About 02573ZK

02573ZK is the ICD-10-PCS code for a destruction procedure on the left atrium using a percutaneous approach (qualifier: left atrial appendage). 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, destruction, or exclusion of left atrial appendage (LAA), the ICD-9-CM procedure title it maps to (37.36).

The same procedure with a different approach is coded 02570ZK (open) and 02574ZK (percutaneous endoscopic).

It is a non-O.R. procedure that is part of 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.
