Which organization is responsible for maintaining the ICD coding system?

The organization that maintains the ICD (International Classification of Diseases) coding system is the World Health Organization (WHO). ICD is a globally recognized standard for health information, which allows for the systematic collection and analysis of health statistics. The WHO is responsible for developing and updating this classification, ensuring it remains relevant to the evolving needs of public health, and promoting its use internationally.

Other organizations, while they have important roles in health and medical coding, do not manage the ICD directly. For instance, the Centers for Disease Control and Prevention (CDC) is involved in the application of ICD codes in the United States but does not maintain the coding system itself. The American Medical Association (AMA) is focused on developing and promoting codes for various medical procedures and services, particularly the Current Procedural Terminology (CPT) codes. The National Institutes of Health (NIH) plays a significant role in health research but is not responsible for maintaining coding systems like ICD. Thus, the most accurate answer regarding the management of the ICD coding system is indeed the World Health Organization.
