About 02QW4ZZ

02QW4ZZ is the ICD-10-PCS code for a repair procedure on the thoracic aorta, descending 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 suture of artery, the ICD-9-CM procedure title it maps to (39.31).

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 02QW0ZZ (open) and 02QW3ZZ (percutaneous).

It is an operating-room procedure in the MS-DRG logic for DRG 163 (Major Chest Procedures with MCC), DRG 164 (Major Chest Procedures with CC), DRG 165 (Major Chest Procedures without CC/MCC), DRG 268 (Aortic and Heart Assist Procedures Except Pulsation Balloon with MCC), DRG 269 (Aortic and Heart Assist Procedures Except Pulsation Balloon without MCC) and DRG 907 (Other O.R. Procedures for Injuries with MCC), under the surgical categories “Major Chest Procedures”, “Aortic and Heart Assist Procedures Except Pulsation Balloon”, “Other O.R. Procedures for Injuries” and 1 more.

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