ICD-10-CMSalter-Harris Type II physeal fracture of unspecified metatarsal, initial encounter for open fracture
This code signifies an open Salter-Harris Type II fracture affecting the growth plate of an unspecified metatarsal bone in the foot. This type of fracture involves a break through the physis and extends into the metaphysis, with the skin and soft tissues also compromised, exposing the bone.
This code is appropriate for the initial treatment of a pediatric patient presenting with an open Salter-Harris Type II fracture of any metatarsal. It should be used when the specific metatarsal involved (e.g., first, second, third) is not documented.
