ICD-10 Code H83.2X1 – Labyrinthine dysfunction, right ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H83.2X1 – Labyrinthine dysfunction, right ear
What it is
This code identifies a disorder of the inner ear balance organ on the right side. It is used when the labyrinth is not functioning normally and the documentation specifies the right ear.
Clinical signs
Clinical features may include vertigo, dizziness, unsteadiness, or abnormal balance testing. Check documentation for the exact findings, because symptoms and exam results can vary by cause.
When to use this code
Use H83.2X1 when the provider documents labyrinthine dysfunction affecting the right ear and does not name a more specific diagnosis. It may fit records describing peripheral vestibular dysfunction, right-sided inner ear imbalance, or similar wording. If the note is nonspecific, verify laterality before coding.
Do not use for
Do not use this code for left ear, bilateral, or unspecified labyrinthine dysfunction. Also avoid it when the chart supports a more specific vestibular, neurologic, or ear disorder. Check documentation.
Coding tip
Confirm that the right-sided laterality is documented explicitly before assigning H83.2X1.
