About 027204Z
027204Z is the ICD-10-PCS code for a dilation procedure on the coronary artery, three arteries using an open 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 three vessels, insertion of one vascular stent, open chest coronary artery angioplasty and 1 more, the ICD-9-CM procedure titles it maps to (00.42, 00.45, 36.03 and 1 more).
For a different body part, codes include 027004Z (coronary artery, one artery), 027104Z (coronary artery, two arteries), 027304Z (coronary artery, four or more arteries), 027F04Z (aortic valve), 027G04Z (mitral valve), 027H04Z (pulmonary valve) and 11 more.
The same procedure with a different approach is coded 027234Z (percutaneous) and 027244Z (percutaneous endoscopic).
With a different device, use 027205Z (intraluminal device, drug-eluting, two), 027206Z (intraluminal device, drug-eluting, three), 027207Z (intraluminal device, drug-eluting, four or more), 02720DZ (intraluminal device), 02720EZ (intraluminal device, two), 02720FZ (intraluminal device, three) and 3 more.
It is an operating-room procedure in the MS-DRG logic for DRG 228 (Other Cardiothoracic Procedures with MCC) and DRG 229 (Other Cardiothoracic Procedures without MCC), under the surgical category “Other Cardiothoracic Procedures”.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
