Displaced Maisonneuve's fracture of unspecified leg, sequela

This code signifies a displaced Maisonneuve's fracture, which is a specific type of ankle fracture involving a spiral fracture of the proximal fibula with an associated injury to the deltoid ligament and/or medial malleolus, and disruption of the tibiofibular syndesmosis. The "sequela" designation indicates that this code is used for complications or conditions arising directly from the initial injury, after the acute phase of healing has passed.

Use this code when documenting a long-term complication or residual condition directly attributable to a previously sustained, displaced Maisonneuve's fracture of an unspecified leg. This could include chronic pain, instability, malunion, nonunion, or post-traumatic arthritis. This code is appropriate for follow-up encounters addressing these lasting effects.

• Always sequence this code after the code for the specific sequela being treated (e.g., M25.57- for chronic ankle pain).
• Ensure documentation clearly links the current condition to the previous Maisonneuve's fracture.
• Confirm the fracture was indeed "displaced" and that the leg was "unspecified" if no laterality is documented.
