Poisoning by oth parasympathomimetics, self-harm, subs

This diagnosis code signifies a poisoning event resulting from the deliberate self-administration of parasympathomimetic (cholinergic) medications. These drugs stimulate the parasympathetic nervous system, and an overdose can lead to severe systemic effects. This specific code is used for encounters following the initial treatment of the poisoning.

Apply this code for follow-up visits, rehabilitation, or ongoing management of complications arising from a self-inflicted overdose of cholinergic agents. This includes scenarios where the patient is being monitored for long-term effects, undergoing psychiatric evaluation, or receiving treatment for organ damage caused by the poisoning.

• Ensure documentation clearly states "intentional self-harm" and that the encounter is not the initial treatment.
• Always code any associated physical or mental health conditions resulting from the poisoning.
• Verify the specific substance involved is a parasympathomimetic/cholinergic agent to differentiate from other drug classes.
