This project, called ICD, lets you search and browse the World Health Organization's International Classification of Diseases. It's a standardized list of medical codes and descriptions that healthcare systems worldwide use to categorize diseases, symptoms, and treatments. The tool provides this data in both English and Spanish, and you can look up conditions either through a web browser or by pulling the data programmatically. At its core, the project is a web application built with Ruby. It comes with ready-to-use database files containing all the disease classifications, so after a quick setup you get a searchable website. You can click through chapters and specific disease codes in your browser, or if you're building software that needs to reference these codes, you can append ".json" to any URL to get the data back in a format your application can read. For updating the underlying data, the project uses a tool called Pentaho Data-Integration to process new files from the WHO. This would be useful for anyone building healthcare or medical software who needs their application to understand ICD codes. For example, if you're creating a patient records system and need doctors to select a standardized diagnosis code, or if you're building an insurance claims tool that needs to match conditions to their official WHO classifications, this gives you both the data and a way to serve it. The API makes it straightforward to pull disease information into your own product. One important thing to note is that this repository is no longer maintained. The creator points users to a separate project called icd.json instead. So if you're considering using this today, you'd want to look at the replacement project first, as it likely offers the same disease classification data in a more current and supported form.
