Dear Ms Curtin and Professor Miles,
Re: Journal of Evaluation in Clinical Practice, Version of Record online: 01 August 2019: Original Paper: White PD. A perspective on causation of the chronic fatigue syndrome by considering its nosology [1].
I write to bring to your attention errors within Professor White's paper, specifically in relation to classification and coding in ICD-10 and ICD-11.
I am taking the liberty of copying in three key members of the World Health Organization's ICD-11 development team, Drs Jakob, Reed and Chute, whom you may wish to consult.
1: The author states:
'Turning to established diagnostic classification systems, how are CFS and ME considered? There are arguably seven different ways to classify the illness within the International Classification of Diseases, 10th edition (ICD‐10).24 . . . Finally, the miscellaneous chapter includes “R53.82 Chronic fatigue, unspecified,” which includes “chronic fatigue syndrome NOS,” and if a patient is of a certain age, one might even consider “R54 Senile asthenia”!'
24. World Health Organisation. International Classification of Diseases, 10th edition. 2016. Retrieved from: https://www.who.int/classifications/icd/icdonlineversions/en/
This statement is incorrect.
There is no code "R53.82 Chronic fatigue, unspecified" or inclusion, "chronic fatigue syndrome NOS" within the International Classification of Diseases, 10th edition. 2016.
"R53.82 Chronic fatigue, unspecified" and its inclusion, "chronic fatigue syndrome NOS" are specific to the U.S.'s clinical modification, ICD-10-CM, which is developed and maintained by NCHS/CDC [2].
These two terms were added by NCHS to ICD-10-CM's Chapter 18: Symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R99) during the ICD-10-CM development and adaptation process. Neither term is coded for or indexed within the WHO's ICD-10 (which has no Tabular List four or five character codes between R53 and R54), or within ICD-11.
2: The author states:
'The 11th edition of the ICD still holds ME in the neurology chapter, classified under post‐viral fatigue syndrome, whereas there has been a radical change to somatoform disorders within the mental and behavioural disorders chapter, which now considers these as examples of “body [sic] distress disorder.” Neurasthenia has been omitted.2'
which is correct, but the author goes on to state:
'This clustering of functional somatic syndromes has been reported many times and needs to be considered in any study of the aetiology of CFS. Fink's concept of body [sic] distress syndrome recently incorporated into ICD‐11 is an alternative way of considering this finding.29'
29. Fink P, Schröder A. One single diagnosis, bodily distress syndrome, succeeded to capture 10 diagnostic categories of functional somatic syndromes and somatoform disorders. J Psychosom Res. 2010;68(5): 415‐426.
This statement is incorrect.
The Fink P, Schröder A. (2010) diagnostic construct, "Bodily distress syndrome (BDS)" has not been incorporated into ICD-11 MMS (Mortality and Morbidity Statistics).
For the core ICD-11, WHO has approved the differently conceptualized, "Bodily distress disorder (BDD)" with three coded for severity specifiers [3][4].
Creed & Gurege [5], Gurege & Reed [6] and Per Fink [7] clarify that as defined for ICD-11, BDD is a conceptually different diagnosis: ICD-11's BDD and the Fink P, Schröder A. (2010) BDS are differently characterized, have very different disorder descriptions/criteria, and are inclusive of different patient sets.
Rather than provide clarity around ICD classification, misconceptions within this paper will add further confusion between these divergent diagnostic constructs.
I should be pleased if these errors can be discussed with the paper's author and with the WHO and addressed either in the version of the paper currently online or via corrigenda.
Sincerely,
Susan E Chapman
