Four new pages were published on the WHO’s main website on 17 May – the revised Timeline for ICD-11, the announcement of an Alpha Draft browser, a Registration form and a Caveat. Yesterday, I posted the revised ICD-11 Revision Timeline.

What can be seen for PVFS, (B)ME and CFS in the public Alpha Draft?

For the Alpha browser, go to this page:


Here it states:

The International Classification of Diseases 11th Revision is due by 2015

ICD is the international standard to measure health & health services

• Mortality statistics
• Morbidity statistics
• Health care costs
• Progress towards the Millenium Development Goals
• Research

– Alpha draft is updated daily as the work progresses
– It is intended to show the new features to stakeholders early
– Commenting will be available in July 2011

The link for the alpha browser is:


This is the link to a page for “Caveats”

ICD-11 Alpha Draft Caveats

ICD-11 alpha draft is:

• Incomplete
• May contain errors, omissions or imperfections
• The work in different chapters are at different stages
• The alpha drafting work is going on by the WHO, Revision Steering Group and Topic Advisory Groups
• The alpha draft is going to be updated on a daily basis
• The alpha draft is NOT TO BE USED for CODING at this stage
• The alpha draft has not yet been approved by the Topic Advisory Groups, Revision Steering Group or WHO

Click here to access the public Alpha Draft browser

Poke around and open the Parent and Child categories and the Tabs – you cannot edit or break anything.

This new interface is not as detailed or as easy to navigate as the software version of the iCAT collaborative drafting platform that was in the public domain up until November, last year. Less information is visible, for example, some of the paramenter tabs, including “Definitions”. (Compare with what could be seen in this iCAT screenshot from last June.)

This is a public draft and another platform is being used by ICD Revision for ongoing drafting. The public draft will be updated as the work of the various Topic Advisory Groups and working groups progresses. ICD Revision has not reached its targets for the generation of content and population of “Content Model” fields across all chapters and this draft is not as far forward as ICD Revision had projected for a May 2011 release.

Though viewable now, the Alpha drafting browser is not planned to be open for public comment until July, this year. It’s not yet clear which classes of public stakeholder will be able to participate in the drafting process, come July, or to what extent.

If you are interested in the proposed public comment, interaction and input processes for the Alpha and Beta drafting stages, see this DSM-5 and ICD-11 Watch post for meeting presentation slides.


First a caveat: It had been anticipated that a Beta drafting platform would be released in May, this year. WHO has cited lack of content and underdeveloped software for delaying the launch of a Beta drafting platform.

This public version of an Alpha drafting platform is a “work in progress”; not all disease and disorder categories may have been entered into the draft and proposed textual content is in the process of being authored and reviewed by the various Topic Advisory Groups, ICD Revision Steering Group and external peer reviewers.

From what can be seen, today, 19 May:

06L00 Chronic fatigue syndrome

is proposed to be coded within Chapter 6 Diseases of the nervous system (the Neurology chapter), as an ICD Title category, under the Parent class, 06L Other disorders of the nervous system.

Benign myalgic encephalomyelitis is specified as an Inclusion to 06L00 Chronic fatigue syndrome.

“Causal mechanisms” for 06L00 Chronic fatigue syndrome are cited as “Virus (organism)”.

The relationship between ICD Title category 06L00 Chronic fatigue syndrome and Inclusion term Benign myalgic encephalomyelitis is not yet specified, ie whether for ICD-11, “Benign myalgic encephalomyelitis” is proposed to be specified as a Synonym , Subclass or other relationship to “06L00 Chronic fatigue syndrome”.

Many categories within the draft are waiting for their Inclusion terms to be specified, not just the three terms of interest to us.

For explanation of Inclusions and other “Content Model” parameter terms, see: iCAT Glossary or the key ICD-11 Content Model document.

6 Inclusions

Details: Inclusion terms appear in the tabular list [Ed: ICD Volume 1] of the traditional print version and show users that entities are included in the relevant concept. All of the ICD-10 inclusion terms have been imported and accessible in the iCat. These are either synonyms of the category titles or subclasses which are not represented in the classification hierarchy. Since we have synonyms as a separate entity in our ICD-11 content model, the new synonyms suggested by the users should go into the synonyms section. In the future, iCat will provide a mechanism to identify whether an inclusion is a synonym or a subclass.”


What is the proposed relationship between PVFS and CFS?

Postviral fatigue syndrome is not accounted for in the “Foundations” or “Linearizations > Morbidity” listings.

In ICD-10, Postviral fatigue syndrome is an ICD Title category under G93 Other disorders of brain. I cannot confirm, but it may be that due to the hierarchy  change, “Postviral fatigue syndrome” is proposed to be subsumed under “06L00 Chronic fatigue syndrome” with “06L00 Chronic fatigue syndrome” becoming the ICD Title category, because “G93.3 Postviral fatigue syndrome” has lost its ICD-10 Parent category.

At the moment, there is not sufficient information displaying to determine what the intention is. Last June, I requested a clarification from Dr Raad Shakir, chair of Topic Advisory Group for Neurology, but no clarification has been forthcoming.

In the iCAT initial drafting platform, last November, where “Postviral fatigue syndrome” was referenced within a “Category Note” and specified as an Exclusion to Chapter 5 and Chapter 18,  it was referenced as:

“G93.3 Postviral fatigue syndrome -> Gj92 Chronic fatigue syndrome”

[“Note: Gj92” is a “Sorting label” assigned for the initial Alpha drafting process, not an eventual ICD-11 code.]


“Change history” note from May 2010

In ICD-10, “Postviral fatigue syndrome” is a Title code at G93.3 under Parent category “G93 Other disorders of brain”. “Benign myalgic encephalomyelitis” sits under “G93.3 Postviral fatigue syndrome” (relationship unspecified).

As previously reported, an iCAT “Change history” note, dated 1 May 2010, records a “Change in hierarchy for class: G93.3 Postviral fatigue syndrome because its parent category (G93 Other disorders of brain) is removed.”

This would leaves the existing ICD-10 G93.3 Title category, “Postviral fatigue syndrome” and “Benign myalgic encephalomyelitis” that sits beneath it, and also the G93.3 index entry for Chronic fatigue syndrome with no parent category.

Note that the removal of the parent “G93 Other disorders of brain” affects many other categories also classified under G93 in ICD-10 which have also been assigned new parents under the reorganization of Chapter 6 (VI).

No Exclusions have been specified yet for “06L00 Chronic fatigue syndrome”.

“Postviral fatigue syndrome” is specified as an Exclusion to the following ICD-11 chapters:

Chapter 5 “05E06 Other neurotic disorders > 05E06.00 Neurasthenia”
Chapter 18 “18GF General symptoms and signs > 18F03 Malaise and fatigue.”

(Chapter 18 is the “R code” chapter of ICD-10; ICD-10-CM proposes to retain CFS under R53 Malaise and fatigue at R53.82 Chronic fatigue, unspecified, as “Chronic fatigue syndrome NOS”, with the Exclusion: Postviral fatigue syndrome G93.3.)

Go here for ICD-11 Chapter 5 “Neurotic, stress-related and somatoform disorders” > Somatoform Disorders:


Go here for ICD-11 Chapter 18 “Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified”:



Congruency with DSM-5 proposals for revision of DSM-IV “Somatoform Disorders”

There is no obvious mirroring of the radical proposals currently being put forward by the DSM-5 Somatic Symptom Disorders Work Group to rename “Somatoform Disorders” to “Somatic Symptom Disorders” and combine a number of existing somatoform categories under a new rubric, “Complex Somatic Symptom Disorder”.


Registering for involvement

There is a Registration form here

This form appears to be aimed at recruiting medical health professionals for putting their names down to be contacted at some point to “Make comments; Make proposals to change ICD categories; Participate in field trials; Assist in translating“. It’s not clear whether or at what point in the Alpha/Beta drafting processes involvement might be extended to non professional stakeholders.
