SNOMED CT Delta Refset Descriptor Reference Set
This dataset describes the Delta Refset Descriptor Reference Set of SNOMED CT (SNOMED Clinical Terminology, referred to as Release Format 2 (RF2). The US Edition of SNOMED CT is the official source of SNOMED CT for use in US healthcare systems. The US Edition is a standalone release that combines the content of both the US Extension and the International release of SNOMED CT.

Description
SNOMED CT (SNOMED Clinical Terminology) provides a common language that assists with the electronic exchange of clinical health information. It enables a consistent way of indexing, storing, retrieving, and aggregating clinical data across specialties and sites of care. SNOMED CT Can be mapped to other coding systems, such as ICD-10, which helps facilitate semantic interoperability.
A Delta release contains only those component versions created, inactivated or changed since the previous release. The ‘Delta’ release is much smaller than a ‘Full’ release and is ideal for updating a ‘Full’ release of the previous version. Adding a ‘Delta’ release to the previous version’s ‘Full’ release will update the installation to a ‘Full’ release of the current Version.
The September 2019 SNOMED CT United States (US) Edition release includes an updated SNOMED CT to ICD-10-CM mapping reference with over 123,000 SNOMED CT source concepts mapped to ICD-10-CM targets. Please note that no new US-specific concepts were added in this release.

Data Fields
Name | Description | Type | Constraints |
---|---|---|---|
Reference_Set_Member_Id | A field, uniquely identifying this reference set member. Different versions of a reference set member share the same ID but have different Effective_Date. This allows a reference set member to be modified or made inactive (i.e. removed from the active set) at a specified time. | string | required : 1 |
Effective_Date | The inclusive date at which this version of the identified reference set member became the current version. | date | required : 1 |
Is_Active | The state of the identified reference set member as at the specified Effective_Date. If active= true, the reference set member is part of the current version of the set, if active=false, the reference set member is not part of the current version of the set. | boolean | required : 1 |
Module_Id | Identifies the SNOMED CT module that contains this reference set member as at the specified Effective_Date. | integer | level : Nominalrequired : 1 |
Refset_Id | Identifies the reference set to which this reference set member belongs. | integer | level : Nominalrequired : 1 |
Referenced_Component_Id | The identifier of the source component of the association. | integer | level : Nominalrequired : 1 |
Attribute_Description | Specifies the name of an attribute that is used in the reference set to which this descriptor applies. | integer | level : Nominalrequired : 1 |
Attribute_Type | Specifies the data type of this attribute in the reference set to which this descriptor applies. | integer | level : Nominalrequired : 1 |
Attribute_Order | Specifies the position of this attribute in the reference set to which this descriptor applies. A zero value identifies the Referenced_Component_Id within the reference set. Other values specify additional attributes by its position relative to the Referenced_Component_Id. Within a particular descriptor, attributeOrder values for a particular Referenced_Component_Id must be contiguous. An unsigned integer, providing ordering for the additional attributes extending the reference set. | integer | level : Nominalrequired : 1 |
