ICD-10: F19.921

ICD-10 code F19.921 refers to a specific diagnosis within the broader category of psychoactive substance use disorders. This code is used to classify cases of other psychoactive substance use that are unspecified and associated with intoxication with delirium. Below is a detailed clinical description and relevant information regarding this diagnosis.

Clinical Description

Definition

The term "psychoactive substances" encompasses a wide range of drugs that can alter mood, perception, and cognitive function. These substances can include legal drugs (like alcohol and prescription medications) as well as illegal drugs (such as cocaine, heroin, and hallucinogens). The classification under F19.921 indicates that the specific substance causing the intoxication is not identified, which can complicate treatment and management.

Intoxication with Delirium

Intoxication refers to the physiological and psychological effects that occur after the consumption of a psychoactive substance. When intoxication is accompanied by delirium, it signifies a severe disturbance in mental abilities, leading to confusion, disorientation, and an inability to focus. Delirium can manifest as:

• Acute confusion: Sudden onset of confusion and inability to maintain attention.
• Altered consciousness: Fluctuations in awareness and responsiveness to the environment.
• Cognitive impairment: Difficulties with memory, language, and perception.

Delirium is often a medical emergency, requiring immediate attention, especially if it is related to substance use.

Diagnostic Criteria

To diagnose F19.921, clinicians typically consider the following criteria:

1. Substance Use: Evidence of use of a psychoactive substance that is not classified under other specific codes.
2. Intoxication Symptoms: Observable signs of intoxication, which may include altered mental status, mood changes, and physical symptoms such as tremors or sweating.
3. Delirium: The presence of delirium, characterized by disturbances in attention, awareness, and cognitive function, which can be assessed through clinical evaluation.

Treatment Considerations

Management of patients diagnosed with F19.921 involves several key components:

• Medical Evaluation: A thorough assessment to rule out other causes of delirium, such as infections or metabolic imbalances.
• Supportive Care: Ensuring the safety of the patient, providing hydration, and monitoring vital signs.
• Substance Withdrawal Management: If applicable, managing withdrawal symptoms as the substance is cleared from the body.
• Psychiatric Intervention: Addressing underlying substance use disorders through counseling, therapy, or rehabilitation programs.

Conclusion

ICD-10 code F19.921 is crucial for identifying cases of unspecified psychoactive substance use with associated intoxication and delirium. Understanding this diagnosis is essential for healthcare providers to ensure appropriate treatment and management strategies are implemented. Early recognition and intervention can significantly improve patient outcomes and reduce the risk of complications associated with substance use disorders.
