Cerebral infarction due to thombos unsp cerebellar artery

This code signifies an ischemic stroke resulting from a blood clot (thrombosis) obstructing blood flow within an unspecified artery supplying the cerebellum. This leads to tissue death (infarction) in the cerebellar region of the brain.

Use this code when documentation clearly indicates a cerebral infarction caused by thrombosis, and the specific cerebellar artery involved is not identified. This code is appropriate for acute or subacute presentations of cerebellar stroke where the etiology is thrombotic.

• Ensure documentation specifies "thrombosis" as the cause of the infarction, not embolism or unspecified occlusion.
• If a specific cerebellar artery (e.g., superior, anterior inferior, posterior inferior) is documented, a more specific code should be used.
• Always sequence this code after any applicable codes for underlying conditions contributing to the thrombosis, such as atherosclerosis or hypercoagulable states.
