F18.150 Inhalant abuse with inhalant-induced psychotic disorder with delusions

Name of the Condition

• Common Name: Inhalant Abuse with Inhalant-Induced Psychotic Disorder with Delusions
• Medical Term: Inhalant Abuse with Inhalant-Induced Psychotic Disorder with Delusions

Summary

Inhalant abuse with inhalant-induced psychotic disorder with delusions involves the intentional misuse of inhalants—substances that produce chemical vapors—to achieve psychoactive effects, accompanied by the development of psychotic symptoms, specifically delusions, directly attributable to inhalant use. This condition combines substance-related misuse with psychotic features, such as fixed false beliefs, and can lead to acute intoxication, dependence, and significant physical or psychological harm, impacting an individual's health and daily functioning.

Causes

Inhalant abuse is primarily driven by the repeated misuse of inhalants for their psychoactive effects. Inhalants are often everyday household or industrial products, such as glue, paint thinners, aerosols, or solvents. The misuse of these substances can lead to dependence and, in some cases, induce psychotic symptoms due to their neurotoxic effects on the central nervous system.

Risk Factors

• Adolescents and young adults are more likely to experiment with inhalants.
• Individuals with a history of substance abuse or mental health disorders.
• Accessibility to inhalant products.
• Lack of proper supervision or guidance.

Symptoms

• Intense cravings or compulsive inhalant use.
• Fixed false beliefs (delusions) unrelated to cultural or situational context.
• Coordination problems, dizziness, or lethargy.
• Unexplained behavioral changes such as aggression or mood swings.
• Cognitive impairment or memory issues.

Diagnosis

Clinical evaluation including a detailed history of inhalant use, physical examination, and assessment of symptoms. Laboratory tests may be used to detect inhalant exposure or related complications. Psychiatric evaluation is necessary to confirm psychotic symptoms and rule out other causes of delusions.

Treatment Options

Treatment typically involves discontinuing inhalant use, often with medical supervision to manage withdrawal. Psychotherapy, such as cognitive-behavioral therapy, may help address substance use and psychotic symptoms. In some cases, antipsychotic medications may be prescribed to manage delusions or other psychotic features. Supportive care, including monitoring for physical complications, is also important.

Prognosis and Follow-Up

Prognosis depends on the severity of use, presence of comorbid conditions, and adherence to treatment. Early intervention improves outcomes, but chronic use may lead to persistent cognitive or psychiatric issues. Regular follow-up with healthcare providers is essential to monitor recovery, manage symptoms, and prevent relapse.

Complications

• Persistent cognitive impairment or memory problems.
• Worsening of psychotic symptoms or development of chronic psychotic disorders.
• Physical complications, such as organ damage or neurological issues.
• Increased risk of accidents or injuries due to impaired judgment.

Lifestyle & Prevention

• Avoiding access to inhalant products, especially for at-risk individuals.
• Educating communities about the risks of inhalant misuse.
• Providing alternative coping strategies or support for stress or mental health concerns.
• Encouraging open communication about substance use within families or support networks.

When to Seek Professional Help

Seek immediate medical attention if experiencing severe symptoms, such as intense delusions, hallucinations, or signs of acute intoxication. Consult a healthcare provider for persistent substance use, worsening mental health symptoms, or if inhalant use is interfering with daily life.

Tips for Medical Coders

Document the presence of inhalant abuse and inhalant-induced psychotic disorder with delusions clearly in the medical record. Ensure the psychotic symptoms (delusions) are directly linked to inhalant use and not attributable to another medical or psychiatric condition. Code F18.150 is specific to this combination of substance use and psychotic features with delusions; verify documentation supports the diagnosis without referencing other codes.
