Oth physeal fx lower end of r fibula, subs for fx w nonunion

This code signifies a fracture of the growth plate (physis) at the lower end of the right fibula, which is not a Salter-Harris type I or II fracture. Importantly, this specific encounter is for a fracture that has failed to heal properly (nonunion) after initial treatment.

Apply this code when a patient presents for follow-up care of a previously diagnosed physeal fracture of the distal right fibula, and imaging or clinical assessment confirms that the fracture fragments have not united. This is used for subsequent visits related to the ongoing management of the nonunion, such as for evaluation of treatment options or monitoring progress.

• Ensure documentation clearly specifies "nonunion" and "subsequent encounter" for the right fibula's lower physeal fracture.
• Verify the fracture is not a Salter-Harris type I or II, as those have specific codes.
• Do not use for initial treatment or routine follow-up of a healing fracture; reserve for documented nonunion.
