02734Z6Dilation of Coronary Artery, Four or More Arteries, Bifurcation, Percutaneous Endoscopic Approach

02734Z6 is the ICD-10-PCS code for a dilation procedure on the coronary artery, four or more arteries using a percutaneous endoscopic approach (qualifier: bifurcation). 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 four or more vessels, procedure on vessel bifurcation and percutaneous transluminal coronary angioplasty [PTCA], the ICD-9-CM procedure titles it maps to (00.43, 00.44 and 00.66).

For a different body part, codes include 02704Z6 (coronary artery, one artery), 02714Z6 (coronary artery, two arteries) and 02724Z6 (coronary artery, three arteries).

The same procedure with a different approach is coded 02730Z6 (open) and 02733Z6 (percutaneous).

With a different device, use 0273446 (intraluminal device, drug-eluting), 0273456 (intraluminal device, drug-eluting, two), 0273466 (intraluminal device, drug-eluting, three), 0273476 (intraluminal device, drug-eluting, four or more), 02734D6 (intraluminal device), 02734E6 (intraluminal device, two) and 3 more.

It is an operating-room procedure in the MS-DRG logic for DRG 231 (Coronary Bypass with PTCA with MCC), DRG 232 (Coronary Bypass with PTCA without MCC), DRG 250 (Percutaneous Cardiovascular Procedures without Intraluminal Device with MCC), DRG 251 (Percutaneous Cardiovascular Procedures without Intraluminal Device without MCC), DRG 321 (Percutaneous Cardiovascular Procedures with Intraluminal Device with MCC or 4+ Arteries/Intraluminal Devices) and DRG 322 (Percutaneous Cardiovascular Procedures with Intraluminal Device without MCC), under the surgical categories “”, “Percutaneous Cardiovascular Procedures without Intraluminal Device” and “Percutaneous cardiovascular procedures with intraluminal device”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
