ICD-10 Code H93.3 – Disorders of acoustic nerve (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H93.3 – Disorders of acoustic nerve
What it is
H93.3 identifies disorders affecting the acoustic nerve, also called the vestibulocochlear nerve. Use it when documentation describes a non-specific nerve disorder involving hearing or balance pathways.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings may include hearing loss, tinnitus, vertigo, or other auditory and balance complaints linked to eighth nerve dysfunction.
When to use this code
Use H93.3 when the provider documents a disorder of the acoustic nerve without a more specific diagnosis. It may apply when symptoms are attributed to the nerve, but the exact cause is not stated. Code the documented condition as written and avoid assuming laterality or etiology.
Do not use for
Do not use this code for general hearing loss, tinnitus, or vertigo unless the record specifically links them to the acoustic nerve. Check documentation if a more precise neurologic, otologic, or neoplastic diagnosis is given.
Coding tip
If the note only lists symptoms, query for a confirmed acoustic nerve disorder before assigning H93.3.
