ICD-10: T40.995

The ICD-10-CM code T40.995 refers to the "Adverse effect of other psychodysleptics [hallucinogens]." This code is part of the broader classification of drug-related conditions and is specifically used to document adverse effects resulting from the use of hallucinogenic substances that are not classified under more specific categories.

Clinical Description

Definition

The term "psychodysleptics" encompasses a range of substances that alter perception, mood, and cognitive processes. Hallucinogens, a subset of psychodysleptics, can induce significant changes in sensory perception, thought processes, and emotional states. Common examples include substances like LSD (lysergic acid diethylamide), psilocybin (found in certain mushrooms), and mescaline (derived from peyote).

Adverse Effects

The adverse effects associated with hallucinogens can vary widely and may include:

• Psychological Effects: These can range from mild anxiety and confusion to severe hallucinations, paranoia, and psychosis. Users may experience altered states of consciousness that can lead to distressing experiences.
• Physiological Effects: Hallucinogens can also cause physical symptoms such as increased heart rate, elevated blood pressure, nausea, and dizziness. In some cases, they may lead to more severe medical complications.
• Long-term Effects: Some individuals may experience persistent changes in perception or mood, often referred to as Hallucinogen Persisting Perception Disorder (HPPD), which can be distressing and disruptive to daily life.

Clinical Considerations

When documenting an adverse effect using T40.995, healthcare providers should consider the following:

• Patient History: A thorough assessment of the patient's substance use history is essential. This includes identifying the specific hallucinogen used, the dosage, and the context of use (e.g., recreational, therapeutic).
