What organization created ICD-9-CM?

  1. American Medical Association

  2. World Health Organization

  3. Centers for Disease Control and Prevention

  4. Food and Drug Administration

The correct answer is: World Health Organization

The correct answer is the World Health Organization (WHO). The WHO is responsible for creating and updating the International Classification of Diseases (ICD) coding system. ICD-9-CM was developed based on the WHO's ICD-9 system with modifications made specifically for use in the United States healthcare system. The other options - American Medical Association, Centers for Disease Control and Prevention, and Food and Drug Administration - do not have direct involvement in the creation of the ICD coding system.
