ICD-10-CMSalter-Harris Type III physeal fracture of right metatarsal, initial encounter for open fracture
This code signifies a fracture affecting the growth plate (physis) of a metatarsal bone in the right foot, specifically a Salter-Harris Type III injury. This type of fracture involves a break through the physis and epiphysis, extending into the joint. The "open fracture" designation indicates that the skin and soft tissue over the fracture site have been compromised, exposing the bone to the external environment.
This code is appropriate for the initial treatment of a patient presenting with a newly diagnosed Salter-Harris Type III fracture of a right metatarsal, where the fracture has broken through the skin. This would include scenarios such as a crush injury or a direct impact causing both the fracture and an open wound.
