About 05540ZZ
05540ZZ is the ICD-10-PCS code for a destruction procedure on the left innominate vein using an open 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.

The same procedure with a different approach is coded 05543ZZ (percutaneous) and 05544ZZ (percutaneous endoscopic).
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”.
