Nondisp fx of trapezoid, right wrist, subs for fx w malunion

This code signifies a right wrist injury involving a trapezoid bone fracture that is not displaced, meaning the bone fragments remain in their normal alignment. The patient is in a subsequent phase of care, and the fracture has healed improperly, resulting in a malunion. This indicates a complication where the bone has united in an anatomically incorrect position.

This code is appropriate for follow-up encounters where a patient with a previously diagnosed nondisplaced right trapezoid fracture presents with evidence of malunion. This would typically be identified during imaging studies or clinical examination after the initial healing period. It should be used when the malunion is the primary focus of the encounter for assessment or management.

• Ensure documentation clearly specifies "right wrist" and "trapezoid" bone.
• Verify that the fracture was initially "nondisplaced" and that "malunion" is explicitly documented.
• Confirm this is a "subsequent encounter" for the fracture, not the initial treatment.
