ICD-10 Code H81.92 – Unspecified disorder of vestibular function, left ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H81.92 – Unspecified disorder of vestibular function, left ear
What it is
This code identifies a vestibular disorder affecting the left ear when the specific cause is not documented. Use it for balance-system dysfunction localized to the left side, but not further defined.
Clinical signs
Typical findings include dizziness, vertigo, imbalance, or motion sensitivity related to vestibular dysfunction. Clinical features vary; refer to documentation.
When to use this code
Use H81.92 when the provider documents an unspecified vestibular disorder in the left ear and no more specific diagnosis is available. It is appropriate when the record supports left-sided vestibular involvement but does not name a definite condition.
Assign it only when laterality is documented and the diagnosis remains nonspecific. Check documentation if the chart instead describes a known inner ear disorder, hearing loss, or a central cause of dizziness.
Do not use for
Do not use this code for bilateral or right-sided vestibular disorders, or when a more specific vestibular diagnosis is documented. Do not use it for dizziness without a vestibular diagnosis.
Coding tip
Verify that “left ear” and “unspecified vestibular disorder” both appear in the record before assigning H81.92.
