Benign paroxysmal vertigo, unspecified ear

This code represents a form of vertigo characterized by brief, sudden episodes of dizziness triggered by specific head movements. It is caused by dislodged otoconia (calcium carbonate crystals) in the semicircular canals of the inner ear, leading to a sensation of spinning or imbalance. The "unspecified ear" designation indicates that the laterality of the condition is not documented.

Use this code when the medical record clearly documents benign paroxysmal positional vertigo (BPPV) but does not specify whether it affects the left, right, or both ears. This diagnosis is typically supported by patient history of positional dizziness and a positive Dix-Hallpike maneuver without laterality specified.

• Avoid using this code if the medical record specifies the affected ear (e.g., right, left, or bilateral); instead, use the more specific codes.
• Ensure documentation supports the "benign paroxysmal" nature of the vertigo, differentiating it from other forms of dizziness.
• Consider sequencing this code as a primary diagnosis if it is the main reason for the encounter.
