Refset Descriptor Reference Set specifies the structure of reference sets.

Complexity

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 Full release contains every version of every component that has ever been released prior to or in the specified Edition. This release provides a full historical record and can be used to obtain views of the state of any component at any point in time since its first release.

In addition to 623 new concepts specific for the US, the September 2018 SNOMED CT US Edition also contains all of the content from the July 2018 SNOMED CT International Edition. Approximately 543 requests for terminology additions and updates were submitted via the US Content Request System (US CRS) to support US clinical health information data exchange. This latest version of the US Edition also includes the SNOMED CT to ICD-10-CM reference set, with over 123,000 SNOMED CT source concepts mapped to ICD-10-CM targets.

NameDescriptionTypeConstraints
Reference_Set_Member_IdA 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.stringrequired : 1
Effective_DateThe inclusive date at which this version of the identified reference set member became the current version.daterequired : 1
Is_ActiveThe 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.booleanrequired : 1
Module_IdIdentifies the SNOMED CT module that contains this reference set member as at the specified Effective_Date.integerrequired : 1 level : Nominal
Refset_IdIdentifies the reference set to which this reference set member belongs.integerrequired : 1 level : Nominal
Referenced_Component_IdThe identifier of the source component of the association.integerrequired : 1 level : Nominal
Attribute_DescriptionSpecifies the name of an attribute that is used in the reference set to which this descriptor applies.integerrequired : 1 level : Nominal
Attribute_TypeSpecifies the data type of this attribute in the reference set to which this descriptor applies.integerrequired : 1 level : Nominal
Attribute_OrderSpecifies 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 an 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 an ordering for the additional attributes extending the reference set.integerrequired : 1 level : Nominal
