I was in an accident almost 4 years ago. The person who caused the accident had no insurance and I didn't have uninsured motorist coverage. I'm still paying for some of the medical bills. However one of the bill that I thought was paid by my PIP was not. We had never received a bill from them. They were a radiology office and they just sent us a bill olmost 4 years ater showing a bill of $1,046.07 with PIP having paid $926.67 back in May of 2005 and billing us for $209.21, which includes late penalty. We found out that this company filed for bankrupcy in No. 0f 08. Do we have to pay this after so much time?
