Cerebral infrc due to thombos of left post cerebral artery

This code signifies a stroke resulting from a blockage (thrombosis) within the left posterior cerebral artery, leading to tissue death in the brain region supplied by this vessel. It specifically identifies an ischemic stroke caused by a localized clot formation.

Apply this code when documentation clearly indicates an acute cerebral infarction due to a thrombotic occlusion of the left posterior cerebral artery. This diagnosis is typically supported by imaging studies (e.g., MRI, CT scan) confirming the infarction and the specific vessel involvement, along with neurological deficits consistent with a posterior circulation stroke.

• Ensure documentation specifies "thrombosis" as the cause of the infarction, not an embolism or unspecified occlusion.
• Verify the laterality (left) and the specific artery (posterior cerebral artery) are clearly stated in the physician's notes.
• Sequence this code as the principal diagnosis when it is the primary reason for the encounter, followed by any associated neurological deficits.
