 ## What is a codelist?
 
-Clinical codes, terminology systems, and codelists play a foundational role in structuring healthcare data within electronic health records (EHRs), enabling consistent recording, analysis, and research. Systems like 
-SNOMED CT, ICD-10, and dm+d provide standardised ways to represent clinical concepts, from diagnoses to prescriptions, across diverse healthcare settings.
