Ataxia following unspecified cerebrovascular disease

This code signifies the presence of ataxia, a lack of voluntary coordination of muscle movements, occurring as a sequela of a cerebrovascular event where the specific type of cerebrovascular disease is not documented. It indicates a persistent neurological deficit impacting balance and coordination due to a prior stroke or other cerebrovascular insult.

Use this code when documentation clearly states ataxia as a residual effect of a cerebrovascular disease, but the specific nature of the cerebrovascular event (e.g., ischemic stroke, hemorrhagic stroke) is not specified. This is appropriate when the physician explicitly links the ataxia to a past CVA without further detail on the CVA type.

• Always attempt to query for a more specific type of cerebrovascular disease if possible, as this code represents an unspecified etiology.
• Sequence this code after the appropriate code for the cerebrovascular disease if it is still active or if the specific type is known and being reported.
• Ensure the documentation explicitly states "ataxia" and links it to a "cerebrovascular disease" or "CVA."
