ICD-11

The ICD-11 is the 11th version of the international statistical classification of diseases and related health problems (ICD: International Statistical Classification of Diseases and Related Health Problems ). The purpose of the ICD is to enable the systematic collection, analysis, interpretation and comparison of mortality and morbidity data collected in different countries or areas and at different times. All World Health Organization (WHO) member states are expected to use the current version of the ICD for reporting death and illness. The ICD-11 is scheduled to come into force on January 1, 2022; Only after a flexible transition period of 5 years should causes of death be coded exclusively with the ICD-11. It is not yet possible to make any statements about the specific time of the introduction of the ICD-11 in Germany.

The ICD is a classification of the WHO Family of International Classifications (WHO-FIC). The most common geographic and historical use of the ICD is the statistics of causes of death. The ICD is also used to classify clinical documentation and as a framework for legislation. The history of the development of the ICD is described in chapter 1.7 of the reference manual for the ICD-11.

Taxonomy

A statistical classification of diseases must be limited to a limited number of mutually exclusive categories that can cover the entire spectrum of pathological conditions. Consequently, each classification contains residual categories for other and other conditions that cannot be assigned to the more specific categories. The following criteria determine whether an entity can be classified as a unique category:

1. Epidemiological evidence: frequency analyzes of coded mortality and morbidity data
2. Clinical evidence: Evidence of illness in the medical specialties
3. Granularity: Minimum information useful for mortality (mortality data) or basic care
4. Continuity: The level of detail in the ICD is retained
5. Thrift: the need to limit the number of categories for international reporting

If a higher level of detail of the coding is required, additional codes can be added.

Chapter structure

The ICD is a variable axis classification. The chapter structure goes back to a suggestion by William Farr from the beginning of the international discussion about the classification structure. The chapter structure has worked well in practice and is considered more useful for general epidemiological purposes than any of the alternatives tested.

Code pattern

1. Characters: Number or letter, designates the chapter
2. Characters: Letters, O and I are not used due to the risk of confusion with the digits 0 and 1
3. Characters: digit
4. Characters: digit or letter

Extension codes have an X as the first character and must not be used alone.

Basic component and tabular lists of the ICD – 11

The basic component of the ICD-11 is a multidimensional collection of all ICD entities. All entities have a Uniform Resource Indicator (URI) and have a specific position in a hierarchy of groups, categories, and narrower terms. Entities can be more or less broad, such as B. "Injury to the arm" or "Injury to the skin of the thumb". The base component contains the information necessary to use the entities to create a tabular list. The basic component also stores whether the entity is a grouping, a category in a master code or an inclusion term in a certain category in a tabular list. In a tabular list, the entities of the base component become categories. The categories are mutually exclusive and exhaust themselves together.

Revision process

A standardized revision process was set up. The update takes place at different levels with different frequencies. Anyone can propose an update to the ICD. All proposed changes must be submitted through the online proposal mechanism. The suggestions are checked by experts and run through a workflow. All changes are published in the form of a change list.
