Sltr-haris Type I physl fx low end ulna, l arm, 7thK

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

Apply this code when documenting follow-up care for a patient with a previously diagnosed Salter-Harris Type I fracture of the distal left ulnar physis that has not united. This would be used during clinic visits, imaging reviews, or surgical planning for interventions addressing the nonunion. It is appropriate for situations where the fracture healing process has stalled or failed.

• Ensure documentation clearly specifies "left arm" and "nonunion" for accurate code assignment.
• Verify that the encounter is indeed "subsequent" and not the initial treatment for the fracture.
• Distinguish between delayed union and nonunion; this code specifically applies to nonunion.
