Nondisp fx of body of unsp talus, subs for fx w malunion

This code signifies a fracture of the main part of the talus bone in the ankle that was not initially displaced, but has since healed improperly. "Malunion" indicates that the bone fragments have joined in a deformed position, which may lead to ongoing pain or functional impairment. This is a follow-up encounter for a previously diagnosed injury.

Use this code when documenting a patient visit for a previously treated nondisplaced talar body fracture that has healed with an unsatisfactory alignment. This typically occurs during follow-up appointments where imaging confirms malunion, or when the patient presents with symptoms related to the malformed healing. It is appropriate for ongoing management, evaluation of complications, or planning for corrective procedures.

• Ensure documentation clearly states "malunion" and specifies the "body" of the talus.
• Verify that the initial fracture was indeed nondisplaced; otherwise, a different malunion code may be appropriate.
• Always sequence this code after any relevant external cause codes or codes for associated complications.
