About 02BW0ZZ

02BW0ZZ is the ICD-10-PCS code for a excision procedure on the thoracic aorta, descending using an open approach. In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.

In plain terms, this corresponds to resection of vessel with anastomosis, aorta, the ICD-9-CM procedure title it maps to (38.34).

For a different body part, codes include 02B40ZZ (coronary vein), 02B50ZZ (atrial septum), 02B60ZZ (right atrium), 02B70ZZ (left atrium), 02B80ZZ (conduction mechanism), 02B90ZZ (chordae tendineae) and 16 more.

The same procedure with a different approach is coded 02BW3ZZ (percutaneous) and 02BW4ZZ (percutaneous endoscopic).

It is an operating-room procedure in the MS-DRG logic for DRG 268 (Aortic and Heart Assist Procedures Except Pulsation Balloon with MCC), DRG 269 (Aortic and Heart Assist Procedures Except Pulsation Balloon without MCC), DRG 356 (Other Digestive System O.R. Procedures with MCC), DRG 357 (Other Digestive System O.R. Procedures with CC), DRG 358 (Other Digestive System O.R. Procedures without CC/MCC) and DRG 907 (Other O.R. Procedures for Injuries with MCC), under the surgical categories “Aortic and Heart Assist Procedures Except Pulsation Balloon”, “Other Digestive System O.R. Procedures”, “Other O.R. Procedures for Injuries” and 1 more.

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