I had XXXX on XX/XX/XXXX. After paying over {$2000.00} out of pocket for the different XXXX supplies, etc., I received a bill from the hospital for $ XXXX. I contact XXXX about the bill and found that XXXX denied the claim for 'lack of medical records ' on XX/XX/XXXX. An 'EOB ' was generated on XX/XX/XXXX. The same claim was adjusted for payment on XX/XX/XXXX. Another EOB was generated on XX/XX/XXXX. The same claim was adjusted on XX/XX/XXXX, but there was no change in payment, so no EOB was issued. The claim was again adjusted on XX/XX/XXXX, but again no change in payment so no EOB. The claim was adjusted again on XX/XX/XXXX which reduced the payment XXXX paid from {$2700.00} to {$1900.00}. Even though there was a change in payment, NO EOB was generated. This entire time, XXXX kept advising me to pay my copay of {$45.00}, which I promptly did. XXXX specifically told me not to pay the hospital any other amount. Because of this nightmare, the hospital sent my bill to a collections agency. Not once did XXXX contact me to advise of their mistakes when processing the claim. I only found out about this when I began receiving calls, up to XXXX times a day, from the collection agency. The hospital was tired of waiting for my insurance to straighten out their errors, so they sent the original bill from XX/XX/XXXX to collections. Now, my credit rating has been effected and I am constantly receiving calls and letters for a claim that has been adjusted numerous times. I do n't even know where to start. I have begun the process of filing executive complaints against the insurance company and the hospital for failing to process the adjusted claims. I have also submitted a verification of debt and request for all correspondence in writing letter to the collections agency. I have also initiated complaints through the Consumer Financial Protection Bureau, the Florida State Attorney General, and the local XXXX. This company is ripping off consumers and hoping that people get fed up with the complicated processes and just give up and pay an incorrect bill. Disgusting. I want XXXX to admit their error, contact the hospital to pull back the debt from the collections agency and correct the claim at the hospital so that I can receive a correct bill for my surgery, performed over a year ago, pay the bill and be done with this nightmare.
