Regenstrief Institute and SNOMED International are very pleased to announce that the March 2017 Beta Edition LOINC/SNOMED CT Expression Association and Map Sets - Technology Preview is now available.

The Technology Preview files were generated as part of the cooperative agreement signed between Regenstrief Institute and SNOMED International (formerly IHTSDO) in July 2013. (Read more about the collaboration).
The agreement details how SNOMED CT and LOINC will be linked through:
- a map of LOINC terms to post-coordinated SNOMED CT expressions
- a map of LOINC parts to SNOMED concepts
- a map between LOINC terms and existing pre-coordinated SNOMED concepts
- LOINC Answer sets mapped to SNOMED codes; and
- addition of new content in either terminology.
This Technology Preview (draft mapping) is based on the 20170131 version of the SNOMED CT International release and Version 2.58 of LOINC released December 2016. The Technology Preview contains two main sets. The first is the LOINC Term to SNOMED Expression Reference Set. The LOINC Term to SNOMED Expression Reference Set contains 21971 active LOINC Terms associated with post-coordinated SNOMED CT expressions. This set covers the majority of the LOINC Top 2000 content. The second is the LOINC Part to SNOMED Reference Set that consists of 6629 LOINC Parts (LP) mapped to one or more SNOMED concepts.
The RF2 package contains two content files: a LOINC Term to SNOMED Expression Reference Set and a LOINC Part to SNOMED Reference Set. For each reference set it contains full release, snapshot, and delta files.
Feedback on this Beta release is requested during a short time frame for the main purpose of determining fitness of this product for Production release anticipated around the time of (but not with) the July 2017 International Release of SNOMED CT. Given the short turnaround period, feedback on any content errors or issues will be addressed in a subsequent Production release following the initial Production release. SNOMED International requests that you provide feedback by 14 April 2017. You can submit feedback on the SNOMED International Confluence site.
