Oth physl fx upper end unsp fibula, subs for fx w nonunion

This code signifies a fracture affecting the growth plate (physis) at the top of the fibula, where the bone has failed to heal properly after an initial injury. The patient is presenting for follow-up care related to this ongoing nonunion.

Apply this code when a patient is seen for continued management of a previously diagnosed physeal fracture of the proximal fibula that has not united. This includes situations where surgical intervention for nonunion is being planned or performed, or when conservative management for the nonunion is ongoing.

• Requires a seventh character of "K" for subsequent encounter with nonunion.
• Ensure documentation clearly states the fracture is of the physis and located at the upper end of the fibula.
• Do not use for initial encounters or for fractures that have healed.
