Toxic effect of benzene, intentional self-harm, sequela

This code signifies a long-term health problem or complication arising from a previous act of self-poisoning with benzene. The patient is experiencing residual effects directly attributable to a past intentional overdose or exposure to benzene.

Apply this code when documenting chronic conditions, organ damage, neurological deficits, or other lasting sequelae that are a direct result of a prior intentional self-harm event involving benzene. This would be used in follow-up encounters after the acute phase of the poisoning has resolved.

• Always sequence this sequela code after the code for the specific residual condition being treated.
• Ensure documentation clearly links the current condition to a past intentional benzene self-harm event.
• Do not use for acute poisoning or initial treatment of the self-harm event; those require acute poisoning codes.
