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

This code signifies a fracture of the growth plate (physis) at the lower end of the right humerus, which is not healing properly (nonunion). This specific encounter is for ongoing management of this unhealed fracture after the initial treatment.

Use this code when a patient presents for follow-up care, evaluation, or treatment of a right distal humeral physeal fracture that has failed to unite. This applies to situations where the fracture is clearly documented as a nonunion, and the patient is past the initial acute phase of injury.

• Ensure documentation clearly states "nonunion" for the right distal humeral physeal fracture.
• Verify that the encounter is for subsequent care, not the initial treatment of the fracture.
• Always code laterality (right arm) accurately as specified.
