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

This code signifies a previously treated fracture of the neck of the left talus that has healed in an anatomically incorrect position (malunion). The fracture was initially displaced, meaning the bone fragments were not properly aligned at the time of injury. This malunion can lead to ongoing pain, functional limitations, and altered biomechanics of the ankle and foot.

Apply this code when a patient presents for follow-up care of a malunited displaced fracture of the left talar neck. This includes visits for assessment of the malunion, planning for corrective surgery, or management of symptoms related to the improper healing. It is used after the initial treatment phase for the acute fracture has concluded.

• Ensure documentation clearly states "malunion" and specifies the left talus neck.
• Verify that the fracture was initially displaced, as this is a specific characteristic of this code.
• This code is for subsequent encounters; do not use it for the initial treatment of the acute fracture.
