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

This code signifies a displaced fracture of the trapezoid bone in the left wrist that has failed to heal properly, resulting in a nonunion. It indicates that the patient is currently receiving care for this unhealed fracture, which is not in its initial treatment phase.

Use this code for patients presenting with a previously diagnosed left trapezoid fracture that has not united and is now being managed in a subsequent encounter. This applies when the physician documents nonunion and the fracture is displaced.

• Ensure documentation clearly states "nonunion" and specifies the left wrist and trapezoid bone.
• Verify that the encounter is for ongoing management of the nonunion, not the initial treatment.
• Confirm the fracture is explicitly documented as "displaced" to use this specific code.
