The two key Somatic Symptoms Disorders Work Group Draft Proposal documents:

  Descriptions document version 1/14/11  Revised Disorder Descriptions: Version 1/14/11

    Revised Justification of Criteria Version 1/31/11

On 16 January, I reported on my Dx RevisionWatch site that the page for current DSM-5 proposals for the revision of the DSM-IV categories and diagnostic criteria for “Somatoform Disorders” had been updated on 14 January, with a new category proposal calledSimple Somatic Symptom Disorder”.

This proposal is in addition to the recommendations of the Somatic Symptom Disorders Work Group, published in February 2010, for grouping a number of existing Somatoform categories under a common rubric “Complex Somatic Symptom Disorder (CSSD)” and does not replace “CSSD”.

For full details see Dx Revision Watch Post #56: http://wp.me/pKrrB-St

[Information superceded by second and third DSM-5 draft.]

Update @ 7 February 2011

The Justification of Criteria document has now been revised by the SSD Work Group to incorporate the new proposal for SSSD and some further revisions, and is replaced by a document designated DRAFT 1/31/11.

I shall be monitoring the DSM-5 Development website and if there are any further revisions to either document before the DSM-5 beta is published I will update this site.

Two key Somatic Symptoms Disorders Work Group Draft Proposal documents:

    Revised Justification of Criteria Version 1/31/11

  Descriptions document version 1/14/11 Revised Disorder Descriptions: Version 1/14/11

According to the APA’s DSM-5 Development Timeline, beta draft proposals are scheduled to be published by the DSM-5 Task Force in May-June, with a public review period of only around a month. The public review and comment period for the first draft, last year, had been around ten weeks.

US “Clinical Modification” ICD-10-CM: Clarification

US “Clinical Modification” ICD-10-CM: Clarification

Shortlink: http://wp.me/p5foE-2Ul

This post is intended to clarify any confusion between ICD-10, ICD-11 and the forthcoming US Clinical Modification of ICD-10 which will be known as ICD-10-CM.

The WHO published ICD-10 in 1992. The current version of ICD-10 (Version for 2007) is used in the UK and in many countries throughout the world.

ICD-10 is under revision and the development of the structure and content of ICD-11 has been underway since 2007. ICD-11 is scheduled for completion in 2014.

 

Clinical Modifications

Several countries are permitted to publish adaptations of the ICD called “Clinical Modifications” (sometimes known as “national modifications”).

Countries using Clinical Modifications of ICD-10 include Canada (ICD-10-CA), Australia (ICD-10-AM) and Germany (ICD-10-GM).

The United States currently uses an adaptation of the WHO’s now retired ICD-9, called ICD-9-CM, and has been slow to move onto ICD-10.

Rather than skip ICD-10 and move straight onto ICD-11 in 2014+, the US has been developing a modification of ICD 10 called ICD-10-CM which will replace ICD-9-CM.

ICD-10-CM is due for implementation in October 2013.

According to one report, the US should not expect to move on to ICD-11 (or a modification of ICD-11) until well after 2020, assuming that the ICD-11 Beta is published around the 2014-2015 projection:

Why move to ICD-10, if ICD-11 is on the horizon?
http://www.healthcarefinancenews.com/news/why-move-icd-10-if-icd-11-horizon

 

What are the proposed classifications and codings for PVFS, (Benign) ME and Chronic fatigue syndrome for ICD-10-CM?

In March 2001, the document:

“A Summary of Chronic Fatigue Syndrome and Its Classification in the International Classification of Diseases Prepared by the Centers for Disease Control and Prevention, National Center for Health Statistics, Office of the Center Director, Data Policy and Standards”

provided a concise “summary of the classification of Chronic Fatigue Syndrome in the International Classification of Diseases (ICD), ninth and tenth revisions, and their clinical modifications.”

That document is archived here: http://www.co-cure.org/ICD_code.pdf

In 2001, the proposal had been:

“In keeping with the placement in the ICD-10, chronic fatigue syndrome (and its synonymous terms) will remain at G93.3 in ICD-10-CM.”

So at that point, it was being proposed for the forthcoming US ICD-10-CM that PVFS, (Benign) ME and Chronic fatigue syndrome would be coded at G93.3, which would have placed all three terms in Chapter VI: Diseases of the nervous system (the Neurological chapter).

But the current proposals for ICD-10-CM propose classifying Chronic fatigue syndrome in Chapter 18, under R53 Malaise and fatigue, at R53.82.

The “R” codes are classified under

CHAPTER 18 (XVIII)
Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R99)

This chapter includes symptoms, signs, abnormal results of clinical or other investigative procedures, and ill defined conditions regarding which no diagnosis classifiable elsewhere is recorded…

Note: this is not the ICD-10-CM Mental and Behavioural chapter, which is:

CHAPTER 5 (V)
Mental and behavioral disorders (F01-F99)
Includes: disorders of psychological development
Excludes2: symptoms, signs and abnormal clinical laboratory findings, not elsewhere classified (R00-R99)

which specifically excludes the R00-R99 codes.

So the current proposal for ICD-10-CM separates CFS and Postviral fatigue syndrome into mutually exclusive categories:

“Chronic fatigue, unspecified” and “Chronic fatigue syndrome not otherwise specified” appear in Chapter 18, under R53 Malaise and fatigue, at R53.82.

Whilst “Postviral fatigue syndrome” and “benign myalgic encephalomyelitis” appear in Chapter 6, under G93 Other disorders of brain, at G93.3.

At some point before October 2013, ICD-10-CM revision will be “frozen” for Centers for Medicare and Medicaid Services (CMS) and insurance companies to prepare for the October 1, 2013 implementation.

See Tom Sullivan at ICD10 Watch.com (no connection with my site) here:

CMS, CDC call for ICD-9 and ICD-10 code freeze
http://icd10watch.com/headline/cms-cdc-call-icd-9-and-icd-10-code-freeze

“CMS, the Centers for Medicare and Medicaid Services, along with CDC, the Centers for Disease Control and Prevention, proposed that both ICD-9-CM and ICD-10-CM/PCS code sets be frozen two years before the compliance deadline.

“What that means: As of October 1, 2011, only limited updates would be instituted into the code sets so that providers, payers, clearinghouses, and health IT vendors, will not have to simultaneously keep pace with code updates while also reconfiguring their existing systems for ICD-10-CM/PCS.” ICD10 Watch.com

During the last ten minutes of the CFSAC meeting on Monday, 10 May, Dr Lenny Jason raised his concerns with the committee that the placement of CFS in ICD-10-CM in the Chapter 18 “R” codes could be problematic.

Videocast of full CFSAC meeting here:
http://videocast.nih.gov/Summary.asp?File=15884

In August 2005, CFSAC had submitted the following recommendation to the Secretary:

http://www.hhs.gov/advcomcfs/recommendations/082005.html

“Recommendation 10: We would encourage the classification of CFS as a ‘Nervous System Disease,’ as worded in the ICD-10 G93.3.”

I suggest that US advocates with concerns about current proposals for the placement of CFS within ICD-10-CM keep a close eye on decisions about the date by which ICD-10-CM is to be frozen.

For information on the current codings in ICD-9-CM (US Clinical Modification) see the NAME U.S. page: WHO ICD Codes section

American Psychiatric Association on DSM-5

In a 10 December Press Release, the American Psychiatric Association said:

“Extending the timeline [for DSM-5] will allow more time for public review, field trials and revisions”

and

“The extension will also permit the DSM-5 to better link with the U.S. implementation of the ICD-10-CM codes for all Medicare/Medicaid claims reporting, scheduled for October 1, 2013. Although ICD-10 was published by the WHO in 1990, the “Clinical Modification” version (ICD- 10-CM) authorized by the U.S. Centers for Medicare and Medicaid Services (CMS) and the Centers for Disease Control (CDC) is not being implemented in the U.S. until 23 years later.

“The ICD-10-CM includes disorder names, logical groupings of disorders and code numbers but not explicit diagnostic criteria. The APA has already worked with CMS and CDC to develop a common structure for the currently in-use DSM-IV and the mental disorders section of the ICD- 10-CM.

“The International Classification of Diseases (ICD) is published by the WHO for all member countries to classify diseases and medical conditions for international health care, public health, and statistical use. The WHO plans to release its next version of the ICD, the ICD-11, in 2014.

“APA will continue to work with the WHO to harmonize the DSM-5 with the mental and behavioral disorders section of the ICD-11. Given the timing of the release of both DSM-5 and ICD-11 in relation to the ICD-10-CM, the APA will also work with the CDC and CMS to propose a structure for the U.S. ICD-10 CM that is reflective of the DSM-5 and ICD-11 harmonization efforts. This will be done prior to the time when the ICD-10-CM revisions are “frozen” for CMS and insurance companies to prepare for the October 1, 2013, adoption.”

The information in this report relates to proposals for ICD-11. It does not apply to ICD-10-CM, the forthcoming US “Clinical Modification” of ICD-10.

 

Whither the ICD-11 Alpha Draft?

According to documents published by the ICD Revision Steering Group (RSG) and the Agenda for the iCAMP2 and Revision Steering Group meeting on 19-23 April 2010, it was projected that an alpha draft for ICD-11 would be ready by 10 May 2010 [Key document 1a].

The RSG meeting Agenda proposed that the alpha draft should be presented to the World Health Assembly (WHA) between 17-25 May. A proposal for a press launch was also tabled for discussion.

It is understood that the ICD-11 alpha draft is being created for internal users, was not expected to be complete by May 2010, but released as a “work in progress” towards the beta stage. The beta draft for ICD-11 is scheduled for 2011, which will be subjected to systematic field trials and then made available for public comment.

10 May has come and gone, and there has been no public launch of an alpha draft or the iCAT – the wiki-like collaborative authoring platform through which ICD-11 is being drafted.

As the Minutes of the April RSG meeting are not yet available, it remains unclear how on target the alpha draft is or whether the goals for 2010 have had to be revised. (See Page 7, ICD-11 Revision Project Plan – Draft 2.0 for Project milestones and budget, and organizational overview.)

When the RSG does release information on the status of the alpha draft and the operational status of the iCAT, I will post an update.

In the meantime, I have raised a number of queries around the status of the alpha draft, whether the RSG intends to make a draft available for public viewing, at what point, and in what format(s). I have also asked for information about the availability of Topic Advisory Group proposal forms for stakeholder input, up to what stage in the development process timeline these might be used, and which stakeholders are going to be permitted to make use of proposal forms.

 

iCAT production server

In the posting ICD-11 Alpha Draft scheduled to launch between 10 and 17 May, 6 May, I reported that it is already possible to view a “Demo and Training iCAT Platform” and also access the iCAT production server.

I cautioned that until an official ICD-11 Alpha Draft is released, it cannot be determined how far the various Topic Advisory Groups have progressed with revising classifications and populating textual content according to a common “Content Model” for the ICD Chapters and categories of interest to us [Key document 1b].

I noted that the Demo and Training iCAT Platform, at that point, was sparsely populated for content and that the classifications and codings listed within the various chapters appeared to have been imported from ICD-10, with little discernable change – presumably as the starting point for the drafting process.

A revised Demo and Training iCAT Platform is now accessible, the content of which is also viewable on the iCAT production server and it is to these proposed revisions that I want to draw your attention.

Note that anyone can view the Demo and Training iCAT Platform and iCAT production server but only WHO, ICD Revision and IT personnel and the Managers and members of the various Topic Advisory Groups (TAGS)will have editorial access. External reviewers recruited by TAG Managers will also use the iCAT to upload reviews and comment on proposals and content.

I have compiled a series of screenshots and very brief notes on what is viewable at the moment for the chapters and categories of interest to us.

Note: Screenshots are taken from the Demo and Training iCAT Platform and iCAT production server as they stood at 24 May 2010. Alpha drafting is an ongoing process and what currently appears may be subject to revision, refinement and additions before an official Alpha Draft is released. Not all the classification and content work currently undertaken may have been entered into the iCAT.

Note also that when viewing the iCAT in your browser, the left hand side of the screen displays the ICD Categories listings with the category Definition, Term, Clinical Description, Diagnostic Criteria etc displaying on the right of the screen. Because this view is too wide to display on my website template, the screenshots have had to be split in two. On your screen the iCAT will look like this:

 

When you have read this report and familiarised yourself with the way the iCAT functions, I suggest you poke around – you can’t break anything as members of the public have no editing access.

All screenshots as they stood at 24 May 2010

A wiki-like Collaborative Authoring Tool (known as the iCAT)) is being used for the initial authoring of the alpha draft.

The iCAT production server and Demo and Training iCAT Platform can be accessed here:

https://sites.google.com/site/icd11revision/home/icat

iCAT production server at: http://icat.stanford.edu/

Demo and Training iCAT Platform at: http://icatdemo.stanford.edu/

Load either (they may take a minute or more to load and appear less inclined to hang in Firefox).

One loaded, you will be presented with an Entry Page – this is the My ICD Tab

Welcome to iCAT – the Initial ICD 11 Collaborative Authoring Tool!

Select the ICD Content Tab and ICD Categories by chapter will populate down the left side of the screen.

Scroll down and open up the + next to 06 VI Diseases of the nervous system

ICD Categories:

 

Scroll down and note that ICD-10 codings between G83.9 and G99.8 are being reorganised and have been assigned the labels GA thru GN (some of which, like GN, are parent categories with child and grandchildren categories).

Open up the + next to GN Other disorders of the nervous system

which is a parent to category Gj92 Chronic fatigue syndrome

(Note: Gj92 is known as a “Sorting label”. A Sorting label is a string that can be used to sort the children of a category. This is not the ICD code.)

Note that Postviral fatigue syndrome and Benign myalgic encephalomyelitis are not currently accounted for in the ICD Categories List as children of the parent category GN Other disorders of the nervous system. Only Chronic fatigue syndrome is listed and assigned the Sorting Label “Gj92”. [See Glossary: Inclusions]

 

 

Click on the double speech bubble icon next to Gj92 Chronic fatigue syndrome which will display 1 Category Discussion Note (Click Expand to display the full note. Discussion Notes can also be accessed via the Category Notes and Discussions Tab, from which the screenshot below, orginates).

Discussion Note for Gj92 Chronic fatigue syndrome:

This Discussion Note records a Change in hierarchy for class: G93.3 Postviral fatigue syndrome because its parent category (G93 Other disorders of brain) is removed.

Note that the removal of the parent G93 Other disorders of brain will affect other categories also classified under G93 in ICD-10, not just G93.3. Open up the double speech bubble icons next to other category listings and you can view the Discussion Notes on proposed restructuring for other G8x and G9x categories.

Next, with the ICD Content Tab selected, click on Gj92 Chronic fatigue syndrome and the Details for Gj92 Chronic fatigue syndrome will display on the right side of the screen. Allow a few moments for the text in the boxes to load.

With the Title & Definition Tab selected (the Tab may read Definition only, depending on whether you are viewing the iCAT production server or the Demo iCAT), you can view the

Details for Gj92 Chronic fatigue syndrome

To view a Glossary of Terms page, which defines the terms in the Tabs click on the blue question mark icons which will load the iCAT Glossary.

Content for Gj92 Chronic fatigue syndrome:

[See Glossary: Definition] The full text of External Definitions (imported from affiliate classification publications) which is partly hidden in the screenshot, is appended at end of this post. According to discussion on the iCAT Users Google Group, it is proposed that External Definitions might be given less prominence when displaying in the iCAT.

 

Now click on the Terms Tab.

Terms for Gj92 Chronic fatigue syndrome:

Benign myalagic encephalomyelitis currently appears listed under Inclusions to Gj92 Chronic fatigue syndrome.

Note that Postviral fatigue syndrome is not listed under Inclusions and that Synonyms and Exclusions for Gj92 Chronic fatigue syndrome have yet to be populated. [See Glossary: Synonyms, Inclusions, Exclusions]

Very few of the other Content Tabs have been populated but it is envisaged that they will be in due course.

I provide no screenshots for Benign myalagic encephalomyelitis or Postviral fatigue syndrome because these are not listed in the ICD Categories List. [See Glossary: ICD Title, Synonyms, Inclusions, Exclusions]

Extract from the iCAT Glossary

6. Inclusions

Short definition: Inclusion terms are either synonyms of the category titles or subclasses which are not represented in the classification hierarchy.

Details: Inclusion terms appear in the tabular list of the traditional print version and show users that entities are included in the relevant concept. All of the ICD-10 inclusion terms have been imported and accessible in the iCat. These are either synonyms of the category titles or subclasses which are not represented in the classification hierarchy. Since we have synonyms as a separate entity in our ICD-11 content model, the new synonyms suggested by the users should go into the synonyms section. In the future, iCat will provide a mechanism to identify whether an inclusion is a synonym or a subclass.

7. Exclusions

Short definition: Exclusion terms help users eliminate entities that should be assigned to a different ICD category because of differences in meaning or terminology.

External Definitions: (Imported from affiliate classification publications, these remain the same as my 6 May posting.)

External Definitions for Gj92 Chronic fatigue syndrome

A syndrome of unknown etiology. Chronic fatigue syndrome (CFS) is a clinical diagnosis characterized by an unexplained persistent or relapsing chronic fatigue that is of at least six months duration, is not the result of ongoing exertion, is not substantially alleviated by rest, and results in substantial reduction of previous levels of occupational, educational, social or personal activities. Common concurrent symptoms of at least six months duration include impairment of memory or concentration, diffuse pain, sore throat, tender lymph nodes,headaches of a new type, pattern, or severity, and nonrestorative sleep. The etiology of CFS may be viral or immunologic. Neurasthenia and fibromyalgia may represent related disorders. Also known as myalgic encephalomyeltis.

Ontology ID UMLS/NC12007_05
E

distinctive syndrome characterized by chronic fatigue, mild fever, lymphadenopathy, headache, myalgia, arthralgia, depression, and memory loss: candidate eitiological agents include Epstein-Barr and other herpesviruses.

Ontology ID UMLS/CSP2006

A syndrome characterized by persistent or recurrent fatigue, diffuse musculoskeletal pain, sleep disturbances, and subjective cognitive impairment of 6 months duration or longer. Symptoms are not caused by ongoing exertion; are not relieved by rest; and result in a substantial reduction of previous levels of occupational, educational, social or personal activities. Minor alterations of immune, neuroendocrine, and automatic function may be associated with this syndrome. There is also considerable overlap between this condition and FIBROMYALGIA.

Based only on the information visible in the iCAT as it stood at 24 May 2010, it appears that instead of:

that what may be being proposed at this point is:

that G83.9-G99.8 codes in ICD-10 Chapter VI: Diseases of the nervous system are being restuctured;

that G93 Other disorders of brain is removed as a parent category for G93.x codings;

that GN Other disorders of the nervous system is the parent to

that Gj92 Chronic fatigue syndrome is included in ICD-11 Chapter 06 VI Diseases of the nervous system (Neurology chapter) in the ICD Categories list as an ICD Title term;

that there is currently displaying no Gj9x Sorting label (or any other Sorting label) listing for Postviral fatigue syndrome or Benign myalgic encephalomyelitis in ICD Categories list or any Category Details for either term;

(Whether this is because Inclusion terms appear in the tabular list of the traditional print version but not in the iCAT version, or because of proposed hierarchy changes to the relationship between these three terms or because text remains to be entered into the iCAT for these two terms, cannot be determined from the information available at 10 June – please refer to Glossary of Terms which sets out the relationships between an ICD Title and its inclusion in the iCAT Categories list and between an ICD Title and its Synonyms, Inclusions and Exclusions.)

that Gj92 Chronic fatigue syndrome is an ICD Title term with a Details page, a Definition and an Inclusion term (but with no Synonyms or Exclusions or other fields yet populated);

that Benign myalgic encephalomyelitis is listed as an Inclusion to Gj92 Chronic fatigue syndrome

that Chapter 5 V Details for F48.0 Neurasthenia specifies
“postviral fatigue syndrome” as an Exclusion with References

G93.3 -> Gj92 Chronic fatigue syndrome

that Chapter 18 XVIII Details for R53 Malaise and Fatigue specifies
“fatigue syndrome postviral” [sic] as an Exclusion with References

F48.0 -> F48.0 Neurasthenia,
G93.3 -> Gj92 Chronic fatigue syndrome

but that in the absence of further information, it is currently unclear what the proposed hierarchical status of Postviral fatigue syndrome and Benign myalgic encephalomyelitis will be in relation to Chronic fatigue syndrome, and in relation to each other.

I shall continue to monitor the iCAT production server closely and report on any changes to proposals for Category listings and on the progress of the population of content.
