Unsp physl fx lower end of l fibula, subs for fx w malunion

This code signifies a fracture of the growth plate at the distal end of the left fibula, where the bone has healed in an abnormal alignment. This particular code is used when the patient is presenting for follow-up care or treatment of this malunion, not for the initial injury.

Apply this code when a patient with a previously diagnosed, unspecified physeal fracture of the left distal fibula is seen for management of a malunion. This includes scenarios such as evaluation for corrective surgery, physical therapy for functional limitations due to the malunion, or monitoring of the healing process after malunion has been identified.

• Ensure documentation clearly states "malunion" and specifies the "subsequent encounter" for this condition.
• Verify the fracture is of the "physeal" (growth plate) type and located at the "lower end of the left fibula."
• Do not use this code for initial treatment of the fracture or for nonunion; specific codes exist for those scenarios.
