Poisn by centr-acting/adren-neurn-block agnt, assault, init

This code signifies a poisoning event resulting from centrally-acting or adrenergic-neuron-blocking agents, specifically when the poisoning is due to an assault. It indicates the patient is in the initial phase of treatment for this specific type of intentional harm.

Apply this code when a patient presents with symptoms of poisoning by medications like alpha- or beta-blockers, centrally-acting antihypertensives, or similar agents, and the medical record clearly documents the poisoning was an intentional act by another person. This code is appropriate for the initial encounter for treatment of the acute poisoning.

• Always sequence this code after the primary diagnosis for the specific adverse effect or symptom of the poisoning.
• Ensure documentation explicitly states "assault" as the intent; do not use for accidental or self-harm poisonings.
• Confirm the encounter is the "initial encounter" for treatment of the poisoning; subsequent encounters will use different seventh characters.
