ICD-10 Code H83.2X9 – Labyrinthine dysfunction, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H83.2X9 – Labyrinthine dysfunction, unspecified ear
What it is
This code identifies a disorder of the inner ear labyrinth when the affected ear is not specified. Use it for documented labyrinthine dysfunction without a more precise diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported findings include vertigo, dizziness, imbalance, or other vestibular complaints linked to inner ear dysfunction.
When to use this code
Use H83.2X9 when the provider documents labyrinthine dysfunction and does not name the side or a more specific inner ear disorder. It may fit visits for dizziness or balance problems when the record supports a labyrinthine cause. Check documentation if the ear is later identified.
Do not use for
Do not use this code for a clearly documented specific vestibular or cochlear diagnosis, or when another ear condition better explains the symptoms. Avoid it if the record does not support labyrinthine involvement.
Coding tip
Confirm whether the note specifies right, left, or bilateral ear involvement before selecting the unspecified code.
