ICD-10-CMSalter-Harris Type I physeal fracture of upper end of right fibula, subsequent encounter for fracture with nonunion
This code describes a specific type of growth plate fracture (Salter-Harris Type I) located at the top portion of the right fibula. It indicates that the patient is in a later stage of care for this fracture, and unfortunately, the bone fragments have failed to heal properly, resulting in a nonunion.
Apply this code for follow-up encounters where a patient with a previously diagnosed Salter-Harris Type I fracture of the proximal right fibula is being treated for a confirmed nonunion. This would be used after the initial treatment phase, when the fracture has not united as expected.
