SNOMED CT Snapshot Description Type Reference Set
Description format reference set is a C-I (component – integer) reference set which is used to specify the length and format of the terms in descriptions of this description type. This dataset describes the Release File structure of SNOMED CT, referred to as Release Format 2 (RF2) of the US Edition of SNOMED CT which is the official source of SNOMED CT for use in US healthcare systems.

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 Snapshot release contains the most recent version of every component released up to the time of the snapshot. The version of each component contained in a snapshot is the most recent version of that component at the release time. The ‘Snapshot’ release is useful for a simple installation but does not provide a history or retrospective view of the terminology. There are valid use cases for each Release Type. Each International release will incorporate all three of these Release Types, allowing users to choose the most appropriate format.
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.

|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||Specifies the description type to which this format applies.||integer||level : Nominalrequired : 1|
|Description_Format||Specifies the format of terms in descriptions of this description type.||integer||level : Nominalrequired : 1|
