XX/XX/XXXX I had a medical procedure completed at XXXX XXXX in XXXX, IL ( part of XXXX and recently acquired by XXXX XXXX ). At the time I had the procedure done, I thought I had insurance. Since I had not received a bill from the hospital, I did not know there was anything still outstanding. 

In XX/XX/XXXX ( over 2 years later ), XXXX sent me a bill for the first time stating that XXXX XXXX XXXX XXXX ( XXXX ) had paid the bill, then took the money back on XX/XX/XXXX. 

I immediately called XXXX and filled a hardship application, which was approved for 100 % financial assistance on XX/XX/XXXX. 

I also filed a complaint with the Illinois Department of Insurance ( IDOI ) against XXXX. My claim against XXXX was reviewed, and they repaid the insurance portion on XX/XX/XXXX. 

I immediately contacted XXXX XXXX to inform them that my efforts had resulted in them recouping the {$4400.00} back from XXXX. XXXX XXXX acknowledged that they received the XXXX payment. 

On XX/XX/XXXX, XXXX XXXX issued me an invoice for the 20 % co-pay that XXXX did not cover {$240.00}, even though the entire amount of {$4700.00} had previously been written off. 

On XX/XX/XXXX, I received a collection notice from Nationwide Credit and Collections for the same {$240.00} - even though I have a written letter from XXXX XXXX stating that I owed nothing. The financial assistance letter states it is good for XXXX months, so clearly it is still in force. In addition, my account was sent to collections apparently the same day I was sent the invoice ; and I was never even given an opportunity to resolve the issue with XXXX XXXX before they sent my account to collections. 

Also on XX/XX/XXXX I attempted to contact a manager at XXXX XXXX / XXXX XXXX, because clearly there is a procedural problem with their billing department. When I called the billing number XXXX, I was told that I could not have that information. I have tried searching online for the information and there is no clear way to contact anyone at the executive level to bring this to their attention.
