Oth physl fx lower end unsp fibula, subs for fx w malunion

This code signifies a fracture of the growth plate at the lower end of the fibula, where the bone has healed in an abnormal alignment. This particular code is used when the patient is receiving follow-up care for this malunion.

Apply this code for patients presenting for evaluation or treatment of a previously sustained fibular physeal fracture that has healed incorrectly. This includes scenarios such as physical therapy for gait abnormalities or surgical consultation for corrective osteotomy due to the malunion.

• Ensure documentation clearly states "malunion" and specifies the "lower end of the fibula."
• Verify this is a subsequent encounter for the fracture, not the initial treatment.
• Confirm the fracture is physeal (growth plate) and not a different type of fracture.
