Ignition of highly inflammable material

This code signifies an external cause of injury or poisoning resulting from the ignition of materials that are easily combustible. This includes incidents where highly flammable substances, such as gasoline, propane, or certain chemicals, ignite, leading to burns, smoke inhalation, or other related injuries. It describes the mechanism of injury rather than the specific injury itself.

Use this code when documentation clearly indicates that a patient's injury or condition was caused by the ignition of a highly flammable material. This typically applies to burn injuries, respiratory conditions from smoke, or other trauma directly resulting from such an event. Documentation should specify the involvement of a highly flammable substance and its ignition as the cause.

• Always sequence this external cause code after the primary diagnosis describing the nature of the injury (e.g., burn, smoke inhalation).
• Distinguish from codes for explosions (E923.x) or other types of fires not involving highly inflammable materials.
• Ensure documentation specifies "ignition" of a "highly inflammable material" to support accurate code assignment.
