How many codes are contained in ICD-10?

The number of codes in the International Classification of Diseases, Tenth Revision (ICD-10), is approximately 70,000. This system was developed by the World Health Organization (WHO) and expanded significantly from its predecessor, ICD-9, to allow for a much more detailed and comprehensive classification of diseases, conditions, and health-related issues. The increase in the number of codes reflects the need for more specificity in the diagnosis and billing processes in healthcare.

ICD-10 includes a wide variety of codes across various chapters that detail different conditions, which can include not only diseases but also injuries, symptoms, and external causes of disease and injury. The comprehensive nature of ICD-10 enables healthcare providers to communicate more effectively regarding the diagnosis and management of diseases, ultimately improving healthcare delivery and data collection.
