In addition to the Tabular List, there is an instruction on encoding and a preface with a commentary on the respective version of ICD-10-GM; it also contains information on morphology of neoplasms, some assessment procedures for the documentation of functional impairments and critical values of BMI for children and adolescent persons. All supplementary information is also found in the online versions.
The commentary provides an overview of the most important changes in the current versions compared to that of the previous year. The encoding instructions provide important information on using ICD-10-GM for encoding. In the print version, commentary and instructions preface the actual Tabular List.
The appendix to ICD-10-GM contains the brief versions of some assessment procedures for the documentation of functional impairments pertaining to codes U50-U52:
Metadata for ICD-10-GM contain certain additional information on each ICD-10-GM code that permit certain plausibility tests and statistical grouping also in accordance with ICD-10-WHO special tabulation lists (mortality list, morbidity list). Metadata in machine-readable form are available only in German language from the classifications download centre in the subfolder "Metadaten und Überleitung" (metadata and crosswalks) in the version for the respective year.
The metadata are an enhanced excerpt from the four-character Tabular List of ICD-10-GM. The data include all three-, four- and five-character codes with class titles as well as block and chapter headings. The data are correlated to the special list for the tabulation of mortality and morbidity in the appendix to ICD-10-WHO Tabular List (mortality lists, morbidity lists).
For each individual code, it is defined whether
The metadata allow you to
By themselves, these metadata are not suitable for the development of encoding software, because important parts of ICD-10-GM are missing. Useful work with the classification is not possible without the class attributes of inclusions and exclusions and notes on individual codes.
The DIMDI crosswalk tables match the codes of two successive versions of the classification, in answer to the question: which code of a new version of ICD-10 corresponds to a certain code of a previous version and vice versa. The crosswalk tables are only available in German language from Downloads classifications, subfolder "Metadaten und Überleitung" (Metadata and crosswalk) for the respective version.
Crosswalks between two classifications or two versions of one classification are always determined by their purpose. A crosswalk for epidemiological timelines looks different from a crosswalk for economic mapping for DRG systems.
The DIMDI crosswalks are pure classificatory crosswalks; each code from one version is to be mapped to the code of another version to ensure that the contents of one code are reflected in the other. Such a classificatory crosswalk does not take into account different frequencies or different costs of the diagnoses subsumed under a particular code.
The crosswalk tables make it possible to transcode encoded data to the codes of another version of the classification. Crosswalk tables thus support the continuation of statistical surveys across a version change (timelines).
DIMDI provides ICD crosswalk tables between different versions of ICD-10-GM (SGB-V), between ICD-10-WHO versions and a crosswalk table between ICD-9-WHO 6.0 and ICD-10-WHO 1.3 revisions. The crosswalk tables are available from Downloads classifications in the subfolder for the respective target version. Files liable for fees are available from the DIMDI Webshop.
The crosswalk tables consist of three lists:
In addition to the code pairs "old code" - "new code", there are also two further columns with information whether the crosswalk from old to new or vice versa can be done automatically or has to be performed manually. The latter is the case, for example, if code differentiation has resulted in more than one target code being available for a source code.
The crosswalk from ICD-9-WHO to ICD-10-WHO is done with the help of the crosswalk table between ICD-9-WHO 6.0 and ICD-10-WHO 1.3, available from Downloads classifications in the folder for the target version 1.3 of ICD-10-WHO.
There is no crosswalk from ICD-9 to the SGB-V version of ICD-10.
There are only minor differences between ICD-10-SGB-V version 1.3 and ICD-10-WHO version 1.3: The simplified ICD-10-SGB-V contains only three-character codes for diagnoses that are rare in Central Europe (such as plague: A20.-); the four-character codes have been removed from the systematic index and listed in an appendix. Chapters XX and XXI only include codes required for the purposes of SGB-V.
For that reason, you can proceed as follows:
