ICD-10 Code H83.2X3 – Labyrinthine dysfunction, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H83.2X3 – Labyrinthine dysfunction, bilateral
What it is
Use this code for dysfunction of both labyrinths, the balance organs of the inner ear. It indicates a bilateral inner ear disorder affecting vestibular function, not a specific cause.
Clinical signs
Common features include dizziness, vertigo, imbalance, or motion intolerance related to vestibular dysfunction. Clinical features vary; refer to documentation.
When to use this code
Use H83.2X3 when the provider documents bilateral labyrinthine dysfunction, bilateral vestibular disorder, or equivalent wording. This code fits cases where the disorder is in both ears and no more specific diagnosis is recorded. Check documentation if the cause or laterality is unclear.
Do not use for
Do not use this code for unilateral labyrinthine dysfunction or for nonspecific dizziness without a documented inner ear disorder. Do not assign it when a different vestibular diagnosis is explicitly stated.
Coding tip
Verify that the record clearly states bilateral involvement before assigning H83.2X3.
