Nondisp fx of med malleolus of unsp tibia, 7thR

This code signifies a nondisplaced fracture of the medial malleolus of the tibia, which is a break on the inner ankle bone that has not shifted out of alignment. It specifically applies when the initial injury was an open fracture (skin broken) of a severe type (IIIA, IIIB, or IIIC), and the patient is now being treated for a complication where the bone has healed in an incorrect or deformed position (malunion).

Use this code for follow-up encounters where a patient is receiving care for a previously sustained, severe open medial malleolus fracture that has healed with malunion. This would include situations like planning for corrective surgery, monitoring the malunion, or managing associated symptoms. It is appropriate when the fracture itself is nondisplaced, but the overall healing process has resulted in a malunion from the initial open injury.

• Ensure documentation clearly specifies "nondisplaced" for the medial malleolus fracture.
• Verify the original injury was an "open fracture type IIIA, IIIB, or IIIC" and that "malunion" is present.
• This code is for subsequent encounters, not the initial treatment of the fracture.
