SNOMED CT Snapshot Module Dependency Reference Set to ICD-10-CM Map

$179 / year

This dataset is one of the three separate files that the ICD-10-CM MAP contains. Module Dependency reference set designates the versions of other SNOMED CT modules upon which this publication of the MAP depends. This dataset is an update of the SNOMED CT to ICD-10-CM Cross Map. The purpose of this update is to synchronize with the latest release of the US Edition of SNOMED CT by removing obsolete content.


The mapping in this dataset is identified by the refsetid 6011000124106. Module Dependency designates the versions of other SNOMED CT modules upon which this publication of the MAP depends.

SNOMED CT is an extensive clinical terminology that was formed by the merger, expansion, and restructuring of SNOMED RT (Reference Terminology) and the United Kingdom National Health Service (NHS) Clinical Terms (also known as the Read Codes). It is the most comprehensive clinical vocabulary available in English (or any language). SNOMED CT is concept-oriented and has an advanced structure that meets most accepted criteria for a well-formed, machine-readable terminology. It has been designated as a US standard for electronic health information exchange in Interoperability Specifications produced by the Healthcare Information Technology Standards Panel and has also been adopted for use by the US Federal Government, through the Consolidated Health Informatics (CHI) Initiative, for several clinical domains.

This cross map is a directed set of relationships from SNOMED CT source concepts to ICD-10-CM target classification codes. The SNOMED CT source domains for this mapping are limited to subtypes of 404684003 |clinical findings|, 272379006 |event| and 243796009 |situation with explicit context|.

This update of the map includes:
– 100,185 SNOMED CT source concepts including:
– 94,844 clinical findings
– 2,813 events
– 2,528 situations with explicit context
– 5,696 source concepts could not be assigned a map target due to issues of ambiguity or target scope
– A total of 168,810 map records, with a maximum of 23 map records per map group

Map_Record_IdA field, uniquely identifying the map category record.stringrequired : 1
Effective_TimeSpecifies the inclusive date at which this change becomes effective.daterequired : 1
Is_ActiveSpecifies whether the member’s state was active (=1) or inactive (=0) from the nominal release date specified by the effectiveTime field.booleanrequired : 1
Module_IdIdentifies the member version’s module. Set to a child of 900000000000443000|Module| within the metadata hierarchy.integerlevel : Nominal required : 1
Refset_IdSet to one of the children of the 447250001 |Complex map type| concept in the metadata hierarchy.integerlevel : Nominal required : 1
Referenced_Component_IdA reference to the module on which this module depends, a descendant of 900000000000443000|Module| in the metadata hierarchy.integerlevel : Nominal required : 1
Source_Effective_TimeThe effective time of the source module. This allows a specific module version to be selected as having a dependency. The Effective_Time must match exactly.daterequired : 1
Target_Effective_TimeThe effective time of the target module. This allows a specific module version to be selected as being the subject of a dependency. The Effective_Time must match exactly.daterequired : 1
