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.

Below, you'll find all the codelists we have used in OpenSAFELY research to date.

Acute transverse myelitis ICD-10 ICD-10

Acute transverse myelitis ICD-10 codelist for use with hospital and mortality data

Codelist aims to be specific rather than sensitive, and to describe acute transverse myelitis occuring on its own rather than myelitis as part of a broader disease process such as encephalomyelitis or ADEM. Does not include codes which are not specific to acute transverse myelitis, e.g. such as 'Encephalitis, myelitis and encephalomyelitis'.
