About 027T44Z

027T44Z is the ICD-10-PCS code for a dilation procedure on the left pulmonary vein using a percutaneous endoscopic 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 027044Z (coronary artery, one artery), 027144Z (coronary artery, two arteries), 027244Z (coronary artery, three arteries), 027344Z (coronary artery, four or more arteries), 027F44Z (aortic valve), 027G44Z (mitral valve) and 11 more.

The same procedure with a different approach is coded 027T04Z (open) and 027T34Z (percutaneous).

With a different device, use 027T4DZ (intraluminal device) and 027T4ZZ (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.
