Poisoning by ganglionic blocking drugs, self-harm, init

This code signifies an overdose or adverse reaction to ganglionic blocking agents, such as trimethaphan or mecamylamine, that was deliberately self-inflicted by the patient. These medications primarily affect the autonomic nervous system, and poisoning can lead to severe cardiovascular and gastrointestinal symptoms. The "initial encounter" indicates the patient is actively receiving treatment for the acute effects of the poisoning.

Apply this code when a patient presents to an emergency department or is admitted for acute management of a self-administered overdose of a ganglionic blocking drug. This includes situations where the patient explicitly states intent to harm themselves or when clinical evidence strongly suggests intentional self-poisoning. It is used for the initial phase of treatment.

• Always sequence this code first when it represents the primary reason for the encounter.
• Requires an additional code for the specific ganglionic blocking agent if known (e.g., from the T36-T50 drug poisoning categories).
• Do not use for accidental poisoning or adverse effects from therapeutic use; those require different codes.
