About 027F4DZ

027F4DZ is the ICD-10-PCS code for a dilation procedure on the aortic valve using a percutaneous endoscopic 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 percutaneous balloon valvuloplasty, the ICD-9-CM procedure title it maps to (35.96).

For a different body part, codes include 02704DZ (coronary artery, one artery), 02714DZ (coronary artery, two arteries), 02724DZ (coronary artery, three arteries), 02734DZ (coronary artery, four or more arteries), 027G4DZ (mitral valve), 027H4DZ (pulmonary valve) and 11 more.

The same procedure with a different approach is coded 027F0DZ (open) and 027F3DZ (percutaneous).

With a different device, use 027F44Z (intraluminal device, drug-eluting) and 027F4ZZ (no device).

It is an operating-room procedure in the MS-DRG logic for DRG 231 (Coronary Bypass with PTCA with MCC), DRG 232 (Coronary Bypass with PTCA without MCC), DRG 273 (Percutaneous and Other Intracardiac Procedures with MCC) and DRG 274 (Percutaneous and Other Intracardiac Procedures without MCC), under the surgical categories “” and “Percutaneous and Other Intracardiac Procedures”.

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