Oth fx shaft of rad, right arm, subs for clos fx w nonunion

This code signifies a fracture of the shaft of the right radius, which is not otherwise specified as a specific type of fracture (e.g., transverse, oblique). The fracture has failed to heal properly, resulting in a nonunion, and the patient is presenting for follow-up care after the initial treatment of the closed fracture.

This code is appropriate for documenting subsequent encounters for a patient with a previously treated closed fracture of the right radial shaft that has developed a nonunion. This would include visits for ongoing management, evaluation of nonunion, or preparation for surgical intervention to address the nonunion.

• Ensure documentation clearly states "nonunion" and specifies the right arm and radial shaft.
• Verify that the encounter is for subsequent care of a closed fracture, not an open one.
• Differentiate from malunion, which has a separate code.
