The patient is admitted through the ED with symptoms suggestive of a CVA. She smokes about one pack per day and takes metoprolol (Lopressor) for hypertension. An MRI is obtained that confirms an occlusion of the posterior cerebral artery with infarction. The patient undergoes carotid Doppler studies that indicate right carotid artery stenosis. She is discharged in stable condition on Day 4. Discharge diagnoses: occlusion of the posterior cerebral artery with infarction, right carotid artery stenosis, smoker, and hypertension. What is the coding and sequencing for this case?
