Disp fx of med malleolus of l tibia, 7thR

This code describes a left ankle injury where the inner bony prominence of the tibia (medial malleolus) is broken and the bone fragments are not properly aligned. This specific instance indicates an open fracture, meaning the skin was broken, and it's a subsequent encounter where the fracture is healing incorrectly, resulting in malunion.

This code is appropriate for follow-up visits where a patient with a previously diagnosed open fracture (Type IIIA, IIIB, or IIIC) of the left medial malleolus is presenting with evidence of malunion. This would typically be used after initial treatment and during the healing phase when the bone is not uniting in an anatomically correct position.

• Ensure documentation clearly specifies "malunion" and not "nonunion" or "delayed union."
• Verify the fracture is explicitly stated as "displaced" and involves the "medial malleolus of the left tibia."
• Confirm the original fracture was an "open fracture type IIIA, IIIB, or IIIC" to justify the specific open fracture type in the code.
