Oth fx shaft of unsp femur, subs for clos fx w malunion

This code signifies a follow-up encounter for a previously sustained fracture of the femoral shaft, where the specific location on the shaft is not documented. The fracture has healed in an unsatisfactory position, known as a malunion, and the skin over the fracture site was intact at the time of the initial injury.

Use this code when a patient presents for ongoing management or evaluation of a malunited closed fracture of the femoral shaft. This typically occurs after the initial treatment phase, when imaging confirms improper alignment of the bone fragments. It is appropriate for subsequent visits related to the malunion, such as for pain management, physical therapy, or surgical planning for corrective osteotomy.

• Ensure documentation clearly states "malunion" and that the encounter is "subsequent" to the initial injury.
• Confirm the fracture was "closed" at the time of the initial injury.
• If the specific part of the femoral shaft is known (e.g., proximal, distal), a more specific code should be used.
