ICD-10-CMSalter-Harris Type II physeal fracture of unspecified metatarsal, subsequent encounter for fracture with nonunion
This code signifies a specific type of growth plate fracture (Salter-Harris Type II) affecting an unknown metatarsal bone in the foot. The "subsequent encounter for fracture with nonunion" indicates that the patient is receiving ongoing care for this fracture, and it has failed to heal properly. This nonunion complicates the recovery and may require further intervention.
Use this code for follow-up visits where a patient is being treated for a previously diagnosed Salter-Harris Type II fracture of an unspecified metatarsal, and imaging or clinical assessment confirms that the fracture has not united. This includes scenarios where surgical intervention for nonunion is being planned or has recently been performed, or during conservative management of the nonunion.
