ICD-10-CMSalter-Harris Type I physeal fracture of left metatarsal, subsequent encounter for fracture with nonunion
This code signifies a Salter-Harris Type I growth plate fracture affecting a metatarsal bone in the left foot. It specifically indicates that the patient is in a subsequent phase of care for this fracture, and a nonunion complication has developed, meaning the bone fragments are failing to heal together.
Use this code for follow-up encounters where a patient with a previously diagnosed left metatarsal Salter-Harris Type I fracture is being treated for the ongoing issue of nonunion. This would apply during clinic visits, imaging studies, or surgical interventions aimed at addressing the failed healing process.
