Toxic effect of petroleum products, undetermined, init

This code signifies a patient presenting with adverse health effects due to exposure to petroleum products, where the intent of the exposure (e.g., accidental, intentional self-harm, assault) cannot be determined. The "initial encounter" designation indicates that the patient is receiving active treatment for the toxic effect.

Apply this code when a patient exhibits symptoms of petroleum product toxicity, and documentation clearly states that the circumstances surrounding the exposure are unknown or undetermined. This is appropriate for the first visit where the patient is being evaluated and treated for the acute effects of the poisoning.

• Always sequence this code first when it represents the primary reason for the encounter.
• Do not use this code if the intent of the exposure (e.g., accidental, intentional) is documented; instead, select the appropriate intent character.
• Ensure documentation supports "undetermined" intent and "initial encounter" for accurate code assignment.
