ICD-10-CMSalter-Harris Type I physeal fracture of lower end of right fibula, initial encounter for closed fracture
This diagnosis code signifies a growth plate fracture at the distal end of the right fibula, specifically a Salter-Harris Type I injury. This type of fracture involves a separation of the epiphysis from the metaphysis through the physis (growth plate) without bone breakage, making it a relatively stable injury.
This code is appropriate for initial encounters where a patient presents with a newly diagnosed, closed Salter-Harris Type I fracture of the lower right fibula. This typically occurs in pediatric or adolescent patients following trauma to the ankle region.
