ICD-10 Code H83.2X – Labyrinthine dysfunction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H83.2X – Labyrinthine dysfunction
What it is
This code identifies a disorder of the inner ear labyrinth. Use it when documentation states labyrinthine dysfunction without a more specific vestibular diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Commonly noted findings include vertigo, dizziness, imbalance, or other vestibular complaints linked to inner ear dysfunction.
When to use this code
Use H83.2X when the provider documents labyrinthine dysfunction as the diagnosis and does not specify a different ear or vestibular condition. It may also fit follow-up visits for persistent inner ear dysfunction when the diagnosis remains unchanged. Check documentation for laterality or added specificity, if available.
Do not use for
Do not use this code for nonspecific dizziness, syncope, or neurologic causes of imbalance. If the record supports a more specific vestibular or ear disorder, code that condition instead.
Coding tip
Verify that the note names labyrinthine dysfunction explicitly; if not, choose a more precise documented diagnosis.
