Postviral and related fatigue syndromes
ICD-10 G93.3 is a billable code used to indicate a diagnosis of postviral and related fatigue syndromes.
Postviral and related fatigue syndromes encompass a range of conditions characterized by persistent fatigue following a viral infection. This syndrome can manifest as debilitating fatigue that is not alleviated by rest and is often accompanied by a variety of symptoms including pain syndromes, autonomic dysfunction, and cognitive impairments. Patients may experience myalgia, arthralgia, headaches, and sleep disturbances. Autonomic disorders may present as orthostatic intolerance, palpitations, and gastrointestinal symptoms. In some cases, postviral fatigue can lead to secondary complications such as hydrocephalus, where cerebrospinal fluid accumulation occurs, potentially exacerbating neurological symptoms. The pathophysiology is not fully understood but may involve immune dysregulation, neuroinflammation, and mitochondrial dysfunction. Diagnosis typically requires a thorough clinical evaluation, ruling out other conditions, and may involve symptom questionnaires and functional assessments. The complexity of this syndrome lies in its multifactorial nature, requiring a multidisciplinary approach for effective management.
Detailed neurological examination findings, history of viral infections, and symptomatology.
Patients presenting with fatigue, cognitive dysfunction, and pain post-viral illness.
Neurologists should document the impact of symptoms on daily functioning and any neurological assessments performed.
History of viral infections, laboratory results confirming viral etiology, and follow-up assessments.
Patients with a history of viral infections who develop prolonged fatigue and related symptoms.
Infectious disease specialists should document the timeline of infection and symptom onset to establish a clear connection.
Used for follow-up visits of patients with postviral fatigue syndromes.
Document the patient's history, symptom review, and any assessments performed.
Neurologists should include neurological assessments, while infectious disease specialists should document viral history.
Symptoms include persistent fatigue, pain syndromes, cognitive difficulties, and autonomic dysfunction following a viral infection.
G93.3 is specifically linked to a viral infection, while chronic fatigue syndrome has broader diagnostic criteria and may not have a clear viral trigger.
