ICD-10-CMSalter-Harris Type I physeal fracture of right metatarsal, subsequent encounter for fracture with nonunion
This code signifies a Salter-Harris Type I fracture affecting the growth plate (physis) of a metatarsal bone in the right foot. The "Type I" indicates a complete separation of the epiphysis from the metaphysis without bone fracture. The "nonunion" aspect specifies that the fracture has failed to heal completely after the initial treatment, and the patient is presenting for ongoing care related to this complication.
Use this code for follow-up encounters where a patient is being treated for a previously diagnosed Salter-Harris Type I physeal fracture of the right metatarsal that has not healed. This includes situations where the patient is undergoing further evaluation, conservative management, or surgical intervention for the nonunion.
