ICD-10-CMSalter-Harris Type II physeal fracture of phalanx of right toe, subsequent encounter for fracture with malunion
This code signifies a specific growth plate fracture (Salter-Harris Type II) affecting a toe bone on the right foot. It indicates that the fracture is currently healing, but with an imperfect alignment of the bone fragments (malunion).
Apply this code when documenting follow-up care for a patient whose right toe phalanx fracture, initially classified as Salter-Harris Type II, is now showing signs of malunion during the healing process. This would be used for subsequent visits after the initial treatment, where the malunion is being addressed or monitored.
