The ICD is a classification of health-related problems and was established around 1850. The World Health Organization (WHO) manages the ICD. This classification is part of a collection of international classifications. It functions as language-independent frameworks and is available in more than 40 languages. Healthcare providers use the ICD to register health problems in the patient’s file. The WHO uses these classifications for national mortality and morbidity statistics.
The ICD components
The ICD-10 is the latest version of the internationally standardized classification system of diagnoses.
The ICD-10 is made up of three parts:
Part 1 contains an alphanumeric classification of categories and codes for diseases, external causes of injury and poisoning, symptoms, abnormal clinical findings, laboratory results, factors influencing health status and contacts with healthcare.
Part 2 is a manual for use and includes an introduction to the classification and history of the ICD. This section contains the certification and classification rules. Part 2 also contains useful definitions and reporting requirements for coded data and statistical presentation of this data.
Part 3 is an alphabetical list of diseases and disorders and the associated code in the systematic list. The alphabetical list was developed to select user categories and associated codes based on clinical terms describing diseases and other health conditions. Part 3 has separate sections for diseases, external causes of injury and medicines and other chemicals.
Statisticians and epidemiologists use the ICD for national registrations such as the Hospital Standardized Mortality Ratio, the National Basic Registration Hospital Care and monitoring the spread of diseases. At the same time, the ICD is used for the national statistics published by Statistics Netherlands.
