OPS to SNOMED CT Mapping

TriNetX is committed to supporting global data interoperability initiatives. In Germany, procedure data is coded using Operationen- und Prozedurenschlüssel (OPS) classification system. We partnered with Averbis GmbH to build a partial mapping from OPS to SNOMED CT. Our mapping covers top ~2,000 most frequently used concepts in OPS and accounts for 90% of procedure data by volume.

The mapping process is described in Stefan Schulz, Johannes Steffel, Peter Polster, Matvey Palchuk, Philipp Daumke: Aligning an Administrative Procedure Coding System with SNOMED CT. In: Ontologies and Data in Life Sciences (ODLS 2019) at the Joint Ontology Workshops (JOWO 2019), Graz, Austria, September 23-25, 2019. CEUR Workshop Proceedings, Vol-2518.

We are proud to make this mapping available as open source. For more information please contact
