H94.02
Acoustic neuritis in infectious and parasitic diseases classified elsewhere, left ear
Clinical Classification Guidelines
Medical Intelligence & Overview
Acoustic neuritis, also known as vestibular neuritis or labyrinthitis when involving the inner ear, is an inflammation of the vestibulocochlear nerve (the eighth cranial nerve). This nerve is responsible for transmitting sound and balance information from the inner ear to the brain. When affected, it can cause sudden hearing loss, dizziness, and balance problems. The specific ICD-10 code H94.02 refers to this condition affecting the left ear and occurring in the context of infectious and parasitic diseases classified elsewhere. It's essential to understand that this condition often arises due to infections or other underlying health issues that lead to inflammation of the nerve.
Causes & Symptoms
Clinical Causes: Viral infections such as herpes simplex virus or herpes zoster Bacterial infections leading to inner ear inflammation Other infectious or parasitic diseases affecting the nervous system Autoimmune responses causing nerve inflammation Complications following respiratory or systemic infections Spread of infections from nearby structures in the ear
Key Symptoms: Sudden or gradual hearing loss in the affected ear Dizziness or vertigo, often severe Imbalance or difficulty walking Nausea or vomiting associated with dizziness Abnormal eye movements (nystagmus) Possible ear ringing (tinnitus) Facial weakness or numbness (less common)
Diagnostic & Treatment
Diagnosis Path: Diagnosing acoustic neuritis involves a comprehensive clinical evaluation. Healthcare providers typically perform a physical exam focusing on balance, hearing, and neurological function. Tests may include:
Treatment Protocols: Management of acoustic neuritis depends on the underlying cause and severity of symptoms. Common approaches involve:
