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

This code describes a follow-up encounter for a right upper humerus fracture that occurred through the growth plate (physis), and has healed in an unsatisfactory position, resulting in a malunion. This indicates a previous injury to the growth plate region of the humerus on the right side, which has now consolidated but with an anatomical deformity.

Use this code for subsequent visits where a patient is being managed for a malunited physeal fracture of the right proximal humerus. This typically applies to orthopedic follow-ups, physical therapy, or surgical planning for corrective osteotomy due to the malunion. It signifies that the fracture is no longer acute but has healed improperly.

• Ensure documentation clearly states "malunion" and specifies the right upper humerus and physeal involvement.
• This code is for subsequent encounters; an initial encounter would use a different seventh character.
• Distinguish from nonunion, which implies a failure to heal, rather than healing in a deformed position.
