Crushing injury of larynx and trachea, initial encounter

This code signifies a severe traumatic compression injury affecting both the voice box (larynx) and the windpipe (trachea). Such an injury typically results from significant external force, leading to potential airway compromise, vocal cord damage, and structural integrity issues of these vital respiratory structures.

Apply this code for the initial treatment of patients presenting with a crushing injury to the larynx and trachea, often due to blunt force trauma like a direct blow to the neck or a motor vehicle accident. Documentation should clearly state the mechanism of injury, the specific anatomical structures involved (larynx and trachea), and that this is the first encounter for this specific injury.

• Ensure documentation specifies both laryngeal and tracheal involvement; if only one is injured, a more specific code should be used.
• This "A" suffix indicates an initial encounter for active treatment of the injury. Subsequent care would require a different seventh character.
• Consider external cause codes (V, W, X, Y categories) to fully describe the circumstances of the injury.
