About 04703ZZ
04703ZZ is the ICD-10-PCS code for a dilation procedure on the abdominal aorta 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 04713ZZ (celiac artery), 04723ZZ (gastric artery), 04733ZZ (hepatic artery), 04743ZZ (splenic artery), 04753ZZ (superior mesenteric artery), 04763ZZ (right colic artery) and 24 more.
The same procedure with a different approach is coded 04700ZZ (open) and 04704ZZ (percutaneous endoscopic).
With a different device, use 047034Z (intraluminal device, drug-eluting), 047035Z (intraluminal device, drug-eluting, two), 047036Z (intraluminal device, drug-eluting, three), 047037Z (intraluminal device, drug-eluting, four or more), 04703DZ (intraluminal device), 04703EZ (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.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
