Disp fx of ant pro of r calcaneus, subs for fx w nonunion

This code signifies a break in the front part of the right heel bone that is no longer in its proper anatomical alignment. It specifically indicates that the fracture has failed to heal after an initial treatment, and the patient is presenting for ongoing management of this nonunion.

Apply this code when a patient presents for follow-up care of a previously diagnosed displaced fracture of the anterior process of the right calcaneus, and documentation clearly states that the fracture has not united. This would include scenarios where surgical intervention for nonunion is being planned or conservative management for nonunion is ongoing.

• Ensure documentation explicitly states "nonunion" for the fracture.
• Verify the laterality (right) and the specific bone (calcaneus) and process (anterior).
• Confirm that this is a subsequent encounter, not the initial treatment for the fracture.
