About 025W4ZZ

025W4ZZ is the ICD-10-PCS code for a destruction procedure on the thoracic aorta, descending using a percutaneous endoscopic approach. In ICD-10-PCS, destruction means physical eradication of all or a portion of a body part by the direct use of energy, force, or a destructive agent.

In plain terms, this corresponds to other excision of vessels, thoracic vessels, the ICD-9-CM procedure title it maps to (38.65).

For a different body part, codes include 02544ZZ (coronary vein), 02554ZZ (atrial septum), 02564ZZ (right atrium), 02574ZZ (left atrium), 02584ZZ (conduction mechanism), 02594ZZ (chordae tendineae) and 16 more.

The same procedure with a different approach is coded 025W0ZZ (open) and 025W3ZZ (percutaneous).

It is an operating-room procedure in the MS-DRG logic for DRG 163 (Major Chest Procedures with MCC), DRG 164 (Major Chest Procedures with CC), DRG 165 (Major Chest Procedures without CC/MCC), DRG 270 (Other Major Cardiovascular Procedures with MCC), DRG 271 (Other Major Cardiovascular Procedures with CC) and DRG 272 (Other Major Cardiovascular Procedures without CC/MCC), under the surgical categories “Major Chest Procedures” and “Other Major Cardiovascular Procedures”.

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