Labyrinthine dysfunction, left ear

This code signifies an impairment in the function of the labyrinth, the inner ear structure responsible for balance and hearing, specifically affecting the left ear. This dysfunction can manifest as vertigo, dizziness, imbalance, or nystagmus due to issues within the vestibular system.

Use this code when documentation clearly indicates a diagnosis of labyrinthine dysfunction localized to the left ear. This is appropriate for conditions such as labyrinthitis, vestibular neuronitis, or other inner ear disorders causing balance disturbances, provided the laterality is specified as left.

• Ensure the medical record explicitly states "left ear" to support this specific laterality.
• Distinguish from generalized labyrinthine dysfunction (H83.2X9) or right ear involvement (H83.2X1).
• Code any underlying cause or associated symptoms (e.g., vertigo, nausea) separately if documented.
