Primary blast injury of lung, bilateral, initial encounter

This code signifies damage to both lungs resulting from the direct impact of a blast wave. This injury is typically characterized by pulmonary contusions, hemorrhage, and/or air embolism, occurring immediately at the time of the explosive event.

Apply this code for patients presenting with acute, bilateral lung injuries directly attributable to a blast exposure, such as from an explosion or improvised explosive device. This code is appropriate for the initial assessment and treatment phase of such an injury.

• Ensure documentation clearly states the injury is bilateral and directly caused by a blast.
• Confirm this is the patient's first encounter for this specific injury.
• Do not use for secondary blast injuries or injuries from penetrating fragments.
