Nondisp fx of med malleolus of l tibia, 7thR

This code signifies a previously treated fracture of the inner ankle bone (medial malleolus) of the left tibia that was initially an open fracture (skin broken) of a severe type (IIIA, IIIB, or IIIC). The fracture itself is currently nondisplaced, but it has healed incorrectly, resulting in a malunion. This code is used during follow-up care for this specific complication.

Apply this code during subsequent encounters for patients who are being managed for a malunion of a nondisplaced left medial malleolus fracture, where the original injury was a severe open fracture. This would include scenarios where the malunion is being monitored, evaluated for corrective surgery, or undergoing non-surgical management. It is appropriate for follow-up visits after the initial healing phase has concluded but the bone has united in an undesirable position.

• Ensure documentation clearly specifies "malunion" and the original fracture type was open IIIA, IIIB, or IIIC.
• Verify the fracture is of the left medial malleolus and is currently nondisplaced.
• This code is for subsequent encounters, not the initial treatment of the fracture or the initial diagnosis of malunion if it's the first time it's being addressed.
