Torus fx upper end of left fibula, subs for fx w nonunion

This code signifies a buckle fracture, or torus fracture, affecting the upper portion of the left fibula. It specifically indicates that the patient is in a subsequent phase of care for this fracture, and the fracture has failed to heal properly, resulting in a nonunion.

Use this code when documenting follow-up care for a patient with a previously diagnosed torus fracture of the proximal left fibula who is experiencing a nonunion. This applies to situations where the fracture site shows no signs of healing progression after an expected period, or has ceased healing altogether.

• Ensure documentation clearly specifies "torus fracture" and "nonunion" for the left fibula's upper end.
• Verify that this is a subsequent encounter, not the initial treatment for the fracture.
• Always review the medical record for laterality (left vs. right) and the specific bone involved.
