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

This code signifies a subtrochanteric fracture of the femur, located below the lesser trochanter but above the femoral shaft, that has healed improperly (malunion). The fracture is displaced, meaning the bone fragments are not in their normal alignment. This specific code is used when the patient is receiving follow-up care for this closed fracture.

Apply this code for patients presenting for ongoing treatment, rehabilitation, or evaluation of a previously sustained and now malunited subtrochanteric femoral fracture. This includes scenarios where the patient is experiencing complications related to the malunion, such as pain or functional limitations, and the fracture was initially treated non-surgically or has since closed.

• Ensure documentation clearly states "malunion" and that the encounter is subsequent for a closed fracture.
• Verify the fracture location is specifically subtrochanteric.
• Do not use for initial encounters or for open fractures.
