Insurance companies will have to accept patients with higher costs (pre-existing conditions), because of ACA’s mandate that everyone must purchase insurance. Insurance companies realize that this mandatory purchase of insurance will bring more healthy customers to them, thus balancing those higher costs associated with pre-existing conditions. If insurance companies deny coverage of pre-existing conditions, approximately 50 million people (including 17 million children), will be without health insurance and cannot afford treatment. This means that they will end up in the emergency room with higher costs, and their expenses will either be paid through Medicaid or have to taken as a loss for the hospital. This results in higher healthcare costs
