ICD-10-CMSalter-Harris Type II physeal fracture of phalanx of unspecified toe, initial encounter for closed fracture
This code describes a specific growth plate fracture (Salter-Harris Type II) affecting a toe phalanx in a pediatric patient. A Type II fracture involves the physis and extends into the metaphysis, but spares the epiphysis. "Unspecified toe" indicates the exact digit is not documented.
This code is appropriate for initial encounters when a closed Salter-Harris Type II fracture of an unstated toe phalanx is diagnosed. This typically occurs after trauma to the foot in a child or adolescent, such as a crush injury or direct impact.
