ICD-11 is the next version of the International Classification of Diseases and represents the 11th revision of Bertillon’s original classification.

There is a large amount of material on ICD-11 at the WHO website. In the previous posts we have looked at the discussion about harmonisation of SNOMED CT® and ICD-11.

The most recent conference on ICD-11 was held in Japan and the report can be found here. The immense complexity of the revision is evident from some of the accompanying figures:

At the structural level, 2016 saw nearly 11,000 parenting changes (mostly the addition of multiple parents), 6163 entity titles were edited for completeness and accuracy,4255 changes were made to the shoreline (e.g. coding granularity), and 2200 changes were made to the different groupings in the hierarchy
A beta version of the online ICD-11 browser can be found here and there are a number of important caveats included on that page (e.g. not yet approved by WHO and not to be used in coding except for field trials).
