World Health Organization

The World Health Organization (WHO) is "a specialized agency of the United Nations that is concerned with public health. It was established on 7 April 1948, and is headquartered in Geneva, Switzerland. The WHO is a member of the United Nations Development Group. Its predecessor, the Health Organization, was an agency of the League of Nations."

The International Statistical Classification of Diseases and Related Health Problems (ICD) is maintained by WHO.

ICD-10 is the 10th revision of the ICD. Different countries' government healthcare systems will use slightly different codes governed by the ICD.

WHO History with ME/CFS

Myalgic encephalomyelitis

Myalgic encephalomyelitis has been classified by the WHO as a neurological disease since 1969 and has occurred in both epidemic and sporadic form since at least the 1930s, although is probably much older.

United States

G93.3 houses Postviral fatigue syndrome and benign myalgic encephalomyelitis.

Chronic fatigue syndrome

Chronic fatigue syndrome is classified NOS "not otherwise specified". ICD 9 (and 10) "consider NOS the physician's fault: The documentation does not provide enough information to assign a more specific diagnosis code."

United States

ICD-10-CDC Diagnosis Code R53.82 is for Chronic fatigue, unspecified.

ICD-10-CM R53.82 is grouped within Diagnostic Related Group(s) (MS-DRG v35.0):

• 947 Signs and symptoms with mcc
• 948 Signs and symptoms without mcc

International Classification of Diseases (ICD) - A system of medical diagnostic codes, created by the World Health Organization (WHO), to classify diseases and other health related conditions for the purpose of international diagnostic consistency. By having common diagnostic codes around the world, health researchers are better able to quantify and track disease burdens. The most current version is called ICD-11. (Learn more: www.who.int)

myalgic encephalomyelitis (M.E.) - A disease often marked by neurological symptoms, but fatigue is sometimes a symptom as well. Some diagnostic criteria distinguish it from chronic fatigue syndrome, while other diagnostic criteria consider it to be a synonym for chronic fatigue syndrome. A defining characteristic of ME is post-exertional malaise (PEM), or post-exertional neuroimmune exhaustion (PENE), which is a notable exacerbation of symptoms brought on by small exertions. PEM can last for days or weeks. Symptoms can include cognitive impairments, muscle pain (myalgia), trouble remaining upright (orthostatic intolerance), sleep abnormalities, and gastro-intestinal impairments, among others. An estimated 25% of those suffering from ME are housebound or bedbound. The World Health Organization (WHO) classifies ME as a neurological disease.
