SNOMED CT to ICD-10-CM Human Readable Cross Map

$179 / year

This dataset contains the human readable form of the SNOMED CT to ICD-10-CM cross map. The Map can be used in real-time by the healthcare providers and by coding professionals for retrospective coding purposes.


SNOMED CT is considered to be the most comprehensive, multilingual clinical healthcare terminology in the world. It is designed for use in clinical documentation in the Electronic Health Record (EHR). The purpose of the SNOMED CT to ICD-10-CM map (herein referred to as “the Map”) is to support semi-automated generation of ICD-10-CM codes from clinical data encoded in SNOMED CT for reimbursement and statistical purposes.

The direction of the Map is from SNOMED CT (source) to ICD-10-CM (target). All pre-coordinated SNOMED CT concepts that are appropriate for use in a problem list (about a third of all active SNOMED CT concepts) are potentially within scope for the map. Initially, a smaller subset of frequently used SNOMED CT concepts will be mapped. Not all ICD-10-CM codes will appear as targets. It is expected that frequently occurring ICD-10-CM codes will be covered in the initial phase. This can only be verified when real-life usage statistics of ICD-10-CM codes are available. Because of the difference in granularity of the two terminologies, some ICD-10-CM codes will not have SNOMED CT correspondents (e.g. concepts with laterality or episode of care information). Full representation of these ICD-10-CM codes will require post-coordination in SNOMED CT, which is not included in this Map.

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.
