M. Katie Charles, MD, MSPH
Internal Medicine Doctor, Primary Care Doctor
As an internal medicine doctor, I take care of adults from age 18 to the end of life. I see some patients for acute problems, such as the common cold or the flu, and others I see for chronic issues that need monitoring, such as liver problems, heart problems, and diabetes. My philosophy when meeting with patients is that my office is a shared decision-making space. I like to get to know each patient so that I'm able to understand what medical therapies would be appropriate to their life. I also enjoy being able to educate patients on their bodies, why they may start or stop certain medications, and how to live healthy lifestyles. Duke is a special place because we have experts in all different fields. If I need to refer a patient to another specialty, we have surgeons, physicians, radiologists, and other specialists who are at the top of their fields here.

Before scheduling your appointment, we strongly recommend you contact your insurance company to verify that the Duke Health location or provider you plan to visit is included in your network. 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.
