Closed fracture of larynx and trachea

This code signifies a fracture of the laryngeal or tracheal cartilages where the skin and mucous membranes remain intact. Such injuries often result from blunt force trauma to the neck, potentially leading to airway compromise, voice changes, or difficulty swallowing.

Apply this code when documentation explicitly states a closed fracture of the larynx or trachea, typically following direct trauma. Supporting documentation should include imaging reports (e.g., CT scan) confirming the fracture and a physician's assessment detailing the closed nature of the injury.

• Differentiate from open fractures, which involve a break in the skin or mucous membrane communicating with the fracture site.
• Ensure the documentation specifies which structure (larynx or trachea) is fractured, as this code covers both.
• Consider sequencing this code as the primary diagnosis if the fracture is the main reason for the encounter.
