Vertigo of central origin

This code signifies dizziness or a sensation of spinning that originates from a disorder within the central nervous system, such as the brainstem or cerebellum. Unlike peripheral vertigo, central vertigo often presents with additional neurological symptoms and may indicate a more serious underlying condition.

Apply this code when documentation clearly indicates vertigo caused by a central nervous system lesion or dysfunction, such as stroke, multiple sclerosis, or tumor. Supporting documentation should detail neurological findings, imaging results (e.g., MRI), and a physician's assessment differentiating it from peripheral causes.

• Differentiate carefully from peripheral vertigo (e.g., Meniere's disease, BPPV), which has distinct ICD-9 codes.
• Always look for documentation of associated neurological deficits (e.g., ataxia, diplopia, dysarthria) to support central origin.
• Sequence this code as a primary diagnosis when it is the reason for the encounter, or as a secondary diagnosis when it is a significant co-morbidity.
