About 05L03ZZ
05L03ZZ is the ICD-10-PCS code for a occlusion procedure on the azygos vein using a percutaneous approach. 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 05L13ZZ (hemiazygos vein), 05L33ZZ (right innominate vein), 05L43ZZ (left innominate vein), 05L53ZZ (right subclavian vein), 05L63ZZ (left subclavian vein), 05L73ZZ (right axillary vein) and 19 more.
The same procedure with a different approach is coded 05L00ZZ (open) and 05L04ZZ (percutaneous endoscopic).
With a different device, use 05L03CZ (extraluminal device) and 05L03DZ (intraluminal device).
It is an operating-room procedure in the MS-DRG logic for DRG 270 (Other Major Cardiovascular Procedures with MCC), DRG 271 (Other Major Cardiovascular Procedures with CC), DRG 272 (Other Major Cardiovascular Procedures without CC/MCC), DRG 907 (Other O.R. Procedures for Injuries with MCC), DRG 908 (Other O.R. Procedures for Injuries with CC) and DRG 909 (Other O.R. Procedures for Injuries without CC/MCC), under the surgical categories “Other Major Cardiovascular Procedures” and “Other O.R. Procedures for Injuries”.
It has been valid since ICD-10-PCS took effect on October 1, 2015.
