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 Needed
Where 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 âClarification Neededâ. 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
Forwarded
Where 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.
