ICD-10-CMSalter-Harris Type II physeal fracture of upper end of humerus, right arm, initial encounter for closed fracture
This code signifies a specific growth plate fracture in the upper part of the right arm bone (humerus) in a pediatric patient. It's a Salter-Harris Type II injury, meaning the fracture extends through the growth plate and into the metaphysis, but spares the epiphysis. This type of fracture is common in children and adolescents due to the relative weakness of the growth plate.
Use this code for the initial encounter when a patient presents with a newly diagnosed, closed Salter-Harris Type II fracture of the proximal humerus on the right side. This applies to cases where the skin remains intact over the fracture site. It is appropriate for the initial treatment phase, including reduction and casting, or surgical repair.
