A 60-year-old woman presents to the ED because she is suddenly unable to speak. Following admission, she is found to be in atrial fibrillation. A CT scan of the head shows some old defects, but the aphasia was not present prior to this event. It is thought to be due to a recent cerebral embolus. The physician documented an NIHSS of 4. By the fifth day, she is stable and able to go home. The aphasia has cleared, and the fibrillation is controlled with medication. Discharge diagnoses: CVA due to cerebral embolism, atrial fibrillation. What is the coding and sequencing for the diagnoses in this case?
