ICD-10 Code H81.8X1 – Other disorders of vestibular function, right ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H81.8X1 – Other disorders of vestibular function, right ear
What it is
This code identifies a vestibular disorder affecting the right ear that does not fit a more specific diagnosis. Use it when the chart documents a right-sided inner ear balance problem, but the exact vestibular condition is not named.
Clinical signs
Typical findings include vertigo, dizziness, imbalance, or unsteady gait related to the right ear. Clinical features vary; refer to documentation for the specific vestibular complaint or exam findings.
When to use this code
Use H81.8X1 when the clinician documents another or unspecified vestibular disorder of the right ear and no more specific code applies. It may support cases where balance symptoms are localized to the right ear but the exact cause remains unclear. Check documentation for laterality and specificity.
Do not use for
Do not use this code for left ear, bilateral, or unspecified vestibular disorders. Also avoid it when the record supports a more specific vestibular diagnosis, such as a named syndrome or confirmed peripheral cause.
Coding tip
Verify that the provider documents right ear involvement; laterality is required for accurate code selection.
