ICD-10: F16.929

ICD-10 code F16.929 refers to "Hallucinogen use, unspecified with intoxication, unspecified." This code is part of the broader classification of substance use disorders, specifically focusing on hallucinogens, which are substances that alter perception, mood, and various cognitive processes.

Clinical Description

Definition

Hallucinogens are a class of drugs that can cause significant alterations in sensory perception, thought processes, and emotional states. Common hallucinogens include substances like LSD (lysergic acid diethylamide), psilocybin (found in certain mushrooms), and mescaline (derived from peyote). The term "unspecified" in this context indicates that the specific type of hallucinogen used is not documented or is unknown.

Intoxication Symptoms

Intoxication from hallucinogens can manifest in various ways, including:

• Visual and Auditory Hallucinations: Users may see or hear things that are not present.
• Altered Sense of Time and Space: Perception of time may be distorted, and spatial awareness can be affected.
• Mood Changes: Intoxication can lead to heightened emotions, ranging from euphoria to anxiety or paranoia.
• Physical Symptoms: These may include increased heart rate, dilated pupils, and changes in blood pressure.

Diagnostic Criteria

The diagnosis of hallucinogen use with intoxication typically requires evidence of recent use of a hallucinogen, along with the presence of significant impairment or distress in social, occupational, or other important areas of functioning. The unspecified nature of the code suggests that the clinician may not have detailed information about the specific hallucinogen involved or the exact nature of the intoxication.

Clinical Implications

Treatment Considerations

Management of hallucinogen intoxication often involves supportive care, as there are no specific antidotes for hallucinogen effects. Treatment may include:

• Monitoring: Continuous observation of the patient’s vital signs and mental status.
• Environment: Providing a calm and safe environment to help reduce anxiety and agitation.
• Psychological Support: Counseling or therapy may be beneficial, especially if the patient experiences distressing hallucinations or paranoia.

Importance of Accurate Coding

Accurate coding with F16.929 is crucial for healthcare providers to ensure appropriate treatment and for insurance purposes. It also aids in the collection of data for public health monitoring and research on substance use trends.
