About 03504ZZ
03504ZZ is the ICD-10-PCS code for a destruction procedure on the right internal mammary artery 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 03514ZZ (left internal mammary artery), 03524ZZ (innominate artery), 03534ZZ (right subclavian artery), 03544ZZ (left subclavian artery), 03554ZZ (right axillary artery), 03564ZZ (left axillary artery) and 23 more.
The same procedure with a different approach is coded 03500ZZ (open) and 03503ZZ (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”.
