About 03B40ZZ
03B40ZZ is the ICD-10-PCS code for a excision procedure on the left subclavian artery using an open approach. In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.
In plain terms, this corresponds to resection of vessel with anastomosis, other thoracic vessels and other excision of vessels, thoracic vessels, the ICD-9-CM procedure titles it maps to (38.35 and 38.65).
For a different body part, codes include 03B00ZZ (right internal mammary artery), 03B10ZZ (left internal mammary artery), 03B20ZZ (innominate artery), 03B30ZZ (right subclavian artery), 03B50ZZ (right axillary artery), 03B60ZZ (left axillary artery) and 23 more.
The same procedure with a different approach is coded 03B43ZZ (percutaneous) and 03B44ZZ (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”.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
