Oth physl fx upper end humer, r arm, subs for fx w nonunion

This code signifies a follow-up encounter for a right upper arm growth plate fracture that is failing to heal properly. Specifically, it indicates a fracture of the humerus near the shoulder joint in a pediatric patient, where the bone fragments have not united after initial treatment.

Apply this code when documenting subsequent care for a pediatric patient with a previously diagnosed right proximal humeral physeal fracture that has progressed to nonunion. This would include evaluations, imaging, or interventions aimed at addressing the persistent lack of healing, such as surgical planning for revision or bone grafting.

• Ensure documentation clearly states "nonunion" and specifies the right upper extremity.
• Verify the encounter is for follow-up care, not the initial treatment of the fracture.
• Confirm the fracture involves the physis (growth plate) of the proximal humerus.
