What is the main term and correct code assigned for paranoid reaction?

In the context of medical coding, particularly when addressing psychiatric conditions, the main term is crucial for identifying the correct diagnosis code. For paranoid reactions, the appropriate coding involves both the main term and the specific classification under the International Classification of Diseases (ICD).

The term "paranoid reaction" falls under the category of psychotic disorders, and the code F23 specifically refers to acute and transient psychotic disorders that include paranoid reactions. This makes F23 the most relevant and accurate choice when classifying this particular mental health condition.

Understanding the categorization of mental health disorders is essential in medical coding, and recognizing that paranoid reactions are classified within the psychotic disorder range helps in correctly identifying the associated code. Other options do not appropriately classify paranoid reactions or refer to different conditions that do not align with paranoid reactions specifically. Thus, selecting the main term "Reaction" paired with the code F23 is aligned with the established coding practices for this type of mental health condition.
