About 03Q04ZZ

03Q04ZZ is the ICD-10-PCS code for a repair procedure on the right internal mammary artery using a percutaneous endoscopic approach. In ICD-10-PCS, repair means restoring, to the extent possible, a body part to its normal anatomic structure and function.

In plain terms, this corresponds to suture of artery, the ICD-9-CM procedure title it maps to (39.31).

The same procedure with a different approach is coded 03Q00ZZ (open) and 03Q03ZZ (percutaneous).

It is an operating-room procedure in the MS-DRG logic for DRG 166 (Other Respiratory System O.R. Procedures with MCC), DRG 167 (Other Respiratory System O.R. Procedures with CC), DRG 168 (Other Respiratory System O.R. Procedures without CC/MCC), DRG 252 (Other Vascular Procedures with MCC), DRG 253 (Other Vascular Procedures with CC) and DRG 254 (Other Vascular Procedures without CC/MCC), under the surgical categories “Other Respiratory System O.R.
