About 04773ZZ

04773ZZ is the ICD-10-PCS code for a dilation procedure on the left colic artery using a percutaneous approach. 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 04703ZZ (abdominal aorta), 04713ZZ (celiac artery), 04723ZZ (gastric artery), 04733ZZ (hepatic artery), 04743ZZ (splenic artery), 04753ZZ (superior mesenteric artery) and 24 more.

The same procedure with a different approach is coded 04770ZZ (open) and 04774ZZ (percutaneous endoscopic).

With a different device, use 047734Z (intraluminal device, drug-eluting), 047735Z (intraluminal device, drug-eluting, two), 047736Z (intraluminal device, drug-eluting, three), 047737Z (intraluminal device, drug-eluting, four or more), 04773DZ (intraluminal device), 04773EZ (intraluminal device, two) and 2 more.

It is an operating-room procedure in the MS-DRG logic for DRG 037 (Extracranial Procedures with MCC), DRG 038 (Extracranial Procedures with CC), DRG 039 (Extracranial Procedures without CC/MCC), DRG 166 (Other Respiratory System O.R. Procedures with MCC), DRG 167 (Other Respiratory System O.R. Procedures with CC) and DRG 168 (Other Respiratory System O.R. Procedures without CC/MCC), under the surgical categories “Extracranial Procedures”, “Other Respiratory System O.R. Procedures”, “Other Vascular Procedures” and 8 more.
