Sltr-haris Type IV physl fx upper end humer, unsp arm, init

This code signifies a specific type of growth plate fracture (Salter-Harris Type IV) affecting the top portion of the humerus, the long bone of the upper arm. This fracture extends through the growth plate, metaphysis, and epiphysis, indicating a more complex injury to the developing bone.

Apply this code for initial encounters involving a closed Salter-Harris Type IV fracture of the proximal humerus, where the specific arm (left or right) is not documented. This is typically seen in pediatric patients following trauma to the shoulder or upper arm.

• Ensure documentation explicitly states "Salter-Harris Type IV" and "physeal fracture of upper end of humerus."
• Only use this code when the laterality (left or right arm) is truly unspecified in the medical record.
• Confirm the encounter is for the initial treatment of a closed fracture. Subsequent encounters or open fractures require different codes.
