ICD-10 Code H83.91 – Unspecified disease of right inner ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H83.91 – Unspecified disease of right inner ear
What it is
H83.91 identifies a disorder of the right inner ear when the specific condition is not documented. Use it when the record confirms right-sided inner ear disease but does not name a more precise diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Common inner ear problems may include vertigo, hearing changes, tinnitus, or imbalance, but you should code only what is actually recorded.
When to use this code
Use this code when the provider documents an unspecified disease affecting the right inner ear and no more specific diagnosis is available. It is appropriate for incomplete assessments, referral notes, or encounters where the exact disorder is still under evaluation. If later documentation gives a specific condition, code that instead.
Do not use for
Do not use H83.91 for left-sided or bilateral inner ear disease, or when the diagnosis is a more specific ear disorder. Check documentation if the problem is external, middle ear, or not clearly inner ear related.
Coding tip
Assign H83.91 only when the record clearly states right inner ear disease and no more specific code applies.
