Cerebral infrc due to thombos of right post cerebral artery

This code signifies a cerebral infarction, commonly known as an ischemic stroke, that has occurred specifically due to a blood clot (thrombosis) obstructing the right posterior cerebral artery. This type of stroke typically affects areas of the brain supplied by this artery, which can include the occipital lobe, leading to visual field defects, and parts of the temporal lobe and thalamus.

Use this code when documentation clearly indicates an acute cerebral infarction caused by thrombosis, with specific laterality and vessel involvement of the right posterior cerebral artery. This diagnosis is typically supported by imaging studies (e.g., MRI, CT scan) confirming infarction and often angiography or MRA identifying the thrombotic occlusion.

• Ensure documentation specifies "thrombosis" as the cause, not embolism or unspecified occlusion, for accurate code assignment.
• Verify laterality (right) and specific vessel (posterior cerebral artery) are explicitly stated in the physician's notes.
• This code is for an initial or subsequent encounter for the acute infarction; do not use for sequelae of a past stroke.
