    This codelist was taken from OpenCodelists, created by OpenSAFELY. We recommend viewing this Phenotype on the OpenCodelist website to view the most recent version.

    Bell's palsy - relevant code from ECDS restricted reference set of SNOMED codes

    © University of Oxford for the Bennett Institute for Applied Data Science 2025. This work may be copied freely for non-commercial research and study.

  3. Methodology

    The ECDS dataset is coded in SNOMED using a restricted reference set of SNOMED codes, as described here https://datadictionary.nhs.uk/data_elements/emergency_care_diagnosis__snomed_ct_.html https://dd4c.digital.nhs.uk/dd4c/publishedmetadatas/intid/710

    Searched ECDS data dictionary re Bell's palsy, as documented on Github https://github.com/opensafely/codelist-development/issues/135

    The restricted reference set includes one SNOMED code for Bell's palsy: 193093009 Bell’s palsy (disorder)

    Please note this is a codelist of the relevant SNOMED code in the ECDS restricted reference set - there are other SNOMED codes for Bell's palsy which would be relevant in data sources using the full SNOMED dictionary
