Thanks, SOC. As I read this version of ICD-10-CM, PVS is classified in Chapter 6 under "Diseases of the Nervous System" at G93.3. It subsumes CFS (also
known as ME), and it's “applicable” to benign myalgic encephalomyelitis:
2013 ICD-10-CM Diagnosis Code G93.3
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 code that can be used to specify a diagnosis.
- ICD-10-CM officially replaces ICD-9-CM on October 1, 2014, therefore, G93.3 and all ICD-10-CM diagnosis codes should only be used for training or planning purposes until then.
Applicable To
- Benign myalgic encephalomyelitis
Type 1 Excludes
- chronic fatigue syndrome NOS (R53.82)
Meanwhile, the National Alliance for Myalgic Encephalomyelitis
recommends that ME be diagnosed under ICD-9-CM: "According to a CDC ICD coding representative (July 2006), '
M.E. has always been indexed to code 323.9. That is the code number that patients should be assigned. Correctly diagnosing this disease benefits patients and health care providers by acknowledging the true prevalence of ME in the U.S.'"
2013 ICD-9-CM Diagnosis Codes >
Diseases Of The Nervous System And Sense Organs 320-389 >
Inflammatory Diseases Of The Central Nervous System 320-327 >
Encephalitis myelitis and encephalomyelitis 323-
2013 ICD-9-CM Diagnosis Code 323.9
Unspecified causes of encephalitis, myelitis, and encephalomyelitis
- ICD-9-CM 323.9 is a billable medical code that can be used to specify a diagnosis on a reimbursement claim.
ICD-9-CM 323.9
converts approximately to:
2013 ICD-10-CM Diagnosis Codes > Diseases of the nervous system
G00-G99 > Inflammatory diseases of the central nervous system
G00-G09 > Encephalitis, myelitis and encephalomyelitis
G04-
ME would seem, then, to qualify as a smaller population of patients with an orphan condition, deserving the attention of the FDA "office of orphan products." With reference to the ICC, we'd "be able to articulate what the subpopulation is."
