About 027P04Z

027P04Z is the ICD-10-PCS code for a dilation procedure on the pulmonary trunk 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 single vessel, insertion of one vascular stent, insertion of drug-eluting stent(s) of other peripheral vessel(s) and 1 more, the ICD-9-CM procedure titles it maps to (00.40, 00.45, 00.55 and 1 more).

For a different body part, codes include 027004Z (coronary artery, one artery), 027104Z (coronary artery, two arteries), 027204Z (coronary artery, three arteries), 027304Z (coronary artery, four or more arteries), 027F04Z (aortic valve), 027G04Z (mitral valve) and 11 more.

The same procedure with a different approach is coded 027P34Z (percutaneous) and 027P44Z (percutaneous endoscopic).

With a different device, use 027P0DZ (intraluminal device) and 027P0ZZ (no device).

It is an operating-room procedure in the MS-DRG logic for DRG 252 (Other Vascular Procedures with MCC), DRG 253 (Other Vascular Procedures with CC) and DRG 254 (Other Vascular Procedures without CC/MCC), under the surgical category “Other Vascular Procedures”.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
