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

This code signifies a follow-up encounter for a fracture affecting the growth plate at the upper end of the radius, where the bone has healed in an abnormal alignment (malunion). This indicates a previous injury to the radial physis that has not healed correctly, leading to functional or anatomical compromise.

Use this code when a patient presents for evaluation or treatment of a previously diagnosed physeal fracture of the proximal radius that has healed with malunion. This applies to subsequent visits after the initial treatment, such as for physical therapy, follow-up imaging, or discussion of corrective surgery.

• Ensure documentation clearly states "malunion" and specifies the "upper end of radius" and "physeal fracture."
• Verify this is a subsequent encounter, not the initial treatment or a nonunion.
• Laterality is unspecified, so use this code when the medical record does not specify left or right arm.
