ICD-10 Code H81.31 – Aural Vertigo (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H81.31 – Aural vertigo
What it is
H81.31 identifies aural vertigo, a vertigo syndrome associated with the ear. Use it when documentation specifically links the dizziness or spinning sensation to an otologic cause.
Clinical signs
Clinical features vary; refer to documentation. Typical notes may mention vertigo, imbalance, or ear-related findings such as hearing or ear symptoms when the provider attributes the episode to the ear.
When to use this code
Use H81.31 when the clinician documents aural vertigo or clearly states that vertigo is ear-related. It fits encounters focused on evaluating or coding that specific diagnosis, not vague dizziness alone. Check documentation if the cause is not stated.
Do not use for
Do not use this code for nonspecific dizziness, syncope, or vertigo with another documented cause. If the record does not support an ear-related origin, choose the more accurate diagnosis.
Coding tip
Code only when the provider links vertigo to the ear; otherwise, query or use the documented symptom.
