Mrs. Kelly had an appointment to see the doctor for a persistent low grade fever. During the visit she mentioned that she had twisted her ankle a week or so ago and that it still hurt when she put weight on it. The doctor took X-rays and found that there was a stress fracture. He gave her a post op shoe to wear to provide more support and reduce her pain. When coding this patient’s visit, he used fever for the diagnosis code, and he used X-rays and a post op shoe for the procedure codes. What error did the doctor make when coding?
