Our cloud-base, multi-tenant Medical Terminology API enables centralized management of fundamental reference information covering clinical, claim, and provider domains.  Take full advantage of semantic harmonization and reasoning across vocabularies and databases to achieve interoperability, compliance, and operational efficiency.  No medical linguistics expertise is required for business users to search, find, edit or build from scratch relevant concept groups (i.e., value sets) that power Clinical Quality Measures (CQM), Machine Learning (ML) or Natural Language Processing (NLP) queries and applications.

Unified Access To A Vast Repository

How does your organization recognize semantically similar exposures, events, encounters and episodes across disparate source systems (e.g., clinical and claims), across different vocabularies that comprise different concepts or codes? Our Medical Terminology API makes the complex simple by enabling exhaustive identification of records, patients or providers by the exposures, events, encounters and episodes that define your search criteria. Browse, select, copy and edit or use our administrative console to build your own semantically aligned concept groups (i.e., value sets) from scratch.  We have pre-built thousands of validated, semantically aligned concept groups which are offered as a content layer within our Medical Terminology API.

Access the universe of medical terminology.  We help you systematically govern and manage your medical terminology reference data as organizational assets.
