Benign paroxysmal vertigo, left ear

This code signifies a specific type of vertigo characterized by brief, intense spinning sensations triggered by changes in head position, originating from the left inner ear. It results from dislodged otoconia (calcium carbonate crystals) within the semicircular canals.

Apply this code when documentation clearly indicates benign paroxysmal positional vertigo (BPPV) affecting the left ear. This diagnosis is typically made based on a positive Dix-Hallpike maneuver on the left side and the absence of other neurological deficits.

• Ensure the documentation explicitly states "left ear" or "left-sided" BPPV.
• Do not confuse with unspecified BPPV (H81.10) or BPPV affecting the right ear (H81.11).
• Look for supporting documentation of positional nystagmus and vertigo elicited by specific head movements.
