About 04780ZZ

04780ZZ is the ICD-10-PCS code for a dilation procedure on the colic artery, middle using an open 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 04700ZZ (abdominal aorta), 04710ZZ (celiac artery), 04720ZZ (gastric artery), 04730ZZ (hepatic artery), 04740ZZ (splenic artery), 04750ZZ (superior mesenteric artery) and 24 more.

The same procedure with a different approach is coded 04783ZZ (percutaneous) and 04784ZZ (percutaneous endoscopic).

With a different device, use 047804Z (intraluminal device, drug-eluting), 047805Z (intraluminal device, drug-eluting, two), 047806Z (intraluminal device, drug-eluting, three), 047807Z (intraluminal device, drug-eluting, four or more), 04780DZ (intraluminal device), 04780EZ (intraluminal device, two) and 2 more.
