"Just to get this straight, please correct me if I'm wrong, they cannot deny you care then in the Emergency Room, but they can in any other case."
There is a common misconception that because physicians are in the medical field "taking care" of people that they must accept a patient under any and all circumstances. That is not the case. While they are in a care providing service they are also business people and as such can make decisions as to which patients they can provide services to. Most decisions are made based on two criteria: 1) can they provide the necessary medical care the patient needs within their scope of training, and (2) is the patient compliant with the physician in their care. For example: under #1: if the doctor has no training in cardiology then he is not obligated to treat the patient's heart problems; under #2 if the patient is non-compliant about taking medication, drug seeking, owes too much money to the doctor, or does not keep appointments etc. then the physician may discharge them from care with 30 days written notice and supply of medication if necessary.
Emergency room care is an entirely different model. When a patient arrives to an ER they are entitled to be evaluated and stabilized regardless of their ability to pay or reason for seeking treatment. Once medically stable the ER must either admit the patient or they may discharge them with instructions for follow up care.
