Disp fx of med malleolus of unsp tibia, 7thR

This code signifies a malunion of a previously sustained, displaced fracture of the medial malleolus of an unspecified tibia. The original injury was an open fracture, classified as type IIIA, IIIB, or IIIC, indicating significant soft tissue damage and bone exposure. Malunion means the fracture has healed in an unsatisfactory position, leading to functional impairment or deformity.

This code is appropriate for subsequent encounters when a patient presents with a healed but improperly aligned displaced medial malleolus fracture that was originally an open fracture of types IIIA, IIIB, or IIIC. This would include follow-up appointments for assessment of the malunion, planning for corrective surgery, or managing complications arising from the malunion.

• Ensure documentation clearly specifies "malunion" and the original open fracture type (IIIA, IIIB, or IIIC).
• Confirm the fracture is of the medial malleolus and that it was displaced.
• This code is for subsequent encounters; an initial encounter for the malunion would use a different code.
