Who publishes the International Classification of Diseases (ICD)?

The International Classification of Diseases (ICD) is published by the World Health Organization (WHO). This global health authority is responsible for the development and maintenance of the ICD, which is an essential tool for the classification of health conditions and diseases. The ICD is utilized worldwide for the coding of diseases, ensuring that health data is standardized and can be compared across different settings and countries.

The WHO's involvement in the ICD underscores its role in promoting international health research and epidemiology. The classification aids in understanding disease patterns, allocating resources, and enhancing health policies globally.

Other organizations like the Centers for Disease Control and Prevention (CDC) and the National Institutes of Health (NIH) play important roles in public health and medical research in the United States, but they do not publish the ICD. The American Medical Association (AMA) focuses on physician advocacy, education, and standards in healthcare, but it is also not involved in the publication of the ICD. Thus, the key role of the WHO in developing and updating the ICD makes it the correct answer in this context.
