This tool allows users to request, modify, or make additions to SNOMED CT. The USCRS is the SNOMED International content request system specific for user content requests for the US Edition of SNOMED CT.
The USCRS tool is important in the effort to support the development, enhancement, and distribution of clinically specific vocabularies to facilitate the exchange of clinical data and improve retrieval of health information. SNOMED CT is one of a suite of designated standards for use in U.S. Federal Government systems for the electronic exchange of clinical health information and is also a required standard in interoperability specifications of the U.S. Healthcare Information Technology Standards Panel.
Please go to US Edition SNOMED CT Content Request System (https://us-request.ihtsdotools.org/), which will then open the Welcome to SNOMED International page to enable log in. Once your login details are authenticated, the login process will automatically open your USCRS dashboard at the original address.
Please Note: The application is optimized for the Google Chrome browser - please do NOT use another browser (such as IE).
A SNOMED International account is needed to access CRS.
If you do not have an account, or find that your existing account does not have access to USCRS, please follow the instructions on our SNOMED International User Accounts page. The form on this page can be used to request a new account for USCRS access, and also to (including USCRS) if not yet granted to an existing account.

Users are able to create requests to add, modify or retire information in SNOMED CT including:
Creating a new Concept(s)
New Synonym(s)
Add Parent(s)
Modify Description(s)
All requests are treated as normal priority with the exception of data errors. Where a request points towards a possible error in SNOMED CT, the request will be prioritized for investigation.
There are three methods of creating requests for SNOMED Content: Simple Mode, Direct Mode, and Batch Mode. To learn more about these modes and help choosing the correct one see: Creating Requests.
A basic understanding of SNOMED CT content and structure is required, and each request must include a justification, or practical use case. Every request must also include an identifier that links to the current version of either International Edition of SNOMED CT or US Edition of SNOMED CT. Both are available from the National Library of Medicine to users with a UMLS Metathesaurus License.
Users may exist the system for later completion, validation, and submission.

Following 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.

Under Authoring
A member of the Content Team is actively evaluating the request.
Construction
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 ‘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
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.

Once submitted, a request cannot be deleted but can be "Withdrawn" by the original requestor.
