ICD-10-CMSalter-Harris Type II physeal fracture of lower end of right fibula, subsequent encounter for fracture with malunion
This code signifies a Salter-Harris Type II fracture affecting the growth plate at the lower end of the right fibula, where the fracture has healed in an imperfect alignment. This specific type of physeal fracture involves a break through the growth plate and extending into the metaphysis, but not into the epiphysis. The "malunion" indicates that the bone has mended, but with an unacceptable degree of angulation, rotation, or shortening.
This code is appropriate for documenting follow-up care for a patient who previously sustained this specific fracture and is now presenting with complications related to its improper healing. It should be used when the physician is actively managing the malunion, such as during evaluations for corrective surgery, physical therapy to address functional deficits, or monitoring for long-term complications.
