Understanding the ICD System and Its Relevance to Anxiety Disorders
What Is the ICD Coding System?
The International Classification of Diseases (ICD) is a globally recognized system developed and maintained by the World Health Organization (WHO). It provides a standardized language for diagnosing and classifying diseases, disorders, injuries, and other health conditions. The ICD codes are used extensively in healthcare settings for billing, epidemiology, and health management.
Why Is ICD Coding Important for Anxiety Disorders?
Accurate ICD coding for anxiety disorders ensures:
- Proper documentation for medical records
- Appropriate insurance claims processing
- Data collection for public health monitoring
- Research and analysis of mental health trends
- Effective communication among healthcare providers

ICD Codes for Anxiety Disorders
Main ICD-10 Codes for Anxiety Disorders
The ICD-10 classification, which is widely used internationally, categorizes anxiety disorders primarily under the section F40-F48, which encompasses neurotic, stress-related, and somatoform disorders. The main codes include:
- F40 - Phobic Anxiety Disorders
- F41 - Other Anxiety Disorders
- F42 - Obsessive-Compulsive Disorder
- F43 - Reaction to Severe Stress, and Adjustment Disorders
Each of these categories contains specific codes for various diagnoses.
Common ICD-10 Codes for Anxiety Disorders
Below are some of the frequently used ICD-10 codes related to anxiety:
- F40.0 - Agoraphobia
- F40.1 - Social Phobia
- F40.2 - Specific Phobia
- F41.0 - Panic Disorder [episodic paroxysmal anxiety]
- F41.1 - Generalized Anxiety Disorder
- F41.2 - Mixed Anxiety and Depressive Disorder
- F42 - Obsessive-Compulsive Disorder (OCD)
- F43.0 - Acute Stress Reaction
- F43.1 - Post-Traumatic Stress Disorder (PTSD)
These codes facilitate precise diagnosis documentation and are essential for clinical and administrative purposes.

Transition to ICD-11 and Its Impact on Anxiety Coding
Introduction to ICD-11
The World Health Organization released ICD-11 in 2018, aiming to modernize disease classification and improve clinical utility. ICD-11 introduces updated categories and codes for mental, behavioral, and neurodevelopmental disorders, including anxiety.
ICD-11 Codes for Anxiety Disorders
In ICD-11, anxiety disorders are categorized under the broader heading of "Fear-related disorders" and "Anxiety or fear-related disorders," with specific codes designed for clarity:
- 6B00 - Specific Phobia
- 6B01 - Social Anxiety Disorder
- 6B02 - Panic Disorder
- 6B03 - Agoraphobia
- 6B04 - Generalized Anxiety Disorder
- 6B0Z - Other specified anxiety or fear-related disorder
The transition to ICD-11 aims to enhance diagnostic accuracy and facilitate international research efforts.
