Toxic effect of petroleum products

This code represents the adverse health effects resulting from exposure to and absorption of petroleum-based substances. This can include systemic toxicity or localized damage caused by ingestion, inhalation, or dermal contact with products such as gasoline, kerosene, or lubricating oils. The effects can range from mild irritation to severe organ damage or central nervous system depression.

Use this code when documentation clearly indicates a patient's signs and symptoms are directly attributable to the toxic effects of petroleum products. This applies to accidental ingestions, occupational exposures, or intentional poisonings. Supporting documentation should specify the petroleum product involved and the resulting clinical manifestations.

• Always code the specific manifestation of the toxicity first, if known, followed by this code as an external cause.
• Distinguish from chemical burns (941-949) if the primary injury is a burn rather than systemic toxicity.
• Ensure documentation specifies "petroleum products" to differentiate from other chemical toxicities.
