ICD-10-CMSalter-Harris Type I physeal fracture of left metatarsal, initial encounter for open fracture
This code signifies a fracture affecting the growth plate (physis) of a metatarsal bone in the left foot, specifically classified as a Salter-Harris Type I. This type of fracture involves a complete separation of the epiphysis from the metaphysis through the physis, without bone involvement. The "open fracture" designation indicates a break in the skin, exposing the bone to the external environment.
This code is appropriate for the initial treatment of a patient presenting with a Salter-Harris Type I fracture of the left metatarsal, where the fracture has broken through the skin. This includes emergency department visits, initial orthopedic consultations, or the first surgical intervention for such an injury. It should be used when the patient is receiving active treatment for the fracture.
