Toxic effect of benzene, undetermined, initial encounter

This code signifies a harmful reaction to benzene exposure where the intent (e.g., accidental, intentional self-harm, assault) is not documented or cannot be determined. The patient is in the acute phase of treatment for the toxic effects.

Apply this code when a patient presents with symptoms of benzene poisoning, and the medical record clearly indicates the exposure but lacks information regarding the circumstances or intent. This is appropriate for the initial visit or encounter for this specific toxic event.

• Ensure documentation explicitly states "undetermined" intent or provides no information regarding intent.
• Do not use if intent (e.g., accidental, intentional self-harm) is clearly documented; use the appropriate specific intent code instead.
• The 7th character "A" indicates an initial encounter for this condition.
