Benign paroxysmal vertigo, bilateral

This code represents a form of vertigo characterized by brief, recurrent episodes of dizziness or spinning sensations triggered by specific head movements, affecting both ears. It is caused by dislodged otoconia (calcium carbonate crystals) within the semicircular canals. Patients typically experience these symptoms without other neurological deficits.

Use this code when documentation clearly indicates benign paroxysmal positional vertigo (BPPV) affecting both the left and right vestibular systems. This diagnosis is often supported by a positive Dix-Hallpike maneuver on both sides and a history consistent with positional vertigo. It is appropriate when the provider explicitly states "bilateral BPPV" or similar.

• Ensure documentation specifies "bilateral" involvement; otherwise, use the appropriate unilateral code (H81.11 or H81.12).
• Do not confuse with other forms of vertigo, such as Meniere's disease (H81.0-) or central vertigo (R42).
• Code any associated symptoms, such as nausea or nystagmus, separately if they are significant and documented.
