Blast and inhalation injuries in the chest are primarily coded to which organ?

Injuries resulting from blast and inhalation are primarily associated with the lungs due to their direct exposure to environmental factors and the impact of blast waves. The lungs are responsible for gas exchange and are highly sensitive to trauma, particularly from forces that can cause physical disruption or damage. Blast injuries can lead to barotrauma, pulmonary contusions, or even structural damage to lung tissue. Inhalation injuries, often caused by smoke, chemicals, or hot gases, can also severely affect lung function and result in conditions such as acute respiratory distress syndrome (ARDS).

While the heart, liver, and kidneys are vital organs that can be affected by trauma, they are not the primary focus when considering blast and inhalation injuries, which distinctly target the pulmonary system. Thus, coding these types of injuries to the lungs recognizes their central role in the pathophysiology of such traumatic events.
