ICD-10 Code H81.90 – Unspecified disorder of vestibular function, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H81.90 – Unspecified disorder of vestibular function, unspecified ear
What it is
H81.90 identifies a vestibular disorder affecting balance and spatial orientation, but the ear side is not specified. Use it when documentation confirms vestibular dysfunction without naming a more precise diagnosis.
Clinical signs
Typical features include dizziness, vertigo, imbalance, or unsteadiness. Clinical features vary; refer to documentation, especially when the record does not identify a specific vestibular disorder.
When to use this code
Use this code when the provider documents an unspecified vestibular dysfunction and does not state the affected ear. It may also fit when symptoms suggest vestibular involvement, but the record lacks enough detail for a more specific code. Check documentation before assigning it.
Do not use for
Do not use H81.90 if the chart identifies a more specific vestibular diagnosis or laterality. Do not use it for non-vestibular causes of dizziness without provider confirmation.
Coding tip
If the note names the ear or a specific vestibular condition, code that instead of this unspecified option.
