March 2019 US Edition of SNOMED CT Release Available

March 2019 US Edition of SNOMED CT Release Available. NLM Tech Bull. 2019 Mar-Apr;(427):b3.

The National Library of Medicine (NLM) is pleased to announce the March 2019 SNOMED CT United States (US) Edition release is available for download by UMLS Licensees.

In addition to 410 new concepts specific for the US, the March 2019 SNOMED CT US Edition also contains all of the content from the January 2019 SNOMED CT International Edition. This 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.

To download the release, you must have a UMLS Terminology Services login and agree to the UMLS Metathesaurus License. To learn more about the license and to sign up for an account, please see the Licensing SNOMED CT page for additional information.

Please note: To continue to align with the SNOMED CT International Edition, the US Edition will implement the following file changes starting with the September 2019 US Edition. These changes will allow for the continued efforts towards having a zip file including only RF2 data with additional supplemental documentation and artifacts available separately.

Deprecation of the Documentation folder

• This aligns with the SNOMED CT International Edition release package which no longer includes a Documentation file.

Deprecation of the doc_Icd10MapTechnicalGuideExemplars_[date].xlsx file

• This follows the decision by SNOMED International, first announced with the July 2018 International Edition (see 3.3.4 - Deprecation of the Technical Guide Exemplars document from the International Edition package). Going forward, the file will be available from SNOMED International.

Removal of SNOMED CT to ICD-10-CM documentation and resources from the US Edition download

• The SNOMED CT to ICD-10-CM documentation and resources will be made available alongside the US Edition of SNOMED CT as a bundled download - SNOMED_CT_to_ICD-10-CM_Resources_YYYYMMDD.zip. The following resources will be updated for each release and bundled together and made available with each new US Edition release:
  • doc_Icd10cmMapReleaseNotes_Current-en-US_US1000124_YYYYMMDD.pdf (will be available as an online resource and in the download)
  • doc_Icd10cmMapTechnicalGuideExemplars_Current-en-US_US1000124_YYYYMMDD.xlsx
  • doc_Icd10cmMapTechnicalSpecifications_Current-en-US_US1000124_YYYYMMDD.pdf (will be available as an online resource and in the download)
  • tls_Icd10cmHumanReadableMap_US1000124_YYYYMMDD.tsv
