Oth disp fx of upper end of unsp humerus, init for opn fx

This code signifies a fracture in the upper portion of the humerus (the bone of the upper arm) that is not a surgical neck, anatomical neck, or greater tuberosity fracture, and has shifted out of its normal alignment. It specifically indicates an open fracture, meaning the skin and soft tissue have been compromised, exposing the bone. This code is used for the initial treatment of such an injury.

Use this code when documenting the initial encounter for a patient presenting with an open fracture of the proximal humerus that is not otherwise specified as a surgical neck, anatomical neck, or greater tuberosity fracture. This would include comminuted, segmental, or other complex fractures of the upper humerus that have broken through the skin.

• Ensure documentation clearly specifies "open fracture" and "initial encounter."
• Verify the fracture location is in the upper humerus but does not fit more specific codes (e.g., surgical neck, anatomical neck, greater tuberosity).
• Later encounters for this specific fracture will require a different seventh character (e.g., D for subsequent, S for sequela).
