Displ spiral fx shaft of humerus, left arm, init for opn fx

This code signifies a fracture occurring in a spiral pattern along the shaft of the left humerus, where the bone fragments are no longer in their normal anatomical alignment. It specifically indicates an open fracture, meaning the skin and soft tissue have been compromised, exposing the bone. This is the initial encounter for treatment of this injury.

Apply this code for a patient presenting with a newly diagnosed, displaced spiral fracture of the diaphysis of the left humerus that has broken through the skin. This would be used when the patient is receiving active treatment for the fracture, such as surgical repair or initial casting/immobilization.

• Ensure documentation clearly specifies "displaced" and "spiral" fracture morphology of the humeral shaft.
• Confirm the laterality is "left arm" and that the fracture is explicitly documented as "open."
• Verify this is the patient's first encounter for active treatment of this specific fracture to use the "B" seventh character.
