Displaced dome fx left talus, subs for fx w malunion

This code signifies a fracture of the dome (superior articular surface) of the talus bone in the left foot, which has shifted from its normal anatomical position. The fracture has healed incorrectly, resulting in a malunion, and the patient is presenting for follow-up care related to this complication.

This code is appropriate for encounters where a patient with a previously diagnosed and treated displaced dome fracture of the left talus is being seen for management of a malunion. This includes visits for assessment of the malunion, planning for corrective surgery, or ongoing conservative management of symptoms related to the malunion.

• Ensure documentation clearly specifies "left" talus and "displaced" fracture.
• Verify that the encounter is for a "subsequent" visit related to the malunion, not the initial treatment of the fracture.
• Confirm that the malunion is explicitly documented as a complication of the fracture healing.
