Choose Appropriate Carotid Artery Stenosis Dx Code

Question: Which ICD-10-CM choices do I have for carotid artery stenosis?

Nebraska Subscriber

Answer: If your cardiologist provides adequate documentation, you will select the appropriate carotid artery stenosis code from the following choices based upon whether the stenosis is in the right, left, unspecified, bilateral carotid arteries:

  • I65.21 (Occlusion and stenosis of right carotid artery)
  • I65.22 (Occlusion and stenosis of left carotid artery)
  • I65.23 (Occlusion and stenosis of bilateral carotid arteries)

Don’t miss: If your cardiologist doesn’t specify the side of the patient’s carotid stenosis, you should report I65.29 (Occlusion and stenosis of unspecified carotid artery).
