About 027G34Z

027G34Z is the ICD-10-PCS code for a dilation procedure on the mitral valve using a percutaneous 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 percutaneous balloon valvuloplasty, the ICD-9-CM procedure title it maps to (35.96).

For a different body part, codes include 027034Z (coronary artery, one artery), 027134Z (coronary artery, two arteries), 027234Z (coronary artery, three arteries), 027334Z (coronary artery, four or more arteries), 027F34Z (aortic valve), 027H34Z (pulmonary valve) and 11 more.

The same procedure with a different approach is coded 027G04Z (open) and 027G44Z (percutaneous endoscopic).

With a different device, use 027G3DZ (intraluminal device) and 027G3ZZ (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 319 (Other Endovascular Cardiac Valve Procedures with MCC) and DRG 320 (Other Endovascular Cardiac Valve Procedures without MCC), under the surgical categories “” and “Other Endovascular Cardiac Valve Procedures”.

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