About 02570ZK

02570ZK is the ICD-10-PCS code for a destruction procedure on the left atrium using an open 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 02573ZK (percutaneous) and 02574ZK (percutaneous endoscopic).

It is a non-O.R. procedure that is part of the MS-DRG logic for DRG 212 (Concomitant Aortic and Mitral Valve Procedures), DRG 233 (Coronary Bypass with Cardiac Catheterization or Open Ablation with MCC), DRG 234 (Coronary Bypass with Cardiac Catheterization or Open Ablation without MCC), DRG 250 (Percutaneous Cardiovascular Procedures without Intraluminal Device with MCC), DRG 251 (Percutaneous Cardiovascular Procedures without Intraluminal Device without MCC) and DRG 317 (Concomitant Left Atrial Appendage Closure and Cardiac Ablation), under the surgical categories “Concomitant Aortic and Mitral Valve Procedures”, “”, “Percutaneous Cardiovascular Procedures without Intraluminal Device” and 1 more.

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