Disp fx of trapezoid, left wrist, subs for fx w malunion

This code signifies a fracture of the trapezoid bone in the left wrist that has healed improperly, resulting in a deformity or misalignment. This specific code is used when the patient is seen for ongoing management of this malunion, not the initial injury or routine healing.

Apply this code when a patient presents for evaluation or treatment of a previously fractured left trapezoid bone that has healed in a misaligned position. This includes follow-up appointments for corrective surgery planning, physical therapy for functional deficits due to malunion, or monitoring of the malunion's impact on wrist function.

• Ensure documentation clearly states "malunion" and specifies the left trapezoid bone.
• Verify this is a subsequent encounter, not the initial treatment of the fracture.
• Always look for additional codes to describe any associated complications or ongoing treatment.
