Why primary care needs to migrate to SNOMED CT

Two versions of clinical codes (Read v2 and CTV3) currently exist in General Practice. Not all GP systems use the same coding system.

Parts of the Read code vocabulary are full and new codes have been allocated to unrelated areas. This makes analysis more difficult. 

The NHS needs a single clinical terminology, for clinical data to be exchanged accurately and consistently across all care settings. This will allow better patient care and improve how clinical data can be analysed and reported on.

SNOMED CT is an international clinical terminology. It will allow the UK to take part in more effective research and analysis of health information, to support national and global health care improvements.

When SNOMED CT is being implemented

SNOMED CT will go live in general practice care in a phased approach from April 2018. 

The phase include:

  • Behind the scenes changes
  • User facing changes

The deployment rollout will commence with pilot sites for the four principal clinical system suppliers, EMIS, TPP, Vision and Microtest.

More detail is provided in the suppliers plans section of the project Delen website. Please note this will be updated regularly to reflect current progress and details provided by suppliers.

NHS Digital will communicate updates on supplier milestones as they occur using the Delen website news feed.  


The timeline below shows the high-level milestones.

How SNOMED CT is being implemented

NHS Digital is supporting suppliers and primary care end data users during the transition, with implementation guidance and a range of  guidance and resources including publications, training and forums

A subset of SNOMED CT is available that reflects the current content of Read Codes. This will enable both SNOMED CT and Read Codes to be held in the clinical system during the transition (referred to as dual coding). This approach will mean existing searches, protocols and templates can continue to be used for a period of time after the system has switched to SNOMED CT for data entry.

Education and training

Suppliers of the clinical system will provide user system training, with their preferred training tools. Any queries should be directed to the GP system supplier.

NHS Digital provides training to help users learn more about SNOMED CT and the transition. Please:
