azuma hashi is a fundamental module to provide your medical professional users with master data they need to simplify their processes and workflows. Based on state-of-the-art technology, hashi offers easy access and is easy-to-integrate into your digital health solution.


Our GraphQL API is perfect to customize your requests and allows for flexible data access. We take care about all data updates and ensure that the most recent versions of master data sets are applied. Currently we focus on medical terminologies (SNOMED, ICD, MedDRA, …) plus their mappings and KBV master data. Our roadmap is inspired by the German Interop Council:
