Displaced dome fx unsp talus, subs for fx w malunion

This code signifies a fracture of the dome of the talus bone that has shifted from its normal anatomical position and is currently healing improperly, resulting in a malunion. This specific code is used when the laterality of the talus (left or right) is not documented.

Apply this code for follow-up encounters where a previously diagnosed displaced talar dome fracture is being treated for a malunion, and the specific talus involved (left or right) is not specified in the medical record. This would typically be used after initial treatment, during ongoing management of the healing process.

• Ensure documentation explicitly states "malunion" for the subsequent encounter.
• Verify that the laterality of the talus is truly unspecified before using this code; otherwise, a more specific code should be chosen.
• This code indicates a displaced fracture; if the fracture was nondisplaced, a different code would be appropriate.
