About 04794GZ

04794GZ is the ICD-10-PCS code for a dilation procedure on the right renal artery using a percutaneous endoscopic approach with intraluminal device, four or more. 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 four or more vascular stents, angioplasty of other non-coronary vessel(s) and 1 more, the ICD-9-CM procedure titles it maps to (00.40, 00.48, 39.50 and 1 more).

For a different body part, codes include 04704GZ (abdominal aorta), 04714GZ (celiac artery), 04724GZ (gastric artery), 04734GZ (hepatic artery), 04744GZ (splenic artery), 04754GZ (superior mesenteric artery) and 24 more.

The same procedure with a different approach is coded 04790GZ (open) and 04793GZ (percutaneous).

With a different device, use 047944Z (intraluminal device, drug-eluting), 047945Z (intraluminal device, drug-eluting, two), 047946Z (intraluminal device, drug-eluting, three), 047947Z (intraluminal device, drug-eluting, four or more), 04794DZ (intraluminal device), 04794EZ (intraluminal device, two) and 2 more.

It is an operating-room procedure in the MS-DRG logic for DRG 252 (Other Vascular Procedures with MCC), DRG 253 (Other Vascular Procedures with CC) and DRG 254 (Other Vascular Procedures without CC/MCC), under the surgical category “Other Vascular Procedures”.
