Poisoning by psychodysleptics (hallucinogens)

This code signifies an adverse health effect resulting from the ingestion, inhalation, or absorption of hallucinogenic substances. It encompasses both accidental and intentional exposures leading to toxic effects on the body, particularly affecting perception, thought, and mood. The poisoning can manifest with a range of symptoms, from mild perceptual distortions to severe psychosis or physiological compromise.

Assign this code when documentation clearly indicates a patient presenting with signs and symptoms of poisoning specifically due to hallucinogens, such as LSD, psilocybin, mescaline, or PCP. This applies to acute intoxication cases requiring medical intervention. Supporting documentation should detail the substance involved (if known), the patient's clinical presentation, and the causal link to the hallucinogen.

• Always code the specific hallucinogen if known and documented, using an E-code for external cause of poisoning.
• Distinguish between poisoning (toxic effect) and adverse effect (properly administered drug).
• Do not use for drug abuse or dependence without evidence of acute poisoning.
