About 02Q10ZZ

02Q10ZZ is the ICD-10-PCS code for a repair procedure on the coronary artery, two arteries using an open 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 02Q00ZZ (coronary artery, one artery), 02Q20ZZ (coronary artery, three arteries), 02Q30ZZ (coronary artery, four or more arteries), 02Q40ZZ (coronary vein), 02Q50ZZ (atrial septum), 02Q60ZZ (right atrium) and 23 more.

The same procedure with a different approach is coded 02Q13ZZ (percutaneous) and 02Q14ZZ (percutaneous endoscopic).

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.
