ICD-11 Implementation

This page contains details on the transition of NI Death Statistics from ICD-10 to ICD-11 death coding.  The Vital Statistics Team will be implementing this change and will be posting updates periodically on this page.

ICD-10 Death Coding in Northern Ireland is Changing       

 What is ICD Coding?

Coding for cause of death in Northern Ireland is carried out according to the World Health Organisation’s (WHO) International Classification of Diseases, tenth revision (ICD –10).  This classification allows the systematic recording, analysis, interpretation and international comparison of mortality data. The latest version of the ICD, ICD-11, was adopted by the 72nd World Health Assembly in 2019 and came into effect on 1 January 2022. NISRA, along with the Office for National Statistics (ONS) will be implementing ICD-11 into its mortality statistics over the next three to four years, in keeping with the WHO’s estimated transition period.  This move allows for mortality statistics in Northern Ireland to continue to be internationally comparable, follows international best practice, addresses gaps in the current ICD-10 and incorporates medical updates, discoveries and changes in thinking.

When is this change happening?

The changeover is currently expected to take place in January 2027 in line with England and Wales and Scotland.

How will users be kept up to date?

The NISRA Vital Statistics Unit will be updating users on this webpage, via their newsletter and periodic email updates to users.

What do I need to do?

Users should start to consider how changes in ICD coding may impact them. The easiest way to be prepared is to be added to our mailing list for ICD-11 as the Vital Statistics Unit will be issuing updates periodically and engaging with users. You can sign up for the mailing list by emailing the Vital Statistics Unit at: demography@nisra.gov.uk
