ICD-10 Code H83.02 – Labyrinthitis, left ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H83.02 – Labyrinthitis, left ear
What it is
H83.02 identifies inflammation of the inner ear labyrinth on the left side. Use it when documentation specifically states left ear labyrinthitis.
Clinical signs
Typical findings include vertigo, dizziness, nausea, and balance disturbance. Hearing changes may occur; clinical features vary, so refer to documentation.
When to use this code
Use this code when the provider documents labyrinthitis affecting the left ear, or when laterality is clearly confirmed in the record. It may support coding for acute vestibular symptoms linked to inner ear inflammation. If the note only says “labyrinthitis” without side, check documentation.
Do not use for
Do not use for nonspecific dizziness, benign positional vertigo, or vestibular neuritis unless labyrinthitis is documented. Do not guess laterality.
Coding tip
Confirm both the diagnosis and the left-sided laterality in the provider note before assigning H83.02.
