About 03L33CZ
03L33CZ is the ICD-10-PCS code for a occlusion procedure on the right subclavian artery using a percutaneous approach with extraluminal device. In ICD-10-PCS, occlusion means completely closing an orifice or the lumen of a tubular body part.
In plain terms, this corresponds to other surgical occlusion of vessels, thoracic vessels, the ICD-9-CM procedure title it maps to (38.85).
For a different body part, codes include 03L03CZ (right internal mammary artery), 03L13CZ (left internal mammary artery), 03L23CZ (innominate artery), 03L43CZ (left subclavian artery), 03L53CZ (right axillary artery), 03L63CZ (left axillary artery) and 23 more.
The same procedure with a different approach is coded 03L30CZ (open) and 03L34CZ (percutaneous endoscopic).
With a different device, use 03L33DZ (intraluminal device) and 03L33ZZ (no device).
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”, “Other Major Cardiovascular Procedures”, “Stomach, Esophageal and Duodenal Procedures” and 1 more.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
