About 027X3DZ

027X3DZ is the ICD-10-PCS code for a dilation procedure on the thoracic aorta, ascending/arch using a percutaneous approach with intraluminal device. 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, angioplasty of other non-coronary vessel(s) and 1 more, the ICD-9-CM procedure titles it maps to (00.40, 00.45, 39.50 and 1 more).

For a different body part, codes include 02703DZ (coronary artery, one artery), 02713DZ (coronary artery, two arteries), 02723DZ (coronary artery, three arteries), 02733DZ (coronary artery, four or more arteries), 027F3DZ (aortic valve), 027G3DZ (mitral valve) and 11 more.

The same procedure with a different approach is coded 027X0DZ (open) and 027X4DZ (percutaneous endoscopic).

With a different device, use 027X34Z (intraluminal device, drug-eluting) and 027X3ZZ (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 was added in FY2017, effective October 1, 2016.
