Oth physeal fx upper end of l tibia, subs for fx w nonunion

This code signifies a fracture of the growth plate (physis) at the top portion of the left shin bone, excluding Salter-Harris types I and II. Importantly, it indicates that the fracture has failed to heal properly, resulting in a nonunion, and the patient is presenting for follow-up care or treatment related to this ongoing issue.

Apply this code when documenting a patient's subsequent visit for a non-healing physeal fracture of the proximal left tibia that is not classified as Salter-Harris type I or II. This would include scenarios where the patient is undergoing continued management, evaluation, or treatment for the established nonunion.

• Ensure documentation clearly specifies "nonunion" and "subsequent encounter" for accurate code assignment.
• Verify the fracture location is the "upper end of the left tibia" and not a Salter-Harris type I or II.
• Always review the full encounter documentation to confirm the patient's status (initial, subsequent, sequela) and the specific nature of the fracture.
