Displaced pilon fx right tibia, subs for clos fx w nonunion

This code signifies a right tibia fracture involving the weight-bearing surface of the distal tibia (pilon fracture) where the bone fragments are not in their anatomical position. It specifically indicates that the patient is receiving follow-up care for this fracture, which has failed to heal properly and is currently managed non-surgically.

Apply this code when a patient presents for ongoing treatment of a previously diagnosed, displaced right pilon fracture that has developed into a nonunion, and the current encounter involves conservative management (e.g., cast changes, physical therapy, medication management for nonunion). This is appropriate for subsequent visits after the initial treatment of the fracture.

• Ensure documentation clearly states "nonunion" and "displaced" for the right pilon fracture.
• Verify the encounter is for subsequent care, not initial treatment or sequela.
• Confirm the fracture is being treated non-surgically; surgical intervention for nonunion would typically use a different encounter type.
