Labyrinthitis, left ear

This code signifies inflammation of the labyrinth in the inner ear, specifically affecting the left side. This condition typically presents with acute onset vertigo, nausea, vomiting, and sometimes hearing loss or tinnitus. It is often viral in origin but can also be bacterial.

Apply this code when documentation clearly indicates a diagnosis of labyrinthitis localized to the patient's left ear. Supporting documentation should detail symptoms consistent with inner ear inflammation, such as unilateral vertigo, nystagmus, and potentially associated hearing changes.

• Ensure laterality is explicitly documented as "left ear" to support this specific code.
• Distinguish from vestibular neuronitis (H81.2-) which involves inflammation of the vestibular nerve without hearing loss.
• Code any associated symptoms, such as vertigo (R42) or tinnitus (H93.1-), as secondary diagnoses if documented.
