SNOMED

SNOMED CT stands for Systematized Nomenclature of Medicine Clinical Terms. It is the standard clinical terminology for the NHS to support recording of clinical information, in a way that supports data management and analysis to support patient care, while enabling data extraction and data exchange. SNOMED CT provides a comprehensive set of clinical phrases or terms; this is called a terminology. SNOMED CT is much more than just a set of clinical phrases, for example it also includes groups with relationships between terms. It is the most comprehensive international terminology currently available and can be used across all care settings and all clinical domains.


Where SNOMED is used in the MHSDS

If the Data Item Name of a field ends in (SNOMED CT) then it must be provided in SNOMED. If the Data Item Name of a field ends in (CODED CLINICAL ENTRY) then it can be provided in SNOMED or ICD-10, and which one you use should be specified in the neighbouring field ending SCHEME IN USE. Please check the Technical Output Specification to understand what is required for each field.

For most SNOMED fields, we don’t provide a list of expected values. This is because by its nature, SNOMED is not expected to be a reference table of a small number of codes. It is supposed to be used at the point of care to record everything that a clinician writes in a patient’s notes.

However, there are certain cases where a list is provided: 

The SNOMED required to stop the clock for Children and Young People with Eating Disorders can be found in our quick guide to CYP ED Waiting Times.

Early Intervention in Psychosis Caseload measures (EIP69a and EIP69b) count referrals with SNOMED activity that is either NICE-concordant or any other SNOMED. The list of NICE-concordant SNOMED codes can be found in the script for these measures embedded in the metadata. For more information on EIP pathways and NICE-concordant treatment, see the document Implementing the early intervention in psychosis access and waiting time standard guidance. Still refer to the metadata for the most up to date SNOMED codes.

Mental Health Assessment Tools (tables MHS606, MHS607 and MHS608) and Cluster Tools (MHS802) must be provided in SNOMED, and these must be taken from the lists provided in the Technical Output Specification tabs ‘MH Assessment Scales’ and ‘Cluster Tools for MH’ respectively.
