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

This code signifies a growth plate fracture at the lower end of the right humerus, specifically a Salter-Harris Type I, which involves a complete separation of the epiphysis from the metaphysis without bone fracture. The "subsequent encounter" indicates ongoing treatment for this fracture, and "nonunion" specifies that the bone fragments have failed to heal together after a reasonable period.

Apply this code when documenting follow-up care for a patient whose initial Salter-Harris Type I fracture of the distal right humerus has not healed. This includes scenarios where surgical intervention for nonunion is being planned or has been performed, or when conservative management for nonunion is ongoing. It is used after the initial treatment phase for the acute fracture.

• Ensure documentation clearly states "nonunion" and specifies the right arm and lower end of the humerus.
• Verify the encounter is for follow-up care, not the initial treatment of the acute fracture.
• Distinguish from malunion, which implies healing in an unsatisfactory position, whereas nonunion indicates no healing has occurred.
