Poisoning by oth parasympathomimetics, assault, init encntr

This diagnosis code indicates a patient has suffered poisoning due to intentional harm by another person using parasympathomimetic (cholinergic) drugs, such as certain glaucoma medications, myasthenia gravis treatments, or nerve agents. The patient is in the initial phase of receiving active treatment for the toxic effects.

Use this code when documenting an emergency department visit or initial hospitalization for a patient presenting with symptoms like excessive salivation, lacrimation, urination, defecation, gastrointestinal upset, emesis (SLUDGE syndrome), bradycardia, or bronchospasm, confirmed to be caused by cholinergic poisoning inflicted by another individual. This applies to the first encounter for this specific poisoning event.

• Ensure documentation clearly states the poisoning was an assault, not accidental or self-harm.
• Verify the specific substance is identified as a parasympathomimetic/cholinergic agent.
• Confirm this is the initial encounter for treatment of this poisoning event; subsequent encounters will use different seventh characters.
