Kodality

business overview

Kodality focuses on mission-critical software for healthcare and public services.

Founded in 2017 and headquartered in Tallinn, the company brings together a team of thirty specialists and more than 250 years of cumulative experience in complex software delivery.

We are a trusted partner of the Estonian Ministry of Social Affairs in building the next generation of national electronic health records and transitioning the national data exchange standard from HL7 v3 CDA to HL7 FHIR.

Building on our strength in FHIR-based interoperability, semantic standardisation, and national-scale health data architecture, we ensure that health data becomes standardised, connected, and clinically reliable across care settings, institutions, and regions. Two of our key components – the KeFHIR interoperability server and the TermX terminology platform – have become part of Estonia’s national healthcare backbone and were contributed to the government as open-source solutions.

As engineers at heart, we combine deep expertise with a strong commitment to public value. Kodality supports healthcare organisations in Europe and North America in adopting HL7 FHIR and implementing interoperability and terminology services, bringing Estonia’s practical experience into international projects.

core competencies

Kodality combines expertise in health data standards, cross-system data integration, and clinical terminology to make health information usable across organisations and regions:

• Local, national and regional health data platforms – design and implementation of scalable health information systems and electronic health record platforms using HL7 FHIR,
• Interoperability and FHIR standard implementation – design and implementation of interoperability layers based on HL7 FHIR. This includes modelling and profiling data, migrating from legacy formats (such as HL7 v3 CDA) to FHIR, designing APIs, and ensuring forward and backward compatibility of evolving FHIR resources with existing ecosystems,
• End-to-end support for clinical terminology governance – Kodality helps organisations implement and manage SNOMED and national classifications, including mappings, value sets, concept maps and release processes, so that semantics remain consistent across clinical documentation, billing, reporting and analytics and different teams can rely on the same meaning of data,
• Integrated health and social care services – design of digital backbones for care coordination and cross-agency collaboration in regions facing complex health and social challenges,
• Tailored consulting, architecture design and delivery – end-to-end services from technical strategy, architecture and standards implementation through to software development, rollout and optimisation for mission-critical systems.

value proposition

Health authorities and ministries work with Kodality when they need their e-health strategy to turn into the services that clinicians actually use. Coming from Estoniaʼs digital health ecosystem, our team has helped design and build FHIR-based interoperability layers and national services – such as the Dataviewer patient information portal – that are actively used by hundreds of providers and millions of citizens.

We translate this experience internationally, so organisations worldwide can benefit from what worked in Estonia instead of starting from scratch.

For our partners, this means:

• Lower programme risk – a partner who has already delivered FHIR-based infrastructure at national scale, not just single-hospital projects,
• Faster time to impact – starting from ready FHIR servers, terminology tooling and implementation expertise instead of building everything in-house,
• No vendor lock-in – open standards and open-source components under the clientʼs control, with space for local vendors and integrators to participate,
• Data that is ready for AI and analytics – a strong semantic layer (terminologies, mappings, value sets) so health data is not only exchanged but also understood and reusable for decision-making and innovation,
• Solutions anchored in real workflows – co-design with hospitals, municipalities and agencies to ensure platforms match how professionals actually work and can scale nationally.

As a result, Kodality is chosen for projects where precision and flawless execution are non-negotiable and where public trust in digital health infrastructure must be maintained over years.

our vision

Kodalityʼs vision is a world where:

• Health data follows the person, not the institution,
• Every system understands and carries over the meaning of the data it exchanges,
• Trust is built into the architecture – patients can see how their data is used, and health professionals can rely on the information in front of them.

We see our work as a public good: the invisible rails that allow healthcare, social care, and research to work together in real time.

portfolio

• KeFHIR – a stable and reliable open-source FHIR interoperability server for local, national and regional health systems, proven as part of Estoniaʼs national healthcare backbone.
• TermX – a unique open-source terminology platform for the management of clinical terminologies that underpins national-scale health data standardisation.
• Andmevaatur (Dataviewer) – a national-level solution that transforms HL7 v3 CDA data from multiple sources into a FHIR-based model and presents it in a user-friendly web portal, giving clinicians a unified view of patient records.
• HEDA – the most comprehensive hospital information system in Estonia that supports the full patient journey and hospital operations, from resource planning and first contact with the patient through treatment, discharge, billing and advanced reporting. It is designed as an enterprise-grade platform for providers that need end-to-end digital support for clinical and administrative workflows, not just electronic documentation.
