Answer: A
I63.30 is the appropriate code here as it is used to code cerebral infarction due to thrombosis of an unspecified cerebral artery.
Option B is not correct because I63.11 codes for cerebral infarction due to embolism of the vertebral artery. Here, embolism is not seen in the vertebral artery.
Option C is not correct because I63.41 codes for cerebral infarction due to the middle cerebral artery’s embolism, which is not seen here.
Option D is not correct because I63.12 codes for cerebral infarction when it is caused due to the embolism of a basilar artery. This is not seen in this patient.
