Displ Maisonneuve's fx unsp leg, 7thR

This code describes a specific type of ankle fracture where the fibula is broken high up near the knee, often with associated ankle ligament damage, and the bone fragments are not properly aligned. This particular instance indicates a severe open fracture (types IIIA, IIIB, or IIIC) that has healed incorrectly, resulting in malunion.

Use this code for a patient presenting for follow-up care of a Maisonneuve's fracture of an unspecified leg that was initially an open fracture of a severe type (IIIA, IIIB, or IIIC) and has subsequently healed with malunion. This applies to ongoing management, assessment of the malunion, or planning for corrective procedures after the initial healing phase.

• Ensure documentation specifies an open fracture type IIIA, IIIB, or IIIC and explicitly states malunion.
• Verify that the encounter is for subsequent care, not the initial treatment of the fracture.
• Laterality (left or right leg) is unspecified in this code; if known, a more specific code should be sought.
