02NG0ZZRelease Mitral Valve, Open Approach

02NG0ZZ is the ICD-10-PCS code for a release procedure on the mitral valve using an open approach. In ICD-10-PCS, release means freeing a body part from an abnormal physical constraint by cutting or by the use of force.

In plain terms, this corresponds to open heart valvuloplasty of mitral valve without replacement, the ICD-9-CM procedure title it maps to (35.12).

For a different body part, codes include 02N00ZZ (coronary artery, one artery), 02N10ZZ (coronary artery, two arteries), 02N20ZZ (coronary artery, three arteries), 02N30ZZ (coronary artery, four or more arteries), 02N40ZZ (coronary vein), 02N50ZZ (atrial septum) and 20 more.

The same procedure with a different approach is coded 02NG3ZZ (percutaneous) and 02NG4ZZ (percutaneous endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 212 (Concomitant Aortic and Mitral Valve Procedures), DRG 216 (Cardiac Valve and Other Major Cardiothoracic Procedures with Cardiac Catheterization with MCC), DRG 217 (Cardiac Valve and Other Major Cardiothoracic Procedures with Cardiac Catheterization with CC), DRG 218 (Cardiac Valve and Other Major Cardiothoracic Procedures with Cardiac Catheterization without CC/MCC), DRG 219 (Cardiac Valve and Other Major Cardiothoracic Procedures without Cardiac Catheterization with MCC) and DRG 220 (Cardiac Valve and Other Major Cardiothoracic Procedures without Cardiac Catheterization with CC), under the surgical categories “Concomitant Aortic and Mitral Valve Procedures”, “” and “Cardiac Valve and Other Major Cardiothoracic Procedures without Cardiac Catheterization”.

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