ICD-10-CMSalter-Harris Type II physeal fracture of lower end of right femur, subsequent encounter for fracture with malunion
This code signifies a specific growth plate fracture in the lower part of the right thigh bone (femur) that has been previously treated but is now healing improperly (malunion). It's a Salter-Harris Type II fracture, meaning the fracture line extends through the growth plate and into the metaphysis (the wider part of the bone shaft adjacent to the growth plate).
This code is used when a patient presents for follow-up care of a previously diagnosed Salter-Harris Type II physeal fracture of the lower right femur, and clinical or radiological assessment confirms that the fracture is healing with a deformity or misalignment. This typically occurs during subsequent visits after the initial treatment, such as cast changes, physical therapy, or surgical planning for corrective procedures.
