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

This code signifies a previous fracture of the shaft of the left femur that has healed in an unsatisfactory alignment, resulting in a malunion. The patient is currently presenting for follow-up care or treatment related to this malunion, and the original fracture was a closed type.

Apply this code when a patient with a documented history of a closed left femoral shaft fracture is seen for ongoing management of a malunion. This includes visits for physical therapy, imaging to assess the malunion, or discussions regarding surgical correction of the malunion. It is used for subsequent encounters after the initial treatment of the fracture.

• Ensure documentation clearly specifies "left femur" and "shaft" to differentiate from other femoral fracture locations.
• Verify that the encounter is for a "subsequent" visit related to the malunion, not the initial fracture treatment.
• Confirm the original fracture was "closed" as indicated in the patient's history.
