Postviral fatigue syndrome
distinctive syndrome characterized by chronic fatigue, mild fever, lymphadenopathy, headache, myalgia, arthralgia, depression, and memory loss; candidate etiologic agents include Epstein-Barr and other herpesviruses.
Syndrome thought to be caused by a viral organism resulting in chronic fatigue, fever, pain, sore throat, and, in some cases, depression.
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 encephalomyelitis.
G93.3 is a specific ICD-10-CM diagnosis code that can be used to specify a diagnosis.
ICD-9-CM will be replaced by ICD-10-CM beginning October 1, 2013, therefore, G93.3 and all other ICD-10-CM diagnosis codes should only be used for training or planning purposes until then.
