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

This code signifies a fracture of the shaft of the right radius that is not further specified as a Monteggia, Galeazzi, or Salter-Harris fracture, and has healed in a misaligned position. The patient is presenting for follow-up care or treatment related to this malunion, and the fracture itself is no longer open.

Apply this code when a patient with a previously diagnosed and treated closed fracture of the right radial shaft presents with evidence of malunion. This would typically be used during subsequent visits for assessment, physical therapy, or surgical planning to correct the malalignment.

• Ensure documentation clearly specifies "right arm" and "shaft of radius."
• Verify the fracture is documented as "closed" and that "malunion" is present.
• Confirm this is a "subsequent encounter" for the fracture, not the initial treatment.
