Content Request Service
SNOMED International coordinates requests for additions or changes to SNOMED CT through its Members' National Release Centers (NRCs). For more information about the processes in each country/territory, please access the relevant Member page.
​
Members' NRCs and other authorized users submit requests for additions or changes via the SNOMED CT Content Request Service (CRS). Requests that meet inclusion criteria for the International Release are addressed by SNOMED International staff. If a request is declined, a reason and explanation is provided to the requester, who may choose to appeal the decision to the Head of Terminology.
