I had a XXXX on XXXX XXXX 2011. I was put in an XXXX for 7 days and received excellent care. 

Well, the bills start rolling in. I get a XXXX dollar bill from the hospital, and almost have another XXXX XXXX ( XXXX XXXX ). Because being retired military I thought I was covered. I went to my XXXX office and they laughed ... and so did I after they told me what my responsibility was. 
I then paid my deductibles in full ... thinking that my financial responsibility was fulfilled. Then, after the XXXX I personally hired a credit agency to monitor my credit, and I received a notice that a collection was filed against me by the XXXX XXXX XXXX XXXX XXXX XXXX that was being collected by Business Professionals ( BP ) XXXX 

After contacting BP XXXX I found out that the original billing company did n't have my insurance information and they said the original creditor ( XXXX ) did n't have access to my information in time to file a claim due to HIPA laws. But my insurance XXXX XXXX XXXX says that my only responsibility is to provide my information to the XXXX hospital, and it is the billing agency 's responsibility to garner that information from the hospital. After I came home from the hospital, I made my insurance information readily available to anyone who contacted me, and I paid my co-pays in a responsible manner. 
Now, the collection agency is telling me that I am responsible for the entire bill, even though the agency that supposedly is billing me has no record of my care, account, or even billing me at all. I feel this is unfair and borderline corrupt. If the original agency can not even reproduce an account or bill that they sent me, how can I tell if this an actual debt?
