About 02Q74ZZ
02Q74ZZ is the ICD-10-PCS code for a repair procedure on the left atrium 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 repair of heart and pericardium, the ICD-9-CM procedure title it maps to (37.49).
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 02Q70ZZ (open) and 02Q73ZZ (percutaneous).
It is an operating-room procedure in the MS-DRG logic for DRG 270 (Other Major Cardiovascular Procedures with MCC), DRG 271 (Other Major Cardiovascular Procedures with CC), DRG 272 (Other Major Cardiovascular Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Other Major Cardiovascular Procedures” and “Other O.R. Procedures for Injuries”.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
