What 37216 covers

Code 37216 identifies percutaneous catheter placement of one or more stents in a cervical carotid artery without distal embolic protection. It is used for endovascular treatment of carotid narrowing and is typically performed by a vascular surgeon, interventional radiologist, or neurointerventional specialist in an angiography suite or catheterization laboratory.

Medicare physician fee schedule status N identifies this service as not covered by Medicare. The key distinction from 37215 is whether distal embolic protection is used: 37216 describes carotid stenting without it, while 37215 describes stenting with it. The code concerns treatment of the cervical carotid artery, not stenting of the intrathoracic common carotid or innominate artery.
