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

This code signifies a right wrist injury involving a break in the trapezoid bone, one of the smaller carpal bones, where the bone fragments remain in their anatomical position. The fracture has failed to heal properly, and the patient is presenting for ongoing treatment of this nonunion.

This code is appropriate for follow-up encounters where a patient is receiving care for a right trapezoid fracture that has not united, and the initial displacement was absent. This includes scenarios such as cast changes, physical therapy, or surgical intervention specifically addressing the nonunion of the previously diagnosed nondisplaced right trapezoid fracture.

• Ensure documentation clearly states "nonunion" and specifies the right wrist and trapezoid bone.
• Verify that the initial fracture was indeed nondisplaced; if displaced, a different code would be necessary.
• This code is for subsequent encounters; an initial encounter for the fracture would use a different code from the same category.
