ICD-10 Code H83.11 – Labyrinthine fistula, right ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H83.11 – Labyrinthine fistula, right ear
What it is
H83.11 identifies a labyrinthine fistula in the right ear. This means there is an abnormal opening affecting the inner ear structures on the right side.
Clinical signs
Clinical features vary; refer to documentation. Commonly documented findings include vertigo, dizziness, hearing changes, or symptoms triggered by pressure or sound.
When to use this code
Use H83.11 when the provider documents a labyrinthine fistula limited to the right ear. Apply it for confirmed right-sided cases, including operative, imaging, or specialist documentation that specifies the side.
Do not assume laterality from symptoms alone. If the record does not clearly identify the right ear, check documentation before coding.
Do not use for
Do not use this code for unspecified ear involvement or for conditions that are only suspected. Check documentation if the note describes a different inner ear disorder without a fistula.
Coding tip
Always verify laterality and the exact term “labyrinthine fistula” before assigning H83.11.
