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

This code signifies a fracture of the front part of the left heel bone (calcaneus) that is out of alignment. The fracture has not healed properly, and the patient is presenting for ongoing treatment related to this nonunion.

Apply this code for follow-up visits where a patient is receiving care for a previously diagnosed displaced anterior calcaneal fracture on the left foot that has failed to unite. This includes scenarios such as cast changes, physical therapy, or surgical planning for nonunion.

• Ensure documentation specifies "left" calcaneus and "anterior process."
• Confirm the fracture is explicitly documented as "displaced" and in a "nonunion" healing stage.
• This is a subsequent encounter code; do not use for initial treatment of the fracture.
