Sltr-haris Type IV physl fx low end humer, r arm, 7thK

This code signifies a complex growth plate fracture at the distal end of the right humerus, specifically a Salter-Harris Type IV injury. This type of fracture involves both the epiphysis and metaphysis, extending through the physis. The "subsequent encounter with nonunion" indicates that the fracture has failed to heal properly after initial treatment and the patient is presenting for ongoing care related to this complication.

Use this code for follow-up visits where a patient is being managed for a previously diagnosed Salter-Harris Type IV fracture of the right distal humerus that has not united. This includes evaluations for surgical intervention, casting changes, or other treatments aimed at addressing the nonunion. It would not be used for the initial treatment of the fracture.

• Ensure documentation clearly specifies "nonunion" and not delayed union or malunion, as these have different codes.
• Verify the fracture location is the lower end of the humerus and laterality is the right arm.
• Confirm the encounter is subsequent to initial treatment, not the initial injury or a sequela.
