Unspecified late effects of cerebrovascular disease

This code signifies the long-term, residual neurological deficits or complications that persist after an acute cerebrovascular event (e.g., stroke, transient ischemic attack) when the specific nature of these effects is not documented. It encompasses chronic conditions like hemiplegia, aphasia, or cognitive impairment, without further specification of the type or cause of the cerebrovascular disease.

Use this code when documentation clearly indicates "late effects of cerebrovascular disease" or "post-stroke syndrome" without specifying the exact nature of the original cerebrovascular event or the precise residual deficit. This is appropriate when the medical record lacks the detail to assign a more specific code for the sequelae.

• Avoid using this code if a more specific late effect code (e.g., hemiplegia following cerebral infarction) can be assigned.
• Always sequence this code after the code for the specific residual condition (e.g., aphasia, hemiplegia).
• Query the provider for more specific documentation if "unspecified late effects" is the only information available.
