ICD-10 Code H83.19 – Labyrinthine fistula, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H83.19 – Labyrinthine fistula, unspecified ear
What it is
H83.19 identifies a labyrinthine fistula involving the inner ear, but the affected ear is not specified. This code is used when the record documents a fistula without laterality detail.
Clinical signs
Typical findings may include vertigo, dizziness, hearing changes, or symptoms triggered by pressure or sound. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents a labyrinthine fistula and does not state right or left ear. It also fits when the diagnosis is confirmed but the note lacks laterality. If the chart names another ear disorder as the primary problem, check documentation.
Do not use for
Do not use it when the affected ear is documented, because a laterality-specific code may apply. Do not assign it for nonspecific dizziness or hearing loss without a documented labyrinthine fistula.
Coding tip
Review operative notes, imaging, and ENT assessments for laterality before defaulting to unspecified ear.
