In which group psychoactive substance use disorders are included in the ICD-10 classification of psychiatric disorders?
Appeared in: RML MAINS 2025
Explanation
- The International Classification of Diseases, 10th Revision (ICD-10), uses Chapter V (F codes) to classify Mental and Behavioural Disorders.
- The specific block F10-F19 is designated for 'Mental and behavioral disorders due to psychoactive substance use'.
- This category includes disorders arising from the use of alcohol, opioids, cannabinoids, sedatives, cocaine, hallucinogens, tobacco, and volatile solvents.
Why Other Options Were Wrong
- Option A: This block is incorrect because it covers organic mental disorders, which are conditions with a known brain disease, damage, or dysfunction.
- Option C: This block is incorrect as it is reserved for psychotic disorders, which are characterized by severe disturbances in thinking, emotion, and behavior.
- Option D: This block is incorrect. It pertains to disorders where anxiety is a primary feature, or those related to significant life stress and somatic complaints.

- No visual required for this question type.
Clinical Relevance
- Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain ICD-10 classification of psychoactive substance use disorders as background academic context rather than a clinical decision trigger.
- Accurate ICD-10 coding is a fundamental skill for nurses in mental health settings. It is essential for correct diagnosis, creating effective care plans, ensuring proper insurance billing, and contributing to public health data.
- Nurses frequently care for patients with substance use disorders. Understanding this classification helps in communicating clearly with the interdisciplinary team and accessing appropriate treatment resources.
- What if? A patient has a dual diagnosis of both schizophrenia and an alcohol use disorder. The nurse would expect to see codes from two different blocks in the patient's chart: one from F20-F29 (for schizophrenia) and another from F10-F19 (e.g., F10.2 for alcohol dependence syndrome).
How to Approach the Question
- First, identify the key concepts in the question stem: 'psychoactive substance use disorders' and 'ICD-10 classification'.
- Recognize this as a factual recall question that tests your knowledge of a standard medical coding system.
- Mentally review the structure of Chapter V (F codes) of the ICD-10, which covers mental and behavioral disorders.
- Associate each major block of 'F' codes with its corresponding category. For example, F0_ for organic, F2_ for psychotic, F3_ for mood, F4_ for neurotic/anxiety.
- Recall that the F10-F19 block is specifically dedicated to disorders resulting from substance use. This allows you to select the correct option and eliminate the distractors.
