Disp fx of neck of right talus, subs for fx w nonunion

This code signifies a fracture of the neck of the right talus bone that is no longer in its proper anatomical alignment. It specifically indicates that the fracture has failed to heal properly and is being treated during a follow-up encounter.

This code is appropriate for patients presenting for ongoing management of a previously diagnosed displaced right talar neck fracture where imaging or clinical assessment confirms nonunion. It would be used for subsequent visits after the initial treatment, such as cast changes, follow-up X-rays, or discussions regarding surgical intervention for the nonunion.

• Always confirm laterality (right) and the specific bone (talus) and location (neck).
• Ensure documentation clearly states "nonunion" and that it's a subsequent encounter, not the initial treatment.
• Pair with external cause codes (e.g., V00-Y99) if the cause of the fracture is known and relevant to the encounter.
