About 03Q03ZZ
03Q03ZZ is the ICD-10-PCS code for a repair procedure on the right internal mammary artery using a percutaneous 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).
For a different body part, codes include 03Q13ZZ (left internal mammary artery), 03Q23ZZ (innominate artery), 03Q33ZZ (right subclavian artery), 03Q43ZZ (left subclavian artery), 03Q53ZZ (right axillary artery), 03Q63ZZ (left axillary artery) and 23 more.
The same procedure with a different approach is coded 03Q00ZZ (open) and 03Q04ZZ (percutaneous endoscopic).
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. Procedures”, “Other Vascular Procedures”, “Other O.R. Procedures for Injuries” and 1 more.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
