About 02QM4ZZ
02QM4ZZ is the ICD-10-PCS code for a repair procedure on the ventricular septum using a percutaneous endoscopic approach. In ICD-10-PCS, repair means restoring, to the extent possible, a body part to its normal anatomic structure and function.
In plain terms, this corresponds to other and unspecified repair of ventricular septal defect and other operations on septa of heart, the ICD-9-CM procedure titles it maps to (35.72 and 35.98).
For a different body part, codes include 02Q04ZZ (coronary artery, one artery), 02Q14ZZ (coronary artery, two arteries), 02Q24ZZ (coronary artery, three arteries), 02Q34ZZ (coronary artery, four or more arteries), 02Q44ZZ (coronary vein), 02Q54ZZ (atrial septum) and 23 more.
The same procedure with a different approach is coded 02QM0ZZ (open) and 02QM3ZZ (percutaneous).
It is an operating-room procedure in the MS-DRG logic for DRG 228 (Other Cardiothoracic Procedures with MCC) and DRG 229 (Other Cardiothoracic Procedures without MCC), under the surgical category “Other Cardiothoracic Procedures”.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
