What is the coding system developed by the World Health Organization known as?

The coding system developed by the World Health Organization is known as ICD, which stands for the International Classification of Diseases. This system is designed to systematically categorize diseases, health-related issues, and other factors influencing health. The ICD codes are used globally for various purposes, including health management, population health assessment, and health care billing.

ICD codes help ensure a standardized method for classifying diseases, facilitating the collection, comparison, and analysis of health information across different settings and populations. This coding system evolves over time to incorporate new knowledge and advancements in medicine, with the most recent version being ICD-11.

While other codes like CPT (Current Procedural Terminology) are used primarily in the United States for reporting medical procedures and services, and DSM (Diagnostic and Statistical Manual of Mental Disorders) focuses on mental health diagnoses, these are not developed by the World Health Organization. HCPCS Level II codes are utilized for billing specific non-physician services and are maintained by the Centers for Medicare & Medicaid Services. Thus, the ICD is the correct coding system associated with the World Health Organization.
