027337Z is the ICD-10-PCS code for a dilation procedure on the coronary artery, four or more arteries using a percutaneous approach with intraluminal device, drug-eluting, four or more. In ICD-10-PCS, dilation means expanding an orifice or the lumen of a tubular body part.

The same procedure with a different approach is coded 027307Z (open) and 027347Z (percutaneous endoscopic).

With a different device, use 027334Z (intraluminal device, drug-eluting), 027335Z (intraluminal device, drug-eluting, two), 027336Z (intraluminal device, drug-eluting, three), 02733DZ (intraluminal device), 02733EZ (intraluminal device, two), 02733FZ (intraluminal device, three) 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 321 (Percutaneous Cardiovascular Procedures with Intraluminal Device with MCC or 4+ Arteries/Intraluminal Devices), DRG 322 (Percutaneous Cardiovascular Procedures with Intraluminal Device without MCC), DRG 323 (Coronary Intravascular Lithotripsy with Intraluminal Device with MCC) and DRG 324 (Coronary Intravascular Lithotripsy with Intraluminal Device without MCC), under the surgical categories “”, “Percutaneous cardiovascular procedures with intraluminal device”, “Coronary Intravascular Lithotripsy with Intraluminal Device” and 1 more.

It was added in FY2017, effective October 1, 2016.
