Oth fracture of left lower leg, subs for clos fx w malunion

This code signifies a fracture in the lower part of the left leg, excluding the ankle and specific tibia/fibula shaft fractures, that is currently healing improperly. The fracture was initially closed, meaning the skin was not broken, and the patient is now in a later stage of care where the bone fragments have united in an anatomically incorrect position.

Apply this code when a patient presents for follow-up care of a left lower leg fracture (other than ankle or specific tibia/fibula shaft) that has healed with a noticeable deformity or angulation. This is appropriate for patients undergoing treatment for the malunion itself, or for complications arising from the malunion, after the initial fracture treatment.

• Always confirm the laterality (left) and the specific location of the "other" lower leg fracture.
• Ensure documentation clearly states "malunion" and that the initial fracture was closed.
• Pair with external cause codes (V, W, X, Y) and place of occurrence codes (U) if applicable and documented.
