ICD-10 Code for Generalized Anxiety Disorder: F41.1
The ICD-10 code for generalized anxiety disorder (GAD) is F41.1. This code is used internationally to identify and classify cases of GAD in clinical and research settings 123456.
Diagnostic Criteria Differences: ICD-10 vs. DSM
Key Criteria and Overlap
While both ICD-10 and DSM systems are used to diagnose GAD, they have important differences in their criteria. Studies show that ICD-10 and DSM-IV/DSM-5 often identify different groups of people with GAD, with only moderate agreement between the systems 1235. For example, ICD-10 requires symptoms of autonomic arousal and excludes cases with certain comorbid disorders, while DSM-IV/5 focuses on excessive worry and significant distress or impairment 13. As a result, not all individuals diagnosed with GAD under one system will meet the criteria under the other 1235.
Prevalence and Comorbidity
Research indicates that the prevalence rates for GAD are similar between ICD-10 and DSM systems, but the actual individuals diagnosed may differ significantly 12. There is also a high rate of comorbidity with depression and other psychiatric disorders among those diagnosed with GAD, regardless of the classification system used 24.
Clinical and Research Implications
ICD-10 is widely used in clinical practice, especially in Europe, while DSM criteria are more common in research settings . This means that the populations identified as having GAD may differ depending on which system is used, which can affect both treatment and research outcomes 56.
Conclusion
The ICD-10 code for generalized anxiety disorder is F41.1. While ICD-10 and DSM systems are similar in some ways, they use different criteria and often identify different individuals as having GAD. Understanding these differences is important for accurate diagnosis, treatment, and research.
