ICD-10 Code H81.8X9 – Other disorders of vestibular function, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H81.8X9 – Other disorders of vestibular function, unspecified ear
What it is
This code identifies a vestibular disorder affecting balance or spatial orientation when the ear is not specified. Use it for documented vestibular dysfunction that does not fit a more specific ICD-10-CM vestibular diagnosis.
Clinical signs
Typical findings include dizziness, vertigo, unsteadiness, or balance problems related to the vestibular system. Clinical features vary; refer to documentation.
When to use this code
Use H81.8X9 when the provider documents another vestibular disorder and does not identify the side or a more specific ear diagnosis. It also fits cases where the record states vestibular dysfunction, but the documentation is too limited for a more precise code.
Do not use for
Do not use this code for benign paroxysmal positional vertigo, Meniere disease, or vestibular neuritis when those are documented. Check documentation if the cause is known or if a more specific vestibular code applies.
Coding tip
Code from the provider’s exact wording and query for laterality or specificity if the record only says “vertigo” or “dizziness.”
