West Coast Informatics says MT2 is now in production in Norway

West Coast Informatics says its open source mapping tool MT2 is now being used in production by the Norwegian Directorate of Health. The company says the rollout shows the tool can support national-scale terminology mapping and is now available to other organizations.

Why it matters: - MT2 is designed to cut repetitive work in terminology mapping and reduce errors in healthcare coding workflows. - The tool is now in production at a national health authority, which WCI says demonstrates it can handle large-scale use. - Open source availability means other organizations can adopt the same mapping workflow without building a tool from scratch.

What happened: - West Coast Informatics announced that MT2 is now in production at the Norwegian Directorate of Health. - Norway’s national terminology team uses MT2 for daily mapping work. - WCI says MT2 is now available to any organization that builds or maintains terminology maps. - The announcement was made on October 18, 2026.

The details: - MT2 is an open source tool for mapping between coding systems. - Healthcare organizations use coding maps to connect systems such as local lab codes to national standards or SNOMED CT® to ICD-10. - MT2 gives mappers suggested matches instead of starting from a blank screen. - MT2 supports bulk updates across large sets of records. - Newer mappers can use a guided view of each record. - Experienced mappers can work in a table view. - MT2 connects directly to an organization’s terminology server. - That connection keeps maps checked against current content and ready to release when the team is ready. - For multilingual projects, MT2 shows source terms side by side in each language. - MT2 also supports complex maps, including SNOMED CT to ICD-10. - Norway’s mapping team says bulk mapping has sped up work and reduced the risk of human error.

Between the lines: - The Norway deployment is a proof point for a tool aimed at a task that is essential but often manual and slow. - WCI is positioning MT2 as both a product and a shared infrastructure layer for terminology teams. - The open source model could make adoption easier for public sector and health system teams that want local control over data and access. - The collaboration with Norway’s terminology mappers suggests MT2 features were shaped by real-world mapping workflows rather than only product design.

What's next: - WCI and Trine Angelskår of the Norwegian Directorate of Health will present MT2 at SNOMED CT Expo 2026 in Sydney on October 22. - The session is titled “MT2: Scalable Terminology Mapping Across SNOMED CT and Beyond.” - Visitors will also be able to see MT2 at the WCI booth. - Organizations can run MT2 on their own infrastructure or have WCI host it. - WCI also offers support under a service agreement, including initial mapping, review, or publishing help. - Customers keep full ownership and control of their maps. - WCI says the MT2 source code is available on GitHub.
