Your insurance company will also be able to inform you of any co-payments, co–insurances, or deductibles that will be your responsibility. If you proceed in scheduling an appointment and your health insurance benefits do not participate with Duke, your out of pocket liability may be higher. We will contact you regarding your coverage and patient liability. If you are uninsured, learn more about our financial assistance policy.
