Vertigo of central origin

This code describes a type of vertigo that arises from a dysfunction within the central nervous system, rather than the inner ear. Patients typically experience a sensation of spinning or imbalance, often accompanied by other neurological symptoms such as diplopia, ataxia, or dysarthria, indicating a brainstem or cerebellar lesion.

Use this code when documentation clearly indicates vertigo stemming from a central nervous system pathology, such as stroke, demyelinating disease, tumor, or migraine-associated vertigo. Supporting documentation should include neurological examination findings, imaging results (e.g., MRI of the brain), and a physician's definitive diagnosis differentiating it from peripheral causes.

• Differentiate carefully from peripheral vertigo (e.g., Meniere's disease, BPPV), which originates in the inner ear.
• Always sequence this code after the underlying central nervous system condition if known and actively treated.
• Ensure the medical record explicitly states "central origin" or provides sufficient clinical detail to support this distinction.
