Unsp physl fx upper end of r fibula, subs for fx w malunion

This code signifies a previously sustained, unspecified fracture of the growth plate (physis) at the upper end of the right fibula, which has subsequently healed in an abnormal or misaligned position. The malunion indicates that the bone fragments have united, but with a deformity that may impact function or appearance.

This code is used when a patient presents for follow-up care, evaluation, or treatment related to a malunited physeal fracture of the proximal right fibula. It is appropriate for situations where the initial fracture has already healed, but with an unsatisfactory anatomical alignment. This includes scenarios such as ongoing pain, limited range of motion, or cosmetic concerns due to the malunion.

• Ensure documentation clearly states "malunion" and specifies the right fibula and upper end.
• Verify that this is a subsequent encounter, not the initial treatment for the fracture.
• Do not use this code if the fracture is still open or if there is a nonunion (failure to heal).
