Oth physl fx upper end rad, left arm, subs for fx w malunion

This code signifies a fracture of the growth plate (physis) at the upper end of the left radius, which is not further specified as Salter-Harris types I-IV. The fracture has healed in an unsatisfactory position, resulting in malunion, and the patient is presenting for follow-up care related to this ongoing issue.

This code is appropriate for subsequent encounters when a patient is being managed for a previously diagnosed, unspecified physeal fracture of the proximal left radius that has healed incorrectly. This includes follow-up appointments for assessment of the malunion, planning for corrective procedures, or monitoring conservative management of the malunited fracture.

• Ensure documentation clearly specifies "left arm" and "malunion" for the subsequent encounter.
• Verify that the fracture is indeed of the physis and not another part of the radius.
• Confirm that the encounter is for follow-up care related to the malunion, not initial treatment or routine healing.
