Sltr-haris Type IV physl fx lower end radius, unsp arm, init

This code signifies a fracture that extends through the growth plate, metaphysis, and epiphysis at the distal end of the radius. It is a severe type of growth plate injury, indicating damage to all three components of the bone's growth center. The fracture is closed, meaning the skin remains intact, and the specific arm affected is not documented.

Use this code for initial encounters involving a pediatric patient presenting with a Salter-Harris Type IV fracture of the distal radius, where the medical record does not specify whether it's the left or right arm. This typically occurs following a fall onto an outstretched hand or other direct trauma to the wrist.

• Ensure documentation clearly states "Salter-Harris Type IV" and "distal radius."
• Verify the encounter is "initial" for a closed fracture; subsequent encounters or open fractures require different codes.
• Only use the "unspecified arm" designation if the medical record genuinely lacks laterality.
