ICD-10: H94.00

Acoustic neuritis, classified under ICD-10 code H94.00, refers to inflammation of the vestibulocochlear nerve (cranial nerve VIII), which is responsible for hearing and balance. This specific code is used when the condition is associated with infectious and parasitic diseases that are classified elsewhere, and it is noted as affecting an unspecified ear.

Clinical Description

Definition

Acoustic neuritis is characterized by the inflammation of the vestibulocochlear nerve, which can lead to symptoms such as hearing loss, tinnitus (ringing in the ears), and balance disturbances. The condition can arise as a complication of various infectious or parasitic diseases, which may not be directly related to the ear itself but can affect the nerve's function.

Symptoms

Patients with acoustic neuritis may experience:
- Hearing Loss: This can be partial or complete and may affect one or both ears.
- Tinnitus: A perception of sound when no external sound is present, often described as ringing, buzzing, or hissing.
- Balance Issues: Dizziness or vertigo may occur due to the nerve's role in maintaining equilibrium.

Etiology

The etiology of acoustic neuritis can be linked to several infectious agents, including:
- Viral Infections: Such as herpes simplex virus, varicella-zoster virus, and cytomegalovirus.
- Bacterial Infections: Certain bacterial infections can also lead to inflammation of the nerve.
- Parasitic Infections: Although less common, some parasitic diseases may affect the auditory system.

Diagnostic Considerations

Diagnostic Criteria

To diagnose acoustic neuritis, healthcare providers typically consider:
- Patient History: A thorough medical history to identify any recent infections or symptoms.
