Displ Maisonneuve's fx unsp leg, 7thH

This code describes a Maisonneuve's fracture, which is a specific type of spiral fracture of the proximal fibula with an associated ankle injury (medial malleolus fracture and/or deltoid ligament rupture, and tibiofibular syndesmosis disruption). In this instance, the fracture is displaced, located in an unspecified leg, and is being treated in a subsequent encounter for an open fracture (Type I or II) that is experiencing delayed healing.

Use this code for follow-up encounters where a patient with a previously diagnosed and treated open Maisonneuve's fracture (Type I or II) of an unspecified leg is presenting with evidence of delayed healing. This applies when the fracture fragments remain displaced.

• Ensure documentation specifies "displaced" and "delayed healing" for an open Type I or II Maisonneuve's fracture.
• Confirm this is a subsequent encounter, not the initial treatment.
• Laterality (left or right) is unspecified for this particular code; if known, a more specific code should be sought.
