Forward-ME Group | ‘Vital that the new WHO classification continues to provide a bulwark against medical mismanagement of M.E.’ | 21 April 2017

The Forward-ME Group has responded to the latest proposals to update the classification of M.E. and CFS in the World Health Organisation’s next version of the International Classification of Diseases (ICD-11). Implicit in their comments below is recognition of the huge amount of work put into this project by ME/CFS advocates Suzy Chapman and Mary Dimmock.


THE FORWARD-ME GROUP STATEMENT BEGINS HERE

Forward-ME is a group of UK charities and voluntary organisations convened by the Countess of Mar, in order to promote effective joint working by M.E. and CFS organisations.

The organisations are ME Association, ME Research UK, Action for M.E., Tymes Trust, reMEmber CFS, Blue Ribbon Awareness of ME (BRAME), ME Trust, the 25% ME Group, and Invest in ME.

We are in agreement that, as proposed here, it is particularly important for Myalgic encephalomyelitis (M.E.) and Postviral fatigue syndrome – presently classified in the Chapter on Diseases of the nervous system [at G93.3] – to be retained in that chapter of the forthcoming ICD-11.

Along with commending the proposal’s intention to highlight and reinforce the severe and devastating impact of M.E., we would like to draw attention to the body of scientific material referred to in the rationale for the proposal [Rationale point 1: Scientific evidence that exists for neurological dysfunction; Rationale point 2: Recent federal agency reviews and scientific evidence].

This reflects growing evidence of neurological, immunological and endocrinological dysfunction and related biomarkers. However, we agree that current scientific evidence of neurological impairment and WHO/ICD Revision’s position on precedence [i.e. “legacy should trump with regard to the question of moving certain conditions to new chapters”] supports retention of chronic fatigue syndrome and myalgic encephalomyelitis in Diseases of the nervous system.

We support the proposal to move Postviral fatigue syndrome to a synonym under the Concept Title ‘Myalgic encephalomyelitis’. This recognises that not all instances of M.E. may result from a viral infection. We also agree with the proposed removal of the word ‘benign’ from the M.E. title, in keeping with the considerable medical complexity of this condition and its severe and lasting impact on patients.

The position in respect of ‘Chronic fatigue syndrome’ (CFS) is more complex:

  • CFS is listed in the WHO ICD-10 index only.
  • It is indexed to G93.3. Yet in practice the label ‘CFS’ is applied variably – both in research (with a multiplicity of definitions in use) and clinically.

Given the placement of ‘Fatigue syndrome’ in the WHO ICD-10 Mental and behavioural chapter [as a synonym under ‘Neurasthenia’ at F48.0], it was all but inevitable that the introduction of the term ‘Chronic fatigue syndrome’ to apply to a physical illness would cause confusion.

The confusion has a considerable impact on patients. For example, we are aware that some patients are being referred to services for ‘medically unexplained symptoms’, under the mistaken assumption that M.E. is a ‘functional somatic syndrome’. Indeed, the Joint Commissioning Panel for Mental Health (England) has recently published guidance stating that ‘Chronic Fatigue Syndrome/Myalgic Encephalomyelitis’ is a ‘functional somatic syndrome’ [Guidance for commissioners of services for people with medically unexplained symptoms 2017].

As the evidence gathered by this proposal so clearly demonstrates, this illness is a “serious, chronic, complex, and multisystem disease” that causes significant impairment – including neurological, cognitive, immunological, autonomic and energy metabolism disorder. We consider that it is vital that the WHO ICD continues to provide a bulwark against medical mismanagement of M.E. patients.

In this regard securing appropriate exclusions is vital, and we endorse the proposal’s recommendations, as set out at Note 4. In particular, we note that the ICD revision intends that the F48.0 Neurasthenia category [where ‘Fatigue syndrome’ presently appears], together with almost all of the present F45 somatoform disorder categories, be subsumed in a single new category – currently suggested name ‘Bodily distress disorder’. We agree that there needs to be reciprocal exclusions for M.E. and for CFS for the ‘Bodily distress disorder’ category.

We also agree that reciprocal exclusions for M.E. and for CFS for the category ‘Fatigue’ [previously ‘Malaise and fatigue’] are essential.

Q and A for Proposal for the ICD-10 G93.3 legacy terms for ICD-11

Post #332 Shortlink: http://wp.me/pKrrB-4g2

To ensure that the ICD-10 G93.3 legacy categories are present and appropriately classified in ICD-11, U.S. advocate Mary Dimmock and I submitted a formal and fully referenced proposal on March 27, 2017.

Here is a Q & A addressing some of the questions raised in relation to our proposal:

Q & A version 1, April 2017

Proposal for the ICD-10 G93.3 legacy terms for ICD-11, submitted by Suzy Chapman and Mary Dimmock on March 27, 2017

PDF: http://bit.ly/Proposal111QA

 

Q & A version 1 covers:

Q1: Your proposal for ICD-11 does not recommend retiring CFS. Why is that?
Q2: Are PVFS, (Benign) ME and CFS classified the same across all versions of ICD-10?
Q3: How is ICD Revision proposing to classify the G93.3 legacy terms?
Q4: Is there any proposal to classify the terms under Mental or behavioural disorders?
Q5: Will ICD-11 look and function differently to ICD-10?
Q6: What is the implementation date for ICD-11?
Q7: Is ICD-11’s “Bodily distress disorder” the same as Fink’s “Bodily distress syndrome”?
Q8: Where can I view the Beta draft and comment on your proposal?

 

Our proposal recommends:

  • that the terms should be retained in the neurological chapter (Chapter 08: Diseases of the nervous system);
  • that the terms should be retained under the parent class: Other disorders of the nervous system;
  • that ME and CFS should each be assigned separate codes;
  • that PVFS is not an appropriate title term for ME to sit under (not all cases of ME are preceded by a virus).

We’ve also recommended:

  • reciprocal exclusions for “Bodily distress disorder” and for general Fatigue;
  • that the designation “Benign” should be dropped for ICD-11.

Our proposed restructure for ICD-11 looks like this:

April 4, 2017 Frozen Release of ICD-11 Beta draft for centres undertaking field testing

Post #331 Shortlink:  http://wp.me/pKrrB-4fc

As scheduled, ICD Revision posted a Frozen Release of the ICD-11 Beta draft today, April 4, 2017.

This is a stable version of the draft for use by the centres that are signed up for field testing the Beta draft for utility.

This PDF document sets out information of the field trial process:

ICD-11 Field Trials, Information and Terms of Engagement, 17 March 2017

The Frozen Release can be accessed here (Registration required for access):

Here are screenshots from the April 4, 2017 Frozen Release for the ICD-10 G93.3 legacy terms, “postviral fatigue syndrome,” “benign myalgic encephalomyelitis,” and “chronic fatigue syndrome.”

There is no change to these terms in the Frozen Release compared with how they had stood on March 26, when the three terms were finally restored to the Beta draft.

Frozen Release: April 4, 2017: Postviral fatigue syndrome

Fatigue, below, displaying exclusions for BME and CFS. Two of the longstanding proposals that I had submitted on December 30, 2014, were approved and marked as “Implemented” on March 26, when the G93.3 legacy terms were finally returned to the draft with this caveat:

“While the optimal place in the classification is still being identified, the entity has been put back to its original place in ICD.” Team WHO 2017-Mar-26 – 12:46 UTC

NB: My proposal of December 30, 2014 for an exclusion for the concept title “Postviral fatigue syndrome” was not approved and implemented on March 26, when PVFS’s two inclusion terms were approved. I have queried the rationale for this apparent anomaly with “Team WHO” but have yet to receive any response.

A proposal for the ICD-10 G93.3 legacy terms for ICD-11: Part Two

Post #330 Shortlink: http://wp.me/pKrrB-4eH or http://bit.ly/ICD11proposal
For background to Part Two see: A proposal for the ICD-10 G93.3 legacy terms for ICD-11: Part One

Update: A PDF Q & A for our proposals can be downloaded here

 

In the World Health Organization’s ICD-10, the terms, “postviral fatigue syndrome,” “benign myalgic encephalomyelitis,” and “chronic fatigue syndrome,” are all classified to G93.3, in the neurological chapter, as below:

Image source: ICD-10 Version: 2016

The next edition of ICD (ICD-11) is scheduled for release at some point in 2018, following presentation at the World Health Assembly (WHA), in May 2018.

The WHO work group with responsibility for the G93.3 legacy categories removed the terms from the publicly accessible version of the ICD-11 Beta draft, in early 2013, while they deliberated over how these categories should be represented in ICD-11.

On March 26, after a four year absence from the draft, “Team WHO” finally restored the G93.3 terms to the Beta platform.

Two long standing proposals for inserting exclusions under Fatigue for Benign myalgic encephalomyelitis and Chronic fatigue syndrome were also approved on March 26.

The three G93.3 legacy terms were returned to their 2009 Beta location with this caveat:

“While the optimal place in the classification is still being identified, the entity has been put back to its original place in ICD.”

This suggests that we should view this as a “placeholder” and that the Topic Advisory Group for Neurology may release revised proposals later this year.

WHO has confirmed there is no intention to classify the terms under the Mental or behavioural disorders chapter or under the Symptoms, signs chapter.

 

How does the draft currently stand?

All three terms are currently back under the Neurology chapter, under parent: Other disorders of the nervous system, with PVFS as the lead (or concept title) term. BME and CFS are specified as inclusion terms (so they are coded to the same code as PVFS). All other content on the listing is much as it had stood in the Beta, in 2009.

(This is almost the same hierarchy as in ICD-10, except CFS is now included in the ICD-11 equivalent of the Tabular List, whereas in ICD-10, CFS is included only in the Index. Canada, Germany and the U.S. already have all three terms in their Tabular Lists.)

This is how the terms currently appear in the Beta draft:

https://icd.who.int/dev11/f/en#/http://id.who.int/icd/entity/569175314

In view of the caveat, it remains unclear what Topic Advisory Group for Neurology might still be considering for these terms, when they will reach consensus, or whether alternative proposals might be released at some point.

There was a proposals deadline on Thursday, March 30. Proposals received after this date may have to wait until after the ICD-11 is tested and released to be considered for inclusion in the first annual update of ICD-11, in 2019.

 

A proposal for ICD-11

To ensure that these terms are present and appropriately classified in ICD-11, U.S. advocate Mary Dimmock and I have collaborated on the preparation of a proposal for the restructure of the ICD-10 G93.3 category terms: Postviral fatigue syndrome; Benign myalgic encephalomyelitis; and Chronic fatigue syndrome.

We submitted a formal and fully referenced proposal on March 27.

Our proposal recommends:

  • that the terms should be retained in the neurological chapter (Chapter 08: Diseases of the nervous system);
  • that the terms should be retained under the parent class: Other disorders of the nervous system;
  • that ME and CFS should each be assigned separate codes;
  • that PVFS is not an appropriate title term for ME to sit under (not all cases of ME are preceded by a virus).

We’ve also recommended:

  • reciprocal exclusions for “Bodily distress disorder” and for general Fatigue;
  • that the designation “Benign” should be dropped for ICD-11.

Our proposed restructure for ICD-11 looks like this:

A proposal for the ICD-10 G93.3 legacy terms for ICD-11: Part One

Post #329 Shortlink: http://wp.me/pKrrB-4dV

Our Proposal and Rationale is set out in Part Two:

A proposal for the ICD-10 G93.3 legacy terms for ICD-11: Part Two

A version of ICD-11 in 2018

It’s been a long time coming and it ain’t finished yet…

The World Health Organization (WHO) has been revising ICD-10 since 2007.

After several shifts in the timeline, WHO plans to present a version of the next edition (ICD-11 MMS) at the World Health Assembly (WHA), in May 2018.

WHO won’t be seeking endorsement of the ICD-11 product in May 2018 because it won’t be ready to implement. Endorsement will be sought at some point in the future. In the meantime, a version of ICD-11 is scheduled for release later in 2018, after the May assembly. The release date has yet to be announced.

https://hscic.kahootz.com/connect.ti/t_c_home/view?objectId=297939

“…The World Health Organization (WHO) is currently developing the 11th revision of ICD. Once endorsed by the World Health Assembly (WHA), WHO Nomenclature regulations stipulate that Member States must use the most current revision for mortality and morbidity purposes. For this reason and to allow member countries to adopt the new revision when they are ready, WHO will brief the WHA on ICD-11 in May 2018 but will not seek endorsement at this time.”

Member states will transition from ICD-10 to the new edition at their own pace. It’s going to be several years before countries have evaluated the ICD-11 product for utility and prepared their health systems to make the transition.

At some point, data using codes from the new edition will be accepted alongside data compiled using ICD-10. WHO will continue to support ICD-10 until the majority of member states have adopted and implemented the new edition.

It will take even longer for countries like the U.S. and Canada, who use a country specific adaptation of ICD, to implement as they will need to modify the new edition to suit their countries’ health systems. The earliest Canada can implement is currently projected as 2023 [1]. The U.S.’s CDC estimate it will take at least 6 years after the codes have been ratified to prepare, field test and implement an ICD-11-CM/PCS.

 

Proposal deadlines

Some important deadlines for proposals for the ICD-11 Beta draft:

The deadline in order for proposals to be considered for a frozen version in March/April 2017 was 30 December 2016.

In order for proposals to be considered for inclusion in the version of ICD-11 that is scheduled for release in 2018, they needed to be submitted by March 30, 2017. So those two deadlines have been reached.

Comments by member states and improvements arising as a part of the Quality Assurance mechanism will be included with deadlines later in 2017.

According to Slide #12 in this November 2016 WHO presentation, the deadline for member state comments is May 31, 2017; the deadline for Field Testing and Quality Assurance is June 30, 2017 [2]. But these dates are unconfirmed and may have been revised since November, last year.

Proposals received after the end of May will be considered in the context of ICD-11 maintenance after 2018, when the new version will be subject to an annual update and maintenance schedule [3]. The first annual update is anticipated in 2019.

The Joint Task Force is considering naming each year’s iteration in the format: ICD 2018; ICD 2019; ICD 2020 and so on. There may never be a need for an ICD-12, since an electronic system is better able to evolve “gracefully” – as Dr Christopher Chute (Joint Task Force; Chair, Revision Steering Group) puts it – in response to advances in scientific knowledge and classificatory changes.

 

Deadlines for submitting comments

I have asked Dr Jakob and the Joint Task Force to clarify by what date comments on proposals that met the March 30 deadline will need to be submitted by in order to be considered in the context of the earliest release of ICD-11, in 2018.

No clarification has been forthcoming; so if you are a stakeholder considering submitting a comment on existing proposals in the Beta draft or on outstanding proposals queued in the “Proposals Mechanism” which are still going through the review process, then I would advise that you put this in hand over the next couple of weeks. If any deadline is announced, I will update at the top of this report.

 

Frozen release

On April 4, ICD Revision is scheduled to release a frozen version of ICD-11 MMS for field testing*. If there are any changes in this April 2017 Frozen Release that are relevant to stakeholders in the G93.3 terms, I will post an update at the top of this report.

*ICD-11 Field Trials, Information and Terms of Engagement, March 17, 2017 https://hscic.kahootz.com/gf2.ti/af/762498/122441/PDF/-/ICD11_FT_Information_and_ToE.pdf

 

Current status of the ICD-10 G93.3 legacy categories

The ICD-10 G93.3 legacy categories: Postviral fatigue syndrome; Benign myalgic encephalomyelitis and Chronic fatigue syndrome were taken out of the public version of the Beta draft in early 2013, with no explanation for their absence.

ICD Revision has maintained a cephalopodic grip on its intentions for these terms.

Advocates and patient organization stakeholders have been attempting to obtain transparency from ICD Revision around the Topic Advisory Group for Neurology’s proposals for these terms for over four years. During this period, stakeholders have been disenfranchised from participation in the revision process.

 

Questions raised in the English Parliament

15 international stakeholder organizations wrote to the ICD-11 MMS Joint Task Force, in February, in support of my call that the Joint Task Force place the matter of the continued absence of proposals for these terms on the Agenda of their February 20–22 meeting, in Cologne.

There were asked to expedite the release of proposals for public scrutiny and comment before the March 30 deadline.

This initiative was met with a disturbing level of obfuscation on the part of WHO and the Joint Task Force, especially given that ICD Revision has been promoted as an open, transparent process, inclusive of stakeholder participation.

The Countess of Mar, a long standing advocate for patients with ME and CFS, tabled two Written Questions in the House of Lords. The first is here (February 27), which received a response that raised more questions than it answered and a follow up question, here (March 16), which received an equally opaque reply.

But on March 26, the three terms were finally restored to the Beta draft – but with this caveat:

“While the optimal place in the classification is still being identified, the entity has been put back to its original place in ICD.”

Team WHO 2017-Mar-26 – 12:46 UTC

This suggests that we should view the restoration of the terms as a “placeholder” and that the work group may release revised proposals later this year.

 

What do we know?

WHO has confirmed that there is no intention to classify the ICD-10 G93.3 legacy terms under the Mental or behavioural disorders chapter or under the Symptoms, signs chapter.

“Team WHO” has also approved some long standing proposals for exclusions for two of these terms under Fatigue (but not yet approved an exclusion for Postviral fatigue syndrome and I have asked “Team WHO” for the rationale for this apparent anomaly, since one would anticipate that if the inclusion terms are excluded under Fatigue, the ICD concept title entity would also be excluded). Possibly, TAG Neurology has other plans for the classification of PVFS in ICD-11.

So, nearly 10 years into the revision process, it’s still unclear what the work group might be considering for these terms, when they will reach consensus, or whether alternative proposals might be released on April 4, when a frozen version of ICD-11 is scheduled for release for field testing.

 

How do the terms currently stand in ICD-10?

This is how the G93.3 legacy terms were represented in ICD-10:

For ICD-10, Postviral fatigue syndrome (PVFS) is the lead (or concept title) term. Benign myalgic encephalomyelitis is the inclusion term under PVFS and takes the G93.3 code. Chronic fatigue syndrome is listed only in the Index, and coded to G93.3.

 

How do the terms stand in ICD-11 Beta draft, now they have been restored?

Since March 26, 2017, for ICD-11 Beta draft, all three terms are currently back under the Neurology chapter, under parent: Other disorders of the nervous system. PVFS is the lead (or concept title) term. BME and CFS are both specified as inclusion terms to PVFS, in the ICD-11 equivalent of the Tabular List. The terms listed under synonyms and all other “Content Model” descriptive content appear much as the Beta had stood in 2009.

But given the caveat, it is still unknown what the work group might be considering for these terms or whether or when they might release further proposals.

Note that the recommendations of the various external work groups are advisory only. WHO classification experts and the Joint Task Joint can, and sometimes do, overrule work group decisions.

If the Topic Advisory Group for Neurology, that has responsibility for these terms, were to reach consensus and release an alternative set of proposals before 2018, these will not necessarily obtain the approval of WHO/Joint Task Joint.

 

Suzy Chapman and Mary Dimmock have submitted a proposal

To address this situation, U.S. advocate, Mary Dimmock, and I have collaborated on the preparation of a formal and fully referenced proposal which we submitted on March 27. Our proposal (in the PDF below) recommends that these terms should be retained in the neurological chapter, using separate codes for ME and CFS, and also makes other recommendations.

Changes to SNOMED CT and Read Codes (CTV3) for CFS, ME and PVFS

Post #327 Shortlink: http://wp.me/pKrrB-4aD

Recent changes to SNOMED CT for CFS, ME and PVFS

  • Correspondence between Forward-ME and UK Health and Social Care Information Centre
  • SNOMED CT retires Mental disorder parent for Chronic fatigue syndrome and ME
  • Projected changes to April 2016 release of Read Codes Clinical Terms Version 3 (CTV3)
  • Read Codes system to be phased out as part of wider SNOMED CT implementation

In addition to ICD-10, a number of terminology and electronic health and medical record systems are used in the UK in primary, secondary, and health and social care clinical settings, which include:

OPCS-4 (classification of Surgical Operations and Procedures)

SNOMED CT (Systematized Nomenclature of Medicine – Clinical Terms, a comprehensive, multilingual clinical terminology system)

Read Codes (a coded thesaurus of clinical terms for recording patient findings and procedures in health and social care IT systems across primary and secondary care, e.g. GP surgeries and reporting of pathology results).

The National Information Board (NIB) has specified that all primary care systems adopt SNOMED CT by the end of December 2016 and that SNOMED CT is to be used as the single terminology in all health care settings in England, with a projected adoption date for the entire health system of April 2020 [3].

You can access a public SNOMED CT browser here: IHTSDO browser

This is an online browser and does not require any software to be downloaded. You will need to accept the license and then select for the UK “Local Extension” of SNOMED CT. Click on the “Search” tab to enter clinical terms.

The SNOMED CT International Edition and “Local Extensions” for a number of other countries, including the US, are also available via the browser. All editions release new updates twice a year, on a staggered schedule. The Release schedule for the UK Extension is April and October.

Read Codes system to be retired

The Read Codes system of clinical terms has been used in the NHS since 1985. As part of the adoption of SNOMED CT in primary care, Clinical Terms Version 3 (CTV3) is being deprecated.

More information on the phasing out of Read Codes, here:

There was no new release for CTV3 issued in October, but the April 2016 release is scheduled for Friday, 18th March 2016. The last release of CTV3 will be published in April 2018.

How have CFS and related terms been listed within SNOMED CT and CTV3?

SNOMED CT

Prior to July 2015, all editions of SNOMED CT had the following listings for CFS, ME and PVFS:

Chronic fatigue syndrome (with ME – Myalgic encephalomyelitis and several other related and historical terms listed under Synonyms) was assigned two parent disorder classes: Mental disorder, and Multisystem disorder.

Postviral fatigue syndrome was listed under Children to Chronic fatigue syndrome.

Read Codes (CTV3)

The twice yearly Read Codes releases (April and October) are available only to license holders but the codes can be viewed through this public resource (caveat: it is unclear how often this NCBO BioPortal ontology resource is updated with new releases for individual ontology systems):

See: BioPortal Xa01F

For CTV3, Xa01F Chronic fatigue syndrome (with ME – Myalgic encephalomyelitis and PVFS – Postviral fatigue syndrome under Synonyms) is listed, hierarchically, under two parent disorder classes: as a Sub Class of both Neurasthenia, under parent: Mental health disorder, and as a Sub Class of Neurological disorder.

See: http://purl.bioontology.org/ontology/RCD/Xa01F

Mental health disorder > Neurotic disorder > Somatoform disorder > Neurasthenia > Chronic fatigue syndrome

and

Neurological disorder > Chronic fatigue syndrome

Correspondence between Countess of Mar and UK Health and Social Care Information Centre

Forward-ME is an informal group for ME charities and voluntary organizations, chaired by the Countess of Mar, who also serves as Co-chair to the All-Party Parliamentary Group on Myalgic Encephalomyelitis (ME).

Between November 2014 and June 2015, Lady Mar was in correspondence with Mr Leon Liburd, Senior Support Analyst Systems and Service Delivery, and Ms Elaine Wooler, Advanced Clinical Terminology Specialist, UK Health and Social Care Information Centre.

Their correspondence (in reverse date order) was published on the Forward-ME website in June and can be read here Correspondence re SNOMED added June 2015

Changes to SNOMED CT

As a result of these exchanges, Lady Mar was advised that the relationship between the entry for 52702003 Chronic fatigue syndrome and the Mental disorder parent had been retired. In future editions, Chronic fatigue syndrome would be listed under the single parent, 281867008 Multisystem disorder.

See here

Additionally, 51771007 Postviral fatigue syndrome was being removed as a subtype of 52702003 Chronic fatigue syndrome (disorder) – though no rationale for this specific decision appears to be provided within the correspondence.

See here

[So 51771007 Postviral fatigue syndrome would be no longer be listed as a sub class under Children to 52702003 Chronic fatigue syndrome but directly under two parents: 281867008 Multisystem disorder and 123948009 Post-viral disorder.]

These changes were effected in the July 2015 release for the International Edition (Release 20150731).

They were subsequently incorporated into the September 2015 US Extension (Release 20150901), the October 2015 UK Extension (Release 20151001) and the November 2015 Swedish Extension (Release 20151130). It is expected that other country Extensions will also reflect these changes in their forthcoming releases.

Within the correspondence, on 11 November 2014, Mr Leon Liburd had also advised Lady Mar:

“It is also noted that the corresponding representation in the UK’s Clinical Terms Version 3 terminology product Xa01F | Chronic fatigue syndrome is classified as both a Neurological disorder and a Mental health disorder. As such, any conclusions emerging from the SNOMED CT discussions would also be reflected in the CTV3 UK product.”

Clarification re CFS and CTV3

In November, I contacted the UK Health and Social Care Information Centre for clarification of how CFS and its various Synonyms are currently listed within CTV3.

On 20 November, I was advised by Karim Nashar, Terminology Specialist, UK Terminology Centre, Health and Social Care Information Centre, that:

“[Xa01F | Chronic fatigue syndrome was being moved] under a single supertype 281867008 | Multisystem disorder (disorder) as to reflect the SNOMED correction in CTV3″

and that this change should be reflected in the April 2016 CTV3 release.

As noted above, Clinical Terms Version 3 (CTV3) is being deprecated and the last release of CTV3 will be published in April 2018.

The ICD-11 Beta draft and proposed classification of the G93.3 legacy terms

In June, WHO’s Dr Robert Jakob had told me that if TAG Neurology’s proposals and rationales for the G93.3 legacy terms were not ready for public release in September, he projected their release by December, latest (see towards end of Post #324).

No proposals were released in September and none in December. 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.

On 28 December, I called again, via the ICD-11 Beta Comments mechanism, for these terms to be restored to the public version of the Beta drafting platform.
