Incomplete atypical femoral fracture, right leg, 7thP

This code signifies an incomplete atypical femoral fracture located in the right leg, which has progressed to a state of malunion. An atypical femoral fracture is a rare stress fracture that occurs in the subtrochanteric region or femoral shaft, often associated with long-term bisphosphonate use. Malunion indicates that the fracture has healed in an unsatisfactory position, potentially leading to functional impairment.

Use this code for a patient presenting for follow-up care of a previously diagnosed incomplete atypical right femoral fracture that has healed incorrectly. Documentation should clearly state the presence of an atypical femoral fracture, its location on the right leg, and the specific finding of malunion during a subsequent encounter. This code is appropriate when the patient is receiving active treatment for the malunion or its complications.

• Ensure documentation specifies "incomplete" and "atypical" to differentiate from other femoral fractures.
• Verify the encounter type is "subsequent" and that malunion is explicitly documented, not just delayed healing.
• Always sequence this code after any underlying cause or contributing factor, such as long-term bisphosphonate use (e.g., T38.81XA).
