ICD-10-CMSalter-Harris Type II physeal fracture of upper end of radius, right arm, subsequent encounter for fracture with nonunion
This code signifies a specific type of growth plate fracture in the upper part of the right radius bone, where the fracture line extends through the physis and into the metaphysis. Importantly, this code is used when the fracture has not healed as expected and the patient is presenting for follow-up care related to this nonunion.
Apply this code for subsequent encounters when a patient with a previously diagnosed Salter-Harris Type II physeal fracture of the right proximal radius is being treated for a documented nonunion. This includes visits for monitoring the nonunion, planning further interventions, or managing complications related to the lack of healing.
