Displ Maisonneuve's fx left leg, subs for clos fx w malunion

This code describes a specific type of ankle fracture involving a spiral fracture of the proximal fibula with an associated ankle injury, specifically affecting the left leg. In this instance, the fracture has been previously treated but has healed improperly (malunion), and the patient is presenting for follow-up care or treatment related to this complication.

Use this code when documenting a patient encounter for a left Maisonneuve's fracture that has healed with malunion. This applies to follow-up visits, evaluations for pain or functional limitations due to the malunion, or planning for corrective procedures. The fracture itself is no longer acute, but the malunion is the focus of the current encounter.

• Ensure documentation clearly states "malunion" and specifies the left leg.
• Verify this is a subsequent encounter, not the initial treatment for the fracture.
• Do not use for nonunion; a different code would be appropriate for that complication.
