ICD-10 Code H81.93 – Unspecified disorder of vestibular function, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H81.93 – Unspecified disorder of vestibular function, bilateral
What it is
H81.93 identifies a bilateral vestibular problem affecting balance and spatial orientation when the exact disorder is not specified. Use it when documentation confirms vestibular dysfunction on both sides but does not name a more precise diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include dizziness, imbalance, unsteady gait, or difficulty with head movement, but the chart should support bilateral vestibular involvement.
When to use this code
Use this code when the provider documents bilateral vestibular dysfunction, vestibular hypofunction, or a similar nonspecific disorder and does not identify a more exact cause. It is also appropriate when the record lacks enough detail to code a specific vestibular diagnosis. Check documentation if laterality or etiology is unclear.
Do not use for
Do not use H81.93 for unilateral vestibular disorders, vertigo without documented vestibular dysfunction, or a clearly named vestibular diagnosis with a more specific code. Do not assign it when documentation does not support bilateral involvement.
Coding tip
Verify that the record states both vestibular function and bilateral involvement before assigning H81.93.
