About 02B70ZK

02B70ZK is the ICD-10-PCS code for a excision procedure on the left atrium using an open 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 02B73ZK (percutaneous) and 02B74ZK (percutaneous endoscopic).

It is a non-O.R. procedure that is part of the MS-DRG logic for DRG 250 (Percutaneous Cardiovascular Procedures without Intraluminal Device with MCC) and DRG 251 (Percutaneous Cardiovascular Procedures without Intraluminal Device without MCC), under the surgical category “Percutaneous Cardiovascular Procedures without Intraluminal Device”.

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