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

This code signifies a displaced fracture of the trapezoid bone in an unspecified wrist that has healed improperly (malunion). The fracture was previously treated, and the patient is now presenting for follow-up care related to the complication of malunion.

Apply this code when a patient is seen for ongoing management or evaluation of a trapezoid fracture that has united in an anatomically incorrect position. This typically occurs during follow-up appointments after initial treatment, where imaging confirms the malunion.

• Ensure documentation clearly states "displaced fracture" and "malunion" of the trapezoid bone.
• Verify that the encounter is for subsequent care related to the fracture and its complication, not the initial treatment.
• Confirm the specific wrist is not documented, necessitating the "unspecified wrist" designation.
