ICD-10-CMSalter-Harris Type IV physeal fracture of right metatarsal, subsequent encounter for fracture with malunion
This code signifies a Salter-Harris Type IV fracture affecting the growth plate and epiphysis/metaphysis of a metatarsal bone in the right foot. The "malunion" indicates that the fracture has healed, but in an unsatisfactory position, leading to deformity or functional impairment. The "subsequent encounter" specifies that this code is used for follow-up care after the initial treatment of the fracture.
This code is appropriate for documenting ongoing management of a right metatarsal Salter-Harris Type IV fracture that has healed with malunion. This includes scenarios where the patient is presenting for evaluation of persistent pain, functional limitations, or consideration of corrective osteotomy due to the malunion. It would also be used for monitoring the long-term effects of the malunion.
