Toxic effect of petroleum products, assault, sequela

This code signifies the long-term or residual effects resulting from a deliberate poisoning or exposure to petroleum products. These sequelae can manifest as chronic respiratory issues, neurological damage, skin conditions, or other persistent health problems that developed after the initial toxic event. The assault nature indicates the exposure was intentionally inflicted by another party.

Assign this code when documenting the lasting health consequences of a petroleum product poisoning that occurred as a result of an assault, and the acute phase of the poisoning has passed. This is appropriate for follow-up visits where the patient is being treated for chronic conditions directly attributable to the past toxic exposure. Do not use for the initial acute poisoning.

• Always sequence this code after the code(s) for the specific sequela being treated (e.g., chronic bronchitis, peripheral neuropathy).
• Ensure documentation clearly links the current condition to the past petroleum product assault.
• Verify that the encounter is for the sequela and not for the acute toxic effect, which would use an acute poisoning code.
