The Tabular List of OPS is supplemented with the following additional information, included in the print version either as a preface or as an appendix. In the online versions, this information is available under the tab "Zusatzinformationen" (Supplementary information). The OPS online versions are available only in German language.
The commentary provides an overview of the most important changes in the current versions compared to that of the previous year. The user instructions contain information on encoding with OPS. The list of abbreviations contains all abbreviations used in the Tabular List. In the print edition, commentary, user information and list of abbreviations preface the Tabular List; in the online version, they are found under "Zusatzinformationen" (Supplementary information).
The documents "Berechnung der Aufwandspunkte für die Intensivmedizinische Komplexbehandlung" (Expenditure points for complex intensive care treatment) contain tables required for the calculation of expenditure points for complex intensive care for adults (SAPS, TISS) (code 8-980) and children (code 8-98d). Using the tables with the complex care measures scores (PKMS), the expenditure points for the highly complex care of patients are calculated (codes under 9-20). In the print edition, the tables for the calculation of expenditure points are included as an appendix; in the online versions, they are found under "Zusatzinformationen" (Supplementary information).
You will also find some lists for coding individualised vs. group therapy.
The metadata are a preprocessed excerpt from the Tabular List of OPS. The data include all four-, five- and six-character codes with class titles as well as titles for three-character codes, blocks and chapters. The crosswalk table permits the transcoding of codes from the old version to the corresponding codes of the new version of OPS and vice versa.
The metadata of OPS provide additional information for each OPS code that permit e.g., certain plausibility checks or statistical groupings. Metadata in machine-readable ASCII-form are available only in German language from Downloads classifications in the subfolder "Metadaten und Überleitung" (metadata and crosswalk) in the version for the respective year.
The metadata of OPS are an enhanced excerpt from the OPS Tabular List. The data include all four-, five- and six-character codes with class titles as well as titles for three-character codes, blocks and chapters.
For each code, they contain information, e.g. as to whether
The metadata allow you to
By themselves, these metadata are not suitable for the development of encoding software because important parts of OPS are missing. Useful work with the classification is not possible without the class attributes of inclusion notes, exclusion notes and notes on individual codes.
The crosswalk tables make it possible to transcode codes from a particular version of the classification to the codes of another version. The crosswalk tables are only available in German Language from Downloads classifications in the folder for the respective version, subfolder "Metadaten und Überleitung" (Metadata and crosswalks).
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 crosswalk tables 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 procedures 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).
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.
