In the medical billing and coding field, getting paid requires accurate documentation and selecting the correct codes. In our Coding Case Studies, we explore the correct coding for a specific condition based on a hypothetical clinical scenario. This scenario involves a patient presenting for a follow-up visit with symptoms of Type 2 Diabetes. See if you can choose the correct codes.
