NHS Digital is responsible for the UK management of SNOMED CT, the Read codes and other products to support the implementation of terminology including useful tools and derivative terminology products. NHS Digital maintains the NHS Dictionary of Medicines and Devices (dm+d) in partnership with the NHS Business Service Authority.
As part of the national strategy to move to a single terminology across health and care, NHS Digital is in the process of withdrawing the Read codes. The Standardisation Committee for Care gave notice in December 2014 of this planned withdrawal. Further details can be found on the Read webpage.
