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

This code signifies a non-healing fracture of the trapezoid bone in the right wrist that was initially displaced. Nonunion indicates that the bone fragments have failed to unite after a significant period, requiring further medical intervention. This diagnosis is typically made after initial treatment attempts have not resulted in bone healing.

Apply this code for follow-up encounters where a patient is being treated for a previously diagnosed displaced right trapezoid fracture that has progressed to nonunion. This includes visits for evaluation of nonunion, planning for revision surgery, or ongoing conservative management of the nonunion. It is used when the fracture is not actively healing.

• Ensure documentation clearly states "nonunion" and specifies the right wrist and trapezoid bone.
• Verify the fracture was initially displaced; if not, a different subcategory may be appropriate.
• This code is for subsequent encounters, not the initial treatment of the acute fracture.
