Wrong again
The code under the WHO expressely states that any illness can not be listed in terms of both a phsysical and psychological causual agent.
1) CFS is an umbrella term that includes mental illness. (E.g. OXFORD CFS Criteria). Used by Wessely/Sharpe/White/Chalder/ etc
2) CFS/ME is a dual coding description of two disease states (not allowed to dual code under the WHO), however it exists only in the UK.
There is no such thing as CFS/ME or ME/CFS as a disease state - precisely due to the dual coding issue that is prohibited.
Although I do understand CFS has a different meaning in the US.
I thought it might be useful to have an actual quote from WHO, Geneva,
...according to the taxonomic principles governing the Tenth Revision of the World Health Organization's International Statistical Classification of Diseases and Related Health Problems (ICD-10) it is not permitted for the same condition to be classified to more than one rubric as this would mean that the individual categories and subcategories were no longer mutually exclusive. The same principles will apply to ICD-11. Dr Robert Jakob, WHO Classifications, Terminology and Standards Team, Geneva
(Note the following applies to ICD-10 and not the codings currently proposed for the US Clinical Modification ICD-10-CM due for implementation in October 2013, which are different)
Currently, in ICD-10:
Benign myalgic encephalomyelitis is classified in
Volume 1: The Tabular List in Chapter VI at G93.3 (and in
Volume 3: The Alphabetical Index at G93.3)
http://www.who.int/classifications/apps/icd/icd10online/?gg90.htm+g933
CHAPTER VI (CHAPTER 6)
Diseases of the nervous system (G00-G99)
Other disorders of the nervous system (G90-99)
Other disorders of brain
G93.3 Postviral fatigue syndrome
Benign myalgic encephalomyelitis
(Note NOT "
infectious diseases" but
Other disorders of the nervous system >
Other disorders of brain)
In ICD-10 (
Note NOT the codings proposed for the US Clinical Modification ICD-10-CM due for implementation in October 2013, which are different) :
Chronic fatigue syndrome (note NOT "CFS" or "CFS/ME" or "ME/CFS" because WHO does not use these dual terms in its classificatory system)
is not included in
Volume 1: The Tabular List.
It is currently indexed only in
Volume 3: The Alphabetical Index.
It is indexed at
G93.3 (the same code as for PVFS and Benign ME)
You can see it here:

WHO HQ does not include definitions in ICD-10 for PVFS, ME or "Chronic fatigue syndrome". It is not known how it views the relationship between these three terms. This may or may not be clarified in ICD-11.
It is not yet known whether the WHO Topic Advisory Group for Neurology intends to propose that "Chronic fatigue syndrome" should be included in Chapter VI of Volume 1: The Tabular List in ICD-11. But since all volumes of ICD-11 will integrate with each other it seems unlikely to me that they would leave Chronic fatigue syndrome indexed in Volume 3 at G93.3 but not mapped across to Volume 2.
If Chronic fatigue syndrome
were to be classified in Chapter VI at G93.3 in Volume 2, then it cannot also be classified in any other chapter - which includes Chapter V (Mental and Behavioural Disorders).
This has relevance for DSM-V and the "harmonization of ICD-11 Chapter V and DSM-V" issue.
Again, I am talking ICD-10 and ICD-11 NOT the US ICD-10-CM Clinical Modification.
So with reference to DSM-V, it is incorrect to say that
So instead of going from the Infectious Disease category, CFS is going from "somatoform disorder" to "somatic symptoms disorder"?
Because:
a) ME is NOT classified within DSM.
Chronic fatigue syndrome is NOT classified within DSM.
b) Neither ME or Chronic fatigue syndrome are classified in either ICD-10 or DSM under "
Infectious Disease category"
c) DSM has NOT proposed that Chronic fatigue syndrome "...is going from "somatoform disorder" to "somatic symptoms disorder?"
d) DSM has NOT proposed classifying and coding specifically for Chronic fatigue syndrome or ME or FM or IBS.
What DSM has proposed so far (and this may have changed by the time the draft comes out) is the following:
To get rid of the term "medically unexplained" in order to
"...diminish the “dichotomy, inherent in the ‘Somatoform’ section of DSM-IV, between disorders based on medically unexplained symptoms and patients with organic disease.”
To rename the "Somatoform Disorders" category (possibly)
“somatic symptom disorder”
To propose a framework that:
“…will allow a diagnosis of somatic symptom disorder in addition to a general medical condition, whether the latter is a well-recognized organic disease or a functional somatic syndrome such as irritable bowel syndrome or chronic fatigue syndrome.”
For example, by placing "general medical conditions" and the so-called "functional somatic syndromes (FSSs)" on one Axis BUT WITH THE ABILITY TO ALLOW AN ADDITIONAL DIAGNOSIS of "somatic symptom disorder" (or whatever they are thinking of calling it) to ALL disorders/diseases/conditions.
DSM SDD Work Group members (and many within the psychiatric profession) already refer to
CFS, FM, IBS, MCS, CI, CS and a number of others
under the umbrella term "functional somatic syndromes (FSSs)" - this is nothing new.
This proposal would have implications for all diseases/disorders but it is not the same as saying that DSM wants to classify CFS
under "somatoform disorders" or "somatic symptoms disorder" or whatever.
Think of it like this:
Heart disease + the potential for an additional Dx of "somatic symptom disorder"
Diabetes + the potential for an additional Dx of "somatic symptom disorder"
MS + the potential for an additional Dx of "somatic symptom disorder"
CFS + the potential for an additional Dx of "somatic symptom disorder"
FM + the potential for an additional Dx of "somatic symptom disorder"
