Displaced spiral fx shaft of humerus, unsp arm, init

This code signifies a fracture occurring in the mid-section (shaft) of the humerus bone, which is the long bone of the upper arm. The fracture pattern is spiral, meaning it twists around the bone, and the bone fragments are displaced from their normal alignment. The specific arm (left or right) is not documented.

Apply this code for a patient presenting with an acute, newly diagnosed spiral fracture of the humeral shaft where the fracture fragments are clearly displaced, and the medical record does not specify laterality. This code is appropriate for the initial treatment of a closed fracture, meaning the skin over the fracture site is intact.

• Ensure documentation explicitly states "spiral fracture" and "displaced" for the humeral shaft.
• Only use this code when the arm laterality (left or right) is truly unspecified in the medical record. If laterality is known, a more specific code should be chosen.
• The "A" seventh character indicates an initial encounter for active treatment of the fracture.
