ICD-10-CMSalter-Harris Type III physeal fracture of unspecified metatarsal, initial encounter for open fracture
This code signifies a Salter-Harris Type III fracture affecting the growth plate of an unidentifiable metatarsal bone in the foot. This specific type of fracture involves a break through the physis and epiphysis, extending into the joint, and is documented as an open fracture.
Use this code for initial encounters when a patient presents with an open Salter-Harris Type III fracture of a metatarsal, and the specific metatarsal (e.g., first, second) is not documented. This typically occurs following trauma where the skin is broken, exposing the bone.
