Cerebral infarction due to thrombosis of r verteb art

This code signifies a stroke resulting from a blood clot obstructing the right vertebral artery, leading to tissue death in a part of the brain. It specifically identifies an ischemic stroke caused by a thrombus (stationary clot) within this particular vessel.

Apply this code when documentation clearly states a cerebral infarction (ischemic stroke) caused by thrombosis of the right vertebral artery. This diagnosis is typically supported by imaging studies (e.g., MRI, CT angiography) confirming the infarction and the location of the occlusive thrombus.

• Ensure documentation specifies "thrombosis" and not "embolism" or "unspecified occlusion" for the right vertebral artery.
• Verify laterality; this code is specific to the right vertebral artery.
• Sequence this code as the primary diagnosis when it is the reason for the encounter, followed by any associated neurological deficits.
