Disp fx of trapezium, right wrist, subs for fx w nonunion

This code signifies a right wrist injury involving a fracture of the trapezium bone that is out of alignment, and the patient is presenting for ongoing care because the fracture has not healed properly. This indicates a complication in the healing process of the initial displaced trapezium fracture.

This code is appropriate for follow-up encounters where a patient with a previously diagnosed displaced right trapezium fracture is being treated for nonunion. This includes scenarios such as surgical intervention for nonunion, casting/splinting adjustments, or evaluation of ongoing conservative management for the unhealed fracture.

• Ensure documentation clearly states "nonunion" and specifies the right wrist and trapezium.
• Verify that the initial fracture was indeed displaced.
• This code requires an additional code for any associated external causes of morbidity, if applicable.
