Labyrinthine dysfunction, right ear

This code signifies an abnormal or impaired function of the labyrinth in the right ear, which is the inner ear structure responsible for balance and hearing. This dysfunction can lead to symptoms such as vertigo, dizziness, imbalance, and nystagmus, impacting a patient's spatial orientation and equilibrium.

Apply this code when documentation clearly indicates a diagnosis of labyrinthine dysfunction specifically affecting the right ear. This diagnosis is typically made based on patient symptoms, physical examination findings (e.g., Dix-Hallpike maneuver), and diagnostic tests such as electronystagmography (ENG) or videonystagmography (VNG) confirming a right-sided abnormality.

• Ensure laterality is explicitly documented as "right ear" to support this specific code.
• Distinguish from other inner ear disorders like Meniere's disease (H81.0-) or benign paroxysmal positional vertigo (H81.1-) if the documentation points to a more specific diagnosis.
• Consider sequencing this code as a primary diagnosis if it is the main reason for the encounter, or as a secondary diagnosis if it's a comorbidity contributing to the patient's overall condition.
