ICD-10 Code H83.2 – Labyrinthine dysfunction (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H83.2 – Labyrinthine dysfunction
What it is
H83.2 identifies dysfunction of the labyrinth, the inner ear structure involved in balance. Use it when documentation describes a labyrinthine disorder without a more specific diagnosis.
Clinical signs
Common findings include vertigo, dizziness, imbalance, or unsteady gait. Clinical features vary; refer to documentation, especially when the record does not specify a distinct vestibular diagnosis.
When to use this code
Use H83.2 when the provider documents labyrinthine dysfunction, labyrinthitis-like imbalance, or an inner ear balance problem that is not otherwise classified. It is appropriate when the note supports a labyrinth-related disorder but does not name a more precise condition. Check documentation if the cause is unclear.
Do not use for
Do not use this code for nonspecific dizziness without inner ear involvement. Also avoid it when the record identifies a different, more specific vestibular or ear diagnosis.
Coding tip
Code H83.2 only when the provider clearly links the symptoms to labyrinthine dysfunction.
