Big banks such as Chase, Citicorp and GE Money Bank offer credit cards specifically for use at doctor offices and hospitals. These Medical Credit Cards often carry unfavorable interest rates according to Consumer Reports and are pushed by doctors and hospitals who receive incentives. AARP suggests its members avoid the cards entirely.
Think about this. If you are using a medical credit card to pay for your treatment, then you probably do not have medical insurance coverage. If you do not have coverage, then you probably cannot afford the high cost of medical treatment. So, you are destined to default on the medical credit card debt. Putting your medical debt on a high interest rate credit card will only increase the chance of your not being able to pay the bill.
Banks used to be good for giving customers toasters and blenders, but stay away from those credit card offers.
