The Standardisation Committee for Care Information approved the ICD-10 5th Edition for NHS implementation on 01 April 2016.

The Information Standards Notice describes the mandate.

In the ICD-10 4th Edition, the morphology of neoplasms, referenced in Volumes 1-3, were based on an earlier version of ICD-O; the second edition (ICD-O-2).

The ICD-O-2 morphology codes are not updated by the World Health Organization (WHO) and therefore are inconsistent with the current edition; ICD-O-3. To address the anomaly, the WHO has removed all morphology codes from Volumes 1-3 of the 5th Edition. 

Further information can be found in the Removal of Morphology Codes from ICD-10 5th Edition document.

Other updates were minor and reflected:

• latest clinical knowledge
• better indexing of conditions
• help with coding of diagnostic information

A number of errors have been identified in the printed ICD-10 5th Edition volumes by the WHO. As a result, we have compiled a single errata list which contains all changes that must be made in the printed ICD-10 5th Edition books. This can be found in the NHS ICD-10 5th Edition Errata within the ICD-10 and OPCS-4 Classifications Content Changes document.

A number of these errors are also replicated in the ICD-10 5th Edition eVersion, therefore we have a shared set of replica notes available on our Classifications Browser and eVersions page.

The ICD-10 and OPCS-4 Classifications Content Changes document also contains the changes that must be made to the ICD-10 5th Edition books; to the fourth character codes in the following categories:

• W26 Contact with other sharp objects
• X34 Victim of earthquake
• X59 Exposure of unspecified factor

Codes in categories U06.- Emergency use of U06 and U07.- Emergency use of U07 must only be used when specifically instructed by the Terminology and Classifications Delivery Service under direction from the WHO (ICD-10 National Clinical Coding Standard DCS.XXII.3: Emergency use codes (U06 and U07)).

There are now a number of codes within these categories that have been designated for use for Zika Virus (U06.9), Vaping (U07.0) and COVID-19 (U07.1-U07.5).

The codes within categories U06 and U07 are available within the ICD-10 5^th Edition Codes and Titles file and the WHO ICD-10 Volume 1 Tabular List but their descriptions remain as ‘Emergency use of’ as it would be too great a burden on users to issue an update to the files.

To assist users of the eVersion, we have created a set of shared notes reflecting the code descriptions of the codes designated for emergency use within categories U06 and U07 that can be imported into the eVersion. These are available on our Classifications Browser and eVersions page.

For more information on the emergency codes in categories U06 and U07 see the following within the ICD-10 National Clinical Coding Standards ICD-10 5^th Edition Reference Book:

• COVID-19 National Clinical Coding Standards and Guidance
• DCS.I.5: Zika virus
• DCS.XXII.4: Vaping related disorder (U07.0)

The ICD-10 5th Edition books are available to order from The Stationery Office (TSO) website.
