Poisoning by other parasympathomimetics, assault, sequela

This code signifies a long-term complication or condition resulting from an intentional overdose or poisoning by parasympathomimetic (cholinergic) medications, where the poisoning was inflicted by another person. These agents stimulate the parasympathetic nervous system, and an overdose can lead to severe cholinergic crisis symptoms affecting multiple organ systems. The 'sequela' aspect indicates that the current patient encounter is for a residual effect of that past assault.

Use this code when documenting a patient presenting with a chronic or residual health problem directly attributable to a past assault involving poisoning by a cholinergic drug. This applies to follow-up care for conditions like persistent neurological damage, chronic respiratory issues, or other long-term organ dysfunction that developed as a consequence of the initial poisoning. It should not be used for the initial acute poisoning event.

• Always assign an additional code(s) to specify the nature of the sequela (e.g., specific neurological deficit, organ damage).
• Ensure documentation clearly links the current condition to a past assault by parasympathomimetics.
• Do not use this code for accidental or self-inflicted poisonings; different codes exist for those circumstances.
