S89.311P
ICD-10-CMSalter-Harris Type I physeal fracture of lower end of right fibula, subsequent encounter for fracture with malunion
This code signifies a Salter-Harris Type I fracture affecting the growth plate at the distal end of the right fibula, where the bone has healed in an abnormal alignment. This malunion indicates that the fracture fragments did not unite in their anatomical position, potentially leading to functional impairment or deformity.
This code is appropriate for follow-up encounters where a previously diagnosed Salter-Harris Type I fracture of the right distal fibula is being managed, and imaging or clinical assessment confirms a malunion. It should be used when the patient is receiving ongoing care for the complications or sequelae of the malunited fracture, not for the initial treatment of the acute fracture.
