OPS
The German procedure classification (Operationen- und Prozedurenschlüssel - OPS) is the official classification for the encoding of operations, procedures and general medical measures.
The currently valid version is OPS 2024.
The OPS is available in various versions and formats in German language and is updated annually. The currently valid version is effective from the beginning until the end of a calendar year. In the case of corrections during this period of validity you will be informed by our newsletter (in German language).
Code search OPS online
The online versions each consist of up to 100 individual files. The integrated code search and the high density of links enable convenient navigation between the codes within the entire classification. Under "Ergänzende Informationen" you will find the files from the preamble and appendix to the OPS.
Downloads
The OPS is offered in different versions and formats. All files are free of charge. With the download of files a contract of use between you and the BfArM comes into being. You can view the download conditions in a PDF version before downloading.

Structure of OPS
OPS consists of two parts:
- Tabular List: consisting of the hierarchically ordered list of codes together with supplementary information: The preface contains information about the encoding process and a commentary on the most important changes compared to the previous version. The appendix contains instructions on the calculation of expenditure points for complex intensive care treatment.
- Alphabetical Index: as a collection of designations of operations and other procedures that can be encrypted with the official OPS (each with associated code); since version 2021, the Alphabetical Index will be provided exclusively as TXT(CSV) version, a version as ODT or PDF will no longer exist.
The preface of OPS contains information for its use. However, the sector-specific coding guidelines should be regarded in the application.
OPS as adaptation of ICPM by WHO
OPS is an adaptation of the International Classification of Procedures in Medicine (ICPM) of the World Health Organisation (WHO). The German version of the ICPM was developed on the basis of a translation of the extended Dutch version ICPM-DE (Dutch Extension). This was developed into OPS. Until 2004, OPS was known as OPS-301 (301 refers to § 301 SGB V stipulating the application of OPS). OPS is a version adapted to the specific requirements of the German health care system. It is currently revised on an annual basis in cooperation with the self-governing partners in the German healthcare system under the lead management of BfArM.
