About 02Q53ZZ
02Q53ZZ is the ICD-10-PCS code for a repair procedure on the atrial septum using a percutaneous 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 atrial septal defect, the ICD-9-CM procedure title it maps to (35.71).
For a different body part, codes include 02Q03ZZ (coronary artery, one artery), 02Q13ZZ (coronary artery, two arteries), 02Q23ZZ (coronary artery, three arteries), 02Q33ZZ (coronary artery, four or more arteries), 02Q43ZZ (coronary vein), 02Q63ZZ (right atrium) and 23 more.
The same procedure with a different approach is coded 02Q50ZZ (open) and 02Q54ZZ (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.
