Labyrinthine dysfunction, bilateral

This code signifies a functional impairment of the labyrinth, the inner ear structure responsible for balance and spatial orientation, affecting both ears. This dysfunction can manifest as vertigo, dizziness, imbalance, or nystagmus due to issues within the vestibular system.

Apply this code when documentation clearly indicates bilateral involvement of labyrinthine dysfunction. This is appropriate for conditions like bilateral Meniere's disease, bilateral vestibular neuritis, or other inner ear disorders causing balance issues in both ears. Supporting documentation should specify "bilateral" or describe symptoms and findings consistent with dysfunction in both labyrinths.

• Ensure documentation explicitly states "bilateral" or provides evidence of dysfunction in both ears; otherwise, unilateral codes or unspecified codes may be more appropriate.
• Do not confuse with codes for specific causes of labyrinthine dysfunction (e.g., Meniere's disease, ototoxicity), which should be coded first if known.
• Consider sequencing this code after the primary diagnosis if the labyrinthine dysfunction is a symptom or manifestation of another underlying condition.
