Which organization first published the ICD manual?

The International Classification of Diseases (ICD) manual was first published by the World Health Organization (WHO). This organization is responsible for coordinating international health efforts and developing standard classifications for diseases and health conditions, making it a leading authority in global health issues. The primary purpose of the ICD is to provide a systematic way of coding diseases and health-related problems, which enables health care providers and researchers to share data and improve health care systems worldwide.

The other organizations listed, such as the American Medical Association, U.S. Department of Health and Human Services, and AHIMA, play important roles in health care and administration but are not the original publishers of the ICD manual. Their contributions are significant, but the WHO's role in creating the ICD reflects its foundational goal of enhancing health data comparison and statistical reporting across different countries.
