Cerebellar stroke syndrome

This code signifies a collection of neurological deficits resulting from an acute cerebrovascular event (stroke) affecting the cerebellum. Patients typically present with symptoms such as ataxia, nystagmus, dysarthria, and vertigo, reflecting damage to the cerebellar structures.

Apply this code when documentation clearly indicates a stroke localized to the cerebellum, leading to a recognizable syndrome. This diagnosis is supported by imaging studies (e.g., CT, MRI) confirming cerebellar infarction or hemorrhage, alongside a clinical presentation consistent with cerebellar dysfunction.

• Differentiate from other stroke types; ensure the documentation specifies cerebellar involvement.
• Always code the specific type of stroke (e.g., ischemic, hemorrhagic) as the primary diagnosis if known, with this code as a secondary diagnosis to specify the syndrome.
• Look for specific cerebellar signs and symptoms documented by the neurologist or physician to support the diagnosis.
