Nondisp Maisonneuve's fx unsp leg, 7thR

This code describes a 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 often disruption of the tibiofibular syndesmosis. In this instance, the fracture fragments are in their anatomical position (nondisplaced), and the patient is receiving care for a previously open fracture that is now healing improperly (malunion).

Use this code for follow-up encounters where a patient with a previously diagnosed nondisplaced Maisonneuve's fracture of an unspecified leg, which was initially an open fracture (Type IIIA, IIIB, or IIIC), is being treated for malunion. This indicates the fracture is healing in an unsatisfactory position, requiring ongoing medical management.

• Ensure documentation specifies "nondisplaced" and "Maisonneuve's fracture" for accurate code assignment.
• Verify the encounter is for a subsequent visit and that malunion is explicitly documented as the reason for the encounter.
• Confirm the original fracture was classified as an open fracture type IIIA, IIIB, or IIIC.
