Try o make sure all treatments are pre authorized. Without knowing anything about your health insurance contract or coverages, it is impossible to give you advice on a forum. I would have an attorney look over the situation and advise you.
I am sorry to hear about this issue you are currently experiencing. I agree with the previous poster that you should consult someone in your area to discuss the matter.
I would also talk to the hospital administration and determine whether they have a patient's rights advocate. Many hospitals have advocates who can assist with things of this nature.
Sorry to hear about your situation. You could also try talking to the hospital’s social worker; they may be able to assist you.
