About 02710ZZ

02710ZZ is the ICD-10-PCS code for a dilation procedure on the coronary artery, two 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 two vessels and open chest coronary artery angioplasty, the ICD-9-CM procedure titles it maps to (00.41 and 36.03).

For a different body part, codes include 02700ZZ (coronary artery, one artery), 02720ZZ (coronary artery, three arteries), 02730ZZ (coronary artery, four or more arteries), 027F0ZZ (aortic valve), 027G0ZZ (mitral valve), 027H0ZZ (pulmonary valve) and 11 more.

The same procedure with a different approach is coded 02713ZZ (percutaneous) and 02714ZZ (percutaneous endoscopic).

With a different device, use 027104Z (intraluminal device, drug-eluting), 027105Z (intraluminal device, drug-eluting, two), 027106Z (intraluminal device, drug-eluting, three), 027107Z (intraluminal device, drug-eluting, four or more), 02710DZ (intraluminal device), 02710EZ (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.
