Vestibular neuronitis
ICD-10 H81.2 is a billable code used to indicate a diagnosis of vestibular neuronitis.
Vestibular neuronitis is an acute vestibular disorder characterized by sudden onset of vertigo, often accompanied by nausea and imbalance, without auditory symptoms. It is believed to be caused by viral infections, commonly following upper respiratory tract infections. Patients typically present with intense spinning sensations that can last for days, and they may experience difficulty with balance and coordination. Unlike Meniere's disease, vestibular neuronitis does not involve hearing loss. Diagnosis is primarily clinical, supported by history and physical examination, including the head impulse test and other vestibular function tests. MRI may be utilized to rule out central causes of vertigo. Management focuses on symptomatic relief, often using vestibular suppressants and antiemetics, while vestibular rehabilitation therapy may be recommended for persistent symptoms. The prognosis is generally favorable, with most patients recovering fully within weeks to months.

Document the specific tests performed and the rationale for testing.
Otolaryngologists and neurologists should ensure comprehensive documentation of findings.
Common symptoms include sudden onset of vertigo, nausea, vomiting, and imbalance, typically without hearing loss.
Diagnosis is primarily clinical, based on patient history and physical examination, often supplemented by vestibular function tests and imaging to rule out other conditions.
