Displ intertroch fx unsp femur, subs for clos fx w malunion

This code signifies a previously treated intertrochanteric fracture of the femur that has healed in an unsatisfactory position (malunion). The fracture was displaced at the time of injury, and the current encounter is for follow-up care or management of the malunion, with the skin over the fracture site remaining intact. The specific femur (left or right) is not documented.

Apply this code when a patient presents for ongoing care, evaluation, or treatment related to a malunited intertrochanteric fracture of an unspecified femur. This includes scenarios where the malunion is causing symptoms, requiring further imaging, or being considered for corrective surgery after the initial treatment of the closed fracture.

• Ensure documentation clearly states "malunion" and that the fracture was previously treated as "closed."
• Verify that the encounter is "subsequent" and not for the initial treatment of the fracture.
• If the specific femur is known, a more precise code (e.g., S72.141P or S72.142P) should be used.
