About 02553ZZ

02553ZZ is the ICD-10-PCS code for a destruction procedure on the atrial septum using a percutaneous approach. In ICD-10-PCS, destruction means physical eradication of all or a portion of a body part by the direct use of energy, force, or a destructive agent.

In plain terms, this corresponds to excision or destruction of other lesion or tissue of heart, endovascular approach, the ICD-9-CM procedure title it maps to (37.34).

For a different body part, codes include 02543ZZ (coronary vein), 02563ZZ (right atrium), 02573ZZ (left atrium), 02583ZZ (conduction mechanism), 02593ZZ (chordae tendineae), 025D3ZZ (papillary muscle) and 16 more.

The same procedure with a different approach is coded 02550ZZ (open) and 02554ZZ (percutaneous endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 273 (Percutaneous and Other Intracardiac Procedures with MCC), DRG 274 (Percutaneous and Other Intracardiac Procedures without MCC) and DRG 317 (Concomitant Left Atrial Appendage Closure and Cardiac Ablation), under the surgical categories “Percutaneous and Other Intracardiac Procedures” and “Concomitant Left Atrial Appendage Closure and Cardiac Ablation”.

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