Oth fx of lower end of r radius, subs for clos fx w nonunion

This code signifies a fracture affecting the lower portion of the right radius, excluding specific types like Colles' or Smith's, that is currently in a healing phase but has failed to unite properly. The fracture was initially closed, meaning the skin was not broken at the time of injury, and the patient is presenting for follow-up care related to this ongoing complication.

Apply this code when documenting subsequent encounters for a patient with a previously diagnosed, non-specific fracture of the distal right radius that is now complicated by nonunion. This would be appropriate for office visits, hospital outpatient visits, or other follow-up care where the primary focus is managing the nonunion of the closed fracture.

• Ensure documentation clearly specifies "nonunion" and that the fracture is of the "lower end" or "distal" radius, and on the "right" side.
• Verify that this is a subsequent encounter, not the initial treatment for the fracture.
• Confirm the fracture was initially closed; if open, a different code would be required.
