Update on the removal of “neurasthenie” from SNOMED CT Netherlands Edition

Post #348 Shortlink: https://wp.me/pKrrB-4N6

As reported in Post # 345, the SNOMED CT Concept SCTID: 192439005 Neurasthenia (disorder) and its associated SCTID Concept terms were retired (Inactivated) from SNOMED CT’s International Edition and from national editions some years ago.

However, the Netherlands Edition retained the term neurasthenie under the SCTID: 52702003 chronischevermoeidheidssyndroom (CVS) Synonyms list. The neurasthenie term was exclusive to the Netherlands Edition, was assigned to the SCTID: 52702003 CVS code, and designated as an “Acceptable” Synonym term for CVS in the Netherlands Dutch language reference set.

Request for removal of the neurasthenie term:

In October 2018, a Netherlands advocate approached Pim Volkert (Terminology Co-ordinator, Nictiz, and lead for the Netherlands SNOMED CT National Release Centre) with a request and rationale for consideration of removal of the neurasthenie term, for consistency with SNOMED CT International Edition and with the WHO’s ICD-10, which specifically excludes G93.3 from F48.0 Neurasthenia.

This request and accompanying rationale was considered and promptly accepted for implementation in the March 31, 2019 release of the Netherlands Edition.

This approved content change has now been incorporated into the March 2019 release:

A note about retired SCTID Concept terms and retired Synonyms in SNOMED CT International Edition and national editions:

The technical term for the retirement of a SNOMED CT SCTID Concept or Synonym term is “Inactivation”. In order to display Inactive concepts, go to:


Accept the License Agreement, if displayed.

Select the specific edition required (eg the International Edition or one of the National Editions).

Look under Options on the left of the Search box.


“Status: Active and inactive concepts” from the Options dropdown.

Enter a search term into the Search box.

In the Matches list, Inactive concepts will display on a light pink ground.

Click on a term to display the historical Concept Details panel associated with that specific term (which will also display on a pink ground in the box under Parents in the Concept Details panel).

So although retired or “Inactive” terms can still be searched for within the SNOMED CT terminology browser, they are identified as Inactive by their pink ground.


References for intention not to retain Neurasthenia for ICD-11

Post #319 Shortlink: http://wp.me/pKrrB-439

When ICD-10 was completed in 1992, Chapter V Mental and behavioural disorders retained the disorder category term, Neurasthenia, coded at F48.0.

This is how Neurasthenia is listed within ICD-10:

F48.0 Neurasthenia (with Fatigue syndrome as inclusion term).


Neurasthenia and ICD-10-CM

The forthcoming U.S. specific ICD-10-CM inherits Neurasthenia in Chapter 5 Mental, Behavioral and Neurodevelopmental disorders (F01–F99). But here, it is coded under F48.8, owing to the different coding arrangement for the F48–F48.9 entities within ICD-10-CM.

This is how Neurasthenia is listed in the ICD-10-CM Tabular List release for FY 2015*

Neurasthenia ICD-10-CM

*Although the FY 2015 ICD-10-CM is now available for public download and viewing, the codes in ICD-10-CM are not currently valid for any purpose or use until implementation date is reached.


Neurasthenia and DSM

There was no discrete category for Neurasthenia within DSM-IV or DSM-IV-TR; nor within DSM-5, which published in May 2013.


Neurasthenia and ICD-11 and ICD-11-PHC

I reported in 2012 that for ICD-11 and ICD-11-PHC, the intention is not to retain Neurasthenia.

Here are the references:

Creed F, Gureje O. Emerging themes in the revision of the classification of somatoform disorders. Int Rev Psychiatry. 2012 Dec;24(6):556-67. http://www.ncbi.nlm.nih.gov/pubmed/23244611 [Full text behind paywall]

On Page 563 of this review paper, the authors state that a major highlight of the proposals of the ICD-11 Expert Working Group on Somatic Distress and Dissociative Disorders (the S3DWG sub working group) for the revision of the ICD-10 Somatoform disorders is that of subsuming all of the ICD-10 categories of F45.0–F45.9 and F48.0 under a single category with the proposed name of “Bodily distress disorder” (BDD).

ICD-10 PHC is a simplified version of the WHO’s ICD-10 chapter for mental and behavioural disorders for use in general practice and primary health care settings. This system has rough but not exact equivalence to selected of the mental disorders in the core ICD-10 classification.

The ICD-10 PHC includes and describes 26 disorders commonly encountered within primary care and and low resource settings, as opposed to circa 450 classified within Chapter V of ICD-10.

For ICD-11 PHC it is also the intention not to retain the category F48 Neurasthenia.

Here are the references for the primary care version:

International Psychiatry, Issue 1 Feb 2011, Royal College of Psychiatrists

Page1: Box 1 The 26 conditions included in ICD10-PHC

F45 Unexplained somatic complaints*
F48 Neurasthenia*

*Not to be included in ICD11-PHC

Publication date: August, 2012: http://www.jblearning.com/catalog/9781449627874/

See Page 51: Table 2.5 The 28 Disorders Proposed for ICD11-PHC

Note: If you compare the list of proposed disorders for the ICD-11 primary care version, as listed in the February 2011 International Psychiatry article (on Page 2, Box 2 The 28 disorders to be field tested for ICD11-PHC), with Table 2.5, above, you will note that some proposed disorder names, disorder groupings and disorder group headings have been revised since the article in International Psychiatry. Prof Goldberg has clarified that the iteration published in the sample book chapter was the more recent of the two, cf:

February 2011 iteration:

Body distress disorders

16 Bodily distress syndrome (new – was unexplained somatic complaints)
17 Health preoccupation (new)
18 Conversion disorder (was dissociative disorder)


Sample chapter (2012) iteration:

Body distress disorders

15 Bodily stress syndrome
16 Acute stress reaction
17 Dissociative disorder
18 Self-harm

This list of disorder proposals and groupings may have undergone further revision since publication of 21st Century Global Mental Health. But no progress reports have emerged on behalf of the Primary Care Consultation Group (PCCG) setting out more recent proposals for their “Bodily stress syndrome” construct since the Lam et al (July 2012) paper [1].

The disorder term and construct that is entered into the ICD-11 Beta draft and defined with three severities, is the S3DWG group’s conceptually different, but similarly named construct, Bodily distress disorder (BDD).

The ICD-11 S3DWG group is advising ICD Revision in parallel with the PCCG on a potential replacement for the ICD-10 Somatoform disorders.

It is the case, however, that some professional and consumer stakeholders are unaware that are two groups advising on the revision of the Somatoform disorders, that there have been two sets of proposals presented, or how they differ in conceptualization.

Four revised definition texts were submitted to the Proposals List on behalf of Mental Health TAG for “Bodily distress disorder (BDD)” on January 9–11, which will be the subject of a future post.


Further evidence of intention for Neurasthenia and ICD-11

In mid 2012, Neurasthenia was removed from the ICD-11 Beta draft and subsumed (along with the F45.0–F45.9 category terms) by the S3DWG’s new single diagnostic category, “Bodily distress disorder.”

However, a couple of redundant listings for Neurasthenia as an exclusion term remained in the Beta draft as legacy text from ICD-10, under Exclusions to Fatigue (Symptoms and signs chapter) and Generalized anxiety disorder (Mental and behavioural disorders chapter).

The deletion of Neurasthenia as an exclusion term to Fatigue has now been attended to.

The following proposal has been submitted via the Proposals facility on behalf of Mental Health TAG to address the legacy listing that remains under Generalized anxiety disorder and this provides additional and contemporary evidence of intention not to retain Neurasthenia as a disorder term for ICD-11:

Proposals List

Content Enhancement Proposal

Exclusion to Generalized anxiety disorder



Neurasthenia is not recommended for retention as a disorder category in ICD-11. Therefore, this exclusion term is not longer necessary.

If the concept is not retained in ICD-11, then the concept would be marked as obsolete rather than deleted. Thank you!

ICD-11 Beta drafting platform: Update (2)

ICD-11 Beta drafting platform: Update (2): Neurasthenia, Postviral fatigue syndrome (PVFS), Benign myalgic encephalomyelitis (ME), Chronic fatigue syndrome (CFS), Fibromyalgia (FM), Irritable bowel syndrome (IBS)

Post #193 Shortlink: http://wp.me/pKrrB-2mC

The information in this report relates to proposals for the World Health Organization’s forthcoming ICD-11, currently scheduled for pilot dissemination in 2015+; it does not apply to the existing ICD-10 or to the forthcoming US specific “clinical modification” of ICD-10, known as ICD-10-CM.

Caveat: The ICD-11 Beta drafting process is a work in progress over the next two to three years. The Beta draft is updated on a daily basis. Parent terms, category terms and sorting codes assigned to categories are subject to change as chapter reorganization progresses. Images and text in this posting may not reflect the most recently assigned categories and codes. This post reflects the Beta draft as it stood at July 25, 2012. Please also read the ICD-11 Beta Draft Caveats.

Post #190 Changes to ICD-11 Beta drafting platform: Bodily Distress Disorders (1) reported on proposals for including three Bodily distress disorder categories in the Somatoform Disorders section of the ICD-11 Beta drafting platform which appear potentially to replace or subsume a number of existing ICD-10 Somatoform Disorder categories.

That post has been revised to reflect clarifications from Professor, Sir David Goldberg, M.D., around the Primary care version of ICD-11 and to include additional material.

The report in this post updates on current proposals for the ICD-11 Beta drafting platform for revision of the following ICD-10 categories: Neurasthenia, Postviral fatigue syndrome (PVFS), Benign myalgic encephalomyelitis (ME), Chronic fatigue syndrome (CFS), Fibromyalgia (FM) and Irritable bowel syndrome (IBS) for the full version of ICD-11.

ICD Revision Steering Group and the various Topic Advisory Groups are developing the ICD-11 Beta draft on a non public access collaborative authoring platform where change histories can be tracked, which looks similar to this:

The publicly viewable version of the Beta drafting platform looks like this:

and displays less information. It can be accessed here:

Beta draft Foundation Component (FC) view:


Beta draft Linearization Morbity (LM) view:


Increased access to content and interaction with the drafting process can be obtained by registering.

Neurasthenia is not classified in DSM-IV and is not proposed to be classified in DSM-5.

In ICD-10, Neurasthenia is classified in Chapter V Mental and behavioural disorders under parents:

F40-F48 Neurotic, stress-related and somatoform disorders

    F48 Other neurotic disorders
        ›  F48.0 Neurasthenia

For ICD-11 Beta, up until July 3, Neurasthenia was also classified under:

Neurotic, stress-related and somatoform disorders

    9S1 Other neurotic disorders
        ›  9S1.1 Neurasthenia

Inclusions: Fatigue syndrome

Exclusions: psychasthenia
postviral fatigue syndrome
malaise and fatigue
asthenia NOS

    9S1.2 Other specified neurotic disorders

Inclusions: Dhat syndrome
Occupational neurosis, including writer’s cramp
Psychasthenic neurosis
Psychogenic syncope

     9S1.3 Neurotic disorder, unspecified

Neurosis NOS


On July 4, all child categories classified under parent class, 9S1 Other neurotic disorders, including Neurasthenia and its Inclusion, Fatigue syndrome, were removed from both the FC and LM view and from the PDF for the Chapter 5 Print version and there is currently no listing for any of these categories and child categories under any parent.

As no “Change history” records display in the public version of the Beta draft, it cannot be determined from what information is available whether these categories are temporarily omitted while this section of Chapter 5 is being reorganized, or whether all or selected of these ICD-10 categories are proposed to be retired for ICD-11 or are destined to be subsumed under the proposed Bodily distress disorders categories that ICD Revision has yet to define.

According to the Goldberg February 2011 report, terms included in the ICD11-PHC version of ICD-11 must have an equivalent disorder in the main classification. In February 2011, it was proposed not to include Neurasthenia in the ICD11-PHC version but to subsume under 13 Distress disorder. (It isn’t clear under which disorder group or subcategory Neurasthenia is proposed to be subsumed for the most recently published iteration for ICD11-PHC.)

Neurasthenia remains listed as an Exclusion to Chapter 5 Generalized anxiety disorder and Chapter 18 Malaise and fatigue but these Exclusions may be awaiting attention, if the intention is to retire a number of ICD-10 terms.

I will update when it becomes apparent what the intention is for these currently missing categories.

ICD-11 Chapter 06: Diseases of the nervous system

Postviral fatigue syndrome, Benign myalgic encephalomyelitis, Chronic fatigue syndrome:

In ICD-10, Postviral fatigue syndrome is classified as a Title term within Volume 1: The Tabular List in Chapter VI: Diseases of the nervous system under G00-G99 Other disorders of the nervous system > G93 Other disorders of brain, and coded at G93.3. See: http://apps.who.int/classifications/icd10/browse/2010/en#/G93.3

Benign myalgic encephalomyelitis is also coded in the Tabular List to G93.3 Postviral fatigue syndrome.

Chronic fatigue syndrome is not classified within the Tabular List but is indexed to G93.3 in Volume 3: The Alphabetical Index.

An unauthorised copy of Volume 3: The Alphabetical Index Version for 2006 can be accessed here: (See Page 528)

In indexing Chronic fatigue syndrome to G93.3, ICD-10 does not specify whether it views the term as a synonym, subclass or “best coding guess” to Title term, Postviral fatigue syndrome or to Benign myalgic encephalomyelitis.

Nor does ICD-10 specify the relationship between Postviral fatigue syndrome and Benign myalgic encephalomyelitis.

(For ICD-11, a mechanism will be provided to identify whether an inclusion term is a synonym or a subclass.)

In June 2010, I reported that in May 2010, a change of hierarchy had been recorded in the ICD-11 iCAT Alpha drafting platform “Change History” and “Category Discussion Notes” for class: G93.3 Postviral fatigue syndrome.

See these two screenshots from the original iCAT Alpha drafting platform:

Image 1:

Image 2:

From current information in the Beta draft, it would appear that for ICD-11, the proposal is for a change of hierarchy between Postviral fatigue syndrome and Chronic fatigue syndrome with Chronic fatigue syndrome elevated to an ICD-11 Title term, with a Definition (not currently populated) and with potentially up to 12 other descriptive parameters, populated in accordance with the ICD-11 “Content Model.”

There are a number of terms listed under Synonyms to Title term Chronic fatigue syndrome including Benign myalgic encephalomyelitis and Postviral fatigue syndrome.

Mouse hover over the asterisk at the end of Benign myalgic encephalomyelitis and the following hover text displays, “This term is an inclusion term in the linearizations.”

Also listed under “Synonyms” are “chronic fatigue syndrome nos” and “chronic fatigue, unspecified” (both imported from current proposals for locating Chronic fatigue syndrome in Chapter 18: Symptoms and Signs in the forthcoming US specific, ICD-10-CM).

See this Beta drafting platform page:



There is currently no discrete ICD Title term listed for Postviral fatigue syndrome in either the Foundation Component or Linearization Morbidity view and no discrete ICD Title term for Benign myalgic encephalomyelitis.

It remains unconfirmed, but from the Beta draft as it currently stands, it suggests that for ICD-11:

  • Chronic fatigue syndrome is proposed to become the Chapter 06 Title term
  • Benign myalgic encephalomyelitis is specified as an Inclusion term to CFS under “Synonyms”
  • Postviral fatigue syndrome and a number of other terms are listed under “Synonyms” to CFS

ICD-11 terminology:

For definitions of Synonyms, Inclusions, Exclusions and other ICD-11 terminology see the iCAT Glossary:


Fibromyalgia (FM):

In ICD-10, Fibromyalgia is classified under:

Chapter XIII: Diseases of the musculoskeletal system and connective tissue > M79 Other soft tissue disorders > M79 Other soft tissue disorders, not elsewhere classified > M79.7 Fibromyalgia 

ICD-10 Version: 2010: http://apps.who.int/classifications/icd10/browse/2010/en#/M79.7

For ICD-11 Beta draft, Fibromyalgia is currently classified under:

Chapter 13: Diseases of the musculoskeletal system and connective tissue > Soft tissue disorders > Other soft tissue disorders > QG6 Other soft tissue disorders, not elsewhere classified > QG6.7 Fibromyalgia

FC: http://apps.who.int/classifications/icd11/browse/f/en#/http%3a%2f%2fwho.int%2ficd%23M79.7
LM: http://apps.who.int/classifications/icd11/browse/l-m/en#/http%3a%2f%2fwho.int%2ficd%23M79.7

Irritable bowel syndrome (IBS):

In ICD-10, Irritable bowel syndrome is classified under:

Chapter XI: Diseases of the digestive system > K55-K63 Other diseases of intestines > K58.0 Irritable bowel syndrome with diarrhoea > K58.9 Irritable bowel syndrome without diarrhoea > Irritable bowel syndrome NOS

ICD-10 Version: 2010: http://apps.who.int/classifications/icd10/browse/2010/en#/K58

For ICD-11 Beta draft, Irritable bowel syndrome is currently classified under:

Chapter 11: Diseases of the digestive system > Functional gastrointestinal disorders > FS6 Irritable bowel syndrome and other functional bowel disorders > FS6.1 Irritable bowel syndrome 

FC: http://apps.who.int/classifications/icd11/browse/f/en#/http%3a%2f%2fwho.int%2ficd%23K58
LM: http://apps.who.int/classifications/icd11/browse/l-m/en#/http%3a%2f%2fwho.int%2ficd%23K58

I shall continue to monitor the Beta drafting process and update on any significant developments for both ICD-11 Chapter 5 and Chapter 6 and for ICD11-PHC for the categories that are the focus of this post and post #190.
