Sltr-haris Type IV physeal fracture of left metatarsal, 7thK

This code signifies a complex growth plate fracture (Salter-Harris Type IV) affecting the left metatarsal bone in a pediatric patient. This specific type of fracture involves both the growth plate and a portion of the metaphysis and epiphysis. The "subsequent encounter for fracture with nonunion" indicates that the fracture has failed to heal properly and the patient is receiving ongoing care for this complication.

Use this code for follow-up visits or admissions where a pediatric patient is being treated for a previously diagnosed Salter-Harris Type IV fracture of the left metatarsal that has not united. This includes scenarios such as surgical intervention for nonunion, casting changes, or evaluation of nonunion progression.

• Always sequence this code as a secondary diagnosis if the primary reason for the encounter is treatment of the nonunion (e.g., surgical procedure code).
• Ensure documentation clearly specifies "left metatarsal" and "Salter-Harris Type IV" to support this code.
• Verify that the encounter is indeed "subsequent" and that nonunion is explicitly documented.
