XXXX/XXXX/XXXX XXXX XXXX referred XXXX bills for services to a collection company, Interstate Collection Inc. After examining the explanation of benefits and speaking to a representative from my health insurance company, it was determined that the dates of service and fees are erroneous. I wrote a letter to the collection company denying bill. I also spoke directly to a customer service representative from XXXX hospital billing office by phone. When I quoted the dates of service and fees listed on bill the representative stated that she did not have that information in the system. Letters and phone conversations have been unsuccessful in getting this matter resolved. This negative information will affect my credit rating and impact the interest rate. 
Listed Below is the bill information Date of service : XXXX/XXXX/XXXX {$180.00} Date of service : XXXX/XXXX/XXXX {$20.00} Date of service : XXXX/XXXX/XXXX {$100.00} Date of service : XXXX/XXXX/XXXX {$170.00} My health insurance company mails me an explanation of payments which listed the fees they pay and the any cost that I am responsible for. I reiterate -- the insurance company has stated that they do not have any information for dates and fees listed above. I am responsible for deductibles and copays.
