Toxic effect of liquefied petroleum gases

This code signifies the adverse health effects resulting from exposure to or ingestion of liquefied petroleum gases (LPG), such as propane or butane. It covers systemic toxicity, respiratory compromise, or other organ damage caused by these substances.

Use this code when a patient presents with symptoms or conditions directly attributable to the toxic effects of LPG. Documentation should clearly indicate exposure to propane, butane, or similar liquefied petroleum gases and the resulting clinical manifestations. This includes accidental inhalation, intentional abuse, or occupational exposure.

• Always code the specific manifestation of the toxic effect first, if known (e.g., respiratory failure, cardiac arrhythmia), followed by this code as an external cause.
• Distinguish from burns caused by ignited LPG, which would be coded separately based on burn site and degree.
• Ensure documentation specifies "toxic effect" rather than just "exposure" if no adverse health outcome occurred.
