I went to the Emergency Room on XXXX/XXXX/13, which after the services were rendered I submitted to them my Health Insurance Information and proper Government ID. After approximately a year had passed I started receiving bills from the XXXX XXXX XXXX, stating I owed them {$910.00} which is the original full amount billed as if I had no Health Insurance. I had paid my {$300.00} copay which was my portion of financial responsibility for that XXXX. visit according to XXXX. I called XXXX to find out why the XXXX was billing me. I was told by XXXX that the XXXX had sent their claim to the wrong billing address and that 's why the claim has not been paid. XXXX stated that there were XXXX different billing addresses on the back of the I.D . card, XXXX for the XXXX and a different XXXX for the XXXX. I called the XXXX billing office to inform them that they were sending their claim to the incorrect address. The person I spoke to with the XXXX 's office told me they would resubmit the claim. Several months had passed and I started receiving bill 's again. I called XXXX and was told once again that they were still sending their claim to the incorrect address. The XXXX representative was kind enough to put me on hold while she called the XXXX 's office to give them the correct billing address. When the XXXX representative took me off hold, she informed me that it should be taken care of, but to call back in 3-4 weeks to verify. Again, I started receiving bills from the XXXX 's office. I decided to file a complaint with the XXXX, after doing that the XXXX 's office turned me over to Collections. By this point another year has passed, so it 's been about 2 years since my XXXX. I contacted the Collection Agency and tried to explain to them there was an Administrative error made on the XXXX 's billing office, that they had not sent the claim to the correct address. I then decided to call XXXX back to get the correct billing address myself to give it to the XXXX 's office personally instead of trying to use XXXX as a go between. When I called the XXXX 's office I gave them the correct address and told them to please resubmit the claim. After the XXXX 's office finally submitted the claim to the correct address, the claim was denied on the basis of not being Filed in a Timely Manner. According to Texas ' State Law if a Medical Claim is not filed in a Timely Manner then the claim must be absorbed or written off internally by the Organization. It no longer is the responsibility of the Insured if the XXXX 's billing office makes a mistake and does not file the claim in a Timely Manner. Because, the claim is still unpaid the Collection Agency has put this on my Credit Report. I have personally seen negative reporting with XXXX and XXXX XXXX. My Credit score has suffered as a result of their Administrative error as well. Justice needs to be served in this situation. They need to pay to have my Credit repaired and good name restored. I have not been able to get anybody at the Collection Agency or the XXXX 's billing office to listen to any reason. They just want their money and do n't care about anything else. The worst thing about this is I had Insurance, I submitted it to them at the time services were rendered, I paid my copay for an XXXX, yet they are still trying to bill me for the full amount, as if I had no Insurance at all. I have done everything I was suppose to do as an Insured patient. They are the ones that failed to do their job right, someone internal of their Organization failed to read on the back of my I.D . card to get the correct billing address & this whole time they have been trying to make me pay as a result of their mistakes.
