Sltr-haris Type I physl fx lower end of ulna, left arm, init

This code signifies a growth plate fracture at the distal end of the left ulna, specifically a Salter-Harris Type I injury. This type of fracture involves a separation of the epiphysis from the metaphysis through the physis (growth plate) without bone involvement, making it a relatively stable injury.

Apply this code for initial encounters involving a closed Salter-Harris Type I fracture of the growth plate at the lower end of the left ulna. This typically occurs in pediatric patients due to trauma, such as a fall onto an outstretched hand.

• Ensure the documentation specifies "initial encounter" for a closed fracture.
• Verify the fracture is explicitly identified as Salter-Harris Type I and located at the distal ulna on the left side.
• Distinguish from other Salter-Harris types (II, III, IV, V) which have different code assignments.
