<prompt> Human: I went to the doc months ago for a pain and they wanted to do some blood work just in case, I was specifically told I was covered on the entire process and it would only cost me 15 for the blood work.Now Im getting a bill from the diagnostics lab and apparently a collections agency has taken it. What options do I have? Edit: The collection notice lists the 221 charge from 831, and on my billing statement from the doctors office I have an outstanding balance of 28 from 831, but I wont be able to contact the lab until Monday.08312017 OFFICE OR OTHER OUTPATIENT VISIT FOR THEEVALUATION AND MANAGEMENT OF XXX95.0009132017 Insurance Payment: BCBS-SC Processed -42.4409132017 Insurance Adjustment: BCBS-SC Processed -24.28Patient Balance - Coinsurance 28.28Edit part 2: Collections agency has informed me the bill stemmed from my insurance declining paying for the lab work. I guess my next option is to dispute it with the insurance company. I appreciate the advice, everyone. Edit part 3: The lab my blood was sent to definitely accepts my insurance. Thank you all for the insight, Im still reading everything.  <response>: First always always ask your insurance carrier regarding any medical treatment ahead of time before hand, to make sure its considered medically necessary and its going to be covered.Second- make sure you always stay in network.In this case, I highly advise that you file and appeal with your insurance company, and even go as far a filing a complaint with the AGs office as a last resort.
