ICD-10-CMSalter-Harris Type I physeal fracture of right metatarsal, initial encounter for open fracture
This code signifies a Salter-Harris Type I fracture affecting the growth plate (physis) of a metatarsal bone in the right foot. This specific type of physeal fracture involves a complete separation of the epiphysis from the metaphysis through the growth plate, without any bone breakage. The "open fracture" designation indicates that the skin and soft tissues overlying the fracture site have been compromised, exposing the bone to the external environment.
Use this code for the initial encounter of a patient presenting with a Salter-Harris Type I fracture of a right metatarsal, where there is an open wound communicating with the fracture. This typically occurs due to high-energy trauma, such as a crush injury or direct impact, resulting in both the growth plate injury and a break in the skin.
