About 02730ZZ

02730ZZ is the ICD-10-PCS code for a dilation procedure on the coronary artery, four or more arteries using an open 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 four or more vessels and open chest coronary artery angioplasty, the ICD-9-CM procedure titles it maps to (00.43 and 36.03).

For a different body part, codes include 02700ZZ (coronary artery, one artery), 02710ZZ (coronary artery, two arteries), 02720ZZ (coronary artery, three arteries), 027F0ZZ (aortic valve), 027G0ZZ (mitral valve), 027H0ZZ (pulmonary valve) and 11 more.

The same procedure with a different approach is coded 02733ZZ (percutaneous) and 02734ZZ (percutaneous endoscopic).

With a different device, use 027304Z (intraluminal device, drug-eluting), 027305Z (intraluminal device, drug-eluting, two), 027306Z (intraluminal device, drug-eluting, three), 027307Z (intraluminal device, drug-eluting, four or more), 02730DZ (intraluminal device), 02730EZ (intraluminal device, two) 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.
