ICD-10-CMSalter-Harris Type III physeal fracture of phalanx of left toe, subsequent encounter for fracture with malunion
This code signifies a specific type of growth plate fracture (Salter-Harris Type III) affecting a toe bone on the left foot. The fracture has previously occurred and is now being treated for improper healing, specifically malunion. This indicates that the bone segments have healed in an unsatisfactory position.
Apply this code when documenting follow-up care for a patient with a left toe phalanx Salter-Harris Type III fracture that has healed incorrectly, resulting in a deformity or functional impairment. This would be used during subsequent visits after the initial treatment, where the malunion is the primary focus of the encounter.
