Poisoning by ganglion-blocking agents

This code signifies an adverse reaction or overdose specifically due to medications that block nerve impulses in autonomic ganglia. These agents are typically used to lower blood pressure in specific medical contexts, and their poisoning can lead to severe cardiovascular and neurological effects.

Apply this code when documentation clearly indicates a patient's condition is a direct result of an overdose, accidental poisoning, or adverse effect from a ganglion-blocking agent. This includes scenarios where the drug was taken incorrectly, prescribed inappropriately, or ingested accidentally.

• Always sequence this code as a secondary diagnosis following the manifestation of the poisoning (e.g., hypotension, bradycardia).
• Ensure documentation specifies the drug class as a ganglion-blocking agent; avoid using for other antihypertensives.
• Consider an E-code (E850-E869) to identify the specific drug and intent of the poisoning.
