Current code usage data for SNOMED codes added to a GP patient record in England.
The following files show the number of times each listed SNOMED code was added to a GP patient record within the period 1 Aug to 31 July for the years available, aggregated at England level. The data is available in .txt and .xlsx formats.
Data does not show how many patients had each code added to their record. A patient could have one code added to their record multiple times throughout the year, therefore it is not possible to infer the number of patients with a particular code from this data or use the data to calculate disease prevalence.
Only valid SNOMED concepts are included and not all practices are included - please read the metadata prior to using this data.
Data prior to 2019 was originally submitted predominantly in READ V2 or CTV3. For the purposes of reporting these data have been mapped forward to their corresponding SNOMED codes. For further information on this please refer to the metadata file available from the SNOMED code usage 2011-12 to 2017-18 page below.
