What is a Terminology Server and Why Do They Matter?
What is a Terminology Server?
In today’s interconnected healthcare landscape, ensuring that digital health systems, healthcare providers, and industry-based organizations “speak the same language” is crucial for effective data exchange and patient safety. This is where terminology servers come in.
They act as specialized tools designed to manage, store, and deliver standardized healthcare terminologies such as SNOMED CT, LOINC, and ICD-10-CM or even custom/local data sets. Terminology servers function as the backbone for interoperability, enabling systems to interpret, validate, and utilize clinical data consistently across diverse environments.
A terminology server functions as a central hub, bridging the gap between disparate systems by providing reliable access to up-to-date terminologies. This ensures that clinical information retains its meaning and usability, whether for patient care, analytics, or compliance. Modern terminology servers often support features like real-time updates, API integrations, and tailored project configurations, which allow them to adapt to the evolving needs of healthcare stakeholders.

Why are Terminology Servers Important?
Terminology servers play a pivotal role in modern healthcare systems, ensuring the effective management of terminologies required for interoperability and organizational growth. By centralizing and streamlining how healthcare terminology standards are accessed and maintained, they provide the foundation for consistency, scalability, and accuracy in data exchange. Below are the key ways terminology servers simplify and enhance the management of healthcare data:
Data Interoperability: Terminology servers provide standardized access to terminologies, enabling systems to exchange data using widely accepted code systems like SNOMED CT, LOINC, and ICD-10-CM, as well as custom or local code systems. By supporting concept mappings and value sets, they facilitate seamless data exchange both within and across code systems. These capabilities are crucial for meeting interoperability requirements, including those defined by TEFCA in the U.S. TermHub simplifies this process by enabling streamlined terminology selection tailored to specific use cases.
Centralized Management: Terminology servers can act as a “single source of truth” for managing and accessing code system data. They allow organizations to add or remove code systems and manage versions from a single, centralized location. With stable APIs, they streamline terminology access, reducing complexity for developers and enhancing operational efficiency. This approach ensures consistent terminology usage across systems and minimizes errors caused by misaligned or outdated data. TermHub offers a developer-friendly Swagger interface for API integration testing including for FHIR APIs.
Accuracy and Reliability: Terminology servers provide organizations with controlled access to the terminology standards required for their specific needs, whether the latest version or older ones. By maintaining strict version control and supporting access to multiple versions, they ensure consistency in how terminologies are accessed and utilized. This structured approach supports compliance with regulatory and project-specific requirements while aligning systems with organizational priorities. With TermHub, updated terminologies are made available for project inclusion immediately upon publication.
Separation of Concerns: By managing and delivering access to the necessary terminology standards, terminology servers offload the complexity of handling these frameworks. This enables organizations to focus on core projects, processes, and solutions, without redirecting resources to intricate terminology management. TermHub supports multi-project and multi-tenant environments, ensuring streamlined terminology utilization across diverse teams and workflows.
Scalability and Flexibility: As healthcare organizations expand or their needs evolve, terminology servers enable the integration of additional standards or custom terminologies with minimal disruption. Designed to scale with organizational growth, they seamlessly accommodate expanding users, applications, and data flows while ensuring long-term adaptability to evolving requirements such as specialized terminologies or regulatory changes. TermHub offers cloud-based terminology management, allowing users to customize and adapt selections as needs change.

What Content Does a Terminology Server Contain?
A terminology server stores and manages three core types of artifacts essential for healthcare data standardization: code systems, concept mappings, and value sets. Each artifact plays a specific role in enabling interoperability and efficient data exchange.
Code systems are comprehensive collections of standardized codes, such as SNOMED CT, LOINC, and ICD-10-CM, as well as local, custom-developed systems tailored to an organization’s needs. These code systems often include multiple versions, allowing organizations to work with current standards or older versions required for legacy systems or specific projects.
Concept Mappings define relationships between different code systems, such as linking local lab codes to LOINC or creating crosswalks between ICD-10-CM and SNOMED CT. By leveraging predefined resources, terminology servers apply these mappings to align data across systems. This functionality ensures that data can flow seamlessly between applications, enabling interoperability while reducing manual effort.
Value sets are curated subsets of codes drawn from one or more code systems. They are designed for specific use cases, such as clinical documentation, decision support, reporting, or regulatory compliance. For example, a value set may include all SNOMED CT codes representing infectious diseases or all LOINC codes used for cardiac lab tests. Like code systems and mappings, value sets can have multiple versions to support evolving requirements, ensuring compatibility across different workflows.
A properly designed terminology server ensures that all versions of these three artifact types—whether standard or local—are accessible and usable. It provides the flexibility to select one or more versions of a code system, mapping, or value set for different workflows or projects. Additionally, terminology servers allow users to search and explore these artifacts, making it easy to locate specific codes, mappings, or value sets for integration, analysis, or operational use.
How Do They Work?
Terminology servers operate through robust APIs, which provide standardized ways to query, retrieve, and manage terminology data. These APIs form the backbone of how terminology servers integrate into healthcare workflows, ensuring seamless access to the terminologies required for interoperability.
Users interact with terminology servers in different ways based on their roles, leveraging their features to meet specific needs:
Healthcare Professionals and Analysts: Use web interfaces or query tools to search for terms, create value sets, or explore relationships between concepts for clinical or operational purposes.
Developers: Access APIs to embed terminology functionality into applications, enabling tasks like retrieving standardized codes, validating clinical entries, and supporting workflows such as reporting or decision support.
Systems also rely on terminology servers programmatically, often in real time. For example, an EHR might query a terminology server to validate a code during clinical documentation or fetch a value set for use in analytics. Similarly, a lab system might use the server to ensure alignment with LOINC when exchanging lab results across organizations. By acting as intermediaries, terminology servers ensure consistent and reliable use of standards across all interacting systems.
A cornerstone of most modern terminology servers is their support for FHIR (Fast Healthcare Interoperability Resources), a widely adopted standard for healthcare data exchange. The FHIR Terminology Service API defines operations like concept lookups, value set expansions, and mapping execution, making integration with healthcare systems simpler and more consistent. TermHub supports both FHIR R4 and R5, enabling advanced operations like real-time validation and batch processing for concept mappings, ensuring seamless integration with evolving interoperability standards.
TermHub also offers dynamic updates to healthcare terminologies, ensuring that organizations always have access to the latest versions and can adapt quickly to changing compliance or project needs. Additionally, TermHub provides developer-focused resources, including interactive API documentation and quick-start guides, making it easier for teams to implement and leverage FHIR capabilities.
In summary, terminology servers act as a bridge between users, systems, and terminologies, ensuring that healthcare data is standardized, accurate, and interoperable. Whether accessed through APIs, user interfaces, or real-time system interactions, they simplify the complex task of terminology management, driving better data exchange and outcomes in healthcare.
