Update to Letter to key Revision personnel re Continued absence of the ICD-10 G93.3 terms from the ICD-11 Beta drafting platform

Post #324 Shortlink: http://wp.me/pKrrB-46A

Update at February 23, 2016: Since no proposals and rationales for the ICD-10 G93.3 legacy terms were released in September or December 2015, I contacted ICD’s Dr Robert Jakob, again. Dr Jakob told me on February 2, 2016 that “[ICD-11 Revsion is] still working on the extensive review and the conclusions.”

This report is an update to Post #322:

Continued absence of the ICD-10 G93.3 terms from the ICD-11 Beta drafting platform: Letter to key Revision personnel

Eight years into the revision process and stakeholders still don’t know how ICD Revision proposes to classify the ICD-10 G93.3 legacy terms for ICD-11.

In ICD-10, the (G93.3) Title term is Postviral fatigue syndrome; Benign myalgic encephalomyelitis is the Inclusion term under G93.3; Chronic fatigue syndrome is included in the Index only, and indexed to the G93.3 code [1].

By 2012, the public version of the ICD-11 Beta draft had the three terms listed as in the screenshot, below – still under the Diseases of the nervous system chapter, but with a change of relationship between the three terms.

At that point, Chronic fatigue syndrome was being proposed as a new ICD Title term; Benign myalgic encephalomyelitis* was specified as the Inclusion term (indicated in the draft by hover text over the asterisk which is not displaying in this screenshot).

Postviral fatigue syndrome, previously designated as Title code in ICD-10, was now located under Synonyms, in a list of alternative and historical terms imported from other terminology systems and health informatics sources, including two terms specific to Chapter 18: Symptoms, signs etc. of the U.S. ICD-10-CM clinical modification [4].


Source: ICD-11 Beta drafting platform, public version, July 25, 2012.


In early 2013, ICD Revision removed the entry for Chronic fatigue syndrome and its associated terms from the public version of the Beta draft; from that point on, none of the terms were accessible in any Linearization.

(In the version of the Beta that the public sees, there are no holding pens viewable for categories “Needing a decision to be made” and no tab for “Category Notes and Decisions” which might indicate the rationale for the temporary or permanent absence of a category from the draft.)

Although a Change History function was incorporated into the public Beta in March, no Change History is available for these terms. The Topic Advisory Group (TAG) for Neurology has published no progress reports on emerging proposals for scrutiny and discussion.

So for over 2 years, now, stakeholders have been unable to monitor evolving proposals for the classification of these G93.3 legacy entities within ICD-11. The continued absence of these terms hinders submission of comments and suggestions on proposed chapter location(s), parent classes, hierarchies, inclusions, exclusions, definitions or other Content Model descriptive text.


Request for release of information on current status of proposals

On June 8, I sent a letter to Bedirhan Üstün (WHO/ICD Revision Coordinator), Cc’d to key ICD Revision personnel and the recently assembled ICD Revision Project Management Team, requesting an update on the status of proposals for these terms and their restoration to the draft [5]. Read letter here

On Friday, June 19, Anneke Schmider (WHO Technical Officer, ICD Revision Project Manager) facilitated a conference call with myself and Dr Robert Jakob (WHO ICD classifications, ICD Revision Steering Group) in which Dr Jakob responded to my letter, having obtained a progress report from TAG Neurology.

NB: It was not the purpose of this discussion to advance my own views on how these terms should be represented within ICD-11 but to elicit clarifications on the current status of proposals.


Summary of main points from our discussion:

TAG Neurology retains responsibility for these three terms.

None of the sub-working groups that sit under TAG Neurology has specific responsibility for these terms.

TAG Neurology is still reviewing the literature and has yet to reach consensus about where to classify these terms within ICD-11.

Dr Jakob says he can be “crystal clear” that there is no proposal to classify the ICD-10 G93.3 legacy terms under the Mental and behavioural disorders chapter.


The ICD-11 principle of multiple parenting was discussed in general terms: multiple parenting allows the same disease to be expressed in two (or more) places in the ICD-11 linearizations. A disease or disorder category will be located under a primary parent class within one chapter but may also be searchable under a secondary (or tertiary) parent within another chapter, whilst retaining the code assigned in the primary location. (See ICD-11 Multiple parenting Slides 42-48)

Because TAG Neurology is still working towards consensus, Dr Jakob would not be drawn on the following:

whether relocating one or more of these terms from the Diseases of the nervous system to an alternative chapter(s) was under consideration;

whether retaining one or more of these terms within the Diseases of the nervous system chapter but secondary parenting under an alternative chapter(s) was under consideration;

what existing parent classes were being considered for locating these terms under;

whether the creation of any new parent classes was being considered for these terms;

whether any changes in the relationship between the three terms, as they had stood in the Beta draft in early 2013, have already been agreed or remain under consideration (ie any changes to which of the terms are identified as ICD Title terms, which are specified as Inclusion terms and which are listed as Synonyms).

which of the terms are proposed to be assigned a Definition and other Content Model descriptive text and where definition(s) would be sourced from.

It remains unclarified, therefore, whether ICD-11 intends to define CFS discretely from BME. Also unclarified: whether exclusions for these terms are proposed to be inserted under categories such as Bodily distress disorder; Fatigue [previously Malaise and fatigue in ICD-10]; and a proposed new Diseases of the nervous system parent term, Functional clinical forms of the nervous system (a proposal that TAG Mental Health opposes).

I have already submitted requests via the Proposal Mechanism that PVFS, BME and CFS are inserted under Exclusions to Bodily distress disorder, and Fatigue.


With regard to a date by which we might anticipate proposals being released:

The Beta draft was frozen on May 31, 2015. The Beta Comment facility is open and stakeholders can register to comment on the draft or submit formal proposals for changes and enhancements to proposals via the Proposals Mechanism. Another frozen release is expected in August. (But while TAG Neurology’s proposals remain absent from the Beta and unpublished elsewhere, stakeholders are in no position to comment on the TAG proposals or submit suggestions for modifications to TAG proposals.)

Dr Jakob says that in September 2015, ICD Revision plans to post various materials relating to the development process on the WHO/ICD website for public scrutiny, this to possibly include rationales, and documents relating to the abridged Primary Care version of ICD-11.

If TAG Neurology’s proposals for the G93.3 legacy terms are not ready for September release, then Dr Jakob projected their release towards the end of December 2015.

The target date for presentation of ICD-11 for World Health Assembly (WHA) approval is currently proposed for May 2018. There would be a period for public review and comment prior to presentation for adoption.

I will update on the status of proposals for these terms as soon as further information becomes available.

It is regrettable that stakeholders are little better informed than they were two years ago.


Bodily stress syndrome (S3DWG); Bodily stress syndrome (PCCG)

My longstanding concerns regarding the proposals of the WHO Working Group on Somatic Distress and Dissociative Disorders (S3DWG) for the revision of the ICD-10 Somatoform disorders and the alternative proposals of the ICD-11 Primary Care Consultation Group (PCCG) were beyond the scope of my letter to Dr Üstün and my discussions with Dr Jakob in response to that letter.

However, I advised Dr Jakob that my concerns around proposals for the S3DWG’s “Bodily distress disorder” and the Primary Care Consultation Group’s “Bodily stress syndrome” have been discussed with ICD Revision’s, Dr Geoffrey Reed, and in formal submissions via the Proposals Mechanism and Beta Comment facility for the consideration of TAG Mental Health [6][7].

Update: June 12, 2015: This situation is now being looked into by a member of the recently assembled ICD-11 Project Management team.

As previously posted:

Although the development process for ICD-11 has been in progress for eight years, it’s still not known how ICD Revision proposes to classify the ICD-10 G93.3 legacy terms.

On June 8, I sent a letter, via email, to WHO/ICD Revision, requesting a prompt resolution to this situation:

Re: Continued absence of the ICD-10 G93.3 legacy entities from the public version of the Beta drafting platform

Monday, June 8, 2015

Dear Dr Üstün,

At the end of May, a frozen release was posted for the ICD-11 Beta draft.

I remain extremely concerned that there are still no entries in the public Beta, within any linearization, for the three ICD-10 G93.3 legacy entities:

Postviral fatigue syndrome
Benign myalgic encephalomyelitis
Chronic fatigue syndrome

As you are aware, these three entities (plus a dozen or so synonym terms) were removed without explanation from the Diseases of the nervous system chapter of the public version of the Beta draft, in early 2013.

Consequently, for over 2 years, stakeholders throughout the world have been unable to view evolving proposals for the classification of these entities within ICD-11 or to scrutinise proposed chapter location, proposed hierarchies, proposed Definitions and other Content Model parameters.

It is very difficult to monitor, make comments or suggestions where terms are not represented within the draft.

A request submitted by me, in February, via the Proposal Mechanism, to restore these entities to the public Beta has produced no response.

While these three entities remain absent from the Beta draft, stakeholders are effectively disenfranchised from participating in the revision process.

Since the start of the revision process, in 2007, no progress reports, editorials or journal papers have been published on behalf of TAG Neurology discussing the work group’s deliberations for these specific entities.

Since early 2013, when the three entities were removed from the public Beta, there has been no information available, at all.

I am aware that in March 2014, enquiries had been made by English and Scottish Health Directorates and that WHO was jointly approached by several UK registered ME/CFS patient organizations and English parliamentarians. The WHO’s response, at that point, was that proposals for the classification of these terms was unresolved and that more time and more input from the work groups was required [1].

A year later, the need for clarification for current proposals remains unmet.

Given the level of concern amongst stakeholders, globally, would you please look into this matter?

Could you please expedite the restoring of these terms to the Beta draft, with a Change History, in order that the ICD-11 development process can be inclusive of the thousands of clinicians, researchers, allied health professionals, advocacy organizations and patients with a stakeholder interest in the classification of these terms.

If it is not possible to restore terms to the Beta while a freeze is in operation, could TAG Neurology be instructed to issue an immediate statement of intention for these terms, in the interim?

Many thanks in anticipation of a swift resolution.


Suzy Chapman

1 Correspondence, Scottish Health Directorate and WHO, March 2014, obtained under FOI.

Background to this letter:

In ICD-10 Version 2015:

Postviral fatigue syndrome is coded in Chapter VI: Diseases of the nervous system (the Neurology chapter), at code G93.3, under parent class G93 Other disorders of brain (view here).

Benign myalgic encephalomyelitis is the inclusion term to Postviral fatigue syndrome and assigned the G93.3 code.

Chronic fatigue syndrome is not included in ICD-10 Volume 1: The Tabular List but is indexed to G93.3 in ICD-10: Volume 3: The Alphabetical Index.

(The orange symbol denotes an Index term)


Proposals for ICD-11

In May 2010, a change to the hierarchical relationship between the three terms had been proposed. Whereas Postviral fatigue syndrome had been the Title category term for ICD-10, Chronic fatigue syndrome was proposed as the Title category term for ICD-11.

As part of a substantive reorganization of the Neurology chapter, the parent class, G93 Other disorders of brain (under which the ICD-10 categories G93.0 thru G93.9 were located), is proposed to be retired for ICD-11.

This has meant that the terms that sat under the G93 parent class for ICD-10 would need to be relocated under alternative parent classes for ICD-11 or have new parent classes created for them.

In July 2012, the public version of the ICD-11 Beta drafting platform had stood as in my screenshot, below.

It’s not evident in my screenshot, but the asterisk at the end of Benign myalgic encephalomyelitis displayed a hover text denoting its specification as the Inclusion term to ICD Title term, Chronic fatigue syndrome.

Also not evident in this cropped screenshot is the listing of Postviral fatigue syndrome under Synonyms.

At this point, around 14 historical or alternative terms were listed under Synonyms. These additional uncoded for terms, which had included the ICD-10-CM R53.82 terms, chronic fatigue, unspecified and chronic fatigue syndrome nos, had been scraped from other classification and EMR systems as part of the Beta drafting process :


Source: ICD-11 Beta drafting platform, July 25, 2012.

In November 2012, ICD Revision inserted a scrappy Definition for Chronic fatigue syndrome (this replaced an earlier draft ICD-11 Beta Definition). I have sourced this draft Definition to an internal ICD Revision/Stanford Protege document (line 1983):

Chronic fatigue syndrome is characterized by extreme chronic fatigue of an indeterminate cause, which is disabling andt [sic] does not improve with rest and that is exacerbated by physical or mental activity.

The “Selected Cause” sub linearization was later removed from the public Beta draft and some of the terms that had been listed under it were restored to the Neurology chapter and to other chapters. But Title term, Chronic fatigue syndrome, its Inclusion term and its list of Synonyms were not restored to any chapter.

Since February 2013, no listing can be found in any chapter of the public version of the Beta draft, under any linearization, for any of the terms, Postviral fatigue syndrome, Benign myalgic encephalomyelitis or Chronic fatigue syndrome, either as uniquely coded for ICD Title terms, or as Inclusion terms or as Synonyms to Title terms, or listed in the ICD-11 Beta Index.

So currently, there is no information within the Beta draft for proposals for these three terms.

The public version of the Beta drafting platform displays no editing “Change History” or “Category Notes” for these terms and their continued absence from the draft is hampering professional and public stakeholder scrutiny, discourse and comment.

This is not acceptable for any disease category, given that ICD Revision is promoted by WHO’s, Bedirhan Üstün, as an open and transparent process that is inclusive of all classes of stakeholder. The recent external review of the revision process has called for greater transparency [1].

Since June 2013, my repeated requests for an explanation for the absence of these three terms from the Beta draft and for ICD Revision’s intentions for these terms were ignored by ICD Revision until July 2014, when a response was forthcoming from ICD Revision’s, Dr Geoffrey Reed.

It is understood that Annette Brooke MP also received a response, in July 2014, from WHO’s, Dr Robert Jakob, in respect of the joint organizations’ letter of March 18, for which Ms Brooke had been a co-signatory [2].

What clarifications have been given?

WHO and ICD Revision’s, Dr Geoffrey Reed (Senior Project Officer, Revision of Mental and behavioural disorders), have said that there has been no proposal and no intention to include ME or other conditions such as fibromyalgia or chronic fatigue syndrome in the classification of mental disorders.

Dr Reed has said that the easiest way to make this absolutely clear will be through the use of exclusion terms. However, he has said that he would be unable to request that exclusion terms are added to relevant Mental and behavioural disorders categories (e.g. Bodily distress disorder) until the conditions that are being excluded exist in the classification; that at such time, he would be happy to do so.

In August 2014, I submitted two FOI requests, one to the Scottish Health Directorate, one to the English Department of Health. The latter was not deemed specific enough in terms of named health agencies for a response to be generated, but I did receive information regarding the former.

Extract from FOI Response: September 24, 2014: FOI request fulfilled by (SCOTLAND) ACT 2002 (FOISA),

Information held covering the time period indicated relates to an email exchange on 11 and 12 March 2014 as part of a request for advice in answering Ministerial correspondence.

On 11 March the World Health Organisation WHO were asked “I would be very grateful for your help in confirming the status of an element within the WHO’s ICD 11 regarding ME/CFS. On 25th February in the UK parliament, the Under-Secretary of State for Health informed the UK parliament that the WHO had publicy stated that there was no proposal  to reclassify ME/CFS in ICD-11…I would be very grateful if you can confirm that this is the case and if possible, provide a web link to the original wording so I can include this within the correspondence I am preparing”.

The WHO responded on 12 March; “The question regarding MS/CFS [sic] and ICD-11 has been asked recently by several different parties. At this point in time, the ICD-11 is still under development, and to handle this classification issue we will need more time and input from the relevant working groups. It would be premature to make any statement on the subject below.

The general information on ICD Revision can be accessed here: http://www.who.int/classifications/icd/revision/. The current state of development of ICD-11 (draft) can be viewed here (and comments can be made, after self registration): http://www.who.int/classifications/icd11 ”.

A further email on 12 March to the WHO asked; “It would be fair to say then …that work will continue on the draft with an expected publication in 2015?”.

WHO responded on 12 March; “Work on the draft will continue until presentation at the World Health Assembly in 2017**. Before, reviews and field testing will provide input to a version that is available for commenting, as much as possible and proposals can be submitted online* with the mechanisms provided already.”

*Since the three terms are currently not accounted for within the Beta draft this impedes the submission of comments.

**Rescheduled in May, this year; the proposed target for presentation for WHA approval is currently May 2018.

This is all that has been disclosed by WHO/ICD Revision in respect of current proposals for the classification of the three ICD-10 G93.3 terms, despite the fact that ICD-11 has now been under development for 8 years, and prior to the timeline extension in January 2014, the new edition had been scheduled for WHA approval and dissemination in 2015.

There remain 6 important questions to be answered by WHO/ICD Revision:

• under which chapter(s) are PVFS, BME and CFS proposed to be located?
• under which parent classes?
• what hierarchies are proposed, in terms of coded for Title terms, Inclusions, Synonyms?
• which of the terms are to be assigned definitions?
• where will definitions be sourced from?
• when will the terms be restored to the draft to enable scrutiny and comment?

Important caveats: The public Beta platform is not a static document, it is a work in progress, subject to daily editing and revision, to field test evaluation and to approval by the RSG and WHO classification experts. Not all new proposals may survive the ICD-11 field tests. Chapter numbering, codes and “sorting codes” currently assigned to ICD categories are not stable and will change as chapters and parent/child hierarchies are reorganized. The public version of the Beta is incomplete; not all “Content Model” parameters display or are populated; the draft may contain errors and omissions.

Update: August 6, 2015

ICD Revision has now published a revised Project Plan and Communication Schedule:

ICD Project Plan 2015 to 2018


As previously posted


And so it goes on…

The revision of ICD-10 and development of ICD-11 kicked off in April 2007. The original projected WHA adoption date was 2011/12 [1].

Then a shift to 2015, then to 2017.

WHO has just kicked the can further down the road to May 2018.

In July 2014, the World Health Organization (WHO) Office of the Assistant Director General, Health Systems and Innovation, posted a call for expressions of interest from suitable contractors to conduct an interim assessment of the 11th Revision for International Classification of Diseases (ICD).

External assessment was prompted by concerns raised by WHO Member States, UN Statistical Commission and other stakeholder organizations about the status of the revision and the utility of the ICD-11 product.

The External review of ICD-11 Revision’s progress has now been completed.

Last week, WHO quietly released a report on the status of the ICD revision process, its management and resources, the feasibility of meeting its goals and timelines, and its fitness for purpose.

The reviewers’ assessment and recommendations can be read here: External report

Read WHO’s initial response to the report’s findings and the actions ICD Revision proposes to take here: WHO Response to External Report

WHO says:

WHO welcomes the constructive messages of the Report of the ICD-11 Revision Review. WHO is initiating the second phase of the revision process, acting immediately on the Review’s recommendations.

A revised workplan will be formulated before the end of June and submitted for approval to the RSG-SEG. During 2015 the WHO secretariat will be strengthened in terms of project management, communication of progress and plans, documentation and transparency of decision-making and classification expertise, as recommended by the reviewers.

As I predicted, a further shift in the development timeline from WHA adoption in May 2017 to May 2018 is proposed, along with other measures.

ICD-11 revision process: External assessment now due April 1

Post #317 Shortlink: http://wp.me/pKrrB-42A

This post is the first in a series of updates on the ICD-11 revision process.

Last July, in Call for Expressions of Interest to review the ICD revision process, I reported that the World Health Organization (WHO) Office of the Assistant Director General, Health Systems and Innovation had posted a call for expressions of interest from suitable contractors to conduct an interim assessment of the 11th Revision of the International Classification of Diseases (ICD).

Lead time was four months, with the completed final report targeted for submission to WHO by December 15, latest.

With no sign of a report in the offing, I asked WHO’s Bedirhan Üstün, last week, whether an interim assessment had been delivered in December and did WHO intend to publish a summary report.

Dr Üstün confirmed on January 10 that the external report will now be delivered by April 1 and that it “will certainly be made available.”

So the delivery of this interim assessment has slipped targets by some 15 weeks.

I have no information about the contractors who successfully pitched for the review and no date by which WHO aims to release a copy of the report’s findings (or summary of key findings).

The Call for Expressions of Interest to review the ICD revision process Terms of Reference document can still be downloaded from the WHO website, here:

or open, here, on Dx Revision Watch:

ICD-11 Beta drafting platform

Go here for the public version of the ICD-11 Beta drafting platform.

According to Slide #4 of this WHO presentation on Slideshare, the Joint Linearization for Mortality and Morbidity and Statistics (JLMMS) was expected to be frozen at certain points during the review process.

If you are registered with the public Beta platform for increased access and interaction with the draft, there are dropdowns from the Info tab for Downloads and Frozen Releases, eg:

Linearization Print Versions

Simplified Linearization Outputs

Linearization Index Tabulations

Frozen Releases

You may find the frozen release downloads here


When viewing the ICD-11 Beta drafting platform bear in mind that the platform may still be subject to freeze and more recent proposals will have been made across all chapters.

From the Contributions tab, you can pull up the Proposals pages for specific terms or view the Proposals List. New proposals are added on a daily basis and date back to July 2014.

Proposals can be filtered according to Proposal Status (Saved; Submitted; External Review, Accepted, Implemented, Rejected etc.) or filtered by Proposal Type.

Before scrutinizing or quoting from the public version of the Beta draft, I strongly advise that you first check the Proposals List for more recent revisions since the public Beta drafting platform may not display the most recent proposals.

You may find later proposals for revisions to the text of definitions and other Content Model descriptors; additions or deletions to Inclusions, Exclusions, Synonyms; deletions or additions of entities; revisions to terminology; proposals for complex hierarchical changes etc. Please also read these Caveats.

Caveats: The ICD-11 Beta drafting platform is not a static document: as a work in progress, it is subject to daily edits and revisions, to field test evaluation and to approval by ICD Revision Steering Group and WHO classification experts. Not all new proposals may survive internal/external review or field testing. Chapter numbering, codes and sorting codes currently assigned to ICD categories may change as chapters, entities, content and parent/child hierarchies are reorganized. The public version of the Beta draft is incomplete; not all “Content Model” parameters display or are populated; the draft may contain errors and omissions of categories and Index terms.
