Hi
@Dx Revision Watch - can you include the exclusions for the ICD10 G.93.3.
It drives me nuts when even some patients call ME 'Chronic Fatigue'
WHO's ICD-10:
The Title term: G93.3 Postviral fatigue syndrome (which includes the inclusion term: Myalgic encephalomyelitis and the G93.3 index term, Chronic fatigue syndrome) is specified as an exclusion under
F48.0 Neurasthenia and its inclusion term,
Fatigue syndrome:
G93.3 is also specified as an exclusion under the Symptoms, signs chapter
R53 Malaise and fatigue:
There is no term, "Chronic fatigue" as such within ICD-10 - only "Fatigue syndrome" (F48.0) in the Tabular List and "Chronic fatigue syndrome" (G93.3) in the Index.
In ICD-10, there are no reciprocal exclusions for F48.0 and R53 under G93.3 Postviral fatigue syndrome.
However, for ICD-11, there is an exclusion for Fatigue
(MG22)* under 8E49 Postviral fatigue syndrome and under 6C20 Bodily distress disorder (which replaces and subsumes the retired ICD-10 term, Neurasthenia), all three terms: Postviral fatigue syndrome
(8E49); Chronic fatigue syndrome
(8E49); Myalgic encephalomyelitis
(8E49) are specified as exclusions to Bodily distress disorder.
*ICD-10 Title term "Malaise and fatigue" has been replaced by "Fatigue" for ICD-11.
There is this cautionary note for clinicians and coders in the National Clinical Coding Standards ICD-10 5th Edition (2024):
Edit: Note there remains a code for "Chronic fatigue, unspecified" in the US's ICD-10-CM at R53.82 which has an Excludes1 for the following:
chronic fatigue syndrome (G93.32)
myalgic encephalomyelitis (G93.32)
other post infection and related fatigue syndromes (G93.39)
postviral fatigue syndrome (G93.31)
with a reciprocal Excludes 1 for "chronic fatigue NOS (R53.82)" under G93.3 Postviral and related fatigue syndromes.
