Poisn by oth parasympath and spasmolytics, self-harm, init

This code signifies a deliberate act of self-harm involving an overdose or misuse of medications that block the parasympathetic nervous system, such as anticholinergics or antispasmodics. Patients may present with symptoms like dry mouth, blurred vision, urinary retention, confusion, or tachycardia due to the drug's effects. This diagnosis indicates the initial phase of treatment for such an event.

Apply this code when a patient is admitted or first seen for an intentional self-poisoning with anticholinergic or antispasmodic drugs. This includes situations where the patient explicitly states intent to harm themselves, or when clinical evidence strongly suggests self-inflicted poisoning. It is used for the initial assessment and management of the acute toxic effects.

• Ensure documentation clearly specifies "intentional self-harm" as the mechanism of poisoning.
• Confirm the specific drug class (anticholinergic/antispasmodic) is identified in the medical record.
• This "A" seventh character indicates an initial encounter for active treatment of the poisoning.
