Vertiginous syndromes in diseases classd elswhr, left ear

This code signifies a left-sided vertiginous syndrome that is a manifestation of an underlying disease process coded elsewhere. It indicates dizziness or a sensation of spinning originating from the left ear, secondary to another primary diagnosis.

Use this code when documentation clearly specifies vertigo localized to the left ear, and the physician has identified an underlying systemic or other non-vestibular disease as the cause. Examples include vertigo due to Meniere's disease, labyrinthitis, or acoustic neuroma, where the primary condition is coded first.

• Always sequence the underlying disease causing the vertigo first, followed by this code.
• Ensure documentation specifies "left ear" and a clear link to an underlying condition.
• Do not use for idiopathic vertigo or vertigo of unspecified origin.
