Hi, I am from XXXX and I travelled to the XXXX last year in XX/XX/XXXX - XX/XX/XXXX for three weeks. I felt very sick on XXXX XXXX afternoon and went to XXXX XXXX emergency ( in XXXX, CT ). They performed tests, gave me medicine and discharged me in the evening. I gave them my travel insurance details and my XXXX address. 

Yesterday ( XXXX XXXX, 2015 ) I saw a missed call alert on my phone XXXX XXXX XXXX - when I called back on the number - I learned that they are from Optimum Outcomes debt collection agency. The lady on the phone informed that XXXX XXXX forwarded my account to them for debt collection and that I owe them {$4000.00}. 

I then called the hospital and spoke to XXXX XXXX. She informed me that my account was sent for debt collection because insurance company had denied the claim. I told her that hospital had never sent me any EOB or bill or notification of this denial. XXXX XXXX informed me that I was not sent any bill probably because of an XXXX address. 

Can the hospital share my account details with a debt collection agency without giving me any notice? They did n't even send me an EOB. If they had problems in sending communications to XXXX address - they could have asked for a XXXX address ( a friend 's address/office address ) at the time of visit. 

It has been several months since the date of service and I am not sure if the insurance company will entertain the claim. This {$4000.00} equals approx. XXXX XXXX. It is a very large amount that I ca n't afford. If the hospital had informed me of this amount after denial ( they had my home address and email address both ), I could have talked to insurance company in time. 

I am an XXXX citizen living in XXXX. I do not want to have a bad credit history in case I get an opportunity to live in the XXXX in future. 

Requesting your help in this case.
