ICD-10-CMSalter-Harris Type I physeal fracture of lower end of left tibia, 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 left tibia, which is currently undergoing treatment for malunion. A Type I fracture involves a complete separation of the epiphysis from the metaphysis through the physis, without bone breakage. Malunion indicates that the fracture has healed, but in an unsatisfactory position, leading to anatomical or functional impairment.
This code is appropriate for documenting follow-up care for a patient whose initial Salter-Harris Type I fracture of the left distal tibia has healed incorrectly. It should be used when the physician is actively managing the complications arising from this malunion, such as planning for corrective surgery, monitoring for further complications, or assessing functional limitations. This code is specifically for subsequent encounters, not the initial treatment of the acute fracture.
