Displaced segmental fx shaft of humerus, unsp arm, init

This code signifies a fracture occurring in the middle portion (shaft) of the humerus bone, where the bone is broken into at least three pieces (segmental) and the bone fragments are no longer in their normal alignment (displaced). This specific code is used when the affected arm is not specified (e.g., right or left) and the skin over the fracture remains intact (closed fracture), representing the initial treatment for the injury.

Apply this code for a patient presenting with a newly diagnosed, non-specific arm humerus shaft fracture that is both segmental and displaced, and the skin is not broken. This is appropriate for the initial visit where the fracture is first evaluated and treatment plans are initiated, such as reduction or casting.

• Ensure documentation clearly states "segmental" and "displaced" for the humerus shaft.
• Only use this code when the laterality (right or left arm) is not documented. If laterality is known, a more specific code should be chosen.
• The "A" suffix indicates an initial encounter for active treatment of the fracture. Subsequent encounters will require different seventh characters.
