History of ICD

The first international classification edition, known as the International List of Causes of Death, was adopted by the International Statistical Institute in 1893.

WHO was entrusted with the ICD at its creation in 1948 and published the 6th version, ICD-6, that incorporated morbidity for the first time. The WHO Nomenclature Regulations, adopted in 1967, stipulated that Member States use the most current ICD revision for mortality and morbidity statistics. The ICD has been revised and published in a series of editions to reflect advances in health and medical science over time.

ICD-10 was endorsed in May 1990 by the Forty-third World Health Assembly. It is cited in more than 20,000 scientific articles and used by more than 100 countries around the world.
ICD purpose and uses
ICD is the foundation for the identification of health trends and statistics globally, and the international standard for reporting diseases and health conditions. It is the diagnostic classification standard for all clinical and research purposes. ICD defines the universe of diseases, disorders, injuries and other related health conditions, listed in a comprehensive, hierarchical fashion that allows for:
– easy storage, retrieval and analysis of health information for evidenced-based decision-making;
– sharing and comparing health information between hospitals, regions, settings and countries; and
– data comparisons in the same location across different time periods.

Uses include monitoring of the incidence and prevalence of diseases, observing reimbursements and resource allocation trends, and keeping track of safety and quality guidelines. They also include the counting of deaths as well as diseases, injuries, symptoms, reasons for encounter, factors that influence health status, and external causes of disease.
Introduced in the late 1970s, the ICD-9 code set was replaced by the more detailed ICD-10 code set on October 1, 2015.

What is ICD-10? ICD stands for the International Classification of Diseases, and its codes hold critical information about epidemiology, managing health, and treating conditions. Healthcare professionals use ICD codes to record and identify health conditions. Public health workers can use the recording of ICD codes to see trends in health, and track morbidity and mortality. And insurers use ICD codes to classify conditions and determine reimbursement.
The ICD-10 code set contains roughly five times that number, a total of approximately 69,000 three-to-seven-digit, alphanumeric codes.
Healthcare providers using ICD-10 codes have a better understanding of their patient populations and the conditions that afflict them. Not only can providers make more informed treatment decisions, they also have better information for patient population health management.

ICD-10 codes advance healthcare by:

Improving the overall efficiency of the healthcare industry
Offering updated medical terminology and disease classifications
Improving the accuracy of diagnosis codes
Supporting reimbursement models that pay doctors more for complex issues
Improving payment efficiency and preventing errors
Providing better data for the study of diseases and their patterns
