About 027334Z
027334Z 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. 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, insertion of one vascular stent, percutaneous transluminal coronary angioplasty [PTCA] and 1 more, the ICD-9-CM procedure titles it maps to (00.43, 00.45, 00.66 and 1 more).
For a different body part, codes include 027034Z (coronary artery, one artery), 027134Z (coronary artery, two arteries), 027234Z (coronary artery, three arteries), 027F34Z (aortic valve), 027G34Z (mitral valve), 027H34Z (pulmonary valve) and 11 more.
The same procedure with a different approach is coded 027304Z (open) and 027344Z (percutaneous endoscopic).
With a different device, use 027335Z (intraluminal device, drug-eluting, two), 027336Z (intraluminal device, drug-eluting, three), 027337Z (intraluminal device, drug-eluting, four or more), 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 has been valid since ICD-10-PCS took effect on October 1, 2015.
