Sltr-haris Type III physl fx lower end rad, unsp arm, init

This code signifies a specific type of growth plate fracture (Salter-Harris Type III) affecting the lower end of the radius bone, which is one of the two long bones in the forearm. This particular fracture involves a break through the growth plate and extends into the epiphysis (the end of the bone), but the fracture is not open to the outside environment.

Use this code for initial encounters when a patient presents with a closed Salter-Harris Type III fracture of the distal radius, and the laterality (left or right arm) is not documented. This is common in pediatric patients who have sustained a fall or direct trauma to the wrist.

• Ensure the documentation explicitly states "Salter-Harris Type III" and "closed fracture."
• Only use this code for the initial treatment of the fracture; subsequent encounters will require a different seventh character.
• Avoid this code if the laterality of the arm is specified; instead, select the appropriate code for the left or right arm.
