About
Description
This codelist was developed in 2022 by Campbell and colleagues (https://onlinelibrary.wiley.com/doi/full/10.1002/pds.5584) for the purposes of identifying pregnancy in CPRD Aurum. It is designed to be highly sensitive, to identify any potential pregnancy (including potentially unconfirmed pregnancies and pregnancies not resulting in birth). It expands on a 2019 ICD-10 codelist developed by the same group for CPRD GOLD (https://onlinelibrary.wiley.com/doi/full/10.1002/pds.4811).
The codelist is contained in the appendix 7 of supplementary information.
Methodology
The original ICD-10 codelist by Campbell 2022 contains 560 codes. However, 10 of them are erroneous, duplicate M83.0 (puerperal osteomalacia). They are not present in the ICD-10 reference checker, nor ever been used in HES data (2015-2023), nor accepted by Open Codelists. They are M830.0, M830.1, M830.2 and so on until M830.9. These codes have been removed, resulting in a total of 550 codes.
All codes contained in the 2019 CPRD GOLD ICD-10 codelist are fully contained in this updated 2022 codelist.

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.
