Patients are entitled to information regarding medical bills

I recently visited the casualty section of this clinic where I was a patient and asked the receptionist for information if I would receive any bills not paid by my medical aid. I was a patient and always feel that as a patient you are entitled to know if you will be responsible for paying any outstanding doctors fees not covered by the medical aid or have a choice to be treated by a doctor that is within the scheme rates. I was rather dissatisfied that I was not given this information prior to being treated as I feel it's highly unfair to be send a bill now as I certainly have not planned for this payment and am currently unemployed.
