Disp fx of neck of unsp talus, subs for fx w malunion

This code signifies a fracture of the talus bone in the ankle, specifically in the neck region, that has healed improperly (malunion) and is still displaced. The exact side (left or right) of the talus is not specified. This diagnosis indicates the patient is receiving follow-up care for this previously treated but complicated fracture.

Use this code for patients presenting for ongoing management, rehabilitation, or evaluation of a talar neck fracture that has healed in an unsatisfactory position, resulting in malunion. This applies when the displacement of the fracture fragments persists despite initial treatment and the patient is no longer in the initial healing phase.

• Ensure documentation clearly states "malunion" and "displaced" for the talar neck fracture.
• Verify that the encounter is for follow-up care, not initial treatment, as indicated by "subsequent encounter."
• If the laterality (left or right) of the talus is documented, select a more specific code.
