About 02B73ZK

02B73ZK is the ICD-10-PCS code for a excision procedure on the left atrium using a percutaneous approach (qualifier: left atrial appendage). In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a 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 02B70ZK (open) and 02B74ZK (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) and DRG 274 (Percutaneous and Other Intracardiac Procedures without MCC), under the surgical category “Percutaneous and Other Intracardiac Procedures”.

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