<prompt> Human: So two days ago I received a bill in the mail from a collection agency for 816.30, which completely caught me off guard. Apparently, the bill is from a outpatient drug facility I went to in August of 2013. When I was at the facility, they administed a standard urine test and billed it to my insurance company. I havent thought about it again until I received the bill. Im in a financially tight position at the moment and just as I start to get a little breathing room and pay off a good amount of my debt, I GET THIS. What would happen if I just flat out refused to pay it? Can they, and would they bother, filing a lawsuit against me? I really cant and do not want to pay it so any help would be appreciated. Also, I cannot afford a lawyer.P.S. : I NEVER ONCE received mail regarding information from the original billing company until after they sent to it a collection agency. So I didnt know about the debt until recently.P.S.S The bill isnt for the actual treatment. The bill is from the laboratory they sent the urine sample to for testing. Im paying for the testing.Just contacted the treatment facility and they said it was a clerical error on their behalf!! thank GODDDAssistant: you need to call the treatment center and or the insurance to see why it was not paid by the insurance company first to make sure is is not a billing errorHuman: I didnt have insurance at the time of treatment.  <response>: When I was at the facility, they administed a standard urine test and billed it to my insurance company.Did you or did you not have insurance? Two options: A If you did not have insurance, you need to pay this bill. You were administered services, you have to pay for them. Contact the collections agency and work out a payment plan get it in writing!. OR B If you did have health insurance, you need to contact the treatment center andor the insurance company this should have been billed to and find out if it was supposed to be covered by your insurance, and why it wasnt. If everyone agrees it should have been covered by insurance, let them handle it. If everyone agrees it isntwasnt covered by insurance, see A.
