About 04774Z1

04774Z1 is the ICD-10-PCS code for a dilation procedure on the left colic artery using a percutaneous endoscopic approach (qualifier: drug-coated balloon). 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 and angioplasty of other non-coronary vessel(s), the ICD-9-CM procedure titles it maps to (00.40 and 39.50).

For a different body part, codes include 04704Z1 (abdominal aorta), 04714Z1 (celiac artery), 04724Z1 (gastric artery), 04734Z1 (hepatic artery), 04744Z1 (splenic artery), 04754Z1 (superior mesenteric artery) and 24 more.

The same procedure with a different approach is coded 04770Z1 (open) and 04773Z1 (percutaneous).

With a different device, use 0477441 (intraluminal device, drug-eluting) and 04774D1 (intraluminal device).

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”.

It was added in FY2018, effective October 1, 2017.
