Displ Maisonneuve's fx unsp leg, 7thQ

This code describes 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. In this instance, the fracture is displaced, located in an unspecified leg, and is currently being treated for a malunion that occurred after an initial open fracture of type I or II.

Use this code for a patient presenting with complications from a previously treated open Maisonneuve's fracture, specifically when malunion is identified. This applies during follow-up visits or when the patient is admitted for management of the malunion, such as surgical correction or further evaluation. The initial open fracture must have been classified as Type I or II.

• Ensure documentation clearly states "malunion" and specifies an "open fracture type I or II" in the patient's history.
• Confirm the fracture is indeed a Maisonneuve's fracture and not another type of ankle or lower leg fracture.
• This is a "subsequent encounter" code; do not use for the initial treatment of the fracture.
