MedCode Vocabularies

Structured biomedical terminology datasets powering MedCodeTranslator — an open-source biomedical terminology retrieval platform.

Dataset Description

A collection of standardised medical code systems in a unified JSON format, ready for use in retrieval, search indexing, NLP pipelines, and clinical terminology mapping.
