Summary of responses from Dr Geoffrey Reed, WHO

On July 23, I submitted an analysis and four questions via the ICD-11 Beta drafting platform for the attention of the Managing Editors for Topic Advisory Group (TAG) Mental Health, the advisory group that is revising ICD-10’s Chapter V.

A copy has been posted in Dx Revision Watch Post #311: Questions raised on ICD-11 Beta draft re: Bodily distress disorder http://wp.me/pKrrB-3Yh

Comments and suggestions submitted by registered users of the ICD-11 Beta drafting platform are screened and forwarded to the appropriate TAG Managing Editors for review.

I also sent a copy of my comments to Dr Geoffrey Reed. Dr Reed is Senior Project Officer overseeing the revision of the ICD Mental and behavioural disorders chapter.

On July 24, I received a response from Dr Reed, via email.

Dr Reed’s responses do not address all the points I had raised via the Beta platform and in my covering email. I am providing a summary of selected of Dr Reed’s responses, below.

I had also drawn Dr Reed’s attention to the absence, since early 2013, of the three G93.3 terms from the public version of the Beta draft and collective concerns for ICD Revision’s failure, to date, to respond to multiple requests to provide an explanation for the continued absence of these terms from the Beta draft and to clarify ICD Revision’s intentions and proposals for the classification of these three ICD-10 terms within ICD-11 [i.e. chapter location(s), parent code(s), hierarchies, Definitions, Synonyms, Inclusion terms etc.].

+++
Dr Reed provided the following information on July 24:

The placement of ME and related conditions within the broader ICD-11 classification is still unresolved.

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.

That ME and related conditions be clearly identified as NOT being part of this section of the classification could be made absolutely clear through the use of exclusion terms.

However, Dr Reed will be unable to request that exclusion terms be added to relevant Mental and behavioural disorders categories (e.g., Bodily Distress Disorder) until the conditions that are being excluded exist in the classification. At such time, he would be happy to request exclusion terms.

ICD Revision is currently involved in testing the proposals of the ICD-11 Primary Care Consultation Group* in primary care settings around the world, in part to compare how they work with the proposals of the ICD-11 Expert Working Group on Somatic Distress and Dissociative Disorders**.

Whether the primary care proposal ends up capturing specific groups of patients in primary care who are likely to have underlying medical conditions will certainly be one of the issues for examination and further discussion. Study data would be used as a basis for modifying proposals.

That he considers my analysis is accurate.

That it is not WHO policy to make research protocols for field trial studies that are planned or currently being implemented publicly available for comment.

Details of the study methodology at the time the data are published are expected to be provided, in order that others may examine and critique the methodology, their interpretation of results and their subsequent decisions based on the studies.

Further modifications of the proposals will be based on data evaluation, and justifications made available.

In due course, ICD Revision will make more detailed diagnostic guidelines for all Mental and behavioural disorders available for review and comment before they are finalized, but ICD Revision is not yet ready to do that.

Dr Reed will notify me when that occurs, but anticipates this will be before the end of the year and considers there is plenty of time for review as the approval of ICD-11 is now currently planned for May, 2017.

Dr Reed’s purview does not extend to the section on classification of Diseases of the nervous system or other areas outside the Mental and behavioural disorders chapter, and is therefore unable to provide any information related to how these conditions will be classified in other chapters***.

He is unable to comment about the management of correspondence by other TAG groups**** and signposts to another member of WHO staff [a senior classification expert who had been copied into the joint organizations’ letter to WHO/ICD Revision, in March].

Footnotes:

* Back in 2012, the ICD-11 Primary Care Consultation Group (the PCCG) were proposing a disorder construct that presented a modified version of the Fink et al (2010) Bodily Distress Syndrome (BDS) construct which, at that point, the Primary Care group were proposing to call, “Bodily stress syndrome (BSS).”

The PCCG hasn’t published a progress report since 2012 and the group’s current proposals are not available for scrutiny. If a modified version of BDS is currently being proposed by the PCCG, it isn’t known what changes have been made to the group’s proposals since the Lam et al paper was published in 2012, a paper which is now in the public domain [1].

An editorial co-authored by Prof David Goldberg, in June 2013, implied that Prof Goldberg, at least, was advancing that BDS should be progressed to ICD-11 field testing. It is unclear from Dr Reed’s responses to what extent the PCCG’s most recent proposals correspond to the disorder descriptions and criteria for Fink et al’s, already operationalized, BDS, or whether the group has retained the “BSS” disorder name for the purposes of the field tests and a modified construct/criteria set.

+++
** In 2012, the ICD-11 Expert Working Group on Somatic Distress and Dissociative Disorders (the S3DWG) were proposing an alternative and divergent disorder construct that had good concordance with DSM-5’s Somatic symptom disorder, and poor concordance with Fink et al’s BDS [2].

Perversely, the S3DWG were proposing to call their disorder construct, “Bodily distress disorder (BDD)” – a term already used outside ICD Revision, interchangeably, with Bodily Distress Syndrome [3].

It is the S3DWG’s BDD disorder construct that has been entered into the ICD-11 Beta drafting platform.

The Beta draft entry for BDD has recently had characterizations inserted for three BDD severity specifiers: BDD, Mild; BDD, Moderate; BDD, Severe. This post (which was written before I received responses from Dr Reed) sets out these recent additions to the draft in the context of the two divergent sets of proposals: Definitions for three severities of Bodily distress disorder now inserted in ICD-11 Beta draft, July 19, 2014 http://wp.me/pKrrB-3X9

*** This February 8, 2014 post: http://wp.me/pKrrB-3IX tracks the history of the progression of the three ICD-10 G93.3 categories, PVFS, (B)ME and CFS within the ICD-11 drafting platform, from May 2010 to early 2013.

Under the subheading “So why have these three ICD-10 terms disappeared and why is ICD Revision reluctant to respond?” I have suggested a number of potential reasons for the current absence of these three terms from the Beta draft.

**** On March 17, a joint letter signed by Sonya Chowdhury, CEO, Action for M.E., Annette Brooke MP, Chair, All Party Parliamentary Group on M.E., The Countess of Mar, Chair, Forward M.E. and Dr Charles Shepherd, ME Association, was sent to key Topic Advisory Group for Neurology members and copied to WHO’s Dr Margaret Chan, Dr Geoffrey Reed and Dr Robert Jakob.

The letter had requested, inter alia, clarification for the absence of the three ICD-10 G93.3 terms, Postviral fatigue syndrome, Benign myalgic encephalomyelitis and Chronic fatigue syndrome from the public version of the ICD-11 Beta drafting platform.

Prior to early 2013, in the public version of the Beta draft, Chronic Fatigue Syndrome had been listed in the Beta Foundation Component as an ICD Title entity under the Diseases of the nervous system chapter, with Benign Myalgic encephalomyelitis specified as an Inclusion term to Title term CFS, and Postviral fatigue syndrome listed under Synonyms to Title term, CFS.

The joint letter can be read here:

At the July 1 meeting of the APPG on M.E. it was agreed that in the absence of a response, Annette Brooke MP (Chair) would follow up the correspondence. Minuted here (under 3 Matters arising; d) ICD-11):

http://www.meassociation.org.uk/2014/07/minutes-of-the-appg-on-me-meeting-and-the-agm-held-on-1-july-2014/

I have advised Sonya Chowdhury, Dr Charles Shepherd, Neil Riley and Jane Colby of Dr Reed’s responses and suggested that Annette Brooke MP is updated.

Bodily distress disorder, severe

Comments on title

Suzy Chapman 2014-Jul-23 – 14:01 UTC

Definitions for three uniquely coded severities for Bodily distress disorder: Mild; Moderate; Severe, have recently been inserted into the Beta draft.

The Definition for Bodily distress disorder (BDD) and its three severity characterizations appears to be based on the BDD disorder descriptions in the 2012 Creed, Gureje paper: Emerging themes in the revision of the classification of somatoform disorders [1].

As conceptualized by the ICD-11 Expert Working Group on Somatic Distress and Dissociative Disorders (S3DWG), BDD is proposed to replace the seven ICD-10 Somatoform disorders categories F45.0 to F45.9, and F48.0 Neurasthenia.

The S3DWG’s BDD eliminates the requirement that symptoms be “medically unexplained” as the central defining feature; focuses on identification of positive psychobehavioural responses (excessive preoccupation with bodily symptoms, unreasonable illness fear, frequent or persistent healthcare utilization, activity avoidance for fear of damaging the body) in response to any (unspecific) persistent, distressing, single or multiple bodily symptom(s), resulting in significant impairment of functioning or frequent seeking of reassurance; makes no assumptions about aetiology, and in “[d]oing away with the unreliable assumption of its causality, the diagnosis of BDD does not exclude the presence of (…) a co-occurring physical health condition.”

The S3DWG’s BDD has no requirement for symptom counts, or for symptom patterns or symptom clusters from body or organ systems, which describes a disorder framework with good concordance with DSM-5 Somatic Symptom Disorder (SSD).

According to the Beta draft, BDD’s three severity specifiers are proposed to be characterized on the basis of the extent to which responses to persistent, distressing bodily symptoms are perceived as excessive and on the degree of impairment, not on the basis of number of bodily symptoms and number of body or organ systems affected.

In comparison, psychobehavioural responses do not form part of Fink et al’s (2010) Bodily Distress Syndrome criteria. BDS’s criteria and two severities are based on symptom patterns from body systems (a BDS Modest, single-organ type and a BDS Severe, Multi-organ type).

In 2012, the Lam et al paper [2], set out emerging proposals for the ICD-11 Primary Care Consultation Group’s (PCCG) recommendations for a “Bodily stress syndrome (BSS).”

The PCCG’s proposals described a disorder construct that had good concordance with Fink et al’s Bodily Distress Syndrome, drawing heavily on Fink et al’s criteria set. Although at that point, the PCCG proposed to incorporate some SSD-like psychobehavioural features within their tentative criteria. The PCCG appeared to be proposing a modified version of the Fink et al (2010) BDS construct.

In an Ivbijaro G, Goldberg D (June 2013) editorial [3], the co-authors advance the position that the forthcoming revision of ICD provides an opportunity to include BDS in a revised classification for primary care. According to this June 2013 editorial, the PCCG’s proposal for a modified BDS disorder construct, which it had earlier proposed to call “Bodily stress syndrome (BSS),” appears to have been revised to using the Fink et al “Bodily distress syndrome (BDS)” term.

The editorial implies that BDS (which subsumes the so-called “functional somatic syndromes,” CFS, ME, IBS, Fibromyalgia, chronic pain disorder, MCS and some others, under a single, overarching disorder) was expected to be progressing, imminently, to ICD-11 field trials.

(A revision of the earlier BSS disorder name is not discussed within the editorial; nor whether any modifications to, or deviance from a “pure” BDS construct and criteria were being recommended for the purposes of field testing; nor are the alternative proposals of the S3DWG referenced or discussed; nor are the views of the Revision Steering Group on either set of proposals discussed.)

According to Lam et al (2012) and Ivbijaro and Goldberg (June 2013), the model proposed is that of “autonomic over-arousal,” which the authors consider may be responsible for most or all of the somatic symptoms that are experienced.

Again, compare with the S3DWG’s BDD construct, which makes no assumptions about aetiology and does not exclude the presence of a co-occurring physical health condition, whereas, for both Lam et al’s 2012 BSS and for Fink et al’s BDS, “If the symptoms are better explained by another disease, they cannot be labelled BDS.”

Potential for confusion between divergent disorder constructs:

The term “Bodily distress disorder” and the term “Bodily distress syndrome” (Fink et al, 2010), which is already operationalized in Denmark in research and clinical settings, are often seen being used interchangeably in the literature. For example, in this very recent editorial by Rief and Isaac [4]. Also in papers by Fink and others from 2007 onwards [5].

However, the S3DWG’s defining of a “Bodily distress disorder” construct has stronger conceptual alignment and criteria congruency with DSM-5’s SSD and poor conceptual and criteria congruency with Fink et al’s BDS. That SSD and BDS are very different concepts is acknowledged by Fink, Creed and Henningsen [6] [7].

Although the 2013 Ivbijaro and Goldberg editorial implies that Fink et al’s BDS construct was going forward to ICD-11 field testing, it is the S3DWG’s Bodily distress disorder name and construct that has been entered into the Beta draft – the construct that has stronger conceptual alignment with DSM-5’s SSD.

So the current proposals and intentions for field testing a potential replacement for the SDs remain unclear. This is severely hampering professional and consumer stakeholder scrutiny, discourse and input.

Four questions for TAG Mental Health Managing Editors:

1. Have the S3DWG sub working group, the PCCG working group and the Revision Steering Group reached consensus over a potential replacement framework and disorder construct for ICD-10’s Somatoform disorders and F48.0 Neurasthenia, and the ICD-10-PHC categories: F45 Unexplained somatic symptoms/medically unexplained symptoms, and F48 Neurasthenia?

2. Which recommendations are being progressed to international field testing and does ICD-11 intend to release the protocol or other information on finalized characteristics, diagnostic guidelines, criteria, inclusions, exclusions, differential diagnoses etc, that are planned to be used for the field tests and which would provide the level of detail lacking in the public version of the Beta drafting platform?

3. If, in the context of ICD-11 usage, the S3DWG working group’s proposal for a replacement for the Somatoform disorders remains for a disorder model with good concordance with the DSM-5 SSD construct, what is the rationale for proposing to name this disorder “Bodily distress disorder”?

4. Have the S3DWG, PCCG and Revision Steering Group given consideration to the significant potential for confusion if its replacement construct for the Somatoform disorders has greater conceptual alignment with the SSD construct but is assigned a disorder name that sounds very similar to, and is already being used interchangeably with an operationalized but divergent construct and criteria set?

This report updates on recent additions to the listing for Bodily distress disorder in the public version of the ICD-11 Beta draft.

This is an edited version of the report published on July 19.

+++
Bodily distress disorder (BDD) is a new, single diagnostic category that has been proposed for ICD-11. It is intended to subsume the seven ICD-10 Somatoform disorders categories F45.0 – F45.9, and F48.0 Neurasthenia.

Bodily distress disorder (BDD) is the term that has been entered into the Beta drafting platform since February 2012.

It is the term and disorder construct that has been proposed by the ICD-11 Expert Working Group on Somatic Distress and Dissociative Disorders (S3DWG), which is chaired by Professor Oye Gureje [1].

Note: the term Bodily stress syndrome (BSS) (Lam et al, 2012) is an alternative disorder term and diagnostic construct that has been proposed by the ICD-11 Primary Care Consultation Group (PCCG), which is chaired by Professor Sir David Goldberg [2].

The disorder term and construct Bodily distress syndrome (BDS) has also been advanced for ICD-11 in a June 2013 editorial by Ivbijaro G and Goldberg D [3].

Neither of the terms Bodily stress syndrome (BSS) or Bodily distress syndrome (BDS) has been entered into the ICD-11 Beta draft.

+++
ICD-11 Beta drafting platform (public version):

A Definition for category Bodily distress disorder was inserted into the Beta draft in late January 2014.

At that point, no definitions or characterizations for any of the uniquely coded BDD severity specifiers (currently, BDD, mild; BDD, moderate; BDD, severe) had been inserted.

+++
How is BDD being defined for the purposes of ICD-11?

The psychological and behavioural features that characterize Bodily distress disorder, as currently defined in the Beta draft, are drawn from the disorder conceptualizations in the 2012 Creed, Gureje paper on emerging proposals for the revision of the classification of somatoform disorders [1].

This paper sits behind a paywall but I have had a copy since it was first published.

The paper describes a disorder model that has poor concordance with Fink et al’s Bodily Distress Syndrome construct.

The 2012 Creed, Gureje paper defines BDD as:

“a much simplified set of criteria”;

eliminates the requirement that symptoms be “medically unexplained” as the central defining feature;

focuses on identification of positive psychobehavioural responses (excessive preoccupation with bodily symptoms, unreasonable illness fear, frequent or persistent healthcare utilization, activity avoidance for fear of damaging the body) in response to any (unspecific) persistent, distressing, single or multiple bodily symptom(s), resulting in significant impairment of functioning or frequent seeking of reassurance;

makes no assumptions about aetiology and in “[d]oing away with the unreliable assumption of its causality the diagnosis of BDD does not exclude the presence of (…) a co-occurring physical health condition”;

has no requirement for symptom counts, or for symptom patterns or symptom clusters from body or organ systems

– which describes a disorder framework into which DSM-5′s “Somatic Symptom Disorder (SSD)” could potentially be integrated, facilitating harmonization between a replacement for the ICD-10 Somatoform disorders and DSM-5’s new SSD.

+++
Whereas, Fink et al’s 2010 Bodily Distress Syndrome criteria are based on impairment and symptom patterns from body systems. Positive psychobehavioural features do not form part of the Fink et al criteria [4–6].

For ICD-11’s BDD, patients may be preoccupied with any bodily symptoms and the presence of a co-occurring physical health condition is not an exclusion.

But for Fink et al’s BDS, “If the symptoms are better explained by another disease, they cannot be labelled BDS.”

BDD’s three severity specifiers are proposed to be characterized on the basis of the extent to which responses to persistent, distressing symptoms are perceived as excessive and on degree of impairment, not on the basis of the number of bodily symptoms and the number of body or organ systems that are affected by the disorder.

In contrast, BDS’s two severities are based on symptom patterns (a BDS Modest, single-organ type and a BDS Severe, Multi-organ type).

Both BDD and BDS are intended to subsume the Somatoform disorders and Neurasthenia.

But BDS seeks to arrogate the so-called “functional somatic syndromes,” CFS, ME, IBS, Fibromyalgia, chronic pain disorder, MCS and some others, and subsume them under a single, overarching BDS diagnosis [6].

So although the BDD and BDS disorder names sound very similar (and the terms are sometimes seen used interchangeably), as defined in the 2012 Creed, Gureje paper and as defined by the recently inserted Beta draft Definitions, ICD-11’s BDD and Fink et al’s BDS present divergent constructs*.

It is the ICD-11 Primary Care Consultation Group‘s 2012 proposals for a “Bodily stress disorder” [2] that had stronger conceptual alignment and criteria congruency with Fink et al’s BDS.

*Discussions between Profs Creed and Fink during the Research Clinic for Functional Disorders Symposium presentations, Aarhus University Hospital, May 15, 2014, noted that Fink et al’s BDS and DSM-5’s SSD are “very different concepts.” That SSD and BDS are divergent constructs is also discussed in: Medically Unexplained Symptoms, Somatisation and Bodily Distress: Developing Better Clinical Services, Francis Creed, Peter Henningsen, Per Fink (Eds), Cambridge University Press, 2011.

Definition

Bodily distress disorder is characterized by high levels of preoccupation regarding bodily symptoms, unusually frequent or persistent medical help-seeking, and avoidance of normal activities for fear of damaging the body. These features are sufficiently persistent and distressing to lead to impairment in personal, family, social, educational, occupational or other important areas of functioning. The most common symptoms include pain (including musculoskeletal and chest pains, backache, headaches), fatigue, gastrointestinal symptoms, and respiratory symptoms, although patients may be preoccupied with any bodily symptoms. Bodily distress disorder most commonly involves multiple bodily symptoms, though some cases involve a single very bothersome symptom (usually pain or fatigue).

Definition 

Bodily distress disorder, mild is a form of Bodily distress disorder in which there is excessive attention to bothersome symptoms and their consequences, which may result in frequent medical visits. The person is not preoccupied with the symptoms (e.g., spends less than an hour per day focusing on them). Although the individual expresses distress about the symptoms and they may have some impact on his or her life (e.g., strain in relationships, less effective academic or occupational functioning, abandonment of specific leisure activities) there is no substantial impairment in the person’s personal, family, social, educational, occupational, or other important areas of functioning.

Bodily distress disorder, moderate is a form of bodily distress disorder in which there is persistent preoccupation with bothersome symptoms and their consequences (e.g., spends more than an hour a day thinking about them), typically associated with frequent medical visits such that the person devotes much of his or her energy to focusing on the symptoms and their consequences, with consequent moderate impairment in personal, family, social, educational, occupational, or other important areas of functioning (e.g., relationship conflict, performance problems at work, abandonment of a range of social and leisure activities).

Definition

Bodily distress disorder, severe is a form of bodily distress disorder in which there is pervasive and persistent preoccupation to the extent that the symptoms may become the focal point of the person’s life, typically requiring extensive interactions with the health care system. Preoccupation with the experienced symptoms and their consequences causes serious impairment in personal, family, social, educational, occupational, or other important areas of functioning (e.g., unable to work, alienation of friends and family, abandonment of nearly all social and leisure activities). The person’s interests may become so narrow so as to focus almost exclusively on his or her bodily symptoms and their negative consequences.

What will ICD-11 be field testing?

Field testing of a potential replacement for the existing ICD-10 Somatoform disorders framework is expected to be conducted over the next year or two. Disorders that survive the ICD-11 PHC field tests will require an equivalent disorder in the main ICD-11 classification.

So whatever replaces the existing ICD-10 PHC categories, F45 Unexplained somatic symptoms/medically unexplained symptoms and F48 Neurasthenia, (which is also proposed to be eliminated for the ICD-11 primary care version), will need an equivalent disorder in the main classification.

International field tests across a range of primary care settings had been anticipated to start from June, last year, but there were reported delays. It isn’t known whether consensus has been reached yet over disorder construct and diagnostic criteria for use in the field tests, or whether field testing is now underway.

I cannot confirm whether ICD-11 intends to release a protocol into the public domain for whatever construct it plans to field test, or may already be field testing.

Currently, there is no publicly available protocol or other information on finalized characteristics, diagnostic guidelines, criteria, inclusions, exclusions, differential diagnoses etc. that are planned to be used for the field tests which would provide the level of detail lacking in the public version of the Beta drafting platform.

+++

So which construct does ICD-11 Revision Steering Group favour?

Although BDD (and now its three severities) have been defined within the Beta draft, much remains unclear for proposals for the revision of this section of ICD-11 Mental and behavioural disorders.

The ICD-11 Primary Care Consultation Group’s alternative 2012 Bodily stress syndrome (BSS) construct – a near clone of Fink et al’s BDS criteria but with some SSD-like psychobehavioural responses tacked on – isn’t the construct that is entered and defined within the Beta draft.

In June 2013, Prof Gabriel Ivbijaro (not, himself, a member of the PCCG) and Prof Sir David Goldberg (who chairs the PCCG) published a joint editorial in Mental Health in Family Medicine, the official journal of The World Organization of Family Doctors (Wonca) Working Party on Mental Health, for which Prof Ivbijaro is Editor in Chief.

The authors advance the position that the forthcoming revision of ICD “provides an opportunity to include BDS in a revised classification for primary care” and imply that BDS (at least at that point) was progressing, imminently, to ICD-11 field trials.

This brief editorial was embargoed from June 2013 to June 2014 and I was unable to obtain a copy until last month, but you can read it now for free and in full here: Bodily distress syndrome (BDS): the evolution from medically unexplained symptoms (MUS).

Note, firstly, that the editorial does not declare Professor Goldberg’s interest as chair of the ICD-11 Primary Care Consultation Group.

It does not clarify whether the views and opinions expressed within the editorial represent the views of the authors or are the official positions of the PCCG working group, or of the International Advisory Group for the Revision of ICD-10 Mental and Behavioural Disorders, or of the ICD-11 Revision Steering Group (RSG), or of any committees on which co-author, Prof Ivbijaro, sits or of any bodies to which Prof Ivbijaro is affiliated.

No publicly posted progress reports are being issued by ICD-11 or by either of the two groups making recommendations for the revision of this section of ICD and I do not have a second source that confirms the status of proposals as they stood in June 2013.

But taking the editorial at face value, it would appear that the PCCG had revised its earlier proposals for a BSS construct (that drew heavily on Fink et al’s BDS criteria but had included the requirement for some psychobehavioural responses) and were now recommending that the Fink et al BDS construct and criteria should progress for ICD-11 PHC field testing and evaluation, that is, using the same disorder name and (presumably) the same criteria set that is already operationalized in research and clinical settings, in Denmark.

(The rationale for the apparent revision of the earlier BSS disorder name is not discussed within the editorial; nor whether any modifications to, or deviance from a “pure” BDS construct and criteria were being recommended for the purposes of ICD-11 field testing.)

The editorial doesn’t clarify whether the PCCG, the S3DWG and the ICD-11 Revision Steering Group (RSG) had reached consensus – it does not mention the alternative proposals of the S3DWG, at all, or discuss what is entered into the Beta draft, or discuss the views and preferences of the Revision Steering Group for any of recommendations made by the two advisory groups, to date.

It is unclear whether a “pure” BDS construct (as opposed to the PCCG’s earlier BSS modification) had already gained Revision Steering Group approval for progressing to field testing, at the point the editorial was drafted, or whether Prof Goldberg was using this Wonca house journal as a platform on which to promote his own opinions and expectations, in a purely personal capacity.

Crucially, it doesn’t explain why, if a BDS-like construct were anticipated to be progressed to field trials in the second half of 2013, it is the S3DWG’s Bodily distress disorder diagnostic construct that has been listed and defined in the Beta draft for Foundation, Mortality and Morbidity, Primary Care High Resource, Primary Care Low Resource linearizations – not the PCCG’s 2012 BSS modification, or the “pure” BDS that Prof Goldberg evidently champions.

As a source of information on the current status of proposals for the revision of the Somatoform disorders this June 2013 editorial is problematic (and now also over a year out of date).

I suspect the politics between the 12 member PCCG (which includes Marianne Rosendal*), the 17 member S3DWG and the ICD-11 Revision Steering Group are intensely fraught given Professor Goldberg’s agenda for the revision of the Somatoform disorders, since fitting BDS into ICD-11 hasn’t proved to be the shoo in that Fink, Rosendal and colleagues had hoped for**, and given that BDS cannot be harmonized with DSM-5’s SSD, as they are conceptually divergent.

*Dr Marianne Rosendal (Department of Public Health, Aarhus University), who has published with Prof Per Fink, is the European representative on WONCA’s International Classification Committee. The vice-chair of the PCCG is Dr Michael Klinkman, a GP who represents WONCA (World Organization of Family Doctors). Dr Klinkman is current convenor of WONCA’s International Classification Committee (WICC) that is responsible for the development of ICPC-2.
**Presentation, Professor Per Fink, March 19, 2014 Danish parliamentary hearing on Functional Disorders. Prof Fink stated that he and his colleagues had tried to get WHO to incorporate a section for a special group of disorders where BDS could be placed that was located neither in psychiatry nor in general medicine, but had not been successful.

Requests for clarification repeatedly stonewalled:

ICD Revision has been asked several times, via the Beta drafting platform, to clarify current proposals for the framework and disorder construct for a replacement for the ICD-10 Somatoform disorders and to clarify which construct it intends to take forward to field testing. ICD Revision has also been asked to comment on the following:

“If, in the context of ICD-11 usage, the S3DWG working group’s proposal for a replacement for the Somatoform disorders remains for a disorder model with good concordance with DSM-5′s SSD construct, what is the rationale for proposing to name this disorder “Bodily distress disorder”?

“Have the S3DWG, PCCG and Revision Steering Group given consideration to the significant potential for confusion if its replacement construct for the Somatoform disorders has greater conceptual alignment with the SSD construct but is assigned a disorder name that sounds very similar to, and is already being used interchangeably with an operationalized but divergent construct and criteria set?”

No response has been forthcoming.

Lack of publicly posted progress reports by both working groups, confusion over the content of the Beta draft and ICD Revision’s failure to respond to queries from stakeholders is hampering stakeholder scrutiny, discourse and input. It is time clinicians, researchers, allied professionals and advocacy organizations demanded transparency from ICD Revision around current proposals and field trial intentions.

September symposium presentation on BDD:

In September, Professor Oye Gureje (who chairs the ICD-11 Expert Working Group on Somatic Distress and Dissociative Disorders), will be presenting on Proposals and evidence for the ICD-11 classification of Bodily Distress Disorders, as part of series of symposia on the development of the ICD-11 chapter for mental and behavioural disorders, at the World Psychiatric Association XVI World Congress, in Madrid, Spain, 14–18 September 2014 [7].

Unfortunately, I cannot attend this symposium presentation but would be pleased to hear from anyone who may be planning to attend.

September 2013 meeting Diagnosis Agenda

The fall meeting of the ICD-9-CM/PCS Coordination and Maintenance Committee took place on September 18–19.

The Diagnosis Agenda had included the proposals to add the new DSM-5 disorder terms: Somatic symptom disorder and Illness anxiety disorder to the ICD-10-CM Tabular List and the Alphabetical Index.

Note that the proposal was to add the terms as Inclusion Terms under existing ICD-10-CM Chapter 5 codes, not to create unique new codes for these two terms, or to replace or subsume any existing categories:

March 2014 meeting Diagnosis Agenda

The spring C & M Committee meeting took place on March 19–20, 2014. I was unable to attend either meeting as I live in the UK, and it is not feasible for me to participate in these public meetings via phone link.

The March Diagnosis Agenda included reiteration of the September proposal to add Somatic symptom disorder to the ICD-10-CM Alphabetical Index, coded to F45.1. (But did not include a resubmission to add to the Tabular List.) The reason for its reiteration in the March Agenda is unclear.

When the March Agenda requests for additions and modifications to the Tabular List were reached, CDC’s Beth Fisher had remarked that some of the proposals for additions to the Tabular List may have been proposed at the September 2013 meeting (though no explanation was given for why some of these September proposals were being duplicated in the March Agenda).

Evidently some Index proposals from the September meeting were also duplicated in the March Agenda, including SSD, but not Illness anxiety disorder.

There were no comments or queries from the floor in relation to proposals for SSD. There were no queries about whether NCHS decisions had already been reached on the requests for additions and modifications submitted via the September meeting.

It remains unclear whether the duplications in the March Agenda were due to administrative oversight, were being included for procedural reasons, or were being re-presented in response to NCHS committee decisions made following the September meeting, to which APA, but not the public at large, might be party to. (The outcome of both the September and March proposals may not be evident until 2015, when the next Addendum is posted.)

F45.1 (SSD) and F45.21 (Illness anxiety disorder) are the ICD-10-CM codes to which these two new APA disorders are already cross-walked in the DSM-5:

If NCHS rubber stamps the addition of Somatic Symptom Disorder to the ICD-10-CM it could leverage future proposals (either by NCHS/CMS or by external requestors) for the replacement of some or all of the existing Somatoform disorders categories with this new, single SSD diagnostic construct, in order to bring ICD-10-CM in line with DSM-5.

There are implications for ICD-11, too. Once SSD is inserted into ICD-10-CM, the presence of this term within the U.S. adaptation of ICD-10 may make it easier for the ICD-11 Revision Steering Group to justify proposals to replace the existing ICD-10 Somatoform disorders categories with a single, new ICD construct incorporating SSD-like characteristics, to facilitate harmonization between ICD-11 and DSM-5 disorder terms and diagnostic criteria.

Diagnosis Agenda Page 89: Under “Proposed Index Modifications”: Add Somatic symptom disorder to ICD-10-CM Alphabetical Index (F45.1)

Proposal requestor: Unspecified

Comment submitted by Suzy Chapman DipAD, [Address redacted]

Date submitted: June 15, 2014

I write in objection to the proposed addition of Somatic symptom disorder to the ICD-10-CM Alphabetical Index for consideration for implementation on October 1, 2015 [or on and after October 1, 2016 after the partial code freeze has ended, as applicable].

This March 19-20, 2014 meeting proposal duplicates the request at the September 18-19, 2013 meeting for the addition of Somatic symptom disorder to the ICD-10-CM Index (and to the Tabular List) as an Inclusion Term to existing code, F45.1 Undifferentiated somatoform disorder.

Somatic symptom disorder is a new disorder conceptualization created by the American Psychiatric Association (APA) for DSM-5.

For DSM-5, the Somatoform Disorders have been dismantled. Four DSM-IV categories: somatization disorder [300.81], some presentations of hypochondriasis [300.7], pain disorder, and undifferentiated somatoform disorder [300.82] are eliminated and replaced with a single new diagnosis, Somatic symptom disorder (SSD), cross-walked in DSM-5 to ICD-9 300.82 (ICD-10-CM F45.1).

The Somatic symptom disorder construct de-emphasizes “medically unexplained” as the central defining feature of this disorder group. Instead, the focus shifts away from somatic symptoms to emotional, cognitive and behavioral disturbances and “maladaptive” responses to symptoms: high levels of health anxiety; disproportionate and persistent concerns about the medical seriousness of the symptom(s); or an excessive amount of time and energy devoted to symptoms and health concerns.

Symptoms may or may not be associated with another medical condition: SSD allows for the application of a mental disorder diagnosis in patients with “established general medical conditions or disorders” like diabetes, heart disease and cancer or presenting with “somatic symptoms of unclear etiology” if the clinician considers the patient otherwise meets the new criteria.

To meet the requirements for DSM-IV’s Somatization disorder, a rigorous criteria set needed to be fulfilled: a history of many medically unexplained symptoms before the age of thirty, resulting in treatment sought or psychosocial impairment. And a high diagnostic threshold: a total of eight or more medically unexplained symptoms from four, specified symptom groups, with at least four pain, two gastrointestinal, one psychosexual and one pseudoneurological symptom.

In DSM-5, the requirement for eight symptoms has been dropped to just one or more persistent, non specific, distressing somatic symptoms and the clinician’s perception of “excessive” or “maladaptive” response to the symptom or symptoms.

• These changes for DSM-5 represent a radical restructuring of the DSM-IV Somatoform disorders framework and introduce a new construct for which much remains to be determined.

On Day Two of the September 18-19, 2013 ICD-9-CM Coordination and Maintenance Committee meeting, Dr Darrel Regier had presented and discussed rationales, coding proposals and timings for six new DSM-5 disorders that APA has proposed for insertion into ICD-10-CM. But the Diagnosis Agenda proposals to add the new DSM-5 Somatic symptom disorder and Illness anxiety disorder category terms as inclusion terms to ICD-10-CM did not form part of Dr Regier’s presentation.

As it was unspecified within the Diagnosis Agenda and during the meeting presentations, it is unclear whether these two proposals are being requested by APA, by NCHS/CMS, or by other parties or individuals.

+++
• My first concern is that no description of Somatic symptom disorder, no rationale for why this ICD-10-CM modification is needed (including clinical relevancy) and no supporting clinical and literature references for the validity of Somatic symptom disorder as a new disorder were published in the Diagnosis Agenda for either the September or March meeting.

At the public meeting, no presentation had been made on behalf of APA, or by representatives of NCHS or CMS, or by anyone else for the specific Agenda proposal to add Somatic symptom disorder as an inclusion term under an existing ICD-10-CM Somatoform disorders code and there was no discussion of this proposal during the course of the meeting [1][2].

There is an expectation that the committees overseeing the development and revision of the draft for ICD-10-CM will give due consideration to the applicability, clinical utility, safety and reliability of any proposal for the inclusion of a new disorder construct before granting approval for its addition to the Tabular List and Index, and that the comments and objections received during the public response period will also be considered. The lack of rationales and references for supportive evidence provided by the requestors hinders public participation in the response process.

• The absence from the Diagnosis Agendas and meeting presentations of rationales, clinical relevancy and supporting clinical and literature references to enable proper public scrutiny, consideration and informed responses to this proposal should disqualify Somatic symptom disorder from consideration for implementation once the partial code freeze has lifted.

+++
The burden of proof before introducing any new diagnosis into a classification system is that it has a favourable risk to benefit ratio. This new diagnostic construct created by APA and introduced into DSM-5 merits the same level of scrutiny and risk to benefit evaluation as would be expected to be applied to any proposed new disorder/disease that is under consideration for inclusion in any chapter of ICD, whether this is for the updating of the ICD-10-CM draft, updating of WHO’s ICD-10, updating of clinical modifications of ICD-10, or drafting of ICD-11.

A number of papers have noted the paucity of rigorous evidence for the validity, reliability, acceptability, safety and utility of the application of the Somatic symptom disorder construct in adults and children across diverse clinical settings and by a spectrum of health and allied professionals. There is no significant body of published research on the epidemiology, clinical characteristics or treatment of the Somatic symptom disorder construct [3][4][5].

In a paper published in the Journal of Psychosomatic Research, September 2013, the DSM-5 Somatic symptom disorder Work Group concedes the lack of clinical evidence for its new construct and acknowledges the “small amount of validity data concerning SSD” and “that much remains to be determined” about the utility and reliability of the specific SSD criteria and its thresholds when applied in busy, general clinical practice, and there are “vital questions that must be answered” as they go forward [6].

• As an under researched, poorly validated disorder construct, Somatic symptom disorder does not meet NCHS/CMS criteria for new diseases/new technology procedures, and any minor revisions to correct reported errors in these classification and should be rejected for consideration for implementation during a partial code freeze and also rejected for consideration for implementation on or after October 1, 2015 [October 1, 2016].

+++
Concerns for the looseness of the Somatic symptom disorder definition and the ease with which these new criteria can be met have been discussed in a number of published papers and commentaries [7][8][9][10].

The over-inclusiveness of the SSD diagnosis is borne out by the results of the DSM-5 field trial study reported by Joel E Dimsdale, MD, chair of the Somatic symptom disorder Work Group, at the 2012 annual meeting of the American Psychiatric Association.

15% of the ‘diagnosed illness’ study group, comprising patients with cancer or coronary disease, were caught by SSD and would meet the criteria for application of an additional mental disorder diagnosis.

26% of the ‘functional somatic’ study group, comprising patients with irritable bowel syndrome or chronic widespread pain, met the SSD criteria.

SSD has a high false positive rate – capturing 7% of the ‘healthy’ field trial control group.

It is disturbing that the SSD Work Group (which had included no primary care physicians or pediatricians) appears not to have undertaken any field trials into the safety of application of the SSD criteria in children and adolescents.

NCHS/CMS provides no references for data for the application of SSD in children within the Diagnosis Agenda, although the DSM-5 text clearly indicates APA’s intention that SSD is a diagnosis that may also be applied to children with persistent, distressing somatic symptoms.

+++
Potential implications for the application of a diagnosis of SSD:

I am not persuaded that the new SSD diagnosis can be safely applied outside the optimal conditions of field trials, in settings where practitioners may not necessarily have adequate time for, or instruction in administration of diagnostic assessment tools, and where decisions to code or not to code may hang on the arbitrary and subjective perceptions of a wide range of end-users who may lack clinical training in the application of mental disorder criteria.

Misapplication of highly subjective and loose, easily met criteria, especially in busy primary care practice, may result in inappropriate diagnoses of mental disorder and inappropriate medical decision making, with considerable implications for patients [11].

A recent study (Plouvier et al, 2014) found more frequent presentation with functional somatic symptoms and multiple prodromal symptoms in the two year period prior to diagnosis with Parkinson’s disease than controls [12].

Incautious application or a pre-existing diagnosis of SSD in the patient’s notes may blunt clinician alertness and receptivity to emerging prodromal symptomotology of serious disease.

Patients with chronic, multiple bodily symptoms due to rare diseases, difficult to diagnose conditions, or multi system diseases like Behçet’s disease, for which it can take several years to arrive at a diagnosis, may be especially vulnerable to missed diagnosis or to misdiagnosis with a mental disorder, impeding access to testing, investigations, timely diagnosis and early intervention (and may result in increased claims against practitioners for medical negligence).

With the elimination of the requirement that symptoms be “medically unexplained” and inclusion of the presence of a co-occurring physical health condition, a mental disorder diagnosis of SSD can be applied as a “bolt-on” to any chronic medical diagnosis: to patients with diabetes, angina, cancer, MS, cardiovascular disease, ME and CFS, IBS, chronic widespread pain (aka fibromyalgia), chronic pain conditions or persistent symptoms of unclear etiology.

Patients with Chronic fatigue syndrome (CFS), “almost a poster child for medically unexplained symptoms as a diagnosis,” according to the SSD Work Group chair, or with chronic Lyme disease, Gulf War illness, chemical injury and chemical sensitivity; women with potential symptoms of gynecological disease, like ovarian cancer – already often late-diagnosed because persistent symptoms had been initially dismissed as IBS or a menopausal-related bladder complaint; or women with endometriosis or interstitial cystitis may be particularly vulnerable to misapplication or misdiagnosis with a mental health disorder under SSD criteria.

(There is also a Brief somatic symptom disorder in DSM-5, cross-walked to ICD-9 F45.8, that can be applied where duration of symptoms is less than 6 months. Just one somatic symptom and one “disproportionate” psychobehavioral response to that symptom, for less than 6 months chronicity, now ticks the box for a mental health diagnosis.)

There has been considerable opposition to the introduction of this new, poorly tested construct into the DSM-5 amongst patients, carers, advocates, consumer organizations, mental health practitioners and clinicians and considerable concern for the implications for diverse patient populations that the Somatic Symptom Disorder category will provide a “dustbin diagnosis” for the so-called “functional somatic syndromes,” for those living with chronic pain and for patients with persistent, but as yet undiagnosed, symptoms of disease.

• NCHS/CMS has published no independent field trial data and provided no rationales or clinical and literature references to inform public responses.

Given the lack of published evidence for the validity and safety of SSD, there is insufficient basis for the approval of SSD for inclusion within ICD-10-CM and it would be scientifically unsafe, premature and against the public interest to include this new diagnostic construct within ICD.

The proposal for the addition of Somatic symptom disorder to the ICD-10-CM as an inclusion term to the Index and Tabular List should be rejected. There should be no implementation in October 2016 as an inclusion term to F45.1, or to any other existing code, or with a unique code created.

+++
Appendix:

Incautious, inept application of criteria resulting in a “bolt-on” psychiatric diagnosis of Somatic symptom disorder has far-reaching implications for diverse patient populations:

Application of highly subjective and difficult to measure criteria could potentially result in misdiagnosis with a mental disorder, misapplication of an additional diagnosis of a mental disorder or missed diagnoses through dismissal and failure to investigate new or worsening somatic symptoms.

Patients with cancer and life threatening diseases may be reluctant to report new symptoms that might be early indicators of recurrence, metastasis or secondary disease for fear of attracting a diagnosis of SSD or being labelled as “catastrophizers.”

Application of an additional diagnosis of SSD may have implications for the types of medical investigations, tests and interventions that clinicians are prepared to consider and for which insurers are prepared to fund.

Application of an additional diagnosis of SSD may impact payment of employment, medical and disability insurance and the length of time for which insurers are prepared to pay out.

 An SSD diagnosis may negatively influence the perceptions of agencies involved with assessment and provision of social care packages, disability adaptations, workplace accommodations, provision of education arrangements tailored to the needs of children with chronic illness, and the perceptions of medical staff during hospital and accident and emergency admission, and prejudice future employment options.

Patients prescribed psychotropic drugs for perceived unreasonable levels of “illness worry” or “excessive preoccupation with symptoms” may be placed at risk of iatrogenic disease or subjected to inappropriate and costly behavioural therapies.

Multi-system diseases like Multiple Sclerosis, Behçet’s disease or Systemic lupus can take several years before a diagnosis is arrived at. In the meantime, patients with chronic, multiple somatic symptoms who are still waiting for a diagnosis would be vulnerable to being labelled with a mental disorder.

The burden of the DSM-5 changes to Somatoform disorders will fall particularly heavily upon women who are more likely to be casually dismissed when presenting with physical symptoms and more likely to be prescribed inappropriate antidepressants and anti-anxiety medications for them.

Somatic symptom disorder allows for the application of a diagnosis of SSD in children and where a parent is perceived as being excessively concerned about a child’s symptoms.

The diagnostic term “Somatic Symptom Disorder” is already being applied to children despite the lack of a body of evidence for the reliability, safety and validity of the DSM-5 SSD criteria [13].

I am deeply concerned that NCHS/CMS is considering inclusion of a new diagnostic term within ICD when no studies have been carried out into the safety of its application in children and adolescents.

Families caring for children and young people with any chronic disease or condition may be placed at increased risk of wrongful accusation of “over-involvement” with their child’s symptomatology.

Where a parent is perceived as responsible for, or encouraging maintenance of “sick role behavior” or “secondary gains” in a child, this can trigger social services investigation, or court intervention for the forced removal of a sick child out of the home environment and into foster care or in-patient rehabilitation, or placement of the child on the “at risk register.”

This is already happening to families in the U.S., UK and Europe with a child or young adult with chronic illness, notably with Chronic fatigue syndrome or ME. It may happen more frequently with a diagnosis of SSD or of chronic childhood illness + SSD.

Where there are disputes between the family and clinicians over an assigned diagnosis or where there is disagreement between clinicians over the etiology of a child’s symptoms, an earlier or concurrent diagnosis of SSD may prejudice the family’s rights and the rights of the child or young person to determine what treatments are administered, where and by whom; or may be used to override or attempt to override the right to consent to treatments, or as a means of limiting parental access to the child and parental involvement in a treatment plan.

A diagnosis of SSD may also impact on a child’s access to suitable educational arrangements, including part-time school attendance, rest periods, reduced curriculum, home tutoring, examination concessions, provision of an amanuensis etc. and access to disability aids and adaptations, or to unhindered use of existing aids, such as wheelchairs.

Again, there is insufficient basis for the approval of SSD for inclusion within ICD-10-CM for application in children or adults. It is scientifically unsafe, premature and against the public interest to include this poorly tested diagnostic construct within ICD.

Thank you for your consideration.

CMS posts ICD-10-CM Release for 2015; confirms Partial Code Freeze extension; reminder, SSD proposals

Post #306 Shortlink: http://wp.me/pKrrB-3SJ

This report updates on the revised implementation date for ICD-10-CM, the revised Partial Code Freeze timeline, the ICD-10-CM Release for 2015 files, and a reminder of the deadline for objections to the insertion of DSM-5’s Somatic symptom disorder into ICD-10-CM.

[For reminder of deadline for objections to proposed insertion of Somatic symptom disorder into ICD-10-CM, skip to red subheading.]

On April 1, 2014, Bill H.R. 4302, known as the PAM Act (Protecting Access to Medicare Act), was signed into law by President Obama.

As a result of a quietly inserted clause piggybacking on this Bill, implementation of ICD-10-CM was delayed by a further year. Centers for Medicare & Medicaid Services (CMS) has confirmed that the effective implementation date for ICD-10-CM is now October 1, 2015.

Until that time, the codes in ICD-10-CM (the U.S. specific adaptation of the WHO’s ICD-10) are not valid for any purpose or use.

+++

Partial Code Freeze

CMS has announced that the partial code freeze on updates to the ICD-9-CM and ICD-10-CM diagnosis and procedure codes will continue until October 1, 2015.

Between October 1, 2011 and October 1, 2016 revisions to ICD-10-CM/PCS will be for new diseases/new technology procedures, and any minor revisions to correct reported errors in these classifications. Regular (at least annual) updates to ICD-10-CM/PCS will resume on October 1, 2016.

The Partial Code Freeze document has been updated to reflect the revised Timeline and can be accessed here in PDF format Partial Code Freeze for ICD-9-CM and ICD-10

or text, below:

Partial Code Freeze for ICD-9-CM and ICD-10

The ICD-10 Coordination and Maintenance Committee (formerly the ICD-9-CM Coordination and Maintenance Committee) implemented a partial freeze of the ICD-9-CM and ICD-10 (ICD-10-CM and ICD-10-PCS) codes prior to the implementation of ICD-10 which would end one year after the implementation of ICD-10. There was considerable support for this partial freeze. On April 1, 2014, the Protecting Access to Medicare Act of 2014 (PAMA) (Pub. L. No. 113-93) was enacted, which said that the Secretary may not adopt ICD-10 prior to October 1, 2015. Accordingly, the U.S. Department of Health and Human Services expects to release an interim final rule in the near future that will include a new compliance date that would require the use of ICD-10 beginning October 1, 2015. The rule will also require HIPAA covered entities to continue to use ICD-9-CM through September 30, 2015. When published, links will be provided to this interim final rule at http://www.cms.gov/Medicare/Coding/ICD10/Statute_Regulations.html

The partial freeze will be implemented as follows:

• The last regular, annual updates to both ICD-9-CM and ICD-10 code sets were made on October 1, 2011.

• On October 1, 2012, October 1, 2013, and October 1, 2014 there will be only limited code updates to both the ICD-9-CM and ICD-10 code sets to capture new technologies and diseases as required by section 503(a) of Pub. L. 108-173.

• On October 1, 2015, there will be only limited code updates to ICD-10 code sets to capture new technologies and diagnoses as required by section 503(a) of Pub. L. 108-173. There will be no updates to ICD-9-CM, as it will no longer be used for reporting.

• On October 1, 2016 (one year after implementation of ICD-10), regular updates to ICD-10 will begin.

The ICD-10 Coordination and Maintenance Committee will continue to meet twice a year during the partial freeze. At these meetings, the public will be asked to comment on whether or not requests for new diagnosis or procedure codes should be created based on the criteria of the need to capture a new technology or disease. Any code requests that do not meet the criteria will be evaluated for implementation within ICD-10 on and after October 1, 2016 once the partial freeze has ended.

CDC has not yet updated its webpages to reflect the ICD-10-CM implementation delay or the revised Partial Code Freeze timeline.

SSD and ICD-10-CM/PCS Coordination and Maintenance Committee proposals

At the September 2013 and March 2014 Coordination and Maintenance Committee meetings, the American Psychiatric Association (APA) submitted numerous requests for addenda changes for new index entries and tabular inclusion terms for evaluation for implementation on October 1, 2015.

It is unclear whether requests for modifications submitted by APA and other requestors via these September and March meetings will be rolled forward for evaluation for implementation on and after the revised date of October 1, 2016 or whether these proposals will now need to be resubmitted at future C & M Committee meetings. (The next public meeting takes place September 23–24, 2014.)

I have approached NCHS for clarification.

+++
If the proposals from these two meetings do require resubmitting, this would provide another opportunity to comment on the proposal to add the DSM-5’s new disorder term, Somatic symptom disorder, to the ICD-10-CM.

See earlier post: Update on proposal to add DSM-5′s Somatic symptom disorder to ICD-10-CM

+++
At the public Coordination and Maintenance Committee meeting on September 18–19, 2013, a proposal had been submitted to add Somatic symptom disorder (SSD) as an inclusion term to existing ICD-10-CM code F45.1 Undifferentiated somatoform disorder in the Tabular List Addendum (this also included addition to the Index).

Note: Proposal is not to create a unique code for SSD or to replace any of the existing ICD-10-CM somatoform disorders with SSD, but to add SSD as an inclusion term under an existing ICD-10-CM code, F45.1.

September 18–19, 2013 meeting Agenda, Page 45: PDF Agenda

ICD10CM 4

+++
The proposal to add somatic symptom disorder to the Index (under Disorder), was resubmitted at the public meeting on March 19–20, (reason unclear but a number of proposals for modifications to both the Tabular List and the Index from the September 2013 meeting were also duplicated at the March 2014 meeting).

March 19–20, 2014 meeting Agenda, Page 89: PDF Agenda

March14 ICD-10-CM Cand M SSD to Index

+++
Any decisions made on the considerable number of proposals requested at last year’s September meeting are yet to be posted and possibly won’t be evident until the relevant Addendum is released.

In the DSM-5, Somatic symptom disorder is already cross-walked to ICD-9 code 300.82 (ICD-10-CM F45.1):

+++
DSM-5 (Page 311)

SSDcrosswalk

+++
Given that APA worked with CDC on the cross-walk between the new DSM-5 disorder terms and ICD-9/ICD-10-CM equivalent codes, NCHS’s Director will likely rubber stamp the APA’s proposals for insertion of SSD and a number of other new DSM-5 categories.

Nevertheless, I shall be putting in another objection before the June 20 deadline and I hope all stakeholders with concerns will strongly oppose the incorporation of this controversial new disorder construct into ICD-10-CM.

The deadline for comments on proposals requested at the March meeting is June 20th.

Send comments, by email, to NCHS to nchsicd9CM@cdc.gov

+++
Not a small thing

Between 2010 and 2012, the SSD Work Group attracted considerable opposition across three stakeholder reviews to its radical proposals for a replacement for the somatoform disorders.

In late 2012 and early 2013, we saw a good deal of “outrage” in comments to articles by Allen Frances and myself here and here at Psychology Today and here in the BMJ, in response to the cavalier decision by the Task Force to barrel through with the SSD Work Group’s poorly validated disorder construct.

But I see little evidence of sustained opposition from U.S. professionals and patients over the September and March NCHS/CMS update and revision meeting proposals to insinuate SSD into ICD-10-CM.

At the moment, the proposal is for inserting SSD as an inclusion term under an existing category – not to create a unique code for SSD and not to replace the existing framework with SSD. At the September meeting, CDC’s Donna Pickett said:

“…And just to complete the package, there are other Tabular List proposals that appear on Page 45 and 46 that we would also invite your comments on. And again, with some of the terminology changes that Dr Regier has described the intent here is to make sure that if those terms are being used, that they do have a home somewhere within ICD-10-CM to facilitate people looking these up. So we invite comments…”

Sounds almost cosy. But if NCHS does rubber stamp the addition of Somatic symptom disorder to ICD-10-CM, it could leverage future replacement of the existing Somatoform disorders categories with this new, single diagnostic construct, bringing ICD-10-CM’s framework in line with DSM-5.

There are implications for ICD-11, too.

Once SSD is inserted into ICD-10-CM, the presence of this term within the U.S. modification of ICD-10 may make it easier for ICD-11 Revision Steering Group to justify approving proposals to replace the existing ICD-10 Somatoform disorders categories with a single, new disorder construct that would mirror SSD’s defining characteristics – its positive psychobehavioural features, its simplified criteria, its de-emphasis on “medically unexplained” and facilitate harmonization between ICD-11 and DSM-5 disorder terms.

Christopher Chute, Mayo, chairs the ICD-11 Revision Steering Group. Chute has suggested that following implementation, ICD-10-CM might be brought gradually in line with ICD-11 through a series of annual updates, for smoother transition to ICD-11-CM.

Inserting the SSD term into ICD-10-CM paves the way for disorder construct congruency between DSM-5, ICD-10-CM, ICD-11, and eventually, the ICD-11-CM modification.

Global creep of DSM-5’s Somatic symptom disorder

Update at April 14, 2014:

Written response (April 10, 2014) from Independent Hospital Pricing Authority (IHPA) to request for clarification regarding the term ‘Somatic symptom disorder’ and Australia’s clinical modification of ICD-10, ICD-10-AM:

PDF: IHPA response re SSD and ICD-10-AM


 

As previously posted:

In the previous posting Update on proposal to add DSM-5′s Somatic symptom disorder to ICD-10-CM I reported that NCHS is preparing to rubber stamp proposals to insert Somatic symptom disorder into the U.S.’s forthcoming clinical modification of ICD-10.

Comments/objections to Diagnosis Agenda proposals submitted at the March meeting need to be sent by email to NCHS at nchsicd9CM@cdc.gov by June 20th.

1] According to this Australian legislative document:

http://www.comlaw.gov.au/Details/F2014L00304

Australian Government, Statement of Principles concerning somatic symptom disorder No. 24 of 2014

for the purposes of the Veterans’ Entitlements Act 1986 and Military Rehabilitation and Compensation Act 2004

“Somatic symptom disorder attracts ICD-10-AM code F45.1.”

For the purposes of the Statement of Principles:

“ICD-10-AM code” means a number assigned to a particular kind of injury or disease in The International Statistical Classification of Diseases and Related Health Problems, 10th Revision, Australian Modification (ICD-10-AM), Eighth Edition, effective date of 1 July 2013, copyrighted by the Independent Hospital Pricing Authority, and having ISBN 978-1-74128-213-9;”

The Australian ICD-10-CM, Eighth Edition, July 2013 is not in the public domain. As I do not have access to a copy, I have contacted the relevant body for clarifications.

I have asked whether Somatic symptom disorder has been added to the Eighth Edition of ICD-10-AM as an Inclusion term to F45.1 Undifferentiated somatoform disorder in the Tabular List and Alphabetical Index.

Or, whether this legislative document relies on the ICD cross-walk codes as published in the DSM-5 in May 2013 for the cross-walk between DSM-5 disorders and the disorders in the U.S.’s ICD-9-CM and forthcoming ICD-10-CM.

Or, whether the legislative document relies on a cross-walk between DSM-5 disorders and ICD-10-AM codes developed specifically in relation to the ICD-10-AM Eighth Edition, July 2013.

I will update this post when I have received clarification.

According to this page: http://nccc.uow.edu.au/icd10am-achi-acs/overview/icd10am/index.html

“[Australia’s] ICD-10-AM has also enjoyed more widespread use, having been assessed, found suitable and adopted by many other countries, including: New Zealand, Ireland, Singapore, Slovenia.”

I am unable to confirm how many countries that have adopted ICD-10-AM have migrated from earlier editions to the July 2013 edition or are preparing to migrate to the most recent edition.

Other clinical modifications (CMs) of ICD-10:

Canada (ICD-10-CA): The most recent edition of ICD-10-CA is the 2009 edition Volume One: Tabular List 2009. Canada is anticipated to adopt a CM of ICD-11 before the U.S. does, but in meantime, an updated edition of ICD-10-CA might be anticipated, especially given the recent extension to the ICD-11 development timeline. Canadians will need to be alert to the potential for addition of SSD as an inclusion term to the next edition of ICD-10-CA.

Germany (ICD-10-GM): There is an ICD-10-GM version for 2014. There is no SSD under F45.x or under any other code, but watch for any updated versions released prior to transition to a CM of ICD-11.

Thailand (ICD-10-TM): There does not appear to be a more recent version of the Thai clinical modification than the online version for 2007, but watch for SSD in any updated versions prior to potential transition to a CM of ICD-11. ICD-10-TM Online version for 2007.

ICD-11 Beta drafting platform:

There is no documentary evidence of a proposal to add SSD, per se, to ICD-11. However, the wording for the Definition for Bodily distress disorder, as it currently stands in the Beta drafting platform, is drawn from the Gureje, Creed 2012 paper on the S3DWG sub working group’s emerging proposals for ICD-11 [1].

The paper described a simplified disorder framework – a construct into which DSM-5′s Somatic Symptom Disorder could be comfortably integrated, thus facilitating harmonization between the respective ICD-11 and DSM-5 disorder construct and criteria replacements for the Somatoform disorders classifications.

As with DSM-5′s SSD, for the emerging proposals for BDD, the focus was not on symptoms counts, or on strict symptom patterns or clusters from one or more body systems, or on whether symptoms were determined as being “medically explained” or “medically unexplained,” but on the perception of disproportionate or maladaptive psychobehavioural responses to, or excessive preoccupation with any troublesome chronic bodily symptom(s). And that in doing away with the “unreliable assumption of its causality” the diagnosis of BDD would not exclude the presence of a co-occurring physical health condition – which is very close to SSD’s defining characteristics.

2] On the Patient.co.uk site, a peer reviewed article on Somatic symptom disorder:

http://www.patient.co.uk/doctor/somatic-symptom-disorder

This article is not a recommendation and it draws heavily on the DSM-IV and current ICD-10 Somatoform disorders framework, criteria and literature. Though it does highlight that DSM-5 has a new, simplified framework and reformulated criteria that rely less on strict patterns of somatic symptoms and more on the degree to which a patient’s thoughts, feelings and behaviours about their symptoms are considered disproportionate or excessive; that for DSM-5, “medically unexplained” is de-emphasized – symptoms may or may not be associated with another medical condition and patients with organic comorbidities such as heart disease, osteoarthritis or cancer, who would have previously been excluded under DSM-IV, can now be included in the diagnosis of SSD.

There is little published research examining the reliability, utility, epidemiology, clinical characteristics or treatment of Somatic symptom disorder as a diagnostic construct and none of the article’s references are for papers specifically using the new Somatic symptom disorder criteria.

Dr Max Henderson, senior lecturer in Epidemiology and Occupational psychiatry, Inststitute of psychiatry, Kings College London 

According to the authors, fibromyalgia ( coded in ICD-10 under Chapter XXIII Diseases of the musculoskeletal system and connective tissue, at M79.7 ) is more appropriately described in terms of “polysymptomatic distress”; “polysymptomatic distress has been recognised as a somatoform disorder, specifically as a somatic symptom disorder or SSD,” and that since “FM overlaps with other disorders with medically unexplained symptoms such as irritable bowel syndrome and chronic fatigue syndrome” it is more appropriate to treat them with multidisciplinary teams within the same specialised service in the general hospital.
