Toxic effect of tobacco cigarettes, assault, sequela

This code signifies the long-term or residual health problems resulting from a past poisoning by tobacco cigarettes, specifically when the exposure was due to an assault. It indicates that the patient is experiencing lasting effects from a non-accidental, intentional administration of tobacco cigarettes.

Apply this code when documenting chronic conditions or persistent symptoms directly attributable to a prior assault involving tobacco cigarette toxicity. This would include follow-up encounters for conditions like chronic respiratory issues, cardiovascular damage, or neurological sequelae that developed after the initial toxic event.

• Always ensure documentation clearly links the current sequela to a past assault involving tobacco cigarette toxicity.
• Do not use for acute toxic effects; this code is specifically for the lasting consequences.
• Requires a seventh character 'S' to indicate sequela, as this is a subsequent encounter for the long-term effects.
