About 02CW4ZZ

02CW4ZZ is the ICD-10-PCS code for a extirpation procedure on the thoracic aorta, descending using a percutaneous endoscopic approach. In ICD-10-PCS, extirpation means taking or cutting out solid matter from a body part.

In plain terms, this corresponds to procedure on single vessel, incision of vessel, aorta and Endarterectomy, aorta, the ICD-9-CM procedure titles it maps to (00.40, 38.04 and 38.14).

The same procedure with a different approach is coded 02CW0ZZ (open) and 02CW3ZZ (percutaneous).

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.
