Notice of changes to the Content Request Service Service Level Agreement

January 22, 2019

The SNOMED CT Content Request Service (CRS) is a tool that enables users to submit requested changes to SNOMED CT content. Content submissions must adhere to established guidelines published on the organization’s Confluence website. The organization also publishes content development information for documentation release notes, early visibility into changes, and other areas that may impact your request. 

Changes to service level agreements (SLA) are initiated as a way to manage the organization’s resource load as well as preserve balance among content submitters. Further, changes to the current SLA are due to the need to progress the multi-year Quality Initiative underway. 

Changes to the SLA are in effect as of January 17th, 2019 and include: 

Request Commitment:Change:

  • Reduced from 2500 for better resource planning and managementA minimum total of 1500 separate requests within set timelines and meeting submission criteria will be added to the next release, provided the request is not marked for clarification, appeal or rejected. This change from 2500 to 1500 is being implemented to better assist the organization understand our resource allocation supporting content requests.

Request Balance:Change:

  • Reworded for better claritySNOMED International also reserves the right to assess the number of submissions made per country per release to create balance of submissions and fairness in equal resolution of requests.


  • Reworded for better clarityA single request may not exceed 150 concept additions or changes.  No further request batches of the “same type” may be submitted in a single editing cycle in order to circumvent the Bulk submission process. Once a total of 150 additions or changes have been reached, no further requests of the same type will be accepted during the release cycle. Slight overages of the 150 will be considered on a case by case basis. 

These changes will predominantly affect Members (National Release Centres) and other authorized submitters including collaboration partners, clinical reference groups, etc. and take effect January 17, 2019.
