ICD-10 Code H81 – Disorders of vestibular function (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H81 – Disorders of vestibular function
What it is
H81 covers disorders affecting the vestibular system, which helps control balance and spatial orientation. Use it for documented vestibular dysfunction when the record does not specify a more exact diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Commonly recorded findings include vertigo, dizziness, imbalance, or nystagmus when these are linked to vestibular dysfunction.
When to use this code
Use H81 when the clinician documents a vestibular disorder but does not name a more specific condition such as Ménière disease or benign positional vertigo. It is also appropriate when the chart only supports a general vestibular dysfunction diagnosis. Check documentation if laterality or a more specific subtype is stated.
Do not use for
Do not use H81 for nonspecific dizziness without a documented vestibular disorder. Also avoid it when the record identifies a different cause, such as ear infection, stroke, or a specified vestibular diagnosis.
Coding tip
Code the most specific vestibular diagnosis available; if the note is vague, H81 is the fallback only when vestibular dysfunction is clearly documented.
