About 02Q34ZZ
02Q34ZZ is the ICD-10-PCS code for a repair procedure on the coronary artery, four or more arteries 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 repair of aneurysm of coronary vessel and other operations on vessels of heart, the ICD-9-CM procedure titles it maps to (36.91 and 36.99).
For a different body part, codes include 02Q04ZZ (coronary artery, one artery), 02Q14ZZ (coronary artery, two arteries), 02Q24ZZ (coronary artery, three arteries), 02Q44ZZ (coronary vein), 02Q54ZZ (atrial septum), 02Q64ZZ (right atrium) and 23 more.
The same procedure with a different approach is coded 02Q30ZZ (open) and 02Q33ZZ (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.
