Cerebral infrc due to thombos of bilateral cereblr arteries

This code signifies a stroke resulting from a blockage caused by a blood clot forming within both cerebellar arteries. This type of infarction affects the cerebellum, which is responsible for coordination, balance, and motor control. The resulting neurological deficits can vary depending on the extent and location of the infarct.

Apply this code when documentation clearly indicates an ischemic stroke caused by thrombosis affecting both the left and right cerebellar arteries. Supporting documentation should specify the etiology as thrombosis and confirm the bilateral involvement of these specific vessels. This code is appropriate for both initial and subsequent encounters for this condition.

• Ensure the documentation explicitly states "bilateral" involvement of the cerebellar arteries; otherwise, a unilateral code may be more appropriate.
• Distinguish between thrombosis (clot formation in situ) and embolism (clot traveling from elsewhere) as different codes exist for each.
• Always sequence this code after any acute stroke symptom codes (e.g., hemiplegia) if present, as it represents the underlying cause.
