ICD-10 Code H81.8X2 – Other disorders of vestibular function, left ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H81.8X2 – Other disorders of vestibular function, left ear
What it is
This code identifies a vestibular disorder affecting the left ear when the specific condition is not otherwise classified. Use it when documentation points to left-sided vestibular dysfunction but does not name a more specific diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Commonly noted findings include dizziness, vertigo, imbalance, or abnormal vestibular testing limited to the left ear.
When to use this code
Use H81.8X2 when the provider documents another or unspecified vestibular function disorder in the left ear. It is appropriate when the record supports left-sided vestibular involvement but does not support a more specific vestibular diagnosis.
Check laterality carefully and code from the provider’s diagnosis, not from symptoms alone. If the note only says vertigo, dizziness, or balance problems without a vestibular disorder, you need clearer documentation.
Do not use for
Do not use this code for nonspecific dizziness, syncope, or general gait instability without a documented vestibular disorder. Do not use it when the right ear, bilateral ear, or a more specific vestibular diagnosis is documented.
Coding tip
Verify that the chart explicitly supports left-ear vestibular dysfunction before assigning H81.8X2.
