027307Z 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, drug-eluting, four or more. 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 1 more, the ICD-9-CM procedure titles it maps to (00.43, 00.48, 36.03 and 1 more).

For a different body part, codes include 027007Z (coronary artery, one artery), 027107Z (coronary artery, two arteries) and 027207Z (coronary artery, three arteries).

The same procedure with a different approach is coded 027337Z (percutaneous) and 027347Z (percutaneous endoscopic).

With a different device, use 027304Z (intraluminal device, drug-eluting), 027305Z (intraluminal device, drug-eluting, two), 027306Z (intraluminal device, drug-eluting, three), 02730DZ (intraluminal device), 02730EZ (intraluminal device, two), 02730FZ (intraluminal device, three) and 3 more.
