ICD-10-CMSalter-Harris Type III physeal fracture of unspecified metatarsal, initial encounter for closed fracture
This code signifies a fracture involving the growth plate (physis) and extending into the joint surface of an unidentifiable metatarsal bone in the foot. It's a specific type of Salter-Harris fracture (Type III), indicating a break through the physis and epiphysis. This particular code is used for the initial treatment of a closed fracture, meaning the skin remains intact over the injury.
This code is appropriate for the initial encounter when a pediatric patient presents with a Salter-Harris Type III fracture of a metatarsal, and the specific metatarsal involved is not documented. It applies when the fracture is closed and the patient is receiving their first treatment for this injury.
