About 027G3ZZ

027G3ZZ is the ICD-10-PCS code for a dilation procedure on the mitral valve using a percutaneous approach. 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 02703ZZ (coronary artery, one artery), 02713ZZ (coronary artery, two arteries), 02723ZZ (coronary artery, three arteries), 02733ZZ (coronary artery, four or more arteries), 027F3ZZ (aortic valve), 027H3ZZ (pulmonary valve) and 11 more.

The same procedure with a different approach is coded 027G0ZZ (open) and 027G4ZZ (percutaneous endoscopic).

With a different device, use 027G34Z (intraluminal device, drug-eluting) and 027G3DZ (intraluminal 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.
