What are ICD-10 codes?

The International Classification of Diseases, Tenth Revision (ICD-10) is a worldwide coding system that classifies diseases and various signs, symptoms, abnormal findings, and external causes of injury or disease. These codes standardize the diagnosis across different healthcare providers and settings, enabling clear communication and facilitating research and epidemiological studies.


ICD-10 codes are essential for the documentation and billing of healthcare services. They help accurately describe a patient's diagnosis and ensure that healthcare providers are reimbursed for their services. Additionally, they assist in epidemiological research, allowing for the monitoring of disease prevalence and the effectiveness of treatment modalities.

How to decipher the ICD-10 code structure

ICD-10 codes are alphanumeric, with the first letter indicating the chapter of diseases they belong to. The subsequent characters specify the condition more precisely. For mental health, codes typically begin with an "F," indicating they fall under Chapter 5, which covers mental, behavioral, and neurodevelopmental disorders.

How is ICD used to diagnose mental health disorders?

ICD codes offer a standardized language for diagnosing and categorizing mental health conditions. Behavioral health professionals use these codes to document diagnoses accurately. This standardization facilitates communication between healthcare providers and supports consistent treatment approaches.
