Poisoning by unspecified psychodysleptics, assault, sequela

This code signifies a long-term health problem or complication resulting from a past poisoning by an unspecified hallucinogenic substance. The original poisoning was intentionally inflicted by another person. The sequela could manifest as persistent neurological, psychological, or physiological issues.

Apply this code when documenting a current condition that is a direct consequence of a prior assaultive poisoning by an unknown hallucinogen, and the acute phase of the poisoning has resolved. This is appropriate for chronic effects, such as ongoing cognitive deficits, psychiatric disorders, or organ damage directly attributable to the past event.

• Always sequence this code after the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a past assaultive hallucinogen poisoning.
• Avoid using this code for acute poisoning events; it is exclusively for sequelae.
