Cerebral infarction due to embolism of unsp cereblr artery

This diagnosis code signifies a stroke resulting from a blockage in an unspecified cerebellar artery, caused by an embolus originating elsewhere in the body. This embolic event leads to tissue death (infarction) in the cerebellum, impacting motor control, balance, and coordination.

Apply this code when documentation clearly indicates an embolic cerebral infarction affecting the cerebellum, but the specific cerebellar artery involved (e.g., superior, anterior inferior, posterior inferior) is not specified. Supporting documentation should include imaging reports (CT, MRI) confirming cerebellar infarction and a clinical assessment pointing to an embolic etiology.

• Ensure the documentation explicitly states "embolism" as the cause of the infarction. If thrombosis is indicated, a different code is required.
• Only use this code when the specific cerebellar artery is truly unspecified. If the artery is identified, a more specific code within the I63.4- series should be selected.
• Always sequence this code as the primary diagnosis if it is the reason for the encounter, followed by any associated conditions or sequelae.
