Burn of larynx, trachea, and lung

This code represents thermal injury to the upper and lower respiratory tracts, specifically involving the larynx, trachea, and lung tissue. It describes damage caused by heat, steam, or hot gases inhaled into the respiratory system, leading to inflammation, edema, and potential airway compromise.

This code is appropriate for patients presenting with respiratory distress, stridor, hoarseness, or cough following exposure to smoke, fire, or superheated air. Documentation should clearly indicate thermal injury to the respiratory tract, often noted during bronchoscopy or direct visualization, and specify involvement of the larynx, trachea, and/or lungs.

• Always code the external cause of the burn (E-code) in addition to this diagnosis.
• Distinguish from chemical burns of the respiratory tract, which are coded differently.
• Consider additional codes for associated complications such as respiratory failure or pneumonia.
