03794EZ is the ICD-10-PCS code for a dilation procedure on the right ulnar artery using a percutaneous endoscopic approach with intraluminal device, two. In ICD-10-PCS, dilation means expanding an orifice or the lumen of a tubular body part.

In plain terms, this corresponds to procedure on single vessel, insertion of two vascular stents, angioplasty of other non-coronary vessel(s) and 1 more, the ICD-9-CM procedure titles it maps to (00.40, 00.46, 39.50 and 1 more).

The same procedure with a different approach is coded 03790EZ (open) and 03793EZ (percutaneous).

With a different device, use 037944Z (intraluminal device, drug-eluting), 037945Z (intraluminal device, drug-eluting, two), 037946Z (intraluminal device, drug-eluting, three), 037947Z (intraluminal device, drug-eluting, four or more), 03794DZ (intraluminal device), 03794FZ (intraluminal device, three) and 2 more.
