December 14, 2011 Influenza A (H1N1) [swine flu]
The NHS Classifications Service has been closely following the deliberations of the World Health Organisation regarding the classification of Swine Flu in ICD-10.
For consistency within the UK NHS, we are providing clarification on how to classify this disease within the current NHS Information Standard ICD-10 (2000 reprint version).
The appropriate ICD-10 code assignment for this disease, where no manifestations have been identified, is J10.1 Influenza with other respiratory manifestations, influenza virus identified. This code is arrived at by use of the ICD-10 alphabetical index and the full four step coding process:
Swine flu
Index trail for Influenza:
Influenza (specific virus not identified) J11.1
- virus identified J10.1
Tabular List entry:
J10.1 Influenza with other respiratory manifestations, Influenza virus identified
The correct ICD-10 code to assign is J10.1 Influenza with other respiratory manifestations, Influenza virus identified.
If other specific manifestations of the influenza are identified, the whole of ICD-10 category J10.- Influenza due to identified influenza virus, should be considered where appropriate.
