Codes to define venous thromboembolic disease in hospital.


Taken from the paper below, but with minor changes to the type categorisation, to ensure consitency - that intra-abdominal/cranial thromboses are classified as "other" and peripheral thromboses are classified as "dvt".

Codelists are developed by a broad community of users for individual study purposes, which may or may not meet the needs of other studies. They should not be thought of as universal definitions of a particular condition.

We don't offer any guarantees about what they do or don't identify. Users should carefully check that any codelist meets their needs, and seek clinical input where appropriate.
