ICD-10 Code H93.3X1 – Disorders of right acoustic nerve (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H93.3X1 – Disorders of right acoustic nerve
What it is
This code identifies a disorder affecting the right acoustic nerve, also called the vestibulocochlear nerve. It is used when documentation specifies a right-sided nerve problem rather than a general ear disorder.
Clinical signs
Clinical features vary; refer to documentation. Findings may include hearing changes, tinnitus, vertigo, or other symptoms attributed to dysfunction of the right acoustic nerve.
When to use this code
Use this code when the provider documents a disorder of the right acoustic nerve and laterality is clearly stated. It is appropriate for charted nerve pathology, neuritis, or other specified right-sided acoustic nerve conditions. Check documentation if the note only describes ear symptoms without naming the nerve.
Do not use for
Do not use it for unspecified hearing loss, general ear disease, or left-sided or bilateral acoustic nerve disorders. If the record does not confirm the right acoustic nerve, check documentation.
Coding tip
Always verify laterality and the exact nerve named in the provider note before assigning H93.3X1.
