Request Status Glossary

CRS Status
SIRS Status
DraftA request that has been started and saved but not yet submitted.Draft
NewAll submissions (excluding draft) are initially assigned a status of New.  A preliminary check will be carried out to ensure that the new request falls within the inclusion criteria and scope for the International Edition of SNOMED CT before the request will be progressed.


AcceptedFollowing initial review, each request is assigned to a member of the Content Team. A change to a status of  ‘Accepted’ does not mean that the request will be approved for inclusion in SNOMED CT.


& Accepted In Scope

Under AuthoringA member of the Content Team is actively evaluating the request.


In Inception

Where a new request aligns with an ongoing content project, the request will be placed into this status until editorial policy is available to support the requested change or addition. Content projects are intended to investigate issues or enhancements to both existing and future content for SNOMED CT. A process for understanding the problem and elaboration of a solution is undertaken in order to make improvements to existing content and clarify how content of a similar nature will be incorporated into SNOMED CT in the future. Depending upon the nature of the content project, this may be a longterm large-scale content project or a smaller project with a shorter timescale.

Awaiting policy

Clarification NeededWhere insufficient information is provided to proceed with a request, a member of the Content Team will incorporate questions to be resolved and change the status of the request to ‘Clarification Needed’. This will generate an email to the original requester. Where a request for clarification to a customer is not answered within 60 days from the date the clarification is generated, the request will be marked as rejected.

Clarification requested

ForwardedWhere a request is received that is not in scope for the International Edition of SNOMED CT, it may be suitable for a specific extension. The request may be marked as forwarded to denote that it has been handed over to another extension manager or National Release Center.


WithdrawnOnce submitted, a request cannot be deleted but can be "Withdrawn" by the original requestor.Withdrawn
In AppealWhere a request has been “Not Accepted”, the submitter may request a further review of the decision. The submitter can then place the request in “In Appeal” status. In these circumstances the decision will be reviewed and if necessary referred to the Head of Terminology for final disposition.Appeal
Appeal Rejected

After conclusion of the appropriate appeal process, where the outcome remains unchanged, this status will be applied.

Appeal Rejected

RejectedWhere a request has had a full review and is not considered to be in scope for SNOMED CT, or does not meet the criteria outlined in the Editorial Guide, or clarification about the request has not been received within 60 days it will be rejected.


Ready For Release

The requested change has been made and approved, however this status does not assure that the requested change will be included in the final release data.

CompletedA request status will be changed to "Completed" once the SNOMED CT International Edition, in which the request has been addressed, has been released.Completed

  1. Hi, 

    may I interpret the CRS status 'Completed' as that the requested new concept or the requested changes for a concept are included in the release? I'm asking this because I have 5 new/changed concepts in my CRS with status 'completed' but I can't find them in the int. browser, neither in the release files.

    Kind regards, Katrien

    1. Hi, Katrien Scheerlinck

      they are likely to have been completed for the incoming July 2018 release. If you would like to check, please send further detail to so that we can investigate further if necessary.
