ICD-10-CMSalter-Harris Type IV physeal fracture of unspecified metatarsal, initial encounter for open fracture
This code signifies a severe growth plate fracture (Salter-Harris Type IV) affecting an unspecified metatarsal bone in the foot. This specific type of fracture involves both the growth plate and a portion of the metaphysis and epiphysis, indicating a complex injury with potential for growth disturbance. The "open fracture" designation means the skin and soft tissues are compromised, exposing the bone to the external environment.
Use this code for initial encounters when documenting an open Salter-Harris Type IV fracture of any metatarsal bone. This would apply to patients presenting with a traumatic foot injury where the growth plate is involved, and there is a visible wound communicating with the fracture site. It is crucial for the provider's documentation to clearly specify the Salter-Harris type and the open nature of the fracture.
