Nondisp trimalleol fx l low leg, 7thQ

This code signifies a malunion of a trimalleolar fracture in the left lower leg, which was initially an open fracture (Gustilo type I or II) and is now in a subsequent encounter phase. A trimalleolar fracture involves the medial, lateral, and posterior malleoli, indicating significant ankle instability. Malunion implies the fracture has healed in an anatomically incorrect position.

Apply this code when documenting follow-up care for a patient whose left trimalleolar open fracture (type I or II) has healed with an unsatisfactory alignment. This would be used for ongoing management of the malunion, such as evaluating for surgical correction, pain management, or physical therapy addressing the functional limitations caused by the malalignment.

• Ensure documentation clearly specifies "malunion" and the "left" lower leg.
• Verify the initial fracture was an "open fracture type I or II" to justify this specific subcategory.
• Confirm this is a "subsequent encounter" and not an initial treatment for the malunion itself.
