Disp fx of med malleolus of unsp tibia, 7thQ

This code describes a fracture of the inner ankle bone (medial malleolus) of an unknown tibia that has shifted out of its normal alignment. This specific code is used for follow-up care of an open fracture (where the bone broke through the skin) classified as Type I or II, and the bone has healed incorrectly (malunion).

Apply this code when documenting subsequent encounters for a patient with a previously treated open medial malleolus fracture (Type I or II) of an unspecified tibia, where the fracture has healed with a noticeable malunion. This would be used for ongoing management, evaluation of the malunion, or planning for corrective procedures.

• Ensure documentation clearly specifies "unspecified tibia" if the laterality is not known.
• Confirm the original fracture was an open fracture, Type I or II, and that malunion is present.
• This code is for subsequent encounters; use an initial encounter code for the original injury.
