMMV.Good luck!
