Transcarotid Arterial Catheterization
A patient underwent transcarotid arterial catheterization (TCAR) to treat right internal carotid artery stenosis. At surgery, a cutdown was made in the neck; the common carotid artery was accessed with a needle; a microwire was advanced; and the internal carotid artery was wired. The vessel was predilated with a balloon, the stent was landed and completion angiogram showed excellent results.

Article Overview
This premium article reviews a transcarotid arterial catheterization case used to treat carotid artery stenosis and focuses on the ICD-10-PCS approach assignment question raised by the operative steps. It is aimed at coders, CDI staff, and revenue cycle professionals who work with vascular procedures and ICD-10-PCS procedure coding guidance. The article also references Coding Clinic guidance as part of the discussion and presents the procedure code assignment associated with the case.
Why This Topic Matters
Transcarotid procedures can create uncertainty in ICD-10-PCS approach selection because the access route and the operative path may not align intuitively. Understanding how this type of case is framed helps coders apply procedure coding guidance consistently in vascular surgery scenarios.
