ICD-10-CMSalter-Harris Type II physeal fracture of left metatarsal, initial encounter for open fracture
This code signifies a specific growth plate fracture affecting the left metatarsal bone in a child or adolescent. It's a Salter-Harris Type II injury, meaning the fracture line extends through the growth plate and then exits into the metaphysis, leaving the epiphysis intact. The "open fracture" designation indicates a break in the skin, exposing the bone to the external environment.
Apply this code for initial encounters involving a pediatric patient presenting with a left metatarsal fracture that involves the growth plate and has an associated open wound. This typically occurs due to trauma, such as a crush injury or direct impact, where the skin integrity is compromised.
