About 05503ZZ
05503ZZ is the ICD-10-PCS code for a destruction procedure on the azygos vein using a percutaneous 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).

The same procedure with a different approach is coded 05500ZZ (open) and 05504ZZ (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”.
