Legally restricted patient confidential reference data
PBCL Read Code to SNOMED Code Translation Table
Primary Care Domain reference sets
SNOMED CT UK Query Table and History Substitution Table
The technical preview code list was originally drafted to support a refresh of the ISB 1572 Sensitive Data standards and for no other purpose.
The legal basis for patient identifiable data and sensitive information changed with the introduction of the Health and Social Care Act 2012. However, the legal and policy context and interpretation for sensitive and/or legally restricted data has not been fully established due to the changes in legislation since the original standard was released.
As a result, this supporting code list has remained static since April 2016. NHS Digital will update the codes once an updated policy and instruction is provided by our commissioners.
Releases of this item contain products intended to support the GP Summary Care Record, Systems of Choice and Data Migration programmes. Specifically:
Releases also include experimental SNOMED CT Navigational Subsets by which simulacra of the Read Version 2 and Clinical Terms Version 3 taxonomies may be recreated as views on the full SNOMED CT content.
Read important information on the retirement of Read Version 2 and Clinical Terms Version 3.
Following consultation, the final release of the Read Version 2 to SNOMED CT mapping tables was April 2020. Releases of this item are now unmaintained static data.
Unscheduled releases may occur until April 2023, but only in order to resolve critical clinical safety issues.
Status: Deprecated
A set of map tables translating the Read Codes in the PBCL EDIFACT laboratory report message to SNOMED CT codes to support transmission, reception, storage and retrieval of primary care pathology results.
Status: Supported
Primary Care Domain reference sets are clusters of codes used within the business rules authored and maintained by NHS England's primary care domain.

From the first Primary Care Domain reference sets release that aligns with the June 2023 SNOMED CT UK Clinical releases (expected to be published by August 2023), all stated relationships will be inactivated and Owl Expressions will be published, to bring releases of this item in line with the SNOMED CT UK Clinical releases.
From the first Primary Care Domain reference sets release that aligns with the August 2023 SNOMED CT UK Clinical releases (expected to be published by October 2023), releases of this item will be published in 2 formats:
From 2024 the beta format will become the only published production format and the previous production format will be discontinued.
We recommend transitioning to consuming the beta format as soon as possible once it becomes available.
Mapping tables and guidance to enable historical data previously captured using an antecedent legacy version of SNOMED II, 3.x International or SNOMED RT to be migrated to SNOMED CT.
Expected use cases include, but are not limited to, histopathology laboratories and their Laboratory Information Management Systems and suppliers, and secondary users of histopathology data including Cancer Registries.
Status: Technology Preview
Releases of this item contain 2 related derivatives of the SNOMED CT UK Edition to aid the processing of inactive content within systems and data repositories.
The History Substitution Table provides a single table identifying valid substitutions for concepts that are now inactive, along with metadata about that substitution; it is computed using the historical relationships within the main SNOMED CT release but presented as a simpler look-up table.
The Query Table is an extension to a normal SNOMED CT transitive closure table, taking into account the History Substitutions Table and other data. It provides a mechanism to achieve optimal data retrieval, regardless of inactive and active concept status in data or query definitions. The Query Table is recommended as a mechanism for ensuring inactive content is still returned in searches, and is specifically recommended by the Joint GP IT Committee for use in primary care systems.
