ICD-10 Code H81.8X – Other disorders of vestibular function (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H81.8X – Other disorders of vestibular function
What it is
This code identifies vestibular disorders that affect balance and spatial orientation but do not fit a more specific vestibular diagnosis. Use it when the chart documents a nonspecific or other vestibular dysfunction.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include dizziness, vertigo, imbalance, or unsteady gait, with vestibular testing or exam notes suggesting inner ear dysfunction.
When to use this code
Use this code when the provider documents an “other” vestibular disorder, or when the condition is clearly vestibular but not named in a more specific ICD-10 option. It may also fit cases with persistent balance complaints and no better-defined diagnosis. Check documentation for laterality or a more specific vestibular disorder before coding.
Do not use for
Do not use this code for general dizziness, syncope, or neurologic causes of imbalance without vestibular documentation. If the record supports a more specific vestibular diagnosis, code that instead.
Coding tip
Look for the exact provider wording “other vestibular disorder” or equivalent before assigning H81.8X.
