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).

For ICD-11-PHC (the abridged version of ICD for use in primary care and low resource settings), it is also the intention not to retain the primary care disorder category F48 Neurasthenia.

Here are the references for the primary care version:

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

Submitted

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!
