Disp fx of med malleolus of l tibia, 7thK

This code signifies a left ankle injury involving a break in the inner bony prominence of the tibia, where the bone fragments are not properly aligned. The fracture has failed to heal correctly, and the patient is presenting for follow-up care or treatment of this ongoing issue.

Apply this code when a patient with a previously diagnosed displaced medial malleolus fracture of the left tibia is seen for management of a confirmed nonunion. This includes visits for cast changes, imaging to assess nonunion progression, or discussions regarding surgical intervention for the nonunion.

• Ensure documentation clearly states "nonunion" and specifies the left medial malleolus.
• Confirm the fracture is described as "displaced" and the encounter is "subsequent."
• Do not use for initial fracture treatment or for malunion, which is a different complication.
