About 02L70ZK

02L70ZK is the ICD-10-PCS code for a occlusion procedure on the left atrium using an open approach (qualifier: left atrial appendage). In ICD-10-PCS, occlusion means completely closing an orifice or the lumen of a tubular body part.

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 02L73ZK (percutaneous) and 02L74ZK (percutaneous endoscopic).

With a different device, use 02L70CK (extraluminal device) and 02L70DK (intraluminal device).

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.
