About 02730TZ

02730TZ is the ICD-10-PCS code for a dilation procedure on the coronary artery, four or more arteries using an open approach with intraluminal device, radioactive. 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 four or more vascular stents, open chest coronary artery angioplasty and 2 more, the ICD-9-CM procedure titles it maps to (00.43, 00.48, 36.03 and 2 more).

For a different body part, codes include 02700TZ (coronary artery, one artery), 02710TZ (coronary artery, two arteries) and 02720TZ (coronary artery, three arteries).

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