Toxic effect of benzene, intentional self-harm, subs encntr

This code signifies a patient presenting for follow-up care or treatment of adverse health effects resulting from the deliberate ingestion, inhalation, or exposure to benzene with the intent to self-harm. The patient is no longer in the acute phase of the poisoning but is seeking ongoing management for the toxic effects.

Use this code for subsequent encounters when a patient is being treated for complications or persistent symptoms stemming from a prior intentional self-poisoning with benzene. This includes follow-up appointments for organ damage, neurological sequelae, or psychological support related to the initial toxic exposure. Do not use for the initial treatment of the acute poisoning.

• Ensure documentation clearly states "intentional self-harm" and "subsequent encounter."
• Always code the underlying mental health condition (e.g., depression, suicidal ideation) as an additional diagnosis.
• Specify the manifestation of the toxic effect (e.g., acute myeloid leukemia, aplastic anemia) if applicable and documented.
