Nondisp Maisonneuve's fx unsp leg, 7thP

This code describes a Maisonneuve's fracture, which is a specific type of ankle injury involving a spiral fracture of the proximal fibula with an associated ankle sprain and/or medial malleolar fracture. In this instance, the fracture fragments are still in their normal anatomical alignment (nondisplaced), and the patient is in a subsequent phase of care where the fracture has healed but in a misaligned position (malunion).

Use this code for follow-up encounters when a patient with a previously diagnosed nondisplaced Maisonneuve's fracture of an unspecified leg presents with evidence of malunion. This would apply during ongoing treatment or evaluation of complications related to the fracture's healing.

• Confirm documentation specifies "nondisplaced" and "malunion" for a closed fracture in a subsequent encounter.
• Ensure the medical record clearly indicates a Maisonneuve's fracture, not a general fibula fracture.
• If the specific leg (left or right) is documented, a more specific code should be used.
