Cereb infrc due to unsp occls or stenosis of bi cereblr art

This code signifies brain tissue death (infarction) in both cerebellar hemispheres resulting from a blockage or narrowing of the arteries supplying these areas. The specific nature of the occlusion or stenosis (e.g., thrombus, embolus) is not documented or is unknown.

Apply this code when medical records clearly indicate an ischemic stroke affecting both cerebellar arteries, and the physician's documentation does not specify the type of occlusion or stenosis. Documentation should confirm the bilateral involvement and the infarction of cerebellar tissue.

• Ensure documentation explicitly states "bilateral" cerebellar artery involvement; otherwise, a unilateral code may be more appropriate.
• Only use this code when the specific cause of occlusion (e.g., thrombosis, embolism) is not identified by the provider.
• Always sequence this code after any acute stroke codes (I60-I67) if applicable, and consider any associated neurological deficits.
