ICD-10-CMSalter-Harris Type II physeal fracture of unspecified calcaneus, initial encounter for open fracture
This code signifies a fracture affecting the growth plate (physis) of the heel bone (calcaneus) in a child or adolescent, specifically a Salter-Harris Type II injury. This type of fracture involves a break through the physis and extending into the metaphysis (the shaft of the bone adjacent to the growth plate), but not into the epiphysis (the end of the bone). The fracture is open, meaning there is a break in the skin communicating with the fracture site.
This code is appropriate for the initial treatment encounter of an open Salter-Harris Type II fracture of the calcaneus, where the specific side (left or right) of the calcaneus is not documented. This typically occurs following trauma, such as a fall or direct impact to the heel, in skeletally immature individuals.
