Poisn by centr-acting/adren-neurn-block agnt, asslt, sequela

This code signifies a long-term health problem or condition that arose as a direct consequence of a poisoning event involving centrally-acting or adrenergic-neuron-blocking agents. The original poisoning was intentionally inflicted by another person. The sequela could manifest as chronic organ damage, neurological deficits, or persistent psychological issues.

Use this code when documenting a patient's current condition that is a residual effect of a past poisoning by centrally-acting or adrenergic-neuron-blocking agents, where the poisoning was determined to be an assault. This applies to follow-up encounters for chronic conditions directly linked to the initial toxic exposure. Do not use for the initial acute poisoning event.

• Always assign an additional code to specify the nature of the sequela (e.g., specific organ damage, neurological disorder).
• Ensure documentation clearly links the current condition to the past poisoning and specifies the assault intent.
• This "S" seventh character indicates sequela and should only be used for conditions that are residual effects of a healed injury or poisoning.
