Carotid Artery to Subclavian Artery Transposition
After a patient suffered a vertebrobasilar stroke, it was determined that there was a large amount of soft atheroma in the proximal left subclavian artery coming to within 5 to 6 mm of the vertebral artery. A left carotid artery to subclavian artery transposition was performed. The subclavian artery was transected and oversewn. Next, an arteriotomy was made in the carotid artery and an end-to-side anastomosis was performed between the common carotid artery and subclavian artery. Would the root operation for this procedure be Bypass or Reposition? ...

Article Overview
This premium article discusses a vascular surgery case involving a carotid-to-subclavian transposition after vertebrobasilar stroke and explores how the procedure is classified in ICD-10-PCS. It is intended for coders, CDI professionals, and other reimbursement staff who need to understand procedure classification in vascular cases and the general coding basis used for this type of operation.
Why This Topic Matters
Procedures involving arterial transposition can be difficult to classify correctly in ICD-10-PCS because the operation performed may not match the terminology used in the operative note. This article helps readers understand the coding context for a vascular surgery case and why precise procedure classification matters.
