Labyrinthitis, bilateral

This code signifies inflammation of the labyrinth in both inner ears. This bilateral inflammation typically results in symptoms such as vertigo, dizziness, nausea, and hearing loss affecting both sides.

Use this code when documentation explicitly states labyrinthitis affecting both the left and right inner ears. This diagnosis is supported by physician notes detailing bilateral vestibular symptoms and findings consistent with inflammation of the inner ear structures.

• Ensure the documentation clearly specifies "bilateral" involvement; otherwise, a unilateral code (H83.01 or H83.02) or unspecified code (H83.00) may be more appropriate.
• Distinguish from Meniere's disease (H81.0-), which has a different underlying pathology, though symptoms can overlap.
• Look for associated symptoms like bilateral hearing loss (H90.-) or tinnitus (H93.1-) to ensure all relevant conditions are captured.
