ICD-10 Code H93.3X – Disorders of acoustic nerve (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H93.3X – Disorders of acoustic nerve
What it is
This code refers to disorders affecting the acoustic, or vestibulocochlear, nerve. Use it when documentation identifies a nerve-related ear condition rather than a middle ear or inner ear disease.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include hearing changes, tinnitus, dizziness, or balance complaints when the acoustic nerve is involved.
When to use this code
Use this code when the provider documents a disorder of the acoustic nerve, including unspecified nerve dysfunction affecting hearing or equilibrium. It may fit cases where the note names the nerve but does not define a more specific diagnosis. Check documentation for laterality or alternate etiologies.
Do not use for
Do not use it for routine hearing loss, vertigo, or ear pain unless the acoustic nerve disorder is specifically documented. Do not assign it when a different neurologic or otologic diagnosis is clearly stated.
Coding tip
If the note is vague, query for the exact nerve disorder before coding.
