Vertiginous syndromes in diseases classd elswhr, bilateral

This code signifies a type of vertigo that arises as a symptom or complication of another underlying medical condition, affecting both sides of the vestibular system. It indicates that the primary disease, not the vertigo itself, is the main diagnostic focus, with the bilateral vertigo being a manifestation of that primary condition.

Apply this code when documentation clearly states bilateral vertiginous symptoms are secondary to another specified disease, such as a neurological disorder, systemic infection, or metabolic condition. The medical record must explicitly link the bilateral vertigo to the primary diagnosis, which should be coded first.

• Always sequence the underlying disease first, as this code is for a manifestation.
• Ensure documentation specifies "bilateral" involvement; otherwise, consider other vertigo codes.
• Do not use if the vertigo is idiopathic or not clearly linked to another classified disease.
