Ataxia following other cerebrovascular disease

This code signifies the presence of ataxia, a neurological sign characterized by impaired coordination of voluntary movements, that occurs as a sequela of a cerebrovascular event other than a stroke (e.g., transient ischemic attack, cerebral aneurysm rupture, or other non-stroke CVA). It indicates a persistent neurological deficit directly attributable to a past cerebrovascular disease.

Use this code when documentation clearly links current ataxia to a previous cerebrovascular incident that is not classified as a stroke. This applies to patients experiencing long-term balance and coordination issues following conditions like subarachnoid hemorrhage, intracerebral hemorrhage (non-traumatic), or cerebral infarction not specified as stroke. The medical record should explicitly state the causal relationship and the type of cerebrovascular disease.

• Always sequence this code after the code identifying the specific type of cerebrovascular disease (e.g., I60.-, I61.-, I67.-) that caused the ataxia.
• Ensure the documentation specifies "ataxia" as the neurological deficit; do not use for other post-CVA neurological deficits like hemiplegia or aphasia.
• Distinguish from ataxia due to current, active cerebrovascular disease (e.g., during an acute stroke), which would be coded with the acute stroke code and an additional code for ataxia if specified.
