ICD-10 Code H83.2X2 – Labyrinthine dysfunction, left ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H83.2X2 – Labyrinthine dysfunction, left ear
What it is
H83.2X2 identifies dysfunction of the labyrinth in the left ear. Use it when documentation states a left-sided inner ear balance or vestibular problem without a more specific diagnosis.
Clinical signs
Patients may have vertigo, dizziness, imbalance, or nystagmus related to left ear labyrinth involvement. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents labyrinthine dysfunction limited to the left ear and no more specific vestibular disorder is named. It also fits follow-up or evaluation notes that clearly attribute symptoms to the left labyrinth. Check documentation if laterality is not stated.
Do not use for
Do not use H83.2X2 for nonspecific dizziness without documented labyrinthine dysfunction. Do not use it when a different ear, bilateral disease, or a more specific inner ear diagnosis is recorded.
Coding tip
Confirm laterality in the note, because this code is specific to the left ear.
