I went to get a CT scan at the XXXX XXXX XXXX Hospital. They called the insurance company to get pre approval. I asked the woman who called the insurance company and she said yes you are approved. I further asked her if I owed anything and she said no. When I called the collections dept at XXXX the woman was belligerent and said well the woman never said you were covered 100 % - she quibbled over words but to me not owing anything and 100 % is a difference without distinction. The fact is that the lady who called the insurance company was an agent of the hospital. When I asked her professional opinion she gave me the wrong information. They are telling me I owe them XXXX which is unfair b/c had I known that I would owe my own money toward the service I never would have had it done. I am deeply troubled by their comments/attitude/lack of knowledge. If someone deals with insurance companies and are asked if they are 'covered ' and if I would owe anything than their answer should be able to be relied upon.
