What 36100 covers
This code describes establishing entry into a carotid or subclavian artery with a needle or intracatheter. It may be used when direct access at one of these vessels is part of an angiographic or endovascular procedure. The record should identify the artery accessed and document that the access was actually performed; this is not a code for imaging or for catheter advancement to a separate target. Physicians and other qualified practitioners may perform the service in a procedural setting, including a hospital or ambulatory surgery center.
Select the code by the artery entered: carotid or subclavian access distinguishes it from direct access to an extremity artery or the aorta. Document the access site and the procedural circumstances supporting the service. When multiple procedures are performed in the same session, CMS pays the highest-valued procedure in full and the others at 50%. For bilateral reporting with modifier 50, CMS pays this procedure at 150%.
