OpenCodelists

Welcome to OpenCodelists, created by OpenSAFELY for creating and sharing codelists.

Anybody can also use this tool to create and share codelists. To get started, take a look at the documentation or watch the videos.

If you would like to publish codelists on behalf of an organisation, please get in touch.
