ICD-API is a REST API that allows programmatic access to the International Classification of Diseases (ICD).

For most users that require accessing the ICD-11 statistical classification with codes, you need to use the Linearization endpoints with the linearizationId set to mms

Foundation endpoints provide information on the Foundation Component of ICD-11.

ICD10 endpoints serves ICD-10 releases. Please note that functionality on the ICD-10 endpoints are limited. (i.e. the search is not provided)
