Displaced subtrochnt fx l femur, subs for clos fx w malunion

This code signifies a left femur fracture located below the lesser trochanter but above the femoral shaft, which has healed improperly (malunion). The fracture was initially displaced, meaning the bone fragments were out of alignment. This specific code is used when the patient is receiving follow-up care for this previously treated fracture.

Use this code for patients presenting for ongoing management, evaluation, or treatment of a malunited subtrochanteric fracture of the left femur. This includes scenarios where the malunion is causing pain, functional limitations, or requires further surgical intervention (e.g., corrective osteotomy) after the initial treatment. It is appropriate for office visits, physical therapy, or imaging studies related to the malunion.

• Ensure documentation clearly states "left femur," "subtrochanteric," "displaced," and "malunion."
• Verify this is a subsequent encounter for the fracture, not the initial treatment or a sequela.
• Do not use this code if the fracture is still acute, nonunion, or if the malunion is located in a different part of the femur.
