ME :: Myalgic Encephalomyelitis

CFS :: Chronic Fatigue Syndrome

WHO :: World Health Organisation

The following are extracts from the World Health Organisation ICD-10 or US ICD-10 CM July 2007 (draft since 2003), it should be noted that postviral fatigue syndrome and benign myalgic encephalomyeliyis (chronic fatigue syndrome, postviral is listed only in the 2003 draft) are listed under the code G93.3 with the following exclusion,(NOT CODED HERE) chronic fatigue syndrome NOS (R53.82). Thus CFS is listed once 1 : 'Chronic Fatigue Syndrome NOS' (R53.82). Note that R53.82 excludes postviral fatigue syndrome (G93.3). Neither listing make any referrence to F48.

Another item of some interest is the listing for Neurasthenia, where WHO ICD-10 codes under F48.0 and the US ICD-10 CM codes neurasthenia under F48.8, the WHO excludes postviral fatigue syndrome and the US lists no exclusions.

The extracts below are all the entries for ME and CFS that I could locate within the US ICD-10 CM (tabular)
